Applications of Digital Twin Technology in AUV

Digital twin is driven by multi-dimensional virtual model and fused data, through virtual and real closed loop interaction, to achieve monitoring, simulation, prediction, optimization and other practical functional services and application requirements. At present, there are three problems in digital twin, and the concept of digital twin is controversial. Digital twin lacks a practical model-device data communication method. There are few applications of digital twin, especially in the field of AUV. Based on the above three problems, this paper first summarizes the concept and applications of digital twin. Then, an center server data transfer framework is proposed for model to device data communication. Finally, the application method of digital twin in AUV is discussed.
