The invention discloses an
industrial software cloud base intelligent operation and maintenance and fault self-healing method based on digital twinning, and relates to the technical field of digital twinning. According to the method, the hierarchical digital twinborn model is constructed and dynamically updated, and the operation state of the
cloud base is accurately mapped and visually displayed in combination with independent visual modules of a
physical layer, a logic layer and an
application layer; the method comprises the following steps: calibrating a reference value in real time through a dynamic reference
library, quickly identifying abnormity of each layer, generating graded early warning, improving abnormity response timeliness, constructing a dynamically updated fault
knowledge graph based on historical fault data, integrating a multi-dimensional
correlation analysis and confidence coefficient
verification mechanism, positioning a unique fault reason, greatly shortening a fault diagnosis period, and improving fault diagnosis efficiency. And a strategy
library is constructed based on a fault
knowledge graph and historical self-healing cases,
simulation verification is carried out on candidate strategies through a digital twin model, the effectiveness of the self-healing strategies is ensured, and then the self-healing strategies are issued and executed, so that intelligent and automatic fault repair is realized, and stable operation of the
cloud base is ensured.
