[0002] Traditional training for emergency response to hazardous gas leaks relies primarily on theoretical explanations, 2D animation demonstrations, or 3D desktop exercises. While these methods offer some teaching value, they struggle to realistically reproduce complex 3D leak scenarios and their dynamic evolution, making them difficult to provide rescuers with an immersive experience.

[0003] Furthermore, traditional drills often rely on screen presentations and lack comprehensive multi-sensory feedback, such as visual, auditory, and tactile feedback. This makes it difficult for emergency responders to accurately perceive the spatial layout and response effectiveness of a leak scenario, thus impacting training quality and improving practical skills. While field drills are closer to actual combat, they typically require significant human and material resources, are costly, and carry the risk of secondary accidents during operation.

[0004] To solve the above problems, there is an urgent need to provide a simulation solution that can render complex leakage scenarios in real time in a virtual reality environment, support multi-dimensional interactive operations, and dynamically feedback emergency response results, so as to improve the emergency decision-making and response capabilities of emergency rescue personnel.

[0040] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] Figure 1 This is a flowchart of a hazardous gas leakage treatment method provided by an embodiment of the present invention. This embodiment can be applied to simulated emergency drills for hazardous gas leakage treatment. The method can be executed by a hazardous gas leakage treatment device, which can be implemented in the form of hardware and / or software and can be configured in a computer device. Figure 1 As shown, the method specifically includes the following steps:

[0043] S110: Determine gas source properties, ambient wind direction, lighting information, pipeline material, pressure information, and a three-dimensional model corresponding to the gas leakage scenario.

[0044] The gas source attribute may be an attribute of the gas source in the gas leak scenario, for example, the gas source attribute may be the type of gas source, such as carbon monoxide. The ambient wind direction may be the wind direction in the gas leak scenario, for example, northwest wind. Preferably, the wind speed may also be determined, for example, a wind speed of 4 m / s.

[0045] Lighting information can be used to describe the lighting in the gas leak scene, such as the type, position, intensity, and color of the light source. Pipeline material information can be the physical properties of the pipe surface in the gas leak scene, such as the surface texture. Pressure information can be pipeline pressure, etc.

[0046] A 3D model can be a mathematical model that represents the 3D structure of each object in a gas leak scene. A gas leak scene can contain people, pipelines, buildings, leaking hazardous gases, rescue equipment, and so on. Therefore, a 3D model should at least include 3D models of people, 3D models of devices, 3D models of buildings, gas leak effects, and 3D models of rescue tools.

[0047] For example, 3D device models and 3D building models are used to simulate static or dynamic objects in a scene, such as buildings, pipes, and valves. Gas leak effects can be used to simulate the visual effects of a gas leak, such as smoke, airflow, and color changes. 3D rescue tool models are used to simulate rescue equipment for gas leaks, such as gas masks, gas monitors, and fire extinguishers. Therefore, to realistically simulate a gas leak scenario, it is necessary to determine the gas source properties, ambient wind direction, lighting information, pipe material, pressure information, and 3D models corresponding to the gas leak scenario.

[0048] S120 , according to the gas source properties, ambient wind direction, lighting information, pipeline material, pressure information and the three-dimensional model, a rendering engine is used for real-time rendering to obtain a target rendering scene corresponding to the gas leakage scene.

[0049] Among them, the rendering engine can dynamically and in real time render the three-dimensional image on the screen of the virtual reality device based on the above-mentioned gas source properties, ambient wind direction, lighting information, pipeline material, pressure information and three-dimensional model. The target rendering scene refers to the rendered three-dimensional image corresponding to the gas leakage scene.

[0050] Specifically, the gas source properties, ambient wind direction, lighting information, pipeline material, pressure information and three-dimensional model are input into the rendering engine. The engine calculates the color and lighting effects of each pixel in real time based on physical rules, such as ray tracing and material shading algorithms, and finally generates a dynamic and realistic target rendering scene.

[0051] S130: Displaying a target rendering scene based on the virtual reality device, and in response to a target operation on the virtual reality device, performing an emergency handling operation in the target rendering scene based on the target operation.

[0052] The virtual reality device includes a headset, controller, etc.; target operations refer to user interactions with the virtual reality device, such as operations performed on the controller. Emergency response operations can be understood as a series of actions a user performs on hazardous gas, such as detecting leaks, closing valves, or setting up warning posts. This embodiment does not limit the specific response operations.

[0053] Specifically, a target rendered scene is displayed through a virtual reality device, immersing the user in the scene and giving them a sense of being there. The user then interacts with the scene through gestures or movements, performing hazardous gas leak response operations. This allows users to immerse themselves in emergency response to hazardous gas leaks from a first-person perspective, enhancing the emergency response capabilities of emergency rescue teams.

[0054] In some embodiments, after executing the emergency response operation, the emergency response operation can also be evaluated for accuracy and operation sequence to obtain an initial evaluation result, and the execution time of the emergency response operation can be determined; based on the initial evaluation result and the execution time, the emergency response operation is evaluated to obtain a target scoring result, and optimization suggestions corresponding to the emergency response operation are generated.

[0055] Among them, emergency response operations include equipment selection operations and detection equipment use operations; the initial assessment results are obtained after a preliminary assessment of the accuracy and operation sequence of emergency response operations.

[0056] Specifically, a standardized operating procedure comparison mechanism can be incorporated to evaluate user operations to improve the relevance and scientific nature of training. For example, this mechanism can be used to record user actions such as leak detection, protective equipment use, and warning zone setting, and assess their correctness. For example, the accuracy of leak location and equipment usage can be checked, and the coverage of the warning zone within the affected area can be analyzed to ensure scientific and appropriate response.

[0057] Furthermore, user behavior directly impacts the final assessment results. For example, in a specific emergency scenario, once a user completes the critical operation of closing a valve, a detection mechanism is immediately activated to assess in real time whether the spread of hazardous gases is being effectively controlled. This assessment is then incorporated into the overall scoring system.

[0058] At the same time, time efficiency, as a core dimension in the evaluation system, plays a crucial role in the scoring results. The time it takes users to complete various tasks is recorded and judged based on preset time thresholds. If the task execution time exceeds the threshold, points will be automatically deducted. This encourages users to complete tasks more efficiently and improves the overall speed of emergency response.

[0059] After completing the entire assessment process, a comprehensive and detailed scoring report is generated. This report not only includes the user's overall score but also details individual scores for each dimension, such as operational accuracy and time efficiency, allowing users to clearly understand their performance in each dimension. Furthermore, the report addresses shortcomings and provides specific improvement suggestions to help users continuously improve their emergency response capabilities and better prepare for future emergency response efforts.

[0060] For example, when a user needs to conduct a simulated emergency drill, they can wear a virtual reality device and then select a target rendering scene from multiple simulated scenes displayed in the virtual reality scene. After selection, the virtual reality scene can display the following interface information:

[0061] Team: Team 1; Scene: Scene 1; Wind direction: Northwest; Gas: Carbon monoxide; Wind speed: 4m / s; Leakage device: Sulfur recovery.

[0062] Furthermore, a protective equipment selection interface is displayed, showing various protective equipment such as negative air respirators, filter respirators, positive pressure air respirators, and long-tube mobile air supply sources. The user can choose to wear one of these. A protective clothing selection interface is also displayed, allowing the user to select a type of protective clothing to wear, such as a level 1 airtight suit.

[0063] Furthermore, the user selects a detection device and operates the device, for example, turns on the gas detection instrument, wears protective equipment, enters scene 1, sets up warning posts in scene 1 and confirms the leakage point according to the alarm of the gas detector.

[0064] After executing the above process, you can choose to end it. This embodiment can evaluate the accuracy and operation sequence of the above equipment selection operation and detection device use operation, and at the same time obtain the scoring results based on the execution time of each operation, and generate corresponding optimization suggestions.

[0065] The technical solution of the embodiment of the present invention determines the gas source properties, ambient wind direction, lighting information, pipeline material, pressure information, and three-dimensional model corresponding to the gas leakage scenario; based on the above-determined content, uses a rendering engine to render in real time to obtain a target rendering scene corresponding to the gas leakage scenario; displays the target rendering scene based on a virtual reality device, and responds to target operations on the virtual reality device and performs emergency response operations in the target rendering scene based on the target operations. This technical solution solves the problems of existing hazardous gas leak treatment simulation methods being ineffective and costly in terms of manpower and material resources. It enables simulated emergency drills for hazardous gas leak treatment in a virtual reality scenario, improving the emergency response capabilities of emergency rescue personnel to hazardous gas leaks.

[0066] Figure 2 This is a flow chart of another hazardous gas leakage treatment method provided in an embodiment of the present invention. Based on the above embodiment, this embodiment can be further improved to address the following problems.

[0067] The applicant found that the Monte Carlo method can be used to simulate gas diffusion in gas leakage scenarios. Although it can achieve dynamic visualization through random walks of particles, the Monte Carlo method may not have sufficient simulation accuracy for complex fluid mechanics (such as turbulence and terrain occlusion). For example, actual hazardous gas leakage is affected by many factors such as wind direction, temperature and humidity, and equipment surface material, while the Monte Carlo model simplifies these physical parameters, resulting in deviations between the virtual scene and the actual leakage dynamics. Secondly, current research is limited to fixed leakage source types (such as storage tanks) and standardized environments (such as factory layouts), and lacks variable leakage scenarios. In addition, the real-time rendering of the Monte Carlo model relies on high-performance equipment, which limits its popularity in ordinary terminals (such as lightweight virtual reality headsets).

[0068] like Figure 2 As shown, the method specifically includes the following steps:

[0069] S210: Determine gas source properties, ambient wind direction, lighting information, pipe material, and pressure information corresponding to the gas leakage scenario.

[0070] S220: Execute a preset acquisition method based on the image and point cloud acquisition device to obtain visual data of each device and building in the gas leakage scene.

[0071] Among them, the preset collection methods include one or more of oblique photography, point cloud scanning and 360° panoramic photography, and each device refers to various devices in the gas leakage scene, such as pipelines.

[0072] Specifically, oblique photography can be used for large-scale terrain and architectural modeling. To accurately model complex facilities like storage tanks and pipelines, geometric structure data is acquired through point cloud scanning. 360° panoramic photography is used for texture mapping and material creation, ensuring high realism and detailed representation of 3D models.

[0073] S230: Perform modeling operations based on the visual data to obtain a three-dimensional device model of each device and a three-dimensional building model of each building.

[0074] Here, each device refers to the device in the hazardous gas leakage scenario, such as pipelines and storage tanks.

[0075] Specifically, the acquired visual data is input into a three-dimensional modeling software, and a three-dimensional device model of each device and a three-dimensional building model of each building are constructed by the three-dimensional modeling software.

[0076] It should also be noted that some visual data can be collected in advance to construct 3D device models for each device and 3D building models for each building, which are then stored in a model library. During the application phase, the 3D device models and 3D building models corresponding to the target devices and buildings in the gas leakage scenario can be directly retrieved from the model library. In other words, the 3D device models and 3D building models can be reused, allowing for the flexible construction of different gas leakage scenarios.

[0077] For example, when the leakage source type of scenario A is a tank leak, the 3D device model of the tank can be retrieved from the model library. When the leakage source type of scenario B is a pipeline leak, the 3D device model of the pipeline can be retrieved from the model library.

[0078] In some embodiments, modeling operations are performed based on visual data to obtain a three-dimensional device model of each device and a three-dimensional building model of each building, including: when the device or building is a close-up object in a gas leakage scene, establishing a high-precision model corresponding to the device or building; when the device or building is a distant object in a gas leakage scene, establishing a low-polygon model corresponding to the device or building.

[0079] Specifically, a hierarchical strategy is adopted for the 3D modeling operations of gas leak scenarios to optimize performance and realism: for close-range objects that need to be presented in the scene, such as leakage points, firefighting equipment, protective clothing and other interactive objects, high-precision models can be built based on visual data, and detailed carving can be performed using 3D software. Physically Based Rendering (PBR) technology is combined to simulate material properties such as metal reflection, protective clothing texture, and fire truck gloss to ensure immersive close-range interactions.

[0080] For distant objects in the scene, such as background buildings and vegetation, model face reduction is used to reduce computational overhead while ensuring visual continuity. Optimally, model accuracy requirements are clarified through an L1-L5 hierarchical design, with high-precision L1-L3 models serving close-up interactions and key objects, and low-precision L4-L5 models for distant backgrounds. This next-generation modeling hierarchical approach ensures scene realism while balancing rendering efficiency.

[0081] In existing technologies, real-time rendering of Monte Carlo models relies on high-performance equipment, limiting their adoption on standard devices, such as lightweight virtual reality headsets. Embodiments of the present invention utilize virtualized geometry technology to automatically optimize high-precision models (such as tanks and pipelines) into lightweight meshes, reducing GPU rendering load. They also employ multi-level-of-detail (LOD) rendering, using high-precision models for near scenes and low-polygon models for distant scenes, reducing video memory usage. This addresses the existing reliance on high-performance equipment and reduces GPU requirements for terminal devices.

[0082] S240 , according to the gas source properties, ambient wind direction, lighting information, pipeline material, pressure information and the three-dimensional model, a rendering engine is used for real-time rendering to obtain a target rendering scene corresponding to the gas leakage scene.

[0083] When rendering based on gas source properties, ambient wind direction, lighting information, pipeline material, pressure information, and 3D models, a dynamic lighting system can be integrated to simulate realistic light and shadow changes based on lighting time information such as sunrise, noon, and sunset, providing the visual effect of day and night. Furthermore, the rendering engine integrates a material information library, such as pipeline material, metal reflection, protective clothing texture, and gas transparency, to achieve realistic rendering effects for different materials under different lighting conditions, enhancing the realism of the scene.

[0084] In some optional embodiments, the target rendering scene may be dynamically changed based on the target parameter input operation in response to the target parameter input operation on the interactive interface of the virtual reality device.

[0085] The target parameters include at least one of gas type, leakage pressure, ambient temperature and humidity, diffusion coefficient and concentration threshold.

[0086] It is understandable that the current gas leakage scenario simulation technology has significant limitations. It mainly focuses on fixed leakage sources (such as storage tanks) and standardized environments (such as preset factory layouts). It is difficult to cover multiple leakage scenarios and complex environmental conditions, resulting in simulation results being out of touch with actual needs.

[0087] To solve the above problems, this embodiment supports users to customize target parameters such as leakage parameters (such as gas type, leakage pressure, aperture), and environmental variables (such as temperature and humidity, wind speed, terrain) through the virtual reality device handle and graphical interface. For example, diffusion coefficient, concentration threshold, etc. Then, dynamically calculate and generate a visualization scene including gas diffusion, concentration distribution, and toxicity effects, that is, dynamically change the target rendering scene. This technical solution covers the setting of multiple parameters, supports the simulation of multi-source leakage composite scenarios, achieves comprehensive coverage and dynamic customization of scenarios, significantly improves the flexibility and authenticity of the simulation, and provides technical support for emergency management and safety training.

[0088] In some embodiments, the gas leakage special effect is dynamically changed based on a preset algorithm; wherein the preset algorithm includes at least one of a diffusion algorithm, a wind direction and speed algorithm, a pipeline pressure, a leakage point distribution algorithm, and a gas leakage algorithm.

[0089] Among them, the gas leakage special effects can be visual effects such as smoke, concentration distribution, diffusion range, etc.

[0090] Specifically, the gas leak effect is not static; it is dynamically generated in real time using a pre-set algorithm. The diffusion algorithm simulates how a leaked gas spreads into the surrounding environment, generating dynamic smoke diffusion range and concentration gradients based on this algorithm.

[0091] The wind direction and speed algorithm simulates the effects of wind direction and speed on gas diffusion. This algorithm incorporates real-time meteorological data, such as wind speed and direction, to drive changes in gas diffusion direction and velocity. Consequently, the gas diffusion direction changes with wind direction, and the concentration distribution adjusts in real time due to changes in wind speed. Pipeline pressure can also be taken into account, as it affects the leakage flow rate.

[0092] The leak point distribution algorithm can simulate where gas leaks are coming from. For example, it dynamically generates the location and rate of leaks based on the equipment structure (such as storage tanks and pipelines) and pressure distribution. Multiple leaks can occur in different locations, and the leak rate at each point may be different. The gas leak algorithm can simulate the state of gas leaks, such as leak rate and injection direction. This algorithm calculates the gas leakage and diffusion process in real time, and the corresponding special effects will change dynamically, thereby dynamically changing the target rendering scene.

[0093] It should also be noted that while existing Monte Carlo simulations of gas diffusion can achieve dynamic visualization through random particle walks, the Monte Carlo method may not accurately simulate complex fluid dynamics (such as turbulence and terrain obstruction). For example, actual hazardous gas leaks are affected by multiple factors, including wind direction, temperature and humidity, and equipment surface material. Monte Carlo models simplify these physical parameters, resulting in deviations between the virtual scene and the actual leak dynamics.

[0094] The technical solution of the present invention can develop core algorithms and real-time environmental parameter feedback, obtain field sensor data (such as anemometers, temperature and humidity sensors) in real time through external APIs, dynamically correct the input parameters of the diffusion model, reduce the cumulative error of the static model, and significantly improve the accuracy of simulation.

[0095] S250: Display a target rendering scene based on the virtual reality device, and in response to a target operation on the virtual reality device, perform an emergency handling operation in the target rendering scene based on the target operation.

[0096] This technical solution, through dynamic simulation and immersive interactive technology, creates a highly realistic factory leakage scenario. Using algorithms such as gas leak point distribution, it accurately simulates the entire process of gas diffusion and emergency response. It integrates key processes such as protective equipment selection, gas detection, and warning zone demarcation, enabling real-time recording and intelligent scoring of user operations, forming a scientific evaluation and feedback mechanism.
