摘要
本文针对工业以太网时间确定性方面的缺陷,提出了一种时间触发以太网架构,通过改进通信协议栈的结构来改变以太网的媒体访问策略,从而大大提高了整个网络的时间确定性。工业现场的设备使用时间触发以太网互连,不但可以满足各任务时间精确性,而且可以使现场的设备和Internet上的任意主机进行通信。
This paper provides a time trigger architecture in industrial ethernet to overcome limitation of ethernet s time deterministic.By changing the architecture of communication protocol stack,the way of media access is changed,as a result,the time deterministic of whole network is remarkably improved.Using time trigger ethernet as the method of industrial device interconnection will satisfy all task s time accuracy,and will make sure that each industrial device can communicate with a host in Internet.
