Problems solved by technology

[0004] Aiming at the above-mentioned defects in the prior art, the present invention provides a method to solve the problem that the operator in the prior art sets the flight speed and spray flow rate. If the flight speed and spray flow rate are not set properly, it often causes the drone The crops in a certain area have been sprayed, but the medicine has been used up; or the drone has completed the operation of a certain area ahead of time, but there is still a lot of medicine left; or the medicine is not sprayed uniformly, etc.

Embodiment 1

[0042] figure 1 It is a schematic flow chart of the spraying control method of the unmanned aerial vehicle provided by Embodiment 1 of the present invention, such as figure 1 As shown, the drone's spraying control method performs spraying operations on a specific area of ​​the ground, including:

[0043] Step 101, obtaining the flight distance from the start point to the end point of spraying by the UAV in a specific area.

[0044] Wherein, the flight distance may be acquired through a Global Positioning System (Global Positioning System, GPS for short). For example, the GPS coordinates of the spraying start point and the spraying end point can be determined through GPS, and then the flight distance from the spraying start point to the end point can be obtained.

[0045] Alternatively, the flight distance may also be pre-stored. For example, according to the specific area, a flight route can be preset in the UAV, which includes: the start point of spraying, the end point of...

Embodiment 2

[0061] This example is in figure 1 On the basis of the first embodiment shown, step 1031 is further explained. figure 2 The schematic flow chart of the spraying control method of the unmanned aerial vehicle provided for the second embodiment of the present invention, as figure 2 As shown, in the spraying control method, specifically, if the spraying flow rate is selected, then according to the total amount of material that the drone needs to spray (referred to as the total amount of material in the following embodiments), the selected spraying flow rate and The flight speed calculated from the flight distance includes:

[0062] Step 10311, obtain the selected spray flow rate.

[0063] Specifically, the selected spray flow rate can be preset and stored in the processor of the drone.

[0064] Or, it can be automatically corresponding according to the type of the spraying component. Specifically, the selected spraying flow rate can be determined according to the correspondin...

Embodiment 3

[0081] This example is in figure 1 On the basis of the first embodiment shown, step 1032 is further explained. image 3 The schematic flow chart of the spraying control method of the unmanned aerial vehicle provided for the third embodiment of the present invention, such as image 3 As shown, in the spraying control method, if the flight speed is selected, the spray flow rate is calculated according to the total amount of material to be sprayed by the drone, the selected flight speed and the flight distance, including:

[0082] Step 10321, obtain the selected flight speed.

[0083] The selected flight speed comes from any one of the following three ways: pre-stored, or sent by the speed input.

[0084] Wherein, if the selected flight speed is sent through the speed input piece, optionally, there may be multiple speed input pieces, and each speed input piece can send out corresponding flight speed information.

[0085] Of course, there can also be one speed input. When there...

Abstract

The invention provides a spraying control method of a drone. The method comprises steps of acquiring a flight distance from a spraying start point to a termination point in a specific region of the drone; selecting one of following two parameters: the flight speed and the spraying flow speed of the drone; if the flight speed is selected, calculating the spraying flow speed according to total quantity of substances that the drone needs to spray, the selected spraying flow speed and the flight distance; and if the spraying flow speed is selected, calculating the flight speed according to the total quantity of substances that the drone needs to spray, the selected spraying flow speed and the flight distance. According to the invention, problems can be avoided that drugs have been used up while the drone has not finished the crop spraying in a certain region caused by improper flight speed and improper spraying flow speed which are easily caused by the fact that an operator simultaneously sets the flight speed and the spraying flow speed, or too many drugs have been left over since the drone has finished operation in the certain region in advance.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a spraying control method of the unmanned aerial vehicle and the unmanned aerial vehicle. Background technique [0002] In recent years, agricultural modernization and precision agriculture have been developing continuously, and the development of agricultural machinery has provided great convenience for agricultural modernization. Operation tools based on unmanned aircraft provide efficient and convenient operation methods for agricultural modernization. [0003] In the spraying operation of UAVs in the prior art, the operator usually sets the flight speed and spraying flow rate, but if the flight speed and spraying flow rate are not set properly, it often results that the UAV has not finished spraying the crops in a certain area. , and the medicine has been used up; or the drone has completed the operation of a certain area ahead of time, but there is still a lot of med...
