At present, consumers’ enthusiasm for off-road models is unprecedented, and off-road gameplay is more diverse. The old-fashioned Land Rover, with its excellent sales, proved its own strength. However, with the development of new energy and the change of intelligence, it has created a different gameplay from the era of fuel vehicles, and thus gained a high degree of heat. However, Dongfeng has been built with more than 50 years of experience in building cars, and has a military background gene. The strength of putting a number of military-grade technologies on civilian models cannot be underestimated, and the product strength and car experience of off-road models have been subverted. Then, it is necessary to have a more extreme off-road experience and to be more suitable for the actual car environment. How do you choose these cars?

A big gap between the experience of old-school fuel vehicles and new energy vehicles lies in the intelligent cockpit in the car. In terms of human-computer interaction, 917 hard-core off-road collides with intelligent technology. The 12.3-inch full LCD instrument screen, 15.6-inch central control screen, 12.3-inch passenger screen, HUD enhanced head-up display system and rear center armrest screen form an overall layout of five-screen interaction, which matches the new Confidence series 16-speaker sound system of Shangdan, and integrates the five senses from car control to entertainment, and can realize 5G remote smart phone, Bluetooth key, vehicle status monitoring and remote parking. At the same time, technologies to improve safety, such as parking security and infrared night vision, all come from the military, which are not only quite powerful, but also strengthen the sense of luxury and technology, making it more worry-free during the journey.

The Warrior 917 also has a full-scene intelligent voice interaction inside the car, which is simpler and more practical to operate. The multi-round dialogue function also makes the experience of voice control closer to the real communication scene, unlike the voice control of other models, which only gets a cold voice assistant response. At the same time, Warrior 917 also supports up to 2000+HMI pages to open customized voice, and personifies a variety of emotional voice interactive experiences, which can realize a rich and more personalized full-scene intelligent voice interactive experience. Looking up at the U8 cockpit, the visual experience of the three large screens is also quite excellent, but the functionality is not as comprehensive as that of the Warrior 917. However, the cockpit function of Land Rover Defender is still at a more traditional level, and its functionality and interactive experience are quite limited.

There are different opinions on the appearance, but the Warrior 917 inherits the aesthetic design of military industry and adopts the hard-core mecha style, which is quite full of military flavor. From the book data, it has the maximum ground clearance of 335mm, the maximum wading depth of 900mm, the maximum approach angle of 36.8, the maximum departure angle of 37.5 and the maximum through angle of 27.9, even 100% climbing slope (equivalent to 45) and 40% side slope (equivalent to 21.8).

In the era of electrification, the Warrior 917, as a new energy off-road vehicle, adopts the intelligent off-road chassis with global access and the M TECH intelligent off-road architecture. In addition to the intelligent adjustable air suspension, it also adds the CDC continuous damping adjustable vibration reduction system. Even the unpaved roads, washboards, gravel roads and other scenes during long-distance crossing ensure the stability and ride comfort of the vehicle. The dynamic domain control of VMC chassis can also improve the freedom of adjustment and driving experience. The Warrior 917, which is added with black technology, does not lose the look of U8 equipped with Yunqi -P system.

It has to be mentioned that the air suspension of Warrior 917 adopts BWI Jingxi AeroRide multi-stage intelligent adjustable air suspension. As a representative product of Jingxi high-end suspension, it is mostly used in Lamborghini, Ferrari, Porsche and other high-end models, which can achieve a lift speed of 5 mm/s, and the lift height is far more than 100 mm of similar products, reaching a fairly objective 150 mm, which brings considerable hardware redundancy to Warrior 917.

In addition to the chassis, the electric-driven Warrior 917 has more advanced functions and gameplay than Land Rover Defender. The Warrior 917 power system is driven by a larger battery pack, which makes the off-road capability more durable. Compared with the single-tooth ratio reducer, the 2-speed reducer is also harder, which can bring stronger off-road stability performance. In the actual experience, compared with the most eye-catching U-turn function, Bravissimo 917′ s rear-wheel steering by wire is more practical. As the first off-road vehicle equipped with rear-wheel steering technology, it has only a turning radius of 5.1m, allowing it to turn flexibly on narrow roads, and there is also a "crab-walking mode" that allows vehicles to drive laterally on special sections, greatly improving the ability of walking in the wild and cities.

China has a vast territory, various landforms, great differences between east, west, north and south, and complex off-road environment, so the durability and reliability of vehicles are extremely important. In this respect, U8 has passed four rounds of loop test of equivalent user driving 1 million kilometers and thousands of kilometers of real off-road road test, and accumulated more than 5 million kilometers of equivalent user mileage, with good durability.

However, even in the face of looking up to U8 with BYD’s technical endorsement, the Warrior 917, supported by Dongfeng’s experience in building cars for more than 50 years, did not fall in the wind. Warrior 917 is based on the durability test standard of military vehicles. Reliability and stability are the core strength of Warrior 917. As the only vehicle in China that has passed the durability test of "National Military Standard" (GJB).

The comprehensive field test of Bravissimo 917 shows that the reliability and durability of the whole vehicle are verified in 28 provinces, municipalities and autonomous regions across the country, covering more than 99.5% of the user’s use scenarios, including off-road conditions, mountain areas and mining areas, accounting for 50%, and covering the high temperature, cold and plateau three high tests of military off-road vehicles, and passing the military leap, obstacle impact and step climbing. Verified by the national standard of reliability and durability for four rounds of 1 million kilometers of military off-road vehicles, the strength reaches ten times that of ordinary passenger cars, and the actual mileage of equivalent users reaches 6 million kilometers beyond looking up at U8. The super coping ability in extreme environment can make the owner go wild, and Warrior 917 can always take the owner home safely.

In terms of safety, Warrior 917 decentralized the technology of military safety and reliability to civilian use, and the frame adopted an integrated internal high-pressure longitudinal beam with high strength and high rigidity, which was also the first passenger car in China. The frame structure adopted high-strength materials with a coverage of 600-800 MPa ≥85%, the tensile strength of the integrated thermoformed threshold structure reached 1500MPa, and the tensile strength of the thermoformed reinforced seat beam reached 1,800 MPa. The compressive strength of the roof is 110kN. Compared with the traditional longitudinal beam, the integrated internal high-pressure longitudinal beam of Warrior 917 improves the mechanical properties by 10% and reduces the weight of the system by 15%. Some beam structures are further reduced by aluminum alloy die casting, and the torsional stiffness is as high as 1180 nm/degree, which greatly improves the off-road handling of the whole vehicle and ensures excellent stability and durability under long-term use.

In contrast, although the brand-new Land Rover Defender has a body structure made of high-strength aluminum alloy, the "all-terrain platinum geometric body" has laid a solid foundation for it to conquer bad road conditions, but the brand-new Land Rover Defender has been replaced by a body, and the body stiffness in extreme off-road environment will still be slightly inferior to the structural strength.

As a new energy off-road vehicle, many people will worry about battery safety and whether it can meet the extreme situation that off-road vehicles need to face. The battery pack box of Dongfeng Warrior 917 adopts military aluminum alloy frame with lightning protection and energy absorption honeycomb structure, equipped with 1500 MPa integrated stamping high-strength bottom guard plate and multi-layer composite materials, which can ensure the safety of the vehicle under extreme working conditions such as bottoming and rubbing. The side surface of the battery box is also made of hot-formed high-strength steel plate exceeding 1500Mpa, which further effectively protects the safety of the battery pack.

In addition, the pure electric version of Warrior 917 also comes standard with front and rear 1800Mpa high-strength steel plate bottom guards; The extended-range version also comes standard with 1800Mpa high-strength steel plate bottom guards for the front and fuel tanks, and can also support the optional installation of 8mm magnesium-aluminum alloy front and rear guard plates, which can well avoid the damage caused by bumping the bottom of the car during high-strength off-road, and can be more confident when facing more complicated road conditions. IP67/IPX9 protection grade is also adopted in the key controller of the whole vehicle, and IP68 dustproof and waterproof grade is adopted in the part of the three electric systems, which can easily cope with the challenges brought by harsh terrain environment without maintenance even after wading.

In addition to its strong off-road strength, one of the highlights of Warriors 917 lies in its full personalization and off-road expansion ability. Off-road vehicles are partners rather than pure tools for players. It supports high-end customization and personalized modification, and provides rich personalized options and customized modification services for vehicle interior trim, exterior trim and chassis parts, such as DINAMICA? environment-friendly suede ceiling, 20-inch forged wheel hub/anti-falling wheel hub with all-terrain tires, roof expansion platform kit, electric winch, electric side pedal and simulated sound waves, etc., all of which can achieve high personalized customization and meet the differentiated scene requirements of one person and one car user, with high playability and such freedom.

Moreover, Warrior 917 also built three stylized official optional kits around the user’s differentiated scene requirements for consumers with various needs, aesthetics and uses to choose, and truly formed a customized product of "one car, one price, one person, one car", which can let players play by themselves and make a group of off-road veterans easily show their unique personality in the off-road circle.

Compared with the old-fashioned fuel off-road vehicle, the Warrior 917 is more entertaining, smarter and easier off-road, and brings a better car experience. Compared with looking up at U8, Warrior 917 is not only hard-core enough for off-road, but also convenient for urban travel. In addition, as a brand that meets the operational needs of the army, Warrior’s aesthetic design and national military standards are the reasons why people used to see Warrior’s cars on the road to admire and admire them, which represents the manufacturing level of off-road vehicles recognized by the state. Finally, the high customization differentiation and the freedom of optional installation make it full of playability. In the off-road circle, it can be recognized by off-road old guns by highlighting the taste and quality. Warrior 917 brings military-grade hard-core products into civilian use, satisfying more people’s military dreams and off-road dreams.

　　Dinghuili Primary School takes The Lonely Brave as a project-based learning course for teaching and research.

　　Children’s understanding of the "lone brave" (CCTV screenshot)

　　Paintings by students of Dinghuili Primary School

　　With the attention of the People’s Daily and other media, "The Lonely Brave" is really a hit.

　　The reason why it became popular again was that people suddenly discovered that this online game theme song, which was originally sung by Hong Kong singer Eason Chan, caused a "viral spread" among primary school students who were mainly born after 10, and changed from BGM of various short videos to "joint code" for contemporary primary school students.

　　However, to what extent is The Lonely Brave popular among young people? What kind of transmission path did you follow? What kind of mood of the times is conveyed behind the explosion? Is all this accidental or inevitable?

　　phenomenon

　　"Can all your children sing" The Lone Brave "?"

　　Parents:

　　The lone brave "from person to person"

　　"Your children can sing" the lone brave "? My son can’t sing, will he be isolated? " In a WeChat group that gathered parents of the post-80s generation, some parents asked slightly anxiously. Among the parents and friends who answered him, eight out of ten said, "I can sing." A parent comforted and said, "Don’t worry, your child won’t do it now, but he will in a few days." Indeed, there has been a "human-to-human" phenomenon in the song "The Lone Brave".

　　Liuli overheard her humming the tune of this song on her way home and asked her, "Where did you know this song?" The daughter said, "All the students can sing."

　　A few days later, Liuli listened to her daughter sing the tune of "The Lonely Brave" at home, but the lyrics were slightly different. His daughter told him that it was a "dream version" of The Lone Brave.

　　The original "Lone Brave Man" has been revised several times, and many funny versions have appeared, which are sung among children. The so-called "dream version" is actually a version of the lyrics that dreams of not going to school, not doing homework, eating snacks and playing games.

　　Liuli found that, judging from the reaction of friends in the group, most children in primary school or even kindergarten can sing The Lonely Brave, and even if they can’t sing, they will hum the melody of the climax.

　　At first, some parents thought that their children learned from music lessons, but in the discussion, they found that the songs sung between children did not come from the classroom, but from the Internet.

　　"My children didn’t know it at first, but later they learned it from the children of the big brothers. His children were loosely managed and always went to Tik Tok." A parent gave evidence of his observation. Another parent said that both children in his family can sing "The Lone Brave". The boss learned it from the second child, and the second child played a role-playing game called "Mini World", which contained this song.

　　Parents with a second child found that "The Lonely Brave" was mainly sung in the middle and lower age stages of middle and large classes or primary school students in kindergartens. "My boss is already in the first grade, and it bothers her third-grade brother to hum this song every day."

　　Teacher:

　　Interact with students with The Lone Brave

　　Children’s love for "The Lone Brave" began during the epidemic prevention and control this spring. An ancient teacher in the first grade of a primary school told the reporter of Beiqing Daily that she would play some songs to the students during recess. When asked what songs they wanted to listen to, most of the children would say in unison: "The lone brave."

　　Teacher Gu has heard this song on the Internet before, but I didn’t expect the first-year students to be interested in this kind of pop music. When she plays this song during the break, some children will jump to the rhythm unconsciously, and almost all the boys in the class will sing at the climax.

　　Later, Teacher Gu saw on the Internet that a child used the lyrics of "The Lonely Brave" to check the secret code. She also learned to check with the students several times. "The students will be very happy to cooperate and feel that the teacher is very close to them."

　　Students also have different opinions about why they like the song "The Lonely Brave". Some students say that the lonely brave is an assassin, very elegant and handsome; Some students say that this is a song depicting laborers; Some students said that this is a doctor’s song to kill the virus.

　　The ancient teacher said that from the communication with the students, she felt that the children liked the song "The Lonely Brave", which should have originated from an online video during the epidemic. In the video, a swordsman killed the virus with a sword, and BGM was the song "The Lonely Brave". Therefore, the children think that this swordsman is very brave and has a chivalrous spirit, which can defeat the virus and make everyone’s life return to normal.

　　Liu Ying, a music teacher at Dinghuili Primary School in Haidian District, told Beiqing Daily that she heard the children singing this song in her own music class, and some children mentioned "The Lonely Brave" when sharing their favorite songs.

　　As a music educator, Liu Ying analyzed that the melody of "The Lonely Brave" is very suitable for children to learn to sing, with a fast rhythm and a strong sense of rhythm, which makes children easy to accept, and the rhythm and lyrics are sonorous, giving people an inspiring feeling, which is also in line with children’s psychological expectations when pursuing future hopes.

　　Liu Ying said that what impressed her most was the sentence in the lyrics, "Who said that a hero is standing in the light". Because every child has a heroic dream, this song touched the children’s dreams, and let the children know that heroes are not only firefighters, policemen and doctors, but also teachers and parents around them.

　　Because of the popularity of this song, the music teachers in Dinghuili Primary School also took the song "The Lone Brave" as a project-based learning course for teaching and research. According to the different age groups of students, the teachers asked the students to interpret "The Lone Brave" with different instrumental music and dance methods, which also achieved good art teaching results.

　　spread

　　Topics related to "The Lonely Brave" have rushed to the hot search list several times.

　　Wave 1:

　　After the launch, many stars covered it.

　　In addition to "going out of the circle" among younger people, the popularity of the song "Lonely Brave" on major social platforms has also continued to rise recently, and topics related to "Lonely Brave" have rushed to the hot search list several times.

　　The reporter of Beiqing Daily found that the spread path of the song "The Lonely Brave" can be roughly divided into the following four stages: attracting many entertainment stars to cover, entering the student group, serving as the "joint code" for adults and children, and being named by the mainstream media.

　　On November 8th, 2021, the Chinese theme song "Lonely Brave Man" of the game League of Legends derivative animation League of Legends: Battle of Two Cities was officially launched. The song was written by Tang Tian, composed by Qian Lei and sung by Eason Chan.

　　The reporter of Beiqing Daily found that Phoenix Legend, Angela Zhang, Xin, Tengger singer, A Duo and many other stars had covered "The Lone Brave Man" on the show or in the recording studio only about half a year after the song was launched.

　　In a variety show on Zhejiang Satellite TV, Yang Kun, Rainie Yang and J.zen sang "The Lone Brave", and Weibo’s topic "Yang Kun’s lone brave opens his mouth" was read by 7.888 million people.

　　In the program "Braving the Wind and Waves", Na Ying, Xu Ruyun, Sitar tan and Jessica sang "The Lonely Brave", and Weibo’s reading on three related topics reached 140 million.

　　Wave 2:

　　Infiltrate into the student group

　　While the entertainment circle is "broken", The Lonely Brave is also widely circulated among students. There is a chorus of the whole class, a performance, and a table dance of this song specially arranged by the teacher for the students. The reporter of Beiqing Daily found that as early as mid-March this year, there was a discussion on "Why do primary school students like" The Lone Brave "on the Internet.

　　Until now, you can still see a lot of hot content when you open the major platforms to search for the keyword "The Lone Brave" for primary school students, which is also the most intuitive embodiment of the song "The Lone Brave" successfully entering the student group.

　　The third wave:

　　Become a child’s "joint code"

　　After "The Lonely Brave" became popular among students, the reporter of Beiqing Daily also noticed that many self-media bloggers went to the streets to look for children’s "secret code". Many times, the phrase "I love you to walk alone in the dark alley" just started, and the children began to sing "I love the way you don’t kneel".

　　Interestingly, on April 2, a young man in Kaili, Guizhou Province played drums to exercise his courage at the school gate, but he did not expect to attract a group of primary school students to watch. Later, everyone sang "The Lone Brave" along with the rhythm. The video has 474,000 likes.

　　Wave 4:

　　Be "named" by the mainstream media

　　In addition to the strong communication power of all parties, the attention of major media has also become an important reason why the song "The Lonely Brave" has become popular all over the network. In the past two months, The Lonely Brave has been named by the mainstream media.

　　On May 26th, the People’s Daily official micro published an article entitled "The Solitary Brave Writer Responds to the Struggler who Warmly Moves Forward with Songs as Children’s Songs", and the topic was read 260 million times. On May 8, People’s Daily and many other media released "Nine Ancient Musical Instruments Unlocking the Ancient Style Lonely Brave", with a topic reading of 5.094 million in Weibo; On July 4th, People’s Daily WeChat WeChat official account published a tweet "Why do primary school students love to sing ‘ The lone brave ’ ? ",reading 100,000+.

　　sound

　　Good production, copyright, platform and capital win together.

　　"A song is on fire, and everyone is rushing to make their own version, which is now the norm in the industry." A music industry practitioner told the reporter of Beiqing Daily about the industry logic he observed. "Everyone is rushing to make a flow of money." A short video industry practitioner added.

　　"The lone brave is really a high-quality song. The lyrics and songs are excellent, and the chord direction is not vulgar. " A post-90 s platform musician told the reporter of Beiqing Daily, "It is normal for children to like such positive energy songs. In addition, the Chinese theme song, which was originally the game animation of League of Legends, also covers a large number of gamers. They are all young people and have a great overlap with the student group."

　　Analyzing the reasons for the popularity of this song, all four interviewees said that as the theme song of League of Legends game animation, the popularity of Lonely Brave has a lot to do with the ability of various copyright owners, music platforms and video platforms to spend a lot of money: "Now a song is not popular, 80% depends on money, and 20% depends on luck." The music critic told the reporter of Beiqing Daily, "The copyright competition of the three major Internet companies with music business has become fierce. Many times, everyone will push their own copyrighted songs and give little traffic to competing platforms. This is already a common practice in platform competition. Because every time it is played, there will be a corresponding income. "

　　A short video industry practitioner said, "When a song is hot, online celebrity covers and shoots short videos to get hot, and MCN will throw money at the back to push the content into a larger traffic pool for the sake of traffic. This created the popularity and visibility of the whole network. In the end, this song was heard by primary school students, and they began to sing spontaneously, which was a greater victory for traffic. "

　　Some media also said that the cultural logic of explosive fire is that experienced professionals enter the online pop music arena. "Of course, The Lone Brave can do this because the traditional record industry is behind it. Qian Lei, who has rich production experience and many masterpieces, is the producer, and Tang Tian, a female lyricist with many masterpieces, writes lyrics. Her personal experience of fighting cancer is also well known in the spread of The Lone Brave. In other words, the fire of "The Lone Brave" spread all over the network, and it also means that professionals will leave. " Titanium media reported that.

　　Chaoliu archives

　　The Lonely Brave carries inspirational genes from its birth.

　　The popularity of "The Lonely Brave" made the original singer Eason Chan somewhat unexpected. He personally sent Weibo and said, "I heard that I sang a children’s song."

　　According to Qin Yanqiong of Nanjing Normal University’s paper "A comprehensive discussion on nursery rhymes — — From Literature to Pedagogy, the word "children’s songs" originated from Zhou Zuoren: "children’s singers, children’s songs, Gu Yan nursery rhymes". Therefore, it is considered that nursery rhymes are the modern names of nursery rhymes.

　　Children’s songs and nursery rhymes are part of folk songs, oral poems created by the general public, and the true reflection of their real life, thoughts, feelings and psychological wishes in rhythmic and musical oral language. The popularity of ballads is actually a form of folk literature expression from ancient times to the present, which is closely related to the historical situation of social development.

　　Chu Zhaohui, an education expert and researcher at the China Academy of Educational Sciences, told the Beijing Youth Daily that children have a stage of growth and development. At the age of 4, it is a critical period for their personality growth and development, and they have obvious perception of the outside world. The popularity of this song is closely related to the external growth environment of minors now.

　　Nowadays, parents and teachers of children mostly urge their children to get better grades, and their emotional needs have not been met. So they need a certain channel to vent, and this song meets this need.

　　"If the emotion is not (satisfied), the child’s life experience will cross the actual age." Chu Zhaohui believes that families and schools should further reduce the pressure on children and let them "return to childhood".

　　Chu Zhaohui said, "Each of our children is like a ball. When you throw it on what kind of wall, it will bounce back. This is a very normal phenomenon and should not be over-interpreted. The song "The Lonely Brave" is a reflection of the emotional state of children. "

　　As a music teacher, Liu Ying also has a social view on the popularity of The Lone Brave. She thinks that good music songs must conform to the social development trend before they can become hot spots.

　　Under the background of the great changes in the past century and the national fight against the epidemic, the forceful rhythm and lyrics full of positive energy conveyed by Lonely Brave bring more encouragement to children growing up in this environment.

　　In addition, Liu Ying believes that there is a touching story behind the song "The Lonely Brave". Tang Tian, the lyricist of the song, is a woman who has been fighting cancer for ten years. She is not only the creator of lyrics, but also the hero of the song story. It can be said that the song "The Lone Brave" has an inspirational gene since its birth.

　　At present, it is impossible to fully count how many versions of this song there are. As many children feel, the lyrics of The Lonely Brave contain courage, blood, comfort and healing. These feelings make this song resonate with more people and give the lonely and brave people room for multiple interpretations.

　　Version evolution

　　Original version: Chinese theme song of the game League of Legends derivative animation League of Legends: Battle of Two Cities.

　　Cover: In 2022, it was successfully "out of the circle" and was covered by many big musicians and famous musicians.

　　Children’s songs: A kindergarten in Xuchang, Henan Province set the Lonely Brave as a wake-up bell; A doctor in Zhuhai, Guangdong, used the "Solitary Brave" to "check the code" to eliminate the fear of the little boy who treated his teeth; In a primary school in Kunming, Yunnan, after a class lost the tug-of-war competition for three years in a row, the teacher sang "The Lone Brave" to motivate the students.

　　Adaptation: Holiday Edition, Homework Edition, Altman Edition and Happy Edition, which are popular among children; It has been changed into an "industry edition" by police, doctors, miners, firefighters, prosecutors and township civil servants.

High-tech, burning my childhood.

"Clairvoyance" helps to tear off "psoriasis"

During the Spring Festival this year, I showed my "unmanned aerial vehicle system operator certificate" in front of my family last year, which reminded me of the first time I used drones to collect evidence.

In Shangxi Town, Yiwu City, there is a medium-sized water conservancy project-Yankou Reservoir, which is mainly used for irrigation and combined with comprehensive utilization of flood control and power generation. It is also a first-class drinking water source protection area in Yiwu City, where water resources are scarce. In 1996, a company in Yiwu was allowed to develop and operate a holiday resort in Yankou Reservoir. In 1999, on the basis of legally approved land use, the company occupied more than 13,000 square meters of land in the secondary protection zone along the lake, built ballroom, restaurant and other facilities, occupied forest land and agricultural land to build cabins, illegally occupied more than 950 square meters in the basic farmland protection zone and forest land to build multi-storey buildings and other facilities, and rented the land within the reservoir protection zone that it had no right to use to others for building villas along the lake in the form of long-term lease and illegal profit. These illegal buildings have become "psoriasis" that has been firmly stuck in Yiwu’s precious water conservation zone for 17 years.

In October 2017, our hospital received a report from the masses, and immediately formed a working group in the people’s bank of China to investigate. After full intervention, special investigation and on-the-spot investigation, we basically found out the fact that the company illegally occupied land, and then started the pre-litigation procedure of public interest litigation.

In order to further consolidate the evidence and fully understand the comprehensive three-dimensional situation of the occupation of Yankou Reservoir, our hospital decided to use drones for investigation and evidence collection. On the morning of December 11, 2017, two drones officially started their "first show". I am in charge of operating one of them. Although I have been trained before, I still feel a little uneasy because I am flying on the lake, for fear that I will make a mistake in operation and lead to "explosion". Install, start and operate the rocker, the wing rotates at high speed, and the drone takes off quickly. I first let the drone climb to a suitable height, and then let it fly slowly over the reservoir. Through the high-definition camera equipped on the drone, the evidence of illegal buildings built along the reservoir was locked by aerial high-definition aerial photography, and the images were transmitted to the remote command center of our hospital in real time through the 4G transmission system. The remote command center conducted real-time command and monitoring through the equipped individual law enforcement instrument. After two battery replacement flights, the drone took nearly 100 high-definition photos and 7 high-definition videos, further fixing the illegal facts of the company, and the "first show" was a complete success. Promoted by the pre-litigation procuratorial suggestions of our hospital, and attached great importance to by the Party committee and government, in late December, tens of thousands of square meters of illegal buildings were forcefully demolished.

Now, the UAV has become the "clairvoyance" of our hospital, and it has played a great role in handling public interest litigation cases. Since late December 2017, two drones have taken off 24 times, and conducted aerial surveys on illegal buildings, water resources and environment, and forest mines through remote command aerial photography. 350 aerial forensics photos have been taken and 56 high-definition videos have been taken. It also helped to successfully file 6 public interest litigation cases in the first week after the opening of 2018. And I, while feeling the joy of operating the drone, look forward to the wonderful and continuous climax of "prosecution+high technology".

(Oral: Yiwu People’s Procuratorate Zhang Dailei)

Small software computing big data

As usual, I turned on the computer as soon as I got to work. Looking at the three softwares "Access", "Excel" and "Unified Business Application System" lined up in sequence on the computer desktop, I couldn’t help feeling a little smug. I didn’t expect that I, who was born in liberal arts or an insulator of science and technology, actually mastered the latest new technology-big data analysis.

Two years ago, after eight years of public prosecution, I was entrusted by the leaders of the hospital as the director of the newly established case management office. At that time, the newly born function of case management was more "logistics service", which covered many functions such as case receiving and dispatching, inquiry and reception, but it was the case quality supervision function that allowed me to leave the public prosecution seat willingly, which covered my legal belief from the original single case to the whole hospital.

Full of ambition, I excitedly opened the "unified business application system". After some wits and n calls for help, I was completely dumbfounded. This software is the most important process monitoring means for case quality supervision, and only sets the early warning of overdue deadline for handling cases, and other problems can only be queried layer by layer by opening the case-by-case card.

What should I do? As a grass-roots hospital with an average annual case volume of more than 4,500 cases, it is tantamount to finding a needle in a haystack by opening cases one by one and finding irregularities in handling cases! More urgently, at that time, the disclosure of legal documents was not up to standard, and it was urgent for the case management department to find undisclosed documents and urge the undertaker to disclose them in time. This requires us to find out the cases of undisclosed documents from the 3200 cases that have been prosecuted.

The post-90 s young man in the department rolled up his sleeves and said to me, "Director, it’s just 3,200 cases. We have many people in charge of the case, and each person can compare 400 cases one by one, and it can be done in less than three days." The young man’s drive is worthy of recognition, but now it’s the 21st century, how can he still rely on crowd tactics?

When I was about to make a decision to work overtime for all employees, I learned that the Access software under the Office has the function of data comparison, that is, the same content in two excel tables is compared through the function of "finding mismatches" to filter out inconsistent content. Under the guidance of a large number of tutorials and videos, after several days’ efforts, we finally worked out the list of cases with effective judgment and the list of cases that have been made public by using the unified business application system, and imported it into Access software for comparison, so as to screen out the list of cases with effective judgment but without public legal documents with one click. It’s amazing! It takes only ten minutes before and after to complete the work of the whole department for several days.

With the deepening of the reform of judicial responsibility system, the effective supervision and judicial standardization of post-based prosecutors have become the main battlefield of big data analysis in the new era. We have included the protection of litigation rights, compulsory measures, property involved, judgment review, case card filling and other contents into the data comparison and analysis, which has expanded the breadth and accuracy of process monitoring. At the same time, the irregular problems found in monitoring are reported regularly every month, so that the business department can continuously improve the standardization level of handling cases. For example, the irregular problems in the second quarter of 2017 decreased from 925 in the previous quarter to 215. Unexpectedly, a small piece of software has such a great role.

With the full application of big data analysis technology, the case management department of our hospital has not only realized the full-process, real-time and dynamic monitoring and early warning of key nodes of more than 4,500 cases every year, but also established a system of "daily patrol, weekly visit and monthly report" to urge and rectify, carried out special inspections on irregular behaviors, promoted the transformation and upgrading of case management from "logistics service" to "business management", and effectively improved the quality and efficiency of case handling.

Black technology in the laboratory

"Is there any result in the comparison of portrait identity in my case?"

"This is the technical report, please have a look."

"Really useful! Ok, you can arrest! "

I was relieved to see the undertaker walk out of the laboratory with the report. It was already 8: 00 pm. This is the third case of image processing technical assistance this month. Now, once prosecutors in our hospital encounter more difficult and complicated cases, they often think of going to the electronic data laboratory.

Dating back to 2014, with the exposure of CCTV’s March 15th party, the case of Hangzhou Guangqi Trading Co., Ltd. selling expired food surfaced. However, the handling of the case is not smooth. Due to the changes in the confessions of several suspects, this case, which is widely concerned by media public opinion, faces the risk of insufficient evidence. At the critical moment, the undertaker came to our laboratory for help. The case was highly concerned by the society and it was also a food safety issue. We didn’t dare to slack off for a moment, and quickly recovered and extracted the objective evidence such as chat records and counterfeit quality inspection documents used to communicate with the suspect’s computer through technical means. Finally, the case was successfully prosecuted. Since then, we have restored the P2P platform involved in the case through investigation experiments, established the structure and organization of criminal gangs through data collision, searched for clues of pursuit and prosecution through analysis and search, and took the lead in carrying out image processing technical assistance such as fuzzy image clarification and portrait identity comparison in the province. Since 2015, the laboratory has provided technical assistance to various business departments for 437 times, and the acceptance rate of electronic evidence issued by us and submitted to the court is as high as 100%.

In recent years, the average number of cases handled by the criminal prosecution department in our hospital has reached more than 200, and the laboratory has become more and more busy. Faced with the prominent contradiction of too many people and too few cases, I often fall into meditation. How can procuratorial technology provide better technical support for the case-handling department?

In 2016, our hospital became a pilot hospital of intelligent speech recognition system, which changed the traditional mode of manual input while interrogating. Also in that year, during a training course for the technical section chief of the whole province, I came across the prototype of the intelligent case-handling system of a company in Beijing, and suddenly realized that this was the best combination of big data, artificial intelligence and procuratorial case handling. The vitality of technology is based on business. Only when technology and business are deeply integrated can the effect of 1+1>2 be collided. Back at work, we started to implement this idea non-stop, and set up a five-person R&D team of "technology plus public prosecution". After numerous red-faced "quarrels" and in-depth research and discussion, the intelligent public prosecution auxiliary system was finally successfully launched.

At present, the intelligent public prosecution assistant system plays an important role in handling simple cases such as dangerous driving and theft, and all documents can be generated with one click, including the conclusion report. Without a large number of simple cases, prosecutors can focus more on the handling of difficult and complicated cases. After the system was popularized in the whole province, it has assisted in handling 2607 cases in just four months.

Of course, this is only a small first step. Inspired by Alpha Dog, we are exploring the algorithm of using artificial intelligence to predict the occurrence probability and growth trend of similar cases. I believe that in the near future, there will be more "black technology" in the laboratory.

Thanks to high technology

"Broiler"? It is not a fat chicken waiting to be fed in a henhouse, but an image statement in the Internet field, also known as a puppet machine, which is usually used by hackers as a machine for DDOS attacks. Not long ago, I came across such a "broiler" case that gave me a headache. Fortunately, with the help of high technology, I solved this complicated case in five days.

That day was Friday, and a case came early in the morning. There were several thick files, the cover of which was written with the charge of "providing intrusion and illegal control of computer information system programs and tools". The report on arrest wrote: "The criminal suspect Liu rented overseas cloud servers, attack traffic and front-end site source programs and database templates, and deployed them on overseas cloud servers after modification, set up front-end sites for DDOS attacks, and made mobile phone applications … A string of question marks popped up in my mind.

After receiving the case on Friday, there are only five working days left after a weekend, and the arraignment is the first "obstacle". Time is tight, tasks are heavy, and there are still many things to know. So, I thought of the remote video message system opened in our hospital. On Monday morning, after mastering the case file, my colleagues and I started arraignment. One end was set up in the remote arraignment room in the hospital and the other end was set up in the detention center. I sat in the remote arraignment room without leaving home and completed the interrogation of the suspect. It turned out that the criminal suspect took advantage of the loopholes in the computer information system, pretending to be the attacked object and sending requests to many computers, so that a large amount of information was fed back to the attacked object, which led to the paralysis of the attacked object, which was an upgraded version of DDOS attack.

In order to enhance perceptual knowledge, I came to the electronic data laboratory of our hospital again. According to the case, my colleagues in the technical department simulated the whole process of DDOS attack for us, which made me have a clearer perception of the criminal suspect’s modus operandi. In handling the case, I found that the list of attack services purchased from criminal suspects and the attack records had not yet been obtained. After communicating with the public security organs and using remote electronic evidence exploration, the investigators joined forces to investigate and arrest, and the required evidence was delivered to me the next day.

But another "roadblock" has appeared. How to define it? The criminal suspect adopts NTP reflex amplification attack mode, which is different from the traditional attack mode of controlling puppet machine in the past. It seems inappropriate for the public security organ to report the crime of arrest. But what should be charged? When I was at my wit’s end, it suddenly occurred to me that there was an "expert database" in the "intelligent investigation and supervision auxiliary case handling system", and there were experts from all walks of life, including Alibaba security department executives, who signed contracts with our hospital and could answer questions for us. I contacted one of the technical experts, and he patiently introduced me to the development history and attack methods of cyber attacks, which opened my mind: the NTP reflection amplification attack method in this case is more appropriate to be characterized as "the crime of destroying computer information systems".

Next, I entered the intelligent investigation and supervision auxiliary case-handling system in the hospital. Through the connection with the platform of "integration of politics and law", the electronic files such as transcripts made by public security organs have been shared here, and I only need to copy and paste to complete the production of marking transcripts. For some handwritten transcripts that don’t have an electronic version, I use iFLYTEK voice input system. Just read the transcripts into the microphone and the text content will pop up on the screen.

Thanks to high technology, within five working days, our hospital made a decision to approve the arrest of the suspect in this case according to law.

"wisdom+supervision"

On February 25th this year, I opened a judicial APP software developed by the judicial administrative organ, which is mainly used for all-weather supervision of community corrections personnel, logged in with the procuratorial port, and conducted an online inspection of the corrections of community corrections personnel within my jurisdiction. It was found that there were "abnormal situations" in all two prisoners in Lingzhi Town, Yuecheng District, Shaoxing City. One of the community prisoners was suspicious. Although he had a leave record, the location record appeared in a village in Zhuji City many times from February 22 to 25. From the location and time of location, it didn’t look like seeing a doctor. The other is that in a month-long period, there were more than 1,500 phone shutdown records.

How can you go to such a remote place to see a doctor instead of going to several local big hospitals in Shaoxing? Why are there so many shutdown records? Is there something hidden behind them? With these questions, I immediately reported to the director of the department. After analysis, we believe that this situation is very important, and it is necessary to carefully verify the specific conditions of these two prisoners.

"Hello, this is the criminal execution and prosecution department of Yuecheng District Procuratorate. According to the positioning records of the platform, we found that a correctional officer supervised by you has been in a village in Zhuji in recent days, which may be different from the reason why he asked for leave to see a doctor before …" I immediately called the judicial staff of Lingzhi Town to ask the other party to verify the specific situation.

At the same time, the director of the Department suggested that the A-PDA criminal execution procuratorial platform designed by Shaoxing Procuratorate, namely link weight analysis (a), task intelligence generation (p), on-site mobile phone inspection (d) and intelligent feedback of results (a), be used to conduct a comprehensive screening of the supervision of community corrections personnel in the judicial office of Lingzhi Town to see if there is any "crossing the border" situation of fabricating false reasons.

I immediately took the A-PDA mobile phone task of the criminal execution and prosecution platform, and went to the Lingzhi Town Judicial Office for inspection and verification with my colleagues. The staff of the judicial office immediately contacted the two prisoners. After investigation, it was found that one of them thought that his illness had gone to several big hospitals in Shanghai and Hangzhou, and it was not effective. On the advice of relatives, he went to an old Chinese medicine clinic in Zhuji countryside for treatment. The other person was unable to turn on the phone because the phone fell into the water some time ago, and did not replace the new phone in time. After understanding the situation, we urged the judicial office to educate the two prisoners and asked them to report their activities in time.

At the scene, my colleagues and I uploaded the examination results of these prisoners to the A-PDA mobile phone in the form of photos and words, and evaluated the inspection link as qualified and good. A-PDA criminal execution procuratorial system will analyze the results of each inspection link, and the unqualified link will be the focus of the next task inspection. At the same time, after each inspection, the system will make objective inspection results according to the weight of each inspection link, and compare it with other judicial offices to form a columnar table, which is very intuitive and effective.

Since the end of December last year, we have checked the community corrections of 311 community prisoners by using the A-PDA criminal execution prosecution system and the Judicial Access APP, and completed 420 community corrections inspection tasks. In view of the problems found, more than 10 oral correction opinions were put forward, and 1 procuratorial suggestion was issued. A-PDA criminal execution procuratorial system and judicial communication APP have become "two sharp tools" for our criminal execution procuratorial department to handle cases efficiently. This "wisdom+supervision" model provides us with strong information technology support to actively play the legal supervision function of procuratorial organs and improve the intelligence and specialization level of social governance.

Isn’t it incredible that gutter oil can not only be refined into biodiesel, but also become aviation kerosene to "fly" to the sky?

On September 18th, in Shenze Economic Development Zone, Hebei Province, the reporter walked into the product testing room of Hebei Huide Renewable Resources Co., Ltd., and Wang Meng, the technical director of the company, was sampling new products in front of the chlorine meter. Looking at the clear and translucent liquid in the glass dish, Wang Meng told the reporter, "This is the bio-aviation kerosene extracted from waste oil, which is colorless and tasteless."

This enterprise is well-known in the field of bioenergy. "We are the largest biodiesel producer in the province. Biodiesel is all refined from waste oil, with an annual output of 120,000 tons, and all products are exported to EU countries." Guo Jihui, the chairman of the company, said that at present, their production process of refining bio-aviation kerosene has completed the pilot test and has the conditions for large-scale production.

As early as the beginning of the factory in 2012, Huide Company aimed at the systematic research and technology development of waste oil resource utilization.

Shenze oil industry came into being with the development of daily chemical industry. As one of Hebei waste oil distribution centers, Shenze can collect more than 1 million tons of raw materials such as waste cooking oil and kitchen waste oil all over the country every year.

Relying on the foundation of local oil industry, Huide Company started with the extraction of epoxy fatty acid methyl ester from waste oil, and went through the process of technological innovation and equipment renewal, from providing bioplasticizers for manufacturers of disposable nontoxic PVC gloves and children’s toys to developing and producing bio-energy products such as biodiesel.

This is a green transformation. Along the way, Guo Jihui was deeply touched by the hardships of breaking through. "Every update link is like breaking through the customs, and every customs is a narrow escape."

"For the production of biodiesel, the waste oil should be heated to the evaporation point first, then condensed and recycled, and then the different components in the oil can be separated." Guo Jihui introduced that at the beginning, they invested more than 4 million yuan to build a new traditional tower distillation production line. After half a year of trial production, it was found that the separation efficiency was poor and the purity of refined fatty acid methyl ester could not meet the requirements.

In Guo Jihui’s view, the production of good products depends on innovation, and innovation cannot be afraid of investment. So, they scraped together nearly 6 million yuan, reluctantly dismantled the tower distillation production line and bought short-range molecular distillation equipment specially used for separation and purification of high-boiling mixtures. By updating the equipment, improving the process, and after repeated tests, Huide’s biodiesel production line finally reached its production capacity successfully.

The breakthrough from "0" to "1" is only the first step for this enterprise to rush to a new track.

Follow Wang Meng into the production workshop and see that the newly collected waste oil is being injected into a large tank, which is about to be pre-treated.

"In the pretreatment stage, we adopted a self-developed enzymatic process. The waste oil can be purified by biological enzyme catalysis, and high-purity fatty acid methyl ester and glycerol can be separated." Wang Meng introduced that with this process, the yield of biodiesel and glycerol can reach 90%, and energy consumption can be reduced by more than 3%.

With the breakthrough of key core technologies, Huide Company has successfully developed a new track for bioenergy industry. In 2022, the company’s annual biodiesel production capacity exceeded 120,000 tons, with an annual output value of 970 million yuan. "At present, the project with an annual output of 400,000 tons of bio-aviation kerosene is about to start construction." Guo jihui introduced.

What makes them even more happy is that the bioenergy industry chain here is accelerating.

In the past two years, Shenze County has seized the opportunity to build a strong new energy province, vigorously cultivated the development of bioenergy industry by gathering high-tech enterprises, improving infrastructure and expanding application scenarios, and has initially formed a whole industrial chain covering the collection and storage of waste oils and fats and the production of industrial-grade mixed oil, biodiesel, bio-aviation kerosene and other products. Up to now, there are 17 bioenergy enterprises in the county, and seven bioenergy projects with a total investment of 3 billion yuan are being accelerated. In the future, the annual production capacity of biodiesel and bio-aviation kerosene in the county will reach 400,000 tons and 700,000 tons respectively.

"Not long ago, Shijiazhuang was selected as a national pilot for the promotion and application of biodiesel, and the application scenarios became more and more abundant. Many foreign companies have come to us to discuss business." Guo Jihui is full of expectations for the future. "With the accelerated gathering of bioenergy enterprises, the industrial chain, supply chain and upstream and downstream regional cooperation in innovation chain will become closer and closer, and the competitive advantage of our products will become more obvious."

Xiaoai students have activated about 100 million devices, woke up 8 billion times, and lived 34 million in September. Xiaomi IoT has connected 132 million devices (excluding mobile phones and laptops)-this is the latest "connection" report card given by Lei Jun at this year’s Xiaomi AIoT conference.

IoT business is an important part of Xiaomi Valuation (Tencent multiplied by Apple’s market value) ridiculed by Lei Jun on the eve of listing. During the roadshow of Xiaomi’s listing, many investors generally believed that Xiaomi’s hardware should be benchmarked against Apple, and its software should be benchmarked against Tencent, so as to calculate the value of Xiaomi. IoT not only has a lot of diversion hardware on the Xiaomi ecological chain, but also relies on this foundation for Internet services and software with strong liquidity.

However, just as there is a huge gap between monthly activity and connected devices in the published data, how to keep users’ retention and activity has always been a problem discussed by people in the industry. Fan Dian, general manager of Xiaomi IoT platform department, is no exception. Although no relevant data is given, he said in an interview with Geek Park that in the future, AI and other ways will be used to maintain user activity.

"Xiaomi also needs enough equipment activation to reduce the unit R&D cost. An analyst who did not want to be named also said that active users have another meaning for Xiaomi. Obviously, people are curious about what the next step of Xiaomi IoT will be.

Expanding the service map is the first answer given by Xiaomi. At the AIoT Developer Conference, Xiaomi announced that it will cooperate with a "mysterious" guest-IKEA from December, and all the intelligent lighting products of IKEA will be connected to the IoT platform. In the future, it will be possible to control the intelligent lighting products of IKEA through Mijia’s App and Xiao Ai’s classmates.

Not only IKEA, Xiaomi also announced that it has reached a cooperation with All Seasons Hotel, and moved the scenes such as small love speakers and intelligent lighting to the upcoming All Seasons Hotel (Shanghai Hongqiao Center Store). In addition, there is a partner who can infiltrate users’ lives from the decoration. Love space.

At this point, Xiaomi’s service targets are not only the previous intelligent hardware enterprises, intelligent hardware solutions, traditional home appliance manufacturers, voice AI platforms, but also hotels, apartments and real estate.

The importance attached to the high-frequency scene of intelligent lighting was demonstrated by Xiaomi at the first IoT Developers Conference in 2017. At that time, as a strategic partner of Xiaomi, Philips Lighting proposed that by 2020, all new lighting products would be embedded with IoT technology to achieve "interconnection".

According to statistics, in a typical user’s home, there are 17 switches on average, and a typical user performs 25,000 operations on turning on and off the lights in a year. Whether it is Philips Lighting or IKEA, intelligent lighting, as the first cooperative product, is a good decision to cultivate user stickiness.

However, analysts’ views are slightly different. An analyst who was present believed that Xiaomi cooperated with these platforms because "AI and smart home are the trends. If we only make exquisite life cost-effective products, it is actually difficult for Xiaomi and Netease YEATION to open the gap. What Xiaomi is doing now is trying to empower traditional products intelligently, which will be more cost-effective at the same price or slightly more expensive. 」

After the deployment in the past few years, Xiaomi’s smart home has achieved "a little" results. So far, Xiaomi IoT has supported 2,000 devices, covering more than 200 countries, and 132 million smart devices have been activated (excluding mobile phones and laptops).

"In the future, Xiaomi may have to think about how to connect other friendly products to his own platform as much as possible, so as to control more devices through Xiaoai students, which can promote Xiaoai students faster and more widely, but this seems a bit difficult. Some analysts have raised their concerns about the future of Xiaomi.

However, Lei Jun doesn’t seem worried. He understood the truth of "making many friends and making few enemies" a long time ago.

"Xiaomi promotes the progress of IoT equipment, on the other hand, it has also caused some misunderstandings to the industry. Is it true that I can’t connect to Xiaomi’s IoT system without joining the Xiaomi ecological chain? I repeat, no. At the meeting, Lei Jun said, "Xiaomi’s determination to open up has not changed. I hope everyone can understand this. 」

As early as 2014, Xiaomi established an ecological chain department focusing on the incubation and cultivation of intelligent hardware, and established an ecosystem composed of more than 220 companies through investment and incubation, of which more than 100 companies focused on intelligent hardware and consumer products. Last year, Lei Jun officially announced that it would open IoT capabilities to all developers and serve more third parties. This year, Lei Jun once again stressed that as long as developers access Xiaomi’s ecological agreements and specifications, they can be connected with Xiaomi.

Lei Jun said that in the next 5-10 years, AIoT will be the core strategy of Xiaomi in the future. As the name implies, Wang Peng, senior product manager of Xiaomi IoT, proposed two ways to empower future AIoT developers. The first way is AI voice empowerment, and the second way is the Internet of Everything. The most practical example is the Zigbee protocol used in smart lighting cooperation with IKEA, which will also be open to all developers next year.　 　

Some research reports pointed out that Xiaomi has now accessed hundreds of millions of intelligent hardware devices, and the entire consumer Internet of Things has begun to take shape. Other hardware devices must access Xiaomi’s IoT platform if they want to interconnect with these hundreds of millions of devices. At the same time, the use of Xiaomi platform by developers can avoid high R&D costs, greatly reduce the threshold of hardware entrepreneurship, and at the same time, there are various support such as sales channels, which is a win-win cooperation.

The research report also predicts that in the future, the IoT platform will no longer be exclusive to Xiaomi and eco-chain enterprises, but will be a huge development platform, and Xiaomi will get a lot of service fees and a lot of data.

Regardless of whether the future development direction of MIoT (Xiaomi IoT) will develop in the secondary direction, the revenue performance of IoT is indeed getting brighter and brighter. According to Xiaomi’s financial report for the third quarter of fiscal year 2018, IoT and consumer goods business contributed 10.8 billion yuan to Xiaomi, up 89.8% year-on-year. The total revenue of the business in the first three quarters of 2018 reached 28.9 billion yuan, which exceeded the total revenue of IoT and consumer goods in the whole year of last year of 23.45 billion yuan.

132 million is a number mentioned many times at the meeting. This is a smart device that Xiaomi IoT has been activated so far, which means that Xiaomi IoT has become the world’s largest consumer-grade IoT platform. In the development of IoT, the privacy policies of various countries and regions are a challenge that cannot be underestimated in front of various developers.

The EU General Data Protection Act (GDPR), which came into effect on May 25th this year, is known as the strictest user data protection act in the history of the EU. According to the provisions of GDPR, enterprises must explain to users in a way that users can understand and accept before collecting personal information, and give users the right to withdraw the license agreement at any time. Companies that violate the regulations may face a penalty of up to 20 million euros.

Xiaomi’s experience will be a valuable asset for reference. As early as 2014, Xiaomi set up the Privacy Committee, and cooperated with TRUSTe (now renamed TrustArc) in California, USA, the world’s largest privacy authentication scheme provider, to carry out privacy protection related business. By 2016, Xiaomi has obtained the privacy mark of TRUSTe.

According to Liu Kai, senior product manager of Xiaomi IoT, MIoT’s current privacy policy is configured in accordance with the highest standard GDPR, and at the same time, corresponding policy adjustments are made according to local conditions. For eco-chain partners, MIoT launched a one-stop auditing system and product privacy mechanism tools. For example, the latter provided a standardized interface to help developers realize the demand of "user withdrawal agreement".

Privacy and security are twin brothers. With Google, Apple and other technology companies, and domestic home appliance giants have seized the market in the IoT field, IoT security issues are also coming to the fore. This year, Amazon Echo broke a news story. Echo recorded a conversation between a couple living in Oregon and sent it to contacts in the address book. As Xiaomi IoT Liu Daokuan said, "IoT security is a big deal when it happens. 」　

Before "AI+IoT" became Xiaomi’s new growth engine, Liu Daokuan said that Xiaomi should first make MIoT safe. Xiaomi has a relatively complete security infrastructure and confident security protocols (Wi-Fi, BLE, Zigbee, NFC security protocols), and these successful experiences will be solidified in the form of SDK and provided to developers.

The Internet of Everything is a huge territory. Although we can’t predict the end of the arrival, fortunately, some people have started to take the lead.

The following is a record of Lei Jun’s speech:

Lei Jun: Good morning, ladies and gentlemen! The popularity of our Xiaomi developer conference is far beyond imagination. Just now, I believed that all the people were jammed on the way, and they should have felt the heat of the conference. When my colleague introduced me yesterday, he said that today there are not only many developers, but also Xiaomi’s very close partners. There are also many managers’ funds of investment companies and analysts in the securities industry. I said, why are there some analysts in the securities industry? They said that Xiaomi was listed, right? In fact, it shows that everyone is very, very concerned about IoT.

IoT, the whole industry has been doing it for more than 20 years. It is not a new concept. It has been done for so many years, and it has not made a breakthrough until the last five or six years. Why? In fact, it is very simple. The IoT for more than 20 years is based on PC. When Xiaomi started to do IoT, what was Xiaomi’s thinking? When we started to do IoT, we wanted to connect all devices with mobile phones as the core, so we stood at the forefront of this era as soon as we came up.

So when we see today, why is the IoT industry developing so fast today, much faster than before? I feel grateful to this great era, that is, the mobile Internet. After we made mobile phones, when we wanted to connect all the devices, we even thought about whether we could connect with TV well. The mobile phone becomes the remote control of the TV, and the TV becomes the display of the mobile phone. How can we seamlessly connect all the devices together? This is also the reason why most Xiaomi mobile phones are equipped with infrared remote control. So, that’s our idea.

When you have a preliminary idea, is IoT done? We still encountered many difficulties. Then, we even considered whether we can use the router as a device, because the router is a device that is turned on 24 hours a day at home, so we think of the router as a home server.

I remember that we made intelligent routers very early, in fact, in order to solve the interconnection problem of IoT. When we finish all this, will things be solved? Still not. In 2014, we set up a special department to make IoT connection module, embedded system, cloud service system and control center. When we provided the whole solution, this is a photo when we released it in 2014. At that time, we proposed to provide IoT intelligent module chips to our partners at the material price. I remember that at the beginning, a Wi-Fi connection module cost more than 60 RMB, and we soon got more than a dozen modules of IoT, which effectively promoted the intelligence of the equipment.

Of course, it is not enough to do this step. In 2014, we set up the Ecological Chain Department, which specializes in incubating and cultivating intelligent hardware. We have trained nearly 100 enterprises in the past time. Of course, today, I am very happy that many Xiaomi eco-chain enterprises have grown up or even listed, such as Huami and Yunmi this year, and they have successfully listed overseas.

Therefore, after so many years of deployment, Xiaomi’s IoT has made a little progress. Let’s take a look. Up to now, 2,000 devices have been held. By the end of the third quarter, the number of activated smart device connections was 132 million (excluding mobile phones and laptops). Maybe many people don’t have much idea about 132 million units, which have already ranked first in the world among consumer IoT devices. That is to say, whether it is Google or Apple, or the domestic appliance giants, the number of devices they have activated to connect to the Internet is actually a little far from Xiaomi.

What do I think Xiaomi has done on IoT at this moment to achieve these achievements? The most important thing is that Xiaomi attaches great importance to its partners, so we set up an ecological chain department five years ago to incubate intelligent hardware startups, and we have spent a lot of money to get to today step by step in this field. So I think today’s achievements are hard-won, and we will attach great importance to the alliance with our partners as in the past.

When IoT developed into this era, two years ago, I felt that artificial intelligence had made a huge breakthrough. After AI empowered IoT, the IoT industry showed a faster growth trend. I think there are many places where AI can empower IoT. Intelligent voice assistant is only a small link, but this link has brought a huge revolution to IoT equipment. What is the most obvious thing? It’s AI’s smart speaker.

Two years ago, Xiaomi regarded AI smart speakers as a key breakthrough in strategic commanding heights. Since its release in July last year, Xiaoai smart speakers have also ranked among the best in this field. I believe that most of you here should have used Xiaoai smart speakers. Why do I ask this question? Everyone says that there are at least forty or fifty kinds of smart speakers on the market, and many people think this thing is useless. Before July last year, we had a big internal debate. Everyone felt that the technology of artificial intelligence was not so mature. After the release of this product, perhaps the reputation was not so good. But to be honest, the response after the release far exceeded my imagination. Demand has been in short supply until May and June this year. Therefore, the whole smart speaker is well received than expected.

I communicated with Xiao Ai’s R&D department, and they even told me who is the most popular with Xiao Ai’s smart speakers? He is an empty nester and has no children at home. It is quite interesting to chat with Xiao Ai’s classmates. There is also a group of children who love to use speakers as toys at home. Of course, it is very important that the small love speaker can connect the smart devices of various IoT.

What is my own idea? I believe that control technology such as AI+IoT will be embedded in every device in the future. There may not be a special device called smart speaker, or smart speaker will become a very small device. This technology is embedded in every device. For example, I don’t need this page flipper. I just need to turn the page, and it will turn the page. I think in three to five years, every smart device may have the control module of AIoT, which will make the whole interaction very interesting. Our product department has also done a lot to embed AIoT technology into the equipment. For example, a small alarm clock released a few days ago actually has the intelligent technology of Xiao Ai’s classmates. In this case, the whole application will be wider and wider. I imagine that in a few years, the cost will be so cheap that every device will be easily connected to AIoT technology.

A month ago, I released Xiaoai’s Bluetooth speaker, which is very small, 49 yuan. Although it is small, the sound quality is actually excellent. A month ago, at the Xiaomi MIX3 conference, we released this little love Bluetooth speaker. I believe that this very easy-to-use voice interactive assistant will be embedded in every smart device in the future. Of course, I won’t talk about how AI empowers big data and other aspects. I at least think that the technology of AI smart speakers will be applied to the interaction of the whole smart device. We have embedded into these devices, which is Xiaomi Xiaoai’s smart alarm clock. More than 100 yuan can solve many problems.

Let’s take a look at what achievements Xiaomi’s Xiaoai classmate’s intelligent voice assistant has made in just over a year. A total of 100 million devices have been activated, because Xiao Ai is not only on smart speakers, but also on mobile phones, televisions and children’s story machine, and 100 million devices have been activated. Accumulated 8 billion awakens, I think this figure is relatively bullish, and the monthly activity has reached the scale of 34 million at the end of September. Therefore, everyone knows an intelligent system like Xiao Ai’s. In fact, the more you use it, the more intelligent it will become. They used to joke with me that there is as much intelligence as there are people. In fact, the more you use it, the smarter it becomes. Therefore, I believe that with such a large number of users, Xiaoai’s intelligence will become higher and higher.

So, what do I want to communicate with you today? But AI+IoT is the core strategy of Xiaomi. We have the earliest layout and the largest investment in this field, and I think our determination is also the greatest. Therefore, after five or six years of layout and five or six years of growth, we have developed to today’s scale. Looking at the next 5-10 years at this moment, it will always be the core strategy of Xiaomi.

And when it comes to core strategy, what advantages does Xiaomi have compared with other peers? It is the huge intelligent hardware ecological chain and the entire ecological environment that Xiaomi has formed. Moreover, we have an online Xiaomi Mall and a wired Xiaomi Home, and we also have a good marketing channel for IoT equipment. More importantly, we have a lot of users who highly recognize Xiaomi’s products, which will greatly improve the user experience and make the perception stronger and stronger after the whole IoT is empowered.

So, speaking of this, the most important thing for me today is to introduce the open ecology of Xiaomi’s AIoT. Throughout the open ecology, there are two Xiaomi and the relevant department heads at our conference to introduce the open ecology of AIoT. One is our IoT platform department, and the other is the head of Xiaomi’s artificial intelligence voice service department, which will give you a detailed introduction to the open ecology of AIoT.

What am I going to tell you? It is the determination of Xiaomi to cooperate. Everything is connected with wisdom. If we want to connect everything, I think the most important thing is the sincerity of cooperation. In the past five or six years, Xiaomi has come to this day because of cooperation and opening up. At today’s stage, the whole giant is extremely optimistic about the AIoT industry, and the competition is becoming more and more fierce. I think Xiaomi is more open than before.

In order to promote the opening up, we set up the Xiaomi Eco-chain Department, so that on the one hand, we promoted the progress of IoT equipment, on the other hand, it also caused some misunderstandings to the industry, saying that I can’t connect to Xiaomi’s IoT system without joining the Xiaomi Eco-chain? I think this is a big misunderstanding. We set up the Eco-chain Department to promote this matter, so that more people can effectively interconnect the equipment together. Therefore, as long as you access these protocols and specifications of Xiaomi, you can connect with Xiaomi’s equipment. Xiaomi’s investment is only to promote and strengthen this cooperation more effectively. This is what I want to explain to you today. Xiaomi’s determination to open up has not changed. I hope everyone can understand this.

Later, we will have two special reports to introduce our whole open ecology and open agreement. Thank you again for coming to our Xiaomi Developer Conference today. Thank you!

Although the inventor of the dual-clutch gearbox is not Volkswagen, there is no doubt that the role of Germans in popularizing it. With the increasing sales of related models, some problems have also been exposed. On the other hand, most countries and regions, including China, have gradually upgraded their emission standards. For this reason, Volkswagen is constantly upgrading its dual-clutch gearbox. Today, let’s take a look at the latest "upgrade from 0 to 1".

○ Until today, the industry has not yet reached a conclusion about who invented the dual-clutch gearbox. Germans are proud of being the first to apply for patents, while French are proud of small-scale production;

○ Specific to the Volkswagen brand, the golf R32 in 2002 is the beginning of our familiar story;

○ Volkswagen Group took the lead in developing and producing a wet dual-clutch gearbox, and then introduced a dry dual-clutch gearbox to meet the needs of low-grade models.

Before launching the technical upgrade, let’s briefly review the current use of the dual-clutch gearbox of Volkswagen Group. In short, according to the horizontal and vertical layout of the powertrain, they named the dual-clutch gearbox DQ and DL respectively. Secondly, according to the tolerable torque, it is subdivided into different models.

Some dual clutch gearbox models of Volkswagen GroupWell-known dry/wet gears are equipped with DQ200 dry 7-speed golf 6DQ250 wet 6-speed DQ380 wet 7-speed DQ381 wet 7-speed DQ500 wet 7-speed Audi RS3DQ400e wet 6-speed GTEDL382 wet 7-speed DL501 wet 7-speed Volkswagen DL800 wet 7-speed, Lamborghini Huracán

The "upgrade from 0 to 1" we are going to talk about today is DQ380 and DQ381. Although both of them have been on the market for some time, their development concept will be gradually extended to other products in the DQ family, so they can be regarded as the embryonic form of the development of Volkswagen dual-clutch gearbox technology in the future.

The oil pressure of DQ380 gearbox is based on the mechanical gearbox oil pump, and the engine crankshaft drives the gearbox oil pump. After the engine stopped working, the oil pump lost power. When the driver needs to start again, the traditional mechanical oil pump needs to build up the pressure again, and there will be some delay.

DQ381 adds an electric motor oil pump, and the power comes from a 12V battery pack, so that there is still a power source after the engine is turned off, and the response speed of the vehicle will be faster.

In terms of oil, considering the factors such as reducing friction and emission, DQ381 gearbox oil is thinner than DQ380 gearbox oil, and its formula is slightly adjusted considering the requirements of heat dissipation, lubrication and force transmission.

Written in the back:

The congestion environment in the city has gradually shrunk the sales of manual gearboxes, and the corresponding market share of AT, CVT and DCT has greatly increased compared with 10 years ago. Among them, DCT, the dual clutch gearbox, is favored by manufacturers and consumers because of its relatively low manufacturing cost and compact structure. It takes time for technology to develop and mature. Volkswagen’s dual-clutch gearbox has problems in popularization, and it is also improved in step-by-step upgrade iteration.
