Example one

An embodiment of the present application provides a health detection device, please refer to FIG. 1, including:

The detection signal processing circuit 102 is configured to perform signal conversion processing on the bioelectric signal, and transmit the bioelectric signal after the signal conversion processing to the control circuit;

The signal conversion processing may include at least one of the following processing operations: signal conversion, amplification and filtering, noise reduction, and digitization. Specifically, according to the difference of the collected signals, the collected signals also need to undergo corresponding signal conversion processing; for example, if the collected signals are voltage signals for soreness detection, signal filtering, noise reduction, And signal amplification and other processing. If the collected signal is a light reflection signal used for blood oxygen detection, signal conversion, amplification and filtering, noise reduction and digitization are required.

In practical applications, the control circuit 103 may be a Microcontroller Unit (MCU), which is used for data analysis and calculation in the health detection device. Among them, the control circuit 103 in the embodiment of the present application has at least the following two functional modules: a detection state recognition functional module and a health data processing functional module.

In practical applications, according to different detection requirements, the detection state recognition function module also has different implementation methods. The following is an example of blood oxygen detection and soreness detection:

Blood oxygen test

In practical applications, blood oxygen detection mainly realizes the detection of health data such as pulse rate, blood oxygen, and heart rate variability, and then analyzes health indexes such as fatigue index and stress index based on these health data.

In the realization of the function of blood oxygen detection, the detection sensor device used is the blood oxygen detection sensor device.

Specifically, referring to FIG. 2, the blood oxygen detection sensor device 1011 includes: a first light emitting diode 1111, a second light emitting diode 1211, and a photosensitive sensor 1311;

Health data such as blood rate, blood oxygen and heart rate variability, and analyze the health index of the hand skin based on the detection result of the health data.

Specifically, the method for detecting effective contact is: the control circuit samples the light intensity electrical signal N times in the first time period, and obtains the light intensity of the maximum and minimum voltage amplitudes of the light intensity electrical signal. The signal voltage difference value is compared with a first threshold value. If the light signal voltage difference value is greater than or equal to the first threshold value, it is determined that the portion to be detected of the hand skin covers the blood oxygen detection sensor device If the optical signal voltage difference is less than the first threshold, it is determined that the portion of the hand skin to be detected does not cover the blood oxygen detection sensing device; the N is an integer greater than one.

Further, after determining that the part of the hand skin to be detected covers the blood oxygen detection sensor device, the control circuit performs M sampling of the light intensity electrical signal in the second time period, and performs a third The light intensity electrical signal in the time period is analyzed, and if in the third time period, the waveform signal formed by the light intensity electrical signal has at least three peaks, it is determined that the part of the hand skin to be detected Effective contact with the blood oxygen detection sensing device; if at least 3 peaks do not appear in the waveform signal formed by the light intensity electrical signal in the third time period, it is determined that the hand skin The part to be detected is not in effective contact with the blood oxygen detection sensor device. The M is an integer greater than one, and the third time period is the sum of the first time period and the second time period.

Among them, "finger not covering the sensor state" indicates that the user's finger does not cover the blood oxygen detection sensor device, and prompts the user to adjust the placement of the finger.

The soreness detection state recognition module is used to receive the voltage signal after signal conversion processing through the soreness signal processing sub-circuit, and identify whether the hand skin is effective with the soreness detection sensing device according to the voltage signal contact.

Specifically, the method for detecting effective contact is: calculating the equivalent resistance value between the first electrode sheet and the second electrode sheet according to the voltage signal, and if the equivalent resistance value is less than the second threshold, then It is determined that the to-be-detected part of the hand skin is in effective contact with the soreness detection sensor device; if the equivalent resistance value is greater than or equal to the second threshold, it is determined that the to-be-detected part of the hand skin is in contact with The soreness detection sensor device is not in effective contact. Exemplarily, the second threshold may be an infinite resistance value.
