基于MMA7260的新型汽车防盗报警系统

Automobile supervising system based on MMA7260 sensor

针对目前汽车防盗报警系统存在的误报、不能检测静态倾角和接口电路复杂等不足,采用MMA7260加速度传感器,结合GSM通信、GPS定位技术,设计并完成了一种新型的汽车防盗报警系统.实验结果表明,基于加权平均方法的系统软件执行效率高,可以准确地检测出包括整车拖运在内的盗窃信息,有效地避免了声波和车辆经过造成的误报,同时实现了车辆状态监控、跟踪定位和车载通信系统.

To detect obliquity, and avoid misinformation, perplexing interface circuit existing in automobile supervising system, a new supervising system based on MMA7260 sensor is designed, which combined with GSM and GPS techniques. Results of experiment show that the software based on welghred average goes efficiently, can detect the theft information of car haul exactly without misinformation. At same time, vehicle monitoring and controlling, tracing and locating and car phone communication system are actualized.
