Proteus仿真实例_基于51单片机的交通灯系统（仿真文件+程序）24-51f-10

一.系统概述

交通灯系统使用51单片机进行主控，系统内使用数码管显示各个方向的路灯时间，四个方向上都设置了红绿黄灯，通过按键可以控制交通灯的开启和关闭，还能控制红灯、黄灯全亮以及相应状态进行延时，对于绿灯和黄灯的时间还能通过按键直接进行设置。

二.仿真概述

1. 启动仿真后各个方向的亮灯时间开始进行计时，开始控制

2. 按下启动交通灯按键开始进行计时，

3. 按下红灯全亮按键后所有的红灯都会亮起，此时所有方向禁止通行。

4. 按下黄灯闪烁按键后所有方向的黄灯开始进行闪烁。

5. 按下上方的交通灯时间调节按键就能对红绿灯的时间进行调整。
