1、摘要本论文针对我国城市路灯系统路灯分布广、损坏率高，路灯管理部门排除故障迟缓日．费时、费力、费钱，以及现有传统路灯控制方式存在种种不足的管理现状，运用最新的测控技术结合GPRS(GeneralPacketRadjoServjce)公崩通信网技术、nc(Power1．inecomunication)电力线载波数据传输技术与计算机技术，没计城市路灯监视控制及数据采集系统，简称sCADA(Supervisorycont，rolAndDataAcquisition)系统，以实现对城市路灯系统进行远程的遥控、遥测、遥信和遥视

2、，达到节能、安全及城市路灯系统维护管理现代化和科学化的目的。论文主要工作在于系统方案的论证，硬件、软件的设计，对电力线载波通讯模块传输特性及抗干扰实验的研究，对系统实验结果的分析，对系统经济、社会效益的分析。结果表明，本系统在对路灯进行远程遥控、遥测、遥信和遥视的同时，实现了对单个路灯的点控并有效地将工作电流降低了50％，功率因数从O．8提高到()．9以卜，且其启动电流大大降低，小于O．75A，不仅延长了路灯寿命，而目提高了能效比，降低了线路损耗，达到了真正意义上的节能。关键词：城市路灯，智能监控，GPRs，PLc
