摘要
针对传统手持式汽车故障诊断设备的不足,设计了基于智能手机的汽车远程故障诊断系统.该系统由诊断通信装置、智能手机客户端、远程故障诊断服务中心等部分组成,通过OBD、蓝牙和Socket实现诊断数据传输.利用网络技术优势,提供基于案例推理的远程智能诊断共享服务.试验结果表明:该系统平均诊断时间约30min,使用网络流量仅200KB,满足对汽车诊断技术的实时性和移动性的需求.
To overcome the shortcomings of traditional hand-held automotive diagnostic equipment, remote vehicle diagnostics system （RVDS） based on smart phone was designed. The system consists of diagnostic communication devices, smart phone client and remote diagnostic center. The diagnostic data transmission method through the OBD, Bluetooth and Socket was discussed in detail. And by using advantages of network technology, the case-based reasoning service was provided. The results of the experiment indicated that the proposed system needed only 30 min to diagnose and network traf- fic of 200 KB on the average. Therefore the system can satisfy automotive diagnosis technology for in- stantaneity and mobility.
