[0042] See also Figure 1 The present invention provides a nuclear power plant intelligent fire response command coordination system, comprising:

[0043] A virtual subsystem, which is constructed with a nuclear power plant fire alarm information database and virtual scenes, and is used to receive fire alarm signals from the automatic fire alarm system in the nuclear power plant;

[0044] The first response module obtains the information of the fire alarm full information database, virtual scenes and fire alarm signals in the virtual subsystem, and is used by the internal personnel of the nuclear power plant to perform firefighting action response;

[0045] A second response module, which obtains information of the fire alarm full information database and the fire alarm signal in the virtual subsystem and the first response module, and is used by personnel outside the nuclear power plant to perform firefighting action response;

[0046] The first response module performs interactive feedback with the virtual subsystem and the second response module respectively.

[0047] Specifically, in an embodiment of the present invention, the virtual subsystem of the collaborative system stores information about the fire alarm of the nuclear power plant, such as fire equipment, historical fire data, and emergency plans, by constructing a fire alarm full information database. The virtual scene constructed is used to simulate the actual physical environment of the nuclear power plant, and the fire alarm signal issued by the nuclear power plant's own automatic fire alarm system is combined to provide spatial information when the fire occurs, so that the nuclear power plant personnel can obtain intuitive information for decision-making. In the first response module of the collaborative system, it can be integrated with the virtual subsystem to receive information in the virtual subsystem in real time, and provide it to the internal personnel of the nuclear power plant, such as the main control room operator, equipment technicians, etc., and can respond to the fire information by executing fire actions accordingly, and control the relevant fire risks within the limited range of the nuclear power plant. In the second response module of the collaborative system, it is also integrated with the virtual subsystem and the second response module, and the relevant fire information from the first response module and the virtual subsystem is obtained in real time, and the external personnel of the nuclear power plant, such as the fire brigade, the medical team, and the emergency service, are coordinated to perform fire action responses, ensuring the effective control of the relevant fire risks. The synchronization and effectiveness of internal and external responses of the nuclear power plant are ensured through real-time information flow with interactive feedback between coordinated subsystems and modules.

[0048] More specifically, the first response module can adjust the internal response measures according to the actual situation and pass the feedback to the second response module so that the external response can also be adjusted in time. That is to say, when a fire occurs, the collaborative system can quickly identify the source of the fire and command internal personnel to take actions (such as fire extinguishing, evacuation, etc.). The first response module monitors the fire information corresponding to the fire alarm signal in real time, for example, using various sensors in the nuclear power plant to provide intuitive data display on the visual dashboard in the main control room. Cooperate with the internal communication system to ensure efficient information flow between departments, assess the fire risk level, and adopt emergency response measures in time. Once external support is needed, the second response module of the collaborative system can quickly send a request for help to the external fire department and provide detailed information on the accident site. According to the development of the fire, it dynamically dispatches emergency resources (such as fire trucks, fire extinguishing equipment, etc.), optimizes response efficiency, and shortens response time. By combining advanced virtual technology and real-time data processing, the emergency response capability of nuclear power plants in fire incidents is improved. Through the implementation of the system, not only can the response efficiency be improved, but also the safety culture can be enhanced and potential risks can be reduced.

[0049] In this way, by adopting digital technologies such as virtual simulation, mathematical modeling, artificial intelligence, and 5G, a virtual subsystem containing a nuclear power plant fire response full information database and virtual scenes is established to realize the automation and intelligent management of the multi-level fire response process of the nuclear power plant. In the subsystems and functional modules included in the collaborative system, functional concentration is achieved, resources and information are fully shared, and the needs of fire response services at different levels are fully considered. It can provide engineering digital applications for power plants from the entire life cycle of nuclear power plant operation and maintenance, and can establish links with other operating systems of the power plant to form a more powerful nuclear power plant intelligent fire protection system.

[0050] See also Figure 2 In one embodiment, the virtual subsystem also includes constructing an association mapping between a fire alarm full information database and a virtual scene; the fire alarm full information database includes fire management information, system equipment information, fire facility information and structure information of the nuclear power plant; the virtual scene includes a plant modeling of the nuclear power plant.

[0051] Specifically, in an embodiment of the present invention, by establishing a full information database of fire alarm response in a power plant, and establishing a virtual scene of a nuclear power plant building and system, information integration and display are performed on the virtual scene. Aiming at the needs of digitalization, informatization, and intelligence of fire alarm response, the system functions include three-dimensional virtual scene, full information integration of fire alarm response, and association mapping of three-dimensional virtual scene and response information. Realize the integrated mapping of three-dimensional scene and response information: associate and map the three-dimensional virtual scene of the nuclear power plant with the full information database of fire alarm response in operation, so that the three-dimensional virtual scene becomes a quick navigation tool for response information. By interacting with the system, equipment and facilities in the three-dimensional virtual scene, relevant information will be displayed, and a three-dimensional virtual picture of the fire in the plant room will be displayed according to the address code mapping table and fire information. Associate the full information database of fire alarm with the virtual scene, realize the combination of real-time data of equipment in the database with the virtual scene, and provide instant feedback. Simulation drills can also be performed in a virtual environment to help nuclear power plant internal personnel familiar with emergency procedures. Similarly, in critical situations, the fire situation can be quickly assessed through virtual scenes, and decisions can be made based on the information in the database. In this way, the fire prevention and control capabilities of nuclear power plants can be improved, and the safety of personnel and facilities can be effectively guaranteed.

[0052] More specifically, a nuclear power fire alarm response full information integrated database is established: collect and uniformly manage the plant structure information, fire protection facility information inside and outside the plant and fire compartments, system equipment information inside and outside the plant and fire compartments, fire protection management information of the plant and fire compartments, power plant fire alarm linkage system signals and other dynamic and static information related to fire alarm response. In the fire alarm full information database, its fire protection management information may include fire protection organization structure, fire drill records, emergency plans and response processes. System equipment information may include monitoring systems such as smoke detectors, temperature sensors, etc., automatic fire extinguishing systems such as sprinkler systems, gas fire extinguishing devices, etc., as well as the operating status and maintenance records of other related equipment. Fire protection facility information may include the location of fire passages and entrances and exits, the location of fire hydrants and fire extinguishers, and the location of safety exits and evacuation signs. Structure information may include architectural structural drawings, material properties such as its flammability and fire resistance, and the functions and usage of each area in the structure. Construction of a virtual 3D fire alarm system: The plant and system are modeled using 3D modeling technology, and the model is lightweight and artistically rendered to be consistent with the real object, and the amount of data that does not exceed the normal operation of the system is borne. In the virtual scene, the plant modeling is used to create 3D modules of the buildings and facilities of the nuclear power plant for intuitive display and analysis. At the same time, environmental simulation is performed to consider various environmental factors when a fire occurs, such as smoke diffusion and high temperature effects, to simulate real scenes. Similarly, users can also perform related operations and drills in a virtual environment to provide emergency response capabilities under actual fire conditions.

[0053] It should be noted that by setting up nuclear power plant buildings and fire partitions, various sensors (such as smoke detectors and temperature sensors) are connected to the virtual subsystem through interfaces to collect fire data in real time. Combined with various sensors such as temperature, smoke, and humidity, the environmental changes of the nuclear power plant are monitored in real time. And the data fusion algorithm can comprehensively process the data of different sensors to improve the monitoring accuracy. And the fire detector signals and fire-related detector signals in the fire partition are connected to the constructed virtual scene to realize information integration and display on the virtual scene. At the same time, based on real-time monitoring data and simulation results, the system can automatically adjust internal response measures, such as mobilizing fire-fighting equipment or changing personnel allocation.

[0054] In this way, on the basis of the traditional automatic fire alarm system, combined with the actual application scenarios, with the fire Internet of Things data as the core, the fire safety status is perceived online in real time through the signals of fire alarm detectors and fire-related detectors, to ensure rapid response and handling of alarms, improve fire prevention and control capabilities, and realize the visualization, automation, intelligence and efficiency of fire safety management.

[0055] See also Figure 1In one embodiment, the first response module includes an automatic fire alarm device, a main control fire alarm response subsystem and an on-site fire alarm response subsystem. The automatic fire alarm device performs an alarm operation in parallel according to the fire alarm signal and outputs information from the fire alarm full information database to personnel outside the nuclear power plant; the main control fire alarm response subsystem determines the main control operation performed by personnel inside the nuclear power plant based on the virtual subsystem; the on-site fire alarm response subsystem determines the navigation route within the nuclear power plant based on the virtual subsystem, and provides it to personnel inside and outside the nuclear power plant.

[0056] Specifically, in an embodiment of the present invention, the automatic fire alarm device is used to monitor fire alarm signals and automatically trigger an alarm according to preset conditions. At the same time, the fire alarm information is transmitted to external personnel, including fire departments and emergency response teams in real time. It can also output relevant data in the fire alarm full information database to provide a comprehensive fire situation. In this way, it is ensured that the fire information is transmitted quickly and accurately to reduce the response time. The main control fire alarm response subsystem determines the main control operation of the internal personnel of the nuclear power plant based on the data analysis of the virtual subsystem. And formulate specific emergency response steps, including command and dispatch, resource allocation and personnel evacuation plan. Realize the integration of real-time information to ensure that the decision is based on the latest fire status and environmental conditions. Provide the visual interface required by the commander to facilitate monitoring of the on-site situation and making decisions. The local fire alarm response subsystem can use the navigation route provided by the virtual subsystem to guide the internal personnel of the nuclear power plant to evacuate or respond quickly and safely. And provide the best path for external personnel to enter the nuclear power plant to ensure safe and efficient support. By providing dynamic navigation, the route is adjusted in real time according to the development of the fire. Ensure that personnel in various areas can quickly find safe exits or emergency equipment to improve escape efficiency.

[0057] In this way, the three subsystems in the first response module work together to effectively improve the nuclear power plant's response capability to fires, ensure personnel safety and facility integrity, and form an efficient fire management mechanism through real-time data sharing and intelligent decision support.

[0058] In one embodiment, the automatic fire alarm device determines the convergence point for executing fire action response from the fire alarm information database based on the fire alarm signal, and interactively feeds back the information of the convergence point between the main control fire alarm response subsystem and the on-site fire alarm response subsystem, and between the virtual subsystem and the second response module.

[0059] Specifically, the automatic fire alarm device can automatically select the meeting point from the fire alarm response holographic database according to the input fire location, automatically prompt the location of the fire action card, automatically associate information such as factory risks and unavailability of the fire protection system, and forward it to downstream users (fire brigade, medical team, etc.) with one click. It can automatically print relevant information forms while transferring and confirming the alarm, and change the serial execution in the existing technology to parallel execution, which improves the fire alarm response speed while providing more effective and reliable information.

[0060] See also Figure 3 In one embodiment, the main control fire alarm response subsystem includes:

[0061] A data center module for digitizing the content of firefighting response performed by personnel inside and outside the nuclear power plant;

[0062] A process algorithm module determines a process model for fire alarm response based on technical specifications and fire action rules, and determines a model algorithm for executing fire action response according to the process model;

[0063] The data analysis module determines the content of the fire action response based on the digital data and the fire action rules, and verifies the results of the fire action response in the virtual subsystem.

[0064] Specifically, in the embodiment of the present invention, based on the fire alarm holographic integrated virtual system, an intelligent interactive algorithm for fire alarm response for operators in the operation main control room can be developed to build an intelligent system for fire alarm response for operators. By setting an adaptive user interface, a friendly interactive interface is provided, the display content is dynamically adjusted according to the operator's operating habits and fire conditions, and key indicators and response suggestions are displayed in real time to improve the decision-making efficiency of the operator. The interactive algorithm also assists in analyzing and verifying the operator's execution of the fire alarm response form and response procedures through information, automation and intelligent means, providing decision-making basis and technical support for the operator to make fire alarm response decisions.

[0065] More specifically, the data center module in the main control fire response subsystem digitizes the multi-level fire response process in the fire action card, quickly realizes the digitization of the multi-level fire response process, and provides a data foundation for the intelligent interactive algorithm. The multi-level structure of the fire response data center aims to digitize the multi-level fire response process in the fire action card, establish a centralized data platform, and provide a solid data foundation for the intelligent interactive algorithm. By integrating various types of fire response information, it supports efficient decision-making and real-time response.

[0066] The process algorithm module develops a mathematical model algorithm for the fire response process: establish an expert model based on the operating technical specifications (based on the operating technical specifications, identify the key factors that affect the fire response, such as the type of fire source, environmental conditions, and personnel location. Through fire experts and practitioners in related fields, collect experience and suggestions to form a preliminary model framework. The Bayesian network can also be used to establish a fire response decision model to quantify the relationship between different variables. Set a probability distribution for each node to reflect the impact of various factors on the fire response under different circumstances), establish a fire response process model based on the fire action card (procedure) (that is, put the fire action Classify and organize the various measures in the card, clarify each step of the response process and their relationship), develop a fire alarm response information push algorithm (set trigger conditions such as temperature exceeding a certain threshold, smoke concentration increasing, etc., automatically push relevant information), develop a fire alarm command and dispatch function algorithm (build a linear programming model or an integer programming model to optimize resource allocation to minimize response time and losses. Consider various constraints such as personnel arrival time, equipment availability, etc., realize dynamic scheduling capabilities based on real-time data, and adjust resource allocation strategies according to on-site conditions), which can effectively improve the efficiency and accuracy of fire alarm response and provide strong support for firefighting work.

[0067] The data analysis module develops the fire alarm response data analysis function: the data analysis principle is applied to multi-level fire alarm response data analysis, including: fire alarm related equipment status analysis (such as smoke detectors, temperature sensors, fire extinguishers, fire hydrants and other equipment status data. Real-time monitoring of equipment working status such as normal, faulty, maintenance required, etc., and record changes. Thresholds can also be set to automatically trigger alarm mechanisms, such as smoke concentration exceeding the safety value), fire accident procedure operation analysis, etc. (such as analyzing the operating steps performed in historical fire alarm responses, identifying the effectiveness of following procedures, and evaluating the response time and results of different operations. The performance of each response team can also be evaluated through key indicators such as response time and fire extinguishing success rate to find room for improvement), and push relevant instructions (such as automatically generating instructions for specific situations based on data analysis results. For example, when the system detects an equipment failure, it automatically pushes maintenance instructions. Set priorities for instructions based on the type, location and severity of the fire to ensure that high-priority instructions are quickly pushed to the relevant responsible persons). By establishing a comprehensive fire alarm response data analysis function, the efficiency and accuracy of fire alarm response can be effectively improved, ensuring that timely measures are taken to reduce fire losses. At the same time, more efficient fire alarm management can be achieved by using intelligent data analysis technology and command push mechanism.

[0068] In one embodiment, the local fire alarm response subsystem transmits the navigation route in the nuclear power plant to the mobile terminal based on the communication network of the nuclear power plant.

[0069] Specifically, the local fire alarm response subsystem can be based on the mobile communication network (4G / 5G / improved Wifi) in the nuclear power plant to develop an intelligent local fire alarm response system (for example, including mobile terminal applications for on-site personnel to provide navigation, command reception and information feedback functions; command center background for centralized data processing, command generation and monitoring of on-site conditions; and data analysis modules for real-time analysis of fire data, identification of risks and optimization of response strategies). Through mobile terminals (for example, on-site personnel upload fire scene conditions in real time through mobile terminals, such as changes in fire intensity, casualties and equipment status, etc.), navigate to suitable attack routes and retreat routes (based on on-site maps and real-time fire data, automatically calculate the best attack path and safe retreat route. Consider obstacles, smoke concentration and other risk factors to ensure route safety. Provide guidance for first-level intervention operators, second-level fire intervention team personnel, on-site rescue personnel, etc.), automatically push on-site fire alarm response instructions, prompt fire-related risks, ensure the safety of on-site personnel, and can feedback fire scene conditions and disposal information.

[0070] See also Figure 1 and Figure 4 In one embodiment, the second response module includes a fire alarm communication subsystem and a fire scene command subsystem. The fire alarm communication subsystem is used to provide communication for external personnel of the nuclear power plant when performing fire action response; the fire scene command subsystem is used to determine the content of the fire action response performed by external personnel of the nuclear power plant.

[0071] Furthermore, the fire alarm communication subsystem is constructed based on the communication network of the nuclear power plant, and an interface for the fire scene command subsystem is reserved, and audio and video transmission functions are provided.

[0072] Furthermore, the fire command subsystem provides fire command, auxiliary decision-making and real-time monitoring when executing fire response based on the communication network provided by the fire alarm communication subsystem; and executes digital plans and virtual reality drills for fire response based on the fire alarm full information database and virtual scenes provided by the virtual subsystem. The fire command subsystem interacts and feedbacks with the fire alarm communication subsystem, virtual subsystem and first response module respectively.

[0073] Specifically, in an embodiment of the present invention, the fire alarm communication subsystem is intended to provide efficient and stable communication support for personnel outside the nuclear power plant, ensuring the timely transmission and coordination of information when executing firefighting operations. It can provide clear, low-latency voice call functions to ensure instant communication between on-site commanders and responders, and can also support on-site video streaming transmission. The command center can view the fire scene situation in real time and assist in decision-making. The fire scene command subsystem is used to formulate firefighting action response strategies for personnel outside the nuclear power plant and optimize the command decision-making process. In this way, the second response module can effectively improve the communication efficiency and decision-making ability of personnel outside the nuclear power plant in firefighting operations through the coordinated work of the fire alarm communication subsystem and the fire scene command subsystem, thereby enhancing the overall fire response effect and safety.

[0074] More specifically, compared with the traditional firefighting in nuclear power plants, the existing fire emergency communication methods mainly include the intercom system between firefighters and fire command vehicles, fire-dedicated telephone systems, administrative telephone systems, internal intercom telephone systems, wired broadcasting systems, wireless communication systems, etc. In view of the shortcomings of the current fire emergency communication, the intercom system between firefighters and fire commanders may not be able to communicate due to the shielding of the building structure, and there is a lack of reliable video transmission means, so the fire commander cannot fully grasp the current situation of fire information. By designing a nuclear power plant fire communication system (i.e., fire alarm communication subsystem) with high reliability and flexible networking with 5G communication function. High-definition video and sound information of the fire scene can be flexibly uploaded to the on-site command system (command platform or command vehicle), and the command system (command platform or vehicle) can also directly issue orders to fire rescue personnel at the fire scene. The design plan may include: self-organized wireless communication network; connection with the plant wireless communication system (4G / 5G / WiFi); retention of wired communication means (backup means); reservation of interfaces with the emergency command system; audio and video transmission functions. In the fire alarm communication subsystem, it mainly includes handheld terminals, control balls, relay equipment and fire scene communication devices. Communication methods include 4G / 5G network, wireless WiFi, and ad hoc network / wired.

[0075] The fire command subsystem uses high-tech means such as geographic information technology, graphics technology, communication technology, Internet of Things technology and database technology to realize the intelligentization, informatization, process and standardization of nuclear power plant emergency rescue. It can realize on-site emergency rescue command and dispatch work, complete rescue quickly and orderly, and improve the response speed of fire emergency rescue; through the audio and video output from the scene, remote visualization and interactive command between the command point and the scene can be realized, and the status of the on-site combatants can be displayed in the command interface; the auxiliary decision-making module in the system uses effective technical means such as expert resources and big data model calculations to conduct risk analysis, fire extinguishing tactics selection, fire extinguishing application calculations, combat force deployment, and attack / retreat route planning for fires. Provide auxiliary decision-making; the system provides digital plan management and application functions.

[0076] It should be noted that the specific functions of the fire command subsystem include fire command (combat deployment, combat command, linkage plan, experience summary and post-accident investigation through the system). Decision support (risk analysis setting, building structure and available fire fighting facilities setting, combat force deployment setting, fire fighting application calculation expansion, fire fighting tactics method formulation). Real-time monitoring (personnel positioning, personnel status monitoring, fire scene environment monitoring, on-site video sharing). Digital plan (plan preparation, review, familiarization, drill, application and plan information management). Three-dimensional VR drill (drill, team training, assessment and evaluation). Communication / storage (voice communication, frequency division display / data transmission, information storage). Information push (real-time alarm, message terminal push). It is also possible to regularly organize fire drills with the participation of all employees and conduct evaluations in combination with system data to improve overall safety awareness and emergency response capabilities. In addition, virtual scenes can be used for simulation training and drills to improve the emergency response capabilities of nuclear power plant employees.
