Satellite CAN bus network application protocol implementation system

The invention provides a satellite CAN bus network application protocol implementation system, which comprises a CAN bus message frame, a CAN bus message packet and a data communication module, the CAN bus message frame is a minimum unit of a bus message and is determined by a CAN bus link layer; the CAN bus message packet is a data packet composed of a single-frame message frame or multiple-frame message frames; and the data communication module stipulates a single-node communication flow and a multi-node communication flow of the CAN bus. According to the method, the reliability of the message packet data is ensured, the bus message processing difficulty is simplified, and the CAN bus safety and reliability in a satellite application scene are improved. 本发明提供了一种卫星CAN总线网络应用协议实现系统，包括：CAN总线消息帧、CAN总线消息包和数据通信模块；所述CAN总线消息帧为总线消息的最小单元，由CAN总线链路层决定；所述CAN总线消息包为由单帧消息帧或多帧消息帧组成的数据包；所述数据通信模块规定CAN总线单、多节点的通信流程。本发明保证了消息包数据可靠性，简化了总线消息处理难度，提高了卫星应用场景下的CAN总线安全性、可靠性。
