摘要
在传统汽车故障诊断技术基础上,提出了一种基于GPRS和CAN总线的数据通信系统,并开发了相应CAN应用层协议、CAN网络通信以及GPRS网络数据传输等关键技术内容。该通信系统为汽车故障诊断提供了资源共享的便利途径。
This article is based on the traditional vehicle fault diagnosis technology,and a data communication system based on GPRS and CAN bus is proposed.We have developed some key technical contents,such as CAN application layer protocol,CAN network communication and GPRS network data transmission.The communication system provides a convenient way for resource sharing for automobile fault diagnosis.
