Description

Technical Field

[0001] The invention relates to a tinnitus diagnosis and treatment instrument, and in particular to a method for accurately controlling the current output size of the tinnitus diagnosis and treatment instrument. Background Art

[0002] Tinnitus diagnostic and therapeutic instrument is a medical device used to relieve and treat tinnitus symptoms, which includes an output current function. During the tinnitus treatment process, the tinnitus diagnostic and therapeutic instrument usually needs to output currents of different intensities for electrical stimulation. However, due to the uncertainty of the chip reference current and the error in the current output process, the actual output current value may be inconsistent with the set parameters. The existing calibration method is difficult to achieve high-precision control of the current output, resulting in unstable treatment effects. Therefore, it is particularly necessary to propose a method that can accurately control the current output size. Summary of the invention

[0003] The present invention discloses a method for controlling the current output intensity of a tinnitus diagnosis and treatment instrument, which accurately controls the current output by setting the relationship between the current output parameter and the actual observed current value, establishing and solving a fitting curve of a quintic polynomial equation group. The method can effectively reduce the error between the set current output and the actual output, and ensure the consistency and accuracy of the current output.

[0004] The technical solution of the present invention is: a method for accurately controlling the current output size of a tinnitus diagnostic and therapeutic instrument, by setting current output parameters and using an external oscilloscope to observe the actual output current value, and sending the observed current value to a calibration program through a serial port; the calibration program uses a quintic polynomial to fit the current curve, and after multiple measurements and calculations, a more accurate fitting coefficient is obtained and stored in a chip flash, thereby achieving accurate control of the current output.

[0005] Further, the specific steps are as follows:

[0006] Step 1, setting a current output parameter x: setting a current output parameter x in the calibration program, the parameter controls the current output of the tinnitus diagnosis and treatment instrument;

[0007] Step 2: Observe the actual output current value y through an oscilloscope, and send the actual output current value y to the calibration program through the serial port;

[0008] Step 3: According to the following quintic polynomial equations:

[0009]

[0010] Substitute the set current output parameter x and the measured output current value y into the equation to obtain multiple equation groups; by collecting multiple groups of data, solve the unknown coefficients a, b, c, d, e, f in the equation group, and store the results in the flash, so as to establish a fitting relationship between the current output parameter and the actual current output;

[0011] Step 4: During the operation of the device, the application can directly read the coefficients a, b, c, d, e, and f stored in the flash; according to the set current output parameter x, the actual output current is calculated using the stored coefficients to achieve precise control of the current size.

[0012] Furthermore, the entire current output range is divided into several intervals by adopting segmented fitting; a fifth-order polynomial fitting is performed for each interval to obtain the fitting coefficient of each interval.

[0013] Furthermore, step three is repeated multiple times to obtain multiple groups of a, b, c, d, e, and f values, and their average value is taken as the final coefficient.

[0014] Furthermore, multiple calibrations are performed regularly; during each calibration process, the current output data is recollected and the coefficients a, b, c, d, e, and f of the fitting equation are updated to ensure the accuracy of the fitting relationship.

[0015] The beneficial effect of the present invention is that the present invention proposes a method of establishing a fifth-order polynomial equation and fitting a current output curve, which can effectively reduce the error between the current setting value and the actual output value, and improve the current output accuracy of the tinnitus diagnosis and treatment instrument. The method has strong applicability, can significantly improve the performance and consistency of the equipment, and provide a more stable current output guarantee for tinnitus diagnosis and treatment. DETAILED DESCRIPTION

[0016] The reference current calibration program of the present invention runs on a tinnitus diagnosis and treatment instrument product, which has an electrical stimulation function and realizes electrical stimulation by outputting a larger current. The specific steps of the method are as follows:

[0017] 1. Parameter setting:

[0018] A current output parameter x is set in the calibration procedure, and this parameter controls the current output of the tinnitus diagnosis and treatment instrument.

[0019] 2. Actual current observation:

[0020] While the current is being output, the external oscilloscope observes the actual output current value y and sends the measured current value y to the calibration program through serial communication.

[0021] 3. Quintic polynomial fitting:

[0022] According to the following quintic polynomial equations:

[0023]

[0024] Substitute the set current output parameter x and the measured output current value y into the equation to obtain multiple sets of equations. By collecting multiple sets of data, the unknown coefficients a, b, c, d, e, and f in the equations are solved to establish a fitting relationship between the current output parameter and the actual current output.

[0025] 4. Segment fitting:

[0026] To further improve the accuracy, the entire current output range is divided into several intervals. A fifth-order polynomial fitting is performed for each interval to obtain the fitting coefficient of each interval. Segmented fitting can more accurately describe the characteristics of different current intervals, reduce fitting errors, and avoid the oscillation problem of high-order polynomials at the interval boundaries.

[0027] 5. Solving the fitting coefficients:

[0028] After substituting multiple sets of data into the quintic polynomial equation, solve the values ​​of coefficients a, b, c, d, e, and f.

[0029] In order to improve the accuracy, the process is repeated multiple times to obtain multiple sets of a, b, c, d, e, and f values.

[0030] 6. Multiple calibration and coefficient update:

[0031] Considering the influence of temperature, environmental changes and other factors on current output, this method performs multiple calibrations regularly. During each calibration process, the current output data is recollected and the coefficients a, b, c, d, e, and f of the fitting equation are updated to ensure the accuracy of the fitting relationship. After obtaining multiple sets of fitting coefficients through multiple calibrations, the average value is taken as the final coefficient and stored in the chip's Flash so that the application can read it directly to ensure the long-term stability of the current output.

[0032] 7. Practical application:

[0033] During device operation, the application can directly read the coefficients a, b, c, d, e, and f stored in the flash.

[0034] According to the set current output parameter x, the actual output current is calculated using the stored coefficients to achieve precise control of the current size.

[0035] The present invention provides a method for accurately controlling the current output intensity of a tinnitus diagnostic and therapeutic instrument. The method sets the current output parameters, observes the actual output current value using an external oscilloscope, and sends the observed current value to a calibration program through a serial port. The calibration program uses a quintic polynomial to fit the current curve, and after multiple measurements and calculations, a more accurate fitting coefficient is obtained and stored in a chip flash, thereby achieving accurate control of the current output. The present invention improves the current output accuracy of the tinnitus diagnostic and therapeutic instrument and ensures the output consistency of different devices under the same settings.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
