Description

Temperature measuring device and its control method {APPARATUS FOR MEASURING TEMPERATURE AND METHOD FOR CONTROLLING THE SAME}

The present invention relates to a temperature measuring device and a control method thereof, and more specifically, to a wrist-type temperature measuring device that is worn on the wrist to measure body temperature and a control method thereof.

As people's interest in health increases and IT technology develops day by day, healthcare devices incorporating IT technology are being developed and applied.

In addition, recently, electronic devices have been actively developed, evolving from hand-held types such as smartphones and tablet computers to wearable types that can be worn on the user's body, such as on the wrist. It is becoming.

Accordingly, healthcare devices are also being developed and provided in wearable form to increase user convenience.

One of the healthcare services provided by these wearable healthcare devices is to measure body temperature, which is the most basic biometric information used to check the subject's health status.

The temperature sensor used in healthcare devices to measure body temperature uses a contact-type temperature sensor that uses a material (e.g., mercury) whose expansion state changes depending on temperature changes, or a non-contact temperature sensor that measures heat radiated from the body temperature measurement object. .

However, in the case of such contact or non-contact temperature sensors, the measured temperature is different depending on the measurement area of the object or the body temperature of the object, resulting in many difficulties in accurately measuring body temperature.

In particular, in the case of a body temperature measuring device that uses a contact temperature sensor, the temperature rises compared to other parts due to the pressure applied to the part in contact with the contact temperature sensor to measure temperature, which causes the temperature of the contact temperature sensor itself to rise. It also rises. Therefore, an increase in temperature of the contact area and the contact temperature sensor itself interferes with accurate temperature measurement.

Additionally, in the case of a person suffering from cold hands and feet, the hand part is colder than other body parts, so when measuring the temperature of the wrist, etc., a lower temperature than the actual body temperature may be measured as body temperature.

When input from the temperature sensor unit, the second measurement temperature corresponding to the second temperature measurement signal is determined, the second correction value corresponding to the second measurement body part is read, and the second measurement temperature is corrected. The core temperature may be generated, and the generated core temperature may be output to the output unit as the body temperature of the subject.

The first body part to be measured may be the wrist.

According to this characteristic, if the temperature measured in the relevant body part of the subject is below the reference temperature, the subject may be classified as abnormal and determined to have a temperature of the relevant body part that is relatively lower than that of a normal person.

Therefore, if the subject is classified as an abnormal person, the correction value of the body temperature measured in that body part is increased compared to that of a normal person or the body temperature is measured by changing the body temperature measurement area, so the accuracy of the body temperature of the subject is lowered.

It should be understood that this does not exclude in advance the possibility of the existence or addition of elements, numbers, steps, operations, components, parts, or combinations thereof.

First, with reference to FIGS. 1 to 3, a temperature measuring device according to an embodiment of the present invention will be described.

As shown in FIG. 1, the temperature measuring device of this example is connected to the operation switch 10, the temperature sensor unit 20, the pulse wave sensor unit 30, the temperature sensor unit 20, and the pulse wave sensor unit 30. It may be provided with a temperature determination unit 40, a storage unit 50 connected to the temperature determination unit 40, and an output unit 60 connected to the temperature determination unit 40.

As shown in FIG. 2, the temperature measuring device of this example may be a wrist-type body temperature measuring device that is worn on the wrist and measures the temperature of the wrist as body temperature.

As shown in FIG. 2, since the temperature measuring device of this example is made in the form of a watch, it may be provided with a main body 110 and a wear strap 120 connected to the main body 110 for wearing on the wrist.

The operation switch 10 is a switch for operating the temperature measuring device, and the on state can be changed depending on the user's operation.

Accordingly, when the operation switch 10 is operated (i.e., turned on) by the user, the power necessary for the operation of the temperature measuring device is supplied, so that the temperature measuring device can measure the body temperature of the person being measured.

The temperature sensor unit 20 is used to measure the temperature of the subject's wrist, that is, the subject whose body temperature is measured, and can generate a temperature measurement signal corresponding to the measured temperature and output it to the temperature determination unit 40. there is.

In addition, the pulse wave sensor unit 30 is used to measure the pulse wave of a person being measured, and can generate a pulse wave signal according to the measured pulse wave and output the pulse wave signal to the temperature determination unit 40.

As an example, the pulse wave sensor unit may be equipped with a PPG sensor (photoplethysmogram sensor).

The temperature sensor unit 20 and the pulse wave sensor unit 30 may be positioned in contact with or adjacent to the subject's wrist where the body temperature is measured, which is the wearing area, and for this purpose, as shown in FIG. 2 , the temperature sensor unit 20 and the pulse wave sensor unit 30 may be mounted on the rear of the main body 110 to be exposed to the outside.

In this example, the temperature sensor unit 20 may include a contact-type temperature sensor or a non-contact-type temperature sensor.

The temperature determination unit 40 is a control module that controls the overall operation of the temperature measuring device and may be a processor.

This temperature determination unit 40 can receive a temperature measurement signal applied from the temperature sensor unit 20 and a pulse wave signal applied from the pulse wave sensor unit 30.

The temperature measured by the temperature sensor unit 20 may be the skin temperature, which is the temperature of the skin at the measurement site, and may differ from the core temperature, which is the temperature of the internal organs of the body.

Accordingly, the temperature determination unit 40 of the present example corrects the skin temperature applied from the temperature sensor unit 20 to the core temperature, so that the core temperature is finally output through the output unit 60. .

To this end, the temperature determination unit 40 may correct the skin temperature measured by the temperature sensor unit 20 to the core temperature using an internally stored core temperature correction algorithm.

As an example, the temperature determination unit 40 determines the temperature corresponding to the temperature measurement signal applied from the temperature sensor unit 20, and then determines the temperature difference between the measured area (e.g., wrist or arm) and the core (e.g., The correction temperature, which is a correction value determined by 9 degrees), can be added to the determined temperature to correct the core temperature.

The pulse wave signal may be a change in the volume of blood vessels that occurs as the heart circulates blood, converted into a waveform signal.

Therefore, the temperature determination unit 40 of this example determines the blood circulation state of the subject using the pulse wave signal applied from the pulse wave sensor unit 30, and determines the skin temperature of the subject's hand, which is farther away from the heart compared to a normal person. It can be determined whether is in a low state.

The storage unit 50 is a storage medium that stores data necessary for the operation of the temperature measuring device or data generated during the operation, and may be a memory.

In this example, the storage unit 50 may store at least one correction value for correcting the determined skin temperature to core temperature, a reference temperature, a set value for determining whether the subject suffers from cold hands and feet, etc. there is.

As already described, each correction value is for correcting the skin temperature to the core temperature and can be determined using the difference between the core temperature and the average temperature of the body part where the temperature was measured by the temperature sensor unit 20.

The reference temperature may be determined based on the average skin temperature of the first measurement site (eg, wrist) of a normal person who does not suffer from cold hands and feet. Therefore, if the skin temperature of the measured area is below the reference temperature, there may be a high probability that the subject being measured suffers from cold hands and feet.

The output unit 60 may output data applied from the temperature determination unit 40 as at least one of text and sound according to the control of the temperature determination unit 40.

Accordingly, the output unit 60 may include at least one of a display module that outputs output related to vision and an audio output module that outputs output related to hearing.

Because of this, the sound output module can display an image corresponding to the image data output from the temperature determination unit 40 on the screen.

As an example, the display module may include at least one display device selected from a liquid crystal display, an organic light emitting diode display, a flexible display, and a 3D display. there is.

Additionally, the sound output module can output the audio signal output from the temperature determination unit 40 as a voice by the operation of the temperature determination unit 40.

This audio output module may include a receiver, speaker, or buzzer.

Next, with reference to FIG. 3, the operation of the temperature measuring device having this structure will be described.

First, when the operation switch 10 is operated by the user, the power required for operation of the temperature measuring device is supplied to the temperature measuring device, and the temperature measuring device begins to operate.

Accordingly, the operation of the temperature determination unit 40 begins (S20), and the temperature determination unit 40 can begin the operation of measuring the body temperature of the subject.

When power is supplied to this temperature measuring device, the temperature sensor unit 20 and the pulse wave sensor unit 30 may also start operating.

Therefore, the temperature sensor unit 20 can measure the temperature of the relevant area, generate a temperature measurement signal corresponding to the measured temperature, and output it to the temperature determination unit 40.

In this example, the corresponding part is a part that is in contact with or adjacent to the temperature sensor unit 20. As already described, the temperature measuring device of this example is a wrist-type temperature measuring device worn on the wrist as an example, so the wrist area (e.g., It may be a first measurement site).

The pulse wave sensor unit 30 also operates to measure the pulse wave according to the heart motion of the subject, generates a pulse wave signal corresponding to the measured pulse wave, and outputs the pulse wave signal to the temperature determination unit 40.

In this way, when the temperature sensor unit 20 and the pulse wave sensor unit 30 are operated by the operation of the operation switch 10, the temperature determination unit 40 operates the temperature sensor unit 20 and the pulse wave sensor unit 30, respectively. ) can receive the temperature measurement signal and pulse wave signal applied from and store them in the storage unit 50 (S21).

Then, the temperature determination unit 40 may perform a body temperature measurement operation using the transmitted temperature measurement signal.

Therefore, first, the temperature determination unit 40 can determine the temperature measured by the temperature sensor unit 20 using the transmitted temperature measurement signal (S22). As already described, the temperature measured by the temperature sensor unit 20 is the surface temperature of the corresponding area corresponding to the temperature sensor unit 20, that is, the skin temperature, and therefore the temperature determined using the temperature measurement signal is the wrist skin temperature. (e.g., first measurement temperature).

In this way, when the wrist skin temperature measured by the temperature sensor unit 20 is determined, the temperature determination unit 40 compares the reference temperature stored in the storage unit 50 with the determined wrist skin temperature, It is possible to determine whether the skin temperature is lower than or equal to the reference temperature (S23, S24).

If the wrist skin temperature exceeds the reference temperature (S24), the temperature determination unit 40 may determine that the subject is a normal person, that is, a person who does not suffer from cold hands and feet.

Accordingly, when the wrist skin temperature exceeds the reference temperature (S24), the temperature determination unit 40 may determine the body temperature of the subject using the measured wrist skin temperature. To this end, the temperature determination unit 40 may perform a correction operation to correct the measured wrist skin temperature and convert it into core temperature (S25).

For example, the storage unit 50 may already store a correction value (e.g., a first correction value) for correcting the wrist skin temperature to the core temperature, and therefore, the temperature determination unit 40 stores the storage unit 50. By applying the correction value stored in to the wrist skin temperature, for example, the wrist skin temperature can be corrected to the core temperature by adding.

In this way, when the wrist skin temperature detected by the temperature sensor unit 20 is corrected to the core temperature, the temperature determination unit 40 can output the corrected core temperature to the output unit 60 (S26).

Accordingly, the person being measured can recognize the temperature output to the output unit 60 as his or her own body temperature and check his or her current body temperature.

However, in step S24, if the wrist skin temperature does not exceed the reference temperature and is equal to or less than the reference temperature (S24), the temperature determination unit 40 determines that there is a high possibility that the person being measured is a person suffering from cold hands and feet. Therefore, it is possible to determine whether the subject being measured suffers from cold hands and feet using the pulse wave signal stored in the storage unit 50.

Accordingly, the temperature determination unit 40 can determine the pulse wave measured when the temperature sensor unit 20 is operated using the pulse wave signal stored in the storage unit 50 (S27).

Next, the temperature determination unit 40 may compare the determined pulse wave with the reference pulse wave stored in the storage unit 50 and calculate the waveform difference between the determined pulse wave and the reference pulse wave (S28). At this time, the part of the waveform where the waveform difference is calculated may already be determined.

The reference pulse wave is a waveform generated based on the pulse wave of a normal person who does not suffer from cold hands and feet. After comparing the pulse wave of the subject and the reference pulse wave to determine the waveform difference, if the determined waveform difference exceeds the set value, the temperature The determination unit 40 may determine that the subject being measured is a person suffering from cold hands and feet (S30).

If the calculated waveform difference exceeds the setting value already stored in the storage unit 50 (S29), the temperature determination unit 40 may determine that the subject to be measured is an abnormal person suffering from cold hands and feet.

Therefore, if the calculated waveform difference exceeds the set value already stored in the storage unit 50 (S29), the temperature determination unit 40 determines the temperature of a body part other than the wrist (e.g., the second measured body part). A guidance message for performing measurement can be output to the output unit 60 (S31).

At this time, other body parts are not affected by cold hands and feet, so their average skin temperature is higher than the average wrist skin temperature, and they may be parts where temperature measurement operations can be easily performed by the subject. In this example, the other body part may be the forehead area.

Therefore, the person being measured releases the temperature measuring device worn on the wrist according to the guidance message output from the output unit 60 through at least one of text and sound and places it on the forehead, which is the second body part to be measured, to measure the temperature of the forehead. make it possible

In this way, after outputting the guidance message, the temperature determination unit 40 reads the signal input from the temperature sensor unit 20, that is, the forehead measurement signal corresponding to the forehead skin temperature, and stores it in the storage unit 50 ( S32), a body temperature determination operation can be performed using the temperature measured at the forehead.

Accordingly, the temperature determination unit 40 may determine the forehead skin temperature (eg, the second measurement temperature) using the forehead measurement signal stored in the storage unit 50 (S33).

Next, similar to steps S25 and 26, the forehead skin temperature is corrected using the correction value (e.g., the second correction value) stored in the storage unit 50 to obtain, for example, the forehead skin temperature. After converting it into core temperature by adding a second correction value (S34), the corrected core temperature can be output as the body temperature of the person being measured through the output unit 60 (S35).

The second correction value is for correcting the forehead skin temperature to the core temperature, similar to the first correction value, and can be determined based on the difference between the forehead skin temperature and the core temperature, and is a value smaller than the first correction value. You can have it.

In this way, when measuring the body temperature of a person being measured using a temperature measuring device worn on the wrist, the temperature determination unit 40 determines whether the person being measured is an abnormal person suffering from cold hands and feet whose skin temperature on the hands is lower than that of normal people. You can.

Therefore, if the subject is judged to be abnormal, the temperature of the body part measured by the temperature sensor unit 20 is not the hand or a part adjacent to the hand, but the temperature of another body part (e.g., forehead) that is not significantly affected by coldness. Measurements can be made so that accurate body temperature measurements can be made.

However, in step S29, if the calculated waveform difference does not exceed the set value (S29), the temperature determination unit 40 determines that the subject to be measured is not an abnormal person suffering from cold hands and feet but is normal without cold hands and feet. Therefore, it is possible to proceed to step S25 and measure the body temperature of the subject being measured using the temperature determined in step S22.

However, in this case, that is, if the calculated waveform difference does not exceed the set value (S29), as an alternative example, the temperature determination unit 40 temporarily determines the surface temperature of the first measured body part of the subject to be measured in a low state. It can be judged as follows. Accordingly, the temperature determination unit 40 may output a guidance message to re-perform the body temperature measurement operation through the output unit 60. Accordingly, the subject to be measured operates the operation switch 10 again according to this guidance message to measure the same part (i.e., the first measured body part) by the temperature sensor unit 20 and the pulse wave sensor unit 30. The body temperature measurement operation may be performed again so that the operation of step S21 can be performed.

In the embodiment shown in FIG. 3, if the temperature determination unit 40 determines that the subject being measured is an abnormal person suffering from cold hands and feet, it may change the body part for which the temperature is measured and re-perform the temperature measurement.

However, in another embodiment, the temperature determination unit 40 may change the compensation value for core temperature and perform a temperature determination operation using the temperature measured at the first measured body part.

For example, if the temperature determination unit 40 determines that the subject is abnormally suffering from cold hands and feet through the operation of step S29 (S30), the temperature determination unit 40 selects a third correction value among the correction values stored in the storage unit 50. You can read and perform a correction operation to the core temperature.

At this time, there may be at least one third correction value, and all third correction values may have a value greater than the first correction value.

When there are multiple third correction values, different third correction values may be determined depending on the range of the temperature difference between the wrist skin temperature and the reference temperature.

Accordingly, the temperature determination unit 40 changes the core temperature to perform a correction operation such as reading the third correction value corresponding to the value of the wrist skin temperature and adding it to the wrist skin temperature determined in step S22. It can then be output through the output unit 60.

As already described, the third correction value has a larger value than the first correction value, which is the correction value for temperature correction for normal people who do not suffer from cold hands and feet, so it is used for abnormal people with wrist skin temperature that is relatively lower than that of normal people. The accuracy of skin temperature correction can be improved. Because of this, the accuracy of the core temperature generated after skin temperature correction is also greatly improved, making it possible to accurately measure the body temperature of the subject.

Except for these operations, the operation of the temperature determination unit 40 in this example is the same as the operation described with reference to FIG. 3, and therefore detailed description thereof will be omitted.

In this case, since the temperature measurement operation at the second measurement site different from the first measurement site is unnecessary, the inconvenience to the person being measured can be greatly reduced and the user's satisfaction can be increased.

Therefore, in each embodiment, each technical feature is mainly explained, but unless the technical features are incompatible with each other, they can be applied in combination with each other.
