[0060] According to the above embodiment, in a specific embodiment, the above interferential electrical therapy device calibration test device further includes: an oscilloscope 15;

[0061] The oscilloscope displays the voltage waveform signal output by the voltage acquisition circuit and the current waveform signal output by the current acquisition circuit; the host computer 11 is connected to the oscilloscope via a universal serial bus;

[0062] The host computer 11 receives the voltage waveform signal and the current waveform signal sent by the oscilloscope, determines the voltage calibration offset according to the voltage waveform signal and the self-test voltage initial value, and determines the current calibration offset according to the current waveform signal and the self-test current initial value.

[0063] Figure 2 A schematic diagram of a transformer provided in an embodiment of the present application is shown in FIG. Figure 2As shown, T1 and T2 are used as isolation devices, and the microcontroller sends the adjustment amount to the interference circuit board 12, and controls the output waveform amplitude value through the pulse width modulation (PWM) output signal. Due to the difference in the parameters of the electronic components used in the entire circuit, especially the transformer, the maximum voltage amplitude of each output is different under the same adjustment amount, which may cause the voltage and current accuracy to not meet the requirements. An oscilloscope is introduced to compare the self-test initial value with the oscilloscope measurement value, and the host computer 11 software automatically reads it through the Universal Serial Bus (USB) port without manual participation. Through the calibration formula x'=x+b, x is the self-test initial adjustment amount of the functional component 13 to be tested, x' is the calibrated adjustment amount, and b is the calibration offset; if the amplitude measured by the oscilloscope is inconsistent with the preset standard amplitude, the host computer 11 software automatically calculates the required b value to adjust the initial adjustment amount x to make it equal to x'.

[0064] The oscilloscope captures and displays the output waveforms of the voltage acquisition circuit and the current acquisition circuit in real time. Oscilloscopes with different bandwidths and sampling rates can be selected according to test requirements.

[0065] Universal Serial Bus Connection The host computer 11 is connected to the oscilloscope via a universal serial bus such as USB to achieve high-speed data transmission. Specifically, other high-speed data transmission technologies such as Ethernet and wireless network communication technology (Wi-Fi) can be used.

[0066] The oscilloscope captures the real-time waveform signals of the voltage and current acquisition circuits. The captured waveform signals are automatically transmitted to the host computer 11 via the universal serial bus. The host computer 11 software analyzes the received voltage and current waveform signals and extracts key parameters such as amplitude, frequency, phase, etc. For the voltage signal, the host computer 11 software compares the voltage waveform signal measured by the oscilloscope with the initial value of the self-test voltage and calculates the voltage calibration offset. For the current signal, the host computer 11 software performs a similar comparison and calculation process to determine the current calibration offset. Calibration signal generation: The host computer 11 software generates a calibration signal based on the calculated calibration offset to adjust the output of the voltage and current acquisition circuit to match the expected standard value. The intuitive waveform display helps users better understand the test process and results.

[0070] The calibration pressure collector provides accurate reference pressure values ​​for calibrating the pressure collection circuit in the system. Pressure sensors with different accuracy and ranges can be selected and customized according to test requirements and environmental conditions.

[0071] The host computer 11 receives and compares the reference air pressure with the detected air pressure, and calculates the calibration air pressure value. The host computer 11 can use different data processing algorithms, including but not limited to linear regression, machine learning and other methods to improve the calibration accuracy. The air pressure acquisition circuit detects the air pressure state in the interferential electrical therapy device.

[0072] In addition to voltage and current, the system can now calibrate air pressure, ensuring more comprehensive verification of device performance. By comparing the reference pressure and the test pressure, the system can ensure the consistency and accuracy of the air pressure readings.

Accurate air pressure measurement helps maintain the stable air pressure environment required during treatment. Calibration ensures that the air pressure is within a safe range, reducing the risk of treatment.

[0074] According to the above embodiment, in a specific embodiment, the functional component 13 to be tested further includes: a vacuum pump, an air inlet valve, a drain valve, a heating plate, and an ultraviolet lamp;

[0075] The host computer 11 sends start signals and shutdown signals of the vacuum pump, air intake valve, drain valve, heating plate, temperature sensor, ultraviolet lamp, and position sensor to the interference circuit board 12 in sequence; the interference circuit board controls the corresponding functional component to be tested 13 according to the start signal and the shutdown signal; the test circuit board 14 collects the power port voltage of the corresponding functional component to be tested 13 and sends it to the host computer 11; the host computer 11 determines whether the corresponding functional component to be tested 13 is functioning normally according to the power port voltage.

Depending on the detection requirements of the component position, different sensor types are selected, such as photoelectric sensors, magnetic sensors or proximity sensors.

[0089] The host computer 11 sends a switch signal to the position sensor to simulate the operation or test the response of the sensor. The response signal sent by the position sensor is received, and the sensor is judged whether it is working normally according to the signal. After receiving the switch signal from the host computer 11, the position sensor should send a corresponding response signal to indicate the position state it detects.

[0090] The type and configuration of the position sensor can be customized according to different mechanical components and operating environments.

[0105] Correspondingly, a calibration signal is obtained according to the output state signal, including:

[0106] Receive voltage waveform signals and current waveform signals sent by an oscilloscope;

[0107] Determine a voltage calibration offset according to a voltage waveform signal and an initial value of a self-test voltage;

[0108] The current calibration offset is determined according to the current waveform signal and the initial value of the self-test current.

[0109] An oscilloscope is used to automatically measure the output waveform signals of the voltage acquisition circuit and the current acquisition circuit, and the measured values ​​are transmitted to the host computer 11 through the USB interface without human intervention; the software of the host computer 11 receives and stores the waveform signal value measured by the oscilloscope, and compares the value with the self-test initial value of the functional component to be tested 13; the calibration formula x'=x+b is applied, wherein x is the self-test initial adjustment amount of the functional component to be tested 13, x' is the adjustment amount after calibration, and b is the calibration offset; if the amplitude measured by the oscilloscope is inconsistent with the preset standard amplitude, the software of the host computer 11 automatically calculates the required b value to adjust the initial adjustment amount x so that it is equal to x'.

[0110] The calculated calibration offset b is saved in the internal Flash memory of the host computer 11 or the interference circuit board 12 to achieve non-volatile storage.

[0111] According to the above embodiment, in a specific embodiment, the interference electrotherapy device calibration test method, the functional component 13 to be tested also includes: a vacuum pump, an air inlet valve, a drain valve, a heating plate, and an ultraviolet lamp;

[0113] Sending start signals and shutdown signals of a vacuum pump, an air inlet valve, a drain valve, a heater, a temperature sensor, an ultraviolet lamp, and a position sensor to the interference circuit board 12 in sequence, so that the interference circuit board controls the corresponding functional component to be tested 13 according to the start signals and the shutdown signals;

[0114] The receiving test circuit board 14 collects the power port voltage of the corresponding functional component to be tested 13;

[0115] Whether the corresponding functional component to be tested 13 is started and shut down normally is determined according to the power port voltage.

[0116] The host computer 11 sends a start and a stop signal to the interference circuit board 12 to activate or shut down the functional component to be tested 13. The interference circuit board 12 receives the signal and controls the corresponding functional component to be tested 13 to work.

[0117] The air intake valve, drain valve, heating plate, and ultraviolet lamp belong to the same type of testing method. They are all devices that can work by providing voltage. These devices will be connected to the test circuit board 14. When the upper computer 11 sends a start command, the circuit board to be tested will turn on the corresponding device after receiving the command. The test circuit board 14 simultaneously collects the voltage of the power port of each device and sends it to the upper computer 11. The upper computer 11 compares the issued open / close command with the uploaded voltage / no voltage to determine whether the test has passed or not.
