In general, people use their vacation or leisure time to relax or enjoy hobbies while playing or swimming in a water park or swimming pool. There is always a risk of being sucked into this airway and causing breathing difficulties and suffocation.

As such, when water is sucked into a person's airways and death occurs due to suffocation, it is called drowning.

Often, when a person falls into the water, they can scream for life while struggling, so it is easy for people around to recognize this to be mistaken for being able to rescue the drowning person easily. is difficult to recognize from the outside, and it is almost impossible to shout out loud for help, especially since in most cases the drowning person often suffers from shortness of breath.

This type of drowning leading to drowning accidents tends to occur more frequently, especially in the case of children and the elderly, even when there are many people around, when there are security guards watching, or even when a swimming instructor is nearby. Since drowning accidents occur, it is necessary to develop technologies to prevent them.

Conventional technology for preventing drowning of drowning people can be divided into a technology related to water play equipment such as a life jacket, a technology related to the drowning prevention configuration of the water playground itself, and a drowning prevention technology using articles worn by a user who plays in the water. .

A method of controlling a drowning prevention wearable device according to an embodiment of the present invention having the above configuration will be described in more detail using the flowchart shown in FIG. 3 .

While the user starts operation while wearing the drowning prevention wearable device according to an embodiment of the present invention on a part of his or her body such as a wrist, the user's heart rate, the user's operation, etc. This is detected and the water pressure by the water pressure sensor is also sensed (S100).

Specifically, a change in gravitational acceleration by an acceleration sensor is sensed, and a user's motion is sensed by detecting a rotation in three axes by a gyro sensor, and a heartbeat of the user is sensed by a heart rate sensor. And the water pressure sensor detects the water pressure.

The detection results of these various sensors are transmitted to the control unit, and the control unit analyzes the detection results of these sensors (S110), and determines whether a drowning accident has occurred to the user (S120).

The control unit presets heart rate pattern information and behavior pattern information of the drowning person.

The heart rate of a person in a normal state beats very high when drowning in water. The data is accumulated and analyzed in advance to determine what heart rate pattern the drowning person will have. Therefore, it can be set in advance in the control unit (this will be referred to as 'preset heart rate pattern information of the drowning person').

In addition, there is a marked difference between the behavior of a person playing in the water and the behavior of a drowning person when a drowning accident occurs. As a result of accumulating and analyzing data through experiments in advance regarding the sensing value of the gyro sensor and the drowning person, a change pattern of the sensing value of the accelerometer and the gyro sensor according to the behavioral pattern of a typical drowning person or a predetermined value derived using the sensing value Information such as the range of the function value may be preset in the control unit (this will be referred to as 'pre-set behavior pattern information of the drowning person').

As described above, the control unit presets the heartbeat pattern information and behavioral pattern information of the drowning person, compares the user's heartbeat information detected by the heartbeat sensor with the preset heartbeat pattern information, and determines the detected heartbeat pattern. It may be determined whether a preset heartbeat pattern is similar to a preset standard or more.

And, for example, the controller may calculate a predetermined function value using the respective sensing values of the acceleration sensor and the gyro sensor, and determine whether the calculated value is included in a range of a preset value.

As described above, when the sensing result of the heart rate sensor and the sensing result of the acceleration sensor and the gyro sensor all correspond to the heart rate pattern information and behavior pattern information of the drowning person, the control unit may cause a drowning accident to the user currently wearing the wearable device. It can be determined that it has occurred (S120).

When a drowning accident occurs to the user, the control unit directly drives the separation drive unit (250, see FIG. 2) to operate the first and second operation support parts (351, 352, see FIG. 2) to operate the operating device 200. It is separated from the wearable body 100 .

Here, some examples of the driving of the separation driving unit and the operation support unit will be described with reference to FIG. 4 .

The separation driving unit may be implemented as a single motor that simultaneously drives the first and second operating supporting units through a cam or power transmission means, or a solenoid and second operating supporting units for driving the first operating supporting unit. It may be implemented as a driving solenoid, or it may be implemented in a configuration such that one solenoid drives the first operation support part and the second operation support part at the same time.

4 (a) and (b) are the first solenoid 251 for driving the first operation support part 351 and the second solenoid 252 for driving the second operation support part 352, the separation driving part is implemented An example is shown, in Fig. 4 (a), the first operation support part 351 and the second operation support part 352 protrude and are caught in the accommodation support part 112 (refer to FIG. 1) so that the operating device is the accommodation part 110, FIG. 1 refer), in Fig. 4 (b), the first solenoid 251 operates to pull the first operation support 351, and the second solenoid 252 operates to operate the second operation support 352. It indicates the state in which the operating device is separated from the receiving part by pulling the .

4 (a) and (b) show the configuration in which two solenoids respectively drive the operation support part, it is also possible to configure the first operation support part and the second operation support part to be driven simultaneously with one solenoid .

On the other hand, in (c) and (d) of Figure 4, using one motor 253 and the operation pins 261 and 262 as power transmission means, the first operation support part 351 and the second operation support part 352 at the same time. An example of driving is shown.

As shown in (c) of FIG. 4 , the motor 253 and the first operation support part 351 are connected by the first operation pin 261 , and the second operation support part 352 and the second operation support part 351 are connected to the second operation pin 262 . ), as the motor 253 rotates and drives the first operation pin 261 and the second operation pin 262 to rotate as shown in FIG. 4 (d), the first operation pin The first operation support part 351 connected to the 261 may be pulled, and the second operation support part 352 connected to the second operation pin 262 may be attracted.

The configuration and operation shown in FIG. 4 are shown in some examples, and the present invention may include all configurations capable of simultaneously driving the first operation support part and the second operation support part using a single motor.

Returning to FIG. 3 again, as described above, the operation device, in which the locking state is released by pulling the first operation support part and the second operation support part by the operation of the separation driving part, respectively, is separated from the wearable body and floats on the water (see FIG. 1 ). ).

As for the operating device floating on the water, the sound module 320 (refer to FIG. 2) is driven by the control unit to output a preset rescue request sound, and the LED module (330, see FIG. 2) is driven to provide a preset pattern of rescue request lighting. It can be output to alert people around the rescue request (S140).

In addition, the control unit of the operating device transmits, for example, a beacon signal through the wireless communication unit 510 (refer to FIG. 2) to operate a warning light notifying the occurrence of an accident through a beacon terminal installed around the water playground. A rescue request can also be made by transmitting a wireless signal to the control center through the AP installed inside the field (S150).

A more specific example of this will be described with reference to FIG. 5 .

5 is a water playground (PL) and a plurality of warning lights (ML) of a beacon communication method installed in the vicinity, and an AP (Access Point) connected to a server (SV), communication with a control center (CS) that can be networked through the AP It shows about a safety officer (SG) wearing a possible wearable device.

In the state shown in FIG. 5 , when a drowning person Pd occurs, the operating device of the drowning prevention wearable device according to an embodiment of the present invention worn by the drowning person Pd is removed from the wearable body as described above. It is separated and floats on the water, and the operating device 200 that floats on the water outputs a rescue request sound and light, and sends a beacon signal so that the surrounding warning lights (ML) operate, so that people around them recognize the drowning person and rescue them. make it possible

In addition, the wireless signal transmitted by the operating device is transmitted to the wearable device of the safety personnel (SG) through the AP, so that the safety personnel can be informed that a drowning person has occurred, and the rescue is saved by notifying the control center (CS) of the occurrence of the drowning person. related processes (eg, broadcasting inside the water park to notify that a drowning person has occurred, etc.) may be executed.

As described above, the drowning prevention wearable device and the control method thereof according to the present invention not only detect or monitor the occurrence of a drowning accident of a user playing in water, but also separate the operating device from the wearable device worn by the user. It is a big deal in that drowning prevention can be performed more effectively by making the floating device float on the water and allowing the floating device to execute various methods for an active rescue request so that the rescue of the drowning person can proceed more actively. There are advantages.
