Description

Technical Field

[0001] This invention relates to the field of electrical skills training technology, and in particular to a psychological adaptation training device for confined space operations. Background Technology

[0002] Confined spaces refer to any poorly ventilated equipment, facilities, and locations that are prone to accumulating toxic and harmful gases and causing oxygen deficiency. Specifically, any work performed within a production area that involves entering or probing furnaces, towers, kettles, tanks, silos, tank trucks, as well as enclosed or semi-enclosed facilities and locations such as pipelines, flues, tunnels, sewers, ditches, pits, wells, pools, and culverts is considered confined space work.

[0003] Confined space operations involve a wide range of industries, including coal mines, non-coal mines, chemical plants, oil refining, metallurgy, construction, power generation, papermaking, shipbuilding, building materials, municipal engineering, urban gas supply, wastewater treatment, and special equipment. Therefore, accidents occurring during confined space operations can be quite widespread.

[0004] With the continuous development of industries such as manufacturing, power, and emergency rescue, workers often need to work in confined spaces. However, confined space environments are often accompanied by significant psychological stress and discomfort, with some even developing confined space phobia, severely impacting work efficiency and safety. Therefore, developing a training device that can effectively help workers overcome confined space phobia and improve their psychological adaptability is particularly important.

[0005] To address the need for confined space work skills training, a confined space work psychological adaptation training device was developed. This device constructs confined space work environments such as cable trenches, power cable tunnels, sealed tanks, emergency rescue scenarios, elevators, and enclosed / semi-enclosed spaces within a virtual environment. Through this virtual-real fusion, the device recreates a multi-dimensional representation of the real confined space environment, allowing trainees to see, touch, and feel it. By monitoring the trainees' psychological state in the immersive work scenario in real time, personalized adaptive training programs are provided. Trainees are placed in the accident scenario from a first-person perspective, participating in the entire work process, improving their psychological adaptability to confined space work, enhancing training safety, and preventing accidents. Summary of the Invention

[0006] The purpose of this invention is to provide a confined space psychological adaptation training device. This device can recreate the on-site environment of confined space operations, allowing trainees to immerse themselves in the work scene from a first-person perspective, participate in the entire work process, and experience the oppressive and crowded feeling of confined space operations. This solves the problem that existing psychological adaptation training models for confined space operations lack physical objects for operation and have poor training effects.

[0007] The first aspect of this invention provides a psychological adaptation training device for confined space operations, comprising:

[0008] The system includes a graphics processing service terminal, an environment simulation unit, a head-mounted display terminal, a psychological state monitoring terminal, a tracked walking platform, an infrared detection unit, a manual / automatic control unit, a touch screen, an environmental parameter display unit, and a psychological state indication unit, an identity information recognition unit, an infrared detection unit, a communication unit, and an output control unit connected to the graphics processing service terminal.

[0009] The manual / automatic control unit is connected to the output control unit and is used to control the environmental simulation unit to operate automatically or manually.

[0010] The environment simulation unit is connected to the output control unit and is used to simulate various environmental parameters of the confined space to create a realistic confined space environment.

[0011] The environmental parameter display unit is connected to the output control unit and is used to display the real environmental parameter values ​​of the environment in which the trainee is currently located in real time.

[0012] The head-mounted display terminal is connected to the graphics processing service terminal through the communication unit and is used to display virtual confined space operation scenarios;

[0013] The graphics processing service terminal is used to provide virtual scene computing support, simulate a real confined space working environment, and connect to the head-mounted display terminal via LAN to provide virtual scene signals;

[0014] The psychological state monitoring terminal, worn by trainees, is used to collect data on changes in the trainees' initial psychological state while working in a real-world task environment. The psychological state change data includes: heart rate indicators, heart rate variability indicators, and blood oxygen saturation.

[0015] The psychological state indication unit is connected to the psychological state monitoring terminal through the communication unit and is used to display the psychological state change data of the trainees.

[0016] The infrared detection unit is used to collect the standing position of the trainee on the tracked walking platform and to detect whether there is an operator in front of the touch screen.

[0017] The identity information recognition unit is used to collect and recognize the facial information of trainees for identity verification and information recording;

[0018] The tracked walking platform is connected to the output control unit and is used to train personnel to walk on it to simulate inspection operations.

[0019] The touch screen is used to synchronously display the virtual scene where the trainee is currently located. It is connected to the graphics processing service terminal via a high-definition cable. When the trainee performs walking inspection work through the head-mounted display terminal, the scene experienced by the trainee is transmitted to the touch screen for synchronous display through the graphics processing service terminal.

[0020] The fundamental reason for insufficient psychological adaptation to confined space work lies in the lack of replication of the oppressive feeling of a real confined environment in traditional training, preventing trainees from repeatedly experiencing and overcoming their fear under safe conditions. To address this, this technical solution integrates visual immersion, physical environment simulation, natural walking, and real-time physiological monitoring into a closed-loop system. The graphics processing service terminal and head-mounted display terminal construct realistic virtual confined scenarios such as cable trenches and tunnels, allowing trainees to immerse themselves in these environments from a first-person perspective, seeing exactly what they see. The environmental simulation unit simultaneously outputs physical parameters such as humidity, airflow, sound, and light, giving trainees a tangible experience. The tracked walking platform allows trainees to walk realistically within the confined space, further enhancing physical immersion. Simultaneously, the psychological state monitoring terminal and indicator unit collect and intuitively report indicators such as heart rate and blood oxygen, making previously invisible psychological stress levels transparent and quantifiable. This device fundamentally solves the industry pain points of lacking physical objects for operation and training being detached from reality, achieving a virtual-real fusion and multi-sensory collaboration in confined space psychological adaptation training. This significantly improves training immersion and effectiveness, allowing trainees to gradually desensitize in a safe environment and reducing the risk of safety accidents during real-world work.

[0021] Based on the above, the environmental simulation unit includes an air supply module, a cold air module, a flashing module, a voice module, a hot air module, and a humidification module;

[0022] The air supply module is used to supply air to the inside of the training device cabinet; the cold air module is used to generate low-temperature cold air; the flashing module is used to generate flashing effects to simulate abnormal cable operation in a confined space environment; the voice module is used to simulate sound effects in a confined space environment and provide voice prompts to guide training; the hot air module is used to simulate the humid and hot effect in a confined space environment; and the humidification module is used to simulate the humid and hot effect in a confined space environment.

[0023] The psychological stress caused by confined spaces stems not only from the visual narrowness and darkness, but also from the physical sensations of stuffiness, humidity, odors, unusual noises, and sudden flashes of light. If only visual virtual scenes are provided, training will be limited to observation and will fail to truly stimulate trainees' stress responses, significantly diminishing the training effect. Therefore, an environmental simulation unit integrating air supply, cooling, heating, humidification, flashing lights, and voice commands was specifically designed. The modules work together to reproduce the high temperature and humidity of cable trenches, the cold airflow of tunnels, the flashing lights during equipment malfunctions, and various environmental noises and voice commands. This approach overcomes the shortcomings of purely virtual reality training, which only provides a visual experience without immersive feeling. It engages trainees' senses of touch, hearing, and even temperature, allowing them to truly experience the oppression and discomfort of working in confined spaces. This greatly enhances the realism of the training environment and the psychological immersion, upgrading psychological adaptation training from visual simulation to a multi-sensory, deeply integrated experience. Trainees' physiological and psychological reactions are closer to real-world working conditions, thus significantly improving the efficiency of desensitization training.

[0024] Based on the above, the communication unit includes a Bluetooth communication unit and a LAN communication unit;

[0025] The psychological state indication unit is connected to the psychological state monitoring terminal via the Bluetooth communication unit;

[0026] The head-mounted display terminal is connected to the graphics processing service terminal via the LAN communication unit.

[0027] Psychological monitoring data requires real-time, unrestricted transmission, while virtual reality video signals demand extremely high bandwidth and low latency; the transmission characteristics of the two differ significantly. Using a single communication method would inevitably compromise one aspect, leading to monitoring delays or video stuttering, severely impacting the real-time nature and safety of training. Therefore, the communication unit was specifically designed with a dual-mode architecture of Bluetooth and LAN. The psychological state monitoring terminal connects wirelessly via Bluetooth, allowing trainees to walk freely on the tracked platform without being restricted by cables, ensuring stable transmission of physiological data. The head-mounted display terminal connects wired via LAN, guaranteeing uncompressed, low-latency transmission of high-definition virtual scene signals and preventing motion sickness. This design solves the problems of mutual interference and bandwidth bottlenecks in the concurrent transmission of multiple data types, ensuring smooth and stable visuals and real-time synchronization of psychological indicators during immersive training, providing a reliable communication foundation for accurately assessing trainees' states and dynamically adjusting training difficulty.

[0028] Based on the above, it also includes a training device cabinet; the training device cabinet is used to house the graphics processing service terminal, the environment simulation unit, the head-mounted display terminal, the tracked walking platform, the manual / automatic control unit, the touch screen, the environmental parameter display unit, the psychological state indication unit, the communication unit, and the output control unit.

[0029] Constrained space psychological training involves numerous sophisticated and dispersed pieces of equipment. Temporary setup is not only time-consuming and labor-intensive, but also makes it difficult to maintain stable environmental parameters and ensure consistent training conditions for each session. Therefore, this paper proposes integrating all core functional units into a single training cabinet. This cabinet serves as both a physical platform and a controlled environment container—modules for air supply, temperature and humidity control, and sound and light all function within the cabinet, ensuring a standardized and repeatable training environment. This integrated design solves the problems of dispersed training equipment, uncontrollable environmental variables, and difficulties in deployment and relocation, creating a unified and mobile confined space psychological adaptation training system. This makes training more convenient, provides more uniform training conditions, significantly reduces the venue dependence and maintenance costs for training institutions, and contributes to the establishment of a standardized training system.

[0030] Based on the above, the training device cabinet is equipped with a storage compartment, an ultraviolet disinfection module, and electrically controlled glass;

[0031] The storage compartment is used to house the head-mounted display terminal and to charge the head-mounted display terminal;

[0032] The ultraviolet disinfection module is installed inside the storage compartment and is used to disinfect the head-mounted display terminal placed in the storage compartment.

[0033] The electrically controlled glass is installed on the surface of the movable door of the training device cabinet and is electrically connected to the output control unit. It is used to control the environment inside the training device cabinet to isolate it from the external environment as needed for training.

[0034] VR headsets come into direct contact with trainees' facial skin, posing a risk of cross-infection if not disinfected promptly. Furthermore, if the environment inside and outside the training cabinet is connected, external light, airflow, and sound can disrupt the immersive, enclosed feeling of the restricted space. To address this, a storage compartment, an ultraviolet disinfection module, and electrically controlled glass were added to the training cabinet. The storage compartment also serves as a charging compartment, allowing the headset to be charged immediately upon storage, ensuring the equipment is always available. The ultraviolet disinfection module automatically or periodically disinfects the headset after it is placed inside, eliminating hygiene risks at the source. The electrically controlled glass allows for segmented adjustment of transparency or closure during training, completely isolating the virtual, restricted environment created inside the cabinet from the outside world. This design solves the problems of difficult hygiene control for immersive training equipment and susceptibility to external interference in the training environment. While ensuring trainees' health, it further strengthens the enclosure and isolation of the training space, putting trainees in a restricted space psychological state from the moment they enter the training cabinet, improving the standardization of training and the psychological suggestion effect.

[0035] The first aspect of this invention provides a training method based on the confined space work psychological adaptability training device, comprising:

[0036] A confined space work scene that mimics the real work environment is constructed in the virtual scene of the graphics processing service terminal using 3D modeling, and then sent to the head-mounted display terminal for display.

[0037] During training:

[0038] After the trainees put on the head-mounted display terminal and the psychological state monitoring terminal, they stood on the tracked walking platform.

[0039] After the infrared detection unit detects that a trainee has stepped onto the tracked walking platform, it controls the tracked walking platform to begin patrol and training operations; simultaneously...

[0040] The graphics processing service terminal controls the environment simulation unit to simulate and output various environmental parameters of the confined space through the output control unit.

[0041] During the training process, the psychological state monitoring terminal collects data on changes in the psychological state of the trainees and performs quantitative evaluation on the collected data.

[0042] The head-mounted display terminal receives a confined space operation scene virtually constructed and generated in the graphics processor, and personnel conduct patrols in the virtual confined scene.

[0043] The environmental simulation unit is set to automatic or manual operation mode;

[0044] In automatic mode, the graphics processor automatically sends signals to the output control unit based on the behavior of elements in the scene, and the environment simulation unit simulates and outputs various environmental parameters of the confined space.

[0045] In manual mode, the graphics processor receives instructions and sends signals to the output control unit, and the environment simulation unit simulates and outputs various environmental parameters of the confined space.

[0046] After the infrared detection unit detects that a trainee is standing on the tracked walking platform, it controls the tracked walking platform to operate.

[0047] During the training process, the psychological state monitoring terminal collects data on changes in the psychological state of the trainees and performs quantitative evaluation on the collected data. Through multiple training sessions and positive feedback from comparing changes in psychological state data, the psychological adaptability of personnel in confined space inspection and maintenance scenarios is ultimately improved, meeting the physical fitness requirements of personnel performing confined space operations.

[0048] This method begins with automatic infrared detection-triggered training, ensuring a smooth process and minimizing manual intervention. Through the automatic mode of the environmental simulation unit, events in the virtual scene (such as entering a deep tunnel or abnormal equipment flashes) trigger corresponding physical parameter outputs in real time, creating a synchronized interaction of sight, hearing, and touch to enhance trainees' stress response experience. The manual mode provides instructors with flexible intervention options, facilitating targeted training. Most importantly, the method combines multiple training sessions with longitudinal comparisons of psychological state data, guiding trainees to gradually adapt through positive feedback. This training method addresses the problems of previous training methods that only involved instruction without evaluation and lacked progress. It establishes a closed-loop training mechanism of immersive experience—real-time monitoring—quantitative assessment—desensitization feedback, making the psychological adaptability improvement process visible, traceable, and repeatable, ensuring that systematically trained personnel truly achieve the physical and mental qualities required for confined space work.

[0049] Based on the above, the method for quantitatively evaluating the collected data on changes in psychological state is as follows:

[0050] Quantitative analysis is performed using heart rate indicators, heart rate variability indicators, and blood oxygen saturation. When the comprehensive indicator is greater than the threshold for 10 seconds, it is displayed in red; when the comprehensive indicator is near the threshold, it is displayed in yellow; and when the comprehensive indicator is less than the threshold for 10 seconds, it is displayed in green.

[0051] To address the core challenge of the invisibility and inaccuracy of assessing psychological states, three physiological indicators most sensitive to stress and fear and easily collected continuously were selected: heart rate, heart rate variability, and blood oxygen saturation. A comprehensive indicator system was established with thresholds set, displayed visually using red, yellow, and green: red represents sustained high stress, warning trainees and instructors of the need for adjustment; yellow indicates a critical state; and green signifies a stable psychological state. This quantitative assessment method transforms vague psychological feelings into objective physiological data, filling the industry gap in the lack of quantitative indicators for psychological training. It enables real-time safeguarding of training safety, preventing trainees from suffering physical and psychological harm due to excessive stress. Simultaneously, it provides a basis for personalized desensitization training; instructors can adjust training intensity based on color changes, helping trainees learn self-awareness and regulation, ultimately achieving efficient psychological adaptation goals.

[0052] The features and beneficial effects of this invention are as follows:

[0053] This invention's device constructs confined space work environments such as cable trenches, power cable tunnels, sealed tanks, emergency rescue, elevators, and enclosed / semi-enclosed spaces within a virtual scene on a head-mounted display terminal. It simulates real-world environmental parameters through an environmental simulation unit, achieving a multi-dimensional, virtual-real fusion of the real and the virtual, allowing trainees to see, touch, and feel the immersive work environment. By monitoring the trainees' psychological state in the immersive work scenario in real time, it provides personalized adaptive training programs. This allows trainees to immerse themselves in the accident scenario from a first-person perspective, participating in the entire work process, improving their psychological adaptability to confined space work, enhancing training safety, and preventing accidents.

[0096] In automatic mode, the graphics processor automatically sends signals to the output control unit based on the behavior of elements in the scene, and the environment simulation unit simulates and outputs various environmental parameters of the confined space.

[0097] In manual mode, the graphics processor receives instructions and sends signals to the output control unit, and the environment simulation unit simulates and outputs various environmental parameters of the confined space.

[0102] Example 3

[0103] This embodiment uses the psychological training scenario of power cable tunnel inspection operations as an example to illustrate the training method:

[0104] Regular inspections of power cable tunnels are conducted, and trainees follow standard operating procedures to carry out these inspections. Trainees prepare for the work by gathering tools, protective equipment, etc. They enter the tunnel through a simulated entrance, where the training equipment activates humidification, heating, and ventilation modules to create a realistic cable trench environment. This allows trainees to experience firsthand the impact of the cable trench work environment on their physical movements and the effects of high temperature and humidity on their physical and mental well-being.

[0105] Trainees conduct inspections, checking whether the ambient temperature inside the tunnel is normal and whether there are any significant changes, whether the water level inside the tunnel is normal, whether there are any odors, dust, or dirt in the air inside the tunnel, whether the lighting inside the tunnel is normal, and whether there is any damage, looseness, or deviation of the road surface or facilities. The inspection personnel prepare an inspection record form, including the inspection date, the name of the inspector, the inspection location, the inspection results and any abnormalities, and the date of the next inspection.

[0106] Inspection personnel conduct a comprehensive inspection of the cable tunnel's interior, including the cable arrangement and securing status. Detailed inspection records are kept, including the date, personnel, inspection content, problems encountered, and their resolution. Trained personnel complete an inspection report, summarizing the inspection findings, identifying problems, and proposing solutions. The inspection report is then submitted to the relevant departments.

[0107] The psychological state monitoring module monitors the trainees' psychological state in real time, analyzes the psychological changes of the trainees during cable tunnel inspection tasks through data analysis, and provides an assessment plan.

[0108] Example 4

[0109] This embodiment uses the scenario of psychological adaptation training in deep pit operations as an example to illustrate the training method:

[0110] Deep pit operations are extremely dangerous, as accidents often occur suddenly and are difficult to predict and prevent. Deep pits may contain hazards such as oxygen deficiency, toxic gases, and collapses, posing significant risks to rescue personnel. Deep pit rescues require specialized equipment and skills, and are also hampered by spatial limitations, making rescue operations difficult to conduct.

[0111] The system uses virtual reality technology to construct a deep pit working environment, trains personnel to adapt to the environment, monitors personnel's psychological changes, provides quantitative assessments, and offers assessment plans for guided training.

[0112] A deep pit operation environment was constructed using virtual reality technology to train personnel in emergency rescue capabilities based on standard procedures in such an environment.

[0113] Initial assessment: Upon arrival at the scene, rescue personnel should first ascertain the condition of the pit, including its depth, shape, and geological conditions. They should then assess the condition of the trapped individuals, including their level of consciousness and injuries.

[0114] Safety precautions: Rescue personnel must wear appropriate personal protective equipment, such as helmets, protective suits, gloves, and safety shoes. Safety warning signs should be set up to ensure safety at the rescue site.

[0115] Establish communication: Establish communication with the trapped personnel to ascertain their location and status. If direct communication is not possible, information can be transmitted through methods such as knocking or shouting.

[0116] Rescue preparation: Based on the characteristics of the pit and the situation of the trapped personnel, select appropriate rescue equipment and tools. If necessary, a rescue platform or rescue ladder can be set up.

[0117] Rescue Operation: Rescuers should enter the pit slowly and steadily to avoid causing secondary injuries. Use rescue equipment to pull the trapped person out, taking care to protect their head, neck, and spine. If the trapped person is injured, provide initial treatment as soon as possible and then transport them to a hospital for further treatment.

[0118] During the simulated rescue process, the trainees' use of rescue equipment, rescue methods, rescue measures, and operating procedures are tested, and their psychological changes are monitored. A multi-dimensional quantitative assessment is given to comprehensively evaluate the trainees' rescue skills.

[0119] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
