  5G, artificial intelligence, digital health, satellite applications... At the 2nd Digital China Construction Summit, which opened yesterday, many high-tech topics were discussed. Academicians of the Chinese Academy of Engineering, representatives of operators, and Internet celebrities attended the main forum of the summit. They put forward unique views and insights on the development of digital economy and the construction of digital China in their respective fields.

  The Internet of Things brings convenience to life

  Zhang Jun, President of Beijing Institute of Technology and academician of the Chinese Academy of Engineering, mentioned in his speech that smart society is an important trend in future development. Since the development of human society, intelligence has become a new factor of production, and the intelligence of technology and society has given birth to a smart society.

Taking his own example, Zhang Jun said that in the current transportation society, people are mainly affected by transportation methods. "People should actively adapt to specific flights, high-speed rails, and taxis." If there is an Internet of Intelligence, transportation methods will adapt to people, and people will Mastering greater autonomy will bring more convenience to people's lives. For example, if you come from Beijing to Fuzhou for a meeting, you can connect to the Internet through a mobile APP, and send out the needs of 30 people here to go to Fuzhou, and then you can "fly" together to come here. Like this, there can also be customized high-speed trains, shared long-distance buses, etc. This is the change of autonomous transportation to life.

  5G accelerates the Internet of Everything

   For communication technology, 2G solves the voice communication between people, 3G solves the communication of information and text, 4G solves the problem of image transmission, and the 5G era accelerates the interconnection of everything.

   Wang Xiaochu, Secretary of the Party Group and Chairman of China Unicom Network Communications Co., Ltd., introduced that 5G technology has low latency, fast speed, and high number of connections, creating a good environment for the Internet of Everything. The Internet of Everything has produced a flood of data, which has led to an explosive growth of data. He introduced that the flood of data itself is not the purpose. Only by adding algorithms and computing power to artificial intelligence can the data really be used by me. He said: "The 5G era is the interconnection of all things. Changes in data flow will affect logistics, talent flow and capital flow, and will accelerate the efficiency of the entire society."

  Communication operators are still the main force in the construction of digital China. At present, the three major operators are transforming the existing network to make the network state more high-speed and secure, while reducing tariffs. China Unicom will deploy 5G networks in seven urban areas of Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Hangzhou and Xiong'an, and can also build customized 5G networks for specific industries.

   AI will be the “main course”

   In recent years, the development of the artificial intelligence industry has ushered in an explosion, and the entire industry has begun to re-understand the value of technological innovation. Robin Li, founder of Baidu, said that for the digital economy, the Internet is only the "appetizer", and artificial intelligence is the "main dish". Artificial intelligence is the trinity of data, algorithms and computing power, and the coordinated development. Doing well in artificial intelligence requires more patience and longer investment.

   He said that in the future, no company can claim to have nothing to do with artificial intelligence. There is basically a consensus on this point. Therefore, every industry and every enterprise should consider how to use effective methods to enhance technological innovation capabilities and turn artificial intelligence into "its own dish". Otherwise, if you can't eat this "main dish", you may miss an era. In the process of intelligence in traditional industries, Baidu Cloud empowers the quality inspection of information appliances. Engineers use computer vision to make a machine that integrates software and hardware. The efficiency of a piece of equipment is equivalent to ten skilled workers, and its accuracy will be higher and the floor space will be greatly saved. Under the empowerment of Baidu Cloud, traditional industries can not only improve efficiency, but also liberate workers from heavy labor.

  Tencent has participated in the construction of "digital government" in Guangdong Province. With the help of Tencent Cloud technology, Guangdong Province has launched a WeChat mini-program "Guangdong Provincial Affairs" that integrates livelihood services for the common people. Among them, the government has unified planning of services between various departments, and has built a full-process integrated online service through Tencent Cloud's open cloud computing, artificial intelligence and other technical capabilities, bringing the people "government affairs at their fingertips" services. According to reports, the "Guangdong Provincial Affairs" applet has realized the handling of 607 high-frequency and convenient service items such as provident fund inquiry and transfer, medical insurance reimbursement, etc., and launched 53 kinds of personal electronic certificates such as ID cards, social security cards, marriage certificates, and disability certificates. The cumulative inquiries and transactions exceeded 130 million. Ma Huateng, chairman of Tencent's board of directors, said that last year Tencent also joined forces with the Fujian police to use facial recognition technology to help more than 1,000 families find long-lost relatives. "That's the warmth and strength that technology gives us," he said. (Li Ruyi)
