Abstract

The invention discloses a knowledge graph construction method based on a fault mode and influence analysis information. The method comprises the following steps: constructing an equipment structure agreed level function block diagram and an FMEA table under each agreed level; according to an equipment structure agreed hierarchical function block diagram, node type labels are determined hierarchically, node attributes are supplemented, and component nodes are imported into a knowledge graph; according to the node type labels, hierarchically connecting the component nodes in the knowledge graph, and determining a trunk structure of the knowledge graph according to the subordination relationship among the component nodes; taking each kind of related fault information of the equipment as a fault information node, and importing the fault information node into the knowledge graph; establishing a relationship between each component node and a fault information node according to related fault information of each component under each agreed level in the FMEA table; and deleting redundant nodes and relationships to obtain a final knowledge graph. According to the invention, the fault association among the components in the equipment can be visually displayed, and the FMEA information can be quickly and effectively searched.

Description

technical field [0001] The present invention relates to the technical field of information visualization, and more specifically relates to a knowledge map construction method based on failure mode and impact analysis information. Background technique [0002] In the development stage of equipment, reliability, maintainability and supportability are the three most basic quality characteristics of equipment, which require key design and analysis to ensure that the equipment maintains good performance in the process of subsequent use. Among them, supportability analysis and design determine whether the design characteristics of equipment and planned support resources can meet the requirements of peacetime combat readiness and wartime use, affect the completeness of combat readiness and mission continuity of equipment, and restrict the combat effectiveness of equipment. [0003] Failure mode and effects analysis (FMEA), as a commonly used support analysis technique, needs to ana...
