acquiring fingerprint data through a fingerprint data acquisition device, and calculating the duty ratio of the fingerprint data;
when the ratio of the fingerprint data exceeds a set threshold, at least one measuring point is selected in a data acquisition area of the fingerprint data acquisition device at intervals of a first set time, the change times of the fingerprint data on the measuring point in a second set time are obtained, and the corresponding heart rhythm value is calculated through the change times.
In order to better use the mobile terminal 100, so that the process of detecting the heart rhythm is more convenient and better user experience is obtained, the embodiment of the invention also provides a heart rhythm detection method, which is applied to the mobile terminal 100, wherein a flow chart of the heart rhythm detection method is shown in fig. 3, and the specific steps are as follows:
step S101, providing at least one heart rhythm detection mode for a user to select setting; wherein, the heart rhythm detection mode comprises manual detection and automatic detection.
When the user turns on the heart rate detection, the mobile terminal 100 provides at least one heart rate detection mode for the user to select settings, wherein the heart rate detection mode comprises manual detection and automatic detection. When the setting is selected, a selection interface can be popped up in the form of a dialog box so that a user can select different heart rhythm detection modes.
Step S102, fingerprint data are acquired through a fingerprint data acquisition device, and the fingerprint data duty ratio is calculated.
In the existing mobile terminal devices such as smart phones, most of the mobile terminal devices have a fingerprint identification function, and the existing fingerprint identification technology is generally used for fingerprint unlocking and has an identity verification function. The change of the heart rhythm may cause weak jump on the surface of the finger skin, so that the fingerprint data collected on the surface of the finger skin may also change periodically, so in the embodiment of the present invention, the heart rhythm may be detected by using the fingerprint data, so that the user may simply and quickly detect the heart rhythm by using the mobile terminal 100 independently, without adding an additional device for detecting the heart rhythm.
Specifically, when the user selects to set the mode of detecting the heart rhythm to be manual detection, the operation interface of the mobile terminal 100 includes a "start" option, and after receiving a start instruction from the user, the mobile terminal 100 may specifically start the fingerprint data acquisition device after receiving the "start" option on the user click operation interface, at this time, the user presses a finger on the fingerprint data acquisition device, the fingerprint data acquisition device acquires fingerprint data, and calculates a fingerprint data duty ratio. Further, after the finger of the user leaves the fingerprint data acquisition device, the fingerprint data acquisition device cannot be immediately closed, and in a fixed time period, the user does not press the finger on the fingerprint data acquisition device, and at the moment, the fingerprint data acquisition device is closed, so that the purpose of reducing power consumption is achieved. Wherein, the fixed duration may be 3min.
When the user chooses to set the heart rhythm detection mode to be automatic detection, the "start" option is not required to be included on the operation interface of the mobile terminal 100. In this arrangement, the fingerprint data collection device will remain closed when no pressing signal is detected, and the mobile terminal 100 will turn on the fingerprint data collection device and acquire the fingerprint data to calculate the fingerprint data duty ratio when a pressing signal is detected. Specifically, after the user selects to set, the mobile terminal 100 will not immediately turn on the fingerprint data collection device, and the fingerprint data collection device is still in a closed state, when a pressing signal is generated, that is, when the finger of the user presses, the mobile terminal 100 detects the pressing signal, specifically, after the fingerprint data collection device detects the pressing signal, the fingerprint data collection device is turned on to obtain the fingerprint data, and the fingerprint data duty ratio is calculated. Further, the pressing signal disappears after the finger of the user leaves the fingerprint data collection device, so that the mobile terminal 100 will immediately turn off the fingerprint data collection device.
Preferably, the fingerprint data may include a fingerprint number and a fingerprint profile.
When the fingerprint data is the fingerprint number, the step S102 may be: and obtaining the fingerprint number collected by the fingerprint data collection device, dividing the collected fingerprint number by the fingerprint number of the complete fingerprint, and calculating to obtain the fingerprint data duty ratio. When a user presses a finger on the fingerprint data acquisition device each time, the acquired fingerprint numbers are different, so that different fingerprint data duty ratios can be calculated according to different fingerprint numbers.
When the fingerprint data is a fingerprint profile, the step S102 may be: and obtaining the fingerprint profile acquired by the fingerprint data acquisition device, dividing the occupied area of the acquired fingerprint profile by the occupied area of the fingerprint profile of the complete fingerprint, and calculating the fingerprint data duty ratio. At this time, the fingerprint data duty ratio is the integrity of the corresponding fingerprint under different pressing conditions.
And step 103, when the ratio of the fingerprint data exceeds a set threshold, selecting at least one measuring point in a data acquisition area of the fingerprint data acquisition device at intervals of a first set time, acquiring the change times of the fingerprint data on the measuring point in a second set time, and calculating the corresponding heart rhythm value according to the change times.
To ensure accuracy of heart rhythm detection, in this embodiment, the set threshold is 80%, that is, when the fingerprint data is more than 80%, the subsequent step of heart rhythm detection may be performed.
And when the fingerprint data is the fingerprint number or the fingerprint outline and the fingerprint data accounts for more than 80 percent, namely the fingerprint number acquired by the fingerprint data acquisition device exceeds 80 percent or the integrity of the fingerprint exceeds 80 percent, selecting at least one measuring point in a data acquisition area of the fingerprint data acquisition device at intervals of a first set time, acquiring the change times of the fingerprint data on the measuring point in a second set time, and calculating the corresponding heart rhythm value according to the change times.
In the embodiment of the invention, at least one measuring point is selected at intervals of a first set time instead of repeatedly detecting the same measuring point, so that the heart rhythm is calculated through the change times of the fingerprint data acquired at different measuring points, and the accuracy of a detection result is improved.
The calculation method for calculating the corresponding cardiac rhythm value through the change times comprises the following steps: heart rate value= (number of changes/second set time) (1 minute/second set time).
Preferably, when the calculated heart rate value remains within the error range for the error confirmation time, the calculated heart rate value may be output as a result for display to the user. Further, for better convenience to the user, the mobile terminal 100 will also store the last detection result, so that the user can check before the next detection, and at the same time, can compare the two detection results, so that the user can evaluate the situation of the mobile terminal.
In a specific example, the first setting time and the second setting time may be set to 3s, the error confirmation time may be set to 10s, and the error range may be ±5%. That is, when the calculation results of two consecutive times are within the error range, the detection result can be output and displayed to the user.
Preferably, when a plurality of measurement points are selected at intervals of the first set time, the change times of a plurality of fingerprint data corresponding to a plurality of measurement points in the second set time are obtained, a plurality of corresponding cardiac rhythm values are calculated according to the change times, and an average cardiac rhythm value is obtained by averaging the cardiac rhythm values.
Wherein a plurality of said heart rhythm values calculated prior to averaging should be within an error range; and when calculating the heart rhythm value according to the change times corresponding to the plurality of measuring points, averaging the plurality of heart rhythm values to obtain an average heart rhythm value as a result and outputting the average heart rhythm value.
Further, to ensure the accuracy of the change times acquisition result in the second set time, a timing acquisition may be adopted. In order to avoid missing the number of changes, the timing duration should be small enough, for example, 100ms, that is, the number of changes is acquired every 100ms, so as to determine the total number of changes in the second set time.
The method provided by the embodiment of the invention obtains fingerprint data through the fingerprint data acquisition device and calculates the ratio of the fingerprint data; when the ratio of the fingerprint data exceeds a set threshold, at least one measuring point is selected in a data acquisition area of the fingerprint data acquisition device at intervals of a first set time, the change times of the fingerprint data on the measuring point in a second set time are obtained, the corresponding heart rhythm value is calculated through the change times, and the last detection result can be stored so as to be convenient to check before next detection. Therefore, the method provided by the embodiment of the invention enables the user to simply and rapidly detect the heart rhythm through the mobile terminal, know the heart rhythm condition in time and store the detection result, thereby improving the user experience. And because fingerprint identification and fingerprint detection have little influence on users, the heart rhythm detection method provided by the embodiment of the invention realizes that the influence on users is reduced to be extremely low while detecting heart rhythms.
In order to better implement the above-mentioned method for detecting a heart rhythm, the embodiment of the present invention will be further described from the perspective of a heart rhythm detection device, where the heart rhythm detection device may be implemented as an independent entity, or may be integrated into the mobile terminal 100 provided by the embodiment of the present invention, and the mobile terminal 100 may include a mobile phone, a tablet computer, and so on.
