在电子科技不断发展的同时，许多不法分子的盗窃技术也在提高，此时就需要我们对汽车防盗系统功能的改善加以重视。
该课题研究的内容是“基于单片机的汽车防盗系统设计”，该系统主要由单片机最小系统、人体感应电路、振动检测电路、GSM模块、控制电路以及声光报警电路组成。
该系统有三个报警状态，可以实现布防、撤防及SOS紧急呼救的三种切换功能。接入电源后，GSM开始搜寻手机信号，当车主离开驾驶座位后按下布防按键，绿灯亮，若检测到驾驶座位有人或车外部受到冲击时，启动声光报警，红灯亮起，同时发短信给车主，提醒车主注意。当车主在车上时可以将报警器设为撤防状态，以免误操作；当车主离开车辆时将报警系统设为布防状态，实现无人时的报警。

In the development of Electronic Science and technology, at the same time, many criminals steal technology is also improving, at this time we need to improve the car anti-theft system function to pay attention to.The content of the research is "based on single-chip microcomputer automobile anti-theft system design, this system mainly consists of the minimum system of the one chip computer, the human body induction circuit, a vibration detecting circuit, GSM module, control circuit and the sound and light alarm circuit.The system has three alarm state, can achieve three kinds of switching on / off alarms and SOS emergency call. Access to power, GSM began searching for mobile phone signal, when the owner left the driver"s seat after press the deployment of key, green light, if detected in the driving seat or car outside impact, start sound and light alarm, red light is on, also send text messages to the owners, to remind the owners attention. When the owners in the car can set the alarm for disarming state, to avoid misoperation; when the owner leaves the vehicle alarm system design for the deployment of state and realize unmanned alarm.
