Design And Implementation Of Basic Geographic Information System For Chongqing Distrivution Network

The grid geographic of Chongqing information system is based on the geographic information system(GIS) technology, in order to meet the normal operation and development of the national grid for the safe operation of the power industry, management and maintenance, and management activities for the purpose. Power industry and computer technology combined with contemporary research. Before the power GIS systems are often based on a shared data structure in the form of documents, which makes the cost is very high, the operation is very complex.Therefore, this paper around the grid and extend the application of geographic information systems to distribution network information system software development as the goal, focus on geographic information and explore aspects of power shortage, and cited the huge geographic information system in the management of the distribution network advantage, while GIS platform and many domestic and foreign manufacturers were compared and studied by modern computer technology and GIS, the establishment of a distribution network for the geographic data model, while drawing a distribution network GIS software architecture chart, and ultimately the unified management of spatial data and attribute data.This paper proposes a new Web geographic information system of power grid development plan, the use of three-tier system framework of B/S mode structure, use of space database Oracle Spatial to save the geographic data, and study the new technology of Spatial data modeling method, using Microsoft Visual Studio2005 development tools based on Asp.net and ADO.net technology, developed with c + + language system management module, the map management module, graphic editor module, equipment management module and statistical query module to essential component system function module, eventually developed in chongqing power grid based geographic information system, and has set up a well in operation. The final results show that the power of GIS based on Web has such as lower cost, simplified operation, make full use of the advantages of resources, has won the acceptance of the customer unit...
