[0035] Optionally, the terminal may further include a microphone, a speaker, an RF (Radio Frequency) circuit, a sensor, an audio circuit, a wireless module, etc. Among them, sensors such as image sensors, distance sensors, acceleration sensors and other sensors are not described in detail here.

[0036] Those skilled in the art will understand that Figure 1 The terminal structure shown in the figure does not constitute a limitation on the terminal, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0037] like Figure 2 As shown, Figure 2 : is a flow chart of a first embodiment of a method for generating a dynamic magnetic field according to the present invention. In this embodiment, the method for controlling a dynamic magnetic field includes:

[0038] Step S10, receiving input preset signal parameters;

[0039] In order to achieve the effect of dynamic magnetic field treatment of orthopedic diseases, a dynamic magnetic field generator with stable operation, flexible and adjustable parameter range and large magnetic field parameters is required. The working principle of the dynamic magnetic field generator is mainly to pass pulse current into the load coil (coil load end) to generate the required dynamic magnetic field around the load coil. The dynamic magnetic field generator mainly includes two parts, one is the load coil, and the other is the pulse large current generation circuit. As for the pulse large current generation circuit, the traditional dynamic magnetic field generating device generally requires manual multiple tests of the frequency of the input signal to achieve the resonant state, further input the signal parameters, and set up a data monitoring device. This leads to the dynamic magnetic field to achieve a relatively ideal state for the treatment of human orthopedic diseases. It takes a lot of time to debug, the efficiency is relatively low, and it is difficult to maintain a stable dynamic magnetic field state.

[0040] In this embodiment, the dynamic magnetic field control method can be applied to a dynamic magnetic field generating device.

[0041] Receive input preset signal parameters, where the preset signal parameters can be input according to actual needs, and the preset signal parameters may include signal frequency range, sweep bandwidth and number of sweep points, signal pulse width, signal duty cycle, operating time, target peak current, etc. Preferably, the range of the above parameters can be:

[0042] Signal frequency range: 0.1Hz~3GHz;

[0043] Sweep bandwidth range: 0.1Hz~1GHz;

[0044] Sweep frequency point range: 1 to 10000;

[0045] Signal pulse width range: 0~1s;

[0046] Signal duty cycle range: 0~100%;

[0047] Operating time range: 0~72h;

[0048] Target peak current range: 0~100A;

[0049] Step S20, adjusting the preset signal parameters according to preset adaptive rules to obtain target signal parameters;

[0050] Specifically, step S20 includes:

[0051] Step a, outputting an initial signal according to the preset signal parameters, and obtaining a reflected signal corresponding to the initial signal;

[0052] The dynamic magnetic field generating device generates an initial radio frequency signal based on the input signal parameters. The initial signal here refers to the radio frequency signal generated when the dynamic magnetic field generating device starts to work. After the initial signal is sent, the load coil end in the dynamic magnetic field generating device will reflect the initial signal, and this part of the transmitted signal will be used as the reflected signal.

[0053] Step b, determining a specific signal with the smallest voltage value in the reflected signal, and determining a target signal frequency corresponding to the specific signal;

[0054] The dynamic magnetic field generating device will have a signal monitoring device, which can monitor the voltage of each signal in the reflected signal, and then determine the specific signal with the smallest voltage value in the reflected signal through comparison, and determine the target signal frequency of the specific signal.

[0055] Specifically, the step of determining the target signal frequency of the characteristic signal may include:

[0056] Dividing the frequency sweep bandwidth into segments having the same number as the number of frequency sweep points;

[0057] Determine a specific segment corresponding to a specific signal;

[0058] determining signal monotonicity in the particular segment;

[0059] The frequency corresponding to the signal without signal monotonicity in the specific segment is used as the target signal frequency.

[0060] Step c: inputting the target signal frequency into the preset signal parameters, and masking the signal frequency range, frequency sweep bandwidth and frequency sweep point number in the preset signal parameters to obtain the target signal parameters.

[0061] After determining the target signal frequency, it is only necessary to output the RF signal according to the target signal frequency, and temporarily shield the signal frequency range, sweep bandwidth and number of sweep points in the preset signal parameters. This is equivalent to not having the signal frequency range, sweep bandwidth and number of sweep points in the preset signal parameters. The reason for doing this is to produce a stable and therapeutic fixed-frequency dynamic magnetic field. If the dynamic magnetic field loses stability due to other conditions, the signal frequency range, sweep bandwidth and number of sweep points are released, and the target signal frequency is deleted from the preset signal parameters. The next round of adaptive determination of the new target signal frequency begins, and the corresponding signal frequency range, sweep bandwidth and number of sweep points are shielded. This cycle is repeated when the stability of the dynamic magnetic field is broken.

[0062] Step S30, obtaining a signal to be corrected according to the target signal parameter, and adjusting the signal to be corrected to determine the target signal;

[0063] Specifically, the step of adjusting the signal to be corrected to determine the target signal includes:

[0064] Step d, receiving input target signal pulse width, target signal duty cycle and target peak current, and adjusting the signal to be corrected according to the target signal pulse width, the target signal duty cycle and the target peak current to determine the target signal.

[0065] After the frequency of the output RF signal is determined, the signal pulse width, signal duty cycle and peak current of the output RF signal are still the original values. Relevant personnel can also flexibly input and configure the desired target signal pulse width, target signal duty cycle and target peak current according to actual treatment needs to obtain the desired target signal. For the target peak current, it is necessary to first determine the current value, and then gradually adjust the current value to the target peak current according to the target peak current and determine whether the current value reaches the target peak current. The process of gradually adjusting the current current value includes lowering or raising the current current value.

[0066] By configuring multiple parameters such as the target signal pulse width, target signal duty cycle, and target peak current, one or more operating states in the process of dynamic magnetic field generation can be dynamically and flexibly increased or decreased, and different treatment effects can be achieved. Through parameter configuration, the device can flexibly generate the required dynamic magnetic field and generate induced current in the bone band treatment area to achieve the purpose of treatment. It can also be combined with the static magnetic field to generate one or more combinations of mechanical stimulation, electrical stimulation, and mechanical vibration stimulation in the bone band treatment area, thereby regulating bone absorption and bone formation in the process of bone metabolism.

[0067] Step S40, outputting the target signal to obtain a curve of changes in peak current and peak power of the target signal with respect to time;

[0068] By adjusting the signal through the above steps to obtain and output the target signal, the spectrum diagram of the target signal and various parameter details can be displayed in the dynamic magnetic field generating device, and the change curve of the peak current and peak power of the target signal with respect to time can be obtained.

[0069] Step S50: when a preset data export instruction is received, the change curve is output.

[0070] There may be multiple data export instructions, and different data export instructions correspond to different export methods. The data may be exported in the form of a data table or in the form of a graph. Preferably, the data may be exported in the form of discrete points to facilitate later data statistical analysis.

[0071] The dynamic magnetic field generating method in the present invention receives input preset signal parameters, wherein the preset signal parameters include: a signal frequency range, a sweep bandwidth and a sweep point number, and a step of adjusting the preset signal parameters to obtain the target signal parameters according to a preset adaptive rule, which can adapt the output frequency of the coil load end, so that the overall system of the dynamic magnetic field generation is in a resonant state, thereby reducing the loss of signal power and ensuring the generation of a stable dynamic magnetic field. By obtaining the signal to be corrected according to the target signal parameters and adjusting the signal to be corrected to determine the target signal, a stable electrical signal required for the treatment of orthopedic diseases can be generated, and the target signal is output to obtain the peak current and peak power of the target signal with respect to the time change curve, and when the preset data export instruction is received, the change curve is output, which is convenient for later data statistical analysis, thereby further upgrading and optimizing the equipment. Overall, compared with the dynamic magnetic field generating method used by the traditional dynamic magnetic field generating device, the present invention generates a stable dynamic magnetic field more efficiently, more stable and safer, ensuring that the dynamic magnetic field of the frequency required for orthopedic diseases is achieved, thereby having a good and effective therapeutic effect.

[0072] In addition, if Figure 3 As shown, Figure 3 FIG. 1 is a schematic diagram of a magnetic field generating device structure of an embodiment of a dynamic magnetic field generating device of the present invention. The present invention further provides a dynamic magnetic field generating device 100, and the dynamic magnetic field generating device 100 includes:

[0073] Computer control terminal 1, signal synchronization device 2, signal excitation source 3, power amplifier 4, signal coupler 5, signal monitoring device 6 and coil load terminal 7.

[0074] The computer control terminal 1 is used to receive various signal parameters input by relevant personnel, including signal frequency, bandwidth, duty cycle, sampling parameters, expected current and other parameters, and transmit various signal parameters to the signal synchronization device 2 and the signal excitation source 3. The computer control terminal 1 can be installed with monitoring software that matches the dynamic magnetic field generating device 100, and the computer control terminal equipped with the monitoring software is used as the control module of the dynamic magnetic field generating device 100.

[0075] The signal synchronization device 2 is used to transmit the generated high-frequency carrier to the signal excitation source 3 and the signal monitoring device 6 respectively. The high-frequency carrier has high energy and can penetrate human bones. Specifically, the waveform of the carrier generated by the signal synchronization device 2 can be a rectangular wave, a sawtooth wave, a triangle wave, a peak wave, a step wave, etc. The frequency is 0.1Hz-3GHz and can be adjusted by the computer control terminal 1.

[0076] The signal excitation source 3 is used to generate the original signal, and modulate the carrier generated by the signal synchronization device 2, and transmit the modulated RF signal to the power amplifier 4. The original signal waveform generated by the signal excitation source 3 can be any waveform, the frequency is adjustable from 0.1Hz to 3GHz, the duty cycle is adjustable from 0 to 100%, and the peak current is adjustable from 0 to 100A. The frequency and peak current (amplitude) can be adjusted in combination to generate a waveform signal with regular or irregular frequency and peak value. The range of the above parameters can be adjusted through the computer control terminal 1.

[0077] The power amplifier 4 amplifies the signal power according to a preset ratio and transmits it to the signal coupler 5 ; the signal coupler 5 transmits the signal to the coil load end 7 , and at the same time collects a part of the signal and transmits it to the signal monitoring device 6 .

[0078] The signal monitoring device 6 feeds back the monitoring result to the computer control terminal 1. The signal monitoring device 6 can be used as a data acquisition monitoring module of the dynamic magnetic field generating device 100.

[0079] The computer control terminal 1, the signal synchronization device 2, the signal excitation source 3, the power amplifier 4, the signal coupler 5, the signal monitoring device 6 and the coil load terminal 7 are electrically connected through a coaxial cable.

[0080] The dynamic magnetic field generating device in this embodiment has the advantages of high power, fast dynamic response and high accuracy. The dynamic magnetic field generating device is used to generate a dynamic magnetic field and is combined with an external static magnetic field for orthopedic treatment. It can generate controllable physical effects such as vibration, sound waves, and current in the area to be treated inside the bone to promote bone reconstruction and bone repair.

[0081] Specifically, in one embodiment, the connection relationship between the various devices constituting the dynamic magnetic field generating device 100 is:

[0082] The input terminal 11 of the signal synchronization device 2 is connected to the first output terminal 9 of the computer control terminal 1, the first output terminal 13 of the signal synchronization device 2 is connected to the first input terminal 15 of the signal excitation source 3, and the second output terminal 12 of the signal synchronization device 2 is connected to the first input terminal 24 of the signal monitoring device 6.

[0083] The second input terminal 14 of the signal excitation source 3 is connected to the second output terminal 10 of the computer control terminal 1 , the output terminal 16 of the signal excitation source 3 is connected to the input terminal 17 of the power amplifier 4 ; the output terminal 18 of the power amplifier 4 is connected to the input terminal 19 of the signal coupler 5 .

[0084] The coupling end 21 of the signal coupler 5 is connected to the second input end 22 of the signal monitoring device 6 , the output end 20 of the signal coupler 5 is connected to the coil load end 7 ; the output end 23 of the signal monitoring device 6 is connected to the input end 8 of the computer control end 1 .

[0085] Among them, you can refer to Figure 4 , Figure 4 The figure is a schematic diagram of the radio frequency signal transmission process involved in the dynamic magnetic field generating device of the present invention. As shown in the figure, the process of the radio frequency signal used to generate a dynamic magnetic field at the coil load end from generation to conversion into a dynamic magnetic field is as follows in sequence:

[0086] ① Input various signal parameters through the monitoring software of the computer control terminal 1, and transmit the various signal parameters to the signal synchronization device 2 and the signal excitation source 3;

[0087] ② The signal synchronization device 2 and the signal excitation source 3 coordinate and generate a modulated RF signal, and transmit the RF signal to the power amplifier 4; the signal synchronization device 2 generates a partial carrier and transmits it to the signal monitoring device 6;

[0088] ③ The power amplifier 4 amplifies the power of the RF signal in a proportional manner according to a preset ratio, and transmits the amplified RF signal to the signal coupler 5;

[0089] ④ The signal coupler 5 couples the amplified RF signal to distribute the RF signal power, and finally transmits the coupled RF signal to the coil load end 7;

[0090] ⑤ The coil load end 7 generates a dynamic magnetic field with the radio frequency signal according to the principle of electromagnetic induction; in actual situations, the coil load end 7 will reflect a part of the radio frequency signal, and this part of the reflected signal is transmitted to the signal monitoring device 6 through the signal coupler.

[0091] It should be noted that in order to generate a stable dynamic magnetic field, the dynamic magnetic field generating device 100 needs to automatically adapt to the coil load end 7 so that the dynamic magnetic field generating device 100 is in a resonant state as a whole, that is, the frequency of the dynamic magnetic field generated by the coil load end 7 (the frequency of the RF signal in the coil load end 7) is close to or the same as the frequency of the RF signal.

[0092] The process of the dynamic magnetic field generating device 100 adapting the frequency can be further described by referring to the process of the RF signal generating the dynamic magnetic field at the coil load end from generation to conversion into the dynamic magnetic field and the dynamic magnetic field control method:

[0093] When the dynamic magnetic field generating device 100 is just started, it will generate an unstable dynamic magnetic field according to various signal parameters input into the computer control terminal 1 by relevant personnel, and at this time, the frequency adaptation function in the monitoring software of the computer control terminal 1 will be started.

[0094] Specifically, after the frequency adaptation begins, the reflected signal fed back from the coil load end will be monitored in real time through the signal monitoring device 6. Specifically, the voltage value of the reflected signal can be monitored and transmitted to the computer control terminal 1. When the voltage value is zero or close to zero, it means that the dynamic magnetic field generating device 100 is in a resonant state and the RF signal of the current frequency is retained without frequency adaptation. When the voltage value is far from the zero voltage value, it is necessary to first scan the sweep bandwidth input at the beginning in segments, divide it into a preset number of segments, and quickly determine the segment corresponding to the voltage value of zero or close to zero by binary division. Then, in the segment, by confirming the monotonicity of the signal, determine the signal frequency that is not monotonic, retain the signal frequency, and transmit the signal frequency to the signal excitation source 3 through the computer control terminal 1, so that the signal excitation source 3 only generates the RF signal of the signal frequency, so that when the RF signal is transmitted to the coil load end 7, a stable dynamic magnetic field can be generated, and cooperate with the external static magnetic field to start the treatment of human orthopedic diseases.

[0095] During the frequency adaptation process, the real-time frequency will be displayed on the computer control terminal, and after the frequency adaptation is completed, the final fixed frequency will be displayed.

[0096] In addition, during the process of transmitting signals and generating dynamic magnetic fields inside the dynamic magnetic field generating device 100, the signals monitored and collected by the signal monitoring device 6 can be exported through the computer control terminal 1, and the export form is not limited to discrete points, tables, spectrum diagrams, bar graphs, etc.

[0097] In this embodiment, only relevant signal parameters need to be input in the software interface of the computer to control the dynamic magnetic field generating device to perform frequency adaptation and generate the expected current signal. At the same time, the current signal is collected and monitored in real time, and after the information collection is completed, the collected information can be exported in the form of discrete points, etc., which is convenient for later data statistical analysis. The dynamic magnetic field generating device in the present invention can work stably and adaptively, and flexibly adjust parameters, quickly respond to parameters to generate dynamic magnetic fields, and has good treatment effects and high efficiency for patients with orthopedic diseases.

[0098] In order to facilitate the understanding and application of the dynamic magnetic field generating method and the dynamic magnetic field generating device of the present invention, a brief but complete working process embodiment of the dynamic magnetic field generating device is provided here:

During the frequency adaptive process, the frequency scanning display window of the monitoring software displays the frequency scanning results in real time.

[0103] ⑤ After the frequency adaptation is completed, the coupling end 21 of the signal coupler of the dynamic magnetic field generating device 100 is connected to the signal monitoring device 6, and the isolation end is left empty;

[0105] ⑦ Observe the current value in the real-time peak current window of the control module interface of the monitoring software, click the current increase or current decrease button to adjust the current to reach the target peak current, and finally click the current confirmation button;

[0107] ⑨Right-click the mouse in the data acquisition and monitoring module interface of the monitoring software, and then click the export button to select different data export methods to export data;

[0108] ⑩ The exported data exists in the form of discrete points, including data such as acquisition points, real-time peak current and real-time peak power, and the obtained data can be statistically analyzed according to needs; after the data acquisition and export are completed, click the Cancel Acquisition button, and then click the Stop Test button to exit the monitoring software program. Finally, turn off the related equipment of the dynamic magnetic field generating device 100 or directly turn off the dynamic magnetic field generating device 100 as a whole through the computer control terminal 1.

[0109] The dynamic magnetic field generating device for orthopedic treatment of the present invention only needs to input relevant parameters in the computer software control interface to control the dynamic magnetic field generating device to perform frequency adaptation and generate expected output current signals, and at the same time, the output current signals are collected and monitored in real time, and after the information collection is completed, the collected information can be exported in the form of discrete points, which is convenient for later data statistical analysis. Through the control of the software of the present invention, the dynamic magnetic field generating device can work stably, flexibly adjust parameters, and respond quickly.
