Smart City System Research Based on Smart Street Lights
As an indispensable part of the municipal infrastructure - street lights, visible everywhere on the road. The planning of the urban road network determines the wide distribution of street lamps in the city and the comprehensiveness of coverage. Due to these characteristics, street lights have become the preferred carrier for smart devices in cities. The construction of smart cities combines smart facilities with street lamps and carries out various innovations on street lamps. The use of street lighting pipeline networks to build the Internet of Things in smart cities, thereby building smart cities and highlighting the level of urban management. Therefore, this paper uses streetlights as the carrier of urban smart infrastructure, studies its role in the construction of smart cities, and designs and analyzes smart city systems to design for smart cities and the use of smart infrastructure for human society. Bring happiness.
1. Intelligent design of urban system architecture
The core of smart city is to influence or change people and people in the city through modern information technology. An intelligent way of intrinsic connection with things, things and things, so that the city has a clear target direction, improve the efficiency of the city, and achieve the perfect combination of the city information infrastructure and the highly integrated infrastructure of the city, making the city government Businesses and citizens can make more informed decisions. In general, the system architecture of a smart city can be divided into four levels.
1.1 Perceptual Layer
The perception layer is mainly the ability to quickly sense and monitor information networks, based on the network covered in the city. The corners are supervised to make the information obtained more transparent and complete. Smart street lights collect information based on wired networks, wireless networks, video broadcasts, charging piles, etc., so that they can quickly collect useful information for the city, and then integrate various resources to achieve “sharing, intensive, and Co-ordination, significantly reducing urban construction costs, improving urban operation and maintenance efficiency, and bringing multiple benefits to the construction of smart cities. The comprehensive coverage and intensive shared city perception network built by smart street lamps can provide various types of integrated sensing information such as video, data, location and environment for the upper-level intelligent application systems.
1.2 Network Layer
The network layer is composed of the Internet of Things, the Internet, and the communication network in the entire city. The information is collected and its security is greatly guaranteed. The high-speed and ubiquitous communication network is constructed by using the light pole of the light pole and the main pole, including: fiber-optic network, wired wireless network such as 4G/5G micro base station and WiFi equipment. Provide a good information application environment for smart cities, so that all kinds of data, voice, video, images, etc. can be effectively coordinated on the inside and outside of the city. The combination of modern communication technology, computer technology and other high-tech technologies fully reflects the trend of fiber-optic, wireless, integrated and intelligent information development. An advanced information communication infrastructure network and business network will be built in smart cities to meet the various information communication business needs of the city's management applications.
1.3 Platform Layer
The platform layer is composed of various applications supporting the public platform and data center. The main collection of data comes from the front end of the smart street lamp. Inductive equipment to achieve effective and scientific processing of information. Based on the smart city cloud computing data center, the data exchange platform is the core. Construct a unified public application support platform, information resource management system, data exchange platform, key information resource database and information resource catalog database to promote the intensive construction of urban informatization, enabling various infrastructures in the city to transform IT technology. So that the city can share information, and then use the integration layer to integrate information, which can ensure the efficiency of information collection and the security of information.
1.4 Application Layer
Application layer is from the urban management of the smart government, to the wisdom of home life and the management of every little thing around the people. application. This level is oriented to scientific research institutions, government administration departments, and citizen users. Research institutions collect and research data, predict results, and support data for government decisions. The government management department has strengthened the management of municipal infrastructure, the control of traffic safety, and the formulation of policies, so that decision-making can be developed steadily. Once problems arise, timely monitoring and management can also be carried out. Under special circumstances, the government management department can issue emergency broadcasts or emergency notices through smart street lamps to timely evacuate the occurrence of dangerous accidents and effectively reduce the harm caused by accidents. Vigorously for the public users, it is released through the front end of the smart street lamp, providing users with more service information such as more weather reports, real-time reports of road conditions, and also supporting electric vehicles for charging and other measures.
Relying on the data integration and business collaboration capabilities of the application supporting the public platform, planning and promoting the construction of large-scale smart application projects, selecting and arranging a group of social and livelihood results is obvious and beneficial The key wisdom demonstration project with low carbon economy development and mature conditions will start the market with government wisdom application construction and procurement, encourage enterprises to innovate service methods and products, provide diversified intelligent people's livelihood services, and gradually build intelligent application systems and pass The intelligent integration between the systems gradually increases the depth of each application from the department level to the city level.
2, Conclusion
Street lights are essential equipment for urban construction, distributed in various parts of the city, with the development of society, let Street lights carrying different smart devices have gradually become a development trend. This paper puts forward the construction of smart city system architecture based on the construction of smart street lamps, making the city more intelligent and making the management of the city simpler and more efficient.
