Description

technical field [0001] The invention belongs to the technical field of underwater docking and charging for underwater robots, and in particular relates to a non-contact charging system for a submarine cable inspection AUV and a guiding and docking method thereof. Background technique [0002] Due to the capacity of the battery, the conventional submarine cable inspection AUV has limited battery life. After driving for a period of time, it needs to float up for charging before continuing to use. During the operation, it will affect the continuity of continuous submarine cable inspection. [0003] AUV will play an important role in ocean development, underwater environment exploration and future underwater warfare, and the most important thing is to solve the energy supply technology of AUV. AUVs have their own energy to navigate autonomously and can perform large-scale detection tasks, but their endurance is limited, which makes the operation efficiency not high. If they use...
