| 摘 要： | 城市交通信号灯模拟控制系统模拟了能够对信号灯进行远程投时的城市十字路口控制系统功能。借助于单片机开发板上的已有资源，构建了模拟实际系统功能的单片机扩N82C55控制LED灯模块、8位七段数码管显示控制模块和板上扩展接线模块。在分析实际系统工作流程的基础上，给出了针对单片机开发板的模拟系统C51控制程序流程。用于实际系统时，只需要将代码移植到现场设备并进行具体设置和适当修改即可，可以在满足客户需求的前提下最小化系统开发成本。

| Abstract: | An analog control system for city traffic light signals is presented. The system composes of three components including the LED lighting controlled by 82C55, the seven-segment LED with 8 bits displaying and the extend-terminal via a single chip microco that implement the control logical rules of traffi mputer. The analog control system c lights. And these routines can be is embedded with C51 routines also served as other purposes by appropriate settings according to specific applications. |
