大型DCS系统中工业以太网通信协议的设计与应用

Design and application of the industrial Ethernet technique in large scale DCS

在分布式控制系统DCS(Distributed Control System)中,网络通信是骨架,对DCS系统十分重要。为了将传统的以太网技术应用于工业领域,提出一种工业以太网协议技术——DNet(Determinate Net Protocal)。DNet协议技术使得DCS网络通信中的数据传输满足工业控制的确定性、实时性、可靠性与安全性等要求。

The communication is the base of the DCS（Distributed Control System）.It is very important in DCS.One industrial Ethernet technique is investigated to apply the conventional ethernet technique into industry field.The industrial Ethernet technique is named DNet（Determinate Net Protocal）.The communication realizes the determination,real-time performance,reliability and security by DNet.
