[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0039] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships.

[0040] In one embodiment, Figure 1 As shown, an electric pulse generator system is provided, comprising: a display module 1, a heart rate sensor module 2, a boost module 3, a switch module 4 and a main control module 5. The main control module 5 is communicatively connected with the display module 1, the heart rate sensor module 2, the boost module 3 and the switch module 4.

[0041] Display module 1 is used to obtain the user's acquisition information, obtain display information based on the acquisition information, and display the display information on the screen; wherein the acquisition information includes: heart rate data (heart rate and blood oxygen data) and input information. Specifically, Figure 2 As shown, the display module is an OLED display module. Display module 1 generates display information based on heart rate data and displays the display information on the screen. The display information includes the heart rate threshold and duty cycle. By adjusting the threshold, the heart rate can be discharged below this value. By adjusting the duty (duty cycle) value, the output voltage can be controlled, thereby producing different stimulation sensations.

[0042] The heart rate sensor module 2 is used to obtain heart rate data and send the heart rate data to the main control module 5. Specifically, Figure 3As shown, Heart Rate Sensor Module 2 is a MAX30102 module. It first performs initialization and configuration, then calculates heart rate and blood oxygen levels. Heart Rate Sensor Module 2 is an integrated pulse oximeter and heart rate monitoring module. It includes an internal LED, photodetector, optical components, and low-noise electronics, providing a complete pulse oximeter and heart rate sensor system solution module designed specifically for the requirements of wearable devices. This module maintains a very small solution size without sacrificing optical or electrical performance. Integration into a wearable system requires minimal external hardware components.

[0043] The Heart Rate Sensor Module 2's SpO2 subsystem includes ambient light cancellation (ALC), a continuous-time sigma-delta ADC, and a proprietary discrete-time filter. These features enable the Heart Rate Sensor Module 2 to accurately measure blood oxygen saturation (SpO2) and provide reliable pulse rate readings. ALC is an automatic adjustment technology that eliminates the effects of ambient light, which can interfere with blood oxygen saturation measurements. This helps improve measurement accuracy and reliability, as ambient light can interfere with blood oxygen saturation measurements. The ALC includes an internal track / hold circuit to cancel ambient light and increase the effective dynamic range. The continuous-time sigma-delta ADC converts analog signals into digital signals for subsequent processing and analysis. This ADC offers high precision and low noise, providing high-quality data. The internal ADC is a continuous-time oversampled sigma-delta converter with 18-bit resolution. The ADC sampling rate is 10.24MHz, and the ADC output data rate can range from 50 samples per second (sps) to 3200 sps.

[0044] A proprietary discrete-time filter is used to remove noise and extract useful signals. This filter can effectively process a variety of complex signals, resulting in more accurate measurements. There is also a temperature sensor on the heart rate sensor module 2 for calibrating the temperature dependence of the SpO2 subsystem. The device includes a proximity function that saves power and reduces visible light emissions when the user's finger is not on the sensor. The SpO2 and HR modes of the heart rate sensor module 2 are used to measure pulse oximetry (SpO2) and heart rate (HR) signals. By using red and infrared light measurements, the sensor can calculate blood oxygen saturation and heart rate.

[0045] Pulse and Heart Rate Measurement Principle: The heart rate sensor module 2 features a pair of high-intensity LEDs, one emitting red light (wavelength 660nm) and the other emitting infrared light (wavelength 880nm), along with a photodetector. Measurements are performed using photoplethysmography (PPG). Red and infrared light penetrate human tissue, and a photodetector measures the amount of reflected light. The photodetector detects pulse and measures blood oxygen saturation by exploiting the difference in light transmittance caused by vascular pulsation. (The optical signal is converted into an electrical signal, amplified, and output.) The DC signal reflects venous blood, tissue, bone, and muscle, while the AC signal reflects arterial blood. Heart rate and blood oxygen saturation can be calculated based on these two signals. Oxygenated hemoglobin (HbO2) absorbs infrared light; the redder the blood, the more infrared light it absorbs. When the heart beats, blood is pumped in and out, causing the intensity of reflected light to change (and the amount of infrared light absorbed to vary). Photodetectors receive the light that passes through the skin and convert it into electrical signals, producing a varying waveform. By measuring the changes in these electrical signals, filtering them, and counting the number of peaks over a period of time, the heart rate can be calculated.

[0046] For example: In the time T seconds, there are N peaks:

[0047] Heart rate = (N / T) * 60 = 60N / T (unit: times / min)

[0048] Among them, Heart rate represents heart rate, T represents time in T seconds, and N represents N peaks.

[0049] Blood contains oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin (Hb), which have different absorption spectra. Deoxygenated hemoglobin (Hb) absorbs more red light, while oxygenated hemoglobin (HbO2) absorbs more infrared light. The heart rate sensor module 2 emits both red and infrared light simultaneously. A photodetector measures the amount of reflected light, determining the amount of red and infrared light absorbed. This infers the ratio of oxygenated hemoglobin (HbO2) to deoxygenated hemoglobin (Hb), and thus calculates the oxygen content in blood pressure.

[0050] SpO2=-45.060*R*R+30.354*R+94.845.

[0051]

[0052] Here, R represents the ratio of the red and infrared light signals. Acred represents the AC component of the red light signal, which is the portion of the signal that varies after the DC component is removed from the filtered red light signal. This portion of the signal is correlated with the heartbeat. Dcred represents the DC component of the red light signal, which is the average value of the filtered red light signal. It represents the baseline signal strength and does not vary with the heartbeat. Acired represents the AC component of the infrared light signal, which is the portion of the signal that varies after the DC component is removed from the filtered infrared light signal. This portion of the signal is also correlated with the heartbeat. Dcired represents the DC component of the infrared light signal, which is the average value of the filtered infrared light signal. It represents the baseline signal strength and does not vary with the heartbeat. SpO2 represents blood oxygen saturation, which is calculated by measuring the ratio of the red and infrared light signals. SpO2 is the percentage of oxygen content in the blood and is an important physiological indicator.

[0053] The boost module 3 is used to increase the voltage generated by the main control module 5 to the stimulation voltage, that is, to boost the 5V voltage provided by the main control module 5 to more than 30 volts to provide a large voltage. Figure 4 As shown, boost module 3 uses the SX1308 as the main control chip. The SX1308 is a fixed-frequency, current-mode boost converter in a SOT23-6 package. Its high operating frequency of 1.2MHz allows for smaller external inductor and capacitor sizes. A built-in soft-start function reduces startup inrush current. The SX1308 automatically switches to PFM mode under light load. The SX1308 includes input undervoltage lockout, current limiting, and overtemperature protection. The small package saves additional PCB space. Boost module 3 integrates an 80mQ power MOSFET with a wide input voltage range of 2V to 24V. It operates at a fixed frequency of 1.2MHz, has an internal 4A current limit, and supports an adjustable output voltage up to 28V. Boost module 3 features internal compensation, simplifying the external component count. Boost module 3 also features automatic PFM mode and is packaged in a SOT23-6 package. Boost module 3 achieves an efficiency of up to 97%.

[0054] The switch module 4 is used to control the discharge of the main control module 5 to adjust the heart rate. Figure 5 As shown, switch module 4 is a MOSFET switch module. It offers advantages such as fast switching speed, high input impedance, and good thermal stability. In high-power applications, these advantages enable field-effect transistors (MOSFETs) to respond quickly to signals, reduce energy loss, and improve device efficiency. Its primary function is to control the PWM signal through a microcontroller, thereby controlling the voltage at its input.

[0055] The main control module 5 is used to receive the acquired information, process the acquired information, and generate an output signal. The main control module 5 includes a main chip, a power supply circuit unit, a clock circuit unit, a reset circuit unit, a startup circuit unit, a program download circuit unit, and an expansion circuit unit. The main chip, the power supply circuit unit, the clock circuit unit, the reset circuit unit, the startup circuit unit, the program download circuit unit, and the expansion circuit unit are communicatively connected.

[0056] Main chip, such as Figure 6 As shown, it receives acquired information, processes it, and generates output signals. Specifically, the main chip is an STM32. The main chip requires a 3.3V voltage input. An internal low-dropout regulator (LDO) stabilizes the external voltage to the required core voltage. External decoupling capacitors also filter out power supply noise, ensuring power supply stability. The clock circuit then provides clock signals to the various modules on the chip. The main chip has multiple clock sources, including an internal oscillator (HSI), an external crystal oscillator (HSE), and low-speed clocks (LSI and LSE). Upon system power-up, the main chip selects the internal clock source (HSI) by default, but the external crystal oscillator (HSE) can also be selected as the system clock through software configuration. Clock signals drive the CPU, peripherals, and timers, ensuring that these modules operate at their specified frequencies.

[0057] Power supply circuit unit, such as Figure 7 As shown, it is used to receive external power supply and provide power to the electric pulse generating system; the clock circuit unit, such as Figure 8 As shown, it is used to provide clock signals for the display module 1, the heart rate sensor module 2, the boost module 3 and the switch module 4; the reset circuit unit, such as Figure 9 As shown, it is used to initialize the main chip to the default state; start the circuit unit, such as Figure 10 As shown, it is used to determine the startup memory of the main chip. Specifically, the startup circuit unit is a BOOT startup circuit unit. The program download circuit unit, such as Figure 11 As shown, it is used to download the binary file of the compiled program to ensure the operation of the main chip; the expansion circuit unit is used to connect external devices and provide a connection interface for the external devices.

[0058] After the system powers on, the power supply circuitry first operates to ensure a stable power supply voltage for the main chip and all peripherals. The reset circuit unit initializes the main chip to its default state, and then the boot circuit unit determines which memory the main chip boots from. The reset circuit unit resets the main chip to its initial state when the main chip powers on or an external reset signal is triggered. The reset circuit unit resets the CPU registers, clears RAM data, and initiates the initialization process. Power-on reset (POR) and low-voltage detection reset (LVD) are common mechanisms within the reset circuit unit to ensure that the system does not behave abnormally during power instability. The boot circuit unit determines the boot mode of the main chip after power-on or reset. The main chip typically has three boot options: main flash memory, system memory, or SRAM. The boot mode is determined by the level of the boot circuit unit's pins. The user can select the boot mode by adjusting the level of the boot circuit unit's pins. If necessary, the program download circuit unit is used to download a new program to the flash memory. The program download circuit unit is used to download the user program to the main chip's built-in flash memory. Common download interfaces include SWD (Serial Wire Debug) and JTAG, which connect to a PC via a debugger or programmer. Program downloads are typically performed during the system development and debugging phase to ensure that the program within the main chip can be executed normally. Finally, the expansion circuit unit begins interacting with external devices. The expansion circuit includes connections to external devices such as sensors, communication modules, displays, and keyboards. The main chip communicates and controls these expansion devices through peripheral interfaces such as GPIO, UART, I2C, and SPI. The expansion circuit unit is connected to four external modules. The heart rate sensor module 2 first performs initialization and configuration, then calculates heart rate and blood oxygen levels. The display module 1 then initializes and displays the heart rate and blood oxygen data. Finally, the boost module 3 boosts the microcontroller's 5V voltage to over 30V. The switch module 4 then begins operating, controlling the output voltage of the electrode through the PWM signal from the main control module 5.
