基于无线传感网络的城市照明控制系统

摘要

设计了基于无线传感网络的城市照明控制系统.系统以ZigBee网络为核心,主要由路灯节点控制器(LCU)、照明回路控制单元(RTU)和照明管理中心组成.LCU安装于城市街道路灯,实时采集路灯工作状态和环境数据;RTU负责数据收发并通过GPRS传输给照明管理中心;管理软件通过数据处理,实现单灯控制、路灯多策略控制、故障报警等功能.测试结果表明,该系统具有成本低、性能稳定、节能效果好等特点,适用于城市街道、公园、住宅小区等场所.%An urban lighting control system based on wireless sensor networks is designed.The system uses ZigBee networks as the core,which is composed of the light controller unit (LCU),the terminal unit (RTU) and the lighting management center.LCU is installed in the city lights for real-time data acquisition of working status and environment.RTU is responsible for sending and receiving data to lighting management center via GPRS.The functions such as single lamp control,multi-policy streetlight control,automatic alarm,can be realized by data processing of the management software.The result shows that the system has lower cost,stable porfomance and good energy-saving,and is fit for city streets,parks,living areas and other places.
