摘要
为解决传统汽车故障诊断资源共享难、易受地理位置限制等问题,文章针对汽车现有车辆的诊断功能和诊断协议,研究了基于B/S架构的汽车远程诊断系统。根据汽车故障诊断协议特征,结合因特网传输特性,设计了诊断服务器和车载终端间的数据传输通信协议,据此对车载终端和服务器进行了详细设计。系统基于平台无关性设计思想,通过采用诊断协议通信参数动态配置策略,可应用于不同厂家的不同车型。测试结果表明,本系统能够很好的满足车辆远程故障诊断的要求,诊断信息反馈及时准确。
To solve the problems such as the difficulty of resource sharing and the limitation of geographical location of traditional vehicle fault diagnosis,a remote vehicle diagnosis system based on B/S architecture is studied in view of the existing vehicle diagnostic function and protocol.According to the characteristics of vehicle fault diagnostic protocol as well as the characteristics of Internet transmission,the data transmission protocol between the diagnosis server and the vehicle terminal is designed.On this basis,the vehicle terminal and the server are designed.Based on the idea of platform independent design,the system can be applied to different models of different manufacturers by adopting the dynamic configuration strategy of communication parameters of the diagnostic protocol.The tests results indicate that the system satisfies the requirements of remote vehicle fault diagnosis,and can get the timely and accurate feedback of the diagnosis information.
