Smart management makes municipal facilities safer, smart platforms make travel faster, and smart communities make life better... At present, many places are laying out new urban infrastructure construction based on digitization, networking and intelligence (hereinafter referred to as "new urban construction") to promote urban transformation and upgrading. Where is the "new urban construction"? How's it going? Recently, the reporter conducted an interview. Focus on urban safety, community construction, municipal services and other fields In the safe operation monitoring center of Hefei urban lifeline project in Anhui Province, the monitoring data of gas, water supply, bridges and other facilities are updated in real time on the screen. With the help of the four-color safety risk spatial distribution map of "red, orange, yellow and blue", the hidden danger points of the city's important infrastructure can be clearly identified. "For example, for gas, the intelligent monitor can analyze whether there is leakage in the pipe network and send out early warning in time, collecting hundreds of millions of data every day; for water supply, the application of pipe network leakage detection intelligent ball, and the leakage positioning accuracy within 25 kilometers can reach 2 meters..." Li Xuan, deputy director of the monitoring center, introduced that the system has been running for more than four years, and the cumulative prediction and early warning of gas pipe network leakage, excessive biogas concentration, water supply pipe network leakage There were more than 6000 sudden dangerous situations such as road collapse, the accident rate of underground pipe network in the city was reduced by 60%, and the risk investigation efficiency was improved by 70%. After years of high-speed and large-scale construction, the municipal, transportation, communication and other subsystems of the city are complex, and many potential risks have been accumulated. The problems such as aging of underground pipelines and unclear bottom number are prominent, and urban waterlogging and other accidents are frequent. It is urgent to update and transform and promote the construction of new urban infrastructure. According to the relevant person in charge of the Ministry of housing and urban rural development, the key tasks of "new urban construction" include comprehensively promoting the construction of the basic platform of urban information model and building the basic platform of smart city; Implement the construction of intelligent municipal infrastructure, upgrade and manage the municipal infrastructure such as water supply, heating and gas; Coordinate the development of smart cities and smart Internet connected vehicles to create a smart travel platform "Auto City Network"; Accelerate the construction of smart communities; Promote the coordinated development of intelligent construction and building industrialization; Promote the construction of urban operation management service platform, etc. In 2020, the Ministry of housing and urban rural development will carry out the first batch of "new urban construction" pilot projects in 16 cities such as Chongqing, Fuzhou and Jinan. At the same time, it also organized a series of special pilot projects such as the construction of urban information model basic platform, intelligent municipal administration and intelligent construction. Improve urban operation efficiency and make life more convenient, safe and comfortable More than 15.7 million urban components such as signal lights and fire hydrants, more than 86000 kilometers of underground pipelines and more than 3600 historical protection buildings... Relying on the basic platform of urban information model, Shanghai has "moved" these massive data to digital maps to realize visual and standardized sharing and interaction. Fuzhou, Fujian Province, used big data, Internet of things and other technologies to implement joint drainage, drainage and commissioning of water system, and conducted intelligent and accurate regulation and control of more than 1000 reservoirs, lakes, pools, rivers, gates and stations in the urban area. The emergency disposal efficiency of drainage and flood prevention in flood season was improved by 50%, and the regulation and storage efficiency of reservoirs, lakes and rivers was improved by 30%, which improved the safety and toughness of the city. "Through the digital, networked and intelligent renewal and transformation of urban infrastructure, we can accelerate the transformation of urban construction management mode, improve the overall urban construction level and operation efficiency, and promote the modernization of urban governance system and governance capacity." Liang Feng, head of the network security and informatization expert group of the Ministry of housing and urban rural development, said. In Guiyuan community, Jiaxing, Zhejiang Province, Aunt Wang, in her 60s, sat in the "5g cloud clinic" to receive remote consultation. "New urban construction" has become an important measure for urban residents to live in peace and contentment. Smart cameras that accurately lock high-altitude parabolic objects, smart trash cans that automatically weigh and count, and smart greenways that scan QR codes to view movement tracks... Through the construction of smart communities, access to high-quality services such as elderly care, fitness and distribution can meet the diversified needs of residents. Moreover, the implementation of a number of "new urban construction" projects is also conducive to promoting industrial upgrading, cultivating new economic growth points and forming new driving forces for development. Promoting the coordinated development of smart cities and intelligent networked vehicles is a key task of "new urban construction". In Xiangcheng District, Suzhou, Jiangsu Province, unmanned buses, taxis and distribution vehicles collectively "work", and unmanned vehicles are equipped with millimeter wave radar, sensing cameras and other sensors. More than 400 sets of intelligent sensing devices and edge computing devices have been installed on the 63.4km high-level intelligent network test road to ensure safety and traffic efficiency. "New urban construction" involves a strong industrial chain. Through the implementation of the project, it will drive the application of new technologies and the agglomeration of new industries, and give birth to the formation of new business forms and the promotion of new consumption. "To carry out 'new urban construction', we should promote the effective coordination of industry, University, research and use, policies and funds, and simultaneously build an 'new urban construction' industrial system with independent and controllable core technology, efficient industrial chain integration and smooth industrial ecological cycle." Liang Feng said. Build a demonstration base and speed up the implementation of "new urban construction" projects Accelerate the "new urban construction" and promote high-quality urban development, and all localities take positive actions. Heilongjiang proposes to implement the smart heating demonstration project, promote urban distributed heating, improve the quality of heating services, and ensure that people live in "warm houses"; Shandong proposes to speed up urban renewal, build and make good use of the "urban brain" in all districts and cities, build 1200 smart communities and create 2000 application scenarios for benefiting the people. "New urban construction" speeds up the release of the great potential of urban development and drives effective investment. At the end of last year, Chongqing issued a special work plan to invest more than 5 billion yuan to promote 38 new urban infrastructure projects, such as the development of intelligent networked vehicles and the promotion of intelligent sensing devices to cover more than 10 kilometers of roads; Carry out more than 100 pilot projects of digital construction of engineering projects, and implement more than 15 million square meters of construction industrialization and information integration projects; By 2025, we will cultivate a number of "new urban construction" leading enterprises and create 100 billion level economic production capacity. "The 'new urban construction' involves a wide range and many levels. It is suggested to give priority to the sectors with good foundation, concentrate on improvement and improvement, make full use of the existing information infrastructure and data resources of the city, and avoid repeated construction." Liang Feng believes that the "new urban construction" should do something or not. The pilot cities can combine the main tasks and develop their specialties according to the construction foundation and funds of each jurisdiction, and promote it step by step. According to the relevant person in charge of the Ministry of housing and urban rural development, the next step will be to accelerate the construction of the basic platform system of national, provincial and municipal urban information model, comprehensively promote the intelligent municipal administration, intelligent community and intelligent construction, jointly develop the intelligent city and intelligent Internet connected vehicles, and accelerate the implementation of the "new urban construction" project by building a demonstration base. At the same time, work with relevant departments to strengthen scientific and technological support and strengthen collaborative innovation of the whole industrial chain; Strengthen security guarantee and comprehensively improve the comprehensive prevention and control ability of network security; Cultivate a talent team, especially vigorously cultivate compound innovative talents with the support of a new generation of information technology, engineering construction and other disciplines.
