| 摘 要： | 通过车载诊断系统(OBD)连接汽车的CAN总线,进行车辆数据实时采集,同时将采集到的数据进行处理.本文采用TDA61芯片和WiFi无线传输单元搭建两个模块电路,一路发送汽车状态信息,另一路接收所有CAN总线上传输的数据信息.该系统扩展了车载诊断系统的外部应用,应用的汽车协议为支持OBD II的CAN总线的ISO15765协议,收发的数据通过外接串口显示.结果显示,系统实现了汽车接口数据的采集和处理.

| Abstract: | The CAN bus is connected with the on-board diagnostic system (OBD),which collects the vehicle data and processes at the same time.Two road circuits are set up by adopting TDA61 chip and WiFi wireless transmission unit,one circuit sends the vehicle state information,the other one receives all the data information from the CAN bus.The system extends the on-board diagnosis system of the external application which supports the OBD II ISO15765 protocol of the CAN bus.The data can display through an external serial port. The experiment results show that the system realizes the vehicle data acquisition and processing. |
