The invention provides a steel hot rolling management and
control system and method based on digital twinning. The
system comprises a sensing module used for sensing the environment of a physical factory, the equipment operation condition and the quality attribute of a
hot rolled slab; the data module is used for carrying out
data acquisition, data storage, data fusion,
data transmission and
data analysis on the sensed environment, equipment and the
hot rolled plate; the presentation module is used for representing the production condition of a real physical factory by adopting virtual twin images through three-dimensional graphic rendering and
augmented reality technologies on the basis of the analyzed data; and the control module is used for forming
decision control suggestions based on the fault
knowledge base according to the control target and the corresponding control rule, and sending out a control instruction. According to the fault diagnosis method based on the multi-scale
convolutional neural network, the operation state of the equipment is monitored, the abnormal condition of the equipment can be effectively judged, and a corresponding fault
knowledge base is matched to give a repair suggestion.
