Description

TECHNICAL FIELD

[0002] For a variety of single-component magnetic probes with a suspended structure, when measuring a vertical magnetic field, the magnetic probe will rotate involuntarily due to the suspended structure during the measurement. Experiments show that the measured magnetic field is different when the magnetic probe rotates 360 degrees, and there is always a turning error. This is due to the limitation of the processing precision of the suspended structure. When measuring the vertical magnetic field, the magnetic field measured by the magnetic probe is not the true vertical magnetic field value, but a magnetic field value with a certain angle. No matter how precise the suspended structure on the magnetic probe is, the measurement will always have errors. SUMMARY

[0008] S4: intelligent algorithm optimization, combined with a machine learning algorithm, the model is trained through historical debugging data, the best adjustment parameter is intelligently predicted, unnecessary repeated operations in the debugging process are reduced, and the adjustment path is optimized, so that H max -H min is faster into the qualified range;

[0009] S5: multi-point calibration: multiple measurement points are added, not limited to four directions, combined with a three-dimensional vector magnetic field sensor, a full-range magnetic field measurement and analysis are performed to reduce local errors and further optimize the accuracy and stability of the overall magnetic field detection.

[0010] Further, the S2 specifically comprises:

[0011] S21: Place the overhanging magnetic probe on the debugging dedicated parallel ring, and connect the magnetometer;

[0012] S22: Rotate the parallel ring 360 degrees, measure the magnetic field value of the magnetic probe in four directions, find a maximum value H max and a minimum value H min , then subtract the two values to get a difference value H max -H min , then compare this value with the specified turning error H of the magnetometer itself, if the value is greater than H, adjust the non-magnetic copper screw under the magnetic probe repeatedly until H max -H min <H, at this time, it is considered that the magnetic field value measured by the magnetic probe is qualified.

[0013] Another object of the present application is to provide a single-component magnetic probe turning error adjustment system based on the single-component magnetic probe turning error adjustment method, which specifically comprises:

[0014] An additional module is used to add a non-magnetic copper material under the magnetic probe, and two rotatable adjustable copper screws are designed in the mutually orthogonal directions, which can be advanced and retreated; through a special debugging device such as a parallel ring, the turning error is reduced to a qualified range;

[0015] An automatic adjustment device introduction module is connected with the additional module, which automatically calculates and adjusts H max and H min difference by using a stepping motor to drive the rotation and fine adjustment of the copper screw, combined with real-time feedback of sensor data, so that the adjustment process is more accurate and does not require manual repeated operation, thereby improving efficiency and accuracy;

[0016] An intelligent algorithm optimization module is connected with the automatic adjustment device introduction module, which combines machine learning algorithms, trains models through historical debugging data, intelligently predicts the best adjustment parameters, reduces unnecessary repeated operations in the debugging process, and optimizes the adjustment path, so that H max -H min enters the qualified range more quickly;

[0017] A multi-point calibration module is connected with the intelligent algorithm optimization module, which increases multiple measurement points, not limited to four directions, combines a three-dimensional vector magnetic field sensor, and performs omnidirectional magnetic field measurement and analysis to reduce local errors and further optimize the accuracy and stability of the overall magnetic field detection.

[0018] Another object of the present application is to provide a computer device, characterized in that the computer device comprises a memory and a processor, the memory stores a computer program, and the computer program is executed by the processor to enable the processor to perform the steps of the method for adjusting the yaw error of a single-component magnetic probe.

[0021] In combination with the above technical solutions and the technical problems solved, the technical solution of the present application has the following advantages and positive effects:

[0022] Firstly, the present application reduces interference and error: the introduction of non-magnetic copper can effectively reduce the influence of external magnetic field on the magnetic probe and reduce the measurement error caused by magnetic interference. The two copper screws which can rotate in orthogonal directions and can be adjusted forward and backward provide the possibility for accurate adjustment, and the error caused by installation or environmental factors can be further reduced through fine adjustment.

[0023] The present application improves the measurement accuracy: the reduction of yaw error can accurately adjust the measurement direction of the magnetic probe by using special debugging devices such as parallel rings, thereby significantly reducing the yaw error and making the measurement result more accurate and reliable; the overall performance is improved: by comprehensively applying the above-mentioned technologies, the overall measurement accuracy of the magnetic probe can be significantly improved, so that it can maintain stable measurement performance in complex environments.

[0024] Secondly, the technical solution of the present application solves the problems of inaccurate yaw error adjustment, low efficiency, and error caused by dependence on manual adjustment of the single-component magnetic probe in the prior art. The yaw error adjustment of the traditional magnetic probe mainly relies on manual operation, which not only has a complicated adjustment process and limited accuracy, but also needs to be repeatedly mechanically fine-tuned, resulting in long debugging time, low efficiency, and being easily disturbed by human factors, which cannot meet the demand of high-precision magnetic field detection.

[0025] The application provides a high-precision adjustment method with rotatable fine adjustment by adding a non-magnetic copper support plate and a mutually orthogonal copper screw adjustment system below the magnetic probe. This design not only greatly simplifies the adjustment operation, but also significantly improves the flexibility and stability of the probe adjustment. Further introduction of a stepper motor and a real-time sensor feedback system realizes automatic and accurate steering difference adjustment. The stepper motor controls the copper screw rotation in real time through sensor data, automatically adjusts the Hmax and Hmin difference, achieves rapid and efficient adjustment effect, and avoids repeated debugging and error accumulation in manual operation.

[0026] In addition, the application combines intelligent algorithms and a multi-point calibration system, optimizes the adjustment path through a machine learning model, automatically predicts the best adjustment parameters, significantly reduces unnecessary repeated operations in the adjustment process, and speeds up the speed of Hmax-Hmin difference entering the qualified range. Multi-point measurement and omnidirectional calibration realized by a three-dimensional vector magnetic field sensor further reduce local errors and enhance the accuracy and stability of measurement. This technical solution has wide application prospects in high-precision magnetic detection fields such as magnetic field measurement, geomagnetic detection and scientific experiments, and provides a reliable and effective solution for the automation and high-precision adjustment of magnetic probes, promoting significant progress in the technical level of related fields.

[0032] In order to make the purpose, technical scheme and advantages of the application clearer, the application will be further described in detail below with examples. It should be understood that the specific examples described herein are only used to explain the application and not to limit the application.

[0033] The present scheme proposes a systematic method for precise adjustment of the steering difference of a magnetic probe by adding a non-magnetic copper material and a rotating adjustable copper screw below the magnetic probe. The specific steps are as follows:

[0034] Step 1: Installation of non-magnetic copper material support

[0035] 1.1 Selection and installation of non-magnetic copper material support plate

[0036] A non-magnetic copper material support plate is installed below the magnetic probe. The purpose of this support plate is to ensure that the magnetic probe is not disturbed by external magnetic fields during adjustment, maintaining the stability of the probe itself. At the same time, the non-magnetic copper material can reduce the influence of external magnetic fields on the adjustment accuracy of the probe, improving the reliability of the adjustment results.

[0037] 1.2 Fixing of support plate and probe

[0038] Stably connect the non-magnetic copper support plate with the magnetic probe to ensure that the support plate can withstand the fine adjustment pressure of the copper screw. The position and height of the support plate should be able to cover the entire steering adjustment range of the probe while maintaining the vertical stability of the probe.

[0039] Step 2: Design of orthogonal copper screw adjustment system

[0040] 2.1 Orthogonal direction selection

[0041] At the bottom of the non-magnetic copper support plate, two mutually orthogonal adjustment directions, X-axis and Y-axis, are set according to the structure and adjustment requirements of the probe. These two directions can ensure the inclination adjustment of the probe in any horizontal plane.

[0042] 2.2 Selection and installation of copper screw

[0043] Install a copper screw in each of the X-axis and Y-axis directions. The copper screw needs to have a rotating adjustment function and be able to accurately control small displacements. The screw material is made of high-strength, wear-resistant non-magnetic copper to ensure its stability and non-magnetic interference during long-term adjustment. At the same time, the rotation accuracy of the screw should reach the micron level to ensure the accuracy of small-angle adjustment.

[0044] 2.3 Adjustability of screw

[0045] Each copper screw can be rotated in two directions (i.e., clockwise and counterclockwise), thereby realizing forward and backward adjustment to meet the small steering difference adjustment requirements of the probe. By rotating the copper screw, the probe can be fine-tuned to gradually reduce the steering deviation of the probe.

[0046] Step 3: Manual adjustment of steering difference

[0047] 3.1 Preliminary adjustment and testing

[0048] Using special debugging devices such as parallel rings, place the probe on the support plate and start the preliminary debugging. First, use copper screws for manual adjustment to make the angle and horizontal position of the probe close to the predetermined value. Use tools such as parallel rings to detect the change of steering difference during adjustment, and gradually reduce the steering difference by adjusting the forward and backward rotation of the copper screw.

[0049] 3.2 Fine adjustment to the qualified range

[0050] Continue to refine the angle of the probe by adjusting the copper screws on the X and Y axes to reduce the difference between Hmax and Hmin. After controlling the steering difference within the qualified range, lock the final position of the copper screw to ensure the stability of the probe.

[0051] Step 4: Introduction of automatic adjustment device

[0052] 4.1 Installation of stepper motor control system

[0053] Install stepper motor drive devices on the copper screws, connect the stepper motor to the control system to realize automatic control of the screw rotation. The precision and response speed of the stepper motor should meet the small amplitude requirement of adjustment to achieve high-precision adjustment.

[0054] 4.2 Sensor feedback and automatic adjustment

[0055] Install real-time sensors to monitor the Hmax and Hmin difference of the probe, transmit the measurement data from the sensors to the control system, and calculate the steering difference offset in real time. The control system automatically calculates the best adjustment angle based on the difference, adjusts the rotation of the copper screw through the stepper motor, and gradually reduces the Hmax-Hmin difference to within the standard range.

[0056] Step 5: Intelligent optimization and multi-point calibration

[0057] 5.1 Intelligent algorithm optimization

[0058] Use machine learning algorithms to train models based on historical debugging data to automatically predict the best adjustment parameters in different situations and reduce unnecessary repetitive operations. The intelligent algorithm will dynamically adjust the adjustment path based on feedback data during the debugging process, making the adjustment more efficient and the Hmax-Hmin difference faster to reach the standard range.

[0059] 5.2 Multi-point measurement and three-dimensional calibration

[0060] To further improve the overall debugging accuracy of the probe, add multiple measurement points during adjustment, not just four directions. Combine three-dimensional vector magnetic field sensors to realize magnetic field measurement and analysis of the probe in multiple directions, further reduce local errors, and optimize the stability and accuracy of overall measurement.

[0061] The adjustment scheme can effectively reduce the steering difference of the single-component magnetic probe, improve the measurement accuracy and stability of the probe in a complex magnetic field environment. Through the combination of the stability of the non-magnetic copper support structure, the adjustable copper screw, the stepping motor control, the intelligent optimization algorithm and the multi-point calibration technology, an efficient and automated magnetic probe steering difference adjustment process is realized.

[0062] As shown in Figure 1 The embodiment of the present application provides a steering difference adjustment method of a single-component magnetic probe, which comprises:

[0063] S1: A non-magnetic copper material is attached below the magnetic probe, and two rotatable and adjustable copper screws are designed in mutually orthogonal directions, which can advance and retreat;

[0064] S2: Through a special debugging device such as a parallel ring, the steering difference is reduced to a qualified range;

[0065] S3: An automatic adjustment device is introduced, and the rotation and fine adjustment of the copper screw are driven by a stepping motor, and the H max and H min difference is automatically calculated and adjusted by combining real-time feedback sensor data, so that the adjustment process is more accurate and does not require repeated manual operations, thereby improving efficiency and accuracy;

[0066] S4: Intelligent algorithm optimization, combined with machine learning algorithm, the model is trained through historical debugging data, the best adjustment parameter is intelligently predicted, unnecessary repeated operations in the debugging process are reduced, and the adjustment path is optimized, so that H max -H min is faster into the qualified range;

[0067] S5: Multi-point calibration: multiple measurement points are added, not limited to four directions, combined with a three-dimensional vector magnetic field sensor, for omnidirectional magnetic field measurement and analysis to reduce local errors and further optimize the accuracy and stability of the overall magnetic field detection.

[0068] The S2 specifically comprises:

[0069] S21: Place the overhanging magnetic probe on the debugging special parallel ring and connect the magnetometer;

[0070] S22: Rotate the parallel ring 360 degrees, measure the magnetic field values of the magnetic probe in four directions, find a maximum value H max and a minimum value H min , then subtract the two values to get a difference value H max -H minThen compare this value with the turning error H specified value of the magnetometer itself, if the value is greater than H specified value, at this time adjust the non-magnetic copper screw below the magnetic probe, repeat many times, until H max -H min <H specified value, at this time, it is considered that the magnetic field value measured by the magnetic probe is qualified.

[0071] The embodiment of the application provides a single-component magnetic probe turning error adjustment system based on the single-component magnetic probe turning error adjustment method, and the system specifically comprises:

[0072] An additional module 1 is used for adding a non-magnetic copper material below the magnetic probe, designing two rotatable and adjustable copper screws in mutually orthogonal directions, which can advance and retreat; and a special debugging device such as a parallel ring is used to reduce the turning error to a qualified range;

[0073] An automatic adjustment device introduction module 2 is connected with the additional module 1, and a stepping motor is used to drive the rotation and fine adjustment of the copper screw, and the H max and H min difference is automatically calculated and adjusted by combining the real-time feedback sensor data, so that the adjustment process is more accurate and does not require manual repeated operation, thereby improving the efficiency and precision;

[0074] An intelligent algorithm optimization module 3 is connected with the automatic adjustment device introduction module 2, combines a machine learning algorithm, trains a model through historical debugging data, intelligently predicts the best adjustment parameter, reduces unnecessary repeated operation in the debugging process, and optimizes the adjustment path, so that H max -H min enters the qualified range more quickly;

[0075] A multi-point calibration module 4 is connected with the intelligent algorithm optimization module 3, increases multiple measurement points, is not limited to four directions, combines a three-dimensional vector magnetic field sensor, and performs omnidirectional magnetic field measurement and analysis to reduce local errors and further optimize the accuracy and stability of the overall magnetic field detection.

[0076] The single-component magnetic probe turning error adjustment method improves the efficiency and precision of the magnetic probe debugging through innovative mechanical and intelligent adjustment steps. First, in step S1, in order to realize controllability of adjustment, a support structure of non-magnetic copper material is added below the magnetic probe, and rotatable copper screws are designed in two mutually orthogonal directions. These copper screws not only can advance and retreat, but also can rotate and fine adjust the position of the magnetic probe, so that the adjustment is more flexible. This design ensures the operability of the mechanical structure and lays a foundation for subsequent automatic adjustment.

[0077] In step S2, the steering difference is gradually reduced to the qualified range by using special debugging devices such as parallel rings. These debugging devices can accurately measure the steering difference of the probe, ensuring the accuracy of the difference during adjustment. The control of the steering difference is to make the magnetic probe not be affected by unnecessary deviation and interference during measurement, so as to improve the accuracy of the measurement result. The adjustment in this step is mainly completed in a manual mode, which ensures the basic adjustment effect and lays a foundation for further accurate automatic adjustment.

[0078] In steps S3 and S4, the system introduces automatic adjustment devices, combining stepper motors and intelligent algorithms to achieve more accurate automatic adjustment. The stepper motor drives the copper screw to rotate, and automatically calculates and adjusts the difference between Hmax and Hmin through real-time feedback of sensor data, so that the adjustment process does not require repeated manual operation. The intelligent algorithm combines machine learning to train the model through historical debugging data, predicts the optimal adjustment parameters and optimizes the adjustment path, so that the difference between Hmax and Hmin enters the qualified range faster, significantly improving the adjustment efficiency and accuracy and reducing the workload of manual debugging.

[0079] Finally, in step S5, in order to ensure the overall calibration of the probe, a multi-point measurement calibration process is added. Using a three-dimensional vector magnetic field sensor, the system can make omnidirectional measurement and analysis of the magnetic field at multiple measurement points. This multi-point calibration not only improves the coverage of the measurement, but also significantly reduces local errors, optimizing the accuracy and stability of the overall magnetic field detection. This multi-point calibration design ensures the measurement stability of the magnetic probe in complex magnetic field environments, making it suitable for high-precision magnetic field detection requirements.
