摘 要
 
 随着科技的发展，汽车是越来越安全了，但是窃车贼的手段也是越来越高明了。防盗车窗还是能被打破，电子锁照样能被撬开，也就是汽车盗窃的物理途径不能被完全切断。我们可以想象这样一个窃车的场景：汽车先被拖到一个偏僻的角落（异常移动），接着车窗或者车门被强力打开（异常的振动和震动），随后汽车就被盗走了。于是我们想如何在这些异常情况发生时，能自动的被快速、准确的检测到，同时快速、有效的报警呢？
 本设计是为了解决传统汽车防盗方式的缺点和不足而开发一种崭新的集成传感、控制和报警三大功能模块的汽车防盗GSM 报警系统，通过安装该报警器在汽车中，当传感器收到汽车震动、移动信号时，以GSM 网络为信道，把报警信息通过短信/电话通知用户，从而实现准确、实时的报警效果

Abstract
 Along with the technical development, the automobile was more and more safe, but stole Che Zei the method also is more and more wise The security glass can break, the electron locks can pry open in the same old way, also is the physical way which the automobile steals cannot shut off completely .Our conceivable such steals the vehicle the scene: The automobile is towed first (exceptionally moves) to a remote quoin, then the glass or the vehicle door are turned on by the force (unusual vibration and vibration), afterwards the automobile is robbed. How therefore do we want occurs when these unusual situations, can automatic by fast, the accurate examination, simultaneously is fast effectively, reports to the police? 
     This design is in order to solve the traditional automobile security way shortcoming and insufficient develops one kind of brand-new integrated sensing, controls and reports to the police three big function module automobile security GSM alarm system, through installs this alarm apparatus in the automobile, when the sensor receives the automobile vibrates, the motion signal, take the GSM network as the channel, reports to the police the information through the short note/telephone message user, thus realizes accurately, real-time reports to the police the effect

 Keywords：electron locks  alarm apparatus  automobile vibrates  motion signal
