摘要
智能交通信号机的研制,一方而可以改善交通堵塞问题、疏导车流、提高道路利用率,同时可以节省交通警力,提高效率。设计的这套LED交通灯控制系统,采用电流环加串/并转换的远程弱电隔离控制方式,使系统可靠性得到很大提高,而且控制简单、电路少、距离远、安装方便、系统升级扩充性好,具有很高的实用价值,在国内已逐步得到应用。论述信号控制机的结构、基本功能及主程序流程图,介绍LED交通信号灯系统设计方案。
Intelligent traffic signals on the development, can improve traffic congestion, ease the flow of traffic and improve utilization of the road, traffic police can save and improve efficiency. LED traffic lights control system, plus a current loop string / converter and remote control weak isolation,greatly improving system reliability,and simple control circuit less distance, easy installation, system upgrades scalable, highly practical value,in China has gradually been applied. It discusses signal control of the structure, function and basic flow chart of the main program, introduced by the LED traffic lights system design.
