Problems solved by technology

[0003] In the prior art, it is difficult for the drones flying in the air to rely on the airborne Global Positioning System (Global Positioning System, GPS) module and the remote control of the pilot to achieve complex automatic hovering at fixed points and heights.
Even if this operation can be realized, this kind of complex operation that requires extremely high pilot ability will inevitably be difficult to meet the market requirements in terms of operation time, efficiency, and performance, which limits the application of drones

Embodiment 3

[0046] Figure 4 It is a schematic flowchart of a tethered follow-up method provided by Embodiment 3 of the present invention. The tethered following method provided in this embodiment may be performed by the tethered following system in any of the foregoing embodiments. Such as Figure 4 As shown, the tethered following method provided by the embodiment of the present invention specifically includes the following operations:

[0047] S410. When the flying device is in the airborne state, the gyro sensor detects the inclination angle between the cable and the vertical direction, and sends it to the control board.

[0048] S420. The control board calculates the flight direction and flight speed of the flying device according to the tilt angle, and sends them to the flight control module.

[0049] Specifically, this operation may be that the control board calculates the flight direction of the flying device according to the tilt angle through a proportional-integration-differ...

The system and method realize precise following of the flight device for the mooring platform on the ground.

Description

technical field [0001] The embodiments of the present invention relate to the field of unmanned aerial vehicles, and in particular to a tethered follow-up system and method. Background technique [0002] At present, drones have broad application prospects in many aspects such as aerial photography, geological survey, high-voltage transmission line inspection, oil field pipeline inspection, highway management, and crop pesticide application. [0003] In the prior art, it is difficult for the unmanned aerial vehicle flying in the air to rely on the airborne Global Positioning System (Global Positioning System, GPS) module and the pilot's remote control operation to achieve complex automatic hovering at a fixed point and height. Even if this operation can be realized, this kind of complex operation that requires extremely high pilot ability will inevitably be difficult to meet the market requirements in terms of operation time, efficiency, and performance, which limits the appl...
