Abstract：With the rapid expansion of China's rail transit network,its huge operational energy consumption,especially the energy consumption of the lighting,has become a key focus of operational cost control.To achieve green,low-carbon,and efficient operational goals,the research and application of intelligent lighting control technology is crucial.This paper focuses on the energy-saving application of intelligent lighting control systems based on power line communication(PLC)technology in the field of rail transit.It begins with an analysis of the characteristics and current energy consumption status of the lighting system in rail transit stations,followed by an in-depth explanation of the basic principles of PLC technology and its all-round compared to other technologies,especially its outstanding value in terms of simple construction,material saving,and intelligent operation and maintenance management.The core of the paper is the design of a P-based intelligent lighting control system architecture suitable for scenarios such as the station hall and platform of a subway station,which details its hardware composition,communication protocol,and intelligent control strategy,including area control,timing control,light-sensing linkage,and human flow response control.Finally,through the pilot case analysis of a certain site of Wenzhou transit,the energy consumption data before and after the system transformation are compared,proving the remarkable effective ness of the system in significantly reducing lighting energy consumption(with an average energy saving rate of 30％),greatly saving transformation materials and construction costs,and realizing digital operation and maintenance management,providing strong theoretical and practical references for the large-scale promotion of PLC in the field of energy saving in rail transit.
