基于单片机的交通灯控制系统的设计与实现

The Design and Implementation of Traffic Light Control System Based on Single Chip Microcomputer (SCM)

摘要: 以AT89S51单片机为核心控制单元，结合传感器检测，设计并开发基于单片机的交通灯控制系统。本系统不仅具备基本交通灯功能，而且兼有通信时间手动设置、倒计时显示、车流量检测、红绿交通灯实时调控等功能。理论证明该系统能够简单、经济、有效疏导道路交通，从而提高交通路口的通行能力。

Abstract: Traffic lights control system is designed and developed based on AT89S51 single-chip microcomputer which acts as the core control unit, and integrated with sensor monitoring. This system has not only the basic function of traf- fic lights, but also has the functions of countdown display, manually-set communication time, vehicle flow detection, real-time adjustment of red and green traffic lights, and so on. Theory proves the system is simple, affordable and effective to disperse road traffic, and thus it improves the traffic capacity of traffic crossing.
