摘要
为了解决汽车维修行业远程故障诊断问题,利用OBDII、GPRS和Internet等技术设计开发了汽车远程诊断系统,重点介绍安装在汽车上的远程诊断设备的电路原理图和嵌入式软件设计。汽车远程诊断系统实现了自动定时对汽车进行远程故障检测,尤其是跨地域的专家可以通过网络实现对汽车疑难杂症的会诊,从而减少了汽车的潜在故障,提高安全行驶风险的预警机制以及故障诊断的准确性和可靠性。
In order to solve the remote troubleshooting issues of automotive,designed and implemented an automotive remote diagnostic system based on OBDII,GPRS and Internet technologies.The circuit schematic and embedded software installed remote vehicle diagnostic equipment are the emphasis.The automotive remote diagnostic system will automatically check the car from time to time.Especially the experts from different place can use the system to analysis the problems of car together.So using the system can reduce the potential default of vehicle,accelerate the early warning mechanism,and improve the accuracy and reliability of the fault diagnosis.
