Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of torpedo launching tube escape training, in particular to a torpedo launching tube escape training method and system. BACKGROUND

[0002] In the modern submarine combat and maintenance training system, the submarine crew performs emergency escape training from the torpedo launching tube, which is a crucial task aimed at simulating how the submarine crew quickly and safely escapes from the enclosed torpedo launching tube in real emergency situations. However, the current training method faces two key challenges, which seriously affect the effectiveness of the training and the psychological adaptability of the submarine crew.

[0003] I. Psychological fear in a fully enclosed environment: In traditional simulation training, the torpedo launching tube is made of metal material, and its structure design fully meets the actual combat standard, but it brings additional difficulty to the training in terms of airtightness. Once the front and rear covers are closed, the internal space is immediately plunged into absolute darkness, lacking natural light or artificial lighting. This extreme dark environment is not only a visual test for the submarine crew, especially for novice submarine crew, but also a great psychological challenge. When the submarine crew operates in a completely dark environment, they are prone to panic, resulting in judgment errors, slow operation, and even missing the best escape opportunity. According to statistics, there are not a few cases of operation errors caused by psychological fear, which seriously affects the overall success rate of simulation training.

[0004] II. Insufficient control accuracy of water injection regulating valve: On the other hand, the existing training facilities have obvious technical limitations in controlling the water injection regulating valve during the simulation of rapid ascent escape. Due to the lack of high-precision automatic control system, the adjustment of water injection rate often relies on manual experience, making it difficult to achieve rapid and accurate pressure balance and adjustment, which directly limits the simulation degree of the emergency ascent scene in simulation training. The inability to accurately simulate water level rising at different rates means that the submarine crew cannot effectively master the rapid decompression skills, reducing the practical application value of the training. SUMMARY

[0005] This section aims to outline some aspects of the embodiments of the present application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of the specification to avoid obscuring the purpose of this section, abstract and title, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0006] In view of the above or the existing problems in the prior art that the current torpedo launching tube escape training has obvious shortcomings in terms of full-enclosed dark environment adaptability training and precise water injection regulation, the present application is proposed.

[0007] To solve the above technical problems, the present application provides the following technical solutions: a torpedo tube escape training method, comprising the following steps:

[0008] The simulator is prepared and the personnel are positioned: the torpedo tube simulator is configured with a controllable sealing end cover for maintaining the internal standard pressure condition, and after the diver is equipped, he enters through the rear end and is closed for preparation of the training;

[0009] The escape training: an integrated intelligent water injection adjustment system is used to dynamically control the water injection rate to balance the internal and external pressures of the simulator and automatically open the front end cover; the escape process simulation includes two pressure adjustment modes: a) fast decompression mode, suitable for simulating emergency escape situations; b) controlled decompression mode, suitable for gradual decompression training; after the front cover is opened, the diver escapes into the connected simulated water area and selects an appropriate speed to float according to the training requirements.

[0010] As a preferred embodiment of the torpedo tube escape training method of the present application, the escape training includes a simulated fast ascent escape training project corresponding to a) fast decompression mode, which includes the following steps:

[0012] Pressure balance monitoring and adjustment: the gas pressure in the torpedo tube is continuously monitored and the water injection rate is automatically adjusted until it reaches a balanced state with the external pool water level pressure, ensuring safety and simulation during the training process;

[0013] Cover release: once the pressure is balanced, the mechanism is automatically or manually started to open the front end cover of the torpedo tube, providing a channel for the diver to enter the large pool;

[0017] Primary decompression stay: after pressure balance, the diver safely enters the large pool from the torpedo launching tube and immediately sinks to a depth of 4 meters underwater, uses the suspended ladder preset at this position to stabilize the body, and performs a 5-minute primary decompression stay to adapt to the underwater pressure change;

[0018] Secondary decompression stay: after the primary decompression stay is completed, the diver floats to a depth of 2 meters underwater according to the standard procedure, and again relies on the suspended ladder to perform a 2-minute secondary decompression stay to further ensure that the body pressure is gradually adjusted to adapt to the shallow water environment;

[0019] Safe ascent: after completing all scheduled decompression stays, the diver follows the decompression principle and gently ascends to the water surface, marking the successful completion of this decompression escape simulation training.

[0020] As a preferred scheme of the torpedo launching tube escape simulation training method of the present application, wherein: environmental adaptability training progression: gradually adjust the environment according to the training situation, initially in a transparent torpedo launching tube simulation device, in the middle stage in a completely closed and light-free environment, and in the later stage using virtual reality (VR) technology to superimpose extreme environment simulation for training.

[0025] A pressure monitoring module for real-time monitoring of the pressure difference between the inside and outside of the torpedo launching tube, feeding back data to the intelligent water injection adjustment module to achieve accurate control;

[0026] A virtual reality (VR) environment simulation module is used to provide diversified training scenarios from transparent environment, fully closed and lightless environment to extreme environment.

[0027] A training management system is integrated with a computer application program, which can control the above components, set training mode, record training data, and guide divers to operate.

[0028] As a preferred scheme of the torpedo tube escape training system, the intelligent water injection adjustment module comprises a water injection control valve, which can dynamically adjust the opening degree according to the instruction of the computer application program to realize linear or exponential increase of pressure control.

[0029] A pressure sensing interface is integrated with the pressure monitoring module to ensure quick response and adjustment of the water injection rate to achieve the predetermined pressure balance time or the required gas pressure change rate of simulated rapid ascent.

[0030] The pressure monitoring module comprises a multi-point pressure sensor arranged at key positions inside and outside the torpedo tube for all-around and real-time pressure monitoring.

[0031] A data processing unit integrates the pressure sensor data, calculates the internal and external pressure difference, and transmits the real-time data to the intelligent water injection adjustment system and the training management system.

[0032] As a preferred scheme of the torpedo tube escape training system, a hollow interlayer is arranged inside the torpedo tube, and a black dye circulating module is connected to the interlayer, which comprises a dye storage tank, a pump body, and a switching valve core arranged in the water injection control valve.

[0033] As a preferred scheme of the torpedo tube escape training system, the valve body of the water injection control valve penetrates the interlayer, the switching valve core comprises a pair of through holes in the valve body communicating with the interlayer, a branch pipe is arranged at the lower end of the valve body, the branch pipe is provided with a communication hole in the valve body, a double rhombus frame is arranged in the valve body, the two ends of the double rhombus frame are provided with an upper plug and a lower plug for plugging the upper and lower valve ports in the valve body, the left and right sides of the upper rhombus of the double rhombus frame are provided with a left plug and a right plug for plugging the pair of through holes, and one side of the lower rhombus of the double rhombus frame is provided with a plug for plugging the communication hole.

This solves the problem of simulating rapid ascent in traditional training, greatly enriching the training content and improving its relevance and practicality.

[0038] Automated water level management: Equipped with an automatic replenishment valve, it ensures that the water level in the simulated pool remains stable at the ideal height.

[0057] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0058] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details set forth in this description. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present application.

[0059] It is also noted that, as used herein, "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

[0060] Embodiment 1

[0061] Reference Figures 1-8 For the first embodiment of the present application, the embodiment provides a torpedo launching tube 201 simulation escape training device:

[0062] 1. Material and structural design

[0063] Transparent glass steel material application: The torpedo launching tube 201 is made of high-transparency and pressure-resistant glass steel material. This material not only has good light transmission, allowing divers to see external light in a completely dark environment and reducing psychological stress, but also ensures structural strength, making it suitable for simulating escape training in high-pressure environments. The escape pool 100 with a depth of more than 5 meters is built, and one end of the torpedo launching tube 201 is located inside the escape pool 100.

[0064] Torpedo launching tube 201 design: The torpedo launching tube 201 is equipped with a sealable front cover 202 and a rear cover 203 at both ends, which can be quickly opened and closed. The front cover 202 is equipped with a pressure balance automatic opening mechanism to ensure safe release of divers when the internal and external pressures are consistent. The front cover 202 and the rear cover 203 are also provided with a hollow interlayer 204, and the end faces of the front cover 202 and the rear cover 203 are provided with protruding insertion tubes. The first valve corresponding to the insertion tube is arranged on the end face of the torpedo launching tube 201, and the second valve is arranged in the insertion tube. When the cover is closed, the protruding insertion tube on the front cover 202 or the rear cover 203 is inserted into the first valve, so that the valve core of the second valve in the second insertion tube and the valve core of the first valve are in contact, thereby simultaneously opening and connecting the first valve and the second valve, and further connecting the interlayer 204 of the front cover 202 or the rear cover 203 with the interlayer 204 of the torpedo launching tube 201.

[0065] The torpedo launching tube 201 is internally provided with a hollow interlayer 204, the interlayer 204 is connected with a black dye circulating module 205, the black dye circulating module 205 includes a dye storage tank 205a, a pump body 205b, and a switching valve core 205d arranged in the water injection control valve 301. Before the training starts, the black dye is injected into the interlayer 204 of the torpedo launching tube 201 through the pump from the dye storage tank 205a, and the interlayer 204 is filled with the dye to create a completely black environment. After the training is completed, the dye is pumped back into the dye storage tank 205a through the switching valve core 205d and the pump, and then the clear water is pumped into the dye pipeline through the pump to enter the interlayer 204 to thoroughly flush and clean the interlayer 204, ensuring that all dye residues are removed, thereby restoring transparency.

[0066] The valve body 301a of the water injection control valve 301 penetrates the interlayer 204, the switching valve core 205d includes a pair of through holes communicating with the interlayer 204 opened on the valve body 301a, a branch pipe 205c is arranged at the lower end of the valve body 301a, the branch pipe 205c is provided with a communication hole opened on the valve body 301a, and a double rhombic frame is arranged in the valve body 301a. The upper end of the double rhombic frame is provided with an upper plug and a lower plug for plugging the upper and lower valve ports in the valve body 301a, the two sides of the upper rhombus of the double rhombic frame are provided with a left plug and a right plug for plugging the pair of through holes, and one side of the lower rhombus of the double rhombic frame is provided with a plug for plugging the communication hole. The plug includes a large plug body, a through hole is opened on the large plug body, a small plug body is arranged on one side of the large plug body, and the small plug body is fixed to the intersection shaft of the double rhombic frame installed on the large plug body through a single rhombic frame.

[0067] It should be noted that when the black dye or clear water is injected into the interlayer 204, the dye or clear water in the branch pipe 205c will push the small plug and the large plug in the communication hole to move out synchronously, and the branch pipe 205c is connected with the inside of the valve body 301a of the water injection control valve 301 at this time. Because the large plug moves out, the plug moves out as a whole to drive the lower rhombus of the double rhombic frame to deform, so that the double rhombic frame deforms, the horizontal distance is shortened, and the vertical distance is lengthened, so that the upper plug and the lower plug at the upper and lower ends of the double rhombic frame move to the upper and lower ends, and the upper valve and the lower valve in the valve body 301a are plugged, so that the upper valve separates the valve body 301a from the inner cavity of the torpedo launching tube 201, and the lower valve separates the lower end of the water injection control valve 301. At the same time, the upper rhombus also becomes shorter from left to right, so that the left plug and the right plug at the left and right ends of the upper rhombic frame move to the middle, thereby releasing the pair of through holes, so that the valve body 301a is connected with the interlayer 204, and the dye or clear water can be injected into the interlayer 204.

[0068] When the black dye or water is extracted, the pump generates suction in the branch pipe 205c, which generates suction on the small plug, causing the small plug to move further inward and disengage from the through hole of the large plug. At the same time, the small plug is fixed to one end of the lower rhombus of the double rhombus frame through the single rhombus frame, so that the single rhombus frame shortens longitudinally and lengthens laterally, thereby pushing the lower end of the double rhombus frame inward, causing the double rhombus frame to deform, the lateral distance to shorten, and the longitudinal distance to lengthen. At this time, as when injecting, the upper plug and the lower plug are blocked, and the left plug and the right plug are opened, connecting the interlayer 204 and performing extraction.

[0069] The intersection of the double rhombus frame is provided with a torsion spring for resetting. When extraction or injection is not performed, the branch pipe 205c and the interlayer 204 are blocked, and the water injection control valve 301 body is connected.

[0070] 2. Intelligent water injection adjustment module 300.

[0071] Water injection control valve 301 design: A precise programmable electric water injection control valve 301 is installed at the bottom of the torpedo launching tube 201. The valve is controlled by a microprocessor and can accurately adjust the water flow rate according to the preset program.

[0072] Pressure control algorithm: Real-time monitoring of the pressure difference inside and outside the tube is realized by using a pressure sensor. The target pressure change rate is calculated by the following formula (taking the simulation of rapid ascent as an example): the pressure change follows the formula Pt=P0*2t / 4, where Pt is the current pressure (unit: kPa), P0 is the initial pressure (101.3 kPa), and t is the time (unit: seconds). By adjusting the water injection rate, the pressure inside the tube increases according to this law, simulating the pressure change during the rapid ascent process.

[0073] 3. Automatic liquid supplementing system.

[0074] Liquid supplementing valve control logic: An automatic liquid supplementing valve with a liquid level sensor is installed at the top of the escape pool 100. The threshold is set to automatically open the liquid supplementing when the water level is lower than 20 cm of the 5-meter scale, and to automatically close when the water level reaches or exceeds the 5-meter scale. A PID controller is used to ensure stable liquid level and improve the continuity and safety of training.

[0075] Further, to improve the realism, safety and efficiency of training, and to solve the psychological fear of divers, individualized and efficient escape training is realized. On the basis of the original transparent glass steel torpedo launching tube 201 and the simulated escape pool 100, the intelligent dynamic pressure adaptation system (IDPAS) and virtual reality technology (VR) are integrated.

[0076] Pressure monitoring module 400---intelligent dynamic pressure adaptation system (IDPAS).

[0077] Pressure sensor network: High-precision pressure sensor arrays are installed on the inner walls of the torpedo launch tube 201 to monitor the internal pressure distribution in real time. The data is transmitted to the central processing unit (CPU) in real time.

[0078] Adaptive algorithm: A pressure control algorithm based on deep learning is developed to dynamically adjust the water injection speed and pressure curve according to the diver's physiological indicators (such as heart rate, breathing rate) and training progress, ensuring that the training is both challenging and safe. The pressure change formula is dynamically adjusted as follows: Pt = Pbase x f(t, HR, BR), where Pt is the current pressure, Pbase is the base pressure, and f(t, HR, BR) is an adaptive function that combines time t, heart rate (HR), and breathing rate (BR), ensuring that the training intensity matches the diver's state.

[0079] Virtual reality (VR) environment simulation module.

[0080] Immersive VR experience: Divers are equipped with integrated VR headsets that simulate real marine environments and various emergency escape scenarios, such as night, severe weather, and complex seabed terrain.

[0081] Interactive training content: Combined with IDPAS, the virtual environment can respond to changes in internal pressure in real time, presenting corresponding visual and auditory feedback (such as ear pressure caused by water pressure, water flow sound, etc.), enhancing the immersion and ability to respond to unexpected situations during training.

[0082] Training management system 600 includes safety enhancement measures, training effectiveness evaluation and feedback.

[0083] Safety enhancement measures.

[0084] Physiological monitoring and warning system: Integrates heart rate monitoring, blood oxygen saturation detection, and other functions. Once the diver's physiological indicators are abnormal, an alarm is triggered immediately and the training intensity is automatically adjusted. If necessary, the emergency drainage and rapid opening program is started.

[0085] Remote monitoring and guidance: The entire training process is monitored remotely through a cloud platform. Coaches can view the diver's status in real time and provide immediate guidance through voice communication. If necessary, they can intervene.

[0086] Training effectiveness evaluation and feedback.

[0087] Data analysis platform: Collects data from each training, including physiological response, operation accuracy, completion time, etc. AI analysis generates personalized training reports and provides improvement suggestions.

[0088] Virtual review and simulation: After training, use VR technology to review the scene, allowing divers to observe their own operations from different perspectives, deepen their understanding, and promote skill improvement.

[0089] Conclusion: By integrating intelligent dynamic pressure adaptation systems, virtual reality technology, and comprehensive safety monitoring systems, this improved scheme greatly enhances the comprehensive effectiveness of the torpedo tube 201 simulation escape training, not only effectively alleviating the psychological fear of divers, but also achieving personalized adaptive training difficulty, significantly improving the safety, efficiency, and practicality of training, and providing divers with a near-real escape skill training environment.

[0090] In this embodiment: The torpedo tube 201 simulation escape training method is progressive, aiming to gradually improve the adaptability and escape skills of divers in different environments, ensuring their safe and effective execution of tasks in various complex and extreme conditions. The following is a detailed explanation of this training progression strategy:

[0091] Initial stage: Transparent simulator training.

[0092] Purpose: In the early stages of training, the focus is on familiarizing divers with the escape process and basic operations while reducing their psychological stress. Use a transparent glass steel torpedo tube 201 simulator with sufficient internal light, allowing divers to visually perceive the external environment and reduce the fear of enclosed spaces.

[0093] Benefits: In this way, divers can build confidence in a relatively comfortable environment, focusing on learning technical details and mastering basic skills, laying a solid foundation for subsequent more rigorous training.

[0094] Mid-stage: Full-enclosed lightless environment training.

[0095] Purpose: As divers become proficient in basic operations, the training environment gradually approaches real conditions by removing light and simulating a truly enclosed dark environment. This step is to enhance the adaptability and psychological endurance of divers in lightless environments, as the actual emergency situation may be completely dark inside the torpedo tube 201.

[0096] Challenge: This stage of training tests divers' psychological qualities and positioning and navigation abilities in the dark, helping to improve their decision-making and action efficiency under pressure.

[0097] Later stage: Virtual reality (VR) technology superimposed extreme environment simulation.

[0098] Purpose: After divers have basic escape skills and dark environment adaptation capabilities, virtual reality technology is introduced to create various extreme environmental conditions for simulation training, such as adverse weather, complex seabed terrain, night vision conditions, etc. This step greatly expands the diversity and complexity of training.

[0099] Advantages: VR technology makes the training scene infinitely close to real combat, not only improving the realism of training, but also adjusting the training difficulty in real time according to the performance of the trainee, realizing individualized training. In addition, it allows to simulate those situations that are difficult to replicate or extremely risky in reality in a safe environment, further improving the emergency preparedness and adaptability of divers.

[0100] Summary: This phased environmental adaptation training strategy gradually transitions from intuitive and controllable transparent simulation to fully enclosed and lightless, and finally integrates VR technology to simulate extremely complex environments, gradually improving the psychological adaptation ability, technical proficiency and emergency response speed of divers, and making comprehensive preparations for various challenges that may be encountered in actual operation.

[0101] Example 2

[0102] Reference Figures 1-3 , the second embodiment of the present application, which is different from the previous embodiment, provides a simulation of rapid ascent escape training project:

[0103] Step 1: System preparation and initialization.

[0104] Equipment inspection: Ensure that each part of the torpedo launch tube 201 escape device, including the torpedo launch tube 201, programmable water injection control valve 301, pressure sensor, physiological monitoring equipment and VR system, is in good working condition.

[0105] Parameter setting: preset the rapid ascent escape training mode in the control application, set the initial pressure P0 as 1 atmosphere (about 101.3 kPa), and set the safety threshold according to the estimated maximum bearing water pressure of the torpedo launch tube 201 length and the depth of the escape pool 100.

[0106] Step 2: Divers in position and physiological monitoring connection.

[0107] Diver preparation: the diver wears professional diving equipment, including a breathing apparatus, and connects physiological monitoring equipment such as a heart rate monitor and an oxygen saturation sensor.

[0108] Enter the torpedo launch tube 201: open the back cover 203 of the torpedo launch tube 201, the diver wears the equipment under supervision, enters the torpedo launch tube 201 to the front end position through the back cover 203, and the back cover 203 is closed immediately and confirmed to be sealed.

[0109] Step 3: Training mode activation and pressure control.

[0110] Mode start: the training command center starts the rapid ascent escape training through the application.

[0111] Pressure dynamic adjustment: Adopting the optimized pressure control algorithm, the water inflow rate is accurately adjusted through the water injection control valve 301. The pressure change follows the formula Pt = P0 * 2t / 4, where Pt is the current pressure (unit: kPa), P0 is the initial pressure (101.3 kPa), and t is the time (unit: seconds), ensuring that the pressure in the pipe doubles every 4 seconds until it is equal to the water surface pressure of the pool.

[0112] Physiological state monitoring: Throughout the process, the diver's physiological indicators are continuously monitored. If abnormalities occur, the training intensity is immediately adjusted through the algorithm or emergency measures are taken.

[0113] Step four: automatic cover opening and autonomous ascent.

[0114] Pressure balance and cover opening: When the pressure in the torpedo launch tube 201 is balanced with the water level pressure of the escape pool 100, the front cover 202 is automatically opened through pressure sensing, ensuring the safe release of the diver.

[0115] Quick ascent guidance: After receiving the instructions, the diver freely ascends to the water surface according to the training guidelines.

[0116] Step five: training evaluation and feedback.

[0117] Data collection: After the training, all training data is immediately collected, including physiological parameter changes, ascent time, operation accuracy, etc.

[0118] Personalized feedback: Through AI algorithm analysis of training data, a personalized training report is provided for the diver, pointing out improvement points and next training suggestions.

[0119] Among them, the environment is gradually adjusted according to the training situation. In the initial stage, it is carried out in a transparent simulator, in the middle stage, it is carried out in a completely closed and light-free simulation environment, and in the later stage, virtual reality (VR) technology is used to superimpose extreme environment simulation for training, increasing the complexity of training.

[0121] Example 3

[0122] Reference Figures 1-3 The third embodiment of the present invention is different from the previous embodiment. This embodiment provides a simulation decompression escape training project:

[0123] Step One: System Configuration and Presetting.

[0124] Hardware Check: Ensure that the transparent fiberglass material of the torpedo tube 201 simulation device 200, programmable water injection control valve 301, pressure sensors, and the automatic liquid replenishment system inside the escape tank 100 are in optimal working condition.

[0125] Software Settings: In the control application, select the decompression escape training mode, and preset parameters including: the time required for pressure balance at both ends 300 seconds, and the depth and time of subsequent floating (4 meters deep for 5 minutes, 2 meters deep for 2 minutes).

[0126] Step Two: Diver Preparation and Physiological Monitoring.

[0127] Diver Equipment: The diver is fully dressed, including breathing apparatus, waterproof communication equipment, and physiological monitoring devices such as heart rate and blood oxygen saturation monitors.

[0128] Safety Briefing: A detailed safety operation briefing is conducted before training to ensure that the diver understands the importance of decompression stops and their operation process.

[0129] Step Three: Precise Water Injection and Pressure Balance Control.

[0130] Pressure Balance Start: Adjust the water injection control valve 301 through the application to accurately control the water injection rate, so that the time required for the pressure balance between the gas in the torpedo tube 201 and the water level pressure in the escape tank 100 is accurately controlled within 300 seconds.

[0131] Dynamic Adjustment: Use algorithms to monitor the pressure difference between the inside and outside of the tube in real time, and dynamically fine-tune the water injection rate according to actual pressure changes to ensure safe and effective pressure balance.

[0132] Step Four: Decompression Stop Procedure.

[0133] Front Cover 202 Opening: After pressure balance, the front cover 202 of the torpedo tube 201 is automatically or manually opened according to preset conditions, and the diver enters the escape tank 100.

[0134] 4-meter Depth Stop: The diver immediately moves to 4 meters deep in the tank and grabs the pre-set suspended ladder 101, stays for 5 minutes according to the instructions, and performs the initial decompression.

[0135] 2-meter Depth Stop: Then, the diver slowly floats to 2 meters below the surface of the tank, grabs the suspended ladder 101 again, and stays for 2 minutes as required for the second stage of decompression.

[0136] Safe Floating: After completing all the stop procedures, the diver slowly floats to the surface according to the standard decompression procedures, completing the decompression escape simulation training.

[0137] Step five: physiological data collection and analysis.

[0138] Data recording: During the training process, all physiological data (heart rate, blood oxygen saturation, etc.) are recorded in real time.

[0139] Effect evaluation: After the training, the diver's physiological data and training performance are analyzed by the algorithm, a personalized training report is generated, and improvement suggestions are put forward.

[0140] Among them, the environment is gradually adjusted according to the training situation, the initial stage is carried out in the transparent simulator, the middle stage is carried out in the completely closed and light-free simulation environment, and the late stage adopts virtual reality (VR) technology to superimpose extreme environment simulation for training, increasing the training complexity.

[0141] The optimization of this scheme is that a precise control algorithm is used to dynamically adjust the water injection rate, ensuring the accurate achievement of pressure balance within 300 seconds. Compared with fixed rate water injection, it is closer to the actual situation, improving the simulation and safety of the training. At the same time, combined with physiological monitoring and personalized data analysis, it not only improves the scientificity of the training, but also provides customized feedback and progress path for divers, which is a significant improvement over the existing technology.
