基于单片机的十字路口交通灯控制系统设计

Design of Traffic Light Control System at Crossroads Based on Single Chip Computer

对目前交通控制现状进行深入分析与调研的基础上,设计出了一个较为完善、功能强大的十字路口交通灯控制系统。该智能交通灯控制系统由51单片机、LED信号灯以及双位共阴极数码管、红外计数模块、蜂鸣报警模块等组成。系统除实现基本交通灯的倒计时以及信号切换功能外,还可通过按键切换不同的模式,如实现夜晚慢行模式、禁行模式、优先紧急车通过、违规报警等模式,经仿真验证该系统具备车流量检测及调整、闯红灯判断及处理等相关功能。该设计能够实现预期控制目标,提高交通道路的通行效率。

Based on an in-depth analysis and investigation of the current traffic control situation,a relatively complete and powerful crossover traffic light control system is designed in this article.The intelligent traffic light control system is composed of 51 single chip microcomputer,LED traffic light and two-bit cocathode digital tube,infrared counting module and buzzer alarm module.In addition to realizing the countdown of basic traffic lights and signal switching functions,the system can also switch different modes through buttons,such as realizing the night slow mode,forbidden mode,priority emergency vehicle passage,and illegal alarm,etc.It is verified by simulation that the system has the related functions such as vehicle flow detection and adjustment,red light running and processing.The design can achieve the expected control goal and improve the traffic efficiency of the road.
