Embodiment Construction

[0027] A method for self-adaptive and precise pesticide application by unmanned aerial vehicles, such as figure 1 shown, including the following steps,

[0028] Step 1: Use the GPS positioning system to plan at least one rectangular area for UAV operation and UAV navigation trajectory 1 .

[0029] The operation area is the area to be sprayed, which is the crop growth area 2. The system divides the area to be sprayed into several rectangular areas, and determines the positions of four points in the rectangular area.

[0030] Plan the track line according to the position of four points. Plan flight altitude, flight speed and flight time according to crops and obstacles.

[0031] Step 2. Enter the parameter values ​​of this flight defense operation in the software system, including:

[0032] Determine the four-point GPS positioning (automatically calculate the operating area) position in the rectangular area, the average flight speed V (m / s), and the flight height. Calculate ...

Abstract

The invention discloses a self-adaption precise pesticide applying method of an unmanned aerial vehicle, and belongs to the technical field of agricultural plant protection mechanical automation. The method comprises the following steps that a GPS is started, the area to which pesticide is about to be applied is divided into one or more rectangular areas through the system, and the unmanned aerial vehicle track line is planned according to the four-point positions of the rectangular areas; parameter values of flying protection work are input into the system, and the parameter values comprise the operation area, average flight speed and the pesticide applying standard range [F1, F2]; a wireless sensor node is arranged in the spraying operation area; a central control node in communication with the wireless sensor node is mounted on the unmanned aerial vehicle; the unmanned aerial vehicle is started, and the unmanned aerial vehicle carries out pesticide applying when flying to the starting point position in the four points of the rectangular areas according to the planned track line. By means of the self-adaption precise pesticide applying method, the autonomous flight capacity of the plant protection unmanned aerial vehicle in precise pesticide applying operation is improved, the problem of uneven spraying caused by objective factors of the plant protection unmanned aerial vehicle is solved, and the operation effect and operation yield of the plant protection unmanned aerial vehicle are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery automation, and in particular relates to a method for using wireless sensor network technology to precisely apply pesticides to farmland crops by drones. Background technique [0002] In recent years, the application of drones in the field of agricultural plant protection in my country has become more and more extensive. With the maturity of technology, drones are gradually gaining more room for development in crop spraying, and are being used by more and more agricultural producers. The recognition has also further improved the level of mechanization of agricultural plant protection in my country. Although UAVs have great advantages in plant protection mechanized operations, they still need continuous improvement in the development process. [0003] The uniformity of pesticide application to crops is an important indicator for testing UAV flight defense operations....
