[0025] The technical solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1 , Figure 1 A flow chart of a compound wave control method for pelvic floor muscle recovery provided in an embodiment of the present application. The compound wave control method for pelvic floor muscle recovery provided in an embodiment of the present application is implemented by a compound wave control device for pelvic floor muscle recovery. The compound wave control device for pelvic floor muscle recovery includes but is not limited to an electronic therapeutic device and various pelvic floor muscle rehabilitation instruments.

[0027] like Figure 1 As shown, the complex wave control method for pelvic floor muscle recovery includes steps S101 to S104. The details are as follows:

[0028] S101: Obtain reference time of each waveform component, and analyze the reference time using component time alignment rules.

[0029] The reference time of each waveform component is the preset start time. Since each waveform component may have a different initial phase, if unified synchronization is not performed, the time difference between the actual start time and the reference time is reflected as a phase difference. In addition, during the propagation of different waveform components, path length, medium characteristics or interference will cause propagation delays, resulting in time differences. In order to solve the time difference problem, it is necessary to

[0030] In order to solve the time difference problem, the embodiment of the present application uses the component time alignment rule to analyze the difference between the reference time and the actual start time and calculate the phase offset to achieve accurate synchronization of the components. In one embodiment, the reference time is analyzed using the component time alignment rule, including: based on the reference time of each waveform component, respectively calculating the time difference between the actual start time and the reference time of each waveform component; according to each time difference, respectively calculating the phase offset of each waveform component; based on the calculated phase offset, modulating the phase of each waveform component; according to each time difference, calculating the global reference time of each waveform component.

[0031] For any waveform component, assuming the reference time is t ref , represents the preset start time, which is used to synchronize multi-component waveforms; the actual start time is t act , represents the starting time point measured for the current waveform component. Then the calculated time difference is: Δt = t act -t ref , the time difference represents the delay or advance of the waveform component relative to the reference time. According to the time difference, the phase offset of the waveform component is calculated, which is expressed as: t=2πf·Δt;where f is the current frequency of the corresponding waveform component, w is the angular frequency, and the phase offset describes how the time difference of the waveform component is reflected in the phase. If the time difference is large, the phase offset may cause periodic changes.

[0032] The waveform components are analyzed for time alignment using phase offset as an indicator. Specifically, the phase of each waveform component is adjusted according to the calculated phase offset. This is a local adjustment, which processes each waveform component one by one, so that each waveform component can make instant corrections to the waveform component based on the reference time, solving the instant error problem relative to the reference time.

[0033] In one embodiment, the global reference time of each waveform component is calculated according to the time difference of each waveform component, which is expressed as: Among them, t ref-new is the global reference time of each waveform component, N is the number of waveform components, is the actual starting time of the i-th waveform component, is the reference time of the i-th waveform component. The global reference time adjusts the reference benchmark to minimize the difference between components from an overall perspective.

[0034] S102: Based on the analysis result of the reference time, respectively update the reference time of each waveform component.

[0035] Based on the analysis result of the reference time, the reference time of each waveform component is updated respectively, including: based on the global reference time, the reference time of each waveform component is updated.

[0036] It should be noted that phase difference correction usually occurs when the current reference time remains unchanged, and is used for local precise adjustment. If it is found that there is still a large error in the overall after local adjustment, the global reference time is used to optimize the global benchmark to reduce the difference between the waveform components. The combination of the two can achieve synchronization from local to global, making the multi-component composite wave have higher time and phase consistency.

[0037] S103: Acquire the reference frequency of each waveform component, analyze the reference frequency and adjust the frequency of each waveform component.

[0038] Obtaining the reference frequency of each waveform component, analyzing the reference frequency and adjusting the frequency of each waveform component, including: inputting each waveform component into a phase-locked loop, using the phase-locked loop to analyze the reference frequency and adjust the output frequency of each waveform component.

[0039] The phase-locked loop includes: an inner loop and an outer loop; the phase-locked loop is used to analyze the reference frequency and output the output frequency of each waveform component, including: for any waveform component, in the inner loop, the frequency error is calculated according to the reference frequency of the waveform component and the output frequency at the current moment; according to the frequency error and the inner loop gain, the output frequency of the waveform component is dynamically adjusted; in the outer loop, the average input frequency of the waveform component in the sliding window of the outer loop and the difference between the average input frequency and the output frequency at the current moment are calculated to obtain a frequency deviation signal; according to the frequency deviation signal and the outer loop gain, the frequency drift of the waveform component is corrected to obtain the output frequency of the waveform component.

[0040] According to the frequency error and the inner loop gain, the output frequency of the waveform component is dynamically adjusted, which is expressed as:

[0041] f t+1 =f t +k1×(f0-f t )

[0042] Among them, f t+1 is the output frequency at the next moment after the current moment t after dynamic adjustment, f t is the output frequency at the current moment, k1 is the inner loop gain, and f0 is the reference frequency.

[0043] By comparing the reference frequency of the waveform component and the output frequency at the current moment, the frequency error between the two is calculated, and then the output frequency is dynamically adjusted according to the frequency error and the inner loop gain. The inner loop gain is a proportional factor used to amplify or reduce the frequency error and control the sensitivity of the adjustment. The inner loop responds quickly and corrects the output frequency deviation in time to achieve real-time tracking of the reference frequency. The adjustment range is small and it is suitable for subtle correction of frequency errors.

[0044] According to the frequency deviation signal and the outer loop gain, the frequency drift of the waveform component is corrected to obtain the output frequency of the waveform component, which is expressed as:

[0045]

[0046] Among them, f s is the output frequency of the waveform component, k2 is the outer loop gain, is the frequency deviation signal, is the average input frequency in the outer loop sliding window, and N is the size of the outer loop sliding window.

[0047] Sliding window is a technique to take a fixed-length subset of a continuous or discrete time series. The outer loop sliding window is mainly used to analyze the short-term behavior of the input signal and help calculate and adjust the output frequency of the waveform component. In the outer loop, the sliding window contains the input frequency data of the waveform component.

[0048] It should be noted that the outer loop mainly deals with the long-term trend drift of the frequency, has a slower dynamic response and a larger adjustment range, and is used to compensate for the low-frequency error or accumulated deviation that the inner loop cannot correct. The inner loop is corrected in real time based on the outer loop to ensure frequency stability, and the outer loop corrects the benchmark of the inner loop through long-term observation to prevent drift accumulation.

[0049] S104: Generate and output a synchronous composite wave according to the adjusted phases and frequencies.

[0050] Through the above analysis, it can be known that the composite wave control method for pelvic floor muscle recovery provided by the embodiment of the present application includes: obtaining the reference time of each waveform component, analyzing the reference time using the component time alignment rule; updating the reference time of each waveform component based on the analysis result of the reference time; obtaining the reference frequency of each waveform component, analyzing the reference frequency and adjusting the frequency of each waveform component; generating and outputting a synchronous composite wave according to the updated reference time of each waveform component and the adjusted frequencies. By updating the reference time of each waveform component based on the time alignment rule and adjusting each frequency based on the reference frequency, it is intended to ensure that the multi-component combined waveform can be synchronized in time and frequency, and avoid the phenomenon of time offset or frequency mismatch in the multi-component combined waveform.
