Abstract
Description
Technical Field
[0001] This invention relates to the field of angular displacement monitoring technology, and in particular to an angular displacement monitoring method, device, and storage medium based on an coded angle disk. Background Technology
[0002] In fields such as wind turbine generator sets and large equipment assembly, the preload of high-strength bolts is a key factor in ensuring the safe operation of equipment. It not only relates to the tightness and stability of bolted connections but also directly affects the safety and reliability of the entire equipment system. The preload and looseness of bolts directly affect the safety and stability of equipment operation. The standard, primarily derived from the "90 / 10 rule" in engineering practice—a practical rule of thumb for bolt tightening—states that approximately 90% of the torque is consumed by friction when tightening a bolt, and only 10% is converted into effective preload. Therefore, only about 10% of the torque is converted into effective preload, while the remaining 90% is consumed by friction. If the preload changes by more than 10%, it indicates that the connection may have loosened and needs to be retightened to ensure reliability. The relative rotation angle of the bolt or nut is one of the key parameters for judging its tightness. Currently, some technical solutions for angular displacement monitoring utilize bolt pre-tightening devices to perform basic pre-tightening operations. However, these solutions primarily rely on manual observation and measurement of bolt loosening to determine the bolt's loosening angle. Since the 10% warning rate for loose bolts or nuts in wind turbines is mostly between 2 and 4 degrees, it is difficult to identify with the naked eye. This not only results in low intelligence and efficiency in determining angular displacement monitoring results but also leads to large identification errors and low accuracy in angular displacement monitoring.
[0003] Therefore, it is particularly important to improve the intelligence and efficiency of angular displacement monitoring, as well as the accuracy and reliability of angular displacement monitoring calculations. Summary of the Invention

[0064] In this embodiment of the invention, optionally, the determination of bolt fault early warning parameters corresponding to the component under test based on preset bolt fault conditions and angular displacement monitoring results may include: Based on the preset bolt failure conditions and angular displacement monitoring results, the warning status of the component under test is determined, and the corresponding bolt failure warning parameters of the component under test are determined based on the warning status of the component under test.
[0065] In this embodiment of the invention, optionally, the warning state of the component under test may include a first warning state or a second warning state, wherein the first warning state may include a slightly loose state; and the second warning state may include a severely loose state. Further, when the warning state of the component under test is the first warning state, a looseness prompt message corresponding to the component under test can be generated and sent to the administrator's terminal to remind the administrator; when the warning state of the component under test is the second warning state, component processing parameters corresponding to the second warning state are generated to perform a component tightening operation or a component replacement operation on the component under test.
[0066] In this embodiment of the invention, optionally, for example, the bolt fault warning parameters corresponding to the component under test may include a set of parameters for defining the warning intensity and response requirements, including warning level, response priority, processing time limit, and fault risk description.

[0070] It is evident that implementation Figure 2The described bolt angle meter method based on an coded angle disk can acquire real-time scene information corresponding to the component under test and determine the corresponding angle verification threshold. Based on the angular displacement monitoring results and the angle verification threshold, it determines the angle detection state and judges whether the bolt fault conditions are met. If met, it determines the bolt fault early warning parameters corresponding to the component under test, generates early warning processing parameters, and executes matching early warning processing operations. By acquiring real-time scene information of the scene where the component under test is located, it dynamically matches differentiated angle verification thresholds, avoiding misjudgment or missed judgment problems under complex working conditions with fixed thresholds. It also helps improve the intelligence of bolt state detection and the adaptability between the bolt and the current scene. If the angle detection state... When bolt failure conditions are met, the system can intelligently determine the corresponding bolt failure warning parameters for the component under test. This improves the intelligence and efficiency of determining these parameters, as well as their accuracy and reliability. Furthermore, it enhances the operational safety of the component under test, preventing errors caused by bolt failures that could lead to equipment malfunctions. By providing early warnings of potential bolt failures, it avoids equipment downtime and safety accidents resulting from bolt failure, indirectly reducing economic losses and demonstrating significant economic benefits. Compared to standardized warnings, customized parameters allow the warning response to better meet actual needs, avoiding resource waste and further improving the safety and reliability of bolt operation.
[0071] In an optional embodiment, the data acquisition results include several digital signal acquisition results, wherein filtering out target detection data from the data acquisition results includes: Based on the data acquisition results, determine the acquisition data order corresponding to the digital signal acquisition results, where the acquisition data order includes the acquisition order corresponding to all digital signal acquisition results; Determine the digital signal difference parameters corresponding to the data acquisition order, and determine whether there are any target abnormal parameters among all digital signal difference parameters that do not meet the predetermined data acquisition logic. The digital signal difference parameters include the digital bit difference parameters between every two digital signal acquisition results in the data acquisition order. When it is determined that there are target abnormal parameters in all digital signal difference parameters that do not meet the predetermined data acquisition logic, all target abnormal parameters are removed from the data acquisition results, and target detection data is generated based on the removed data acquisition results. Among these, determining whether there are any target abnormal parameters among all digital signal difference parameters that do not meet the pre-determined data acquisition logic includes: Determine whether there is a target signal difference parameter among all digital signal difference parameters whose digital bit change is greater than or equal to a preset change threshold. When it is determined that there is a target difference parameter among all digital signal difference parameters whose digital bit change is greater than or equal to a preset change threshold, it is determined that there is a target abnormal parameter among all digital signal difference parameters that does not meet the predetermined data acquisition logic; when it is determined that there is no target difference parameter among all digital signal difference parameters whose digital bit change is greater than or equal to a preset change threshold, it is determined that there is no target abnormal parameter among all digital signal difference parameters.
[0072] In this optional embodiment, the data acquisition results may include a set of raw signals acquired by the acquisition device corresponding to the component under test according to a preset acquisition period, including several digital signal acquisition results.
[0073] In this optional embodiment, the order of the acquired data corresponding to the digital signal acquisition results can be a sequence formed by arranging the acquisition timestamps in ascending order, where each element in the sequence is a single digital signal acquisition result.
[0074] In this optional embodiment, the digital signal difference parameter corresponding to the data acquisition order may include the difference characteristics of two adjacent digital signal acquisition results in the data acquisition order, and may further include the amount of digital bit change between two adjacent 4-bit binary codes.
[0075] In this optional embodiment, it is further possible to terminate the process when it is determined that all digital signal difference parameters have target abnormal parameters that satisfy the predetermined data acquisition logic.
[0076] In this optional embodiment, optionally, removing all target anomaly parameters from the data acquisition results and generating target detection data based on the removed data acquisition results may include: If it is determined that there are target abnormal parameters, all marked target abnormal parameters are extracted, all target abnormal parameters are removed from the data acquisition results, and based on the data acquisition results after removal, the remaining digital acquisition results are reordered according to the original acquisition timestamp order to form a continuous and valid data sequence. Perform integrity verification on the reordered valid data sequence, obtain the integrity verification result, and determine whether the integrity verification result meets the preset integrity verification conditions. When it is determined that the integrity verification result meets the preset integrity verification conditions, target detection data is generated based on the valid data sequence; If the integrity check result is determined to be inconsistent with the preset integrity check conditions, the data acquisition operation is re-executed.
[0077] In this optional embodiment, the preset change threshold can optionally be 1; further, the preset change threshold is a fixed threshold for judging whether the digital signal is abnormal, with a value of 1 bit, and the threshold is based on the design logic of the encoding switching sequence.
[0078] In this optional embodiment, for example, any two adjacent digital signals in the switching sequence have only one digital bit state difference. The digital signals are identified strictly in this sequence during the rotation of the angle wheel. If there are two digital bit state differences, it is determined whether there is a signal target difference parameter in the digital signal difference parameter where the digital bit change is greater than or equal to a preset change threshold.
[0079] As can be seen, implementing this optional embodiment can determine the order of collected data based on the data acquisition results, determine the digital signal difference parameters corresponding to the order of collected data, and determine whether there are target abnormal parameters that do not meet the preset data acquisition logic. If there are, the target abnormal parameters are removed to generate target detection data. It can accurately identify and remove abnormal parameters that change multiple digital bits at the same time through the change of digital bits. This method avoids abnormal signals from entering the calculation process, providing a precise data foundation for subsequent bolt angle calculations. It also transforms data acquisition logic into quantifiable threshold judgment rules for changes, eliminating the need for manual signal validity assessment and completely avoiding human experience bias. This standardizes and automates the screening process, significantly improving the consistency and reliability of the screening results. Abnormal signals with simultaneous changes in multiple digits can directly lead to angle mapping matching errors, resulting in angle calculation deviations. By pre-screening and eliminating abnormal parameters, the error propagation path is cut off at the source, making subsequent encoding matching and angle calculation based on target detection data more accurate. This improves the accuracy and reliability of the screened target detection data, as well as the intelligence and efficiency of the screened target detection data. Furthermore, it enhances the intelligence and efficiency of measuring bolt loosening angles, improving the accuracy and reliability of angle calculations. Finally, it enables intelligent measurement and calculation of bolts or nuts based on an angle dial, further improving the intelligence and efficiency of measuring bolt or nut loosening angles, as well as the accuracy and reliability of the measured bolt or nut loosening angles.
[0080] In another optional embodiment, before determining the encoded detection result of the component under test based on the target detection data, component attribute information, and a pre-determined measurement mapping relationship, the method further includes: Obtain the reference attribute information corresponding to several reference components. Based on all the reference attribute information and the angle detection disk, determine the rotation correspondence between each reference component and the angle detection disk. The rotation correspondence includes the relationship between the actual rotation angle value of each reference component and the angle measurement value of the angle detection disk. Based on the rotational correspondence between all reference components and the angle detection disk, a differentiated angle parameter mapping table is generated, and a measurement mapping relationship is generated based on the differentiated angle parameter mapping table.
[0081] In this optional embodiment, the reference component may optionally include a standard bolt sample for calibrating the correlation between the angle detection disc and bolt rotation, covering bolts with nominal diameters such as M8, M10, M12, M16, M20, and M24. Furthermore, the reference component may also include a reference nut sample.
[0082] In this optional embodiment, the reference attribute information corresponding to the reference component may include a set of parameters for characterizing the core characteristics of each reference component. The reference attribute information corresponding to the reference component may include nominal diameter, thread pitch, bolt head thickness, material yield strength, and bolt design preload torque.
[0083] In this optional embodiment, the determination of the rotational correspondence between each reference component and the angle detection disk based on all reference attribute information and the angle detection disk may include: For each reference component, based on the reference attribute information of the reference component and the angle measuring disk, the reference component is fixed in the angle measuring disk. Based on the real-time rotation parameters of the reference component and the real-time angle measurement parameters corresponding to the angle measuring disk, the rotation correspondence between the reference component and the angle detection disk is generated.
[0084] In this optional embodiment, the actual rotation angle value may include the true rotation angle of the reference component under controllable torque, which may be measured by a high-precision calibration device and used as a standard reference value for angle mapping; the angle measurement value of the angle detection disk may include the angle value converted from the coded position when the angle detection disk rotates synchronously with the reference component.
[0085] In this optional embodiment, the process of generating a differentiated angle parameter mapping table based on the rotational correspondence between all reference components and the angle detection disk, and generating a measurement mapping relationship based on the differentiated angle parameter mapping table, may include: Based on the rotational correspondence between all reference components and the angle detection disk, a differentiated angle parameter mapping table is generated from the structured data set categorized according to the specifications of each reference component. Measurement mapping relationships are then generated based on the differentiated angle parameter mapping table. Each reference component's specification corresponds to a unique mapping table, and the fields in the table include reference number, nominal diameter, coded position number, coded information, angle measurement value, and standard rotation angle.
[0086] In this optional embodiment, the measurement mapping relationship may include methods to guide the data acquisition unit to quickly match the angle parameters corresponding to the component under test during actual detection.
[0087] As can be seen, implementing this optional embodiment can acquire several reference attribute information, determine the correspondence between each reference component and the angle detection disk based on the reference attribute information and the angle detection disk, and generate a differentiated angle parameter mapping table to generate a measurement mapping relationship. It can determine the rotation correspondence between the actual rotation angle of the bolt and the angle disk measurement value one by one based on the specification information of different bolts to be tested and in combination with the angle detection disk. Furthermore, it can ensure the authenticity and accuracy of the data in the differentiated mapping table based on the association relationship of each bolt specification, providing highly reliable data support for coded detection results and bolt angle calculation. It can also acquire the reference attribute information to be tested in batches, generate rotation correspondences and differentiated mappings in batches. This table helps improve the intelligence and efficiency of generating measurement mapping relationships, and establishes an independent angle association system for each bolt specification through a differentiated angle parameter mapping table. The corresponding mapping relationship can be quickly retrieved through the specification identifier in the component attribute information, which in turn helps improve the accuracy and reliability of filtering target detection data, as well as the intelligence and efficiency of filtering target detection data. Furthermore, it helps improve the accuracy and reliability of angle calculation, and further enables intelligent measurement and calculation of bolts or nuts based on the angle plate, which helps improve the intelligence and efficiency of measuring the loosening angle of bolts or nuts, as well as the accuracy and reliability of measuring the loosening angle of bolts or nuts.
[0088] In yet another optional embodiment, when the component under test includes bolts, after filtering out the target detection data from the data acquisition results, the method further includes: Determine whether fracture state data exists in all target detection data. When fracture state data is found to exist in all target detection data, perform data verification operation on all fracture state data to obtain data verification results. The data verification results include the data quantity verification result and the data continuity verification result of fracture state data. Determine whether the data verification results meet the preset fracture judgment conditions; When the data verification result is determined to meet the preset fracture judgment conditions, the component under test is determined to be in a bolt fracture state, and fracture warning parameters matching the bolt fracture state are generated.
[0089] In this optional embodiment, the determination of whether there is broken state data in all target detection data may include: traversing all hexadecimal storage location codes in the target detection data, matching each code to see if it is 8000, and simultaneously verifying whether the corresponding 4-bit binary code is 0000. If both conditions are met, it is marked as broken state data; if at least one marked broken state data exists after traversal, output that broken state data exists; otherwise, output that broken state data does not exist. Further, it can be represented by a single hexadecimal 0, with 0h representing binary 0000. The specific representation method is not specifically limited in this embodiment of the invention.
[0090] In this optional embodiment, the above-mentioned data verification operation on all fracture state data to obtain the data verification result may include: Determine the number of fracture data corresponding to the fracture state data, and determine whether the number of fracture data is greater than or equal to a preset fracture data number threshold to obtain the first judgment result; Extract the acquisition timestamps of all fracture state data, arrange them in ascending order to form a time series, calculate the time interval between two adjacent data points, and determine whether the time interval is greater than or equal to a preset time interval threshold to obtain a second judgment result; Based on the first and second judgment results, the data verification results are obtained.
[0091] In this optional embodiment, the determination of whether the data verification result meets the preset fracture determination condition may include: When the first judgment result indicates that the number of fracture data is greater than or equal to the preset fracture data number threshold, or the second judgment result indicates that the time interval is greater than or equal to the preset time interval threshold, the data verification result indicates that the fracture state data does not meet the preset fracture judgment condition. When the first judgment result indicates that the number of fracture data is less than a preset fracture data number threshold and the second judgment result indicates that the time interval is less than a preset time interval threshold, the data verification result indicates that the fracture state data meets the preset fracture judgment conditions.
[0092] In this optional embodiment, optionally, for example, the total number of fracture state data entries is counted. If the total number of data entries is greater than a preset fracture data quantity threshold, it is determined that the preset fracture judgment condition is not met. If the total number of data entries is less than or equal to the preset fracture data quantity threshold, it is determined that the preset fracture judgment condition is met. If the timestamps of the fracture state data are 10:00:00.000, 10:00:00.005, 10:00:00.010, and 10:00:00.015, with a time interval of 5ms and a continuous duration of 20ms, the T_th requirement is met, and it is determined to be continuously compliant. The data verification result output may include combining the two verification results to generate the final data verification result. If the total number of data entries is less than or equal to the preset fracture data quantity threshold and the timestamps of the fracture state data are continuously compliant, the data verification result is that the preset fracture judgment condition is met.
[0093] As can be seen, implementing this optional embodiment can determine whether fracture state data exists in all target detection data. If it does, a data verification operation is performed on all fracture state data to obtain the data verification result and determine whether the data verification result meets the preset fracture judgment condition. If it does, the component under test is determined to be in a bolt fracture state and a corresponding fracture warning parameter is generated. This can accurately determine the fracture state and avoid false alarms and missed alarms. It can also improve the accuracy and reliability of the judgment through multi-dimensional data verification methods, and further improve the accuracy and reliability of data verification based on the comprehensiveness of the data verification dimensions. It can also generate exclusive warning parameters that accurately match the fracture state after confirming bolt fracture, which is conducive to timely and accurate early warning of bolt fracture, improving the efficiency and intelligence of risk response. Furthermore, the adaptability of the method in complex environments can be improved through software logic optimization, ensuring that the fracture judgment is not affected by the environment. The generated fracture warning parameters are deeply matched with the bolt fracture state, which can directly guide maintenance personnel to take precise handling measures, avoid confusion in maintenance decisions, improve the efficiency and accuracy of fault handling, and further improve the safety and reliability of bolts and corresponding equipment operation.

Determine the detection measurement difference based on the coding position difference and the reference angle difference. The coding position difference may include the sequence difference between the current coding position and the reference coding position, and the reference angle difference may include the angle difference corresponding to the change in coding position. Based on the detection and measurement difference, the core parameters of the actual position of the coded signal of the component under test are determined, and the corresponding coded positioning parameters of the component under test are determined according to the core parameters of the actual position of the coded signal of the component under test; wherein, the core parameters of the actual position of the coded signal of the component under test may include the actual coded position, the effective coded change amount, and the positioning reliability.

Based on the localization of the encoded signal, the encoded detection result of the component under test is determined. The encoded detection result is used to characterize the final result of the encoded signal state and associated angle of the component under test. The encoded detection result includes encoded position information.
[0098] In this optional embodiment, the coding detection result may also include bolt status identifier, bolt valid coding information, and angle detection parameters corresponding to the angle detection disc.
[0099] In this optional embodiment, optionally, for example, in the retrieved mapping table subset, the angle parameters, scene correction coefficients, and relative angles within the area corresponding to the valid encoded signal in the target detection data are searched. If the hexadecimal storage location code of the valid encoded signal is 8000 and the EPC configuration location value is 06XX, it is determined to be a bolt breakage state. If the hexadecimal storage location code of the valid encoded signal is 8001 to 800F (excluding 8002, 8008, and 800A), and the encoding sequence conforms to the "sequential change or alternating position jump" rule, it is determined to be a bolt loose state. If the encoded signal alternates between 8000 and other valid codes, or the EPC configuration location value is 0000, it is determined to be a sensor fault state. If the representative value of the valid encoded signal shows alternating position jumps (such as 0 directly jumping to 3), it is determined to be an abnormal encoding sequence, and the state corresponding to the valid code of the previous cycle is maintained.
[0100] As can be seen, implementing this optional embodiment can determine the measurement mapping parameters matching the component under test in the measurement mapping relationship based on the component attribute information and the measurement mapping relationship, calculate the detection measurement difference between the target detection data and the measurement mapping parameters, and determine the coded positioning parameters. Based on the detection measurement difference, the corresponding coded positioning parameters of the component under test are determined, and based on the coded positioning parameters, the coded signal matching the coded positioning parameters is determined in the angle detection disk, thereby determining the coded detection result of the component under test. This allows for targeted matching of specific measurement mapping parameters from the measurement mapping relationship based on the attribute information of the component under test, avoiding matching deviations caused by sharing parameters between bolts of different specifications. It makes the mapping between the code and the angle more closely match the characteristics of the component under test, which is beneficial to improving matching accuracy and reliability. Furthermore, by calculating the detection measurement difference between the target detection data and the measurement mapping parameters... The difference provides precise data support for coding positioning, which helps improve the accuracy and reliability of determining coding positioning parameters and improves coding positioning accuracy. The coding detection result integrates multi-dimensional information such as coding position, signal identifier, actual angle, and validity identifier. It not only clarifies the current coding status of the bolt, but also provides complete basic data for subsequent bolt angle calculation. This helps improve the accuracy and reliability of subsequent coding detection results for the parts under test, as well as the intelligence and efficiency of determining the coding detection results for the parts under test. Furthermore, it helps improve the accuracy and reliability of angle calculation, and further enables intelligent measurement and calculation of bolts or nuts based on the angle plate. This helps improve the intelligence and efficiency of measuring the loosening angle of bolts or nuts, as well as the accuracy and reliability of measuring the loosening angle of bolts or nuts.

The data conversion operation includes converting the valid encoding signal into a 4-bit binary encoding conversion operation. Based on the target digital signal, a unique identifier for the position of the component under test on the angle detection disk is determined, and the target position identifier corresponding to the component under test is determined according to the unique position identifier.
[0103] In this optional embodiment, the above-mentioned determination of target transformation parameters matching the target location identifier based on the target location identifier, and determination of the angle calculation value of the component under test based on the target transformation parameters and a pre-determined angle calculation coefficient, may include: Based on the target location identifier, the basic angle transformation parameters corresponding to the target location identifier are determined, and the target transformation parameters are determined according to the basic angle transformation parameters. The basic angle transformation parameters may include single-code location angle increment parameters and area reference offset angle parameters. The single-code location angle increment parameters may include fixed angle values corresponding to each code location, and the area reference offset angle parameters may include the initial offset angle of each area relative to the reference area. Based on the target conversion parameters and the pre-determined angle calculation coefficient, the original calculated value of the bolt rotation angle is calculated, and the angle calculation value of the component to be measured is determined based on the original calculated value of the bolt rotation angle; wherein, the pre-determined angle calculation coefficient can be 0.5.
[0104] In this optional embodiment, the above-mentioned determination of the angular displacement monitoring result of the component under test based on the angle calculation value may include: The calculated angle value is used as the angular displacement monitoring result of the component under test.

[0106] In this optional embodiment, optionally, for example, the target digital signal may include the encoded signal corresponding to the "valid" identifier in the encoded detection result. The core is a 4-bit binary code (0000~1111) and a hexadecimal storage location code (8000~800F, excluding invalid codes 8002 / 8008 / 800A). It is extracted only when the signal validity identifier is "valid". If invalid, it triggers re-acquisition. The target position identifier may include a unique identifier that represents the precise position of the component under test on the angle detection disk, which consists of a patch identifier and an encoded position identifier.
[0107] As can be seen, implementing this optional embodiment can determine the target digital signal of the component under test based on the encoded detection results, thereby determining the target position identifier corresponding to the component under test. Based on the target position identifier, it determines the matching target conversion parameters, and based on the target conversion parameters and the pre-determined angle calculation coefficients, it determines the angle calculation value of the component under test, thus obtaining the angular displacement monitoring result of the component under test. It can extract the effective target digital signal through the encoded detection results, and further derive the two-dimensional target position identifier of the area and the encoded position, realizing the unique and accurate positioning of the bolt on the angle detection plate. This is beneficial to improving the accuracy and reliability of positioning, and also beneficial to improving the positioning precision. Each step of the derivation is based on quantitative data and fixed rules, without subjective judgment, avoiding the results caused by human intervention or scene differences. The fluctuation of the result further improves the accuracy and reliability of positioning. The calculation rules of the target position mark support multi-round area cycling of the angle disk. The angle calculation value is compensated for coaxiality deviation by mechanical installation correction coefficient, which can adapt to multi-round cycling and complex installation scenarios, which is conducive to improving versatility and practicality. The angular displacement monitoring result not only includes the final loosening angle, but also outputs the angle accuracy level and result confidence level at the same time, which intuitively reflects the reliability of the calculation result, greatly improves the efficiency and accuracy of operation and maintenance, further improves the accuracy and reliability of angle calculation, and further enables intelligent measurement and calculation of bolts or nuts based on the angle disk, which is conducive to improving the intelligence and efficiency of measuring the loosening angle of bolts or nuts, as well as improving the accuracy and reliability of measuring the loosening angle of bolts or nuts.

By pre-screening and eliminating abnormal parameters, the error propagation path is cut off at the source, making subsequent encoding matching and angle calculation based on target detection data more accurate. This improves the accuracy and reliability of the screened target detection data, as well as the intelligence and efficiency of the screened target detection data. Furthermore, it enhances the intelligence and efficiency of measuring bolt loosening angles, improving the accuracy and reliability of angle calculations.

It establishes an independent angle association system for each bolt specification through a differentiated angle parameter mapping table. The corresponding mapping relationship can be quickly retrieved using the specification identifier in the component attribute information. This improves the accuracy and reliability of filtering target detection data, enhances the intelligence and efficiency of obtaining target detection data, further improves the accuracy and reliability of angle calculation, and enables intelligent measurement and calculation of bolts or nuts based on the angle disc. This also improves the intelligence and efficiency of measuring the loosening angle of bolts or nuts, as well as the accuracy and reliability of measuring the loosening angle of bolts or nuts.

The generation module 308 is also used to generate fracture warning parameters that match the bolt fracture state.
[0117] It is evident that implementation Figure 4The described device can determine whether fracture state data exists in all target detection data. If it does, it performs data verification on all fracture state data to obtain data verification results and determines whether the data verification results meet the preset fracture judgment conditions. If they do, it determines that the component under test is in a bolt fracture state and generates corresponding fracture warning parameters. This device can accurately determine the fracture state and avoid false alarms and missed alarms. It can also improve the accuracy and reliability of the judgment through multi-dimensional data verification methods, and further improve the accuracy and reliability of data verification based on the comprehensiveness of the data verification dimensions.

Based on the target position identifier, it determines the matching target conversion parameters, and based on the target conversion parameters and pre-determined angle calculation coefficients, it determines the angle calculation value of the component under test, thus obtaining the angular displacement monitoring result of the component under test. It can extract the effective target digital signal from the encoded detection result, and further derive the two-dimensional target position identifier of the area and the encoded position, achieving unique and accurate positioning of the bolt on the angle detection plate. This is beneficial to improving the accuracy and reliability of positioning, as well as improving positioning precision. Each step of the derivation is based on quantitative data and fixed rules, without subjective judgment, avoiding result fluctuations caused by human intervention or scene differences. This further enhances the accuracy and reliability of positioning. The calculation rules for target location identification support multi-cycle rotation of the angle disk. The angle calculation value compensates for coaxiality deviation through mechanical installation correction coefficients, which can adapt to multi-cycle rotation and complex installation scenarios, thus improving versatility and practicality. The angular displacement monitoring results not only include the final loosening angle but also simultaneously output the angle accuracy level and result confidence level, intuitively reflecting the reliability of the calculation results and significantly improving operation and maintenance efficiency and accuracy.
