Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of lack of adaptability and flexibility in dealing with information-oriented problems due to the neglect of the action form of the data flow in the prior art, which makes it difficult to form a closed-loop feedback from information to the physical domain. On the other hand, the information domain is ignored When dealing with physical information systems, there is a deviation between the problem analysis and the actual situation, which is not conducive to problem solving. This makes it difficult for the existing functional model theory to fully reflect the composition of production line components and the interaction between components. The proposed A testable digital twin modeling method for intelligent production lines

Abstract

The invention discloses a testable digital twinning body modeling method for an intelligent production line. The method comprises the following steps: A, constructing a physical entity module function model by utilizing a physical entity module; B, constructing a virtual entity function model by utilizing the virtual entity module; C, constructing an interaction channel function model by utilizing an interaction channel module; D, performing linkage combination of the function models. The invention has the beneficial effects that closed-loop feedback from the production line physics to the information domain is formed through model linkage, the information domain characteristics of the production line including the data flow effect and the element virtual effect are comprehensively displayed, the defect that an existing functional model is insufficient in adaptability to the production line is overcome; meanwhile, by means of the functional model, designers can perform comparative analysis on different element combinations to discover potential functions, so innovative design of a production line is realized.

Description

technical field [0001] The invention relates to the technical fields of production line digitalization and intelligent manufacturing, and in particular to a method for modeling a testable digital twin of an intelligent production line. Background technique [0002] Digital twin is a simulation process that makes full use of physical models, sensor updates, operation history, etc., integrates multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and completes the mapping in the virtual space to reflect the entire life cycle of the corresponding physical equipment. process, digital twin is a concept that transcends reality, and can be regarded as a digital mapping system of one or more important and interdependent equipment systems. Digital twin is a generally applicable theoretical and technical system that can be applied in many fields. It is widely used in production line design, production line manufacturing, medical analys...
