摘要
简要介绍了DCS及其网络在火电厂的重要地位,比较了HS2000控制系统DCS网络结构与MACSⅡ控制系统DCS网络结构的不同,分别对采用远程总线技术、服务器、交换机替代集线器、屏蔽双绞线替代非屏蔽双绞线等方面对DCS网络结构的改进进行了分析,对改进后的效果在下载速率、控制站网络故障、系统网重发和信息丢失等方面进行了验证。
The Distributed Control System （DCS） and its network are presented. A comparison is made between HS2000 control system network and MACS Ⅱ control system network. The effect of DCS network retrofitting is analyzed. Results show the improvement in download speed, the control station network faults, the system network uttering again and information .losing tirines , etc.
