The Study Of Graphic Database Integration Support Environmental In Dispatcher Training System

According to the equipment-oriented modeling approach, this paper designed a set of graphical database integration DTS supporting environment. The system established the equipment model and its topology structure through the equipment graphic element. At the same time, the databases ate created, and dynamic graphic elements and database automatically are bound, as well as the model parameters and record tools of equipment graphic element follow the structure of the record automatically. An object-oriented visualization technology is adopted in order to make it more humane when protracting the graphic and inputting data. So the users are in the face of the intuitionist graphic or dialog box, and then the cumbersome data is avoided. When the equipment graphic element is built, the database records are superadded automatically so that a one-to-one parallelism is realized between database and graphics. In this way, we can achieve graphics and database synchronization, and database and graphics can also be achieved synchronization, then a graphics interface system condition can be reflected truly. This system provided a better tool for the dispatcher training because its graphics can be refreshed fast and called flexibly.
