[0020] Figure 1 It is a flowchart of the present invention;
[0021] Figure 2 It is a schematic diagram of the method steps of the present invention. DETAILED DESCRIPTION
[0022] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.
[0023] Embodiment 1;
[0024] Please refer to Figure 1 This embodiment provides a dynamic power supply control system for a laser gyro, including a power supply module, a power collection module and a main control module, wherein the power supply module is used to supply power to the laser of the laser gyro, the power collection module is used to record and collect the output power of the laser of the laser gyro, and the main control module performs calculation processing based on the actual output power of the laser of the laser gyro recorded and collected by the power collection module to obtain an adjustment instruction, and adjusts the power supply parameters of the power supply module;
[0025] The power supply module includes an input power supply, a starting circuit and a current stabilizing circuit. The input power supply is used to supply power to the laser of the laser gyroscope. The starting circuit includes a current limiting resistor, a starting capacitor, a thyristor and a trigger circuit. The current limiting resistor is located between the input power supply and the anode of the thyristor. The starting capacitor is connected in parallel with the current limiting resistor and is connected to the anode of the thyristor. The cathode of the thyristor is connected to the current stabilizing circuit. The trigger circuit is connected to the gate loop of the thyristor and includes a trigger resistor and a discharge resistor connected in series. The trigger resistor is closer to the gate of the thyristor than the discharge resistor. The current stabilizing circuit includes an adjustment tube and a filter capacitor. The input end of the adjustment tube is connected to the cathode of the thyristor, and the output end thereof is connected to the laser of the laser gyroscope through the filter capacitor. In this embodiment, it should be added that the main purpose of the starter circuit is to provide the laser gyro laser with the high-voltage pulse required for starting, so as to ignite the laser lamp tube. Specifically, the process includes two stages: the initial discharge stage and the instantaneous ionization stage. In the initial discharge stage, when the circuit is connected, the power supply voltage is applied to the two electrodes of the starter through the ballast and the lamp filament, so that the inert gas in the starter is ionized and a glow discharge is generated. This discharge process causes the bimetallic strip of the starter to expand due to heat, the contact point is closed, and the current forms a path through the ballast and the filament. In the instantaneous ionization stage, due to the sudden interruption of the circuit, the ballast generates a self-induced electromotive force and a high-voltage pulse, which ionizes the gas and steam in the lamp tube, and the current passes between the two opposite emission electrodes, thereby igniting the laser lamp tube.
[0026] The current stabilization circuit is responsible for providing a stable current after the laser is started to ensure the stability of the working state of the laser. The current stabilization circuit usually adopts a double-layer winding and maintains the stability of the output current through a feedback mechanism. The working principle of the current stabilizer is based on feedback control and current stabilization regulation. By measuring the output current and comparing it with the set value, the working state of the control circuit is continuously adjusted to maintain the stability of the output current. The core of the current stabilizer is the current stabilization control circuit, which adjusts the output current according to the feedback signal. When the output current exceeds the set value, the feedback circuit will detect this change and send a corresponding signal to the current stabilization control circuit. The current stabilization control circuit adjusts its working state according to the received signal, such as changing the state of the resistor or switch to make the output current return to the set value. In this embodiment, the synergistic effect of the ignition circuit and the current stabilization circuit enables the laser gyro dynamic power supply control system to achieve rapid startup and stable operation. The ignition circuit ensures that the laser can be ignited quickly, and the current stabilization circuit ensures that the laser works under stable current conditions after ignition, thereby improving the performance and reliability of the laser gyro. It not only improves the response speed and control accuracy of the system, but also helps to extend the service life of the laser, ensuring that the laser gyro can maintain high-precision output under various working conditions;
[0027] In addition, the main control module includes a feedback control unit and a feedforward control unit, and the calculation process of the adjustment instruction includes: the feedback control unit calculates and generates a preliminary adjustment instruction according to the difference between the actual output power and the set power collected by the record, the power supply module performs preliminary adjustment of the power supply parameters after receiving the preliminary adjustment instruction output by the feedback control unit, and the feedforward control unit generates an adjustment instruction correction amount based on the status parameters of the laser gyroscope after the power supply module performs preliminary adjustment of the power supply parameters, so as to correct and adjust the primary adjustment instruction, and output the adjustment instruction.
[0028] It should be noted that this system realizes precise control of the laser gyro laser by combining the power supply module, the power collection module and the main control module. The power supply module includes an input power supply, a ignition circuit and a current stabilization circuit. The ignition circuit is responsible for starting the laser, and the current stabilization circuit ensures the stability of the current. The power collection module collects the output power data of the laser and transmits it to the main control module. The feedback control unit in the main control module calculates the preliminary adjustment instruction according to the difference between the actual output power and the set power, and the feedforward control unit generates the adjustment instruction correction amount according to the laser gyro status parameters after the power supply parameters are adjusted, so as to correct the preliminary adjustment instruction and output the final adjustment instruction;
[0029] In the specific implementation process, the power supply module is first started to supply power to the laser gyro, and at the same time, the power acquisition module starts to record and collect the output power of the laser gyro. The main control module receives the actual output power data of the laser gyro collected by the power acquisition module, and compares it with the set power, calculates the power difference, and the feedback control unit calculates the preliminary adjustment instruction according to the power difference and the proportional control gain. The power supply module adjusts the power supply parameters according to the preliminary adjustment instruction. The feedforward control unit collects the laser gyro state parameters after the power supply parameters are adjusted, including the laser beam quality and laser temperature, calculates the adjustment instruction correction amount through the trained automatic encoder model algorithm, and calculates and generates the final adjustment instruction by combining the adjustment instruction correction amount and the preliminary adjustment instruction. The main control module sends the final adjustment instruction to the power supply module, and the power supply module accurately adjusts the power supply parameters according to the final adjustment instruction. It not only improves the working efficiency and stability of the laser gyro, but also extends the service life of the laser, and also improves the reliability and efficiency of the entire power supply system. In addition, the system adopts digital control, which makes the design and debugging of the system easier, reduces the dependence on analog circuits, and thus reduces the complexity and cost of the system.
[0030] As for the power collection module, it should be noted that the power collection module includes a photodetector, a signal processing circuit and an ADC converter. The photodetector is located at the laser emitting end of the laser gyroscope and is used to collect the laser power of the laser and convert it into a corresponding electrical signal. The signal processing circuit is used to adjust and process the electrical signal emitted by the photodetector and output a stable electrical signal. The ADC converter is used to convert the stable electrical signal adjusted and processed by the signal processing circuit into a digital signal and input it into the main control module.
[0031] In the specific implementation of this scheme, through high-precision photoelectric detectors and ADC converters, the system can accurately measure the output power of the laser and provide accurate data support for control. By introducing signal processing circuits and eliminating noise and interference in the signal through filtering and amplification, the stability and reliability of the system are enhanced. The analog signal is converted into a digital signal through the ADC converter, so that the system can adopt a digital control strategy, which improves the flexibility and accuracy of the control, so that after the main control module receives the accurate digital signal, it can perform calculations more effectively and generate more accurate adjustment instructions, thereby realizing accurate control of the dynamic power of the laser gyroscope, thereby ensuring the efficient, stable and accurate operation of the dynamic power supply control system of the laser gyroscope.
[0032] As for the signal processing circuit, this embodiment further describes it here, which includes an amplifier, a filter and a linear circuit. The input end of the amplifier is connected to the output end signal of the photodetector, and the amplitude of the electric signal emitted by the photodetector is amplified and adjusted. The filter is used to filter and remove noise on the amplified electric signal to ensure the stability and accuracy of the electric signal output. The linear circuit is used to condition the electric signal to ensure that the electric signal maintains its integrity and reliability during the transmission process and avoids distortion of the electric signal. It should be noted that through the coordinated work of the amplifier and the filter, the signal processing circuit can significantly improve the quality of the signal, making the signal clearer and facilitating subsequent digital conversion and processing. The introduction of the linear circuit enhances the stability of the system by maintaining the linear characteristics of the signal, ensuring the integrity and reliability of the signal during the transmission process, and the high-quality signal provides an accurate analog signal for the ADC converter. The converted digital signal can be used by the main control module for precise calculation and processing to generate more precise adjustment instructions, thereby realizing precise control of the dynamic power of the laser gyro. Furthermore, through the design and implementation of signal processing circuits, amplification, filtering and linearization processing are performed to ensure efficient, stable and precise operation of the laser gyro dynamic power supply control system, significantly improving the performance of the system.
[0033] It should be noted that the specific generation process of the preliminary adjustment instruction is: the feedback control unit calculates the power difference value according to the deviation value between the actual output power of the laser of the laser gyro and the set power recorded and collected, and obtains the preliminary adjustment instruction based on the proportional control gain; its calculation process satisfies the following:
[0034] ,
[0035] ,
[0036] in, To record the actual output power of the laser gyro, Set the output power for the laser gyro's laser, is the difference between the actual output power and the set power of the laser gyro, Preset response parameters for proportional gain, which determine the speed and degree of system response to power deviation. is the calculated preliminary adjustment instruction. In the above process, through the application of proportional control gain, the system can quickly respond to power deviation and adjust the power supply parameters in time to reduce power deviation and improve the dynamic response speed of the system. The control adjustment of proportional gain allows the system to accurately control different power deviations, thereby outputting preliminary adjustment instructions, providing a basis for subsequent feedforward control, so that the entire control system can more effectively combine feedback and feedforward control, optimize overall performance, and ultimately achieve precise adjustment of the laser output power of the laser gyroscope.
[0037] In this embodiment, the specific process of the feedforward control unit calculating and generating the adjustment instruction is as follows:
[0038] (1) The power supply module adjusts its power supply parameters based on the preliminary adjustment instructions;
[0039] (2) Based on the status parameters of the laser gyro after the power supply module adjusts the power supply parameters, the feedforward control unit calculates the adjustment instruction correction amount based on the model algorithm;
[0040] (3) The feedforward control unit calculates and generates the final control instruction based on the control instruction correction value and the preliminary control instruction given by the feedback control unit.
[0041] Based on the process of calculating and generating adjustment instructions by the above-mentioned feedforward control unit, the optimization of the dynamic power supply control of the laser gyroscope is achieved through precise power supply parameter adjustment, application of model algorithm, calculation of adjustment instruction correction amount and improvement of system stability and response speed. Specifically, the feedforward control unit combines the adjustment instruction correction amount and the preliminary adjustment instruction given by the feedback control unit to calculate and generate the final adjustment instruction, which realizes the instant response of the control system, and further considers the trend of dynamic changes of the system, realizes more precise and forward-looking control, so that the system can adapt to the working state changes of the laser gyroscope more quickly, and reduces the control error caused by response delay. At the same time, the introduction of feedforward control improves the stability of the system, so that the laser gyroscope can maintain stable performance under different working conditions, and thereby promotes the system to form a closed-loop control, greatly improving the control accuracy and efficiency, and optimizing the overall control effect.
[0042] It should be further explained that, in step (2), the status parameters of the laser gyro after the power supply parameters are adjusted based on the power supply module include the beam quality and the laser temperature of the laser, the model algorithm is an automatic encoder, and the automatic encoder includes an encoding part and a decoding part;
[0043] The encoding part is used to collect the actual status parameters of the laser gyro after the power supply module adjusts the power supply parameters as input data, and perform data encoding and compression to capture key features to output low-dimensional data;
[0044] The decoding part is used to receive the low-dimensional data output by the encoding part and output the reconstruction status parameters of the laser gyro, and then compare the difference between the reconstruction status parameters of the laser gyro and the actual status parameters of the laser gyro based on the mean square error function, and calculate the adjustment instruction correction amount according to the difference through the rule function.
[0045] It should be understood that the encoding part and the decoding part in the above embodiment are both implemented through neural networks, wherein the encoding part is responsible for compressing the input data into a low-dimensional representation, while the decoding part is responsible for restoring this low-dimensional representation to the original data, so as to ensure that the automatic encoder in the laser gyro dynamic power supply control system can accurately implement the encoding and decoding functions, and can adjust the threshold parameters and proportional constants according to the actual system requirements to achieve the best control effect.
[0046] Based on the above embodiment, it should be noted that the operation process of the automatic encoder satisfies the following:
[0047] ,
[0048] ,
[0049] ,
[0050] ,
[0051] in, is the status parameter of the laser gyro, For the encoding part The input laser gyro status parameters are compressed and encoded to output low-dimensional data. For the decoding part The laser gyro status parameters after reconstructing the output low-dimensional data, is the mean square error calculation formula, which is used to measure the difference between the reconstructed state parameters of the laser gyro and the actual state parameters of the laser gyro. is the number of samples of the actual status parameters and the reconstructed status parameters of the laser gyro, is the square of the difference between the actual status parameter and the reconstructed status parameter of the laser gyro, is the calculated adjustment instruction correction amount, , , is the proportionality constant, , is the threshold parameter of the autoencoder, which is learned through training data and is used to adjust the weight of the encoding part.
[0052] In addition, it should be noted that the threshold parameter of the automatic encoder and It can be determined by analyzing the error distribution of the training data, and defining different proportional constants corresponding to different error ranges. , , , and the proportionality constant , , It can be adjusted according to the system response requirements. For example, if the system needs to respond quickly to small errors, the , and if a stronger suppression effect on large errors is required, it can be increased . Different working conditions are simulated to observe the system response speed, and these parameters are adjusted based on the corresponding performance indicators. The above method is then used to ensure that the automatic encoder in the laser gyro dynamic power supply control system can accurately realize the encoding and decoding functions, and can adjust the threshold parameters and proportional constants according to the actual system requirements to achieve the best control effect, so that the entire control system can be used better.
[0053] In step (3), the final adjustment instruction calculation process satisfies:
[0054] ,
[0055] in, The adjustment instructions generated for the final calculation, is a proportional coefficient, which is used to adjust the response degree of the control signal and determine the influence of the adjustment command correction amount on the final adjustment command.
[0056] Based on the above embodiment, when the autoencoder is applied, it is also necessary to train it, and the training process of the autoencoder includes the following steps:
[0057] (2.1) Initialize the weight parameters of the encoding part and the decoding part;
[0058] (2.2) Using the actual status parameters of the laser gyro as training data, inputting them into the encoding part for encoding to obtain low-dimensional data;
[0059] (2.3) Inputting the encoded low-dimensional data into the decoding part, outputting the reconstructed state parameters of the laser gyro, and calculating the mean square error between the reconstructed state parameters of the laser gyro and the actual state parameters;
[0060] (2.4) Adjust the weight parameters of the encoder and decoder according to the mean square error to minimize the error;
[0061] (2.5) Repeat steps (2.2) to (2.5) until the preset number of training iterations or error threshold is reached;
[0062] (2.6) Use the validation dataset to evaluate the performance of the trained autoencoder and adjust the threshold parameters , and the proportionality constant , , In order to optimize the control effect, it should be understood that in order to ensure the generalization ability of the autoencoder and optimize the control effect, a validation data set is mentioned in this step, which contains the actual status parameters of the laser gyroscope under different working conditions. These parameters are of the same parameter type as those in the training data set, but the specific values and samples should not be used to train the model, that is, they are independent of the training data set. Therefore, the validation data and the data distribution that can reflect the actual application are used to comprehensively evaluate the performance of the model. Specifically, the validation data set should account for a certain proportion of the entire data set (actual status parameters), preferably 20%, and the validation data set should be updated regularly to reflect the latest data distribution and trends, and random sampling is used for collection and extraction.
[0063] It should be noted that, in the present embodiment, the training process of the autoencoder is the core link for realizing the dynamic power supply control of the laser gyroscope. By initializing the weight parameters of the encoding part and the decoding part and using the actual status parameters of the laser gyroscope as training data, the autoencoder learns how to effectively compress these high-dimensional data into low-dimensional representations and reconstruct the original data through the decoding process. During the training process, by calculating the mean square error between the reconstructed status parameters and the actual status parameters and adjusting the weight parameters according to the error, the autoencoder can gradually optimize its performance to minimize the reconstruction error. This process is repeated until a preset number of training iterations or an error threshold is reached.
[0064] This embodiment is different from the prior art in that it uses an independent verification data set, which not only improves the generalization ability of the automatic encoder, but also ensures that the control system can adapt to various situations in practical applications, thereby achieving precise control of the dynamic power of the laser gyroscope and improving the stability and reliability of the system.

Specifically, the method includes the following steps: S1, starting the power supply module to supply power to the laser of the laser gyroscope, and at the same time, the power acquisition module starts to record and collect the output power of the laser of the laser gyroscope; S2, the main control module receives the actual output power data of the laser of the laser gyroscope collected by the power acquisition module, and compares it with the set power to calculate the power difference; S3, the feedback control unit calculates the preliminary adjustment instruction according to the power difference and the proportional control gain; S4, the power supply module adjusts the power supply parameters according to the preliminary adjustment instruction; S5, the feedforward control unit The system collects the state parameters of the laser gyro after the power supply parameters are adjusted, including the beam quality of the laser and the laser temperature, calculates the adjustment instruction correction amount through the trained automatic encoder model algorithm, and combines the adjustment instruction correction amount and the preliminary adjustment instruction to calculate and generate the final adjustment instruction; S6, the main control module sends the final adjustment instruction to the power supply module, and the power supply module accurately adjusts the power supply parameters according to the final adjustment instruction; S7, the system continuously monitors the laser output power of the laser gyro, and cyclically executes steps S2 to S6 to achieve stable control of the dynamic power of the laser gyro and ensure the long-term stability and accuracy of the control system.
