doi:10.16182/j.issn1004731x.joss.23-1175

Abstract

Abstract:

In order to address issues of opacity in production information and difficulties in collecting equipment data in shipbuilding workshops, a digital twin ship manufacturing workshop monitoring system is designed based on the Unity physics platform. The essential steps in building a virtual reality platform are outlined, encompassing the creation of a virtual ship workshop, the development of data transmission methods for multi-source heterogeneous data acquisition, implementation of data-driven methods for achieving virtual-real synchronization, and enhancement of data visualization capabilities. By practically designing a real-time monitoring system for the welding assembly line production process in shipbuilding, the 3D scene reproduction of the welding assembly line and production monitoring of the digital twin workshop in the virtual scene are achieved. The feasibility of constructing this system is validated through the consistency verification between the virtual and physical workshops.

Key words: multi-source heterogeneous data collection, virtual-real synchronization, data visualization, digital twin workshop, production monitoring, consistency verification
