Abstract

Provided is a control method of a sowing device. The method includes steps: obtaining a target openness and a real-time openness of a discharging port; determining whether the openness of the discharging port is abnormal according to a comparison result of the real-time openness and the target openness; and if yes, transmitting an alarm signal to a remote control device. According to the control method, the target openness and the real-time openness of the discharging port are obtained, whether the openness of the discharging port is abnormal can be determined through the comparison result ofthe target openness and the real-time openness, and the alarm signal is transmitted to the remote control device if the openness of the discharging port is abnormal so that a user can conveniently grasp information of the abnormal openness of the discharging port in time, target measures can be taken according to different conditions of abnormal openness, and the influence of the abnormal opennesson the sowing uniformity is avoided. The invention also provides a sowing device and a plant protection unmanned aerial vehicle.

Description

technical field [0001] The present invention relates to the control of sowing materials by a plant protection drone, in particular to a sowing device, a control method thereof, and a plant protection drone. Background technique [0002] Plant protection UAV is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of UAV can realize long-distance remote control operation, and can also avoid manual operations with high labor intensity, low efficiency, and uneven sowing density. Problems such as uniformity are becoming more and more popular among agricultural producers. [0003] Existing plant protection UAVs include a flying platform (fixed wing, helicopter, multi-axis aircraft) and a spreading device mounted under the flying platform. Through ground remote control or navigation flight control in the flying platform, the seeds, Spreading of solid particles such as medicaments and fertilizers. The spreading device capable of spreading ...
