The smart street light system is a new system concept proposed in the background of the informatization era. Specifically refers to the use of information technology as a carrier to build an automated, intelligent, and systematic street light service system to ensure that the lighting service function of the city is more comprehensive, and it can also realize the integration of relevant data resources. Under normal circumstances, the smart system of street lights includes three major modules, which are usually based on street light nodes, data management centers and information public platforms. The data management contains three small modules, which refers to the data of street lights, environment and transportation. Taking information technology as a carrier, constructing an intelligent street lighting system can comprehensively optimize the function of street lighting systems and comprehensively improve the quality of street light services. Therefore, relevant departments need to attach importance to the construction of smart street lights and build a smart city. Only in this way can we promote better development of urbanization construction, comprehensively improve the level of urban construction, and meet the new requirements of modern people on traffic services
