Digital system and its construction method based on digital twin technology

Abstract

The invention provides a digital system based on digital twin technology and its construction method. The digital system includes: a data space subsystem and a data portal module that communicate with each other. The data space subsystem and the data portal module are taken as a whole to form a target physical entity The corresponding digital system based on digital twin technology; there is a mapping relationship between the data space subsystem and the target physical entity, and the data space subsystem is used to store the description information, knowledge collection and all categories in the whole life cycle process of the target physical entity data; the data portal module is used to provide a communication interface for information interaction between the data space subsystem and external systems, and the external systems include target physical entities and other digital systems and / or information systems. The present invention can accurately express the mapping relationship with physical entities, and can clearly define each component of the system and the specific content of each part, thereby providing the application standard of the digital twin technology.

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
