Embodiment Construction

[0066] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0067] Such as figure 1 As shown, the digital twin for the production line of the present invention includes three dimensions of unit domain, data domain and behavior domain, and the present invention constructs the digital twin from the above three dimensions.

[0068] The unit domain is the underlying implementation basis of the behavior domain. In this embodiment, the unit domain models the static and dynamic features of the equipment on the production line, providing a model basis for the realization of the behavior domain; the unit domain is the data carrier of the data domain. In this embodiment, the generation and existence of data depends on the model in the unit domain; the data domain ...

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...
