| 摘 要： | 介绍采用CAN现场总线进行消息通信,让系统中的各智能节点同步,使分布式控制系统中所有节点拥有相同的时钟节拍,以便于整个系统能采用时间触发的软件系统,通过混合式调度方式,保证分布式系统中所有的任务分工协作,实时高效运行,避免因事件同时触发而产生冲突,而使某些任务被延时或忽略.

| Abstract: | A DCS for time-triggered based on CAN, which make all intelligent nodes own a same tick was introduced. A time-triggered operation for the whole system can be achieved by using the tick. The programming of mixed schedule for CAN based DCS was described. The mixed schedule makes all tasks were cooperated and executed efficiently. The schedule avoided the transmission collision. |
