Description

Technical Field

[0001] The present invention relates to the technical field of computer systems, and in particular to a method and system for monitoring process equipment parameters of coating liquid concentration 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 the tobacco itself, and do not involve the research on the indicators and / or equipment process parameters that are correlated with the sensory quality of the reconstituted tobacco in the preparation process of cigarettes, especially 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 the reconstituted tobacco leaves in real time during the preparation process.

[0007] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0090] The standard coating solution concentration interval is set to 60.0%±10.0%.

[0091] Based on the hardware architecture of the papermaking reconstituted tobacco system of the above-mentioned computer system technology, an embodiment of the coating liquid concentration process equipment parameter monitoring method based on sensory quality scoring of the present application is proposed.

[0092] Reference Figure 2 In a first embodiment, the method for monitoring process equipment parameters of coating liquid concentration based on sensory quality score comprises the following steps:

[0093] 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 the concentration of the coating liquid;

[0094] In this embodiment, the sensory quality score of the reconstituted tobacco to be tested is firstly obtained.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] For example, see Figure 3 A schematic diagram of the fitting curve between the coating solution concentration and the sensory evaluation score is shown.

[0100] 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:

[0101] Table 1. Correspondence between correlation coefficient and correlation strength

[0102] Correlation coefficient Strength of association 0.8-10 Very strong correlation 0.6-0.8 Strong correlation 0.4-0.6 Moderately strong correlation 0.2-0.4 Weak correlation 0.0-0.2 Very weak or no correlation

[0103] Based on the relationship correspondence table given in Table 1, the correlation coefficient of the coating liquid concentration is 0.818.

[0104] Furthermore, after determining that the associated process parameter is the coating liquid concentration, during the papermaking reconstituted tobacco production process, the system collects the coating liquid concentration in the reconstituted tobacco in real time, and inputs the coating liquid concentration 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 liquid concentration in the sensory quality score calculation model simulates and predicts the sensory quality score value corresponding to the coating liquid concentration.

[0105] 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 a large number of coating liquid concentrations of reconstituted tobacco leaves produced in historical batches, and scored these reconstituted tobacco leaves through manual smoking, and obtained a correlation table covering a large number of coating liquid concentrations and sensory quality scores of reconstituted tobacco leaves. Figure 4 This is a schematic diagram of the correlation between the coating liquid concentration and the 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 92.3%.

[0106] It should be noted that the specific sensory quality score calculation model, which is based on the coating liquid concentration, is not the 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.

[0107] Step S20, when it is detected that the sensory quality score value is not in the normal value range, determining whether the coating liquid concentration of the reconstituted tobacco leaf to be tested is in the standard coating liquid concentration range;

[0108] Step S30: If not, determine and output the abnormal target coating liquid concentration process equipment parameters among the coating liquid concentration process equipment parameters.

[0109] 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 liquid concentration of the reconstituted tobacco leaves to be tested is abnormal. The coating liquid concentration is used as the target tobacco leaf process parameter to be tested for detection. When it is determined that the coating liquid concentration is not in its corresponding standard coating liquid concentration interval, the abnormal target coating liquid concentration process equipment parameters among the coating liquid concentration process equipment parameters are determined and output.

[0110] Optionally, the normal value interval of the sensory quality score can be set to a fixed value of ±1; wherein the fixed value can be set according to the specific processing scenario of the reconstituted tobacco leaves.

[0111] Further, in this embodiment, when it is determined that the coating liquid concentration is not within the normal value range, the coating liquid concentration 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 liquid concentration in the papermaking method reconstituted tobacco process. The specific coating liquid concentration and the corresponding abnormal target reconstituted tobacco equipment parameters are described in subsequent embodiments and will not be repeated here.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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 liquid concentration 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.

[0116] In the actual papermaking process of reconstituted tobacco leaves, we allow a certain fluctuation in the numerical range of the coating liquid concentration of the reconstituted tobacco leaves. Therefore, even if the coating liquid concentration 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 liquid concentration as an abnormal process parameter. In other words, the coating liquid concentration is only regarded as an abnormal process parameter when it is monitored that the sensory quality score value predicted based on the coating liquid concentration is abnormal and the coating liquid concentration value is also abnormal.

[0117] 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 liquid concentration is abnormal, and when the coating liquid concentration is abnormal, the abnormal equipment parameters related to the coating liquid concentration 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.

[0118] Second embodiment

[0119] In this embodiment, step S20 includes:

[0120] Step S21, obtaining the Brix value of the coating liquid concentration acquisition device, using the Brix value as the coating liquid concentration, or obtaining the concentration data collected and converted by the mass transmitter, and determining the coating liquid concentration according to the concentration data;

[0121] Step S22, determining whether the coating liquid concentration is within a standard coating liquid concentration range.

[0122] In this embodiment, the coating liquid concentration can be acquired by collection or calculation. The Brix value can be used to reflect the coating liquid concentration for monitoring and measurement, or it can be collected and converted by a mass transmitter to present a specific concentration value.

[0123] Third embodiment

[0124] Reference Figure 5 In this embodiment, based on the first or second embodiment, step S30 includes:

[0125] Step S311, determining whether the coating liquid concentration process equipment parameter is within a preset standard parameter range, if not, determining the coating liquid concentration process equipment parameter as the abnormal target coating liquid concentration process equipment parameter and outputting it;

[0126] Alternatively, in step S312, each of the coating liquid concentration process equipment parameters is output as the abnormal target coating liquid concentration process equipment parameter.

[0127] This embodiment provides two different abnormal target coating liquid concentration process equipment parameter judgment schemes:

[0128] 1. A standard parameter range is preset for each coating liquid concentration 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.

[0129] Second, each process equipment parameter is directly regarded as abnormal and output as the abnormal process equipment parameter.

[0130] 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.

[0131] 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.

[0132] Fourth embodiment

[0133] In this embodiment, based on any of the foregoing embodiments, the coating liquid concentration process equipment parameter includes a paper machine speed, which 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 coating liquid concentration, and the step S30 includes:

[0134] Step S32, collecting the running speed of the paper machine as the speed of the paper machine;

[0135] Step S331, 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 liquid concentration process equipment parameter and outputting it;

[0136] Alternatively, in step S332, the paper machine speed is output as the abnormal target coating liquid concentration process equipment parameter.

[0137] Fifth embodiment

[0138] In this embodiment, based on any of the foregoing embodiments, the coating liquid concentration process equipment parameters include the coating liquid preparation concentration, which refers to the concentration of the concentrated liquid after the tobacco extract is evaporated and concentrated, and can be directly expressed and collected by the Brix value, which is positively correlated with the coating liquid concentration.

[0139] The step S30 comprises:

[0140] Step S34, collecting the Brix value of the tobacco extract after evaporation and concentration by the coating liquid preparation system;

[0141] Step S35, determining the concentration of the coating solution according to the Brix value;

[0142] Step S361, determining whether the coating liquid preparation concentration is within the standard coating liquid preparation concentration range, if not, determining the coating liquid preparation concentration as the abnormal target coating liquid concentration process equipment parameter and outputting it; or,

[0143] Step S362: outputting the coating liquid preparation concentration as the abnormal target coating liquid concentration process equipment parameter.

[0144] Sixth embodiment

[0145] In this embodiment, based on any of the above embodiments, the coating liquid concentration process equipment parameters include cycle time, which refers to the circulation time of the coating liquid in the coating machine tank, and can be controlled by the coating liquid supply pump and the coating liquid tank liquid level linkage. The principle is that the film substrate will preferentially take away water through the coating liquid tank, thereby increasing the coating liquid concentration in the coating liquid tank, so it is positively correlated with the coating liquid concentration. The step S30 includes:

[0146] Step S37, obtaining the circulation time of the coating liquid in the coating liquid tank recorded by the coating machine as the circulation time;
