摘　　要：实现了符合OBD-II车载诊断标准的诊断仪,车主可以利用手机蓝牙连接到该诊断仪,来实时监控车辆行车数据和故障信息,保障了行车安全。同时该诊断仪方便了车辆的维护和维修,汽修人员在汽车出现故障时,无需像以往一样携带专门的诊断设备,只需利用手机蓝牙连接到该诊断仪便可以读取车辆内部故障信息,及时定位故障,检修车辆。更进一步如果汽修人员自身经验不足,还可以通过手机把车辆故障数据上传到远程服务器,寻求4S店或汽修厂更加专业和老练的技术专家的协助。该诊断仪通过K、CAN总线与车辆内部ECU通信,通信协议采取ISO15765和KWP2000可以适配市场上大部分车型。This paper realizes the diagnostor in accordance with the OBD-II vehicle diagnosis Standard,the driver can use the Bluetooth to connect to the diagnostor,to monitor the cars's data and fault information in real time,ensured the traffic safety.At the same time,the diagnostor also greatly facilitates the maintenance of vehicles,because the maintenance personnel don't need to carry a special diagnostic equipment as before,they can just use mobile phone connected to the diagnostor with Bluetooth then to read the vehicle internal fault information to repair the vehicles.
