Offshore material supply method

Abstract

The invention provides an offshore material supply method. The offshore material supply method is suitable for offshore supply of a multi-rotor unmanned aerial vehicle. Alternating current output by aship-borne power supply is converted into low-voltage direct current to be supplied to the unmanned aerial vehicle for use, so that the problems of limited onboard battery capacity, insufficient power, small carrying capacity, short endurance, poor wind resistance and the like of an existing multi-rotor unmanned aerial vehicle in the offshore supply process are overcome, and the transportation capacity and the wind resistance of the multi-rotor unmanned aerial vehicle during offshore ship material supply are improved.

Description

technical field [0001] The invention belongs to the field of vertical supply at sea, and in particular relates to a method for supplying materials at sea based on a multi-rotor unmanned aerial vehicle. Background technique [0002] The use of drones to transport materials between ships at sea has many advantages such as fast maneuverability, simple supply equipment, less manpower consumption, flexible operation, and little influence by sea conditions. At the same time, it can also realize the simultaneous supply of required materials by multiple ships. , especially medicines, blood plasma and other urgently needed supplies and medical supplies. In comparison, fixed-wing UAVs with longer wingspans are not suitable for transporting materials on ship decks with limited space. Multi-rotor UAVs are light in body and flexible in operation, and are suitable for transporting materials between ships. However, existing multi-rotor UAVs generally have problems such as limited onboard ...

AI Technical Summary

Problems solved by technology

In comparison, fixed-wing UAVs with longer wingspans are not suitable for transporting materials on ship decks with limited space. Multi-rotor UAVs are light in body and flexible in operation, and are suitable for transporting materials between ships. However, existing multi-rotor UAVs generally have problems such as limited on-board battery power, insufficient power, small carrying capacity, short battery life, and weak wind resistance.

[0003] In the prior art, "A UAV Replenishment Device Based on Hydropower" (CN201510629950.5) is aimed at the power source of the UAV during sea replenishment, and fails to effectively solve the problem of long-term battery life of the UAV; " A Ship Replenishment Method Based on Beidou Relative Positioning and UAV Control Technology" (201910177063.7) uses the position information provided by the Beidou positioning system to control the UAV to replenish ship materials, but ordinary UAVs with batteries are heavy The bearing capacity is greatly reduced, and the wind resistance is low due to insufficient energy, so the patented method has certain application limitations
