Embodiment 1

[0027] The invention includes: a multi-rotor UAV mother machine, a multi-rotor UAV sub-machine, and an electromagnetic adsorption device.

[0028] In this embodiment, the parent machine is an eight-rotor UAV as an example, and the sub-machine is a four-rotor, (it does not mean that the system is only applicable to the eight-rotor UAV parent machine and four-rotor sub-machine, but for better To express the principle of the system clearly, take the eight-rotor as an example).

[0029] Fix the electromagnetic adsorption device on the shaft below the motor of the main machine. The shaft length of the slave machine is less than half of the shaft length of the master machine, and there is a square iron sheet 4 with better magnetism above the central platform of the frame of the slave machine.

[0030] The electromagnetic adsorption device is composed of an electromagnet, a switch, a power supply and a controller, wherein the electromagnet is controlled by the controller to open and...

Embodiment 2

[0032] On the basis of above-mentioned technical scheme, the present invention can also be improved as follows:

[0033] By controlling the size of the sub-machine, except for the sub-machine under the rotor, the medium-sized sub-machine is suspended below the center plate of the main machine 1 by an electromagnetic adsorption device, and the control system and the electromagnetic adsorption device are the same as in the first embodiment. The beneficial effect of adopting the above-mentioned further scheme is that the diversity of the multi-rotor drone's master aircraft can be increased. There are three types of UAVs in one set, which is more convenient to use its own advantages to perform different tasks.

Embodiment 3

[0035] The base aircraft can carry any number of sub-aircrafts that are less than the number of rotors of the base aircraft. Because the flight control of the base aircraft has a self-stabilizing function, there is no need to worry about the center of gravity shift caused by the different numbers of the base aircraft. The control system and the electromagnetic adsorption device are the same as in the first embodiment. The beneficial effect of adopting the above-mentioned further solution is that the number of multi-rotor UAV sub-machines can be increased, so that more tasks can be completed within the same time and work efficiency can be improved.

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle sub-master machine system, which includes a main machine, N sub-machines, and N electromagnetic adsorption devices, where N is a natural number greater than 1; wherein, an iron sheet is arranged above the frame platform of the sub-machine, The electromagnetic adsorption device is installed under any rotor of the main machine and is fixedly connected with the motor shaft of the rotor. The electromagnetic adsorption device absorbs the iron sheet on the sub-machine, so that the sub-machine and the main machine are absorbed into one body. The invention also discloses a control method of the multi-rotor unmanned aerial vehicle master aircraft system. The use of UAV sub-machine system can not only realize the collection of data information at multiple locations at a certain time, but also ensure sufficient power storage for collection tasks. Compared with a single UAV, it has the outstanding advantage of high efficiency and is more practical. Strong, flexible control, easy disassembly advantages.

Description

technical field [0001] The invention relates to the technical field of multi-rotor UAVs, in particular to a sub-machine system of a multi-rotor UAV. Background technique [0002] Multi-rotor UAV is a kind of aircraft that is gradually becoming practical at present. It has the advantages of flexible maneuvering, quick response, unmanned driving, and low operation requirements. Loading multiple types of sensors on the multi-rotor UAV can realize real-time observation and transmission of data. At present, multi-rotor UAV technology focuses on the research of UAV stand-alone, and the research on multi-rotor UAV sub-machine is not in-depth. The multi-rotor UAV sub-machine system can well make up for the limitations and deficiencies of the single multi-rotor UAV. For the lack of endurance of multi-rotor UAVs, the drone's sub-machine system can achieve double the endurance, and the tasks that cannot be completed by a single UAV can be completed by the sub-machine. [0003] At pr...
