The dual-mode centralized controller is a gateway device for distribution cabinets based on the hybrid communication technology of power line carrier (PLC) and low-power wireless (RF433). It aims to solve the problems of heavy workload of road light inspection and operation in urban lighting, inability to manage uniformly without intelligence, and high energy consumption of lighting. Through the hybrid and complementary high reliability networking of power line carrier and air wireless dual links, the unified management of single lamp controllers is integrated into the lighting management platform, achieving intelligent centralized management of lighting such as remote on/off control, intelligent dimming, remote monitoring, and data acquisition of street lamps. Intelligent control and unified monitoring of single street lamps, multiple groups of street lamps, and all street lamps, with centralized and efficient intelligent lighting management for multiple points.
