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 .笔者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 ,解决了两种数据在 CAN总线上传输的兼容问题 .
The controller area network is one of the field buses. A well-designed industrial field bus must be able to satisfy both RT and non-RT data exchange. This paper first presents a distributed priority queue and its dynamic assigning promoting mechanism on CAN field bus; and then induces an intruding CSMA/CD protocol of the CAN fieldbus MAC layer! The problem of compatibility of both leincls of transmission can be solved with it.
