According to embodiments, the motion sensor 130 may measure at least one of the speed, acceleration, angular velocity, and moving distance of the companion animal PET, and may generate motion data MVD representing the measured at least one. The generated motion data MVD may be stored in the memory 140 .

The controller 160 may perform operations for controlling the operation of the vital sensor 120 based on the motion data MVD. For example, the controller 160 may perform an operation to reduce power consumed by the vital sensor 120 based on the motion data MVD.

According to embodiments, the controller 160 transmits the first control signal CS1 for setting the operating mode of the vital sensor 120 to one of an active mode and an inactive mode based on the motion data MVD ( 120) can be output. The vital sensor 120 may operate according to one of an active mode and an inactive mode in response to the first control signal CS1 .

4 is a diagram for explaining the operation of a controller according to embodiments of the present invention. Referring to FIG. 4 , the motion data MVD, the level of the control signal CS, and the status of the vital sensor are shown.

According to embodiments, the controller 160 compares the motion data MVD and the reference value REF, and generates control signals CS1 and CS2 (commonly referred to as CS) for controlling the vital sensor 120 according to the comparison result. can create The reference value REF may be a value indicating the movement of the companion animal PET in a state suitable for measuring the vital signs of the companion animal.

In the first period (0 to T1), the motion data MVD generated by the motion sensor 130 may be equal to or less than the reference value REF. In this case, the controller 160 may output a first level (eg, low level) control signal CS according to a comparison result between the motion data MVD and the reference value REF. The reference value (REF) may represent the movement of the companion animal (PET) in a state suitable for measuring vital signs.

For example, the vital sensor 120 may operate in an active mode in response to the first level control signal CS. Also, for example, the power circuit 150 may supply power PW to the vital sensor 120 in response to the first level control signal CS.

That is, when the motion data MVD generated by the motion sensor 130 is equal to or less than the reference value REF, the vital sensor 120 operates normally, and the vital sensor 120 detects the vital signs of the companion animal PET. Generates vital data that represents

In the second period T1 to T2, the motion data MVD generated by the motion sensor 130 may exceed the reference value REF. In this case, the controller 160 may output a second level (eg, high level) control signal CS according to a comparison result between the motion data MVD and the reference value REF.

For example, the vital sensor 120 may switch from an active mode to an inactive mode in response to the control signal CS of the second level and operate in the inactive mode. Also, for example, the power circuit 150 may block the power PW supplied to the vital sensor 120 in response to the second level control signal CS.

That is, when the motion data (MVD) generated by the motion sensor 130 exceeds the reference value (REF), the vital sensor 120 operates in an inactive mode or does not operate, so that the vitals of the companion animal (PET) It may not produce vital data indicative of a sign.

In the third period (after T2), the motion data MVD generated by the motion sensor 130 may be equal to or less than the reference value REF. In this case, the controller 160 may output a first level control signal CS according to a comparison result between the motion data MVD and the reference value REF.

Similarly, when the motion data MVD generated by the motion sensor 130 is equal to or less than the reference value REF, the vital sensor 120 operates normally, and the vital sensor 120 measures the vital signs of the companion animal PET. Generates vital data that represents

As described with reference to FIG. 4 , when the motion data MVD generated by the motion sensor 130 exceeds the reference value REF, the vital sensor 120 controls the heartbeat according to the control of the controller 160 . Data may not be generated, and as a result, power consumed by the vital sensor 120 may be reduced. Therefore, according to the embodiments of the present invention, when the movement of the companion animal (PET) is large, the measuring device 100 may not generate inaccurate vital data, and unnecessary power consumption is prevented, so that the measuring device 100 use time can be maximized.

5 is a diagram for explaining the operation of a controller according to embodiments of the present invention. Referring to FIG. 5 , the motion data MVD, the level of the control signal CS, and the status of the vital sensor are shown.

According to example embodiments, the controller 160 may compare the motion data MVD with the reference value REF and generate a control signal CS for controlling the vital sensor 120 according to the comparison result.

For example, as shown in FIG. 5 , in the first period (0 to T1), the motion data MVD generated by the motion sensor 130 may be less than or equal to the reference value REF. In this case, the controller 160 may output a first level (eg, low level) control signal CS according to a comparison result between the motion data MVD and the reference value REF.

For example, the vital sensor 120 may operate in an active mode in response to the first level control signal CS. Also, for example, the power circuit 150 may supply power PW to the vital sensor 120 in response to the first level control signal CS.

Meanwhile, in the second period T1 to T2, the motion data MVD generated by the motion sensor 130 may exceed the reference value REF. In this case, the controller 160 may output a second level (eg, high level) control signal CS according to a comparison result between the motion data MVD and the reference value REF.

For example, the vital sensor 120 may switch from an active mode to an inactive mode in response to the control signal CS of the second level and operate in the inactive mode. Also, for example, the power circuit 150 may block the power PW supplied to the vital sensor 120 in response to the second level control signal CS.

In the third period (after T2), the motion data MVD generated by the motion sensor 130 may be equal to or less than the reference value REF. However, unlike FIG. 4 , even if the motion data MVD is equal to or less than the reference value REF, the controller 160 may not output the first level control signal CS.

In the embodiment of FIG. 5 , the controller 160 calculates the non-active mode operating time (IMOT) of the vital sensor 120 based on the extent to which the motion data MVD exceeds the reference value REF and the length of the section in which the motion data MVD exceeds the reference value REF. can determine The controller 160 may output the first level control signal CS when the inactive mode operation time IMOT exceeds the time point at which the second level control signal CS is output.

For example, as shown in FIG. 5 , the controller 160 may determine the inactive mode operation time IMOT based on the area S2 of the section in which the motion data MVD exceeds the reference value REF. . That is, according to embodiments of the present disclosure, the more and longer the motion data MVD exceeds the reference value REF, the longer the vital sensor 120 operates in the inactive mode. The fact that the movement data (MVD) exceeded the reference value (REF) more and for a longer time means that the movement of the companion animal (PET) was very active, so the state of the companion animal (PET) returned to a stable status. It will take longer for you to rest. Accordingly, vital data measured by the vital sensor 120 after a longer period of time may more accurately represent the vital signs of the companion animal (PET).

For example, the area S2 of the section in which the motion data MVD exceeds the reference value REF in FIG. 5 is greater than the area S2 of the section in which the motion data MVD exceeds the reference value REF in FIG. 4 . ) is smaller, the inactive mode operating time (IMOT) in FIG. 5 may be longer than in FIG. 4 .

According to embodiments, the controller 160 directly calculates the inactive mode operating time (IMOT) from the degree to which the motion data (MVD) exceeds the reference value (REF) and the length of the section in which the motion data (MVD) exceeds the reference value (REF), or uses a pre-stored lookup table The inactive mode operation time (IMOT) can be obtained from

Therefore, according to the embodiments of the present invention, when the movement of the companion animal (PET) is large, the measuring device 100 may not generate inaccurate vital data, and unnecessary power consumption is prevented, so that the measuring device 100 use time can be maximized.

In addition, according to embodiments of the present invention, when the motion of the companion animal (PET) exceeds a predetermined criterion, based on the degree to which the motion exceeds the criterion and the length of time that exceeds the criterion, the vital sensor 120 Since the inactive operating time can be determined, there is an effect of obtaining more accurate vital data.

In order to accurately measure the heart sound of the companion animal (PET), it is preferable to completely exclude friction between the measurement device 100 and the companion animal (PET). However, due to the characteristics of the measurement device 100, which is a wearable device, the material surrounding the surface of the measurement device 100 or the sound of rubbing the skin or fur of a companion animal (PET) on the vital sensor 120 may occur as the largest noise. have. Therefore, in order to hear a specific sound (heartbeat, etc.) inside the body of a companion animal (PET) as intended, it is necessary to derive a unique property of the heartbeat sound that is distinguished from other sounds such as noise and use it to remove the noise. do.

The measuring device 100 may remove noise using physical characteristics of heart sounds (S120). According to embodiments, the measurement device 100 may remove noise using physical characteristics (eg, frequency and pulse characteristics) of heart sounds. For example, the measuring device 100 may filter, as noise, sounds other than sounds of a specific frequency band or a specific beat tempo (beats per minute) band among the measured heart sounds.

For example, the measuring device 100 may extract sounds of 10 Hz to 250 Hz and 80 bpm to 100 bpm of heart sounds by removing noise of the measured heart sound.

The measuring device 100 may remove noise unrelated to the heart sound from the heart sound (S130). For example, the measurement device 100 may remove noise by using various audio analysis algorithms in combination. For example, the measurement device 100 may remove noise using a drum transfer technique, an audio separation technique, and algorithms such as RNN, LSTM, and DBN.

The measuring device 100 may generate heart rate data using heart sounds from which noise has been removed (S120 and S130) (S140).

According to the embodiments of the present invention, a heart sound from which noise has been removed is obtained using the physical characteristics of the measured heart sound, and the heart rate can be measured using the noise-removed heart sound. There is an effect of generating heart rate data that more accurately represents the heart rate.
