Unmanned aerial vehicle control method, plant protection operating method, unmanned aerial vehicle and earth station

Abstract

An embodiment of the invention provides an unmanned aerial vehicle control method, a plant protection operating method, an unmanned aerial vehicle and an earth station. The plant protection operating method comprises the following steps: operation flight path information sent by the earth station is obtained; the operation flight path information comprises operation object identities, an operation order, operation positions of operation objects, sprinkling duration of the operation objects and sprinkling radiuses of the operation objects; the operation positions, the sprinkling duration and the sprinkling radiuses of the operation objects correspond to the operation object identities; sprinkling operation is orderly performed on the operation objects in the operation flight path information according to the operation order; during the operation, when the unmanned aerial vehicle flies to an operation position corresponding to each operation object identity, the sprinkling operation is performed on a corresponding operation object according to a corresponding sprinkling radius and corresponding sprinkling duration. The unmanned aerial vehicle disclosed in the embodiment of the invention can be used for accurately sprinkling pesticide on fruit trees and crops, manpower cost can be lowered and sprinkling efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for plant protection operations, a method for controlling unmanned aerial vehicles to perform plant protection operations, an unmanned aerial vehicle and a ground station. Background technique [0002] Unmanned aerial vehicle (Unmanned Aerial Vehicle, UAV for short), is a kind of unmanned aircraft. UAVs are widely used and are often used in plant protection, urban management, geology, meteorology, electric power, emergency rescue and disaster relief, video shooting and other industries. [0003] With the development of UAV plant protection technology, UAV plant protection has the characteristics of small damage to crops and high utilization rate of pesticides. More and more farmers or farmers use drones for plant protection operations, especially for pesticide spraying and fertilizer spraying. [0004] Existing agricultural plant protection UAV operati...

Problems solved by technology

[0006] If the fruit tree crops are sprayed in the way of autonomous flight with specified line spacing and scanning spraying, due to the dense leaves of the crops and the large coverage area, the amount of effective adhesion that can be achieved in one flight is very small, and it cannot even reach the interior of the vegetation.

[0007] The method of spraying fruit tree crops by manual remote control UAV can make up for the shortcomings of autonomous flight scanning spraying, but due to the high growth of fruit trees and the large coverage area, it is very easy to block the operator's sight, which is easy to cause mistakes and accidents

During the operation, the operator needs to pay full attention to avoid operating errors, so the operator must have skilled operating techniques and rich experience, which leads to extremely high labor costs

During manual work, it is difficult for the operator to control the amount of spraying, and the effect of precise spraying cannot be achieved, and it is easy to cause too little or too much spraying
