Embodiment Construction
[0040] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0041] The present invention takes the fault diagnosis of industrial machinery and equipment as the carrier, takes the knowledge map and the LSTM algorithm as the main algorithm framework, and the method flow is as follows: figure 1 shown, including the following steps:
[0042] S1: Collect text information and time series sample data about the diagnostic target device, where text information is used as device mechanism knowledge, and time series sample data is used as device operation data;
[0043] S2: Extract rules for equipment mechanism knowledge, and symbolize the rules to extract indicators that can be used as classification basis 1 (f 1 ), index 2 (f 2 ) until the index n(f n );
[0044] S3: Combine and classify the extracted indicators to obtain different levels and types of rule nodes of the knowledge graph, including firs...
