为提高道路照明系统控制的可靠性、便捷性和灵活性,并达到节能降耗的效果,设计了一套路灯远程监控系统。系统包括路灯控制终端和上位机软件两大部分。路灯智能控制终端基于AVR单片微处理器开发,集远程手动控制、定时开关控制和光感自动开关控制于一体,增加了路灯远程控制方式的多样性;采用定时-光感协调控制技术,弥补了独立的光感自动控制抗干扰(外界光源、遮挡等)能力差的不足。上位机软件基于Visual C++6.0编程环境开发,具有控制模式切换、参数配置、接收信息显示等功能。采用无线通信方式,减小了布线的难度,缩短了建设的周期。
In order to improve the reliability,convenience and flexibility of road-lighting system,and save the electrical energy,a street-lamp remote monitoring system is designed in this paper.This system is consisted of a terminal controller and a monitoring program in host computer.The terminal controller is developed by using AVR microcontroller,and remote manual mode,timing mode and light-dependent mode are integrated,which improve the diversity of street-lamp remote controlling.Meanwhile,a coordination control method combined with the timing and light-dependent modes is presented,which overcomes the defects in resistance to interference(irradiated and sheltered conditions,etc.)of traditional light-dependent mode.The monitoring program is developed with Visual C++ 6.0.This program can switch the operating mode,set the parameters and display the receiving data.The wireless communication is adopted and as a result,the work of cabling can be saved and the construction cycle of system can be reduced.
