Problems solved by technology

Among them, unmanned ships have outstanding advantages such as strong maneuverability, high safety, and good concealment. Unmanned surveillance vessel supported by mother ship

[0003] There are two main problems facing the autonomous operation of unmanned ships in the open sea. One is the lack of energy supply for long-distance operations. At this stage, most unmanned ships use fuel or batteries as energy sources. Marine Exploration Requirements

The second problem is that the ability to sense the water surface in the ocean environment is limited. The sensing sensors carried on the unmanned ship are at a low height from the water surface, which is easily affected by waves and has a limited field of vision.

The shortcomings of the existing technology: the use of vertical axis wind turbines to generate electricity from wind energy, the power generation efficiency is low, it is difficult to meet the power demand of various equipment of unmanned ships, and it is impossible to coordinate the balance between power generation and the rapidity of ship navigation; A trumpet-shaped hole is opened in the center of the hull to place the solar panel. The solar panel layout area is small and the power generation is small, which makes it difficult to meet the equipment power demand of unmanned ships; Poor capability; unmanned ships lack the three-dimensional perception ability of surrounding environment information, and are prone to limited perception caused by sensor failure in complex ocean environments

The shortcomings of the existing technology: using sail as the main propulsion device, electric propulsion as the secondary propulsion device, due to the particularity of sail propulsion, it is difficult to maintain the course stability of the unmanned ship, so this unmanned ship cannot perform Marine monitoring tasks that require high navigational trajectory maintenance capabilities, such as submarine topography and landform mapping tasks that require unmanned ships to carry multi-beam bathymetry imagers; wing sails will form shadows on the hull, reducing the power generation of solar panels, and it is difficult to meet the requirements of unmanned ships. Power requirements for manned ships; unmanned ships lack adaptive stability adjustment capabilities under harsh sea conditions, and the wind tilting moment caused by sails is greater, resulting in poor survivability of unmanned ships; The three-dimensional perception capability of environmental information is prone to limited perception caused by sensor failure in complex marine environments

However, the above-mentioned technical solution has the following technical problems: the unmanned ship has the problem of poor endurance, and the search and rescue range is small; the UAV cannot carry out a single long-term work. At present, the endurance time of ordinary multi-rotor UAVs is generally less than 0.5h , if the device is equipped with other functions, the time will be shortened, which leads to a certain limitation in the search and rescue range of the invention, and it is impossible to realize long-distance and large-scale operations

However, this technical solution has the following defects: the application scenario of search and rescue ships is often the golden rescue time after water safety accidents, and the speed and efficiency of search and rescue should be the highest priority of the technical solution. The three-dimensional perception capability of the UAV, the automatic battery replacement and charging system on the unmanned ship realizes landing charging and improves battery life. It is difficult to control the battery, charging and take-off and landing
