FIG. 1 is a schematic diagram of a system for transmitting and receiving a distress signal according to an embodiment of the present invention.
The system for transmitting and receiving a distress signal according to an embodiment of the present invention may include a kit 10 and a control server 20. The kit 10 may transmit a distress signal to the control server 20, and the control server 20 may receive the distress signal and acquire a location of the kit 10 and a distress type included in the distress signal. Through this, personnel who control the control server 20 can check the distress signal and take appropriate measures.
FIGS. 2 and 3 are perspective views illustrating the kit 10 in an unfolded state according to an embodiment of the present invention.
The kit 10 may include a base unit 100 and a plurality of arm units 200 connected to the base unit 100.
The base unit 100 may include a base plate 110, a case 120 and a long-distance communication module 130.
A plurality of arm units 200 may be disposed to be spaced apart from each other along the circumferential direction around the base plate 110, wherein an end of each of the plurality of arm units 200 facing the base plate 110 is connected to the base plate 110. In one embodiment, the base plate 110 may be formed in a plate shape having the same number of lateral surfaces as the number of the plurality of arm units 200. For instance, when the number of the plurality of arm units 200 is six (6), the base plate 110 may be formed in a hexagonal plate shape, but is not limited thereto.
Each of the plurality of arm units 200 and the base plate 110 may be connected by a first hinge 231. In one embodiment, a plurality of first hinges 231 may be used to connect one arm unit 200 and the base plate 110. In one embodiment, the first hinge 231 consists of two members connected to each other to be folded or unfolded. As a structure in which two members can be folded or unfolded relative to each other, different known structures may be used. One of the two members constituting the first hinge 231 is coupled to the arm unit 200 while the other is coupled to the base plate 110. Through this, any one point included in the arm unit 200 may be rotated in a direction in which the first hinge 231 is folded or unfolded while centering around the folded portion of the first hinge 231. In one embodiment, the first hinge 231 may be folded or unfolded such that the two members form an angle between 0° and 180° to each other.
As the first hinge 231 is folded, the arm unit 200 may be rotated based on the folded portion of the first hinge 231. In one embodiment, the arm unit 200 may rotate from a state parallel to the upper surface of the base plate 110 to a state perpendicular to the upper surface of the base plate 110 with reference to the folded portion of the first hinge 231, but is not limited thereto. In one embodiment, in a state in which the first hinge 231 is fully unfolded, the base plate 110 and the arm unit 200 may be disposed in parallel with each other. In one embodiment, in a state in which the first hinge 231 is maximally folded, the base plate 110 and the arm portion 200 may be disposed perpendicular to each other, but are not limited thereto. The first hinge 231 may be folded until the arm unit 200 contacts the outer surface of the case 120 and is then supported. In one embodiment, the arm unit 200 may rotate counter-clockwise until the angle between the base plate 110 and the arm unit 200 reaches a preset maximum angle while the base plate 110 is fixed. In one embodiment, the arm unit 200 may rotate clockwise until the angle between the base plate 110 and the arm unit 200 becomes a preset minimum angle while base plate 110 is fixed. In one embodiment, the preset maximum angle is 180°, while the preset minimum angle may be an angle formed by the arm unit 200 and the base plate 110 at a time when the arm unit 200 and the outer surface of the case 120 are in contact with each other and then supported.
As the first hinge 231 is folded, the arm unit 200 may rotate clockwise or counter-clockwise based on the folded portion of the first hinge 231. That is, the arm unit 200 may rotate clockwise or counter-clockwise while the base plate 110 is fixed.
The case 120 is coupled to the upper surface of the base plate 110 and forms an internal space open upward along with the upper surface of the base plate 110. In the inner space of the case 120, a short-range communication module 140, a processor 150, a battery 160, and a GPS module 170 may be disposed.
The long-distance communication module 130 is coupled to the upper surface of the base plate 110 and extends upward in a columnar shape. A communication signal may be amplified through the long-distance communication module 130.
The arm unit 200 may include a first arm 210 and a second arm 220 connected to each other.
The first arm 210 is connected to the base plate 110 by a first hinge 231, while the second arm 220 is connected to the first arm 220 by a second hinge 232. In one embodiment, the second hinge 232 may consist of two members connected to each other to be folded or unfolded. As a structure in which two members can be bent or stretched (that is, folded or unfolded) relative to each other, a variety of known structures may be used. One of the two members constituting the second hinge 231 is coupled to the first arm 210 and the other is coupled to the second arm 220. Hence, any one point included in the second arm 220 may be rotated in a direction in which the second hinge 232 is folded or unfolded while centering around the folded portion of the second hinge 232. In one embodiment, the second hinge 232 may be folded or unfolded such that the two members form an angle between 0° and 180° to each other.
In one embodiment, a plurality of second hinges 232 may be used to connect the first arm 210 and the second arm 220.
As the second hinge 232 is folded, the second arm 220 may rotate based on the folded portion of the second hinge 232. In one embodiment, the second arm 220 may rotate from a state parallel to the upper surface of the first arm 210 to a state perpendicular to the upper surface of the first arm 210, with reference to the folded portion of the second hinge 232, but is not limited thereto. In one embodiment, in a state in which the second hinge 232 is fully unfolded, the first arm 210 and the second arm 220 may be disposed in parallel with each other. In one embodiment, as the second hinge 232 is folded, the first arm 210 and the second arm 220 may be disposed perpendicular to each other. Further, in a state in which the second hinge 232 is maximally folded, one side of the second arm 220 may come into contact with the first light emitting module 213 disposed on the upper surface of the first arm 210.
As the second hinge 232 is folded, the second arm 220 may rotate clockwise or counter-clockwise based on the folded portion of the second hinge 232. That is, the second arm 220 may rotate clockwise or counter-clockwise while the first arm 210 is fixed. In one embodiment, the second arm 220 may rotate counter-clockwise until the angle between the first arm 210 and the second arm 220 reaches a preset maximum angle while the first arm 210 is fixed. In one embodiment, the second arm 220 may rotate clockwise until the angle formed by the first arm 210 and the second arm 220 reaches a preset minimum angle while the first arm 210 is fixed. In one embodiment, the preset maximum angle may be 180° and the preset minimum angle may be 0°.
With both the first hinge 231 and the second hinge 232 fully extended, the first arm 210 and the second arm 220 may extend in the radial direction of the base plate 110.
In a state in which all of the first hinges 231 are fully unfolded, the first arms 210 connected to the base plate 110 may be positioned parallel to the base plate 110. Therefore, the kit 10 can be stably supported by the lower surface of the base plate 110 and the lower surfaces of the first arms 210.
Further, in a state in which all of the second hinges 232 are half-opened, the second arms 220 extend upward.
As shown in FIGS. 2 and 3, the user can operate the kit 10 to lead to a first state such that the first arms 210 are disposed parallel to the base plate 110 while the second arms 220 are arranged to extend upward at a predetermined angle with the first arms 210. Further, in the first state, the kit 10 may send a distress signal.
The first arm 210 may include a first arm plate 211, a first solar panel 212 and a first light emitting module 213.
The first arm plate 211 is directly connected to the base plate 110 through the first hinge 231. In one embodiment, the first arm plate 211 may be formed in a rectangular plate shape, but is not limited thereto.

The plurality of first through holes 211a may be spaced apart from one another along the extending direction of the first arm plate 211. The first through hole 211a may be formed in a rectangular shape, but is not limited thereto, and may be formed in diverse shapes. As the plurality of first through holes 211a are formed, the overall weight of the kit 10 is reduced so that the portability of the kit 10 can be improved.
In one embodiment, when a direction in which the first arm plate 211 extends is referred to as a first direction (or referred to as a length direction), and a direction crossing the extended direction is defined as a second direction (or referred to as a width direction), the first through hole 211a may be disposed at the center of the first arm plate 211 in the second direction.

The second through hole 221a may be formed in a rectangular shape, but is not limited thereto, and may be formed in diverse shapes. As the plurality of second through holes 221a are formed, the overall weight of the kit 10 is reduced so that the portability of the kit 10 can be improved.
In one embodiment, when a direction in which the second arm plate 221 extends is referred to as a first direction (or referred to as a length direction), and a direction crossing the extended direction may be defined as a second direction (or referred to as a width direction), the second through hole 221a may be disposed at the center of the second arm plate 221 in the second direction.

FIG. 8 is a flowchart illustrating a process of generating a distress signal by the kit 10 according to FIG. 1.
The distress signal generator 103 transmits the distress signal including the distress type, the user's identification number and the user's location determined by the GPS module to the control server 20 through the long-distance communication module 130 (S110).
The user's identification number may be stored in the database 180 of the kit 10.
The distress signal generator 103 may receive a distress type through an input interface device (not shown) of the kit 10. In one embodiment, wounds, emergency injury, isolation, etc. may be set as the distress type, and the user may input a selection signal corresponding to any one of wounds, emergency injury, and isolation through an input interface device (Midos).
In one embodiment, the distress signal generator 103 may transmit a distress signal including the user's identification number and the user's location determined by the GPS module to the control server 20 through the long-distance communication module 130. In one embodiment, when the kit 10 is operated in the second state, the distress signal generator 103 may transmit the distress signal to the control server 20 through the long-distance communication module 130.
The control server 20 may identify the user's identity using the user's identification number and determine the user's location. Further, appropriate rescue measures corresponding to the type of distress may be performed for the user. For example, when the distress type is an emergency injury, a procedure may be performed to secure the user's identity as quickly as possible and transport the user to a medical institution.
The distress signal generator 103 may send a distress signal including the type of distress, the identification number of the user, and the location of the user determined by the GPS module 170 through the short-range communication module (S120).
The user's identification number may be stored in the database 180 of the kit 10.
The distress signal generator 103 may receive a distress type through an input interface device (not shown) of the kit 10. In one embodiment, wounds, emergency injury, isolation, etc. may be set as the distress type, and the user may input a selection signal corresponding to any one of wounds, emergency injury, and isolation through an input interface device (Midos).
In one embodiment, the distress signal generator 103 may send a distress signal including the user's identification number and the user's location determined by the GPS module through the short-range communication module 140. Hence, the distress signal can be transmitted to another user's kit 10 located in the communication range of the short-range communication module. That is, even if transmission of the distress signal through the long-distance communication module 130 fails, when another user is located within the communication range of the short-distance communication module 140, the distress signal can be transmitted to the kit 10 of another user.
In one embodiment, when the kit 10 is operated in the second state, the distress signal generator 103 may send a distress signal through the short-range communication module 140.
The light emitting module controller 102 may control the first light emitting module 213 and the second light emitting module 223 to emit light in a pattern corresponding to the distress type (S130).
In the database 180 of the kit 10, each of a plurality of preset light emission patterns and each of a plurality of distress types are pre-matched and stored. The light emitting module controller 102 selects a light emission pattern corresponding to the distress type received from the database 180, and controls the first light emitting module 213 and the second light emitting module 223 to emit light according to the selected light emission pattern.
FIG. 9 is a flowchart illustrating a process that generates a distress signal by the kit 10 according to FIG. 1.
When a distress signal is received from another user's kit 10, the distress signal generator 103 in the kit 10 may send a rescue signal.
First, when the distress signal is received (S210), the distress signal generator 103 determines the direction and distance using a first location of a person in need of rescue included in the distress signal and a second location of the user determined by the GPS module 170 (S220).
For example, if a second location is 600 m northwest apart from a first location, southeast is determined as the direction and 600 m is determined as the distance. The direction is determined from the second position toward the first position.
In one embodiment, each of the plurality of preset directions may correspond to each of the arm units 200. When the number of arm units 200 is six, orientations divided into six (6) directions may be used, and a direction closest to an angle formed by the second position and the first position may be selected. For example, when it is assumed that north is 90°, 0°, 60°, 120°, 180°, 240° and 300° may be determined as directions corresponding to the six arm units 200. When the angle formed by the second position and the first position is 190° , a direction corresponding to 180° may be selected. A direction indicator may be formed on at least two of the arm units 200, and an azimuth meter (not shown) may be included in the kit 10. Hence, the user can arrange the kit 10 such that the arm units 200, on which the direction indicators are formed among all of the arm units 200, correspond to the azimuth meter.
The light emitting module controller 102 controls the first light emitting module 213 and the second light emitting module 223 of the arm unit 200 corresponding to the direction to emit light in a pattern corresponding to the distress type and distance included in the distress signal (S230).
The light emitting module controller 102 selects the arm unit 200 corresponding to the direction among all of the arm units 200.
In the database 180 of the kit 10, a plurality of preset light emission patterns and a plurality of distress types, respectively, may be pre-matched and stored. The light emitting module controller 102 selects a light emission pattern corresponding to the type of distress received from the database 180, and then controls the first light emitting module 213 and the second light emitting module 223 of the arm unit 200 corresponding to the direction to emit light according to the selected light emission pattern.
The first light emitting module 213 and the second light emitting module 223 may include a plurality of LED modules, and the light emitting module controller 102 may control the LED modules corresponding to the distance to emit light in a light emission pattern corresponding to the distress type.
The plurality of distance ranges and the number of LED modules are matched, respectively, and stored in the database 180 of the kit 10 in advance, and the light emitting module controller 102 may select the number of LED modules matching with the distance, and then control the selected number of LED modules to emit light in a light emission pattern corresponding to the distress type.
In one embodiment, the light emitting module controller 102 may select the number of LED modules matching with the distance in the order of proximity to the base plate 110, and then control the selected LED modules to emit light in a light emission pattern corresponding to the distress type.
Hence, the user receiving the distress signal (or referred to as “rescuer”) can grasp a distress type of a person in need of rescue (“distressed person”), a direction to be moved to reach the distressed person, and a distance to reach the distressed person.
The light emitting module controller 102 may send a rescue signal including an identification number included in the distress signal and a second location through the short-range communication module (S250).
FIG. 10 is a flowchart illustrating a process of receiving a rescue signal by the kit 10 according to FIG. 1.
When the rescue signal is received from another user's kit 10 (S310), the distress signal generator 103 determines whether the identification number included in the rescue signal is the same as the identification number of the distressed person (S320).
If the identification numbers are the same, the distress signal generator 103 determines the direction and distance using the second location of the rescuer in the rescue signal and the first location of the distressed person (S320).
For example, if the second location is 600 m northwest apart from the first location, northwest is determined as the direction and 600 m is determined as the distance. The direction is determined to be directed from the first location towards the second location.
In one embodiment, each of the plurality of preset directions may correspond to each of the arm units 200. When the number of arm units 200 is six, orientations divided into six (6) directions may be used, and a direction closest to an angle formed by the second position and the first position may be selected. For example, when it is assumed that north is 90°, 0°, 60°, 120°, 180°, 240° and 300° may be determined as directions corresponding to the six arm units 200. When the angle formed by the second position and the first position is 190°, a direction corresponding to 180° may be selected. A direction indicator may be formed on at least two of the arm parts 200, and an azimuth meter (not shown) may be included in the kit 10. Hence, the user can arrange the kit 10 such that the arm units 200, on which the direction indicators are formed among all of the arm units 200, correspond to the azimuth meter.
The light emitting module controller 102 may control the first light emitting module 213 and the second light emitting module 223 of the arm unit 200 corresponding to the direction to emit light in a pattern corresponding to the distance (S340).
The light emitting module controller 102 selects the arm unit 200 corresponding to the direction among all of the arm units 200.
The first light emitting module 213 and the second light emitting module 223 may include a plurality of LED modules, while the light emitting module controller 102 may control the LED modules corresponding to the distance to emit light.
A plurality of distance ranges and the number of LED modules are matched, respectively, and stored in the database 180 of the kit 10 in advance, and the light emitting module controller 102 may select the number of LED modules matching with the distance and then control the selected number of LED modules to emit light.
In one embodiment, the light emitting module controller 102 may select the number of LED modules matching with the distance in the order of proximity to the base plate 110 and then control the selected LED modules to emit light.
Therefore, the distressed person receiving the rescue signal can grasp the information that the rescuer is coming for rescue, as well as a direction of the rescuer approaching the distressed person and a distance between the rescuer and the distress person, and the like.
