Problems solved by technology

[0005] The goal of digital twin technology is to create a more realistic virtual model of manufactured products to bridge the gap between design and manufacturing and to reflect the real and virtual worlds. At this stage, there is still no one-to-one correspondence between the digital world and the physical world. map
[0006] The current digital twin system generally uses the computer 3D model built in advance as the digital entity in the digital twin system, and there is a lack of combined use cases of the digital twin system and virtual imaging technology, and the application of virtual imaging technology will directly improve the digital twin The user perception and immersion of the system, and for large-scale digital twin systems, such as space exploration, digital factories, virtual cities, etc., traditional computer 3D models cannot provide more detailed descriptions at the same time due to the single user perspective
[0007] At present, strong information mapping between digital entities and physical entities cannot be achieved, that is, digital entities lose a lot of valuable information in the process of tracking physical entity information
On the one hand, due to the bandwidth limitation of the sensor acquisition equipment, the scope of the collected information is limited; on the other hand, due to the limited computing power of the terminal processor, it cannot carry the analysis and processing of massive data
[0008] The current information transmission method for the digital twin system is no longer applicable to the virtual imaging technology that requires a large amount of data stream support, especially when long-distance information transmission is required between the digital twins. It is generally incompetent for digital twin systems, and it is difficult for the system to balance real-time and information integrity

Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] The digital twin system is one of the core technologies of the CPS system. For the digital twin system, its terminal display requires massive data support, but limited by the information transmission bandwidth, it is necessary to extract and filter value information before information transmission. The digital twin system will generate a la...

Abstract

The invention relates to a strong mapping digital twin system based on a virtual imaging technology. According to the system, a multi-information cooperative communication mechanism is established between digital twin bodies, morphological information, state information and behavior information of a physical entity system are collected through multiple sensors and sent to an edge computing node, and the edge computing node is responsible for receiving sensor information and carrying out edge computing processing on the received information; A virtual imaging technology is applied to project digital entities of the digital twin system into a real space in a three-dimensional visualization mode, meanwhile, state information of the physical entities is displayed in a virtual reality mode, thedetail display effect of the digital twin system is enhanced, and the requirements for multi-view observation and immersion experience are met; According to the system, strong information mapping isestablished between a physical entity and a digital entity through the process, and it is guaranteed that information is transmitted between twin bodies in real time at a high speed in an undistortedmode.

Description

【Technical field】 [0001] The invention belongs to the field of simulation technology, and specifically relates to a strong mapping digital twin system based on virtual imaging technology, which aims to support the implementation of digital twin technology in the 5G era and promote the evolution of digital twin technology from computer software simulation to real three-dimensional space. 【Background technique】 [0002] In intelligent manufacturing, the manufacturing-oriented CPS cyber-physical system is regarded as the core technology of Industry 4.0. By constructing a closed-loop channel for data interaction between information space and physical space, CPS can realize the interactive linkage between information virtual body and physical entity. With the development of IoT technology, the integration of multi-science, multi-physical quantities, and multi-scale simulation processes is becoming more and more accurate by using data such as physical models, sensor updates, and o...
