Problems solved by technology

The presence of sideslip will cause the UAV to deviate from the take-off direction, resulting in unstable take-off; if it is serious, it will cause the aircraft to rush out of take-off and run, causing damage to the aircraft

Embodiment Construction

[0028] Now aiming at the actual measurement application of a domestic unmanned aerial vehicle sliding sideways, combined with the manual attached Figure 1 to Figure 3 Further describe the technical scheme of the present invention:

[0029] The domestic UAV has the following characteristics: the diameter of the tire on the landing gear is about 30cm, the hub of the tire is integrated, and the brake disc is fixed on the hub with three metal bolts; If there is a slight crosswind in the process, the UAV is very prone to roll and skid. In this embodiment, the critical speed of the tires for the takeoff and landing of the UAV is between 1800r / min-1900r / min , In addition, the flying speed of the UAV is not high.

[0030] Such as figure 1 As shown, a UAV sliding side deviation detection device includes two inductive wheel speed sensors that can directly measure the tire speed when the UAV is sliding, and a central processing circuit that receives and processes the wheel speed senso...

Abstract

The invention relates to an unmanned aerial vehicle ground sliding lateral deviation detection method and device. The unmanned aerial vehicle ground sliding lateral deviation detection device comprises a central processing circuit, wheel speed sensors and a plurality of sensed bolts used for fixing brake friction discs to wheel hubs and distributed evenly. The wheel speed sensors comprises the left wheel speed sensor and the right wheel speed sensor which are fixedly connected to undercarriages on the two sides of an unmanned aerial vehicle correspondingly, and the left wheel speed sensor and the right wheel speed sensor are arranged at certain intervals relative to the sensed bolts. Through the unmanned aerial vehicle ground sliding lateral deviation detection method, ground sliding lateral deviation of the unmanned aerial vehicle in the takeoff and landing processes can be detected rapidly, accurately and directly, and real-time communication with an unmanned aerial vehicle flight control system can be achieved in time, so that the aircraft ground sliding gesture is corrected in time, and operation safety of the unmanned aerial vehicle is ensured.

Description

technical field [0001] The present invention relates to the field of detection devices, in particular to a method and device for detecting sideways movement of a drone. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft operated by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device and other equipment. The personnel on the ground, on the ship or at the remote control station of the parent aircraft can track, locate, remote control, telemetry and digital transmission through radar and other equipment. It can also be taken into the air by the mother plane for flight. When recovering, it can automatically land in the same way as the landing process of ordinary aircraft; UAVs have a wide range of applications. Although they are not the main force for executing aerial characters on the battlefield in military terms, they have also be...
