The invention relates to the technical field of fault diagnosis, and provides an equipment fault diagnosis method and device. The method comprises the following steps: acquiring equipment fault record data, equipment fault diagnosis data and an expert diagnosis knowledge base; processing the equipment fault record data by using the equipment mechanism diagnosis model to obtain first diagnosis data; processing the equipment fault record data by using the knowledge graph diagnosis model to obtain second diagnosis data; processing the equipment fault record data through the first neural network model to obtain third diagnosis data; marking the first diagnosis data, the second diagnosis data and the third diagnosis data to obtain a marking result, and training a second neural network model by using the marking result; constructing a diagnosis model by using the second neural network model, the equipment mechanism diagnosis model, the knowledge graph diagnosis model and the first neural network model; and using the diagnosis model to diagnose the fault equipment.
Description
technical field [0001] The present disclosure relates to the technical field of fault diagnosis, and in particular, to a method and device for fault diagnosis of equipment. Background technique [0002] At present, the common method for diagnosing equipment faults is to use the expert knowledge in the field of equipment faults to judge the fault cause of the faulty equipment, such as a fault tree, or to use the knowledge graph to diagnose the fault cause of the faulty equipment. However, whether it is to use the expert knowledge in the field of equipment faults or the knowledge graph to diagnose the fault causes of the faulty equipment, there are problems of low efficiency and low accuracy. [0003] During the process of realizing the concept of the present disclosure, the inventor found that the related art has at least the following technical problems: the diagnosis of equipment failure has the problems of low efficiency and low accuracy. SUMMARY OF THE INVENTION [000...
