Description

Technical Field

[0001] The present invention relates to the field of safety monitoring software design, and in particular to a structural safety online monitoring system and method. Background Art

[0002] Structural safety monitoring refers to collecting monitoring data corresponding to the monitored object by installing corresponding monitoring sensors, and realizing safety monitoring of the monitored object by analyzing and processing the monitoring data.

[0003] Existing structural safety monitoring systems and monitoring methods usually select monitoring points on the monitored object based on specifications and expert experience, and then install monitoring sensors to monitor the structural safety of the monitored object.

[0004] In order to achieve safety monitoring in this monitoring method, monitoring points are usually deployed over a large area, basically covering the entire monitoring object, requiring the use of many monitoring sensors, and complex installation and wiring of monitoring sensors. In addition, there are a large number of monitoring data sent back by monitoring sensors in the later stage, which puts great pressure on monitoring data analysis and processing, and high equipment operation and maintenance costs. Therefore, the current structural safety monitoring system and method have the problem of unreasonable monitoring point settings.

[0005] In addition, after the monitoring sensors of the existing structural safety monitoring systems and methods collect monitoring data from monitoring objects under different conditions, the data are uniformly transmitted back to the same processing background. The processing background uses the same preset safety processing algorithm or model to uniformly process the monitoring data. When the same safety processing algorithm or model is used to uniformly process the monitoring data of different monitoring objects under different conditions, it is easy to lead to inaccurate safety monitoring results. Summary of the invention

[0006] The purpose of the present invention is to solve the problems of unreasonable monitoring point settings and inaccurate safety monitoring result judgment in existing structural safety monitoring systems and methods.

[0007] To achieve the above object, the present invention provides a structural safety online monitoring system, the system comprising:

[0008] A first camera acquisition module, wherein the system is connected to a camera device in the first camera acquisition module, the first camera acquisition module is used to capture and record a preset location to obtain a monitoring video, and the first camera acquisition module is used to play back the monitoring video; the first camera acquisition module is also used to acquire an appearance image of the building to be monitored, obtain a first image, analyze the first image, and obtain appearance information of the building to be monitored;

[0009] The second basic information collection module is used to collect construction information of the building to be monitored; the second basic information collection module is also used to upload basic information and actual on-site pictures of the building to be monitored, and archive the basic information of the building as a basis for subsequent monitoring data analysis and processing;

[0010] The third project is a geographic information acquisition module, which is used to obtain the geographic location information of the building to be monitored;

[0011] The fourth data acquisition module is used to obtain the foundation soil information of the building to be monitored through the equipment networking module as data support for subsequent data analysis;

[0012] The fifth building internal feature access module is used for the three-dimensional model of the internal structural feature information of the building to be monitored, so that users can intuitively view the internal status of the structure;

[0013] An analysis module, used for training a monitoring point determination model and a safety monitoring model based on the appearance information, construction information, geographic location information, foundation soil information and internal structure feature information;

[0014] A monitoring module, for obtaining appearance information, construction information, geographic location information, foundation soil information and internal structure characteristic information of the building to be monitored, obtaining monitoring point information of the building to be monitored based on the appearance information, construction information, geographic location information, foundation soil information and internal structure characteristic information of the building to be monitored and the monitoring point determination model, and for installing monitoring equipment at positions corresponding to the monitoring point information to collect and obtain monitoring information;

[0015] A processing module is used to obtain the safety monitoring result of the building to be monitored based on the monitoring information and the safety monitoring model analysis and processing.

[0016] Among them, the present invention is different from the traditional technology in one aspect: the monitoring points in the present invention are not determined by experience or direct uniform coverage of the monitoring target, but are determined by a monitoring point determination model combined with the information of the building to be monitored itself. The monitoring points are determined based on the appearance information, construction information, geographical location information, foundation soil information and internal structure characteristic information of the building to be monitored itself. On the one hand, the appearance information, construction information, geographical location information, foundation soil information and internal structure characteristic information that affect and reflect the safety of the building are taken into account. Through this information, the specific location of the monitoring point of the building can be accurately determined; on the other hand, the monitoring points are determined by a monitoring point determination model obtained through training based on historical data. In this way, the monitoring point determination efficiency is high, the monitoring points can be quickly obtained, and The monitoring point determination model obtained through training with historical training data can accurately obtain monitoring points, and does not need to adopt a method of evenly covering and laying monitoring points, which can save the number of monitoring sensors and reduce the amount of data for later processing of monitoring data. Therefore, the monitoring point determination model obtained through training by the present invention taking into account appearance information, construction information, geographic location information, foundation soil information and internal structure feature information can quickly and accurately obtain monitoring points, overcoming the problems of traditional manual arrangement of sensors based on experience, even arrangement of sensors, low efficiency and high cost, and large amount of data in the later stage, and the monitoring points are accurate, and the safety monitoring of the monitored building can be accurately performed; and the safety monitoring model obtained through training based on the above information can accurately judge whether the monitored building is safe and obtain accurate safety monitoring results.

[0017] Among them, the present invention collects and obtains appearance information, construction information, geographical location information, foundation soil information and internal structure characteristic information through the first to fifth collection modules respectively. The purpose of collecting this information is: through the appearance information, it can be judged whether the appearance of the building is damaged or normal, and then whether the building has safety hazards from the appearance; through the construction information, the construction year, building type, construction technology and building materials of the building can be obtained. The construction year can reflect the actual age of the building. Through the actual age of the building, it can be judged whether the building is within the safe service life range. Different building types, construction technologies and building materials have different resistance to disasters and dangers. Therefore, different building types, construction technologies and building materials reflect different safety monitoring influencing factors; geographical location information reflects the actual location of the building, such as whether it is located in an earthquake zone, etc. Different geographical locations have different safety requirements for buildings. Therefore, geographical location also needs to be considered in the safety monitoring influencing factors of the building; foundation soil is the load-bearing base of the building, which also has an impact on the safety of the building. Therefore, the building safety monitoring also needs to take the foundation soil information into consideration; the internal structure characteristic information is information that reflects whether the internal structure of the building is safe, which also has an impact on the safety of the building. Therefore, the building safety monitoring also needs to take the foundation soil information into consideration.

[0018] By collecting all the above-mentioned information reflecting the safety of the building to form training samples, it is possible to train a monitoring point determination model and a safety monitoring model that can accurately reflect the monitoring points and building safety monitoring results.

[0019] Among them, in the actual monitoring process, the monitoring point information of the building to be monitored is obtained according to the real-time information of the building to be monitored and the monitoring point determination model, and then the monitoring equipment is installed at the corresponding position of the determined monitoring point information to collect the monitoring information; then the processing module can be used to analyze and process based on the monitoring information and the safety monitoring model to obtain the safety monitoring results of the building to be monitored.

[0020] The security monitoring model is obtained as follows:

[0021] Collect and obtain historical data of several buildings, including: appearance information, construction information, geographical location information, foundation soil information and internal structural characteristics information of each building;

[0022] Construct architectural models corresponding to each building;

[0023] Conduct safety tests on building models to obtain safety test data;

[0024] obtaining first sample data for each building based on historical data and safety test data for each building;

[0025] Constructing a first training set based on first sample data of a plurality of buildings;

[0026] The first prediction model is trained using the first training set to obtain a safety monitoring model.

[0027] Among them, a high-quality training set can be obtained through rich historical data, so that the prediction ability of the model is guaranteed and the prediction results are accurate. Since it is necessary to conduct safety tests on buildings, it is necessary to have a building model corresponding to each building, and then conduct safety tests on the building model to obtain safety test data, such as critical data when a building has a safety accident or structural safety, etc. A first training set is constructed through the historical data and safety test data of each building, and then the first prediction model is trained with the first training set to obtain a safety monitoring model, that is, a safety monitoring model with the ability to monitor building safety is obtained. In subsequent use, only the building's appearance information, construction information, geographic location information, foundation soil information and internal structure feature information need to be input to obtain the building's safety monitoring results. The above method can be used to obtain a safety monitoring model that takes into account many safety factors (appearance information, construction information, geographic location information, foundation soil information and internal structure feature information), and the safety monitoring model can be used to quickly and accurately obtain the building's safety monitoring results.

[0028] The monitoring point determination model is obtained in the following manner:

[0029] Collect and obtain historical data of several buildings, including: appearance information, construction information, geographical location information, foundation soil information and internal structural characteristics information of each building;

[0030] Construct architectural models corresponding to each building;

[0031] Conduct safety accident tests on building models to obtain accident point information corresponding to safety accidents;

[0032] Obtain second sample data for each building based on historical data and accident location information of each building;

[0033] constructing a second training set based on second sample data of the plurality of buildings;

[0034] The second prediction model is trained using the second training set to obtain a monitoring point determination model.

[0035] Among them, the present invention collects historical data that can reflect the monitoring points of buildings, and conducts safety accident tests on buildings by constructing building models to obtain accident point information corresponding to safety accidents, and then uses the historical data and accident point information of each building to obtain second sample data of each building. The monitoring points of the building can be accurately reflected through the second sample data, and then the second sample data is used to construct a second training set to train and obtain a monitoring point determination model. The monitoring points of the building can be quickly, accurately and comprehensively obtained through the monitoring point determination model.

[0036] The monitoring device includes a plurality of monitoring terminals, each of which corresponds to a number and a monitoring point. The system also includes a management module, which is used to:

[0037] Obtain time information of the area where the building to be monitored is located;

[0038] Obtain public opinion information of the building to be monitored;

[0039] Obtaining identity attribute information of the building to be monitored;

[0040] Generate an activation plan for the monitoring device in a future preset time period based on the time information, the public opinion information and the identity attribute information, the activation plan including: a number of continuous states of each monitoring sensor in the future time period and the duration of each state, the state being an on state or an off state;

[0041] The opening and closing of each monitoring sensor is controlled based on the opening scheme.

[0042] Among them, the applicant's research found that the monitoring sensors of the current security monitoring system are all in a normally-on state, which consumes a lot of energy and transmits a large amount of data, resulting in high pressure on background data processing and easily reducing the service life of the sensors. The security monitoring is not flexibly matched with the actual use of the building. In order to solve this problem, the present invention designs a management module, which can control the opening and closing of each monitoring sensor in the system and the opening time, so that the monitoring terminal is turned on when it is needed and turned off when it is not needed, thereby reducing the amount of data transmitted and the usage time, reducing the pressure on background data processing, reducing energy consumption, and extending the service life of the terminal. Specifically, the time information of the area where the building to be monitored is located, the public opinion information of the building to be monitored, and the identity attribute information of the building to be monitored are obtained to generate an opening plan for the monitoring device within a preset time period in the future, wherein the time information of the area where the building to be monitored is located is Different time information may lead to different safety monitoring results for buildings. For example, during the tourist season or weekends, there are many tourists at tourist attractions, and the pressure on the buildings is high, so more terminals need to be opened and the opening time needs to be extended. During weekdays other than weekends or tourist seasons, the pressure on the buildings is small, so some terminals can be closed and the opening time can be reduced. During the flood season, more terminals need to be opened for dams or bridges, and the opening time needs to be extended. During the non-flood season, some terminals can be closed and the opening time can be reduced. For example, the Internet is well developed and public opinion spreads quickly. Public opinion may attract a large number of vehicles or people, which puts greater pressure on buildings or bridges. Therefore, when public opinion involves buildings, more terminals need to be opened and the opening time needs to be extended. The identity attribute information of the buildings to be monitored can reflect the importance of the buildings to be monitored, and the number and duration of terminal opening can be controlled based on different levels of importance.

[0043] The monitoring device includes several monitoring terminals, each of which includes:

[0044] An identification end, the identification end is used to be attached to a corresponding monitoring point of the building to be monitored;

[0045] The acquisition end is used to acquire image information of the marking end and obtain displacement information of the marking end based on image information analysis.

[0046] Among them, the traditional monitoring terminal is to drill holes or bury or cast the monitoring terminal on the building, and then use the monitoring terminal to form an integrated whole with the building, and then monitor and obtain the deformation data of the building. However, this monitoring method requires drilling holes or construction on the building, which is not suitable for monitoring ancient buildings. Since the ancient buildings are very old, most of them have safety hazards and need to be monitored. The traditional installation method of safety monitoring terminals is not suitable for ancient buildings and will cause damage to the ancient buildings. Therefore, the present invention designs a monitoring terminal suitable for ancient buildings, by fitting the identification terminal at the monitoring point of the ancient building, and then collecting the image information of the identification terminal, and finally obtaining the displacement information of the identification terminal based on the image information analysis, the damage to the ancient building is reduced by the fitting method, and the displacement information can be obtained by replacing the traditional sensor terminal through image analysis.

[0047] Wherein, the building to be monitored is a bridge, and the system further includes an interception module, which is used to activate the interception function when the safety monitoring result of the bridge shows that the bridge safety is abnormal, and intercept the two-way traffic targets on the road corresponding to the bridge.

[0048] Among them, although the existing monitoring systems all have safety monitoring functions and can issue alarms when safety accidents occur in buildings or before accidents occur, in some special cases, although the alarm is issued, major safety accidents may still occur. For example, after a bridge collapses, the safety monitoring system has issued an alarm, and the background and security maintenance personnel have received the alarm notification, but vehicles traveling on both sides of the bridge will continue to drive towards the collapsed bridge in the case of poor visibility, eventually leading to a more serious safety accident. Therefore, in order to solve this problem, the interception module designed in the present invention can activate the interception function after a safety accident occurs in the bridge, intercept the two-way traffic targets of the road corresponding to the bridge, reduce the probability of vehicles continuing to drive towards the bridge, reduce the probability of subsequent safety accidents, and further improve the actual safety in practical applications based on the alarm.

[0049] Among them, the system also includes a sixth acquisition module, which is used to collect the monitoring image of the first position corresponding to the accident point information of the building to be monitored, analyze the monitoring image to determine whether there is any behavior that destroys the building structure corresponding to the first position, and if so, issue an alarm.

[0050] Among them, the sixth acquisition module can be used to acquire the monitoring image of the first position corresponding to the accident point information. By analyzing the monitoring image, it can be determined whether there is any behavior that damages the building structure corresponding to the first position. Since the first position is the position corresponding to the accident point information and is a key point for the safety of the building, it needs to be monitored. The traditional monitoring method is to issue an alarm when an abnormality has occurred, and the damage to the building is irreversible. Therefore, in order to achieve the protection of key monitoring points and fundamentally realize the safety protection of the building, the sixth acquisition module is designed to monitor the situation of the first position in real time through image analysis, and issue an alarm when damage occurs, which can effectively prevent it before substantial damage is caused to the building.

[0051] The system further includes an analysis module, which is used to analyze the status of the monitoring device and issue an alarm if the analysis result shows that the status of the monitoring device is abnormal. The analysis module can be used to analyze the status of the monitoring device and issue an alarm when the monitoring device is abnormal, offline, or fails, so as to facilitate the rapid maintenance and replacement of the monitoring device and ensure the normal safety monitoring of the monitored building.

[0052] The system further includes a display module for displaying the real scene information of the building to be monitored based on the collected image information, and for displaying the three-dimensional model information of the building to be monitored based on the BIM model. The display module can be used to display the real scene information and the three-dimensional model information of the building to be monitored.

[0053] The present invention also provides a structural safety online monitoring method based on the structural safety online monitoring system, the method comprising:

[0054] Collecting an appearance image of the building to be monitored to obtain a first image, and analyzing the first image to obtain appearance information of the building to be monitored;

[0055] Collect and obtain the construction information, geographical location information, foundation soil information and internal structure characteristics information of the building to be monitored;

[0056] Based on the appearance information, construction information, geographic location information, foundation soil information and internal structure feature information, a monitoring point determination model is obtained by training and a safety monitoring model is obtained by training;

[0057] Obtain appearance information, construction information, geographic location information, foundation soil information, and internal structure characteristic information of the building to be monitored; based on the appearance information, construction information, geographic location information, foundation soil information, and internal structure characteristic information of the building to be monitored and the monitoring point determination model, obtain monitoring point information of the building to be monitored; and install monitoring equipment at positions corresponding to the monitoring point information to collect and obtain monitoring information;

[0058] The safety monitoring result of the building to be monitored is obtained based on the monitoring information and the safety monitoring model analysis and processing.

[0059] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0060] The monitoring point determination efficiency of the present invention is high, the monitoring points can be obtained quickly, the number of monitoring terminals can be saved and the amount of data for later processing of monitoring data can be reduced. Moreover, the monitoring points are accurate and can accurately monitor the safety of the buildings to be monitored; it can accurately judge whether the buildings to be monitored are safe and obtain accurate safety monitoring results.

[0070] Embodiment 1;

[0071] Please refer to Figure 1 , Figure 1 The figure is a schematic diagram of the composition of a structural safety online monitoring system. The present invention provides a structural safety online monitoring system, the system comprising:

[0072] A first camera acquisition module, the system accesses a camera device in the first camera acquisition module, the first camera acquisition module is used to capture and record a preset part to obtain a monitoring video, and the first camera acquisition module is used to play back the monitoring video; the first camera acquisition module is also used to capture the appearance image of the building to be monitored, obtain a first image, analyze the first image, and obtain the appearance information of the building to be monitored; wherein the preset part can be a pre-set part or a part of key concern for monitoring, and the specific position can be adjusted according to actual needs. In actual application, the direction of the camera can be adjusted to achieve the capture of the preset part or the capture of the camera set separately. The first camera acquisition module is provided with a data storage device and a data processor as well as a video playback and processing software, which can play back the monitoring video, so that the security inspection personnel can play back and view it;

[0073] The second basic information collection module is used to collect construction information of the building to be monitored; the second basic information collection module is also used to upload basic information of the building to be monitored and actual on-site pictures; the second basic information collection module is provided with a communication module that can use mobile data or Beidou communication to transmit data;

[0074] The third project is a geographic information acquisition module, which is used to obtain the geographic location information of the building to be monitored;

[0075] The fourth data acquisition module is used to obtain the foundation soil information of the building to be monitored through the device networking module;

[0076] The fifth building internal feature access module supports access to the internal structural feature information of the building to be monitored and other three-dimensional models to facilitate users to intuitively view the internal status of the structure;

[0077] An analysis module, used for training a monitoring point determination model and a safety monitoring model based on the appearance information, construction information, geographic location information, foundation soil information and internal structure feature information;

[0078] A monitoring module, for obtaining appearance information, construction information, geographic location information, foundation soil information and internal structure characteristic information of the building to be monitored, obtaining monitoring point information of the building to be monitored based on the appearance information, construction information, geographic location information, foundation soil information and internal structure characteristic information of the building to be monitored and the monitoring point determination model, and for installing monitoring equipment at positions corresponding to the monitoring point information to collect and obtain monitoring information;

[0079] A processing module is used to obtain the safety monitoring result of the building to be monitored based on the monitoring information and the safety monitoring model analysis and processing.

[0080] Among them, in the embodiment of the present invention, for buildings that are generally not very large, the first acquisition module can be a camera or a video camera, and the first image is obtained by shooting with a handheld device. If the size of the building is large, a drone carrying a camera or a video camera can be used to shoot and obtain the first image. After obtaining the first image, the image processing software can be used to analyze and process to obtain the appearance information of the building to be monitored, such as the size information of the building to be monitored can be measured by the size marking module or the size measurement module in the image processing software. The size of the building to be monitored can reflect the safety factors of the building, because larger buildings require stronger structural support and stability to cope with the influence of natural forces such as wind and earthquakes. Therefore, it is necessary to fully consider this factor during safety monitoring to ensure the accuracy of building structure monitoring.

[0081] Among them, in an embodiment of the present invention, the appearance information may include the appearance damage and weathering conditions of the building in addition to the size information of the building. The appearance damage and weathering conditions can reflect whether the appearance of the building is safe. The appearance damage and weathering conditions can be obtained through the appearance detection model. First, several images of buildings with appearance damage or weathering are collected, and then the locations of the appearance damage or weathering are marked in the images. Then, a training image set is obtained, and then the target recognition model is trained. After the training, an appearance detection model with the ability to detect appearance damage and weathering conditions is obtained.

[0082] Among them, the construction information of the building to be monitored can be obtained through a web crawler or a query database after obtaining the identity information of the building to be monitored. The construction information of the building to be monitored may include: the year the building was built, the building type, the construction technology and the building materials used.

[0083] The building's service life can be calculated through the year the building was built and the current real-time time. Then, based on the service life and the rated service life of the building, it can be determined whether the building has corresponding safety hazards. For example, for buildings that were built earlier, it is necessary to strengthen safety monitoring, lower the threshold of safety monitoring, and improve the safety monitoring effect. For buildings that were built later, the safety monitoring requirements can be relaxed.

[0084] Building types include: earth-stone structure, brick-wood structure, brick-concrete structure, reinforced concrete structure and steel structure. Different types of buildings have different pressure bearing capacity, so the type of building needs to be considered during safety monitoring. For example, for brick-wood buildings, it is necessary to strengthen safety monitoring, lower the threshold of safety monitoring, and improve the safety monitoring effect. For steel-structured buildings, the safety monitoring requirements can be relaxed.

[0085] Different building construction techniques can affect the final quality of the building. Complex construction techniques have higher quality but lower efficiency, while simple construction techniques have higher quality communication efficiency. Therefore, different buildings adopt different construction techniques according to actual needs during construction. Therefore, when monitoring the safety of a building, the construction technique used during its construction is also a factor that needs to be considered for safety monitoring. For example, for buildings constructed with a construction technique with a lower safety factor, it is necessary to strengthen safety monitoring, lower the threshold of safety monitoring, and improve the safety monitoring effect. For buildings constructed with a construction technique with a higher safety factor, the safety monitoring requirements can be relaxed.

[0086] Among them, the geographical location information of the buildings to be monitored can be obtained through the positioning module or by querying the geographical location information. Different geographical location information can reflect different safety environment influencing factors. For example, buildings located in earthquake zones or locations with frequent geological activity require strengthened safety monitoring, while buildings in non-earthquake zones or locations with infrequent geological activity can reduce the safety monitoring level.

[0087] Among them, the foundation soil information of the building to be monitored refers to the specific foundation type of the building. For example, the foundation types include natural foundation and artificial foundation. The natural foundation is a natural soil layer. By collecting the soil information of the natural soil layer, its soil information, such as soil type, can be obtained. Through the soil type, the corresponding safety information of this type of foundation can be queried. Artificial foundations need to be reinforced by humans. Common ones include stone chip cushions, sand cushions, mixed ash soil backfill and compaction. Different types of artificial foundations have different strengths and corresponding safety effects. Therefore, it is necessary to collect and obtain the foundation soil information of the building to be monitored, and then combine the specific soil information to obtain the corresponding safety impact. For example, natural foundations require strengthened safety monitoring, and concrete reinforced foundations in artificial foundations can reduce the safety monitoring threshold.

[0088] Among them, the internal structural characteristic information of the building to be monitored; the internal structural characteristic information of the building includes its structural composition, the function of each part and the design requirements. This information can be obtained by querying the design materials or architectural historical document materials of the building to be monitored, or manually inspecting the interior of the building. The specific acquisition method is not specifically limited in the embodiment of the present invention. Different internal structural characteristics of buildings correspond to different safety monitoring requirements. Therefore, different fixed safety monitoring coefficients or requirements can be adopted according to the internal structural characteristics of different buildings in actual applications. The embodiment of the present invention does not specifically limit it.

[0089] Among them, after obtaining appearance information, construction information, geographic location information, foundation soil information and internal structure feature information, a training set is constructed using this information, and then machine learning or artificial intelligence is used to train to obtain a monitoring point determination model and a safety monitoring model. When training the monitoring point determination model, it is necessary to mark the monitoring points in the training set so that the model can learn to obtain the ability to determine the monitoring points. In the safety monitoring model, it is necessary to mark the safe and unsafe situations in the training set so as to train to obtain a safety monitoring model with safety analysis capabilities. The model in the present invention adopts a model commonly used in existing machine learning or artificial intelligence, and the embodiments of the present invention do not make corresponding limitations.

[0090] In this embodiment of the present invention, the security monitoring model is obtained in the following manner:

[0091] Collect and obtain historical data of several buildings, including: appearance information, construction information, geographical location information, foundation soil information and internal structural characteristics information of each building;

[0093] A safety test is performed on the building model to obtain safety test data. For example, the stress test analysis module in the above-mentioned software, or other building model stress test analysis software can be used to obtain safety test data. The safety test data includes the maximum critical stress or displacement or offset or deformation of the building. The specific test data can be adjusted according to actual needs, and the embodiment of the present invention does not make specific limitations.

[0095] Constructing a first training set based on first sample data of a plurality of buildings;

[0096] The first prediction model is trained using the first training set to obtain a safety monitoring model.

[0097] Among them, in the embodiment of the present invention, the monitoring point determination model is obtained in the following manner:

[0099] Constructing a building model corresponding to each building; the building model may be constructed using corresponding building modeling software, such as 3Dmax, Rhino, SketchUp, and Cinema 4D, etc., which is not specifically limited in the embodiment of the present invention;

[0100] Conduct safety accident tests on the building model to obtain the accident point information corresponding to the safety accident; for example, the stress test analysis module in the above software or other building model stress test analysis software can be used to test the building model. When deformation or structural damage occurs during the test, the damaged point or position is observed, and the point or position is the accident point information;
