摘要
近年来,随着汽车产业的迅速发展和人们生活水平的不断提高,我国的汽车数量正逐年增加。同时汽车驾驶人员中非职业汽车驾驶人员的比例也逐年增加。并且随着人民生活水平的不断提高,私家车已经走入千家万户,成为主要的交通工具。然而,私家车主由于不是专业的司机,熟练程度、速度的感觉不是特别好,车速往往根据偏好,随意提速、超速行驶,当汽车处于超速行驶状态下,其稳定性与安全性大大降低,一旦出现紧急情况,往往会导致车毁人亡的重大交通事故发生。综上所述,有必要开发一套超速报警系统,辅助提醒驾驶员以达到控制车速的目的。

本系统从汽车行驶的安全角度出发,在不改变汽车原有结构的基础上,对汽车行驶的速度及其它车况参数进行采样、测量、计算,利用AT89S51型单片机对数据进行有效的分析,提高了系统对复杂路况处理能力。并且采用实时报警、延时控制等方法实现督促驾驶员在道路允许车速范围内安全行驶,从而实现超速报警、提高人车安全的重要功能。
在实际设计过程中,利用一个6V直流电动机串联电位器来模拟车轮的转速和线性加速,直观的展示了整个系统的运行过程。

ABSTRACT
In recent years, with the rapid development of auto industry and people living standard rise ceaselessly, the number of cars in China is increases year by year. While driving a car driving china-africa professional personnel has been increasing proportion of personnel. And as people living standard rise ceaselessly, cars had walked into the thousands, and e the main mode of transport. However, private owners because the driver is not a professional proficiency, speed, the feeling is not particularly good, speed often preferences, optional speed, according to a speeding, when car is in speeding state, its stability and security reduced greatly, once in an emergency, often leads to serious traffic accident the elderly. To sum up, it is necessary to develop a set of speeding alarm system, auxiliary remind drivers in order to achieve the purpose of controlling the speed.
The system of the car safety from Angle, not changing the car, on the basis of original structure to the speed of the automobile and other sampling, the measurement condition parameters, calculation of, use of the data type AT89S51 single-chip effective anal
