1 is a block diagram of a lifesaving system.

Referring to FIG. 1 , the lifesaving system of the present invention includes a lifesaving device 100 and a lifesaving management server 200 .

The lifesaving device 100 is a device carried by a user and can be used in the sea or in the mountains. The plurality of lifesaving devices 100 may communicate with the lifesaving management server 200, respectively, or may communicate with each other. It is preferable that the lifesaving device 100 includes a battery 111 therein and can be charged and used. The lifesaving device 100 generates an emergency signal and transmits it to the lifesaving management server 200 . The lifesaving apparatus 100 may generate location information and transmit it as an emergency signal. The lifesaving device 100 is preferably formed in a waterproof, dustproof type. The lifesaving device 100 communicates with the lifesaving management server 200 through a network, and the method may vary according to user settings.

The lifesaving management server 200 monitors at least one lifesaving device 100 . When an emergency signal is received from the lifesaving device 100 , the lifesaving management server 200 analyzes the location information and transmits the rescue signal to the rescue center or the nearby lifesaving device 100 . The lifesaving management server 200 determines whether the lifesaving device 100 is in a normal mode or an emergency mode. The lifesaving management server 200 may be linked with the rescue center to quickly transmit a rescue signal. The lifesaving management server 200 is connected to the Meteorological Agency server or the disaster center server, and it is also possible to receive disaster-related information and alert the lifesaving device 100 . The lifesaving management server 200 may collect movement information of the lifesaving device 100 and model the movement path through big data analysis.

Hereinafter, the lifesaving device 100 will be described in detail.

2 is a block diagram of a lifesaving device according to an embodiment of the present invention, FIG. 3 is a detailed configuration diagram of a body part of the lifesaving device according to FIG. 2, and FIG. 4 is a safety area of the lifesaving device according to FIG. It is an exemplary view for explaining the transmission of a warning signal when deviating, Figure 5 is an exemplary view for explaining that the tube is mounted on the body portion of the lifesaving device according to FIG.

1 to 5 , the lifesaving device 100 according to an embodiment of the present invention includes a body 110 , a first communication unit 120 , a position sensing unit 130 , and a first control unit 140 . include

The body 110 accommodates the first communication unit 120 , the position sensing unit 130 , and the first control unit 140 therein. The body 110 may be formed of a synthetic resin material or a metal material. The size of the body part 110 may be changed by a user's design, and it is preferable to be formed in a shape that the user can hold by hand. A battery 111 may be mounted on the body 110 . The battery 111 may be a secondary battery, and may be integrally or detachably formed in the body 110 . The capacity of the battery 111 of the body 110 may be changed by a user's design. It is preferable that the body part 110 is formed in a sealed structure so that it can be waterproof and dustproof therein.

In addition, an emergency button 112 is formed on one side of the body 110 . The emergency button 112 generates a control signal for driving the first control unit 140 . For example, when the emergency button 112 is operated by the user, the location information of the location detection unit 130 may be transmitted to the external lifesaving management server 200 through the first communication unit 120 . The emergency button 112 of the body 110 is also capable of generating another control signal by the number of times it is pressed. For example, when the emergency button 112 is pressed once, location information is transmitted to the outside, and when the emergency button 112 is pressed twice, a warning signal or the like can be received from the outside. Accordingly, the user can easily transmit an emergency signal or receive an external warning signal by manipulating the emergency button 112 according to his or her situation.

In addition, the body part 110 may be formed with a whistle part 113 capable of making a whistle sound on one side. The whistle part 113 is formed in a structure in which a sound of a preset wavelength can be output when the user blows air through breathing. The whistle unit 113 is to notify the user of an emergency through a whistle sound in a situation such as when the battery 111 is discharged inside the body unit 110 . The volume of the sound generated by the whistle unit 113 may vary according to the user's design. Accordingly, even when an electronic signal cannot be transmitted, an emergency signal may be generated through the whistle unit 113 .

In addition, identification information may be displayed on the outside of the body part 110 . Here, the identification information is for authenticating the user, and a QR code may be used, but is not necessarily limited thereto. When the user acquires the identification information of the lifesaving device 100 through the user terminal 10 and transmits it to the lifesaving server, user registration is completed. The user may obtain the identification information again through the user terminal 10 to authenticate the use completion, and thus the termination process may be performed. Accordingly, the lifesaving management server 200 can identify the lifesaving device 100 used by the user and track the history thereof.

In addition, a tube 114 that expands when in contact with water may be embedded in the body 110 . For example, the tube 114 may be equipped with a compressed gas cylinder to inflate the tube. In more detail, the tube 114 may be expanded by being perforated by the compressed gas cylinder when water contact is sensed by the moisture sensor, but is not limited thereto. When receiving a puncture control signal by the control signal of the first control unit 140 or lifesaving management server 200 to be described later, it is also possible to puncture the compressed gas cylinder so that the tube 114 expands. Accordingly, even when the user is in distress at sea, it is possible to cope with an emergency situation by using the tube 114 .

The first communication unit 120 communicates with an external management server. The first communication unit 120 is capable of short-range or long-distance communication. For example, the first communication unit 120 may communicate through at least one of Bluetooth communication, RF communication, 3G, 4G, 5G, Wi-Fi communication, and satellite communication. The first communication unit 120 may operate in a one-way communication mode. For example, in the case of one-way communication mode, it is waiting in a sleep state, and when the emergency button 112 is operated, it is activated to transmit an emergency signal to the lifesaving management server 200 . This is to minimize power consumption of the internal battery 111 .

Also, the first communication unit 120 may operate in a two-way communication mode. This is to receive an alarm signal from the external lifesaving management server 200 . Here, the warning signal may include weather information, dangerous area information, and the like. The first communication unit 120 may also receive a rescue signal from the lifesaving device 100 or the lifesaving management server 200 in an adjacent area. The rescue signal may include location information of the user who has transmitted the emergency signal. The first communication unit 120 may switch between the one-way communication mode and the two-way communication mode according to the number of driving times of the emergency button 112 .

The position sensing unit 130 detects position information of the body unit 110 . For example, the location detecting unit 130 may generate coordinate information as location information using GPS. The position sensing unit 130 operates in the sleep mode, and is activated when the emergency button 112 operates to generate position information. In this case, the location information may be transmitted to the external lifesaving management server 200 . The position sensing unit 130 is activated at a preset time period to generate position information. It is also possible for the position detection unit 130 to transmit past position information in addition to the current position information to the external lifesaving management server 200 . This is to determine the user's current location as well as the past location to determine which route the user has moved.

When the emergency button 112 is operated by the user, the first control unit 140 transmits an emergency signal including location information to the management server. The first control unit 140 may store the user's location information and unique identification information of the lifesaving apparatus 100 through its own memory. When the emergency button 112 is operated, the first control unit 140 may transmit an emergency signal including location information and identification information. After the emergency signal is transmitted, the first control unit 140 may switch the first communication unit 120 from the one-way communication mode to the two-way communication mode. This is to receive a response signal from the external lifesaving management server 200 . In this case, it is possible for the first communication unit 120 to transmit an emergency signal even to the adjacent lifesaving apparatus 100 that is adjacent thereto. This is to quickly request help from nearby users.

Also, the first control unit 140 may transmit an emergency signal to the lifesaving management server 200 when the user's location information is out of a preset safe area. In this case, when a user approaches a military area or an accident caution area in an area such as the sea or a mountain, it is determined that the user is out of the safety area and an emergency signal can be generated. In this case, it is also possible for the first control unit 140 to transmit the emergency signal at a predetermined time period after transmitting the emergency signal to the lifesaving management server 200 . This is to enable the user to track the location if he or she is out of the safe zone. Accordingly, even when there is no operation of the emergency button 112 by the user, it is possible to prevent a safety accident by transmitting an emergency signal using the location information.

Meanwhile, the lifesaving apparatus 100 according to an embodiment of the present invention may further include an alarm unit 150 .

The alarm unit 150 outputs an alarm signal using a speaker or a lighting lamp formed in the body unit 110 . For example, the alarm unit 150 may automatically operate even when the user leaves the safe area A. This is to notify the user when he/she approaches the danger area without being aware of it. The alarm unit 150 may output an alarm signal in the form of a voice. For example, it is possible to output a weather forecast or a caution guide for a dangerous area in the form of a voice to draw the user's attention.

In this case, the first control unit 140 drives the alarm unit 150 when receiving an alarm signal from the lifesaving management server 200 . For example, when the alarm signal is text, the first control unit 140 may convert the voice signal to output it. This is to easily notify the user by converting the alarm signal into voice when the user on the move cannot check the text. It is also possible for the first control unit 140 to automatically generate an alarm signal even when out of the safety area (A) by using the location information of the lifesaving device (100). Accordingly, safety accidents can be prevented in advance.

Meanwhile, the lifesaving device 100 according to an embodiment of the present invention may further include an environment sensing unit 160 .

The environment sensing unit 160 generates environment sensing information of at least one of temperature, humidity, illuminance, moisture, gas concentration, vision image, and thermal image of the sensing target. For example, the environment sensing unit 160 may include a temperature sensor, a humidity sensor, an illuminance sensor, a moisture sensor, a camera, and the like. The environment sensing unit 160 collects the surrounding environment information and transmits it to the external lifesaving management server 200 to determine the user's environmental condition. For example, in the event of a fire, the surrounding temperature, illuminance, vision image, etc. are transmitted together with an emergency signal to enable a more accurate understanding of the on-site situation.

In this case, the first control unit 140 may analyze the sensing information to determine the sensing target as any one of the air, the ocean, and the mountain, but is not limited thereto. For example, the first controller 140 may determine whether the sensing target is the air, the ocean, or a mountain using temperature, humidity, illuminance, and the like. This is to more precisely understand the user's current surrounding environment and generate an emergency signal accordingly. For example, in the case of a user in distress in a mountain, an emergency signal is transmitted to a mountain rescue team, and in the case of a user in distress in the sea, an emergency signal may be transmitted to the marine rescue team.

The first control unit 140 transmits an emergency signal to the lifesaving management server 200 when the detection information on the detection target is out of a preset reference range. For example, the reference range may determine whether a fire exists based on the temperature or gas concentration in the atmosphere. The reference range can be judged as marine distress depending on whether moisture is detected. For example, when the first control unit 140 determines that the detection target is the air and a fire occurs outside the reference range, an emergency signal is transmitted to a fire station or a military unit so that the fire can be extinguished early.

Meanwhile, the lifesaving apparatus 100 according to an embodiment of the present invention may further include a motion detection unit 170 .

The motion detecting unit 170 senses at least one or more motion information among vibration, inclination, speed, and acceleration of the body unit 110 . For example, the motion detection unit 170 may include a vibration sensor, a gyro sensor, an acceleration sensor, a pressure sensor, and the like, but is not necessarily limited thereto. The motion detection unit 170 is activated when a motion exceeding a preset reference range is detected while waiting in the sleep mode to generate motion detection information. This is to minimize power consumption. The motion detection unit 170 outputs motion detection information to the first control unit 140 . This is to be used as basic data for judging whether a user's movement is detected.

In this case, the first control unit 140 transmits an emergency signal to the lifesaving management server 200 when the movement information is out of a preset reference range. Here, the reference range represents a movement outside of normal walking or running, and is used as a reference for classifying movement such as a fall. When the motion information is out of a reference range, the first controller 140 may track the motion along with the location information. This is to determine the user's injury information or an emergency situation according to the presence of additional movement information.

Also, after the motion information deviates from the reference range, the first controller 140 may continuously transmit the emergency signal when there is no change in the motion information for a preset time. This is to determine that the user is in an emergency state, unconscious or unable to use the body, and continuously transmits emergency signals to notify them. The first controller 140 may not transmit an emergency signal when the motion information is detected for a preset time even when the motion information is out of the reference range. For example, if a movement out of the reference range is detected when a person stumbles in a mountain, and a movement is detected for a preset time thereafter, it may be determined that the situation is not urgent.

In addition, when the tube 114 of the body 110 is inflated, the first control unit 140 may transmit the user's status to the lifesaving management server 200 by using motion information detected in the tube 114 . have. For example, the first control unit 140 may detect a change in pressure after the tube 114 is expanded to determine the state of the person in distress. When the pressure of the tube 114 changes from the first value to the second value, it is determined that the tube 114 has expanded. When the pressure of the tube 114 changes from the second value to the third value, it is determined that the user grips the inflated tube 114 . Accordingly, it is possible to more accurately grasp the state of the user who is in distress remotely.

Meanwhile, the lifesaving apparatus 100 according to an embodiment of the present invention may further include a sound sensing unit 180 .

The sound sensing unit 180 detects the user's voice or sound information around the user. For example, the sound sensing unit 180 may include a microphone. The sound sensing unit 180 may detect as sound information when a sound greater than or equal to a reference range is sensed. The sound sensing unit 180 may sense the size or frequency of the sound and sense it as sound information. The sound sensing unit outputs sound information to the control unit. The sound information of the sound sensing unit 180 is transmitted together with an emergency signal so that an external rescuer can grasp the user's emergency situation in advance.

In this case, when sound information is detected, the first controller 140 may record it. The recording file may be stored through the internal memory of the first controller 140 . When transmitting the emergency signal, the first control unit 140 transmits sound information in the form of audio or text. The first control unit 140 may provide sound information while minimizing the data of the emergency signal. For example, the first controller 140 may reduce the data size by adjusting the sampling frequency of the sound information. The first control unit 140 may analyze the voice of the sound information and automatically transmit it to the lifesaving management server 200 as an emergency signal when it matches the pre-stored emergency signal.

On the other hand, the lifesaving apparatus 100 according to the embodiment of the present invention may further include a biometric sensor 190 .

The biometric sensor 190 detects biometric information including the user's body temperature, heart rate, blood pressure, and the like. For example, the biosensor 190 may sense body temperature or heart rate using a biosensor. The bio-sensing unit 190 may be formed in the form of an electrode on one side of the body unit 110 , but is not limited thereto. The biometric sensor 190 detects the user's current health state and outputs the biometric information to the first controller 140 to transmit the biometric information together with the emergency signal. The biometric sensor 190 may generate biometric information when the emergency button 112 is operated while waiting in the sleep mode. In this case, the biometric sensing unit 190 may be formed on the emergency button 112 so that the user can sense biometric information when operating it.

In this case, the first control unit 140 may transmit an emergency signal to the lifesaving management server 200 when the biometric information is out of a preset safe range. For example, when a user falls into water or falls from a mountain, the user's biometric information is transmitted together with an emergency signal. The first control unit 140 may transmit the biometric information to the lifesaving management server 200 at a preset time period. This is to continuously monitor the user's health status. The first controller 140 may transmit the biometric information at a first time period when the biometric information is within the safe range, and transmit the biometric information at a second time period when the biometric information is out of the safe range. This is to understand the current biometric information more accurately by shortening the transmission period of the biometric information in the case of a dangerous situation.

1) Monitoring through sound recognition sensor

The first controller 140 may sense sound information of at least one of an ambient environment sound and a voice of a survivor through the sound recognition sensor. In this case, the sound recognition sensor may be included in the first sensor unit 131 .

The first control unit 140 detects an abnormal situation of a person in distress using the first learning model related to sound recognition based on the sensed sound information, and transmits a rescue request signal or an additional action request signal to the lifesaving management server 200 . can do.

Here, the abnormal situation means a distress situation, for example, a situation in which an overturning or drowning accident occurs on water or at sea, or a situation in which a fall or trip accident occurs in a mountainous area.

That is, when an accident occurs through the sound recognition sensor built into the lifesaving device 110 , an abnormal situation can be detected by recognizing the sound of the surrounding environment, the voice of a person in distress, or the sound of a whistle.

For example, when an overturning accident occurs at sea, the sound recognition sensor built into the lifesaving device 100 carried by the person in distress or delivered to the person in distress (via a vehicle) can detect the voice of the shipwreck, for example, " When recognizing the sentence "Please help me" or recognizing the whistle sound connected to the tube 114, the recognized sound information

It can be determined that an accident situation has occurred by analyzing the first learning model.

Accordingly, the first control unit 140 may transmit a rescue request signal or an additional action request signal to the lifesaving management server 200 together with the location information of the distressed person sensed by the GPS location sensor.

Here, the first learning model is a learning model to which an artificial intelligence algorithm related to sound recognition is applied, and may be constructed by learning various sounds that may appear in a distress situation.

The first control unit 140 may analyze sound information sensed through the first learning model, for example, ambient sound, and predict whether an accident occurred at sea or water or a mountain area.

The first control unit 140 may analyze the sound information sensed through the first learning model and the voice of the person in distress, and predict the distance between the person in distress and the lifesaving device 110 . If the distance between the person in distress and the lifesaving device 110 is greater than the preset reference distance, it is determined that the person in distress cannot acquire the lifesaving device 110 , and the first control unit 140 takes additional measures to the lifesaving management server 200 . A request signal can be sent.

According to the embodiment, even when the sound information sensed by the sound recognition sensor is not clear due to the inaccuracy of the voice of the distressed, the noise of the surrounding environment, the limitation of communication, etc., the sound information is obtained using the first learning model. By analyzing and predicting the contents of the sound information, it is possible to detect anomalies. Alternatively, by analyzing the sound information and expressing it in other forms, such as textualization, light or color change, vibration, etc., it is possible to take appropriate measures according to the situation.

2) Monitoring via pressure sensor

The first control unit 140 may receive pressure change information for the tube sensed by the pressure sensor from the communication module through the first communication unit 120 . In this case, the pressure sensor and the communication module may be included in the second sensor unit 132 .

The first control unit 140 may determine whether the person in distress is holding the tube based on the pressure change information, and may transmit a rescue request signal or an additional action request signal to the lifesaving management server 200 based on the determined result.

Specifically, when the pressure applied to the tube 114 changes from the first value to the second value based on the pressure change information, the first control unit 140 determines that the tube 114 has expanded, When the pressure applied to 114 changes from the second value to the third value, it may be determined that the person in distress has gripped the inflated tube 114 .

The pressure applied to the tube 114 in a state in which the tube 114 is not inflated (ie, embedded in the body portion) may be a first value, and the tube 114 is in an inflated state (ie, separated from the body portion). state), the pressure applied to the tube 114 may be the second value. In this case, the second value may be greater than the first value. In addition, the pressure applied to the tube 114 in a state where the victim grips the inflated tube 114 may be a third value. In this case, the third value may be greater than the second value.

Accordingly, when the pressure applied to the tube 114 changes from the first value to the second value, the first control unit 140 determines that the tube 114 is separated from the body 110 and expanded in contact with water. can judge When the pressure applied to the tube 114 changes from the second value to the third value, the first control unit 140 may determine that the victim has secured the inflated tube 114 .

And, based on the determined result, when the tube 114 is inflated but the survivor does not hold the inflated tube 114, the first control unit 140 transmits an additional action request signal along with the location information of the survivor and , when the tube 114 is inflated and the survivor grips the inflated tube 114 , a rescue request signal may be transmitted along with the position information of the survivor.

That is, when it is determined that the tube 114 is inflated but the survivor does not grip the inflated tube 114 (ie, the pressure applied to the tube 114 changes from the first value to the second value, but the second value) In case it does not change to the third value), the first control unit 140 determines that the distressed person has not secured the inflated tube 114, and sends an additional action request signal such as an additional kit delivery request to the lifesaving management server ( 200) can be sent.

When the tube 114 is inflated and the survivor grips the inflated tube 114 (ie, the pressure applied to the tube 114 changes from the first value to the second value and back to the third value) , the first control unit 140 may determine that the person in distress has secured the inflated tube 114 and transmit a rescue request signal such as a rescue team call request to the lifesaving management server 200 .

By using the pressure sensor to determine whether the victim is holding the tube, it is possible to more quickly determine the position of the person in distress when there are a plurality of kits around the person in distress.

For example, when a sea overturn accident occurs, several lifesaving devices 110 are thrown to the side of the survivor or delivered through a carrier in order to save lives. At this time, the GPS sensed by each lifesaving device 110 Because the location information is emitted, it is impossible to accurately determine which lifesaving device 110 among the plurality of lifesaving devices 110 has a survivor (that is, which tube 114 the survivor is holding), so the terminal 20 may cause difficulties in monitoring the condition of the distressed.

Therefore, the pressure change applied to the tube 114 is sensed using the pressure sensor, and accordingly, it is possible to determine which tube 114 the victim has gripped from the plurality of tubes 114, and the tube 10 is It is possible to save lives quickly and efficiently by tracking only the emitted GPS location information.

3) Monitoring using acceleration sensor or vibration sensor

The first control unit 140 may sense information on the change in acceleration of the victim through the acceleration sensor, and sense information on the occurrence of impact of the victim through the vibration sensor. In this case, the acceleration sensor and the vibration sensor may be included in the first sensor unit 131 .

The first control unit 140 may detect an abnormal situation based on the sensed acceleration change information and transmit a rescue request signal or an additional action request signal to the lifesaving management server 200 .

That is, when an accident occurs, for example, when a fall from a ship, a fall from a rock or a cliff, etc. occur, an abnormal situation can be detected through a change in the acceleration of the lifesaving device 110 carried by the person in distress.

In more detail, when the acceleration of the lifesaving device 110 carried by the person in distress maintains a constant value and suddenly increases to a difference greater than or equal to a preset value, it can be determined that an abnormal situation has occurred.

According to an embodiment, the first control unit 140 detects an abnormal situation by combining the acceleration change information and the shock occurrence information, and when the abnormal situation is detected, a rescue request signal or an additional action request signal to the lifesaving management server 200 You can also send

That is, when an accident occurs, for example, a fall from a boat, a fall from a rock or cliff, an abnormal situation can be detected through the change in acceleration and the strength of the lifesaving device 110 carried by the person in distress. can

In more detail, when the acceleration of the lifesaving device 110 carried by the person in distress maintains a constant value and abruptly increases to a difference greater than or equal to a preset value, and at the same time, when the shaking intensity becomes greater than a preset value, it can be determined that an abnormal situation has occurred. have.

As described above, the present invention uses a sound recognition sensor, a pressure sensor, an acceleration sensor, and a vibration sensor to detect an abnormal situation of a person in distress, and according to the situation, a rescue request signal or an additional action request signal is transmitted to the remote terminal to save lives. Although the rescue management server 200 can monitor the situation of the survivor, according to an embodiment, one or more sensors among a plurality of sensors included in any one of the first sensor unit 131 and the second sensor unit It is also possible to monitor the condition of the distressed by using the sensing result by the

On the other hand, the body part 110 is formed to be coupled and detachable from the carrier using the link of the joint structure formed on the upper surface, so that the lifesaving device 110 can be delivered to the person in distress.

As described above, the person in distress may be in a distress situation while already carrying the lifesaving device 100 , but may be in a distress situation without the lifesaving device 110 . In this case, the lifesaving device 110 may be delivered to the person in distress through a carrier (eg, a drone).

For this case, the link 110-3 of the joint structure is included on the upper surface of the first part 112 as shown in FIG. 8, and may be formed to enable coupling and separation with the carrier. Specifically, the lifesaving device 110 is combined with and separated from the carrier through the rotation or horizontal movement of the link 110-3 of the joint structure, so that the lifesaving device 110 is a disaster accident occurring in the sea, water, or mountainous area. can be passed on to the victim.

Depending on the embodiment, vaccines, emergency medicines, etc. may be embedded in the lifesaving device 110 , and the goods may be delivered to people who cannot easily obtain vaccines or emergency medicines in island areas through a carrier.

According to the embodiment, the first control unit 140 learns the difference between the sensing result when the lifesaving device 110 is successfully delivered to the distressed by the carrier and the sensing result when the kit fails to be delivered to the distressed by the carrier by learning the difference between the kit A second learning model related to delivery can be built.

That is, the second learning model transmits the sensing result and transfer when the transfer is successful by at least one sensor among the plurality of sensors included in the first sensor unit 131 or the second sensor unit 132 in the lifesaving device 110 . It can be built by learning the sensing result in case of failure and learning the difference in each case.

As an example, the second learning model uses the sensing result of the GPS position sensor to data the movement of the life-saving device 110 when delivery to the distressed is successful and the movement of the life-saving device 110 when the delivery fails and learn. can do.

As another example, the second learning model may use a gravity sensor or an acceleration sensor to data and learn the difference in acceleration or movement due to the difference in gravity of the lifesaving device 110 when delivery to the distressed is successful and when it fails.

The first control unit 140 analyzes the sensing results transmitted in real time from the lifesaving device 110 when the lifesaving device 110 is delivered through the second learning model and predicts the correct path, so that the lifesaving device 110 delivery success rate can increase

Meanwhile, the lifesaving management server 200 may manage the lifesaving device 110 by using information related to consumables included in the lifesaving device 100 .

Specifically, the user or the rescuer checks maintenance information such as the replacement cycle and use history of consumables, for example, the tube 114, the compressed gas cylinder, etc. through the application installed in the lifesaving management server 200, and through this Consumables of the lifesaving device 110 may be replaced or cleaned at an appropriate time. In addition, information related to the battery charging status of the lifesaving device 110 and movement, on/off state, and usage status of the lifesaving device 110 can be checked, and the lifesaving device 110 can be managed through this.

The third sensor unit (not shown) may sense a distress situation image using a vision sensor. In this case, the vision sensor may include a general camera module (EO) and a thermal imaging camera module (IR).

That is, the first control unit 140 may transmit the distress situation image captured by the general camera module (EO) and the thermal imaging camera module (IR) included in the vision sensor to the lifesaving management server 200 .

Accordingly, the user or the rescuer can visually monitor the distress situation through the distress situation image received by the lifesaving management server 200 .

According to an embodiment, the first control unit 140 converts the general image or the thermal image captured by the thermal imaging camera module according to the quality or resolution of the general image photographed by the general camera module to the lifesaving management server 200 . can be sent to In this case, the distress situation image may be a general image or a thermal image.

As another example, the first controller 140 determines that the image quality or resolution of a general image captured by the general camera module falls below a preset level due to various reasons such as weather and accident site conditions, and the image quality or resolution is lowered. The thermal image captured by the thermal imaging camera module together with the general image may also be transmitted to the lifesaving management server 200 .

On the other hand, FIG. 9 is a configuration diagram of a lifesaving server according to an embodiment of the present invention, and FIG. 10 is an exemplary diagram for explaining authentication of a user using a user terminal in the user management unit of the lifesaving server according to FIG. , FIG. 11 is an exemplary diagram for explaining the creation of a movement model in the monitoring unit of the lifesaving server according to FIG. 9 .

The second communication unit 210 communicates with the lifesaving device 100 . For example, the second communication unit 210 may communicate through at least one of Bluetooth communication, RF communication, 3G, 4G, 5G, Wi-Fi communication, and satellite communication. The second communication unit 210 may receive an emergency signal from the first communication unit 120 of the lifesaving device 100 . The second communication unit 210 may operate in a one-way communication mode to only perform a reception function, or may operate in a two-way communication mode. The second communication unit 210 may also transmit a rescue signal for the emergency signal to the proximity lifesaving apparatus 100 .

The user management unit 220 manages user information. The user management unit 220 may authenticate the user when the identification information formed in the lifesaving device 100 is obtained and authenticated by the user terminal 10 . This is for authenticating a user who is currently using the lifesaving device 100 , and can be used by authentication at the start and end times of using the lifesaving device 100 , respectively. Here, the identification information may be a QR code, but is not necessarily limited thereto. The user management unit 220 may check the user's personal information or contact information through the application of the user terminal 10 .

The monitoring unit 230 monitors the emergency signal. The monitoring unit 230 monitors whether an emergency signal is received from the lifesaving device 100 . In this case, the monitoring unit 230 may monitor the emergency signals from the plurality of lifesaving devices (100). For example, the monitoring unit 230 may monitor the plurality of lifesaving devices 100 when used by several people, such as at a beach or in a mountain. The monitoring unit 230 may determine whether the emergency signal is normal. For example, when an emergency signal is generated in a place other than a dangerous area, it is possible to process the emergency signal as a bad signal. This is to prevent unnecessary rescue teams from being dispatched when the user erroneously manipulates the emergency signal.

Also, the monitoring unit 230 may determine whether the lifesaving apparatus 100 is in a normal mode or an emergency mode. For example, the monitoring unit 230 may simply monitor the movement path when the lifesaving apparatus 100 is in the normal mode. The monitoring unit 230 may analyze the user's location by analyzing the real-time location when the lifesaving device 100 is in the emergency mode. The monitoring unit 230 may also monitor the state of the battery 111 of the lifesaving device 100 . When the remaining amount of the battery 111 of the lifesaving device 100 is less than a preset value, the monitoring unit 230 may switch to the emergency mode and monitor. This is to confirm the final location in preparation for the loss of communication with the lifesaving device 100 in a state in which the user is not aware.

The second control unit 240 analyzes the location information when receiving an emergency signal from the lifesaving device 100 . The second control unit 240 transmits the analyzed location information of the lifesaving device 100 to the rescue center or the lifesaving device 100 and the proximity lifesaving device 100 located within a preset distance. This is to request help not only from the rescue team but also from the lifesaving device 100 that has transmitted an emergency signal and the proximity lifesaving device 100 located within a preset proximity. Accordingly, before the rescue team of the rescue center arrives at the scene, the general user can arrive in advance and take initial countermeasures.

In addition, the second control unit 240 analyzes whether the emergency signal of the lifesaving device 100 is in the normal mode or the emergency mode in the monitoring unit 230, and in the case of the normal mode, the position of the lifesaving device 100 in a preset time period. A movement model 231 may be generated by analyzing the information. This is simply to analyze the moving path of a moving user and use it as big data. The second control unit 240 may strengthen monitoring of the main movement path by using the movement model 231 . The movement model 231 is formed in a graphic form so that the frequency or concentration of the movement path can be easily checked with the naked eye.

Also, the second control unit 240 may transmit an alarm signal to the lifesaving device 100 . For example, the second control unit 240 may generate an alarm signal when the lifesaving device 100 deviates from a preset safety zone or when a change in weather is expected. It is also possible to unidirectionally transmit such an alarm signal through the second communication unit 210 . The second control unit 240 may obtain weather forecast information from an external weather management server or the like and provide it as an alarm signal to the lifesaving device 100 . The second control unit 240 may also transmit an alarm signal when the location information of the lifesaving device 100 is out of a preset safe area or enters a dangerous area. In this case, it is preferable that the lifesaving device 100 is in a state in which communication is possible at all times.

Also, the second control unit 240 may analyze the location information of the lifesaving apparatus 100 to transmit additional information for each preset location. Here, the additional information may include, but is not limited to, history by location, tourist information, and usage guide information. It is preferable that the additional information is provided in the form of voice from the lifesaving device 100 . The second control unit 240 may provide when the lifesaving apparatus 100 moves to a location to which the additional information is mapped. Accordingly, in addition to simply risk information, additional information of the region can be provided, thereby providing convenience to the user.

Also, the second control unit 240 may set a different reproduction speed of the additional information according to the moving speed of the user. For example, if the moving speed of the user is faster than the average, the reproduction speed of the additional information may be increased, and if the user's moving speed is slower than the average, the reproduction speed of the additional information may be slowed down. The second control unit 240 may obtain movement information in addition to the location information of the lifesaving apparatus 100 to determine the user's movement speed or movement direction. Accordingly, the user may be provided with additional information according to each location while moving.

In the above, the present invention has been mainly described with reference to the preferred embodiments described with reference to the drawings, but is not limited thereto. Therefore, 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.
