基于单片机的十字路口交通灯的设计及仿真

Design and Simulation of Traffic Lights and Digital Voltmeters Based on Single Chip Microcomputer at Crossroads

以单片机为主控制器,设计了单片机硬、软件系统,用Keil编程软件和Proteus仿真软件,以此实现十字路口交通灯的系统设计及仿真。系统的主要功能是用单片机控制数码管进行模拟显示十字路口交通灯的控制情况。设计时,主要采用定时器中断方式实现系统控制,实现两位8段数码管和LED灯显示系统的控制,较好地模拟了交通路面的控制情况。

This design takes the microcontroller as the main controller, and designs the hardware and software system of the single chip microcomputer. The Keil programming software and the Proteus simulation software are used to realize the design and Simulation of the traffic lights at the crossroads. The main function of the system is to simulate the control of traffic lights at the crossroads by single chip microcomputer. In the design, the system is controlled mainly by the interrupt mode of the timer, and the control of the two bit 8 segment digital tube and the LED lamp display system is realized, and the control of the traffic road is well simulated.
