Design and implementation of street light control system based on power line carrier communication

Abstract Traditional street light control systems only support manual control, photosensitive control, and simple timing control while the energy utilization rate is low and the operators cannot monitor the working state of the street lights in real time, which causes great inconvenience to management and maintenance. This paper designs an intelligent street light control system based on power line carrier communication, which effectively utilizes the power grid resources. In view of the shortcomings in the insufficient distance of power line carrier communication, the signal relay method is adopted to effectively extend the communication distance. It realizes the real-time control and management of street lighting, therefore, meeting the need of intelligent lighting. The experimental results show that the system runs stably and reliably to have great popularization value.
