Background: With the rapid development of social economy, people travel more and more frequently at night, and street lighting at night has become a top priority in urban construction. Street lights are an important part of the city's lighting project and are being paid more and more attention by the government. A large amount of capital investment has made our city bright and colorful at night. But problems have also followed. A large number of street lighting not only causes increasing energy consumption, but also causes problems such as excessive electricity bills to become more and more prominent, and the resulting maintenance amount has also increased accordingly. Especially now that society requires environmental protection and energy conservation, it brings more serious technical challenges to our street lighting.    

Introduction to the results: The street light controller has remote monitoring functions and can participate in the primary frequency modulation of the power system to enhance the stability of the power system. The street light controller can communicate with the master station. There is no limit to the communication method, and it can be wired communication or wireless communication. The main station can issue instructions such as on, off, and brightness, and the street light controller controls the switching and dimming of the street light. The street light controller collects data such as voltage, current, power, power consumption, and power grid frequency of the street light. When the main station sends a query command, the voltage, current, power, power consumption, power grid frequency and other data collected by the street light controller can be sent to the main station, as well as the status information of on, off, and brightness, for monitoring the operation of the street light. status.
