Description

Technical Field

[0001] This invention relates to the field of production line monitoring technology, specifically to a monitoring and management system and method for a polyvinyl chloride fluorite coating production line. Background Technology

[0002] Polyvinyl chloride (PVC) fluorite coatings are widely used in anti-corrosion projects due to their excellent anti-corrosion properties and superior weather resistance. However, at present, the production line of PVC fluorite coatings still faces the following challenges: Because of the lag in quality assessment, if a defective color paste is found in production, it is often not identified until tens of minutes or hours later, resulting in a waste of resources. Adjustments to process parameters rely mainly on experience and lack scientific evaluation models, often making it difficult to accurately pinpoint the main parameters causing quality degradation. The lack of consistency in quality evaluation standards among different batches, different equipment, and different operators leads to subjective quality assessment results and standard drift. The existing system decouples evaluation and feedback, making it impossible to automatically calculate adjustment paths or perform automatic corrective actions when quality fails to meet standards. Summary of the Invention

[0003] In view of the above-mentioned problems, the present invention is proposed.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for monitoring and managing a polyvinyl chloride fluorite coating production line, characterized by comprising the following steps: Real-time collection of production line operation data, and dynamic evaluation of pigment dispersion quality based on the collected operation data, specifically: The process involves collecting real-time production line operation data and constructing a pigment dispersion quality assessment model. The collected real-time operation data serves as the model's input, and the model's output is used to dynamically assess pigment quality. This also includes... The dynamic evaluation of pigment dispersion quality is carried out through a two-layer evaluation mechanism, including real-time operation parameter verification based on the constructed safety production comparison dataset of PVC fluorite coating production line, and dynamic evaluation of pigment dispersion quality by constructing a pigment dispersion quality evaluation model. Furthermore, based on the evaluation results of pigment dispersion quality, feedback adjustments are made to the production of polyvinyl chloride fluorite coatings, specifically: Based on the results of the pigment dispersion quality assessment, the weight coefficients of the parameters are dynamically adjusted, and the pigment quality is reassessed. Based on the results of the second assessment of the pigment, the production of polyvinyl chloride fluorite coating is optimized and adjusted through a path iteration optimization mechanism.

[0005] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the collected real-time operation data of the production line is as follows: Based on the entire process of the coating production line, by deploying a sensor network to collect real-time operating parameters of the coating production line, and constructing the collected real-time operating parameters into a corresponding dataset, we have:

[0007] in, This represents the real-time operating parameters collected by the first sensor. Indicates the first Real-time operating parameters collected by several sensors, including the current stirring temperature parameter. Current stirring speed parameters Current pigment concentration parameters and current slurry viscosity parameters , This represents the set of real-time operating parameters collected by all sensors. This represents the total number of sensors in the sensor network.

[0008] As a preferred embodiment of the monitoring and management method for a polyvinyl chloride (PVC) fluorite coating production line described in this invention, wherein: based on historical safety production data, a set of safety production photos of the PVC fluorite coating production line is constructed, then... For the entire process of the coating production line, data that matches the current production line's execution time and complies with safe production practices are extracted from the historical database. This extracted data is then used to construct a safety production comparison data set for the polyvinyl chloride fluorite coating production line. Therefore,

This indicates the safe slurry viscosity parameter when the execution time of the coating production line is consistent.

[0010] As a preferred embodiment of the monitoring and management method for a polyvinyl chloride fluorite coating production line according to the present invention, the step of verifying real-time operating parameters based on the constructed safety production comparison dataset for the polyvinyl chloride fluorite coating production line specifically includes: Using a safety production comparison dataset from a polyvinyl chloride (PVC) fluorite coating production line as a benchmark template, abnormal operating parameters are deleted by detecting the similarity between real-time operating parameters and the benchmark template. Then, the cosine similarity between the real-time operating parameters and the parameters in the benchmark template is calculated. Simultaneously, a cosine similarity safety threshold is set, and real-time operating parameters are tested based on this threshold. If the calculated cosine similarity exceeds the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters exceed the safety parameters in the baseline template, the currently collected real-time operating parameters cannot meet the safe production of coatings, the currently collected real-time operating parameters are abnormal parameters, and the abnormal parameters are deleted from the real-time operating parameter set. If the calculated cosine similarity is lower than the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters are lower than the safety parameters in the benchmark template. The currently collected real-time operating parameters can ensure the safe production of coatings. The currently collected real-time operating parameters are normal parameters, and the normal parameters are retained in the real-time operating parameter set.

[0011] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the specific steps of constructing a color paste dispersion quality assessment model to dynamically assess the color paste dispersion quality are as follows: The constructed benchmark template is used as input data and fed into the pigment dispersion quality assessment model to formulate a dynamic standard for pigment dispersion quality assessment. Based on the standard values ​​of pigment dispersion quality under different parameters, the real-time operating parameters are used to evaluate the pigment dispersion quality. Based on the constructed standard vector of pigment dispersion quality, a comprehensive score for pigment dispersion quality is constructed. A comprehensive evaluation of the pigment dispersion quality is conducted based on the difference between the constructed comprehensive score for pigment dispersion quality and the comprehensive score for pigment dispersion quality corresponding to the real-time operating parameters.

[0012] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the dynamic standard for evaluating the dispersion quality of the color paste is specifically as follows: Arbitrarily select one parameter from the benchmark template and keep the remaining parameters at a fixed value. Based on the selected parameter, use the parameter as input data for the color paste dispersion quality assessment model. According to the output of the model, determine the standard value of the color paste dispersion quality under the selected parameter. By selecting one parameter from the baseline template each time, and sequentially determining the standard value of the pigment dispersion quality for all parameters, we can obtain the following: Set the standard values ​​for the dispersion quality of the pigment paste under the safe stirring temperature parameter, the standard values ​​for the dispersion quality of the pigment paste under the safe stirring speed parameter, the standard values ​​for the dispersion quality of the pigment paste under the safe pigment paste concentration parameter, and the standard values ​​for the dispersion quality of the pigment paste under the safe slurry viscosity parameter in the reference template.

[0013] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the evaluation of the color paste dispersion quality under real-time operating parameters is specifically as follows: By constructing a standard vector of pigment dispersion quality based on the standard values ​​of pigment dispersion quality under different parameters, we have:

This represents the standard value of the pigment dispersion quality under the safe stirring temperature parameters in the reference template. This represents the standard value of the pigment dispersion quality under the safe stirring speed parameter in the reference template. This represents the standard value of the pigment dispersion quality under the safe pigment concentration parameter in the reference template. This represents the standard value indicating the quality of pigment dispersion under the safe slurry viscosity parameter in the reference template.

[0015] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the comprehensive evaluation of the color paste dispersion quality is specifically as follows: based on the constructed comprehensive score of color paste dispersion quality... And the comprehensive score of pigment dispersion quality corresponding to real-time operating parameters. The difference between them is used to comprehensively evaluate the dispersion quality of the pigment paste, specifically:

[0016] in, This represents the comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters. This represents the overall score of the dispersion quality of the constructed pigment paste. This represents the difference between the comprehensive score for pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score for pigment dispersion quality. This difference is used for a comprehensive evaluation of pigment dispersion quality. Specifically: If the difference between the calculated comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality is higher than 1 times the constructed comprehensive score of pigment dispersion quality, it indicates that the pigment dispersion quality corresponding to the real-time operating parameters is substandard. If the difference between the calculated comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality is less than 1 times the constructed comprehensive score of pigment dispersion quality, it indicates that the pigment dispersion quality corresponding to the real-time operating parameters meets the quality standard.

[0017] As a preferred embodiment of the polyvinyl chloride fluorite coating production line monitoring and management method of the present invention, the feedback optimization and adjustment of polyvinyl chloride fluorite coating production is specifically as follows: For real-time operating parameters whose pigment dispersion quality assessment results are substandard, one real-time operating parameter is adjusted each time, and based on the adjusted real-time operating parameter, the comprehensive pigment dispersion quality score corresponding to the real-time operating parameter is recalculated. The difference between this recalculated score and the constructed comprehensive pigment dispersion quality score is then calculated. The process involves sequentially calculating the comprehensive score of pigment dispersion quality corresponding to each adjusted real-time operating parameter, comparing it with the constructed comprehensive score of pigment dispersion quality, and then arranging the results in descending order. The maximum difference between the comprehensive score of pigment dispersion quality corresponding to the adjusted real-time operating parameter and the constructed comprehensive score of pigment dispersion quality is then identified. Based on the largest difference in positioning, the pigment dispersion quality is reassessed, and then... The maximum difference between the overall pigment dispersion quality score corresponding to the adjusted real-time operating parameters and the constructed overall pigment dispersion quality score is... The overall score for the dispersion quality of the pigment paste was less than that of the constructed pigment paste. If the value is 0, it indicates that the feedback adjustment for the current production of polyvinyl chloride fluorite coating is complete; otherwise, it indicates that the feedback adjustment is not complete.

[0019] The beneficial effects of this invention are: This invention, by deploying a pigment dispersion quality assessment module, and based on a comparison mechanism between model input and a safety template, as well as a quality scoring standard vector construction mechanism, achieves dynamic calculation and compliance judgment of pigment quality under real-time operating parameters in the production line. This overcomes the problems of strong lag and unstable assessment in traditional manual visual inspection and periodic testing methods. By constructing a parameter sensitivity gradient function and combining it with the dynamic adjustment mechanism of the weight coefficient of each operating parameter in the feedback adjustment module, the substandard quality status in the coating production process is gradually corrected and the path is optimized, ensuring the automatic control capability of the production line and improving production stability. By constructing a standardized quality assessment method with "benchmark template + weight coefficient + comprehensive score" as its core, a structured and quantitative expression of coating dispersion quality was achieved, providing algorithmic and mechanism support for subsequent standard transfer and quality benchmarking across equipment, batches, and workshops.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

[0022] Reference Figure 1 This is the first embodiment of the present invention, which provides a method for monitoring and managing a polyvinyl chloride fluorite coating production line, including the following steps: S1: Collect production line operation data in real time and dynamically evaluate the color paste dispersion quality based on the collected operation data.

[0023] Specifically, the dynamic evaluation of pigment dispersion quality is based on collected real-time production line operation data. A pigment dispersion quality evaluation model is constructed, using the collected real-time operation data as input and the model's output to dynamically evaluate the pigment quality. The specific implementation is as follows: Based on the entire process of the coating production line, by deploying a sensor network to collect real-time operating parameters of the coating production line, and constructing the collected real-time operating parameters into a corresponding dataset, we have:

Indicates the first Real-time operating parameters collected by several sensors, including the current stirring temperature parameter. Current stirring speed parameters Current pigment concentration parameters and current slurry viscosity parameters , This represents the set of real-time operating parameters collected by all sensors. This represents the total number of sensors in the sensor network.

[0026] Based on historical safety production data, a safety production comparison data set for the polyvinyl chloride fluorite coating production line was constructed, which yielded the following results: For the entire process of the coating production line, data that matches the current production line's execution time and complies with safe production practices are extracted from the historical database. This extracted data is then used to construct a safety production comparison data set for the polyvinyl chloride fluorite coating production line. Therefore,

[0027] in, This represents a safety production comparison dataset for a polyvinyl chloride (PVC) fluorite coating production line. This indicates the safe stirring temperature parameter corresponding to the execution time of the coating production line. This indicates the safe stirring speed parameter corresponding to the execution time of the paint production line. This indicates the safe pigment concentration parameter corresponding to the execution time of the paint production line. This indicates the safe slurry viscosity parameter when the execution time of the coating production line is consistent.

[0028] It should be noted that the extraction of data that is consistent with the current execution time of the coating production line and complies with safe production is based on the real-time operation data of the entire coating production line during the collection process. The data is extracted from the historical database based on the execution progress of the coating production line, and the generated parameter data is the data of safe production.

[0029] The dynamic evaluation of pigment dispersion quality based on the collected real-time operating parameter set is achieved through a two-layer evaluation mechanism. This includes real-time operating parameter verification based on a constructed safety production comparison dataset for PVC fluorite coating production lines, and dynamic evaluation of pigment dispersion quality by constructing a pigment dispersion quality evaluation model. The specific implementation is as follows: Real-time operating parameters were verified based on the constructed safety production comparison dataset for the PVC fluorite coating production line. This dataset served as a baseline template, and by detecting the similarity between the real-time operating parameters and the baseline template, abnormal operating parameters were removed. This provides an accurate data foundation for subsequent evaluation of pigment dispersion quality. The specific verification process is as follows: Calculate the cosine similarity between the real-time running parameters and the parameters in the baseline template. Simultaneously, set a safety threshold for the cosine similarity and perform real-time running parameter verification based on this threshold. Then, we have... If the calculated cosine similarity exceeds the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters exceed the safety parameters in the baseline template, the currently collected real-time operating parameters cannot meet the safe production of coatings, the currently collected real-time operating parameters are abnormal parameters, and the abnormal parameters are deleted from the real-time operating parameter set. If the calculated cosine similarity is lower than the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters are lower than the safety parameters in the benchmark template. The currently collected real-time operating parameters can ensure the safe production of coatings. The currently collected real-time operating parameters are normal parameters, and the normal parameters are retained in the real-time operating parameter set.

[0030] The dynamic evaluation of pigment dispersion quality is achieved by constructing a pigment dispersion quality assessment model. This involves building the model and using real-time operating parameters validated through a benchmark template as input data. The dynamic evaluation of pigment dispersion quality is then performed based on the model's output. The specific evaluation is as follows: The constructed benchmark template is used as input data and fed into the pigment dispersion quality assessment model to achieve dynamic standard setting for pigment dispersion quality assessment, specifically: Arbitrarily select one parameter from the benchmark template and keep the remaining parameters at a fixed value. Based on the selected parameter, use the parameter as input data for the color paste dispersion quality assessment model. According to the output of the model, determine the standard value of the color paste dispersion quality under the selected parameter. By selecting one parameter from the baseline template each time, and sequentially determining the standard value of the pigment dispersion quality for all parameters, we can obtain the following: The standard value for the dispersion quality of the pigment paste under the safe stirring temperature parameter in the benchmark template is set to... The standard value of the pigment dispersion quality under the safe stirring speed parameter in the reference template is The standard value of the pigment dispersion mass under the safe pigment concentration parameter in the reference template is Furthermore, the standard value for the dispersion quality of the pigment paste under the safe slurry viscosity parameter in the reference template is... .

[0031] Based on the standard values ​​of pigment dispersion quality under different parameters, the real-time operating parameters are used to evaluate the pigment dispersion quality. Specifically: By constructing a standard vector of pigment dispersion quality based on the standard values ​​of pigment dispersion quality under different parameters, we have:

[0032] in, This represents the constructed standard vector of pigment dispersion quality. This represents the standard value of the pigment dispersion quality under the safe stirring temperature parameters in the reference template. This represents the standard value of the pigment dispersion quality under the safe stirring speed parameter in the reference template. This represents the standard value of the pigment dispersion quality under the safe pigment concentration parameter in the reference template. The standard value representing the quality of pigment dispersion under the safe slurry viscosity parameter in the reference template; Based on the constructed standard vector of pigment dispersion quality, a comprehensive score for pigment dispersion quality is constructed, then:

[0033] in, Indicates parameters The weighting coefficients are set by the implementers based on the actual application scenario. Indicates parameters The corresponding standard value of pigment dispersion quality, This represents the overall score for the dispersion quality of the constructed pigment paste.

[0034] The collected real-time operating parameters are used as input data and fed into the pigment dispersion quality assessment model to obtain the comprehensive pigment dispersion quality score corresponding to the real-time operating parameters. ; Based on the comprehensive score of pigment dispersion quality constructed And the comprehensive score of pigment dispersion quality corresponding to real-time operating parameters. The difference between them is used to comprehensively evaluate the dispersion quality of the pigment paste, specifically:

[0035] in, This represents the comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters. This represents the overall score of the dispersion quality of the constructed pigment paste. This represents the difference between the comprehensive score for pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score for pigment dispersion quality. This difference is used for a comprehensive evaluation of pigment dispersion quality. Specifically: If the difference between the calculated comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality satisfies the formula... If the difference between the comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality exceeds 1 times the constructed comprehensive score of pigment dispersion quality, then the pigment dispersion quality corresponding to the real-time operating parameters is substandard. If the difference between the calculated comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality satisfies the formula... If the difference between the comprehensive score of pigment dispersion quality corresponding to the real-time operating parameters and the constructed comprehensive score of pigment dispersion quality is less than 1 times the constructed comprehensive score of pigment dispersion quality, then the pigment dispersion quality corresponding to the real-time operating parameters meets the quality standard.

[0036] S2: Based on the evaluation results of pigment dispersion quality, feedback is used to adjust the production of polyvinyl chloride fluorite coating.

[0037] Specifically, the feedback regulation of PVC fluorite coating production is based on the results of pigment dispersion quality assessment. The weighting coefficients of the parameters are dynamically adjusted, and the pigment quality is reassessed. Based on the results of the secondary assessment, an iterative path optimization mechanism is used to optimize the production of PVC fluorite coating until the best effect is achieved. The specific implementation is as follows: For the real-time operating parameters that fail to meet the quality standards in the pigment dispersion quality assessment results, the corresponding real-time parameters are calculated, and their sensitivity to the gradient of pigment quality assessment is determined.

[0038] in, This represents the overall score of the dispersion quality of the constructed pigment paste. This represents the set of real-time operating parameters collected by all sensors. This refers to the parameters in the real-time running parameters. , Indicates parameters Compared to the gradient sensitivity used for pigment quality assessment, the weighting coefficients of the parameters are dynamically adjusted as follows: Based on the substandard quality assessment results of the pigment paste, the gradient sensitivity of all parameters in the real-time operation parameters relative to the pigment paste quality assessment is calculated sequentially. The gradient sensitivity of all parameters is then rearranged in descending order. Simultaneously, the weight coefficients of all parameters are dynamically adjusted according to the rearranged order. Furthermore, the weight coefficients of the adjusted parameters are dynamically adjusted in descending order according to the gradient sensitivity.

[0039] Based on the weighting coefficients corresponding to the adjusted parameters, the pigment dispersion quality is reassessed, specifically as follows: For each of the collected real-time operating parameters, a control parameter is set. This indicates that the parameters in the real-time running parameter set are being considered. , parameters Adjusted to The specific values ​​are set by the implementers based on the actual application scenario; Based on the set control parameters, adjust the real-time operating parameters, and then re-evaluate the pigment dispersion quality based on the adjusted real-time operating parameters, specifically as follows: For real-time operating parameters whose pigment dispersion quality assessment results are substandard, one real-time operating parameter is adjusted each time, and based on the adjusted real-time operating parameter, the comprehensive pigment dispersion quality score corresponding to the real-time operating parameter is recalculated. The difference between this recalculated score and the constructed comprehensive pigment dispersion quality score is then calculated. The process involves sequentially calculating the comprehensive score of pigment dispersion quality corresponding to each adjusted real-time operating parameter, comparing it with the constructed comprehensive score of pigment dispersion quality, and then arranging the results in descending order. The maximum difference between the comprehensive score of pigment dispersion quality corresponding to the adjusted real-time operating parameter and the constructed comprehensive score of pigment dispersion quality is then identified. Based on the largest difference in positioning, the pigment dispersion quality is reassessed, and then...

The overall score of the pigment dispersion quality was determined by the combined score of the pigments. The comparison results satisfy the formula If the result is 0, it means that the color paste dispersion quality assessment results corresponding to all adjusted real-time operating parameters are up to standard, and the current adjustment of each parameter has reached the optimal adjustment result, and the feedback adjustment of the current polyvinyl chloride fluorite coating production is completed. The maximum difference between the overall pigment dispersion quality score corresponding to the adjusted real-time operating parameters and the constructed overall pigment dispersion quality score is... The overall score of the pigment dispersion quality was determined by the combined score of the pigments. The comparison results satisfy the formula If the result is negative, it means that the pigment dispersion quality results corresponding to all adjusted real-time operating parameters are substandard. This indicates that the adjustment of each real-time operating parameter has failed to meet the production requirements of PVC fluorite coating. The control parameters should be reset, the real-time operating parameters should be adjusted again, and the pigment dispersion quality corresponding to the adjusted real-time operating parameters should be re-evaluated until the maximum difference between the comprehensive pigment dispersion quality score corresponding to the readjusted real-time operating parameters and the constructed comprehensive pigment dispersion quality score is found. The overall score of the pigment dispersion quality was determined by the combined score of the pigments. The comparison results satisfy the formula This indicates that the feedback adjustment for the current production of polyvinyl chloride fluorite coating has been completed. Example 2

If the calculated cosine similarity exceeds the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters exceed the safety parameters in the baseline template, the currently collected real-time operating parameters cannot meet the safe production of coatings, the currently collected real-time operating parameters are abnormal parameters, and the abnormal parameters are deleted from the real-time operating parameter set. If the calculated cosine similarity is lower than the set cosine similarity safety threshold, it means that the currently collected real-time operating parameters are lower than the safety parameters in the benchmark template. The currently collected real-time operating parameters can ensure the safe production of coatings. The currently collected real-time operating parameters are normal parameters, and the normal parameters are retained in the real-time operating parameter set.

The difference between this recalculated score and the constructed comprehensive pigment dispersion quality score is then calculated. Calculate the difference between the overall pigment dispersion quality score corresponding to each adjusted real-time operating parameter and the constructed overall pigment dispersion quality score. Arrange the results in descending order and locate the largest difference between the overall pigment dispersion quality score corresponding to the adjusted real-time operating parameter and the constructed overall pigment dispersion quality score. Based on the largest difference in the positioning, the pigment dispersion quality is reassessed.

The overall score for the dispersion quality of the pigment paste was less than that of the constructed pigment paste. If the value is 0, it indicates that the feedback adjustment for the current production of polyvinyl chloride fluorite coating is complete; otherwise, it indicates that the feedback adjustment is not complete.
