近年来随着科技的飞速发展,单片机的应用正在不断深入,同时带动传统控制检测技术日益更新.在实时检测和自动控制的单片机应用系统中,单片机往往作为一个核心部件来使用,仅单片机方面知识是不够的,还应根据具体硬件结构软硬件结合,加以完善.
十字路口车辆穿梭,行人熙攘,车行车道,人行人道,有条不紊.那么靠什么来实现这井然秩序呢?靠的就是交通信号灯的自动指挥系统.交通信号灯控制方式很多.本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器,实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮,倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出,显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示.本系统实用性强、操作简单、扩展功能强.
With the rapid development of science and technology in recent years,SCM applications are deepening at the same time promote more traditional control detection update.In real-time detection and control of the microcomputer application system,the microcontroller is often used as a core component,only the SCM knowledge is not enough,should be based on specific hardware architecture hardware and software,to be perfect.
Crossroads shuttle vehicles,pedestrians bustling,car dealers Drive,people walkways,orderly.Then rely on to achieve the discipline of the order then?Rely on the automatic traffic light is the chain of command.Many ways to control traffic lights.In this system,MSC-51 Series MCU ATSC51 and programmable parallel I / O interface chip 8255A-centered design of traffic signal controller device to realize the actual traffic volume by 8051 according to the P1 port chip set of red,green time kindle function; traffic light cycle of light,countdown 5 seconds left when the yellow light flashing warning (traffic lights signal output port through the PA,indicating time directly through the 8255's PC port to double-digit output of the digital control); vehicle ran a red light alarm; green time can detect vehicles flow can be by double-digit digital display.The system practical,simple,powerful extensions.
