Abstract

The invention relates to an underwater glider fault real-time diagnosis method based on digital twinning, and belongs to the field of underwater vehicles. The method aims at solving the problem that an existing underwater vehicle fault diagnosis method is insufficient, and reference is provided for health management of the underwater vehicle. An underwater glider health management development platform based on digital twinning is constructed, the underwater glider health management development platform comprises an overwater health management system and an underwater health management system, and the overwater health management system comprises digital twinning model construction, system key component data interaction and updating model establishment and system fault recognition and risk assessment model establishment. The underwater health management system comprises key component data acquisition, digital twinborn model matching and updating, fault diagnosis and risk grading, state monitoring and feedback, and feedback of a test result to the digital twinborn model for updating and correction. According to the method, the accuracy of fault diagnosis during the underwater experiment period is effectively improved.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to a real-time fault diagnosis method for underwater gliders based on digital twins. Background technique [0002] As an underwater autonomous vehicle that obtains propulsion by adjusting its own net buoyancy and attitude angle, underwater glider has the characteristics of low energy consumption and strong endurance. Scope of ocean exploration needs. [0003] Because underwater gliders can only interact with each other after exiting the water during long-duration underwater navigation to realize data recovery and command update, obtain information such as attitude and energy consumption status, and predict, diagnose and tolerate potential faults. At present, a lot of research has been done at home and abroad. However, the underwater glider system is located in the deep sea when it actually works. The fault diagnosis needs to be carried out after a gliding cycle when the data is ...
