基于Proteus和8086的交通灯控制电路仿真设计

Traffic Lights Control Circuit Simulation Design Based on Proteus and 8086

文章介绍了基于INTEL8086微处理器的十字路口交通信号灯控制系统,该系统在Proteus平台下进行电路设计,利用定时计数器8253和中断控制器8259产生定时中断信号,通过中断控制并行可编程接口芯片8255A驱动十字路口交通信号灯的切换和七段数码管的倒计时显示.该系统软件设计利用EMU8086软件完成,在Proteus联合EMU8086编译环境下进行了系统仿真运行,运行效果良好.

To introduce the intersection traffic signal control system based on microprocessor INTEL8086,the system in the Protews platform for circuit design, using the timer counter 8253 and interrupt controller 8259 produce the timer interrupt signal, through the interrupt control programmable parallel interface chip 8255A drive intersection traffic signal lamp switch and seven segment digital tube of the countdown display. The system software design using EMU8086 software to complete, under the environment of Protews joint EMUS086 compile the simulation run, run the effect is good.
