The high power LED street lamps are mostly driven by constant current. The luminous intensity of lamps has nothing to do with the environment brightness,illumination time,the traffic flow,and etc. It causes energy waste and device maintenance difficultly. This article describes the design of an addressable LED street lamp intelligent monitoring system,which is based on power line carrier communication. It realizes intelligent dimming by detecting environment brightness together with adaptive dynamic PWM modulation technology. Through SENS-01 module and addressable technology,it could also realize the cable monitoring,lamp fault positioning and intelligent monitoring. It is a system of energy-efficient,ecofriendly,multi-functional,high reliable and intelligent management.
