摘要
随着社会科技的进步、人民生活水平的提高和节能环保意识的增强，生活中的交通工具正在向污染少、能耗低的方向发展，而电动车正属于其中之一。电动车的环保、节能、轻便、成本低等特点，使它受到越来越多人的喜爱。而随着电动车的普及，它的防盗问题也越来越突出。为了更好地解决防盗问题，应用新技术来设计电动车防盗系统是非常必要。
本课题的主要内容是设计一个单片机控制的电动车防盗系统，该防盗系统采用单片机AT89S52作为整个系统的控制核心。该系统对于车主来说，是用遥控器控制电动车的布防、撤防和寻车三种状态，只有当按下撤防键后才能进一步启动电动车。防盗的功能是通过振动传感器模块检测电动车的异常振动信号，且把感应到的振动信号转换为电平信号，传递给单片机，通过程序判断是否报警，如果为报警信号，则利用GSM无线通信模块TC35向预设的车主手机发送报警短信，且通过扬声器发出警报声，以此来威慑不法分子，达到保护电动车的目的。而电动车的启动是通过语音来控制的，必须通过正确语音密码才能启动，因此能起到更高强度的防盗功效。
本课题设计的多功能电动车防盗系统与普通的防盗系统的不同之处在于，其能够在发出报警声的同时，利用GSM无线通信技术至车主手机，且利用语音识别技术来识别启动密码，进而启动电动车，
替换了使用钥匙启动的方式，使防盗效果达到更高的层次。

Abstract
With the advancement of social technology, the improve of people's living standards and the strengthen of energy-saving environmental protection awareness, the direction of life transport is less to pollution, low energy consumption, and the electric car is belong to one of them. The characteristics of the electric car are environmental protection, energy-saving, portable, low-cost and so on, and that make it popular in more and more people. But with the popularization of electric car, its anti-theft problem is also becoming more prominent. In order to solve the anti-theft problem, application of new technologies to design the electric car anti-theft system is necessary.
The main content of this topic is the design a electric car anti-theft system which controlled by a Single Chip Microcomputer, this electric car anti-theft system uses a AT89S52 MCU as the core of control in the whole system. To the owner of car, this system is using remote controller to change the three states of electric car in deploying defense ,cancel defense and search car, and then only press down the cancel defense button can you start the electric car . The function of the anti-theft system i
s detected the abnormal vibration signal by vibration transducers module,and then convert the vibration signal to level signal, finally, transport the level signal to the MCU and judge whether it is the warning signal. If it is the warning signal ,so send a warning message to the owner’s mobile phone by TC35 GSM wireless communication module, and make a warning sound through speakers, deter criminals by this way, achieve the purpose of protection the electric car. By the way, start the electric car by Speech Recognition, it is necessary to input a correct password to start it, so that, it can reached a higher level’s anti-theft.
The multi-function electric car anti-theft system of this project is difference from the ordinary anti-theft system, it can make a warning sound and at the same time send a warning message to the owner’s mobile phone by TC35 GSM wireless communication module, also it use the voice recognition technology to identify password, then start the the electric car, it take the place of the key, make the anti-theft to achieve a higher level.
Key word: electric car; anti-theft system; transducers; warning signal
