Unmanned aerial vehicle-based spray sprinkling control method and control device

Abstract

The invention discloses an unmanned aerial vehicle-based spray sprinkling control method and control device. The control method comprises the following steps that: an unmanned aerial vehicle is controlled to perform spray sprinkling work according to preset flight trajectories; corresponding relations between the actual flight trajectories of the unmanned aerial vehicle and the preset flight trajectories are monitored; and if it is judged that the actual flight trajectories deviate from the preset flight trajectories, the unmanned aerial vehicle is automatically controlled to stop the spray sprinkling work. According to the unmanned aerial vehicle-based spray sprinkling control method and control device of the invention, as for a condition that an unmanned aerial vehicle does not fly according to preset flight paths and is even out of control, the problem of influence on the growth of crops caused by improper dosage sprinkling at local regions can be solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle-based spraying control method and control device. Background technique [0002] At present, the multi-rotor UAV has been greatly developed, and it is favored by both the professional market and the consumer market. The reason why the multi-rotor unmanned aerial vehicle can be developed so rapidly is that the progress of related electronic technology has made the cost of this kind of aircraft rapidly reduced, and at the same time, the safety has been rapidly improved. [0003] Because of its ability to take off and land vertically, flexible flight, and mature control methods, some people have begun to apply it to the field of plant protection; the most important way to use unmanned aerial vehicles in the field of plant protection is to use unmanned aerial vehicles equipped with storage There are spray containers and spraying devices, an...

Problems solved by technology

But one problem is that the spraying route of the spray is often pre-planned, and the best spraying effect can be achieved through the pre-planned route

However, if the unmanned aerial vehicle fails to fly according to the pre-planned route or even has a flight out of control, at that time, it may be possible to regain control of the drone through the control of the pilot, but the control of spraying is often lacking in timeliness and effectiveness , which will lead to the spraying of the spray beyond the pre-designed range, resulting in improper spray dosage in local areas and affecting the growth of crops

[0007] However, the problem in the above-mentioned scheme is that no matter the GPS navigation control mode or the manual control mode, when the unmanned aerial vehicle loses control in flight or temporarily loses control, there is no way to control the spraying equipment well in time, which leads to Improper spraying of sprays, especially the problem of excessive spraying
