Satellite fault diagnosis method, device and equipment based on graph embedding and storage medium

The invention discloses a satellite fault diagnosis method, device and equipment based on graph embedding and a storage medium, and the method comprises the steps: obtaining a fault phenomenon query statement, carrying out the analysis of the fault phenomenon query statement, and determining a fault element; constructing a virtual sub-graph based on each fault element, determining a candidate sub-graph based on each fault element in combination with a pre-constructed satellite fault knowledge graph, determining a first target vector corresponding to the virtual sub-graph and a second target vector corresponding to each candidate sub-graph, and calculating the similarity between the first target vector and each second target vector, obtaining the similarity between each candidate sub-graph and the virtual sub-graph; and performing fault diagnosis based on the similarity corresponding to each candidate sub-graph in combination with the satellite fault knowledge graph to obtain a fault diagnosis result.
