OSEK直接网络管理消息算法的研究

Research on Message Algorithm of OSEK Direct Network Management Based on CAN-Bus

通过分析基于CAN总线的OSEK直接网络管理模式,提出一种OSEK直接网络管理的Ring、Alive消息算法实现方案。这种算法满足OSEKNM标准对网络管理消息的要求,并且简单易于实现。同时解析了网络消息的帧格式映射过程,包括网络管理消息在CAN总线系统上的帧格式等。

This paper analyses the mode of OSEK direct network management based on CAN- Bus, and designs algorithm implement of Ring message and alive message in OSEK direct network management. This algorithm satisfies the requirement of network management message in OSEKNM specification, and it is easy to be implemented. At the meanwhile, discusses the frame mapping of the network message is discussed, including the relevant frame form of network management in CAN- Bus system.
