The invention is applicable to a streetlamp lighting system, and provides an intelligent light streetlamp centralized control system, including a remote monitoring center, at least one centralized controller and at least one streetlamp controller for controlling the work of the streetlamp and monitoring the working condition parameters of the streetlamp in real time, wherein the centralized controller is connected to one or more streetlamp controllers by a power line, and performs transceiving of same information with the streetlamp controller in both power line carrier communication and radio communication modes; the streetlamp controller is used for sending the monitored working condition parameters of the streetlamp to a remote monitoring center, and executing corresponding control operation on the streetlamp when receiving a monitoring command transmitted by the centralized controller from the remote monitoring center. The intelligent light streetlamp centralized control system can achieve comprehensive upgrading of urban public lighting management systems, reduce energy consumption, and achieves centralized control of the streetlamps, informatization of operation and maintenance and intelligentization of lighting.
