Description

Technical Field

[0001] The present application belongs to the technical field of cigar tobacco leaf processing, and in particular relates to a method and device for determining the fermentation endpoint of cigar core based on accumulated temperature and precipitation. Background Art

[0002] During the processing of cigar tobacco leaves, research has found that tobacco fermentation is one of the most important links in improving tobacco quality. After fermentation, tobacco leaves can convert and degrade macromolecular substances such as starch, protein and chlorophyll. As the color of the tobacco leaves becomes darker and the oil content becomes more prominent, unpleasant odors such as green smell, miscellaneous smell and irritation are reduced or even eliminated, and pleasant aroma such as fragrance is revealed, and the taste tends to be mellow, thereby effectively improving the quality of tobacco leaves.

[0003] At present, in the actual tobacco leaf fermentation process, the degree of tobacco leaf fermentation is mainly judged by manual smelling of the tobacco leaves and combining it with sensory quality evaluation. This is not only highly dependent on manual labor and subjectivity, resulting in low efficiency, but also cannot guarantee the fermentation quality of the tobacco leaves and the consistency of the fermentation degree. Summary of the Invention

[0048] See also Figure 1 , Figure 1 The overall flow chart of a method for determining the fermentation endpoint of cigar core based on accumulated temperature and precipitation provided in an embodiment of the present application is shown.

[0049] like Figure 1 As shown, the method for determining the fermentation endpoint of cigar core based on accumulated temperature and precipitation may include at least the following steps:

[0050] Step 102: Acquire an image to be processed containing two groups of cigar tobacco leaf stacks, and identify the filler portion of each group of cigar tobacco leaf stacks from the image to be processed.

[0051] In an embodiment of the present application, the method for determining the fermentation endpoint of cigar core based on accumulated temperature and precipitation can be but is not limited to being applied to a control terminal, which can establish connections with a cigar tobacco leaf stacking device, an industrial camera, a tobacco leaf moisture content detection device, and a temperature detection device, respectively, so that when multiple groups of cigar tobacco leaf stacks placed on the cigar tobacco leaf stacking device are fermented, the industrial camera is used to collect images to be processed containing two groups of cigar tobacco leaf stacks, and the cigar tobacco leaf stacking device is controlled to perform multiple stacking processes on the cigar tobacco leaf stack according to the identified core part, and during the stacking process, the tobacco leaf moisture content detection device and the temperature detection device can also be controlled to collect corresponding stack core moisture parameters and temperature parameters, respectively, and finally the fermentation endpoint moment of the cigar tobacco leaf stack is determined in combination with the core part, stack core moisture parameters, and temperature parameters. Among them, the moisture content parameter of the stack core can be understood as the moisture content corresponding to the tobacco leaves at the stack core position of the cigar tobacco leaf stack, and the temperature parameter can include but is not limited to the fermentation environment temperature collected at the same time and the tobacco leaf stack core temperature at the stack core position of the cigar tobacco leaf stack, and the above-mentioned cigar tobacco leaf stack turning device, industrial camera, tobacco leaf moisture content detection device and temperature detection device are all conventional application equipment in the field of cigar tobacco leaf fermentation processing technology, and their working principles and equipment structures will not be elaborated here.

[0052] It can be understood that when determining the end point of the fermentation process of a cigar tobacco leaf stack, the control terminal can specifically identify the core part of the cigar tobacco leaf stack during the fermentation process, and perform multiple stacking processes on the corresponding cigar tobacco leaf stack based on the core temperature threshold corresponding to the core part, and collect the core moisture parameters and at least two sets of temperature parameters under the stacking process to effectively ensure the fermentation quality and consistency of the fermentation degree of the tobacco leaves; in addition, the changes in these two indicators can be used to jointly determine the fermentation end point of the cigar tobacco leaf stack, which can greatly improve the objectivity, accuracy and timeliness of the tobacco leaf fermentation end point determination compared to manual work.

[0053] Specifically, when performing endpoint determination processing on the fermentation process of cigar tobacco leaf stacks, the control terminal can, but is not limited to, controlling the industrial camera arranged on the top of the cigar tobacco leaf stacking device to collect images to be processed containing the two groups of cigar tobacco leaf stacks after the two groups of cigar tobacco leaf stacks placed on the cigar tobacco leaf stacking device are fermented, so as to identify the core part of each group of cigar tobacco leaf stacks through image recognition and other methods. Here, a plurality of cigar leaf stacks distributed in an array can be placed on the cigar leaf stacking device, and one or more industrial cameras can respectively collect images to be processed containing two adjacent groups of cigar leaf stacks, so as to more accurately and effectively determine the fermentation endpoint time of the two groups of cigar leaf stacks from the perspective of the two adjacent groups of cigar leaf stacks. In addition, the industrial camera in the embodiment of the present application is not limited to collecting images to be processed containing multiple adjacent groups of cigar leaf stacks, so as to more accurately and effectively determine the fermentation endpoint time of the multiple groups of cigar leaf stacks from the perspective of the multiple adjacent groups of cigar leaf stacks, thereby improving the overall processing efficiency of the cigar leaf stacks on the cigar leaf stacking device.

[0054] It can be understood that the filler part of each group of cigar tobacco leaf stacks can be any one of the top filler, middle filler or bottom filler. For example, the filler parts of two adjacent groups of cigar tobacco leaf stacks in the image to be processed can be any combination of the top filler, the middle filler, the bottom filler, the top filler and the middle filler, the middle filler and the bottom filler, and the top filler and the bottom filler.

[0055] As an option in the embodiment of the present application, identifying the filler portion of each group of cigar tobacco leaves from the image to be processed includes:

[0056] Extracting tobacco leaf contour features corresponding to each group of cigar tobacco leaf stacks from the image to be processed, and determining a sample tobacco leaf contour having the highest similarity to each tobacco leaf contour feature from a preset tobacco leaf contour-part database; wherein the preset tobacco leaf contour-part database includes at least two cigar filler parts and a sample tobacco leaf contour corresponding to each cigar filler part;

[0057] The cigar core part corresponding to the sample tobacco leaf contour with the highest similarity is used as the cigar core part of the corresponding cigar tobacco leaf stack.

[0058] Specifically, to ensure accurate identification of filler locations, when identifying the filler locations of each cigar stack from the image to be processed, the control terminal may utilize algorithms such as image feature extraction to extract tobacco leaf contour features corresponding to each cigar stack from the image to be processed. The control terminal may also calculate the similarity between each sample tobacco leaf contour in a preset tobacco leaf contour-location database and the tobacco leaf contour features corresponding to each cigar stack, with the sample tobacco leaf contour feature with the highest similarity being deemed the tobacco leaf contour feature with the highest degree of match to the corresponding cigar stack. The preset tobacco leaf contour-location database may include, but is not limited to, at least three tobacco leaf locations: top filler, middle filler, and bottom filler, as well as sample tobacco leaf contour features corresponding to each of these locations. The preset tobacco leaf contour-location database may be manually derived based on statistical analysis of historical contour features corresponding to various tobacco leaf locations.

[0059] Next, after determining the sample tobacco leaf contour feature with the highest similarity corresponding to each group of cigar tobacco leaf stacks in the preset tobacco leaf contour-position database, the control terminal may use the cigar position corresponding to the sample tobacco leaf contour feature with the highest similarity in the preset tobacco leaf contour-position database as the cigar position of the corresponding cigar tobacco leaf stack. It is understood that when the similarities between each sample tobacco leaf contour in the preset tobacco leaf contour-position database and the tobacco leaf contour feature corresponding to each group of cigar tobacco leaf stacks are all within the same similarity range, or when the highest similarity is below a preset similarity threshold, it indicates that the tobacco leaf contour feature recognition of the corresponding cigar tobacco leaf stack is abnormal. The industrial camera may be controlled to adjust its shooting angle to retake the image to be processed containing two adjacent groups of cigar tobacco leaf stacks from another angle until the cigar position is determined.

[0060] Step 104: When the filler parts of all the cigar tobacco leaf stacks are consistent, each group of cigar tobacco leaf stacks is turned over at least twice based on the stack core temperature threshold corresponding to the filler parts of the cigar tobacco leaf stacks.

[0061] Specifically, after identifying the filler portion of each group of cigar tobacco stacks, the control terminal can also determine whether the filler portions of two adjacent groups of cigar tobacco stacks in the image to be processed are consistent. It can be understood that when the filler portions of the two adjacent groups of cigar tobacco stacks are consistent, it indicates that the fermentation endpoint times corresponding to the two groups of cigar tobacco stacks can be consistent. In other words, data collection and analysis can be performed on any one of the two groups of cigar tobacco stacks to determine the fermentation endpoint times corresponding to the two groups of cigar tobacco stacks. When the filler portions of the two adjacent groups of cigar tobacco stacks are inconsistent, it indicates that the fermentation endpoint times corresponding to the two groups of cigar tobacco stacks are inconsistent. In other words, data collection and analysis can be performed on each of the two groups of cigar tobacco stacks to determine the fermentation endpoint times corresponding to the corresponding cigar tobacco stacks.

[0062] Furthermore, after determining that the core parts of all cigar tobacco leaf stacks are consistent, the control terminal can also determine the core temperature threshold corresponding to the core part of the cigar tobacco leaf stack based on the core part of the cigar tobacco leaf stack and the historical fermentation stack core temperature database, and use the core temperature threshold as the stack turning condition. When the core temperature of each group of cigar tobacco leaf stacks rises to the same as the core temperature threshold, the above-mentioned cigar tobacco leaf stacking device is controlled to turn the corresponding cigar tobacco leaf stack until the core temperature of the cigar tobacco leaf stack rises again to the same as the core temperature threshold, and the stack is turned again. The cigar tobacco leaf stacking device in the embodiment of the present application can, but is not limited to, turning each group of cigar tobacco leaf stacks separately, or turning two adjacent groups of cigar tobacco leaf stacks at the same time, and is not limited to this.

[0063] It can be understood that the historical fermentation pile core temperature database may include at least three citrus core parts, namely the top citrus core, the middle citrus core and the lower citrus core, as well as the historical fermentation pile core temperature limit values ​​corresponding to each citrus core part. For example, the fermentation pile core temperature limit value corresponding to the top citrus core is 50°C, the fermentation pile core temperature limit value corresponding to the middle citrus core is 45°C, and the fermentation pile core temperature limit value corresponding to the lower citrus core is 40°C.

[0064] Step 106: Obtain the first core moisture parameter corresponding to any group of cigar tobacco leaves stacks during each stack turning process, and obtain at least two groups of first temperature parameters of the corresponding cigar tobacco leaves stacks within a preset time period.

[0065] Specifically, when each group of cigar tobacco leaf stacks is turned over multiple times according to the stack core temperature threshold, the control terminal can also control the tobacco leaf moisture content detection device to perform moisture content detection on the tobacco leaves at the stack core of the cigar tobacco leaf stack after each turning process to obtain the corresponding first stack core moisture parameter. At the same time, the temperature detection device can also be controlled to collect multiple groups of temperature parameters at specified time intervals within a preset period. For example, the temperature parameters of the cigar tobacco leaf stack can be collected at 3 pm every day within a week (that is, a total of 7 groups of temperature parameters). Each group of temperature parameters can include but is not limited to the fermentation environment temperature at the current moment and the tobacco leaf stack core temperature at the stack core of the cigar tobacco leaf stack.

[0066] It can be understood that since the filler areas of the two groups of cigar tobacco leaves are consistent, the turning times of the two groups of cigar tobacco leaves during fermentation can be kept consistent. In other words, all first core moisture parameters and first temperature parameters collected from any one group of cigar tobacco leaves can represent all first core moisture parameters and first temperature parameters corresponding to the two groups of cigar tobacco leaves.

[0067] Step 108: Determine the fermentation endpoint time of all the cigar tobacco leaves in the stack based on the filler portion of the cigar tobacco leaves, all the first core moisture parameters, and all the first temperature parameters.

[0068] Specifically, after collecting at least two first pile core moisture parameters corresponding to any group of cigar tobacco leaves and at least two groups of first temperature parameters within a preset time period, the control terminal can analyze and process the at least two first pile core moisture parameters and at least two groups of first temperature parameters according to the core position of the cigar tobacco leaves, for example but not limited to, after collecting n first pile core moisture parameters and m groups of first temperature parameters, by analyzing and processing the n first pile core moisture parameters and m groups of first temperature parameters, and determining that the current moment is not all cigar leaves. At the fermentation endpoint of the cigar tobacco pile, the n+1th moisture parameter of the first pile core and the m+1th group of first temperature parameters can be continuously collected. After the n+1th moisture parameter of the first pile core and the m+1th group of first temperature parameters are collected, the n+1th moisture parameter of the first pile core and the m+1th group of first temperature parameters are analyzed and processed to again determine whether the current moment is the fermentation endpoint of all cigar tobacco piles, until a certain moment is determined to be the fermentation endpoint of all cigar tobacco piles, and the fermentation process can be stopped in a timely manner for all cigar tobacco piles. Here, n and m are both positive integers greater than or equal to 2.

[0069] As another option of the embodiment of the present application, each set of first temperature parameters includes a fermentation environment temperature and a cellophane core temperature corresponding to the same moment;

[0070] The fermentation endpoint of all cigar tobacco stacks is determined based on the filler position of the cigar tobacco stack, all first stack core moisture parameters, and all first temperature parameters, including:

[0071] Determining a corresponding preset temperature range, a preset core moisture range, and an initial core moisture parameter based on the core portion of the cigar tobacco leaf stack, and calculating a first difference between the fermentation environment temperature and the core temperature of the cigar tobacco leaf stack in each set of first temperature parameters;

[0072] Performing a summation process on the first differences corresponding to all the first temperature parameters, and when detecting that the summation result is within a preset temperature range, calculating a second difference between the minimum first pile core moisture parameter and the initial pile core moisture parameter;

[0073] When it is detected that the second difference is in the preset stack core moisture range, the current moment is used as the fermentation end moment of all cigar tobacco leaf stacks, and the fermentation process of all cigar tobacco leaf stacks is stopped.

[0074] Specifically, when the fermentation endpoint time of all cigar tobacco stacks is obtained, the control terminal can first determine the corresponding preset temperature range, preset stack core moisture range and initial stack core moisture parameter according to the core part of the cigar tobacco stack. For example, but not limited to, when the core part of the cigar tobacco stack is the top core, the corresponding preset temperature range can be 390-410°C (or the preset temperature is 400°C), the preset stack core moisture range can be 5-9% (or the preset stack core moisture content is 7%), and the initial stack core moisture parameter can be 32%; when the cigar tobacco stack is the top core, the preset temperature range can be 390-410°C (or the preset temperature is 400°C), the preset stack core moisture range can be 5-9% (or the preset stack core moisture content is 7%), and the initial stack core moisture parameter can be 32%; When the filler portion of the cigar tobacco pile is the middle filler, the corresponding preset temperature range can be 290-310°C (or the preset temperature is 300°C), the preset core moisture range can be 5-9% (or the preset core moisture content is 7%), and the initial core moisture parameter can be 30%. When the filler portion of the cigar tobacco pile is the lower filler, the corresponding preset temperature range can be 230-270°C (or the preset temperature is 250°C), the preset core moisture range can be 6-10% (or the preset core moisture content is 8%), and the initial core moisture parameter can be 28%. It should be noted that the preset temperature range, preset core moisture range, and initial core moisture parameter corresponding to each filler portion can be manually determined by combining the historical temperature and moisture data recorded for the corresponding filler portion during the fermentation process to ensure the authenticity and validity of the data.

[0075] Next, after determining the preset temperature range, preset core moisture range, and initial core moisture parameter corresponding to the filler portion of the cigar tobacco stack, the control terminal may further calculate a first difference between the fermentation environment temperature and the core temperature of the cigar tobacco stack among all currently collected first temperature parameters (in this embodiment of the present application, calculation processing may be performed when two sets of first temperature parameters are collected to ensure real-time data processing), and sum all of the first differences to obtain a corresponding summation result. It is understood that when this summation result is within the preset temperature range (or is consistent with the preset temperature), it indicates that the cigar tobacco stack currently meets the temperature requirements during the fermentation process. The control terminal may then calculate a second difference between the smallest first core moisture parameter among all currently collected first core moisture parameters and the initial core moisture parameter, to further determine whether the cigar tobacco stack currently meets the moisture requirements during the fermentation process based on this second difference. Here, when the summation processing result is not within the preset temperature range (or is inconsistent with the preset temperature), it indicates that the cigar tobacco leaf stack currently does not meet the temperature requirements of the fermentation process, and the control terminal can, but is not limited to, continue to collect the next set of temperature parameters. In the process of collecting the next set of temperature parameters, the corresponding first stack core moisture parameters can also be collected during the stack turning process. After the next set of temperature parameters are collected when the total number of stack turning processes does not exceed the preset number threshold, the first difference between the fermentation environment temperature and the cigar core stack core temperature of all the currently collected first temperature parameters and the corresponding summation processing results are calculated again until a summation processing result is within the preset temperature range (or is consistent with the preset temperature).

[0076] Then, when it is detected that the second difference is within the preset stack core moisture range (or is consistent with the preset stack core moisture content), it indicates that the cigar tobacco leaf stack currently meets both the temperature requirements and the moisture content requirements during the fermentation process. The current moment can then be used as the fermentation endpoint of all cigar tobacco leaf stacks. That is, after it is detected that the second difference is within the preset stack core moisture range, the fermentation process of all cigar tobacco leaf stacks can be stopped, so as to effectively ensure the quality and efficiency of cigar tobacco leaf fermentation.

[0077] As another optional embodiment of the present application, after summing the first differences corresponding to all first temperature parameters, the method further includes:

[0078] When it is detected that the summation result is not within the preset temperature range, the total number of stacking processes is determined;

[0079] When the total number of stack turning processes exceeds a preset number threshold, a stack core moisture change curve is generated based on all first stack core moisture parameters and the collection time corresponding to each first stack core moisture parameter;

[0080] When it is detected that all slopes corresponding to the pile core moisture content change curve are within the preset slope range, the estimated time corresponding to the preset pile core moisture content range is determined according to the pile core moisture content change curve, and the estimated time is used as the fermentation end time of all cigar tobacco leaf piles.

[0081] Specifically, when it is detected that the summation result is not within the preset temperature range (or is inconsistent with the preset temperature), it indicates that the cigar tobacco stack has not yet met the temperature requirements for the fermentation process, and the total number of stack turning processes to that point can also be calculated. It is understood that when the total number of stack turning processes of the cigar tobacco stack exceeds a preset number threshold, if the corresponding summation result is still not within the preset temperature range (or is inconsistent with the preset temperature), it indicates that the cigar tobacco stack may be fermenting slowly or abnormally.

[0082] Next, in order to determine whether the cigar tobacco leaf stack is currently experiencing a slow fermentation phenomenon or fermentation abnormality, the control terminal can, but is not limited to, generating a stack core moisture change curve based on all the first stack core moisture parameters currently collected and the collection time corresponding to each first stack core moisture parameter. The stack core moisture change curve can be understood as a smooth curve composed of multiple coordinate points, the horizontal coordinate of each coordinate point can correspond to the collection time, and the vertical coordinate can correspond to the first stack core moisture parameter corresponding to the collection time, and the slope between every two adjacent coordinate points is calculated. When it is detected that all slopes are within a preset slope range, it indicates that the cigar tobacco leaf stack is currently experiencing a slow fermentation phenomenon (that is, the stack core moisture parameter continues to decrease). Furthermore, all coordinate points on the stack core moisture change curve can be fitted, but is not limited to, to obtain a corresponding fitting curve function, and the minimum stack core moisture content, the middle stack core moisture content, or the maximum stack core moisture content within the preset stack core moisture range is substituted into the fitting curve function to calculate the corresponding estimated time. Here, when the fermentation process reaches the estimated moment, it indicates that the fermentation of all cigar tobacco leaf stacks has been completed, and the fermentation process of all cigar tobacco leaf stacks can be stopped.

[0083] It can be understood that when it is detected that any slope is not within the preset slope range, it indicates that the cigar tobacco leaf stack is currently fermenting abnormally, and the fermentation process of all cigar tobacco leaf stacks can be stopped in time, and manual inspection and processing of all cigar tobacco leaf stacks can be notified to avoid affecting the quality of the cigar tobacco leaf stacks.

[0084] As another optional embodiment of the present application, after identifying the filler portion of each group of cigar tobacco leaves from the image to be processed, the method further includes:

[0085] When the filler positions of all cigar tobacco leaf stacks are inconsistent, the corresponding cigar tobacco leaf stacks are turned over at least twice based on the stack core temperature threshold corresponding to the filler position of each group of cigar tobacco leaf stacks;

[0086] Obtaining a second core moisture parameter of each group of cigar tobacco leaves stacked during each stack turning process, and obtaining at least two groups of second temperature parameters within a preset time period;

[0087] Determining a correction parameter for the corresponding cigar tobacco stack based on preset weights corresponding to all filler parts, and performing correction processing on each corresponding second temperature parameter based on the correction parameter to obtain a third temperature parameter;

[0088] The corresponding fermentation endpoint time is determined based on the core part corresponding to each group of cigar tobacco leaf stacks, all moisture parameters of the second core stacks, and all third temperature parameters.

[0089] Specifically, when the filler locations of all cigar stacks are inconsistent, it indicates that the fermentation endpoint times corresponding to the two groups of cigar stacks are inconsistent. This means that data collection and analysis processing are required for each group of cigar stacks to determine the fermentation endpoint time corresponding to the corresponding cigar stack. Furthermore, the times corresponding to the stack turning process for each group of cigar stacks are inconsistent (each group of cigar stacks needs to be turned separately). It is understood that the methods for obtaining the second core moisture parameter corresponding to each group of cigar stacks during each turning process, as well as obtaining at least two sets of second temperature parameters within a preset time period, can be referred to in one or more of the above embodiments and will not be further elaborated here.

[0090] Next, to ensure the accuracy of the temperature parameters, correction parameters for the corresponding cigar tobacco leaf stacks may be determined based on preset weights corresponding to all filler parts. For example, but not limited to, taking the two groups of filler parts, namely, the top filler and the middle filler, the preset weight corresponding to the top filler may be set to 1.1, and the preset weight corresponding to the middle filler may be set to 1.2. Then, the correction parameter for the cigar tobacco leaf stack corresponding to the top filler may be a ratio between 1.2 and 1.1 (i.e., greater than 1), thereby reducing the influence of the stack core temperature threshold (lower temperature) corresponding to the middle filler on the temperature parameters collected from the top filler. Furthermore, the correction parameter for the cigar tobacco leaf stack corresponding to the middle filler may be a ratio between 1.1 and 1.2 (i.e., less than 1), thereby reducing the influence of the stack core temperature threshold (higher temperature) corresponding to the top filler on the temperature parameters collected from the middle filler.

[0091] Next, after determining the correction parameter for each group of cigar tobacco leaves, the control terminal may also, but is not limited to, multiply the correction parameter by the corresponding second temperature parameter, the core temperature of the cigar stack, and use the processed core temperature and the collected fermentation environment temperature as the third temperature parameter. The control terminal then determines the corresponding fermentation endpoint time based on the corresponding core portion of each group of cigar tobacco leaves, all second core moisture parameters, and all third temperature parameters. The method for determining the fermentation endpoint time for each group of cigar tobacco leaves can also be referred to in one or more of the above embodiments and will not be further elaborated.

[0092] It should be noted that the use of changes in the temperature of the tobacco leaf pile core and the moisture content of the tobacco leaves during the fermentation process to judge the end point of tobacco leaf fermentation can greatly ensure the objectivity, accuracy and timeliness of the determination of the end point of tobacco leaf fermentation, compared with the existing fermentation end point judgment which mainly relies on experience technology. Compared with manual smelling of tobacco leaves and sensory quality evaluation, the accumulated temperature and precipitation determination method is the product of the combination of a large amount of fermentation data monitoring, human experience judgment and sensory evaluation. It uses intuitive and quantifiable digital indicators as a reference, which can enhance the objectivity, accuracy and timeliness of the determination of the fermentation end point, reduce the workload of manual smelling and evaluation, and reduce the risk of occupational diseases.
