Industrial equipment digital twinning construction maintenance method and system based on data driving

Abstract

The invention belongs to the field of industrial equipment digital twinning, particularly relates to an industrial equipment digital twinning construction and maintenance method and system based on data driving, and aims to solve the problem that the application range and efficiency cannot be both considered in the construction and maintenance process of a digital twinning body. The method comprises the following steps: learning industrial equipment labeling data through a data-driven deep learning network to construct a digital twinborn body, and carrying out multi-modal fusion; carrying out multi-modal fusion model training on data of different enterprises through federal learning; new sample space distribution is continuously learned through lifelong learning, and the multi-modal fusion model is updated online; and carrying out industrial equipment health management through the model. According to the method, a complex equipment health management scene in which mechanism modeling is difficult, data sharing is difficult and new fault types continuously occur in a long-term operation and maintenance process in a real industrial scene can be overcome, and the digital twinborn body is vivid, robust, robust and credible.

Description

technical field [0001] The invention belongs to the field of digital twins of industrial equipment, and in particular relates to a data-driven digital twin construction and maintenance method, system and equipment for industrial equipment.
