[0002] In the tobacco industry, the fermentation quality of tobacco leaves is influenced by many factors, among which the intrinsic quality of the tobacco leaves and the fermentation environment play a decisive role in the fermentation process and effect. The intrinsic quality of tobacco leaves mainly depends on the tobacco-producing region, variety, part of the plant, maturity, moisture content, and the degree of fermentation already achieved. The fermentation environment mainly depends on air temperature, relative humidity, and airflow. Current methods for controlling the overall quality of tobacco leaf fermentation primarily rely on manual control. Due to the inherent limitations of manual control, it is impossible to automatically regulate the moisture content of the tobacco leaves and the fermentation environment. Furthermore, frequent personnel movement during control can significantly impact environmental factors in the fermentation chamber, and irritating gases such as ammonia pose safety hazards to control personnel. Therefore, a method capable of intelligent control based on the actual conditions inside the fermentation chamber and production needs is needed. Summary of the Invention

[0032] In addition, it should be noted that, Figure 1 The system shown is merely one example of the system provided in this disclosure. In practical applications, other systems may also be included, such as more terminals.

[0033] In the embodiments described in this specification, the terminal 10 and the server 20 can be directly or indirectly connected through wired or wireless communication, and this disclosure does not impose any restrictions.

[0034] Please refer to the following. Figure 2 , Figure 2 The diagram shows an overall flowchart of a method for targeted regulation of tobacco quality provided in an embodiment of this specification. This method can be used in server 20.

[0035] like Figure 2 As shown, this method for targeted regulation of tobacco leaf quality may include at least the following steps:

[0036] Step 201: Obtain various test data from the tobacco fermentation chamber.

[0037] The detection data includes temperature and humidity data, ammonia concentration data, and dryness data of each tobacco leaf stack, which is placed in the tobacco leaf fermentation chamber.

[0038] In the embodiments described in this specification, tobacco leaves are mainly placed in a tobacco fermentation chamber in the form of stacks during storage and fermentation. The fermentation quality of the tobacco leaves is mainly determined by the temperature and humidity of the fermentation environment and the dryness of the tobacco leaves themselves. Therefore, in order to control the quality of the tobacco leaves in the fermentation chamber, it is necessary to first obtain various detection data inside the tobacco fermentation chamber. These detection data may include temperature and humidity data of the tobacco fermentation chamber, ammonia concentration data, and dryness data of each tobacco leaf stack.

[0039] The primary reason for obtaining ammonia concentration data is that excessively high indoor ammonia concentrations can affect the health of production personnel, and ammonia, when mixed with air within a certain concentration range, may explode upon encountering an ignition source or high temperature. Furthermore, ammonia is corrosive to many materials; high concentrations can cause corrosion of equipment, pipes, and instruments, thereby affecting the normal operation and lifespan of production equipment.

[0040] In one possible implementation, the acquisition of various detection data from the tobacco fermentation chamber, including temperature and humidity data, ammonia concentration data, and dryness data of each tobacco stack, includes:

[0041] Temperature and humidity data of the tobacco fermentation chamber are obtained based on temperature and humidity sensors;

[0042] Ammonia concentration data in the tobacco fermentation chamber is obtained based on an ammonia sensor.

[0043] The dryness data of each tobacco stack is obtained based on each image sensor. Each image sensor is placed directly above each tobacco stack, and the connection diagram of each image sensor corresponding to each tobacco stack is the circumscribed quadrilateral of the tobacco stack in the horizontal plane.

[0044] In the embodiments of this specification, when acquiring various detection data in the tobacco fermentation chamber, the temperature and humidity sensor and the ammonia sensor can be placed at the center of the tobacco fermentation chamber to make their detection data more representative of the actual environment of the entire tobacco fermentation chamber. The temperature and humidity data are acquired by the temperature and humidity sensor located inside the tobacco fermentation chamber, and the ammonia concentration data is acquired by the ammonia sensor located inside the tobacco fermentation chamber. When acquiring the dryness data of each tobacco stack, an image sensor can be placed at each of the four corners directly above each tobacco stack. The connected image of the four image sensors includes a top view of each tobacco stack, i.e., the circumscribed quadrilateral of each tobacco stack in the horizontal plane. Images of the entire tobacco stack are acquired using the four image sensors. Then, the four images are calibrated and fused to obtain a standard complete image of the entire tobacco stack. Furthermore, the standard complete image obtained by fusion is preprocessed, such as denoising, contrast enhancement, cropping, and scaling, to improve the accuracy of subsequent analysis. Next, image processing algorithms are used to analyze the image data and extract features related to tobacco leaf dryness, including color analysis, texture analysis, and shape analysis. Finally, the obtained image features are converted into dryness data.

[0045] Step 202: Determine the air intake parameters of the air conditioner based on the temperature and humidity data, determine the cooperative working mode of the circulating fan and the purification equipment based on the ammonia concentration data, and determine the humidification scheme of the tobacco stack based on the dryness data.

[0046] In the embodiments of this specification, after acquiring the temperature and humidity data, ammonia concentration data, and dryness data of each tobacco stack inside the tobacco fermentation chamber, it can be determined whether the temperature and humidity data meet the requirements to adjust the air conditioning intake parameters, thereby changing the temperature and humidity inside the tobacco fermentation chamber. The acquired ammonia concentration data can also be used to determine whether the ammonia concentration inside the tobacco fermentation chamber exceeds the standard, and to determine the cooperative working mode of the circulating fan and purification equipment for efficient and energy-saving purification of indoor ammonia. Simultaneously, after acquiring the dryness data corresponding to each tobacco stack, it is also used to determine whether each tobacco stack needs humidification, and to determine the specific humidification scheme for each tobacco stack.

[0047] In the conventional tobacco fermentation chamber equipment configuration, the air conditioner and circulating fan are respectively installed on the two side walls of the tobacco fermentation chamber, and the purification equipment is installed inside the tobacco fermentation chamber.

[0048] In one possible implementation, determining the air conditioning intake parameters based on the temperature and humidity data includes:

[0049] A simulation model of the tobacco fermentation chamber was determined based on its internal structure.

[0050] The temperature and humidity data are input into the simulation model to obtain the temperature and humidity flow field corresponding to the temperature and humidity data;

[0051] The air conditioning intake parameters corresponding to the temperature and humidity flow field are determined based on a preset air conditioning parameter database.

[0052] In the embodiments of this specification, when determining whether the acquired internal temperature and humidity data of the fermentation chamber requires adjustment of the air conditioning intake parameters, a simulation model of the tobacco fermentation chamber can be determined first. A typical tobacco fermentation chamber configuration includes one air conditioner, four circulating fans, one purification device, a temperature and humidity sensor, an ammonia concentration sensor, six tobacco stacks, and their corresponding image sensors. After determining the dimensional parameters of all equipment in the fermentation chamber, a simulation model of the tobacco fermentation chamber is constructed, and the simulation model is meshed. Next, the acquired temperature and humidity data is input into the tobacco fermentation chamber simulation model to obtain its corresponding temperature and humidity flow field. Finally, the temperature and humidity flow field is matched with a preset fermentation standard to obtain its corresponding air conditioning intake parameters.

[0053] Among them, the preset fermentation standard can be established by statistically analyzing long-term historical data of tobacco fermentation, and a corresponding relationship can be established by adjusting the air conditioning intake parameters to achieve the optimal fermentation temperature and humidity under a given temperature, humidity and flow field.

[0054] In one possible implementation, determining the cooperative operating mode of the circulating fan and purification equipment based on the ammonia concentration data includes:

[0055] The ammonia concentration data is compared with a preset ammonia concentration threshold to obtain a first comparison result;

[0056] When the first comparison result indicates that the ammonia concentration data exceeds the ammonia concentration threshold, the cooperative working mode of the circulating fan and the purification equipment is determined to be that the circulating fan and the purification equipment work simultaneously.

[0057] When the first comparison result is that the ammonia concentration data exceeds half of the ammonia concentration threshold but does not exceed the ammonia concentration threshold, the cooperative working mode of the circulating fan and the purification equipment is determined to be that the circulating fan is working and the purification equipment is not working.

[0058] When the first comparison result shows that the ammonia concentration data does not exceed half of the ammonia concentration threshold, the cooperative working mode of the circulating fan and the purification equipment is determined to be that the purification equipment is working and the circulating fan is not working.

[0059] In the embodiments of this specification, a single purification device is typically installed in a conventional tobacco fermentation chamber, while multiple circulating fans can be installed. When dealing with long-term low-concentration ammonia, the purification device provides the best performance under the same energy consumption standard, while when dealing with higher-concentration ammonia, the circulating fans perform better under the same energy consumption standard. After obtaining ammonia concentration data through an ammonia sensor, to efficiently and energy-savingly purify the ammonia in the tobacco fermentation chamber, the ammonia concentration data can be compared with a preset ammonia concentration threshold to obtain a first comparison result. When the first comparison result indicates that the detected ammonia concentration exceeds the preset ammonia concentration threshold, it indicates that the ammonia concentration is severely excessive, and both the circulating fans and the purification device need to be turned on simultaneously to ensure that the ammonia in the chamber can be removed as quickly as possible. When the first comparison result indicates that the detected ammonia concentration exceeds half of the preset ammonia concentration threshold but does not exceed the threshold, it indicates that the ammonia concentration is still high, but only the circulating fans need to be turned on while the purification device is turned off, thereby saving some energy. When the first comparison result indicates that the detected ammonia concentration does not exceed half of the preset ammonia concentration threshold, it indicates that the ammonia concentration is low. In this case, it is sufficient to turn on the purification equipment and turn off the circulating fan to achieve energy saving.

[0060] In one possible implementation, determining the humidification scheme for the tobacco stack based on the dryness data includes:

[0061] Each of the aforementioned dryness data is compared with a preset dryness threshold to obtain a second comparison result;

[0062] When the second comparison result indicates that the dryness data exceeds the dryness threshold, the tobacco stack corresponding to the dryness data at this time is marked as a stack to be humidified.

[0063] All the stacks to be humidified are statistically analyzed, and the humidification scheme for the tobacco stacks is determined based on the dryness data corresponding to each stack.

[0064] In the embodiments of this specification, during the fermentation process of tobacco leaves in the fermentation chamber, humidification treatment is required based on the real-time dryness of the tobacco leaves to ensure optimal fermentation quality. After acquiring dryness data through the image sensor corresponding to each tobacco leaf stack, the dryness data of each tobacco leaf stack is compared with a preset dryness threshold to obtain a second comparison result. When the second comparison result is positive, it indicates that the corresponding dryness data is greater than the preset dryness threshold, meaning that the tobacco leaf stack is already dry and needs humidification treatment; this tobacco leaf stack can be marked as a stack to be humidified. Similarly, the dryness status of all tobacco leaf stacks in the tobacco fermentation chamber is judged, and all stacks to be humidified are counted. Based on the dryness data of each stack to be humidified, a humidification scheme for the overall tobacco leaf stack is determined. Specifically, the tobacco leaf stacks can be sorted by dryness, and the corresponding humidification scheme is set to prioritize humidification of tobacco leaf stacks with higher dryness.

[0065] In one possible implementation, determining the humidification scheme for the tobacco stacks based on the dryness data corresponding to each of the stacks to be humidified includes:

[0066] Collect the dryness data corresponding to each of the aforementioned stacks to be humidified;

[0067] Sort the dryness data from highest to lowest dryness to obtain the dryness order;

[0068] The dryness order is weighted based on the relative distance between each tobacco stack to determine the humidification order of each stack to be humidified, and the humidification scheme of the tobacco stack is determined based on the humidification order. The relative distance is the distance between each tobacco stack and the initial position of the steam humidifier.

[0069] In the embodiments of this specification, when determining the humidification scheme for tobacco stacks, the dryness data corresponding to each stack to be humidified can be collected first. Then, the dryness data can be sorted from high to low to obtain a dryness order. The higher the dryness order, the higher the humidification requirement of the tobacco stack. Furthermore, to improve the overall humidification efficiency, the distance between each tobacco stack and the initial position of the steam humidifier needs to be considered. Generally, the steam humidifier is set at a fixed initial position in the tobacco fermentation chamber when in standby mode. Therefore, after obtaining the dryness order, the distance between each tobacco stack to be humidified and the initial position of the steam humidifier can be converted into a weighting coefficient. Based on the obtained weighting coefficient, the dryness order can be converted into a weighting coefficient to obtain the humidification order of the stacks to be humidified. Finally, the final humidification scheme is determined based on this humidification order to ensure that the entire humidification scheme can simultaneously take into account both dryness and distance factors, thereby improving the overall humidification efficiency.

[0070] Step 203: Integrate the air conditioning intake parameters, working mode and humidification scheme to obtain the control scheme, and control the tobacco fermentation chamber based on the control scheme.

[0071] In the embodiments of this specification, after obtaining the air conditioning intake parameters, the working mode and the humidification scheme, the schemes are integrated to obtain the final control scheme corresponding to the tobacco fermentation chamber. Based on the control scheme, the air conditioning, purification equipment, circulating fan and steam humidifier in the tobacco fermentation chamber are controlled to automatically regulate the tobacco fermentation chamber.

[0072] In one possible implementation, the method further includes:

[0073] Determine the type of tobacco leaves in each of the aforementioned tobacco leaf stacks;

[0074] Based on the tobacco leaf type, the spraying device sprays nutrient solution onto each of the tobacco leaf stacks. The nutrient solution includes dominant bacteria, biological enzymes, and beneficial bacteria.

[0075] In the embodiments of this specification, during the tobacco fermentation process, a nutrient solution can be sprayed onto the surface of the tobacco leaves. This nutrient solution promotes biochemical metabolism within the tobacco leaves, achieving targeted acceleration of the fermentation process, harmonization of chemical components, enhancement of aroma and quality, and reduction of harshness and harmful substances, thereby improving the quality of the tobacco leaves. Since the optimal type of nutrient solution for each type of tobacco leaf is different, the size, texture, and color features of the tobacco leaves can be extracted first based on an image sensor to determine the type of tobacco leaves in each stack. Then, the optimal nutrient solution corresponding to the type of tobacco leaf is sprayed onto that stack. The types of nutrient solutions include dominant bacteria, biological enzymes, and beneficial bacteria.
