Steel hot rolling management and control system and method based on digital twinning

Abstract

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.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a digital twin-based management and control system and method for steel hot rolling. Background technique [0002] The concept of digital twins was first proposed by the Apollo project in the United States to monitor the status of various indicators of the space shuttle through virtual twins. Digital twin technology refers to twinning the real physical world into a nearly identical virtual simulation world through digital means, through the integration and information interaction of different control layers at the production level, and the comprehensive application of artificial intelligence, edge computing, and data mining technologies to realize the transformation from the physical world to the virtual world The all-round synchronous mapping simulation process is mainly used in product design, research and development, manufacturing, service and operation and maintenance.

Problems solved by technology

[0005] However, the current digital twin technology is not mature. Most of the current research is only on process modeling, data fusion and interactive collaboration, and there is basically no investment in service-oriented and production applications. In particular, most research is only invested in the product design stage. In the initial stage of product development, the investment in research and development in the actual manufacturing process and production control of the product is minimal

On the other hand, in the management and control of traditional production plants, although automation and informatization management have been basically realized, there is a lack of system simulation analysis and decision-making feedback mechanisms. There are still information barriers at different control levels, and it is impossible to realize the intercommunication of all information. In terms of performance, the degree of data visualization is not high, and it is impossible to show the whole production process with intuitive data charts or three-dimensional images, and there is also a lack of simulation analysis and decision-making models to support production
