[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1: As Figure 1 As shown, the present invention provides a data consistency control method for a shortwave therapy device, comprising:

[0058] Step S1: Receive the set of target treatment parameters sent by the host computer, wherein the set of target treatment parameters includes at least the operating frequency and output power.

[0059] In this embodiment, the host computer and the main control system of the shortwave therapy device exchange data via a standard communication interface, including UART, SPI, CAN, or USB. The target treatment parameter set is transmitted from the host computer to the main control system's receive buffer in the form of structured data frames. Each data frame includes a frame start identifier, a parameter data area, and a frame check sequence. The parameter data area encapsulates the control parameters required for the treatment process, including at least the operating frequency and output power values. The operating frequency defines the energy carrier frequency of the shortwave therapy, while the output power characterizes the intensity of the therapeutic energy.

[0060] Step S2: Based on the pre-stored mapping table, dynamically map each parameter in the target treatment parameter set to the corresponding hardware configuration parameter set. The hardware configuration parameter set includes the oscillator control word and the power amplifier bias voltage control code.

[0061] In this embodiment, the mapping table is a non-linear mapping table, established based on the actual physical characteristics of the oscillator and power amplifier in the shortwave therapy device hardware circuit, characterizing the target treatment parameter, i.e., the operating frequency. Output power With the underlying hardware configuration parameters, i.e., the oscillator control word Power amplifier bias voltage control code The nonlinear correspondence between them.

[0062] The nonlinear mapping table was obtained through system calibration experiments. The specific process was as follows: within the entire permissible operating frequency range and output power range of the instrument, a series of discrete operating points were selected. For each discrete operating point, the optimal oscillator control word that enables the therapeutic instrument to achieve its predetermined output performance at that point is determined through instrument measurement and closed-loop feedback debugging. With power amplifier bias voltage control code This mapping relationship is then permanently stored, forming a lookup table containing multiple discrete entries. During system runtime, the parameter mapping module receives a table containing the target operating frequency. With target output power The parameter set. The dynamic mapping process first queries this nonlinear mapping table to determine the target parameter pair. Is it related to a discrete working point stored in the table? Exact match. If a match is found, the hardware configuration parameters corresponding to that discrete point are directly applied. As output, if the target parameter pair lies within the rectangular region formed by any four discrete operating points in the table, then the corresponding hardware configuration parameters are calculated using a bilinear interpolation algorithm. Specifically, in the two-dimensional parameter space composed of discrete points, the target point is located... A rectangular region, the four vertices of which are , , , Obtain the oscillator control word corresponding to these four vertices. , , , With power amplifier bias voltage control code , , , Bilinear interpolation calculations were performed on the oscillator control word and the bias voltage control code, respectively. For the oscillator control word, its target value... It is given by the following formula:

[0063]

[0064] Among them, interpolation coefficients , For the power amplifier bias voltage control code, its target value is... Using the same formula and interpolation coefficients , Perform the calculation.

[0065] Step S3: Based on the circuit physical characteristics of the shortwave therapy device, establish logical verification rules between hardware configuration parameters. After generating the hardware configuration parameter set, call the logical verification rules to verify the logical relationship between the oscillator control word and the power amplifier bias voltage control code. When the verification passes, determine that the data logic is consistent.

[0066] In this embodiment, the logic verification rules are established based on the impedance matching principle of the shortwave therapy device's transmission channel and the physical constraint relationship between the oscillator frequency and the power amplifier.

[0067] First, a theoretical model is constructed. The model establishment process is as follows: Based on the circuit structure of the shortwave therapy device's transmission channel, this structure includes an oscillator that generates high-frequency signals, an impedance matching network for transmission and matching, a power amplifier for power amplification, and a treatment load as the terminal. Its high-frequency equivalent circuit model is then established, including the output impedance of the oscillation source. Impedance matching networks Parameter matrix, input and output impedance characteristics of power amplifier transistors and its nonlinear transconductance properties and the equivalent impedance of the load. .

[0068] Based on the equivalent circuit model, the analysis is performed at different operating frequencies. Below, due to the frequency response characteristics of the impedance matching network, the therapeutic load impedance... The equivalent load impedance presented at the output of the power amplifier after reflection by the impedance matching network. The equivalent load impedance is the frequency. The function, whose calculation formula involves the network Parameters and load impedance calculations are performed. Then, based on the operating characteristics of the power amplifier, its output power is determined. ,efficiency With bias voltage Equivalent load impedance and input drive power A mathematical model of the relationship between them.

[0069] Mathematical relational models are expressed as a system of equations and ,in This is the fundamental component of the collector current of the power amplifier transistor. To be related to the bias voltage and input voltage amplitude Related transconductance, This represents the real part of the equivalent load impedance.

[0070] For a given target output power and operating frequency Under the premise of ensuring that the power amplifier operates in the safe area and meets the requirements of linearity and efficiency, its bias voltage Allowed range of valid values The lower limit of this range Ensure the power amplifier can be turned on and provide at least [amount missing]. The output power, upper limit Then, the maximum allowable collector-emitter voltage of the power amplifier transistor is used. Maximum power dissipation The boundaries of the safe working area, which are set up to prevent thermal breakdown, are jointly determined.

[0071] Using a theoretical model, all discrete operating points in the system calibration experiment were analyzed. Calculate and record the corresponding effective bias voltage range. Ultimately, the operating frequency will be... Target output power The calculated effective voltage range is associated with a logical verification rule table, which is then stored in the system's non-volatile memory.

[0072] After generating the hardware configuration parameter set, logical relationship verification is performed by invoking logical verification rules. The verification process specifically includes: parsing the hardware configuration parameter set to be verified and extracting the power amplifier bias voltage control code. The logic verification module receives the original set of target treatment parameters from the parameter receiving module. .

[0073] by The system uses an index to query a pre-stored logical verification rule table. Since the target point may not completely coincide with the discrete points in the rule table, the system employs a bilinear interpolation algorithm consistent with the parameter mapping module, based on the nearest discrete frequency power points in the rule table. , , , Stored effective voltage range boundary values Equal to Then, interpolation calculations are performed on the lower and upper limits of the effective voltage range to obtain the current target operating point. The effective range of the power amplifier bias voltage allowed below The interpolation formula is consistent with the formula in the parameter mapping. Next, the power amplifier bias voltage control code is... The conversion relationship of the digital-to-analog converter is used to analyze the corresponding actual voltage setpoint. Determine whether the voltage value satisfies the inequality: If the inequality is true, the check passes, the hardware configuration parameters are logically consistent, and the process continues. If the inequality is false, i.e. or If not, the verification will fail.

[0074] When the logical relationship verification fails, the system executes preset error handling procedures. The system then processes the set of oscillator control words. With power amplifier bias voltage control code The system marks the abnormal parameter pair and sets a dedicated verification failure flag in the system status register. Simultaneously, the system actively blocks the transmission of this abnormal parameter pair to the subsequent waveform generation and power drive circuits, ensuring that unreasonable configuration parameters are not loaded and executed, thus protecting the hardware circuitry. While implementing the blocking, the system returns a structured feedback signal to the host computer via the communication interface. This feedback signal includes the abnormal event identifier, specific out-of-limit direction information, and the original parameter pair that triggered the abnormality. and its parsed and the calculated effective voltage range , along with a timestamp.

[0075] Step S4: After the logic verification is passed, the hardware configuration parameter set is sent to the waveform generation circuit and the power drive circuit; the oscillation frequency status register value of the waveform generation circuit and the output voltage sample value of the power drive circuit are read in real time; the read oscillation frequency status register value and output voltage sample value are compared with the corresponding parameters to be executed in the hardware configuration parameter set.

[0076] In this embodiment, after the logic verification passes, the hardware configuration parameter set is synchronously sent to the waveform generation circuit and the power drive circuit via a parallel digital interface. Specifically, the oscillator control word is written into the frequency control register of the digitally controlled oscillator in the waveform generation circuit to set the target operating frequency. The power amplifier bias voltage control code is written into the input register of the digital-to-analog converter in the power drive circuit to set the target bias voltage. .

[0077] After the parameters are sent, the system initiates the real-time monitoring and consistency comparison process. First, an instantaneous value comparison is performed. The system obtains the instantaneous measurement value of the actual frequency output by the oscillation circuit by reading the oscillation frequency status register corresponding to the frequency monitoring module integrated within the waveform generation circuit. The frequency status register is driven by a dedicated phase-locked loop and counter circuit, and its value is determined by a pre-stored scaling factor. The frequency value is obtained after conversion, that is ,in The system reads values ​​from the registers. Simultaneously, it uses an analog-to-digital converter to sample the voltage divider points in the power amplifier power supply circuit of the power drive circuit in real time, obtaining the instantaneous sampled value of the actual operating voltage of the power amplifier. The sampled value is converted using pre-stored conversion coefficients. Converted to voltage value, i.e. ,in This is the output code value of the analog-to-digital converter.

[0078] The system will read the actual value , The actual oscillation frequency is calculated by comparing it with the target parameters in the set of hardware configuration parameters to be executed. With the target frequency setting value The first relative deviation between The calculation formula is: Calculate the actual sampled voltage. With the target voltage set value The second relative deviation between The calculation formula is: The system has a preset first deviation threshold. With the second deviation threshold Only if both conditions are met. With conditions At that time, the instantaneous value consistency comparison is deemed successful.

[0079] To improve anti-interference capability and robustness of judgment, statistical value comparison based on a sliding time window is performed synchronously. A sliding time window of fixed length is set. Within this time window, at a fixed sampling period... The oscillation frequency status register value and the output voltage sample value are sampled multiple times consecutively to form a data structure containing... Instantaneous frequency value sequence of sampling points With instantaneous voltage value sequence ,in .

[0080] Subsequently, the statistical characteristic values ​​of the two instantaneous value sequences are calculated separately. For the frequency sequence... Calculate its statistical average. with sample standard deviation Statistical mean The calculation formula is Sample standard deviation The calculation formula is For voltage sequences The statistical average is calculated using the same formula. with sample standard deviation .

[0081] The system compares the calculated statistical feature values ​​with the target parameter values. First, it calculates the frequency statistical average. With target frequency Compare and calculate the average frequency deviation. , Statistical average of voltage With target voltage Compare and calculate the average voltage deviation. , The system has a preset average frequency deviation threshold. Average voltage deviation threshold Frequency standard deviation threshold and voltage standard deviation threshold The criteria for passing the statistical consistency comparison based on the sliding time window are that the following four inequalities must be satisfied simultaneously: ,and ,and ,and The system determines that a consistency comparison passes if both the instantaneous value comparison and the statistical value comparison based on the sliding time window are met simultaneously.

[0082] Step S5: Trigger parameter loading and output control signals only when the consistency comparison passes.

[0083] In this embodiment, the global consistency flag position within the system is valid only when both the instantaneous value comparison condition and the statistical value comparison condition are met.

[0084] At this time, the main control system generates a high-level load enable pulse signal, which is synchronously sent to the parameter latch registers of the waveform generation circuit and the power drive circuit via the control bus. The rising edge of the load enable pulse latches the oscillator control word and the power amplifier bias voltage control code currently temporarily stored in the input registers of the above circuits into their respective execution registers, completing the loading and activation of the hardware configuration parameters.

[0085] After parameter loading is complete, the system generates a treatment enable signal, which is sent to the RF power switch and modulation circuit to control the output of treatment energy to the load terminal according to the set operating frequency and output power. If either the instantaneous value comparison or statistical value comparison condition is not met, the global consistency flag remains invalid, and the system does not generate a loading enable pulse or treatment enable signal. Simultaneously, the system blocks the current treatment process, records the currently monitored actual frequency value sequence, actual voltage value sequence, calculated deviation values, and target parameter values ​​to the error log in non-volatile memory, and sends a status report containing detailed inconsistency information to the host computer via the communication interface.

[0086] Example 2: The present invention provides a data consistency control method for a shortwave therapy device, which also includes a dynamic calibration and optimization mechanism based on runtime parameter feedback.

[0087] After the consistency comparison passes and the treatment output is triggered, the system enters a continuous runtime monitoring state. At this time, the system not only continuously acquires the oscillation frequency status register value and the output voltage sampling value, but also simultaneously acquires the final output power and waveform purity parameters fed back from the treatment output terminal via the coupler. The system performs correlation analysis with the above runtime monitoring parameters, the target treatment parameter set, and the loaded hardware configuration parameter set to construct a runtime parameter relationship database.

[0088] Based on this database, the system periodically performs parameter optimization. The optimization process includes: analyzing the hardware configuration parameters corresponding to the optimal output performance actually achieved under a specific operating frequency and output power target, and fine-tuning and updating the pre-stored nonlinear mapping relationship table and logic verification rules accordingly.

[0094] Output control module: Triggers parameter loading and output control signals only when the consistency comparison passes.
