基于PLC智能控制系统的十字路口交通灯的研究设计
摘 要
随着社会经济的发展，城市交通问题越来越引起人们的关注。人、车、路三者关系的协调，已成为交通管理部门需要解决的重要问题之一。城市交通控制系统是用于城市交通数据监测、交通信号灯控制与交通疏导的计算机综合管理系统，它是现代城市交通监控指挥系统中最重要的组成部分。
针对近年来城市交通的拥挤现象,特别是驾驶员违章严重、交通事故频发、车辆尾气污染等问题,介绍丁集计算机、信息、电子及通讯等众多高新技术手段于一体的智能交通指挥中心控制系统.该系统的安装及使用,大大缓解了城市道路堵塞现象、提高了道路的通行能力.减少了驾驶员违章的次数,抑制了交通事故的发生,同时对减轻车辆尾气排放,从而降低环境污染都起到了不可低估的作用.
分析了现代城市交通控制与管理问题的现状，结合城乡交通的实际情况阐述了交通灯控制系统的工作原理，给出了一种简单实用的城市交通灯控制系统的硬件电路设计方案。

Abstract
With the development of social economy, the urban transportation problem more and cause the attention of people. People, vehicles, and the coordination of the relationship, the traffic administrative department has become one of the important problems need to be solved. Urban traffic control system is designed for the urban traffic data monitoring, traffic light control and transportation of the dredge computer integrated management system, it is the modern urban traffic control command system, the most important part.
Aim at in recent years hustle of city transportation phenomenon, especially the pilot be illegal severity, traffic accident Pin hair, vehicle tail spirit pollution etc. problem, introduction the D gather numerous Gao Xin technique meanses, such as calculator, information, electronics and communication...etc. in the commanding center of the intelligence transportation of the integral whole control system.Should system of install and usage, consumedly alleviated city road to stop phenomenon, exaltation go through of road ability.Decrease the illegal number of times of pilot, repressed traffic accident of occurrence, in the meantime to ease vehicle tail spirit emissions, lowered pollution of the environment to all have thus can't under-estimation of function.
Analysis the present condition of modern control and management problem of the city transportation, combine city country transportation of actual the circumstance elaborated a transportation light control system of work principle, give a kind of simple practical city transportation light control system of hardware electric circuit design project.
