基于单片机的交通灯控制系统设计与实现

Design and Realization of Traffic Light Control System based on Micro Controller Unit

以AT89S51单片机为核心器件,设计了多功能交通灯控制系统.软件仿真和硬件实现的结果表明该系统具有红绿灯显示功能、时间倒计时显示功能、左转提示和紧急情况发生时手动控制等功能.

The paper designed multi - functional control system for traffic light with AT89S51 as the central component. The results of the simulation experiment and the hardware implementation indicated that the system has traffic light showing function, time countdown showing function, turn - left tips and manual control keying in emergency situation.
