Method and device for adjusting broadcasting amount, unmanned aerial vehicle and storage medium

Abstract

The embodiment of the invention discloses a method and device for adjusting broadcasting amount, an unmanned aerial vehicle and a storage medium, which are applied to the unmanned aerial vehicle for broadcasting by driving a material taking wheel through a motor; the method comprises the following steps: receiving calibration instructions including a calibration rotation speed and calibration duration; controlling a motor to operate at the calibration rotation speed within the calibration duration so as to discharge materials to be broadcast; acquiring flight parameters and the actual discharge amount of materials to be broadcast discharged by a material taking wheel in the calibration duration; determining an adjustment coefficient of the flight speed and the rotation speed of the motor according to the flight parameters and the actual discharge quantity; adjusting the rotation speed of the motor according to the adjustment coefficient so as to adjust the broadcasting amount. In the calibration stage, different materials to be broadcast are controlled to be discharged by controlling the motor to operate the calibration duration at the calibration rotation speed, so that the flightspeed and the motor rotation speed adjustment coefficient can be obtained, the rotation speed of the motor driving the material taking wheel under different flight speeds of different broadcast materials is achieved, and accurate variable broadcast is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for adjusting the amount of sowing, a device for adjusting the amount of sowing, an unmanned aerial vehicle and a storage medium. Background technique [0002] With the development of drone technology, drones have the advantages of vertical take-off and landing and are not affected by terrain, making it possible for drones to sow seeds. [0003] In the plant protection drone that spreads materials, the spreading device is mounted on the drone, and the spreading device drives the reclaiming wheel to discharge materials through a motor to realize material spreading. After setting the amount per unit area of ​​the UAV, the motor speed is usually fixed, and the UAV spreads materials according to the set flight speed, flight height and preset flight route. However, due to the influence of the external environment, the UAV The flight speed of the drone cannot...
