BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to an unmanned aerial system, and more particularly, to a method of controlling a flight of an unmanned aerial robot by measuring a propeller status of the unmanned aerial robot and an apparatus for supporting the same.

Related Art

An unmanned aerial vehicle generally refers to an aircraft and a helicopter-shaped unmanned aerial vehicle/uninhabited aerial vehicle (UAV) capable of flight and controlled by the induction of a radio wave without a pilot. A recent unmanned aerial vehicle is increasingly used in various civilian and commercial fields, such as image photographing, unmanned delivery service, and disaster observation, in addition to military use such as reconnaissance and an attack.

In addition, unmanned aerial vehicles for civilian and commercial use should be restrictively operated because construction of foundation such as various regulations, authentication and a legal system is insufficient, and it is difficult for users of unmanned aerial vehicles to recognize potential dangers or dangers that can be posed to public. Particularly, occurrence of collision accidents, flight over security areas, invasion of privacy and the like tends to increase due to indiscreet use of unmanned aerial vehicles.

Many countries are trying to improve new regulations, standards, policies and procedures with respect to operation of unmanned aerial vehicles.

SUMMARY OF THE INVENTION

The present specification provides a method of flying an unmanned aerial robot using a 5G system.

The present specification further provides a method of controlling a flight of an unmanned aerial robot by measuring a propeller status of the unmanned aerial robot.

The present specification further provides a method of analyzing a flight status of an unmanned aerial robot by determining whether the propeller has a failure according to a status of the measured propeller.

The present specification further provides a method of transmitting an analyzed flight status to a base station, receiving an instruction message instructing a specific operation according to a flight status from the base station, and performing a specific operation according to the received instruction message.

The technical problems of the present invention are not limited to the above-described technical problems and the other technical problems will be understood by those skilled in the art from the following description.

In an aspect, a method of analyzing a propeller status of a wireless aerial robot includes measuring status information related to the propeller status by a sensor of a propeller; determining whether an operation of the propeller is abnormal based on the status information; transmitting the status information and information on whether an operation of the propeller is abnormal to a control unit using a short range wireless communication means; and analyzing a flight status of the wireless aerial robot based on the status information and information on whether an operation of the propeller is abnormal by the control unit.

The status information may be measured based on at least one of torque, lift, and/or a vibration of the propeller, and the sensor may be an acceleration sensor.

The determining of whether an operation of the propeller may include comparing a value of at least one of the torque, the lift, and/or the vibration with a minimum value and a maximum value of each parameter; and determining whether the propeller erroneously operates according to whether each parameter is greater than the minimum value and is smaller than the maximum value.

If each parameter is greater than the minimum value and is smaller than the maximum value, the propeller may be determined to be normal.

If each parameter is smaller than the minimum value or is greater than the maximum value, the propeller may be determined to be damaged or to perform an erroneous operation.

When the propeller is determined to perform an erroneous operation, the method may further include transmitting the flight status to a base station using a wireless communication means; receiving instruction information instructing a specific operation from the base station based on the flight status; and performing the specific operation.

In another aspect, a wireless aerial robot includes a main body; a propeller for flying the main body and the wireless aerial robot; and a drone arm for connecting the propeller and the main body, in which the propeller includes a sensor for measuring status information related to a status thereof, a micro control unit (MCU) for determining whether an operation of the propeller is abnormal based on the status information, and a short range wireless communication unit for transmitting the status information and information on whether an operation of the propeller is abnormal to a control unit using a short distance wireless communication means, and the main body includes a control unit for analyzing a flight status of the wireless aerial robot based on the status information transmitted through the wireless communication means and the information on whether an operation of the propeller is abnormal.

The propeller may further include a battery for supplying power to the MCU and the sensor and a wireless charging receiving unit for charging the battery by a rotation of the propeller.

The MCU and the sensor, the battery and the wireless charging receiving unit may be disposed at different sides of the propeller to have symmetric structures, respectively.

The drone arm may include a wireless charging transmission unit for generating power through the wireless charging receiving unit.

The control unit may include an electronic stability control (ESC) and a flight controller (FC).

The battery may be a thin film battery.
