Digital twinning body for production line and construction method and application thereof

Abstract

The invention discloses a digital twinning body for a production line and a construction method and application thereof, and the digital twinning body comprises: a unit domain which comprises a staticmodel and a dynamic model of physical equipment, provides a data carrier for a data domain, and provides a model basis for the implementation of a behavior domain; the data domain which is used for acquiring operation data of physical equipment and products and instruction data of the digital management system, performing format conversion and storage on the acquired data according to a unified data structure, and supporting a behavior domain to access the data; and the behavior domain which is used for defining semantic description of each behavior in the operation process of the productionline, and driving a model of the unit domain to operate synchronously with the physical world according to the data acquired by the data domain. The digital twinning body can be quickly deployed in areal production environment, and operations such as monitoring, simulation and prediction are carried out on production from different dimensions.

Description

technical field [0001] The invention relates to the technical field of digital intelligent manufacturing, in particular to a digital twin for a production line and its construction method and application. Background technique [0002] Digital manufacturing is the development direction of the industrial manufacturing field. Since the 1950s, digital manufacturing has mainly gone through the stages of computer-aided design, integrated manufacturing, networked manufacturing, and the current stage of intelligent manufacturing. [0003] Digital Twin (Digital Twin) is a concept beyond reality, which can be regarded as a digital mapping system of one or more important and interdependent equipment systems. The simulation process of multi-discipline, multi-physical quantity, multi-scale and multi-probability is mapped in the virtual space to reflect the whole life cycle process of the corresponding physical equipment. [0004] In the stage of intelligent manufacturing, digital twin t...
