基于USB數(shù)據(jù)采集模塊的QPC服務(wù)器設(shè)計
Design of OPC Server Based on USB Data Acquisition Module

摘 要 : 針對目前USB數(shù)據(jù)采集設(shè)備缺乏通用性驅(qū)動的現(xiàn)象，設(shè)計了基于USB數(shù)據(jù)采集模塊的OPC數(shù)據(jù)訪問服務(wù)器。該服務(wù)器采用 CO NT ROX工具包來開發(fā)，通過VisualC ++6 .0環(huán)境調(diào)用相關(guān)的OPC運行庫函數(shù)建立OPC服務(wù)器，同時由數(shù)據(jù)采集模塊提供的API 對設(shè)備中采集的數(shù)據(jù)進(jìn)行讀寫。該設(shè)計方法在朗肯循環(huán)蒸汽透平動力系練試驗臺上得到了驗證，并通過WebAcces，組態(tài)軟件連接所 建 立 的OPC服務(wù)器，實現(xiàn)對該試驗設(shè)備的本地和遠(yuǎn)程監(jiān)控。
