Description

{A MEHTHOD OF MEASURING A RESTING HEART RATE}

The present invention relates to a method for measuring resting heart rate with high accuracy.

As the quality of life increases, interest in health is also increasing.

In particular, heart beat is a very important health indicator. The heartbeat depends on the behavior of the individual in daily life, whether it is walking, running or not. The heartbeat also varies daily for the same person depending on the person's health condition.

Since the heart rate varies according to various situations, it is difficult to set the heart rate fluctuating from time to time as a reference heart rate to check an individual's health.

Therefore, the setting of the reference heartbeat is very important in order to accurately check the individual's health.

Recently, a resting heart rate has been suggested as a reference heartbeat.

A resting heartbeat is a heartbeat measured in a special situation, not moving and psychologically calm. Therefore, the individual's health check can be accurately performed through the relaxation heartbeat.

However, the resting heartbeat is measured in a special situation, and a device or a method for measuring the resting heartbeat with high accuracy without error is not yet presented while grasping such a special situation.

The present invention is directed to solving the above-mentioned problems and other problems.

Another object of the present invention is to provide a method for measuring a resting heart rate by measuring a resting heart rate by judging a situation where a resting heart rate can be measured by itself.

Another object of the present invention is to provide a method for measuring resting heart rate with high accuracy.

 According to an aspect of the present invention, there is provided a method for measuring a resting heart rate in a relaxation heart rate measuring apparatus including a heart rate sensor, an acceleration sensor, and a display unit. The method of measuring resting heart rate comprises: inputting a heart rate of a user measured from the heart rate sensor; Inputting motion information of the user detected by the acceleration sensor; Determining whether at least one of the measured heart rate and the detected motion information satisfies a condition for measuring a resting heart rate; And determining the measured heartbeat to be a resting heartbeat if at least one of the measured heartbeat and the detected motion information satisfies the condition for the relaxation heartbeat measurement.

The effect of the resting heart rate measuring method according to the present invention is as follows.

According to at least one of the embodiments of the present invention, when a state of motion after sleeping or everyday life is detected, the heart rate measuring device itself measures the heart rate, determines the measured heart rate as a rest heart rate and sets it as a reference heart rate . In particular, the reference heart rate set in everyday life can be obtained by judging whether the average value of the heart rate fluctuation, the degree of heart rate variability, the degree of opening between the maximum peak heart rate and the minimum peak heart rate, and the average value of the heart rate peak are located between the minimum heart rate and the maximum heart rate have. Therefore, it is possible to measure the heartbeat with high accuracy without error by eliminating the error in the heartbeat measurement, thereby improving the reliability of the user's product.

According to at least one of the embodiments of the present invention, since the user can measure the resting heartbeat automatically in a situation satisfying the heartbeat measuring condition, there is an advantage that the user does not need to separately operate for measuring the resting heartbeat.

The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role. In the following description of the embodiments of the present invention, a detailed description of related arts will be omitted when it is determined that the gist of the embodiments disclosed herein may be blurred. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. , ≪ / RTI > equivalents, and alternatives.

Terms including ordinals, such as first, second, etc., may be used to describe various elements, but the elements are not limited to these terms. The terms are used only for the purpose of distinguishing one component from another.

It is to be understood that when an element is referred to as being "connected" or "connected" to another element, it may be directly connected or connected to the other element, . On the other hand, when an element is referred to as being "directly connected" or "directly connected" to another element, it should be understood that there are no other elements in between.

The singular expressions include plural expressions unless the context clearly dictates otherwise.

In the present application, the terms "comprises", "having", and the like are used to specify that a feature, a number, a step, an operation, an element, a component, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

The resting heart rate measuring device of the present invention can be implemented as a wearable device. A wearable device includes a watch-type mobile terminal, a glass-type mobile terminal, a neckband-type mobile terminal, a bracelet-type mobile terminal, and a bracelet-type mobile terminal.

The wearable device equipped with the device for measuring resting heart rate of the present invention is worn on the wearer's wrist and the rest heart rate can be measured.

Alternatively, the resting heart rate measuring device of the present invention may be implemented separately from the wearable device.

The resting heart rate may be different depending on sex or health condition, as shown in Fig.

As shown in Fig. 1A, in the case of male, the resting heartbeat can be smaller as a healthy person. For example, if the age is between 18 and 25, the person with averaged health has a resting heart rate of 70 to 73, while a poor person with a resting heart rate is above 82 and athlete has a rest The heart rate may be between 49 and 55.

Likewise, as shown in FIG. 1B, in the case of a woman, a healthy person may have a smaller resting heartbeat.

In addition, men have lower resting heart rate than women in the same conditions.

The relaxation heartbeat can be used as follows.

First, resting heartbeats can be used as a basis for individual health indicators.

For example, if the measurement of the resting heart rate is accurate without error, the resting heart rate can be measured by the resting heart rate measuring device if it is loaded on the resting heart rate measuring condition every day or from time to time. The measured resting heartbeats are stored in the database, and various key indicators can be calculated by the Big Data algorithm. For example, if the user's normal resting heart rate is 60 and the measured resting heart rate is more than 100, it gives a danger signal to the user's health and the user can visit the hospital promptly.

Second, resting heartbeat can be used as a reference heartbeat when measuring physical fitness.

For example, when the user wakes up one morning in the morning, if the resting heartbeat is measured to be, for example, 5 to 10 times higher than a normal resting heartbeat, the user may experience a cold, stress, or tired state, It means that the health condition is not good, so the user can take a rest without exercising on the same day.

As another example, if the user's heart rate measured in the morning is set to be the reference heart rate, and the measured resting heart rate is higher than the reference heart rate by 5 or more, the user's health is not good It can mean.

Third, a resting heartbeat can alert the user to health hazards during exercise or at normal times, giving an alarm or alert.

For example, when the reference heart rate is set as described above, an alarm may be given to the user when the rest heart rate is higher than the reference heart rate by, for example, 5 or more on a particular day. Alternatively, when the resting heart rate is higher than a reference heart rate, for example 20 to 30 or more, on a particular day, a risk warning is given to the user while a danger warning message is immediately transmitted to the relevant public agency such as a fire department or emergency control sensor .

For example, even if the reference heartbeat is not set, if the resting heartbeat is overly high, such as 100 or more, on a particular day, a message related to the warning may be immediately transmitted to the relevant public agency, such as a fire department or emergency control sensor.

Hereinafter, for convenience of description, a resting heart rate measuring apparatus is described as being implemented in a watch-type mobile terminal (100 of FIG. 2), but the resting heart rate measuring apparatus of the present invention may be implemented by other mobile terminals .

According to the present invention, when only the watch-type mobile terminal 100 is worn on the user's wrist, the watch-type mobile terminal 100 itself can not measure the resting heart rate measurement condition If a situation is found that meets the heart rate measurement conditions, it can automatically measure the heart rate and inform the user of the result. A method of informing a user may be a method of displaying a message on a voice alert or a display unit.

The input unit 120 includes a camera 121 or an image input unit for inputting a video signal, a microphone 122 for inputting an audio signal, an audio input unit, a user input unit 123 for receiving information from a user A touch key, a mechanical key, and the like). The voice data or image data collected by the input unit 120 may be analyzed and processed by a user's control command.

The camera 121 processes image frames such as still images or moving images obtained by the image sensor in the video communication mode or the photographing mode. The processed image frame may be displayed on the display unit 151 or stored in the memory 170. [

The microphone 122 processes the external acoustic signal into electrical voice data. The processed voice data can be utilized variously according to functions (or application programs being executed) being performed in the watch-type mobile terminal 100.

The user input unit 123 is for receiving information from the user. When information is inputted through the user input unit 123, the controller 180 controls the operation of the watch-type mobile terminal 100 to correspond to the input information. can do. The user input unit 123 may include a mechanical input unit (or a mechanical key such as a button located on the front, rear or side of the watch-type mobile terminal 100, a dome switch, A jog wheel, a jog switch, etc.) and a touch type input means.

The sensing unit 140 may include at least one sensor for sensing at least one of the information in the watch-type mobile terminal 100, the surrounding information surrounding the watch-type mobile terminal 100, and the user information. For example, the sensing unit 140 may include a proximity sensor, an illumination sensor, a touch sensor, a heart rate sensor 141, an acceleration sensor 142, a magnetic sensor a G-sensor, a gyroscope sensor 143, a wear sensor 144, a motion sensor, an RGB sensor, an infrared sensor (an infrared sensor), a fingerprint sensor Such as a finger scan sensor, an ultrasonic sensor, an optical sensor (e.g., a camera 121), a microphone (see microphone 122), a battery gauge, (E.g., a barometer, a hygrometer, a thermometer, a radiation detection sensor, a heat detection sensor, a gas detection sensor, etc.), a chemical sensor (e.g., an electronic nose, a healthcare sensor, a biometric sensor, etc.) . Meanwhile, the watch-type mobile terminal 100 disclosed in the present specification can combine and utilize information sensed by at least two of the sensors.

The heart rate sensor 141 senses the shaking of the blood vessel as an electric signal, and the heart rate can be calculated from the sensed electric signal.

There are many blood vessels in the user's finger. A blood vessel is a passage through which blood flows, and blood flows to all the blood vessels of the body by the pumping of the heart. Because the blood flows into the blood vessels by the pumping of the heart, the blood vessels can swirl like wave-like waves.

In the interval between pumping in the heart, the blood vessels may have small width irregularities. On the other hand, when pumping in the heart, the blood vessels can have large irregularities.

Therefore, the reflection amount and the reflection angle of light are different due to the small width irregularities generated in the interval between the pump materials and the large irregularities generated in the pump. The amount of light received by the light sensing unit varies depending on the reflection amount and the reflection angle, and electric signals of different sizes can be output by the different amounts of light.

For this, the heartbeat sensor 141 may include a light emitting portion and a light receiving portion. The light emitting portion may include a light emitting element, and the light receiving portion may include a light receiving element. The degree to which the light emitted from the light emitting portion is reflected by the width of the irregularities of the blood vessel is different. The reflected light that is reflected differently in this manner is detected by the light-receiving unit, and the reflected light thus detected can be converted into an electric signal. That is, the heartbeat sensor 141 can generate an electric signal corresponding to the heartbeat of the user. The control unit 180 can sense or measure the heartbeat of the user based on the electrical signal.

The acceleration sensor 142 detects a speed increase / decrease in one direction, and the gyroscope sensor 143 detects an angle of the object with respect to one axis. By using the acceleration sensor 142 and the gyroscope sensor 143, the gesture of the watch-type mobile terminal 100 can be recognized, and various operations can be performed according to the gesture thus recognized. I will explain.

The wear detection sensor 144 is for detecting wear of the watch-type mobile terminal 100 and may be disposed on the rear surface of the main body 201 (see FIG. 32A). The wear detection sensor 144 may include a light emitting portion and a light receiving portion, and may be a heartbeat sensor 141, but the present invention is not limited thereto.

The wear detection sensor 144 can be always operated.

When the watch-type mobile terminal 100 is worn on the user's wrist, the light emitted from the light emitting portion of the wear detection sensor 144 is reflected by the wrist of the user, and such reflected light can be detected by the light receiving portion. It can be seen that the watch-type mobile terminal 100 is worn on the user's wrist based on the reflected light thus detected.

If the watch-type mobile terminal 100 is detached from the user's wrist, the light emitted from the light emitting portion of the wear detection sensor 144 is no longer reflected by the wrist of the user, so that no light is reflected by the light receiving portion . Thus, it can be understood that the watch-type mobile terminal 100 is detached from the user's wrist based on the fact that the reflected light is not blurred.

For example, the heartbeat sensor 141 may be set to operate only when the watch-type mobile terminal 100 is worn on the wearer's wrist. The power consumption of the watch-type mobile terminal 100 can be reduced by allowing the heartbeat sensor 141 to be turned on only under certain conditions.

The output unit 150 includes at least one of a display unit 151, an acoustic output unit 152, a haptic tip module 153, and a light output unit 154 to generate an output related to visual, auditory, can do. The display unit 151 may have a mutual layer structure with the touch sensor or may be integrally formed to realize a touch screen. The touch screen functions as a user input unit 123 for providing an input interface between a watch-type mobile terminal 100 and a user, and provides an output interface between the watch-type mobile terminal 100 and a user .

The display unit 151 displays (outputs) information processed by the watch-type mobile terminal 100. For example, the display unit 151 displays execution screen information of an application program driven by the watch-type mobile terminal 100, UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information can do.

The sound output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The audio output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated in the haptic module 153 can be controlled by the setting of the user's selection or control unit 180.

The light output unit 154 outputs a signal for notifying the occurrence of an event using the light of the light source of the watch-type mobile terminal 100. Examples of events that occur in the watch-type mobile terminal 100 include message reception, call signal reception, missed call, alarm, schedule notification, e-mail reception, information reception through an application, and the like.

The interface unit 160 serves as a channel for connecting various types of external devices connected to the watch-type mobile terminal 100. The interface unit 160 is connected to a device having a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, And may include at least one of a port, an audio I / O port, a video I / O port, and an earphone port. In the watch-type mobile terminal 100, corresponding to an external device being connected to the interface unit 160, it is possible to perform appropriate control related to the connected external device.

The memory 170 stores data supporting various functions of the watch-type mobile terminal 100. The memory 170 may store a plurality of application programs or applications driven by the watch-type mobile terminal 100, data for operation of the watch-type mobile terminal 100, and commands . At least some of these applications may be downloaded from an external server via wireless communication. At least some of these application programs may be stored in the watch-type mobile terminal 100 from the time of departure for basic functions (e.g., phone call incoming, outgoing, message receiving, and origination functions) of the watch- Lt; / RTI > Meanwhile, the application program is stored in the memory 170, installed on the watch-type mobile terminal 100, and executed by the control unit 180 to perform the operation (or function) of the watch-type mobile terminal 100 Can be driven.

The control unit 180 controls the overall operation of the watch-type mobile terminal 100, in addition to the operations associated with the application program. The control unit 180 may process or process signals, data, information, and the like input or output through the above-mentioned components, or may drive an application program stored in the memory 170 to provide or process appropriate information or functions to the user.

[

FIG. 3A is a perspective view showing an example of a watch-type mobile terminal according to the present invention, and FIG. 3B is a perspective view showing another example of a watch-type mobile terminal related to the present invention.

3A and 3B, the functions of the remaining components are the same except that the shape of the touch screen 251 of the watch-type mobile terminal 100 is different. That is, the touch screen 251 of the watch-type mobile terminal 100 shown in FIG. 3A has a circular shape, whereas the touch screen 251 of the watch-type mobile terminal 100 shown in FIG. Shape. The touch screen 251 shown in FIG. 3A may have an elliptical shape instead of a circular shape, but the present invention is not limited thereto. The touch screen 251 shown in FIG. 3B may have a pentagonal or hexagonal shape instead of a rectangular shape, but the present invention is not limited thereto.

The shape of the touch screen 251 of the present invention may be any shape that can give a visually good image to the user and help the user to operate the touch screen 251.

3A and 3B, a watch-type mobile terminal 100 includes a main body 201 having a touch screen 251 and a band 202 connected to the main body 201 and configured to be worn on the wrist .

The main body 201 includes a case that forms an appearance. As shown, the case may include a first case 201a and a second case 201b that provide an internal space for accommodating various electronic components. However, the present invention is not limited thereto, and one case may be configured to provide the internal space.

A touch screen 251 is disposed on the front surface of the main body 201 to output information. A touch sensor is provided on the touch screen 251 to receive information. The window 251a of the touch screen 251 may be mounted on the first case 201a to form a front surface of the terminal body together with the first case 201a.

The main body 201 may include an audio output unit 252, a camera 221, a microphone 222, a user input unit 223, and the like.

The touch screen 251 is the display unit 151 of FIG. 2, the sound output unit 252 is the sound output unit 152 of FIG. 2, the camera 221 is the camera 121 of FIG. 2, 222 may be the microphone 122 of FIG.

The band 202 is worn on the wrist so as to surround the wrist, and may be formed of a flexible material for easy wearing. As an example, the band 202 may be formed of leather, rubber, silicone, synthetic resin, metal having elasticity, and the like. In addition, the band 202 may be detachably attached to the main body 201, and may be configured to be replaceable by various types of bands according to the user's preference.

Hereinafter, a method of measuring a heart rate using the watch-type mobile terminal 100 will be described.

Although not shown in FIGS. 4 and 6, the heartbeat sensor 141 can be operated only when the watch-type mobile terminal 100 is worn on the wearer's wrist. Thus, the heartbeat sensor 141 is not operated at all times, and the power consumption can be reduced.

When the watch-type mobile terminal 100 is worn on the wearer's wrist, the heartbeat sensor 141 (regardless of whether it is before, during, or after the sleep), unless the watch-type mobile terminal 100 is detached from the wrist of the user Can be operated.

When the watch-type mobile terminal 100 is detached from the user's wrist, the operation of the heartbeat sensor 141 can be stopped even if the heartbeat sensor 141 is in operation.

4 is a flowchart illustrating a method for measuring a resting heart rate according to a first embodiment of the present invention.

The resting heart rate measuring method shown in FIG. 4 can be measured after the user wakes up from the surface of the water.

Referring to FIGS. 2 and 4, the minimum heart rate and the maximum heart rate can be set (S311).

The minimum heart rate can be set to 30. A minimum heart rate of 30 may be a smaller value than the least heart rate athlete. Typically, as shown in FIG. 1A, the heart rate of a male athlete between 18 and 25 may be 49 to 55.

The maximum heart rate can be obtained by subtracting age from 220 and multiplying by 0.8. For example, the maximum heart rate of a person aged 46 may be (220-46) * 0.8 = 139.2. As such, the maximum heart rate may vary with age.

The control unit 180 can confirm whether the user is sleeping (S313).

The user can be grasped by the heartbeat sensor 141 and the acceleration sensor 142 while the user is sleeping. The heartbeat sensed by the heartbeat sensor 141 may vary according to a person's behavior. In particular, heart rate can vary during sleep and when awake.

If the heart rate is measured in advance, the heart rate measured from the heart rate sensor 141 is compared with the predetermined heart rate. If the measured heart rate matches the predetermined heart rate, the user may be determined to be in the sleep state.

The acceleration sensor 142 can sense the motion of the user. The user's movements are different while sleeping and awake. When the user is awake, even if the user is still there, there is a movement of the user that the user can not detect. In addition, when the user is awake, they usually move.

It can be grasped that the user is sleeping based on the movement of the user calculated based on the acceleration signal detected from the acceleration sensor 142. [

When it is determined that both the heartbeat measured by the heartbeat sensor 141 and the motion detected by the acceleration sensor 142 are in the user sleep state in preparation for the possibility of detection failure of the heartbeat sensor 141 or the acceleration sensor 142, The user may be judged to be in the sleep state but may be individually used to determine whether the heartbeat measured by the heartbeat sensor 141 and the motion detected by the acceleration sensor 142 are at the user's sleeping position.

On the other hand, the heart rate can be less than 30 when the user is sleeping. Such heart rate is smaller than the minimum heart rate set in S311.

If the heartbeat from the user detected by the heartbeat sensor 141 is less than 30, it may be determined that the user is sleeping.

If it is determined that the user is not in the sleep state, the process moves to S323 of FIG. 6 and the heart rate can be measured in a predetermined time unit, for example, in units of one minute.

The control unit 180 can confirm whether the user has awakened from the water surface (S315).

Whether or not the user has awakened from the surface of the water can be determined based on the heartbeat measured by the heartbeat sensor 141 and / or the motion detected by the acceleration sensor 142, similarly to the above description.

When the user wakes up, the control unit 180 controls the heartbeat sensor 141 to measure the heartbeat of the user (S317). At this time, the heartbeat can be measured for a predetermined time, for example, one minute, but it is not limited thereto.

As shown in Fig. 5, the diastolic BP is different between when in the sleep and before and after the sleep. During sleep, diastolic blood pressure is significantly lower than before and after sleep.

When diastolic blood pressure wakes up after sleep, the heart rate is measured.

At step S317, the user may remain awake during the measurement of the heart rate. In other words, if the user starts to move as soon as he wakes up, the heartbeat may change rapidly.

Whether or not the user has moved after sleeping can be determined from the motion detected from the acceleration sensor 142 or the heartbeat measured from the heartbeat sensor 141.

The controller 180 may measure the heart rate of the user when the user does not move for a predetermined time after sleeping. Here, the predetermined time may be 30 seconds to 3 minutes, but the present invention is not limited thereto.

The measured heart rate can be set to the minimum heart rate when the user is not moving for a certain period of time. In addition, the measured heartbeat is determined as a resting heartbeat, and the determined resting heartbeat may be set as a reference heartbeat for a user's health check.

The user can check his or her health through changes in the resting heart rate measured daily or intermittently after taking a good night's sleep.

For example, if a resting heart rate measured at a normal time is 60, and a resting heart rate measured after a certain day's sleep is 90, the user is not in good health. If you exercise in this situation, you may be at risk for a heart attack.

For example, if the resting heartbeat is normal and the resting heartbeat measured after the sleep of a certain day comes to a heartbeat approaching the predetermined maximum heartbeat considering the age of the user, the user's health is not very good. An emergency risk alert message may be sent to the relevant public authority, such as a fire station.

Elderly elderly people often die during sleep. In this case, when the watch-type mobile terminal 100 according to the present invention is worn on the wrist of the elderly, the normal heartbeat is measured to be excessively higher than the resting heartbeat before or after the sleeping Immediately, an urgent risk alert message is sent to the relevant public agency, enabling urgent emergency measures for the elderly, so that valuable life can be saved in time. Here, the normal heartbeat may be a state in which the user is moving and the heartbeat is enlarged according to the movement, and is not a resting heartbeat.

FIG. 6 is a flowchart illustrating a method for measuring a resting heart rate according to a second embodiment of the present invention.

The resting heart rate measuring method shown in FIG. 6 can be applied to the user during daily life.

As described above, since there is no movement in order to measure the resting heart rate, resting heart rate may not be measured in everyday life.

Nevertheless, the specific conditions such as the resting heart rate measurement condition, 1) the acceleration variable is below the first threshold value, 2) the heart rate variability is below the second threshold value, and 3) the difference between the maximum value and the minimum value of the heart rate peaks is 3 (4) the mean heart rate peak values can be measured between the minimum heart rate and the maximum heart rate.

The degree of heart rate variability may mean the degree of variation of the heart rate measured from the heart rate sensor 141. In addition, the degree of variable acceleration may mean a variable degree of the acceleration detected from the acceleration sensor 142. [

For example, if you are lying still in your daily life, you may have a resting heartbeat.

For example, if sitting quietly for meditation in everyday life, a resting heartbeat can be measured.

In addition, resting heart rate can be measured in various situations even in daily life.

Referring to FIGS. 2 and 6, the minimum heart rate and the maximum heart rate can be set (S321).

The setting of the minimum heart rate and the maximum heart rate has been described in detail in S311 of FIG. 4, so that further description will be omitted.

While the user is in daily life, the watch-type mobile terminal 100 can measure the heart rate in a predetermined interval (time) (S323). For example, the predetermined interval (time) unit may be 1 minute, but this is not limitative.

For example, as shown in Fig. 7, the heart rate can be measured in units of one minute.

The control unit 180 can determine whether the degree of acceleration variation in the first section is less than or equal to the first threshold value a (S325). The first threshold value (a) may be changed by the user but is not limited thereto.

The acceleration signal can be detected by the acceleration sensor 142. The control unit 180 can calculate the degree of acceleration variation based on the detected acceleration signal.

The acceleration variable degree may be an acceleration variation amount with time.

For example, when the user does not move, the acceleration signal detected by the acceleration sensor 142 does not change with time, so that the acceleration variable degree may be zero or close to zero.

For example, when the first threshold value is set to 5 and the acceleration variable degree is 3, the acceleration variable degree is less than or equal to the first threshold value, so that the process can be shifted to S327.

For example, when the user moves, the acceleration signal detected by the acceleration sensor 142 changes with time. The larger the user's motion, the greater the variable of acceleration.

If the acceleration variable degree is equal to or greater than the first threshold value, the control unit 180 continuously checks the acceleration variable degree to check whether the acceleration variable degree falls below the first threshold value.

If the degree of acceleration variable is equal to or less than the first threshold value, the controller 180 may determine whether the heart rate variability in the first interval is equal to or less than the second threshold value b in step S327. The second threshold value b may be changed by the user but is not limited thereto.

The heartbeat signal can be detected by the heartbeat sensor 141. The controller 180 may calculate the heart rate variability based on the detected heart rate signal.

The degree of heart rate variability may be the amount of heart rate change over time.

When the user does not move, the heartbeat signal detected by the heartbeat sensor 141 does not change with time, so the heartbeat variable degree may be zero or zero.

For example, when the second threshold value is set to 10, if the degree of the heart rate variability is 7, the degree of the heart rate variability is less than or equal to the second threshold value, so that the process can be shifted to S329.

For example, when the user moves, the heartbeat signal detected by the heartbeat sensor 141 changes with time. The greater the user's motion, the greater the degree of heart rate variability.

If the heart rate variability is greater than or equal to the second threshold value, the control unit 180 continuously checks the heart rate variability to determine whether the heart rate variability falls below the second threshold value.

If the heart rate variability is below the second threshold value, the controller 180 may determine whether the difference between the minimum value min and the maximum value max of the heart rate peaks is less than or equal to the third threshold value c in step S329. The third threshold value c may be changed by the user,

As shown in FIG. 8A, heartbeat peaks may exist in the heartbeat signal. Among these heartbeat peaks, the heartbeat peaks located on the lower side are the minimum value and the heartbeat peaks located on the upper side may be the maximum value.

The difference between the minimum and maximum values of the heartbeat peaks may be the minimum and maximum values of the adjacent heartbeat peaks.

For example, as shown in Fig. 8B, the minimum value min (A) of the specific heartbeat peak and the maximum value max (A) of the specific heartbeat peak may be located adjacent to each other.

In this case, it can be determined whether the difference value C between the minimum value min (A) of the specific heartbeat peak and the maximum value max (A) of the specific heartbeat peak is smaller than the third threshold value c.

If the difference between the minimum value and the maximum value of the heartbeat peak is greater than the third threshold value, the controller 180 may remove the heartbeat peak corresponding to the minimum value and the maximum value at step S335. This removes peaks that are likely to be error-prone among the heartbeat peaks, so that accurate resting heartbeats can be measured later without error.

8A, if the difference value C between the minimum value min (A) of the specific heart rate peak and the maximum value max (A) of the specific heart rate peak is larger than the third threshold value, for example, The specific heartbeat peak corresponding to the minimum value min (A) and the specific heartbeat peak corresponding to the maximum value max (A) can be eliminated as shown in FIG. 8B.

By the operation in S329, the heartbeat peaks relatively larger or smaller than other peaks are removed, so that it is possible to precisely remove the heartbeat peaks with high possibility of error and to accurately measure the relaxation heartbeat without errors.

If the difference between the minimum value and the maximum value of the heartbeat peaks is equal to or less than the third threshold value, the controller 180 may determine whether the average value of the heartbeat peaks is between the preset minimum heartbeat and maximum heartbeat at step S331.

As shown in FIG. 9A, when the average value of the heart rate peaks deviates from the preset minimum heart rate and the maximum heart rate, the controller 180 determines that the heart rate at the current interval (for one minute) It is judged that the measurement is not performed and the flow advances to S323 to perform the heart rate measurement in the next section (for the next one minute).

As shown in FIG. 9B, when the average value of the heart rate peaks is between the preset minimum heart rate and the maximum heart rate, the controller 180 determines that the relaxation heart rate measurement is possible and determines the average value of the heart rate peaks as the rest heart rate (S333). The determined resting heartbeat may be set as a reference heartbeat for a user's health check.

On the other hand, the order of S325 to S329 can be changed. For example, it is determined whether or not the degree of variable heartbeat in step S327 is equal to or less than the second threshold value. Then, it is determined in step S325 whether the degree of acceleration variation is equal to or less than the first threshold value. max is less than or equal to the third threshold value c.

Alternatively, the operation of S329 may be performed first, and the operation may be performed in the order of S327 and S325.

In addition, the operation of any one of S325 and S327 may be omitted. For example, after the operation of any one of S325 and S327 is performed, the operation of S329 may be performed. In other words, if only one of the acceleration variable or the heart rate variability satisfies the threshold condition, it may be determined that the relaxation heart rate measurement is possible, but this is not limited.

As described above, according to the apparatus for measuring a heart rate according to the present invention, when a state of motion after sleeping or everyday life is detected, the heart rate measuring apparatus itself measures the heart rate, determines the measured heart rate as a rest heart rate, Can be set as a reference heart beat. In particular, the reference heart rate set in daily life was obtained by judging whether the average value of the heart rate fluctuation, the degree of heart rate variability, the degree of opening between the maximum peak heart rate and the minimum peak heart rate, and the average value of the heart rate peaks are located between the minimum heart rate and the maximum heart rate, By removing the error in the heart rate measurement beforehand, it is possible to measure the heart rate with high accuracy without error, thereby improving the reliability of the user's product.

FIG. 10 shows a state in which a change in the discontinuous beating heart is checked and countermeasures are taken accordingly.

10, when the watch-type mobile terminal 100 is worn on the wearer's wrist, the relaxation heartbeat is measured every day or whenever the relaxation heartbeat measurement is performed, and the measured relaxation heartbeat is displayed on the display Can be displayed on the screen. The relaxation heart rate measured daily or from time to time can be updated and displayed on the display unit.

Accordingly, the user can check his or her health condition through the change state of the resting heartbeat measured and displayed every day or from time to time.

If the resting heart rate measured at one day is excessively high compared to the resting heart rate measured at normal times, an excessively high measured resting heart rate is displayed on the display unit, while a flicker indicating the danger around the resting heart rate is displayed .

In addition, when the rest heart beat is higher than a preset rest heart beat, a message indicating the risk state of the user himself / herself can be transmitted to the related public institution without the user's operation.

In addition, as shown in FIG. 10B, the information on the countermeasure according to the excessively measured resting heartbeat is displayed on the display unit, and the user can use the self- , Emergency measures can be taken in the field.
