[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] Reference Figure 1 、 Figure 2 As shown, a preferred embodiment of the present invention is provided.

[0025] In a first aspect, the present invention provides a method for applying comprehensive building element information, comprising:

[0026] S1: collecting building information of a target building to obtain the building information of the target building, and constructing a building information model for providing digital feedback of the target building according to the building information;

[0027] S2: Collecting data corresponding to the target building based on a number of pre-planned building elements to obtain element information corresponding to each of the building elements of the target building; wherein the building elements include fire escape routes, evacuation routes, building structure, key parts, key areas, firefighting forces, rescue equipment, and command and deployment;

[0028] S3: performing element labeling processing on the building information model according to the element information of each building element corresponding to the target building, so as to obtain an element building model of the target building;

[0029] S4: monitoring the target building in real time by using a sensor group and AR equipment preset inside the target building to obtain real-time monitoring information of the target building;

[0030] S5: Substituting the real-time monitoring information into the element building model to obtain a real-time monitoring model of the target building;

[0031] S6: Analyze the target building according to the real-time monitoring model to obtain the actual feature distribution of the elements and the building safety feature distribution of the target building; wherein, the actual feature distribution of the elements is used to describe the real-time status of the building elements at each specific location of the target building, so that rescue personnel can have a detailed understanding of the building disaster situation of the target building, and the building safety feature distribution is used to evaluate the safety status of each specific location of the target building, so that the target building can take preventive measures.

[0032] Specifically, in step S1 of the embodiment provided by the present invention, an on-site survey of the target building is conducted to collect basic information of the building, including the building's structure, design drawings, floor layout, installation locations of pipes and equipment, etc. The survey can use traditional measurement tools or modern technologies such as laser scanning, drones, ground detection radar and other equipment. The collected data includes but is not limited to: the building's geometric shape, building materials, equipment, pipes, floor distribution, fire protection facilities, evacuation routes, structural nodes, etc.

[0033] More specifically, laser scanners (LiDAR) or ground-based 3D scanning technology are used to perform high-precision 3D measurements of building structures. These devices can efficiently capture the 3D geometric data of buildings and generate detailed digital models of them. At the same time, drone aerial photography and stereo imaging technology are combined to capture details of the exterior and interior of buildings, especially in high places or complex areas that are difficult to access. Various types of data obtained through laser scanning, drone photography, sensor collection, etc. will be integrated. In addition, the collected building information must be compared and proofread with existing building blueprints, structural drawings, equipment layouts, etc. to ensure the accuracy and consistency of the information.

[0034] More specifically, professional BIM software (such as Revit, Navisworks, etc.) is used to model the collected data. The building information model is not just a geometric model, but should also include detailed information such as the building's physical properties, spatial relationships, structural characteristics, facilities and equipment. In this process, the collected two-dimensional plan and three-dimensional spatial data are combined to generate a fully digital building model including walls, doors and windows, columns, pipes, electrical lines, air-conditioning systems, etc. The model will be specific to each floor, each room, and each building element, and parametric modeling will be used to make the building information model (BIM) operational and editable.

[0035] More specifically, if sensors (such as temperature and humidity sensors, smoke detectors, pressure sensors, etc.) have been deployed in the target building, the data of these sensors will be embedded in the BIM model to form a dynamic digital building model. This will not only display the static information of the building, but also combine real-time data to feedback the real-time status of the building (such as temperature, humidity, equipment operating status, etc.). Based on the BIM model, a digital feedback function is designed to allow the building's operating status, equipment status, environmental conditions, etc. to be fed back to the model in real time. Through the real-time monitoring data of the sensors, the dynamic status of the building (such as temperature and humidity in the building, structural health, status of fire-fighting equipment, etc.) is mapped to the building information model.

[0036] Specifically, in step S2 of the embodiment provided by the present invention, the building elements involved are pre-planned, including: fire escape passages: fire escape passages, fire extinguishers, and the location of fire hydrants in the building; evacuation passages: passages, stairs, emergency doors, etc. used for personnel evacuation; building structure: the building's frame structure, supporting columns, walls, floor layout, etc.; key parts: including key facilities and areas such as electrical equipment rooms, main water pipelines, and substations; key areas: such as flammable and explosive areas, high-risk areas, underground parking lots, etc.; firefighting forces: firefighting equipment in the building, automatic sprinkler fire extinguishing systems, smoke detectors, fire pumps, etc.; rescue equipment: rescue facilities inside and outside the building, such as fire extinguishers, life ladders, first aid equipment, escape ropes, etc.; command and deployment: emergency command centers, emergency communication facilities, and command and deployment locations inside and outside the building.

[0037] More specifically, through on-site surveys and measurements, accurate data collection is carried out on various relevant elements of the target building based on pre-planned building elements. Modern technical means such as laser scanning (LiDAR), drone photography, 3D modeling, sensor equipment, video surveillance, etc. are used to collect data. Laser scanners or drones are used to accurately scan the passage layout, doors and windows, stairs, and floor layout inside the building to confirm the width, height, passability and evacuation signs of the passage. Detailed structural data of the building is obtained through structural analysis and measuring instruments, including support points, beam and column layout, wall thickness, etc. Special measurements are carried out on key facilities such as electrical equipment rooms, machine rooms, and gas pipelines, and their spatial location, dimensions, related equipment, etc. are marked. The location and working status of all fire-fighting facilities are collected, including distribution maps of facilities such as fire extinguishers, fire hydrants, fire extinguishing systems, smoke detectors, and automatic sprinkler systems. The locations of command centers, emergency communication systems, monitoring centers, and other facilities inside and outside the building are located.

[0038] More specifically, all collected building element data will be organized and integrated through BIM (Building Information Modeling) technology to generate a detailed building information model. Through the BIM system, each element (such as fire escape routes, evacuation routes, building structures, etc.) will be converted into a digital three-dimensional model. Each element information has detailed parametric properties in the BIM model, such as the width, height, and traffic capacity of the fire escape; each exit of the evacuation route and the maximum number of people that can be evacuated in the route, etc. Relevant information of all key parts and key areas will be embedded in the BIM model so that it can be accurately obtained when a disaster occurs.

[0039] More specifically, the sensor data inside the building (such as temperature, humidity, smoke sensors, etc.) is integrated into the BIM model to track the status of each element in the building in real time. Through real-time data collection and feedback, the status of each element in the model is dynamically updated. For example, the working status of fire-fighting equipment, whether the evacuation routes are unobstructed, and whether there are safety hazards in key areas can be monitored in real time. Real-time feedback is provided to emergency response personnel in the building to ensure that they can understand the specific situation when a disaster occurs in a timely manner and optimize rescue routes and resource allocation.

[0040] Specifically, in step S3 of the embodiment provided by the present invention, the acquired element information corresponding to each building element of the target building is respectively substituted into the building information model, and the specific locations of the building information model are marked with corresponding building elements to obtain the element building model of the target building.

[0041] More specifically, in the element building model, the status information of each building element corresponding to the specific location of the building information model is marked. That is, the element building model is used to digitally express the specific status distribution of eight building elements, including fire passages, evacuation passages, building structures, key parts, key areas, firefighting forces, rescue equipment, and command and deployment. Then, through the analysis of the element building model, the specific status of the target building can be obtained.

[0042] More specifically, by analyzing the specific distribution of various building elements of the target building, the safety performance of the target building can be obtained in detail, so as to carry out safety inspection and maintenance work on the target building.

[0043] Specifically, in step S4 of the embodiment provided by the present invention, various sensors are preset in key areas of the building, such as temperature and humidity sensors, smoke detectors, fire alarms, video surveillance cameras, CO2 concentration sensors, pressure sensors, access control sensors, motion detection sensors, etc., and various sensors need to be arranged in different locations according to their functions. For example: fire equipment area: smoke detectors, temperature sensors, fire alarms, etc. are arranged; electrical equipment room or machine room: temperature and humidity sensors, vibration sensors, etc. are arranged; evacuation passages and public areas: motion sensors, cameras, etc. are arranged to monitor the evacuation of personnel in real time; environmental monitoring: such as CO2 concentration and air quality monitoring, to monitor the health of the air in the building; when arranging sensors, it is necessary to ensure that all important areas in the building are covered and that data can be collected in real time and accurately.

[0044] More specifically, various sensors transmit real-time monitoring data to a central control system or cloud platform via wireless or wired networks (such as Wi-Fi, LoRa, and 5G). The data collected by the sensors includes temperature, humidity, motion status, gas concentration, power consumption, and device status. All data should be processed and analyzed in real time. Edge computing technology can be used to perform preliminary processing near the data collection point to reduce latency and improve data processing efficiency. For example, edge computing nodes can be used near the sensor group to perform preliminary filtering, analysis, and preprocessing of the data.

[0045] More specifically, AR devices are installed inside buildings, typically terminals such as AR glasses, AR tablets, or mobile phones. The AR devices need to connect to the sensor data system in real time to display real-time building monitoring information. The AR devices use augmented reality technology to overlay sensor data onto the user's field of view. For example, data such as temperature, humidity, air quality, and CO2 concentration within the building are overlaid on the AR device's display screen. The operating status of the device (such as temperature, power consumption, and maintenance status) is overlaid on the AR view in front of the device. When a sensor triggers an alarm, the AR device displays alarm information and emergency exit instructions.

[0046] More specifically, through motion sensors, AR devices can display the distribution of people in the building in real time, especially showing the evacuation routes and locations of people in emergency situations. AR devices provide real-time feedback, allowing staff or managers to directly see key data and information on site, assisting them in making timely decisions.

[0047] More specifically, a central monitoring platform needs to be built to integrate sensor data and AR device information. This platform typically has the following functions: It displays data collected by each sensor in real time, presenting it through charts, maps, and warning messages; it monitors the operating status of each device and area within the building in real time, promptly detecting equipment failures or anomalies; and when sensor data exceeds preset thresholds, the system issues an alarm and notifies relevant personnel via AR devices, mobile phones, or other terminals for processing. The platform must be able to support multi-user collaboration, allowing building managers, security personnel, and emergency response teams to view relevant data and alarm information through the platform.

[0048] More specifically, when sensors detect an anomaly (such as fire, abnormal movement of people, poor air quality, etc.), the system automatically pushes an alarm to the AR devices and other terminal devices of all relevant personnel. On the AR devices, the alarm information and emergency evacuation channels of the affected areas are displayed in real time, helping the emergency response team to quickly formulate response measures. Through the building information displayed by the AR devices, the team can view the building's floor plan, equipment location, channel status, emergency exits and other information in real time, optimizing response time and decision-making process. For larger-scale events (such as fire, earthquake, etc.), the real-time monitoring information and AR-assisted display provided by the platform can help commanders understand the status of each area in real time and coordinate various resources for emergency rescue.

[0049] Specifically, in step S5 of the embodiment provided by the present invention, the real-time monitoring information is substituted into the element building model to obtain a real-time monitoring model of the target building. The element building model is a digital model obtained through field detection of various building elements of the target building. It can provide digital simulation feedback on the safety status of the target building. The actual condition of the target building will change over time. These changes will affect the actual condition of the building elements, thereby affecting the safety status of the target building.

[0050] More specifically, the content of real-time monitoring information includes data collected by the sensor group inside the target building and image data collected by the AR device. By analyzing the sensor group data and image data, the changes in various internal building elements of the target building can be obtained. Therefore, a small number of detection equipment can be used to achieve comprehensive detection of various building elements of the target building, thereby realizing the assessment of the safety status of the target building.

[0051] It can be understood that building elements have corresponding existence forms and evaluation standards, so the correlation between building elements and sensor group data and image data is fixed. By feedback on the changes in the status of the target building based on the sensor group data and image data, the changes in the various building elements of the target building can be obtained.

[0052] Specifically, in step S6 of the embodiment provided by the present invention, based on monitoring data and element information in the building model (such as rooms, floors, equipment, and pipelines), an algorithm characterizes the real-time status of each location. The real-time characteristics of each element are spatially mapped using the building model to generate a real-time element feature map for the specific area. Based on sensor monitoring data (such as smoke, fire alarms, gas leaks, and occupant density) and the status of safety facilities in the building model (such as fire extinguishers, emergency exits, and refuge routes), the safety risk of each area is analyzed. The likelihood of fire and the fire area are assessed based on factors such as fire sensor data, smoke detection, and temperature anomalies. Vibration sensor and crack monitoring data are used to assess the structural health of the building, particularly its safety in extreme weather conditions such as earthquakes and storms. Combined with data such as occupant density, evacuation route status, and security facilities, the safety risk of people in emergency situations is analyzed. The safety assessment results for each area are intuitively displayed in the building model through color coding and alarm identification, forming a "safety heat map." These safety feature distribution maps can help managers quickly determine the safety status of the building.

[0053] More specifically, the real-time building monitoring model updates the building's element status and safety data in real time, visually displayed through 3D rendering and AR / VR technology. Areas of varying status can be highlighted using different colors and symbols. For example, red indicates high-risk areas, yellow indicates medium-risk areas, and green indicates safe areas. This allows building managers and rescuers to interact with the model and query detailed data, risk levels, and historical trends for specific areas. For example, rescuers can view temperature changes, occupant density, and equipment status in affected areas to develop optimal rescue plans.

[0054] More specifically, based on real-time data analysis, the system can provide building managers with recommendations for preventive measures. For example, if a fire hazard is detected in a certain area, the system can recommend increasing ventilation, checking fire extinguishers, and activating fire alarms.

[0055] It is understandable that through the combination of building models and real-time monitoring information, rescue personnel can quickly obtain status information of various areas in the building when a disaster occurs, including temperature, humidity, gas concentration, population density, etc., especially in emergency situations such as fire or gas leakage, real-time data helps rescue personnel accurately judge the spread of fire, evacuation of personnel, etc., improve rescue efficiency and reduce losses. The real-time monitoring system can identify risk areas in the building (such as fire hazards, structural problems, etc.) and provide real-time feedback, which helps to respond quickly. Through real-time monitoring and analysis of the distribution of safety features, building managers can assess the safety status of each area, discover potential safety hazards (such as fire, electrical failures, gas leaks, etc.), and take preventive measures in time. Real-time data can help managers optimize emergency plans according to the real-time status of the building. For example, if the evacuation passage on a certain floor is found to be blocked, managers can adjust the evacuation route to ensure that people can evacuate quickly.

[0056] The present invention provides a method for applying comprehensive building element information, which has the following beneficial effects:

[0057] The present invention collects building information of the target building, constructs a building information model, collects building element data according to predetermined building elements to form an element building model, performs real-time monitoring through a sensor group and AR equipment, obtains real-time monitoring data and substitutes it into the element building model to generate a real-time monitoring model, analyzes the actual characteristics and safety characteristics of the building elements according to the real-time monitoring model, evaluates the safety status of the building, assists in disaster response and prevention measures, and accurately describes the real-time status of various parts of the building by collecting building information and building element data and combining them with real-time monitoring information to detect safety hazards, improve the building disaster response capability and management efficiency, and solves the problem of safety hazards that are easily missed through manual building safety inspections in the existing technology.

[0058] Preferably, the steps of collecting building information of a target building to obtain the building information of the target building, and constructing a building information model for providing digital feedback of the target building based on the building information include:

[0059] S11: Determine the building location information of the target building in the urban area where the building is located, and obtain the corresponding basic building model from the urban information platform according to the building location information;

[0060] S12: Acquire building information of the target building through field detection, and modify the basic building model according to the building information to obtain a building information model for digital feedback of the target building.

[0061] Specifically, the geographic location of the target building needs to be determined. Using GIS (Geographic Information System) technology or GPS positioning systems, the precise coordinates and address of the target building within the urban area can be obtained. By analyzing urban planning and building distribution information, the surrounding environment of the target building, including adjacent buildings, roads, and transportation facilities, can be understood. This helps further analyze the location characteristics of the target building and its relationship to the surrounding environment.

[0062] More specifically, the city information platform is a database containing a vast amount of basic building data, typically encompassing urban planning, architectural design standards, building layout, and infrastructure. By connecting to the city information platform, the basic building model of the area where the target building is located is obtained. This basic building model includes information such as the building's exterior outline, number of floors, floor layout, and structural type (e.g., reinforced concrete, steel). Based on the target building's location information, the relevant basic building data is extracted from the city information platform. In addition to the building's exterior shape, information on the building's infrastructure (e.g., electrical, plumbing, HVAC, and other facility layouts) and their operational status should also be obtained.

[0063] More specifically, through on-site surveys, using laser scanning (LiDAR), photogrammetry, drones, ground mapping and other technical means, detailed building data of the target building is obtained, including precise measurement of the building's external dimensions, internal space distribution, room layout, floor height, etc. Building structure: recording the building's structural type, load-bearing walls, support columns and other major structural parts; Equipment and pipelines: detecting the layout of key equipment and pipelines such as the electrical system, water supply and drainage pipes, and air-conditioning systems in the building; Building environment data: collecting data such as the terrain, wind speed, and climate of the building's surroundings in order to have a more comprehensive understanding of the building's operating environment; Data collection: through the above-mentioned detection methods, a large amount of building data is collected, especially detailed data that is different from or omitted in the actual and basic building models.

[0064] More specifically, the data obtained from field surveys is compared with the basic building model obtained from the city information platform to identify any discrepancies and correct any inaccuracies or missing parts. Specific corrections include, for example, correcting geometric information such as building facades, floor heights, and window distribution using laser scanning or photogrammetry data. Structural and facility corrections: Based on field data, the layout and location of the building's structural components (such as walls, beams, and columns) and internal facility pipelines (such as electrical distribution and water supply and drainage pipes) are updated. Environmental and safety corrections: If safety hazards or damaged facilities are found in the building during actual surveys, the building model can be annotated and adjusted to ensure that the model reflects the building's actual condition.

[0065] More specifically, a complete and accurate Building Information Model (BIM) is constructed using the revised building information. This model includes not only the building's geometric data but also its structure, equipment, systems, and performance data. This model is fed back digitally to the BIM, creating a continuously updated feedback mechanism. The building's actual operating data (such as energy consumption, equipment status, and environmental data) can be connected to the BIM model, providing real-time feedback on the building's operational status and ensuring consistency between the model and actual conditions.

[0066] It is understandable that by combining field surveys with urban information platforms, the accurate collection and updating of building information can be ensured, making the BIM model more realistic and reliable. Especially for complex buildings and historical buildings, field surveys can make up for the deficiencies in traditional planning drawings, accurately obtain the actual structure and facility information of the building, and compare and correct the field data with the basic model, avoiding deviations caused by errors or data lags in the design and construction process, and improving the quality of building information.

[0067] Preferably, the step of collecting corresponding data of the target building based on a plurality of pre-planned building elements to obtain element information of the target building corresponding to each of the building elements includes:

[0068] S21: Defining the content of the collected building elements to obtain element content standards and element evaluation standards for each building element; wherein the element content standards are used to describe the content form of the building elements, and the element evaluation standards are used to describe the information format standards that need to be converted before the content form of the building elements is substituted into the building information model;

[0069] S22: collecting corresponding data of the target building according to the element content standard of the building element to obtain element content data of the target building corresponding to the building element; wherein the element content data is used to describe the information status of each specific location of the target building corresponding to the building element;

[0070] S23: Evaluate and process the element content data according to the element evaluation standard of the building element to obtain element information of the target building corresponding to the building element; wherein the element information is used to describe the standard format information of the building element corresponding to each specific location of the target building.

[0071] Specifically, to ensure that the content of each building element is clear and standardized, each element needs to be defined in detail. The main task of this stage is to classify each building element and clarify the content they involve. Building elements may include but are not limited to building structure, building facilities, environmental parameters, equipment operating status, etc. The element content standard specifically describes the content form, data items, attributes, measurement methods, etc. of the building elements.

[0072] More specifically, in order to effectively import the collected building element information into the building information model (BIM), the collected data needs to be uniformly evaluated and processed. This evaluation standard should describe the requirements for converting data into a BIM format and ensure its application in the BIM system. The element evaluation standard is mainly used to explain how to process and convert data into a format that conforms to the BIM model after collection. It usually includes: data conversion rules: such as how to convert the original collected data into a data format supported by BIM (such as IFC, Revit format, etc.), data verification standards: verify the accuracy and consistency of the collected data to ensure that the information is complete and correct, data structure specifications: ensure that the data is organized according to the preset hierarchical structure, attributes and relationships, so that it can be effectively managed and applied in the BIM system.

[0073] More specifically, modern building measurement tools such as laser scanning, drone aerial photography, BIM model collision detection tools, IoT sensors, etc. are used to collect building elements in detail. The data collection method should be based on the complexity of the target building and the requirements of the element content. During the data collection process, the content of each building element should be verified one by one to ensure that the collected data is consistent with the preset content standards. Any abnormal or missing elements should be identified in a timely manner and supplemented or re-measured.

[0074] More specifically, based on the evaluated and processed data, the building element information of the target building is generated. This information complies with the BIM standard format (such as IFC format, Revit, etc.) and describes in detail the specific location, function, status, etc. of each element. The standardized information of each building element should include: spatial location, physical properties, structure and system integration, maintenance and management information: including the maintenance history, service life, inspection cycle, etc. of the element, which can be directly imported into the BIM system to supplement or update the existing building information model.

[0075] It's understandable that standardized definitions of building elements ensure the comprehensiveness and accuracy of collected data. Clarifying the content and evaluation criteria for each building element effectively reduces errors and omissions in data collection, improving efficiency and quality. Once the data has been evaluated and formatted, it can be seamlessly imported into the BIM system, ensuring consistency between the BIM model and actual building data. This standardized data also enables the BIM system to better manage all building information.

[0076] Preferably, the step of monitoring the target building in real time by using a sensor group and an AR device preset inside the target building to obtain real-time monitoring information of the target building includes:

[0077] S41: Pre-planning information items that need to be monitored in real time in the target building, and analyzing the monitoring location of each information item based on the building information model to obtain the monitoring location of each information item corresponding to the target building; wherein the information items include temperature information, smoke information, and water pressure information;

[0078] S42: Setting relevant sensor groups for the target building according to the project monitoring positions of the respective information items, so as to collect data of the information items of the target building through the project sensor groups set at the project monitoring positions, so as to obtain project monitoring information corresponding to the respective information items of the target building;

[0079] S43: Pre-planning and analyzing the locations in the target building where visual information collection is required based on the building information model to obtain the visual information collection locations of the target building;

[0080] S44: Setting an AR device for the target building according to the visual information collection position, so as to collect visual information of the target building through the AR device set at the visual information collection position to obtain visual information of the target building;

[0081] S45: The project monitoring information corresponding to each information item of the target building and the visual information together constitute the real-time monitoring information of the target building.

[0082] Specifically, determine which information items require real-time monitoring and develop a monitoring plan for them. These include: Temperature: Monitoring internal building temperatures to ensure comfort and safe equipment operation; Smoke: Monitoring fire risks and detecting smoke promptly; and Water Pressure: Monitoring water pressure changes in the water pipe network to prevent pipe damage or leaks.

[0083] More specifically, the building's usage and safety requirements determine which information items require real-time monitoring. Appropriate sensor monitoring items are selected based on the building's function and usage. Common options include temperature and humidity, smoke detection, water pressure, and power consumption.

[0084] More specifically, building information models are used to analyze specific locations within a building that require monitoring, and appropriate planning is performed. Leveraging BIM technology, the optimal monitoring locations for each information item within the target building are analyzed. For example, temperature monitoring is typically required in multiple areas of a building, particularly key locations within the HVAC system. Smoke detectors are typically placed in high-risk areas such as kitchens, electrical equipment rooms, and machine rooms. Water pressure monitoring is required at key points within the plumbing system, such as pump rooms and pipe junctions.

[0085] More specifically, the data in the BIM model (such as room size, purpose, building structure, etc.) is used to determine the optimal monitoring location for each information item. Sensor groups are set up in the building based on the determined locations to collect data on information items such as temperature, smoke, and water pressure in real time.

[0086] More specifically, based on the results of BIM model analysis, sensors (temperature sensors, smoke sensors, water pressure sensors, etc.) are installed, and sensor groups are deployed in appropriate locations (such as walls, ceilings, pipes, etc.) to ensure that real-time data is collected. Each sensor group monitors the data in real time. The sensors will upload the collected information (such as temperature, smoke concentration, water pressure values, etc.) to the data server or cloud platform in real time. The collected sensor data is transmitted to the central control system through the Internet of Things (IoT) technology for processing and storage. The monitoring data may include: real-time temperature change curves, smoke concentration indicators, real-time monitoring of water pressure values, etc. The data of the sensor group can be used for subsequent alarm systems (such as excessive temperature, excessive smoke concentration, etc.) and analysis systems to ensure the safety and normal operation of the building.

[0087] More specifically, based on the BIM model, plan the key locations inside the building where visual information collection is required. These locations can be areas that need to be monitored and inspected, or areas where building data is visualized through AR devices. Based on the building's layout, functional requirements, and safety protection needs, analyze and determine the locations where visual information needs to be collected through AR devices, and determine the visual collection locations: These locations may include: safety-critical areas: such as exit passages, electrical equipment rooms, fire emergency areas, etc., equipment maintenance areas: such as mechanical equipment rooms, power rooms, etc., to ensure visual assistance during maintenance and inspection, aerial and remote areas: for locations that cannot be directly accessed or difficult to shoot, use AR devices for virtual monitoring.

[0088] More specifically, AR devices are set up based on pre-defined visual information collection locations to capture real-time visual information about the building, which is then visualized using augmented reality technology. AR devices are deployed at locations determined by BIM model analysis. These devices include, but are not limited to: AR headsets (such as Microsoft HoloLens and Magic Leap) for on-site visualization of data; AR glasses or mobile devices for facilitating on-site inspections, maintenance, and operations; and AR cameras and sensors that work in conjunction with sensors within the building to achieve real-time integration of data and visual information.

[0089] More specifically, AR devices can be used to capture real-time visual data from the construction site. This data may include: Real-time display of building structure layers: This combines the building model in BIM with the actual environment to display real-time information about equipment, pipelines, walls, etc.; Facility status display: This overlays real-time status information such as equipment failures, temperature anomalies, and smoke alarms within the equipment's field of view; and Augmented Reality visualization: AR devices combine real-time monitoring data with the building model to create an augmented reality effect. Through AR devices, staff can see the actual building conditions and corresponding sensor monitoring information.

[0090] More specifically, the real-time monitoring information collected by the sensor group is combined with the visual information provided by the AR device to form a comprehensive real-time monitoring information system for the target building. The data from the sensor group (temperature, smoke, water pressure, etc.) is integrated with the visual information collected by the AR device. Through the AR device, building managers can see the status data of various areas of the building in real time, and understand key information such as temperature changes, smoke concentration, water pressure, etc. in combination with the sensor data. Through AR technology, the real-time monitoring information of the building will be directly presented to the management personnel. For example, it can be shown that the temperature in a certain area exceeds the set threshold, the smoke detection system has triggered an alarm, the water pressure is abnormal, etc. If the sensor data detects an abnormality, the AR system can automatically generate an alarm prompt, help staff locate the problem area, and provide solutions or guidance.

[0091] It is understandable that by collecting key building information (such as temperature, smoke, water pressure, etc.) in real time through sensors, it is possible to issue alarms in time when anomalies occur, reducing safety risks. AR devices provide real-time and intuitive building status views, allowing managers to understand the current status of the building more efficiently and accurately during maintenance, inspections, etc., providing a dynamic visual environment to help managers make decisions more quickly and deal with potential safety hazards or failures. Through the linkage of sensors and AR devices, the operating status of each area of the building can be understood in real time, the workload of manual inspections can be reduced, and the efficiency of operational management can be improved. Combining the real-time monitoring information of the building with AR technology can enable staff to perform facility maintenance and emergency response more accurately, reduce misoperation and delays, and in emergency situations such as fires and pipeline leaks, AR devices can provide real-time guidance to help staff quickly locate problems and take corresponding measures.

[0092] Preferably, the step of analyzing the target building according to the real-time monitoring model to obtain the actual feature distribution of the elements of the target building includes:

[0093] S611: performing a state change analysis on the real-time monitoring model in a continuous time relationship to obtain monitoring information change characteristics of the real-time monitoring model;

[0094] S612: Analyzing the degree of correlation of the influence of each building element based on the monitoring information change characteristics to obtain element correlation change characteristics of each building element as fed back by the monitoring information change characteristics; wherein the element correlation change characteristics include the information change portion of the monitoring information change characteristics that is correlated with the building element;

[0095] S613: Acquire the monitoring time of the real-time monitoring model, and analyze the collection completion time of each of the building elements according to the monitoring time to obtain the collection completion time of the building elements;

[0096] S614: performing a simulation analysis of element degradation on the building element according to the completion time of collection of the building element, so as to obtain a probability distribution of element degradation of the building element at the current moment; wherein the probability distribution of element degradation includes several degradation degrees of the building element and degradation probabilities corresponding to the various degradation degrees;

[0097] S615: performing confidence processing on the element degradation probability distribution according to the element correlation change characteristics of the building elements to obtain the actual degradation characteristics of the building elements; wherein the actual degradation characteristics are used to describe the real-time status of the building elements in the target building;

[0098] S616: Combining the degradation actual characteristics of each of the building elements to obtain the actual characteristic distribution of the elements of the target building.

[0099] Specifically, the time-varying characteristics of various monitoring information in the real-time monitoring model are analyzed to reveal the health status and changing trends of each element of the target building. Time series analysis is performed on the monitoring information in the real-time monitoring model (such as temperature, humidity, smoke concentration, water pressure, etc.) to identify the changing patterns of the monitoring data over different time periods. By analyzing the temporal changes of this monitoring information, the operating status of building elements and their cyclical changes can be identified. For example, some facilities may experience seasonal fluctuations (such as HVAC systems), while other equipment may experience non-cyclical fluctuations based on usage frequency, load, or environmental changes. Through this analysis, the changing characteristics of the monitoring information, such as fluctuation amplitude, changing trends, and cyclical patterns, are extracted to provide data support for subsequent analysis.

[0100] More specifically, based on the changing characteristics of monitoring information, the interplay between different building elements is analyzed to identify which building element changes have the greatest impact on other elements. This data is then used to establish a relationship model between these elements. Statistical methods (such as correlation analysis and regression analysis) are used to calculate the degree of correlation between these elements. For example, temperature changes may be closely related to the operating status of the air conditioning, heating, and electrical systems, while changes in smoke concentration are highly correlated with the operation of the fire protection and ventilation systems. Based on the changing characteristics of monitoring information and the degree of correlation between building elements, it is possible to analyze which element changes have the greatest impact on other building elements, and the patterns of these impacts. For example, temperature changes may affect the load of the HVAC system, but they may also affect electricity consumption through changes in heat load.

[0101] More specifically, based on the monitoring system's collection time, the completion time of each building element's collection is analyzed, and the integrity and timeliness of its data are evaluated. The collection time information for each monitoring point is extracted from the real-time monitoring model. Monitoring time can include the time span from the start of system collection to the current moment. Based on the monitoring time, the completion time of each building element's collection is analyzed. This can be determined by the update timestamp of the monitoring data, assessing the timeliness and frequency of data collection. For example, some systems may collect data in real time (such as temperature and humidity monitoring), while others may collect data periodically (such as regular inspection data and equipment operating status). Based on the completion time of monitoring data, it is possible to analyze which building elements have the most up-to-date monitoring data and which may be lagging, thus affecting subsequent degradation analysis.

[0102] More specifically, based on the collection time of each building element, the system simulates and analyzes the degradation trend of each element, assessing its current probability distribution. Leveraging existing equipment maintenance data, lifespan prediction models, and collected real-time monitoring information, the system analyzes the degradation process of each building element. For example, the degradation process of an air conditioning system can be simulated based on temperature fluctuations and operating time, while the risk of wear, corrosion, or leakage in a piping system can be simulated based on changes in water pressure.

[0103] More specifically, the model simulates the degradation trend of each building element and derives the degradation probability distribution of each element at the current moment. This includes the probabilities corresponding to various degrees of degradation (such as mild degradation, moderate degradation, severe degradation, etc.). For example, the probability of a certain air-conditioning system being mildly degraded is 30%, the probability of being moderately degraded is 50%, and the probability of being severely degraded is 20%.

[0104] More specifically, based on the changing characteristics of element correlations, the degradation probability distribution of building elements is subjected to confidence processing to obtain more accurate actual degradation characteristics. Using methods such as Bayesian reasoning or fuzzy logic, combined with the changing characteristics of real-time monitoring information (such as temperature, humidity, smoke information, etc.), the degradation probability of each building element is corrected to generate a more accurate degradation probability distribution.

[0105] For example, if the monitoring information of a building element changes significantly (such as an increase in temperature variation), it may mean that the degradation risk of the element has increased. Confidence processing will adjust the degradation probability distribution and increase the confidence level of the occurrence of degradation.

[0106] More specifically, the confidence-processed degradation probability distribution can be used to derive the actual degradation characteristics of each building element, describing the most likely health state of that element at the current moment. This provides building operators with more accurate equipment status data.

[0107] More specifically, the actual degradation characteristics of all building elements are combined to obtain the comprehensive actual characteristic distribution of each element in the target building, comprehensively assessing the overall health of the building. The actual degradation characteristics of each building element (including the degree of degradation of each element and its corresponding probability) are combined to form the comprehensive element actual characteristic distribution of the target building. For example, the degradation status of multiple elements such as temperature, humidity, power system, pipelines, and fire-fighting equipment will jointly affect the overall operation of the building.

[0108] More specifically, by analyzing the distribution of the actual characteristics of the elements, we can understand the overall health status of the target building at the current moment and identify which elements are at high risk of deterioration and which are in a healthy state. Based on this analysis, building managers can adjust operational strategies in a targeted manner and perform maintenance, inspection or replacement of equipment in advance, thereby reducing equipment failure rates and improving the long-term sustainability of the building.

[0109] Preferably, the step of analyzing the target building according to the real-time monitoring model to obtain the building safety feature distribution of the target building includes:

[0110] S621: Analyze the target building according to the real-time monitoring model to obtain the actual feature distribution of the elements of the target building;

[0111] S622: Substituting the actual feature distribution of the elements into the real-time monitoring model to obtain an actual feature model, and performing several types of potential risk analysis on the target building based on the actual feature model to obtain several potential risk features of the target building;

[0112] S623: simulating the dangerous conditions of each of the potential risk features according to the actual condition model of the element to obtain the simulated dangerous conditions of the target building corresponding to each of the potential risk features;

[0113] S624: simulating the response plan for the simulated dangerous situation according to the actual model of the elements, so as to obtain a dangerous situation response plan corresponding to each of the simulated dangerous situation;

[0114] S625: Evaluate the safety index of each specific location of the element real-time model according to each of the simulated dangerous situation conditions and each of the dangerous situation response plans, so as to obtain the safety index of each specific location of the element real-time model;

[0115] S626: Integrate the safety indexes of the specific locations of the element real-life model to obtain the building safety feature distribution of the target building.

[0116] Specifically, through the real-time monitoring model, the actual characteristic distribution of each building element in the target building is analyzed and obtained as the basic data for building safety analysis. The real-time monitoring model is used to monitor and analyze the various building elements of the building (such as structure, equipment, facilities, environment, etc.), and the actual characteristics of each element at the current moment are extracted. The actual characteristics of the elements include the current health status, operation status and change trends of the building elements, such as temperature, humidity, smoke, gas concentration, pressure, vibration and other sensor data, combined with the operating status of the equipment (such as air conditioning, power system, etc.) and structural health monitoring (such as crack detection, deformation monitoring, etc.). Through time series analysis and spatial distribution analysis of the data, the distribution characteristics of each building element are obtained, for example, which areas have too high temperatures and which areas may have problems such as excessive electrical loads.

[0117] More specifically, the acquired real-time characteristic data of elements is fed into the real-time monitoring model to generate a "real-time element model," which provides a foundation for potential risk analysis. Based on the real-time monitoring data, the real-time characteristics of each element are used as input to construct the real-time element model. This model can simulate and predict the current and future states of different elements, such as equipment health, structural stress, and environmental changes. The real-time element model is a dynamic model that updates in real time based on changes in real-time monitoring data to ensure an accurate reflection of the status of each building element.

[0118] More specifically, based on the actual element model, the system analyzes potential safety risks in the target building, identifies risk types and characteristics, and identifies potential risks in various elements of the building by analyzing the actual element model. Examples include: structural risks, such as cracks, subsidence, and tilt in the building structure; fire risks, such as electrical failures, abnormal temperatures, and smoke concentrations; flood risks, such as leaking pipes and drainage system failures; and environmental risks, such as gas leaks and decreased air quality. Risk characteristic analysis: Based on data from the actual element model, the system analyzes the probability of occurrence, scope of impact, and potential consequences of each risk. For example, the power system may have the risk of short circuits or overloads, while the HVAC system may cause temperature instability and equipment damage. Identified risks are categorized and their characteristics analyzed, such as fire risk, structural instability risk, and equipment failure risk.

[0119] More specifically, based on the actual element model, various potential risks are simulated, predicting the specific scenarios in which risks occur. Based on the risk characteristics, different types of dangerous situations are simulated. For example, for power system overload risks, the specific scenarios of power system failures can be simulated to predict the impact of short circuits on building safety. For structural risks, the impact of settlement and deformation of a certain part of the building can be simulated. Through virtual simulation, computational fluid dynamics (CFD) models, finite element analysis (FEA), and other technical means, the development process of potential risks in the building is simulated to obtain the specific dangerous situations and consequences that may result from the occurrence of risks. According to different risk categories, the development process of dangerous situations under multiple different scenarios is simulated to ensure comprehensive prediction of various potential risks.

[0120] More specifically, based on the results of the hazard simulation, corresponding emergency plans are formulated, and the execution effects of the plans are simulated to ensure a rapid response when a hazard occurs. According to the simulated conditions of various hazard situations, corresponding emergency plans are formulated, such as: emergency plans for fire risks: including fire alarm, emergency evacuation, activation of fire extinguishers, etc., emergency plans for structural instability: including support frame construction, emergency reinforcement, personnel evacuation, etc., emergency plans for electrical failures: including power outages, equipment isolation, etc., emergency response simulation: under simulated hazard conditions, the effectiveness of various emergency plans is tested, and factors such as the time for plan execution, resource requirements, and personnel collaboration are analyzed; according to the simulation results, the emergency plans are optimized to improve the emergency response speed and the feasibility of the plans.

[0121] More specifically, based on the simulated hazard conditions and response plans, the safety index of each location in the target building is evaluated, the safety of each area is measured, and the safety index of each area of the building is evaluated based on the simulated hazard conditions and the corresponding emergency plans. Safety index assessments generally consider the following factors: Risk level: the impact of the severity of different risks on the safety index; Emergency plan effectiveness: the contribution of the implementation of the emergency plan to building safety; Historical data: the occurrence of similar incidents in history and the effectiveness of their handling. Location safety index: Based on the different locations in the building (such as floors, areas, equipment, etc.), the risk exposure, emergency response capabilities, etc. are evaluated to derive the safety index of each location. Risk tolerance: Based on the structural characteristics and use of the building, a tolerance threshold for the safety index is set to ensure that the overall safety level of the building is within an acceptable range.

[0122] More specifically, the safety indexes of various locations are integrated to obtain the overall safety feature distribution of the building, thereby providing decision-making support for building management. The safety indexes of various locations in the building are weighted and integrated to obtain a comprehensive building safety feature distribution. These safety indices not only reflect the immediate safety status of each location, but also reflect the overall safety level of the building. Through the integration of safety indices, a safety risk distribution map of the building is generated, indicating which areas or equipment have higher risks and which areas or equipment are safer. The safety feature distribution map provides building managers with an intuitive overview of the safety status, helping them to identify priority risk areas and formulate targeted safety management measures.

[0123] Preferably, the step of evaluating the safety index of each specific location of the element real-life model according to each of the dangerous situation simulation conditions and each of the dangerous situation response plans to obtain the safety index of each specific location of the element real-life model includes:

[0124] S6251: Analyzing the probability of occurrence and the degree of danger of each specific location of the element actual model according to each of the simulated danger conditions, so as to obtain a negative safety index for each specific location of the element actual model;

[0125] S6252: Analyzing the timeliness and success rate of emergency response at each specific location of the element real-time model according to each emergency response plan, so as to obtain a positive safety index for each specific location of the element real-time model;

[0126] S6253: Combine the negative safety index and the positive safety index of each specific location of the element real-life model to obtain the safety index of each specific location of the target building.

[0127] Specifically, the negative impact of potential risks occurring at specific locations of the target building is evaluated, that is, the probability and severity of the dangerous situation, and the negative safety index of each location is obtained. Different risk scenarios (such as fire, structural instability, power failure, etc.) are simulated through real-time monitoring models to evaluate the safety risks of each area under these scenarios. Based on historical data, environmental changes and monitoring data, the probability of specific risk events is calculated, such as the probability of electrical system overload and the possibility of crack expansion in the building structure.

[0128] More specifically, the simulation results assess the severity of each hazard, taking into account the scope, extent of damage, and consequences of a hazard. For example, factors such as the speed of smoke spread and the extent of structural damage during a fire are considered. Based on the probability and severity of each hazard, a negative safety index is calculated for each location.

[0129] More specifically, the timeliness and success rate of emergency response in the event of a dangerous situation at each specific location of the target building are evaluated to obtain a positive safety index for each location. For each potential risk, the corresponding emergency plan is evaluated, including the emergency response time and the emergency response success rate. Based on the building's emergency response plan, the time from the occurrence of the dangerous situation to the activation and execution of the emergency plan is evaluated. Taking into account the deployment of various emergency response facilities (such as fire protection, evacuation, alarms, etc.), the timeliness of the emergency response is calculated.

[0130] More specifically, the success rate of emergency response measures is evaluated, taking into account factors such as the functional status of emergency equipment, personnel training, and operating procedures. For example, the success rate of fire extinguishing system activation and the success rate of automatic power system shut-off are evaluated. Forward safety index: Based on the timeliness and success rate of emergency response at each location, the forward safety index of the location is calculated. The values of emergency response timeliness and success rate are usually obtained through simulation or historical data. The higher the value, the stronger the emergency response capability and the higher the building safety.

[0131] More specifically, through the comprehensive processing of the negative safety index and the positive safety index, the final safety index of each location is obtained, which reflects the overall safety level of the location. The negative safety index and the positive safety index of each location are weightedly combined. Specifically, the negative safety index reflects the severity of potential risks, while the positive safety index reflects the ability to respond to emergencies. The combination of the two can comprehensively reflect the safety status of the building.

[0132] More specifically, the final comprehensive safety index can be analyzed by different dimensions such as area, floor, and equipment to reveal the safety status of different areas of the building. For example, some areas may have a lower safety index due to higher risks, while other areas may have a higher safety index due to improved emergency plans.

[0133] It is understandable that by combining potential risks and emergency response capabilities, it is possible to comprehensively and dynamically assess the safety of various locations in the building, identify areas with higher risks, and provide timely safety warnings for building managers. Not only the severity of potential risks (negative safety) is considered, but also emergency response capabilities (positive safety) are incorporated into the evaluation system to ensure that the building has sufficient emergency response capabilities to effectively deal with risks when they occur, reducing the possibility of safety accidents. Combined with the safety index assessment results, managers can more accurately identify high-risk areas and weak links, optimize resource allocation and safety strategies, and improve the overall safety level of the building.

[0134] Preferably, the method further includes: searching and locating firefighting facilities within the surrounding area of the building information model through a city information platform to obtain positioning information of firefighting facilities around the building information model, converting and processing the positioning information to obtain a rescue unit, analyzing a rescue path and its movement efficiency of the rescue unit and the building information model according to the city information platform to obtain a rescue path and its movement efficiency between the rescue unit and the building information model, and correcting a building safety feature distribution of the target building according to the rescue path and its movement efficiency to obtain a rescue safety feature distribution of the target building; wherein the rescue safety feature distribution is used to describe the safety level of each specific location of the target building when receiving rescue by the fire rescue facility;

[0135] An inspection and evaluation of the rescue safety feature distribution is performed according to preset standards to determine a safety inspection plan for the target building.

[0136] Specifically, the city information platform is used to conduct a comprehensive search and positioning of fire-fighting facilities around the target building to obtain the specific location of the fire-fighting facilities, providing basic data for subsequent rescue path analysis. The building information model (BIM) is integrated with the city information platform, and the platform's data resources are used to conduct real-time queries on the fire-fighting facilities around the building.

[0137] More specifically, through the urban information platform, the location of fire-fighting facilities around the building, including information such as fire stations, fire water sources, and fire-fighting equipment, is obtained. The coordinates of the location data of the fire-fighting facilities are converted, and the geographical location information of the fire-fighting facilities is connected with the coordinates of each location in the building information model. Through the spatial matching algorithm, the location information of the building model and the surrounding facilities can be accurately connected. After the fire-fighting facility positioning is completed, the fire-fighting facility location information related to the building information model is generated, including distance, direction, etc., for subsequent path analysis.

[0138] More specifically, based on the rescue path and mobility efficiency between the fire rescue unit and the target building, it is evaluated whether the rescue unit can reach the building in time, and the impact of its mobility efficiency on the rescue effect is judged. Based on the positioning information of the firefighting facilities and the surrounding rescue resources, the available fire rescue units are determined, such as fire trucks, ambulances, fire extinguishing equipment, etc.

[0139] More specifically, the shortest path for rescue units from firefighting facilities to target buildings is calculated based on data from building information models and urban information platforms. Path analysis can be performed using a variety of algorithms (such as Dijkstra and A*) to calculate the optimal rescue path. In addition to calculating the shortest path, the mobility efficiency of rescue units must also be considered, taking into account factors such as traffic conditions, road restrictions, and traffic signals. This is analyzed using real-time traffic data, urban traffic models, and the performance of rescue units (such as the maximum speed of fire trucks and the degree of traffic congestion). The actual time it takes for rescue units to reach the target building is then determined. This generates the rescue path from the firefighting facilities to the target building and the corresponding mobility efficiency information, providing a basis for subsequent adjustments to the safety feature distribution.

[0140] More specifically, after understanding the rescue unit's path and movement efficiency, the building's safety profile distribution is modified to reflect the safety level of each location in the building under fire rescue support. Based on the safety data from the building information model, a preliminary safety profile distribution is first generated for the target building. These profiles include structural safety, fire protection equipment availability, escape route design, and fire risk areas. Using the rescue path and rescue efficiency analysis results, the building's safety profile is then modified. For example, the rapid rescue zone modification improves the safety of areas close to the rescue unit and with clear paths. Delayed rescue zone modification reduces the safety of areas with longer rescue times and complex paths, reflecting the higher risk of these areas. Based on these modified results, the safety profile of each location in the building is updated to form a new "rescue safety profile distribution map." This map shows the changes in safety at various locations in the building after receiving fire rescue assistance.

[0141] More specifically, based on the revised rescue safety feature distribution, the safety status of the target building is assessed and a corresponding safety inspection and maintenance plan is developed. Based on the building's safety regulations, fire standards, and risk assessment requirements, a set of pre-set criteria is set to evaluate the compliance of the rescue safety feature distribution. For example, each area's safety index may need to meet a certain standard, or certain high-risk areas may require special attention. The building's safety status is assessed based on the revised rescue safety feature distribution and pre-set criteria. During the assessment, various technical methods (such as risk analysis models and Monte Carlo simulations) can be used to comprehensively examine the building's rescue safety features. This safety assessment identifies areas with low safety indexes or poor rescue efficiency, which may require focused inspections. Based on the assessment results, specific safety inspection and maintenance plans are developed for high-risk areas. These plans may include adding firefighting equipment, improving escape routes, and optimizing the layout of the fire protection system. Through assessment and revision, the safety inspection and maintenance plan is optimized and adjusted and optimized during the building's subsequent maintenance to ensure long-term safety management.

[0142] It is understandable that through the precise data integration and path analysis of the urban information platform, the location of surrounding fire-fighting facilities and the optimal path of the rescue unit can be obtained in real time. This precise positioning and path analysis greatly improves the efficiency and effectiveness of emergency rescue. By correcting the distribution of building safety characteristics according to the rescue path and efficiency, the safety assessment of each area of the building can be dynamically adjusted to ensure that the building can provide the best emergency response in the event of a disaster.
