基于89C51智能交通灯系统的设计与仿真

Design and Simulation of an Intelligent Traffic Light System Based on 89C51

基于AT89C51单片机为核心控制器,采用ISD2560作为语音录放模块,以及MAX692"看门狗"模块提高抗干扰能力,设计十字路口的交通灯智能化控制系统。实现正常时段交通信号灯的轮换,车辆闯红灯实时监控报警、紧急通行控制、语音录放、数码管倒计时等功能。利用Proteus和Keil软件对系统进行了仿真,结果表明对实现交通的快捷以及缓解交通压力具有较强的可靠性。

The paper introduces an intelligent control system of crossroads based on AT89C51 microcontroller as the core control device, using ISD2560 as voice recording module and MAX692“watchdog”module to improve the anti-jamming capability. The system completes the normal rotation of trafifc lights, real-time monitoring and alarming of vehicles running red lights, emergency trafifc control, voice recording and digital tube countdown function. Proteus and Keil software simulation results show that the designed system has strong reliability on the shortcut trafifc and ease trafifc pressure.
