A few days ago, General Secretary Xi Jinping pointed out at the Hangzhou City Brain Operation Command Center that making cities smarter and smarter is the only way to promote the modernization of urban governance systems and governance capabilities, with broad prospects. The city brain is an important part of the smart city. With the wave of 5G construction, the city brain based on 5G will become more "smart and intelligent" in the future, which will further promote the development of smart cities.
What is the urban brain?
In layman's terms, this "brain" is to use advanced technologies such as artificial intelligence, big data, and the Internet of Things to build a back-end system for urban traffic governance, environmental protection, city refined management, regional economic management, etc., to open up different platforms and promote the city. Digital management.
What parts does the city brain include? Take Hangzhou as an example. It is not only the city brain operation command center, it also includes the “knowledge reserve” of 83.7 billion pieces of data of various departments and units in Hangzhou, and citizens’ smart phones, citizen cards, traffic lights, parking lots, parks, etc. Hospitals are all “tentacles” that the “brain” can directly reach. Through the connection between the “nerves” and the “capillaries” of the network, the “brain” needs to coordinate hundreds of millions of data every day.
Many of the city’s brains were originally intended to control congestion. “Digital control of congestion” solves complex traffic problems. For example, Hangzhou, without adding any other facilities, basically only uses data resources to make the entire city of Hangzhou fast. The traffic efficiency of vehicles on roads and elevated roads has increased by an average of 50%, which is equivalent to using the "urban brain" to build "one more road".
In addition, during the epidemic, Xiamen’s first online appointment purchase model for masks is also a manifestation of the city’s brain. Through online appointments, the number of masks can be allocated to various pharmacies in the city, so that citizens who make an appointment can buy them within a specified time period. This can prevent In the case of crowding, it can guarantee that the citizens can buy masks.
In addition, the city brain can also complete many convenient applications that are convenient for citizens. For example, “pay at most once” for medical treatment. After the treatment, you can either pay for one-time self-service in the hospital or use your mobile phone to pay at home; one more hour of travel: including “10 seconds to find vacancies” and “20 seconds to enter the park”. The four convenience services of "30-second hotel check-in" and "digital travel line".
Urban brain construction has become a boom
I found that not only Hangzhou, but also Beijing, Shanghai, Shenzhen, Xiong'an and other cities are building urban brains, and urban brains are gradually becoming a new infrastructure for future cities.
Not long ago, when General Secretary Xi Jinping visited Wuhan, he proposed to establish the consciousness of "full-cycle management". With the rapid flow of people, logistics, information, and capital in large cities and megacities, risks are also rapidly accumulating, erupting, and spreading. "Full-cycle management" must rely on intelligent means such as the urban brain.
The Xiongan New District under construction also plans to build a deep learning and self-optimized Xiongan Smart City Brain. Previously, Xiongan deployed a new generation of Internet of Things experimental network, smart municipal management and other new smart applications through China Telecom. At present, based on the new generation of Internet of Things, the new district management committee smart parking demonstration point, Aowei Road smart manhole cover, and smart street lamp demonstration The site has been fully completed and put into use.
After the outbreak of the new crown pneumonia epidemic, the Sichuan Meishan Public Security Bureau and China Telecom conducted a 5G+ drone business test, explored the smart path of urban governance, and greatly improved the efficiency of epidemic prevention.
Feng Songlin, a researcher at the Shanghai Institute for Advanced Study of the Chinese Academy of Sciences, said: "There are about 500 cities in the country that have proposed to be urban brains, covering almost all cities above the prefecture level." It seems like a boom. In this regard, some scholars believe that with the development of technology, the urban brain will bring comprehensive urban governance to a higher level.
5G empowers smart city development
Combining with the problems of refined urban governance exposed in a special period, smart cities are expected to become an important construction content of new infrastructure. Obviously, the urban brain, as an important part of a smart city, will become an effective tool for improving urban governance capabilities.
Recently, the Ministry of Industry and Information Technology stated that it will accelerate the progress of 5G network construction. It is expected that the number of 5G base stations nationwide will exceed 600,000 by the end of 2020. As the latest generation of wireless communication technology, 5G's ultra-high speed, ultra-low latency, and ultra-large connection characteristics have a huge impact on the construction of smart cities. The ubiquitous sensor network based on it realizes the intelligent connection of all things in a smart city, and the deep integration of human, machine, and things. At the same time, deep integration with a new generation of information technology represented by cloud computing, big data, artificial intelligence, and the Internet of Things. , By enabling 5G networks to flexibly configure network resources according to end application scenarios to meet the needs of smart cities for network differentiation, it will become an important capillary supporting urban development, which will bring revolutionary changes to urban management, and ultimately create a super-strong urban brain. Smart city empowerment.
"5G integrates artificial intelligence, big data analysis, cloud computing, and the Internet of Things, represented by a new generation of information technology, will comprehensively and profoundly change all aspects of urban production, life, and governance." Some market participants said that 5G networks uniquely satisfy wisdom. The ability of the city's multi-scenarios to differentiate the needs of the network is crucial to the construction of smart cities.
