As shown in FIG. 2, FIG. 2 is a schematic flowchart of the first embodiment of the dynamic magnetic field generation method of the present invention. In this embodiment, the dynamic magnetic field control method includes:

Step S10, receiving input preset signal parameters;

In order to realize the effect of dynamic magnetic field in the 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 the pulse current into the load coil (the 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 generating circuit of the pulse high current. As far as the generation circuit of high pulse current is concerned, the traditional dynamic magnetic field generator generally needs to manually test the frequency of the input signal many times to reach the resonance state, and further input the parameters of the generated signal, and additional data monitoring device is required, which leads to the dynamic In order to achieve an ideal treatment state of human orthopedic diseases, the magnetic field needs to spend a lot of time for debugging, the efficiency is relatively low, and it is difficult to maintain a stable dynamic magnetic field state.

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

Receive the input preset signal parameters. The preset signal parameters here can be input according to actual needs. The preset signal parameters can include signal frequency range, frequency sweep bandwidth and frequency sweep points, signal pulse width, signal duty cycle, and running time. , target peak current, etc. Preferably, the range of the above parameters can be:

Signal frequency range: 0.1Hz ~ 3GHz;

Sweep bandwidth range: 0.1Hz ~ 1GHz;

Sweep frequency range: 1 to 10000;

Signal pulse width range: 0～1s;

Signal duty cycle range: 0～100%;

Operating time range: 0～72h;

Target peak current range: 0～100A;

Step S20, according to a preset adaptive rule, adjust the preset signal parameters to obtain target signal parameters;

Specifically, step S20 includes:

Step a, outputting an initial signal according to the preset signal parameters, and acquiring a reflected signal corresponding to the initial signal;

The dynamic magnetic field generating device generates the initial radio frequency signal according to the input signal parameters. The initial signal here refers to the radio frequency signal generated when the dynamic magnetic field generating device first starts to work. The load coil end will reflect the initial signal, and the signal emitted by this part will be regarded as the reflected signal.

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

The dynamic magnetic field generating device has a signal monitoring device, which can monitor the voltage of each signal in the reflected signal through the signal monitoring device, 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.

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

dividing the frequency sweep bandwidth into segments with the same number of frequency sweep points;

Determine the specific segment corresponding to a specific signal;

determining signal monotonicity in the particular segment;

The frequency corresponding to the signal without signal monotonicity in the specific segment is taken as the target signal frequency.

Step c, inputting the target signal frequency into the preset signal parameters, and shielding the signal frequency range, frequency sweep bandwidth and frequency sweep points in the preset signal parameters to obtain the target signal parameters.

After the target signal frequency is determined, it is only necessary to output the radio frequency signal according to the target signal frequency, and temporarily shield the signal frequency range, frequency sweep bandwidth and frequency sweep points in the preset signal parameters. It has a signal frequency range, sweep bandwidth and sweep points. The reason for this is to generate a stable and therapeutically fixed frequency dynamic magnetic field, and if the dynamic magnetic field loses its stability due to other conditions, it will release the signal frequency range, Sweep bandwidth and sweep points, delete the target signal frequency from the preset signal parameters, start the next round of self-adaptation to determine a new target signal frequency, mask the corresponding signal frequency range, sweep bandwidth and sweep points, when This cycle occurs when the stability of the dynamic magnetic field is broken.

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

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

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

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. The relevant personnel can also flexibly input and configure the desired target according to the actual treatment needs. Signal pulse width, target signal duty cycle and target peak current to obtain the desired target signal. For the target peak current, it is necessary to determine the current current value first, and then gradually adjust the current current value to the target peak value according to the target peak current. current and determine whether the current current value is reached the target peak current. The process of gradually adjusting the current current value includes lowering or increasing the current current value.

By configuring multiple parameters such as 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 therapeutic effects can be achieved. Through the configuration of parameters, the device can flexibly generate the required dynamic magnetic field, and generate induced current in the treatment area of the bone band to achieve the purpose of treatment. It can also be combined with the static magnetic field to generate mechanical stimulation, electrical stimulation and A combination of one or more of mechanical vibration stimulation to modulate bone resorption and bone formation during bone metabolism.

Step S40, outputting the target signal, so as to obtain the time-dependent curve of the peak current and peak power of the target signal;

The target signal is obtained and output by adjusting the signal in the above steps, the spectrogram of the target signal and various parameter details of the target signal can be displayed in the dynamic magnetic field generating device, and the curve of the peak current and peak power of the target signal with respect to time can be obtained.

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

There can be multiple data export instructions. Different data export instructions correspond to different export methods. They can be exported in the form of data tables or in the form of maps. Preferably, they are exported in the form of discrete points, which is convenient for later data processing. Statistical Analysis.

The dynamic magnetic field generating method in the present invention receives input preset signal parameters, wherein the preset signal parameters include: the steps of signal frequency range, frequency sweep bandwidth and frequency sweep points, and adjusting all the parameters according to the preset adaptive rule. The step of presetting the signal parameters to obtain the target signal parameters can be adapted to the output frequency of the coil load end, so that the overall system where the dynamic magnetic field occurs is in a resonance 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 can be obtained by outputting the target signal The steps of changing the curve of peak current and peak power of the signal with respect to time and the step of outputting the changing curve when a preset data export instruction is received are convenient for later statistical analysis of data, so as to further upgrade and optimize the equipment. On the whole, compared with the dynamic magnetic field generating method applied by the traditional dynamic magnetic field generating device, the present invention is more efficient, stable and safer to generate a stable dynamic magnetic field, and ensures a dynamic magnetic field with a frequency required by orthopedic diseases, So as to have a good and effective treatment effect.

As shown in the figure, the process of the radio frequency signal used to generate the dynamic magnetic field at the coil load end from being generated to being converted into a dynamic magnetic field is as follows: The sequence number is as follows:

① Various parameters of the input signal are input through the monitoring software of the computer control terminal 1, and various signal parameters are transmitted to the signal synchronization device 2 and the signal excitation source 3;

2. The signal synchronization device 2 and the signal excitation source 3 coordinate to generate a modulated radio frequency signal, and transmit the radio frequency signal to the power amplifier 4; the signal synchronization device 2 generates a part of the carrier wave and transmits it to the signal monitoring device 6;

3. The power amplifier 4 proportionally amplifies the power of the radio frequency signal according to a preset ratio, and transmits the amplified radio frequency signal to the signal coupler 5;

④ The signal coupler 5 couples the amplified radio frequency signal and distributes the power of the radio frequency signal, and finally transmits the coupled radio frequency signal to the coil load terminal 7;

⑤ The coil load end 7 generates a dynamic magnetic field from the radio frequency signal according to the principle of electromagnetic induction; in actual conditions, 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.

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 state of resonance as a whole, that is, the coil load end 7 generates the frequency of the dynamic magnetic field (the coil The frequency of the radio frequency signal in the load terminal 7) is close to or the same as the frequency of the radio frequency signal.

The process of adaptive frequency of the dynamic magnetic field generating device 100 can be further described with reference to the above-mentioned process of generating a radio frequency signal generating a dynamic magnetic field at the load end of the coil to converting it into a dynamic magnetic field and the dynamic magnetic field control method:

When the dynamic magnetic field generating device 100 is just started, an unstable dynamic magnetic field will be generated according to various signal parameters input to the computer control terminal 1 by the relevant personnel. At this time, the frequency adaptive function in the monitoring software of the computer control terminal 1 will be activated.

Specifically, after the frequency adaptation starts, the reflected signal fed back by the coil load terminal 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 When the voltage value is zero or close to zero, it means that the dynamic magnetic field generating apparatus 100 is in a resonant state and retains the radio frequency signal of the current frequency and does not require frequency adaptation. When the difference between the voltage value and the zero voltage value is large, it is necessary to firstly scan the frequency sweep bandwidth input at the beginning, divide it into a preset number of segments, and quickly determine that the voltage value is zero or close to zero by the dichotomy method. In this segment, the method of confirming the monotonicity of the signal is used to determine the signal frequency that does not have monotonicity, retain the signal frequency, and transmit the signal frequency to the signal excitation source 3 through the computer control terminal 1, so that the The signal excitation source 3 only generates a radio frequency signal of the signal frequency, so that when the radio frequency signal is transmitted to the coil load end 7, a stable dynamic magnetic field can be generated, which cooperates with the external static magnetic field to carry out the treatment of human orthopedic diseases.

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

In addition, in the process of transmitting signals and generating a dynamic magnetic field inside the dynamic magnetic field generating device 100, the signals collected by the signal monitoring device 6 can be derived through the computer control terminal 1 for data export, and the derived forms are not limited to discrete points, tables, and spectrograms. , histogram, etc.

After the end, the collected information is exported in the form of discrete points, etc., which is convenient for later statistical analysis of data. The dynamic magnetic field generating device in the present invention can work adaptively and stably, adjust parameters flexibly, generate dynamic magnetic field in response to parameters quickly, and have good therapeutic effect and high efficiency on patients with orthopedic diseases.
