[0032] The human body state monitoring device described in this embodiment can realize efficient monitoring of various physiological indicators of the human body by integrating data acquisition, amplification, processing and transmission modules, thereby providing users with accurate, efficient and convenient human body state monitoring services.

[0033] In another exemplary embodiment, Figure 2As shown, the data processing module 300 includes a main controller, and the main controller adopts an STM32F103C8T6 chip, for example. The main controller is respectively connected to a first branch, a second branch and a third branch, wherein the first branch includes a first capacitor C1, a second capacitor C2, a crystal oscillator Y and an inductor L, a first end of the crystal oscillator Y and a clock input pin (OSC_IN / PD0) of the main controller are connected to form a first node N1, a second end of the crystal oscillator Y and a clock output pin (OSC_OUT / PD1) of the main controller are connected to form a second node N2, a first end of the first capacitor C1 is connected to the first node N1, a second end of the first capacitor C1 is connected to the first ground terminal GND1 to form a third node N3, a first end of the second capacitor C2 is connected to the second node N2, a second end of the second capacitor C2 is connected to the third node N3, and the inductor L and the crystal oscillator Y are connected in parallel.

[0034] The second branch includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a third capacitor C3 and a fourth capacitor C4, wherein the first end of the second resistor R2 is connected to the boot mode control pin (BOOT0) of the main controller to form a fourth node N4, the second end of the second resistor R2 is connected to the third node N3 through the first resistor R1, the first end of the fourth resistor R4 is connected to the fourth node N4, the second end of the fourth resistor R4 is connected to a 3.3V power supply through the third resistor, the first end of the fifth resistor R5 is connected to the 3.3V power supply, the second end of the fifth resistor R5 is connected to the analog power pin (VDDA) of the main controller to form a fifth node N5 and a sixth node N6 in sequence, the first end of the third capacitor C3 is connected to the fifth node N5, the first end of the fourth capacitor C4 is connected to the sixth node N6, the second end of the third capacitor C3 and the second end of the fourth capacitor C4 are connected to the second ground terminal GND2.

[0035] The third branch includes a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10 and a first light-emitting diode D1, wherein a first end of the sixth resistor R6 is connected to a first multi-function pin (PB2 / BOOT1) of the main controller to form a seventh node N7, a second end of the sixth resistor R6 is connected to a 3.3V power supply via the seventh resistor R7, a first end of the eighth resistor R8 is connected to the seventh node N7, a second end of the eighth resistor R8 is connected to a third ground terminal GND3 via the ninth resistor R9, a first end of the tenth resistor R10 is connected to a second multi-function pin (PC13-TAMPER-RTC) of the main controller, a second end of the tenth resistor R10 is connected to an anode of the first light-emitting diode D1, and a cathode of the first light-emitting diode D1 is connected to the third ground terminal GND3.

[0036] In this embodiment, in the first branch, the crystal oscillator Y is used to generate an accurate clock signal, and the first capacitor C1 and the second capacitor C2 are used to stabilize the operating frequency of the crystal oscillator Y, and also play a filtering role to ensure that the clock signal output by the crystal oscillator Y is pure and free of noise. The inductor L is connected in parallel with the crystal oscillator Y, so that the crystal oscillator Y can generate a stable oscillation frequency. In the second branch, the first end of the second resistor R2 is connected to the boot mode control pin (BOOT0) of the main controller, and is connected to the third node N3 through the first resistor R1. In this way, through the voltage division effect of the first resistor R1 and the second resistor R2, the level state of the boot mode control pin (BOOT0) can be determined, and then the boot mode of the main controller can be determined, such as booting from flash memory, booting from system memory, etc., which is convenient for selecting the most suitable boot mode in different application scenarios. The fourth resistor R4 and the third resistor R3 form a voltage divider circuit, which can ensure that the voltage on the analog power pin (VDDA) is within a safe range. The third capacitor C3 and the fourth capacitor C4 are connected in parallel to play the role of power supply decoupling, which can help filter out transient noise on the power line, thereby ensuring the reliability of the main controller and other analog circuit components. In the third branch, one end of the sixth resistor R6 is connected to the first multi-function pin (PB2 / BOOT1) of the main controller, and the other end of the sixth resistor R6 is connected to the 3.3V power supply through the seventh resistor R7, so that a pull-up circuit is formed, and when the first multi-function pin (PB2 / BOOT1) is not driven or in a high-impedance state, the pull-up circuit can ensure that the pin remains in a high-level state. When the first multi-function pin (PB2 / BOOT1) is set to output a low level, if the pin is connected to a load or an external device that needs to be controlled, the eighth resistor R8 and the ninth resistor R9 can play the role of current limiting, preventing excessive current from flowing directly from the 3.3V power supply to the ground, thereby protecting the circuit from damage. The first end of the tenth resistor R10 is connected to the second multi-function pin (PC13-TAMPER-RTC) of the main controller, and the other end of the tenth resistor R10 is connected to the anode of the first light-emitting diode D1. When the second multi-function pin (PC13-TAMPER-RTC) is set to output a low level, a current path from the 3.3V power supply to the ground is formed, so that the first light-emitting diode D1 is turned on and emits light. The third branch realizes the status indication function through a simple combination of a resistor and a light-emitting diode, thereby enhancing the usability and user experience of the detection device.

[0037] In another exemplary embodiment, the data acquisition module 100 includes: a gas sensor, a grip sensor, a critical strobe detection module and a reaction detection module, wherein the gas sensor is connected to the PA1 pin or the PA2 pin (both are GPIO pins) in the Port A group of the main controller, and is used to collect human exhalation data, such as end-tidal carbon dioxide concentration, vital capacity, and breath alcohol content. The grip sensor is connected to the PA3 pin (GPIO pin) in the Port A group of the main controller, and is used to collect human grip data; the critical strobe detection module is connected to the PA11 pin in the Port A group of the main controller or the PB14 pin in the Port B group (both are GPIO pins), and is used to collect human reaction data to light source changes; the reaction detection module is connected to the PB5, PB6, PB7 and PB8 (all are GPIO pins) in the Port B group of the main controller, and is used to collect human reaction data to specific stimuli (such as lights of different colors).

[0038] In this embodiment, the gas sensor monitors the changes in chemical components in the exhaled gas of the human body, and converts it into an electrical signal and feeds it back to the data processing module 300. Similarly, the grip sensor can convert the grip force of the human body into an electrical signal and feed it back to the data processing module 300. The critical strobe detection module can detect the sensitivity of the human body to the change of the light source. When the light source is stable, the capacitor in the critical strobe detection module will continue to charge to saturation; when the light source flickers, the capacitor in the critical strobe detection module will alternately charge and discharge in each cycle, thereby causing the current in the circuit to change, and then the individual's reaction to the change of the light source can be evaluated by detecting these changes. The reaction detection module can be used to test the reaction time of the human body to a specific stimulus (such as light of different colors). The reaction detection module usually includes one or more buttons. When the subject sees a specific stimulus, the button is pressed. The module records the time interval from the appearance of the stimulus to the button being pressed, so as to measure the reaction speed.

[0039] In another exemplary embodiment, Figure 3As shown, the critical strobe detection module includes: a strobe detection interface, a first switch S1, a second switch S2, a thirteenth capacitor C13, a fourteenth capacitor C14, a second light-emitting diode D2 and a third light-emitting diode D3, wherein the strobe detection interface includes a first detection input pin (pin 3), a second detection input pin (pin 2), a positive voltage input pin (pin 5), a negative voltage input pin (pin 4) and a ground pin (pin 1), and the first detection input pin (pin 3), the second detection input pin (pin 2), the positive voltage input pin (pin 5), and the negative voltage input pin (pin 4) are respectively connected to the Port of the main controller The PA11 pin in group A and the PB13 pin, PB14 pin and PB15 pin (all GPIO pins) in group PortB, the first end of the first switch S1 is connected to the first detection input pin (pin 3) of the strobe detection interface to form a fifteenth node N15, the second end of the first switch S1 is connected to the eleventh ground terminal GND11 to form a seventeenth node N17, the first end of the thirteenth capacitor C13 is connected to the fifteenth node N15, the second end of the thirteenth capacitor C13 is connected to the seventeenth node N17, the first switch S1 and the thirteenth capacitor C13 are connected in parallel to form a first strobe detection branch; the first end of the second switch S2 is connected to the second detection input pin (pin 2) of the strobe detection interface to form a sixteenth node N16, the first end of the fourteenth capacitor C14 is connected to the sixteenth node Point N16, the second end of the second switch S2 and the second end of the fourteenth capacitor C14 are connected to the seventeenth node N17, and the second switch S2 and the fourteenth capacitor C14 are connected in parallel to form a second strobe detection branch; the anode of the second light-emitting diode D2 is connected to the positive voltage input pin (pin 5) of the strobe detection interface to form a thirteenth node N13, the cathode of the second light-emitting diode D2 is connected to the negative voltage input pin (pin 4) of the strobe detection interface to form a fourteenth node N14, the anode of the third light-emitting diode D3 is connected to the thirteenth node N13, the cathode of the third light-emitting diode D3 is connected to the fourteenth node N14, the second light-emitting diode D2 and the third light-emitting diode D3 are connected in parallel to form a light-emitting branch, and the ground pin (pin 1) of the strobe detection interface is connected to the tenth ground terminal GND10.

[0040] In this embodiment, the first strobe detection branch and the second strobe detection branch are both grounded, so that a closed loop is formed. When the first switch S1 or the second switch S2 is closed, the thirteenth capacitor C13 or the fourteenth capacitor C14 starts to charge. If the light source is stable (i.e., there is no strobe), the thirteenth capacitor C13 or the fourteenth capacitor C14 will continue to charge until a steady-state value is reached, at which time the voltage across the thirteenth capacitor C13 or the fourteenth capacitor C14 no longer changes. If the light source has a stroboscopic phenomenon (i.e., there is a periodic change in light intensity), this phenomenon will cause the current and voltage in the circuit to fluctuate accordingly. When the light source intensity weakens and becomes darker, the thirteenth capacitor C13 or the fourteenth capacitor C14 starts to discharge; when the light source intensity increases and becomes brighter again, the thirteenth capacitor C13 or the fourteenth capacitor C14 starts to charge again. Therefore, the voltage on the thirteenth capacitor C13 or the fourteenth capacitor C14 will be periodically charged and discharged as the brightness of the light source changes. The stroboscopic detection module can simultaneously detect whether there is stroboscopic phenomenon in two different light sources by setting two detection branches, thereby enhancing the versatility and adaptability of the human body state detection device. In addition, since the two detection branches can work synchronously, there is no need to switch to detect a single light source in turn, thereby reducing the detection time and improving the detection efficiency. The second light emitting diode D2 and the third light emitting diode D3 are used as indicator lights to visualize the detection results. If stroboscopic is detected, the second light emitting diode D2 and the third light emitting diode D3 will flash in a certain pattern as visual feedback to inform the user of the detection results. In addition, the ground pin (pin 1) of the stroboscopic detection interface is connected to the tenth ground terminal GND10, which helps to stabilize the working state of the entire circuit and helps to prevent interference signals from affecting the detection accuracy.

[0041] In summary, the stroboscopic detection module senses whether the light source has stroboscopic phenomenon by monitoring the detection branch composed of switches and capacitors. If the light source flickers, the current change in the circuit will cause the light-emitting diode to flicker or send a signal, thereby realizing the detection of stroboscopic phenomenon.

[0043] In this embodiment, the reaction detection module measures the reaction time of an individual to a specific stimulus (such as light) by detecting the time when a button is pressed. Its working principle is described as follows: when a user presses any button, the switch connected thereto (such as S4, S5, S6, S7) is closed to form a path from the button detection pin to the ground terminal. When switches S4, S5, S6, S7 are closed, the capacitors connected thereto (such as C20, C21, C22, C23) begin to charge through this path. The time for capacitor charging depends on the time length from when the button is pressed to when it is released. The changes caused by capacitor charging can be captured and transmitted to the main controller for processing through the circuit. The main controller calculates the reaction time of the user from seeing the stimulus to pressing the button by detecting the time of the capacitor charging process.

Specifically, when the third switch S3 is closed (i.e., the reset key RESET is pressed), the nineteenth node N19 is pulled down to the ground level through the third switch S3, and the nineteenth capacitor C19 starts to charge.
