Digital twin system and method applied to industrial production line

Abstract

The invention discloses a digital twin system and method applied to an industrial production line, wherein the system comprises a data collection device, a digital twin processing device, and a visualization device, and the data collection device is used for obtaining the state information data of a physical production line in real time through production equipment; then, an industrial control network transmits the data to the digital twin processing device and / or the visualization device; the digital twin processing device is used for processing and analyzing the information data acquired by the data collection device and transmitting the information data to the visualization device; the visualization device is used for analyzing the information data transmitted by the data collection device and / or the digital twin processing device through a three-dimensional visualization engine, generating a virtual production line model consistent with the physical production line and displaying the virtual production line model. According to the invention, twin mirroring of the virtual production line and the physical production line can be realized, and multi-view visual display, natural interaction and state monitoring can be carried out in an on-line real-time and off-line non-real-time manner.

Description

technical field [0001] The invention belongs to the technical field of intelligent production, and in particular relates to a digital twin system and method applied to industrial production lines. Background technique [0002] Intelligent factory is the only way to realize "intelligent manufacturing", and intelligent production line is the basis for realizing intelligent factory. However, at present, the physical space and information space of the production line are independent of each other, there is a lag in data transmission, the virtual and real spaces cannot interact and integrate in real time, and the level of intelligence is not high. In view of this situation, digital twin (DT) has attracted widespread attention as a technical means to realize the integration of cyber-physical system (CPS). [0003] Digital twin refers to copying a physical object in a virtual environment in a digital way, and synchronizes products, manufacturing processes and even the entire facto...

AI Technical Summary

Problems solved by technology

However, after retrieving relevant patents and papers, it is found that the current implementation of the digital twin system still has deficiencies in real-time visualization, natural interaction, and multi-platform environment support:

[0005] 1. Most of the digital twin scene construction cannot be separated from the technicians. Most of the construction work is compiled through code and does not have visual editing functions, such as the regular movement of the model, the creation of the client twin scene, and the reuse of the model. Support remote access, multi-platform deployment

Some cannot provide free interaction methods, such as roaming in twin scenes, detailed zoom-in observation, etc.

[0006] 2. Some 3D simulation models cannot track and reflect the state of the physical model in real time
