Crane monitoring method based on digital twinning, computer equipment and storage medium

The invention discloses a crane monitoring method based on digital twinning, computer equipment and a storage medium, and relates to the technical field of cranes, the method comprises the following steps: constructing a crane arm grid model; inputting the real-time dynamic data into a pre-trained RBF proxy model to output real-time coarse grid deformation data and real-time coarse grid stress data of the coarse grid nodes; coloring the crane arm grid model according to the real-time coarse grid deformation data or the real-time coarse grid stress data so as to generate a crane arm model with a cloud picture effect; processing a pre-constructed equal-proportion three-dimensional model of the crane arm according to the real-time component relationship so as to generate a prototype model without a cloud picture effect; and constructing a stress-strain digital twinborn model of the crane arm according to the crane arm model and the prototype model. By adopting the method, the geometric morphology and the stress-
