Digital twin system of an intelligent production line

Abstract

The invention relates to a digital twin system of an intelligent production line, which comprises a physical space layer, an information layer and a virtual space layer. The physical space layer is composed of a physical production line, intelligent sensing devices and an industrial control network. The information layer includes a data conversion module, a data analysis module and a production line information database. The virtual space layer can adapt to a variety of platforms and environments including personal computers and handheld devices, is used for generating a virtual production line consistent with the physical production line by a 3D visual engine through online real-time and offline non-real-time rendering under the driving of the production line information database of the information layer, and has the functions of multi-angle of view visual display, natural interaction, state monitoring and so on. The real-time state information of the physical production line is collected by various intelligent sensing devices, and based on the information, a three-dimensional visual engine is driven to generate a virtual production line model consistent with the physical production line through rendering, thereby realizing the twin mirror image of the virtual production line and the physical production line.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to an intelligent production line digital twin system. Background technique [0002] Major countries in the world have proposed strategies to promote the development of their own manufacturing industries, such as the US Industrial Internet, German Industry 4.0, Made in China 2025, etc., which provide opportunities for promoting intelligent manufacturing. The purpose of these initiatives is to use information technology to realize the interconnection and intelligent operation of the physical world of manufacturing and the information world. 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 ...

AI Technical Summary

Problems solved by technology

However, after retrieving relevant patents and papers, it is found that the current implementation of digital twin systems still has shortcomings in real-time visualization, natural interaction, and multi-platform environment support. For example, some virtual 3D models are not consistent with physical models, and some virtual 3D models It is impossible to track and reflect the state of physical models in real time, and some cannot provide natural interaction methods, such as multi-view roaming, detailed zoom-in observation, etc., and some do not support platforms and environments such as remote and handheld devices
