Device and method suitable for fixed-wing unmanned aerial vehicle to land on field crop canopy

Abstract

The invention discloses a device and method suitable for a fixed-wing unmanned aerial vehicle to land on a field crop canopy. The device comprises a fixed supporting frame, a load buffering device and a pay-off and take-up device, wherein the fixed supporting frame comprises an underframe and a plurality of hanging brackets; the landing device is mounted under the unmanned aerial vehicle through the hanging brackets; the underframe comprises front end brackets, supporting side arms, a supporting front rod, a supporting middle rod and a supporting rear rod; one ends of the front end brackets are connected with the supporting side arms end to end; the other ends of the front end brackets are vertically connected with the supporting front rod; the supporting middle rod is respectively connected with front ends of the supporting side arms at the two ends; the two ends of the supporting rear rod are respectively connected with the tail ends of the supporting side arms on the two sides; the load buffering device comprises a glass fibre mesh and a sliding rod; one end of the glass fibre mesh is fixed on the supporting middle rod; the other end of the glass fibre mesh is fixed on the sliding rod; the sliding rod is parallel to the supporting front rod; and the sliding rod moves forwards and backwards along the supporting side arms under the driving of the pay-off and take-up device. The invention can ensure that the fixed-wing unmanned aerial vehicle can safely land on the field crop canopy without affecting the normal flight of the fixed-wing unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a field crop canopy landing device and method suitable for fixed-wing unmanned aerial vehicles. Background technique [0002] At present, drones are playing an incomparable role in agricultural production, such as widely used pesticide spraying operations. In addition, due to its advantages of lightness, flexibility, and ease of use, the UAV can carry sensors to detect and analyze field crop growth information, soil moisture and nutrition status, etc., so as to realize precise control of agricultural production. Once problems are found, they can be taken in time. Countermeasures to save resources and reduce losses. [0003] The main types of UAVs used in agricultural production are multi-rotor, single-rotor, and fixed-wing aircraft. When multi-rotor and single-rotor drones are operating in the field, they cannot guarantee long-term battery life due to their own w...

AI Technical Summary

Problems solved by technology

Due to field terrain factors, as well as the complex structure and heavy weight of the original landing gear, it is not suitable for agricultural production operations. Therefore, a landing device with light weight and simple structure is sought to realize the fixed-wing UAV in the field. The landing of the canopy is a useful supplement to the current agricultural aviation application technology
