Problems solved by technology
In the prior art, navigation mainly relies on acoustic systems, such as sonar, USBL (ultra-short baseline), SBL (short baseline), LBL (long baseline), etc., but the accuracy of sonar navigation is low and precise docking cannot be achieved. It is difficult to lay the baseline, and the baseline positioning system is expensive and costly

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] Non-contact charging through the electromagnetic coupler is through the transmission of power between the primary coil and the secondary coil. When an alternating current passes through the power transmission coil, alternating magnetic fluxes are generated between the primary coil and the secondary coil. As a result, an induced electromotive force that changes with the magnetic flux is generated in the secondary coil, and the terminal of the secondary coil outputs an alternating current to the outside.
[0027] To realize underwater non-contact charging, the AUV equipped with the energy compensation unit and the primary coil of the electromagnetic coupler needs to be docked with the secondary coil of the underwater operation unit to realize electromagnetic coupling. In the solution described in the present invention, The AUV is equipped with an energy compensati...

The invention provides a method for conducting noncontact charging on an underwater operation unit through an AUV. According to the method, an electromagnetic coupler primary side coil is loaded through the AUV, the AUV operates to the position of the underwater operation unit, the attitude is adjusted, the electromagnetic coupler primary side coil is coupled with a secondary side coil of the sideof the underwater operation unit, and noncontact charging is achieved. In the process that the AUV operates to the underwater operation unit, an artificial signal beacon is arranged on the sea surface, a three-dimensional coordinate system with the artificial signal beacon as an original point is established, the coordinates of a hovering point are calibrated through the three-dimensional coordinate system, relative navigation is achieved, AUV accurate navigation and hovering are achieved, and the underwater navigation difficulty is reduced.
Description
technical field [0001] The invention relates to the technical field of underwater robots, in particular to a method for non-contact charging of an underwater operation unit by using an AUV. Background technique [0002] At present, the underwater operation units (such as underwater sensors, etc.) on the market are all automatically scrapped by consumption or charged by frogman or replaced by power supply to maintain the energy of the underwater operation unit. [0003] The use of consumable and automatically scrapped underwater units will result in waste of resources and pollution of the underwater environment; while replacing or charging the power supply through manual work is highly dangerous and requires high personnel skills, and manual work in the water Lower work efficiency. [0004] The untethered underwater robot is also called an autonomous underwater vehicle (Autonomous Underwater Vehicle, AUV for short). Autonomous underwater robot is a new generation of underwa...
