With the development of city, the demand on energy saving and intelligent con-trol of street lamp is increasingly high. Aiming at this situation, a monitoring system bas-ed on power line carrier communication technology is established. The system design of software and hardware for concentrator and a control terminal is completed based on PLCchip RISE3501 and MCU chip ATmega16, and remote control of switching and dimming for LED lighting is implemented,then the supply current and voltage waveforms of PLC chip RISE3501 were tested. Finally, the economic benefits of LED lighting intelligent mo-nitoring system are presented.
