文档介绍：基于16位单片机的交通灯电路设计
摘要
要对路口交通灯进行合理的控制,除了要采集真实的数据,并作合理的分析外,还需要建立模拟交通灯控制系统, 的强大的处理能力,控制交通灯控制模组,进行实际交通情况的模拟,模拟交通灯控制板就是通过使用单片机、PLC 或其它器件控制一些LED 和数码管,来模拟真实十字路口的交通灯的功能。如模拟红黄绿灯交替闪亮、倒计数显示时间、,定时/计数器和中断的功能、工作原理。如何将程序下载到单片机的闪存Flash中。

The Design of Circuit of Traffic Lights Based on 16-bits Single Chip puter
Abstract
In order to give a reasonable control, you should sample real data and make rational analyze and set up model traffic light controlling system, carry on model controlling to the real state of the traffic lights based on this platform. Making use of the power processing function ,this system controls the controlling mode of the traffic light and operate the simulation of the real traffic state, analog traffic lights controlling board simulate the function of the real traffic lights at the crossing by using SCM、PLC and other applications to control LED and nixie light. For example simulating the shining of the RED 、YELLOW、GREEN light by turns and showing time in countdown model and make use of direction light to indicate the right direction and so on. The purpose of this paper is understand the inner structure of SCM and timing/counting and interruption function and operation principle and how to make the program download to the flash of SCM. The paper can make us master some relative knowledge of circle and SCM.
