智能交通灯控制器的设计

Design of an intelligent traffic light control system

现代社会对交通运输日趋依赖,传统的交通灯控制系统已经表现出明显的缺点:红绿灯时间相对固定,不能随车流量的改变而调整红绿灯的显示时间。基于上述原因,设计了一种简易的智能交通灯控制器系统。首先介绍了交通灯控制系统的设计方案,以单片机AT89S51芯片为中心来实现智能控制;接着用汇编语言在Keil环境下进行编程调试,通过软件Protues实现硬件仿真,最后将软件系统与硬件联调,实现了以下功能:绿灯时间可检测车流量并可通过双位数码管显示,能根据实际车流量自动设置红绿灯燃亮时间;红绿灯循环点亮,倒计时5s时黄灯闪烁警示;车辆闯红灯报警。该控制器系统在很大程度上缓解了交通压力,解决了繁华道路交通堵塞等情况。

In recent years, traffic light has become quite a serious problem in our social, the traditional traffic control sys- tem has shown clear weakness： relatively fixed time traffic lights, can not adjust to changes in traffic flow with traffic lights in the display time. In order to the above questions, it is inefficient to design a simple intelligent traffic control sys- tem. At first, the design scheme of the Intelligent Traffic Light Control System was introduced, Single chip AT89S51 was Mainly used for intelligent control system, using assemble language in Keil environment for programming and debug- ging, Protues realization software hardware emulation, in the last, has realized the fowling function： can be set according to actual traffic flow at traffic lights brighten the function of time; the traffic light cycle of light, yellow light flashes when the countdown 5 seconds warning; police vehicles running red lights; green time of traffic flow can be detected by double-digit digital display.
