基于LonWorks技术的路灯节能控制系统

Design and Application of Street Lamp Supervision Control System on LonWorks

针对高压钠灯的特点,提出串电感调压的路灯节能方法,并结合LonWorks电力载波技术,利用PL3120/PL3150神经元芯片设计并实现了路灯智能控制节点装置。该装置具有对电网无冲击、不影响灯具寿命、安装便捷、无需另外铺设通信线路等优点,从理论分析和实际测试两方面验证了其节能特性。在此基础上,构建了路灯节能控制系统,它具有可预先设定路灯运行状态日程表,对路灯进行单点或批量远程操作,远程实时监控各路灯的运行状态,路灯故障报警等功能。节点装置和控制系统在实际运行中已取得了良好的节能效果。

According to the characteristic of high pressure sodium lamp,the voltage adjustment method by inductances in series is proposed.And with the LonWorks power line carrier technology, a kind of street lamp supervision control device is developed on PL3120/PL3150 neuron chips,which has many advantages such as no harmful effects on power system and street lamps,easy installation,no additional communication lines.The test and calculation values of energy-saving quantity are roughly the same.Furthermore,a street lamp supervision control system which owns running schedule,remote opera- tion, real-time monitoring and failure alarm is also developed on this basis of device.Now the device and system have already run for a long time with significant energy saving effect.
