Design of vehicle rescue information interaction system based on embedded technology

In order to make sure the injured person can get rescue without delay, A vehicle rescuing information interaction system was designed, which consists of two parts, vehicle embedded system and rescue center terminal. This system works on a core control chip S3C2440. It uses GPS technology to let the Latitude and Longitude information about a car is acquired, to monitor a moving car's angular speed and accelerated speed by tori axial acceleration sensor. It also uses the Kalman filtering algorithm to do the data fusion, to get the vehicle pitch angle, roll angles and attitude 3D modeling display. We can get the conclusion from the comprehensive test and simulation experiment results. It turns out that the system has a well stabled interactive performance, it can improve the efficiency while rescuing the vehicle and injured people. It has a certain practical meaning.
