Broadcast sowing control method, broadcast sowing control device, unmanned aerial vehicle and storage medium

Abstract

The embodiment of the invention discloses a broadcast sowing control method, a broadcast sowing control device, an unmanned aerial vehicle and a storage medium. The broadcast sowing control method is applied to an unmanned aerial vehicle mounted with broadcast sowing equipment. The broadcast sowing control method comprises the steps that: the flight speed of the unmanned aerial vehicle is acquired according to a preset period in the process that the unmanned aerial vehicle broadcasts materials in a plant protection area; based on the flight speed, a target initial speed when the material falls from the broadcast sowing equipment in the current period is determined; and the broadcast sowing equipment is controlled to broadcast the materials to the plant protection area at the target initial speed. The initial speed when the material falls is determined according to the flight speed, and the falling time of the materials is determined according to the initial speed under the condition that the flight height is constant, so that the horizontal movement distance of the materials can be adjusted according to the falling time, and the horizontal movement distance is matched with the horizontal movement distance of the unmanned aerial vehicle, so that the materials are broadcasted to accurate positions, the problem that the materials are broadcasted unevenly due to changes of the flight speed is avoided, accurate broadcast of the materials is achieved, and the even broadcasting effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a sowing control method, a sowing control device, an unmanned aerial vehicle and a storage medium. Background technique [0002] With the development of drone technology, drones are widely used in material spreading due to their advantages of vertical take-off and landing and not being affected by terrain. [0003] When the UAV spreads materials and plant protection operations on the plant protection area according to the preset plant protection route, it is usually assumed that the UAV spreads the material with a fixed amount of sowing at a constant flight speed, and the movement of the material in the horizontal direction after falling from the UAV The distance depends on the flying speed of the drone and the falling time of the material. When the plant protection route is short and the number of routes is large, it means that the UAV flies at a lower speed at the beg...
