Figure Walking Routes Diameter System Design And Research

With the development of computer technology and graphics technology, Graphics technology is used more and more widely in engineering application, more and more deeply, Graphic way is more intuitive, high communication efficiency than words, language, oral communication, it is also a way that is the present domestic workers willing to accept.Graphic communication way are reflected in all walks of life, such as the world map, map of China, the city map, administrative map, traffic map, transmission line work area path diagram, building electrical engineering drawing, the railway circuit diagram and so on.For power, construction enterprises, transmission line work area path diagram, secondary wiring diagram, building electrical engineering diagrams, circuit diagram and so on,all kinds of graphics system brings great convenience to the enterprise.So, similar to the figure walking routes diameter system is the graphics is an important subject in the graphical information construction, the purpose is to make full use of existing computer software and hardware resources and other business information system data in order to make up for the inadequacy of traditional manual communication.Compared with the traditional mode (close to information, the large number of information, people identify similar text information with the naked eye, error prone), Information graphically on data is easy to distinguish, also let a person have the feeling of its borders, namely the simulation reality. It has very important practical significance, in the process of modernization of graphical data.And figure walking routes diameter system is to solve the problem and the development of the project. Power line walk path diagram is with the aid of computer and the analysis software of electrical engineering, calculation and simulation, drawing and the modern design technology of the document.Based on the above understanding, this topic from the following aspects were studied:First,for graphics software at home and abroad are learning and research, analyzed the function of each software, and the value of each system to the user, Used for each of the software technology, namely, from a perspective of the whole system of technology and consider the value of the project, friendliness, etc, are studied, and according to the characteristics of the system (graphics need high efficiency, etc), and finally chose VC++and SQL Sever2005.Next, after determining the technology for the VC++, the single document (SDI) model in VC++development, the use of menus, status bar, the toolbar, device context (DC), how to draw the basic graphics, graphical interface (GDI) object, object serialization, database access technology etc, study, as well as the above technical problems existing in the actual users in a graphics program are studied, in the study of the above technology, have made a small example respectively, to improve the development efficiency of late.Finally, on line walk path diagram and graphics system for the research. And eventually decided to adopt the way of file save primitives, graphics, primitive custom, graphics corresponding data read from the database of ideas to complete the project.This topic design system users can make power bureau for any custom primitives,can also according to the custom primitives for graphics rendering,once the user can also according to the custom uniform figure yuan for graphics rendering, And in figure yuan changes, primitive automatically replaced. At the same time, electricity users can connect each power substation graph are merged into general users.
