为了准确地检测出车辆的被盗情况,并迅速向用户报警,文中研究了一种基于MEMS三轴向加速度传感器的车辆运动状态检测技术,并提出了基于此技术的防盗终端和报警系统设计方案.论文首先介绍了防盗报警系统的结构,然后对采集到的加速度数据进行分级处理,分别根据加速度的变化情况及加速度幅度概率值的规律来判断车辆的运动状态,通过设定合理的门限值,完成对车辆非法运动的判定,并触发无线通信模块向用户报警.对配置防盗终端的汽车进行了多次模拟被盗实验,成功报警率达到98%.实验证明,算法简便快捷,实时性好,准确率高.

In order to accurately detect and quickly alarm to users when the vehicle was stolen,study a kind of vehicle motion state detec-tion technology based on MEMS three axial acceleration sensor,and put forward guard against theft terminal and alarm system design scheme based on the technology. First introduce the alarm system structure,and then do classification processing to the collected accelera-tion data. Respectively according to the change of acceleration and acceleration amplitude probability value judge the law of vehicle mo-tion state. Through setting reasonable threshold value complete the decision of illegal vehicle movement,and trigger the wireless commu-nication module alarm to users. The car with security terminal configuration has carried on simulation stolen experiment many times,suc-cessful alarm rate reached 98 percent. Experimental results prove that the algorithm is simple and direct,good real-time and high accuracy.
