The invention relates to a digital twinning-based multi-device dynamic cooperative control method for a
cut tobacco
production line, and the method comprises the steps: 1-5, constructing a digital twinning body of the
cut tobacco
production line through employing a three-dimensional unified modeling frame of a geometric model, a
physical model and a behavior model, constructing a distributed cooperative
control network architecture based on edge calculation, and constructing a multi-device dynamic cooperative
control system of the
cut tobacco
production line; data interaction is realized among all
layers by defining an interface function, modeling is performed on interaction among devices by adopting a GNN neural network, a global
coupling relation
quantitative model of a device cluster is established,
time sequence alignment is performed on multi-sampling
frequency data by adopting a
time distortion function, abnormal data is detected and eliminated by adopting an
anomaly detection method based on a
mahalanobis distance, and the device cluster is obtained. A three-dimensional
evaluation system of key indexes is constructed, a comprehensive
evaluation function is calculated, a two-stage architecture of a steady-state optimization layer and a dynamic adjustment layer is adopted, and global collaborative optimization of the cut tobacco production line under a dynamic working condition is realized by combining digital twinning rehearsal
verification, virtual and real
millisecond-stage synchronization, three-stage early warning and fault collaborative self-healing.
