[0014] Specifically, in the embodiments of this application, the gas supply simulation training system is a comprehensive multi-training system built after a thorough investigation of almost all gas supply systems in the shipbuilding and aviation industries, and after in-depth research and analysis of the commonality between these gas supply systems used in the shipbuilding and aerospace industries. Furthermore, based on the principles of various different gas supply subsystems, the gas supply pipeline structure of the main functional sections is simplified to facilitate the connection and construction of various simulation training systems.

[0015] More specifically, in this embodiment, the gas supply simulation training system mainly includes five systems: an oxygen-nitrogen integrated gas supply simulation training system, an oxygen cylinder chamber simulation training system, a nitrogen cylinder chamber simulation training system, an oxygen supply terminal simulation training system, and a nitrogen supply terminal simulation training system. Optionally, an aviation oxygen filling equipment simulation training system, a compressed air supply terminal simulation training system, and an aviation air conditioning equipment simulation training system can be further introduced to form a more comprehensive eight-system simulation training system.

[0016] In the embodiments of this application, each simulation training system is connected to the control system; the oxygen cylinder simulation training system and the nitrogen cylinder simulation training system are respectively connected to the oxygen-nitrogen integrated gas supply simulation training system; the oxygen cylinder simulation training system is connected to the oxygen supply terminal simulation training system; and the nitrogen cylinder simulation training system is connected to the nitrogen supply terminal simulation training system. Thus, through the control system, the user can control the system functions of each simulation training system at the front end.

[0017] Among them, by introducing an oxygen-nitrogen integrated gas simulation training system, users can simulate and train the generated oxygen and nitrogen to be filled into the oxygen storage tank of the oxygen cylinder simulation training system and the nitrogen storage tank of the nitrogen cylinder simulation training system, respectively, through the control system.

[0018] By introducing an oxygen cylinder chamber simulation training system, users can simulate the filling and storage of oxygen input from the oxygen-nitrogen integrated gas supply simulation training system into multiple oxygen storage cylinders through the control system.

[0019] By introducing a nitrogen cylinder simulation training system, users can simulate the filling and storage of nitrogen input from the oxygen-nitrogen integrated gas simulation training system into multiple nitrogen storage cylinders through the control system.

[0020] By introducing an oxygen supply terminal simulation training system, users can further simulate and train by controlling the control system to fill the corresponding gas receiving equipment with the input oxygen from the front end; similarly, by introducing a nitrogen supply terminal simulation training system, users can further simulate and train by controlling the control system to fill the corresponding gas receiving equipment with the input nitrogen from the front end. Therefore, through the above implementation methods, a multi-functional universal gas supply simulation training system can be realized, encompassing integrated oxygen and nitrogen gas supply simulation exercises, oxygen cylinder chamber simulation exercises, nitrogen cylinder chamber simulation exercises, oxygen supply terminal simulation exercises, and nitrogen supply terminal simulation exercises.

[0021] It should be noted that, in the embodiments of this application, the control system may be equipped with an industrial control computer and a server. The industrial control computer is connected to the server via Ethernet, and can upload the collected data to the server for remote display and analysis. It can also receive control commands from the server to control various simulation training systems. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior training data analysis and assessment.

[0022] The gas supply simulation training system of this application, through in-depth research and analysis of the commonality between gas production systems used in the shipbuilding and aerospace industries, and based on the simplified gas supply pipeline structure of the main functions, introduces and builds multiple core gas supply branch systems, including an oxygen-nitrogen integrated gas production simulation training system, an oxygen cylinder chamber simulation training system, a nitrogen cylinder chamber simulation training system, an oxygen supply terminal simulation training system, and a nitrogen supply terminal simulation training system. At the same time, a control system is designed using a combination of hardware and software, allowing users to independently control and operate the above-mentioned simulation training systems. This realizes a universal gas supply simulation training system with more comprehensive training content, which can effectively enrich the training functions of the gas supply simulation training system and greatly improve the training effect.

[0023] Figure 2 This is a schematic diagram of the framework structure of the oxygen-nitrogen integrated gas supply simulation training system provided in the embodiments of this application, as shown below. Figure 2 As shown, based on the above embodiments, as an optional embodiment, the oxygen-nitrogen integrated gas production simulation training system 2 includes an air compressor 21, a gas production simulation device 22, a nitrogen filling branch 23, and an oxygen filling branch 24; the nitrogen filling branch 23 includes a nitrogen storage tank 231, a first pressure sensor 232, and a first outlet valve 233 connected in sequence; the oxygen filling branch 24 includes an oxygen storage tank 241, a second pressure sensor 242, and a second outlet valve 243 connected in sequence. The inlet of the gas generation simulation device 22 is connected to the outlet of the air compressor 21. The first outlet of the gas generation simulation device 22 is connected to the nitrogen storage tank 231, and the second outlet is connected to the oxygen storage tank 241. The air compressor 21, the gas generation simulation device 22, the first air pressure sensor 232, the first air outlet valve 233, the second air pressure sensor 242, and the second air outlet valve 243 are all connected to the control system 1. Air compressor 21 is used to simulate the output of nitrogen and oxygen under the control of control system 1; The gas production simulation device 22 is used to simulate the pressurization and filling of nitrogen and oxygen into the corresponding gas storage tanks under the control of the control system 1; The control system 1 is also used to control the opening and closing states of the first air outlet valve 233 and the second air outlet valve 243, and to collect and display the pressure data of the first air pressure sensor 232 and the second air pressure sensor 242 for the user to view and assist in operation.

[0024] Specifically, it should be noted that in the actual production process, the oxygen-nitrogen integrated gas production system mainly consists of an air compressor, a gas pressure detection and sensing device, gas valves, an industrial control computer, and simulation software. The principle is to use air as raw material and adopt molecular sieve adsorption drying purification, deep freezing liquefaction, and low temperature distillation separation methods to produce oxygen and nitrogen to meet the needs of ships and ship equipment, as well as aircraft and airborne equipment.

[0025] In the embodiments of this application, the oxygen-nitrogen integrated gas production simulation training system simplifies the gas production equipment in terms of hardware, and uses compressed air output from an air compressor to directly simulate the output of oxygen and nitrogen. The subsequent process flow after the air compressor, such as gas purification, pressurization, and tank filling, is simulated by software simulation. Oxygen and nitrogen are temporarily stored and pressure buffered through independent gas cylinder groups to meet the requirements for a stable gas source.

[0026] More specifically, the control system in the simulation training system can be equipped with an industrial PC. The industrial PC can control and measure hardware such as air compressors, pressure gauges, and valves via RS485 or similar methods. For example, it can control the start and stop of the air compressor, acquire gas pressure data, and calculate gas flow rate based on valve opening. All data display and equipment operation can be completed by the user on the industrial PC's display screen.

[0027] Here, the simulation software can be developed using the QT5 platform, supporting cross-platform operation and running on Linux / Windows systems. Hardware-wise, it supports common hardware platforms such as x86, x64, and ARM. The gas source generates a fixed pressure of 0.7 MPa and a fixed flow rate of 8.4 Nm³ / h. To meet the simulation's technical parameter requirements, the pressure and flow rate of oxygen and nitrogen can be output linearly through software. By controlling the pressure and flow rate, the air compressor can simulate the output of oxygen and nitrogen. The specific conversion relationships are shown below: Oxygen pressure = gas source pressure * 4 / 7; Nitrogen pressure = gas source pressure * 6 / 7; Oxygen flow rate = gas source flow rate * 1.2; Nitrogen flow rate = gas source flow rate * 1.2.

[0028] Other values ​​such as purity, dew point, carbon dioxide content, and fixed particles can be configured and sent by the server, and then transmitted by the industrial control computer to the gas generation simulation equipment for simulation output.

[0029] In the embodiments of this application, the gas production simulation equipment can report the status information of the current gas production process, including the start and stop status of the air compressor, the status of the simulated output oxygen and nitrogen, gas pressure data, valve opening, and other status information. Simultaneously, it receives instructions from the industrial control computer and, through the simulation of the internal state and the coordination of the solenoid valves, simulates the operation states and processes such as gas purification, pressurization, and tank filling. The industrial control computer uses configuration-like software to cooperate with the gas production simulation equipment, providing a user interface for simulating a series of operation processes such as gas purification, pressurization, and tank filling.

[0030] Furthermore, the industrial control computer can control the opening and closing of the outlet valves on the nitrogen and oxygen cylinder supply lines to perform initial gas storage or further filling to the next-level system. Pressure data collected from the pressure sensors on the nitrogen and oxygen cylinder supply lines can be displayed visually on the industrial control computer's front-end monitor for user viewing and operational assistance.

[0031] Optionally, the gas pressure detection and sensing device can be composed of a combination of a traditional pointer-type pressure gauge and a pressure sensor. The pointer-type pressure gauge is embedded in the panel for intuitive display, while the pressure sensor can be connected to an industrial control computer to collect gas pressure data in real time and display it on the screen. The industrial control computer then transmits the data to the server.

[0032] It should be noted that, in the embodiments of this application, user control data and data generated during system operation, such as valve opening calculations, gas flow rate, and gas pressure data, can be collected and stored together using industrial control computer software to form a complete log file. This log file can be sent to a remote server for remote display and analysis. At this point, users with different roles, such as instructors, can use the transmitted log file to evaluate and score whether trainees can operate the oxygen-nitrogen integrated gas production system normally. This includes comprehensively scoring and assessing indicators such as the purity error of the gas produced, the gas injection volume, and whether the valve opening and gas pressure data collected by sensors meet standards.

[0033] Optionally, the oxygen-nitrogen integrated gas system simulation training system in this application embodiment can also be built according to the original structure of the existing oxygen-nitrogen integrated gas system without simplification, and can also realize the relevant simulation training functions.

[0034] The system in this application embodiment simplifies the gas production pipeline structure by analyzing the principle of oxygen-nitrogen integrated gas production and the linear relationship between the gas source and oxygen and nitrogen in terms of pressure and flow rate during the gas production process. This facilitates the reliable construction of an oxygen-nitrogen integrated gas production simulation training system, which can greatly improve the efficiency and effectiveness of oxygen-nitrogen integrated gas production simulation training while meeting the technical parameter requirements of the simulation.

[0035] Figure 3 This is a schematic diagram of the framework structure of the oxygen cylinder chamber simulation training system provided in the gas supply simulation training system of this application embodiment, as shown below. Figure 3As shown, based on the above embodiments, as an optional embodiment, the oxygen cylinder chamber simulation training system 3 includes a first inlet valve 31, a third outlet valve 32, a third pressure sensor 33, a fourth pressure sensor 34, and multiple first oxygen storage branches 35; each first oxygen storage branch 35 includes a first oxygen storage cylinder 351, a second inlet valve 352 connected to the inlet of the first oxygen storage cylinder 351, and a fourth outlet valve 353 connected to the outlet of the first oxygen storage cylinder 351. The first intake valve 31 is connected to the second intake valve 352 in each of the first oxygen storage branches 35 via the third pressure sensor 33, and the third outlet valve 32 is connected to the fourth outlet valve 353 in each of the first oxygen storage branches 35 via the fourth pressure sensor 34; the first intake valve 31, the third outlet valve 32, the second intake valve 352, the fourth outlet valve 353, the third pressure sensor 33 and the fourth pressure sensor 34 are all connected to the control system 1; The control system 1 is used to control the opening and closing states of the first inlet valve 31, the third outlet valve 32, each of the second inlet valves 352 and each of the fourth outlet valves 353 respectively, so as to simulate filling oxygen into each of the first oxygen storage cylinders 351.

[0036] Specifically, in actual production, the oxygen cylinder system mainly consists of gas cylinders, gas pressure detection sensors, gas valves, an industrial control computer, and simulation software. Its working principle typically involves an integrated oxygen-nitrogen gasification system pressurizing the oxygen storage cylinder group to 15MPa. During the oxygen supply module's operation, oxygen at 0.5MPa (adjustable) is supplied after pressure reduction via an adjustable oxygen pressure reducing valve. In case of overpressure, the oxygen safety valve releases the pressure through the main exhaust pipe. During malfunctions or maintenance, the oxygen cylinder valve can be closed first, and then the pressure is released through the cylinder exhaust shut-off valve via the main exhaust pipe. Each oxygen storage cylinder group has an independent set of pressure measurement, filling, safety venting, active venting, and main gas supply functions, ensuring that during maintenance or malfunctions, one oxygen cylinder group is always operational, facilitating gas replacement and venting operations while conserving gas resources. The system also includes an oxygen pressure transmitter, an oxygen pneumatic ball valve, and a solenoid valve, facilitating remote system monitoring and allowing for oxygen cut-off control of the pneumatic ball valve via the solenoid valve in emergency situations.

[0037] In the embodiments of this application, the oxygen cylinder chamber simulation training system simplifies the cylinder pipelines and their number in the hardware of the actual oxygen cylinder chamber system. It mainly includes a first inlet valve, a third outlet valve, a third pressure sensor, a fourth pressure sensor, and multiple first oxygen storage branches. Each first oxygen storage branch includes an oxygen storage cylinder, i.e., a first oxygen storage cylinder; an inlet valve connected to the inlet of the oxygen storage cylinder, i.e., a second inlet valve; and a supply valve connected to the outlet of the oxygen storage cylinder, i.e., a fourth outlet valve.

[0038] Similarly, in the control process of the oxygen cylinder chamber simulation training system, the control system can be equipped with an industrial computer. The industrial computer can realize the measurement and control of hardware facilities such as pressure gauges and various valves through RS485 and other means. For example, it can acquire gas pressure data and calculate gas flow rate based on valve opening. All monitoring data can be displayed on the industrial computer screen. At the same time, the industrial computer uses configuration-like software to control various valves to simulate a series of operations such as opening and closing, filling, storage, and maintenance of gas cylinders.

[0039] It should be noted that the gas pressure detection sensor and the gas pressure detection method in the oxygen-nitrogen integrated gas simulation training system are the same.

[0040] In this system, the opening and closing of individual oxygen storage cylinders are directly controlled by individual valves, and the valve status can be fed back to the industrial control computer. By monitoring the opening and closing status of the first inlet valve, the third outlet valve, the corresponding second inlet valve, and the corresponding fourth outlet valve, the pressure rise and fall of the gas in each storage cylinder is simulated to simulate the oxygen filling and storage process. Optionally, maintenance and other operations can also be simulated by software on the industrial control computer.

[0041] Here, the first intake valve supplies a fixed 0.7MPa compressed air from the upstream air source, and the gas pressure inside the cylinder is also 0.7MPa. The supply valve can adjust the output gas pressure according to its opening degree. To meet the technical parameter requirements of the simulation, the oxygen pressure is output through linear conversion in the software. The conversion relationship is as follows: Air supply pressure = Inlet air source pressure * 5 * Air supply valve opening percentage.

[0042] It should also be noted that the industrial control computer connects to the server via Ethernet, allowing the collected data to be uploaded for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0043] Optionally, the oxygen cylinder chamber simulation training system in this embodiment can also be built according to the original structure of the existing oxygen cylinder chamber system without simplification, and can also realize the relevant simulation training functions.

[0044] The system in this application embodiment simplifies the gas pipeline structure by analyzing the gas storage principle of the oxygen cylinder and the relationship between the gas supply pressure and the opening of the gas supply valve during the process. It facilitates the reliable construction of an oxygen cylinder simulation training system and can greatly improve the efficiency and effectiveness of oxygen cylinder simulation training while meeting the requirements of simulation technical parameters.

[0045] Figure 4This is a schematic diagram of the framework structure of the nitrogen cylinder chamber simulation training system provided in the gas supply simulation training system of this application embodiment, as shown below. Figure 4 As shown, based on the above embodiments, as an optional embodiment, the nitrogen cylinder chamber simulation training system 4 includes a third inlet valve 41, a fifth outlet valve 42, a fourth pressure sensor 43, a fifth pressure sensor 44, and multiple nitrogen storage branches 45; each nitrogen storage branch 45 includes a nitrogen storage cylinder 451, a fourth inlet valve 452 connected to the inlet of the nitrogen storage cylinder 451, and a sixth outlet valve 453 connected to the outlet of the nitrogen storage cylinder 451. The third intake valve 41 is connected to the fourth intake valve 452 in each nitrogen storage branch 45 through the fourth pressure sensor 43; the fifth outlet valve 42 is connected to the sixth outlet valve 453 in each nitrogen storage branch 45 through the fifth pressure sensor 44; the third intake valve 41, the fifth outlet valve 42, the fourth intake valve 452, the sixth outlet valve 453, the fourth pressure sensor 43 and the fifth pressure sensor 44 are all connected to the control system 1; The control system 1 is used to control the opening and closing states of the third inlet valve 41, the fifth outlet valve 42, each of the fourth inlet valves 452 and each of the sixth outlet valves 453 respectively, so as to simulate filling nitrogen into each nitrogen storage cylinder 451, and to collect pressure data from the fourth pressure sensor 43 and the fifth pressure sensor 44 for the user to view and assist in operation.

[0046] Specifically, in actual production, the nitrogen cylinder system mainly consists of gas cylinders, gas pressure detection sensors, gas valves, industrial control computers, and simulation software. Similar to the working principle of the oxygen cylinder system, the main working principle of the nitrogen cylinder system is that after the oxygen-nitrogen integrated gas supply system pressurizes the nitrogen storage cylinder group to 15MPa, the nitrogen supply module provides 0.5MPa nitrogen (adjustable) obtained by reducing pressure through the nitrogen pressure reducing valve (adjustable) during operation.

[0047] In the embodiments of this application, the nitrogen cylinder chamber simulation training system simplifies the cylinder pipelines and their number in the hardware of the actual nitrogen cylinder chamber system. It mainly includes a third inlet valve, a fifth outlet valve, a fourth pressure sensor, a fifth pressure sensor, and multiple nitrogen storage branches. Each nitrogen storage branch includes a nitrogen storage cylinder, an inlet valve connected to the inlet of the nitrogen storage cylinder (i.e., the fourth inlet valve), and a supply valve connected to the outlet of the nitrogen storage cylinder (i.e., the sixth outlet valve).

[0048] Similarly, in the control process of the nitrogen cylinder chamber simulation training system, the control system can be equipped with an industrial computer. The industrial computer can realize the measurement and control of hardware facilities such as pressure gauges and valves via RS485 and other means, such as acquiring gas pressure data and calculating gas flow rate based on valve opening. All data can be displayed on the industrial computer screen, and the industrial computer uses configuration-like software to simulate a series of operations such as cylinder opening and closing, filling, storage, and maintenance.

[0049] In this system, the opening and closing of individual nitrogen storage cylinders are directly controlled by individual valves, and the valve status can be fed back to the industrial control computer. By monitoring the opening and closing status of the third inlet valve, the fifth outlet valve, the corresponding fourth inlet valve, and the corresponding sixth outlet valve, the pressure rise and fall of the gas in each storage cylinder are simulated to simulate the nitrogen filling and storage process. Optionally, maintenance and other operations can also be simulated by software on the industrial control computer.

[0050] Here, the third air inlet valve supplies a fixed 0.7MPa compressed air from the upstream air source, and the gas pressure inside the cylinder is also 0.7MPa. The air supply valve can adjust the output gas pressure according to its opening degree. To meet the technical parameter requirements of the simulation, the nitrogen pressure is output through linear conversion in the software. The conversion relationship is as follows: Air supply pressure = Inlet air source pressure * 5 * Air supply valve opening percentage.

[0051] The gas pressure detection method is the same as that in the oxygen-nitrogen integrated gas simulation training system. The pressure gauge displays a pressure from 0 MPa to 35 MPa (continuously adjustable).

[0052] Similarly, the industrial control computer connects to the server via Ethernet, allowing it to upload the collected simulation training system data for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0053] Optionally, the nitrogen cylinder chamber simulation training system in this application embodiment can also be built according to the original structure of the existing nitrogen cylinder chamber system without simplification, and can also realize the relevant simulation training functions.

[0054] The system in this application embodiment simplifies the gas pipeline structure by analyzing the gas storage principle of nitrogen cylinders and the relationship between gas supply pressure and gas supply valve opening during the process. It facilitates the reliable construction of a nitrogen cylinder simulation training system and can greatly improve the efficiency and effectiveness of nitrogen cylinder simulation training while meeting the requirements of simulation technical parameters.

[0055] Figure 5 This is a schematic diagram of the framework structure of the oxygen supply terminal simulation training system provided in the gas supply simulation training system of this application embodiment, as shown below. Figure 5 As shown, based on the above embodiments, as an optional embodiment, the oxygen supply terminal simulation training system 5 includes a fifth inlet valve 51, a sixth pressure sensor 52, a first pressure reducing valve 53, a seventh pressure sensor 54, and a seventh outlet valve 55 connected in sequence. The fifth inlet valve 51 is connected to the third outlet valve 32, and the seventh outlet valve 55 is used to connect to the receiving equipment; the fifth inlet valve 51, the sixth pressure sensor 52, the first pressure reducing valve 53, the seventh pressure sensor 54 and the seventh outlet valve 55 are all connected to the control system 1. The control system 1 is used to control the state of the fifth inlet valve 51, the seventh outlet valve 55, and the first pressure reducing valve 53 respectively, so as to simulate filling the oxygen stored in each first oxygen storage cylinder 351 into the receiving equipment.

[0056] Specifically, in the embodiments of this application, the oxygen supply terminal simulation training system mainly consists of a pressure reducing valve, a gas pressure detection sensor, and gas valves. The oxygen supply terminal equipment uses the gas cylinder source from the upper-level system as its main component. After filtration and pressure regulation, the gas is connected to the matching hoses and connectors and filled into the receiving equipment. Overpressure protection safety valves are installed in the pipeline system for 35MPa input and 27.5MPa output to improve safety during use.

[0057] In the embodiments of this application, the oxygen supply terminal simulation training system simplifies the original system by retaining only the pressure reducing valve in the hardware and simulating pressure reduction operations through software. The pressure reducing valve reduces the gas pressure, which is then output through a hose. The reduced gas pressure is fed back to the industrial control computer for display. The hose can be configured with different lengths, with a maximum length of 30 meters, enabling direct oxygen supply to receiving equipment such as ship equipment, aircraft, and aviation oxygen supply vehicles within a 30-meter range.

[0058] More specifically, in the embodiments of this application, the oxygen supply terminal simulation training system mainly includes a fifth inlet valve, a sixth pressure sensor, a first pressure reducing valve, a seventh pressure sensor, and a supply valve (i.e., a seventh outlet valve) connected in sequence. The first pressure reducing valve supports pressure reduction for oxygen, nitrogen, and compressed air, with an inlet pressure less than 15 MPa, an outlet pressure adjustable from 0 to 1.6 MPa, and a gas flow rate greater than 100 Nm³. 3 / H.

[0059] The fifth intake valve supplies a fixed 0.7MPa compressed air from the upstream air source. The first pressure reducing valve adjusts the output gas pressure based on its opening degree. To meet the simulation's technical parameter requirements, and based on practical experience, the output oxygen pressure is determined through linear calculation in the software. The conversion relationship is as follows: Input pressure = Intake air source pressure * 50; Output pressure = Inlet air source pressure * 5 * Pressure reducing valve opening percentage * 25 / 35; Or, output pressure = input pressure; Similarly, in the control process of the oxygen supply terminal simulation training system, the control system can be equipped with an industrial computer. The industrial computer can realize the measurement and control of hardware facilities such as pressure gauges and valves through RS485 and other means, such as acquiring gas pressure data and calculating gas flow rate based on valve opening.

The control system 1 is used to control the state of the sixth inlet valve 61, the eighth outlet valve 65 and the second pressure reducing valve 63 respectively, so as to simulate filling the nitrogen stored in the nitrogen storage cylinder 451 into the gas receiving device.

[0064] Specifically, in the embodiments of this application, similar to the oxygen supply terminal simulation training system, the nitrogen supply terminal simulation training system mainly consists of a pressure reducing valve, a gas pressure detection sensor, and gas valves.

[0067] Similarly, the sixth intake valve supplies a fixed 0.7MPa compressed air from the upstream air source, while the second pressure reducing valve adjusts the output gas pressure based on its opening. To meet the simulation's technical parameter requirements, and based on practical experience, the nitrogen pressure is output via linear calculation in the software. The conversion relationship is as follows: Input pressure = Intake air source pressure * 50; Output pressure = Inlet air source pressure * 5 * Pressure reducing valve opening percentage * 27.5 / 35; Or, output pressure = input pressure; Similarly, in the control process of the nitrogen supply terminal simulation training system, the control system can be equipped with an industrial computer. The industrial computer can control hardware facilities such as pressure gauges and valves via RS485 or other methods, for example, acquiring gas pressure data and calculating gas flow rate based on valve opening.

[0071] Specifically, in the embodiments of this application, the aviation oxygen supply equipment simulation training system mainly consists of a pressure reducing valve, a gas pressure detection sensor, and a gas valve. The aviation oxygen supply vehicle, as a sub-equipment of the aviation gas supply system, can be moved and used in narrow spaces over short distances. The use of matching hose connectors can ensure the oxygen supply needs of the aircraft. The system hardware includes a simulated aviation oxygen supply vehicle and a gas supply hose, which can be used to perform high-pressure gas pressure reduction, oxygen supply to the aircraft, and other related operations.

[0072] In the embodiments of this application, compared to the oxygen supply terminal simulation training system, the aviation oxygen supply equipment simulation training system adds multiple sets of oxygen storage cylinders in terms of hardware, such as... Figure 7 As shown, five sets of 15L oxygen cylinders are added, and the output gas from the oxygen cylinders is depressurized via a third pressure-reducing valve. The depressurized gas can then be used to supply oxygen to the aircraft. The third pressure-reducing valve also supports depressurization of oxygen, nitrogen, and compressed air, with an inlet pressure less than 15MPa, an adjustable outlet pressure of 0~1.6MPa, and a gas flow rate greater than 100Nm³. 3 / H.

[0073] Similarly, the seventh intake valve supplies a fixed 0.7MPa compressed air from the upstream air source, while the third pressure reducing valve adjusts the output gas pressure based on its opening. To meet the simulation's technical parameter requirements, and based on practical experience, the output oxygen pressure is determined through linear calculation in the software. The conversion relationship is as follows: Input pressure = Intake air source pressure * 50; Output pressure = Inlet air source pressure * 5 * Pressure reducing valve opening percentage * 25 / 35; Or, output pressure = input pressure; Similarly, in the control process of an aviation oxygen supply equipment simulation training system, the control system can also be equipped with an industrial PC. The industrial PC can use RS485 or similar methods to measure and control hardware facilities such as pressure gauges and valves, for example, acquiring gas pressure data and calculating gas flow based on valve opening. All data can be displayed on the industrial PC's screen. The industrial PC connects to the server via Ethernet, allowing it to upload the collected simulation training system data for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0074] Optionally, the aviation oxygen supply equipment simulation training system in this application embodiment can also be built according to the original structure of the existing aviation oxygen supply equipment gas supply system without simplification, and can also realize the relevant simulation training functions.

[0075] The system in this application embodiment, by analyzing the principle of the air supply system of aviation oxygen supply equipment and the relationship between the input and output pressure and the pressure of the air source and the opening of the pressure reducing valve, simplifies the gas pipeline structure and facilitates the reliable construction of an aviation oxygen supply equipment simulation training system. It can greatly improve the efficiency and effect of aviation oxygen supply equipment simulation training while meeting the requirements of simulation technical parameters.

[0076] Figure 8 This is a schematic diagram of the framework structure of the compressed air supply terminal simulation training system provided in the air supply simulation training system of this application embodiment, as shown below. Figure 8As shown, based on the above embodiments, as an optional embodiment, the air supply simulation training system further includes a compressed air supply terminal simulation training system 8; the compressed air supply terminal simulation training system 8 includes a ninth inlet valve 81, a twelfth pressure sensor 82, a fourth pressure reducing valve 83, a thirteenth pressure sensor 84 and an eleventh outlet valve 85 connected in sequence. The ninth intake valve 81 is connected to the outlet of the air compressor 21, and the eleventh exhaust valve 85 is used to connect to the receiving equipment. The ninth intake valve 81, the twelfth pressure sensor 82, the fourth pressure reducing valve 83, the thirteenth pressure sensor 84, and the eleventh exhaust valve 85 are all connected to the control system 1 and are used to simulate the supply operation of compressed air output by the air compressor 21 under the control of the control system 1.

[0077] Specifically, in the embodiments of this application, the compressed air supply terminal simulation training system mainly consists of a pressure reducing valve, a gas pressure detection sensor, and a gas valve. In practical applications, the compressed air supply terminal simulation training system uses a pipeline formed by a supply hose, with one end connected to an air compressor and the other end connected to a spray gun via the supply hose. It can perform high-pressure gas pressure reduction, blowing on the ground, panels or corners of ships and the fuselage of aircraft, as well as related training such as inflating aircraft tires.

[0078] Compared to oxygen supply terminals, compressed air supply terminals draw their air directly from air compressors. They are otherwise similar to oxygen supply terminals, including reducing gas pressure via pressure reducing valves.

[0079] More specifically, in the embodiments of this application, the compressed air supply terminal simulation training system includes a ninth inlet valve, a twelfth pressure sensor, a fourth pressure reducing valve, a thirteenth pressure sensor, and an eleventh outlet valve connected in sequence. The fourth pressure reducing valve also supports pressure reduction for nitrogen, compressed air, etc., with an inlet pressure less than 15 MPa, an outlet pressure adjustable from 0 to 1.6 MPa, and a gas flow rate greater than 100 Nm³. 3 / H.

[0080] In the embodiments of this application, the ninth intake valve provides compressed air at a fixed pressure of 0.7 MPa generated by the compressor, and the fourth pressure reducing valve can adjust the output gas pressure according to its opening degree. To meet the technical parameter requirements of the simulation, and based on practical experience, the output oxygen pressure is determined through linear conversion in software. The conversion relationship is as follows: Input pressure = Intake air source pressure * 19.6 / 0.7; Output pressure = Intake air source pressure * 5 / 7; Terminal pressure = Intake air source pressure * 5 / 7; Other values, such as oil content, dew point, and dust particle size, are configured by the server and then output by the industrial computer.

[0081] Similarly, in the control process of the compressed air supply terminal simulation training system, the control system can be equipped with an industrial computer. The industrial computer can control and measure hardware facilities such as pressure gauges and valves via RS485 or other methods, for example, acquiring gas pressure data and calculating gas flow rate based on valve opening. All data can be displayed on the industrial computer's screen. Furthermore, the industrial computer can connect to a server via Ethernet, allowing the collected simulation training system data to be uploaded for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0082] It should be noted that the gas pressure detection sensor can also be the same as the gas pressure detection method in the oxygen-nitrogen integrated gas simulation training system.

[0083] The system in this application embodiment simplifies the gas pipeline structure by analyzing the principle of the compressed air supply terminal system and the relationship between the input and output pressure and the intake air source pressure during the process. It facilitates the reliable construction of a compressed air supply terminal simulation training system, which can greatly improve the efficiency and effectiveness of compressed air supply terminal simulation training while meeting the requirements of simulation technical parameters.

[0084] Figure 9 This is a schematic diagram of the framework structure of the aviation air conditioning equipment simulation training system provided in the air supply simulation training system of this application embodiment, as shown below. Figure 9 As shown, based on the above embodiments, as an optional embodiment, the gas supply simulation training system further includes an aviation air conditioning equipment simulation training system; the aviation air conditioning equipment simulation training system is connected to the control system; The aviation air conditioning equipment simulation training system is built based on air conditioning equipment, valves, and air pressure sensors. It is used to simulate and train users to perform functional operations on aviation air conditioning equipment under the control of the control system.

[0085] Specifically, in the embodiments of this application, the aviation air conditioning equipment simulation training system, as an independent training system, can consist of air conditioning simulation equipment, gas pressure detection sensors, and gas valves. The control system side can specifically consist of simulated aviation air conditioning facilities, an industrial control computer, and simulation software. The simulated aviation air conditioning facilities are divided into two parts: a simulated air conditioning control box and a simulated air conditioning monitoring console. The simulated air conditioning control box is used for air conditioning cooling, heating, dehumidification, and other related operations, while the simulated air conditioning monitoring console is used for remote control of the air conditioning facilities and other related operations.

[0086] Optionally, the aviation air conditioning facility simulation training system can also be extended to the air conditioning cooling, heating and dehumidification operations of ship systems, and the simulated air conditioning monitoring station set up in the ship equipment can also be used to perform remote control of air conditioning facilities and other related operations.

[0087] During the control process of the aviation air conditioning facility simulation training system, the industrial control computer on the control system side can monitor the air conditioning simulation equipment via RS485 or other means, such as acquiring environmental measurement data and controlling the operation of the air conditioning. All data can be displayed on the industrial control computer's screen.

[0088] The industrial control computer connects to the server via Ethernet, allowing it to upload collected data for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0089] It should be noted that the air conditioning simulation equipment can select a real air conditioning unit, connect to the air conditioning control box via a remote control line, and directly control the air conditioning unit; at the same time, the monitoring data is transmitted to the industrial control computer, which simulates a monitoring console, and the air conditioning unit can be remotely controlled from the monitoring console.

[0090] Here, the gas pressure detection sensor can also be the same as the gas pressure detection method in the aforementioned oxygen-nitrogen integrated gas simulation training system.

[0091] In the embodiments of this application, the simulation software is developed using the QT5 platform, supports cross-platform operation, and can run on Linux / Windows systems. Hardware-wise, it supports common hardware platforms such as x86, x64, and ARM. Air conditioning-related values ​​can be configured by the server and then output by the industrial control computer.

[0092] In one specific embodiment of this application, the common performance parameter standard values ​​implemented by the aviation air conditioning facility simulation training system are as follows: Inlet air temperature: 35℃, inlet air relative humidity: 97%, outlet air temperature: 14℃, outlet air humidity: moisture content ≤8g / kg; Inlet air temperature: -18℃, inlet air relative humidity: 80%, outlet air temperature: 50℃~60℃, adjustable; outlet air humidity ≤40%.

[0093] like Figure 10 As shown in the embodiments of this application, a gas receiving equipment simulation training system can also be provided, which can specifically consist of a gas storage cylinder, a pressure relief valve, multiple inlet valves, multiple outlet valves and a gas pressure detection sensor. It is connected to the control system and can be used to simulate the acceptance of various gases provided by various gas supply equipment in ship and aviation operations under the control of the control system.

[0094] The receiving device receives the gas output from the preceding test stage, which can be stored in three 15L gas cylinders before being discharged through a pressure relief valve. The receiving device is not limited to any particular gas type; oxygen, nitrogen, compressed air, etc., can all be connected.

[0095] Similarly, in the control process of the gas receiving equipment simulation training system, the control system can be equipped with an industrial PC. The industrial PC can control hardware facilities such as pressure gauges and valves via RS485 or similar methods, for example, acquiring gas pressure data and calculating gas flow rate based on valve opening. All data can be displayed on the industrial PC's screen. Furthermore, the industrial PC can connect to a server via Ethernet, allowing the collected simulation training system data to be uploaded for remote display and analysis. All simulation operations and data can be stored locally as logs or transmitted to the server for user behavior analysis.

[0096] Most existing gas supply simulation training systems do not implement a client-server (C / S) network platform architecture, meaning they lack dedicated training and teaching platforms for one-to-many, many-to-one, or many-to-many interactions. As a result, organizations cannot effectively understand the actual learning situation of trainees after gas supply simulation training, collect and analyze data on the learning process and results, develop new teaching plans, or improve the shortcomings of the simulation training system. Ultimately, this leads to low teaching effectiveness and a waste of time and teaching resources.

[0097] Therefore, in view of the problems existing in the above-mentioned traditional gas supply simulation training system, this application also provides a gas supply simulation training system as described below.

[0098] Figure 11 This is a second schematic diagram of the gas supply simulation training system provided in the embodiments of this application, as shown below. Figure 11 As shown, based on the above embodiments, as an optional embodiment, the control system 1 includes a central server system 11, and a first industrial control computer 12 and a second industrial control computer 13 respectively connected to the central server system 11; each simulation training system is connected to the central server system 11. The central server system 11 is used to respond to user input commands from the second industrial control computer 13, control the corresponding system functions of each simulation training system, and acquire monitoring data during the operation of each simulation training system. The first industrial control computer 12 is used to evaluate the operation of the second industrial control computer 13 based on monitoring data.

[0099] Specifically, in the embodiments of this application, the control system includes a central server system, a first industrial control computer, and a second industrial control computer. The first industrial control computer can serve as the instructor's terminal for instructors, and the second industrial control computer can serve as the student's terminal for students. Multiple second industrial control computers can be configured for multiple students to form a client / server (C / S) software architecture. The student terminals can be deployed as needed; given the current server performance and network equipment configuration, it supports the deployment of at least 100 student terminals. The central server system may include a central server and a network switch for connecting to the gas supply simulation training system.

[0100] In the embodiments of this application, a C / S architecture is adopted, where all instructor terminals, student terminals, etc., run different types of client software and communicate with the backend service on the server via Ethernet connection. The simulation practice system software is mainly developed around three modules: user management, subject management, and learning and assessment. Its main functions are as follows: 1) User management mainly implements the system's management functions such as adding, deleting, modifying, and querying data; 2) Subject management mainly enables instructors to add, modify, set, and maintain basic information and modes related to teaching and practice subjects; and to set and manage various data and requirements associated with subjects. 3) Enable interactive teaching management and assessment functions for instructors and students.

[0101] In this embodiment, by introducing a C / S software architecture, training, teaching, and assessment functions can be provided for eight subsystems, including oxygen-nitrogen integrated gas supply simulation training, oxygen cylinder chamber simulation training, nitrogen cylinder chamber simulation training, oxygen supply terminal simulation training, nitrogen supply terminal simulation training, aviation oxygen filling equipment simulation training, compressed air supply terminal simulation training, and aviation air conditioning equipment simulation training, all required by the gas supply simulation training system. Each subsystem is implemented using a combination of hardware and software, interconnected via Ethernet, and communicates with the central server. The instructor and student terminals are built on the central server; the instructor terminal provides functions such as teaching resource management and teaching task assignment, while students can learn and practice through the student terminal.

[0102] Optionally, such as Figure 11As shown in the embodiments of this application, an independent air supply simulation training system can also be provided, in which the outlet of the air compressor is connected to the oxygen cylinder chamber simulation training system, the nitrogen cylinder chamber simulation training system, the oxygen supply terminal simulation training system, the nitrogen supply terminal simulation training system, the oxygen supply terminal simulation training system, and the compressed air supply terminal simulation training system, respectively. The compressed air output by the air compressor is used to directly simulate the output of oxygen and nitrogen, providing an air source for each of the above simulation training systems and realizing the independent training function of each of the above simulation training systems.

[0103] In one specific embodiment of this application, the operational steps of the gas supply simulation training system include: Step 1: Control the compressed air generated by the air compressor to provide an air source for the subsequent simulation training systems through pipelines. If there is no fault, proceed to Step 2.

[0104] Step two: The oxygen-nitrogen integrated gas production simulation training system also includes an air compressor. This compressor is controlled to simulate the gas production process. The gas produced during this process is piped to the lower-level oxygen cylinder simulation training system and nitrogen cylinder simulation training system. Alternatively, the simulation process of the oxygen cylinder simulation training system and nitrogen cylinder simulation training system can switch to a mode that departs from the oxygen-nitrogen integrated gas production, with the air compressor from step one directly providing the gas source for simulation training. Either of these two states can be selected before proceeding to step three. Additionally, the compressed air produced by the air compressor can be piped to a separate compressed air supply terminal simulation training system and proceed to step three. The aviation oxygen supply vehicle simulation training system and the aviation air conditioning equipment simulation training system can also proceed to step three through steps one and two.

[0105] Step 3: The oxygen and nitrogen supply terminal equipment simulation training system uses the gas cylinders from the upper-level system as the main source. After filtration and pressure regulation, the gas is supplied to the receiving equipment via matching hoses and connectors, targeting an input of 35MPa and an output of 27.5MPa. The aviation oxygen supply vehicle, as a sub-equipment of the aviation gas supply system, uses matching hose connectors to ensure the aircraft's oxygen supply needs. Its system hardware includes a simulated aviation oxygen supply vehicle and supply hoses, used for high-pressure gas decompression, aircraft oxygen supply, and other related operations. The compressed air supply terminal simulation training system connects to an air compressor at one end of a pipeline and to a spray gun at the other end via a supply hose. It can perform high-pressure gas decompression, cleaning of ships and aircraft, and tire inflation for practice. Additionally, the aviation air conditioning equipment simulation training system simulates air conditioning control, used for cooling, heating, and dehumidification operations. If normal, proceed to Step 4.

[0106] Step four involves the oxygen and nitrogen supply terminal equipment simulation training system, the aviation oxygen supply vehicle simulation training system, the aviation air conditioning equipment simulation training system, and the compressed air supply terminal simulation training system supplying oxygen, nitrogen, and compressed air to ship and aviation gas receiving equipment via corresponding connections. After the simulation is complete, proceed to step five.

[0107] Step 5: All gas supply simulation system components from Steps 1 to 4 above can be controlled by the industrial control computer in the control system. The gas pressure data is collected in real time by sensors and displayed on the screen. The gas flow rate is calculated by the valve opening. The collected monitoring data is transmitted to the server via Ethernet in the form of a work log for analysis, control, and simulation teaching. Proceed to Step 6.

[0108] Step Six: The instructor manages, teaches, and assesses the students using the materials provided by the simulation training system. The students learn from the assessment results, identify their weaknesses, and return to Steps One through Four for simulation training. The teaching and learning progress can be shared by the server via Ethernet, and AI technology is used to automatically process the teaching and scoring mechanisms in an engaging manner.

[0109] The system provided in this application adopts a C / S software architecture to realize a relatively complete and highly professional gas supply simulation training system with advantages such as network platform training, data collection and analysis. The operation of this system can bring good training results to personnel in the shipbuilding and aviation industries, and help personnel become more familiar with the gas supply system, thereby reducing the economic costs of training, maintenance and fault testing.
