5g, big data, Internet of things and artificial intelligence are widely used – cities become more “smart”

The city novel coronavirus pneumonia is the “cloud storming” Office of the enterprise employees and the brainstorming in video conferencing. When residents enter the district and visit supermarkets, they produce health codes. Doctors use 5G and artificial intelligence for remote consultation and treatment. Since the outbreak of the new crown pneumonia, our lives have made many new changes, and our city is becoming more intelligent.

Today, new technologies such as 5g, big data, Internet of things and artificial intelligence are developing continuously and are widely used in the construction of new smart cities in China, giving birth to a new model of digital, networked and intelligent public services and a new concept of urban governance, which brings a lot of convenience to people’s production and life. In the future, how can we better promote the construction of a new smart city?

Health code and information platform are of great use

During the epidemic, novel coronavirus pneumonia information service program was developed on the platform of “elong rock” in Longyan, Fujian Province, and a number of related services were launched to enable the public to quickly query information, online voluntary consultation, and timely report the epidemic situation. The problems reflected by the public are uniformly summarized on the 12345 platform. If the platform can reply, it will give a reply immediately. If the professional problems cannot be answered, it will be transferred to the relevant departments for treatment in time.

Ms. Yang, who lives in Daxing, Beijing, returned to the community after work and is showing the Beijing health code to the property security personnel. After confirming “no abnormality”, she was allowed to enter. “Now I have to show the health code four or five times a day, which is very convenient to use and conducive to epidemic prevention and control,” she said.

Wuhan, which had been closed for 76 days, reopened the channel from Wuhan to Hubei. Early that morning, many passengers came to Wuhan railway station. They wore masks and took the Hubei health code “green code” and took high-speed rail to all parts of the country. For them, “green code” means “pass” to resume work. Since this year, health codes, epidemic prevention maps, information platforms, intelligent temperature measurement, screening and early warning systems have become popular in many cities and have become a powerful means to combat the epidemic.

Where does the "wisdom" of the city come from?

Wang Yukai, a professor of the Central Party School (National Academy of administration) and a member of the national informatization expert advisory committee, said that China’s epidemic prevention and control has achieved major strategic results, which is closely related to China’s promotion of smart city construction in recent years. Since the outbreak of the epidemic, local governments have timely released information to the society through the government information platform, released the local epidemic situation, let the public know the situation in time, and improved the public’s prevention ability.

Wang Yukai said that in the construction of smart city, we have established a strong data base, which is of great use during the epidemic. The government has a lot of public data, such as population database, geographic information database, etc; Telecom operators master a large amount of data through mobile phone real name system; Internet enterprises also have a large amount of data by providing market services and social services. These different types of data provide support for epidemic traceability, transmission chain tracking, group prevention and group control.

“Without the construction of a smart city, it would be impossible for us to hold so many video conferences today, for tens of millions of enterprises to work online, and for hundreds of millions of students to take classes online.” Gao Xinmin, member of the national informatization expert advisory committee, believes that the information sharing and service platform created by the government played an important role during the epidemic, Internet companies have provided a large number of intelligent services around the normal operation of the city and the living needs of the people, increased the flexibility of economic and social operation and improved the impact resistance of the city.

At present, what is the current situation of smart city construction in China? Some studies say that China’s smart city construction has generally experienced four stages: the first stage is the exploration and practice period. From the concept of “smart city” at the end of 2008 to August 2014, all departments and localities promote the smart city construction according to their own understanding, which is relatively scattered and disorderly; The second stage is the normative adjustment period. From August 2014 to December 2015, the “inter ministerial coordination working group for promoting the healthy development of smart cities” was established at the national level. Instead of fighting alone, all departments began to cooperate and guide the construction of local smart cities; The third stage is the strategic breakthrough period. From December 2015 to December 2017, the concept of a new smart city was put forward and upgraded to a national strategy, focusing on promoting the integration and sharing of government information systems and breaking information islands and data segmentation; The fourth stage is the period of all-round development. Since the 19th National Congress of the Communist Party of China, the construction of new smart cities has accelerated, and the construction achievements have gradually extended to districts, counties and rural areas.

Experts said that at present, China’s smart city construction has achieved positive results. According to statistics, all cities above the sub provincial level and more than 89% of cities at the prefecture level and above have proposed to build smart cities. While releasing the overall action plan for the implementation of smart cities, provinces and cities continue to promote the practice in specific fields such as “smart education”, “smart medical treatment” and “smart transportation”, and explore the key points and development paths suitable for the construction of local smart cities. After years of construction and innovative development, a number of innovative applications such as “urban brain” and Internet hospitals have emerged, providing a model for the construction of global smart cities in some fields.

Data islands and fragmentation still exist

Experts said that on the whole, China’s new smart city construction has achieved positive results, but it also faces problems such as weak top-level design, insufficient urban data integration and governance linkage, unbalanced urban-rural and regional development, and the development ecology of smart city has not been formed, which need to be improved.

Where does the “wisdom” of the city come from? From the data.

The essence of the new smart city is to use the new generation of information technology to reshape and rebuild the city, and use the attributes of smooth flow and open sharing of data resources to force the unreasonable management system, governance structure, service mode and industrial layout of the city to become more reasonable, optimized, transparent and efficient. At present, in the process of building smart cities in China, data islands and fragmentation still exist.

“In the process of dealing with the epidemic, there are phenomena that data cannot be shared and departments work in their own ways in some places, and some business systems we build lack collaborative functions. These problems expose that there are still many shortcomings in the construction of China’s new smart city.” Wang Yukai said how to make further efforts in these aspects to make smart cities better serve the people, Truly focusing on the people is the direction of our future efforts.

“With the development of smart city today, more and more attention is paid to the role of data and data value chain.” Gao Xinmin said that the essence of “urban brain” is to gather all aspects of urban data and generate intelligent decision-making through artificial intelligence analysis and calculation. At present, the biggest bottleneck in the construction of “urban brain” lies in the data aggregation link. The standards and interfaces of multi-source and cross departmental data in different information systems are different, and the data flow mechanism is not clear and the process is not smooth.

Gao Xinmin suggested that to realize data sharing, first of all, there should be a technical framework to realize data interoperability, and on this basis, there should be rules and system design. Under the principle of respecting security, sovereignty and demand orientation, once there is a demand, it can quickly build a data resource pool to support specific applications in time and at low cost to maximize the value of data.

Shao Guoan, deputy director of informatization collaborative innovation professional committee of China informatization promotion alliance, said that data standardization must be done in the process of building a new smart city. The mobile phone should name the ID number, cell phone number, name, home address and other key sensitive data. It should store encrypted data, and location data and other data can be partly opened and managed according to the needs.

In the future, we should pay equal attention to technology and system innovation

Recently, digital China Holdings Co., Ltd. signed the Weihai smart city project. “We will work hard in Weihai City.” Guo Zhengli, chief operating officer of Shenzhou holdings, said that it is planned to build a comprehensive management center for the operation of Weihai smart city and Weihai “urban brain” by taking “number” and “intelligence” as the core and making full use of emerging technologies such as the Internet of things, big data and artificial intelligence in three years to promote transportation, medical treatment, culture, tourism Intelligent transformation in education and other fields.

“Better City, better life”, and beauty is inseparable from wisdom.

Some people once looked forward to the future life: driverless cars move forward smoothly under the guidance of intelligent transportation system; After placing an order online, UAVs and logistics robots will be sent to express in time; Before getting off work, the smart home system will turn on the air conditioner and air purifier in advance to prepare a suitable and fresh home environment… Experts believe that in the future, living in a new smart city, these scenes will become commonplace.

Zhang Yansheng, chief researcher of China International Economic Exchange Center, believes that in the future, smart city construction should be deeply integrated with the development of productive services, living services and public services, and gather global talents; Deeply integrate with digital technology, digital formats and digital innovation to promote the intelligent, automatic and networked development of the real economy. At the same time, we should pay attention to the international situation, turn danger into safety and turn danger into opportunity in the great change; We should be determined to build and improve the development ecology with independent intellectual property rights, brands and modern industrial system.

“The driving force of smart city development largely comes from the needs of the new generation,” said Zhang Yansheng, from “millennials” to “generation Z” and then to“ α Generation “, their different needs for a better life will promote the construction of smart city to a new level; At the same time, they will also become a new force to promote the high-quality development of smart cities. At the same time, we cannot ignore the vulnerable groups that are easily marginalized in the construction of smart cities. We should respond to their concerns in time and protect their rights and equal opportunities for development.

Experts suggest that in the long run, to promote the development of China’s new smart city, we should pay equal attention to technology and system innovation. Strengthen the top-level design of smart city and issue the overall planning or construction guidance of new smart city at the national level as soon as possible; Improve the new digital infrastructure, vigorously develop smart pipe network and smart water, promote the application of smart lamp posts and smart well covers, promote the intellectualization of municipal facilities, accelerate the establishment of urban component Internet of things perception system, and improve the level of urban digitization.

At the same time, we will promote the fairness and inclusiveness of public services, establish a public service information system of cross sectoral and cross regional business collaboration, co construction and sharing, and explore innovative service models for education, employment, social security, elderly care, medical care and culture; Deepen the application of urban data fusion and build an efficient and intelligent urban hub and transparent government; Optimize the new smart city ecology and release the vitality of urban data elements through system and mechanism innovation.
