Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a parameter control system, electronic equipment, and storage medium for a pressurized building. Background Technology

[0002] High-altitude pressurized buildings are crucial facilities for coping with the low-oxygen environment at high altitudes and ensuring the physiological health of personnel. They are widely used in research stations, outposts, and residential buildings in high-altitude and cold regions. The core function of these buildings is to artificially increase the indoor oxygen partial pressure while maintaining a suitable temperature and humidity environment. In existing technologies, indoor environmental control typically involves multiple key parameters such as pressure, temperature, humidity, oxygen concentration, and carbon dioxide concentration. Mainstream control strategies generally employ traditional single-loop independent control logic, using PID algorithms to treat the aforementioned environmental parameters as independent variables, configuring dedicated sensors and actuators for closed-loop regulation. In practice, indoor pressure and gas concentration are controlled by adjusting fan speed and valve opening, independent temperature control modules are used to regulate heating or cooling equipment to maintain room temperature, and humidity is managed separately through humidification or dehumidification devices. There is a lack of deep information interaction and coordination mechanisms between these subsystems.

[0003] However, in the actual operation of pressurized buildings on plateaus, there is a problem of control imbalance caused by strong coupling of multiple parameters. This dynamic coupling and constraint conflict between multiple variables makes it easy for existing technologies to have response lag, large overshoot, and environmental parameter fluctuations that exceed the human comfort zone or even safety threshold when facing complex operating conditions.

[0020] In related technologies, high-altitude pressurized buildings are crucial facilities for coping with the low-oxygen environment at high altitudes and ensuring the physiological health of personnel. They are widely used in research stations, outposts, and residential buildings in high-altitude and cold regions. The core function of such buildings is to artificially increase the indoor oxygen partial pressure while maintaining a suitable temperature and humidity environment. In existing technologies, indoor environmental control typically involves multiple key parameters such as pressure, temperature, humidity, oxygen concentration, and carbon dioxide concentration. Mainstream control strategies generally employ traditional single-loop independent control logic, using PID algorithms to treat the aforementioned environmental parameters as independent variables, configuring dedicated sensors and actuators for closed-loop regulation. In practice, indoor pressure and gas concentration are controlled by adjusting fan speed and valve opening, independent temperature control modules are used to regulate heating or cooling equipment to maintain room temperature, and humidity is managed separately through humidification or dehumidification devices. There is a lack of deep information interaction and coordination mechanisms between these subsystems.

[0021] However, in the actual operation of pressurized buildings on plateaus, there is a problem of control imbalance caused by strong coupling of multiple parameters. This dynamic coupling and constraint conflict between multiple variables makes it easy for existing technologies to have response lag, large overshoot, and environmental parameter fluctuations that exceed the human comfort zone or even safety threshold when facing complex operating conditions. This seriously affects the operational reliability of the building and the living experience of the people.

[0022] To address the technical problems existing in related technologies, embodiments of the present invention provide a parameter control system for pressurized buildings. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of a parameter control system for a pressurized building provided in an embodiment of the present invention. The system includes: an environmental sensing module, a control calculation module, an equipment driving module, and a power supply and communication module. The environmental sensing module is used to collect first environmental index data indoors and second environmental index data outdoors of the target pressurized building, and send the first environmental index data and the second environmental index data to the control and calculation module.

[0023] The first environmental index data provided in this embodiment may include various environmental parameters such as indoor pressure, temperature, humidity, oxygen, and carbon dioxide, while the second environmental index data may include various meteorological disturbance parameters such as outdoor temperature, humidity, and atmospheric pressure.

[0024] In this embodiment, the environmental sensing module may include a micro-differential pressure sensor, a temperature and humidity sensor, an integrated oxygen and carbon gas sensor, and an outdoor meteorological sensor. Specifically, the sensors provided in this embodiment simultaneously collect data on various environmental indicators such as indoor pressure, temperature, humidity, oxygen, and carbon dioxide, as well as various meteorological disturbance parameters such as outdoor temperature, humidity, and atmospheric pressure. This provides comprehensive, synchronous, and high-precision data support for subsequent model prediction, feedforward disturbance compensation, and real-time feedback correction, thereby effectively improving the accuracy of environmental control.

[0025] It should be noted that all sensors provided in this embodiment are adaptable to extreme working conditions such as high altitude, low pressure, large temperature difference, and strong electromagnetic interference, and can ensure long-term stable sampling.

[0026] The control calculation module is used to perform multi-parameter coupled control calculation processing on the first environmental index data and the second environmental index data to obtain the control command of the target actuator when the environmental index data in the target pressurized building meets the target conditions. The target actuator includes at least one environmental control device in the target pressurized building.

[0027] In this embodiment, the control operation module provided in this embodiment may have a built-in coupled dynamics model and a constraint model predictive control algorithm. The control operation module is used to predict and optimize the first environmental index data and the second environmental index data using the coupled dynamics model, and to constrain the feasible domain boundary of the coupled dynamics model in the optimization process using the constraint model predictive control algorithm, so as to obtain the control command of the target actuator when the environmental index data of the target pressurized building meets the target conditions.

[0028] Specifically, the multi-parameter coupled control calculation processing provided in this embodiment mainly involves inputting the first environmental index data and the second environmental index data into a pre-constructed coupled dynamic model. The dynamic change trend of each parameter is obtained through model deduction. At the same time, the feasible domain boundary is constrained in the optimization process by combining the constraint model predictive control algorithm. Finally, under the premise of satisfying all constraints, the optimal control command that can make each environmental parameter stably fall within the target range is calculated, that is, the optimal control command when the target conditions are met, and then issued to the corresponding actuator to complete the adjustment.

[0029] In this embodiment, the control operation module provided may include a PLC controller and an embedded main control MCU controller. The controller may have a pre-built coupled dynamics model and constraint model predictive control algorithm built in. Thus, by using the control operation module provided in this embodiment, various control operation functions can be completed, including real-time data parsing, system state updating, dynamic prediction of future parameters, rolling optimization solution, output of control instructions for actuators, fault identification and feedback correction functions. It is the core operation carrier for realizing multi-parameter coupling and decoupling, and coordinated optimal control.

[0030] The device driver module is used to receive the control command sent by the control calculation module, and drive the target actuator to perform the corresponding execution action according to the control command.

[0031] In this embodiment, the device drive module is the environmental control execution carrier of the target pressurized building. It has no carbon dioxide adsorption, desorption, or internal circulation purification hardware and relies entirely on ventilation replacement to remove carbon dioxide.

[0032] Specifically, the device drive module provided in this embodiment may include a blower, an exhaust valve, an electric heating module, and a dehumidification module; The air supply fan is used to perform a first operation according to the control command, the first operation including indoor pressurization, oxygen replenishment, and outdoor fresh air dilution of carbon dioxide; the exhaust valve is used to perform a second operation according to the control command, the second operation including adjusting the indoor exhaust air replacement flow rate; the electric heating module is used to perform a third operation according to the control command, the third operation including adjusting the heating power; the dehumidification module is used to perform a fourth operation according to the control command, the fourth operation including adjusting the dehumidification power.

[0033] In this embodiment, the air supply fan can adopt a stepless frequency conversion adjustment mode, thereby accurately controlling the molar flow rate of the fresh air supply and realizing the functions of indoor pressurization, oxygen replenishment, and dilution of carbon dioxide by outdoor fresh air; the exhaust valve can support continuous opening adjustment from 0 to 100%, thereby accurately regulating the indoor exhaust air replacement flow rate, and is the core execution component for carbon dioxide ventilation removal and indoor pressure relief and balancing; the electric heating module has continuously adjustable power characteristics, which can compensate for the heat exchange loss caused by the low temperature of fresh air at high altitudes in real time, thereby effectively stabilizing the indoor temperature range; the dehumidification module supports adaptive power adjustment, which can match the alternating dry and wet conditions of high altitudes day and night, thereby accurately stabilizing the indoor air humidity.

[0034] The power supply and communication module is used to provide working power to the device drive module and to complete data transmission between the modules.

[0035] The power supply and communication module provided in this embodiment may include separately arranged high-voltage and low-voltage structures. The high-voltage structure supplies power to the device drive module, while the low-voltage structure transmits signals and control commands to each module. By adopting a structure that separates high-voltage and low-voltage components, complex electromagnetic interference at high altitudes can be effectively avoided, ensuring high-speed iteration of algorithms in the control and calculation module, synchronous data transmission, and real-time response to execution commands, thereby meeting the requirements for long-term continuous and stable system operation.

[0036] Thus, by employing this embodiment of the invention, indoor and outdoor environmental index data are synchronously collected through the environmental sensing module. Multi-parameter coupling calculations are then performed using the coupled dynamics model and constraint model predictive control algorithm built into the control calculation module. After obtaining the optimal control command, the device drive module completes the corresponding adjustment action. This effectively solves the control imbalance problem caused by multi-parameter coupling interference in traditional single-loop independent control. Compared to traditional single-loop independent control schemes, this embodiment of the invention can predict and intervene in environmental disturbances caused by meteorological changes in advance, significantly improving the system's anti-interference capability. It can ensure that various indoor environmental parameters of pressurized buildings are maintained stably within the preset comfortable and safe range for a long period, effectively improving the operational reliability of pressurized buildings and the living experience of residents.

[0037] As an optional embodiment, in order to obtain the coupled dynamics model and constraint model predictive control algorithm to complete the multi-parameter coupled control calculation and processing of environmental index data, please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is another structural schematic diagram of the parameter control system for a pressurized building provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the parameter control system for the pressurized building provided in this embodiment may further include: an acquisition module and a construction module; The acquisition module is used to acquire the building information of the target pressurized building and the equipment information of the environmental control equipment. The building information includes the spatial volume of the target pressurized building and the heat transfer coefficient of the building envelope. The equipment information includes the amplitude constraint information and execution increment constraint information of the operating parameters of the environmental control equipment. The construction module is used to construct a coupled dynamic model for simulation and control of the target pressurized building based on the building information and the equipment information.

[0038] In this embodiment, regarding building information, the length, width, and height data of the target pressurized building can be extracted from the architectural design drawings to calculate the spatial volume. Combined with the thermal conductivity parameters and thickness of the wall materials, the heat transfer coefficient of the building envelope can be calculated. Regarding equipment information, this embodiment can obtain the rated power and range of the environmental control equipment by acquiring its equipment information, or access the controller's internal registers through the equipment communication interface to determine amplitude and incremental limit parameters, thereby obtaining the amplitude constraint information and execution incremental constraint information of the operating parameters of each environmental control device.

[0039] It should be noted that the amplitude constraint information of the operating parameters provided in this embodiment defines the limit range of the output physical quantities of various environmental control devices, which may include indicators such as the maximum allowable speed or air volume of the intake and exhaust fans, the maximum power output of the heater, and the maximum dehumidification capacity of the dehumidifier. Thus, by executing the incremental constraint information, the adjustment range of the environmental control devices per unit time can be limited, such as the maximum allowable frequency change of the fan per second and the maximum allowable change in valve opening per second. This allows the construction of a constraint model predictive control algorithm. Using this constraint model predictive control algorithm can avoid sudden parameter changes caused by excessive device movement, ensuring the stability of the indoor environment and the comfort of personnel.

[0040] After obtaining building and equipment information, this embodiment can utilize the acquired building and equipment information to establish a coupled dynamics model corresponding to the target pressurized building. Specifically, the coupled dynamics model provided in this embodiment is mainly used to describe the dynamic coupling relationship between indoor environmental indicators such as oxygen, carbon dioxide, water vapor, temperature, and pressure. Numerical simulation is used to predict the evolution trend of the environmental state, so that subsequent optimization control can be performed in the model to ensure the positive pressure safety of the high-altitude pressurized building and the stable operation of the equipment.

[0041] The specific construction logic in the model building process can be as follows: First, establish the gas component equilibrium differential equations for oxygen, nitrogen, carbon dioxide, and water vapor based on the law of conservation of mass; then, establish the temperature dynamic differential equations to characterize the dynamic evolution of indoor temperature based on the law of conservation of energy; subsequently, establish dynamic coupling equations between temperature and humidity, and between temperature and pressure, based on the ideal gas law, the gas component equilibrium differential equations, and the temperature dynamic differential equations; finally, determine the feasible domain boundaries of the above dynamic coupling equations in the numerical solution or optimization process based on amplitude constraint information and incremental constraint information. In this way, by transforming the physical properties of the building and the execution capabilities of the equipment into model parameters and constraints, the constructed coupled dynamic model can accurately reproduce the correlation between the thermodynamic characteristics of the pressurized building interior and the operating parameters of the environmental control equipment.

[0042] Specifically, to complete the construction of the coupled dynamics model, please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of a construction module provided in an embodiment of the present invention, such as... Figure 3 As shown, the building module provided in this embodiment may include a first building unit, a second building unit, a third building unit, a fourth building unit, and a combination unit; The first building unit is used to build a gas component mass conservation model based on the indoor gas component balance and building air leakage disturbance.

[0043] In this embodiment, the gas component mass conservation model provided is mainly used to describe the dynamic changes of various gas components in the target pressurized building under the combined effects of ventilation supply, exhaust, human metabolic consumption or generation, and building air leakage loss. The construction of the gas component conservation model provided in this embodiment requires determining the molar number of each gas component (including oxygen, nitrogen, carbon dioxide, and water vapor) in the room, and determining input parameters such as fresh air supply, exhaust volume, building air leakage, and human metabolic productivity, thereby establishing differential equations for the change of the molar number of each gas component over time.

[0044] As an optional embodiment, the first building unit provided in this embodiment is specifically used to: determine the gas component balance equation of the target gas based on the component balance relationship of carbon dioxide, water vapor and indoor target gas generated by indoor personnel, wherein the target gas includes oxygen, nitrogen, carbon dioxide and water vapor; and construct the gas component mass conservation model of the target pressurized building based on the gas component balance equation, the air supply volume and exhaust volume of the environmental control equipment in the target pressurized building and the air leakage volume of the target pressurized building.

[0045] For example, regarding the oxygen component balance, since oxygen is determined by the amount of fresh air brought in, the amount of exhaust air discharged, and the amount consumed by human respiration, the oxygen component balance equation can be expressed as follows:

[0046] In the formula, This indicates the number of moles of oxygen in the room, expressed in mol. This indicates the inlet air molar flow rate, in units of mol / s; Indicates the mole fraction of oxygen in the intake air; This indicates the exhaust molar flow rate, with units of mol / s. Indicates the mole fraction of oxygen in the room; Indicates indoor carbon dioxide production rate, in mol / s; The respiratory quotient (RSQ) is typically between 0.83 and 0.85.

[0047] The oxygen component balance equation described above enables the gas component mass conservation model provided in this embodiment to not only calculate changes in oxygen concentration, but also to correlate the coupling relationship between oxygen consumption and carbon dioxide generation based on the human respiratory quotient.

[0048] For nitrogen component balance, since nitrogen is an inert component, it is neither generated nor consumed indoors, and is only affected by ventilation and air leakage. Therefore, the nitrogen component balance equation can be expressed as follows:

[0049] In the formula, This indicates the number of moles of nitrogen gas in the room, expressed in mol. Indicates the mole fraction of nitrogen in the intake air; This indicates the mole fraction of nitrogen in the room.

[0050] For the carbon dioxide component balance, since the indoor carbon dioxide source is generated by human metabolism, the removal method is only exhaust ventilation replacement, without adsorption purification devices. That is, fresh air brings in low-concentration CO2 for dilution, and exhaust air continuously carries out high-concentration CO2 from the room. Therefore, the carbon dioxide component balance equation can be expressed as follows:

[0051] In the formula, This indicates the number of moles of carbon dioxide in the room, expressed in mol. Indicates the mole fraction of carbon dioxide in the intake air; This indicates the mole fraction of carbon dioxide in the room.

[0052] For the water vapor composition balance, since the amount of water vapor is determined by the amount of fresh air brought in, the amount of exhaust air discharged, and the amount generated by the human body, the water vapor composition balance equation can be expressed as follows:

[0053] In the formula, This indicates the number of moles of water vapor in the room, expressed in mol. Indicates the mole fraction of water vapor in the intake air; Indicates the mole fraction of indoor water vapor; This indicates the rate at which water vapor is produced by the human body, expressed in mol / s.

[0054] Thus, based on the component balance equations of each gas in the above embodiments, the total mole balance equation of the gas in the pressurized building can be determined, that is, a gas component mass conservation model can be constructed, which can be expressed as follows:

[0055] In the formula, This indicates the molar flow rate of indoor air leakage, expressed in mol / s. , This represents the number of moles of the i-th gas component.

[0056] It should be noted that the air volume provided in this embodiment is... The system actively manipulates variables, determined by the fan's operating parameters; exhaust volume. Driven by the pressure difference between indoors and outdoors, the flow rate can be calculated using the orifice plate flow formula:

[0057] In the formula, Indicates the orifice flow coefficient; Indicates the circulation area; P represents gas density; P represents indoor pressure. Indicates the drag coefficient; This represents the average molar mass of the gas mixture.

[0058] It should be noted that indoor occupants are the core endogenous disturbance in pressurized buildings, continuously generating carbon dioxide, water vapor, and heat, which directly affect indoor air quality and temperature and humidity. Therefore, this embodiment can determine the amount of carbon dioxide and water vapor generated by constructing a carbon dioxide and water vapor generation model.

[0059] Specifically, CO2 production rate O2 consumption rate Water vapor production rate ; In the formula, N represents the number of people staying indoors; It represents the molar yield of CO2 per unit time for a single person and is positively correlated with the number of residents and the intensity of individual activity. This represents the molar yield of water vapor per unit time for a single person, which is related to ambient temperature and humidity, as well as activity intensity.

[0060] Thus, the gas component mass conservation model provided in this embodiment can describe the evolution of indoor oxygen, nitrogen, carbon dioxide, and water vapor over time under the influence of supply air volume, exhaust air volume, and leakage air volume. This allows for accurate prediction of the dynamic changes in indoor gas concentrations under different ventilation strategies, providing a precise basis for subsequent environmental control strategies.

[0061] The second building unit is used to build a temperature and energy balance model based on the heat transfer coefficient of the building envelope, the change of internal energy in the room, and the disturbance of indoor heat sources.

[0062] In this embodiment, the temperature energy balance model provided is mainly used to characterize the dynamic evolution of indoor temperature in the target pressurized building under the influence of heat conduction, heat exchange and internal heat source disturbance. Specifically, the indoor system is regarded as an open system with energy exchange: the rate of change of indoor energy is equal to the sum of the enthalpy brought in by fresh air, the enthalpy carried away by exhaust air, the heat transfer loss through the building envelope and the heat dissipation of indoor heat sources (including heat dissipation from personnel and equipment).

[0063] As an optional embodiment, the second building unit provided in this embodiment is specifically used for: calculating the first heat dissipation of the building envelope based on the heat transfer coefficient of the building envelope and the temperature difference between the inside and outside of the target pressurized building; calculating the second heat dissipation of the target pressurized building based on the heat dissipation of the electromechanical equipment and the heat dissipation of the occupants inside the target pressurized building; and constructing a temperature energy balance model of the target pressurized building based on the enthalpy increase and enthalpy loss of the environmental control equipment inside the target pressurized building, the first heat dissipation, and the second heat dissipation.

[0064] In this embodiment, to quantify the process of indoor energy change rate, this embodiment can be described using an open-system energy balance differential equation, specifically expressed as:

[0065]

[0066] in, This represents the internal energy of indoor air. This indicates the enthalpy flow rate of the incoming fresh air. This indicates the specific heat capacity of fresh air at constant pressure. Indicates the temperature of the fresh air; This indicates the enthalpy flow rate carried away by the exhaust air. This indicates the specific heat capacity of the indoor gas mixture at constant pressure. Indicates the temperature difference between indoors and outdoors; This represents the heat loss through the building envelope, also known as the primary heat loss; UA represents the heat transfer coefficient of the building envelope. Indicates the outdoor temperature; This represents the total indoor heat source disturbance power, specifically the sum of the heat dissipation rate of personnel and the heat dissipation rate of equipment, also known as the second heat dissipation.

[0067] After determining the open-system energy balance differential equation, this embodiment can expand the open-system energy balance differential equation and simultaneously solve the component mass change coupling terms to obtain the fully coupled solution equation for indoor temperature. This allows the construction of a temperature and energy balance model for the target pressurized building's interior, specifically represented as follows:

[0068] Among them, it means This represents the specific heat capacity at constant volume for the i-th gas; This represents the number of moles of the i-th gas component.

[0069] Thus, by using the fully coupled indoor temperature solution equation provided in this embodiment, the multiple coupling relationships between temperature changes and ventilation flow, component changes, indoor and outdoor temperature differences, indoor heat sources, and air leakage losses unique to pressurized buildings can be determined. This enables the temperature energy balance model provided in this embodiment to accurately depict the dynamic evolution of indoor temperature under the disturbance of multiple factors, providing an accurate basis for predicting temperature changes for subsequent environmental control.

[0070] The third building unit is used to construct a pressure-coupled dynamic model based on the space volume, the heat transfer coefficient of the enclosure structure, and the ideal gas law.

[0071] In this embodiment, the pressure coupling dynamics model provided is mainly used to reflect the coupling relationship between the indoor pressure of the target pressurized building and the total amount of gas, temperature and heat transfer characteristics of the building envelope. Specifically, by combining the ideal gas law and the mass and energy conservation equations, the differential relationship of pressure changing with time is derived, thereby constructing the pressure coupling dynamics model.

[0072] As an optional embodiment, the third building unit provided in this embodiment is specifically used for: determining the first pressure dynamic differential equation of all gases inside the target pressurized building based on the space volume and the ideal gas law; calculating the first heat dissipation of the building envelope based on the heat transfer coefficient of the building envelope and the temperature difference between the inside and outside of the target pressurized building; and constructing a pressure coupling dynamic model inside the target pressurized building based on the first pressure dynamic differential equation and the first heat dissipation.

[0073] The ideal gas law provided in this embodiment is as follows: , For indoor pressure, This represents the total number of moles of gas in the room. Let be the ideal gas constant. Indoor thermodynamic temperature, For spatial volume.

[0074] Specifically, by combining the ideal gas law with the mass conservation and energy balance equations provided in the above embodiments, i.e., simultaneously solving the total mole number change rate equation... and rate of temperature change From the expression, we can obtain the first dynamic differential equation of pressure:

[0075] in, The total number of moles of indoor gas, i.e., the number of moles of each gas component ( , , , ); Indoor thermodynamic temperature; The rate of change of temperature over time; The rate of change of the total number of moles over time; It is the ideal gas constant; For spatial volume.

[0076] Thus, by using the first pressure dynamic differential equation provided in this embodiment, the coupling relationship between changes in indoor pressure, temperature, and total gas volume can be determined.

[0077] As an optional embodiment, to improve the accuracy of model predictions, this embodiment can also add the correction effect of the first heat dissipation of the building envelope on the temperature-pressure relationship. By introducing a heat transfer coefficient term, an engineering correction model between the pressure rise rate and temperature rise is derived, thereby constructing a pressure-coupled dynamic model. Specifically, the model is shown below:

[0078] In the formula, It represents the rate of change of temperature with pressure and is used to describe the thermodynamic effects during the pressurization process; Indicates the specific heat ratio of a gas; Indicates the intake air temperature; Indicates the indoor thermodynamic temperature; Indicates indoor pressure; Indicates the outdoor ambient temperature; This represents the molar specific heat capacity at constant pressure of a gas. Indicates the heat transfer coefficient of the building envelope; Indicates volume of space; Represents the ideal gas constant; This indicates the rate of pressure change.

[0079] Thus, by using the pressure coupling dynamics model provided in this embodiment, the pressure change trend under any control action can be calculated based on building physical parameters (such as volume and heat transfer coefficient) and real-time environmental conditions. This allows the indoor pressure change rate to be limited to a pre-set human safety parameter constraint, such as 0.5 kPa / s, thereby avoiding the impact of high-altitude pressure difference and ear discomfort.

[0080] The fourth building unit is used to build a humidity dynamics model based on the space volume, the water vapor partial pressure equation, and the saturated vapor pressure equation.

[0081] In this embodiment, the humidity dynamics model provided is mainly used to calculate the dynamic changes of relative humidity in the target pressurized building and to describe its coupling relationship with temperature and water vapor component concentration. Specifically, the relative humidity is determined by calculating the water vapor partial pressure and combining it with the saturated vapor pressure at the current temperature.

[0082] As an optional embodiment, the fourth building unit provided in this embodiment is specifically used to: determine the second pressure dynamic differential equation of water vapor in the target pressurized building based on the space volume and the ideal gas law; and construct a humidity dynamic model of the target pressurized building based on the second pressure dynamic differential equation, the saturated vapor pressure equation, and the relative humidity definition equation.

[0083] In this embodiment, the water vapor partial pressure equation, also known as the second pressure dynamic differential equation, can be determined based on the ideal gas law, as shown below:

[0084] in, It is the partial pressure of water vapor; This represents the number of moles of water vapor in the room.

[0085] Optionally, the saturated vapor pressure equation provided in this embodiment can be fitted using the Magnus formula to fit the relationship between saturated vapor pressure and temperature. Specifically, the formula can be:

[0086] In the formula, Indicates temperature The saturated water vapor pressure below Indoor thermodynamic temperature

[0087] In this embodiment, after obtaining the second pressure dynamic differential equation and the saturated vapor pressure equation, the relative humidity under the current state can be calculated according to the definition of relative humidity. Humidity dynamics model.

[0088] Thus, by using the humidity dynamics model provided in this embodiment of the invention, the nonlinear coupling relationship between humidity and the total amount of indoor water vapor and temperature can be determined. As temperature increases, saturated vapor pressure rises and relative humidity decreases, enabling the model to accurately predict the trend of relative humidity changes during pressurization or heating, thus effectively improving the model's prediction accuracy.

[0089] The combined unit is used to combine the gas component mass conservation model, the temperature energy balance model, the pressure coupling dynamics model, and the humidity dynamics model to obtain the coupling dynamics model corresponding to the target pressurized building.

[0090] After obtaining the multiple models constructed in the above embodiments, these independent models can be combined and integrated to form a complete coupled dynamic model corresponding to the target pressurized building, thereby realizing the simulation and control of multi-parameter targets (five-dimensional parameters of pressure, temperature, humidity, oxygen, and carbon dioxide).

[0091] Thus, the coupled dynamics model provided by the embodiments of the present invention can accurately describe the dynamic changes of environmental index data of the target pressurized building under the influence of human metabolic disturbances, environmental meteorological disturbances and equipment control inputs. This allows for accurate prediction of the changing trends of environmental indexes under different control strategies, facilitating the optimization of subsequent control strategies. At the same time, it can ensure that the environmental parameters within the pressurized building are always maintained within the range that meets the requirements of human comfort and health, avoiding the problem of parameters exceeding the standard.

[0092] Optionally, this embodiment can also employ a real-time sampling feedback correction mechanism to correct the predicted state at the next moment by using the deviation between the actual operating parameters and the model prediction parameters. This can effectively offset the control errors caused by high-altitude wind leakage disturbances, sudden weather changes, and model mismatch, thereby improving the system's anti-disturbance capability and long-term steady-state accuracy.

[0093] In some embodiments, to adapt to the discrete iterative computation requirements of industrial controllers, this embodiment can use the steady-state operating point Taylor first-order linearization method to complete the linearization of the nonlinear model, and obtain an incremental state-space prediction model by zero-order preserved discretization. Specifically, this incremental state-space prediction model can be:

[0094] In the formula, X represents the state variable input to the model. U represents the control variable in the model, that is, the operating parameters of the environmental control equipment. , For the heater's operating parameters, such as heating power, Y represents the dehumidifier's operating parameters, such as dehumidification power; Y represents the model's output variable. , These are the concentrations of oxygen and carbon dioxide, respectively. , , , These represent the discrete system state matrix, discrete control input matrix, discrete disturbance input matrix, and discrete observation output matrix, respectively.

[0095] Thus, through linearization and discretization, the nonlinear coupled dynamics model can be transformed into a linear incremental model that is easy to design for controllers, thereby reducing the computational complexity of solving the control strategy and meeting the computational performance requirements of real-time control.

[0096] As an optional embodiment, a dual-objective optimal function for tracking accuracy and control energy consumption can also be constructed. This function can be used to minimize both the control accuracy of environmental parameters and the operating energy consumption during the optimization process. Specifically, the dual-objective optimal function can be expressed as:

[0097] in, The expected model output variables are represented by k, where k is the discrete sampling time and k+1 is the next sampling time. Q is the output error weight matrix used to adjust indoor pressure and carbon dioxide concentration, and R is the control increment weight matrix used to constrain the action amplitude of environmental control equipment. The Q and R weight matrices can be set according to actual control requirements.

[0098] In this embodiment, the output error weight matrix can prioritize ensuring the control accuracy of indoor pressure and carbon dioxide concentration, and the control incremental weight matrix can constrain the action range of environmental control equipment, thereby achieving a balance between the dual objectives of high-precision parameter tracking and optimal system operating energy consumption.

[0099] Thus, based on the dual-objective optimal function provided in this embodiment, combined with the above-mentioned incremental state-space model, the optimal control action increment ΔU(k) ​​at the current moment can be obtained by rolling solution. Based on this control action increment, the control quantity acting on the environmental control device can be determined so that the device drive module can complete the corresponding regulation action and realize the coordinated and precise regulation of multiple parameters.

[0100] In summary, this invention provides a parameter control system for a pressurized building, comprising: an environmental sensing module, a control calculation module, an equipment driving module, and a power supply and communication module. The environmental sensing module collects first environmental index data indoors and second environmental index data outdoors of the target pressurized building, and sends the first and second environmental index data to the control calculation module. The control calculation module performs multi-parameter coupled control calculation processing on the first and second environmental index data to obtain a control command for a target actuator that ensures the environmental index data indoors of the target pressurized building meets target conditions. The target actuator includes at least one environmental control device in the target pressurized building. The equipment driving module receives the control command sent by the control calculation module and drives the target actuator to perform corresponding actions according to the control command. The power supply and communication module provides power to the equipment driving module and completes data transmission between the modules.

[0101] By employing the embodiments of the present invention, the following beneficial effects can be achieved: 1. Solve the problem of multi-parameter coupling interference in traditional single-loop control; 2. By achieving multi-objective synergistic optimization through rolling optimization, the contradiction between "carbon control and pressure loss, and pressure stabilization and temperature loss" can be resolved. 3. It has feedforward prediction and intervention capabilities and strong resistance to interference from personnel disturbances and meteorological disturbances; 4. The entire process is equipped with physical constraint control to ensure positive pressure safety of high-altitude buildings, stable equipment operation, and optimal energy consumption.
