Description

Technical Field

[0001] The present application relates to the technical field of computer systems, and in particular to a method and system for monitoring coating rate process equipment parameters based on sensory quality scoring. Background Art

[0002] Reconstituted tobacco is an important part of the tobacco industry, and its quality directly affects the quality of tobacco products. The national standard GB 5606.4-2005 "Cigarettes Part 4: Sensory Technical Requirements" stipulates several rules for judging the sensory quality of cigarettes, and evaluates the sensory quality of cigarettes from aspects such as the appearance, smoke, and aroma of tobacco leaves.

[0003] However, manual smoking evaluation usually involves sampling several cigarettes from a production batch, testing the parameters related to the sensory quality of the cigarettes using chemical experiments, and then combining the subjective judgment of professional smoking testers on the appearance, smoke, aroma and other aspects of the tobacco leaves to score the sensory quality of the cigarettes. If the score is unqualified, all cigarettes in the production batch will be judged as unqualified.

[0004] Related technical solution 1, Chinese patent publication number CN117422330A discloses a method for evaluating the quality of ordinary cigarette tobacco, which discloses the following indicators for evaluating the quality of tobacco: 1. Leaf quality indicators (including leaf moisture content, leaf filling value, leaf whole rate and leaf broken rate); 2. Cigarette physical indicators (including cigarette unit weight, cigarette unit weight standard deviation, cigarette draw resistance, cigarette draw resistance standard deviation, cigarette filter ventilation rate and cigarette filter ventilation rate standard deviation); 3. Smoke indicators (including tar release extremes, carbon monoxide release extremes and smoke nicotine release extremes); 4. Sensory indicators (including gloss, aroma, harmony, miscellaneous smell, irritation and aftertaste). The score of each indicator corresponds to a different weight. The final comprehensive evaluation score of tobacco is obtained by multiplying each indicator by its own weight and adding them together.

[0005] Related technical solution 2, Chinese patent publication number CN110458474A discloses a comprehensive evaluation method for the physical quality of cigarette rolling, which discloses the following 7 indicators for evaluating the quality of cut tobacco: support weight, draw resistance, hardness, ventilation rate, end cut tobacco, dust content and empty head rate. Through data collection, data standardization processing, and principal component analysis of standardized data, a batch of cigarette comprehensive physical quality evaluation model is established, and the cigarette rolling quality is quantitatively scored through the evaluation model.

[0006] However, the above-mentioned related technical solutions all focus on analyzing the indicators of tobacco itself, and do not involve the research on indicators and / or equipment process parameters that are correlated with the sensory quality of reconstituted tobacco in the preparation process of cigarettes, especially in the preparation process of reconstituted tobacco leaves; in addition, the above-mentioned technical solutions can only collect samples for testing after a large number of products in the same batch are prepared, and it is impossible to monitor the quality control of reconstituted tobacco leaves in real time during the preparation process. The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is recognized as prior art. Summary of the invention

[0095] The standard coating rate range is 42.0%±5.0%.

[0096] Based on the hardware architecture of the papermaking reconstituted tobacco system of the above-mentioned computer system technology, an embodiment of the coating rate process equipment parameter monitoring method based on sensory quality scoring of the present application is proposed.

[0097] Reference Figure 2 In a first embodiment, the method for monitoring coating rate process equipment parameters based on sensory quality score comprises the following steps:

[0098] Step S10, obtaining a sensory quality score value of the reconstituted tobacco to be tested, wherein the sensory quality score value is a predicted value calculated based on the sensory quality score-related process parameters of the reconstituted tobacco, and the sensory quality score-related process parameters of the reconstituted tobacco include a coating rate;

[0099] In this embodiment, the sensory quality score of the reconstituted tobacco to be tested is firstly obtained.

[0100] It should be noted that the reconstituted tobacco leaves to be tested refer to the reconstituted tobacco leaves that have gone through the reconstituted tobacco process and are waiting to be tested to see if their quality meets the sensory quality standards.

[0101] Optionally, the reconstituted tobacco leaves to be tested can be sampled from a product batch previously produced in the production batch, as the reconstituted tobacco leaves to be tested.

[0102] It should be noted that the sensory quality score is a predicted value calculated based on the process parameters associated with the sensory quality score of reconstituted tobacco leaves, that is, the system calculates the predicted value through a deep learning model based on the process parameters that affect the sensory quality of reconstituted tobacco leaves during the preparation process of papermaking reconstituted tobacco leaves, rather than a score value after manual smoking evaluation.

[0103] In this embodiment, in order to study which parameters are "associated process parameters" that are strongly correlated with the sensory quality score of papermaking reconstituted tobacco, corresponding statistics are performed based on the existing production database Uniformence and combined with the actual sensory quality manual smoking scores, thereby determining the fitting curve in the tobacco process parameters.

[0104] For example, see Figure 3 A schematic diagram of the fitting curve of the coating rate and sensory evaluation score is shown.

[0105] After determining the fitting curve, Minitab was further used to perform correlation analysis on the key process parameters involved, referring to the corresponding table between the correlation coefficient and the correlation strength shown in Table 1:

[0106] Table 1. Correspondence between correlation coefficient and correlation strength

[0107]

[0108]

[0109] Based on the relationship correspondence table given in Table 1, the correlation coefficient of the coating rate is 0.874.

[0110] Furthermore, after determining that the associated process parameter is the coating rate, during the papermaking reconstituted tobacco production process, the system collects the coating rate in the reconstituted tobacco in real time, and inputs the coating rate into the trained sensory quality score calculation model constructed based on the deep learning model. The sensory quality score calculation module based on the coating rate in the sensory quality score calculation model simulates and predicts the sensory quality score value corresponding to the coating rate.

[0111] In order to ensure that the sensory quality score calculated by the model is close enough to the sensory quality score after manual smoking, during the training process, we collected the coating rates of a large number of reconstituted tobacco leaves produced in historical batches, and scored these reconstituted tobacco leaves through manual smoking, and obtained a correlation table covering the coating rate and sensory quality score of a large number of reconstituted tobacco leaves. Figure 4 This is a schematic diagram of the correlation between the coating rate and sensory quality score of reconstituted tobacco leaves selected from the correlation table (the specific values ​​of the sensory quality score are omitted due to industrial secrets). Using the data in this correlation table, multiple deep learning training and algorithm optimization were carried out. After testing, the accuracy of the final model reached 91.6%.

[0112] It should be noted that the specific construction method of the sensory quality score calculation module based on the coating rate in the sensory quality score calculation model is not the public focus of this proposal. This proposal aims to explain the correlation between the sensory quality score and the sensory quality process parameters of reconstituted tobacco leaves.

[0113] Step S20, when it is detected that the sensory quality score value is not in the normal value range, determining whether the coating rate of the reconstituted tobacco leaf to be tested is in the standard coating rate range;

[0114] Step S30: If not, determine and output the abnormal target coating rate process equipment parameters among the coating rate process equipment parameters.

[0115] In this embodiment, after obtaining the sensory quality score value of the reconstituted tobacco leaves to be tested, it is determined whether the numerical interval of the sensory quality score value is in the normal value interval. When it is detected that the sensory quality score value is not in the normal value interval, it is determined that the coating rate of the reconstituted tobacco leaves to be tested is abnormal. The coating rate is used as the target tobacco leaf process parameter to be tested for detection. When it is determined that the coating rate is not in its corresponding standard coating rate interval, the abnormal target coating rate process equipment parameters among the coating rate process equipment parameters are determined and output.

[0116] Optionally, the normal value interval of the sensory quality score can be set to a fixed value ±1; wherein the fixed value can be set according to the specific processing scenario of the reconstituted tobacco leaves.

[0117] Further, in this embodiment, when it is determined that the coating rate is not within the normal value range, the coating rate corresponds to one or more target reconstituted tobacco equipment parameters, and the target reconstituted tobacco equipment parameters refer to the parameters corresponding to the equipment that affects the coating rate in the papermaking method reconstituted tobacco process. The specific coating rate and the corresponding abnormal target reconstituted tobacco equipment parameters are described in subsequent embodiments and will not be repeated here.

[0118] Optionally, in some embodiments, the output method can be to display the specific abnormal tobacco leaf process parameter name, the equipment information of the abnormal equipment, and the corresponding operating parameter name of the equipment to the background user terminal, and the staff will promptly execute the corresponding emergency handling strategy after receiving this information in the background.

[0119] Optionally, in some embodiments, the output method can also be to send a prompt message to the monitoring end in the process link where the abnormal tobacco process parameters are located, so as to alert the supervisor in the process link that the operating parameters of the equipment in the link are abnormal.

[0120] Optionally, in some embodiments, the output method can also be to send the abnormal target reconstituted tobacco equipment parameters to the intelligent control end of the system, and the intelligent control end adjusts the equipment parameters according to the abnormal target reconstituted tobacco equipment parameters to restore it to normal operating parameters.

[0121] In addition, it should be noted that, in the present embodiment, the reason why the quality control stability of the reconstructed tobacco leaves in the papermaking process is monitored by monitoring the value of the sensory quality score, rather than directly monitoring according to the value of the coating rate, is that there are a variety of quality monitoring indicators in the production process of reconstructed tobacco leaves, but the general monitoring indicators are only for assessing the output grade of the reconstructed tobacco leaves, which does not affect whether the reconstructed tobacco leaves are qualified; and the sensory quality score value is an indicator with a veto nature as to whether the production of the reconstructed tobacco leaves is qualified.

[0122] In the actual papermaking process of reconstituted tobacco leaves, we allow a certain fluctuation in the numerical range of the coating rate of reconstituted tobacco leaves. Therefore, even if the coating rate value of a batch of reconstituted tobacco leaves deviates from the preset numerical range, but does not cause the sensory quality score value monitored by the system to deviate from the normal value range, we still regard the output of this batch of reconstituted tobacco leaves as qualified, and do not regard the coating rate as an abnormal process parameter. In other words, the coating rate is only regarded as an abnormal process parameter when it is monitored that the sensory quality score value predicted based on the coating rate is abnormal and the coating rate value is also abnormal.

[0123] In the technical solution provided in this embodiment, by obtaining the sensory quality score value of the reconstituted tobacco to be tested calculated based on the process parameters associated with the sensory quality score of the reconstituted tobacco, when the sensory quality score value is abnormal, it is judged whether the coating rate is abnormal, and when the coating rate is abnormal, the abnormal equipment parameters related to the coating rate are output, thereby realizing real-time monitoring of the key parameters affecting the sensory quality score in the production process of papermaking reconstituted tobacco, and timely feedback when abnormalities occur, thereby ensuring product stability in the production process of papermaking reconstituted tobacco.

[0124] Second embodiment

[0125] Reference Figure 5 In this embodiment, based on the first embodiment, step S30 includes:

[0126] Step S311, determining whether the coating rate process equipment parameter is within a preset standard parameter range, if not, determining the coating rate process equipment parameter as the abnormal target coating rate process equipment parameter and outputting it;

[0127] Alternatively, in step S312, each of the coating rate process equipment parameters is output as the abnormal target coating rate process equipment parameter.

[0128] This embodiment provides two different abnormal target coating rate process equipment parameter judgment schemes:

[0129] 1. A standard parameter range is preset for each coating rate process equipment parameter to determine whether the value of the equipment parameter falls within the range. If not, it is determined to be an abnormal equipment parameter.

[0130] Second, each process equipment parameter is directly regarded as abnormal and output as the abnormal process equipment parameter.

[0131] For one solution, each parameter is set with a standard parameter range, and whether it is abnormal is judged based on the range, and only the abnormal ones are output.

[0132] For the second solution, each process equipment parameter is directly output as an abnormal equipment parameter, and the background staff checks each process equipment parameter one by one.

[0133] Third embodiment

[0134] In this embodiment, based on the first or second embodiment, the coating rate process equipment parameters include the absolute dry weight before coating, which also affects the coating rate, and the two are positively correlated. When the coating rate value is abnormal, the equipment parameters affecting the absolute dry weight before coating can be detected, including at least one of the sizing amount, retention rate, and base uniformity, and the absolute dry weight before coating is adjusted by adjusting the equipment parameters affecting the absolute dry weight before coating, thereby adjusting the coating rate value.

[0135] The sizing amount refers to the slurry flow rate required to meet the quantitative requirements. Optionally, a flow meter can be set in the slurry pipeline in the coating process, and the system can collect the sizing amount by collecting the flow data on the flow meter. Among them, the sizing amount is positively correlated with the absolute dry weight before coating within a certain numerical range.

[0136] Retention rate (also known as filler retention rate) refers to the proportion of fillers or fibers retained in paper during the papermaking process, that is, the percentage of fillers in paper to fillers in the slurry. Retention rate is positively correlated with the absolute dry weight before coating.

[0137] In addition, the retention rate is a calculated value, calculated as follows:

[0138] Retention rate = absolute dry weight of retained slurry / absolute dry weight of slurry * 100%

[0139] Among them, the absolute dry amount of retained slurry and the absolute dry amount of slurry are both the collection amounts of the system.

[0140] Wherein, the step S30 includes:

[0141] Step S32, determining the target process equipment parameters associated with the absolute dry weight before coating, wherein the target process equipment parameters include at least one of sizing amount, retention rate, and base uniformity;

[0142] Step S331, determining whether the target process equipment parameters are in the respective corresponding preset standard intervals, if not, determining the target process equipment parameters that are not in the preset standard interval as the abnormal target coating rate process equipment parameters; or,

[0143] Step S332: output the target process equipment parameters as the abnormal target coating rate process equipment parameters.

[0144] Furthermore, the target process equipment parameters are obtained by at least one of the following methods:

[0145] Obtaining flow data of a flow meter during an absolute dry quantitative process of a slurry pipeline before coating, and determining the sizing amount according to the flow data;

[0148] Fourth embodiment

[0149] In this embodiment, based on the first or second embodiment, the coating rate process equipment parameters include the absolute dry weight after coating, and the absolute dry weight after coating will also affect the size of the coating rate, and the two are positively correlated. When the coating rate value is abnormal, the equipment parameters affecting the absolute dry weight after coating can be detected, including at least one of the coating liquid concentration, coating roller pressure, additive usage, absolute dry weight before coating, paper machine speed, coating liquid temperature and base absorption performance value, and the absolute dry weight after coating is adjusted by adjusting the equipment parameters affecting the absolute dry weight after coating, thereby adjusting the numerical value of the coating rate.

[0150] The coating liquid concentration can be a collected value or a calculated value. The Brix value is used to reflect the coating liquid concentration for monitoring and measurement, or it can be collected and converted by a mass transmitter and presented as a specific concentration value. There is a positive correlation between the coating liquid concentration and the absolute dry weight after coating.

[0151] The coating roller pressure refers to the pressure value when the coating roller applies the coating to the surface of the base material, which can be directly collected by the system. Among them, the coating roller pressure is negatively correlated with the absolute dry weight after coating.

[0152] The amount of additives used refers to all substances in the middle coating liquid except the concentrated liquid, including flavors and fragrances, calcium carbonate, propylene glycol, glycerin, etc. Among them, calcium carbonate in the additives will directly increase the absolute dry weight after coating. Therefore, the amount of additives used is positively correlated with the absolute dry weight after coating.

[0153] In addition, the absolute dry weight before coating will also affect the absolute dry weight after coating, and the two are positively correlated. When the absolute dry weight after coating is abnormal, the equipment parameters that affect the absolute dry weight before coating (such as sizing amount, retention rate, base uniformity, etc.) can be detected, and the absolute dry weight before coating can be adjusted by adjusting the equipment parameters that affect the absolute dry weight before coating, thereby adjusting the absolute dry weight before coating, and then adjusting the value of the absolute dry weight after coating.

[0154] Paper machine speed refers to the running speed of the paper machine, which is determined by the driving roller of the paper machine's fourdrinier wire and can be directly collected by the system. The paper machine speed is negatively correlated with the absolute dry weight after coating.

[0155] In addition, the coating liquid temperature will also affect the size of the absolute dry weight after coating. When the coating liquid temperature increases, the coating liquid viscosity increases, and the absolute dry weight after coating will also increase. Therefore, when the absolute dry weight after coating is abnormal, the equipment parameters affecting the coating liquid temperature can be detected. By adjusting the equipment parameters affecting the coating liquid temperature, the coating liquid temperature can be adjusted, and then the value of the absolute dry weight after coating can be adjusted.

[0156] The base absorption performance value refers to the quantitative value of the base absorption performance, which is related to the material of the base and is positively correlated with the bulk thickness of the base within a certain numerical range. The base absorption performance value is a parameter value predetermined in the papermaking recycling process, and the base absorption performance value can be changed by changing the bulk thickness of the base. Under the same conditions, the better the base absorption performance, the higher the absolute dry weight after coating, but there is an extreme value. Therefore, the base absorption performance is positively correlated with the absolute dry weight after coating within a certain range.

[0157] Wherein, the step S30 includes:

[0158] Step S341, determining whether the absolute dry weight after coating is within the standard absolute dry weight after coating interval, if not, determining the second target process equipment parameter associated with the absolute dry weight after coating as the abnormal target coating rate process equipment parameter and outputting it, wherein the second target process equipment parameter includes at least one of coating liquid concentration, coating roller pressure, additive usage, absolute dry weight before coating, paper machine speed, coating liquid temperature and base absorption performance value; or,

[0159] Step S342, outputting the second target process equipment parameter associated with the absolute dry quantity after coating as the abnormal target coating rate process equipment parameter.

[0160] Fifth embodiment

[0161] In this embodiment, based on the first or second embodiment, the coating rate process equipment parameter includes coating roller pressure, which refers to the pressure value when the coating roller applies the coating to the surface of the base material, and can be directly collected by the system, wherein the coating roller pressure is negatively correlated with the coating rate. Wherein, the step S30 includes:

[0162] Step S35, collecting pressure data of a pressure sensor provided on the coating roller during the coating process;

[0163] Step S36, determining the coating roller pressure according to the pressure data;

[0164] Step S371, determining whether the coating roller pressure is in a standard coating roller pressure range, and if not, determining the coating roller pressure as the abnormal target coating rate process equipment parameter and outputting it;

[0165] Alternatively, in step S372, the coating roller pressure is output as the abnormal target coating rate process equipment parameter.

[0166] Sixth embodiment

[0167] In this embodiment, based on the first or second embodiment, the coating rate process equipment parameter includes the paper machine speed, and the paper machine speed is negatively correlated with the coating rate. The step S30 includes:

[0168] Step S38, collecting the running speed of the paper machine as the speed of the paper machine;

[0169] Step S391, determining whether the paper machine speed is in the standard paper machine speed range, if not, determining the paper machine speed as the abnormal target coating rate process equipment parameter and outputting it; or,

[0170] Step S392, outputting the paper machine speed as the abnormal target coating rate process equipment parameter.

[0171] Seventh embodiment

[0172] In this embodiment, based on the first or second embodiment, the coating rate process equipment parameter includes a base absorption performance value, and the base absorption performance is positively correlated with the coating rate within a certain range. The step S30 includes:

[0173] S310, obtaining a film base absorption performance value, wherein the film base absorption performance value is related to the bulk of the film base;

[0174] S3111, determining whether the film base absorption performance value is within the standard film base absorption performance value range, if not, determining the film base absorption performance value as the abnormal target coating rate process equipment parameter and outputting it;

[0175] Alternatively, S3112, the substrate absorption performance value is output as the abnormal target coating rate process equipment parameter.
