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.
