Research on Data Transfer Scheme of Virtual-Real Interactive in Five - Dimensional Digital Twin System

Abstract

Digital twin is an advanced enabling technology that implements the fifth industrial revolution such as China's Intelligent Manufacturing 2025 and Industry 4.0. In the process of digital twin landing application, a five-dimensional model of digital twin is gradually evolved. There is no unified technical platform to realize cross-protocol and cross-platform data interaction between physical entity, virtual entity, twin data and service, which hinders the rapid landing of digital twin in the industry. In this paper, the technology of virtual-real data transfer-of industrial equipment is studied, and the data transfer scheme of virtual-real interactive is proposed. Under the experimental environment, the cross-platform and cross-protocol data transfer between physical machine tool entity, unity virtual machine tool entity, Adams virtual machine tool entity, system flow engine and twin database is realized. It lays a foundation for further research on the digital twin data transfer platform with unified interface, and expects to provide reference for peers in related fields.
