摘要
AT89C51单片机的交通灯控制系统是由AT89C51单片机、键盘电路、LED倒计时、交通灯显示等模块组成。系统除基本交通灯功能外,还具有通行时间手动设置、可倒计时显示、急车强行通过、交通特殊情况处理等相关功能,实验采用AT89C51单片机为控制芯片,采用"Proteus+KeilμVision2"对交通灯控制系统进行了仿真,仿真结果表明:该系统能够简单、经济、有效地解决交通堵塞问题,提高交通路口的通行能力。
The traffic light control system is composed of modules such as AT89C51 single-chip processor,keyboard,LED countdown timing and traffic light display etc.In addition to basic traffic signal functions,the system has some functions such as manual setup for passing time,countdown timing display,urgent vehicle passing and treatment of abnormal traffic.The ATMEL AT89C51 microcontroller was used as control chip,the＂Proteus＋Keil μVision2＂ was used to simulate the traffic light control system.The system is simple,economical and effective in easing traffic congestion and improving traffic junction capacity.
