| 摘 要： | 为解决一个总线回路中不同类型设备通信的性能和效率问题,提出一种采用IEEE 1394总线协议和虚拟复合MAC(Media Access Control)的工业现场总线协议.在IEEE 1394基本协议层的基础上设计虚拟MAC子层,通过附加总线配置实现节点功能的区分,利用等时数据传输和异步数据传输实现时分多址、仲裁、轮询、令牌等MAC方式的数据通信.

| Abstract: | In order to solve the performance and efficiency problem in a bus system with different types of devices, a new virtual multi MAC(media access control) supported industrial fieldbus protocol was presented based on IEEE 1394. A virtual MAC sublayer on the IEEE 1394 protocol layers was designed. An additional procedure was needed to configure nodes' MAC functions. Using the isochronous and asynchronous channels the communication based on TDMA, arbitration, polling, and token passing was supported. |
