8051在车辆超速报警系统中的应用

The application of 8051 in vehicles overspeed alarm system

设计了一种利用8051单片机对机动车超速行驶情况进行蜂鸣报警和灯光报警的系统。该系统结构简单,可靠性高,操作方便,可广泛应用于摩托车、汽车等机动车辆。详细介绍了系统的总体设计方案,给出了界面模块与8051接口电路,最后介绍了软件设计方法及程序流程图。

Design a sound alarming system using 8051 singlechip which can exam the overspeed motor vehicle and meanwhile give out sound. The system with simple structure?high reliability and convenient operation can widely used on motorbike?car and so on. This paper detailedly introduces the whole design scheme of the system?the circuit on interface module and 8051?the method of the software design and program flow chart.
