Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] Such as figure 1 As shown, the flow diagram of the multi-rotor drone spraying control method of the embodiment of the present invention includes the following steps:

[0047] S101. Detect the flight speed and flight direction of the UAV; specifically, detect the flight speed and flight direction of the UAV through flight data detection technology. The flight data detection technology includes but is not limited to speed detection sensor technology, acceleration Sensing technology, electronic magnetic compass technology, etc. Preferably, first, the personnel control the drone to fly in one direction at a certain speed through the drone controller, and then the drone automatically triggers the detection, and finally, the flight data of the ...

Abstract

The invention discloses a method and system for spraying control of a multi-rotor UAV based on speed detection. The method includes the following steps: detecting the flight speed and direction of the UAV; Cross decomposition, determine the sub-velocity V1 towards the nose and the sub-velocity V2 in the transverse direction; according to the sub-velocity V1 towards the nose and the sub-velocity V2 in the transverse direction, control a part of the water pumps to turn on and turn off the other part of the water pumps. The beneficial effect of the method is that the plant protection materials are made to fall behind the UAV without falling on the UAV, so that the lifespan of the UAV is not shortened, the crops are not damaged, and the plant protection materials are saved. The system includes: a flight data detection unit, a vector decomposition unit, and a control unit. The beneficial effect of the system is to realize the control of the atomization degree of plant protection materials, and to adjust different fog particles according to different crops, so as to achieve the purpose of not damaging the crops.

Description

technical field [0001] The invention relates to the field of plant protection drones, in particular to a speed detection-based multi-rotor drone spraying control method and system. Background technique [0002] With the development of science and technology, the scale of agricultural land production is gradually advancing, but the shortage of rural labor runs counter to it, which affects the progress to a certain extent. Saving labor and being able to scale has become a common demand among agricultural practitioners. The use of drones for plant protection solves the problem of labor shortage, improves production efficiency, and reduces production costs. [0003] The method of plant protection through drones is: measure the plant protection operation area; design the distribution position of the energized guide rail poles according to the area of ​​the operation area; install the energized guide rail poles, energized guide rails and conductive sliders; connect the power suppl...
