单片机在智能交通灯控制系统中的应用

MCU in Intelligent Traffic Light Control System Application

介绍一种基于AT89S52单片机的车流量变化动态调节时间的智能交通灯的设计方法,可自动进行流量统计;根据模糊算法分配各车道的绿灯时间,实现车流动态调节。介绍车流量检测的原理与绿灯时间分配方案,针对复杂多变的路况环境,特别增设了紧急情况处理模块,完善了交通灯控制系统。

Here's an introduction of one way to design the intelligent traffic light controller.Based on singlechip AT89S52,it will dynamically adjust the time and collect flow statistics as the traffic flow changes.It can distribute the time of each greenlight on the basis of fuzzy algorithm,so as to control traffic dynamically.The following describes the principle of traffic flow's detection as well as the allocation plan of greenlights' time.Due to the complicated and changeable road condition,we specially add a Emergency Module to it,thus improving the trafffic lights' controling system.
