DTMR: Industrial Digital Twin Architecture for New Production Line Design in Mixed Reality Environment

In recent years, the rapid development of digital twin technology has promoted the interaction and integration of digital twin technology in physical space and cyberspace thus becoming a research hotspot for application in various manufacturing services. In this paper, we propose DTMR, a technical architecture for joint new production line simulation design with digital twin real-time mapping in mixed reality environment. This real-time co-simulation ensures the realistic behavior of assets in physical space, thanks to the simulation of the digital twin technology and the 3D natural interaction interface provided by the mixed reality environment. The paper also experimentally validates the feasibility of the system architecture and evaluates the ergonomic characteristics of the operators based on the Posture Ergonomics Risk Assessment (PERA) methodology.
