Abstract

The invention provides a power grid device and facility information providing method and device to solve the problem of low information retrieval operation efficiency in fuzzy query in a power grid geographic information system (GIS). The method includes building a data index table according to word noun information of a power grid device and facility selected from the power grid GIS, extracting semantic key words from the data index table, building a reverse index table composed of the semantic key words, matching received key words in a retrieval input item and the key words in the reverse index table to obtain a retrieval result, and outputting the retrieval result. By means of the method, retrieval efficiency can be improved, and intelligent searching of power grid resources is further achieved.

Description

technical field [0001] The present invention relates to the field of grid geographic information systems, and more particularly to a method and device for providing information on grid equipment and facilities. Background technique [0002] With the in-depth application of GIS (Geographic Information System, geographic information system) technology in the production and operation of the power grid, the spatial information data of the power grid has also begun to show an explosive growth trend. In the existing power grid GIS technology, the main applications are "graphic display" and "map attribute mutual query", which realizes the corresponding correlation query between graphics and attributes, but in terms of intelligent information retrieval and display for power grid facilities / equipment It is still relatively weak. How to improve the information mining ability of power grid GIS technology has become an urgent problem to be solved. [0003] In the existing power grid G...
