OPC技術(shù)解決問題的方法
OPC是為使不同供應(yīng)廠商的設(shè)備和應(yīng)用程序之間的軟件接口標(biāo)準(zhǔn)化,以及使其問的數(shù)據(jù)交換更加簡單化而提出的。作為結(jié)果可向用戶提供不依賴于特定開發(fā)語言和開發(fā)環(huán)境的可以自由組合使用的過程控制軟件組件產(chǎn)品。利用OPC的系統(tǒng)由按照應(yīng)用程序(客戶程序)的要求提供數(shù)據(jù)采集服務(wù)的OPC服務(wù)器、使用OPC服務(wù)器所必需的OPC接口,以及接受服務(wù)的OPC應(yīng)用程序所構(gòu)成。OPC服務(wù)器按照各供應(yīng)廠商的硬件所開發(fā),因此可以吸收各供應(yīng)廠商硬件和系統(tǒng)的差異,從而實現(xiàn)不依賴于硬件的系統(tǒng)構(gòu)成。同時利用一種叫做Variant的數(shù)據(jù)類型,可以不依賴于硬件中同有的數(shù)據(jù)類型,按照應(yīng)用程序的要求提供數(shù)據(jù)格式。利用OPC 使接口標(biāo)準(zhǔn)化可以構(gòu)成如圖2所示的系統(tǒng)。
