The Research Of Data Integrated Technique In Different Control Systems And Its Application

With the development of Web technique, a profound revolution is taken place in the control field. The control system develops in the direction of Intranet structure and has the feature of opening, which is the trend of control system. Therefore the integrated information system is appeared. During the realization of the system, the most important and difficult point is data integration in different control systems. The paper studies this topic deeply.Firstly, the functions and structures of integrated information system are discussed, based on which an integral description about this system is given. Secondly, the purposes and functions of data integration are interpreted. Thirdly, all kinds of solutions for the difficulties of data exchange and integration are proposed, which not only include the traditional technology, such as DDE,WinSock ,ODBC etc, also include the new technology —— OPC. In the following chapters, every technique is studied independently and systematically. To every technique, its principle and methods and steps of realization are analysed; according to the application and research, combined with typical control system, the specific application is demonstrated. On the base of them, the character of each technique and the place they fitted for is concluded.In the end of paper, a model of integration with many control system is proposed. On the basis of the structure of B/S/C and comprehensive application of many techniques talked about above, an integrated information system is preliminarily realized. Then, a management information system in an enterprise is successfully established by the application of the module. The system not only fulfils the need of manufacture in the factory but also brings good benefit after being put into production.
