Description

Smart watch and its control method {SMART WATCH AND CONTROLLING METHOD OF SAME}

The present invention relates to a wrist watch, and more particularly, to a smart wrist watch capable of determining the wearer's state by using the wearer's heartbeat.

Although child abuse occurring in our society is a serious social problem, awareness of its seriousness and danger was not great. In particular, it is true that the seriousness of the problem has been reduced and socially neglected because children cannot claim and defend their human rights due to their mental and physical immaturity. Recently, there have been many efforts to scientifically prevent these problems with the development of smart devices and the Internet of Things (IoT).

Republic of Korea Patent Publication No. 10-1914684 (announced date: December 28, 2018) prevents disappearance through a band-type wearable device worn on the wrist to prevent disappearance including the abduction of children How to do it is disclosed. It is a method to detect an electrocardiogram or sudden vibration, and to transmit it to the person in charge of protection or related organizations when it is out of the allowable range.

However, the ECG sensor that measures the ECG has a large error unless it is attached to the chest. Also, unlike disappearance, in the case of abuse, the biological response to the abuse is different, so it cannot simply be applied to the case of abuse. And, there is a risk of hacking personal biometric information because the measured data must be transmitted to the server every time.

According to Article 3, No. 7 of the Child Welfare Act, child abuse is physical, mental, or sexual violence or harsh acts that may harm the health and welfare of children or impede normal development by adults, including guardians, or by the guardians of children. It refers to abandonment and neglect. Physical abuse includes pushing and grabbing, slaps, kicking, biting and punching, and severe twisting of arms or legs. Emotional abuse also includes swearing at children, confinement, threatening to leave the house, using resentful or repulsive language, and coercing other children to abuse them.

In the case of such abusive behavior, the victim's body is placed in psychological states such as anxiety, agitation, and stress, so the sympathetic nervous system may be stimulated to release hormones called adrenaline or noradrenaline. This causes the heart muscle to contract, causing the heart rate or heart rate to rise. Alternatively, an irregular heartbeat may occur. And, the victim's breathing can become deep and rapid. Using the victim's biometric information can help to identify the abuse in real time.

An embodiment according to the present invention relates to a smart wristwatch capable of determining whether a wearer, in particular, children and infants are abused by using biometric information that is changed when it occurs due to child abuse, and a method for controlling the same. Here, according to the Convention on the Rights of the Child, etc., a child may mean a person under the age of 18. In other words, it can refer to a minor under the Civil Code of the Republic of Korea. Also, in this specification, a user or a wearer may mean a child. And, the person in charge of protection may mean a legal representative under the Civil Act. For example, in the case of a minor, the custodial parent may be the guardian. In addition, the related institution may refer to a protective institution related to the abuse of minors.

1 shows a smart watch 1 according to an embodiment of the present invention. Figure 1 (a) shows the front of the smart watch (1), Figure 1 (b) shows the rear of the smart watch (1). The rear surface of the smart watch 1 may refer to a part in contact with the wrist when a user or a wearer wears the smart watch 1 on the wrist.

Referring to Figure 1 (a), the smart watch (1) is provided on the back of the body portion 10 including the display 15 on the front, the body portion 10 to measure the heart rate of the user It includes a heartbeat sensor unit 191, and a control unit 149 provided inside the body unit 10 to control the display 15 and the heartbeat sensor unit 191 and communicate with the outside. In addition, when the value obtained by converting the heart rate of the user measured for a preset heart rate time through the heart rate sensor unit 191 into heart rates per minute is outside a predetermined heart rate allowable range, the A warning message can be sent to the user's protection manager (2) or the relevant agency (3).

A typical wrist watch may include a body that displays time and a belt to be worn. Similarly, the smart watch 1 is connected to the body portion 10 constituting the main body and the body portion 10 so as to wrap the wrist so that the body portion 10 can be positioned on the user's wrist. It may include a worn part 50 in the form of a belt or band provided.

The body portion 10 includes a display 15 provided on the front side, a front case 11 coupled to the display 15 , and a rear case coupled to the front case 11 in the opposite direction to the display 15 . (13) may be included.

The display 15 may include a time display unit 151 for displaying time and a heart rate display unit 152 for displaying the user's heart rate. The display 15 may be a kind of touch display. Accordingly, the display 15 may display other information in addition to the time display unit 151 and the heartbeat display unit 152 . For example, temperature and humidity may be included in the display 15 , when child abuse is suspected, or when the smart watch 1 is unintentionally separated from the user's wrist, or when the smart watch 1 is When wearing is released, a warning message may be displayed through the display 15 .

A control unit 149 (refer to FIG. 2 ) for input/output through the display 15, various sensor units to be described later, and communication with the outside may be located inside the body unit 10 . The control unit 149 may communicate with the outside using Wi-Fi or Bluetooth. Through this, when it is determined that the user is being abused, the control unit 149 may notify the user in charge of protection 2 of the smart watch 1 or a related organization 3 of a warning.

Referring to FIG. 4 , a warning may be notified in real time to the information communication terminal of the person in charge of protection 2 , such as a smart phone, or the monitoring system of the related organization 3 .

The body part 10 may include a coupling part 12 for connecting the wearing part 50 and the body part 10 . The coupling part 12 may include a first coupling member 121 and a second coupling member 122 positioned in opposite directions in the body part 10 to be coupled to the wearing part 50, respectively. .

The wearing part 50 may include a buckle part 53 and a belt loop part 55 for wrapping and coupling the user's wrist. In addition, it may include a plurality of hanging holes 57 for passing through the wearing part (50) to be coupled to the belt loop part (55). The belt loop part 55 may be coupled to any one of the plurality of hanging holes 57 . This is to adjust the length of the wearing part 50 that wraps around the user's wrist according to the thickness of the user's wrist.

In addition, when the belt loop part 55 is coupled to the plurality of hanging holes 57 , one end of the wearing part 50 may be inserted into the buckle part 53 .

Referring to FIG. 1B , since the rear case 13 is a part in contact with the user's wrist, a sensor unit for detecting the user's biometric information may be located therein. That is, the smart watch 1 has a heartbeat sensor unit 191 on the rear case 13 for measuring the user's heartbeat, and an acoustic sensor for detecting a sound coming back after oscillating a frequency of the user's MHz band. The unit 194, the acceleration sensor unit 192 or gyroscope for detecting a sudden movement of the user, and the electrocardiogram sensor unit 196 for measuring the user's electrocardiogram may be located. In particular, the heartbeat sensor unit 191 , the acoustic sensor unit 194 , and the electrocardiogram sensor unit 196 may have sensing regions exposed to the outside of the rear case 13 in order to come into contact with the user's skin.

1(b) shows that the heartbeat sensor unit 191 is located in the center, but this is only an example and may be located in other parts. The same is true for other sensor units.

The pulse sensor used in smart devices has less energy than X-rays, so safe green light, red light, and infrared light are used. Just as X-rays are applied to the body from one side and read with a photosensitive plate, the pulse sensor consists of a light emitting part and a reading part.

An embodiment of the heart rate sensor unit 191 is to measure the heart rate of the user using light (light). Specifically, the heartbeat sensor unit 191 uses that light (green light, red light, infrared light) enters the skin, some is reflected, and some reaches the blood vessel. The light that reaches the blood vessel can be absorbed and reflected by the color of hemoglobin in the blood. This is how the light changed due to hemoglobin is measured. By analyzing this measured value, it can be seen that the blood vessels expand and contract according to the heartbeat, so it can be used to calculate the heart rate.

An embodiment of the acoustic sensor unit 194 may simply measure the user's heartbeat or breathing sound to determine whether there is an abnormality, but after actively emitting sound waves, it checks whether the return sound waves are deformed or not You can also check for fractures.

That is, the acoustic sensor unit 194 uses a 60 Hz (hertz) notch filter to remove attention noise, power supply noise, and high-frequency noise, and removes the high-frequency signal using a wavelet, which shows the characteristics of the heart sound. The signal area can be detected. Heart sounds, which are heart sounds, can be divided into four main types. The first heart sound is a sound generated when the mitral and tricuspid valves are closed, and is slightly lower and longer than the second heart sound. The mitral valve closure is slightly faster than the tricuspid valve closure, but the gap is narrow and usually audible as a single sound. The second heart sound is generated when the aortic and pulmonary valves are occluded. Normally, the aortic valve occlusion sound precedes the pulmonary valve closure sound. The third heart sound occurs when blood suddenly enters the ventricle and the ventricular wall expands rapidly. Therefore, the size of the third heart sound depends on the pre-load, the pressure of the atrium, and the elasticity of the myocardium. Adolescents can auscultate normally without heart disease, but in adults, pathological findings suggest ventricular failure. The fourth heart sound is caused by an increase in ventricular pressure due to the contraction of the atrium at the end of the diastolic period, and is auscultated just before the first heart sound with a very low sound. Auscultation is performed when the ventricular end-diastolic pressure is elevated or the ventricular dilatability is decreased, such as hypertension or aortic stenosis.

In general, heart sounds span from 10 Hz to 250 Hz. In particular, the first heart sound and the second heart sound are important. The first heart sound can be measured between 91 Hz and 179 Hz, and in the case of the second heart sound, there may be signals reaching up to 200 Hz. Therefore, using these characteristics of the heart sound, the controller 149 can determine whether or not abuse is caused by comparing the heart sound normally sensed with the abnormal heart sound sound detected during abuse.

In the case of respiration, the high-frequency component is distributed up to 2 kHz, and when measured from a distance from the lungs, such as a wrist watch, the respiration sound is absorbed by the lung tissue, so the signal may tend to attenuate as the frequency increases. In addition, distinction from heart sounds and other noises is essential. Recently, due to the development of digital signal processing technology, if the sound is amplified and noise is removed, it is possible to distinguish the heart sound within 250 Hz and the breathing sound at 100~1500 Hz.

Accordingly, the acoustic sensor unit 194 simultaneously detects a heart sound and a breathing sound, and can be used as an auxiliary indicator for child abuse.

That is, the control unit 149 can determine whether the child is abused when it is outside the preset allowable heart rate range through the heart rate sensor unit 191 . That is, one of the main conditions for determining child abuse is whether the heart rate is outside the allowable range. Preferably, the allowable heart rate may be greater than 50 beats per minute and less than 130 beats per minute.

The heartbeat sensor unit 191 measures the user's heart rate during a preset heartbeat time, but the heartbeat time may not necessarily be 1 minute. Therefore, the control unit 149 converts this to heartbeats per minute, and if the converted value satisfies the allowable heartbeat range, it is determined as normal, and if it is out of the heartbeat range, the user is abused It can be judged that there is

However, since the heart rate of the user may increase even when simply playing or running, in order to supplement this, the heart sound and breathing sound through the acoustic sensor unit 194 are also detected to be used as another condition for determining whether or not the child is abused. there is.

For example, even if the heart rate is 120 beats per minute, if the breathing sound and the heart sound are abnormal, it can be determined that there is a problem.

Also, the acoustic sensor unit 194 may determine whether a bone is fractured by oscillating ultrasonic waves in a megahertz (MHz) region and then detecting the returned ultrasonic waves. This takes advantage of the fact that, unlike a normal structure, when a crack or a fault occurs in the structure, the frequency or waveform of the returned ultrasonic wave changes. By using this, even when a user is assaulted and a micro fracture such as incontinence occurs in the bone, it can be detected immediately.

That is, when the change in the frequency and waveform of the acoustic wave sensed through the control unit 149 and the acoustic sensor unit 194 is out of the allowable values, it is determined that a fracture has occurred in the user's bone and the person in charge of protection (2) or A warning message may be sent to the relevant authority 3 .

Accordingly, the control unit 149 detects the user's biometric information, determines whether the child abuse condition is satisfied, and then determines that child abuse is child abuse can be notified in real time.

The child abuse condition may include heart rate as a main condition and heart sound and breathing sound as auxiliary conditions. In addition, the smart watch 1 detects a sudden change in the smart watch 1 through the acceleration sensor unit 192 built into the body unit 10 and uses it as an additional condition for whether or not child abuse is present. there is. This is because, unlike usual, a sudden change in the acceleration of the smart watch 1 may appear when a child runs or runs away. The acceleration sensor unit 192 may be implemented as a gyroscope in addition to the 3-axis acceleration sensor.

On the other hand, when the heart rate is not measured through the heart rate sensor unit 191, it may be determined that the wearing is released. This may be determined as whether the user has released the wear or that another third party has forcibly removed the wear of the user. Therefore, rather than notifying it every time, it can be programmed to notify when a predetermined number of release times is reached.

That is, the control unit 149 may determine whether or not abuse is based on the accumulated number of unlocks of the smart watch 1 . That is, if the heart rate through the heart rate sensor unit 191 is not detected, the control unit 149 increases the number of accumulated release times by one, compares it with a preset reference value, and protects the user when the reference value is reached. A warning message can be sent to the person in charge or the relevant agency.

Even if the accumulated release count is not reached, the controller 149 may display a warning on the display when the accumulated release count is less than the reference value in order to remind the surrounding attention.

Preferably, the reference value may be set to 5 times. Accordingly, when the cumulative number of release times reaches 5, the control unit 149 may automatically notify the user in charge of protection (2) or the relevant agency (3) of a warning. In the future, only when the person in charge of protection 2 permits the reset, the control unit 149 will be able to count the number of times of accumulated release again after reset.

In addition, the smart watch 1 may further include an electrocardiogram sensor unit 196 provided on the rear surface of the body unit 10 to measure the user's electrocardiogram. This may be implemented using a photoplethysmographic sensor.

Unlike FIG. 1B , the heartbeat sensor unit 191 , the acceleration sensor unit 192 , the electrocardiogram sensor unit 196 and the acoustic sensor unit 194 are located in different places in the rear case 13 . may be located.

FIG. 2 schematically illustrates the control unit 149 , the charging unit 131 , the battery unit 141 , the vibrating unit 142 , and the battery unit 141 positioned inside the body unit 10 . The smart watch 1 may include a control unit 149 for controlling the display 15 and the sensing unit 19 including the various sensor units. The control unit 149 may be provided inside the body unit 10 . In addition, the smart watch 1 may further include a battery unit 141 for supplying power. The smart watch 1 may further include a charging unit 131 for supplying power to the battery unit 141 using an electromagnetic induction phenomenon. That is, the smart watch 1 is capable of wireless charging.

In addition, the smart watch 1 may further include a vibrating unit 142 including a vibrator for generating vibration. This is to use vibration as well as sound when it is necessary to alert or notify the wearer.

The charging part 131 may be made of a metal material.

The battery unit 141 may be provided in a shooting shape, but may also be provided in a circular shape or a cylindrical shape. Also, the body portion 10 is not limited to a circular shape, and may be a rectangular shape with rounded corners.

Referring to FIG. 3 , the smart watch 1 may be connected to other devices by utilizing the information communication network 9 . In particular, when it is determined that abuse has occurred to the user, the smart watch 1 notifies the user in charge of protection 2 or the related organization 3 of the abuse using the information communication network 9. can

Through this, the person in charge of protection (2) or the relevant agency (3) will be able to respond immediately to the abuse. In addition, the smart watch 1 may transmit the user's biometric information, for example, heart rate, heart sound, and breathing sound to the learning server 7 . By utilizing the user's biometric information, the learning server 7 will be able to apply a customized abuse determination condition to the user through deep learning.

For example, the allowable heart rate range may be changed from more than 50 beats per minute to less than 130 beats per minute, but from 57 to 138 beats per minute through deep learning.

4 shows an example of a control method for determining whether or not child abuse by using the smart watch.

When the user wears the control method of the present invention, the smart watch proceeds with the step of confirming the user's biometric information (S100). This is a step that is repeatedly performed after wearing.

Specifically, the step of confirming the user's biometric information (S100) may include the step of confirming the user's heart rate per minute through the heart rate sensor unit 191. In addition, the step of confirming the user's biometric information (S100) may further include the step of additionally confirming the user's biosignal through the acoustic sensor unit 194. The user's bio-signal may refer to a heart sound that is the user's heart sound, a hoarse sound generated during respiration, or an ultrasonic wave oscillated by the acoustic sensor unit 194 and returned.

In addition, the step of confirming the user's biometric information (S100) to determine whether or not child abuse is the step of additionally confirming the user's biometric information through the acceleration sensor unit 192 and the electrocardiogram sensor unit 196 may include

If the heart rate of the user is not detected through the heart rate sensor unit 191, the control method of the present invention may determine that the user's wearing of the smart watch is released (S300). In addition, this may be additionally confirmed by utilizing the fact that no heart sound or breathing sound is detected through the acoustic sensor unit 194 .

When it is determined that the wearing of the smart watch 1 is released, the control method of the present invention may determine whether the accumulated number of times of release is equal to or greater than a predetermined reference value (S500). The reference value may be preferably set to 5 times. This is because if the threshold is low, unnecessary warnings may be sent, and if the threshold is too high, it is possible that the abuser may not be aware of it.

When the accumulated number of release times is equal to or greater than the reference value (S500), the control method of the present invention may notify the user in charge of protection or a related organization (S900).

If the number of times of cumulative release is less than the reference value (S500), the control method of the present invention displays a release warning on the display (S200), increases the number of times of cumulative release by one (S400), and then returns the user's biometric information The step of repeatedly confirming (S100) may proceed.

When wearing off is not detected in the smart watch 1, the control method of the present invention may determine whether or not child abuse is performed through the user's biometric information (S700). The child abuse condition may be determined based on whether or not the heart rate per minute of the user satisfies a preset allowable heart rate range.

For example, the heart rate measured through the heart rate sensor unit 191 for a preset heart rate time may be converted into heart rates per minute, and compared whether the converted heart rate satisfies the heart rate allowable range. The allowable heart rate may be set to more than 50 beats per minute and less than 130 beats per minute. Accordingly, in the control method of the present invention, when the heart rate is 50 beats per minute or less or 130 beats per minute or more, the user's protection officer 2 or the related organization 3 may be notified (S900).

That is, as shown in FIG. 3, custom settings can be made according to the user's individual biometric information using deep learning through biometric information. (2) or the relevant agency (3) may be notified immediately.
