Abstract
Description
Technical Field
[0001] This invention relates to the field of ecological environment regulation technology, specifically an integrated system for forest climate regulation and pollutant purification. Background Technology
[0002] With the increasing demand for ecological environment governance and regional microclimate regulation, air quality regulation and climate control in forest environments have gradually become important research directions in the field of environmental engineering. Current technologies for air conditioning in forest environments typically employ particulate matter filtration devices, volatile organic compound adsorption or catalytic treatment devices, and independent temperature and humidity control devices for separate processing. Air purification and climate regulation are achieved through the combination of multiple functional modules. Related systems generally implement sub-control based on a single environmental indicator or a small number of indicators. Each processing module operates independently according to its own control logic, while the overall system achieves coordination through simple start-stop linkage or sequential control.
[0003] The aforementioned technical solutions have significant limitations in practical applications. Particulate pollution control, volatile organic compound (VOC) treatment, and temperature and humidity regulation typically employ independent control strategies. Various environmental parameters lack a unified characterization method, and it is difficult to establish a unified quantitative correlation between different treatment objectives. This results in the inability to coordinate and schedule the coupling relationships between multiple environmental factors within a single control framework. When particulate pollution load, gaseous pollution load, and temperature and humidity load change simultaneously, existing systems struggle to establish a unified load evaluation basis, easily leading to independent adjustments by each treatment module and inconsistent treatment rhythms. This, in turn, causes imbalances in the allocation of treatment resources and insufficient operational coordination. Summary of the Invention

[0009] Preferably, the intake phase in step S5 is used to deliver air into the processing path. The stagnation-diffusion phase is used to pause mainstream propulsion to allow pollutants to diffuse into porous and biologically active regions. The reverse release phase is used to allow air to flow in the opposite direction to the inhalation phase in order to expel accumulated moisture and residual pollutants.
[0010] Preferably, the central control unit switches the system operating mode according to the dominance of particulate pollution load, volatile organic compound pollution load, and thermal and humidity regulation load. The operating modes include particle priority mode, volatile organic compound mineralization priority mode, heat and humidity regulation priority mode, self-regeneration and recovery mode, and conservation and maintenance mode.
[0011] Preferably, in the particulate-first mode, the proportion of particulate matter diversion along the dominant path is increased and the duration of the stagnant diffusion phase is shortened; Under the volatile organic compound (VOC) mineralization priority mode, increase the proportion of VOC-dominant pathway diversion and prolong the duration of the stagnation-diffusion phase; In the heat and humidity regulation priority mode, the proportion of diversion in the dominant heat and humidity regulation pathway is increased and the continuous over-humidity of the leaf surface is limited.

[0015] This invention provides an integrated system for forest climate regulation and pollutant purification. It offers the following beneficial effects: 1. This invention constructs a control mechanism based on unified multi-load modeling, which incorporates particulate pollution status, volatile organic compound pollution status, and thermal and humid environmental status into the same control system. By using a unified load characterization method, it achieves common-source modeling and coordinated scheduling of different environmental elements, solving the problem of separate control of multiple environmental factors and dispersed control logic in existing systems.

This allows different types of environmental regulation tasks to be spatially separated and coordinated in control.
[0017] 3. The present invention constructs a phased operation mechanism, which causes air to sequentially go through an intake phase, a stagnant diffusion phase and a reverse release phase in the processing path. By switching between phases, the contact mode and mass transfer state between air and the processing medium are changed, breaking through the continuous unidirectional flow processing mode and realizing time-sharing control of the transmission process and the diffusion process, thereby improving the mass transfer conditions and state equilibrium process inside the processing medium.

By identifying the dominant relationship of different environmental loads, it realizes the automatic switching of particle priority mode, volatile organic compound mineralization priority mode and thermal and humidity regulation priority mode, so that the system operation strategy can be adjusted with the change of environmental conditions, avoiding the problem of processing resource misallocation caused by fixed operation strategy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see the appendix Figure 1 To be continued Figure 6 This invention provides an integrated system for forest climate regulation and pollutant purification, comprising: The system includes a status sensing unit, a diversion execution unit, a processing execution unit, an exhaust / gas supply execution unit, a regeneration execution unit, and a central control unit. The state sensing unit is used to collect particulate matter concentration, volatile organic compound concentration, carbon dioxide concentration, nitrogen oxide concentration, ozone concentration, inlet air temperature, inlet air relative humidity, pressure difference, composite matrix volume moisture content, and leaf surface moisture. The diversion execution unit is used to distribute the air to be processed into at least two processing paths; The processing execution unit is used to purify pollutants and regulate the climate of air entering different processing paths; The air supply and exhaust actuator is used to drive the air to flow in each processing path; The regeneration execution unit is used to perform condensation dehumidification and state restoration of the processing execution unit when preset conditions are met; The central control unit is connected to the status sensing unit, the diversion execution unit, the exhaust / supply execution unit, and the regeneration execution unit, respectively, and is used for: The air to be treated is decoupled and distributed between at least two treatment paths based on particulate pollution load, volatile organic compound pollution load, and thermal and humidity regulation load. The control unit for supplying and exhausting air causes the air to run cyclically through the intake phase, the stagnant diffusion phase, and the reverse release phase in each processing path. When the preset triggering conditions are met, the control regeneration execution unit starts dew point swing self-regeneration.
[0022] Specifically, the integrated control system for forest climate regulation and pollutant purification includes a status sensing unit, a diversion execution unit, a treatment execution unit, an exhaust and regeneration execution unit, and a central control unit. These units are connected via electrical connections and control signals to form a complete control system.
[0023] The status sensing unit continuously monitors the system's operating status and outputs monitoring data to the central control unit.

[0024] The flow splitter unit is connected to the intake passage and is used to adjust the intake flow of each processing path according to the flow split ratio issued by the central control unit. The flow splitter unit includes adjustable flow splitting components, each corresponding to the particulate matter-dominated path, the volatile organic compound-dominated path, and the temperature and humidity regulation-dominated path, respectively.
[0025] Processing units are installed on each processing path to purify pollutants and regulate the climate of the air entering the corresponding path. The particulate matter-dominated path is used to retain particulate pollutants, the volatile organic compound-dominated path is used to convert volatile organic compounds, and the temperature and humidity regulation-dominated path is used to regulate the air temperature and humidity.
[0026] Each air supply and exhaust actuator is connected to a different processing path and drives the air to flow within that path. Under the control of the central control unit, the air supply and exhaust actuators establish forward flow, stop driving, and reverse flow states to achieve phased operation of each processing path.
[0027] The regeneration execution unit is connected to the processing execution unit and is used to perform dew point swing self-regeneration under the control of the central control unit. The regeneration execution unit includes a regeneration flow path and a condensate treatment branch. The regeneration flow path is used to create a condensation environment, and the condensate treatment branch is used to collect and discharge condensate.
[0028] The central control unit is connected to the status sensing unit, the diversion execution unit, the exhaust / supply execution unit, and the regeneration execution unit. It receives monitoring data from the status sensing unit, generates diversion ratios, stage operating parameters, and regeneration control commands, and outputs control signals to the corresponding execution units. The central control unit also performs operation mode switching, self-regeneration trigger determination, exit condition determination, and adaptive adjustment control.
[0029] Each unit operates collaboratively under the unified scheduling of the central control unit, enabling the distribution of air among different treatment paths, the flow of air in each treatment path in a phased manner, and the execution of dew point swing self-regeneration when preset conditions are met, thereby realizing the integrated control of forest climate regulation and pollutant purification.
[0030] The integrated control method for forest climate regulation and pollutant purification, applied to the aforementioned integrated control system for forest climate regulation and pollutant purification, is executed by the central control unit and includes: S1. Collect particulate matter concentration, volatile organic compound concentration, carbon dioxide concentration, nitrogen oxide concentration, ozone concentration, inlet air temperature, inlet air relative humidity, pressure difference, composite matrix volume moisture content, and leaf surface moisture. S2. Calculate the particulate pollution load, volatile organic compound pollution load, and thermal and humidity regulation load based on the collected data; S3.

S7. When the exit conditions are met in the recovery state, stop the dew point swing self-regeneration and resume normal operation.
[0031] Specifically, the integrated control method for forest climate regulation and pollutant purification is applied to the aforementioned integrated control system for forest climate regulation and pollutant purification, and is executed by the central control unit.
[0032] The central control unit first receives monitoring data from the status sensing unit, including particulate matter concentration, volatile organic compound concentration, carbon dioxide concentration, nitrogen oxide concentration, ozone concentration, inlet air temperature, inlet air relative humidity, pressure difference, composite matrix volume moisture content, leaf surface moisture, and volatile organic compound storage, and then completes data verification and unified processing.
[0033] The central control unit calculates particulate pollution load, volatile organic compound (VOC) pollution load, and thermal and humidity regulation load based on monitoring data, and determines the diversion ratios of particulate matter, VOCs, and thermal and humidity regulation based on these loads.
[0034] The central control unit generates the target flow rate for each processing path according to the diversion ratio and outputs a flow distribution control signal to the diversion execution unit so that the air to be processed enters the corresponding processing path according to the diversion ratio.
[0035] The central control unit controls the air supply and exhaust actuators, causing air to sequentially pass through the intake phase, stagnant diffusion phase, and reverse release phase in each processing path. The intake phase is used to supply air to the processing actuators, the stagnant diffusion phase is used to stop the external drive, and the reverse release phase is used to discharge the accumulated gas in the processing actuators.
[0036] The central control unit continuously monitors the differential pressure, the volumetric moisture content of the composite substrate, the leaf surface humidity, and the volatile organic compound (VOC) reserves, and determines whether to initiate dew point oscillation self-regeneration based on preset trigger conditions. When the trigger conditions are met, the central control unit switches the system operating mode and outputs regeneration control commands to the regeneration execution unit.
[0037] During the dew point swing self-regeneration process, the central control unit continuously monitors the system's operating status and terminates the dew point swing self-regeneration when the exit conditions are met, restoring the system to normal operating mode.
[0038] During system operation, the central control unit adaptively adjusts the diversion ratio and the runtime of each stage based on historical operating data, and uses the adjustment results for subsequent control cycles.
[0039] Furthermore, in step S2, the particulate pollution load is determined by the particulate matter concentration, the volatile organic compound pollution load is determined by the volatile organic compound concentration, nitrogen oxide concentration, and ozone concentration, and the heat and humidity regulation load is determined by the inlet air temperature, inlet air relative humidity, composite matrix volume moisture content, and leaf surface humidity.
[0040] Specifically, the central control unit determines the particulate pollution load, volatile organic compound (VOC) pollution load, and thermal humidity control load based on data collected by the state sensing unit, and generates control parameters for the diversion execution unit, exhaust gas supply execution unit, and regeneration execution unit based on these parameters. To ensure consistency in parameter definitions, this embodiment uses... To represent particulate matter concentration, in Indicates the concentration of volatile organic compounds, in... To indicate carbon dioxide concentration, in Indicating nitrogen oxide concentration, in Ozone concentration is expressed in terms of... Indicates intake air temperature, in Indicates the relative humidity of the intake air, in This indicates the pressure difference between the inlet and outlet of the processing unit, in order to Indicates the volumetric moisture content of the composite matrix, in terms of Indicating leaf surface moisture, in This indicates the reserves of volatile organic compounds.
[0041] The central control unit first performs time synchronization, validity verification, and dimensional standardization on each monitoring parameter, and then forms a state vector for control calculations. Particulate pollution load, volatile organic compound (VOC) pollution load, and thermal and humidity regulation load are denoted as follows: and The particulate pollution load is determined by particulate matter concentration and pressure difference; the volatile organic compound (VOC) pollution load is determined by VOC concentration, nitrogen oxide concentration, ozone concentration, and VOC storage; and the thermo-humidity regulation load is determined by inlet air temperature, inlet air relative humidity, composite substrate volumetric moisture content, and leaf surface humidity. All three load categories are constructed using a unified weighted average method. ; ; ; in, , and These represent the normalized values of the corresponding parameters, k1 to k. 10 These are preset weighting coefficients.
[0042] After obtaining the three types of loads, the central control unit further determined the dominant factors of particulate pollution. Volatile organic compounds are the dominant factor. and thermo-humidity dominant factors The three dominant factors are determined by the proportion of the corresponding load in the total load, as follows: ; ; ; The central control unit will , and This serves as a unified control basis for subsequent shunting ratio generation, operating mode switching, and tidal bidirectional pulse parameter allocation.
[0043] Furthermore, in step S3, the diversion ratios are the particulate matter-dominated path diversion ratio, the volatile organic compound-dominated path diversion ratio, and the thermo-humidity regulation-dominated path diversion ratio, and the sum of the particulate matter-dominated path diversion ratio, the volatile organic compound-dominated path diversion ratio, and the thermo-humidity regulation-dominated path diversion ratio is 1.
[0044] Specifically, the central control unit is based on the dominant factors of particulate pollution. Volatile organic compounds are the dominant factor. and thermo-humidity dominant factors Particulate matter dominant pathway diversion ratio 2. Proportion of volatile organic compounds diverted along the dominant pathway and the proportion of diversion along the dominant path of heat and humidity regulation Among them, the flow distribution ratios of particulate matter-dominant pathway, volatile organic compounds-dominant pathway, and thermo-humidity regulation-dominant pathway correspond to the target flow distribution relationships of the three treatment pathways, and satisfy the constraint that the total distribution amount is consistent with the total intake amount of the system.
[0045] In this embodiment, the central control unit first generates unnormalized allocation values for three processing paths based on three dominant factors and the state parameters of the corresponding paths, and then obtains the traffic splitting ratio through normalization processing. The traffic splitting ratio is constructed in the following way: ; ; ; ; ; ; Among them, a1 to a 10 The central control unit issues target flow rates for each processing path to the flow diversion execution unit based on the generated diversion ratio. The target flow rate is generated by multiplying the total intake volume flow rate by the corresponding diversion ratio. The flow diversion execution unit adjusts the opening of the diversion components for each path according to the target flow rate. The rate of change of the diversion ratio, the flow stabilization process of each processing path, and the execution constraints during the diversion switching process are all handled by the central control unit according to preset control rules.
[0046] Furthermore, the intake phase in step S5 is used to deliver air into the processing path. The stall diffusion phase is used to pause mainstream propulsion to allow pollutants to diffuse into porous and biologically active regions. The reverse release phase is used to make air flow in the opposite direction to the inhalation phase to expel accumulated moisture and residual pollutants.
[0047] Specifically, the central control unit controls the air supply and exhaust actuators to sequentially guide air through the intake phase, stagnant diffusion phase, and reverse release phase in each processing path. In this embodiment, [the following is used as an example]. Indicates the duration of the inhalation phase, in Indicates the duration of the stagnant diffusion phase, in Indicates the duration of the reverse release phase, in This indicates the duration of a single running cycle. A single running cycle consists of the three stages mentioned above in sequence, and their relationship is as follows: ; During the intake phase, the central control unit controls the exhaust and feed units to establish forward flow in each processing path, ensuring that the air to be treated enters the processing unit at the corresponding target flow rate. During the stagnation and diffusion phase, the central control unit stops both forward and reverse drive, bringing the processing unit to a state where mainstream propulsion has ceased. During the reverse release phase, the central control unit controls the exhaust and feed units to establish flow in the opposite direction to that of the intake phase, in order to remove accumulated moisture and residual contaminants from within the processing unit.
[0048] For the particulate matter-dominated pathway, the volatile organic compound (VOC)-dominated pathway, and the thermo-humidity regulation-dominated pathway, the central control unit sets the duration of the inhalation phase, the stagnant diffusion phase, and the reverse release phase for each pathway. The duration of each phase is determined by the corresponding dominant factor and the current operating mode. When particulate matter pollution load is dominant, the central control unit increases the proportion of the inhalation phase in the corresponding cycle of the particulate matter-dominated pathway; when VOC pollution load is dominant, the central control unit increases the proportion of the stagnant diffusion phase in the corresponding cycle of the VOC-dominated pathway; when thermo-humidity regulation load is dominant, the central control unit adjusts the duration allocation of the inhalation and reverse release phases of the thermo-humidity regulation-dominated pathway based on leaf surface moisture and the volumetric moisture content of the composite substrate. The phase switching sequence for each pathway remains the same: inhalation phase, stagnant diffusion phase, and reverse release phase.
[0049] Furthermore, the central control unit switches the system operating mode based on the dominance of particulate pollution load, volatile organic compound pollution load, and thermal and humidity regulation load. The operating modes include particle priority mode, volatile organic compound mineralization priority mode, heat and humidity regulation priority mode, self-regeneration and recovery mode, and conservation and maintenance mode; In the particulate-first mode, the proportion of particulate matter diversion along the dominant path is increased and the duration of the stagnant diffusion phase is shortened. Under the volatile organic compound (VOC) mineralization priority mode, increase the proportion of VOC-dominant pathway diversion and prolong the duration of the stagnation-diffusion phase; In the heat and humidity regulation priority mode, the proportion of diversion in the dominant heat and humidity regulation pathway is increased and the continuous over-humidity of the leaf surface is limited.
[0050] Specifically, the central control unit is based on the dominant factors of particulate pollution. Volatile organic compounds are the dominant factor. Thermo-humidity dominant factors Pressure difference Volumetric moisture content of composite matrix Leaf surface moisture and volatile organic compound reserves The operating mode can be switched. The operating modes include particle priority mode, volatile organic compound mineralization priority mode, thermal and humidity regulation priority mode, self-regeneration and recovery mode, and conservation and maintenance mode.
[0051] In particulate-priority mode, the central control unit increases the proportion of particulate matter-dominant pathway diversion, decreases the proportion of volatile organic compound (VOC)-dominant pathway diversion and thermo-humidity regulation-dominant pathway diversion, and simultaneously adjusts the duration of the particulate matter-dominant pathway phase to maintain a large proportion of the inhalation phase. This mode correction is achieved by superimposing a mode correction amount based on the dominant particulate pollution factor onto the original diversion proportions, followed by normalization.
[0052] Under the volatile organic compound (VOC) mineralization-preferred mode, the central control unit increases the proportion of VOC-dominant pathway diversion, decreases the proportion of particulate matter-dominant pathway diversion and thermo-humidity regulation-dominant pathway diversion, and prolongs the duration of the stagnation-diffusion phase in the VOC-dominant pathway. This mode correction is achieved by superimposing a mode correction amount based on the VOC-dominant factor onto the original diversion proportions, followed by normalization.
[0053] In the heat and humidity priority mode, the central control unit increases the proportion of diversion along the dominant heat and humidity path, decreases the proportion of diversion along the dominant particulate matter path and the dominant volatile organic compound path, and adjusts the diversion based on leaf surface humidity ω. l (t) and the volumetric water content θ of the composite matrix s (t) Constrain the duration of the inhalation phase and the reverse release phase of the dominant thermo-humidity regulation pathway. When the leaf surface humidity reaches a preset threshold, the central control unit reduces the duration of the inhalation phase of the dominant thermo-humidity regulation pathway and increases the corresponding duration of the reverse release phase.
[0054] In self-regeneration recovery mode, the central control unit outputs a dew point swing self-regeneration command to the regeneration execution unit and simultaneously reduces the target flow of each processing path and adjusts the stage duration of each processing path to ensure that the reverse release stage and the operation process of the regeneration execution unit maintain a time coordination relationship.
[0055] In conservation and maintenance mode, the central control unit maintains each processing path at a preset conservation flow rate and ensures that the inhalation, stagnant diffusion, and reverse release phases of each processing path are within preset maintenance ranges. In this mode, the regeneration execution unit is turned off, the status sensing unit continuously outputs various monitoring parameters, and the central control unit continuously judges the operating status.
[0056] Furthermore, the preset triggering conditions in step S6 include: pressure difference exceeding the allowable range, composite matrix volume moisture content exceeding the allowable range, leaf surface moisture continuously exceeding the threshold, and volatile organic compound storage reaching the set upper limit.
[0057] Specifically, the central control unit determines whether to initiate dew point swing self-regeneration based on preset trigger conditions. These preset trigger conditions include differential pressure exceeding the allowable range, composite substrate volumetric moisture content exceeding the allowable range, leaf surface humidity consistently exceeding a threshold, and volatile organic compound (VOC) storage reaching a set upper limit. The central control unit independently determines each of these conditions and uses the fulfillment of any one condition as the trigger for initiating dew point swing self-regeneration.
[0058] In this embodiment, the central control unit uniformly records the trigger result as When any of the following parameters—pressure difference, composite matrix volumetric moisture content, leaf surface humidity, or volatile organic compound storage—meets the preset trigger condition, then... When none of the above parameters meet the preset trigger conditions, let The central control unit is based on Perform a switch to the operating mode. When At this time, the central control unit switches to self-regeneration recovery mode and controls the regeneration execution unit to start the dew point oscillation self-regeneration process.
[0059] During the dew point oscillation self-regeneration process, the regeneration execution unit controls the temperature of the condensation surface in the regeneration flow path. The dew point temperature of the air below the regeneration flow path This causes some of the water vapor in the air to condense. The condensate enters the condensate treatment branch of the regeneration unit. The central control unit continuously collects the pressure difference throughout the entire dew point swing self-regeneration process. Composite matrix volumetric moisture content Leaf surface moisture and volatile organic compound reserves The collected results will be used as the input for exit condition determination.
[0060] Furthermore, the exit conditions in step S7 include: the pressure difference returning to the allowable range, the volumetric moisture content of the composite matrix returning to the allowable range, and the leaf surface moisture returning to the allowable range.
[0061] Specifically, the central control unit decides whether to terminate the dew point oscillation self-regeneration and resume normal operation based on the exit conditions. Exit conditions include the pressure differential returning to the allowable range, the composite substrate volumetric moisture content returning to the allowable range, and the leaf surface moisture content returning to the allowable range. To ensure consistent parameter definitions, this embodiment uses... Indicates the differential pressure recovery threshold, in Indicates the volumetric moisture content recovery threshold of the composite matrix, in order to This indicates the threshold for leaf surface moisture recovery.
[0062] The central control unit determines the three recovery conditions separately and records the three determination results as follows: and .in, This indicates the determination result of the differential pressure recovery condition. This indicates the determination result of the conditions for restoring the volumetric moisture content of the composite matrix. This indicates the determination result of the leaf surface moisture recovery conditions. The three recovery conditions use a unified combination exit relationship: ; when At this time, the central control unit ends the dew point swing self-regeneration, shuts down the regeneration execution unit, and adjusts the current dominant particulate pollution factor. Volatile organic compounds are the dominant factor. and thermo-humidity dominant factors Redetermine the system operating mode.
[0063] After the dew point swing self-regeneration ends, the central control unit does not directly switch the shunting ratio and stage duration to the target values of the new mode. Instead, it restores the values to the target values corresponding to the new mode cycle by cycle according to the preset recovery rules. The recovery rules are executed by the central control unit according to the preset recovery step size to maintain the continuous operation of the shunting execution unit and the supply and exhaust execution unit during the mode recovery process.
[0064] Furthermore, the central control unit adaptively adjusts the diversion ratio, inhalation phase duration, stagnation-diffusion phase duration, and reverse release phase duration based on historical operating data.
[0065] Specifically, the central control unit adaptively adjusts the diversion ratio, inhalation phase duration, stagnation-diffusion phase duration, and reverse release phase duration based on historical operating data. To ensure consistent parameter definitions, in this embodiment, the historical operating data set is denoted as... Historical operational data set Includes particulate matter concentrations from at least multiple historical control periods. Volatile organic compound concentration Intake temperature Intake relative humidity pressure difference Composite matrix volumetric moisture content Leaf surface moisture Volatile organic compound reserves Diversion ratio and duration of each path stage.
[0066] The central control unit is based on historical operating data sets. The diversion ratio correction and the stage duration correction are calculated and then added to the diversion ratio and stage duration of the current control cycle. In this embodiment, the diversion ratio correction is generated using a combination of historical load deviation and historical state deviation. ; ; ; in, This is the historical particulate pollution load deviation item. Historical Volatile Organic Compound (VOC) Pollution Load Deviation Item This is the historical thermal and humidity regulation load deviation term. This is the historical pressure difference deviation term. This is the historical composite matrix volume moisture content deviation term. This refers to the historical leaf surface moisture deviation item. to To adaptively adjust the weighting coefficients.
[0067] The central control unit updates the diversion ratios for the particulate matter-dominant path, the volatile organic compound-dominant path, and the thermo-humidity regulation-dominant path based on the diversion ratio correction, and then performs normalization processing on the updated diversion ratios again. For the duration of the inhalation phase, the duration of the stagnant diffusion phase, and the duration of the reverse release phase, the central control unit generates corresponding correction values based on the historical operating data set H(t) using the same correction method, and updates the phase duration parameters for each processing path. The updated phase durations maintain the unchanged periodic structure of each path; that is, the periodic duration of each path is composed of the inhalation phase duration, the stagnant diffusion phase duration, and the reverse release phase duration in sequence.
[0068] The central control unit sends the adaptively adjusted flow split ratio to the flow split execution unit and the adaptively adjusted stage duration to the supply and exhaust execution unit. The flow split execution unit executes the flow allocation for the next control cycle based on the adaptively adjusted flow split ratio, and the supply and exhaust execution unit executes the stage switching for the next control cycle based on the adaptively adjusted stage duration. In subsequent control cycles, the central control unit continues to collect new operating data and write it into the historical operating data set H(t), thus forming a continuously updated adaptive adjustment process.
[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
