Abstract

The embodiment of the invention provides a railway accident fault correlation and accident fault reason analysis method and system. The method comprises the steps of constructing a railway accident fault knowledge graph; based on the railway accident fault knowledge graph, performing name normalization on all accident fault names and all accident fault reasons, and then performing unified coding to obtain an accident fault and reason number table; inputting the accident fault and reason number table into a collaborative filtering analysis model to generate a reason similarity matrix; based onthe reason similarity matrix, obtaining the most possible accident fault reason recommendation corresponding to each accident fault name; inputting the accident fault and reason number table into a collaborative filtering analysis model to generate an accident fault similarity matrix; and based on the accident fault similarity matrix, obtaining an accident fault set caused by each accident fault reason. According to the embodiment of the invention, by fusing the knowledge graph and the recommendation algorithm, the accuracy of accident fault association and reason analysis is improved, and theguarantee of railway safety operation is enhanced.

Description

technical field [0001] The invention relates to the technical field of railway safety, in particular to a method and system for railway accident fault correlation and accident fault cause analysis. Background technique [0002] Railway transportation safety is a complex safety system engineering, and there are correlations and coupling relationships between accidents and failures. [0003] But on the one hand, due to the lack of various fault descriptions and lack of standard terms in the fault data of railway accidents. For example, regarding the "turnout no indication" fault in the failure of electrical signal equipment, there are "no indication of turnout positioning", "no indication of turnout reverse position", "out of turnout positioning", "out of turnout indication", "out of turnout indication" and "out of turnout indication". Inverse position loss expression" and other expressions make it easy to analyze the same accident fault as multiple accident faults during dat...
