[0058] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a heart sound data measuring device, etc. The following takes the heart sound data measuring device as an example to illustrate this embodiment and the following embodiments.

[0059] Based on this, the present application embodiment provides a heart sound data measurement method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the heart sound data measurement method of the present application.

[0060] In this embodiment, the heart sound data measurement method includes steps S10 to S40:

[0061] Step S10: if it is detected that the user's status in the preset time period is the preset status, then the initial heart sound data of the user in the current time period is obtained.

[0062] It should be noted that the heart sound data measurement device of this embodiment includes multiple preset conduction devices, a measurement controller, a state detection device, and a preset playback device. The preset conduction device may be a bone conduction sensor, which can only collect vibration data in the vertical direction. In order to solve the dependence on the user's posture, this embodiment is designed to use multiple preset conduction devices. Figure 2 , Figure 2 The schematic diagram of the position of the preset conduction device specifically includes the preset conduction devices VPUz and VPUx, wherein the preset conduction device VPUz is arranged at the bottom for measuring the heart sound data of the z axis, and the preset conduction device VPUx is arranged at the side for measuring the heart sound data of the x axis. The measurement controller may be a central processing unit (CPU), the state detection device may be an inertial measurement unit (IMU) or an acceleration sensor, and the preset playback device may be a speaker for prompting the user to operate, for example, to keep still.

[0063] It should be understood that the preset state can be a static state, and the device used to detect the user's state can be a conventional processing device. When it is detected that the user's state in the preset time period is the preset state, it indicates that the conditions for measuring heart sound data are met. At this time, multiple preset conduction devices are used to collect the user's initial heart sound data in the current time period. The preset time period can be 2 seconds, and the current time period can be 5 seconds.

[0064] Step S20: determining the user's current heart sound quality level according to the initial heart sound data based on a quality assessment model.

[0065] It can be understood that the quality assessment model refers to a model used to evaluate the quality level of heart sounds. The input of the quality assessment model is heart sound data, and the output is the heart sound quality level. That is, after obtaining the user's initial heart sound data in the current time period, the quality assessment model is used to evaluate the user's current heart sound quality level.

[0066] Furthermore, before step S20, it also includes: acquiring historical heart sound data of different types of users; segmenting the historical heart sound data according to a preset window length and a preset overlapping length between windows to obtain the historical heart sound data in each window segment; normalizing the historical heart sound data in each window segment according to a preset numerical range to obtain a target heart sound data sample set; performing feature extraction on the target heart sound data sample set to obtain target sample heart sound features; acquiring a score of the target sample heart sound features by a target professional subject, and determining a grade of the target sample heart sound features according to the score; and training a quality assessment model according to the target sample heart sound features and the grade.

[0067] It should be understood that in order to effectively improve the accuracy of the quality assessment model, the sample data used to train the quality assessment model needs to include historical heart sound data of different types of users, and the types of users include but are not limited to healthy people, hypertensive people, and hypotensive people. After obtaining the historical heart sound data of different types of users, the historical heart sound data are segmented into historical heart sound data in each window segment according to the preset window length and the preset overlap length between windows. The preset window length and the preset overlap length between windows can be flexibly set according to actual needs. For example, the preset window length can be 5 seconds, and the preset overlap length between windows can be 3 seconds. Then, the historical heart sound data in each window segment is normalized according to the preset numerical range, so that the numerical range of the historical heart sound data in each window segment is between 0 and 1.

[0068] It can be understood that after obtaining the target heart sound data sample set, it is necessary to obtain the target sample heart sound characteristics by feature extraction. The target sample heart sound characteristics include but are not limited to mean, standard deviation, peak mean, peak standard deviation, peak interval mean, peak interval standard deviation and spectral energy characteristics, etc. The target professional object can be a professional clinician, that is, the target professional object scores and labels the target sample heart sound characteristics. At this time, the levels of the target sample heart sound characteristics are divided into high, medium, low and very low, and then a decision tree can be used to train a quality assessment model based on the target sample heart sound characteristics and levels.

[0069] Furthermore, after step S20, it also includes: when the current heart sound quality level is lower than or equal to the preset level, generating position movement prompt information; controlling the preset playback device to play the position movement prompt information; detecting the user's position at the current moment in real time; if the user's position at the current moment is inconsistent with the position at the previous moment, continuing to execute the step of detecting whether the user's status in the preset time period is the preset status.

[0070] It can be understood that when it is determined that the current heart sound quality level is lower than or equal to the preset level, it indicates that the quality of the initial heart sound data is too poor and does not meet the quality requirements. At this time, the user needs to be prompted to change the collection position. Specifically, the preset playback device plays the position movement prompt information, and then it will be judged in real time whether the user's position at the current moment is consistent with the position at the previous moment. If not, it indicates that the user has changed the collection position. At this time, it continues to detect whether the user's status in the preset time period is the preset status. If so, continue to execute the step of obtaining the user's initial heart sound data in the current time period.

[0071] Step S30, when the current heart sound quality level is higher than a preset level, determining a target heart sound data direction angle.

[0072] It should be understood that the preset level can be a low level. When it is determined that the current heart sound quality level is higher than the preset level, it indicates that the quality of the initial heart sound data meets the quality requirements. At this time, the target heart sound data direction angle is determined, wherein the target heart sound data direction angle can be the angle formed by the heart sound data of different number axes.

[0073] Further, step S30 includes: when the current heart sound quality is equal to or higher than a preset level, obtaining the acquisition frequency, acquisition duration and acquisition direction of multiple preset conduction devices; determining the number of initial heart sound data according to the acquisition frequency and the acquisition duration; calculating the average value of the initial heart sound data within the acquisition duration according to the number and the initial heart sound data; determining the target heart sound data direction angle according to the average value of the initial heart sound data and the acquisition direction.

[0074] It can be understood that the number of initial heart sound data refers to the total number of preset conduction devices collected by the preset conduction device. Different collection frequencies and collection durations will result in different numbers of initial heart sound data. For example, if the collection frequency is 8000 Hz and the collection duration is 5 seconds, the number of initial heart sound data in each axis direction is 40000. Then, the average value of the initial heart sound data is calculated using this number to obtain the average value of the initial heart sound data within the collection duration. For example, the average value of the initial heart sound data on the x-axis within 5 seconds is R x The average value of the initial heart sound data on the z axis within 5 seconds is R z , and then the acquisition direction determines the target heart sound data direction angle, for example, the vector direction θ = (R x ,R z ) as the main vibration direction.

[0075] Step S40: When it is determined that the initial heart sound data does not meet the preset heart sound data requirement, the heart sound data of the user is measured again according to the target heart sound data direction angle.

[0076] It should be understood that the preset heart sound data requirement refers to the requirement for measuring the user's heart sound data. For example, the preset heart sound data requirement refers to the need to measure 10 seconds of heart sound data, but the initial heart sound data is only 5 seconds. At this time, it is determined that the initial heart sound data does not meet the preset heart sound data requirement. At this time, it is necessary to use the target heart sound data direction angle to measure 5 seconds of heart sound data again. At this time, the position for measuring the heart sound data is the optimal measurement position, and the quality level of the measured heart sound data is high. The above-mentioned method of measuring the user's heart sound data can be applicable to both professional and non-professional people, so as to achieve the purpose of adapting to a variety of people.

[0077] Further, step S40 includes: obtaining preset heart sound data requirements; determining the time period of required heart sound data according to the preset heart sound data requirements; determining the time period difference when the time period of required heart sound data is greater than the current time period corresponding to the initial heart sound data; and measuring the user's heart sound data again according to the time period difference and the target heart sound data direction angle.

[0078] It can be understood that the time period difference refers to the difference between the time period of the required heart sound data and the current time period. For example, if the time period of the required heart sound data is 10 seconds and the current time period is 5 seconds, then the current time period is 5 seconds. After determining the time period difference, the target heart sound data direction angle is used to measure 5 seconds of heart sound data again.

[0079] Furthermore, the step of re-measuring the user's heart sound data based on the time period difference and the target heart sound data direction angle includes: obtaining heart sound data on a first number axis and heart sound data on a second number axis based on initial heart sound data; performing vector projection on the heart sound data on the first number axis and the heart sound data on the second number axis with the target heart sound data direction angle respectively to obtain a scalar heart sound data; determining the heart sound data intensity based on the scalar heart sound data; and re-measuring the user's heart sound data based on the time period difference and the heart sound data intensity.

[0080] It should be understood that the initial heart sound data includes the heart sound data on the first number axis and the heart sound data on the second number axis. After determining the direction angle of the target heart sound data, the heart sound data on the first number axis and the heart sound data on the second number axis are respectively vector-projected with the direction angle of the target heart sound data. At this time, the heart sound data on the first number axis and the heart sound data on the second number axis are processed into one path of scalar heart sound data, and then the value of one path of scalar heart sound data is used to determine the intensity of the heart sound data, and the heart sound data of the user is measured again using the intensity of the heart sound data.

[0081] In this embodiment, if it is detected that the user's status in the preset time period is all the preset status, then the initial heart sound data of the user in the current time period is obtained; based on the quality assessment model, the current heart sound quality level of the user is determined according to the initial heart sound data; when the current heart sound quality level is higher than the preset level, the target heart sound data direction angle is determined; when it is determined that the initial heart sound data does not meet the preset heart sound data requirements, the heart sound data of the user is measured again according to the target heart sound data direction angle; through the above method, the initial heart sound number is obtained based on multiple preset conduction devices, and then the current heart sound quality level is determined by using the quality assessment model, and it is judged whether the current heart sound quality level is higher than the preset level. If so, it indicates that the quality is good. At this time, it is judged whether it is necessary to continue measuring according to the preset heart sound data requirements. If so, the user's heart sound data is measured again, thereby effectively improving the accuracy of measuring heart sound data and being suitable for a variety of people.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S10 includes steps S101 to S103:

[0083] Step S101, when a request for collecting heart sounds is received, a status detection device is started.

[0084] It should be noted that when a heart sound collection request is received, it indicates that the user's heart sound data needs to be collected. At this time, a state detection device is started. The state detection device can be an inertial processing unit or an acceleration sensor, which is used to detect the user's state in a preset time period.

[0085] Step S102, obtaining the user's state in a preset time period based on the started state detection device.

[0086] It should be understood that the user's state during the preset time period can be a stationary state or a moving state.

[0087] Step S103: if the user's status in the preset time period is all the preset status, initial heart sound data of the user in the current time period is obtained according to a preset acquisition method based on multiple preset conduction devices.

[0088] It can be understood that if it is determined that the user's status in the preset time period is the preset status, it means that the user has remained still in the preset time period. The preset collection method refers to the method of obtaining the initial heart sound data. The preset collection method can be a vibration method. At this time, multiple preset conduction devices are used to obtain the user's initial heart sound data in the current time period in the preset collection method. In addition, if the status is not the preset status at any time in the preset time period, it will be re-measured. At this time, the preset playback device will also be used to play information prompting the user to remain still.

[0089] This embodiment starts the state detection device upon receiving a heart sound collection request; obtains the state of the user in a preset time period based on the started state detection device; if the state of the user in the preset time period is all the preset state, obtains the initial heart sound data of the user in the current time period according to a preset collection method based on multiple preset conduction devices; through the above method, the state of the user in the preset time period is obtained by using the started state detection device, and then it is determined whether the state of the user in the preset time period is all the preset state. If not, re-measurement is performed; if so, the initial heart sound data of the user in the current time period is obtained by using multiple preset conduction devices in a preset collection method, thereby effectively improving the accuracy of obtaining the initial heart sound data.

[0090] For example, to help understand the implementation process of the heart sound data measurement method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4 A brief flowchart of a heart sound data measurement method is provided, specifically:

[0091] When a heart sound collection request is received, a status detection device is turned on to detect the status of the user in a preset time period. If it is detected that the status of the user in the preset time period is not all the preset status, the preset playback device is controlled to play a message prompting the user to remain still, and re-measurement is performed. If it is detected that the status of the user in the preset time period is all the preset status, the initial heart sound data of the user in the current time period is obtained, and then the quality assessment model is used to evaluate the current heart sound quality level of the user based on the initial heart sound data. When the current heart sound quality level is lower than or equal to the preset level, the preset playback device is controlled to play a position movement prompt message to remind the user to change the collection position and re-measure. When the current heart sound quality level is higher than the preset level, the target heart sound data direction angle is determined, and then it is determined whether the initial heart sound data meets the preset heart sound data requirements. If so, the heart sound data of the user is measured again according to the target heart sound data direction angle, and the final heart sound data is displayed.

[0092] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the heart sound data measurement method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0093] This application also provides a heart sound data measurement device, please refer to Figure 5 , the heart sound data measuring device comprises:

[0097] The measuring module 40 is used to measure the user's heart sound data again according to the target heart sound data direction angle when it is determined that the initial heart sound data does not meet the preset heart sound data requirement.

[0098] In this embodiment, if it is detected that the user's status in the preset time period is all the preset status, then the initial heart sound data of the user in the current time period is obtained; based on the quality assessment model, the current heart sound quality level of the user is determined according to the initial heart sound data; when the current heart sound quality level is higher than the preset level, the target heart sound data direction angle is determined; when it is determined that the initial heart sound data does not meet the preset heart sound data requirements, the heart sound data of the user is measured again according to the target heart sound data direction angle; through the above method, the initial heart sound number is obtained based on multiple preset conduction devices, and then the current heart sound quality level is determined by using the quality assessment model, and it is judged whether the current heart sound quality level is higher than the preset level. If so, it indicates that the quality is good. At this time, it is judged whether it is necessary to continue measuring according to the preset heart sound data requirements. If so, the user's heart sound data is measured again, thereby effectively improving the accuracy of measuring heart sound data and being suitable for a variety of people.
