It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Figure 1 This is a schematic diagram of a differential pressure control system for a compartment according to an embodiment of the present invention. (Refer to...) Figure 1 The embodiments of the present invention provide a cabin pressure differential control system, which includes: a comprehensive control console 10, a sub-control box 20, a data acquisition box 30, a fan device 41, an airtight door monitoring device 42, a regional pressure monitoring box 43, a pressure differential control valve group 44, an airtight ventilation butterfly valve 45, a cabin air pressure field temperature and humidity detection device 46, and a door and window opening and closing status detection device 47.

[0041] The data acquisition box 30 is connected to the fan equipment 41, the airtight door monitoring equipment 42, the area pressure monitoring box 43, the differential pressure control valve group 44, the airtight ventilation butterfly valve 45, the cabin air pressure field temperature and humidity detection equipment 46, and the door and window opening and closing status detection equipment 47. The cabin air pressure field temperature and humidity detection equipment 46 is used to send the temperature and humidity data inside the cabin to the data acquisition box 30. The door and window opening and closing status detection equipment 47 is used to send the door and window opening and closing status information to the data acquisition box 30. The airtight door monitoring equipment 42 is used to send the opening and closing status information of the airtight door to the data acquisition box 30. The area pressure monitoring box 43 is used to send the air pressure data inside the cabin to the data acquisition box 30. The data acquisition box 30 is used to send the received data and information to the integrated control console 10 through the sub-control box 20.

[0042] The data acquisition box 30 is connected in sequence to the sub-control box 20 and the integrated control console 10. The integrated control console 10 is used to analyze and process the received data and information, and send control commands to the sub-control box 20. The sub-control box 20 is used to send one-key control, zone one-key control and single control commands to the differential pressure control valve group 44, the airtight ventilation butterfly valve 45 and the fan equipment 41 according to the control commands. The differential pressure control valve group 44, the airtight ventilation butterfly valve 45 and the fan equipment 41 respond to the one-key control, zone one-key control and single control commands to comprehensively regulate and control the differential pressure of the compartment.

[0043] Specifically, the integrated cabin pressure control system is based on the integrated control console 10. The integrated control console 10 can be a set of integrated control software using a B / S architecture to control various pressure facilities in the cabin. Users send control commands to the sub-control boxes 20 through the integrated control software. The sub-control boxes 20 send one-key control, zone one-key control, and single control commands to the downstream filter adsorption device, differential pressure control valve group 44, airtight ventilation butterfly valve 45, air conditioner, and fan equipment 41. Users can perform centralized protection, normal operation, and initial operation on the controlled equipment (i.e., the whole ship pressure-maintaining equipment, the equipment in a certain protected area, or a single device) according to the actual situation. At the same time, it receives monitoring data (such as air pressure, temperature, humidity, doors and windows, etc.) and status information from the downstream equipment to achieve integrated control of cabin pressure.

[0044] The integrated control console 10 communicates with the sub-control boxes 20 via Ethernet to achieve remote centralized control and information display of each protected area. The sub-control boxes 20, based on proximity, control several data acquisition boxes 30 via CAN communication to send control commands to lower-level devices and collect device data. The data acquisition boxes 30 use serial communication, CAN communication, and I / O interfaces to collect data from the underlying devices.

[0045] The integrated control console 10 can be composed of two standardized second-generation consoles. It can ensure that if any one integrated control console 10 fails, the redundancy function of the entire control system will not be affected. At the same time, it takes into account the working conditions of multiple systems, multiple areas, and multiple tasks in the centralized defense state. Users can use one-button control, zone one-button control, and single control commands to perform monitoring of air conditioners, fans, filter adsorption devices, differential pressure control valve groups, airtight equipment, and cabin (area) air pressure field temperature and humidity monitoring in the entire ship's protected area.

[0046] Data acquisition boxes 30 are deployed near the ship's protected area and collect data and signals detected by lower-level devices through interfaces such as serial ports, CAN, and IO. These lower-level devices include: fan equipment 41, airtight door monitoring equipment 42, filter adsorption devices, area pressure monitoring boxes 43, differential pressure control valve groups 44, airtight ventilation butterfly valves 45, cabin air pressure field temperature and humidity detection equipment 46, and door and window opening / closing status detection equipment 47.

[0047] The differential pressure control valve assembly 44 requires no external energy source, relying on the pressure changes of the regulated medium itself for automatic adjustment, maintaining a constant pressure difference between the user's inlet and outlet. It is particularly suitable for individual metering or automatic control systems, contributing to stable system operation. In a ship's ventilation system, the airtight ventilation butterfly valve 45 is used to regulate the airflow and direction of the ventilation ducts. By controlling the valve's opening, ventilation can be adjusted in different areas, ensuring air circulation and air quality within the ship.

[0048] Figure 2 This is a schematic diagram of the structure of an integrated control console provided according to an embodiment of the present invention. Figure 3 This is a schematic diagram of a sub-control box according to an embodiment of the present invention. Figure 4 This is a structural schematic diagram of a data acquisition box according to an embodiment of the present invention, with reference to... Figure 2 , Figure 3 and Figure 4 The compartment differential pressure control system consists of a central control console, sub-control boxes, data acquisition boxes, airtight door monitoring equipment, area pressure monitoring boxes, and overpressure control boxes. With compartment pressure maintenance as its core objective, the system encompasses comprehensive monitoring functions for air conditioning, filtration and adsorption, differential pressure control, airtight door monitoring and alerts, and air pressure control equipment. It is a comprehensive control facility that ensures the orderly operation of management tasks such as air pressure monitoring, disinfection monitoring, and flow direction management.

[0049] The differential pressure control system can also determine the required differential pressure value based on the size and shape of the compartment; select appropriate fans and air volume regulating devices based on the differential pressure value; design a reasonable air duct layout to achieve uniform pressure distribution; and optimize system parameters through simulation and experimental verification to ensure stable system operation.

[0050] The technical solution of this invention uses cabin pressure field temperature and humidity detection equipment, door and window opening and closing status detection equipment, airtight door monitoring equipment, and area pressure monitoring box to send relevant data and signals from inside the cabin to a data acquisition box. The data acquisition box sends the received data and information to the integrated control console through a sub-control box. The integrated control console analyzes and processes the received data and information and sends control commands to the sub-control boxes. The sub-control boxes send one-key control, zone one-key control, and single-control commands to the differential pressure control valve group, airtight ventilation butterfly valve, and fan equipment according to the control commands. The differential pressure control valve group, airtight ventilation butterfly valve, and fan equipment respond to the one-key control, zone one-key control, and single-control commands to comprehensively regulate and control the differential pressure in the cabin. The above operation simplifies the system design process, improves the system's economic efficiency, improves the system's stability, and facilitates crew operation. It solves the problems of low automation, poor system stability, high system complexity, and inconvenience for crew operation in existing cabin differential pressure control systems. It achieves the effect of improving the automation level of cabin differential pressure control and improving system stability, thereby ensuring that crew members can work normally and are protected from external environmental hazards.

[0051] Figure 5 This is a schematic diagram of another compartment differential pressure control system provided according to an embodiment of the present invention, with reference to... Figure 5 Optionally, the differential pressure control system also includes: an overpressure control box 48;

[0052] The overpressure control box 48 is connected to the area pressure monitoring box 43. The overpressure control box 48 is used to monitor the pressure value and automatically cut off the power supply or activate the protection mechanism to protect the equipment in the system from damage caused by excessive pressure.

[0053] Specifically, the ship's overpressure control box is mainly used to control the ship's internal pressure system, preventing equipment damage or safety accidents caused by abnormal pressure. Its core functions include:

[0054] Pressure monitoring and alarm: Real-time monitoring of system pressure values; when the pressure exceeds a set threshold, an alarm signal is triggered to alert the operator to perform an emergency shutdown. When the pressure abnormally rises to a dangerous level, the power or gas supply to the relevant equipment is automatically cut off to prevent further pressure increases that could lead to serious consequences such as explosions.

[0055] Linked protection mechanism: It is linked with other safety systems on the ship (such as fire extinguishing system and ventilation system), for example, to activate the carbon dioxide fire extinguishing device or shut down the fan to reduce the pressure when the pressure is too high.

[0056] Remote control and data transmission: Supports remote monitoring and manual control, facilitating adjustment of the pressure system from the cab or shore-based management center, while uploading real-time data to the management system.

[0057] In addition, the overpressure control box is also used to provide the data acquisition box with switch position signals, valve opening signals, and comprehensive fault signals.

[0058] Continue to refer to Figure 5 Optionally, the cabin differential pressure control system also includes: an air conditioner 49;

[0059] Air conditioner 49 is connected to sub-control box 20. Air conditioner 49 is used to regulate the temperature, humidity and cleanliness of the cabin air and maintain the positive pressure environment of the cabin.

[0060] Specifically, marine air conditioners are specialized devices used for regulating the environment of ship cabins. They ensure the comfort of crew and passengers by controlling air temperature, humidity, and cleanliness, and provide a suitable working environment for shipboard equipment. The main functions of air conditioners in ship cabins include regulating temperature and humidity, air filtration and purification, maintaining positive pressure in the cabin, and ensuring a suitable operating environment for equipment.

[0061] Temperature and humidity regulation: Marine air conditioners regulate cabin temperature through cooling and heating functions to adapt to high-temperature or cold sea environments. For example, in tropical hot and humid areas, cooling and dehumidification are required; in polar cold seas, heating and insulation are required.

[0062] Air filtration and purification: For air containing salt mist, oil mist, or odors, air conditioners are equipped with filters to remove pollutants and keep the air clean.

[0063] Maintaining positive pressure in the compartment: In hazardous areas such as cargo holds, the air conditioning system prevents harmful gases from seeping in by controlling the air pressure in the compartment to be higher than that outside.

[0064] Ensure a safe operating environment for equipment: Precision instrument compartments require constant temperature and humidity to prevent corrosion or malfunction of electronic equipment due to moisture or temperature differences.

[0065] Continue to refer to Figure 5 Optionally, the airtight door monitoring device 42 includes: an airtight door centralized control box and an airtight door indicator light panel that are interconnected;

[0066] The centralized control box for airtight doors is used to control the indicator light panel of the airtight doors according to the centralized control command issued by the integrated control console 10 or the sub-control box 20.

[0067] The airtight door indicator panel is used to indicate whether opening the door is permitted or prohibited based on the control of the airtight door centralized control box, prompting the user to indicate the current operating permissions of the airtight door in the centralized protection state.

[0068] Specifically, the airtight door monitoring device 42 consists of an airtight door centralized control box and an airtight door indicator light panel. The airtight door centralized control box controls the airtight door indicator light panel according to the centralized control command issued by the integrated control console or sub-control box. The airtight door indicator light panel indicates whether opening is permitted or prohibited according to the control of the airtight door centralized control box, prompting the user to indicate the operating permissions of the airtight door under centralized control status.

[0069] Continue to refer to Figure 5 Optionally, the chamber differential pressure control system also includes: a filter adsorption device 50;

[0070] The filter adsorption device 50 is connected to the data acquisition box 30. The filter adsorption device 50 is used to purify the air in the cabin while maintaining the air quality in accordance with safety standards through the synergistic effect of adsorption, catalysis and filtration.

[0071] Specifically, the filtration and adsorption devices in the cabin are primarily used for air purification, with air purification as their core function. Through the synergistic action of adsorption, catalysis, and filtration: adsorption: highly efficient activated carbon adsorbs odors and trace amounts of harmful gases in the cabin; catalysis: anhydrous lithium hydroxide absorbs water vapor and catalyzes the decomposition of carbon dioxide; filtration: ultra-fine glass fiber or synthetic fiber filters out harmful particles such as dust and aerosols. This ensures a healthy cabin environment, effectively removes air pollutants, avoids health threats to the crew, and maintains cabin air quality that meets safety standards.

[0072] Optionally, the number of sub-control boxes is at least 5;

[0073] Each sub-control box corresponds to a protection zone, and the sub-control boxes are used to realize the zone control and status acquisition and display of different protection zones.

[0074] Specifically, each sub-control box consists of five standardized B1 boxes, with each box corresponding to a protected zone. The sub-control boxes enable zoned control and status acquisition and display for different centralized protection zones. Users can send corresponding control commands to the controlled devices in subordinate zones via the "Centralized Protection," "Normal," and "Initial" buttons, setting the controlled devices to the corresponding operating conditions. The controlled devices then execute corresponding operations based on these conditions. Each controlled device determines the operating condition switching result; if the switching fails, an alarm is triggered. During operating condition switching, if any underlying device malfunctions, the user is prompted to troubleshoot the fault before proceeding with the switch.

[0075] Continue to refer to Figure 5 Optionally, the differential pressure control system may also include: power supply equipment;

[0076] The power supply equipment is connected to the integrated control console 10 and the sub-control box 20, and is used to provide power to the integrated control console 10 and the sub-control box 20.

[0077] Specifically, the power supply equipment provides AC220V power to the integrated control console 10 and the sub-control box 20, and the sub-control box 20 provides DC24V power to the data acquisition box 30.

[0078] Figure 6 This is a flowchart of a control method for a differential pressure control system for a compartment according to an embodiment of the present invention, with reference to... Figure 6 The present invention also provides a control method for a differential pressure control system, which is applied to the differential pressure control system in the embodiments of the present invention. The control method for the differential pressure control system includes the following steps:

[0079] S110. The cabin air pressure field temperature and humidity detection equipment sends the temperature and humidity data of the cabin to the data acquisition box. The door and window opening and closing status detection equipment sends the door and window opening and closing status information to the data acquisition box. The airtight door monitoring equipment sends the airtight door opening and closing status information to the data acquisition box. The area pressure monitoring box sends the cabin air pressure data to the data acquisition box. The data acquisition box sends the received data and information to the integrated control console through the sub-control box.

[0080] Specifically, in combination Figure 1 The data acquisition box 30 is deployed near the entire ship's protected area, collecting data and signals detected by lower-level devices through interfaces such as serial port, CAN, and IO. For example, the lower-level devices include: fan equipment 41, airtight door monitoring equipment 42, filter adsorption device, area pressure monitoring box 43, differential pressure control valve group 44, airtight ventilation butterfly valve 45, cabin air pressure field temperature and humidity detection equipment 46, and door and window opening and closing status detection equipment 47.

[0081] S120: The received data and information are analyzed and processed through the integrated control console, and control commands are sent to the sub-control boxes. The sub-control boxes are used to send one-key control, zone one-key control and single control commands to the differential pressure control valve group, airtight ventilation butterfly valve and fan equipment according to the control commands. The differential pressure control valve group, airtight ventilation butterfly valve and fan equipment respond to the one-key control, zone one-key control and single control commands to comprehensively regulate and control the differential pressure of the compartment.

[0082] Specifically, in combination Figure 1The integrated cabin pressure control system is based on the integrated control console 10. The integrated control console 10 can be a set of integrated control software using a B / S architecture to control various pressure facilities in the cabin. Users send control commands to the sub-control boxes 20 through the integrated control software. The sub-control boxes 20 send one-key control, zone one-key control, and single control commands to the downstream filter adsorption device, differential pressure control valve group 44, airtight ventilation butterfly valve 45, air conditioner, and fan equipment 41. Users can perform centralized protection, normal operation, and initial operation on the controlled equipment (i.e., the whole ship pressure-maintaining equipment, the equipment in a certain protected area, or a single device) according to the actual situation. At the same time, it receives monitoring data (such as air pressure, temperature, humidity, doors and windows, etc.) and status information from the downstream equipment to achieve integrated control of cabin pressure.
