Application And Study Of Web Technique Used In Long-distance Supervision

Along with the development of computer and network technique, more and more department begins to do their jobs with computer and network. Especially, the fields of network expand continuously. This paper treat of computer remote monitors.As an important technique in industry field, monitor technique has come into being for a long time. The subject, <> , is made to strengthen the monitor of the eight pump stations in wuhan town and suburb. Accordingly, it can improve the efficiency of direction.The subject programming adopt OOP technique. High efficiency is one of the main advantages. Encapsulation technique saved time for programmer and reduced the difficulty of programming. Code reuse avoids the repetition of programming and predigests maintenance of code. Component technique makes it conveniently to take advantage of the 3rd party components. All above improved the efficiency of software producing.COM is an object based C/S model put out by Microsoft.it used to realize the reciprocity among software modules or applications. Delphi supplied COM object wizard and corresponding class define and interface. Delphi can integral COM on Windows expediently so as to realize COM based application.DCOM is an expansion of COM. It sustains distributing process entirely.As a main technique commended by Microsoft, ActiveX is discussed in this article. There are many conveniences to create ActiveX components with Delphi. One can create an ActiveForm, then put some components on it to achieve each function. In this way, the whole ActiveForm together with all its components can be a single ActiveX component. Since that ActiveForm can embed in IE directly. It often contributes to create Internet applications.Microsoft Transaction Server, for short, MTS is an object basedtransaction management system. It used to establish, config or manage Server application. MTS introduces a new programme environment former, which is an expansion of Microsoft standard COM.Active Data Object (ADO) is an application interface. It permit programmer to write application to access OLE DB data source, including ODBC.The subject integrated SQL Server 2000 database management system. SQL Server 2000 can word in many kinds of environment. It includes multilevel database systems and Desktop database system.At last, through the design and realize of Wuhan's drain pumpingstation data-collection and remote monitor system. It discusses the method and steps of how to establish a real application. In addition, it gives serval effect chart of the system.
