摘要
介绍了CAN总线消息的传输机制和优先级的分配方法。在分析固定优先级抢占式任务调度基础上,研究理想CAN中固定优先级非抢占式消息调度,讨论了总线节点中信号组合方法对消息调度的影响。
The article introduces the transmission mechanism and priority assignment method of the message on CAN bus .Based on the analysis of preemptive fixed-priority task scheduling, it investigates the non-preemptive fixed-priority message scheduling of ideal CAN .It discusses the affect on the combination methods of signals on the CAN node to the message scheduling.
