基于单片机汽车防盗报警系统设计与实现

摘要

介绍了一种新型的汽车防盗报警系统,以单片机为主控制模块,采用防震传感器以采集外部震动信号,利用声光报警模块发出声光报警,采用移动电话GSM拨打车主电话或给车主发短信,使用无线遥控模块可实现远程遥控开启与关闭系统。试验表明该系统可以实现在0~70 m开阔空地的远程准确的开启与关闭报警功能。%Introduce a new type vehicle anti-theft alarm system based on SCM as the main control module, the shock sensor collecting the external vibration signal, using the acousto-optic alarm module to send the acousto-optic alarm, using GSM to dial the telephone of owner or send text messages to owners, the use of wireless remote control module achieving remote control opening and closing system. The system has high reliability, simple peripheral circuit, strong practicability, low cost and so on.
