摘　　要：随着生活水平的提高,国内外汽车数量在不断地增长,同时也带来了一系列的交通安全问题。当车辆发生侧翻或者碰撞的时候,驾驶员极有可能失去意识或无法脱身,导致不能在第一时间报警,失去了最佳救援时间。因此,本文提出了一种基于GPRS和车载导航仪的汽车紧急呼救系统,在车辆发生严重事故时会触发安全气囊打开,因此通过捕捉安全气囊点火信号可以瞬间获取车载导航仪的定位数据,并且进行截图以便更直白地获取地理位置。然后通过GPRS模块自动向交警等部门发出求救信号。同时驾驶员也可手动取消,避免了紧急刹车或其他因素导致的误触发信号。该系统最大的优点在于运用了车载导航仪,无需再另外配备GPS模块,实现了行车导航与紧急呼救一体化[1]。With the improvement of living standards, car number continues to grow at home and abroad.At the same time also brought a series of traffic security problems. When the vehicle rollover or collision, the driver may lose consciousness or can＇ t get away, so they can＇ t at the first time report to the police, and lost the best rescue time and cause serious consequences. Therefore, this paper proposes a vehicle emergency call system based on GPRS and vehicle navigation,when a serious accident happen ,the airbag will be triggered. By capturing airbag ignition signal can be instantly get on-board navigation positioning data, and a screenshot so that more straightforward for geographic location. And then automatically by the GPRS module to the traffic police department sent a distress signal. At the same time, the driver can manually cancel, to avoid the emergency brake or other factors lead to the trigger signal. The biggest advantage is that use of vehicle navigation system, no need to additionally equipped with GPS module, implementation of integrated vehicle navigation and emergency call.
