基于Android智能手机的汽车交通事故报警系统

The Alarm and Detection System of Car Accidents Based on an Android Smart Phone

基于Android平台智能手机开发的交通事故报警检测系统可在第一时间报警并发送报警短信给最近的联系人。阐述报警系统各个模块的工作原理,通过手机模拟器开发程序,实现用手机内部加速度传感器判断是否发生事故,通过GPS定位确定事故地点,通过GSM网发送报警信息。系统经Sensor Simulator的开源工具辅助调试,各模块均能够正常工作。

Developed from the smart phone based on the Android platform, the traffic accident warning and detecting system can issue a warning and send the warning message to the recent contact as soon as possible. This paper illustrates the working principles of different modules of the system. By mobile phone simulator developing programs, the system can judge whether a traffic accident occurs through an acceleration sensor inside the phone, identify the accident location by GPS, and issue a warning message through GSM. The modules function normally via the open source aided debugging of the Sensor Simulator.
