| 摘 要： | 提出了一种基于CAN（controller areanetwork）总线的网络控制系统的分布式消息调度策略：该策略改变传统CAN节点消息的标识符固定分配的方法，它根据节点发送消息的时间紧急程度动态地给消息分配标识符，即与前一条消息的最大允许时间间隔较短且间隔中逝去时间较多的消息有较高的优先级。该文也对提出的调度策略进行了仿真分析。

| Abstract: | This paper presents a distributed message scheduling strategy of CAN bus-based network control system. This strategy changes fixed identifier allocation method of CAN data frame, dynamically allocates CAN identifier of data frame according to time urgency degree of message transmitted, the message whose residual time is short in time interval and whose maximum allowable time interval is short to preceding message has high priority. This paper also simulates the presented scheduling policy and analyzes it. |
