BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drone system,

The present invention relates to a drones system, and more particularly to a drones system that is controllable over the Internet.

Unmanned aerial vehicles (UAVs), which can be remotely operated without people getting on board, are represented by drones and are now widely used in civilian markets as well as military.

Drones can be used to manage and monitor specific areas where access is difficult. Specifically, the drone can move freely and quickly, and can carry out remote monitoring of a specific area through the mounted camera or sensor. That is, the drones can be used for public purposes such as victim search, wildfire monitoring, traffic violation control, hunting areas and border area surveillance.

The drones move to the air, so they are very mobile. In other words, even in severe traffic congestion and rough roads, the drones can move quickly through the air.

Korean Patent Laid-Open Publication No. 10-2016-0048737 discloses a " life-saving structure and environment monitoring drones having a simple operation function ", and a drones capable of quickly and safely constructing a dewatering device using a remote and simple adjustment function Lt; / RTI >

1 is a block diagram of a conventional joystick for dron control.

Referring to FIG. 1, the user adjusts the direction of movement of the dron using the left adjustment stick 11 and the right adjustment stick 12.

In general, when the left adjustable stick 11 is moved back and forth (throttle), the drone moves up and down in the vertical direction (ground-air).

In addition, when the left adjustable stick 11 is moved left and right (yaw), the drone rotates clockwise or counterclockwise.

Further, when the right adjustable stick 12 is moved back and forth (pitch, pitch), the drone moves forward and backward in the horizontal direction.

Further, when the right adjustable stick 12 is moved left and right (roll, roll), the drone moves leftward and rightward in the horizontal direction.

Thus, although the conventional drones control movement using a joystick, it is difficult to precisely control the operation of the dron with the joystick alone. Also, there is a disadvantage that only one designated dron can be adjusted with the joystick alone.

Each sensing sensor may be constituted by a switching element that distinguishes whether the finger is in the open state or the bent state by turning on (TURN ON) or turning OFF (TURN OFF).

For example, when the user bends the first finger 201, the power source is turned on (TURN ON). At this time, in order to prevent malfunction of the turn-on (TURN ON), the power is turned on when the first finger 201 is bent a predetermined number of times, and when the power is turned off TURN OFF).

On the other hand, the turn-on / turn-off (TURN OFF) of the second finger 202,

Turn on / turn off (TURN OFF) of the third finger 203,

Turn on / turn off (TURN OFF) of the fourth finger 204,

When the number of turns of the fifth finger 205 is TURN ON / TURN OFF, it is possible to indicate all 16 states, so that the drones move corresponding to the sixteen states You can tell.

That is, it is possible to indicate the operation of the drone (throttle, yaw, pitch, roll) in correspondence with the sixteen states of the fingers.

- Second Embodiment of Wearable Glove (200)

The wearable glove 200 is configured to be worn by a user in one hand or worn by both hands, and is configured to be able to sense movement of each finger and three-dimensional movement of a hand wearing gloves.

At this time, the wearable glove 200 includes a plurality of motion detection sensors 201, 202, 203, 204, 205, a posture orientation sensor 210, and an operation control unit 220.

Each sensing sensor may be constituted by a switching element that distinguishes whether the finger is in the open state or the bent state by turning on (TURN ON) or turning OFF (TURN OFF).

For example, when the user bends the first finger 201, the power source is turned on (TURN ON). At this time, in order to prevent malfunction of the turn-on (TURN ON), the power is turned on when the first finger 201 is bent a predetermined number of times, and when the power is turned off TURN OFF).

Also, the posture orientation sensor 210 of the wearable glove 200 senses the three-dimensional movement.

That is, the orientation orientation sensor 210 is the most popular among the sensors capable of sensing operations in a three-dimensional space, and may be referred to as a 9-axis sensor. The 9 axis is referred to as a 9 axis sensor since the values of 9 axes are measured as three axes of acceleration, 3 axes of inertia and 3 axes of geomagnetism, and a temperature sensor may be additionally provided for correcting the temperature value.

Therefore, the orientation sensor 210 can sense the three-dimensional motion of the wearer wearing the wearable glove 200.

At this time, the TURN ON / TURN OFF of the second finger 202, the TURN ON / TURN OFF of the third finger 203, the fourth finger 204, Turn ON / turn off of the fifth finger 205 and turn on / turn off of the fifth finger 205, respectively, and the turn-

(Throttle, yaw, pitch, roll) of the drones by combining the three-dimensional motions of the wearable gloves 200 sensed by the orientation-orientation sensor 210, respectively.

Third Embodiment of Wearable Glove 200 -

The wearable glove 200 is configured to be worn by a user in one hand or worn by both hands, and is configured to be able to sense movement of each finger and three-dimensional movement of a hand wearing gloves.

At this time, the wearable glove 200 includes a plurality of motion detection sensors 201, 202, 203, 204, 205, a posture orientation sensor 210, and an operation control unit 220.

The plurality of motion detection sensors 201, 202, 203, 204, and 205 are disposed inside the gloves in which the respective fingers are located so as to detect independent movement of the respective fingers. For reference, each sensing sensor may be attached to the outside of the glove, and may be formed to surround the surface of each finger three-dimensionally.

That is, each sensing sensor is configured to have an elastic force so as to be able to grasp the degree of bending of a finger to be handled. The sensing sensor may be composed of a device whose resistance varies according to the degree of bending of the finger, and it is preferable to use a device whose resistance changes in accordance with two-dimensional movement.

Therefore, the detection sensor is configured to detect whether the finger is in the opened state, the bent state, and the bent state.

For example, when the user bends the first finger 201, the power source is turned on (TURN ON). At this time, in order to prevent malfunction of the turn-on (TURN ON), the power is turned on when the first finger 201 is bent a predetermined number of times, and when the power is turned off TURN OFF).

In addition, in accordance with the bending operation of the second finger 202, a throttle operation, that is, a dron is set to move up and down in the vertical direction (ground-air).

Also, the yaw operation, that is, the dron is set to rotate clockwise or counterclockwise, corresponding to the bending operation of the third finger 203.

In addition, the pitch operation, that is, the dron is set to move forward and backward in the horizontal direction corresponding to the bending operation of the fourth finger 204.

In addition, the roll operation, that is, the drones is set to move leftward and rightward in the horizontal direction corresponding to the bending operation of the fifth finger 205.

At this time, the setting position of the operation corresponding to each finger (throttle, yaw, pitch, roll) may be changed according to the detailed setting of the user.

For reference, the wearer can wear the wearable glove 200 at the same time on the left hand and the right hand, respectively. Thus, when the user wears wearable gloves on both hands,

The upward movement of the throttle advances in accordance with the bending operation of the second finger 202 of the right hand and the downward movement of the throttle can proceed in response to the bending operation of the second finger of the left hand have.

In accordance with the bending operation of the third finger 203 of the right hand, the clockwise rotation of the yaw progresses, and in response to the bending operation of the third finger of the left hand, A clockwise rotation operation can proceed.

Further, the horizontal advancing operation of the pitch is progressed corresponding to the bending operation of the fourth finger 204 of the right hand, and the horizontal backward movement of the pitch corresponding to the bending operation of the fourth finger of the left hand The operation can proceed.

In addition, the horizontal right movement of the roll movement is progressed in response to the bending operation of the fifth finger 205 of the right hand, and the roll operation is performed corresponding to the bending operation of the fifth finger of the left hand. The horizontal leftward movement operation of the left-hand side can proceed.

On the other hand, the orientation orientation sensor 210 of the wearable glove 200 senses a three-dimensional movement.

That is, the orientation orientation sensor 210 is the most popular among the sensors capable of sensing operations in a three-dimensional space, and may be referred to as a 9-axis sensor. The 9 axis is referred to as a 9 axis sensor since the values of 9 axes are measured as three axes of acceleration, 3 axes of inertia and 3 axes of geomagnetism, and a temperature sensor may be additionally provided for correcting the temperature value.

Therefore, the orientation-orientation sensor 210 includes an acceleration sensor, an inertial sensor (gyro sensor), and a geomagnetic sensor.

Acceleration sensors represent information including gravitational acceleration (g = 9.8 ㎨). In the acceleration sensor, three axes sense acceleration in the x-, y-, and z-axes when the sensor moves in three dimensions.

In addition, the inertial sensor (gyro sensor) measures the angular velocity, and the angular velocity means the angle of rotation per hour.

Also, the geomagnetic sensor is used to measure the absolute direction using the acceleration.

Therefore, the posture orientation sensor 210 senses the three-dimensional motion of the hand wearing the wearable glove 200 and then detects throttle, yaw, pitch (pitch) of the dragon 100, ) And roll operation.

For example, when the user turns the hand of the wearable glove 200 toward the ground and the back of the hand moves toward the air, when the first finger 201 is bent a predetermined number of times, the power turns on (TURN ON) Sets the dimension position to a default value, and the drone 100 proceeds with the hovering operation at the current position.

At this time, when the user pushes his / her hand horizontally forward or backward, the drone 100 proceeds to pitch operation corresponding to the operation.

In addition, when the user moves the hand horizontally to the left and right, the drone 100 advances the roll operation in response to the operation.

When the user raises and lowers the hand in the vertical direction, the drone 100 proceeds to the throttle operation in accordance with the operation.

Further, when the user rotates the hand so that the finger faces the right or left side, the drone 100 advances the yaw operation corresponding to the operation.

In addition, when the user rotates the palm rapidly toward the air, the operation of the drone 100 is reversed in response to the operation.

In addition, the speed of the throttle, yaw, pitch, and roll is adjusted in proportion to the speed at which the user's hand is moved.

That is, the moving direction of the drones 100 is adjusted in accordance with the three-dimensional motion detected by the orientation-orientation sensor 210.

Basically, only one of the plurality of motion detection sensors 201, 202, 203, 204, and 205 and the orientation / orientation sensor 210 is set to adjust the moving direction of the drones 100.

At this time, the plurality of motion detection sensors 201, 202, 203, 204 and 205 and the orientation / orientation sensor 210 can control the movement direction of the drones 100 according to the user's detailed setting.

The user sets the motion weight (0 to 100%) of the motion detection sensors 201, 202, 203, 204 and 205 and the motion weight (0 to 100%) of the posture orientation sensor 210, Can be set to suit the physical condition of the user. For reference, when the detection sensor and the orientation sensor 210 simultaneously instruct opposite operations, only one sensor having a high weight is operated.

Meanwhile, when one dron is controlled, the wearable glove 200 worn by the user's right hand outputs a first control signal corresponding to the plurality of motion detection sensors 201, 202, 203, 204, 205, and wearable gloves 200 can output a second control signal corresponding to the orientation-orientation sensor 210, so that the drones 100 can be dynamically controlled. That is, the right hand can be configured to control the operation of the drones 100 by the movement of the fingers, and the left hand can simultaneously control the operation of the drones 100 by the three-dimensional movement of the hands.

The operation control unit 220 converts the sensing signals (the first control signal and the second control signal) of the plurality of motion sensors 201, 202, 203, 204 and 205 and the orientation sensor 210 into a drones posture control signal, To the drone (100). Here, the wireless communication method may be a local wireless network method such as a WIFI method, and a broadband wireless network method such as 2G, 3G, or LTE method.

That is, the wearable glove 200 and the drones 100 exchange data with each other using a wireless communication method. In this case, the first control signal corresponding to the movement of each finger and the second control signal corresponding to the three- Is transmitted to the drone (100) through the wireless communication system.

FIG. 3 is a configuration diagram of a dron system 2 according to another embodiment of the present invention, FIG. 3a is a configuration diagram of a dron system 3 according to another embodiment of the present invention, and FIG. Fig.

The drone system 1 according to the present embodiment includes only a simple structure for clearly explaining the technical ideas to be proposed.

3, 3A and 4, the dron system 2 according to another embodiment includes a plurality of drones 101, 102, and 103, a wearable glove 200, and a portable terminal 300.

In addition, the dron system 3 according to another embodiment includes a plurality of drones 101, 102, and 103, a wearable glove 200, and a touch screen 230.

The detailed configuration and main operation of the dron system 2 configured as described above will be described below.

As described in detail with reference to FIG. 2, the wearable glove 200 senses the movement of the finger and its own three-dimensional movement.

The plurality of drills (101, 102, 103) are adjusted in the moving direction corresponding to the movement of each finger sensed by the wearable glove (200) and the three dimensional movement of the wearable glove.

The portable terminal 300 monitors the positions of the plurality of drones 101, 102 and 103 in real time and selects and controls one of the drones using a touch screen.

That is, the wearable glove 200 adjusts the movement direction of at least one or more drones selected by the touch screen of the portable terminal 300.

Here, the portable terminal 300 is collectively referred to as a portable terminal such as a mobile phone, a smart phone, and a smart pad, and is assumed to be a portable terminal configured as a smart phone in the present embodiment.

The positions of the plurality of drones 101, 102 and 103 are simultaneously displayed on the touch screen of the portable terminal 300. Accordingly, when the user touches the touch screen of the portable terminal 300 and selects one of the plurality of drones 101, 102, and 103, the selected dron operates in accordance with the movement of the wearable glove 200.

The portable terminal 300 and the wearable glove 200 must perform user authentication and synchronization before controlling the drones and the portable terminal 300 and the wearable glove 200 must perform local wireless communication such as WiFi . Therefore, when a dron is selected through the touch screen of the portable terminal 300, the dron selection signal is transmitted to the corresponding dron via the wearable glove 200.

At this time, according to the detailed setting of the user, the dron selection signal of the portable terminal 300 can be directly transmitted to the corresponding drones without passing through the wearable gloves 200. At this time, it is preferable that the portable terminal 300 and the drone are connected by a non-local wireless communication method or a broadband wireless communication method.

The plurality of drills (101, 102, 103) operate to transfer signals transmitted from the portable terminal (300) and the wearable glove (200) to each other via a neighboring drone.

That is, when the wearable glove 200 controls the third drones 103, there is no problem in the control when the third drones 103 are positioned within the effective distance at which the control signals can be effectively transmitted. However, when the distance between the third drones 103 and the wearable gloves 200 exceeds the effective distance, there arises a problem that the drones 100 can not be controlled.

The drones 2 according to the embodiment of the present invention are configured to transmit a plurality of drones 101, 102 and 103 via signals to each other so that after the first drones 101 at the closest distance receive the control signals The second drones 102 may transmit the control signals to the third drones 103 that are farthest from the first drones 102 and 103, respectively.

As a result, even if the third drone 103 exceeds the effective distance, the control signal can be received by the other drone, so that the effective distance that the portable terminal 300 can control substantially increases.

The operation of controlling the plurality of drones 101, 102, and 103 using the touch screen of the portable terminal 300 and the wearable glove 200 will be described in more detail as follows.

It is assumed that the first drones 101, the second drones 102, and the third drones 103 are hovering-maintaining the current position in the air while maintaining a predetermined distance.

First, when the user selects the first drones 101 using the touch screen of the portable terminal 300 and selects the second drones 102 while controlling the operation of the first drones 101, The controller 101 performs an operation according to the last control signal by a predetermined basic distance or a basic angle, and then performs a hovering operation.

For example, when the last control signal of the first drones 101 is a horizontal advance movement operation and the basic distance is 3 m, the first drones 101 advances 3 m horizontally, and proceeds to hover at that position.

Next, when selecting the "alignment mode" in the course of controlling the operation of the second drones 102 selected by the user, the first drones 101 and the third drones 103, respectively, 2 drones 102 to the maximum effective distance.

At this time, when the user moves the second drones 102 while maintaining the alignment mode, the first drones 101 and the third drones 103 are also maintained at the same distance from the second drones 102 Move. That is, the first dron 101 and the third dron 103 move simultaneously as the user controls the second dron 102.

For reference, in the alignment mode, when the drones of one of the plurality of drones 101, 102, and 103 approach a dangerous distance at which they can collide with the ground, the sorting operation of the corresponding drones is released and the hovering operation proceeds at that position. In addition, the alignment mode is configured to be selectable in the portable terminal 300 or the wearable glove 200.

On the other hand, in the touch screen of the portable terminal 300, an image at the viewpoint of each dron, that is, the first person's view of the selected dron can be displayed so that the user can adjust the dron with reference to the view of the selected dron.

As shown in the touch screen of the portable terminal 300 of FIG. 3, when communicating between the plurality of drones 101, 102 and 103 via the control signal, the communication state between the drones can be displayed corresponding to the line thickness .

That is, the communication status indicating line between the first and second drums 101 and D1 and the second drones 102 and D2 is thicker than the communication status indicating line between the second and third drums 102 and D2 and 103 and D3 The larger the communication status indication line is, the more the communication status is smooth, and the effective distance that can be adjusted through the communication status indication line can be indirectly confirmed.

3A, the dron system 3 according to another embodiment includes a plurality of drones 101, 102, and 103, a wearable glove 200, and a touch screen 230.

The dron system 3 according to another embodiment has a touch screen 230 attached to the wearable glove 200. When a user touches the touch screen 230 to select any one of the plurality of drones 101, The selected drones are operated in accordance with the movement of the wearable glove 200.

The wearable glove 200 of the dron system 3 configured as described above detects movement of the finger and its own three-dimensional movement, as described in detail with reference to FIG. 3, when the user touches the touch screen of the portable terminal and selects one of the plurality of drones 101, 102, and 103, the selected dron is operated in accordance with the movement of the wearable glove 200 .

The dron system 3 shown in FIG. 3A has a structure in which the touch screen of the portable terminal 300 of the dron system 2 shown in FIG. 3 is attached to the wearable glove 200 and the wearable glove 200 and the touch screen 230, An example of this integrated type is shown.

The touch screen 230 attached to the wearable glove 200 is preferably a flexible material display and can be attached to the back of the wearable glove 200 or the palm of the wearable glove 200.

Since the operation of the touch screen 230 is the same as that of the touch screen of the portable terminal 300, a duplicate description will be omitted.

The dron system according to the embodiment of the present invention can adjust the moving direction of the dron using the wearable gloves so that the moving direction of the dron can be more precisely controlled.

In addition, since the wearable glove can adjust the moving direction of at least one of the plurality of drones selected by the touch screen, the movement directions of the plurality of drones can be controlled by using one wearable glove.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
