1 is a schematic configuration diagram of a drone system according to an embodiment of the present invention.

Referring to FIG. 1, a drone system according to an embodiment of the present invention includes a drone 10, a mission device 100, and a docking station 200.

The drone 10 may be an unmanned aerial drone capable of flying or an underwater drone. In the case of aerial drones, it is possible to implement a fixed wing capable of vertical takeoff and landing, or a rotary wing method with multiple rotors, or a combination thereof. The drone 10 may be remotely controlled for flight by wireless communication with a user terminal. The drone 10 is provided with a camera and an infrared module on one side, so that it can be transmitted to a user terminal only to acquire an image during flight even day and night. The drone 10 is driven by forming a replaceable battery, and the battery can be charged and used in the form of a secondary battery. In this case, the drone 10 may be mounted on the docking station 200 to wirelessly charge the battery.

In addition, a connection plate in the form of an iron plate may be attached to the drone 10. This is a means for magnetic coupling with the mission device 100. In this case, a shielding film capable of shielding a magnetic field may be attached to the drone 10 or the surface may be coated with a paint of a magnetic field shielding component. As another example, the connection plate may be formed to be spaced apart from the drone 10 at regular intervals through a strap connected to the body of the drone 10. This is to prevent an error in the geomagnetic sensor of the drone 10 itself due to magnetic force generated when combined with the mission device 100.

In addition, the drone 10 flies to the target point under the control of the user terminal. In this case, the target point is a point that the mission device 100 must reach, and the area may be set by the geofence. The drone 10 attaches the mission device 100 to one side to fly to the target point, and the mission device 100 is separated from the target point to perform a mission at the target point. The drone 10 can wait at the docking station 200 and charges the battery during standby. The drone 10 may return to the position of the docking station 200 from the target point. In this case, the drone 10 may fly around the target point in order to determine whether the mission device 100 performs the mission at the target point.

The mission device 100 is formed in a detachable form on the drone 10. The mission device 100 is equipped with a function module capable of performing various tasks therein. For example, the mission device 100 may deliver items such as first aid medicine, emergency food, smoke bombs, GPS, etc. or deliver items to a remote location or when a distress accident occurs. In addition, the mission device 100 may extinguish a fire using a fire extinguishing liquid or rescue a person through a life-saving equipment. In addition, research devices such as communication repeaters and air pollution measuring devices may be installed. In addition, the mission device 100 may be used for military use by mounting a bomb. However, the mission device 100 may perform various other tasks.

In addition, the mission device 100 is automatically separated from the drone 10 at the target point by a control signal from the user terminal. In this case, the method in which the drone 10 and the mission device 100 are connected can be implemented in various ways. The mission device 100 supplies power through an internal battery to communicate with the user terminal or receives power that can be separated from the drone 10. The weight of the mission device 100 may vary depending on the performance of the drone 10.

In addition, the mission device 100 may be automatically attached to the drone 10 at the docking station 200. In this case, the drone 10 may combine the mission device 100 when charging is completed in the docking station 200. For example, the drone 10 is accommodated in the docking station 200, and when the charging of the drone 10 is completed or there is a mounting signal, the drone 10 is exposed to the outside and attached to one side of the drone 10. When the mission device 100 is separated from the drone 10, the function module accommodated therein is discharged to the outside under a preset condition to perform a function. The mission device 100 may discharge internal functional modules in response to a constant pressure, moisture, temperature, and the like.

The docking station 200 guides the take-off and landing of the drone 10. Docking station 200 The docking station 200 may be formed in the form of a street lamp or a post of a fence. The docking station 200 can guide the take-off and landing of the drone 10 by varying its height in a cylinder manner. The docking station 200 is implemented in the form of an electromagnet on the take-off and landing surface, so that the drone 10 can be firmly fixed by magnetic force. In this case, the drone 10 is preferably formed with an iron plate or a magnetic chuck. Accordingly, the drone 10 can be safely landed on a marine vessel or the like.

In addition, the docking station 200 may charge the drone 10 when the drone 10 lands by a wireless charging method. For example, the docking station 200 may wirelessly charge the drone 10 through inductive coupling using an inductor. When the docking station 200 is formed on a street light or a fence, it is also possible to supply power using a solar cell or a wind power generation method using renewable energy. Accordingly, it can be installed in areas where power supply is not smooth.

In addition, the docking station 200 may accommodate the mission device 100 therein. The docking station 200 may be attached to one side of the drone 10 by moving the mission device 100 when the drone 10 is ready for takeoff. This is to enable the user to automatically attach the drone 10 to the drone 10 without directly attaching the mission device 100 to the drone 10 even in a remote location. The docking station 200 detects the weight of the mission device 100, compares it to the performance according to the model of the drone 10, and mounts the mission device 100 on the drone 10 only when it is possible to fly. Can be.

2 is a configuration diagram of a drone detachable mission device using a magnet according to an embodiment of the present invention, and FIG. 3 is an exemplary view for explaining that a function module is discharged from the drone detachable mission device using a magnet according to FIG. 2 to be.

2 and 3, a drone detachable mission device 100 using a magnet according to an embodiment of the present invention includes a function unit 110, a connection unit 120, a communication unit 130, and a control unit 140 do.

The functional unit 110 is formed to accommodate a functional module 110-1 such as various items, fire extinguishing fluid, lifesaving equipment, weapons, communication equipment, air pollution level sensor, etc. inside the main body 111. The body 111 may be formed in a cylindrical capsule shape, but is not limited thereto. The functional unit 110 is connected to the drone and is separated from the drone after moving to the target point. For example, when the functional module 110-1 is a lifesaving device, the functional unit 110 is dropped from the ground at a certain altitude or higher, and one side of the body 111 is opened by pressure, so that the lifesaving equipment is withdrawn. have. For example, the functional unit 110 may be opened as the body 111 melts in a water-reactive type while contacting water. For example, in the functional unit 110, the main body 111 is formed of a heat-resistant material, so that the fire extinguishing liquid may be sprayed at the target point of the fire site.

In addition, the functional unit 110 may have an open/closed structure on one side of the main body 111. For example, the functional unit 110 may include a body 111, a cover 112, a link 113, and a first motor 114. The body 111 is a cylindrical body, and the function module 110-1 is accommodated therein. The cover 112 is a protective member closing one side of the body 111. The link 113 may be formed in a joint structure connecting the body 111 and the cover 112. The first motor 114 drives the link 113 to rotate the cover 112. In this case, while the cover 112 is rotated, one side of the main body 111 may be opened or closed.

In addition, the functional unit 110 may further include a push rod 115 and a second motor 116. The push rod 115 is a rod that moves inside the body 111. The push rod 115 serves to push the function module 110-1 to the outside of the main body 111. The second motor 116 drives the push rod 115 to advance or retreat. When the cover 112 is opened, the second motor 116 pushes the push rod 115 toward the open side to discharge the function module 110-1 to the outside. In this case, the first motor 114 and the second motor 116 may be implemented as one or may be implemented independently. The driving of the first motor 114 and the second motor 116 is controlled by the controller 140.

The connection unit 120 connects the functional unit 110 to the drone. For example, the connection part 120 is formed on one side of the functional part 110 and is attached to and detached from the drone. The connection unit 120 may be implemented by any one or more of a Velcro connection method, a ring connection method, an electromagnet connection method, and a switch magnet connection method in which the functional unit 110 can be attached to and detached from the drone, but is not limited thereto. . The connection unit 120 may connect the functional unit 110 to the drone in a variety of ways in a horizontal direction, or may be connected in a vertical direction. This may be set differently according to the type and role of the functional module 110-1.

In addition, after the connection part 120 is fixed to the drone, it is possible to separate only the functional part 110. One side of the connection part 120 may be formed in a detachable type with the drone, and the other side may be formed in a detachable type with the functional part 110. For example, when the functional unit 110 is a throwable type such as digestive fluid, only the functional unit 110 may be separated from the target point. The connection part 120 is implemented by any one or more of a Velcro connection method, a ring connection method, an electromagnet connection method, and a switch magnet connection method when connected to the drone, and a Velcro connection method or a ring when connected to the functional unit 110 It may be connected by any one or more of a connection method, an electromagnet connection method, and a switch magnet connection method. Accordingly, the drone can return after completing the mission at the target point, mount another function unit 110 to quickly move to the target point, and reduce cost by reusing the connection unit 120.

FIG. 4 is an exemplary view for explaining the implementation of the connection part in a ring connection method in the drone detachable mission device using a magnet according to FIG. 2.

2 and 4, when the connection part 120 is a connection method using a ring, an attachable ring 11 is connected to the drone. The ring 11 may be rotatable in a circular ring shape. In this case, the connection part 120 includes a moving pin 121, a third motor 122, and a gear 123. The movable pin 121 is a pin inserted into the circle of the ring 11 and may have various lengths. A thread or groove may be formed on the outer surface of the movable pin 121. The movable pin 121 moves between spaced apart spaces of the body of the connection part 120.

The third motor 122 serves to move the moving pin 121. The third motor 122 can rotate in a forward or reverse direction, and changes the position of the moving pin 121. For example, when the third motor 122 rotates forward, the movable pin 121 is separated from the ring 11, and when it moves in the reverse direction, the movable pin 121 is movable inside the ring 11. Accordingly, the drone mission device 100 may be separated or combined from the drone according to the position of the moving pin 121.

The gear 123 is connected to the central axis of the third motor 122 and meshes with the moving pin 121. In this case, it is preferable that a thread is formed on the surface of the moving pin 121. The gear 123 may be replaced with various types of gears 123 according to the positions of the moving pins 121 and the third motor 122. The third motor 122 is driven and controlled by the control unit 140.

FIG. 5 is an exemplary view for explaining the implementation of the connection part in a switch magnet connection method in the drone detachable mission device using a magnet according to FIG. 2, and FIG. 6 is an exemplary view for explaining the operation of the switch magnet in FIG. 5. .

2, 5 and 6, the connection unit 120 includes a switch magnet 124 and a fourth motor 125. The switch magnet 124 includes a first magnet 124-1, a second magnet 124-2, a first housing 124-3, a second housing 124-4, and a disk 124-5. do. The first magnet 124-1 is a cylindrical magnet in which the N and S poles are formed by half and half. One side of the first magnet 124-1 magnetically contacts the connection plate 12 attached to the drone. The second magnet 124-2 is a cylindrical magnet in which the N and S poles are formed by half and half. A magnet groove (124-21) is formed on one side of the second magnet (124-2). The magnet groove (124-21) is a configuration for rotating the second magnet (124-2) by an external force. The first magnet 124-1 and the second magnet 124-2 are stacked on each other in the same manner as a millstone.

In this case, a shielding film capable of shielding a magnetic field may be attached to the drone 10 or the surface may be coated with a paint of a magnetic field shielding component. As another example, the connection plate 12 may be formed to be spaced apart from the drone 10 at regular intervals through a strap connected to the body of the drone 10. This is to prevent an error in the geomagnetic sensor of the drone 10 itself due to magnetic force generated when combined with the mission device 100.

The first housing 124-3 is formed of a ferromagnetic pole. The second housing 124-4 is formed of a ferromagnetic pole, and is combined with the first housing 124-3 to form a cylindrical shape. The first housing 124-3 and the second housing 124-4 are formed in a curved shape and are formed of a ferromagnetic material having a low magnetic resistance. A first magnet 124-1 and a second magnet 124-2 are accommodated in the first housing 124-3 and the second housing 124-4. In this case, the first magnet 124-1 is fixed in the first housing 124-3 and the second housing 124-4, and the second magnet 124-2 is formed to be rotatable. The strength of the magnetic field by the first magnet 124-1 and the second magnet 124-2 varies depending on the thickness of the first housing 124-3 and the second housing 124-4.

The disk 124-5 is formed in a disk shape, and a coupling rod 124-51 is formed on one side. The coupling rod (124-51) is coupled to the magnet groove (124-21) of the second magnet (124-2). This is to rotate the second magnet 124-2 when the disk 124-5 rotates. The coupling rods 124-51 of the disk 124-5 are not limited to those shown in FIG. 5 and may be variously modified. A central groove (124-52) is formed in the center of the disk (124-5). The central groove (124-52) is coupled to the central axis of the fourth motor (125).

The fourth motor 125 is connected by inserting the drive shaft into the central groove 124-52 of the disk 124-5. The fourth motor 125 rotates the disk 124-5 and the second magnet 124-2 while rotating in the forward and reverse direction. Since the disk 124-5 and the second magnet 124-2 are connected to each other, they interlock together. The fourth motor 125 may rotate the disk 124-5 and the second magnet 124-2 at various angles. This is to induce different magnetic coupling between the first magnet 124-1 and the second magnet 124-2. The driving of the fourth motor 125 is controlled by the controller 140.

6, (a) shows that the first magnet 124-1 and the second magnet 124-2 are stacked to have opposite polarities, and (b) is the first magnet 124-1 and the second magnet. It shows that the magnets 124-2 are stacked to have the same polarity. As shown in (a), when the first magnet 124-1 and the second magnet 124-2 are stacked with opposite polarities to each other, the magnetic force is applied only to the inside, so that the magnetic force is not applied to the outside. The magnetic force of the body is weakened and it is deviated. On the other hand, as shown in (b), when the first magnet 124-1 and the second magnet 124-2 are stacked with the same polarity, the magnetic force with the connection plate 12 increases and is fixed as the magnetic force increases to the outside.

On the other hand, when the connection part 120 is connected in the form of an electromagnet, an attractive force acts when attached to a drone, and a repulsive force acts when detaching from the drone. In this case, a connection plate 12 in the form of an iron plate may be formed on the drone. The connection unit 120 maintains the same state even when the power is turned off while changing the magnetism when power is supplied under the control of the controller 140. Therefore, power is supplied at the time of attachment to the drone and at the time of detachment, and the magnetism is reversed.

The communication unit 130 communicates with an external user terminal. The communication unit 130 can communicate with a remote user terminal through a long-distance network. The communication unit 130 receives a control signal from an external user terminal and outputs it to the control unit 140. For example, the communication unit 130 is capable of 3G, 4G, and 5G communication network methods or satellite communication. The communication unit 130 may transmit information on whether the functional unit 110 is normally separated to the user terminal. Since the communication unit 130 can communicate with the drone, it is also possible to transmit departure information from the drone to the drone in addition to the user terminal. In this case, the drone may transmit a warning signal to the user terminal when the functional unit 110 deviates before the target point.

The control unit 140 separates the functional unit 110 from the drone through a control signal from the user terminal. The control unit 140 drives the connection unit 120 to control the functional unit 110 to be attached to or detached from the drone. The control unit 140 may receive a control signal from an external user terminal to separate the connection unit 120 from the drone at a specific location. For example, when the connection part 120 is formed in the form of an electromagnet, the controller 140 may supply power to the electromagnet to make it magnetic so that the connection part 120 is attached to or detached from the drone. In this case, it is preferable that a connection plate 12 such as an iron plate or a magnetic chuck is formed on the drone.

In addition, the control unit 140 may separate only the functional unit 110 while the connection unit 120 is fixed to the drone. In this case, one side of the connection unit 120 may be connected to the drone, and the other side may be connected to the functional unit 110. In this case, the controller 140 may release the coupling of the functional unit 110 and the connection unit 120 while selectively maintaining the coupling of the drone and the connection unit 120 at the target point. Accordingly, the drone can reuse the connection unit 120 for various missions.

Meanwhile, a shielding film capable of shielding a magnetic field may be attached to the drone 10 or the surface may be coated with a paint of a magnetic field shielding component. As another example, the connection plate 12 may be formed to be spaced apart from the drone 10 at regular intervals through a strap connected to the body of the drone 10. This is to prevent an error in the geomagnetic sensor of the drone 10 itself due to magnetic force generated when combined with the mission device 100.

In addition, when the connection part 120 is formed in a ring-shaped connection method such as a hook or a robot arm, the controller 140 uses the third motor 122 to provide a moving pin 121 on the ring 11 formed on the drone. It can be controlled to be combined or separated. When the location of the drone reaches a specific location, the control unit 140 may control the connection unit 120 to separate the drone. When the drone is an aerial drone, the controller 140 may set a fall point according to the flight altitude of the drone. When the drone is an underwater drone, the controller 140 may set a separation point according to the movement of the tide.

In addition, when the connection unit 120 is formed by a connection method of an electromagnet, the control unit 140 may control the power supply of the connection unit 120 to be attached or detached to the drone. For example, the control unit 140 may supply power to the connection unit 120 and change the magnetic force to the opposite polarity by supplying power at a target point so as to be attached to the drone by magnetic force. Accordingly, it is possible to save energy by supplying power only when attached or detached, and securely fix the drone by magnetic force.

In addition, when the connector 120 is implemented as a switch magnet 124, the control unit 140 may rotate to adjust the magnetic coupling force using the fourth motor 125. For example, when the switch magnet 124 rotates the second magnet 124-2 from 0 degrees to a maximum of 180 degrees in the first direction, the magnetic force increases, and in the second direction opposite to the first direction, the magnetic force increases at 0 degrees. Rotating 180 degrees can reduce the magnetic force. The controller 140 rotates and fixes the second magnet 124-2 of the switch magnet 124 of the connection unit 120 in the first direction before the drone takes off. Thereafter, when the drone reaches the target point, the second magnet 124-2 of the switch magnet 124 is rotated in the second direction so that the functional unit 110 is separated.

7 is an exemplary diagram for explaining that a plurality of drones perform a mission through swarm flight through a movement detection unit in the drone mission device according to FIG. 2.

2 and 7, the drone detachable mission device 100 using a magnet according to an embodiment of the present invention may further include a movement detecting unit 150. The movement detection unit 150 is formed on one side of the function unit 110 and detects movement information of at least one of a position, altitude, speed, acceleration, and inclination. The movement detection unit 150 detects movement information of the function unit 110 itself to determine whether it has reached a target point. The movement detection unit 150 outputs movement information acquired in real time to the control unit 140.

For example, the movement detection unit 150 may be formed on one side of the functional unit 110 to detect a distance to the ground. The movement detection unit 150 transmits detection information to the control unit 140 at a preset time period. In this case, the control unit 140 may detect whether the function unit 110 has deviated from the drone through the movement detection unit 150.

In addition, the movement detection unit 150 may detect whether or not the function module 110-1 is discharged. The movement detection unit 150 may also detect the weight inside the functional unit 110. When the function module 110-1 is discharged from the body of the function unit 110, the movement detection unit 150 detects it and outputs it to the control unit 140. In this case, the control unit 140 may control even the weight of the function module 110-1.

In this case, the controller 140 transmits movement information to the user terminal when it is separated from the drone. This is to determine whether the functional unit 110 has reached the target point. In addition, the controller 140 may acquire movement information while the drone is moving and transmit it to the user terminal. This is to determine whether the functional unit 110 has deviated before the drone reaches the target point. In addition, the control unit 140 may obtain the movement information of the drone from the user terminal and compare it with the movement information of the function unit 110 to transmit a warning signal to the user terminal when it exceeds a preset error range.

In addition, as shown in FIG. 7, when there is no additional movement within a predetermined time after the functional unit 110 falls to the target point, the mission device 100 of the other drone 10 may be dropped to the target point. Here, the additional movement refers to information such as pressure and inclination about whether a drowning person or the like grips the functional unit 110 after falling. If there is no additional movement for the mission device 100, it is determined that the mission has failed, and an additional rescue signal may be transmitted to drop the mission device 100 of the other drone 10. In this case, the controller 140 may transmit a falling call to another drone 10 in swarm flight through the communication unit 130.

In addition, the plurality of drones 10 may drop the mission device 100 on which different functional modules 110-1 are mounted. Accordingly, it is possible to increase the possibility of rescue for a victim or a drowned person by dropping the additional mission device 100 at a target point while the plurality of drones 10 are flying in a swarm. In this case, the plurality of drones 10 may use fixed-wing or rotary-wing type aerial drones or underwater drones.

Meanwhile, a shielding film capable of shielding a magnetic field may be attached to the drone 10 or the surface may be coated with a paint of a magnetic field shielding component. As another example, the connection plate 12 may be formed to be spaced apart from the drone 10 at regular intervals through the strap 13 connected to the body of the drone 10. This is to prevent an error in the geomagnetic sensor of the drone 10 itself due to magnetic force generated when combined with the mission device 100.

Referring back to FIG. 2, the drone detachable mission device 100 using a magnet according to an embodiment of the present invention may further include an image acquisition unit 160. The image acquisition unit 160 is formed on one side of the function unit 110 to acquire an image. The image acquisition unit 160 photographs the ground when the tip of the functional unit 110 faces the ground. The state of the ground can be monitored by the image acquisition unit 160. The image information acquired from the image acquisition unit 160 may be transmitted to an external server at a preset time period.

In this case, the controller 140 may drive the image acquisition unit 160 when the functional unit 110 switches to vertical flight during horizontal flight. In other words, the function unit 110 is attached to the drone so that it does not operate during flight and then separates from the drone to obtain an image. Accordingly, it is possible to obtain an image near the target point while reducing power consumption.

In addition, the controller 140 may control to acquire an image of a movement path of the function unit 110 and a discharge location of the function module 110-1 through the image acquisition unit 160. When delivery is completed depending on whether or not the function module 110-1 is delivered, it is also possible to provide an image of a discharge location provided through the image acquisition unit 160 to the user.

Meanwhile, the drone detachable mission device 100 using a magnet according to an embodiment of the present invention may further include a flying unit 170. The flight unit 170 may move the functional unit 110 by the power of the mission device 100 itself. The flying unit 170 is formed on one side of the function unit 110 with a blade in the form of a fixed wing or a rotary wing. The flight unit 170 is a means for firstly moving the functional unit 110 to the target point by the drone, and then moving the functional unit 110 closer to the target point in the second order. In addition, when the battery of the drone is exhausted, the flight unit 170 may be separated from the drone before the target point and can fly by itself.

In this case, the controller 140 may control the driving of the flight unit 170 from an external user terminal. The control unit 140 determines whether to drive the flight unit 170 when the functional unit 110 is separated from the drone. The controller 140 drives the flight unit 170 when there is an auxiliary flight signal from the flight unit 170 from the user terminal. Even when there is no auxiliary flight signal from the user terminal, the control unit 140 may analyze the movement information of the function unit 110 and automatically control the flight unit 170 when the movement path deviates from the target point.

In addition, the controller 140 compares the movement information of the drone with the movement information of the function unit 110 to determine whether the function unit 110 has deviated from the drone before the target point. When the function unit 110 deviates before the target point, the control unit 140 may control the flight unit 170 to move to the coordinates of the target point. In addition, there is an effect of reducing the impact to prevent damage to items such as emergency medicines to the functional unit 110.

Meanwhile, the drone detachable mission device 100 using a magnet according to an embodiment of the present invention may further include an alarm unit 180. The alarm unit 180 may be implemented in the form of an LED, a speaker, a display, etc., but is not limited thereto. The alarm unit 180 serves to enable the victim or rescuer to determine the location. The alarm unit 180 may be implemented in the form of various sensors such as a GPS sensor or a smoke bomb. In this case, the victim or the rescuer can notify the outside of his/her location by manipulating the alarm unit 180 while holding the mission device 100.

In the above, the present invention has been described centering on the preferred embodiments described with reference to the drawings, but is not limited thereto. Accordingly, the present invention should be interpreted by the description of the claims intended to cover obvious modifications that can be derived from the described embodiments.
