Research And Implementation Of Urban Streetlight Monitoring And Control System

Now,building the saving-type society and environment friendly society has become the important national policies.The proportion of electrical power of urban lighting,especially street lighting,occupy increasing,and the serious waste of electrical energy,so saving of street lighting is imperative.This subject analyzes on various energy saving methods,selected PWM IGBT single-phase AC/AC direct voltage regulation technology,and improved and simulated to it.This subject seleted control processor ARM7 processor and communication processor Echelon PL3120 as the core of the double processor of distributed monitoring devices,and design lamp system structure.In the network topology structure based on the large streaming network of multilayer peer-to-peer network,and proposed the way LonWorks network method of automatic relay of with conditions.This subject has basically completed hardware and software implementation of the street lighting monitoring and control system.
