The airbag module 200a is electrically connected to the control module 120 using a cable 234 and a connector 232. [

Therefore, the airbag module 200a of this embodiment handles the same function as that of Fig. That is, the airbag module 200a of this embodiment senses when the unmanned aerial vehicle 100a falls down on the water surface, and operates the airbag 202 under the control of the control module 120 or the controller (not shown) .

The airbag module 200, 200a of the present invention has a weight of about 10% of the weight of the unmanned aerial vehicle 100, 100a. For example, the airbag modules 200 and 200a may be 500 g, 1,000 g, 1,500 g, or the like, depending on the weight of the various unmanned aerial vehicles 100 and 100a. The airbag modules 200 and 200a of the present invention may be provided in various sizes and shapes corresponding to the sizes and structures of the unmanned aerial vehicle 100 and 100a.

The configuration and function of the airbag module will be described in detail with reference to FIGS. 3 to 5. FIG.

Fig. 3 is a perspective view showing the configuration of the airbag module shown in Fig. 2, and Figs. 4 and 5 are exploded perspective views showing the configuration of the airbag module shown in Fig.

3 to 5, the airbag module 200a according to the present invention includes a housing 210, a bracket 220, an interface 230, a detonator 204, an energization sensor 208, A sensor 209 and an airbag 202. The airbag module 200a further includes an ignition part fixing member 206 and a sensor cover 207. [

The housing 210 is composed of a case 212 which is opened on one side and forms a receiving space therein and a cover 214 which covers an opened one side of the case 212. A power supply terminal 205 and an interface 230 are installed on one side of the housing 210. The housing 210 is made of a plastic material such as a soft plastic, which is easy to be attached to the support 150 and can be easily separated from the cover 214.

At least one bracket 220 is fixedly coupled to the upper or lower surface of the housing 210. The bracket 220 is mounted on the support 150 of the unmanned air vehicle 100a to install the air bag module 200a on the unmanned air vehicle 100a.

The interface 230 is constituted by a cable 234 and a connector 232, which are electrically connected to the control module 120 to transmit mutually electrical signals. One end of the cable 234 is electrically connected to the energization sensor 208, the pressure sensor 209 and the detonator 204, and the other end is electrically connected to the connector 232. The interface 230 is connected to the interface (124 of FIG. 6) of the control module 120. Accordingly, the interface 230 electrically connects the airbag module 200a and the control module 120. [

The detonator 204 is fixed to the inside of the housing 210 using a bracket-type detonator fixing member 206. The detonator 204 ignites and explodes to operate the airbag 202 under the control of the control module 120 or when the energizing terminal 205 is energized. That is, the detonator 204 is ignited and exploded by the energization sensor 208, the pressure sensor 209, or the controller to operate the airbag 202 when the unmanned air vehicle 100a falls down on the water surface. The detonator 204 is ignited and exploded using, for example, high-pressure nitrogen gas, and supplies nitrogen gas to the airbag 202 through a filtration device (not shown) to inflate the airbag 202. At this time, the detonator 204 is operated by being supplied with power from the battery (129 of FIG. 6) of the control module 120 through the interface 230.

When the unmanned object (100a) falls on the water surface, the energization sensor (208) energizes two (+) and (-) energizing terminals (205) . The energization sensor 208 outputs a detection signal so that the ignition unit 204 is ignited when the energization terminal 205 is energized.

The pressure sensor 209 senses the impact pressure due to the intake shock when the unmanned air vehicle 100a falls. The pressure sensor 209 may be provided as an impact sensor that senses the impact of water on the water surface when the unmanned air vehicle 100a falls. The pressure sensor 209 transmits sensing information according to the impact pressure to the control module 120 through the interface 230.

The energization sensor 208 and the pressure sensor 209 are supplied with power from the battery 129 of the control module 120 to sense the presence or absence of an electric current and an impact pressure.

The sensor cover 207 divides an internal space of the housing 210 in which the energization sensor 208 and the pressure sensor 209 are installed to protect the energization sensor 208 and the pressure sensor 209.

When the unmanned object (100a) is brought to the surface of the water by any one of the energization sensor (208), the pressure sensor (209) and the remote control of the controller when the unmanned air vehicle (100a) 204, and is kept in a balloon state (air tightness) for at least 30 minutes.

The airbag 202 is made of a synthetic fiber material, for example, a material in which a high-strength special fiber material such as a fiberglass is combined with a vinyl material, or a material in which a PVC material, a PVC material, and a fiber material are combined . At this time, the airbag 202 operates differently from the airbag for an automobile. That is, in the case of an automobile airbag, since the air bag 202 of the present invention is required to maintain a buoyancy for at least 30 minutes or more, a fine hole It should be absent.

Although the configuration and function of the airbag module 200a have been described using the embodiment of FIG. 2, the airbag module 200 of FIG. 1 has substantially the same configuration as that of FIG. 2 except for the bracket 220. FIG.

FIG. 6 is a block diagram showing a part of the configuration of the unmanned aerial vehicle shown in FIGS. 1 and 2. FIG.

Referring to FIG. 6, the unmanned aerial vehicle 100, 100a includes a control module 120 and an airbag module 200, 200a.

The control module 120 includes a control unit 122, a driving unit 126, an interface 124, a wireless communication unit 128, and a battery 129. The airbag modules 200 and 200a include an interface 230, an energization sensor 208, a pressure sensor 209, a detonator 204 and an airbag 202.

The control unit 122 controls all operations of the unmanned aerial vehicle 100, 100a. The control unit 122 controls the power supply to the energization sensor 208, the pressure sensor 209 and the detonator 204 from the battery 129 via the interfaces 124 and 230. [ The control unit 122 controls the ignition unit 204 to ignite and explode when the unmanned air vehicle 100a is received by the pressure sensor 209 and the collision is not performed on the water surface when the unmanned air vehicle 100a falls. When the unmanned aerial vehicle 100 or 100a collides with the water surface, the control unit 122 receives a remote control signal from the control unit and controls the ignition unit 204 to ignite or explode. Also, although not shown in the drawing, the control unit 122 controls the camera to shoot an image, and controls the original data for the captured image to be stored in the memory.

The driving unit 126 drives the propellers 130 under the control of the controller 122 so that the unmanned aerial vehicles 100 and 100a fly.

The interface 124 is electrically connected to the interface 230 of the airbag modules 200 and 200a to transfer electrical signals between the airbag modules 200 and 200a and the control unit 122, Power is supplied to the modules 200 and 200a.

The wireless communication unit 128 receives the remote control signal from the controller through the wireless communication network and provides the control unit 122 to fly the unmanned air vehicle 100 or 100a or to operate the air bag 202. [

Therefore, when the unmanned air vehicle 100 or 100a collides with the water surface, the ignition unit 204 is ignited and exploded by the energization sensor 208, the pressure sensor 209 or the manipulator, By operating the airbag 202, the unmanned aerial vehicle 100, 100a can be easily recovered.

And FIG. 7 is a flowchart illustrating a process for recovering unmanned aerial vehicles of the unmanned aerial vehicle according to the present invention. This procedure is a program that is processed by the control unit 202 of the unmanned aerial vehicle 100, 100a, and this program is stored in a memory (not shown) of the control unit 202. [

Referring to FIG. 7, in the unmanned air vehicle body collecting apparatus of the present invention, when the unmanned air vehicles 100 and 100a fall down in the step S300 and the unfiltered surface occurs on the water surface, in step S302, (208) is energized by the water through the energizing terminal (205) at the time of arrival. When the energization sensor 208 senses the energization as a result of the determination, the procedure proceeds to step S304 where the energization sensor 208 ignites and explodes the detoxification unit 204 to operate the airbag 202. [ However, if it is determined that the energization sensor 208 is not energized, this procedure goes to step S306.

In step S306, when the pressure sensor 209 of the airbag module 200, 200a falls, it is determined whether an impact pressure due to the intake shock is detected. As a result of the determination, if an impact pressure is detected from the pressure sensor 209, the procedure proceeds to step S308, where the control unit 122 ignites and explodes the detonator 204 to operate the airbag 202. [ However, if it is determined that the pressure sensor 209 does not detect an impact pressure, the procedure goes to step S310.

In step S310, since the drop is not detected in both the first and second vehicles in accordance with the falling condition, the controller remotely controls the unmanned air vehicle 100, 100a so that the air bag 202 is operated using the controller (not shown) . Then, in step S312, the control unit 122 ignites and explodes the detonator 204 in response to the remote control of the controller to operate the airbag 202. [

As described above, in the unmanned air vehicle recycling apparatus of the present invention, when the unmanned aerial vehicle 100 or 100a unexpectedly crashes during normal flight, the energization sensor 208 detects an accident and operates the airbag 202 . However, when the primary sensing failure is not detected by the energization sensor 208, an accident is sensed through the pressure sensor 209 and the airbag 202 is operated. The secondary pressure sensor 209 senses an impact pressure such as a water pressure when falling into the water, so that the possibility of operation of the airbag 202 can be increased.

However, when the sensor is malfunctioning or failing to detect the sensor by the primary or secondary sensor, the controller may directly control the unmanned air vehicle 100 or 100a in the control unit so that the detonator 204 is ignited or exploded to operate the air bag 202 have. As a result, the unmanned aerial vehicle 100, 100a can be easily recovered in a short time and without losing.

While the present invention has been shown and described with reference to certain embodiments thereof, it will be understood by those of ordinary skill in the art that various changes and modifications may be made without departing from the spirit of the invention. This is possible.
