The role of smart communities in the construction of smart cities

       With the continuous transformation of the global economy, cities that once emerged as secondary industries such as heavy industry and automobile manufacturing have now experienced global recession. As a governance of urban decline, urban regeneration since the 1990s ( Urban regeneration) is one of the key words of urban policy in Western countries.

       The London Planning Advisory Committee’s Lichfield 咋 “City Regeneration in the 1990s” defines the term “urban regeneration” as: using a comprehensive and integrated perspective and action-oriented approach to solving urban problems in order to seek a region The economic, physical, social and natural environmental conditions are continuously improving.

       In the past 40 years of reform and opening up, the speed of urbanization in China has accelerated markedly and remarkable achievements have been made. With the beginning of the fourth industrial revolution, the speed of urban renewal has lagged behind the speed of urban development. In Beijing, Shanghai and other cities, there are still a large number of buildings, communities and urban villages built in the 1940s and 1880s. As a basic unit of urban population life and a basic unit of urban composition, the community has transformed the community. It is one of the important channels for urban redevelopment and urban regeneration.

Intelligent construction of demolition and resettlement community

       With the vigorous development of China's economy, all localities are vigorously developing and building, and “demolition” has become a hot word. On the one hand, due to the limited land construction area, demolition is the optimization and redistribution of land resources; on the other hand, there are a large number of shanty towns, The existence of the village in the city not only affects the appearance of the city, but also has a large number of security risks. The construction of the demolition and resettlement community is also developing intelligently. For example, the demolition and resettlement community of the wild town of Taizhou High-tech Zone, the Happy Community, has built a multi-integration of intelligent face recognition system, intelligent property system and public security control system. Wait for the "smart community" big data platform.

       The intelligent construction of the demolition and resettlement community has met the community residents' yearning for a better life, made the residents of the community safer and more convenient, and fully enjoyed the construction and development dividend of the smart society and digital China. At the same time, it can attract more middle- and high-class users who pursue high-quality life, and promote the development of related industries and the improvement of urban quality. This is a process of complementing each other and promoting each other.

Green and intelligent transformation of existing communities

       It is well known that a white paper is a good drawing, and the demolition is the process of painting the paper and painting it again. However, in the big cities of Beijing, Shanghai, Nanjing and other large cities, the process of “painting white” in some old communities and urban villages is very difficult and costly. There are also some problems in the protection of history and culture in some communities, streets and Hu.

       Therefore, the use of informatization and technical means to intelligently transform the community is an effective way to achieve community regeneration. Dai Binbin, head of Haidian District, Beijing, said that Haidian will carry out smart construction pilot projects in 40 communities this year. At least 18 smart technology application scenarios such as smart manhole covers, smart elevators and water quality monitoring will enter the public life. He cited examples of the North Dock Jiayuan community that had just begun piloting. For example, the community door will have a face recognition system and a vehicle information collection system. The smart elevator will promptly remind some citizens of the uncivilized behavior; the water supply system will be able to monitor the drinking water pipe network in real time. The water quality of the nodes prevents the water and other pollution; the environmental system will be able to grasp the air quality and noise pollution in the community in real time.

        The industry standard for the “Technical Standards for Greening of Existing Communities” issued by the Ministry of Housing and Urban-Rural Development in 2017 provides standard support for the green transformation of existing communities. For the green and intelligent transformation of existing communities, the old community will be revitalized, and the traditional old community will be replaced with a green and intelligent community that fits the needs of the times and the needs of the city.

Building an open community

        Due to the traffic congestion, difficult parking and limited land resources in the city, the voices of opening community fences are constantly on the way, and relevant policies and measures for connecting with the international community and building open communities are also being introduced.

        In 2016, the Central Committee of the Communist Party of China and the State Council issued the "Several Opinions on Further Strengthening the Management of Urban Planning and Construction." The document states that China's new residential buildings should promote the block system, and in principle no closed residential quarters will be built. The completed residential quarters and unit complexes should be gradually opened to realize the internalization of internal roads, solve the problem of transportation road network layout, and promote land use and utilization.

        In fact, most countries and regions in the world have no communities. For example, in developed countries such as the United States and Japan, residential buildings are directly facing the streets or alleys, and only a few luxury houses have walls.

        For example, Guangzhou Kesheng Vanke Central Park aims to build a park-like community that is “livable, suitable, suitable, and accessible” in a way that “residents create together”. However, in the process of actual construction and operation and maintenance of open communities, there are many problems. The difficulty of property management and operating costs of open communities will generally increase. Community residents have doubts about security and safety issues. The flow of people occupies community resources and so on.

        In the new era, intelligent and informational means can effectively solve some problems. The peak parking between residents and white-collar workers is guided and charged by intelligent means, and the control of intelligent security systems is strengthened by smart door locks and other equipment. The safety protection of the unit building, the organic integration of community greening and park greening, also provides a high-quality greening environment for the community residents.
