Document Type and Number:
WIPO Patent Application WO/2019/119225
Kind Code:
A1
Abstract:
A control method for a sowing apparatus, comprising: acquiring a target degree of openness and the real-time degree of openness of a material outlet; determining whether the degree of openness of the material outlet is abnormal on the basis of the comparison result of the real-time degree of openness and the target degree of openness; and when the degree of openness of the material outlet is abnormal, transmitting an alarm signal to a remote control device. The control method of the present invention, by acquiring the target degree of openness and the real-time degree of openness of the material outlet, determines whether the degree of openness of the material outlet is abnormal with the comparison result of the two, and transmits the alarm signal to the remote control device when the degree of openness of the material outlet is abnormal, thus facilitating a user to learn in a timely manner information on the abnormal degree of openness of the material outlet and, at the same time, to take different targeted measures on the basis of different situations of the abnormal degree of openness so as to ensure that the uniformity of sowing is not affected by the abnormal degree of openness. Also provided in the present invention are the sowing apparatus and a plant protection unmanned aerial vehicle.
