The application discloses an industrial equipment maintenance method, and belongs to the technical field of equipment management. The method comprises the following steps: determining a multi-dimensional representation sub-model containing geometric, physical, data-driven and knowledge models based on obtained multi-source priori and monitoring data; generating a fusion sub-model and a reduced-order solving model by combining the sub-model based on a preset multi-model bidirectional closed-loop fusion mechanism and a multi-physics field collaborative solving and reduction strategy, wherein the fusion mechanism represents cross-domain interaction, mechanism constraint and parameter reverse correction among the sub-models, and the reduction strategy represents differential collaborative calculation and low-dimensional reduction mapping rules of different coupling strength physical fields; constructing a multi-scale equipment maintenance model based on the fusion sub-model and the reduced-order solving model; and inputting real-time monitoring data into the model to obtain a maintenance strategy containing fault root cause positioning and scheme optimization. The method realizes four-layer model deep fusion and efficient reduction simulation, solves the problems of model fragmentation and lack of mechanism constraint, and improves the whole life cycle management and control capability.
