Development of dynamic digital twin system for deep-sea mining

Abstract

Digital twins are a kind of digital industrial technologies developed in recent years. This paper introduces the construction process of dynamic digital twin system for deep-sea mining system. Deepsea mining system has a complex composition, complicated operation procedure, and extreme working environment. It is of great significance to establishing dynamic digital twin system for deep-sea mining system to carry out visual monitoring and data management for the whole life cycle of mining process, and realize interactive control in the deep-sea mining operation. In this paper we establish a high-precision and multi-scale digital model for the physical entities of deep-sea mining system, which maps the mining system from physical object to digital space to drive the digital model with updated status collected from physical space. The application framework, key technologies, development process and operation process of the system are explained, and the development process of dynamic digital twin system for deep-sea mining based on state diagnosis is expounded, which is of great significance in deep-sea mining.
