TECHNICAL FIELD

[0001] The application relates to the technical field of magnesium oxide pipe detection, in particular to a magnesium oxide pipe integrated automatic detection system and method based on data fusion. BACKGROUND

[0002] The magnesium oxide pipe has excellent high-temperature resistance, such as being able to withstand a high temperature of 1500 DEG C or above, and has insulation and chemical stability, and thus becomes a core basic component in key fields such as a metallurgical industry oxygen probe, an electronic industry vacuum device, a high-voltage equipment in the power industry, and the like; the quality of the magnesium oxide pipe directly determines the operation stability, service life and safety reliability of downstream products, for example, in high-voltage power equipment, insufficient pressure resistance of the magnesium oxide pipe may cause insulation breakdown and induce safety accidents; with the continuous improvement of the requirements of the downstream industry on product precision and reliability, the market puts forward higher standards for the quality detection of the magnesium oxide pipe, not only requiring comprehensive coverage of key indicators such as purity, load softening temperature, pressure strength and thermal shock stability, but also putting forward strict requirements on detection precision, efficiency and consistency; at present, the quality detection of the magnesium oxide pipe is mainly in the traditional multi-station step-by-step detection mode, that is, the pipe to be detected is transferred to the purity detection station, the load softening temperature detection station, the pressure strength detection station and the thermal shock stability detection station in sequence by manual or automatic conveying mechanism, and the detection of each single indicator is completed respectively; the step-by-step magnesium oxide pipe detection method has insufficient accuracy and low efficiency; and there are still some defects in the current multi-parameter fusion quality detection of the magnesium oxide pipe, for example, the ordinary data fusion method in the current quality detection of the magnesium oxide pipe adopts a single fusion logic, does not combine with specific detection conditions, and does not consider the coupling relationship between different parameters, resulting in the problem of inaccurate quality detection result of data fusion, and it is difficult to realize accurate quality detection through multi-dimensional feature association. SUMMARY

[0003] The purpose of the present application is to provide a magnesium oxide pipe integrated automatic detection system and method based on data fusion to solve the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a magnesium oxide pipe integrated automatic detection method based on data fusion, the method comprising the following steps: S1, collecting quality parameters of the magnesium oxide pipe, and setting a comprehensive quality analysis mechanism, and analyzing whether the comprehensive quality of the magnesium oxide pipe is qualified according to the collected quality parameters; S2, setting a quality parameter weight adjustment mechanism, and adaptively adjusting the weight of the core quality parameter in different quality detection scenes according to the different temperature and pressure intensity of different quality detection scenes; S3, set a coupling influence factor analysis mechanism to analyze the joint influence of the purity and sintering temperature of the magnesium oxide tube on the quality detection result, and adjust the comprehensive quality threshold value according to the coupling influence factor obtained by analysis, and further analyze whether the comprehensive quality of the magnesium oxide tube is qualified; S4, store the comprehensive quality analysis result of the magnesium oxide tube, and store the corresponding comprehensive quality detection scene and quality parameter weight adjustment value.

[0005] Further, in step S1: the comprehensive quality analysis mechanism fuses the collected quality parameters of the magnesium oxide tube by setting different and adjustable parameter weights to obtain the comprehensive quality of the magnesium oxide tube, and sets the comprehensive quality threshold values W1 and W2 to preliminarily detect whether the comprehensive quality of the magnesium oxide tube is qualified.

[0006] Further, the thermal shock stability r1, the load softening temperature r2, the component purity r3, the compressive strength r4 and the sintering temperature r5 of the magnesium oxide tube in the quality detection process are collected; the collected quality parameters of the magnesium oxide tube are weighted and fused to obtain the comprehensive quality qualification degree, and the comprehensive quality qualification degree is calculated according to the following formula: ; Wherein, W represents the comprehensive quality qualification degree of the magnesium oxide tube; represents the i-th magnesium oxide tube quality parameter, i represents the magnesium oxide tube quality parameter number, i=1, 2, 3, 4, 5; represents the weight of the magnesium oxide tube quality parameter numbered i in the comprehensive quality qualification degree; represents the qualification threshold value of the magnesium oxide tube quality parameter numbered i; the initial value of the weight is set to ; Set the comprehensive quality qualification threshold values W1 and W2 of the magnesium oxide tube, compare and analyze the obtained comprehensive quality qualification degree with the set threshold values, and judge whether the quality of the magnesium oxide tube to be detected is qualified: If , it indicates that the comprehensive quality qualification degree meets the standard, and it is judged that the quality detection result of the magnesium oxide tube is qualified; If , it indicates that the comprehensive quality qualification degree is low, and it is judged that the preliminary quality detection result of the magnesium oxide tube is pending; If , it indicates that the comprehensive quality qualification degree is abnormally low, and it is judged that the quality detection result of the magnesium oxide tube is unqualified, then the magnesium oxide tube is diverted to the unqualified period storage area.

[0007] Furthermore, in step S2, the automatic quality parameter adjustment mechanism is used to adaptively adjust the weights of quality parameters in the comprehensive quality analysis according to different quality testing scenarios. The weights of the core quality parameters of different testing station scenarios are adjusted according to the temperature and pressure intensity of the testing scenario. Then, the comprehensive quality of the magnesium oxide tube matched with the quality testing scenario is analyzed using the adjusted quality parameter weights.

[0008] Furthermore, in the comprehensive quality inspection process of magnesium oxide pipes, different quality inspection conditions are distinguished, dividing the inspection conditions of magnesium oxide pipes into two types: high-temperature resistance inspection scenario and metallurgical load-bearing inspection scenario. The characteristic parameters of each inspection scenario are scenario temperature and pressure intensity. The temperature threshold for entering the high-temperature scenario is set to T0, and the actual temperature value during the comprehensive quality inspection is T. The pressure intensity threshold for entering the high-pressure scenario is set to P0, and the actual pressure intensity is P. The weight adjustment unit is set to [value missing]. The weights of quality parameters are adaptively adjusted for different detection scenarios; When conducting high-temperature resistance testing, the core quality parameters are thermal shock stability and load softening temperature; therefore, the weight of thermal shock stability in the high-temperature resistance testing scenario is adjusted as follows: Adjust the load softening temperature weighting as follows: And adjust the weights of the remaining parameters as follows: ; When conducting metallurgical load-bearing tests, the core quality parameters are compressive strength and thermal shock stability; therefore, the weight of compressive strength is adjusted as follows: The thermal shock stability weights are adjusted as follows: And adjust the weights of the remaining parameters as follows: Based on different quality inspection scenarios, the weighted analysis of adjusted quality parameters is used to conduct comprehensive quality analysis.

[0009] Furthermore, in step S3: the coupling influence factor analysis mechanism uses the purity and sintering temperature of the magnesium oxide tube to obtain the coupling influence factor, and analyzes the coupling influence factor. If the coupling influence factor is greater than 1, the comprehensive quality threshold W1 is adjusted using the coupling influence factor, and a second comprehensive quality test is performed on the magnesium oxide tubes whose comprehensive quality test results are pending. If the coupling influence factor is less than or equal to 1, the comprehensive quality threshold W1 is not adjusted, and the purity of all magnesium oxide tubes is analyzed separately to re-determine whether the quality of the magnesium oxide tubes is qualified.

[0010] Furthermore, during the quality inspection process, the combined effects of purity and sintering temperature must be considered when setting the comprehensive quality threshold. The coupling influence factor is calculated using the following formula: ; in, represents the coupling effect factor; e represents the natural constant, e=2.718; Analyze the obtained coupling factors, if Then the overall quality threshold W1 is adjusted, and the adjusted threshold is: For magnesium oxide tubes whose initial quality inspection result was pending, a second quality inspection was conducted. Before the second quality inspection, the purity of the magnesium oxide tubes was first analyzed. Then, magnesium oxide tubes whose initial quality inspection result was pending will be directly marked as qualified; if Then, the adjusted threshold is used to perform a second quality check on the magnesium oxide tube. The results of the second check are as follows: If If so, the magnesium oxide tube is judged to be of acceptable quality; if If so, the magnesium oxide tube is judged to be of substandard quality; like If so, the overall quality threshold W1 will not be adjusted; and a separate test for the purity of all magnesium oxide tubes will be added, with the test results as follows: If If the purity of the magnesium oxide tube is within the minimum threshold range, the initial quality test result remains unchanged, but magnesium oxide tubes marked as having undetermined quality in the initial quality test are directly marked as unqualified. If the result is negative, it indicates that the purity of the magnesium oxide tube is abnormally low. Therefore, the initial test result, which was deemed acceptable, should be modified, and the magnesium oxide tube should be marked as unacceptable.

[0011] Furthermore, in step S4: the comprehensive quality analysis results of the magnesium oxide tubes are stored, along with the corresponding comprehensive quality inspection scenarios and quality parameter weight adjustment values. For magnesium oxide tubes marked as unqualified, an analysis of the reasons for non-compliance is conducted. Based on the stored data, the specific abnormal quality parameters can be traced through adjustments to the comprehensive quality inspection scenarios, quality parameter weights, and comprehensive quality parameter thresholds.

[0012] The integrated automatic inspection system for magnesium oxide tubes based on data fusion includes a magnesium oxide tube data acquisition module, a magnesium oxide tube comprehensive quality analysis module, a quality parameter weight adjustment module, a coupling influence factor analysis module, and a detection data storage module. The magnesium oxide tube data acquisition module is used to collect magnesium oxide tube quality parameters including thermal shock stability, load softening temperature, composition purity, compressive strength, and sintering temperature. The magnesium oxide tube comprehensive quality analysis module is used to analyze whether the comprehensive quality of the magnesium oxide tube is qualified based on the collected quality parameters; The quality parameter weight adjustment module is used to adaptively adjust the weights of core quality parameters in different quality testing scenarios based on the different temperatures and pressure intensities of different quality testing scenarios. The coupled influence factor analysis module is used to analyze the combined influence of the purity and sintering temperature of magnesium oxide tubes on the quality test results, adjust the comprehensive quality threshold according to the coupled influence factors obtained from the analysis, and further analyze whether the comprehensive quality of magnesium oxide tubes is qualified. The detection data storage module is used to store the comprehensive quality analysis results of magnesium oxide tubes, and to store the corresponding comprehensive quality detection scenarios and quality parameter weight adjustment values.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention improves the efficiency of magnesium oxide tube quality inspection by jointly analyzing different quality parameters of magnesium oxide tubes through a comprehensive quality analysis mechanism. Furthermore, the comprehensive quality analysis process incorporates a quality parameter weight adjustment mechanism based on different magnesium oxide tube quality inspection scenarios. This mechanism adaptively adjusts the weights of quality parameters according to changes in the inspection scenario, thereby improving the matching degree between the comprehensive quality inspection results and the inspection scenario, and enhancing the accuracy of the quality inspection results. Simultaneously, this invention considers the combined influence of magnesium oxide tube material purity and sintering temperature on the quality inspection results. A coupled influence factor analysis mechanism is established, utilizing the influence of coupled influence factors on the comprehensive quality threshold to adjust the comprehensive quality threshold. The adjusted comprehensive quality threshold is then used to perform a secondary inspection of the comprehensive quality of the magnesium oxide tubes, reducing the misjudgment rate of the comprehensive quality inspection.

Set up a quality parameter weight adjustment mechanism to adaptively adjust the weights of core quality parameters in different quality testing scenarios based on the different temperatures and pressure intensities of different quality testing scenarios. S3.

S4. Store the comprehensive quality analysis results of the magnesium oxide tube, and store the corresponding comprehensive quality inspection scenario and quality parameter weight adjustment values.

[0017] In step S1: The comprehensive quality analysis mechanism integrates the quality parameters of the collected magnesium oxide tubes by setting different and adjustable parameter weights to obtain the comprehensive quality of the magnesium oxide tubes, and sets comprehensive quality thresholds W1 and W2 to conduct an initial test on whether the comprehensive quality of the magnesium oxide tubes is qualified.

[0018] The thermal shock stability (r1), load softening temperature (r2), composition purity (r3), compressive strength (r4), and sintering temperature (r5) of magnesium oxide tubes were collected during the quality inspection process. These quality parameters were then weighted and fused to obtain the overall quality pass rate, which was calculated using the following formula: ; Where W represents the overall quality qualification rate of the magnesium oxide tube; This represents the quality parameter of the i-th magnesium oxide tube, where i represents the magnesium oxide tube quality parameter number, i=1, 2, 3, 4, 5; This indicates the weight of the quality parameter of the magnesium oxide tube numbered i in the overall quality compliance. This represents the acceptable threshold for the quality parameters of the magnesium oxide tube numbered i. Set comprehensive quality pass thresholds W1 and W2 for magnesium oxide tubes, compare and analyze the obtained comprehensive quality pass rates with the set thresholds to determine whether the quality of the magnesium oxide tube under test is qualified. like If the overall quality meets the standard, the quality test result of the magnesium oxide tube is deemed qualified. like If the overall quality pass rate is low, the initial quality test result of the magnesium oxide tube is to be determined. like If the overall quality pass rate is abnormally low, the magnesium oxide tube is judged to be unqualified in the quality test, and the magnesium oxide tube will be diverted to the unqualified storage area.

[0019] In step S2, the automatic quality parameter adjustment mechanism is used to adaptively adjust the weights of quality parameters in the comprehensive quality analysis according to different quality testing scenarios. The parameter weights of the core quality parameters of different testing station scenarios are adjusted according to the temperature and pressure intensity of the testing scenario. Then, the adjusted quality parameter weights are used to analyze the comprehensive quality of magnesium oxide tubes that match the quality testing scenario.

[0020] In the comprehensive quality inspection of magnesium oxide pipes, different quality inspection conditions are distinguished, dividing the inspection conditions into two types: high-temperature resistance inspection scenario and metallurgical load-bearing inspection scenario. The characteristic parameters of each inspection scenario are scenario temperature and pressure intensity. The temperature threshold for entering the high-temperature scenario is set to T0, and the actual temperature value during the comprehensive quality inspection is T. The pressure intensity threshold for entering the high-pressure scenario is set to P0, and the actual pressure intensity is P. The weight adjustment unit is set to [value missing]. The weights of quality parameters are adaptively adjusted for different detection scenarios; When conducting high-temperature resistance testing, the core quality parameters are thermal shock stability and load softening temperature; therefore, the weight of thermal shock stability in the high-temperature resistance testing scenario is adjusted as follows: Adjust the load softening temperature weighting as follows: And adjust the weights of the remaining parameters as follows: ; When conducting metallurgical load-bearing tests, the core quality parameters are compressive strength and thermal shock stability; therefore, the weight of compressive strength is adjusted as follows: The thermal shock stability weights are adjusted as follows: And adjust the weights of the remaining parameters as follows: Based on different quality inspection scenarios, the weighted analysis of adjusted quality parameters is used to conduct comprehensive quality analysis.

[0021] In step S3: The coupling influence factor analysis mechanism uses the purity and sintering temperature of the magnesium oxide tube to obtain the coupling influence factor, and analyzes the coupling influence factor. If the coupling influence factor is greater than 1, the comprehensive quality threshold W1 is adjusted using the coupling influence factor, and a second comprehensive quality test is performed on the magnesium oxide tubes whose comprehensive quality test results are pending. If the coupling influence factor is less than or equal to 1, the comprehensive quality threshold W1 is not adjusted, and the purity of all magnesium oxide tubes is analyzed separately to re-determine whether the quality of the magnesium oxide tubes is qualified.

[0022] During quality inspection, the combined effects of purity and sintering temperature must be considered when setting the overall quality threshold. The coupling influence factor is calculated using the following formula: ; in, Indicates the coupling effect factor; e represents the natural constant; Analyze the obtained coupling factors, if Then the overall quality threshold W1 is adjusted, and the adjusted threshold is: For magnesium oxide tubes whose initial quality inspection result was pending, a second quality inspection was conducted. Before the second quality inspection, the purity of the magnesium oxide tubes was first analyzed. Then, magnesium oxide tubes whose initial quality inspection result was pending will be directly marked as qualified; if Then, the adjusted threshold is used to perform a second quality check on the magnesium oxide tube. The results of the second check are as follows: If If so, the magnesium oxide tube is judged to be of acceptable quality; if If so, the magnesium oxide tube is judged to be of substandard quality; like If so, the overall quality threshold W1 will not be adjusted; and a separate test for the purity of all magnesium oxide tubes will be added, with the test results as follows: If If the purity of the magnesium oxide tube is within the minimum threshold range, the initial quality test result remains unchanged, but magnesium oxide tubes marked as having undetermined quality in the initial quality test are directly marked as unqualified. If the result is negative, it indicates that the purity of the magnesium oxide tube is abnormally low. Therefore, the initial test result, which was deemed acceptable, should be modified, and the magnesium oxide tube should be marked as unacceptable.

[0023] In step S4: The comprehensive quality analysis results of the magnesium oxide tubes are stored, along with the corresponding comprehensive quality inspection scenarios and quality parameter weight adjustment values. For magnesium oxide tubes marked as unqualified, an analysis of the reasons for non-compliance is performed. Based on the stored data, the specific abnormal quality parameters can be traced through adjustments to the comprehensive quality inspection scenarios, quality parameter weights, and comprehensive quality parameter thresholds.

The coupled influence factor analysis module is used to analyze the combined influence of the purity and sintering temperature of magnesium oxide tubes on the quality test results, and adjust the comprehensive quality threshold according to the coupled influence factors obtained from the analysis, and further analyze whether the comprehensive quality of magnesium oxide tubes is qualified. The detection data storage module is used to store the comprehensive quality analysis results of magnesium oxide tubes, as well as the corresponding comprehensive quality detection scenarios and quality parameter weight adjustment values.

[0025] Example 1: In step S1: The following parameters were collected during the quality inspection of the magnesium oxide tube: thermal shock stability (r1=5), load softening temperature (r2=1500℃), composition purity (r3=0.99), compressive strength (r4=80MPa), and sintering temperature (r5=1600℃). The collected quality parameters of the magnesium oxide tube were weighted and fused to obtain the comprehensive quality pass rate. The comprehensive quality pass rate was calculated according to the following formula: ; Where W represents the overall quality qualification rate of the magnesium oxide tube; This represents the quality parameter of the i-th magnesium oxide tube, where i represents the magnesium oxide tube quality parameter number, i=1, 2, 3, 4, 5; This indicates the weight of the quality parameter of the magnesium oxide tube numbered i in the overall quality compliance. This represents the acceptable threshold for the quality parameters of the magnesium oxide tube numbered i. ; ; ; ; The initial weight values ​​are set to... ; Set the overall quality pass rate thresholds W1=1 and W2=0.95 for magnesium oxide tubes. Compare and analyze the obtained overall quality pass rate with the set thresholds to determine whether the quality of the magnesium oxide tube to be tested is qualified. like If the overall quality meets the standard, the quality test result of the magnesium oxide tube is deemed qualified. like If the overall quality pass rate is low, the initial quality test result of the magnesium oxide tube is to be determined. like If the overall quality pass rate is abnormally low, the magnesium oxide tube is judged to be unqualified in the quality test, and the magnesium oxide tube will be diverted to the unqualified storage area.

[0026] In step S2: During the comprehensive quality inspection of magnesium oxide pipes, different quality inspection conditions are distinguished, and the inspection conditions of magnesium oxide pipes are divided into two types: high-temperature resistance inspection scenario and metallurgical load-bearing inspection scenario; the characteristic parameters of the inspection scenario are scenario temperature and pressure intensity. The temperature threshold for entering the high-temperature scenario is set to T0=800℃, and the actual temperature value during the comprehensive quality inspection is T=1200℃. The pressure intensity threshold for entering the high-pressure scenario is set to P0=60MPa, and the actual pressure intensity is P=80MPa; the weight adjustment unit value is set to... The weights of quality parameters are adaptively adjusted for different detection scenarios; When conducting high-temperature resistance testing, the core quality parameters are thermal shock stability and load softening temperature; therefore, the weight of thermal shock stability in the high-temperature resistance testing scenario is adjusted as follows: Adjust the load softening temperature weighting as follows: And adjust the weights of the remaining parameters as follows: ; ; ; If W=1.001, then the overall quality of the magnesium oxide tube is qualified in the high-temperature resistance test. When conducting metallurgical load-bearing tests, the core quality parameters are compressive strength and thermal shock stability; therefore, the weight of compressive strength is adjusted as follows: The thermal shock stability weights are adjusted as follows: And adjust the weights of the remaining parameters as follows: Based on different quality inspection scenarios, a comprehensive quality analysis is conducted using the adjusted quality parameter weights. ; ; If W=0.999, then the overall quality of the magnesium oxide pipe in the metallurgical load-bearing test is to be determined.

[0027] In step S3: The coupling influence factor analysis mechanism uses the purity and sintering temperature of the magnesium oxide tube to obtain the coupling influence factor, and analyzes the coupling influence factor. If the coupling influence factor is greater than 1, the comprehensive quality threshold W1=0.98 is adjusted using the coupling influence factor, and a second comprehensive quality test is performed on the magnesium oxide tubes whose comprehensive quality test results are pending. If the coupling influence factor is less than or equal to 1, the comprehensive quality threshold W1 is not adjusted, and the purity of all magnesium oxide tubes is analyzed separately to re-determine whether the quality of the magnesium oxide tubes is qualified.

[0028] During quality inspection, the combined effects of purity and sintering temperature must be considered when setting the overall quality threshold. The coupling influence factor is calculated using the following formula: ; in, Indicates the coupling effect factor; e represents the natural constant; ; Analyzing the obtained coupling factors, then... Then the overall quality threshold W1 is adjusted, and the adjusted threshold is: ; For magnesium oxide tubes whose initial quality inspection result was pending, a second quality inspection was conducted. Before the second quality inspection, the purity of the magnesium oxide tubes was first analyzed. Then, magnesium oxide tubes whose initial quality inspection result was pending will be directly marked as qualified; if The adjusted threshold is then used to perform a secondary quality check on the magnesium oxide tube. ;but The magnesium oxide tube was judged to be of acceptable quality.
