Distributed Intelligent City Street Lamp Monitoring and Control System Based onWireless Communication chip nRF401 Abstract: Traditional street lamp lighting system’s control style has disadvantage of low efficient, high cost and difficult to monitor, etc, so, it has not met modern city requirement. In order to realize distributed long distance city street lamp state automatic control in real time, we introduces a kind of wireless long distance intelligent city street lamp monitoring and control system based on SCM technology, electric power carrier communication, and wireless communication technology, etc. System is composed of upper PC, main controller, and each terminal controller. Upper PC controls main controller SCM MSP430F19, and transmits control instruction to field controller, MSP430F149 controls corresponding lighting lamp switch’s state changing by wireless transceiver nRF401. Upper PC can effectively complete wireless long distance lighting equipment control in real time. Through experiments, transmission distance can reach 1000m in maximum. In addition, we design illumination monitor equipment, which can assure lamp shut down automatically when communication network failure. Keywords: street lamp monitoring and control; MSP430F149; nRF401; wireless communication; AT89C51; electric power carrier communication I. INTRODUCTION Street lamp lighting is city part of infrastructure, which plays important position at traffic safety, society security, people living, city appearance style and feature, as well as making a city strength and mature degree. Traditional street lamp controlling adopts time-controller or transformer (distribution box) to realize decentralized control, which has disadvantages of bad centralized management, and high failure rate. Due to without long distance data collection and communication function, street lamp management in real time has not been realized, so, lamp working, operation result, etc can not be centralize monitor, re
