Title:
SOWING DEVICE AND CONTROL METHOD THEREFOR, AND PLANT PROTECTION UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/119224
Kind Code:
A1
Abstract:
A method for controlling a sowing device. The method comprises: acquiring a target opening of a discharge port and a target rotational speed of a rotary table; obtaining a safe rotational speed of the rotary table according to the target opening; and controlling the rotational speed of the rotary table the next time and the opening of the discharge port according to the target rotational speed and the safe rotational speed. According to the control method of the present invention, the safe rotational speed of the rotary table is obtained by means of the obtained target opening of a discharge port, and the rotational speed of the rotary table of the sowing device next time and the opening of the discharge port are controlled according to the target rotational speed and the safe rotational speed, so that the sowing process can be controlled more precisely, thereby avoiding the problem of blockage of the discharge port caused by the mismatch between the target rotational speed of the rotary table and the target opening of the discharge port. Further provided are a sowing device and a plant protection unmanned aerial vehicle.
