Problems solved by technology

[0003] Traditional UAV automatic storage devices are mostly used in flat and fixed environments. Considering the diversification of the working environment of tethered UAVs, the angle of the lifting platform of these automatic storage devices is fixed, and the flexibility is low, which cannot meet the needs of tethered UAVs at sea. lifting requirements

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] The invention includes a first-level platform driven by two stepping motor lifting modules, and a second-level parallel platform driven by four servo electric cylinders. The first-level platform and the second-level platform are connected by supporting legs, and the supporting legs and the platform are connected by hinges. The secondary platform is equipped with a tethered UAV bracket and a cable guide device. The secondary platform is also equipped with an acceleration sensor and an angular acceleration sensor. The primary platform and the base are connected by a stepping motor lifting module. An elastic material is contained under the bracket. There are four supporting legs in a square layout. Each supporting leg is driven by a separate servo electric cylinder. It can also be said that the servo electric cylinder forms the su...

Abstract

The invention provides a marine mooring unmanned aerial vehicle automatic storage device and a control system thereof. A driving unit comprises a stepper motor lifting module and servo electric cylinders; the stepper motor lifting module serves as a main lifting motor of the storage device and is responsible for lifting a main platform, and overall recovering the platform and an unmanned aerial vehicle into a storage box after the unmanned aerial vehicle lands; and the servo electric cylinders serve as auxiliary motors for the storage device to drive a parallel platform on the main platform so as to guarantee levelness and stability of the platform under the ocean wave environment and assist the unmanned aerial vehicle in landing. The parallel platform is driven by the four servo electric cylinders, over-positioning of the parallel platform is reduced, the internal loss of the system is reduced, the working space of the platform is enlarged, and the control difficulty of the parallel platform is lowered; and meanwhile, compared with a single-stage lifting system of a traditional storage device, the two-stage lifting platform combination mode is adopted to maintain the stability of the platform under the ocean wave environment under the premise of the large working stroke of the platform.

Description

technical field [0001] The invention relates to a parallel platform system, in particular to an automatic storage device and a control system for a moored unmanned aerial vehicle at sea. Background technique [0002] With the development and promotion of UAV technology, the problem of its battery life has become more and more prominent. In order to solve this problem, people choose to combine traditional UAV technology with tethered platform technology to form a tethered UAV. The automatic storage device is the basis for the work of the tethered UAV. The retractable effect of the automatic storage device will directly affect the working efficiency of the UAV and the adaptable working environment. [0003] Traditional UAV automatic storage devices are mostly used in flat and fixed environments. Considering the diversification of the working environment of tethered UAVs, the angle of the lifting platform of these automatic storage devices is fixed, and the flexibility is low,...
