At present, China has entered the "post-epidemic period", and social and economic development, enterprise operation and people's life are gradually returning to the daily state.However, during the epidemic period, the problems existing in urban construction were also exposed: the city security monitoring system was not perfect, the urban space planning was not reasonable, the response of major sudden public emergency management plan was not timely, and the data information of each city was isolated from each other.
For example, many communities have access control system, but in the outbreak period, access still rely on the "access card" or on the paper form registration information;Grassroots managers also cannot accurately grasp the flow of people in their jurisdiction, and they cannot better complete the work of epidemic prevention and control.
"Urban governance" is particularly important for smart cities.
Urban governance: the highlight of building a smart city
How to do "city governance" well?
First, we need to collect city data from various dimensions.Then, systems and platforms are established, and technical means are used to analyze data and draw conclusions, so as to help managers make more efficient and rational decisions.
Based on this, yiou sorted out 17 a-share enterprises in the domestic security video surveillance equipment, information software including public information security system, urban traffic information system and other fields.
In the two fields of security video surveillance and public information security, the main service objects were initially concentrated in the departments of public security and transportation.
Later, with the development of information technology, security video surveillance and public information security began to extend to the community, finance, education, medical and other fields, and the trend of "crossover" is still continuing.
It is worth mentioning that: security video surveillance, as the bottom support of the entire security system, mainly USES the camera to collect the image information in the monitoring area, and transmits it to the monitoring center in the form of video signals, so as to display the image content of the monitoring area and effectively complete the task of protecting the monitoring site.It is the core equipment in urban governance.
In the case of continuous integration of computer technology, coding and compression technology, network transmission technology, storage technology and other technologies with video surveillance, security video surveillance has experienced two leap-forward development.
Firstly, from the traditional analog monitoring to the digital monitoring, the security video images at this stage began to be stored digitally, and the resolution entered the era of "standard and clear".Secondly, the rise of the new generation of information technologies, such as big data, cloud computing and AI, makes the resolution of security video enter the high-definition era.
Transportation is the infrastructure of a city. Relevant government departments can make good urban transportation planning and governance policies by relying on the information reflected by urban transportation and urban railway transportation information system.Now, the national "new infrastructure" policy release, is to accelerate the network information digital development of urban traffic governance.
In general, security video surveillance equipment, public information security system, urban traffic information system and urban rail traffic information system, the four types of urban governance application layer, is to strengthen the smart city infrastructure construction solid backing.
To build a smart city, it is necessary to have the technological and industrial foundation
Urban governance promotes the construction of smart cities from the bottom, and drives the development of urban industries towards the direction of intelligence and informatization.Of course, in addition to the urban infrastructure construction involved in urban governance, AI, big data and other technologies also bring improvement to urban governance.
For example, in 2019, jiujiang city government cooperated with aliyun to build "artificial intelligence + urban brain" in jiujiang city. This project mainly carried out intelligent transformation in the fields of urban data infrastructure, urban livelihood services, urban governance and urban smart industry.
Aliyun supports jiujiang municipal government to promote the project of "artificial intelligence + urban brain", and while building an open innovation platform, it also USES its data intelligence technology system to alleviate difficult problems in urban construction and improve the city's comprehensive governance capacity and public service level.By using cloud computing, mobile Internet, artificial intelligence, Internet of things and other technologies, jiujiang city has created smart tourism, industrial Internet, intelligent manufacturing and other new business CARDS.
In addition, aliyun also assists the government in monitoring major pollution sources and other environmental factors in the city, in an effort to boost the green economy.
Besides jiujiang city, many other cities have started to build smart cities.Beijing, shenzhen, fuzhou, chongqing and other cities began to build "smart cities" after the state officially launched the "national smart city pilot" policy in 2012.In addition, according to deloitte's super smart city report, there are more than 1,000 smart cities started or under construction in the world. In terms of the number of construction, China takes the first place with 500 pilot cities and has formed several large smart city clusters.
However, as cities build smart cities, we should also see some problems in building smart cities.For example, some cities do not have the technical and industrial conditions needed to build smart cities, which will lead to the government, enterprises and other participants in the construction to waste a lot of human, material and financial resources, energy is not used on the "blade", may also have an impact on residents' lives.
"China's smart city construction in recent years has not yet completed the process of blind men and elephants," said shan zhiguang, director of the informatization and industrial development department of the state information center.According to shan zhiguang, there are three core problems in the construction of smart city.Second, the lack of effective top-level design theory and method;Third, the lack of sustainable dynamic mechanism and long-term operation and development model.
Therefore, to promote the construction of a new smart city, it is necessary to have a clear strategic positioning and policy orientation, and formulate urban planning and implementation paths that match the development direction of the city itself.
Smart city construction is a systematic engineering project, which not only has a long construction cycle, but also requires city managers to consolidate urban governance and urban operation service quality all the time. Through the "management" ability of data, the information island between cities can be opened up and the core competitiveness of cities can be improved.
