Nuclear power equipment quality tracing method and system, computer equipment and medium

Abstract

The invention relates to a nuclear power equipment quality tracing method and system, computer equipment and a medium. The method comprises the following steps: S1, obtaining related data for quality tracing; S2, constructing a knowledge graph for quality tracing; and S3, performing quality event tracing query by using the knowledge graph for quality tracing. According to the nuclear power equipment quality tracing method provided by the invention, knowledge can be automatically extracted from data resources related to nuclear power quality and fused and processed to form the knowledge graph which reveals the traceable incidence relation of quality characteristics, and the content of the knowledge graph is updated and expanded through the knowledge. According to an input quality event, driving automatic traceability of a quality problem occurrence position along a quality forming path and correlation analysis of a quality problem generation reason by utilizing related knowledge required by quality traceability and stored in the knowledge graph, and realizing traceability of the whole life cycle quality event of the nuclear power equipment.

Description

technical field [0001] The invention relates to the field of nuclear engineering, and more specifically relates to a method, system, computer equipment and media for quality traceability of nuclear power equipment based on knowledge graphs. Background technique [0002] Nuclear power has the most stringent requirements on quality and safety, and there is a strictly formulated quality assurance and monitoring system to ensure the safety of nuclear projects. In the process of design, production, manufacture, installation, commissioning and trial operation of nuclear power equipment, if a quality event occurs, quality traceability with the quality event as the origin is a necessary link to ensure the quality and safety of nuclear power. [0003] In the existing technology, the quality traceability method of nuclear power equipment is generally to set up an expert group to conduct step-by-step investigations according to the established quality traceability process of the enterp...

Problems solved by technology

[0005] However, due to the poor versatility of knowledge graph technology in different fields, in the process of applying it from general fields to vertical fields, it is necessary to redesign the data source, knowledge extraction target, knowledge extraction method, and knowledge content structure of knowledge graphs. The implementation of this process requires a professional background in the vertical field, expertise in knowledge graph technology, and a deep understanding of the business

However, the technology of nuclear power equipment is complex and has strict safety requirements. How to select the data source for building the knowledge graph of nuclear power equipment quality traceability, how to design the content structure for the knowledge graph of nuclear power equipment quality traceability, and how to design the quality of nuclear power equipment based on the knowledge graph The traceability method has become a difficulty that hinders the application of knowledge graphs in the quality traceability of nuclear power equipment

Therefore, in the prior art, there is no precedent for using knowledge graphs for nuclear power equipment quality traceability, and there is no intelligent quality traceability method for nuclear power equipment based on knowledge graphs
