[0025] The embodiments of the present application solve the problem of unstable glass fiber quality in the prior art by providing a glass fiber production process processing method and system based on machine learning, thereby achieving precise control of glass fiber quality.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figure 1 As shown, it is a flow chart of a glass fiber production process processing method based on machine learning provided in an embodiment of the present application. The method is applied to a glass fiber production process processing system based on machine learning, and the method includes the following steps: when the drawing device receives a drawing signal, it starts to execute glass fiber drawing production processing, synchronously collects glass fiber drawing effect parameters, and analyzes to obtain glass fiber drawing effect indicators; based on the glass fiber drawing effect indicators, it is analyzed to determine whether to execute drawing cooling processing. If the drawing cooling processing is executed, a cooling signal is sent to the cooling device; if the drawing cooling processing is not executed, the drawing device is adjusted; when the cooling device receives a cooling signal, it obtains the aging parameters of the cooling execution device, and analyzes to obtain the aging index of the cooling device, thereby matching to obtain the aging correction coefficient, synchronously obtains the cooling space environment impact parameters, and analyzes to obtain the cooling space environment impact index, thereby matching to obtain the temperature correction factor; based on the aging correction coefficient and the temperature correction factor, the cooling parameters of the cooling device are preliminarily corrected to obtain the corrected cooling device adjustment parameters, and the glass fiber cooling processing is performed based on the corrected cooling device adjustment parameters.

[0028] In this embodiment, when the drawing equipment receives the drawing signal, it starts to execute the glass fiber drawing production process, synchronously collects the glass fiber drawing effect parameters, and analyzes to obtain the glass fiber drawing effect index, thereby realizing real-time monitoring and control of the glass fiber drawing process; by judging whether to execute the drawing cooling process based on the glass fiber drawing effect index, and sending a cooling signal or adjusting the drawing equipment, the coordination of the drawing and cooling processes is optimized; by obtaining the aging parameters of the cooling execution equipment and the cooling space environmental influencing parameters, the aging correction coefficient and the temperature correction factor are matched, and the glass fiber is cooled based on the corrected cooling equipment adjustment parameters, thereby realizing intelligent control and precise adjustment of the glass fiber drawing and cooling processes, effectively solving the problem of unstable glass fiber quality in the prior art.

[0029] Furthermore, glass fiber drawing effect parameters are collected and analyzed to obtain glass fiber drawing effect indicators, specifically including: randomly arranging sampling points for each glass fiber, using a camera to monitor the glass fiber drawing process in real time, and collecting glass fiber drawing effect parameters, including the number of cracks in each glass fiber and the color, refractive index and temperature of each glass fiber sampling point; obtaining a preset drawing effect standard set in a database, and analyzing it with the glass fiber drawing effect parameters to obtain a glass fiber drawing effect indicator; the drawing effect standard set includes standard values for the number of cracks, standard values for color, standard values for refractive index and standard values for temperature; the glass fiber drawing effect indicator is used to characterize the production effect of glass fiber drawing.

[0030] In this embodiment, the color of the glass fiber sampling point refers to the color quantified using the RGB color model, specifically the R value. It should be noted that the glass fiber drawing effect parameters are obtained by taking pictures or videos with a camera and then identifying the taken pictures or videos. For example, the number of cracks can be obtained by taking pictures of the glass fiber with a camera and statistically analyzing the pictures using image processing software (such as Photoshop). The refractive index can be obtained by measuring with a refractometer, and the temperature can be obtained by using thermal imaging technology, where the temperature refers to the surface temperature of the glass fiber during the drawing process, and the temperature can also be obtained by a temperature sensor.

[0031] The fiberglass drawing effect index is derived by analyzing the fiberglass drawing effect parameters, taking into account the interplay between these parameters. For example, excessively high temperatures can cause structural instability in the fiberglass, leading to cracks. The appearance of cracks, in turn, affects the fiberglass's refractive index. Color changes are caused by temperature fluctuations and unstable drawing speeds. Excessively high temperatures can cause the fiberglass's color to deviate from the standard value, resulting in uneven color differences. High temperatures can also cause changes in the fiberglass's refractive index.

[0032] The fewer cracks, the more complete the glass fiber structure and the better the drawing effect. The closer the refractive index is to the standard refractive index value, the more stable the glass fiber, the better the glass fiber quality and the greater the drawing effect index. The closer the temperature at the glass fiber sampling point is to the standard temperature value, the more stable the temperature is and the more stable the quality of the resulting glass fiber.

[0033] The specific method to obtain the glass fiber drawing effect index is as follows:

[0034]

[0035] It should be noted that XG represents the glass fiber drawing effect index, e represents the natural constant, and XZ i Indicates the number of cracks in the i-th glass fiber, i represents the number of the glass fiber, i=1,2,...,i max ,i max Indicates the total number of glass fibers, ΔXZ indicates the standard value of crack number, XD j Indicates the color of the jth glass fiber sampling point, j represents the number of the sampling point, j=1,2,...,j max ,j max Indicates the total number of sampling points, ΔXD indicates the color standard value, XQ j represents the refractive index of the jth glass fiber sampling point, ΔXQ represents the standard value of the refractive index, and XC j represents the temperature of the j-th glass fiber sampling point, and ΔXC represents the temperature standard value.

[0036] By acquiring the operating parameters of the drawing equipment and simultaneously collecting the glass fiber drawing effect parameters, it is possible to monitor the changes in various key indicators during the drawing process in real time, thereby achieving dynamic tracking and precise analysis of the drawing process, thereby improving the drawing quality and production efficiency of the glass fiber. By evaluating the relationship between the glass fiber drawing effect parameters and the standard values, it is possible to promptly detect deviations between the drawing parameters and the standard values, and through analysis, obtain the drawing effect indicators, thereby optimizing the operating parameters of the drawing equipment and making the drawing process more in line with process requirements. By synchronizing the operating parameters of the drawing equipment and the glass fiber drawing effect parameters, real-time monitoring and precise analysis of the drawing process are achieved; thereby optimizing the matching of process parameters with standard values, improving the process accuracy and product quality consistency of the glass fiber drawing process, and achieving the goal of enhancing process stability and improving production efficiency.

[0037] Furthermore, based on the glass fiber drawing effect index, analysis is performed to determine whether to perform drawing cooling treatment. The specific steps include: obtaining the glass fiber drawing effect threshold preset in the database, and comparing it with the glass fiber drawing effect index. If the glass fiber drawing effect index is above the glass fiber drawing effect threshold, the drawing cooling treatment is performed. If the glass fiber drawing effect index is less than the glass fiber drawing effect threshold, the drawing cooling treatment is not performed.

[0038] In this embodiment, by determining whether the glass fiber drawing effect index meets the threshold requirements, the drawing cooling process is performed only when necessary, avoiding the need for cooling treatment even though the drawing process is unqualified, avoiding excessive use of cooling equipment, thereby reducing energy consumption and improving the efficiency of cooling resource utilization. By dynamically adjusting the cooling process based on the glass fiber drawing effect index, the processing steps can be optimized according to the actual situation during the drawing process, ensuring the necessity and appropriateness of the cooling process, thereby effectively improving the quality stability and consistency of the glass fiber products. By reducing unnecessary cooling processes, the operating frequency and workload of the cooling equipment are reduced, thereby effectively extending the service life of the equipment.

[0039] Furthermore, when the cooling device receives the cooling signal, the cooling execution device aging parameters are obtained, and the cooling device aging index is obtained by analysis. The specific steps include: when the cooling device receives the cooling signal, the cooling execution device aging parameters are obtained, and the cooling execution device aging parameters include: the maximum coolant flow rate, the maximum coolant flow rate, the maximum vibration amplitude of the cooling device and the maximum coolant temperature deviation within the preset inspection period; the cooling execution device reference set preset in the database is obtained, and the cooling execution device aging parameters are analyzed to obtain the cooling device aging index; the cooling execution device reference set includes the historical maximum coolant flow rate, the historical maximum coolant flow rate, the cooling device vibration amplitude reference value and the coolant temperature deviation allowable value; the cooling device aging index is used to characterize the aging degree of the cooling device.

[0040] In this embodiment, the maximum coolant flow rate can be measured using an ultrasonic flowmeter or laser Doppler velocimeter installed in the cooling pipeline, or can be measured using a tachometer. The maximum coolant flow rate can be measured using a volumetric flow meter. The maximum vibration amplitude of the cooling device can be obtained by using a vibration sensor to record the maximum vibration amplitude of the cooling device in real time during operation. The coolant temperature deviation can be measured and statistically obtained using a temperature sensor.

[0041] The cooling equipment aging index is derived by analyzing cooling equipment aging parameters (maximum coolant flow rate, maximum coolant flow rate, maximum cooling equipment vibration amplitude, and coolant temperature deviation). This takes into account the interplay between these parameters. For example, a slower maximum coolant flow rate results in slower cooling, which reduces the overall cooling efficiency of the cooling equipment. Slower coolant flow rate and coolant flow rate indicate more severe cooling equipment aging, resulting in greater cooling equipment instability and, consequently, increased cooling equipment vibration amplitude. Greater coolant temperature deviation indicates more unstable cooling equipment operation, indicating more severe cooling equipment aging.

[0042] The aging index of the cooling equipment is obtained by:

[0043]

[0044] Where LH represents the cooling equipment aging index, FG represents the maximum coolant flow rate, ΔFG represents the historical maximum coolant flow rate, FD represents the maximum coolant flow rate, ΔFD represents the historical maximum coolant flow rate, Fσ represents the maximum vibration amplitude of the cooling equipment, ΔFσ represents the reference value of the cooling equipment vibration amplitude, FL represents the maximum coolant temperature deviation, ΔFL represents the allowable coolant temperature deviation, and e represents a natural constant.

[0045] After the cooling device receives the cooling signal, the aging parameters of the cooling execution device are obtained and the cooling device aging index is analyzed to evaluate the operating status and aging degree of the cooling device, thereby providing an accurate correction basis for subsequent cooling operations. At the same time, by introducing the analysis of multiple parameters such as the cooling pipe pollutant coverage rate, the cooling equipment refrigeration efficiency, and the maximum flow rate of the coolant, the performance status of the equipment can be reflected in multiple dimensions, effectively improving the accuracy of the cooling equipment aging index. By comparing the aging parameters of the cooling execution device with the factory parameters, the corresponding aging range and correction coefficient can be quickly matched, thereby achieving precise adjustment of the cooling equipment operating parameters, significantly improving the operating efficiency and service life of the cooling equipment, and providing reliable protection for the glass fiber production process.

[0046] Furthermore, an aging correction coefficient is obtained by this matching, and the specific steps include: obtaining the aging index intervals of each cooling device preset in the database and the aging reference correction coefficient corresponding to each cooling device aging index interval, comparing the cooling device aging index with each cooling device aging index interval, and if the cooling device aging index is within a certain cooling device aging index interval, obtaining the aging reference correction coefficient corresponding to the cooling device aging index interval as the aging correction coefficient.

[0047] In this embodiment, by comparing the cooling equipment aging index with the cooling equipment aging index intervals preset in the database, the corresponding aging reference correction coefficient is accurately matched, thereby providing customized correction parameters for different degrees of equipment aging. This improves the pertinence and accuracy of cooling parameter adjustments, avoiding the degradation of cooling performance caused by manual judgment errors or inaccurate corrections. In addition, by introducing a matching mechanism between aging intervals and corresponding correction coefficients, the complex parameter calculation process is simplified, the response efficiency is improved, and the service life of the cooling equipment is extended.

[0048] Furthermore, the cooling space environmental impact index is obtained, and the temperature correction factor is obtained by matching it. The specific steps include: obtaining the volume of the cooling space, matching the volume of the cooling space with each cooling volume interval in the database, obtaining the number of cooling point layouts in the cooling space, and arranging the cooling points to obtain the air flow rate, ambient temperature and ambient humidity of each cooling layout point; obtaining the cooling space reference impact set preset in the database, and analyzing it with the cooling space environmental impact parameters to obtain the cooling space environmental impact index; the cooling space reference impact set includes an air flow rate reference value, an ambient temperature reference value and an ambient humidity reference value; the cooling space environmental impact index is used to characterize the degree of influence of the environmental factors of the cooling space on the cooling effect of the cooling equipment; obtaining each cooling space environmental impact index interval preset in the database and the temperature reference correction factor corresponding to each cooling space environmental impact index interval, and comparing them with the cooling space environmental impact index. If the cooling space environmental impact index is within a certain cooling space environmental impact index interval, then obtaining the temperature reference correction factor corresponding to the cooling space environmental impact index interval as the temperature correction factor.

[0049] In this embodiment, the air velocity in the cooling area can be measured using a hot-wire anemometer, an ultrasonic anemometer, or an airflow meter. The ambient temperature in the cooling space can be measured using an infrared thermometer or a temperature and humidity sensor. The ambient humidity in the cooling space can be obtained by obtaining real-time humidity data from the temperature and humidity sensor.

[0050] Furthermore, the cooling space environmental impact index is obtained, and the specific method is as follows:

[0051]

[0052] Where, LK represents the cooling space environmental impact index, LS k Indicates the air flow rate of the kth cooling layout point, k represents the number of the cooling layout point, k = 1, 2, 3, ..., k max , k maxIndicates the total number of cooling arrangement points, ΔLS indicates the reference value of air flow rate in the cooling area, LH k represents the ambient temperature of the kth cooling layout point, ΔLH represents the ambient temperature reference value, and LD k represents the ambient humidity of the kth cooling layout point, and ΔLD represents the ambient humidity reference value.

[0053] In this embodiment, the cooling space environmental impact index is obtained by analyzing the cooling space environmental impact parameters (air flow rate, ambient temperature and ambient humidity of each cooling layout point), taking into account the mutual influence relationship between these parameters. For example, the air flow rate will affect the heat diffusion efficiency of each cooling layout point, and at the same time affect the temperature distribution of the cooling space. The ambient temperature of the cooling space directly determines the cooling efficiency, while the ambient humidity indirectly affects the cooling process by affecting the thermal conductivity and evaporation rate of the air. When the ambient temperature is high, the amount of heat that the cooling device needs to dissipate increases, resulting in increased cooling difficulty. The higher the ambient humidity, the greater the water vapor content in the air, which is less conducive to heat loss. Therefore, the higher the ambient temperature and the greater the ambient humidity, the slower the heat exchange in the environment, which affects the cooling efficiency.

[0054] By acquiring air velocity, ambient temperature, and humidity parameters at each cooling point within the cooling space and comparing them with reference values in a database, we can generate cooling space environmental impact indicators, thereby quantifying the degree to which environmental factors influence cooling equipment performance. This effectively reduces fluctuations in cooling equipment operation caused by environmental changes and improves cooling performance stability. By monitoring these parameters in real time and matching correction factors, we can achieve dynamic optimization and control of cooling equipment, improve cooling efficiency, simplify the cooling equipment parameter calibration process in complex environments, and reduce errors caused by manual intervention.

[0055] Furthermore, based on the aging correction coefficient and the temperature correction factor, the cooling parameters of the cooling equipment are preliminarily corrected to obtain the corrected cooling equipment adjustment parameters. The specific steps include: obtaining the cooling parameters of the cooling equipment, the cooling parameters of the cooling equipment include cooling water flow rate, cooling water temperature and cooling water pressure; based on the aging correction coefficient, the cooling water flow rate, cooling water pressure and cooling air flow rate of the cooling equipment are preliminarily corrected, and based on the temperature correction factor, the cooling water temperature and cooling air temperature of the cooling equipment are preliminarily corrected to obtain the corrected cooling equipment adjustment parameters; the corrected cooling equipment adjustment parameters include the preliminarily corrected cooling water flow rate, cooling water temperature and cooling water pressure.

[0056] In this embodiment, by making a preliminary correction to the cooling parameters of the cooling equipment based on the aging correction coefficient and the temperature correction factor, it is possible to effectively deal with the performance deviation of the cooling equipment caused by equipment aging and changes in the cooling environment during long-term operation. By making aging corrections to the cooling water flow rate, cooling water pressure and cooling air flow rate, it is possible to accurately compensate for changes in fluid dynamics parameters caused by equipment wear or equipment aging, thereby ensuring the stability of the cooling system. On the other hand, by correcting the cooling water temperature and cooling air temperature using the temperature correction factor, the cooling parameters can be dynamically adjusted to adapt to changes in ambient temperature, avoiding a reduction in cooling efficiency due to environmental factors. The corrected cooling equipment adjustment parameters lay the foundation for subsequent precise control, improve the operational adaptability of the cooling equipment under complex working conditions, thereby optimizing and improving the cooling performance and extending the service life of the equipment.

[0057] Furthermore, it also includes obtaining the actual glass fiber quality indicators after the glass fiber cooling treatment, and analyzing them to obtain the glass fiber quality judgment results, and judging whether to input them as verification set data into the machine learning quality prediction model based on the glass fiber quality judgment results, thereby updating the machine learning quality prediction model.

[0058] In this embodiment, it should be noted that the actual glass fiber quality index after the glass fiber is cooled is obtained and analyzed to obtain the glass fiber quality determination result. The specific steps include: obtaining the glass fiber quality determination threshold preset in the database, and comparing it with the actual glass fiber quality index after the glass fiber is cooled. If the actual glass fiber quality index after the glass fiber is cooled is above the glass fiber quality determination threshold, the glass fiber quality determination result is that the glass fiber quality is qualified; if the actual glass fiber quality index after the glass fiber is cooled is less than the glass fiber quality determination threshold, the glass fiber quality determination result is that the glass fiber quality is unqualified.

[0059] The glass fibers are sampled to obtain glass fiber samples, and the glass fiber samples are tested. The diameter range of the glass fiber refers to measuring the glass fiber sample diameter at both ends, and then calculating the diameter difference. All samples are analyzed, and the maximum diameter difference is marked as the diameter range of the glass fiber. The tensile strength, heat resistance temperature and number of surface cracks of the glass fiber refer to testing all glass fiber samples and then obtaining the average value.

[0060] The actual glass fiber quality index is obtained, and the steps include: obtaining quality parameters of the glass fiber, which include the diameter range, tensile strength, heat resistance temperature and the number of surface cracks of the glass fiber; obtaining a glass fiber benchmark set preset in a database, which includes a diameter range benchmark value, a tensile strength benchmark value, a heat resistance temperature benchmark value and a surface crack number benchmark value; and analyzing the quality parameters of the glass fiber with the glass fiber benchmark set to obtain the actual glass fiber quality index.

[0061] The diameter range of glass fibers can be measured using a laser diameter gauge. The tensile strength can be determined by randomly sampling the glass fibers, placing the sampled glass fiber samples in a tensile testing machine (such as an electronic universal testing machine) and stretching them, then recording the maximum tensile force at fiber breakage. The heat resistance temperature can be measured using a thermal analyzer, and the number of surface cracks can be determined by scanning and identifying them using a scanning electron microscope (SEM).

[0062] The actual glass fiber quality index is obtained by:

[0063]

[0064] Wherein, SZ represents the actual glass fiber quality index, XG represents the glass fiber drawing effect index, JC represents the diameter range of the glass fiber, ΔJC represents the diameter range reference value, SQ represents the tensile strength of the glass fiber, ΔSQ represents the tensile strength reference value, SW represents the heat resistance temperature of the glass fiber, ΔSW represents the heat resistance temperature reference value, SN represents the number of surface cracks of the glass fiber, ΔSN represents the surface crack number reference value, and e represents a natural constant.

[0065] The actual glass fiber quality index is obtained by analyzing the quality parameters of glass fiber (glass fiber diameter range, tensile strength, heat resistance temperature, maximum bending angle, and number of surface cracks). This takes into account the mutual influence between these parameters. For example, the smaller the diameter range, the better the geometric uniformity of the fiber, which can improve the tensile strength and heat resistance temperature, and reduce the formation of surface cracks. Fibers with higher tensile strength generally have better heat resistance. The higher the heat resistance temperature, the more conducive it is to improving the fiber's bending performance in high temperature environments, preventing the increase of cracks and the decrease of tensile properties.

[0066] The calculation formula of the machine learning quality prediction model is:

[0067]

[0068] Where, JQ represents the predicted quality value of glass fiber, XD j Indicates the color of the jth glass fiber sampling point, j represents the number of the sampling point, j=1,2,...,j max ,j max Indicates the total number of sampling points, ΔXD indicates the color standard value, XQ j represents the refractive index of the jth glass fiber sampling point, ΔXQ represents the standard value of the refractive index, and XC j represents the temperature of the j-th glass fiber sampling point, ΔXC represents the temperature standard value, FL represents the maximum deviation of the coolant temperature, ΔFL represents the allowable value of the coolant temperature deviation, and e represents a natural constant.

[0069] It should be noted that the quality prediction value of the glass fiber is obtained by obtaining the color, refractive index, and temperature of the glass fiber sampling point and performing a comprehensive analysis with the coolant temperature. This is to conduct timely monitoring and quality prediction during the glass fiber production process. If the predicted glass fiber quality is unqualified, it can be adjusted in time during the production process to prevent the phenomenon of unqualified product quality due to untimely adjustment, while avoiding waste of resources and improving production efficiency.

According to the analysis of the actual glass fiber quality indicators, the machine learning quality prediction model is adjusted to obtain a more accurate glass fiber quality prediction value, thereby preventing the misjudgment of glass fiber quality prediction due to inaccurate glass fiber prediction values.
