交通在人们的日常生活中占有重要的地位,随着人们社会活动的日益频繁,这点更是体现的淋漓尽致.交通信号灯的出现,使交通得以有效管制,对于疏导交通流量、提高道路通行能力、减少交通事故有明显效果.本系统采用单片机AT89C51为中心器件来设计交通控制灯控制器,系统实用性强、操作简单、扩张性强.本设计就是采用单片机模拟十字路口交通灯的各种状态显示以及倒计时时间.
本设计系统由单片机I/O口扩张系统、交通灯状态显示系统、LED数码显示管系统、紧急情况中断系统、复位电路等几大部分组成.系统除基本的交通灯功能外,还具有倒计时、紧急情况处理功能,较好的模拟实现了十字路口可能出现的状况.
软件上采用89C51编程,主要编写了主程序,LED数码显示管程序,中断程序延时程序等.经过整机调试,实现了对十字路口交通灯的模拟.

Traffic in people's daily life plays an important role,as people have become increasingly frequent social activities and this is reflected most vividly.The emergence of traffic lights so that traffic can be effective control,for ease traffic flow,increase road capacity and reduce traffic accidents have a demonstrable effect.The system uses microcomputer AT89C51-centric devices to design the traffic control signal controller,the system practical,simple operation,expansion and strong.This design is the adoption of SCM simulation of traffic lights at the crossroads of various status display and countdown time.
This design system is composed of MCU I / O port expansion systems,traffic light status display system,LED digital display control systems,emergency interrupt system,reset circuit of several major components.In addition to the traffic light system,the basic functions,but also has a countdown,emergency processing functions to achieve a better simulation of the situation that may arise at a crossroads.
Software using 89C51 programming and wrote the main program,LED digital display control program,interrupt program delay procedures.After machine commissioning,implementation of the simulation traffic light intersections.
