Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] Such as figure 1 , figure 2 Shown, the method for continuously spraying pesticides by unmanned helicopter is divided into the following steps;

[0025] In step 101: set a moving H point on an edge of the farmland, and set the edge as a reference edge;

[0026] In step 102; the unmanned helicopter takes off from point H, and sprays pesticides along a straight line perpendicular to the reference side;

[0027] In step 103; after the unmanned helicopter has sprayed the pesticide at point E, utilize GPS to record the latitude and longitude of said point E, utilize the barometer to record the height of point E, and utilize the electronic compass to record the a...

Abstract

The invention discloses a method for continuously spraying pesticide by an unmanned helicopter, which comprises the following steps that: one edge of a piece of land is provided with a moving point H; the unmanned helicopter takes off from the point H and sprays the pesticide along parallel straight lines; after the pesticide spraying completion by the unmanned helicopter at a point E, the longitude and latitude of the point E are recorded by a global positioning system (GPS), the height of the point E is recorded by a barometer, and the azimuthal angle data of the point E is recorded by an electronic compass; and the unmanned helicopter automatically flies back to the point E for continuously spraying the pesticide according to the longitude and latitude, the height and the azimuthal angle data of the point E recorded by the GPS, the barometer and the electronic compass after the unmanned helicopter returns to the point H to load the pesticide. The goal of preventing missed spraying or repeated spraying is realized, and the continuous pesticide spraying operation is formed.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for continuously spraying pesticides or fertilizers by an unmanned helicopter. Background technique [0002] The invention with the application number 201010178360.2 discloses an unmanned helicopter for spraying pesticides, using a central controller to control the power unit and the drug pump to spray the pesticides. The utility model has a simple structure and can automatically spray pesticides, which brings convenience to agricultural production. Due to the limited weight of unmanned helicopters carrying pesticides. After each spraying is completed, it is necessary to return to the ground to replenish pesticides. However, there are no obvious reference marks in many farmlands, and it is difficult for operators to remember the geographical location and direction of the unmanned helicopter that sprayed the last time. And in the invention that application number is 20101050...
