Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The flow diagrams depicted in the figures are exemplary only and not necessarily all steps are included. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations. In addition, all of the following terms "first," "second," "third," etc. are used for distinguishing purposes only and should not be taken as a limitation of the present disclosure.

In some technologies, a PPG detection mode is used to detect the heart rate of a user, however, some users are not suitable for the light adopted during PPG detection, so that the use rate of the heart rate detection function of the users is low, and the popularization of products is not facilitated.

The present disclosure provides a new heart rate detection scheme, based on the detection of ballistocardiogram signals and in combination with the response and the displayed strategy, the heart rate detection process is simple, easy to implement and high in accuracy.

Ballistocardiogram (BCG) signals are physiological signals reflecting the vibrations of the body caused by heart beats, and data can be acquired in a non-interfering, non-contact manner. The heart attack signal of a normal person is synchronous with the heart beat and has repeatability.

Fig. 1 shows an exemplary plot of a heart attack signal over a period. Referring to fig. 1, the curve may include characteristic locations such as H, I, J, K, L, M, N, which correspond to extreme points of the ballistocardiogram signal. The amplitude of the peak corresponding to the J point is maximum, so that the interval of the peak of the J point in two adjacent sampling periods is calculated to be used as a heartbeat period, and the real-time heart rate can be determined through the heartbeat period. In addition, the difference in IJ during each cycle may be indicative of the amount of contractile force of the heart pumping blood.

It should be noted that fig. 1 is only a graph showing a ballistocardiogram signal corresponding to one sampling period, and in the case of continuous sampling, a continuous ballistocardiogram signal can be obtained, and thus a real-time heart rate can be detected.

Fig. 2 shows a schematic block diagram of a mobile terminal implementing a heart rate detection scheme of an embodiment of the present disclosure.

Referring to fig. 2, the mobile terminal 2 may include a heart rate detection device 20, a user interaction end 21, and a sensor 22. The user interaction end 21 may include, but is not limited to, a touch screen, and the sensor 22 may include an inertial sensor, which may include an acceleration sensor and/or a gyro sensor. In addition, the sensor 22 may also include a piezoelectric sensor.

In the heart rate detection scheme of the present disclosure, first, a user may trigger a heart rate detection trigger event through the user interaction terminal 21. For example, the user clicks into the heart rate detection interface.

Next, the heart rate detection device 20 may acquire sensed data from the sensor 22 in response to a heart rate detection trigger event to enable real-time acquisition of the ballistocardiographic signal. For example, the acceleration sensor and the gyro sensor may acquire the same form of ballistocardiographic signal as shown in fig. 1. For another example, the piezoelectric sensor may convert a periodic body vibration signal into a ballistocardiographic signal as shown in fig. 1.

Subsequently, the heart rate detection device 20 may detect the motion state of the user according to the ballistocardiogram signal, and in the case that the motion state of the user meets the heart rate detection requirement, the heart rate detection device 20 determines the heart rate by using the ballistocardiogram signal acquired in real time, and displays the determined heart rate to the user through the user interaction terminal 21.

The heart rate detection method of the embodiments of the present disclosure is performed by a mobile terminal, that is, the mobile terminal may perform the respective steps of the heart rate detection method of the embodiments of the present disclosure. In this case, a heart rate detection apparatus described below may be provided in the mobile terminal.

Mobile terminals described in this disclosure include, but are not limited to, smart phones, tablet computers, smart wearable devices, and the like.

Fig. 3 schematically shows a flow chart of a heart rate detection method of an exemplary embodiment of the present disclosure. Referring to fig. 3, the heart rate detection method may include the steps of:

s32, responding to a heart rate detection trigger event, acquiring a ballistocardiogram signal, and detecting the motion state of the user according to the ballistocardiogram signal.

In an exemplary embodiment of the present disclosure, the heart rate detection trigger event may be any event for triggering the heart rate detection process, that is, the heart rate detection process of embodiments of the present disclosure is started when the heart rate detection trigger event occurs. The present disclosure does not limit the heart rate detection trigger event, for example, in the health app interface of the mobile terminal, the user clicks the heart rate detection button; for another example, the mobile terminal enters an interface for heart rate detection.

In exemplary embodiments of the present disclosure, the user motion state may characterize the degree of shaking of the user's body.

And when the mobile terminal detects that the heart rate detection triggering event occurs, acquiring a heart shock signal. Specifically, the ballistocardiographic signal may be acquired in real time, that is, the ballistocardiographic signal is acquired in real time.

According to some embodiments of the present disclosure, the mobile terminal may obtain the ballistocardiographic signal by means of an inertial sensor it is equipped with. The inertial sensor may comprise an acceleration sensor and/or a gyroscopic sensor. The acceleration sensor and the gyro sensor can acquire the same form of ballistocardiographic signal, one cycle of which is shown in fig. 1.

In addition, in response to the heart rate detection trigger event, a parameter value of the inertial sensor may be adjusted, and a ballistocardiogram signal may be determined based on the inertial sensor after the adjustment of the parameter value. Specifically, the measuring range of the inertial sensor can be reduced, so that data noise is reduced, and the accuracy of heart rate detection is improved.

It should be noted that in embodiments where the parameter values are adjusted, after the final heart rate detection result is determined, i.e. after stopping heart rate detection, the parameter may be restored to the parameter values before adjustment to meet the needs of other scenarios (e.g. step number measurement, etc.).

Since most mobile terminals are equipped with inertial sensors, heart rate detection is performed by using the sensing results of the inertial sensors, and hardware cost is reduced.

According to other embodiments of the present disclosure, the mobile terminal may also obtain a ballistocardiographic signal by means of its equipped piezoelectric sensor. The heart beats to drive the user's body to vibrate periodically, and the piezoelectric sensor can convert the periodic human vibration signal into a heart attack signal.

Similarly, in response to a heart rate detection trigger event, the parameter values of the piezoelectric sensor may be adjusted and, after the heart rate detection result is determined, the parameters are restored to the parameter values prior to adjustment.

After determining the ballistocardiogram signal, the mobile terminal can detect the motion state of the user according to the ballistocardiogram signal acquired in real time.

According to some embodiments of the present disclosure, first, a mobile terminal may extract a feature point from a ballistocardiogram signal, wherein the feature point includes an extreme point of the ballistocardiogram signal. Such as corresponding to the characteristic location points H, I, J, K, L, M, N shown in fig. 1.

Next, the mobile terminal calculates a motion evaluation value from the feature points, for example, taking the interval of J-point peaks in two adjacent periods as the motion evaluation value. In this case, the exercise evaluation value is characterized by the time corresponding to the interval.

Then, the exercise evaluation value is compared with an exercise threshold value, and the exercise state of the user is determined according to the comparison result. Under the condition that the exercise evaluation value is smaller than the exercise threshold value, the fact that the user does not shake currently or the shaking degree is small is indicated, and the exercise state of the user meets the heart rate detection requirement; under the condition that the exercise evaluation value is greater than or equal to the exercise threshold value, the current shaking degree of the user is large, and the exercise state of the user does not meet the heart rate detection requirement.

The present disclosure does not limit the motion threshold, and in the case of taking time as a criterion, the motion threshold may be a time threshold set in advance.

According to other embodiments of the present disclosure, the energy value generated by the sensor may be utilized to determine the user motion state. Taking inertial sensors as an example, the Energy value Energy generated by the sensor can be characterized by the following formula:

where x, y, z are data generated by the acceleration sensor or gyroscope sensor on each axis, and N represents the total number of data points calculated.

Similarly, an energy threshold may be preset, the calculated energy value may be compared with the energy threshold, and the user movement state may be determined based on the comparison result.

In addition, in a first preset time period after the occurrence of the heart rate detection triggering event, if the movement state of the user is detected not to meet the heart rate detection requirement, stopping heart rate detection. In some embodiments, in this case, the mobile terminal may output an interface that characterizes the absence of a test result or failure to detect.

The specific value of the first preset time period is not limited in the present disclosure, for example, the first preset time period may be set to 60s, that is, in response to a heart rate detection trigger event, a countdown for 60s is started, if during the countdown period, it is detected that the motion state of the user does not meet the heart rate detection requirement, and then the mobile terminal stops heart rate detection when the countdown is finished. If during the countdown, it is detected that the user motion state meets the heart rate detection requirement, the countdown is cancelled or controlled to stop to perform the heart rate detection process subsequent to the present disclosure.

In addition, in a first preset time period after the occurrence of the heart rate detection trigger event, if the movement state of the user is detected to not meet the heart rate detection requirement, reminding information is sent out. The form of sending the reminding information comprises one or a combination of a plurality of voice broadcasting, text information reminding and mobile terminal vibration, so that a user is reminded to keep the body stationary.

For the time of sending the reminding information, in one embodiment, the reminding information can be sent each time the movement state of the user is detected to not meet the heart rate detection requirement. In another embodiment, the alert message may be sent every predetermined time (e.g., 5 s) to reduce the user's boring sensation.

S34, under the condition that the motion state of the user meets the heart rate detection requirement, determining the heart rate by using the obtained heart attack signal.

For the process of determining heart rate using ballistocardiographic signals, as described above, the time interval between extreme points of maximum amplitude in each sampling period can be used for estimation.

For continuous heart attack signals, the number of the attack peaks shown in fig. 1 generated in a period of time can be identified after filtering processing such as band-pass filtering, or the frequency point where the heart rate is located can be determined from the frequency domain through fourier transformation, so that the heart rate value can be obtained.

Under the condition that the mobile terminal determines that the motion state of the user meets the heart rate detection requirement, the heart rate can be determined by using the heart attack signals acquired in real time. That is, the ballistocardiogram signal used for determining the heart rate is a ballistocardiogram signal acquired in real time after the heart rate detection requirement is initially satisfied.

And acquiring a heart shock signal in a second preset time period in real time from the moment when the motion state of the user starts to meet the heart rate detection requirement, determining a first heart rate detection result according to the heart shock signal in the second preset time period, and displaying the first heart rate detection result. The second preset time period is not limited, for example, within 8s from the moment when the heart rate detection requirement begins to be met, that is, from the moment when the motion state of the user begins to meet the heart rate detection requirement, timing begins, and the first heart rate detection result is determined by using the heart attack signal acquired within 8 s. For the user side, the first heart rate detection result displayed by the mobile terminal can be seen after 8s from the beginning of the user movement state to meet the heart rate detection requirement. In addition, in some embodiments, the second preset time period may also coincide with the first preset time period described above.

The heart rate detection results of the present disclosure include at least a heart rate value. In addition, a normal or abnormal detection state may be included. Wherein, the motion state of the user meets the heart rate detection requirement and corresponds to the normal detection state; the motion state of the user does not meet the heart rate detection requirement and corresponds to the abnormal detection state.

In some embodiments of the present disclosure, the mobile terminal may denoise the ballistocardiogram signal in the second preset time period, and determine the first heart rate detection result according to the denoised ballistocardiogram signal. For example, the heart attack signal may be denoised by a motion threshold, which may or may not be different from the motion threshold described above for determining whether heart rate detection requirements are met, as used herein, and this disclosure is not limited in this regard.

The first heart rate detection result is a first heart rate detection result presented to the user. The heart rate detection result for the first presentation is determined by using the heart attack signal in the second preset time period, and the accumulated data is statistically analyzed, so that the reliability of the presentation of the heart rate result is improved.

After a second preset time period, the mobile terminal further acquires a heart attack signal in real time, determines a second heart rate detection result by using the acquired heart attack signal, and displays the second heart rate detection result in real time. It should be noted that, because the second heart rate detection result is determined in real time, the number of second heart rate detection results is plural, that is, the mobile terminal may continuously refresh the display interface to continuously display the determined second heart rate detection result in real time.

According to some embodiments of the present disclosure, the mobile terminal may compare, in real time, the heart rate value included in the second heart rate detection result with the heart rate threshold range, and count the number of heart rate values in the heart rate threshold range, that is, once the heart rate value falls into the heart rate threshold range, the count is incremented by 1, and the number of heart rate values in the heart rate threshold range is determined in real time by means of accumulation. The heart rate threshold range is not limited, and the heart rate threshold range can be a preset threshold range representing the accuracy of the heart rate value, namely, the heart rate value is accurate when the heart rate threshold range is fallen into, and the heart rate value accuracy is reduced when the heart rate value is not fallen into the heart rate threshold range, so that the user possibly has shaking conditions.

When the number of heart rate values in the heart rate threshold range is greater than or equal to the number threshold, the mobile terminal can determine a third heart rate detection result according to the first heart rate detection result and the second heart rate detection result, stop heart rate detection and display the third heart rate detection result. The third heart rate detection result is a finally determined heart rate detection result. In addition, embodiments of the present disclosure do not limit the specific value of the numerical threshold.

Specifically, the heart rate value included in the first heart rate detection result and the heart rate value included in the second heart rate detection result may be obtained, and an average value of the heart rate value included in the first heart rate detection result and the heart rate value included in the second heart rate detection result is calculated as the heart rate value included in the third heart rate detection result.

It will be appreciated that the process of determining and presenting the second heart rate detection result continues when the number of heart rate values in the heart rate threshold range is less than the number threshold.

According to other embodiments of the present disclosure, the mobile terminal may compare, in real time, the heart rate value included in the second heart rate detection result with the heart rate threshold range, and count the number of heart rate values within the heart rate threshold range.

In a third preset time period after the second preset time period, if the number of heart rate values in the heart rate threshold range is greater than or equal to the number threshold, when the number of heart rate values in the heart rate threshold range is greater than or equal to the number threshold, the mobile terminal can determine a third heart rate detection result according to the first heart rate detection result and the second heart rate detection result, stop heart rate detection and display the third heart rate detection result. The third preset time period is not limited in this embodiment, for example, 17s from the end of the second preset time period. In addition, a total time period, such as 25s, may be preconfigured, and the 25s may be divided into a second preset time period and a third preset time period to perform different processing procedures.

After a third preset time period after the second preset time period, if the number of heart rate values in the heart rate threshold range is smaller than the number threshold, the mobile terminal can determine a third heart rate detection result according to the first heart rate detection result and the second heart rate detection result, stop heart rate detection and display the third heart rate detection result. That is, the mobile terminal calculates the third heart rate detection result at the end of the third preset time even if the number of heart rate values with high accuracy does not reach the number threshold.

Similarly, in these embodiments, the third heart rate measurement is the final determined heart rate measurement. In addition, the mobile terminal may calculate an average of the heart rate value included in the first heart rate value detection result and the heart rate value included in the second heart rate detection result as the heart rate value included in the third heart rate detection result.

According to further embodiments of the present disclosure, after a third preset time period after the second preset time period, the mobile terminal may determine a third heart rate detection result according to the first heart rate detection result and the second heart rate detection result, stop heart rate detection and display the third heart rate detection result.

In addition, in each embodiment of determining the third heart rate detection result, the mobile terminal may further obtain heart rate health information corresponding to the third heart rate detection result, and display the heart rate health information. The heart rate health information comprises, but is not limited to, a reason for high heart rate value and a corresponding health prompt, a reason for low heart rate value and a corresponding health prompt and heart rate science popularization information.

In the case where the heart rate health information is obtained based on a web search, the provenance of the heart rate health information may also be displayed, which is not limited by the present disclosure.

In order to better illustrate the effects of the embodiments of the present disclosure, fig. 4 shows an interface schematic diagram of a mobile terminal according to an embodiment of the present disclosure displaying an intermediate heart rate detection result, where the intermediate heart rate detection result may be the first heart rate detection result or the second heart rate detection result.

Referring to fig. 4, in addition to the heart rate value detected in real time, the detected remaining time may be displayed on the interface of the mobile terminal, which corresponds to the countdown result of the third preset time period. In addition, prompt words such as "please keep body disabled, don't speak" may also be displayed to ensure accuracy of the heart rate test as much as possible.

Fig. 5 shows an interface schematic diagram of a mobile terminal displaying a final heart rate detection result according to an embodiment of the disclosure, where the final heart rate detection result corresponds to the third heart rate detection result.

Referring to fig. 5, in addition to the average heart rate value detected at this time, the interface of the mobile terminal may also display information such as the test time and heart rate science popularization of the detection at this time.

In addition, before the final heart rate detection result is determined, the mobile terminal may respond to the heart rate detection stop time to stop heart rate detection. The heart rate detection stopping event may be an onPause event of the mobile terminal, for example, the heart rate test interface is moved back to the background, the user clicks to notify to jump to other applications or tasks, etc. The present disclosure is not particularly limited to heart rate detection events.

The interactive process of detecting heart rate of embodiments of the present disclosure will be described with reference to fig. 6.

In step S602, the user determines whether the mobile terminal supports the heart rate detection function through an AI (Artificial Intelligence ) assistant of the mobile terminal.

In step S604, the AI assistant starts the corresponding health app to start heart rate detection when determining that the mobile terminal supports the heart rate detection function.

In step S606, the health app performs a detection countdown as 60S, that is, after 60S, the heart rate detection task ends.

In step S608, the health app registers a sensor with the system.

In step S610, the system turns on the sensor for sensing and controls the sensor to be automatically turned off after 90S, for example.

In step S612, the system may return data sensed by the sensor to the health app.

In step S614, the health app will send data for calculating the heart rate to the algorithm module of the disclosed embodiments, which calculates the heart rate.

In step S616, the algorithm module returns the heart rate result to the health app.

In step S618, the health app presents the heart rate results to the user through the interface and may store the heart rate results to a database for subsequent performance of heart rate comparison, analysis, and the like.

According to the heart rate detection method, the heart impact signal is obtained by using the inertial sensor or the piezoelectric sensor which is usually equipped in the mobile terminal, the range of equipment for heart rate detection is expanded, and the friendliness of products can be improved especially for users who are not suitable for PPG light detection. In addition, based on the strategy of determining the heart rate in the above embodiment, the accuracy of heart rate detection can be improved.

Further, the present disclosure also provides another heart rate detection method applied to a mobile terminal, referring to fig. 7, the heart rate detection method may include the following steps:

s72, responding to heart rate detection triggering operation, acquiring a heart shock signal, detecting the motion state of a user according to the heart shock signal, and sending out reminding information under the condition that the motion state of the user does not meet the heart rate detection requirement.

The form of sending the reminding information comprises one or a combination of a plurality of voice broadcasting, text information reminding and mobile terminal vibration so as to remind the user to keep the body stationary.

S74, respectively displaying a plurality of heart rate detection results after a preset time length under the condition that the motion state of the user meets the heart rate detection requirement.

The predetermined time period may correspond to the second preset time period. For example, after 8s from the moment when the motion state of the user starts to meet the heart rate detection requirement, the mobile terminal may continuously display a plurality of heart rate detection results, for example, by refreshing the interface.

S76, determining a final heart rate detection result based on the heart rate detection results, and displaying the final heart rate detection result.

As described in the above step S34, by limiting the number of heart rate values within the heart rate threshold and/or the third preset period, a final heart rate detection result may be determined based on the determined plurality of heart rate detection results, and the final heart rate detection result may be displayed on the interface. That is, the content displayed at this time is locked even if the final heart rate detection result.

Taking a mobile phone as an example, a user holds the mobile phone by hand, clicks a heart rate detection button of a health app interface on the mobile phone, and enters a heart rate detection page. At this time, the mobile phone continuously judges whether the motion state of the user meets the heart rate detection requirement through the data sensed by the inertial sensor. And under the condition that the heart rate detection requirement is met, determining the heart rate through the heart attack signal.

For the user, after clicking to enter the heart rate detection page, if the movement state of the user meets the heart rate detection requirement, after a preset time, the mobile phone page refreshes the heart rate detection result in real time, and finally, a final heart rate detection result is fixedly displayed, and the heart rate detection is finished.

It should be noted that although the steps of the methods in the present disclosure are depicted in the accompanying drawings in a particular order, this does not require or imply that the steps must be performed in that particular order, or that all illustrated steps be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc.

Further, in this example embodiment, a heart rate detection device applied to a mobile terminal is also provided.
