Description

Technical Field

[0001] This invention relates to pressurization facilities, specifically to a pressurized residential facility and its control system and method. Background Technology

[0002] The low air pressure in high-altitude areas can negatively impact the health of people living there, causing discomfort and affecting their work and daily life. This impact is even greater for those who need to stay at high altitudes for short periods; even a mild cold at high altitudes can rapidly worsen and become life-threatening if not treated promptly and effectively. To mitigate the adverse effects of low air pressure, pressurized buildings (fixed) or pressurized living facilities (integrated, mobile facilities) can be installed to provide the same external pressure in high-altitude areas as in plains areas, thereby alleviating altitude sickness.

[0003] Currently, most pressurized living facilities on the market use oxygen chambers, which are small and make people feel depressed. They also have low light transmittance, which can easily cause a sense of claustrophobia. In addition, their pressurization equipment works under high load for a long time and has poor heat dissipation, which often leads to malfunctions.

[0004] Furthermore, current pressurized living facilities have the following drawbacks: 1. Structural disadvantages: The oxygen supply and pressurization pipelines in micro-pressurized spaces are generally centrally located, making it impossible to separately regulate oxygen supply and pressurization; 2. Disadvantages in control methods: Existing control methods generally rely on simple threshold judgments and do not employ more intelligent control approaches. Current control methods typically use oxygen or carbon dioxide concentration as the control target, controlling the concentration of a single gas, which cannot meet users' higher requirements for a suitable living environment. Summary of the Invention

[0005] The purpose of this invention is to provide a pressurized living facility and its control system and method. This facility avoids spatial oppression, allows for large-area lighting, and prevents malfunctions of the pressurization equipment and pressurization cabinet control equipment due to high temperatures. The control system can control the oxygen supply system and the pressurization system separately. This control method introduces composite air performance indicators, which can effectively improve the user experience.

[0006] The technical solution adopted in this invention is: This invention provides a pressurized living facility, comprising a prefabricated living room and a mobile pressurization cabinet. The living room includes a grid-like frame assembled from rods and nodes, a top plate installed on the top grid of the frame, a bottom plate installed on the bottom grid of the frame, and wall panels, glass panels, and a door frame installed on the side grids of the frame. The installation edges of the top plate, bottom plate, wall panels, glass panels, and door frame are all sealed with sealing strips. The sealing strips are pre-tightened on the frame by sealing pressure plates. A pressure-bearing airtight door is installed on the door frame. When the pressure-bearing airtight door is closed, the entire living room is a sealed space. The pressurization cabinet includes a sealed mobile cabinet. The interior of the mobile cabinet is divided into three layers by a partition with ventilation holes. The bottom layer houses the cold end of the refrigeration equipment, the middle layer houses the pressurization cabinet control equipment, and the top layer houses the pressurization equipment. The bottom layer is equipped with an air intake fan and a condensate drain structure, and the top layer is equipped with an exhaust fan.

The booster cabinet control device controls the number of intake fans and exhaust fans to be turned on according to the outdoor temperature. Under the action of the intake fans and exhaust fans, an upward airflow is formed in the mobile cabinet to dissipate heat and cool down the booster cabinet control device and the booster equipment. When the outdoor temperature exceeds the set value, the booster cabinet control device controls the refrigeration device to be turned on. The refrigeration device performs forced cooling on the booster cabinet control device and the booster equipment in the mobile cabinet. The condensate generated by the refrigeration is discharged from the mobile cabinet through the condensate discharge structure.

[0011] Preferably, the air intake fan is equipped with a filter element for filtering the incoming air, and the filter element can be pulled out and installed on the mobile cabinet.

[0019] Furthermore, the compressed end of the high-pressure sealing strip is arc-shaped.

[0020] Furthermore, the limiting strip is made of metal with a rectangular cross-section.

The transmission mechanism includes an elastic rod located on the side of the movable sealing frame to contact the closed door panel, and a rotating rod located outside the movable sealing frame. A pressing mechanism and a rotating cylinder are fixed on the rotating rod, and an arc-shaped groove is provided on the rotating cylinder. The elastic rod extends into a sliding rod, and the end of the sliding rod is inserted into the arc-shaped groove. The sliding mechanism slides in the groove to drive the rotating rod to rotate. After the clamping mechanism follows the rotation of the rotating rod, it contacts the movable sealing frame to drive it to move closer to or away from the door panel, thereby driving the sealing element to press or move away from the door panel. The door panel is adapted to the door frame. A sealing groove adapted to its sealing element is opened on the end face of the door panel near the movable sealing frame. A circular groove is opened on the side of the door panel for the drive rod of the drive device to be inserted. A guide groove adapted to the guide plate on the door frame is opened on the bottom end face of the door panel. The drive device connects the door frame and the door panel.

[0026] Furthermore, a guide plate is fixed on the bottom surface of the door frame, and the guide plate is inserted into the guide groove of the door panel.

[0027] Furthermore, rubber rings are installed on the edge of the door frame.

[0028] The present invention also provides a control system for a pressurized living facility, applicable to the aforementioned pressurized living facility, comprising: the aforementioned living room; a sensor system installed in the living room for monitoring and collecting various sensor data within the living room; an oxygen supply system connected to the living room for supplying oxygen to the living room; a pressurization system employing cedar pressurization equipment and connected to the living room for regulating the air pressure within the living room; and a controller installed in the living room and connected to the sensor system, oxygen supply system, and pressurization system for establishing a control model and, based on the collected sensor data, controlling the stability of the gas concentration inside the living room by adjusting the airflow distribution between the pressurization system and the oxygen supply system.

[0029] Preferably, the sensor system includes: a temperature sensor, a humidity sensor, a pressure sensor, an oxygen concentration sensor, and a carbon dioxide concentration sensor.

[0030] Preferably, the oxygen supply system includes: a piston air compressor, an intake solenoid valve assembly, a molecular sieve system, a one-way valve assembly, a connecting pipe, and an oxygen supply pipe; wherein: one end of the molecular sieve system is connected to the living room through the oxygen supply pipe, the piston air compressor is connected to the connecting pipe through the intake solenoid valve assembly, and the connecting pipe is connected to the other end of the molecular sieve system; the one-way valve assembly is installed in the connecting pipe.

[0031] Furthermore, the pressurization system includes: a vortex fan, an aluminum finned fan, and pressurization pipes; wherein: the vortex fan, the aluminum finned fan, the pressurization pipes, and the living room are connected in sequence, and the connecting pipes are connected to the pressurization pipes.

[0032] Preferably, the living room is also equipped with a manual / automatic safety valve. When the pressure exceeds a certain threshold, the controller controls the manual / automatic safety valve to open and release the pressure.

[0033] Preferably, the controller's control model uses a composite air performance index for control. The composite air performance index is determined based on the equivalent proportion concentration of each sub-air index, including oxygen, carbon dioxide, temperature, and humidity, in a normal habitable environment, combined with the weighting factors of user habits or active control strategies.

[0034] Preferably, both the pressurization system and the oxygen supply system employ air purification devices at their air intake ends.

[0035] This invention also provides a control method for a pressurized residential facility, employing the aforementioned control system for the pressurized residential facility, comprising the following steps: The system performs a self-check to determine if it is in emergency mode; if so, it performs emergency depressurization; if not, it selects a mode; if it is in oxygen production mode, it controls the oxygen concentration, and the controller controls the system to operate smoothly; if it is in manual mode, it manually controls the system to depressurize or increase pressure, and during the pressure increase process, the controller controls the system to operate smoothly; if it is in automatic mode, it automatically determines the following situations: if a fire alarm signal is received or an emergency power outage occurs, it performs emergency depressurization; if the pressure is lower than a set threshold, or the carbon dioxide concentration exceeds a set threshold, or a set time interval is reached, it performs ventilation and pressure increase, and during the pressure increase process, the controller controls the system to operate smoothly; if the set pressure value is not reached, it increases pressure, and during the pressure increase process, the controller controls the system to operate smoothly; when the system is operating smoothly, the controller uses composite air performance indicators as the control object for real-time control.

[0036] Furthermore, the specific steps of the controller in this method to perform real-time control with composite air performance indicators as the controlled object include: establishing composite air performance indicators based on the equivalent proportion concentration of each sub-indicator of air, including oxygen, carbon dioxide, temperature, and humidity, in a normal habitable environment, combined with the weighting factors of user habits or active control strategies; performing differential transition on the composite air performance indicators; using an extended state observer to observe the extended state process; and applying nonlinear error feedback control to form a closed-loop control of the composite air performance indicators.

[0037] Furthermore, the formula for the composite air performance index is:

[0038] in, The equivalent proportion of each sub-item of air quality index in a normal and suitable living environment includes oxygen, carbon dioxide, ambient temperature, and humidity, where n is the number of sub-items of air quality index. These are weighting factors based on user habits or proactive control strategies.

[0039] Furthermore, the specific methods for establishing closed-loop control of composite air performance indicators include: Differential transition of the target air performance index:

[0040] Wherein, the second-order steepest function is , and These are system control parameters; An extended state observer is used, and the extended state observation process is as follows:

[0041] The application of nonlinear error feedback control specifically involves:

[0042] in, Output the actual state of the system; These are the observed air performance indicators; The differential signal of the observed performance index; The total system disturbance observed; , which is the observation bias, representing the difference between the system's observed output and the actual output; The sampling period during the system discretization process; These are system control parameters, related to the observer's bandwidth, and determined by the step size used. For system control parameters, 5 ≤ ≤10 ; It is a nonlinear observation function.

[0043] The beneficial effects of this invention are as follows: The living room uses a grid-like frame and various panels, allowing for customized size and layout. The spacious design allows users to place beds, furniture, and other items as needed, avoiding a cramped feeling. Since the glass panels are installed on the grid sides of the frame, they only bear air pressure, not structural stress, enabling large-area lighting and preventing a claustrophobic feeling. The pressure cabinet protects the pressure boosting equipment and its control system, while also providing heat dissipation and cooling, preventing malfunctions due to overheating.

[0044] The control system of this invention adopts a composite pipeline design, which is divided into an oxygen supply system and a pressurization system. It can be controlled separately or in combination with composite air performance indicators. The control accuracy is high and the adjustment method is more flexible and intelligent.

[0045] In the control method of this invention, a composite air performance index is introduced, fully considering the equivalent proportion concentration of each sub-indicator in a normal and suitable living environment, as well as the weighting factors extracted based on user habits or active control strategies. This innovative approach uses a "composite air performance index" as the control indicator, which, compared to using a single gas concentration, effectively improves the user experience. Furthermore, it fully utilizes the coupled control of oxygen and carbon dioxide concentrations, controlling the rational distribution of fresh air volume through the combined effect of these two indicators. Nonlinear error feedback control is employed, a nonlinear implementation based on the classic PID control law of traditional linear control systems. The processing of error signals and error derivative signals is significantly improved, resulting in higher accuracy of closed-loop control. By adjusting the internal environmental pressure, a better sleep environment is provided for people living in high-altitude areas at night. Increasing atmospheric pressure simulates the environment of low-altitude areas, achieving better sleep and rest conditions. The safety protection of internal gas pressure and the monitoring and control of key gas concentrations such as oxygen and carbon dioxide are feasible, safe, and reliable, with reasonable redundancy configuration fully considered.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0068] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0069] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0070] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection.

[0071] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0072] Example 1 This embodiment discloses a pressurized residential facility, such as Figures 1 to 7 As shown, it consists of two parts: a prefabricated living room and a mobile pressurization cabinet.

[0073] like Figure 1 As shown, the living room includes a grid-like frame assembled from rods 1 and nodes 2, a top plate 3 installed on the top grid of the frame, a bottom plate 5 installed on the bottom grid of the frame, and wall panels 4, glass panels 8, and door frames 7 installed on the side grids of the frame, as shown. Figure 2 As shown, the installation edges of the top plate 3, bottom plate 5, wall plate 4, glass plate 8 and door frame 7 are all sealed by sealing strips 10. The sealing strips 10 are pre-tightened on the frame by sealing pressure plate 9. A pressure-bearing airtight door 6 is installed on the door frame 7. When the pressure-bearing airtight door 6 is closed, the entire living room is a sealed space.

[0074] like Figure 3 As shown, in this embodiment, rod 1 includes a rod-shaped square tube 1-1 and threaded hole plates 1-2 at both ends of the rod-shaped square tube 1-1. Node 2 includes a node component 2-1 composed of square tubes, hole plates 2-3 at each mating end of the node component 2-1, bolts 2-2 passing through the hole plates 2-3, and nuts 2-4 fitted onto the bolts 2-2. Nuts 2-4 are located outside the hole plates 2-3, and the enlarged head of the bolts 2-2 is located inside the hole plates 2-3, with the threaded head extending into the threaded hole plates 1-2. Tightening the nuts 2-4 achieves a tight connection between rod 1 and node 2. With this configuration, only tightening the nuts 2-4 is needed to tightly connect rod 1 and node 2, making operation convenient and facilitating the installation and maintenance of the living room.

[0075] like Figure 3 As shown, in this embodiment, the nut 2-4 has an opening 2-5 on its side. The nut 2-4 and the bolt 2-2 are circumferentially limited by a fixing pin 2-6 passing through the opening 2-5. This setting can prevent the nut 2-4 from loosening and ensure that the connection is absolutely reliable.

[0076] In this embodiment, the top plate 3, the bottom plate 5, and the wall plate 4 are made of steel plate or fiberglass plate.

[0077] like Figures 4 to 6As shown, in this embodiment: the sealed pressure-bearing door is a swing type, including a door panel 6-2. One side of the door panel 6-2 is installed by a hinge 6-1, and the other side is provided with a door lock assembly 6-3 that can restrict the inward opening of the door panel 6-2. The door panel 6-2 is provided with a low-pressure sealing strip 6-4, a limiting strip 6-5, and a high-pressure sealing strip 6-6 on the sealing pressure-bearing surface that cooperates with the door frame 7. The low-pressure sealing strip 6-4 is arranged in a ring around the door panel 6-2 and adopts a hollow flexible structure. One end of it is fixed to the door panel 6-2, and the other end is provided with a magnet that can be attracted to the door frame 7. The high-pressure sealing strip 6-6 is arranged in a ring around the door panel 6-2 and is located inside the ring of the low-pressure sealing strip 6-4. It adopts a hollow rigid structure. One end of it is fixed to the door panel 6-2, and the other end is higher than the limiting strip 6-5. The limiting strip 6-5 is located between the low-pressure sealing strip 6-4 and the high-pressure sealing strip 6-6 to prevent the high-pressure sealing strip 6-6 from being excessively compressed. In the absence of pressure difference between indoors and outdoors, the low-pressure sealing strip 6-4 can achieve a seal by magnetically attaching to the door frame 7, relying solely on the restriction of the door lock assembly 6-3, even without additional external pressure. The required locking force is low (lower than the locking force standard of ordinary subway car doors and airplane cabin doors). Furthermore, it is installed using hinges 6-1, allowing for a larger door panel 6-2. When air is injected into the room, the injected gas cannot leak to the outside due to the obstruction of the low-pressure sealing strip 6-4, causing the indoor air pressure to rise. This air pressure pushes the door panel 6-2 outward, compressing the high-pressure sealing strip 6-6. The air in the hollow structure of the high-pressure sealing strip 6-6 increases the elasticity of the sealing ring, achieving a reliable seal even with a small pressure difference between indoors and outdoors. Moreover, due to the presence of the limiting strip 6-5, the high-pressure sealing strip 6-6 will not be over-compressed, ensuring its service life and avoiding the need for a large locking force. Therefore, this sealed pressure-bearing door can maintain good airtightness under both low and high pressure conditions, requiring less pre-tightening force and allowing for a larger door panel 6-2.

[0078] like Figure 5 As shown, in this embodiment, two door frames 7 are used: an outer door frame 7-1 installed on the side grid of the frame, and an inner door frame 7-2 installed inside the outer door frame 7-1. The door panel 6-2 is installed on the outer door frame 7-1 via hinges 6-1. A door lock assembly 6-3 is used to lock and limit the door panel on the outer door frame 7-1. The door panel 6-2 cooperates with the inner door frame 7-2 via a low-pressure sealing strip 6-4, a limiting strip 6-5, and a high-pressure sealing strip 6-6. The outer door frame 7-1 compensates for manufacturing errors in the frame and provides standard installation space for the sealed pressure-bearing door. The inner door frame 7-2 provides the pressure-bearing surface and sealing surface for the sealed pressure-bearing door. The design of two door frames 7 improves installation accuracy, and the line of action between the pressure generated by the pressure difference and the resistance preventing further door rotation is very short, reducing the strength requirements for the door panel 6-2.

[0079] like Figure 4 and Figure 5 As shown, in this embodiment, hinge 6-1 uses a double hinge: the hinge closer to the door frame 7 is the main rotating hinge, and the hinge closer to the door panel 6-2 is the limiting rotating hinge. The main rotating hinge ensures that the door panel 6-2 can rotate freely. The limiting rotating hinge, in conjunction with the main rotating hinge, ensures that the door panel 6-2 vertically compresses the sealing strip 10 during closing, and that the rotation of the door is relatively controllable during opening. The tangential movement between the door panel 6-2 and the sealing strip 10 is very small, greatly reducing damage to the sealing strip 10 during closing and improving the lifespan of the sealing strip 10.

[0080] like Figure 5 As shown, in this embodiment, the door lock assembly 6-3 includes an inner handle and an outer handle that are linked together, as well as a locking block on the inner handle and a stop block on the door frame 7. When the inner handle is rotated to a certain range, the locking block locks onto the stop block to restrict the door panel 6-2 from opening inward.

[0081] like Figure 6 As shown in this embodiment, the compression end of the high-pressure sealing strip 6-6 is arc-shaped, which can ensure a good sealing effect when compressed at any angle.

[0082] In this embodiment, the limiting strip 6-5 is preferably a metal strip with a rectangular cross-section to ensure the limiting effect.

[0083] like Figure 7 As shown, the booster cabinet includes a sealed mobile cabinet 12. The interior of the mobile cabinet 12 is divided into three layers by a partition 13 with ventilation holes 15. The bottom layer houses the cold end of the refrigeration equipment, the middle layer houses the booster cabinet control equipment (not shown in the figure), and the top layer houses the booster equipment (not shown in the figure). The bottom layer is equipped with an intake fan 16 and a condensate drain structure, and the top layer is equipped with an exhaust fan 11. The exterior of the mobile cabinet 12 is equipped with a temperature sensor 14 and the hot end of the refrigeration equipment. The booster equipment is connected to the living room through an air circuit system.

[0084] The working method of the booster cabinet is as follows: In the working state, the temperature sensor 14 uploads the outdoor temperature to the booster cabinet control device. The booster cabinet control device controls the number of air intake fans 16 and exhaust fans 11 to be turned on according to the outdoor temperature. Under the action of the air intake fans 16 and exhaust fans 11, an upward airflow is formed in the mobile cabinet 12 to dissipate heat and cool down the booster cabinet control device and the booster equipment. When the outdoor temperature exceeds the set value, the booster cabinet control device controls the cooling device to be turned on. The cooling device forces the booster cabinet control device and the booster equipment in the mobile cabinet 12 to cool down. The condensate generated by the cooling is discharged from the mobile cabinet 12 through the condensate discharge structure. This setting can effectively dissipate heat and save energy.

[0085] like Figure 7As shown, in this embodiment, the air intake fan 16 is equipped with a filter element 17 for filtering the incoming air. The filter element 17 is removably mounted on the movable cabinet 12. The filter element 17 can prevent dust and other impurities brought in by the incoming air from entering the cabinet, and its removable mounting method makes it easy to replace.

[0086] like Figure 7 As shown, in this embodiment, the refrigeration equipment includes a compressor 22, a refrigeration coil 21, and a condenser coil 23. The compressor 22 and the refrigeration coil 21 are located inside the mobile cabinet 12, and the condenser coil 23 is located outside the mobile cabinet 12.

[0087] like Figure 7 As shown, in this embodiment, the condensate drainage structure includes a water receiving tray 19 and a drain outlet 20. The condensate collected by the water receiving tray 19 is discharged from the mobile cabinet 12 through the drain outlet 20.

[0088] like Figure 7 As shown, in this embodiment, the bottom of the mobile cabinet 12 is equipped with casters 18 with brakes.

[0089] The pressurized living facility provided in this application features a living room with a grid-like frame and various panels, allowing for customized space size and configuration. The spacious layout allows users to place beds, furniture, and other items as needed, avoiding a cramped feeling. Since the glass panels 8 are installed on the grid side of the frame, they only bear air pressure, not structural pressure, enabling large-area lighting and preventing a claustrophobic feeling. The frame and various panels of the living room are assembled, making assembly and disassembly simple and maintenance convenient. The sealing plate 9 provides pre-tightening force to the sealing strip 10, ensuring its airtightness under low pressure. The pressurization cabinet protects the pressurization equipment and its control equipment, while also providing heat dissipation and cooling, preventing malfunctions due to high temperatures. The ventilation holes 15 of the partition 13, in addition to ventilation, also serve to reduce noise.

[0090] Example 2 like Figures 8 to 17As shown, for pressurized residential facilities, this embodiment provides another form of sealed pressure-bearing door. Specifically, the sealed pressure-bearing door is a sliding type, including a sealing device, a door panel 2a, and a drive device 3a. The sealing device includes a movable sealing frame 7a, a pressing mechanism, a sealing element 8a, and a transmission mechanism. The sealing element 8a (which may be a sealing ring) is fixed to the side of the movable sealing frame 7a near the door panel 2a. The transmission mechanism is connected to the movable sealing frame 7a to adjust the distance between it and the door panel 2a. The transmission mechanism includes an elastic rod located on the side of the movable sealing frame 7a to contact the closed door panel 2a, and a rotating rod 13a located outside the movable sealing frame 7a (the rotating rod 13a is supported on the door frame 1a by a bearing, thereby realizing rotation relative to the door frame 1a). A pressing mechanism and a rotating cylinder 15a are fixed on the rotating rod 13a. An arc-shaped groove 1501a is opened on the rotating cylinder 15a, and the elastic rod extends... A sliding rod 1701a is provided. The end of the sliding rod 1701a is inserted into the arc-shaped sliding groove 1501a and slides to drive the rotating rod 13a to rotate. After the pressing mechanism rotates with the rotating rod 13a, it contacts the movable sealing frame 7a to drive it to move closer to or away from the door panel 2a, thereby driving the sealing element 8a to press or move away from the door panel 2a. The door panel 2a is adapted to the door frame 1a. A sealing groove 202a adapted to the sealing element 8a is provided on the end face of the door panel 2a near the movable sealing frame 7a. A circular groove 201a is provided on the side of the door panel 2a for the driving rod of the driving device 3a to be inserted. A guide groove 203a adapted to the guide plate 9a on the door frame 1a is provided on the bottom end face of the door panel 2a. The driving device 3a connects the door frame 1a and the door panel 2a. The base of the driving device 3a is fixed on the door frame 1a. The driving rod of the driving device 3a extends into the circular groove 201a of the door panel 2a and connects to it.

[0091] The pressing mechanism is a cam 14a fixed to the outside of the rotating rod 13a (in this embodiment, at least two cams 14a are provided on each rotating rod 13a, so as to stably push the movable sealing frame 7a to make fine adjustments to the distance. When the door panel 2a is closed, the cam 14a rotates, and the movable sealing frame 7a can press the door panel 2a tightly in all directions, thereby pressing the sealing element 8a, thus improving the overall sealing effect). The inner and outer end faces of the door panel 2a are respectively provided with movable sealing frames 7a (this seals the inner and outer sides of the door body, thereby improving the sealing performance of this sealing device); the elastic rod includes a push rod 17a and a sleeve fitted on the end of the push rod 17a and The fixed cylinder 16a is elastically connected to the push rod 17a (the push rod 17a and the fixed cylinder 16a can be elastically connected by springs, pneumatic damping, etc., so that when the sliding door panel 2a is opened, the cam 14a can be driven to rotate by the rebound force, releasing the movable sealing frame 7a and the sealing element 8a, so that the door panel 2a can slide freely). The fixed cylinder 16a is fixed on the door frame 1a, and the push rod 17a is fixedly connected to the sliding rod 1701a. The movable sealing frames 7a located at both ends of the door panel 2a are respectively provided with elastic rods and rotating rods 13a. The elastic rod also includes a connecting plate 18a that connects the push rod 17a of the two movable sealing frames 7a.

[0092] In this embodiment, the sealing device further includes a connecting strip 6a located between the door frame 1a and the movable sealing frame 7a to seal the gap between them. The connecting strip 6a may be made of a flexible material. One end of the connecting strip 6a is connected to a rubber ring 10a on the door frame 1a, and the other end is fixedly connected to the movable sealing frame 7a to ensure sealing performance. Because the connecting strip 6a is flexible, it is deformable, which ensures a stable connection between the movable sealing frame 7a and the connecting strip 6a during movement.

[0093] In this embodiment, a positioning rod 11a is fixed to the side of the movable sealing frame 7a near the door frame 1a, and a positioning cylinder 12a is fixed to the door frame 1a. The positioning cylinder 12a is sleeved on the outside of the positioning rod 11a, and the positioning rod 11a is movable relative to the positioning cylinder 12a. The positioning rod 11a and the positioning cylinder 12a constitute a positioning mechanism. Each movable sealing frame 7a is provided with at least three positioning mechanisms. By setting the positioning mechanism, the movable sealing frame 7a and the door frame 1a are connected, and the distance between the two can be adjusted by sliding the positioning rod 11a.

[0094] In this embodiment, a guide rod 4a is fixed on the door frame 1a, and a sliding sleeve 5a for the guide rod 4a to pass through is fixed on the top of the door panel 2a. A guide plate 9a is fixed on the bottom surface of the door frame 1a, and the guide plate 9a is inserted into the guide groove 203a of the door panel 2a. The sliding sleeve 5a and the guide groove 203a cooperate with the guide rod 4a and the guide plate 9a of the door frame 1a to limit and guide the top and bottom of the door panel 2a respectively, so as to facilitate the sliding of the door panel 2a and improve the stability of the door panel 2a during the sliding process.

[0095] In this embodiment, a rubber ring 10a is installed on the edge of the door frame 1a. The edge of the door frame 1a refers to the quadrilateral edge that is opened inside it, and the rubber ring 10a has a square structure.

[0096] In this embodiment, the drive device 3a can be a small servo electric cylinder or other drive component, and two such devices can be provided.

[0097] When the drive device 3a closes the door panel 2a, the right side of the door panel 2a pushes the connecting plate 18a to move to the right, thereby causing the two push rods 17a connected to it to move to the right. Since the push rods 17a are inserted into the fixed cylinder 16a, the springs installed in the fixed cylinder 16a are compressed. At the same time, the sliding rod 1701a at the bottom of the push rod 17a moves to the right. Since the sliding rod 1701a is inserted into the arc-shaped groove 1501a on the rotating cylinder 15a, the rotating cylinder 15a is pushed to rotate. When the rotating cylinder 15a rotates, it drives the rotating rod 13a to rotate, causing the cam 14a on the rotating rod 13a to rotate. The rotation of the cam 14a can push the movable sealing frame 7a to move closer to the door panel 2a. When it moves into place, the movable sealing frame 7a presses the sealing element 8a tightly into the sealing groove 202a on the door panel 2a, so that the door panel 2a and the door frame 11a are sealed.

[0098] This embodiment uses a movable sealing frame 7a and a sealing element 8a in conjunction with a movable door panel 2a. When the door panel 2a is closed, the movable sealing frame 7a moves closer to the door panel 2a to seal it tightly. When the door panel 2a is opened, the movable sealing frame 7a moves outward without interfering with the opening of the door panel 2a, thus achieving a seal on the movable door panel 2a. In addition, the movable sealing frames 7a on both sides exert a clamping pressure on the door body, which can improve the stability of the door panel 2a. This is suitable for situations where the internal and external air pressures of the pressurization facility are different, ensuring that the structure maintains stability and sealing.

[0099] Example 3 like Figure 18As shown, this embodiment provides a control system for a pressurized living facility, applicable to the aforementioned pressurized living facility, comprising: the aforementioned living room; a sensor system 9b, installed in the living room, for monitoring and collecting various sensor data within the living room; an oxygen supply system, connected to the living room, for supplying oxygen to the living room; a pressurization system, employing cedar wood pressurization equipment, connected to the living room, for regulating the air pressure within the living room; and a controller, installed in the living room, connected to the sensor system 9b, the oxygen supply system, and the pressurization system, for establishing a control model, and controlling the stability of the internal gas concentration of the living room by adjusting the airflow distribution between the pressurization system and the oxygen supply system based on the collected sensor data.

[0100] In this embodiment, preferably, the sensor system includes: a temperature sensor, a humidity sensor, a pressure sensor, an oxygen concentration sensor, and a carbon dioxide concentration sensor. Wherein: A carbon dioxide concentration detector is installed. When the carbon dioxide concentration exceeds the standard, the controller opens the exhaust valve and makes the fan work at a high frequency to increase the ventilation volume and ensure that the carbon dioxide concentration is quickly adjusted to a suitable level.

[0101] An oxygen concentration detector is installed to ensure a constant and reliable oxygen concentration inside the micro-pressurized space. When the oxygen concentration is too low, oxygen is added. Once the set oxygen concentration is reached, diffused oxygen supply or nasal oxygen inhalation is provided. At the same time, the stability and reliability of the oxygen concentration inside the micro-pressurized space are strictly monitored. If the oxygen concentration is too high or too low, the system will quickly intervene to adjust the oxygen concentration to a suitable state.

[0102] The system is equipped with a pressure detection device and inlet / outlet solenoid valves. When the pressure reaches the standard, pressurization stops; when the pressure is below the standard, pressurization begins.

[0103] In a preferred embodiment of the present invention, the oxygen delivery system includes: a piston air compressor 1b, an intake solenoid valve assembly 2b, a molecular sieve system 3b, a one-way valve assembly 4b, a connecting pipe, and an oxygen delivery pipe 5b; wherein: One end of the molecular sieve system 3b is connected to the living room via the oxygen supply pipe 5b. The piston air compressor 1b is connected to the connecting pipe via the intake solenoid valve group 2b. The connecting pipe is connected to the other end of the molecular sieve system 3b. The one-way valve group 4b is installed in the connecting pipe.

[0104] In a preferred embodiment of the present invention, the pressurization system includes: a vortex fan 6b, an aluminum fin fan 7b, and a pressurization pipe 8b; wherein: the vortex fan 6b, the aluminum fin fan 7b, the pressurization pipe 8b, and the living room are connected in sequence, and the connecting pipe is connected to the pressurization pipe 8b.

[0105] In a preferred embodiment of the present invention, a manual-automatic integrated safety valve 10b is also provided in the living room. When the pressure exceeds a certain threshold, the controller controls the manual-automatic integrated safety valve 10b to open and release pressure. The manual-automatic integrated safety valve 10b can automatically open and release pressure when the indoor pressure is too high; it can also serve as an active pressure relief device for personnel entry and exit, assisting the exhaust solenoid valve in releasing pressure.

[0106] In a preferred embodiment of the present invention, the controller's control model employs a composite air performance index for control. The composite air performance index is determined based on the equivalent proportion concentration of each sub-air index, including oxygen, carbon dioxide, temperature, and humidity, in a normal habitable environment, combined with the weighting factors of user habits or active control strategies.

[0107] In a preferred embodiment of the present invention, in order to further ensure a good living environment, air purification devices are used at the air intake ends of both the pressurization system and the oxygen supply system.

[0108] This control system employs a composite pipeline design, divided into an oxygen delivery system and a pressurization system. These systems can be controlled separately or in combination with other air performance indicators. The control precision is high, and the adjustment methods are more flexible and intelligent.

[0109] Example 4 like Figure 19 and Figure 20 As shown, this embodiment provides a control method for a pressurized residential facility, employing the aforementioned control system for the pressurized residential facility.

[0110] When setting the control algorithm, considering that the normal concentration of carbon dioxide in the environment is 500 ppm and the oxygen concentration is 20.9%, and that the input source for carbon dioxide regulation is filtered clean fresh air, while the source for oxygen concentration regulation is a composite gas with an oxygen concentration of 90% after passing through an oxygen generator, the algorithm proposes to use "air performance" as the control index. Based on the weighting ratio, a composite "air performance" is derived. "Indicator parameters".

[0111] Specific implementation steps: I. Establish composite air performance indicators Composite air quality indicators were confirmed through user settings or user usage data collection and analysis, and then processed via cloud computing. The weighting ratio is based on the core control indicators of carbon dioxide concentration and oxygen concentration.

[0112]

[0113] in, It refers to the equivalent concentration of each sub-item of air quality in a normal and suitable living environment, including oxygen, carbon dioxide, ambient temperature, humidity, etc. The composite control index is obtained by extracting weighting factors based on user habits or proactive control strategies.

[0114] II. Differential Transition of Target Air Performance Indicators

[0115] A second-order tracking differentiator is used to analyze the target aerodynamic performance signal. The transition process is performed using a second-order steepest function. This avoids the control system from lagging behind due to sudden changes in the target signal. and As a system control parameter, it is related to the system sampling time step and the speed of the filtering process, and is adjusted manually.

[0116] III. Using an extended state observer, the extended state observation process

[0117] By expanding the total disturbance of the system into a new state variable through extended state observation, and then reconstructing the system using the input and output of the system, we can obtain the original state variable of the system and all states of the disturbance.

[0118] in, Output the actual state of the system; These are the observed air performance indicators; The differential signal of the observed performance index; This refers to the total system disturbance observed. This represents the observation bias, which is the difference between the system's observed output and the actual output. The sampling period during the system discretization process; These are system control parameters, generally related to the observer's bandwidth, and determined by the step size used; These are system control parameters, typically 5. ≤ ≤ 10 ; It is a nonlinear observation function; IV. Application of Nonlinear Error Feedback Control

[0119] Nonlinear error feedback control is a nonlinear implementation based on the classical PID control law of traditional drive-by-wire control systems, focusing on the error signal and its derivative. Since a nonlinear control combination is used, and disturbances are observed and compensated in the extended state observation of the ESO (Electronic Stability Oscillator), the integral term can be neglected.

[0120] In summary, a closed-loop control process has been formed, as shown in the appendix. Figure 20 The overall control system ensures a stable and reliable gas concentration inside the miniature pressurized space, suitable for rest, by adjusting the airflow distribution in the pressurization and oxygen supply pipelines.

[0121] This control method introduces a composite air performance index, fully considering the equivalent concentration ratio of each sub-indicator in a normal, suitable living environment, as well as weighting factors derived from user habits or active control strategies. It innovatively proposes using a "composite air performance index" as the control indicator, which, compared to using a single gas concentration, effectively improves the user experience. Furthermore, it fully utilizes the coupled control of oxygen and carbon dioxide concentrations, controlling the rational distribution of fresh air volume through the combined effect of these two indicators. Nonlinear error feedback control is employed, a nonlinear implementation based on the classic PID control law of traditional linear control systems. The processing of error signals and error derivative signals is significantly improved, resulting in higher closed-loop control accuracy. By adjusting the internal environmental pressure, a better sleep environment is provided for people living in high-altitude areas at night. Increasing atmospheric pressure simulates the environment of low-altitude areas, achieving better sleep and rest conditions. The safety protection of internal gas pressure and the monitoring and control of key gas concentrations such as oxygen and carbon dioxide are feasible, safe, and reliable, with reasonable redundancy configuration fully considered.

[0122] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
