A docking system and docking method for an unmanned ship and auv

Abstract

A docking system between an unmanned ship and an AUV, including an unmanned ship on the water surface, an underwater AUV, and an ultra-short baseline positioning system for positioning and initial docking between the unmanned ship and the AUV, for A wireless charging module that realizes non-contact charging between the unmanned ship and the AUV; the bottom of the unmanned ship is equipped with a multi-degree-of-freedom manipulator for clamping the AUV and fine-tuning the docking position. The invention realizes the docking between the unmanned ship and the AUV through the ultra-short baseline positioning system, machine vision and manipulator, improves the reliability and success rate of the docking, and performs charging and data transmission after the docking to improve the endurance of the AUV.

Description

technical field [0001] The invention belongs to the field of marine technology engineering, and relates to a docking system and a docking method for an unmanned ship and an AUV. Background technique [0002] There are two common types of unmanned underwater vehicles: Remotely Operated Vehicles (ROV) and Autonomous Underwater Vehicles (AUV). The ROV obtains energy through the umbilical cable connected to the water surface, with sufficient power, the working time is not limited by energy, and the working efficiency is high. AUV relies on its own autonomous ability to manage and control itself to complete the assigned mission. It has a large range of activities, good mobility, high degree of intelligence, and strong autonomy. Both of the above-mentioned underwater robots have disadvantages: among them, ROV usually needs to be equipped with a mother ship, the mother ship and a series of staff have huge expenses, and the range of activities is limited; AUV is limited by its own ...

AI Technical Summary

Problems solved by technology

Both of the above-mentioned underwater robots have disadvantages: among them, ROV usually needs to be equipped with a mother ship, the mother ship and a series of staff have huge expenses, and the range of activities is limited; AUV is limited by its own energy, and its endurance is limited; and due to underwater Long-distance wireless communication cannot be carried out, and the data obtained by AUV's underwater detection is difficult to transmit back in real time

This docking method of fixed-point clamping can be successful under ideal conditions without interference, but the actual situation is that the connecting umbilical can only limit one degree of freedom in the height direction of the submersible, and cannot limit other degrees of freedom, such as the rotation of the submersible , pitching, etc. We all know that the sea conditions are very complicated, and the unmanned submersible will inevitably be disturbed and shaken when it is pulled to the water surface for docking. In addition, the docking is carried out on the water surface when it is pulled out, and the submersible cannot actively adjust it. The success rate to the target point will be very low
