Power grid planning GIS graphic information acquisition and joining system based on TCP-IP

Abstract

The invention discloses a power grid planning GIS graphic information acquisition and joining system based on a TCP-IP. The system comprises a server arranged in a province-and-city network, and drawing clients arranged on PCs of users of all levels. The system also comprises: a planning GIS graphic basic data management module which is accessed, according to an external system database, to province and prefecture-level power grid spatial data to complete basic data generation and service data fusion; a power grid planning GIS graph drawing tool module which performs map basic operations and planning graphic vector data operations; and a province / city data acquisition and joining module which carries out data acquisition, broadcasting and updating operations for province / city drawing terminal operation information. The system has the advantages of informatization, automation and intelligentization. Power grid GIS graph drawing standards in a whole province are unified, unified management and control of power grid planning GIS graphics is enhanced, and the power grid GIS graphic drawing efficiency and quality is improved.

Description

technical field [0001] The invention relates to a combination of GIS spatial data storage technology and TCP-IP network transmission protocol to standardize the collection, forwarding, storage and broadcasting of the operation records of planning GIS graphics by users at all levels, so as to realize the planning of multi-user power grids in various administrative regions Independent drawing of GIS graphics, automatic collection of spatial planning information, and automatic stitching system of graphics in various regions. Background technique [0002] The power grid planning graphics can visually display the grid structure of the future power grid, the planning scheme of each project, the system connection situation, the substation site, and the geography of the line by laying the grid planning vector diagram on the basis of the image map and the vector map. Functions such as distribution status, comparison between the current power grid and the future power grid play a pivo...

Problems solved by technology

Through GIS technology, it is possible to efficiently access spatial data, query and manage spatial data, release and display graphics in layers, highly integrate vector graphics and business information, query and locate spatial information, and analyze spatial relationships and topological relationships. and other applications have greatly improved the informatization level of grid planning graphics management, and greatly improved the management capabilities of grid planning graphics in terms of data storage and application. However, the collection and planning of spatial information change operation information in a multi-user environment In terms of splicing of drawing results, traditional GIS software uses version control at the stored data level. Too fine control granularity makes it difficult to integrate with business, high technical requirements for users, and large amount of redundant data, which affects the realization of actual requirements for power grid planning graphics. , it is necessary to adapt the granularity of business requirements and the granularity of GIS data versions, and finally realize the collection and splicing of GIS graphics for power grid planning
