Description

Unmanned aerial vehicle having apparatus for control take off

The present invention relates to an unmanned aerial vehicle, and more particularly, a take-off control that can dramatically improve the flying distance of an unmanned aerial vehicle by enabling stable aerial take-off of a baby drone from a mother drone in flight It relates to an unmanned aerial vehicle equipped with a device.

Recently, multinational IT companies such as Google and Amazon are focusing on services using drones. For example, the field of application is very wide, such as an unmanned delivery system, a monitoring system, and a filming system. As commercial drones develop in this way, commercial demand, which accounted for only 1% of the total drone market in 2016, is expected to expand to 7% by 2023.

In general, a drone refers to an unmanned aerial vehicle, and recently, in particular, a multi-rotor type unmanned aerial vehicle is referred to as a drone.

Drones are not only unmanned aerial vehicles, but also have the characteristics of being able to hover because they are rotary wing unlike fixed-wing drones. In addition, since the size of the rotor is a small multi-rotor type, it is more stable and safer than a helicopter having a single rotor.

Moreover, since it is based on a motor rather than an engine, the control performance is excellent, and the noise is relatively low, so it is in the spotlight for its utilization. That is, since it operates as a small multi-rotor, it is relatively safe and has the advantage of being easy to operate in a complex environment such as a city center.

In addition, since drones are closer to robots than traditional aircraft, it is relatively easy to incorporate information and communication technologies such as the Internet of Things (IoT). For example, since it is very easy to attach and detach other equipment such as a camera, it has already been used for photographing or monitoring work using the same.

However, the biggest weakness of drones is their operating time, as drones are battery-powered with motors. In the case of a typical drone, it is easy to operate over 20 minutes.

is not Moreover, the drone is small in size and battery type, so the payload is also small.

In addition, since the drone is a multi-rotor type, there is a problem in that it is vulnerable to disturbances compared to a large one-rotor. In order to be strong against disturbances, the size of the drone must be increased. Due to these problems, it is not easy to use drones, especially between high-rise buildings in urban areas where there is strong disturbance or when performing missions in mountainous areas. For example, in the event of a fire in a high-rise building, it is necessary to monitor the situation at the scene before rescuers enter and deploy drones to obtain information about the survivors. However, the problem is that if the size of an indoor drone is large, it must be small because it is a safety problem in the event of an accident. In addition, in order to secure the operating time of the drone, it is necessary to save the battery, and even if it can go up to a high floor, the battery consumption is very severe, so it is difficult to perform a desired task for the required time in a high-rise building.

Therefore, a carrier drone technology consisting of a parent and child drone that can reliably access disaster sites located on high floors from the outdoors such as high-rise buildings and can enter indoors and perform missions smoothly has been developed.

However, this carrier drone technology is a technology that enables the combination and separation of the child drone from the parent drone using a pneumatic method. In the case of separation in an unobtainable situation, the take-off of the self-drone does not occur smoothly, and this has a problem in that the self-drone crashes together with the parent drone.

A take-off operation in the take-off space 200 of the own drone 20 from the mother drone 10 configured as described above will be described below.

5 is a block diagram showing the take-off operation of the own drone 20 from the parent drone 10 of an unmanned aerial vehicle equipped with the take-off control device according to the present invention, wherein the parent drone 10 and the child drone 20 are in flight. When the self drone 20 is to be separated in the air, in the take-off standby state, the self drone 20 disposed on the mounting plate 12 has a magnetic part 31 and a magnetic part 21 coupled by magnetic force. be in a state At this time, since the movable contact 33a and the fixed contact 33b are spaced apart from each other by the elastic force of the elastic body 32 , power is not provided to the magnetic part 31 . That is, the magnetic unit 31 provides the magnetic force of the permanent magnet to pull the self-propelled unit 21 and the magnetic drone 20 provided with the dissipating unit 21 to maintain a fixed state.

In such a state where the autonomous drone 20 for the parent drone 10 is waiting for take-off, when the controller operates the remote controller to operate the own drone 20, as shown in FIG. 3 , the own drone 20 As the rotor 20a rotates, the lift force is gradually generated.

When the drone 20 takes off in a state in which lift is generated, the lift force increases and overcomes the elastic force of the elastic body 32 pulling the magnetic part 31 downward, and the magnetic part 31 and the pizza magnetic part 21 The sleeping drone 20 rises in the attached state.

As the self drone 20 rises, the movable contact 33a comes into electrical contact with the fixed contact 33b, and the switch is turned ON.

Then, when a separate power is applied to the magnetic part 31 by the electrical contact of the contact part 30, antimagnetic force that cancels the magnetic force of the permanent magnet is generated to remove the magnetic force, so the drone 20 By removing the magnetic force pulling the magnetic part 31 and the magnetic part 21 are separated, the magnetic drone 20 is able to fly in the air.

On the other hand, the flight control device measures the lift of the own drone 20 to determine whether sufficient lift is reached for take-off. The lift of the own drone 20 overcomes the elastic force of the elastic body 32 and the movable contact 33a. When the magnetic force is removed from the magnetic unit 31 by contacting the fixed contact point 33b, the autonomous drone 20 reaches sufficient lift to determine that it can take off from the take-off space unit 200 .

When the take-off of the magnetic drone 20 is successful, the magnetic coupling between the magnetic part 31 and the magnetic part 21 is resolved, and the magnetic part 31 is moved downward by the elastic force of the elastic body 32 . When the connection of the contact part 33 is released, the power supply to the magnetic part 31 is cut off and the antimagnetic force that cancels the magnetic force of the permanent magnet is removed, so that the magnetic force of the permanent magnet is maintained again. .

Even if magnetic force is generated in the magnetic unit 31 of the take-off control unit 30 as described above, when the take-off of the own drone 20 succeeds and flies, the self-propelled unit 21 of the own drone 20 is the parent drone 10. There is no possibility of being attached to the magnetic part 31 . However, when the self-drone 20 fails to take off, the self-propelled part 21 of the self-drone 20 can be coupled by the magnetic force of the magnetic unit 31 of the take-off control unit 30, so the self-drone 20 safe landing can be ensured.
