Digital program exchange system is one of the most important devices in power industry 數字程控調度交換系統是電力系統中重要的通訊設備。
The program exchanges data with the system of metasys in the mode of vb - dde - metasys . and it has fine operating interface 該軟件操作界面良好,通過vb ? dde ? metasys的模式與metasys系統軟件實現了數據交換。
Network can widen the method of program exchange , avoid repeat operate , ameliorate the mode of program communion and improve the av technique quality 因此,網絡化可以避免重復操作,改進節目交流的方式,并提高最終的視音頻技術質量。
At present , there are all kinds of digital program exchange systems , but these devices are of the following faults : 1 relatively short propagation distance 目前,數字程控調度交換系統雖然品牌眾多,但都具有如下特點: 1調度平臺發出的信號傳輸距離短。
It defines an open industrial interface based primarily on the component object model ( com ) technology that provides interoperability between disparate field devices , automation / control , and business systems . opc firstly is a kind of technology by which application programs exchange their data Opc的設計目的是利用微軟的com ( componentobjectmodel ) 、 dcom ( distributedcom )和ole ( objectlinkingandembedding )技術,開發一個開放的接口標準,為現場設備、自動控制應用和企業管理應用之間提供高度的互操作性。
