[0111] Based on the first embodiment, the present invention also proposes the second embodiment of the control method of the fixed-wing UAV with vertical take-off and landing function, such as image 3 As shown, step S50 also includes:

[0112] Step S501, obtain the current airspeed in real time through the airspeed meter of the drone.

[0113] At the nose position of the UAV, an airspeed meter is set to detect the airspeed of the UAV, and after the UAV takes off, the airspeed meter detects the current airspeed of the UAV in real time, and the current The airspeed is uploaded to the UAV's control center in real time.

[0114] Step S502, judging whether the current airspeed reaches the preset airspeed;

[0115] The control center of the UAV stores a preset airspeed. If the preset airspeed is set to 20m / s, when the current airspeed increases to 20m / s, it can be determined that the current airspeed has reached the preset airspeed.

[0116] Step S503, if yes, then control the f...

Abstract

The invention discloses a fixed-wing unmanned aerial vehicle with a vertical take-off and landing function, a control method and a medium. The control method includes the steps that after an air routeis planned and a take-off command is triggered, propellers of the unmanned aerial vehicle are controlled to rotate in a multi-rotor mode, so that the unmanned aerial vehicle vertically climbs; whether the unmanned aerial vehicle reaches a first preset condition or not is judged; if the unmanned aerial vehicle reaches the first preset condition, first rotors are controlled to conduct transitionaltilting on the basis of a first preset speed; whether the tilting angle of each first rotor reaches a preset angle or not is judged; and if the tilting angle of each first rotor reaches the preset angle, the unmanned aerial vehicle is controlled to fly in a fixed wing mode when the unmanned aerial vehicle is controlled to reach a preset air speed. The complex control problem in the mode switchingprocess is solved, the mode of the unmanned aerial vehicle can be stably switched, and the vertical take-off and landing advantage of the multiple rotors and the efficient cruising advantage of fixedwings are combined and brought into play.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fixed-wing unmanned aerial vehicle with a vertical take-off and landing function, a control method and a medium. Background technique [0002] In the field of UAVs, it can be divided into fixed-wing UAVs and multi-rotor UAVs according to the classification of wings. The two types of UAVs have their own advantages and disadvantages. [0003] Multi-rotor drones mainly rely on the lift generated by multiple rotors to balance the gravity generated by the aircraft itself, and control the attitude of the aircraft by changing the speed of each rotor. Generally, multi-rotor drones can hover or fly at any speed within a preset speed range. [0004] Fixed-wing UAVs mainly rely on the thrust generated by propellers or turbine engines as power, and their lift mainly comes from the relative motion between the wings and the air. Generally, fixed-wing UAVs must have a certa...
