Detailed Description
The present invention will be further specifically described with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, a healthy fingerprint lock comprises a lock body 1, a fingerprint module 2, a vital sign checking module 3, a display module 4, an alarm module 5, and a power supply unit 6, wherein the fingerprint module 2, the vital sign detecting module 3, the display module 4, the alarm module 5, and the power supply unit 6 are integrated in the lock body; fingerprint module 2 is connected with display module 4, and vital sign detection module 3 is connected with display module 4, and power supply unit 6 supplies power for whole device. The fingerprint module 2 is preferably an optical fingerprint module, and is used for completing fingerprint acquisition and fingerprint identification. The vital sign detection module 3 comprises a reflection type heart rate acquisition module 8, a data transmission module 9 and a data storage processing module 10, and is used for measuring the blood oxygen saturation, the heart rate and the blood pressure.
The reflection type heart rate acquisition module 8 acquires human health information data, the data are transmitted to the data storage processing module 10 through the data transmission module 9, and the data storage processing module 10 analyzes and compares the acquired data to provide suggestions for a user. When the fingerprint module 2 identifies that the fingerprint is wrong or the fingerprint is correct but the vital sign is abnormal, an alarm signal is sent out through the alarm module 5. The abnormal condition of the vital sign comprises that the vital sign parameter cannot be detected, the measured vital sign parameter has a larger difference with a calibration value, and the like.
As shown in fig. 3, the reflective heart rate acquisition module 8 includes an 81-infrared detector, a 82-730nm light source, an 83-850nm light source, an 84-photoelectric detector, and an 85-analog-to-digital converter, the infrared detector 81 is connected to the photoelectric detector 84, the photoelectric detector 84 is connected to the analog-to-digital converter 85, and the analog-to-digital converter 85 is connected to the data transmission module 9.

The main principle of measurement with the reflex heart rate acquisition module 8 is based on the modified beer-lambert law, which can be used to convert the acquired light intensity variations into concentration variations of oxyhemoglobin and deoxyhemoglobin. This law is based on the following assumptions: the absorption is uniform throughout the illuminated area and the scattering loss time variation is constant. The attenuation can be calculated by using formula 1, wherein the attenuation is obtained by using light to pass through a known path and then obtaining original light intensity change data according to a detector:
wherein,
is the absorption coefficient (cm-1 mM-1); c is the light absorbing species concentration (mM);
is the incident light intensity;
is the light intensity of the incident light after passing through the medium; l is the average length of the photon migration path in the medium;
is the absorption coefficient of the medium; g is a geometric scattering factor, which is related to the geometry of the medium and can be considered as a constant.
In the biological tissue, the rate of change of the light intensity obtained by the transmission detection mode and the reflection detection mode is the same, the rate of change of the light intensity is represented by W, and a general formula of the change of the light intensity is obtained:
when two beams of light having wavelengths in the near infrared region (e.g., λ 1=660nm and λ 2=850 nm) are selected to probe tissue, considering only the effects of deoxyhemoglobin (Hb) and oxyhemoglobin (HbO2), the absorption coefficients at the two wavelengths can be written as follows in equation (2):
wherein
Is the concentration of oxyhemoglobin;
is the concentration of deoxyhemoglobin;
is the molar absorption coefficient of oxyhemoglobin at an incident light wavelength of 660 nm;
is the molar absorption coefficient of oxyhemoglobin at an incident light wavelength of 850 nm;is the molar absorption coefficient of deoxyhemoglobin at an incident wavelength of 730 nm;
is the molar absorption coefficient of the deoxyhemoglobin when the incident wavelength is 850nm, and can be obtained by adopting a time domain or frequency domain spectral analysis method.
And (3) respectively substituting the two formulas of the formula (3) into the formula (2), and obtaining the following formula according to a double-beam method:
and because the oxygen saturation level (SpO2) is the percentage of the volume of oxygenated hemoglobin bound by oxygen (HbO2) in the blood to the total bindable hemoglobin (Hb) volume, i.e.:
substituting equation (4) into equation (5) yields the formula for blood oxygen saturation:
therefore, the concentration changes of oxyhemoglobin and deoxyhemoglobin can cause the change of the absorption coefficient of light according to the improved beer-Lambert law, the light emitted by the light source of the reflection type heart rate acquisition module is modulated by the changes, the changed light intensity is converted into an electric signal by the photoelectric detector, the electric signal is further converted into a digital signal by the analog-digital converter, and therefore pulse wave data are obtained, and then the blood oxygen saturation can be resolved from the pulse wave data according to a formula; on the other hand, because the pulse waves are caused by the heart beat, the frequency of the pulse waves is consistent with the heart beat frequency, the heart rate can be obtained by calculating the peak value periods of the two pulse waves and taking the reciprocal, and the heart rate change curve of the tested person can be obtained by extracting the frequency of the pulse waves in each period and recording; on the other hand, a second derivative is obtained by comparing the complete pulse waves, the pulse wave propagation time is obtained through the second derivative of the pulse waves, and then the obtained pulse wave propagation time is utilized to calculate the blood pressure values such as the systolic pressure, the diastolic pressure and the like.
Accomplish simple health detection through the fingerprint lock, help improving the security and the functional of fingerprint lock to help the user to know self health when opening the door, save time and convenience can suggest when detecting that user's is healthy to be had a problem and remind, help the prevention of some diseases.
The above embodiments are only routine descriptions of the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and all the changes and modifications made by the technical solutions of the present invention by the professional in the field are within the protection scope of the present invention without departing from the design idea of the present invention.
