摘要
在机载通信系统中,将各个通信设备视为独立节点,通过CAN总线进行信息交换,有利于提高通信系统的可靠性与实时性,减少电气连线的复杂性。提出了一种基于CAN2.0B的应用层协议设计方法,详细介绍了协议中报文格式的分配、大数据量的分段传输以及节点间的通信方式。通过仿真测试,验证了应用层协议设计的可行性。
In some airborne communication system, data exchange between different airborne devices was realized by using CAN2.0B （Controller Area Network） protocol to minimize complexity of electric connection and improve reliability and real-time performance. The message format assignment, transmission of large amount of data and data exchange mechanism were also introduced in detail. Finally, an application example was proposed to confirm the feasibility of the proposed protocol design.
