With the promotion of smart lighting and smart light poles, energy-saving LED is more suitable to replace high-power sodium lamp, which can not only save considerable power consumption, but also reduce environmental pressure. At the same time, with the rapid development of the automobile industry, China's dependence on foreign oil consumption continues to increase, reaching 58.1% in 2013, and the situation of oil shortage is growing. The development of electric vehicles is of great significance to China. On the one hand, it can improve the substitution of electric energy and effectively reduce energy consumption per unit GDP; on the other hand, it can effectively break environmental constraints and solve atmospheric pollution problems such as haze. Therefore, an integrated design scheme based on LED municipal street lamp and electric vehicle charging pile is proposed, which can effectively use the power distribution capacity saved after the transformation of municipal street lamp to install charging pile. The integrated charging piles widely distributed in urban streets provide an interface for electric vehicle charging and discharging while ensuring efficient road lighting. They have the functions of protection, monitoring, control, communication, metering, etc., which is convenient for the master station system to realize remote monitoring and control of street lamps and electric vehicle charging and discharging status. This scheme has strong feasibility and is suitable for large-scale promotion. It can well solve the problem of land acquisition during the construction of charging piles and charging stations.

With the promotion of urban development, smart cities are constantly improved, urban WIFI hotspots are covered, urban small micro base stations are covered, urban road video monitoring, urban sensor layer (PM2.5 monitoring, traffic flow monitoring, etc, It will become a major trend in the future. At the same time, the public resources of municipal roads are used reasonably to avoid waste of duplicate resources.
