The computer technology's rapid development has greatly accelerated the advance of information society pace. Computer technology has been widely applied in the large-scale enterprises, and the GIS as an important computer technology continues to introduce new data has become a new technology wave after networked storage, it will transfer storage into graphics of the era of digital . Daqing Oil Field as a large state-owned enterprises, involving a considerable range of professional face, producing a wide range of categories of data, a variety of graphical information classification number. For example: The power system graphics, tables, and text materials as the most commonly used information is stored in oil field work, as the oil companies showed an exponential increase in development, how to combine the power system's graphics data and attribute data, establish the graphics database to form a diversified graphic database system, realize the internal properties table of graphical database connected with the attributes database, store process and analysis the graphic data and attribute data, solve the problem of existing electric power system's no data or no map , establish a modern model of the advanced data management database has become an important issue.The paper's main task is to combine the geographical line of power system characteristics, using the geographic information technology and the load line to establish the corresponding graphical database and properties databases, so the power data management system changes from simple static information into dynamic graphics and the form of databases, establishing the graphics data and attribute data through the pixel corresponding to the relationship between the establishment of internal labeling, realizing the internal properties of graphical database tables and attributes in the attribute table database connectivity, graphical data will be unified with the attribute data storage, processing and analysis as the three tasks.1. Establishing the vector graphics storage model. In the power system.. GIS systems are generally stored in a stratified approach such as spatial information is divided into numerous thematic layers, and then carried out on these thematic layers of spatial analysis of the corresponding operation. In this paper, using power system based on graphics to process the vector graphics and establish the conductor, insulator, surge arresters, capacitors, falling insurance of the model based on vector data, users can maintain the power pole, transformer, load switch, circuit breakers , such as power lines across the pixel to lay. GEOMEDIA the characteristics of GIS data is the foundation of the storage pattern graphics to point, line, regional basis. Combining the power needs of graphics operations, the completion of the foundation of the vector graphics model of the design of storage, has established the border, stop the Treasury, oil wells, power based on pixel storage model, according to 19 categories.In the process of designing the model, we have completed the management of meta-data specification. The system development process graphics needed to create a new element of information, displayed in the graphics area, the symbol corresponds to the load line (including all kinds of mast, transformers, circuit breakers, etc.), these symbols is no uniform standard norms, after discussions, the introduction of the symbols Microstation to create software, based on user demand for different load-line graph with a standardized alternative symbol logo, graphic database system as a power symbol reference standards, a unified symbol set.2. Establish the power graphical operating system. . Research visualization information system of point, line, surface, graphics and professional attributes GIS mapping software, providing mapping and management capabilities and professional graphics software features of lines, load lines and other graphic elements with the characteristics of map graphics power that the professional software can not be achieved . Realizing synchronization updating with the small lines graphic and large line graphic in due to solve the small map and large map can not be synchronized with the operation, achievement of a text message graphics and interactive information, that is, to achieve the purpose of investigation that is used to provide map and data display functions at the same time, providing effective solution to map data out of touch with the problems.Graphical operating systems need to map attributes, geographical coordinates, location information such as query layer management, drawing line segment management, creation and management elements, the text of the creation and management functions. Using the function of the system, designing and creating graphics database and attribute database, graphics, database graphics data storage entities and entities closely related to the attribute data, attribute data is stored dynamic data and statements, attribute information such as text, graphics, database and attribute database independent of each other. At the same time, in the graphics metafile database attribute table to establish a connection number, will be the perfect combination of both to achieve the graphics data and attribute data of the interactive application.3. Establishing a paper system combination with graphics. Establishing a standardized system of instruments so that the line power system maintenance, line maintenance, line construction work, such as power management and line management can combine with graphics. Ensuring graphics data to timely updates with the power data sharing, significantly improve power management. Paper management system functions and data lines is closely related to the role of various types of instruments are the main lines for every repair, maintenance, construction and other operations, involved in and influence on the production equipment, units, statistics show that residents of the information, the Working staff review of the information, work order confirmation notice to ensure that in-line inspection, maintenance, operation and construction of the normal oil production. Combination of the line power system maintenance, line maintenance, line construction work, such as power management, in the graphics database on the basis of the extracted directly from the database of dynamic data, line data in real-time updates when changes occur attribute data to ensure the road map data and attribute data of the same power system to establish a standardized reporting system.Through the research of the subject , realized the power of access to vector graphics, data visualization of information, the establishment of the graphics database, formed a diversified graphic database system to solve the problem of existing electric power system's no data or no map, it is a model of modern data management database management system. Realized the systematic, modular and effective graphical data management power system, Improved the efficiency of power management Create a new trail for power system information management.
