摘要
采用AT89S52作为控制器,连接并控制自主设计的超声波倒车雷达的接收与发送模块。控制器将倒车雷达模块的数据以LIN协议规定的报文格式发送到LIN总线,通信过程按照LIN协议规定的一主多从的通信方式。实验表明,该系统数据的传输符合LIN协议标准,能够很好地与其他符合LIN标准的汽车电子设备进行通信,具有较好的实际应用价值。
The design used the AT89S52 as its controller, which is connected to the independent research ultrasonic reversing radar system with the receiving and sending models. The controller sends the data from reversing system to LIN bus which is based on the message of the LIN protocal. In the system＇s communicating process, the communication model is based on the one master and some slavers which is based on the LIN protocal. The test certify that the system data transmission comply with the LIN bus protocal, and it can communicate with another automotive electronics which are designed on the LIN bus protocal, and there is highly practical application value.
