Description

Technical Field

[0001] This application belongs to the field of saturated diving environmental control, specifically relating to a gas analysis system for a living quarters. Background Technology

[0002] Mobile saturation diving systems are primarily used for deep-sea diving operations, such as submarine rescue, emergency rescue, and salvage missions. These systems typically consist of multiple modules, including a living quarters module, a diving bell module, a deployment module, a centralized operation and control module, a life support equipment module, an emergency high-pressure escape chamber module, a support equipment module, and a gas supply module (optional). The saturation living quarters, serving as the diver's primary working and living space, provide the necessary gas supply and life support during deep-sea diving operations. The ambient gases within the living quarters and transition chambers must be monitored by a dedicated gas analysis system to ensure that oxygen and carbon dioxide concentrations meet safety requirements. Traditionally, these gas analysis systems use sampling ports and gas sampling pipelines to deliver gas samples from within the chamber, after depressurization, to oxygen and carbon dioxide analyzers for concentration analysis. Current gas analysis technologies mainly rely on fixed sampling pipelines and sensor equipment, sending gas samples to analytical instruments for testing through sampling ports located at different positions within the living quarters.

[0003] While existing saturation diving systems can monitor cabin gases using gas analyzers, the distribution of gases within the living quarters is typically uneven due to high pressure and complex airflow. Traditional gas sampling methods, which transmit samples through tubing to the analyzer, cannot effectively and comprehensively reflect the differences in oxygen and carbon dioxide concentrations across different areas of the cabin. A single gas sampling point may fail to capture dynamic changes in the cabin's gas concentration, especially in confined environments where local concentrations can differ significantly from the overall concentration. Traditional sampling systems cannot provide enough sampling points to cover all critical areas. This makes existing monitoring systems unable to accurately predict potential gas concentration problems in certain situations, potentially posing safety hazards. Furthermore, the gas analysis sampling tubing systems used in existing technologies are relatively simple, lacking dynamic monitoring of cabin gas distribution and unable to achieve refined management and real-time adjustments. Therefore, relying on fixed tubing and sampling points for gas monitoring has significant limitations, especially in complex environments with uneven gas flow, making it difficult to provide accurate and comprehensive monitoring results, impacting diver safety and operational efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a gas analysis system for a living quarters, aiming to solve the problem that traditional gas monitoring methods cannot accurately reflect the uneven gas distribution within the cabin. This system combines movable sensor components and a gas analyzer to achieve dynamic monitoring of gas concentrations in multiple areas within the living quarters, enabling more comprehensive and real-time acquisition of oxygen and carbon dioxide distribution, thereby improving the accuracy and reliability of gas concentration monitoring.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A gas analysis system for a habitation cabin includes a habitation cabin body, a gas supply assembly, a sensor assembly, a sampling tube, a gas analyzer, and a controller. The gas supply assembly includes a compressed oxygen source, a pressure reducing valve, and an air supply module. Compressed oxygen from the compressed oxygen source is depressurized by the pressure reducing valve and then flows into the habitation cabin body through the air supply module. The air supply module includes a main air outlet connected to the compressed oxygen source, located on the top of the habitation cabin body.

The gas supply assembly includes a compressed oxygen source, a pressure reducing valve, and an air supply module. The compressed oxygen source is depressurized by the pressure reducing valve and then flows into the habitation cabin body through the ... The device assembly includes an oxygen sensor, a carbon dioxide sensor, a moving part, and a track. The track is laid along the straight air duct and the air supply branch pipe. The oxygen sensor and the carbon dioxide sensor are mounted on the moving part, which cooperates with the track and can move along the track. The sampling tube includes a top sampling port, a bottom sampling port, and a three-way valve disposed on the main body of the living quarters. The two air inlets of the three-way valve are respectively connected to the top sampling port and the bottom sampling port for switching the sampling port. The air outlet of the three-way valve is connected to a gas analyzer, which includes an oxygen analysis module and a carbon dioxide analysis module. The controller acquires and compares the data from the sensor assembly and the gas analyzer.

[0007] Preferably, the system further includes an exhaust assembly, which includes exhaust pipes arranged along the length of the living compartment body on both sides near the bottom of the living compartment body. The exhaust pipes have multiple exhaust ends evenly distributed on them, and the exhaust pipes are connected to the main exhaust port that connects the inside and outside of the living compartment body through an annular pipe.

[0008] Preferably, the moving part includes an electric roller and a drive motor, the drive motor drives the electric roller to move along the track, and the oxygen sensor and carbon dioxide sensor transmit the detected gas concentration data to the controller in real time through a wireless communication module.

[0009] Preferably, the controller includes a data storage module for recording historical gas concentration data acquired by the gas analyzer and sensor components, and predicting the changing trends of oxygen and carbon dioxide concentrations based on an analysis model.

[0010] Preferably, the controller includes a correction module for dynamically correcting the gas concentration data obtained by the sampling tube and the gas analyzer based on the gas concentration data detected by the sensor components, and generating an optimized result.

[0011] Preferably, the controller includes an alarm module that triggers an audible and visual alarm and adjusts the operating status of the gas supply component when any data from the sensor assembly and the gas analyzer exceeds a preset threshold.

[0012] Preferably, the controller includes a data display module that generates a gas distribution map based on gas concentration data detected by the sensor components and the gas analyzer, thereby visualizing the distribution of oxygen and carbon dioxide inside the cabin.

[0013] Preferably, the moving part includes a cleaning device for cleaning the air supply terminal. When the oxygen sensor detects an abnormality in the oxygen concentration data of any air supply terminal, the cleaning device is activated to clean the air supply terminal.

[0014] Preferably, the cleaning device includes a flexible electrostatic brush and a mounting rod, wherein the flexible electrostatic brush is detachably inserted into the movable part via the mounting rod.

[0015] Preferably, the air supply terminal is an orifice plate, diffuser, or grille vent, and a shut-off valve, a pressure reducing valve, and a water separator are provided between the gas analyzer and the three-way valve.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) This invention achieves comprehensive monitoring and dynamic correction of gas distribution within the living quarters by combining a movable sensor assembly with a fixed gas analyzer. Compared to methods relying solely on a single detection method, this invention utilizes both the stability and high precision of the fixed sampling pipeline and provides multi-point real-time dynamic data through the movable sensor assembly, thereby ensuring more accurate, reliable, and comprehensive monitoring results. Simultaneously, the controller can analyze and store multi-point monitoring data, not only dynamically correcting the monitoring results but also generating gas distribution maps to achieve real-time visualization of the gas state, thus improving the system's intelligence and safety.

[0018] (2) This invention makes full use of the pipeline structure of the air supply module and lays a track in the pipeline so that the sensor component can move along the track. The structure is simple and compact, easy to arrange and maintain, and reduces cost and implementation difficulty. At the same time, the sensor component can not only monitor the gas distribution at the air supply terminal along the track, but also obtain the working status of each air supply terminal in real time. It can also automatically start the cleaning device when abnormal gas concentration is detected to maintain the air supply terminal, ensuring oxygen supply uniformity and equipment operation stability. This design integrates detection and maintenance functions, improves the level of automation and intelligent maintenance capabilities, effectively reduces manual maintenance costs and extends equipment service life.

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see Figure 1-5 This embodiment provides a gas analysis system for a habitation cabin, including a habitation cabin body 1, a gas supply assembly 2, a sensor assembly 3, a sampling tube 4, a gas analyzer 5, and a controller 6. The system supplies compressed oxygen to the habitation cabin body 1 through the gas supply assembly 2, while simultaneously monitoring and analyzing the oxygen and carbon dioxide concentrations within the cabin to ensure a safe and stable environment. The gas supply assembly 2 includes a compressed oxygen source 21, a pressure reducing valve 22, and an air supply module 23. The compressed oxygen source 21 provides high-pressure oxygen. After the pressure reducing valve 22 reduces the oxygen pressure to suit the working environment inside the habitation cabin body 1, it is then evenly delivered to the habitation cabin body 1 via the air supply module 23.

[0030] The air supply module 23 includes a main air outlet 24 located on the top of the living quarters 1 and connected to a compressed oxygen source 21. The main air outlet 24 serves as the starting point for oxygen delivery, delivering oxygen through a straight duct 25 to multiple annularly arranged branch air ducts 26. The straight duct 25 runs along the top of the living quarters 1, providing a delivery channel for the branch air ducts 26, which extend from the top of the living quarters 1 along the sidewalls to the lower middle side of the living quarters 1, ensuring oxygen coverage of the entire interior space. Several air supply terminals 27 are arranged on the side of the branch air ducts 26 facing the interior of the living quarters 1. These terminals 27 can employ perforated plates, diffusers, or grille structures to ensure uniform oxygen distribution within the cabin and avoid localized gas concentration deviations.

[0031] Sensor assembly 3 includes an oxygen sensor 31, a carbon dioxide sensor 32, a moving part 33, and a track 34. The track 34 is laid along the straight duct 25 and the air supply branch duct 26, providing a movement path for the moving part 33 to monitor gas concentrations in different areas. The oxygen sensor 31 and carbon dioxide sensor 32 are mounted on the moving part 33, which can move along the track 34. By moving along the air supply duct, it can detect oxygen and carbon dioxide concentrations at multiple locations in real time.

[0032] The sampling tube 4 includes a top sampling port 41 at the top of the living quarters 1 and a bottom sampling port 42 at the bottom, with the switching of the sampling ports controlled by a three-way valve 43. The top sampling port 41 is used to collect gas from the top area of ​​the cabin, and the bottom sampling port 42 is used to collect gas from the bottom area of ​​the cabin, thus covering the gas distribution at different heights within the cabin. The two inlets of the three-way valve 43 are connected to the top sampling port 41 and the bottom sampling port 42, respectively, while the outlet is connected to the gas analyzer 5. The gas analyzer 5 includes an oxygen analysis module and a carbon dioxide analysis module, which can analyze the oxygen and carbon dioxide content of the sampled gas respectively, providing real-time monitoring data to the controller 6.

[0033] The controller 6 acquires and compares the detection data from the sensor assembly 3 and the gas analyzer 5. By comparing the dynamic detection data of the sensor assembly 3 with the fixed monitoring data of the sampling tube 4, the controller 6 can generate a more accurate gas concentration distribution and record historical data through data analysis and storage functions. Simultaneously, the controller 6 can generate a gas distribution map to display the real-time distribution of oxygen and carbon dioxide within the chamber, improving the level of visual management of the gas environment.

[0034] This embodiment also includes an exhaust assembly 7, which includes exhaust pipes 71 arranged along the length of the living compartment body 1 on both sides near the bottom. The arrangement of the exhaust pipes 71 allows them to cover the lower airflow area inside the compartment, facilitating the removal of gas and impurities accumulated at the bottom and ensuring the uniformity and flow of air circulation within the compartment. Multiple exhaust terminals 72 are evenly distributed on the exhaust pipes 71. The exhaust terminals 72 are arranged at reasonable intervals to achieve a uniform distribution of exhaust flow and velocity, thereby avoiding the problem of abnormal concentration caused by localized gas accumulation. The exhaust pipes 71 are connected to the main exhaust port 74, which is connected to both the inside and outside of the living compartment body 1, via an annular pipe 73. The design of the annular pipe 73 reduces pressure loss in the exhaust path and improves exhaust efficiency. Meanwhile, the main exhaust port 74 serves as a gas discharge outlet, maintaining unobstructed connection with the outside of the compartment, allowing exhaust gas to be quickly discharged and effectively maintaining a fresh and safe air environment inside the compartment.

[0035] The moving part 33 includes electric rollers and a drive motor, which drives the electric rollers to move along the track 34. The electric rollers are arranged on the track 34 and operate smoothly in conjunction with it. At the connection points of the straight air duct 25 and the air supply branch pipe 26, corresponding to points on the track 34, the electric rollers can turn, ensuring that the sensor assembly 3 can move along different air supply branch pipes 26, achieving detection coverage of each air supply branch pipe 26 and further improving the comprehensiveness and accuracy of monitoring. The oxygen sensor 31 and carbon dioxide sensor 32 are mounted on the moving part 33 and interact with the controller 6 via a wireless communication module. They can transmit the detected gas concentration data to the controller 6 in real time. The application of the wireless communication module eliminates the need for complex cable connections during the movement of the sensor assembly 3, improving operational flexibility and reducing maintenance difficulty and system complexity. Simultaneously, the mobile monitoring of the sensor assembly 3 can be combined with the fixed monitoring of the sampling tube 4. Through the analysis and comparison functions of the controller 6, dynamic adjustment and optimization analysis of the gas distribution inside the chamber can be achieved, ensuring that the gas environment inside the chamber remains in a safe and stable state.

[0036] The controller 6 includes a data storage module for recording historical gas concentration data acquired by the gas analyzer 5 and sensor assembly 3. This module can classify and store the collected gas concentration data by time period and supports long-term data accumulation and analysis, allowing operators to understand changes in oxygen and carbon dioxide concentrations within the chamber through historical data trends. Simultaneously, the controller 6 predicts trends in oxygen and carbon dioxide concentrations based on an analytical model. By analyzing the correlation between historical and real-time monitoring data using algorithms, it provides predictive results for gas concentration regulation, enabling proactive adjustment measures to ensure the stability of the chamber's gas environment.

[0037] The controller 6 also includes a correction module, which dynamically corrects the gas concentration data obtained by the sampling tube 4 and the gas analyzer 5 based on the gas concentration data detected by the sensor component 3. The correction module can automatically calculate the error and compensate by comparing the data differences between the sensor component 3 and the sampling tube 4, thereby generating more accurate optimization results and improving the accuracy of gas analysis.

[0038] In practical applications, the correction module of controller 6 dynamically corrects the gas concentration data to ensure the accuracy and reliability of the monitoring results. For example, during a certain detection process, gas analyzer 5 detects an oxygen concentration of φ1 through the top sampling port 41 of sampling tube 4 and an oxygen concentration of φ2 through the bottom sampling port 42. Simultaneously, sensor assembly 3 moves along track 34 and calculates the average concentration φ3 from the oxygen concentration data measured by oxygen sensor 31 at multiple detection points. Since the sampling data φ1 and φ2 from sampling tube 4 only reflect the concentration distribution at fixed sampling points, while the average concentration φ3 of sensor assembly 3 can cover a wider area, the combination of the two can further improve the accuracy of data analysis.

[0039] The correction module of controller 6 first performs linear interpolation on φ1 and φ2 to calculate the theoretical average concentration φ4, using the following formula:

[0040]

[0041] Then, the correction module compares φ4 with the average concentration φ3 detected by sensor component 3 and calculates the error Δφ between the two:

[0042]

[0043] Based on the error Δφ, the controller 6 determines whether the detection data of the gas analyzer 5 needs correction. If Δφ exceeds the preset threshold ε, the analysis result of the sampling tube 4 is considered to have a deviation, and the correction module dynamically compensates for φ1 and φ2 based on Δφ. For example, the correction module can adjust the weight ratio of φ1 and φ2 so that the final corrected concentration result φ5 is closer to φ3, as shown in the formula:

[0044]

[0045] Where k is a correction coefficient, dynamically calculated by controller 6 based on historical data and environmental characteristics. Based on this, controller 6 uses the corrected concentration result φ5 as the final gas concentration, which is further used for oxygen supply control of gas supply component 2 and threshold judgment of the alarm module.

[0046] For example, gas analyzer 5 detects an oxygen concentration of φ1=18.0% through the top sampling port 41 of sampling tube 4 and an oxygen concentration of φ2=23.0% through the bottom sampling port 42. Simultaneously, sensor assembly 3 moves along track 34 and the average oxygen concentration measured by oxygen sensor 31 at multiple detection points is φ3=21.0%. Since the sampling data φ1 and φ2 from sampling tube 4 only reflect the concentration distribution at fixed sampling points, while the average concentration φ3 from sensor assembly 3 can cover a wider area, combining the two can further improve the accuracy of data analysis. The correction module of controller 6 first performs linear interpolation on φ1 and φ2 to calculate the theoretical average concentration φ4=20.5%. Then, the correction module compares φ4 with the average concentration φ3 detected by sensor assembly 3 and calculates the error Δφ=0.5%. Based on the error Δφ, controller 6 determines whether the detection data of gas analyzer 5 needs correction. If Δφ exceeds the preset threshold ε (e.g., 0.2%), the analysis results of sampling tube 4 are considered to be biased. The correction module dynamically compensates for φ1 and φ2 based on Δφ. Assuming k=0.6, the calculated φ5=0.6×20.5%+0.4×21.0%=20.7%. At this point, controller 6 uses 20.7% as the final concentration data and sends an adjustment command to gas supply component 2 to adjust the oxygen supply or exhaust speed, ensuring that the oxygen concentration gradually returns to the preset safe range. Through this correction process, controller 6 can dynamically correct the deviation between fixed sampling and mobile detection, ensuring the accuracy and real-time performance of gas concentration monitoring, and further improving the safety management level of the cabin gas environment.

[0047] Furthermore, the controller 6 includes an alarm module. When any data from the sensor assembly 3 and the gas analyzer 5 exceeds a preset threshold, an audible and visual alarm is triggered to alert the operator. Simultaneously, in conjunction with the gas supply assembly 2, the controller automatically adjusts the oxygen supply of the compressed oxygen source 21 or stops the gas supply of the air supply module 23 to quickly restore the gas concentration inside the chamber to a safe range, ensuring personnel safety. The controller 6 also includes a data display module. Based on the gas concentration data detected by the sensor assembly 3 and the gas analyzer 5, the controller generates a gas distribution map. The data display module can display the generated gas distribution map on a screen in two-dimensional or three-dimensional graphic form, making the distribution status of oxygen and carbon dioxide inside the chamber intuitively visible. Operators can analyze changes in gas distribution based on real-time graphics and adjust the gas supply strategy or exhaust scheme in a timely manner, improving the intelligence level and ease of operation of environmental management.

[0048] Furthermore, the moving part 33 includes a cleaning device 35 for cleaning the air supply terminals 27. When the oxygen sensor 31 detects an abnormality in the oxygen concentration data of any air supply terminal 27, the controller 6 automatically activates the cleaning device 35 to clean the air supply terminal 27. If the concentration data monitored by the oxygen sensor 31 deviates from the normal range, the controller 6 will determine that there may be dust or blockage in the air supply terminal 27, affecting the uniform distribution of oxygen. Therefore, it will activate the cleaning device 35 to perform a cleaning operation, ensuring the normal working condition of the air supply terminals. The cleaning device 35 includes a flexible electrostatic brush 351 and a mounting rod 352. The flexible electrostatic brush 351 is used to clean dust and particulate matter on the air supply terminal 27 by electrostatic adsorption, preventing dust from spreading into the cabin and maintaining air quality. The mounting rod 352 allows the flexible electrostatic brush 351 to be securely inserted into the moving part 33 and is easy to disassemble and replace when needed, ensuring long-term use and convenient maintenance of the cleaning device. With this design, the cleaning device 35 can respond quickly and automatically clean when the oxygen concentration is abnormal, avoiding uneven oxygen supply or abnormal concentration caused by blockage at the air supply end, thus improving the automation level and reliability of the system.

[0049] Furthermore, the flexible electrostatic brush 351 can be equipped with a water storage tank 353 at its end, which can store clean water. When the air supply terminal 27 needs cleaning, the controller 6 automatically activates the cleaning device 35. The flexible electrostatic brush 351 removes dust and particulate matter from the air supply terminal 27 through electrostatic adsorption. At the same time, water in the water storage tank 353 can flow out along the brush, further enhancing the cleaning effect. The water flow is evenly distributed on the air supply terminal 27 through the end of the brush, helping to remove dust and dirt and improving cleaning efficiency. On the other hand, the gas analyzer 5 includes a humidity monitoring module. When the humidity monitoring module detects that the humidity inside the living chamber 1 is too low, water in the water storage tank 353 will flow out along the brush and spray water onto the air supply terminal 27, moistening the gas flowing out through the air supply terminal 27. This design not only improves the cleaning effect but also effectively increases the humidity of the air inside the chamber, improving the gas humidification effect and ensuring that the gas environment inside the living chamber is within a suitable humidity range, avoiding the impact of low humidity on the comfort and health of divers. With this integrated cleaning and humidification design, the cleaning device 35 can improve the performance and usability of the living quarters gas analysis system in multiple ways.

[0050] In this embodiment, a shut-off valve, a pressure reducing valve, and a water eliminator are installed between the gas analyzer 5 and the three-way valve 43. The shut-off valve controls the gas flow rate, ensuring accurate flow regulation before the gas enters the gas analyzer 5 and preventing inaccurate analysis results due to excessive or insufficient gas flow. The pressure reducing valve regulates the gas pressure entering the gas analyzer 5, adjusting it to a suitable range to meet the analyzer's operating requirements and preventing excessive pressure from affecting measurement accuracy or causing equipment damage. The water eliminator removes moisture from the gas entering the gas analyzer 5, preventing moisture from affecting the accuracy of analysis results or corroding electronic components. The coordinated use of these three devices ensures the normal and stable operation of the gas analyzer 5 and improves the accuracy and reliability of gas analysis.

[0051] In some embodiments, multiple sensor components 3 can be used. Compared to using only one sensor component 3, multiple sensor components 3 can acquire the gas distribution within the living quarters 1 more quickly, thereby improving monitoring efficiency and accuracy. Each sensor component 3 moves along the track 34, covering different locations within the cabin to achieve comprehensive monitoring of gas concentration. However, since multiple sensor components 3 move along the track 34, their movement paths must be rationally planned to avoid collisions or congestion. Through precise movement path design and scheduling, each sensor component 3 can move independently and smoothly, avoiding interference between different sensor components 3. Furthermore, multiple sensor components 3 can transmit data and coordinate their work through a wireless communication module, ensuring they can independently and smoothly complete the gas concentration monitoring task simultaneously, ensuring data accuracy and system stability.

[0052] In summary, this invention discloses a gas analysis system for a living quarters. This system, by combining movable sensor components and a gas analyzer, achieves comprehensive and real-time monitoring of oxygen and carbon dioxide concentrations within the living quarters. By accurately measuring the gas distribution within the cabin, the system solves the problem of insufficient comprehensive gas concentration monitoring under traditional single-detection methods, ensuring the accuracy and reliability of gas analysis. Furthermore, the system uses a dynamic correction module to correct gas concentration data, providing more accurate results, and maintains the air supply terminals through a cleaning device, further improving system stability and maintainability. This invention innovatively combines fixed sampling and mobile monitoring methods, improving the accuracy of gas monitoring and providing powerful functions in real-time data correction, dynamic adjustment of gas concentration, and visualization of gas distribution. In addition, the system adopts a simple and efficient pipeline structure design, combined with an automatic cleaning function, reducing the need for manual maintenance and enhancing the system's automation and intelligence level.

[0053] The technical solution of this invention provides an innovative solution for the field of gas analysis in living quarters. It not only effectively improves the management capability of the gas environment inside the cabin, but also provides a valuable reference for gas monitoring technology in high-risk and high-precision environments such as deep-sea diving and space exploration. The application of this system will greatly promote technological progress and safety assurance in this field, and has broad market prospects and important practical significance.
