摘要
针对车祸中乘车人员无法及时自救的问题,提出车祸自动定位报警的方法。系统主要包含车祸检测、地理位置读取、报警信息发送和车祸事故记录四个主要的功能模块。通过对安全气囊点火器的实时监测,并利用MPU6050传感器监测车祸的发生;借助GPS定位的功能,实时获取车祸发生位置;利用ISM与GSM模块完成近远程通信,向指定联系人或者交通事故救援平台发送求救信号;最后将事故发生位置进行记录,作为交管部门总结发布事故多发路段的依据之一。同时,考虑到车祸等级的不同,系统提供30 s延时报警提醒的功能,驾乘人员可以根据现场情况,对是否报警进行选择。通过模拟运行测试的结果,该设计具有灵敏度高、使用和维护成本低、方便推广的特点。
In view of the problem that the passengers in the car accident can not save themselves in time,the method of automatically locating and alarming the car accident is proposed.The system mainly includes four main functional modules:vehicle accident detection,geographical location reading,alarm information transmission and vehicle accident accident recording.Through the real-time monitoring of the airbag igniter,and using the MPU6050 sensor to monitor the occurrence of the car accident;using the GPS positioning function to obtain the location of the accident in real time;using the ISM and GSM modules to complete the near-distance communication,to the designated contact or traffic accident rescue platform Send a distress signal;finally record the location of the accident as one of the basis for the traffic control department to summarize and issue the accident-prone road section.At the same time,taking into account the different levels of the car accident,the system provides a 30 s delay alarm reminder function,the driver and passenger can choose whether to alarm according to the situation on the spot.By simulating the results of the running test,the design has the characteristics of high sensitivity,low use and maintenance cost,and convenient promotion.
