Research on embedded vehicle diagnosis technology based on wireless network

Abstract

With the development of vehicle networking era, the application of wireless network technology to realize vehicle remote diagnosis has become the main research subject. This article designed a embedded diagnosis device. It transmits the vehicle information to a remote server by GPRS wireless network, and the remote server analyzes diagnostic data to estimate the vehicle state in real-time. The vehicle information will be stored to TF card when the wireless network was abnormal, and the data storage format is FAT32 file system. We have realized the miniaturization of diagnostic device by the design of hardware and software, and also realized vehicle remote diagnosis by GPRS wireless network in complex environment.
