Digitization system based on digital twinning technology and construction method thereof

Abstract

The invention provides a digitization system based on a digital twinning technology and a construction method thereof. The digitization system comprises a data space subsystem and a data portal modulewhich are mutually communicated. The data space subsystem and the data portal module are taken as an integral body and form the digitization system based on the digital twinning technology corresponding to a target physical entity. The data space subsystem and the target physical entity form a mapping relation. The data space subsystem is used to store the description information of the target physical entity, a knowledge set, and the data of all categories in a whole life cycle process. The data portal module is used to provide a communication interface for information interaction between the data space subsystem and an external system. The external system comprises the target physical entity and other digitization systems and / or information systems. In the invention, the mapping relation with the physical entity can be accurately expressed, each component of the system and the specific content definition of each component can be clarified, and the application standard of the digitaltwinning technology is provided.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a digital system based on digital twin technology and a construction method thereof. Background technique [0002] The prototype of the concept of digital twin was first proposed by Professor Grieves of the University of Michigan in 2003, and gradually developed and improved. Its conceptual model was proposed in 2011, including physical products in physical space, virtual products in virtual space and the relationship between Data and information interaction interface. The definition of digital twin is to make full use of data such as physical models, sensor updates, and operation history, integrate multi-disciplinary, multi-physical quantities, multi-scale, and multi-probability simulation processes, and complete the mapping in the virtual space, reflecting the full range of corresponding physical equipment. life cycle process. The digital twin is to digitally create a...

[0004] However, the existing "three-dimensional structural model" and "five-dimensional structural model" are both in the conceptual model stage. There is no standard for the content of the modules, and the description of the interconnection relationship between the modules is not specific. How to establish digital expression There is no clear implementation method for the mapping of physical entities in digital space
