DETAILED DESCRIPTION

[0008] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0009] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0010] Reference Figure 1 , Figure 2 As shown, a preferred embodiment of the present invention is provided.

[0011] In a first aspect, the present invention provides a method for applying comprehensive information of building elements, comprising: S1: collecting building information of a target building to obtain the building information of the target building, and constructing a building information model for digital feedback of the target building according to the building information; S2: collecting corresponding data of the target building based on several pre-planned building elements to obtain element information of the target building corresponding to each of the building elements; wherein the building elements include fire passages, evacuation passages, building structures, key parts, key areas, fire fighting forces, rescue equipment, and command deployment; 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; S4: 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; S5: Substituting the real-time monitoring information into the element building model to obtain a real-time monitoring model of the target building; 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 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.

[0012] Specifically, in step S1 of the embodiment provided by the present invention, an on-site survey is conducted on the target building to collect basic information of the building, including the building's structure, design drawings, floor layouts, installation locations of pipelines 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, pipelines, floor distribution, fire-fighting facilities, evacuation routes, structural nodes, etc.

[0013] 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 buildings. 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. are 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.

[0014] More specifically, use professional BIM software (such as Revit, Navisworks, etc.) 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 floor plan and three-dimensional spatial data should be 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.

[0015] 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, which can 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 operation status, etc.). On the basis of the BIM model, a digital feedback function is designed to allow the building's operation 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.

[0016] 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 locations of fire hydrants in the building; evacuation passages: passages, stairs, emergency doors, etc. used for personnel evacuation; building structures: the frame structure, supporting columns, walls, floor layouts, etc. of the building; key parts: including key facilities and areas such as electrical equipment rooms, main water pipelines, and transformer rooms; 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.

[0017] More specifically, through on-site investigation and measurement, accurate data collection is carried out on various relevant elements of the target building based on the 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 channel layout, doors and windows, stairs, and floor layout inside the building to confirm the width, height, passability and evacuation signs of the channel. 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, computer rooms, gas pipelines, and their spatial positions, dimensions, related equipment, etc. are marked. The location and working status of all fire-fighting facilities are collected, including the distribution maps of facilities such as fire extinguishers, fire hydrants, fire extinguishing systems, smoke detectors, and automatic sprinkler systems. The command center, emergency communication system, monitoring center and other facilities inside and outside the building are located.

[0018] More specifically, all the collected building element data will be sorted 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. The 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.

[0019] 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, real-time monitoring of the working status of fire-fighting equipment, whether the evacuation passages are unobstructed, whether there are safety hazards in key areas, etc., provides real-time feedback to emergency response personnel in the building, ensures that they can understand the specific situation when a disaster occurs in a timely manner, and optimize rescue routes and resource allocation.

[0020] 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 positions of the building information model are labeled corresponding to each building element to obtain the element building model of the target building.

[0021] 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.

[0022] 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 to carry out safety inspections on the target building.

[0023] 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 positions according to their functions. For example: Fire equipment area: arrange smoke detectors, temperature sensors, fire alarms, etc.; electrical equipment room or machine room: arrange temperature and humidity sensors, vibration sensors, etc.; evacuation passages and public areas: arrange motion sensors, cameras, etc. to monitor the evacuation of personnel in real time; environmental monitoring: such as CO2 concentration, air quality monitoring, etc., 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 data can be collected in real time and accurately.

[0024] More specifically, various sensors transmit real-time monitoring data to the central control system or cloud platform through wireless or wired networks (such as Wi-Fi, LoRa, 5G, etc.). The data collected by the sensors include temperature, humidity, motion status, gas concentration, power consumption, equipment status, etc. 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 are used near the sensor group to perform preliminary filtering, analysis, and preprocessing of data.

[0025] More specifically, an AR device is installed inside the building, usually an AR glasses, AR tablet or mobile phone and other terminals. The AR device needs to be connected to the sensor data system in real time to display real-time building monitoring information. The AR device superimposes the sensor data into the user's field of view through augmented reality technology. For example, on the display screen of the AR device, the temperature and humidity, air quality, CO2 concentration and other data in the building are superimposed. In the AR view in front of the device, the operating status of the device (such as temperature, power consumption, maintenance status, etc.) is superimposed. When the sensor triggers an alarm, the AR device displays the alarm information, emergency exit instructions, etc. More specifically, through motion sensors, AR devices display the distribution of people in the building in real time, especially 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.

[0026] More specifically, a central monitoring platform needs to be built to integrate sensor data and AR device information. The platform usually has the following functions: real-time display of data collected by each sensor, and presentation through charts, maps, warning information, etc.; real-time monitoring of the operating status of each device and area in the building, and timely detection of equipment failures or abnormal conditions; when sensor data exceeds the preset threshold, the system will issue an alarm and notify relevant personnel through AR devices, mobile phones or other terminals for processing. The platform must be able to support multi-user collaborative operations, such as building managers, security personnel, emergency response teams, etc. can view relevant data and alarm information through the platform.

[0027] More specifically, when the sensor detects an abnormality (such as fire, abnormal flow 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 device, the alarm information and emergency evacuation channels of the affected area are displayed in real time, helping the emergency response team to quickly formulate response measures. Through the building information displayed by the AR device, the team can view the building's floor plan, equipment location, channel status, emergency exits and other information in real time to optimize the 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.

[0028] 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, and these changes will affect the actual condition of the building elements, thereby affecting the safety status of the target building.

[0029] 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.

[0030] 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 feedbacking the sensor group data and image data on the changes in the status of the target building, the changes in the various building elements of the target building can be obtained.

[0031] Specifically, in step S6 of the embodiment provided by the present invention, based on the monitoring data and the element information (such as rooms, floors, equipment, pipelines, etc.) in the building model, the real-time status of each location is characterized by an algorithm, and the real-time characteristics of each element are spatially mapped through the building model to generate a real-time element characteristic map of a specific area. According to the sensor monitoring data (such as smoke, fire alarm, gas leakage, personnel flow density, etc.) and the status of the safety facilities (such as fire extinguishers, emergency exits, refuge passages, etc.) in the building model, the safety risk of each area is analyzed, and the possibility of fire and the fire area are evaluated according to the data of the fire sensor, smoke detection, temperature anomaly and other factors. The structural health status of the building is evaluated through the data of vibration sensors, crack monitoring, etc., especially the safety in extreme weather conditions such as earthquakes and storms. Combined with the data of personnel density, evacuation passage status, security facilities, etc., the safety risk of personnel in emergency situations is analyzed, and the safety assessment results of each area are intuitively displayed in the building model through color coding, alarm identification, etc. to form a "safety heat map". These safety feature distribution maps can help managers quickly judge the safety status of the building.

[0032] More specifically, in the real-time building monitoring model, the building's element status and safety status data are updated in real time, and visualized through 3D rendering and AR / VR technology. Areas in different states can be highlighted by different colors, logos, etc. For example, red indicates high-risk areas, yellow indicates medium-risk areas, and green indicates safe areas, allowing building managers and rescuers to interact with the model to query detailed data, risk levels, historical change trends, etc. of specific areas. For example, rescuers can view temperature changes, personnel density, equipment status, etc. in the disaster area, so as to formulate the best rescue plan.

[0033] More specifically, based on real-time data analysis results, the system can provide building managers with recommendations for preventive measures. For example, when a fire hazard is detected in a certain area, the system can recommend increasing ventilation, checking fire extinguishers, activating fire alarms, etc.

[0034] 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 evaluate the safety status of each area, discover potential safety hazards (such as fire, electrical failure, gas leakage, 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.

[0035] The present invention provides a method for applying comprehensive information of building elements, which has the following beneficial effects: The present invention collects building information of a 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 an AR device, 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's disaster response capabilities and management efficiency, and solves the problem of safety hazards that are easily missed through manual inspections of building safety in the prior art.

[0036] 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 digital feedback of the target building according to the building information include: 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; 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.

[0037] Specifically, it is necessary to determine the geographical location of the target building. Use GIS (Geographic Information System) technology or GPS positioning system to obtain the precise coordinates and address information of the target building in the urban area. Through urban planning and building distribution information, understand the surrounding environment of the target building, including adjacent buildings, roads, transportation facilities, etc., which will help further analyze the location characteristics of the target building and its relationship with the surrounding environment.

[0038] More specifically, the city information platform is a database containing a large amount of basic building data, usually including information such as urban planning, building design standards, building layout, and infrastructure. By connecting with the city information platform, the basic building model of the area where the target building is located is obtained. The basic building model includes information such as the building's appearance, number of floors, floor layout, and structural type (such as reinforced concrete, steel structure, etc.). According to the location information of the target building, the relevant basic building data is extracted from the city information platform. In addition to the building appearance data, the infrastructure information in the building (such as the layout of electrical, water supply and drainage, HVAC and other facilities) and its operating status should also be obtained.

[0039] More specifically, through on-site surveys, laser scanning (LiDAR), photogrammetry, drones, ground mapping and other technical means are used to obtain detailed building data of the target building, including precise measurement of the building's external dimensions, internal space distribution, room layout, floor height, etc. Building structure: record the building's structural type, load-bearing walls, supporting columns and other main structural parts. Equipment and pipelines: detect 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: collect 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: collect a large amount of building data through the above-mentioned detection methods, especially detailed data that is different from or missing in the actual and basic building models.

[0040] More specifically, the data obtained from the field survey is compared with the basic building model obtained from the urban information platform to find the differences and correct the inaccurate or missing parts. The specific corrections include, for example, correcting the geometric information such as the building facade, floor height, window distribution, etc. through laser scanning or photogrammetry data. Structural and facility corrections: Based on the field data, the layout and location of the building's structural components (such as walls, beams, columns, etc.) and the facility pipelines inside the building (such as electrical distribution, water supply and drainage pipelines, etc.) are updated. Environmental and safety corrections: In actual detection, if a building is found to have safety hazards or damaged facilities, the building model can be marked and adjusted to ensure that the model reflects the actual condition of the building.

[0041] More specifically, a complete and accurate building information model is constructed through the revised building information. The model includes not only the geometric data of the building, but also the structure, equipment, system, performance data, etc. of the building. Through digital means, feedback is provided to the building information model to form a sustainable feedback mechanism. The actual operation data of the building (such as energy consumption, equipment status, environmental data, etc.) can be connected with the BIM model to provide real-time feedback on the building operation status to ensure the consistency between the model and the actual situation.

[0042] It is understandable that through the combination of field surveys and 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 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, thereby improving the quality of building information.

[0043] 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: S21: defining the content of the building elements to be collected, so as to obtain the element content standard and element evaluation standard of each building element; wherein the element content standard is used to describe the content form contained in the building element, and the element evaluation standard is used to describe the information format standard that needs to be converted before the content form of the building element is converted into the building information model; S22: collecting corresponding data of the target building according to the element content standard of the building element, so as 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; 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.

[0044] 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. contained in the building elements. 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 format that conforms to the 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.

[0045] 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.

[0046] 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.

[0047] It is understandable that by standardizing the definition of building elements, the comprehensiveness and accuracy of the collected data can be ensured. After the content and evaluation criteria of each building element are clarified, errors and omissions in data collection can be effectively reduced, and the efficiency and quality of data collection can be improved. After evaluation and formatting, the data can be seamlessly imported into the BIM system to ensure the consistency between the BIM model and the actual building data. The standardized processing of data also enables the BIM system to better manage all information of the building.

[0048] 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: S41: pre-planning the information items that need to be monitored in real time in the target building, and analyzing the project monitoring position of each information item according to the building information model to obtain the project monitoring position of each information item corresponding to the target building; wherein the information items include temperature information, smoke information and water pressure information; 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 of the target building corresponding to the respective information items; S43: Pre-planning and analyzing the position where visual information collection is required in the target building according to the building information model to obtain the visual information collection position of the target building; 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, so as to obtain visual information of the target building; 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.

[0049] Specifically, determine which information items need to be monitored in real time and develop a monitoring plan for them. The monitored information items include: temperature information: monitor the temperature inside the building to ensure comfort and safe operation of equipment, smoke information: monitor the risk of fire and detect smoke in time, water pressure information: monitor the water pressure changes in the water pipe network to prevent pipe damage or leakage.

[0050] More specifically, the building's usage needs and safety requirements determine which information items need to be monitored in real time, and appropriate sensor monitoring items are selected based on the building's functions and uses. Common choices include temperature and humidity, smoke detection, water pressure, power consumption, etc.

[0051] More specifically, the building information model is used to analyze the specific locations that need to be monitored inside the building, and reasonable planning is carried out. BIM technology is used to analyze the best monitoring locations for each information item in the target building. For example: temperature information usually needs to be monitored in multiple areas of the building, especially in key locations of the HVAC system (heating, ventilation and air conditioning system); smoke detectors are usually placed in high-risk areas such as kitchens, electrical equipment rooms, equipment rooms, etc.; water pressure information needs to be monitored at key nodes of the water pipe system, such as pump rooms, pipe junctions, etc.

[0052] More specifically, the data in the BIM model (such as room size, purpose, building structure, etc.) is used to determine the best monitoring location for each information item, and sensor groups are set up in the building according to the determined locations to collect data on information items such as temperature, smoke and water pressure in real time.

[0053] 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 at 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 curve, smoke concentration index, 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.

[0054] 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.

[0055] More specifically, according to the preset visual information collection position, AR equipment is set up to obtain real-time visual information of the building, and visual display is performed through augmented reality technology, and AR equipment is deployed at the position determined by BIM model analysis. These devices include but are not limited to: AR head display (such as Microsoft HoloLens, Magic Leap, etc.): used for visual data display on site, AR glasses or mobile devices: convenient for staff to conduct inspections, maintenance and operations on site, AR cameras and sensors: work together with the sensor group in the building to realize real-time linkage of data and visual information.

[0056] More specifically, AR devices can be used to obtain visual data of the construction site in real time. These data may include: Real-time display of building structure layers: combining the building model in BIM with the actual environment to display real-time information such as equipment, pipelines, walls, etc. Facility status display: superimposing real-time status information in the field of view of the equipment, such as equipment failure, temperature abnormality, smoke alarm, etc. Augmented reality visualization: AR devices combine real-time monitoring data with building models to present an augmented reality effect. Through AR devices, staff can see the actual situation of the building and the corresponding sensor monitoring information.

[0057] 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 each area 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, showing 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, and help staff locate the problem area and provide solutions or guidance.

[0058] 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 abnormalities 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., and provide 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, reducing the workload of manual inspections and improving operational management efficiency. Combining the real-time monitoring information of the building with AR technology can enable staff to perform facility maintenance and emergency response more accurately, reducing misoperation and delays. 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.

[0059] Preferably, the step of analyzing the target building according to the real-time monitoring model to obtain the actual characteristic distribution of the elements of the target building comprises: 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; S612: Analyzing the correlation degree of the influence of each building element according to the monitoring information change characteristics, so as to obtain the element correlation change characteristics of each building element fed back by the monitoring information change characteristics; wherein the element correlation change characteristics include the information change part of the monitoring information change characteristics associated with the building element; 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; S614: performing a simulation analysis of element degradation on the building element according to the acquisition completion time of the building element, so as to obtain the element degradation probability distribution of the building element at the current moment; wherein the element degradation probability distribution includes several degradation degrees of the building element and degradation probabilities corresponding to various degradation degrees; S615: performing confidence processing on the element degradation probability distribution according to the element correlation change characteristics of the building element to obtain the degradation actual situation characteristics of the building element; wherein the degradation actual situation characteristics are used to describe the real-time status of the building element in the target building; S616: Combining the actual degradation characteristics of each of the building elements to obtain the actual characteristic distribution of the elements of the target building.

[0060] Specifically, the characteristics of various monitoring information in the real-time monitoring model that change over time are analyzed to reveal the health status and change trends of each element of the target building. The monitoring information in the real-time monitoring model (such as temperature, humidity, smoke concentration, water pressure, etc.) is analyzed in time series to find out the change patterns of monitoring data in different time periods. By analyzing the change patterns of these monitoring information over time, the working status of building elements and their periodic changes can be identified. For example, some facilities may have seasonal changes (such as HVAC systems), while other equipment may have non-periodic changes based on the frequency of use, load or environmental changes. Through the above analysis, the change characteristics of monitoring information, such as fluctuation amplitude, change trend, periodic pattern, etc., are extracted to provide data support for subsequent analysis.

[0061] More specifically, according to the changing characteristics of monitoring information, the mutual influence between different building elements is analyzed, and the changes of which building elements have the greatest impact on other elements are identified. Through the changing characteristics of monitoring data, the relationship model between various building elements is established. Through statistical methods (such as correlation analysis, regression analysis, etc.), the degree of correlation between various elements is calculated. For example, temperature changes may be closely related to the operating status of air-conditioning systems, heating systems, and power systems, while changes in smoke concentration have a high correlation with the operation of fire protection systems and air circulation systems. According to the changing characteristics of monitoring information and the degree of correlation between building elements, it is analyzed which changes in elements have the greatest impact on other elements in the building, as well as the change patterns of these impacts. For example, changes in temperature may affect the load of the HVAC system, but may also affect power consumption through changes in heat load.

[0062] More specifically, according to the collection time of the monitoring system, the collection completion time of each building element is analyzed, and the integrity and timeliness of its data are evaluated, and the collection time information of each monitoring point is extracted from the real-time monitoring model. The monitoring time can include the time span from the start of the system collection to the current moment. According to the monitoring time, the collection completion time of each building element is analyzed. This can be judged by the update timestamp of the monitoring data, and the timeliness and frequency of data collection are evaluated. For example, some systems may collect data in real time (such as temperature and humidity monitoring), while other systems may collect data periodically (such as regular inspection data, equipment operation status, etc.). According to the collection completion time of the monitoring data, analyze which building elements have the latest monitoring data and which may be lagging, thereby affecting the subsequent degradation analysis.

[0063] More specifically, based on the collection time of each building element, the degradation trend of each element is simulated and analyzed, and its degradation probability distribution at the current moment is evaluated. The degradation process of each building element is analyzed using the existing equipment maintenance data, life prediction model and collected real-time monitoring information. For example: based on temperature fluctuations and operating time, the degradation process of the air-conditioning system is simulated, and according to the changes in water pressure, the wear, corrosion or leakage risks of the pipeline system are simulated.

[0064] More specifically, the model simulates the degradation trend of each building element and obtains the degradation probability distribution of each element at the current moment, including the probabilities corresponding to various degrees of degradation (such as mild degradation, moderate degradation, severe degradation, etc.). For example, the degradation of an air-conditioning system may have a 30% probability of mild degradation, a 50% probability of moderate degradation, and a 20% probability of severe degradation.

[0065] More specifically, according to the changing characteristics of element correlations, the degradation probability distribution of building elements is processed with confidence 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.

[0066] 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 increases. Confidence processing will adjust the degradation probability distribution and increase the confidence that degradation has occurred.

[0067] More specifically, through the degradation probability distribution after confidence processing, the actual degradation characteristics of each building element can be obtained, describing the most likely health state of the element at the current moment. This provides building operators with more accurate equipment status data.

[0068] 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, and the overall health status of the building is comprehensively evaluated. The actual degradation characteristics of each building element (including the degree of degradation of each element and its corresponding probability) are combined to form a comprehensive element actual characteristic distribution of the target building. For example, the degradation status of multiple elements such as temperature, humidity, power system, pipeline, fire-fighting equipment, etc. will jointly affect the overall operation of the building.

[0069] More specifically, by analyzing the actual characteristic distribution of elements, we can understand the overall health status of the target building at the current moment, identify which elements are at higher risk of degradation and which are in a healthy state. Based on this analysis, building managers can adjust operation strategies in a targeted manner, perform maintenance, repair or replace equipment in advance, thereby reducing equipment failure rates and improving the long-term sustainability of the building.

[0070] 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: 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; S622: Substituting the actual feature distribution of the elements into the real-time monitoring model to obtain an actual model of the elements, and performing several types of potential risk analysis on the target building according to the actual model of the elements to obtain several potential risk features in the target building; S623: simulating the dangerous conditions of each of the potential risk features according to the actual model of the element, so as to obtain the simulated dangerous conditions of the target building corresponding to each of the potential risk features; 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; S625: evaluating the safety index of each specific location of the element real-life model according to each of the simulated danger conditions and each of the emergency response plans, so as to obtain the safety index of each specific location of the element real-life model; S626: Integrate the safety index of each specific location of the element real-time model to obtain the building safety feature distribution of the target building.

[0071] 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 (such as structure, equipment, facilities, environment, etc.) of the building, 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.

[0072] More specifically, the acquired real-time characteristic data of the elements are substituted into the real-time monitoring model to generate a "real-time element model" to provide a basis for the analysis of potential risks. According to the real-time monitoring data, the real-time characteristics of each element are used as input to build the real-time element model. This model can simulate and predict the current and future status of different elements, such as equipment health, structural stress, environmental changes, etc. The real-time element model is a dynamic model that can be updated in real time according to the changes in real-time monitoring data to ensure accurate reflection of the status of each element of the building.

[0073] More specifically, based on the actual model of the elements, the potential safety risks that may exist in the target building are analyzed, and the risk types and risk characteristics are identified. By analyzing the actual model of the elements, the potential risks that may exist in each element of the building are identified. For example: structural risks: such as cracks, settlement, tilt, etc. of the building structure, fire risks: such as electrical failures, temperature anomalies, smoke concentration, etc., flood risks: such as water pipe leakage, drainage system failure, etc., environmental risks: such as gas leakage, air quality degradation, etc., risk characteristic analysis: Based on the data of the actual model of the elements, the probability of occurrence, scope of impact and potential consequences of each risk are analyzed. For example, the power system may have the risk of short circuit or overload, and the HVAC system may cause temperature instability and equipment damage. The identified risks are divided into categories and their characteristics are analyzed, such as fire risk, structural instability risk, equipment failure risk, etc.

[0074] More specifically, based on the actual model of the elements, various potential risks are simulated, the specific scenarios when the risks occur are predicted, and different types of dangerous situations are simulated according to the risk characteristics. For example, for the overload risk of the power system, 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 be caused when the risks occur. According to different risk categories, the development process of dangerous situations under multiple different scenarios is simulated to ensure a comprehensive prediction of various potential risks.

[0075] More specifically, according to the results of the dangerous situation simulation, formulate corresponding emergency plans, and simulate the execution effect of the plans to ensure a rapid response when the dangerous situation occurs. According to the simulated conditions of various dangerous situations, formulate corresponding emergency plans, 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 dangerous conditions, test the effectiveness of various emergency plans, analyze factors such as the time for plan execution, resource requirements, and personnel collaboration; according to the simulation results, optimize the emergency plan to improve the emergency response speed and the feasibility of the plan.

[0076] More specifically, based on the simulated danger 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 danger conditions and the corresponding emergency plans. Safety index assessment usually considers 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 the safety of the building; Historical data: the occurrence of similar incidents in history and the effect of handling. Location safety index: According to the different locations in the building (such as floors, areas, equipment, etc.), the risk exposure, emergency response capabilities, etc. are evaluated to obtain the safety index of each location. Risk tolerance: According to the structural characteristics and use of the building, the tolerance threshold of the safety index is set to ensure that the overall safety level of the building is within an acceptable range.

[0077] More specifically, the safety index of each location is integrated to obtain the overall safety feature distribution of the building, thereby providing decision support for building management. The safety index of each location in the building is weighted and integrated to obtain a comprehensive building safety feature distribution. These safety indexes 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 indexes, 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.

[0078] Preferably, the step of evaluating the safety index of each specific location of the element real-life model according to each of the danger simulation conditions and each of the danger response plans to obtain the safety index of each specific location of the element real-life model includes: S6251: Analyzing the probability of occurrence of danger and the degree of danger of danger at each specific location of the element actual model according to each of the danger simulation conditions, so as to obtain a negative safety index at each specific location of the element actual model; 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 at each specific location of the element real-time model; S6253: Combine the negative safety index and the positive safety index of each specific location of the actual model of the element to obtain the safety index of each specific location of the target building.

[0079] Specifically, the negative impact of specific locations in the target building when potential risks occur, that is, the probability and severity of the dangerous situation, is evaluated to obtain the negative safety index of each location. 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, for example, the probability of electrical system overload and the possibility of crack expansion in the building structure.

[0080] More specifically, based on the simulation results, the severity of each hazard is evaluated, taking into account the scope of impact, degree of damage and consequences when the hazard occurs. For example, the speed of smoke spread and degree of structural damage when a fire occurs. Based on the probability and degree of danger of each location, the negative safety index of the location is calculated.

[0081] More specifically, the timeliness and success rate of emergency response in specific locations of the target building when a dangerous situation occurs are evaluated to obtain the positive safety index of each location. For each potential risk, the corresponding emergency plan is evaluated, including the emergency response time and the emergency response success rate. According to 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 fighting, evacuation, alarm, etc.), the timeliness of the emergency response is calculated.

[0082] 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 startup, the success rate of automatic power system shut-off, etc. Positive safety index: Based on the timeliness and success rate of emergency response at each location, the positive 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.

[0083] 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 weighted 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.

[0084] More specifically, the final comprehensive safety index can be analyzed by different dimensions such as area, floor, equipment, etc., 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 the improvement of emergency plans.

[0085] It is understandable that by combining potential risks and emergency response capabilities, it is possible to comprehensively and dynamically evaluate 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 included in the evaluation system to ensure that the building has sufficient emergency capabilities to effectively deal with risks when they occur, thereby 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.

[0086] Preferably, it also includes: searching and locating the fire-fighting facilities within the surrounding range of the building information model through the city information platform to obtain the positioning information of the surrounding fire-fighting facilities of the building information model, converting and processing the positioning information to obtain a rescue unit, analyzing the rescue path and its movement efficiency of the rescue unit and the building information model according to the city information platform to obtain the rescue path and its movement efficiency between the rescue unit and the building information model, and correcting the building safety feature distribution of the target building according to the rescue path and its movement efficiency to obtain the 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 under the rescue of the fire rescue facility; The rescue safety feature distribution is inspected and evaluated according to preset standards to determine a safety inspection plan for the target building.

[0087] Specifically, the city information platform is used to comprehensively search and locate the fire-fighting facilities around the target building, and the specific location of the fire-fighting facilities is obtained to provide 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.

[0088] More specifically, the location of fire-fighting facilities around the building, including information such as fire stations, fire water sources, and fire-fighting equipment, is obtained through the urban information platform. 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 facilities are located, the location information of the fire-fighting facilities related to the building information model is generated, including distance, direction, etc., for subsequent path analysis.

[0089] 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 fire-fighting facilities and the surrounding rescue resources, the available fire rescue units are determined, such as fire trucks, ambulances, fire-fighting equipment, etc.

[0090] More specifically, based on the data of the building information model and the urban information platform, the shortest path of the rescue unit from the firefighting facilities to the target building is calculated. Path analysis can calculate the optimal rescue path based on a variety of algorithms (such as Dijkstra algorithm, A* algorithm, etc.). In addition to calculating the shortest path, the mobility efficiency of the rescue unit, such as traffic conditions, road restrictions, traffic signals and other factors, needs to be considered. The mobility efficiency of the rescue unit is analyzed using real-time traffic data, urban traffic models and the performance of the rescue unit (such as the maximum speed of the fire truck, the degree of traffic congestion, etc.), and the actual time for the rescue unit to arrive at the target building is obtained. The rescue path from the firefighting facilities to the target building and the corresponding mobility efficiency information are generated to provide a basis for the subsequent correction of the safety feature distribution.

[0091] More specifically, after understanding the path and mobility efficiency of the rescue unit, the distribution of building safety features is corrected to reflect the safety level of each location of the building under the support of fire rescue. According to the safety data of the building information model, the preliminary safety feature distribution of the target building is first generated. These features include building structural safety, fire protection facilities, escape route design, fire risk area, etc. The building safety features are corrected using the rescue path and rescue efficiency analysis results. For example: Rapid rescue area correction: If some areas are close to the rescue unit and the path is unobstructed, the safety of these areas can be relatively high, and the safety features are improved. Rescue delay area correction: If some areas have a long rescue time and complex paths, the safety of these areas needs to be reduced. The corrected safety features reflect the relatively high risk of the area. Corrected safety features: According to the corrected results, the safety features of each location in the building are updated to form a new "rescue safety feature distribution map". This map will show the changes in safety at various locations in the building after receiving fire rescue.

[0092] More specifically, according to the revised rescue safety feature distribution, the safety status of the target building is evaluated, and a corresponding safety inspection and maintenance plan is formulated. According to the building's safety specifications, fire standards, risk assessment requirements, etc., a set of preset standards is set to evaluate the compliance of the rescue safety feature distribution. For example, it is stipulated that the safety index of each area needs to reach a certain standard value, or certain high-risk areas need special attention. According to the revised rescue safety feature distribution and preset standards, the safety status of the building is evaluated. During the evaluation, various technical means (such as risk analysis models, Monte Carlo simulations, etc.) can be used to conduct a comprehensive inspection of the rescue safety features of the building. Through safety assessment, areas with low safety indexes or poor rescue efficiency can be identified. These areas may need to be focused on for maintenance. According to the evaluation results, specific safety inspection and maintenance plans are formulated for high-risk areas. For example, fire-fighting equipment can be added, escape routes can be improved, and the layout of the fire-fighting system can be optimized. Through evaluation and correction, the safety inspection and maintenance plan is optimized, and it is adjusted and optimized in the subsequent maintenance process of the building to ensure long-term safety management.

[0093] 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 units 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 when a disaster occurs.
