對工控系統中DCS操作站的選擇進行研究，發現采用UNIX平臺的DCS操作站在使用維護中存在缺點。對DCS操作站的使用現狀進行了調查分析，并將采用UNIX平臺的DCS操作站與采用Windows NT(2000)平臺的DCS操作站進行了對比，發現采用WindowsNT(2000)平臺的DCS操作站，能夠解決系統安全性與穩定性方面的問題，并給出了具體的改進措施。實踐證明:采用WindowsNT(2000)平臺的DCS操作站具有成本低、開放性強的優勢，是今后DCS操作站的發展方向。
關鍵詞:操作站 操作系統 安全穩定
Abstract: 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 maintenance. 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.
