工控系统DCS操作站选择

The Selection for DCS Operator Station in Industrial Control System

对工控系统中DCS操作站的选择进行研究,发现采用UNIX平台的DCS操作站在使用维护中存在缺点。对DCS操作站的使用现状进行了调查分析,并将采用UNIX平台的DCS操作站与采用W indows NT(2000)平台的DCS操作站进行了对比,发现采用W in-dows NT(2000)平台的DCS操作站,能够解决系统安全性与稳定性方面的问题,并给出了具体的改进措施。实践证明:采用W indowsNT(2000)平台的DCS操作站具有成本低、开放性强的优势,是今后DCS操作站的发展方向。

Through researching the selection for DCS operator station in industrial control system, the disadvantages of DCS operator station based on UNIX platform are found in operation and maizttenanee. After investigating and analyzing current status of use for DCS operator station, two types of DCS operator stations based on UNIX and Windows NT（2000） were compared. It was found that the problems in security and stability could be resolved by using DCS operator station based on Windows NT（ 2000）, and concrete measures for improving were proposed. The practice proves the DCS operator station based on Windows NT（2000） is provided with low costs and features strong open characteristic. It is the developing trend of DCS operator station in future.
