Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] At present, the traditional method of detecting whether the aircraft has landed is to detect the height of the aircraft through an on-board altitude sensor, and the reliability of the determined detection results is poor. The embodiment of the present invention provides a method for detecting the landing of an aircraft. The method obtains the attitude data of the aircraft, and...

Abstract

The present invention provides a method and a device for detecting the aircraft landing. The method comprises the steps of acquiring aircraft attitude data collected by an attitude sensor, wherein the aircraft attitude data are used for characterizing the action states of an aircraft and the action states are composed of one selected from the air flight state and the ground landing state; analyzing the aircraft attitude data to obtain the amplitude-frequency characteristics of the aircraft attitude data; according to the amplitude-frequency characteristics, determining the action state of the aircraft. According to the amplitude-frequency characteristics of the aircraft attitude data, the action state of the aircraft is determined. Therefore, the influence of various noises and interferences on the aircraft attitude data in the time domain can be avoided, so that the action state of the aircraft is determined more reliably and more accurately. Meanwhile, based on the above reliable determination result, a corresponding control strategy is conducted for the above aircraft, and the adopted control strategy is more accurate. The technical problem in the prior art that the traditional aircraft landing detection method is poor in reliability can be relieved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a method and device for detecting the landing of an aircraft. Background technique [0002] When the multi-rotor aircraft is in the state of landing on the ground or in the state of flying in the air, different control strategies need to be adopted respectively to ensure the safety of the aircraft on the ground and the stability of the air flight. Therefore, it is very important for the flight control system of the aircraft to accurately detect whether the aircraft has landed. [0003] Due to cost constraints, consumer aircraft (for example, aerial photography machines, plant protection drones, etc.) usually use airborne altitude sensors (for example, barometers, GPS, etc.) to detect whether the aircraft has landed. However, the detection accuracy of airborne altitude sensors Limited, it cannot achieve the accuracy required for aircraft landing detection. Therefore, the result...
