基于单片机控制的交通灯设计
esign of traffic lights based on SCM
本系统采用STC89S系列单片机来设计交通灯控制器，实现了各方向车辆、行人轮流通行的功能，此外还设置人性化倒计时显示。同时还具有南北、东西方向强制通行功能。各方向红绿灯由P1口控制，倒计时显示数码管由P2口控制，强通靠中断来实现。系统中用到74LS245和74LS47，用来驱动LED灯和数码管显示。本系统实用性强、操作简单、扩展功能强、便于维护。
his system uses STC89S MCU to design traffic signal controller,realized the function of all direction of the vehicle and pedestrian through in turn,in addition,sets the human countdown show.It also has a north-south, east-west traffic enforcement functions.The direction of traffic lights controlled by the P1 port,Digital countdown display controlled by the P2 port,forced through by interrupts.The system used in the 74LS245 and 74LS47,Used to drive LED lights and digital display.This system is practical, simple operation, expansion, strong function, easy to maintain.
