Description
Technical Field
[0001] This application relates to the field of tobacco curing barn technology, specifically to a method, device, electronic equipment, and program product for determining the opening degree of an air damper. Background Technology
[0002] Tobacco curing is a technology that involves heating, drying, and oxidizing freshly picked tobacco leaves in a curing barn to achieve the appropriate moisture content, enhance the aroma and flavor, and ultimately create tobacco products. The main equipment in a curing barn includes heat pumps, dampers, and circulating fans. The dampers include cold air dampers and dehumidification dampers. The opening of the cold air damper can be set by adjusting its angle. The dehumidification dampers expel moisture from the curing barn.
[0003] In existing technologies, the opening and closing angle of the cold air damper is determined by obtaining the actual wet-bulb temperature inside the tobacco curing barn through a sensor, and then comparing the actual wet-bulb temperature with a pre-set target wet-bulb temperature. Because existing technologies only consider the temperature changes in the current environment, they are prone to excessive temperature and humidity fluctuations, excessively rapid dehumidification, and sudden temperature drops, which are detrimental to tobacco curing.

[0054] or,
[0055] When the fifth judgment result indicates that the wet-bulb temperature offset at the current sampling time is not greater than the wet-bulb temperature offset at the sampling time, the damper opening is reduced.

The damper opening is determined by acquiring the wet-bulb temperature offset at the current sampling moment and the wet-bulb temperature offset at the previous sampling moment. Because this invention comprehensively considers the wet-bulb temperature offsets at both the previous and current sampling moments when determining the damper opening, the trend of wet-bulb temperature change can be measured more precisely and accurately based on this offset. Therefore, determining the damper opening based on this offset achieves refined damper control, avoiding adverse effects on tobacco leaves caused by excessively rapid dehumidification and sudden temperature drops.

[0068] Figure 3 This is a schematic diagram of the hardware structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation
[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0070] In tobacco processing, tobacco leaf curing is a crucial step that directly impacts the quality of the tobacco product. Currently, the tobacco curing process can be divided into ten stages. Before curing begins, curing personnel input curing process parameters based on the tobacco leaf variety, growth location, maturity, and other characteristics. These parameters for each stage are then input into the controller via an interactive panel as target values to control the operation of each piece of equipment. The curing process parameters include dry-bulb temperature, wet-bulb temperature, heating time, temperature control time, and airflow.
[0071] Dry bulb temperature is the target temperature for the curing stage, representing the temperature of the tobacco curing barn. Wet bulb temperature is the humidity of the tobacco curing barn during the curing stage, representing the humidity of the tobacco curing barn. Heating time is the time required for the dry bulb temperature to rise from the previous stage to the current stage. Constant temperature time is the time during which the dry bulb and wet bulb temperatures remain constant during the curing stage. Wind speed is the air outlet speed of the tobacco curing barn stage, which is achieved by setting "high wind speed" or "low wind speed".
[0072] Dry-bulb and wet-bulb temperatures can be read using sensors. Currently, tobacco curing barns control equipment operation by comparing target and actual values of dry-bulb and wet-bulb temperatures.
[0073] The main equipment in a tobacco curing barn includes a heat pump, cold air dampers, dehumidification dampers, and circulating fans. The heat pump is the heating source for the barn, and the fans blow heat into it, raising the temperature. The dampers include cold air dampers and dehumidification dampers. The opening and closing size of the cold air dampers can be set by adjusting their angle. The dehumidification dampers remove moisture from the barn; the dehumidification speed is mainly determined by the cold air dampers. The larger the angle of the cold air dampers, the faster the cold air enters and the faster the moisture is removed. The fans are mainly used to blow the heat generated by the heat pump into the barn, and they typically have two speed settings: high and low.
[0074] The opening angle of the cold air damper in the tobacco curing barn is determined by using sensors to obtain the actual wet-bulb temperature inside the barn. This actual wet-bulb temperature is then compared with a pre-set target wet-bulb temperature to determine the damper's opening angle. For example, if the difference between the actual wet-bulb temperature and the pre-set target temperature exceeds 0.5°C, the damper opening is adjusted to 15°; if the difference is between 0.5°C and 1°C, the opening is adjusted to 30°. However, current technology only considers the temperature changes in the current environment, which can easily lead to excessive temperature and humidity fluctuations, excessively rapid dehumidification, and sudden temperature drops, all of which are detrimental to tobacco curing.
[0075] The damper opening determination method provided in this invention obtains the wet-bulb temperature offset at the current sampling time and the wet-bulb temperature parameter offset at the previous sampling time to determine the wet-bulb temperature change trend and thus determine the damper opening. Because the damper opening in this invention takes into account the wet-bulb temperature change trend, it achieves refined damper control, avoiding adverse effects on tobacco leaves from excessively rapid dehumidification and sudden temperature drops.
[0076] Exemplary methods
[0077] The following is combined Figure 1 This application provides a detailed description of a method for determining the opening degree of a damper.
[0078] like Figure 1 As shown, the method may include the following steps:
[0079] S100: Obtain the wet-bulb temperature parameters at the current sampling time and the previous sampling time, respectively. The wet-bulb temperature parameters include the target temperature and the actual temperature of the wet bulb.
[0080] The wet-bulb temperature parameter can include the target temperature and the actual temperature. The target temperature can be determined based on the current curing stage and the ambient temperature of the curing barn. The target temperature can be a pre-set target wet-bulb temperature. The actual temperature can be the temperature obtained by a sensor. When the actual temperature is higher than the target temperature, it indicates high humidity in the curing barn, and the damper will open to expel the moisture. When the actual temperature is lower than the target temperature, the damper will close to prevent moisture from escaping.
[0081] In the tobacco curing process, each curing stage includes two processes: heating and temperature control. During the temperature control stage, the target wet-bulb temperature is pre-set by the staff and remains constant. During the heating stage, the wet-bulb temperature changes; its initial temperature is the target wet-bulb temperature of the previous stage, and its endpoint is the target wet-bulb temperature of the current stage. The heating time can be pre-set by the tobacco curing staff according to the curing process.
[0082] For ease of description, let's use S. 湿球 (m) represents the set wet-bulb temperature for the m-th stage, S 升温时间 (m) represents the set heating time for the m-th stage. S 湿球 (0) represents the ambient wet-bulb temperature at the start of flue-cured tobacco. j represents the heating or isothermal stage, j=1 for the heating stage; j=2 for the isothermal stage. The sampling time is represented by t, t=1, 2, 3...
[0083] During the baking process, the target wet-bulb temperature W is collected at time t. 目标 (t) is calculated as follows:
[0084] W 目标 (t)=S 湿球 (m)+[S 湿球 (m)-S 湿球 (m-1)] / S 升温时间 (m)*ij=1
[0085] W 目标 (t)=S 湿球 (m) j=2
[0086] Among them, W 目标 (t) represents the target temperature of the ball at sampling time t; S 湿球 (m) represents the target wet-bulb temperature set in the m-th stage, S 湿球(m-1) represents the target wet-bulb temperature set in the (m-1)th stage; S 升温时间 (m) represents the set heating time for the m-th stage; j=1 represents the heating stage; j=2 represents the constant temperature stage; i represents the data sampling time interval.
[0087] The sampling time can be determined based on the characteristics of the tobacco curing barn and the curing process.
[0088] The actual wet-bulb temperature can be read by a sensor. In practical applications, the actual wet-bulb temperature of the upper and lower sheds in the tobacco curing barn can be read by the sensor. Currently, the tobacco curing barn adopts the upper shed control method, that is, the actual wet-bulb temperature of the upper shed is used as the actual wet-bulb temperature.
[0089] In one example, the sampling time can be set to 60 seconds.
[0090] S120: Based on the wet-bulb temperature parameters, determine the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time; the wet-bulb temperature offset represents the deviation between the actual wet-bulb temperature and the target wet-bulb temperature.
[0091] For ease of description, W 实际 (t), W 目标 (t) represent the actual temperature and target temperature of the wet bulb at sampling time t during the baking process, respectively; W 实际 (t-1), W 目标 (t-1) represents the actual wet-bulb temperature and the target wet-bulb temperature at sampling time t-1 during the baking process. The wet-bulb temperature offset at the previous sampling time can then be expressed as W. 实际 (t-1)-W 目标 (t-1), the wet-bulb temperature offset at the current sampling time can be expressed as W. 实际 (t)-W 目标 (t).
[0092] S140: Determine the damper opening based at least on the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time.
[0093] The wet-bulb temperature offset at the previous sampling time represents the temperature change trend of the wet bulb in the curing barn at that time, while the wet-bulb temperature offset at the current sampling time represents the temperature change trend at that time. By comparing the temperature change trends at the previous and current sampling times, the trend of wet-bulb temperature change can be measured more accurately and precisely, ensuring an appropriate dehumidification rate in the curing barn. Dehumidification rates that are too fast or too slow will adversely affect the tobacco leaves. The damper is adjusted based on the wet-bulb temperature offset to ensure an appropriate damper opening. If the damper opening is too large, excessive outside air will enter, causing a decrease in dry-bulb temperature. If the damper opening angle is too large, the heat pump heating rate cannot keep up with the decompression rate, resulting in an excessive difference between the actual and target dry-bulb temperatures, which will also adversely affect the tobacco leaves.
[0094] The method for determining the damper opening provided in this invention obtains the wet-bulb temperature offset at the current sampling time and the wet-bulb temperature offset at the previous sampling time to determine the wet-bulb temperature change trend and thus determine the damper opening. Since the damper opening in this invention considers the wet-bulb temperature offset at both the current and previous sampling times, and thus determines the wet-bulb humidity change trend based on this offset, the measurement of the wet-bulb temperature change trend is more accurate. Adjusting the damper opening according to this wet-bulb temperature change trend ensures that the damper opening meets the baking requirements, avoiding excessively rapid dehumidification and sudden temperature drops that could adversely affect the tobacco leaves.
[0095] In one embodiment, determining the damper opening based at least on the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time may include:
[0096] Based on the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time, the opening degree of the damper is determined with the goal of ensuring that the baking environment meets the set baking environment requirements.
[0097] The baking environment requirements include at least one of the following: the wet-bulb temperature deviation is within the target temperature range, the wet-bulb temperature change rate is within the target wet-bulb temperature change rate range, and the dry-bulb temperature change rate is within the target dry-bulb temperature change rate range, and the wet-bulb temperature must be within the target temperature range.
[0098] In one example, the target temperature range can be set according to the actual situation. For example, the target temperature range can be ±0.3°. When the wet-bulb temperature deviation is within the target temperature range, it can be considered as normal fluctuation.
[0099] The wet-bulb temperature change rate describes the rate of change of wet-bulb temperature, used to describe the deviation between the actual wet-bulb temperature and the target temperature at two adjacent sampling times. For ease of description, R...湿度 (t) is used to represent the rate of change of wet-bulb temperature, R 湿度 The formula for calculating (t) can be expressed as:
[0100] R 湿度 (t)=[W 实际 (t)-W 实际 (t-1)] / [W 目标 (t-1)-W 实际 (t-1)]
[0101] R 湿度 (t)>1 indicates that the actual wet-bulb temperature first approaches the target temperature, but the change is too large and exceeds the wet-bulb target temperature;
[0102] 0≤R 湿度 (t)≤1 indicates that the wet-bulb temperature has not changed or is approaching the target temperature;
[0103] R 湿度 (t)<0 indicates that the wet-bulb temperature is deviating from the target temperature.
[0104] Under normal circumstances, 0≤R 湿度 (t)≤1, R 湿度 The larger (t) is, the faster the wet-bulb temperature approaches the target value. Considering the desiccation rate, R 湿度 (t) should be within a certain range, which can be taken as 0.2. <R 湿度 (t)≤0.4. If 0.4≤R 湿度 If (t)≤1, it indicates that the moisture is being removed too quickly; if 0 <R 湿度 If (t)≤0.2, it indicates that the moisture removal is too slow.
[0105] Use S 干球 (m) represents the set dry-bulb target temperature for the m-th stage, S 升温时间 (m) represents the set heating time for the m-th stage. S 干球 (0) represents the actual dry bulb temperature at the start of the flue-curing process. The target dry bulb temperature G at sampling time t during the curing process is also represented. 目标 (t) is calculated as follows:
[0106] G 目标 (t)=S 干球 (m)+[S 干球 (m)-S 干球 (m-1)] / S 升温时间 (m)*ij=1
[0107] G 目标 (t)=S 干球 (m) j=2
[0108] Among them, G 目标(t) represents the target temperature of the ball at sampling time t; S 干球 (m) represents the target dry-bulb temperature set in the m-th stage, S 干球 (m-1) represents the target dry bulb temperature set in the (m-1)th stage; S 升温时间 (m) represents the set heating time for the m-th stage; j=1 represents the heating stage; j=2 represents the constant temperature stage; i represents the data sampling time interval.
[0109] The rate of change of dry-bulb temperature describes the rate of change of dry-bulb temperature, used to describe the deviation between the actual and target temperatures of the dry bulb at two adjacent sampling times. For ease of description, G... 实际 (t) represents the actual dry-bulb temperature at time t during the baking process; G 目标 (t) represents the target dry-bulb temperature at time t during the baking process. Then, the actual dry-bulb temperature at the previous sampling time is G. 实际 (t-1), the target dry-bulb temperature is G 目标 (t-1).
[0110] R 温度 The formula for calculating (t) can be expressed as:
[0111] R 温度 (t)=[G 实际 (t)-G 实际 (t-1)] / G 目标 (t)
[0112] R 温度 (t)>0 indicates that the temperature is rising from t-1 to the sampling time t.
[0113] R 温度 (t) = 0, indicating that the temperature did not change from t-1 to the sampling time t;
[0114] R 温度 (t)<0 indicates that the temperature is decreasing from t-1 to the sampling time t.
[0115] Under normal circumstances, the actual dry-bulb temperature will fluctuate around the target dry-bulb temperature, and the deviation will not be too large. When the damper is opened, cold air will enter, causing the dry-bulb temperature to drop. To prevent the dry-bulb temperature from dropping too quickly, R... 温度 (t) should be within a certain range. Under normal circumstances, R 温度 (t)≥-0.1, if R 温度 If (t) < -0.1, it indicates that the temperature is decreasing too quickly.
[0116] In a tobacco curing barn environment, the opening degree of the damper directly affects the wet-bulb temperature, wet-bulb temperature change rate, dry-bulb temperature, and dry-bulb temperature change rate. When the requirements for the curing environment during the tobacco curing process are determined, such as the target temperature range, target wet-bulb temperature change rate range, and target dry-bulb temperature change rate range mentioned above, all of which are fixed values, the damper size can be adjusted based on the currently determined wet-bulb temperature offset at the previous sampling time and the current sampling time to ensure that the curing environment of the tobacco curing barn meets the aforementioned requirements. For example, this means ensuring that the wet-bulb temperature is within the aforementioned target temperature range, and / or that the wet-bulb temperature change rate is within the aforementioned target wet-bulb temperature change rate range, and / or that the dry-bulb temperature change rate is within the aforementioned target dry-bulb temperature change rate range.
[0117] The method provided in this invention determines the damper opening based on the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time, with the goal of ensuring the baking environment meets the set baking environment requirements. Since the baking environment requirements include at least one of the following: the wet-bulb temperature offset being within the target temperature range, the wet-bulb temperature change rate being within the target wet-bulb temperature change rate range, and the dry-bulb temperature change rate being within the target dry-bulb temperature change rate range, and necessarily includes the wet-bulb temperature offset at the previous sampling time, it can take into account the wet-bulb temperature change trend. Simultaneously, when adjusting the damper opening, it considers both the wet-bulb temperature change rate and the dry-bulb temperature change rate, ensuring an appropriate rate of moisture removal without damaging the tobacco leaves. It also avoids excessive damper opening, which could lead to a sudden drop in dry-bulb temperature.
[0118] In one embodiment, the baking environment requirements include a wet-bulb temperature offset within a target temperature range, a wet-bulb temperature change rate within a target wet-bulb temperature change rate range, and a dry-bulb temperature change rate within a target dry-bulb temperature change rate range.
[0119] Based on the wet-bulb temperature offset at the previous sampling time and the wet-bulb temperature offset at the current sampling time, the opening degree of the damper is determined with the goal of ensuring that the baking environment meets the set baking environment requirements. This can include:
[0120] Determine whether the wet-bulb temperature offset at the previous sampling time is within the first threshold range to obtain a first determination result, and determine whether the wet-bulb temperature offset at the current sampling time is within the second threshold range to obtain a second determination result;
[0121] Based on the first and second judgment results, the opening degree of the air vent is determined with the goal of making the baking environment meet the set baking environment requirements.
[0122] In this implementation, the wet-bulb target temperature at the previous sampling time and the current sampling time can be determined using the above calculation formula.
[0123] W 目标 (t)=S 湿球 (m)+[S 湿球 (m)-S 湿球 (m-1)] / S 升温时间 (m)*ij=1
[0124] W 目标 (t)=S 湿球 (m) j=2
[0125] The actual wet-bulb temperature at the previous sampling time and the current sampling time can be obtained through a temperature sensor. In practical applications, the actual wet-bulb temperature can be obtained directly by reading the control panel.
[0126] Based on the actual wet-bulb temperature and target temperature at the previous sampling time, the wet-bulb temperature offset at the previous sampling time is determined, and then it is determined whether the wet-bulb temperature offset at the previous sampling time is within the first threshold range.
[0127] The method for determining the wet-bulb temperature offset at the current sampling moment is similar to that at the previous moment, and will not be repeated here.
[0128] Determine whether the temperature offset at the previous sampling time is within the first threshold range, which can be ±0.5℃, and obtain the first judgment result.
[0129] Determine whether the temperature offset at the current sampling time is within the second threshold range, which can be ±0.5℃, and obtain the second determination result.
[0130] Since the temperature offset at the previous sampling time reflects the humidity change trend in the tobacco curing barn during the previous sampling period, and the temperature offset at the current sampling time reflects the humidity change trend in the tobacco curing barn during the current sampling period, combining the humidity change trends in the two sampling periods can more accurately determine the humidity change trend in the tobacco curing barn. This allows us to determine whether the current humidity in the tobacco curing barn meets the requirements of the curing environment. When the humidity in the tobacco curing barn is high, we can increase the opening of the damper to expel the moisture; or when the humidity in the tobacco curing barn is low, we can decrease the opening of the damper to slow down the rate of humidity change in the tobacco curing barn.
