[0040] Figure 2 It is a logic block diagram of a nuclear power plant fire alarm response device based on a three-dimensional engine provided by the present invention. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0042] The present invention provides a nuclear power plant fire response method based on a three-dimensional engine. The three-dimensional model constructed by the three-dimensional engine realizes real-time visual monitoring of the internal structure of the nuclear power plant, significantly improving the efficiency and accuracy of the fire response. By integrating firefighting equipment information and monitoring multiple parameters inside the nuclear power plant in real time, once an abnormal parameter is detected, the system can automatically start the emergency plan and simulate the fire scene through the three-dimensional engine to provide intuitive evacuation paths and fire extinguishing solutions for on-site personnel. The present invention not only improves the safety management level of nuclear power plants, but also promotes the application of three-dimensional engine technology in the field of industrial safety, reducing the impact of fire accidents on personnel and equipment.

[0043] Specifically, Figure 1 As shown, the nuclear power plant fire alarm response method based on the three-dimensional engine includes the following steps:

[0044] Step S101: Acquire on-site environmental information of a nuclear power plant.

[0045] In the embodiment of the present invention, the on-site environment information may include but is not limited to: building layout, equipment location, pipeline direction, etc. The on-site environment information may be collected by various methods such as drone aerial photography, laser scanning, and CAD drawings.

[0046] Step S102: Based on the on-site environmental information, a three-dimensional engine method is used to construct a model to obtain an initial three-dimensional model of the nuclear power plant.

[0047] Through the application of three-dimensional engine technology, the visualization and automation of nuclear power plant fire alarm response has been achieved, the accuracy of fire alarm detection and the efficiency of response have been improved, and the risk of fire accidents has been effectively reduced.

[0048] Specifically, a high-precision initial 3D model is constructed based on the collected data, which can present key information such as the internal structure, equipment layout, and escape routes of the nuclear power plant in detail.

[0049] Optionally, in an embodiment of the present invention, according to the on-site environmental information, a 3D engine method is used to construct a model, and obtaining an initial 3D model of the nuclear power plant includes: according to the on-site environmental information, a combination of 3D laser scanning modeling and manual modeling is used to construct a model to obtain an initial 3D model. Specifically, by combining 3D laser scanning modeling with manual modeling, the actual structure of the nuclear power plant is restored to a high-precision 3D model, achieving the purpose of drawing a high-precision 3D model using 3D engine technology, so that intuitive navigation and decision support can be provided to rescue personnel in an emergency through a high-precision 3D model.

[0050] Among them, 3D laser scanning technology can quickly and accurately obtain 3D point cloud data of nuclear power plant sites. Through laser scanners, nuclear power plants can be scanned in all directions to obtain detailed 3D shapes and location information of buildings, equipment, pipelines, etc., and then use these scanned data to provide a solid data foundation for building high-precision 3D models. At the same time, based on CAD drawings, on-site photos and other data, 3D modeling software is used for manual modeling, which can achieve the purpose of more flexible handling of special situations while 3D laser scanning modeling can efficiently obtain a large amount of data, such as detail processing, material mapping, etc., so that the obtained 3D model is more realistic. Furthermore, in the process of building a 3D model, the use of 3D engine technology for modeling can enhance the autonomous controllability of the system. At the same time, 3D engine technology usually has high compatibility and scalability, which can meet the special needs of special industries such as nuclear power plants. The constructed high-precision 3D model can play an important role in fire response, daily operation and maintenance, employee training and other aspects. In an emergency, rescuers can intuitively understand the layout and escape routes of the nuclear power plant through the 3D model, quickly locate the fire source and dangerous areas, and formulate effective rescue plans. At the same time, the three-dimensional model can also be combined with the real-time monitoring system to achieve real-time monitoring and early warning of emergency situations such as fire.

[0051] Furthermore, in the embodiment of the present invention, after the initial three-dimensional model is constructed, in order to improve the accuracy and effect of the model, the present invention can also optimize the initial three-dimensional model. Among them, any one or more methods in the parameterized model method, double clipping method, batch drawing method and model instantiation method, ETC texture compression method, and cloud computing platform can be used to optimize the initial three-dimensional model.

[0052] In some embodiments, after the construction of the initial three-dimensional model is completed, the initial three-dimensional model is optimized using a parametric modeling method. The three-dimensional engine can use parametric modeling technology to optimize rendering efficiency and / or rendering quality. Among them, the parametric modeling method uses parameters to define the shape and properties of the model, rather than storing detailed data of each vertex, which can significantly reduce the occupation of resources, making it more efficient to render large scenes. The parametric modeling method controls the shape, size, position and other properties of the model by defining a series of parameters. These parameters can be simple numerical values ​​(such as length, width, height), etc., or more complex mathematical expressions or functions. Unlike the traditional modeling method that directly stores the detailed data of each vertex, the parametric modeling method only needs to store these parameters and the generation rules of the model, so the generated model can be made more compact.

[0053] Specifically, the optimization of the initial three-dimensional model using the parametric model method specifically includes the following steps: First, a series of necessary parameter sets are defined according to the actual structure and layout of the nuclear power plant. These parameter sets may include the height, width, location coordinates of the building, the model, size, installation location of the equipment, etc. Secondly, mathematical relationships or logical rules between these parameters are established to describe the mutual relationships and constraints between the various parts of the model. These relationships can ensure that when a certain parameter is modified, the other parts of the model can be adjusted accordingly to maintain the overall coordination and consistency. Then, the initial three-dimensional model is optimized according to the defined parameter sets and parameter relationships using the three-dimensional engine technology. This process can be real-time or dynamically generated when needed. Furthermore, after the three-dimensional model is generated, the optimization algorithm of the three-dimensional engine is used to further optimize the model, such as removing redundant data, merging similar elements, applying texture compression, etc. Finally, the optimized model is rendered and displayed to the user or used for subsequent simulation and analysis.

[0054] Since parametric models can store only control parameters and generation rules instead of detailed vertex data, the space occupied by data storage can be significantly reduced. This is especially important for processing large and complex nuclear power plant scenes. The optimized parametric model is more efficient when rendering because the rendering engine can quickly generate the model's geometric data based on the parameters without having to process a large amount of redundant data. This helps to increase rendering speed and frame rate and enhance user experience. Parametric models are highly flexible and reusable. By modifying the parameter set or parameter relationship, the shape, size and properties of the model can be easily adjusted to meet different needs and scenarios. In addition, the same parametric model can be reused by multiple projects or scenarios, which improves the utilization rate and development efficiency of the model. Parametric models are easy to maintain and update. When the structure or layout of the nuclear power plant changes, the model can be quickly updated by modifying the corresponding parameter set or parameter relationship without recreating the entire model. This greatly reduces maintenance costs and time costs.

[0055] In some embodiments, after the initial 3D model is constructed, the initial 3D model is optimized using a double clipping method. The 3D engine can use this technology to optimize rendering efficiency and / or rendering quality. The GPU and CPU are used to perform clipping calculations at the same time, and this technology is used to remove invisible objects or geometric bodies in advance, thereby reducing subsequent unnecessary rendering calculations and bandwidth consumption.

[0056] In some embodiments, after the construction of the initial three-dimensional model is completed, the initial three-dimensional model is optimized by using a batch drawing method and a model instantiation method. The three-dimensional engine can use this technology to optimize rendering efficiency and / or rendering quality. In this way, it is possible to call image data once to draw multiple graphic objects, which can reduce the communication overhead from the CPU to the GPU and improve rendering efficiency. The double clipping technology usually includes two levels of clipping, wherein the CPU-level clipping first performs preliminary clipping on the CPU before the data is sent to the GPU for rendering. This step uses the spatial structure of the scene and the position, orientation and other information of the camera to quickly determine which objects or geometric bodies are invisible from the current perspective, thereby removing these invisible parts from the rendering queue. CPU-level clipping is usually based on simple geometric judgments, such as frustum culling, which checks whether the bounding box of the object intersects with the camera's frustum. If it does not intersect, the object is considered invisible from the current perspective. GPU-level clipping After CPU-level clipping, the remaining visible objects or geometric bodies will be sent to the GPU for further rendering processing. On the GPU, more complex algorithms and hardware acceleration capabilities can be used for more sophisticated culling. For example, the parallel processing capabilities of the GPU can be used to perform visibility tests on each triangle of an object, and further eliminate triangles that are within the frustum but are actually blocked by other objects.

[0057] Furthermore, the cropping area can be dynamically adjusted according to the real-time position and orientation of the camera to ensure that only objects that are truly visible from the current perspective are rendered. This function can be achieved by continuously updating the cropping parameters in the rendering loop. For objects far away from the camera, a lower-precision model (Level of Detail, LOD) can be used for rendering to reduce the rendering burden. Double cropping can be combined with LOD technology to ensure accurate cropping even with low-precision models. In addition to frustum cropping, occlusion culling technology can also be used to further reduce the rendering burden. Occlusion culling analyzes the relative position relationship between objects in the scene to determine which objects are obscured and invisible by other objects, and then removes these objects from the rendering queue. By culling invisible objects or geometries in advance, unnecessary subsequent rendering calculations and bandwidth consumption are reduced, thereby improving rendering performance and frame rate. The load on the GPU and CPU is reduced, allowing the system to handle other tasks more efficiently, such as physical simulation, AI calculations, etc. When rendering large-scale scenes, such as the 3D model of a nuclear power plant, double cropping technology can ensure smooth operation of the scene, reduce freezes and delays, and improve user experience. Double cropping technology provides a good scalability foundation for 3D model rendering and can be easily combined with other optimization technologies to further improve rendering effects and performance.

[0058] In some embodiments, after the initial three-dimensional model is constructed, the initial three-dimensional model is optimized using a logarithmic depth method, an ETC texture compression method, or a cloud computing platform.

[0059] Specifically, in 3D model rendering, the 3D engine can use logarithmic depth technology to optimize rendering efficiency and / or rendering quality. The use of logarithmic depth technology is to solve the problem of flickering of overlapping surfaces in the model. In the traditional rendering pipeline, the depth information of the object is stored linearly, which means that as the number of objects in the scene increases, the resolution of the depth buffer also needs to increase accordingly, thereby increasing the computation and storage overhead. The depth information is logarithmically converted using the logarithmic depth technology, so that the depth value range of objects far away from the camera is larger, while the depth value range of objects close to the camera is smaller. In this way, while maintaining accuracy, the resolution of the depth buffer can be more effectively used to render distant objects, saving computing resources. In 3D model rendering, logarithmic depth technology (LDB) is an effective optimization method, especially suitable for processing large-scale scenes such as 3D models of nuclear power plants, which may contain a large number of overlapping and far-and-near objects. This technology significantly improves the utilization of the depth buffer by changing the storage method of depth information, thereby improving rendering efficiency and picture quality.

[0060] In some embodiments, the 3D engine can optimize the 3D model through ETC texture compression technology. It is understandable that the 3D engine can use this technology to optimize rendering efficiency and / or rendering quality. By compressing texture data using ETC texture compression technology, the size of image data can be greatly reduced, thereby improving storage and transmission efficiency. By using ETC texture compression technology, the size of texture data can be compressed to 4-8 times the original size. This compression technology can also play a role in real-time cropping data, and the original data can be compressed to about 32 times the size. In addition, ETC texture compression technology also supports half-floating point compression, which can reduce the data size without losing too much quality.

[0061] ETC texture compression technology is a compression format optimized for mobile graphics hardware. It is widely used in games, virtual reality (VR) and augmented reality (AR), including 3D model optimization of complex scenes such as nuclear power plants. Using ETC texture compression technology in 3D engines can significantly improve the storage, transmission and rendering efficiency of models while maintaining good image quality. The ETC family includes multiple formats such as ETC1, ETC2 and EAC (Alpha component compression of ETC2), each of which has its specific application scenarios and advantages. ETC1 is suitable for RGB data compression, while ETC2 extends support for RGBA and high dynamic range imaging (HDR). According to the specific needs of the 3D model of the nuclear power plant, the most suitable ETC format can be selected for compression to achieve the best balance between compression ratio and image quality. Before ETC compression, proper preprocessing of texture data can further improve compression efficiency and image quality. This includes color space conversion (such as conversion from sRGB to linear space), texture size optimization (such as selecting the appropriate texture size to reduce memory usage and calculation), and simplification of texture content (such as removing unnecessary details and noise). ETC texture compression technology can be combined with other 3D model optimization technologies to further improve rendering performance and image quality. For example, ETC compression can be combined with multi-level image pyramid (MIP) to reduce the texture details of distant objects and improve rendering efficiency; it can also be combined with LOD (level of detail) technology to dynamically adjust the texture resolution and complexity of the object according to its distance and importance. For very large 3D models of nuclear power plants, it may not be possible to load all texture data into memory at once. At this time, ETC texture compression technology can be combined with real-time texture streaming technology to dynamically load and unload texture data according to the position and viewing angle of the camera. This not only reduces memory usage, but also improves loading speed and rendering smoothness.

[0062] ETC texture compression technology can significantly reduce the size of texture data, thereby significantly reducing storage space requirements and transmission time. This is particularly important for application scenarios where the 3D model of a nuclear power plant needs to be deployed in the cloud or transmitted over the network. Since the texture data after ETC compression is smaller, the amount of calculation and memory usage required when loading and rendering are also reduced accordingly. This helps to increase the rendering frame rate, reduce freezes and delays, and improve the user experience. ETC texture compression technology achieves efficient compression while maintaining high image quality. By selecting the appropriate compression format and parameter settings, the data size can be reduced without losing too much quality, thereby maintaining the visual effect of the 3D model of the nuclear power plant. ETC compression technology reduces the load on the GPU and CPU when processing texture data, which helps save hardware resources. This enables better rendering effects even on hardware with lower configurations, improving the compatibility and accessibility of applications.

[0063] In some embodiments, the 3D engine renders the 3D model through a cloud computing platform. It is understandable that the 3D engine can use this technology to optimize rendering efficiency and / or rendering quality. Cloud rendering technology uses a cloud computing platform to render images, and achieves high-quality and fast rendering processing by uploading models to cloud servers and using their powerful computing power and high-speed network connections. Cloud rendering is controlled by a scheduling service to start and shut down the cloud rendering service. The front end is connected by referencing a dedicated JS library. The front end accesses the business interface of cloud rendering through JS scripts. The back end does not need to directly connect to the cloud rendering service. Through cloud rendering technology, field staff can access the 3D model directly on mobile devices without performing a lot of calculations locally. According to project requirements and the number of users, cloud rendering technology can dynamically adjust computing resources to optimize rendering performance and response speed. For large-scale 3D scenes containing a large number of details and elements, cloud rendering can be efficiently processed and displayed to ensure visual effects. The cloud rendering platform outputs image data to users, and does not transmit any model data to ensure the security and reliability of project data.

[0064] One of the core advantages of the cloud rendering platform is its ability to dynamically adjust computing resources according to the current workload. For large-scale, highly complex 3D scenes such as nuclear power plants, rendering tasks can be very arduous. Through intelligent resource scheduling algorithms, the cloud rendering platform can monitor the execution of rendering tasks in real time and automatically increase or decrease computing resources (such as the number of CPU and GPU cores) as needed to ensure the efficient completion of rendering tasks. This elastic computing resource allocation mechanism not only improves rendering efficiency, but also reduces costs, because users only pay for the computing resources actually used. Through cloud rendering technology, on-site staff can view and interact with 3D models in real time on mobile devices. This is due to the high-speed network connection and low-latency transmission capabilities of the cloud rendering platform. Users can easily access the cloud-rendered 3D scenes through browsers or dedicated applications on mobile devices, and perform operations such as rotation, zooming, and panning to obtain views from different angles and details. In addition, the cloud rendering platform also supports real-time preview, that is, users can immediately see the rendering effect during model modification, thereby speeding up design iteration and decision-making. The cloud rendering platform adopts strict security measures during data transmission and storage to ensure the security and reliability of project data. First, the platform will encrypt the uploaded model data to prevent it from being intercepted or tampered with during transmission. Secondly, the image data generated during the rendering process is only stored and transmitted in the cloud, and the original model data will not be exposed to external users. Finally, cloud rendering platforms usually have a complete permission management mechanism, and only authorized users can access specific rendering tasks and data. Cloud rendering technology has good cross-platform compatibility and supports multiple operating systems and browsers. This means that no matter what type of mobile device or computer the user is using, they can access the cloud-rendered 3D model through a standard web browser or dedicated application. This cross-platform compatibility greatly improves the flexibility and convenience of the user experience.

[0065] Cloud rendering technology uses the powerful computing power and high-speed network connection of the cloud computing platform to achieve high-quality and fast rendering processing. For large-scale 3D scenes with a lot of details and elements, cloud rendering can efficiently process and display, ensuring the authenticity and accuracy of visual effects. With cloud rendering technology, on-site workers can access 3D models without having to perform a lot of calculations locally. This reduces the requirements for local hardware performance, allowing users to smoothly view and interact with 3D scenes on mobile devices of various configurations. The cloud rendering platform adopts strict security measures during data transmission and storage to ensure the security and reliability of project data. Users do not need to worry about the risk of data leakage or loss. Cloud rendering technology provides real-time interaction and preview functions, allowing users to view and modify 3D models anytime and anywhere. This convenient access method improves user efficiency and satisfaction. At the same time, cross-platform compatibility also allows users to get a consistent experience on different devices.

[0066] Step S103: Acquire the on-site fire-fighting equipment information of the nuclear power plant.

[0067] In the embodiment of the present invention, the on-site firefighting equipment information may include, but is not limited to: information on firefighting-related materials and facilities such as temperature sensors, smoke detectors, video surveillance, and fire extinguishers and important equipment.

[0068] Step S104: Integrate the on-site firefighting equipment information into the initial three-dimensional model to obtain a composite three-dimensional model.

[0069] In the embodiment of the present invention, real-time monitoring is achieved by integrating real-time data such as temperature sensors, smoke detectors, and video surveillance inside the nuclear power plant into the initial three-dimensional model. By integrating information on fire-related materials and facilities such as fire hydrants, fire extinguishers, and important equipment in the nuclear power plant into the initial three-dimensional model, accurate location and status information of materials and facilities can be provided for fire protection. Real-time data such as various sensors (such as temperature sensors, smoke detectors), video surveillance, and fire-fighting facilities (such as fire extinguishers and fire hydrants) inside the nuclear power plant are integrated into the initial three-dimensional model. Seamless data docking can be achieved through data interfaces and protocol conversion, so that the initial three-dimensional model can reflect the on-site situation in real time. Through the integrated data, key parameters such as temperature and smoke concentration inside the nuclear power plant are monitored in real time. Once abnormal data is detected, the early warning mechanism is triggered immediately. At the same time, the abnormal data can be intelligently judged by combining algorithm analysis to distinguish false alarms from real fire alarms. Once the fire alarm is confirmed, the emergency plan is automatically started.

[0070] Step S105: Collect monitoring signals of on-site fire-fighting equipment of the nuclear power plant in real time to obtain real-time fire-fighting monitoring information.

[0071] Step S106: Determine whether a fire has occurred based on the composite three-dimensional model and real-time fire monitoring information.

[0072] Step S107: If yes, generate a visual guidance strategy based on the real-time environment information and real-time firefighting equipment information of the nuclear power plant site. If no fire alarm occurs, continue monitoring.

[0073] In an embodiment of the present invention, generating a visualization guidance strategy based on real-time environmental information and real-time fire-fighting equipment information at a nuclear power plant site includes: generating a visualization guidance strategy using a digital twin method based on real-time environmental information and real-time fire-fighting equipment information.

[0074] In an embodiment of the present invention, the digital twin method uses digital twin technology to generate a visual guidance strategy. Specifically, digital twin technology is a technology that combines physical entities or processes in the real world with their digital virtual models. This technology needs to rely on network communication technology and information modeling technology, use network communication technology to obtain basic data from various related systems, and then associate it with the information model through a set of data mapping specifications, and update the data in real time through the network to ensure the validity and reliability of the data. Through digital twin technology, the on-site fire alarm signal is linked with the three-dimensional scene, and the three-dimensional scene is used to quickly locate the fire location, view the on-site monitoring screen and related equipment information.

[0075] When constructing the digital twin model, high-precision three-dimensional modeling technology is used to restore the site environment, building structure, equipment layout, etc. of the nuclear power plant in detail. At the same time, combined with the physical engine and simulation technology, dynamic processes such as fire spread and smoke flow are simulated to make the model closer to the actual situation. This refined modeling and simulation capability provides a more realistic and reliable simulation environment for emergency response. In addition to basic site environment information and fire equipment information, the digital twin platform can also integrate data from multiple systems, such as video surveillance, environmental monitoring, and personnel positioning. Through multi-source data fusion technology, cross-validation and complementation of data are achieved to improve the comprehensiveness and accuracy of data. This helps to quickly obtain comprehensive on-site information when a fire occurs, providing strong support for decision-making. The digital twin platform has strong intelligent analysis capabilities and can automatically identify abnormal situations and potential risks based on real-time data and historical data using algorithms such as machine learning and data mining. Before a fire occurs, the platform can issue early warning signals through intelligent analysis to buy valuable time for emergency response. At the same time, after a fire occurs, the platform can quickly analyze the trend of fire spread and the scope of impact, providing a basis for formulating rescue plans. The digital twin platform provides an intuitive interactive operation interface, and users can interact with the model through touch screens, VR / AR devices, etc. When a fire occurs, users can quickly locate the fire through three-dimensional scenes, view on-site monitoring images and related equipment information. In addition, the platform can also provide a variety of emergency response plans according to user needs, and demonstrate the effects and consequences of different plans through simulation, providing an intuitive and scientific basis for decision-making.

[0076] Through digital twin technology, the on-site fire alarm signal and the three-dimensional scene are linked, so that emergency responders can quickly obtain fire information and locate the fire source. At the same time, the intelligent analysis and early warning functions provided by the platform can detect potential risks in advance and issue early warning signals, buying more time for emergency response. The digital twin platform provides comprehensive on-site information and a variety of emergency response plans for decision makers to refer to. By simulating and displaying the effects and consequences of different plans, decision makers can more intuitively understand the advantages and disadvantages of various plans and the possible impacts, so as to formulate more accurate and efficient rescue plans. Digital twin technology helps to achieve optimal allocation and efficient use of resources. During the emergency response process, the platform can dynamically adjust the resource allocation plan according to the development of the fire and the rescue needs, ensuring that key equipment and personnel can be in place in time and maximize their effectiveness. Through the display and simulation functions of the digital twin platform, employees can enhance their awareness and understanding of fire emergency response, improve their safety awareness and emergency handling capabilities. At the same time, the platform can also provide managers with comprehensive data analysis and management tools to help managers better understand the site environment, equipment conditions, and emergency response processes, thereby improving the overall management level.

[0077] Furthermore, after generating the visualization guidance strategy, it also includes: collecting various data in the fire alarm response process; and evaluating the fire alarm response system based on the various data.

[0078] Specifically, by collecting various data during the fire alarm response process and evaluating the performance and effect of the fire alarm response system based on various data analysis, existing problems or deficiencies can be discovered. For example, based on data feedback and analysis results, the composite three-dimensional model, algorithm logic, system integration and other aspects are continuously optimized to continuously improve the intelligence level of the fire alarm response system and the safety management level of the nuclear power plant.

[0079] In addition to basic data such as fire alarm signals and fire equipment status, multi-dimensional data including personnel evacuation, environmental parameter changes (such as temperature, humidity, smoke concentration), equipment failure records, etc. can also be collected. These data will provide a more comprehensive basis for subsequent performance evaluation. By adopting advanced data analysis algorithms and machine learning models, the collected data can be deeply mined and intelligently analyzed. By identifying patterns, trends and anomalies in the data, the key problems and bottlenecks in the fire alarm response process can be quickly located. The results of the analysis and evaluation are fed back to the three-dimensional model, algorithm logic, system integration and other levels in a timely manner to form a closed-loop optimization mechanism. This mechanism can ensure that problems are responded to and solved in a timely manner, while promoting the continuous improvement of the overall performance of the system. Based on data feedback and actual results, the three-dimensional model is regularly updated and optimized, the algorithm logic is adjusted to improve accuracy, and the system integration is optimized to improve collaborative efficiency. At the same time, new technologies and methods are introduced, such as AI-assisted decision-making and Internet of Things (IOT) integration, to further improve the intelligence level of the fire alarm response system. Digital twin technology and three-dimensional engines can also be used to build virtual fire emergency scenarios to provide realistic training and drill environments for staff. By simulating the real fire response process, the emergency response and collaboration capabilities of the staff can be improved. Combine virtual simulation training with actual emergency drills, and regularly organize actual combat drills. Through actual combat drills, the actual effect of the fire response system can be tested, and feedback can be collected for further optimization.

[0080] In addition, the safety risks of nuclear power plants can be regularly assessed based on historical data and real-time monitoring information. Potential safety hazards can be discovered in advance through the intelligent early warning system, providing strong support for preventing fire accidents. Combined with the actual operation of the fire alarm response system, the safety management system and emergency plan of the nuclear power plant are continuously improved. Ensure that the emergency response mechanism can be activated quickly and orderly in emergency situations such as fires to minimize casualties and property losses.

[0081] Through the digital and intelligent fire alarm response system, the rapid identification, positioning and response to fire alarm signals are realized. At the same time, through data analysis and intelligent decision-making support, the accuracy and pertinence of fire alarm response are improved. Through timely fire alarm warning, efficient emergency response and effective risk control measures, the impact of fire accidents on nuclear power plant personnel and equipment is significantly reduced. By building a closed-loop feedback and continuous optimization mechanism, strengthening personnel training and emergency drills, and improving the safety management system, the safety management level and overall operational efficiency of nuclear power plants are continuously improved. The implementation of the present invention not only improves the fire alarm response capability of nuclear power plants, but also promotes the application and development of domestic three-dimensional engine technology in the field of industrial safety. It provides experience and case support for other industries.
