Referring to fig. 4, fig. 4 is a flowchart of a method for monitoring human body signs according to an embodiment of the present application, as shown in fig. 4, the method for monitoring human body signs includes:
s41, respectively acquiring a first human body sign signal acquired by the first sensor and a second human body sign signal acquired by the second sensor;
the first sensor 321 and the second sensor 322 collect the human body sign signals of the user 10, and the sampling frequencies can be the same and are all 100HZ. The first sensor 321 and the second sensor 322 may be the same sensor or may be different sensors.
In some embodiments, the first sensor 321 has a higher sensitivity than the second sensor 322, and the area where data is collected is wider, and accordingly, the first sensor 321 is more susceptible to interference from other signals, and the area where data is collected by the second sensor 322 is narrower, and is not susceptible to interference from other signals. For example: in the above application scenario, if the first sensor 321 and the second sensor 322 are disposed under the user a, the first sensor 321 can be used to collect the human body sign signal of the user a, where the user a is a detected user, and the first sensor 321 is easy to capture the human body sign signal of the user B, so as to affect the human body sign signal of the user a, the collected signal includes the human body sign information of the user a and the human body sign information of the user B with stronger interference, and the second sensor 322 is difficult to capture the human body sign signal of the user B, and the collected signal includes the human body sign information of the user a and the human body sign information of the user B with weaker interference. Therefore, the embodiment of the application adopts a mode of two sensors to exert complementary advantages.
In some embodiments, the human body physical sign monitoring device 32 is used for sleep monitoring, so that the first sensor 321 and the second sensor 322 can be piezoelectric sensors, the sleeping monitoring product based on the piezoelectric sensors can record the physical activity, the respiratory activity, the heart rate and other conditions of the tested person without pasting electrodes on the body surface, and the sleep apnea syndrome can be diagnosed, so that the sleep monitoring method is an electrodeless and non-load sleep monitoring method. In the embodiment of the present application, the first sensor 321 is a piezoelectric thin film sensor, and the second sensor 322 is a piezoelectric cable sensor.
In other embodiments, the first sensor 321 and the second sensor 322 may be other types of sensors for acquiring physical sign information, including but not limited to micro-motion sensors such as acceleration sensors, gyroscopes, and the like.
S42, performing correlation operation on the first human body sign signal and the second human body sign signal to obtain a third human body sign signal;
wherein the correlation operation includes cross correlation or auto correlation, and the definition of a correlation function:
let x (n) and y (n) be two energy-limited deterministic signals whose cross-correlation function is:
the equation indicates that the value at time m is equal to the result of multiplying and then adding two sequences after x (n) is fixed and y (n) is shifted left by m sample units. It can be appreciated that when x (n) and y (n) are the same signal, i.e., x (n) =y (n), the correlation function Rxx (m) (or abbreviated as R (m)) is an autocorrelation function:
the autocorrelation function R (m) reflects the similarity of the signal x (n) and x (n+m) after a delay itself.
The correlation function has two properties: first, the correlation function of the periodic signal is still the same frequency periodic signal, and second, the two non-same frequency periodic signals are not correlated with each other. That is, after the correlation operation is performed on the signal x (n) and the signal y (n+m), the periodic signal (the sign signal) is enhanced, but the same-frequency periodic signal (the interference signal) is weakened, so that the influence of the interference signal is suppressed, and meanwhile, the quality of the effective human sign signal is improved. The embodiment of the application utilizes two properties of a correlation function to process and analyze a first human body sign signal and a second human body sign signal, wherein the first human body sign signal and the second human body sign signal are mainly sign signals of a user A, and the first human body sign signal and the second human body sign signal are subjected to correlation operation to obtain a third human body sign signal R (m).
Referring to fig. 5, the S1 curve is a first human body sign signal, the S2 curve is a second human body sign signal, and the S3 curve is a third human body sign signal, in which the period of the user a sign signal is enhanced, the peak value is more obvious, and the period of the interference signal (such as the sign signal of the user B) is enhanced relatively weaker, so that the signal quality of the third human body sign signal is better, the signal-to-noise ratio is higher, and the interference of the noise signal is reduced.
S43, acquiring the human body sign information according to the third human body sign signal.
And acquiring human body sign information according to the third human body sign signals and the calculation modes of the related human body signs. In some embodiments, the human body sign information comprises heart rate information, a peak time interval in the third human body sign signal is obtained, and the heart rate information is obtained according to the peak time interval. In some embodiments, the vital sign information includes respiratory rate information, a third vital sign signal that is primarily a respiratory rate signal is acquired in the same manner, and the respiratory rate information is acquired based on a peak time interval in the third vital sign signal. Before the first human body sign signal and the second human body sign signal are subjected to correlation operation, the first human body sign signal and the second human body sign signal which are mainly heart rate signals, and the first human body sign signal and the second human body sign signal which are mainly respiratory rate are obtained through filtering treatment, and then subsequent treatment is carried out.
In summary, since the sensitivity of the first sensor is higher, the interference signal in the acquired first human body sign signal is stronger, the sensitivity of the second sensor is lower, the interference signal in the acquired second human body sign signal is weaker, that is, the first human body sign signal includes the sign information of the detected user and the sign information or other noise signals of other users with stronger interference, the second human body sign signal includes the sign information of the detected user and the sign information or other noise signals of other users with weaker interference, therefore, the human body sign monitoring device can perform correlation operation on the first human body sign signal and the second human body sign signal through the correlation function, the periodic human body sign signals of the detected user in the two signals can be enhanced, other aperiodic interference signals can be suppressed, and further, the signal to noise ratio of the third human body sign signal is improved, finally, the influence of the noise signals is reduced, the interference signals can be acquired, and the human body sign information of the detected user can be more accurately acquired.

The signal processing circuit 324 is configured to amplify and filter the first and second human sign signals, and the amplified signals are more easily processed by the controller 323, and can be filtered at different frequencies according to the required human sign information, for example, the heartbeat information is about 10HZ, and the respiration information is about 0.4 HZ.
In some embodiments, the human body sign monitoring device 32 further includes a wireless module 325, where the wireless module 325 is communicatively connected to the controller 323, and is configured to communicate data with the mobile terminal 31 and/or the cloud 33.
