The Design And Implementation Of The Graph Editor In Electronic Automation System

In recent years, the power monitoring of our country has been gradually from the traditional way of the scene monitoring into the automation monitoring. To provide the customers with the surveillance and control of electronic components over the display directly through the network has become one of the main functions of the electric automation monitoring system. Therefore, how to develop a set of graphics system which the staff can monitor more conveniently and safely, appear to be particularly urgent and necessary. The function of the graphics system which is an important component of the monitoring function is showing the system information through graphics, forms, multimedia, and some other ways, so the staff can make decisions after knowing the running state. And the graphics editor, the important component of the graphics system, is used to monitor the production and edit of graphics.The thesis carries on the detailed analysis to the requirements of the graphics system of electric automation control system. To the questions which be mentioned in the requirements, the thesis studies on related technology, and advises to adopt a solution which is based on .Net platform and MVC design pattern. Aiming at the issue of how the system can be extensible and maintainable on the design level, the thesis designs the software architecture of the graphics system, and completes the detailed design of the core components by the sequence of view, controller, model and system security. With the key technologies of local refresh, primitive edit and graph-model integration, it develops such a graphics system: which could provide a well GUI that users can protract and modify the power system wiring diagram conveniently; which could carry on the lamination management to the graphics; users can customize the use of the primitive equipment according to the scene demand; which could finish the power system computation parameters input and equipment elements modeling only with the operation of mouse on the wiring diagram; primitive parameters is stored in the database which has the versatility, including all information that the power system needs. Finally, design an electrics graphics edit system model which has a clear structure, extensibility, maintainability and reference value. Based on the requirement analysis and detailed design, the thesis realizes the key functions such as rapid refresh of the front view, the mouse visualization operation on the primitive, protract a wiring diagram using the graphics library and son on. It also realizes some other assistant functions such as model searching and document management. Through the verification of the system detailed design and implementation, the thesis gives a feasible power system graphics editor model and provides a solution, which has some reference value, to the design and implementation of user-defined primitive, visualization control primitive and no distortion variation primitive.
