[0002] Flue-curing tobacco barns are crucial facilities in the tobacco industry. They are specifically designed to transform freshly harvested tobacco leaves into finished tobacco leaves with uniform color and rich aroma through a specific temperature and humidity control process. These barns typically utilize advanced temperature control technology and ventilation systems to ensure uniform heating of the leaves during the curing process while maintaining optimal humidity conditions to promote the transformation of the leaves' internal chemical components and achieve the desired taste and aroma.

[0003] Structurally, a tobacco curing barn typically features well-insulated walls and roofing to minimize heat loss and maintain a stable internal environment. While the interior space varies depending on the scale of the curing operation, it is typically equipped with multiple layers of racks for hanging or laying tobacco leaves, ensuring efficient use of space and facilitating leaf management and turnover.

[0004] However, during the baking process, the temperature needs to be continuously raised and lowered, which results in energy waste. Summary of the Invention

[0034] Compared with the prior art, the advantages of the present invention are:

[0035] By configuring multiple rooms with independent, single-temperature control systems, we achieve precise and simple temperature control. This layout not only greatly simplifies the complexity of temperature management, but also ensures that each room can be quickly adjusted to the desired temperature conditions without tedious waiting and complicated adjustment processes.

[0036] This process makes tobacco storage and handling extremely efficient: tobacco can be quickly transferred from one room, where the temperature and humidity are set to the right level, to another room with the same ideal conditions, eliminating the need for a slow change of the entire room's environment. This instant transfer capability significantly reduces waiting time, ensures continuous tobacco processing, and perfectly matches the efficient rhythm of the assembly line.

[0037] Furthermore, each room is equipped with advanced drying ovens, which, based on the already precisely controlled temperatures in their respective rooms, further finely and precisely regulate the temperature and humidity of the tobacco. This dual control mechanism not only ensures even and stable heating of the tobacco during the drying process, but also promotes the perfect transformation of the tobacco's internal chemical components, significantly improving the quality of the final product and making the tobacco produced more superior in both taste and aroma.

[0043] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0044] This invention allows multiple rooms to be controlled with a single temperature, simplifying control. Tobacco can be transferred directly from one room to another without waiting for the temperature and humidity of the entire room to change, resulting in rapid, streamlined operation. The drying ovens further finely control the temperature in each room, resulting in higher-quality tobacco.

[0045] In order to better understand the above technical solution, a detailed description is given below in conjunction with specific implementation methods.

[0046] like Figure 1 , Figure 2 as well as Figure 3 As shown, a tobacco leaf baking monitoring method comprises:

[0047] S1, the tobacco leaves are sorted and placed on the baking net 11, and the baking net 11 is placed into the baking oven 1 according to the classification, and the standby charging mode of the baking oven is activated and charging is started.

[0048] First, workers carefully select the tobacco leaves according to established classification criteria, placing them neatly onto specialized baking nets. This step is crucial, as it directly impacts the uniformity of the tobacco leaves' heating during the subsequent baking process, as well as the quality of the final product. Once sorted, each baking net holds the same type of tobacco, ensuring optimal treatment tailored to its characteristics during the baking process.

[0049] Then, according to the classification results, the staff placed the baking nets loaded with tobacco leaves one by one and in an orderly manner into the pre-prepared baking oven. The baking oven is designed with customized brackets and positions for the baking nets to ensure that the baking nets are firmly placed and that there is enough space for sufficient heat exchange during the baking process.

[0050] After all the baking nets are properly positioned, the staff activates the oven's standby charging mode via the control panel. This mode preheats the oven to a suitable temperature range and reserves sufficient energy for the subsequent baking process. The oven's intelligent control system automatically detects its current status and gradually increases the temperature according to a pre-set schedule. Simultaneously, the internal heating elements and circulation system enter a standby state, ensuring that the oven environment is optimal before the actual baking begins.

[0051] S2, placing the oven 1 into the preheating room 2 and activating the preheating mode of the oven. The preheating room 2 is used to provide the minimum temperature required for preheating.

[0052] Following step S1, to ensure a smooth curing process and maximize curing efficiency and tobacco quality, the oven, loaded with tobacco leaves and in standby charging mode, must be carefully and securely moved into the preheating room. Preheating room 2 is a separate space designed specifically for oven preheating. Its internal environment is carefully controlled to provide the minimum temperature required for oven preheating.

[0053] In the preheating room, staff will once again check the oven to ensure that the heat and humidity levels are normal, which could affect the baking results. Once confirmed, they will activate the oven's preheating mode through the control system within the preheating room. Once this mode is activated, the oven's internal heating system will gradually increase its temperature. Simultaneously, the preheating room's constant temperature system will also begin to operate, providing a stable and suitable external temperature environment for the oven, accelerating the process of reaching the optimal baking temperature inside the oven.

[0054] The duration of preheating mode varies depending on factors such as the oven model, size, and current ambient temperature, but it generally stays within a reasonable range to ensure energy is not wasted and the oven reaches optimal operating condition before the actual baking begins. During this process, the preheating room not only provides an ideal preheating environment for the oven, but also, through its internal temperature and humidity control system, effectively prevents the external environment from affecting the internal environment of the oven, laying a solid foundation for subsequent baking operations.

[0055] S3, after the oven is started in preheating mode, the oven internal preheating parameters are monitored and a monitoring video is uploaded to the monitoring system. The preheating parameters include dry-bulb temperature, wet-bulb temperature, humidity and preheating time.

[0056] With the oven's preheat mode officially activated, a crucial monitoring phase begins. The goal here is to ensure the oven preheats smoothly according to the pre-set schedule, achieving optimal baking conditions. Therefore, immediately after preheat mode is activated, we must closely monitor the oven's preheating parameters and upload this data in real time to the central monitoring system.

[0057] Specifically, monitored preheating parameters include, but are not limited to, dry-bulb temperature, wet-bulb temperature, humidity, and preheating time. Dry-bulb temperature refers to the actual temperature of the air inside the oven, directly reflecting the heat level during the baking process. Wet-bulb temperature, on the other hand, is a temperature reading that takes into account air humidity and is crucial for understanding the evaporation state of moisture in the baking environment. Humidity is directly related to changes in the moisture content of the tobacco leaves during the baking process, which has a direct impact on the taste and quality of the final product. Preheating time refers to the time it takes for the oven to reach the preset baking temperature after starting the preheating mode. This parameter is important for optimizing the baking process and saving energy.

[0058] To monitor these parameters in real time, we employ advanced sensor technology and high-definition video surveillance equipment. Sensors precisely measure the dry-bulb temperature, wet-bulb temperature, and humidity inside the oven, while high-definition cameras capture changes within the oven, ensuring we can intuitively identify any anomalies during the preheating process. The data collected by these devices and sensors is uploaded to a central monitoring system in real time via wireless or wired connections for remote monitoring and analysis.

[0059] During the monitoring process, if any preheating parameters deviate from the preset range or any abnormality is detected within the oven, the central monitoring system will immediately sound an alarm, prompting staff to intervene. The monitoring system also saves all uploaded surveillance video and data for subsequent analysis and improvement. This real-time monitoring and data analysis ensures that the oven is in optimal condition during the preheating phase, providing a solid foundation for subsequent baking operations.

[0060] S4, the monitoring system confirms the tobacco leaf baking condition through the monitoring video screen and adjusts the preheating parameters of the corresponding baking oven. The baking oven processes the gas entering the preheating room inside the baking oven according to the preheating parameters to achieve the preheating parameters.

[0061] The monitoring system's role becomes particularly prominent during the crucial preheating phase of the oven. It not only monitors preheating parameters within the oven, such as dry-bulb temperature, wet-bulb temperature, humidity, and preheating time, but also directly observes the tobacco leaves' curing progress through high-definition video. This step is crucial for ensuring high quality and consistency during the curing process.

[0062] The monitoring system's video function allows staff to view the tobacco leaves' condition inside the oven in real time, including color changes, moisture evaporation, and overall shape. This intuitive information, combined with preheating parameters, provides staff with a comprehensive analysis of the drying process. If the tobacco leaves' drying progress deviates from expectations, or if adverse conditions such as overheating or excessive humidity are present, staff can take immediate action by adjusting the corresponding oven's preheating parameters through the monitoring system.

[0063] The process of adjusting preheat parameters is highly automated. The monitoring system calculates the required preheat parameter values ​​based on observed baking conditions and preset baking standards, and transmits these adjustment instructions to the oven's control system. Upon receiving these instructions, the oven immediately processes the air entering the preheating chamber within the oven. This includes adjusting the air temperature, humidity, and flow rate to ensure that the air in the preheating chamber meets the new preheating parameters.

[0064] The preheating room's air handling system utilizes advanced temperature and humidity control technologies, enabling it to quickly and accurately respond to adjustments from the monitoring system. Through heating, humidification, and dehumidification, the air in the preheating room is optimally adjusted to match the new preheating parameters. This ensures a stable and optimal curing environment for the tobacco leaves during the preheating phase, ensuring high efficiency and quality during the curing process.

[0065] S5, continuously looping steps S3 and S4 until the preheating time reaches 0, activating the first transfer mode of the oven.

[0066] During the preparatory stage of tobacco curing, a carefully designed circulation mechanism ensures optimal oven curing conditions. The core of this mechanism is the continuous repetition of steps S3 and S4 until the preheating time reaches the critical point of 0. This process not only fine-tunes the oven's preheating state but also ensures a high degree of tobacco curing quality.

[0067] The cycle continues until the preheating time gradually approaches and eventually reaches 0. This moment marks the successful completion of the preheating phase and the official start of the baking process. When the preheating time reaches 0, the monitoring system automatically recognizes and activates the first transfer mode of the baking oven.

[0068] The first transfer mode is a critical step in the tobacco curing process, involving the smooth and efficient transfer of preheated tobacco leaves from the preheating room to the curing room. This mode, through precise mechanical control and temperature management, ensures that the tobacco leaves are not affected by any adverse factors during the transfer process, thus maintaining the continuity and stability of the curing process.

[0069] S6. After the first transfer of the baking oven is started, the gas entering the baking oven is pretreated according to the standard humidity control parameters, and after being transferred to the humidity control room with the transfer equipment, the humidity control mode of the baking oven is activated. The humidity control room is used to provide the minimum temperature and minimum humidity required for humidity control. The standard humidity control parameters are the baking parameters required for humidity control of the tobacco leaves of the corresponding classification, and the standard humidity control parameters include dry-bulb temperature, wet-bulb temperature, humidity and preheating time.

[0070] Once the oven's first transfer process has successfully commenced, the system automatically preconditions the incoming air according to pre-set standard humidity control parameters. This preconditioning optimizes air conditions to ensure optimal humidity control during the tobacco leaf curing process. The preconditioned air is then safely and efficiently transferred to a specially designed humidity control room, accompanied by the smooth operation of the transfer equipment. Once inside the humidity control room, the system immediately activates the oven's humidity control mode, tailored to meet specific curing requirements.

[0071] This humidity-controlled room plays a crucial role, providing a stable environment to ensure the drying ovens achieve the required minimum temperature and humidity levels. This environment is crucial for maintaining the ideal tobacco leaves during the drying process, helping to avoid degradation due to over-drying or insufficient humidity.

[0072] Furthermore, the standard humidity control parameters mentioned are not arbitrary, but rather are derived from in-depth research and experimental validation of different tobacco leaf types. These parameters precisely correspond to the specific humidity control conditions required for each tobacco leaf during the curing process, including but not limited to dry-bulb temperature (the actual ambient temperature), wet-bulb temperature (the temperature at which air nears saturation, a key indicator of ambient humidity), relative humidity, and preheating time. The preheating time is particularly important, ensuring that the oven and the tobacco leaves within are fully acclimated and reach the ideal preheating state before the formal curing phase begins, laying a solid foundation for the subsequent curing process.

[0073] S7, after the oven starts the humidity control mode, monitor the humidity control parameters inside the oven and upload the monitoring video to the monitoring system. The humidity control parameters include dry bulb temperature, wet bulb temperature, humidity and humidity control time.

[0074] After the oven successfully activates humidity control mode, it enters a highly monitored and regulated state. The system closely monitors various humidity control parameters within the oven, ensuring these key indicators remain within preset ideal ranges to guarantee tobacco curing quality and efficiency. These real-time monitored humidity control parameters specifically include dry-bulb temperature, wet-bulb temperature, humidity, and humidity control duration, each of which is crucial for determining curing results.

[0075] To provide comprehensive monitoring of the oven's internal environment, the system is equipped with high-definition cameras that record and upload real-time video to a central monitoring system. This not only allows operators to remotely monitor the baking process and promptly identify and address any anomalies, but also provides valuable visual data for subsequent baking analysis and quality traceability.

[0076] S8, the monitoring system confirms the tobacco leaf baking condition through the monitoring video screen, and adjusts the humidity control parameters of the corresponding baking oven. The baking oven processes the gas entering the humidity control room inside the baking oven according to the humidity control parameters to achieve the humidity control parameters.

[0077] The monitoring system leverages high-definition video technology to accurately monitor the tobacco leaves' curing progress in real time. The clear images displayed on the monitor screen allow operators to observe the leaves' changes at different stages of curing, including key indicators such as color, shape, and overall dryness. If the system detects that the tobacco leaves' curing progress or status are not meeting expectations, it immediately initiates intelligent adjustments.

[0078] Based on the actual tobacco leaf curing conditions monitored, the system automatically calculates and adjusts the corresponding oven humidity control parameters. These parameters, such as relative humidity, temperature, and air circulation rate, are optimized through precise calculations and accumulated experience, ensuring that the tobacco leaves are cured under optimal conditions for the best taste and quality.

[0079] After receiving the adjustment command, the intelligent humidity control system in the drying oven immediately goes into operation. It first measures the humidity and temperature of the air currently entering the humidity control room inside the drying oven. Then, based on the new humidity control parameters set by the system, it uses a series of advanced processing technologies such as humidification, dehumidification, heating or cooling to precisely adjust the air. This series of operations is designed to quickly and stably adjust the environmental conditions in the humidity control room to within the preset humidity control parameter range, thereby ensuring that the tobacco leaves are evenly and fully dehydrated during the drying process, ultimately producing high-quality tobacco products with bright color and rich aroma.

[0080] S9, continuously looping steps S7 and S8 until the humidity control time reaches 0, and then activating the second transfer mode of the oven.

[0081] The cycle mechanism plays a crucial role, ensuring the oven can continue to bake at optimal conditions until the predetermined humidity control time is reached. The core of this mechanism is the continuous cycle of steps S7 and S8 until the humidity control time gradually approaches and eventually reaches the critical point of zero.

[0082] During the cycle, step S7 involves continuous monitoring and adjustment of the oven's internal environment to ensure optimal baking conditions. This step involves not only meticulous control of dry-bulb temperature, wet-bulb temperature, and humidity, but also precise management of humidity control duration. Furthermore, through high-definition video monitoring, operators can observe the tobacco leaf's baking progress in real time, providing a visual basis for subsequent adjustments.

[0083] Next, step S8 makes necessary adjustments to the humidity control parameters based on the real-time monitoring data and video information provided by S7. The key to this step is that the system automatically calculates the required humidity control parameter values ​​based on the observed baking conditions and preset baking standards, and sends these adjustment instructions to the oven's control system. Upon receiving these instructions, the oven immediately processes the air entering the humidity control room to ensure that the air inside the room meets the new humidity control parameters.

[0084] The cycle continues until the humidity control time gradually decreases and eventually returns to zero. This moment marks the successful completion of the humidity control phase and is an important signal for the baking process to enter the next stage. When the humidity control time reaches 0, the system automatically recognizes and activates the oven's second transfer mode.

[0085] The second transfer mode is a critical step in the curing process. It involves the smooth and efficient transfer of moisture-controlled tobacco leaves from the humidity control room 3 to the next curing stage or cooling area. This mode ensures that the tobacco leaves are not adversely affected by any factors during transfer through precise mechanical control and temperature management, thus maintaining the continuity and stability of the curing process.

[0086] With the activation of the second transfer mode, the oven officially enters the next baking phase or prepares for cooling. During this phase, the oven continues to bake or cool the tobacco leaves according to the preset program and parameters. The monitoring system continues to play a vital role, monitoring various parameters and tobacco leaf status during the baking or cooling process in real time to ensure high quality and smooth operation.

[0087] S10, after the second transfer is started, the gas entering the baking oven is pretreated according to the standard withering parameters, and after being transferred to the withering room with the transfer equipment, the withering mode of the baking oven is activated. The withering room is used to provide the minimum temperature and minimum humidity required for moisture control. The standard withering parameters are the baking parameters required for withering of the classified tobacco leaves, and the standard withering parameters include dry-bulb temperature, wet-bulb temperature, humidity and preheating time.

[0088] After the oven's second transfer mode is activated, the system enters a more sophisticated and crucial processing stage: withering. The core of this stage is that the oven pre-conditions the air entering it according to preset standard withering parameters, ensuring that the air meets the withering conditions required for specific tobacco leaf categories when it is transported by the transfer equipment to the withering room.

[0089] First, standard withering parameters are carefully set based on the characteristics and requirements of different tobacco leaf types. These parameters cover multiple aspects, including dry-bulb temperature, wet-bulb temperature, humidity, and preheating time. These parameters are based on a deep understanding of tobacco leaf biology and in-depth research into the chemical mechanisms of moisture loss and enzymatic reactions within the tobacco leaf during the curing process. By precisely controlling these parameters, the withering process can be optimized to the greatest extent possible, achieving the best curing results.

[0090] During the S10 stage, preconditioning equipment within the oven conditions the incoming air according to standard withering parameters. This process may include heating, humidification, or dehumidification to ensure that the air's temperature, humidity, and other parameters precisely match the preset standard withering parameters before entering the withering chamber. This preconditioning step is crucial for improving withering efficiency and ensuring tobacco leaf quality.

[0091] The pre-treated air is then smoothly transported via the transfer equipment to the withering room. The withering room is designed to provide a stable and controlled environment that meets the minimum temperature and humidity requirements during the tobacco withering process. These requirements are set according to standard withering parameters to ensure that the withering process proceeds according to the predetermined rhythm and avoid poor quality of the tobacco leaves due to excessively fast or slow withering.

[0092] Inside withering chamber 4, with a continuous supply of gas and a stable environmental control, the oven's withering mode is officially activated. This mode meticulously cures the tobacco leaves within the chamber according to pre-set procedures and parameters. Precise control of temperature, humidity, and other parameters during the curing process, along with appropriate ventilation and exhaust design, ensures uniform heating and adequate moisture loss during the withering process, achieving the ideal withering effect.

[0093] S11, after the oven is started in the withering mode, the oven monitors the withering parameters inside the oven and uploads a monitoring video to the monitoring system. The withering parameters include dry-bulb temperature, wet-bulb temperature, humidity and withering time.

[0094] After the oven successfully activates withering mode, it enters a highly monitored and controlled state. The system closely monitors various withering parameters within the oven, ensuring these key indicators remain within preset ideal ranges to ensure the quality and efficiency of tobacco leaf withering. These real-time monitored withering parameters specifically include dry-bulb temperature, wet-bulb temperature, humidity, and withering duration, each of which is crucial for determining withering effectiveness.

[0095] Dry-bulb temperature, commonly referred to as ambient temperature, directly reflects the thermal conditions within the oven and has a direct impact on the rate and extent of tobacco leaf withering. Precisely controlling dry-bulb temperature ensures even heating during the withering process, preventing quality degradation caused by localized overheating or overcooling.

[0096] Wet-bulb temperature, measured by a specific humidity sensor, reflects the temperature at which water vapor in the air approaches saturation and is a key indicator for assessing ambient humidity. During the withering process, changes in wet-bulb temperature indirectly reflect the loss of moisture from the tobacco leaves, helping operators better monitor the withering process.

[0097] Humidity, another key parameter in the withering process, helps prevent tobacco leaves from losing their flavor and aroma due to overdrying, or from developing mold and spoilage due to excessive humidity. Proper humidity control ensures that the tobacco leaves maintain an appropriate moisture content during the withering process, laying a good foundation for subsequent baking operations.

[0098] Withering duration is a key parameter, preset based on the characteristics and needs of the tobacco leaves. It ensures that the leaves wither sufficiently and without over-withering, achieving optimal withering results. By precisely controlling the withering duration, we can avoid insufficient moisture loss from the leaves, or excessive flavor loss from over-withering.

[0099] To provide comprehensive monitoring of the oven's internal environment, the system is equipped with high-definition cameras that record and upload real-time video to a central monitoring system. This not only allows operators to remotely monitor the withering process and promptly identify and address any anomalies, but also provides valuable visual data for subsequent withering analysis and quality traceability.

[0100] S12, the monitoring system confirms the tobacco leaf baking condition through the monitoring video screen, and adjusts the withering parameters of the corresponding baking box. The baking box processes the gas entering the withering chamber inside the baking box according to the withering parameters to reach the withering parameters, and ends the baking after the withering time reaches 0.

[0101] Step S1 is a comprehensive preparation and preprocessing stage, which specifically includes the following detailed operation process:

[0102] S101 Tobacco Leaf Sorting and Arrangement: This step first requires staff to carefully sort the tobacco leaves according to their different properties. This classification is based on leaf section (such as the lower leaves, which are typically thinner and lighter in color; the middle leaves, which are more balanced and represent higher quality; and the upper leaves, which are thicker and darker in color); leaf maturity (different stages such as unripe, moderately ripe, and overripe, which influence the final taste); leaf thickness (which directly affects the baking time and temperature settings); and composition analysis (particularly the ratio of water to oil content, which is directly related to the dehydration rate and aroma retention during baking; aroma composition is also a key indicator of tobacco leaf quality). After classification, the various types of tobacco leaves are placed in an orderly manner on the baking racks in preparation for subsequent baking.

[0103] S102 Optimizing Curing Rack Arrangement: To improve curing efficiency and quality, tobacco leaves of the same category are further sorted on the curing racks based on moisture content. Specifically, leaves with higher moisture contents are placed closer to the oven's air inlet, as higher moisture content requires stronger hot air and faster dehydration. Leaves with lower moisture contents are placed further away to avoid overcooking and the resulting degradation of quality. This arrangement helps achieve uniformity and efficiency during the curing process.

[0104] S103 Oven Preparation and Self-Inspection: Before a fully loaded oven is sent into the baking process, it must first be transported to a charging station for centralized charging and a series of self-inspection operations to ensure that the oven is in optimal working condition. This process is broken down into the following steps:

[0105] T1 Power Monitoring: After the power is turned on, the system will continuously monitor the power status of the oven to confirm whether the power is working properly and whether the power is gradually increasing, ensuring that the baking process will not be interrupted due to insufficient power.

[0106] T2 Ventilation and Environmental Monitoring: Start the ventilation module of the baking oven, continuously ventilate to prepare the baking environment, and simultaneously obtain the current temperature and humidity data of the charging station to provide a reference for setting subsequent baking parameters.

[0107] T3 Monitoring Module Calibration: Activate the oven's built-in monitoring module and verify its accuracy and reliability by comparing the temperature and humidity data from the charging station to ensure precise control of environmental conditions during baking.

[0108] T4 Heating Module Test: Start the heating module and record the time required from startup to reaching the specified baking temperature to evaluate the response speed and efficiency of the heating system.

[0109] T5 Dehumidification function verification: Finally, start the dehumidification module and confirm whether its dehumidification function is working properly through actual operation. This is crucial for maintaining a suitable humidity environment inside the drying oven and helps protect the aroma components in the tobacco leaves.

[0110] Through the above-mentioned meticulous preparation and self-inspection steps, step S1 lays a solid foundation for the subsequent baking process, ensuring the optimization of baking efficiency and tobacco leaf quality.

[0111] Based on the above examples, in addition to meticulously controlling the baking oven and its internal environment, monitoring and managing the preheating room, humidity control room, withering room, and the shipping channels between them are equally crucial during the baking process. These links together constitute a complex baking system, and each link requires precise control to ensure that the tobacco leaves are in optimal condition throughout the entire process from pretreatment to final withering.

[0112] U1 In steps S1-S12 and / or before, start the transport channel between the preheating room, the humidity control room and the withering room, the transport channel including heating equipment, dehumidification equipment, ventilation equipment and air supply equipment, the air supply equipment is used to provide gas with parameters set by the monitoring system;

[0113] U2 controls the ventilation stone equipment of the shipping passage to discharge the exhaust gas from the preheating room to at least the humidity control room and / or the withering room, and detects the dry-bulb temperature, wet-bulb temperature and humidity of the exhaust gas in the shipping passage between the preheating room, the humidity control room and the withering room;

[0114] U3 controls the heating equipment and dehumidification equipment in the shipping channel to compensate for the exhaust gas according to the dry-bulb temperature, wet-bulb temperature, and humidity detected in the shipping channel, as well as the preset baking parameters of the preheating room, humidity control room, and withering room;

[0115] U4 continuously monitors the preheating room, humidity control room, and withering room, and when the required baking conditions cannot be met, it starts the air supply equipment to compensate for the conditions;

[0116] The heating compensation formula for the conditional compensation is:

[0117] P=(T1-T2) / H1*M-P'-N∑(Tx-T2) / H2;

[0118] Where P is the heating power of the air supply device, T1 is the target dry-bulb temperature, T2 is the current dry-bulb temperature, M and N are preset compensation coefficients, ∑(Tx-T2) is the temperature difference between the dry-bulb temperature of all ovens in the corresponding room and the current dry-bulb temperature, HP' is the heating power of the heating device, M is inversely proportional to the air intake of the corresponding room, and N is directly proportional to the air output of the ovens;

[0119] The humidity compensation formula for the conditional compensation is:

[0120] q2=(qz×Qz×ρz +q0×vh-Qr×ρr×wr)*k;

[0121] Among them, q2 is the estimated moisture content of the tobacco leaves in the baking oven after heating; qz is the moisture content of the steam in the baking oven; Qz is the steam flow rate; ρz is the density of the steam; q0 is the initial humidity of the mixture; Qr is the hot air flow rate; ρr is the density of the hot air; wr is the humidification amount of the hot air or the humidification ratio or the humidifier power.

[0122] Specifically, in step U1, at any stage between steps S1 through S12, or before these steps, the shipping corridors between the preheating room, humidity control room, and withering room must be activated in a timely manner. These corridors not only transport tobacco leaves between the various rooms but are also equipped with heating, dehumidification, ventilation, and air supply equipment to ensure the stability and suitability of the tobacco environment during transportation. The air supply equipment is particularly important, providing air at a specific temperature and humidity to the shipping corridors according to the parameters set by the monitoring system, creating an ideal transportation environment for the tobacco leaves.

[0123] Step U2: To optimize the environmental interaction between the baking rooms, the ventilation equipment in the shipping passage is designed to discharge the exhaust from the preheating room to at least the humidity control room and / or the withering room. This design not only helps to effectively utilize the heat and moisture in the preheating room, but also regulates the environmental conditions in the humidity control room and the withering room to a certain extent. At the same time, high-precision sensors are installed in the shipping passage between the preheating room, humidity control room, and withering room to monitor the dry-bulb temperature, wet-bulb temperature, and humidity of the exhaust in real time to ensure that these parameters always remain within the ideal range.

[0124] In step U3, based on the dry-bulb temperature, wet-bulb temperature, and humidity data detected by sensors in the shipping channel, as well as the preset baking parameters in the preheating room, humidity control room, and withering room, the control system intelligently adjusts the heating and dehumidification equipment in the shipping channel and performs necessary exhaust gas compensation. This process ensures that the environmental conditions during transportation are consistent with those in the baking room, preventing adverse effects on tobacco quality caused by sudden environmental changes.

[0125] In step U4, while continuously monitoring the environmental conditions in the preheating room, humidity control room, and withering room, if the preset baking conditions cannot be met, the system will immediately activate the air supply equipment to compensate for the conditions. The compensation strategy includes two parts: heating compensation and humidity compensation.

[0126] The heating compensation formula comprehensively considers the difference between the target dry-bulb temperature T1 and the current dry-bulb temperature T2, the heating equipment's heating efficiency H1, the preset compensation coefficients M and N (M is inversely proportional to the air intake, and N is proportional to the air output), the current heating equipment's heating power P', the temperature difference ∑(Tx-T2) between the dry-bulb temperature of all ovens in the room and the current dry-bulb temperature, and the heating efficiency H2, to accurately calculate the heating power P required for the air supply equipment. Similarly, the humidity compensation formula considers the moisture content qz of the steam in the oven, the steam flow rate Qz, the steam density ρz, the initial humidity of the mixture q0, the hot air flow rate Qr, the hot air density ρr, the hot air humidification amount wr (or humidification ratio, humidifier power), and the correction coefficient k to estimate the estimated moisture content q2 of the tobacco leaves in the oven after heating.

[0127] Activating the humidity control mode in the oven is a delicate and systematic process that includes the following key steps:

[0128] Step V101 begins. The system uses humidity sensor V101 to accurately obtain the target humidity qy set inside the oven—the desired humidity level. Simultaneously, it measures and records the current humidity qx of the room where the oven is located, serving as a reference humidity level. Using these two values, the system calculates the first humidity interval (qy - qx), which reflects the gap in humidity that the oven needs to adjust to achieve the target humidity.

[0129] Next, step V102 is executed, using the same humidity sensor to measure and record the actual humidity q1 of the oven at time t1. This reading is used to determine the second humidity interval (qy-q1), which reveals the direct difference from the current state to the target state.

[0130] Next, step V103 occurs, where the system predicts or measures the change in oven humidity over a preset time unit, Δt, after time t1, recording this as q2. Based on this data, the system calculates two additional humidity intervals: a third humidity interval (qy - q2), which reflects the difference between the oven's humidity and the target after Δt; and a fourth humidity interval (q2 - q1), which represents the change in oven humidity during Δt.

[0131] In step V104, the system performs complex calculations and uses the ratio of the sum of the second and third humidity intervals (i.e., (2*qy - q1 - q2)) to the fourth humidity interval (q2 - q1) as the required humidity interval ratio. This ratio provides important information about the trend and rate of humidity change, which is crucial for subsequent power adjustments.

[0132] Next, step V105 uses this ratio, combined with the ratio of the first humidity interval to time (reflecting the rate of humidity change) and a balance coefficient k (used to adjust the sensitivity of the adjustment value), to calculate the adjustment value for the oven's dryer power. This adjustment value is designed to ensure that humidity changes quickly and steadily approach the target value.

[0133] Finally, step V106 adds the adjusted value to a preset power base value, C, to obtain the final oven-adjusted dryer power, p. The formula p = k(2qy-q1-q2) (qy-qx) / [△t*(q2-q1)] + c accurately describes how the oven's power output is determined based on the current state, target state, time, and environmental factors.

[0134] In this formula, k serves as a balancing factor, adjustable based on actual needs to optimize humidity control. qx, qy, q1, and q2 represent the room humidity, target humidity, initial oven humidity, and oven humidity after Δt, respectively—all dynamically changing data points. Δt is a preset time interval used to observe humidity changes. C is a preset constant representing the oven's base power requirement. This entire process demonstrates the highly intelligent and precise nature of the oven's humidity control model.

[0135] The present invention also provides an embodiment of a tobacco leaf baking monitoring system, which includes:

[0136] The drying oven is used to sort the tobacco leaves and place them on the drying nets, place the drying nets into the drying oven according to the categories, and start charging after activating the standby charging mode of the drying oven;

[0137] a preheating room, for receiving the baking oven, activating the preheating mode of the baking oven, and providing the minimum temperature required for preheating;

[0138] The oven is also used to monitor the preheating parameters inside the oven after the preheating mode is started, and upload the monitoring video to the monitoring system. The preheating parameters include dry bulb temperature, wet bulb temperature, humidity and preheating time.

[0139] The monitoring system is used to confirm the tobacco leaf baking status through the monitoring video screen and adjust the preheating parameters of the corresponding baking oven. The baking oven processes the gas entering the preheating room inside the baking oven according to the preheating parameters to achieve the preheating parameters;

[0140] a first transfer device, configured to activate a first transfer mode of the oven after the preheating time reaches 0, and transfer the oven to a humidity-controlled room;

[0141] The baking oven is also used to pre-treat the gas entering the baking oven according to standard humidity control parameters after the first transfer equipment is started;

[0142] The humidity control room is used to activate the space-time mode of the drying oven and provide the minimum temperature and humidity required for humidity control. The standard humidity control parameters are the baking parameters required for humidity control of the tobacco leaves of the corresponding classification. The standard humidity control parameters include dry-bulb temperature, wet-bulb temperature, humidity and preheating time.

[0143] The oven is also used to monitor humidity control parameters inside the oven after the humidity control mode is activated, and upload monitoring videos to the monitoring system. The humidity control parameters include dry-bulb temperature, wet-bulb temperature, humidity, and humidity control time.

[0144] The monitoring system is also used to confirm the tobacco leaf baking status through the monitoring video screen and adjust the humidity control parameters of the corresponding baking oven. The baking oven processes the air entering the humidity control room inside the baking oven according to the humidity control parameters to achieve the humidity control parameters;

[0145] a second transfer device, configured to activate a second transfer mode of the baking oven after the humidity control time reaches 0, and transfer the baking oven to the withering room;

[0146] The oven is also used to precondition the gases entering the oven interior according to standard withering parameters;

[0147] A withering room, used to activate the withering mode of the baking oven and provide the minimum temperature and humidity required for humidity control. The standard withering parameters are the baking parameters required for withering of the tobacco leaves of the corresponding classification, and the standard withering parameters include dry-bulb temperature, wet-bulb temperature, humidity, and preheating time;

[0148] The oven is also used to monitor the wilting parameters inside the oven after the wilting mode is activated and upload monitoring videos to the monitoring system. The wilting parameters include dry bulb temperature, wet bulb temperature, humidity and wilting time.

[0149] The monitoring system is also used to confirm the tobacco leaf baking conditions through the monitoring video screen and adjust the withering parameters of the corresponding baking box. The baking box processes the gas entering the withering chamber inside the baking box according to the withering parameters to achieve the withering parameters, and ends the baking after the withering time reaches 0.

[0150] Specifically, the drying oven, a device designed specifically for tobacco leaf curing, operates with a highly automated and sophisticated process. First, workers neatly place the tobacco leaves on the drying nets according to designated categories. These nets are then placed into the drying oven one by one according to the required categories. After this, the oven's standby charging mode is activated, preserving power for the subsequent curing process.

[0151] The preheating room, the first step in the tobacco curing process, receives the tobacco ovens loaded with leaves. Once the ovens enter the preheating room, their preheating mode is activated. The room provides the minimum required preheating temperature, ensuring the internal temperature of the ovens gradually rises to the optimal starting point for curing. While preheating is active, sensors within the ovens monitor and record key preheating parameters, including dry-bulb temperature, wet-bulb temperature, humidity, and preheating time. These parameters are not only recorded in real time but also uploaded to the monitoring system as video, enabling operators to intuitively understand and adjust the preheating process to ensure optimal curing conditions.

[0152] When the preheating time reaches a preset value, the first transfer device is activated, safely and efficiently transferring the oven from the preheating room to the humidity control room. During the transfer process, the oven pre-conditions the incoming air according to preset standard humidity control parameters, preparing it for the next humidity control stage.

[0153] The humidity control room, a key component of the baking process, provides the minimum temperature and humidity required for humidity control in the baking oven. Standard humidity control parameters, including dry-bulb temperature, wet-bulb temperature, humidity, and humidity control duration, are carefully set based on tobacco leaf classification to ensure optimal humidity levels during the baking process. When humidity control mode is activated, sensors within the baking oven once again monitor and record humidity control parameters, while also uploading surveillance video for operator monitoring and adjustment.

[0154] When the humidity control time reaches a preset value, the second transfer device is activated, transferring the drying oven from the humidity control room to the withering room. In the withering room, the oven pre-conditions the internal air according to preset standard withering parameters. These withering parameters, also carefully set based on the tobacco leaf type, include dry-bulb temperature, wet-bulb temperature, humidity, and withering time, designed to promote the optimal evaporation of moisture from the tobacco leaves and achieve the ideal withering effect.

[0155] After withering mode is activated, the oven continues to monitor and record withering parameters, while also uploading the monitoring video. This allows operators to monitor the tobacco leaf's curing progress in real time and adjust parameters as needed. When the withering time reaches the preset value, the curing process is complete.

[0156] In summary, the baking oven, preheating room, humidity control room, withering room, transfer equipment, and monitoring system together form a highly automated and sophisticated tobacco leaf curing system. This system not only improves curing efficiency and quality, but also reduces the cost and risk of manual intervention.

[0157] The loading corridor between the preheating room, humidity control room, and withering room is not only a vital link connecting these three critical curing processes, but also a comprehensive system integrating multiple environmental control devices. This transport corridor is meticulously designed with heating, dehumidification, ventilation, and air supply equipment to ensure that the tobacco leaves are continuously maintained in the optimal curing environment during transportation.

[0158] Ventilation equipment plays a crucial role in the transfer corridor. It not only effectively directs exhaust air from the preheating room to the humidity control room and / or withering room, ensuring optimal heat utilization and natural environmental regulation, but also provides real-time monitoring of the exhaust dry-bulb temperature, wet-bulb temperature, and humidity within the transfer corridor. This data provides an accurate basis for subsequent compensation.

[0159] Heating and dehumidification equipment meticulously compensate for exhaust gas based on environmental parameters detected by the ventilation equipment and preset curing parameters for the preheating room, humidity control room, and withering room. If the exhaust gas temperature or humidity deviates from preset values, these devices quickly respond by heating or dehumidifying the exhaust gas to return the parameters to the optimal curing range, ensuring that the tobacco leaves are not adversely affected by environmental changes during transportation.

[0160] The air supply system is a backup environmental control method. It continuously monitors the environmental conditions in the preheating room, humidity control room, withering room, and transfer corridor. If it finds that any link cannot meet the required baking conditions, the air supply system will immediately start to compensate for the baking environment by adding fresh air or adjusting the indoor gas composition, ensuring the smooth progress of the entire baking process.

[0161] Temperature monitoring equipment is also an integral part of the transfer corridor. It monitors temperature fluctuations in each room and the transfer corridor, ensuring the baking environment remains within preset ranges. If the temperature fluctuates abnormally, the temperature monitoring equipment immediately issues an alarm, prompting operators to take timely action to adjust the temperature.

[0162] To further improve baking efficiency and energy utilization, heat pumps are installed in the transfer tunnels. These heat pumps effectively transfer heat from overheated rooms or transfer tunnels to cooler rooms or baking ovens, achieving heat recycling and temperature compensation. This design not only helps reduce energy consumption during the baking process but also improves the stability and uniformity of the baking environment, providing a strong guarantee for improving tobacco leaf baking quality.

[0163] The tobacco leaf curing monitoring system is a comprehensive management platform that integrates multiple advanced subsystems to ensure that tobacco leaves are always in optimal condition during the curing process, thereby improving curing quality and efficiency. In addition to basic monitoring functions, the system also includes the following key components:

[0164] Oven Monitoring Subsystem: Once the oven is fully charged, this subsystem automatically determines the preheating, humidity control, and withering parameters required for each curing process for the currently sorted tobacco leaves. It then monitors real-time oven data, including but not limited to room location, dry-bulb temperature, wet-bulb temperature, humidity, and elapsed preheating, humidity control, and withering times. This data not only provides intuitive feedback on the oven's status but is also reported to a higher-level monitoring center for further analysis and optimization.

[0165] Oven Transfer System: This system intelligently distributes incoming ovens according to the size of the room they are in, ensuring they are evenly spaced, optimizing space utilization and baking efficiency. Using precise algorithms and automated equipment, the Oven Transfer System automatically adjusts the position of ovens to suit varying baking needs and room layouts.

[0166] Room Monitoring Subsystem: This subsystem receives real-time baking data from all fully charged ovens and creates a three-dimensional map of the room based on each oven's location. These maps not only display the temperature and humidity distribution within the room but also visually reflect environmental changes during the baking process. This data allows operators to more accurately understand the state of the baking environment, enabling them to make more informed decisions.

[0167] Oven Transfer System (Advanced Functionality): In addition to basic transfer functions, the oven transfer system also receives a three-dimensional image generated by the room monitoring subsystem and intelligently adjusts the position of each oven based on the preheating, humidity control, or wilting parameters currently required. This dynamic adjustment not only helps optimize the baking environment but also ensures that each oven is transferred at the appropriate time to avoid over- or under-baking. Furthermore, when the preheating, humidity control, or wilting time has expired, the oven transfer system automatically triggers the transfer process, moving the oven to the next processing step, ensuring continuity and efficiency throughout the baking process.

[0168] Furthermore, based on the above embodiment, it also includes: a rectangular emergency room, wherein the rectangular emergency room is provided with a plurality of monitoring devices evenly distributed in the longitudinal direction, and a heating and dehumidifying device is provided only on one side in the longitudinal direction to cause a gradient change in temperature and humidity in the longitudinal direction, wherein the monitoring devices are used to monitor the temperature and humidity at corresponding positions in the rectangular emergency room;

[0169] Multiple emergency passages; used to connect the rectangular emergency room with the preheating room, humidity control room, and withering room, and provide preset temperature and humidity;

[0170] An emergency control device, used to draw a three-dimensional schematic diagram of the temperature and humidity of the rectangular emergency room based on the monitoring device;

[0171] Emergency transfer equipment, used to urgently transfer the baking ovens inside the preheating room, humidity control room, withering room and transfer passage to the rectangular emergency room through the emergency passage when the preheating room, humidity control room, withering room and transfer passage fail;

[0172] The emergency control device is further configured to call the emergency transfer device to place the corresponding baking oven at a position corresponding to the temperature and humidity according to the temperature and humidity three-dimensional diagram and the temperature and humidity corresponding to the mode of the baking oven;

[0173] Emergency energy transfer equipment is used to transfer the heat of the failed room or transfer channel to the rectangular emergency room when the preheating room, humidity control room, withering room and transfer channel fail. The emergency energy transfer equipment includes heat pump equipment.

[0174] Specifically, the rectangular emergency room, a uniquely designed facility, features multiple monitoring devices meticulously deployed along its length. These devices are not only sufficient in number but also evenly distributed, ensuring comprehensive and accurate monitoring of the emergency room's internal environment. Each monitoring device carries a crucial mission: capturing and recording temperature and humidity data at its location in real time, providing valuable first-hand information for subsequent emergency response and environmental regulation. Particularly noteworthy is the clever installation of heating and dehumidification equipment along one side of the rectangular emergency room's length. This layout not only saves space but also successfully creates a gradient effect where temperature and humidity gradually change along the length, providing diverse environmental conditions in different areas to meet various emergency needs.

[0175] To further enhance the flexibility and efficiency of emergency response, multiple emergency corridors were meticulously planned and installed. Like lifelines, they seamlessly connect the rectangular emergency room with the preheating room, humidity control room, and withering room. These corridors not only ensure rapid connectivity between key rooms but also provide air at preset temperatures and humidity levels, effectively supporting the needs of different operational phases.

[0176] The emergency control device, the intelligent core of the entire emergency management system, uses data collected by monitoring equipment to quickly create a detailed three-dimensional diagram of the temperature and humidity inside the rectangular emergency room. This intuitive graphical display not only helps staff quickly grasp the environmental conditions within the emergency room but also provides strong data support for subsequent emergency decision-making. Through this device, staff can clearly see the temperature and humidity distribution in each area of ​​the emergency room, allowing them to more accurately formulate emergency response plans.

[0177] In the event of a sudden failure in the preheating room, humidity control room, withering room, or transfer corridor, the emergency transfer equipment becomes a crucial tool for rescuing the situation. It rapidly responds by urgently transferring the ovens in these rooms or corridors through the emergency corridor to the rectangular emergency room, ensuring uninterrupted production. Even more advanced, the emergency control equipment intelligently calls upon the emergency transfer equipment based on a temperature and humidity 3D diagram and the specific temperature and humidity conditions required for the oven's current operating mode, precisely placing the oven in the rectangular emergency room at the optimal temperature and humidity for its operation. This intelligent scheduling method not only improves the efficiency of emergency response but also maximizes production efficiency and product quality.

[0178] Furthermore, the addition of emergency energy transfer equipment provides an additional layer of security to this emergency response system. In the event of a malfunction in the preheating room, humidity control room, withering room, or transfer corridor, it quickly activates and utilizes advanced technologies such as heat pumps to efficiently transfer heat from the malfunctioning area or corridor to the rectangular emergency room. This function not only ensures that environmental conditions within the emergency room are maintained but also provides stable energy support for the continued operation of equipment such as the oven. Through the coordinated operation of this series of emergency measures and equipment, the rectangular emergency room has established an efficient, intelligent, and reliable emergency response system, providing solid support for responding to various emergencies.

[0179] Furthermore, based on the above embodiment, it also includes: vertically arranged interconnected rooms, and dehumidification equipment is provided between the rooms, and the temperature and humidity of each room decrease step by step according to the flow direction from bottom to top;

[0180] Transfer drones, used to move ovens from one room up or down to another;

[0181] It also includes at least one other set of vertically connected rooms, and all preheating rooms, humidity control rooms, and withering rooms have different temperatures;

[0182] Inter-building channels are used to provide drones with communication channels between buildings;

[0183] Energy circulation equipment for recovering energy from the entire building, the energy circulation equipment including a heat pump;

[0184] The energy circulation equipment also includes heating equipment for providing heat to associated buildings, including office buildings and cafeterias.

[0185] Specifically, the design of the series of vertically arranged and interconnected rooms is ingenious and practical, not only optimizing space utilization but also cleverly incorporating intelligent environmental control. These rooms are closely connected vertically, and advanced dehumidification equipment is installed between each floor to ensure the air in the rooms remains dry, effectively preventing the various problems caused by moisture. Even more uniquely, the temperature and humidity within the rooms are carefully controlled, following the natural flow of air from bottom to top, gradually decreasing, creating a microclimate that meets production needs while being energy-efficient and environmentally friendly. This design not only improves work efficiency but also greatly enhances living and working comfort.

[0186] To further enhance the flexibility and interoperability of the rooms, the innovative technology of transfer drones has undoubtedly added unlimited possibilities to the entire system. These drones can respond quickly, accurately and efficiently transporting ovens from one room up or down to another, regardless of the distance, completing the transfer task in a short time. This feature not only significantly shortens transfer time but also reduces manual intervention, enhancing the overall automation and intelligence of the operation.

[0187] The building also contains at least one other set of vertically interconnected rooms, each following the same temperature and humidity gradient principle, but each with its own unique preheating room, humidity control room, and withering room. The temperature of each room is precisely set to meet the needs of different production or research projects. This design not only enhances the system's flexibility, but also allows different projects to operate without interfering with each other, operating in an efficient and orderly environment.

[0188] To enhance connectivity between buildings, carefully designed and constructed inter-building passageways not only provide convenient access for drones but also ensure rapid evacuation and material transfer for the entire complex in emergencies. These passageways are spacious, bright, and clearly marked, greatly facilitating the movement of personnel and the allocation of supplies.

[0189] Energy recycling equipment is the core of the building's energy-saving and environmentally friendly approach. It includes an advanced heat pump system that efficiently recovers energy throughout the building and converts it into usable heat or cooling energy for applications such as regulating indoor temperature and providing hot water. This system not only significantly reduces energy consumption but also carbon emissions, making a positive contribution to environmental protection.

[0190] Even more thoughtfully, the energy recycling equipment is also equipped with heating equipment. These devices convert the recovered energy into warm air, which is piped to related buildings such as the office building and cafeteria, providing a comfortable indoor environment for staff and visitors. This design not only improves energy utilization but also ensures that the entire building complex remains warm in winter, bringing great convenience to people's daily work and life.

[0191] Advanced wireless power transmission technology has been integrated into a series of facilities, including preheating rooms, humidity control rooms, withering rooms, and transfer corridors, revolutionizing energy transmission. Specifically, these rooms and corridors are equipped with wireless power transmission equipment that efficiently converts traditional electrical energy into electromagnetic energy and transmits it wirelessly through space, eliminating the cumbersome and restrictive nature of traditional wiring connections and improving the flexibility and safety of energy utilization.

[0192] Room heating devices play a crucial role in the preheating room. These devices receive electromagnetic energy from the wireless power transmitter and convert it into heat, providing stable and uniform heating for the preheating room. This design not only improves heating efficiency but also reduces energy waste, allowing the preheating room to quickly reach and maintain the desired temperature.

[0193] Humidity-controlled rooms are equipped with advanced dehumidification equipment. These devices also utilize wireless power transmission technology to receive electromagnetic energy. Through efficient dehumidification mechanisms, they effectively remove moisture from incoming air, ensuring precise control of humidity within the room. This is crucial for storing or processing items that require a specific humidity environment.

[0194] In addition to the necessary heating and dehumidification equipment, the withering room may also be equipped with a drying oven. This oven heating device receives electromagnetic energy or draws power directly from an internal battery to heat the air inside the oven to achieve a specific drying or processing effect. Furthermore, to further enhance efficiency and flexibility, the oven may also be equipped with specialized dehumidification equipment to remove moisture from the air entering the oven, ensuring a smooth drying process.

[0195] Furthermore, the transport corridor, serving as a link between the various rooms, is also equipped with wireless power transmission equipment. This not only provides power to the equipment within the corridor but also offers a convenient charging solution for passing vehicles and robots. The wireless charging equipment for ovens, in particular, charges the oven batteries during transport, ensuring sufficient power when the oven reaches the next processing point, thereby improving the efficiency and reliability of the entire system.
