Low-altitude positioning load air-drop method based on multi-rotor unmanned aerial vehicle

Abstract

The invention discloses a low-altitude positioning load air-drop method based on a multi-rotor unmanned aerial vehicle. The multi-rotor unmanned aerial vehicle comprises an aerial flight platform, onboard task equipment and a ground remote control device. The onboard task equipment is located below the aerial flight platform. The onboard task equipment comprises an air-drop engine, a positioning camera and a directional voice broadcast device. The method solves the problem that air-drop of badly-needed emergency supplies is difficult in emergency rescue. The multi-rotor unmanned aerial vehicle has the advantages of being low in cost, easy and convenient to operate and easy to maintain and facilitating transport; with the low-altitude hovering function of the multi-rotor unmanned aerial vehicle and the assistance of the onboard assistant task equipment such as the voice broadcast device and the positioning camera, material air-drop accuracy and utilization efficiency are improved. The method has outstanding application value for a small number of loads which is light and is badly needed by trapped persons, and has great popularization potential in the field of air-drop of emergency rescue supplies.

Description

technical field [0001] The invention relates to the technical field of low-altitude positioning and throwing of loads, in particular to a method for low-altitude positioning and throwing of loads based on a multi-rotor drone. Background technique [0002] In the emergency response to disasters, the transportation and delivery of relief materials is an important issue. In many cases, because the disaster occurred in an area with poor traffic or the disaster damaged roads and bridges, it was difficult for rescue forces to pass through on a large scale and go deep into the disaster site. At this time, there is a need for a measure that can carry a small amount of urgently needed materials, such as medicines, water, life buoys and masks, to break through the restrictions of unfavorable traffic conditions, and provide emergency assistance to the trapped people. On the one hand, it encourages the confidence of the trapped people and calms their emotions; on the other hand, it use...

AI Technical Summary

Problems solved by technology

[0004] For the trapped people who need load assistance, due to the limitations of transportation devices, on-site disaster environment, traffic conditions and disposal personnel, rescuers cannot be dispatched at the first time, and cannot achieve the fastest response

[0005] For disasters such as high-rise building fires, earthquakes, and rock landslides, the traffic conditions are inconvenient or severely damaged, and the ground is difficult to pass even on foot, hindering the transportation and delivery of relief materials

[0006] For the existing air delivery method of rescue supplies, on the one hand, it is inconvenient to dispatch the aircraft and consumes a lot of money. For throwing, it is difficult to accurately locate the throwing point, and there is a large waste of throwing materials, and the degree of utilization is low; and for helicopters to drop at low altitude, the operation is difficult and the risk is greater
