Embodiment 1

[0050] An embodiment of the present invention provides a power supply device, which can be set in a tethered drone to provide power for the tethered drone. Such as figure 2As shown, the power supply device includes a first power conversion module, a power storage module and a control module. Wherein, the control module is respectively connected with the first conversion module and the power storage module, and both the power storage module and the first power conversion module are connected with the motor of the tethered drone. at the same time figure 2 The motor and functional components connected to the power supply device included in the tethered UAV are also shown in .

[0051] Specifically, the first conversion module may be a DC / DC level power converter. The first conversion module can be respectively connected with the ground power supply device and the motor in the tethered drone. In practical applications, the first replacement module can be connected to the gro...

Embodiment 2

[0090] Based on the same inventive idea, such as Figure 5 As shown, the embodiment of the present invention provides a power supply method, the power supply method can be used in the first embodiment of the power supply device includes a power conversion module and a power storage module, the power supply device can be located in a tethered drone, and the power supply device Connected to the motor of the tethered drone. The power supply method includes the following steps:

[0091] S11: When starting the tethered drone, collect the first voltage of the power conversion module and the second voltage of the power storage module in the power supply device, and connect the power supply device to the ground power supply device.

[0092] In the embodiment of the present invention, the power supply device in the series of drones can be connected to the ground power supply device through a power supply cable to obtain the power provided by the ground power supply device, such as mai...

Embodiment 3

[0105] Based on the same inventive concept, the embodiment of the present invention provides a tethered drone, such as Image 6 As shown, the tethered UAV is provided with a motor and a power supply device, and the power supply device is the power supply device shown in Embodiment 1. The tethered UAV can provide working voltage through the electricity in the storage battery in the power supply device and / or the voltage in the power converter, so as to drive the motor.

[0106] In practical applications, according to the different flight states of the tethered UAV, different power supply methods can be used to supply power to it, which makes the power supply method more flexible. For the specific power supply mode, please refer to the corresponding contents and drawings in the first embodiment and the second embodiment above, and details will not be repeated here.

Abstract

The embodiment of the invention provides a power supply device, a power supply method and a tethered unmanned aerial vehicle, and aims to solve the technical problem that a power supply mode of the tethered unmanned aerial vehicle in the prior art is poor. The power supply device comprises: a first conversion module that is separately connected with a ground power supply device and a motor of thetethered unmanned aerial vehicle, and is used for converting a power supply provided by the ground power supply device into a working power supply of the tethered unmanned aerial vehicle; a power storage module that is used for storing the working power supply provided by the first conversion module; and a control module that is used for detecting a first voltage in the first conversion module and / or a second voltage in the power storage module, determining the flying state of the tethered unmanned aerial vehicle, and controlling the working state of the first conversion module and / or the power storage module according to the flying state of the tethered unmanned aerial vehicle, wherein if the first voltage is detected to be in a preset voltage range and the second voltage is greater thanor equal to the preset voltage during the takeoff phase, the first conversion module and the power storage module are controlled to jointly supply power to the motor so as to drive the tethered unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power supply device, a method and a tethered drone. Background technique [0002] As a high-altitude base station, the tethered UAV can carry various communication loads such as ad hoc network radio stations, cluster micro-base stations, and micro-base stations, forming a variety of flexible communication application configuration methods. Powered by ground generators, it stays in the air 24 hours a day. The system can be loaded by platforms such as trucks and ships, and supports manual control mode and automatic control mode (in manual control mode, the movement of the drone can be controlled by the joystick; in automatic flight mode, It can realize the automatic hovering of the UAV and the automatic following of the vehicle) Set the flight height through the ground station, support one-key take-off, one-key landing and recovery through the ground station, when the motion ...
