[0002] In the tobacco industry, the process from harvesting tobacco leaves to forming the final cigarette involves a series of complex steps. Among these, the storage of tobacco shreds is crucial, as factors such as the ambient temperature and pressure differences during storage directly affect the quality of the tobacco. However, existing conventional factory air conditioning systems use traditional central air conditioning control methods. When storing different types of tobacco shreds, this not only requires constant manual adjustment to meet the storage environment parameters, but also cannot guarantee the precision and stability of these parameters.

The blower is located at the air supply duct inlet of the target factory building. When the environmental control mode is the pressure control mode, the target opening and closing angle of the air outlet position furthest from the air outlet position is determined based on the air outlet position of the target factory building. The opening and closing angle of the blower fan blades is adjusted to the target opening and closing angle. The air supply speed of the blower is adjusted based on the pressure difference between the target control pressure difference and the real-time pressure difference of the target factory building and the target opening and closing angle.

The blower device is set at the air supply duct inlet of the target factory building.

[0013] First, some of the embodiments of this application will be explained below to facilitate understanding by those skilled in the art.

[0014] A Programmable Logic Controller (PLC) is a specific computer hardware device used in automated control systems. It monitors and controls mechanical, electrical, and technological processes through programmable logic functions and digital / analog input / output interfaces.

[0015] Proportional-Integral-Derivative (PID) control is a commonly used control algorithm widely applied in industrial automation and process control. It achieves precise system control by adjusting the control signal based on a comprehensive consideration of current, past, and future errors. Proportional control adjusts the control signal proportionally to the current error, making the control signal linearly related to the error. When the error is large, proportional control can respond quickly and provide a larger control signal to accelerate the system's response speed. Integral control adjusts the control signal based on the cumulative value of past errors, eliminating steady-state errors. Even with system parameter errors or external disturbances, the integral action continuously adjusts the control signal, bringing the system output closer to the setpoint. Derivative control adjusts the control signal based on the rate of change of future errors, predicting future error trends and adjusting the control signal accordingly to reduce the rate of error change, improving system stability and anti-interference capabilities.

[0016] Please see Figure 1 , Figure 1 This document illustrates a system architecture diagram of a method for controlling internal storage environment parameters in a factory, as provided in an embodiment of this specification.

[0017] like Figure 1 As shown, the system architecture of the method for controlling the internal storage environment parameters of the factory building can include at least a terminal 10, a server 20, and a network 30.

[0018] Terminal 10 includes, but is not limited to, electronic devices such as smartphones, desktop computers, tablets, laptops, smart speakers, digital assistants, and smart wearable devices, and may also be software running on the aforementioned electronic devices, such as applications. Optionally, the operating system running on the electronic device may include, but is not limited to, Android, iOS, Linux, and Windows. Optionally, terminal 10 provides users with adjustable parameters of the factory's internal storage environment. Terminal 10 can obtain operation instructions from the application programming interface and send parameter adjustment requests to server 20.

[0019] Server 20 can provide background services for terminal 10. Based on the parameter adjustment request sent by terminal 10, server 20 will obtain a series of adjustment instructions and transmit the adjustment instructions to other terminals 10 through network 30. Specifically, server 20 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0020] Network 30 is a medium used to provide a communication link between terminal 10 and server 20. Network 30 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0021] 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.

[0022] 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.

[0023] Please refer to the following. Figure 2 , Figure 2 This specification illustrates an overall flowchart of a method for regulating internal storage environment parameters in a factory, which can be used in a server control system.

[0024] like Figure 2 As shown, the method for regulating the internal storage environment parameters of this factory building may include at least the following steps: Step 201: Upon receiving a parameter control instruction, respond to the parameter control instruction, determine the environmental control mode and mode control parameters corresponding to the current storage object, and determine the opening and closing angle range of the fan blades according to the layout of the target factory.

[0025] The environmental control mode includes a temperature control mode or a pressure control mode, and the mode control parameters include a target temperature control temperature or a target pressure control differential. The fan blades are located at the outlet of the air supply duct of the target plant.

[0026] In the embodiments described in this specification, when the server's control system receives parameter adjustment instructions sent by the terminal used by the administrator, it will generate a series of responses to the adjustment instructions. First, the control system determines the current storage object and selects the corresponding environmental control mode and mode control parameters according to the type of storage object through a preset storage information database. The environmental control mode includes temperature control mode or pressure control mode, and the mode control parameters include target temperature control temperature or target pressure control differential. When the environmental control mode is selected as temperature control mode, the mode control parameters are selected accordingly as target temperature control temperature. When the environmental control mode is selected as pressure control mode, the mode control parameters are selected accordingly as target pressure control differential. Due to different factory layouts, the storage areas of the storage objects in the factory are different, and the temperature and pressure differential of each area in the factory are different. The air blown out from the fan blades should be directed towards the storage area to prioritize the temperature or pressure control effect of the storage area. Therefore, it is necessary to determine the opening and closing angle range of the fan blades in the target factory based on the layout of the target factory. In the target factory, the fan blades are located at the outlet of the air supply duct.

[0027] As an example, the stored objects could be different types of tobacco shreds, and the target facility could be a warehouse for storing these shreds. To maintain the quality of the tobacco shreds, different types require different storage conditions. For instance, tobacco shred A needs to be stored at an ambient temperature of around 25°C to ensure its quality remains unaffected, but the pressure difference requirement within the target facility is not high. On the other hand, tobacco shred B needs to be stored at a pressure difference of around 10 Pa within the target facility to ensure its quality remains unaffected, but the temperature requirement within the target facility is not high. Therefore, before using the warehouse to store tobacco shreds, managers need to determine the environmental control mode and mode control parameters of the target facility based on the type of tobacco shreds, and then generate parameter control instructions, which are then sent to the server.

[0028] When selecting the control mode for the internal storage environment of the factory, a custom mode can also be selected. By simultaneously setting the temperature and pressure difference parameters of the internal storage environment, it is possible to meet the situation where some types of tobacco in the storage have high requirements for both temperature and pressure difference in the internal storage environment.

[0029] In one possible implementation, determining the environment control mode and mode control parameters corresponding to the current storage object includes: According to the parameter control instructions, the target type information of the current storage object is obtained, and the target type information is queried in the preset storage information database to obtain the environmental control mode and mode control parameters corresponding to the target type information.

[0030] In the embodiments of this specification, after receiving the control command, the control system first obtains the target type information of the currently stored object, and queries the target type information in the preset storage information database to find the environmental control mode and mode control parameters corresponding to the target type information in the storage information database.

[0031] The pre-set storage information database is created by administrators who, based on the characteristics of different types of tobacco and their own experience, pre-set corresponding environmental control modes and mode control parameters for each type of storage object. This data is then aggregated to form the storage information database. Through this pre-set database, the environmental control mode and mode control parameters corresponding to each type of storage object can be retrieved.

[0032] In one possible implementation, determining the opening and closing angle range of the fan blades based on the layout of the target factory building includes: Based on the layout of the target factory, the storage area of ​​the current storage object in the target factory is determined, and the opening angle range of the fan blade opening angle is determined according to the fan blade opening angle between each point in the storage area and the fan blade position of the target factory.

[0033] In the embodiments of this specification, the actual layout of the target factory where the current storage object is located is first determined, and the storable area of ​​the current storage object in the target factory is determined based on the actual layout. If the factory is large, the temperature and pressure difference at different locations within the factory will vary. The air blown from the fan blades should be directed towards the storable area to prioritize the temperature and pressure control effect of the storable area. Therefore, the air outlet angle range of the fan blades needs to be adjusted according to the different layouts of the factory. The lines connecting each point within the storable area to the fan blade position point in the target factory and the fan blade closure line can form fan blade opening and closing angles. Generally, the fan blade limit opening and closing angle range can be determined by connecting the extreme position points within the storable area to the fan blade position point and the fan blade closure line.

[0034] As an example, when the stored object is tobacco shreds, the required storage quantity for different types of tobacco shreds in actual production is different. Therefore, the required factory size for storing different types of tobacco shreds is different, resulting in different actual layouts of different factories during actual storage, which in turn affects the available storage area of ​​the stored object in the target factory.

[0035] Step 202: When the environmental control mode is the temperature control mode, the opening and closing angle of the blower fan blades is adjusted to the maximum value of the opening and closing angle range, and the air supply temperature of the blower is adjusted based on the temperature difference between the target temperature control temperature and the real-time temperature of the target factory.

[0036] The blower is located at the inlet of the air supply duct of the target factory building.

[0037] In the embodiments of this specification, when the control system selects the environmental control mode as temperature control mode according to the type of stored object, the control system will obtain the target temperature control temperature of the currently stored object. First, the opening and closing angle of the fan blades in the target factory is adjusted to the maximum value of the opening and closing angle range by a stepper motor, and the difference between the target temperature control temperature and the real-time temperature of the target factory is calculated. Based on this difference, the air supply temperature of the blowing device is adjusted.

[0038] The air supply ducts of the target factory building typically have an inlet and an outlet. The inlet connects to other main ducts, while the outlet is connected to the internal environment of the factory building. The blower is usually located at the inlet of the air supply duct, and the blower fan blades are located at the outlet.

[0039] The opening and closing angle of the fan blades in the target factory is adjusted to the maximum value of the opening and closing angle range by a stepper motor. This is to make the temperature control speed the fastest, so that the actual ambient temperature in the target factory reaches the target temperature control temperature in a short time, thereby minimizing the impact of the control time on the quality of the stored objects.

[0040] Adjusting the opening and closing angle of the blower fan blades using a stepper motor involves the following steps: First, the control system needs to set a preset angle, i.e., the specific angle the blower fan blades are expected to rotate to. Then, an angle sensor or encoder is used to monitor the current angle of the blower fan blades in real time and transmits this feedback information back to the control system. Next, the control system uses a specific control algorithm to compare the difference between the target angle and the current angle and calculates the stepper motor's required step angle. Common control algorithms include PID control and closed-loop control. The calculated step angle command is sent to the stepper motor via the motor driver. The motor driver controls the coil current of the stepper motor according to the command, causing it to rotate by the corresponding step angle. To ensure control accuracy, the control system needs to perform angle calibration periodically, achieved through a specific calibration procedure. Typically, the stepper motor is rotated to a known position, and the actual angle is determined by sensor feedback. During the control process, the control system monitors the angle feedback of the blower fan blades in real time and compares it with the preset angle. If an error exists, the control system will adjust according to the feedback information to gradually bring the blower fan blade angle closer to the preset angle.

[0041] In one possible implementation, adjusting the air supply temperature of the blower based on the temperature difference between the target temperature and the real-time temperature of the target factory building includes: The real-time temperature of the target factory building is obtained by a temperature sensor installed inside the target factory building, and the temperature difference between the target temperature control temperature and the real-time temperature is calculated. When the temperature difference is less than or equal to the preset temperature difference, the air supply temperature of the blower is adjusted to the target temperature control temperature. When the temperature difference is greater than the preset temperature difference, an excess value is calculated based on the difference between the temperature difference and the preset temperature difference. The temperature correction value corresponding to the excess value is queried in the preset temperature correction database, and the air supply temperature of the blower is adjusted to the sum of the target temperature control temperature and the temperature correction value.

[0042] In the embodiments of this specification, the real-time temperature of the target factory building is first obtained through a temperature sensor inside the target factory building. The temperature difference is calculated by subtracting the target temperature from the real-time temperature. The calculated temperature difference is then compared with a preset temperature difference value. If the temperature difference is less than or equal to the preset temperature difference value, the air supply temperature of the blower is directly adjusted to the target temperature. If the temperature difference is greater than the preset temperature difference value, due to the large temperature difference, heat transfer will occur between the internal and external environments of the factory building. Directly adjusting the air supply temperature of the blower to the target temperature would lead to a significant error in the actual temperature control result. Therefore, it is necessary to further calculate the difference between the temperature difference and the preset temperature difference value to obtain the excess value. The temperature correction value corresponding to the calculated excess value is then retrieved from a preset temperature correction database. Finally, the target temperature and the temperature correction value are added to obtain the corrected temperature, and the air supply temperature of the blower is adjusted to the corrected temperature.

[0043] As an example, the temperature regulation process of the control system can be achieved through the following steps: Temperature sensors inside the target plant collect real-time plant temperature data, generating analog signals. These analog signals are then converted into digital signals by an analog-to-digital converter. This digital signal is input to the PLC's input module. A pre-programmed PID control algorithm in the PLC calculates the corresponding control signal based on the set target temperature and the actual temperature. The PLC's output module converts the control signal into the electrical signal required by the air blower and sends it to the air blower. The air blower adjusts its temperature according to the PLC's output signal. Temperature sensors periodically measure the temperature and feed the measured values ​​back to the PLC's input module. The PLC uses these feedback values ​​to check if the actual temperature is close to the set target temperature. Based on the temperature feedback values ​​and the set target temperature, a new control signal is calculated to regulate the air blower. This process is repeated continuously to keep the actual temperature as close as possible to the target temperature.

[0044] In addition to PID control algorithms, fuzzy control algorithms can also be used in PLCs. First, the input and output variables of the fuzzy control system need to be defined. In temperature control mode, the input variables can be the actual temperature and error, and the output variable can be the control signal. Based on the characteristics of the input and output variables, fuzzy sets need to be designed. Fuzzy sets map actual physical quantities to the membership functions of fuzzy sets, usually represented by shapes such as triangles or trapezoids. The fuzzy rule base defines the relationship between the input and output variables. It consists of a series of fuzzy rules, each representing the mapping relationship between the membership degrees of the input and output variables. In the fuzzy inference stage, the membership degree of the output variable is calculated through fuzzy logic operations based on the membership degrees of the input variables and the fuzzy rule base. Commonly used fuzzy logic operations include fuzzy AND, fuzzy OR, and fuzzy NOT. The fuzzy output obtained from fuzzy inference is then converted into a specific control signal through defuzzification methods. Commonly used defuzzification methods include the maximum membership method and the weighted average method.

[0045] Real-time control is implemented in the PLC, and the control signal obtained from defuzzification is output to the actuator to adjust the air supply temperature of the blower. Based on the actual control effect, the fuzzy set, fuzzy rule base, and defuzzification method of the fuzzy control system are adjusted and optimized to improve the performance and stability of the constant temperature control.

[0046] Step 203: When the environmental control mode is the pressure control mode, determine the target opening angle of the air outlet position furthest from the air outlet position based on the air outlet position of the target factory building, adjust the opening angle of the blower fan blades to the target opening angle, and adjust the air supply speed of the blower device based on the pressure difference between the target control pressure difference and the real-time pressure difference of the target factory building and the target opening angle.

[0047] In the embodiments of this specification, when the control system selects the environmental control mode as the pressure control mode based on the type of stored object, it first determines the position of the blower blades in the target factory where the airflow direction of the blower blades is furthest from the exhaust port of the target factory. The blade angle of the blower blades at this point is then fixed, and this opening and closing angle is defined as the target opening and closing angle. Further, the pressure difference between the target control pressure difference and the real-time pressure difference in the target factory is calculated. Since the size of the opening and closing angle also affects the adjustment of the pressure difference, the airflow speed of the blower device needs to be adjusted based on the calculated pressure difference and the target opening and closing angle.

[0048] The purpose of fixing the fan blade angle at the exhaust port direction furthest from the target factory building is to prevent the air delivered by the fan blade from being directly discharged through the exhaust port, which would result in low pressure differential control efficiency inside the factory building and cause energy waste to a certain extent.

[0049] In one possible implementation, adjusting the airflow velocity of the blowing device based on the pressure difference between the target controlled pressure difference and the real-time pressure difference of the target plant and the target opening / closing angle includes: The real-time differential pressure of the target factory building is obtained by a differential pressure sensor installed inside the target factory building. The differential pressure difference is calculated based on the difference between the target control differential pressure and the real-time differential pressure. The corresponding first air supply velocity is obtained based on the differential pressure difference. The second air supply speed is determined based on the target opening and closing angle and the standard air supply angle. The air supply speed of the blower is adjusted to be the sum of the first air supply speed and the second air supply speed. The standard air supply angle is the air supply angle corresponding to the first air supply speed.

[0050] In the embodiments of this specification, the real-time differential pressure of the target factory building is obtained through a differential pressure sensor inside the target factory building. The difference between the target controlled differential pressure and the real-time differential pressure of the target factory building is calculated to obtain the differential pressure difference value. Since the differential pressure control inside the target factory building is adjusted by changing the wind speed, it is necessary to obtain the first supply air velocity corresponding to the calculated differential pressure difference value. After obtaining the first supply air velocity, the standard supply air angle of the supply fan blades at the first supply air velocity is determined. Since there is an angle difference between the standard supply air angle and the target opening angle, and the angle difference will affect the differential pressure inside the factory building, it is necessary to determine the second supply air velocity using the target opening angle and the standard supply air angle. Finally, the first supply air velocity and the second supply air velocity are added to obtain the corrected air velocity. Only the corrected air velocity can meet the differential pressure control requirements, so the supply air velocity of the blowing device is then adjusted to the corrected air velocity.

[0051] As an example, the differential pressure control process can be implemented through the following steps: A differential pressure sensor inside the target plant collects real-time plant differential pressure data, generating an analog signal. This analog signal is then converted into a digital signal by an analog-to-digital converter. This digital signal is input to the PLC's input module. A pre-programmed control algorithm in the PLC calculates the corresponding control signal based on the set target differential pressure and the actual differential pressure. The PLC's output module converts the control signal into the electrical signal required by the blower and sends it to the blower. The blower adjusts its airflow speed according to the PLC's output signal. The differential pressure sensor periodically measures the plant's internal differential pressure and feeds the measured values ​​back to the PLC's input module. The PLC uses these feedback values ​​to check if the actual differential pressure is close to the set target differential pressure. Based on the temperature feedback value and the set target differential pressure, a new control signal is calculated to adjust the blower's airflow speed. This process is repeated continuously to keep the actual differential pressure as close as possible to the target control differential pressure.

[0052] In one possible implementation, obtaining the corresponding first supply air velocity based on the pressure difference includes: The first supply air velocity corresponding to the pressure difference is obtained by comparing the pressure difference value with the preset wind speed database.

[0053] In the embodiments of this specification, after the pressure difference is calculated by difference, the first air supply speed corresponding to the corresponding blowing device is obtained by querying the preset wind speed database.

[0054] The pre-set wind speed database is created by managers who, based on the target factory layout, test the pressure difference changes corresponding to altering unit wind speeds within the target factory. This test data is then compiled to construct a pre-set wind speed database. Using this database, managers can determine the corresponding supply air speed adjustment for each pressure difference.

[0055] In one possible implementation, obtaining the corresponding second air supply velocity based on the target opening / closing angle and the standard air supply angle obtained based on the first air supply velocity includes: Calculate the difference between the target opening angle and the standard air supply angle to obtain the correction angle, where the standard air supply angle is the air supply angle corresponding to the first air supply speed; The system queries the preset differential pressure correction database for the corrected differential pressure corresponding to the corrected angle, and queries the wind speed database for the second supply wind speed corresponding to the corrected differential pressure.

[0056] In the embodiments of this specification, the difference between the target opening angle and the standard air supply angle is first calculated to obtain the correction angle. Based on the calculated correction angle, the correction pressure difference corresponding to the correction angle is obtained according to the preset pressure difference correction database. Then, the second air supply velocity corresponding to the correction pressure difference is obtained according to the previously preset wind speed database.

[0057] The preset differential pressure correction database is created by managers who test the pressure difference corresponding to changing a unit fan blade angle while keeping the supply air velocity constant in the target plant. This test data is then compiled into a preset wind speed database. Using this database, the required corrected differential pressure for each correction angle can be retrieved.

The environmental control mode includes temperature control mode or pressure control mode, and the mode control parameters include target temperature control temperature or target pressure control differential. The fan blades are set at the outlet of the air supply duct of the target plant. The first judgment module 302 is used to adjust the opening and closing angle of the blower fan blades to the maximum value of the opening and closing angle range when the environmental control mode is the temperature control mode, and adjust the air supply temperature of the blower device based on the temperature difference between the target temperature control temperature and the real-time temperature of the target factory building. The blower device is set at the air supply duct inlet of the target factory building.
