Problems solved by technology

According to the traditional search method of keywords, it is difficult to find or find all maintenance records with the same or similar semantics to assist maintenance. The rich maintenance knowledge accumulated in the past can only be sealed in historical maintenance records, and its due value cannot be fully utilized.

Abstract

The invention provides a method for semantically searching equipment maintenance records based on map matching. The method comprises the following steps: (1), constructing an industrial equipment classification system and a dictionary, and entering them into a database for storage; (2), preprocessing fault maintenance records; (3), obtaining a map segment of fault description; (4), obtaining The extended map fragment of the fault description; (5) Obtaining the template information of the fault description; (6) Combination search strategy, including at least precise search, semantic accommodation search, device combination search, device down search, fault down search, device Search up, fault search up. Based on graphing fault phenomena described in natural language, this method provides a basic method of graph matching search for different application scenarios, which can realize accurate understanding of user intentions and rapid semantic search of equipment maintenance records.

Description

technical field [0001] The present invention relates to information utilization technology, and specifically relates to a basic method of map matching search for different application scenarios on the basis of graphing fault phenomena described in natural language, which can realize accurate understanding of user intentions and fast equipment Semantic Search for Maintenance Records. Background technique [0002] Intelligent operation and maintenance is an important link in intelligent manufacturing and an important aspect of industrial transformation and upgrading of enterprises. In the long-term production and operation, enterprises have accumulated a large amount of equipment maintenance historical data, including equipment failure phenomena, failure causes and maintenance plans and other information. How to maximize the use of these large amounts of historical equipment maintenance data is of great significance for enterprises to quickly and accurately discover the cause...
