摘要在道路交通事故中，车辆超速行驶时引起事故的主要原因之一。

由驾驶员超速驾驶造成的交通事故不断涌现，对控制汽车在安全车速内行驶的研究逐渐成为各国关注的焦点。

本设计是一个单片机控制的车速报警系统，从驾驶员自身安全角度出发，设计了一种检测车辆超速的报警系统。

当车辆处于行驶状态中，该系统通过速度传感器时刻监测机动车辆。

并通过LED显示车辆的实际速度和用户安全参数，当发现车辆速度超过驾驶员设置的最高值时，蜂鸣器开始报警，警告灯不断闪烁，提醒驾驶员减速。

该系统结构简单，操作方便，可用于多种机动车辆。

AbstractIn road traffic, vehicle speeding is one of the most important reason to cause an accident. Driving, accident caused by driver speeding constantly emerging, control vehicle traveling within the safe speed is becoming the focus of national attention . This design is a single-chip microcomputer to control the speed of the alarm system, starting from the driver’s own security, alarm system was designed for detecting vehicle speed. When the vehicle is in the running state of the system, the speed sensor is monitoring of motor vehicle. And through the actual speed and user security parameter LED display vehicle, when the vehicle speed exceeds the maximum value set by the driver, the buzzer alarm, warning lights flashing, to remind drivers to slow. The system is simple in structure, convenient in operation, can be used for a varrety of motor vehicle.Keywords: automobile; overspeed alarm system; 8051; sensor; alarm.目录前言 (4)1．系统方案原理及特色 (5)1.1超速报警器设计思路 (5)1.2超速报警器的总原理图 (5)1.3超速报警器的特色 (6)2．超速报警器硬件设计 (6)2.1主控模块 (6)2.2 时钟电路 (8)2.3复位电路 (9)2.4霍尔传感器连接电路 (10)2.5按键电路 (12)2.6显示电路 (12)2.7报警电路 (13)3．超速报警器软件设计 (14)3.1 程序流程图 (14)3.2程序设计 (14)结论 (19)参考文献 (20)致谢 (21)汽车超速报警系统前言随着汽车工业的不断进步,行驶在道路上的车辆越来越多,交通事故发生的频率也不断增加。

汽车电子超速报警系统摘要近年来,随着汽车工业的不断进步,行驶在道路上的车辆越来越多,交通事故发生的频率也不断增加。

众所周知,交通事故的发生大部分就是由驾驶员的超速驾驶造成的。

研发汽车电子超速报警系统就就是为了能够提高汽车运行的安全性,减少交通事故的发生,减少损失,保证驾驶人员的人身安全。

本设计从驾驶员自身安全角度出发,设计了一种检测车辆超速的报警系统。

该报警系统允许驾驶员通过自带键盘设置本车辆安全行驶的最高速度并通过LED数码管与其驱动芯片实现初显,当车辆处于行驶状态中,通过红外对管采集信号时刻监测机动车辆速度,通过单片机处理数据,最后对现时时速与初设时速进行比对,当发现车辆速度超过驾驶员设置的最高值时,蜂鸣器开始报警,提醒驾驶员减速。

在实时检测与自动控制的单片机应用系统中,单片机往往就是作为一个核心部件来使用。

此设计就就是一种基于51单片机对机动车超速行驶情况进行蜂鸣报警与灯光报警的系统。

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。
