摘　　要：为使汽车发生车祸时可在最短的时间内得到援救,以减少车祸伤亡,设计一种基于加速度的车祸报警系统。系统采用MMA7455三轴加速度传感器测量车辆的加速度,根据设定的加速度实现车祸状态的报警。一旦判断发生车祸事故,通过GSM将信息发送至已设置的手机号码,以便于及时救援。In order to get the rescue in the shortest possible time and reduce the casualties in the car accident, a car accident alarm system based on acceleration is designed. The system uses MMA7455 three-axis acceleration sensor to measure the car acceleration, and realizes the alarm of accident state according to the presupposed acceleration. In order to facilitate timely rescue, the system sends the messages to the presupposed phone number through the GSM board once the car accident occured.
