摘要
CAN总线是现场总线的一种 ,较复杂的现场总线应该既能传送实时数据 ,又能传送非实时数据。针对实时数据和非实时数据的传送 ,分别提出了分布式优先权队列动态分配晋升机制和入侵型CSMA/CD协议 。
The controller area network is one of the field bus.A well-designed industrial field bus must be able to satisfy both RT and non-RT data exchange.At first this paper presents a distributed priority queue and its dynamic assigning promoting mechanism on CAN field bus;second the paper induces an intruding CSMA/CD protocol of the CAN fieldbus MAC layer.The problem of compatibility of both kind of transmission can be solved with it.
