Description

Technical Field

[0001] The present invention relates to the field of aviation firefighting and rescue equipment, and in particular to an airport firefighting and rescue multi-role collaborative training system based on virtual reality technology. Background Art

[0002] Firefighting and rescue capabilities are crucial to ensuring airport safety during airport operations. Traditional airport firefighting and rescue training methods have many limitations and are unable to meet the needs of modern airports for efficient and precise firefighting and rescue.

[0003] Field drills, as an important form of traditional training, require a large investment of human, material, and financial resources. Each field drill involves numerous fire trucks, firefighting equipment, and a large amount of fire extinguishing agents. At the same time, a large number of firefighters need to be deployed to participate. This is not only extremely costly, but also has a significant impact on the normal operation of the airport, requiring the airport to make major adjustments in flight scheduling and other aspects. In addition, the organization and coordination of field drills is extremely complex. To ensure close cooperation between various departments and rescue forces, it involves precise control of multiple links. Problems in any link may greatly reduce the effectiveness of the drill. More importantly, field drills are difficult to fully simulate various complex, changeable, and extremely dangerous fire scenarios, such as large passenger aircraft fully loaded with fuel catching fire, three-dimensional combustion inside airport buildings, etc. There are high safety risks in actual operations, which cannot allow firefighters to fully experience and respond.

[0004] While relatively simple to organize and implement, tabletop exercises suffer from a significant lack of support for situational awareness. During tabletop exercises, firefighters primarily visualize fire scenarios through text, images, and verbal descriptions. This approach lacks intuitiveness and immersion, making it difficult for rescuers to truly experience the tense atmosphere, dynamic changes in the fire's spread, and complex environmental factors. This can hinder quick and accurate judgment and decision-making when faced with a real fire, hindering their ability to effectively translate theoretical knowledge learned in tabletop exercises into practical response capabilities.

[0005] With the continuous development of virtual reality technology, it has shown tremendous potential for application in firefighting and rescue training. Some existing technologies have attempted to utilize virtual reality technology to build firefighting and rescue training systems, but these technologies still have numerous shortcomings. Some systems focus solely on creating virtual scenes. While they can present a certain degree of fire scene imagery, they lack realism and detail. They cannot accurately simulate the physical characteristics of a fire scene, such as heat transfer, smoke spread, and flame patterns. This makes it difficult for firefighters to accurately perceive the actual fire scene during training. Furthermore, most existing systems have significant shortcomings in multi-role collaborative training. Imperfect interaction mechanisms between different roles and unsmooth information transfer make it difficult to achieve close coordination and cooperation among different roles in complex rescue scenarios, thus failing to achieve the training goal of improving the overall collaborative combat capabilities of airport firefighting and rescue operations. To address the shortcomings of current virtual reality training, the present invention designs a virtual reality airport firefighting and rescue multi-role collaborative training system and method that can highly simulate real fire scenes and effectively support multi-role collaborative training. The system supports real-time operation demonstrations, error correction, and multimodal interaction, and integrates evaluation to optimize training results. This improvement is in line with the development trend of intelligent and collaborative aviation firefighting training, can significantly enhance emergency response capabilities and training efficiency, and has important engineering application value. Summary of the Invention

[0017] The control module is used to manage the entire process of the evolution calculation of airport emergency events, ensuring that the simulation logic is consistent with the training objectives, and at the same time achieving rapid intervention in abnormal conditions.

[0018] Furthermore, the VR individual firefighting system includes a head-mounted display device, a joystick, and a somatosensory vest;

[0019] The head-mounted display device is used to provide an immersive visual experience of an aircraft fire scene;

[0020] The joystick is used to simulate various activities and interactive operations, so that the trainees' physical movements are converted into virtual firefighting operations;

[0021] The somatosensory vest is used to provide immersive tactile feedback, allowing trainees to intuitively feel the physical stimulation of the fire environment.

[0022] Furthermore, the fire truck driving fire extinguishing system includes a simulated cockpit, a multi-screen splicing display module, a fire extinguishing operation simulation device and a data acquisition and control module;

[0023] The simulated cockpit is a 1:1 replica of a real fire truck cockpit, equipped with but not limited to a steering wheel, accelerator, brake, gear lever, lighting control, and siren switch operating components, and the steering wheel steering resistance and accelerator pedal feedback are consistent with those of a real vehicle, to provide a realistic cockpit environment;

[0024] The multi-screen splicing display module is used to build a 360-degree immersive visual environment, presenting road scenes, fire scene images, vehicle dashboard data and surrounding environment information in real time;

[0025] The fire extinguishing operation simulation device includes a fire information display front screen, fire function buttons and main and auxiliary water monitor joysticks for real-time vehicle fire extinguishing simulation device operation;

[0026] The data acquisition and control module is used to calculate the vehicle's motion state in real time, drive the update of parameters in the virtual scene including but not limited to the position, speed, and acceleration of the fire truck, and render the virtual visual image in real time.

[0027] Furthermore, the emergency command system includes an emergency command platform, a multi-host configuration module, a function configuration and designation module, and a rights management module;

[0028] The emergency command platform is used for data aggregation, real-time monitoring, decision support, and command issuance, and realizes the connection between the front-end execution equipment and the back-end command center;

[0029] The multi-host configuration module is used for distributed deployment and multi-host collaboration to achieve information interconnection and data transmission, as well as stability under high load or emergency conditions, including several control seat host groups;

[0030] The function configuration and designation modules are used by the master computer to configure the functions of all control seat computers, and to designate different control seats to flexibly configure function modules according to event types, industry scenarios, and user needs;

[0031] The authority management module is used to support the authority management function, and ensure system data security and operation compliance based on strict role division, authority allocation and operation audit.

[0032] The training method of the airport fire rescue multi-role collaborative training system based on virtual reality technology adopts the above-mentioned virtual reality airport fire rescue multi-role collaborative training system and includes the following steps:

[0033] Step 1: Construct training scenarios and role settings;

[0034] Step 2: Synchronize training startup with the scene;

[0035] Step 3: Multi-role collaborative training and linkage;

[0036] Step 4: Real-time feedback and review of training.

[0037] Furthermore, the specific method of step 1 is:

[0038] Step 1.1: Customize the training scenario: Based on the training objectives, preset the corresponding airport fire scenario parameters through the functional configuration and designated modules of the emergency command system; including fire type, fire location, fire scale, environmental conditions, and initial scenario resource distribution;

[0039] Step 1.2, multi-role division and authority and equipment configuration: On the one hand, according to the requirements of the training scenario, three core roles are assigned; including the role of fire fighter, who uses the VR individual fire extinguishing system and is responsible for front-line firefighting operations, personnel search and rescue, and on-site fire feedback; the role of fire truck driver, who uses the fire truck driving fire extinguishing system and is responsible for driving the fire truck to the scene quickly, accurately docking, and operating the on-board water cannon / fire extinguishing agent spray; the role of commander, who is responsible for global monitoring, resource scheduling, command issuance and cross-departmental coordination through the emergency command system; on the other hand, through the authority management module of the emergency command system, the operation authority of the corresponding system is configured for different roles; fighters obtain the operation authority of the VR individual system, drivers obtain the full function authority of the fire truck driving system, and commanders obtain the global data viewing, command issuance, and resource allocation authority of the emergency command platform, restricting the access of ordinary roles to the command module;

[0040] Step 1.3, equipment and data channel inspection: Calibrate the head-mounted display device, control handle, and somatosensory vest of the VR individual fire-fighting system to ensure that virtual operations and feedback are truly synchronized; test the simulated cockpit, multi-screen splicing display module, and fire-fighting operation simulation equipment of the fire truck driving fire-fighting system to ensure that the driving and fire-fighting operation logic are consistent with actual combat; check the emergency command platform and multi-host configuration module of the emergency command system to ensure that there is no delay in data processing and communication; start the secure data channel between systems to test the data interoperability of the VR individual system, vehicle driving system, and emergency command system; verify whether the individual soldier's position information and operation data can be transmitted to the command platform in real time, whether the vehicle's driving trajectory and fire-fighting operation parameters can be synchronized to the command screen, and whether the command instructions can be accurately pushed to the individual soldier and driver's equipment terminals to ensure that the "operation-data-feedback" closed loop is unobstructed.

[0041] Furthermore, the specific method of step 2 is:

[0042] Step 2.1: Remote control system deployment and linkage preparation: The emergency command center's remote control system is activated, with several control seat hosts deployed in a distributed manner and coordinated across multiple hosts to achieve information interconnection between the control seats of each rescue department. The heads of each rescue department log in to their corresponding control seat and complete voice communication testing through the speaker system to ensure smooth real-time communication channels across departments.

[0043] Step 2.2: Synchronous loading of multi-system scenarios: Commanders issue commands through the emergency command system, triggering each system to synchronously load preset scenarios. The VR individual firefighting system presents a 360-degree immersive fire scene to combatants through head-mounted display devices, and the somatosensory vest pre-activates the environmental tactile feedback module. The multi-screen splicing display module of the fire truck driving firefighting system loads the road environment of the corresponding scenario, and the simulated cockpit synchronously initializes the vehicle's initial state. The visual interface of the emergency command platform generates a global scene map, marking the initial fire location, the initial position of each character, and the distribution of available resources.

[0044] Step 2.3, role identity confirmation and task acceptance: Combatants and drivers log in through the authentication modules of their respective systems. The system automatically matches role permissions with scene perspectives. The emergency command system pushes initial tasks to each role, and the task content is synchronously displayed on each system terminal.

[0045] Furthermore, the specific method of step 3 is:

[0046] Step 3.1: Individual Firefighting Operations and Interactions: The soldier observes the fire situation through a head-mounted display device, including but not limited to using the joystick to simulate accessing a fire extinguisher, connecting a hose, and adjusting the angle of the water gun. The somatosensory vest provides temperature feedback based on the virtual distance from the flames, and the handle generates recoil feedback when operating the high-pressure water gun. The system collects the soldier's position, movement, operation accuracy, and firefighting duration in real time, and uploads the data to the emergency command system via a secure data channel.

[0047] Step 3.2: Firefighting vehicle driving and firefighting linkage: The driver completes operations including but not limited to vehicle starting, acceleration, steering, and obstacle avoidance in a simulated cockpit. The multi-screen display module updates road conditions and vehicle instrument panel data in real time. Upon arrival at the scene, the firefighting operation simulation device adjusts the water cannon range and angle, coordinating with the individual soldier's position to carry out firefighting. The data acquisition and control module transmits the vehicle's driving trajectory, parking position accuracy, and water cannon spray parameters to the emergency command system in real time, and simultaneously shares them with the individual soldier's system.

[0048] Step 3.3, Real-time monitoring and dispatch: The emergency command platform processes massive amounts of real-time data through a multi-host configuration module, and dynamically displays on the command screen the movement trajectory of individual soldiers, the effectiveness of fire-fighting operations, the location and status of vehicles, and the curve of fire changes in each area. Command personnel can use this to promptly grasp the rescue dynamics and make flexible decisions and adjustments to ensure the smooth progress of the rescue operation and ultimately respond to sudden aircraft fire incidents.

[0049] Furthermore, the specific method of step 4 is:

[0050] Step 4.1. Dynamic Assessment of Collaboration Status: Each subsystem integrates an intelligent monitoring module that analyzes operations in real time based on a preset library, identifying violations, inefficient, or high-risk behaviors. It then provides trainees with instant audible, visual, and vibration warnings or guidance via terminal devices. The emergency command platform aggregates multi-source data in real time to calculate and visualize key collaborative effectiveness indicators.

[0051] Step 4.2: Generate a multi-dimensional data report: The emergency command system automatically aggregates data from the three systems to generate a collaborative training report. The role performance dimension is evaluated through individual firefighting efficiency scores, driver operational standardization scores, and command decision rationality scores. The collaborative effectiveness dimension is evaluated through cross-role task response time, resource supply and demand matching, and the success rate of collaborative handling of dangerous situations, as well as the identification of collaborative weaknesses.

[0052] Step 4.3: Review, analysis, and optimization suggestions: All trainees use the emergency command platform's immersive multi-perspective review mode to simultaneously view the entire training process and analyze collaboration issues based on data reports. Optimization plans are developed for these issues and updated to the emergency command system's contingency plan library to provide a basis for improvement in subsequent training.

[0053] The beneficial effects of the present invention are:

[0054] 1. This system uses the Airport Emergency Evolution Computing Center to simulate the physical characteristics of a fire scene with high precision. Combined with the VR individual firefighting system's head-mounted display, somatosensory vest, and joystick, it provides firefighters with a realistic visual, tactile, and operational experience. The firefighting vehicle driving system replicates the cockpit at a 1:1 scale, simulating steering wheel resistance, throttle feedback, and multiple displays, giving drivers a realistic driving and firefighting experience. This high-fidelity scenario addresses the lack of intuitive perception in traditional desktop exercises and the inadequate detail reproduction of existing VR systems, making training more realistic for actual combat situations.

[0055] 2. This system uses a secure data channel to enable real-time data exchange between three major systems: individual VR soldiers, fire truck drivers, and emergency command systems. Information such as individual soldier location, operational data, vehicle trajectory, firefighting parameters, and command instructions are synchronized across systems. Commanders use the emergency command platform for comprehensive monitoring and precise dispatch. Soldiers and drivers collaborate on firefighting based on shared data. This collaborative mechanism addresses the shortcomings of existing technologies, including insufficient role interaction and poor information transfer, effectively improving the coordination of multiple departments and roles in complex scenarios, meeting the core requirements of coordinated airport firefighting operations. Compared to field drills, this system eliminates the need for extensive firefighting equipment, fire extinguishing agents, and vehicle resources, nor does it require adjustments to airport flight operations, significantly reducing both human and material costs. Furthermore, the system can safely simulate extremely dangerous scenarios, such as a fully fueled large passenger aircraft fire or a burning three-dimensional building, through virtual scenarios. This avoids the potential for casualties in field drills and addresses the high cost, high risk, and limited scenario constraints of traditional training. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] like Figure 2 This embodiment provides a method for real-time dispatch of emergency resources for aircraft fire incidents, namely, a method for airport fire rescue multi-role collaborative training based on virtual reality technology. The method uses the aforementioned airport fire rescue multi-role collaborative training system based on virtual reality and includes the following steps:

[0089] Step 1: Construct training scenarios and role settings;

[0090] Step 2: Synchronize training startup with the scene;

[0091] Step 3: Multi-role collaborative training and linkage;

[0092] Step 4: Real-time feedback and review of training.

[0093] Preferably, in step 1, specifically:

[0094] Step 1.1. Customize the training scenario (preset airport fire scenario parameters): Based on the training objectives, preset the corresponding airport fire scenario parameters through the functional configuration and designated modules of the emergency command system. This includes fire type, fire location, fire scale, environmental conditions, and initial scenario resource distribution.

[0095] Step 1.2, multi-role division and authority and equipment configuration (divide into three core roles and configure permissions): On the one hand, three core roles are assigned according to the requirements of the training scenario. Including the role of fire fighters, who use the VR individual fire extinguishing system and are responsible for front-line fire extinguishing operations, personnel search and rescue, and on-site fire feedback; the role of fire truck drivers, who use the fire truck driving fire extinguishing system and are responsible for driving the fire truck to quickly arrive at the scene, accurately dock, and operate the on-board water cannon / fire extinguishing agent spray; the role of commanders, who are responsible for global monitoring, resource scheduling, command issuance and cross-departmental coordination through the emergency command system; on the other hand, through the authority management module of the emergency command system, configure the operating permissions of the corresponding system for different roles. Fighters obtain the operating permissions of the VR individual system, drivers obtain full-function permissions of the fire truck driving system, and commanders obtain the global data viewing, command issuance, and resource allocation permissions of the emergency command platform, restricting ordinary roles from accessing the command module;

[0096] Step 1.3, equipment and data channel inspection: Calibrate the head-mounted display device, joystick, and somatosensory vest of the VR individual fire-fighting system to ensure that virtual operations and feedback are truly synchronized. Test the simulated cockpit, multi-screen splicing display module, and fire-fighting operation simulation equipment of the fire truck driving fire-fighting system to ensure that the driving and fire-fighting operation logic are consistent with actual combat. Check the emergency command platform and multi-host configuration module of the emergency command system to ensure that there is no delay in data processing and communication. Start the secure data channel between systems to test the data interoperability of the VR individual system, vehicle driving system, and emergency command system. Verify whether the individual soldier's position information and operation data can be transmitted to the command platform in real time, whether the vehicle's driving trajectory and fire-fighting operation parameters can be synchronized to the command screen, and whether the command instructions can be accurately pushed to the individual soldier and driver's device terminals to ensure that the "operation-data-feedback" closed loop is unobstructed.

[0097] Preferably, in step 2, specifically:

[0098] Step 2.1: Remote control system deployment and communication testing: The remote control system of the emergency command center is activated, with several control seat hosts deployed in a distributed manner and coordinated by multiple hosts, to achieve information interconnection between the control seats of each rescue department. The person in charge of each rescue department logs in to the corresponding control seat and completes the voice communication test through the speaker system to ensure smooth real-time communication channels across departments;

[0099] Step 2.2, multiple systems synchronously load preset scenarios: The commander issues instructions through the emergency command system, triggering each system to synchronously load the preset scenarios. The VR individual firefighting system presents a 360° immersive fire scene to the combatants through a head-mounted display device, and the somatosensory vest pre-starts the environmental tactile feedback module. The multi-screen splicing display module of the fire truck driving fire extinguishing system loads the road environment of the corresponding scene, and the simulated cockpit synchronously initializes the initial state of the vehicle. The visual interface of the emergency command platform generates a global scene map, marking the initial fire location, the initial position of each role, and the distribution of available resources;

[0100] Step 2.3, role identity confirmation and task acceptance: Combatants and drivers log in through the authentication modules of their respective systems. The system automatically matches role permissions with scene perspectives. The emergency command system pushes initial tasks to each role, and the task content is synchronously displayed on each system terminal.

[0101] Preferably, in step 3, specifically:

[0102] Step 3.1: Individual firefighting operations and data upload: The soldier observes the fire through a head-mounted display and uses a joystick to simulate operations such as accessing a fire extinguisher, connecting a hose, and adjusting the water gun's angle. The somatosensory vest provides temperature feedback based on the virtual distance from the flames, and the handle generates recoil feedback when operating the high-pressure water gun. The system collects the soldier's position, movement, and operation accuracy, as well as the duration of the firefighting operation, in real time, and uploads the data to the emergency command system via a secure data channel.

[0103] Step 3.2: Firefighting vehicle driving and firefighting linkage: The driver completes vehicle starting, acceleration, steering, and obstacle avoidance operations through a simulated cockpit. The multi-screen display module updates road conditions and vehicle instrument panel data in real time. Upon arrival at the scene, the firefighting operation simulation device adjusts the water cannon range and angle, coordinating with the individual soldier's position to carry out firefighting. The data acquisition and control module transmits the vehicle's driving trajectory, parking position accuracy, and water cannon spray parameters to the emergency command system in real time, and simultaneously shares them with the individual soldier's system.

[0104] Step 3.3, Real-time monitoring and dispatch: The emergency command platform processes massive amounts of real-time data through a multi-host configuration module, and dynamically displays on the command screen the movement trajectory of individual soldiers, the effectiveness of fire-fighting operations, the location and status of vehicles, and the curve of fire changes in each area. Command personnel can use this to promptly grasp the rescue dynamics and make flexible decisions and adjustments to ensure the smooth progress of the rescue operation and ultimately respond to sudden aircraft fire incidents.

[0105] Preferably, in step 4, specifically:

[0106] Step 4.1. Dynamic Assessment of Collaboration Status: Each subsystem integrates an intelligent monitoring module that analyzes operations in real time based on a preset library, identifying violations, inefficient, or high-risk behaviors. It then provides trainees with instant audible, visual, and vibration warnings or guidance via terminal devices. The emergency command platform aggregates multi-source data in real time to calculate and visualize key collaborative effectiveness indicators.

[0107] Step 4.2: Generate a multi-dimensional training report: The emergency command system automatically aggregates data from the three systems to generate a collaborative training report. The role performance dimension is evaluated through individual firefighting efficiency scores, driver operational standardization scores, and command decision rationality scores. The collaborative effectiveness dimension is evaluated through cross-role task response time, resource supply and demand matching, and the success rate of collaborative handling of dangerous situations, as well as the identification of collaborative weaknesses.

[0108] Step 4.3: Review, Analysis, and Optimization: All trainees use the emergency command platform's immersive, multi-perspective review mode to simultaneously view the entire training process and analyze collaboration issues based on data reports. Optimization plans are developed for these issues and updated to the emergency command system's contingency plan library to provide a basis for improvement in subsequent training.

The multi-screen display module updates road conditions and vehicle instrument panel data in real time. Upon arrival at the scene, the firefighting operation simulation device adjusts the water cannon range and angle, coordinating with the individual soldier's position to carry out firefighting. The data acquisition and control module transmits the vehicle's driving trajectory, parking position accuracy, and water cannon spray parameters to the emergency command system in real time, and simultaneously shares them with the individual soldier's system. Step 3.3, Real-time monitoring and dispatch: The emergency command platform processes massive amounts of real-time data through a multi-host configuration module, and dynamically displays on the command screen the movement trajectory of individual soldiers, the effectiveness of fire-fighting operations, the location and status of vehicles, and the curve of fire changes in each area. Command personnel can use this to promptly grasp the rescue dynamics and make flexible decisions and adjustments to ensure the smooth progress of the rescue operation and ultimately respond to sudden aircraft fire incidents.

10. The training method according to claim 6, characterized in that The specific method of step 4 is: Step 4.

1. Dynamic Assessment of Collaborative Status: Each subsystem integrates an intelligent monitoring module that analyzes operations in real time based on a preset library, identifying violations, inefficient, or high-risk behaviors.
