針對煤礦井下高壓供電系統中開關保護裝置可操作性、可靠性差，測量、通信等方面的問題，設計出一種基于WinAC的高壓防爆開關保護測控系統。硬件系統設計以WinAC RTX為控制核心，運用Profibus現場總線進行控制結構設計，軟件開發以西門子公司的組態軟件WinCCV6.0 和Step7V5.2為平臺，設計了友好的人機界面和防爆開關測控功能。結果表明，該測控系統的實時操作系統，提高了系統的實時性和保護動作的靈敏度，具有強大而友好的人機交互界面，實現了集測量、控制、保護、通信等功能。

　　Abstract:

　　As for underground high voltage power supply system of the switch protection device operability， reliability， measurement， communications and other issues， the system of a high-voltage proof switch， protection and monitoring based on WinAC was designed. The WinAC RTX hardware designed as the control of the core， the control structure was set up with Profibus fieldbus， used Siemens configuration software WinCCV6.0 and Step7V5.2 as a software development platform， a friendly man-machine interface and explosion-proof switch monitoring control functions were developed. The results show that the control system’s real-time operating system improves the system’s real-time protection ability and sensitivity， has a strong and friendly man-machine interface， and achieves a set of measurement， control， protection， communication and other functions.
