Distribution Network GIS System Technology Scheme One. Introduction The city distribution network directly facing the users, the tie contact with power users and power users. At the same time, it has the characteristics of complex wiring, large amount of data, and frequent changes. With the improvement of the quality of social economy and people's living standards, the power supply reliability, power quality and service quality have put forward increasingly high requirements, and the distribution network management information system has put forward higher requirements. Shantou Hongjing Technology Co., Ltd. proposes a solution for the distribution network GIS system, and closes the distribution network operation management, equipment management and security management, and push the application of geographic information systems into a new level.
two. Design ideological distribution network management involves various types of information, including geographic information, device information, operation information, user information, etc., which makes information on the distribution network, expressed in the form of the figure, so that the layer of the distribution network is formed. Space, layers all kinds of information, reflect on different layers, easy to hinder the information of the distribution network, hierarchically, and implement the dynamic combination of the layer. three. Technical features are integrated with advanced geographic information system technology as the starting point, integrating network communication, database, geographic information, etc., constitutes a distribution network GIS system with modern management features. The system implements a large database and the MapInfo geographic information platform. All distribution network information stores in a large database, and the database belongs to the MapInfo only stores some basic attribute information of the distribution network device and the user. Link the large database and MapInfo table data. Access to data and manipulate the OLE automation server interface technology of MapInfo. With the development of network and Internet technology, the geographic information system in the Internet or intranet environment can realize the distributed storage of geographic information, the release of spatial information, the address query, and the map display in the Internet environment, which is currently in the GIS field. The latest hotspot field. For the application of the distribution network, the system considers the future extension ability, reserved MapInfo's MapXtreme development technology to upgrade to an enterprise-shared distribution network GIS application system when needed. four. The operation interface of the system function system is intuitive, with powerful drawing function. Maintenance of graphics, data maintenance is very convenient, and the information of each subsystem has correlation and mapping. The user can perform an increase in system attribute data while maintaining the graphics, and can also be entered on the existing graphics.
The system has full open configuration, map operation, and map tool function. The full open system configuration includes: a full-scale line model, supports user-defined device types, supports user-defined account data properties, and map operation has layer stable scaling, graphics display "eye-catching" function. You can browse, query, statistical devices, and security attribute data on the distribution network. The operating state of various equipment can be visually displayed on the map. Fives. Applications The system can be successfully applied to the distribution network management of all power supply companies, and can also be used in the management of urban planning roads and underground pipe networks.
