Description

Technical Field

[0001] The present invention relates to construction safety management technology, and in particular to a method and system for automatically identifying construction safety hazards based on deep learning. Background Art

[0002] As a key pillar of the national economy, the construction industry's development is directly linked to infrastructure development and socioeconomic progress. However, the industry has long faced severe challenges stemming from high risks and high accident rates, making construction site safety management a top priority.

[0003] Construction sites are a remarkably complex and dynamic environment, involving large numbers of people working across multiple sectors, a wide variety of machinery and equipment, densely stacked construction materials, and constantly changing work processes. These intertwined and interdependent factors contribute to the diversity, concealment, and sudden nature of construction safety hazards. Common safety hazards include falls from heights, impacts, mechanical injuries, electric shocks, and collapses. Once these hazards trigger accidents, they often result in serious casualties and property damage.

[0004] Currently, most construction companies still rely on the traditional manual inspection model to identify safety hazards. This model relies primarily on safety managers to conduct regular or irregular inspections of construction sites based on their personal experience and expertise. However, this approach has insurmountable limitations: (1) Low recognition efficiency: Construction sites are usually vast and have scattered work points, making it difficult for safety management personnel to achieve comprehensive coverage in a short period of time. Inspection blind spots and missed inspections are very likely to occur, especially for large-scale buildings or complex work scenarios. The timeliness of manual inspections cannot meet the needs of real-time safety monitoring.

[0005] (2) Identification accuracy is subject to subjective factors: Different managers have different experience reserves and professional levels, and their judgments on the same hidden danger may be inconsistent, making it difficult to ensure the accuracy and reliability of hidden danger identification.

[0006] (3) High labor costs and work intensity: To cover all operating areas, companies need to invest a large amount of manpower, resulting in high management costs. Furthermore, inspectors are often exposed to complex outdoor environments for long periods of time, facing high workloads and prone to fatigue, which further impacts inspection effectiveness.

[0007] These limitations directly lead to low efficiency and accuracy in identifying construction safety hazards, making it difficult to adapt to the refined and intelligent safety management requirements of modern construction. There is an urgent need for an efficient and accurate automatic identification technology to make up for the shortcomings of traditional models. Summary of the Invention

[0029] The present invention aims to provide a method and system for automatically identifying construction safety hazards based on deep learning, improving the efficiency and accuracy of construction safety hazard identification. Its core concept is to achieve automatic identification and early warning of construction safety hazards by building and training a deep learning model. Specifically, historical construction anomaly information and its corresponding causes are collected. Features covering the three time periods before, during, and after the anomaly are extracted, including human behavior characteristics, environmental parameter characteristics, and equipment operation characteristics (information about the equipment itself and its interactions with associated equipment) corresponding to each time period. This is then used to train a pre-set construction anomaly hazard model, enabling it to identify hazards. In practical applications, the human behavior information, equipment operation information, and environmental parameter information to be identified are obtained. This real-time information is processed using the aforementioned features to generate construction precursor data, which is then input into the trained model for identification. If a hazard anomaly is identified, the location of the abnormal area is determined. A three-dimensional construction model is constructed to analyze the distribution of hazards in the area (concentrated or dispersed). A hazard trend curve is generated and future trends are predicted. A hazard coefficient is calculated, and the hazard level is determined based on the anomaly data and cause. When the level meets preset criteria, a hazard warning message containing the anomaly data and cause is generated. In this way, the present invention forms a complete automatic identification system from data collection, model training to real-time identification, risk assessment and early warning.

[0030] In terms of specific implementation, the implementation ideas of the solution of the present invention include: first, by comprehensively acquiring personnel behavior information, equipment operation information (including the operation data of a single device itself and the interactive operation information between related devices) and environmental parameter information, it can completely cover the key elements of the construction site, thereby evaluating the construction status from multiple dimensions such as personnel operation, equipment status, and environmental impact, greatly improving the accuracy of discovering potential hidden dangers and enhancing construction safety.

[0031] At the same time, by collecting historical construction anomaly information and the corresponding anomaly causes, we can extract time period characteristics (i.e., the first time period before the anomaly occurs, the second time period during and after the anomaly occurs), as well as the corresponding personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics of each time period. This time period division clearly illustrates the manifestations of abnormal events at different stages, facilitating analysis of their development process. The three types of characteristics, personnel, environment, and equipment, reveal the inherent causes of construction anomalies from different dimensions, providing key data support for the construction of a construction anomaly hazard model. This model can learn the characteristic patterns of various abnormal events, laying the foundation for subsequent accurate hazard identification.

[0032] On this basis, a pre-set model is trained using extracted human behavior, environmental parameters, and equipment operation characteristics to develop a model capable of identifying construction anomalies and hidden dangers. Because the input features encompass multiple factors contributing to abnormal events, the model can fully learn the correlations between different feature combinations and hidden dangers. Through continuous parameter optimization through extensive data training, the model ultimately achieves high recognition accuracy and generalization capabilities, enabling reliable identification of potential hazards in practical applications and ensuring construction safety.

[0033] In real-time application, real-time information on personnel behavior, equipment operation, and environmental parameters is first processed with reference to historical features. After extracting real-time features, they are matched and compared with historical features to generate construction precursor data. This process filters and analyzes real-time information based on patterns in historical data, extracting key information related to hidden dangers. This makes the data input into the model more targeted, effectively improving recognition efficiency and accuracy, and facilitating the timely detection of potential anomalies.

[0034] Inputting construction precursor data into the trained model yields hazard identification results. Because the precursor data contains key construction features, and the model understands the correlation between features and hazards, it can quickly determine if anomalies exist and output results. This provides clear direction for subsequent hazard management and helps prevent accidents by taking timely measures.

[0035] If the identified hidden dangers are abnormal, the system will first determine the location of the abnormal area and then perform a hidden danger weight analysis on that area to determine the hidden danger coefficient. Accurate regional positioning provides accurate location information for hidden danger treatment; the weight analysis comprehensively considers the impact of factors such as personnel, environment, and equipment in the area on the hidden dangers, allowing the hidden danger coefficient to objectively reflect the severity of the regional hidden dangers, providing a scientific basis for subsequent level determination, and facilitating more accurate risk assessment and targeted treatment.

[0036] Subsequently, a hazard anomaly level is determined by combining the hazard coefficient, the construction anomaly data from the identification results, and the corresponding causes. This level integrates the regional risk level, the specific manifestations of the hazards, and the causes, providing a clear standard for handling decisions, improving the efficiency and effectiveness of hazard handling and reducing construction risks.

[0037] When the level of hidden danger anomalies reaches a preset standard, the system generates a hidden danger anomaly warning based on the construction anomaly data and causes. This warning mechanism, based on level determination, is triggered only when the hidden danger reaches a certain level of severity. The warning information includes specific anomaly data and causes, making it more targeted and practical, prompting relevant personnel to pay attention to and address hidden dangers, preventing them from escalating.

[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. It should also be noted that the term "and / or" appearing in the present application indicates that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " appearing in the present application, unless otherwise specified, generally indicates that the objects associated with each other are in an "or" relationship.

[0039] One embodiment of the present application provides a method for automatically identifying construction safety hazards based on deep learning, which is executed by an electronic device, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services; the terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited to this. The terminal device and the server can be directly or indirectly connected through wired or wireless communication. This embodiment of the application does not limit this. Figure 1 As shown, the method includes steps S10 to S17: Step S10: Obtain personnel behavior information, equipment operation information, and environmental parameter information.

[0040] The equipment operation information includes the operation information of each equipment itself and the interactive operation information of related equipment. The environmental parameter information is the environmental information of the area where the equipment is located.

[0041] For the purposes of this application, personnel behavior information refers to a collection of data related to personnel activities. This refers to information such as personnel's actions, operating habits, and movement trajectories within the construction area, captured through various sensors and monitoring devices. For example, in a construction workshop, cameras installed near equipment can record data such as the operator's operating process, operating frequency, and movement routes within the workshop. This information constitutes personnel behavior information. Equipment operation information refers to data reflecting the equipment's operating status and operational status. This information includes each device's own operational information and interactive operation information for related devices. The operational information for each device represents the various parameters and status of the device during independent operation, such as its startup time, operating duration, workload, and energy consumption. The interactive operation information for related devices represents the coordination between related devices during operation within a production process or system, such as the flow rate and speed of raw materials delivered from one device to another, as well as the sequence of operations and signal interaction between the two devices. Environmental parameter information represents data on the environmental conditions within the area where the device is located. It refers to the information obtained through various environmental monitoring devices such as temperature sensors, humidity sensors, light sensors, and air quality sensors, such as the temperature, humidity, light intensity, and air quality (such as dust concentration and harmful gas concentration) of the equipment's environment.

[0042] In the embodiments of the present application, to acquire human behavior information, multiple high-definition cameras are first installed in the human activity area to ensure coverage of all areas where people are active. Image recognition technology is then used to analyze the video images captured by the cameras to identify information such as human behavior, movement, and location. The recognition results are then stored in a database for subsequent query and analysis. To acquire device operation information, a data acquisition module is first installed on each device to collect the device's own operating parameters, such as operating time and workload. For related devices, a communication network is then established between the devices, using a specific communication protocol (such as Modbus or Profinet) to enable data exchange between the devices and acquire interactive operation information. The collected device operation information is then transmitted to a data processing center via wired or wireless means for storage and processing. To acquire environmental parameter information, appropriate environmental monitoring devices, such as temperature sensors and humidity sensors, are selected based on the environmental characteristics of the area where the devices are located. These sensors are then installed in appropriate locations. The sampling frequency and data transmission method of the monitoring devices are then configured to ensure real-time and accurate acquisition of environmental parameter information. The data collected by the monitoring devices is then transmitted to the data processing center for data cleaning, analysis, and storage.

[0043] Step S11. Collect historical construction abnormality information and the construction abnormality cause corresponding to each construction abnormality event in the historical construction abnormality information, and perform feature extraction on the historical construction abnormality information to obtain time period features and personnel behavior features, environmental parameter features, and equipment operation features corresponding to the time period features.

[0044] The time period characteristics include a first time period before each abnormal construction event occurs, a time period during the occurrence, and a second time period after the occurrence.

[0045] For the embodiments of the present application, historical construction anomaly information refers to a data set formed by situations that occurred in past construction projects that were inconsistent with normal construction processes, standards or expectations. It refers to a detailed record of various abnormal conditions in the past construction process. Abnormal conditions include delayed construction progress, substandard construction quality, safety accidents, etc. Construction abnormal events refer to specific events that deviate from the normal construction state during the construction process. They are used to indicate unexpected situations caused by various factors during the construction process. These situations will have an adverse impact on the smooth progress, quality, safety, etc. of the construction. Construction abnormality causes refer to various factors that trigger the occurrence of construction abnormal events. It is used to indicate the root cause of abnormal conditions in construction. The cause may be human factors, such as construction personnel's operational errors, improper management personnel's instructions, or environmental factors, such as bad weather, changes in geological conditions, or equipment factors, such as equipment failure, aging, etc. The time period feature is used to represent the characteristics of construction abnormal events at different time stages. It includes the first time period before each construction abnormal event occurs, the time period during the occurrence, and the second time period after the occurrence. The first time period before an abnormal event occurs can help analyze potential influencing factors before the event occurs; the time period during the event reflects the real-time situation at the time of the abnormal event; and the second time period after the event helps assess the impact of the abnormal event on subsequent construction and the parameters after normal construction. Personnel behavior characteristics represent the behavioral characteristics of construction personnel during a specific time period. They are information reflecting personnel behavior characteristics extracted by analyzing data on their operating actions, work attitudes, and collaboration during the construction process. Environmental parameter characteristics represent the characteristics of relevant parameters of the construction environment during a specific time period. They are information reflecting changes in environmental conditions extracted by monitoring parameters such as temperature, humidity, wind speed, light intensity, and air quality. For example, if the ambient temperature suddenly rises during an abnormal construction event, the trend and magnitude of this temperature change are environmental parameter characteristics. Equipment operation characteristics represent the characteristics of the operating status of construction equipment during a specific time period. They are information reflecting the equipment's operating status extracted by analyzing data such as equipment operating parameters (such as speed, power, load, etc.), operating time, and fault frequency.

[0046] The method for collecting specific historical construction abnormality information and the construction abnormality causes corresponding to each construction abnormality event in the historical construction abnormality information is the same as the method for obtaining personnel behavior information, equipment operation information and environmental parameter information in step S10. The difference is that according to the records of the construction abnormality events that have occurred and the time period, the two types of data information are bound with the personnel behavior information, equipment operation information and environmental parameter information to obtain the construction abnormality information and the construction abnormality causes.

[0047] Step S12: training a preset construction abnormality hidden danger model based on personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics to obtain a construction abnormality hidden danger model.

[0048] Specifically, a first behavioral distinguishing feature, a first environmental parameter feature difference, and a first equipment operation feature difference are determined based on the personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics corresponding to the second time period and the personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics corresponding to the first time period. A second behavioral distinguishing feature, a second environmental parameter feature difference, and a second equipment operation feature difference are determined based on the personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics corresponding to the second time period and the personnel behavior characteristics, environmental parameter characteristics, and equipment operation characteristics corresponding to the time period during the occurrence process. The first behavioral distinguishing feature, the first environmental parameter feature difference, and the first equipment operation feature difference are sorted for construction anomaly trends to obtain precursor dynamic data corresponding to each construction anomaly event. The second behavioral distinguishing feature, the second environmental parameter feature difference, and the second equipment operation feature difference are sorted for construction anomalies to obtain construction anomaly data corresponding to each construction anomaly event. The precursor dynamic data, construction anomaly data, and the cause of the construction anomaly are input into a preset construction anomaly hidden danger model according to time nodes for training to obtain a construction anomaly hidden danger model.

[0049] Specifically, the first behavioral distinguishing feature represents the difference in human behavior between the second time period and the first time period. This feature is extracted by comparing human behavior data before and after the abnormal event, reflecting behavioral changes. The first environmental parameter characteristic difference represents the difference in environmental parameters between the second time period and the first time period. This feature is calculated by calculating the difference between environmental parameters (such as temperature and humidity) between the two time periods, reflecting environmental changes. For example, if the ambient temperature drops by 2 degrees Celsius after the abnormal event compared to before the event, this difference is the first environmental parameter characteristic difference. The first equipment operation characteristic difference represents the difference in equipment operation between the second time period and the first time period. This feature is extracted by comparing equipment operation data (such as operating efficiency and fault frequency) between the two time periods. The second behavioral distinguishing feature represents the difference in human behavior between the second time period and the duration of the abnormal event. This feature is extracted by comparing human behavior data after and during the abnormal event. The second environmental parameter characteristic difference represents the difference in environmental parameters between the second time period and the duration of the abnormal event. This feature is calculated by calculating the difference between environmental parameters between the two time periods, reflecting environmental changes. The second equipment operation characteristic difference represents the difference in equipment operation characteristics between the second time period and the time period during which the event occurred. This information is extracted by comparing equipment operation data from the two time periods. Precursor dynamic data refers to information that precedes an abnormal event by analyzing the characteristic differences between the first and second time periods. It indicates trends in human behavior, environmental parameters, and equipment operation before a construction abnormality occurs, indicating an impending abnormality. For example, if equipment efficiency gradually decreases one week before a failure, this downward trend is considered precursor dynamic data. Construction abnormality data refers to information related to the abnormal event, obtained by analyzing the characteristic differences between the time period during which the event occurred and the second time period. It indicates the specific manifestations of the construction abnormality and the recovery after the event. The pre-configured construction abnormality hazard model is a pre-built deep learning model framework for identifying construction abnormality hazards. Based on professional knowledge and experience in the construction field, it is a preliminary model structure that receives precursor dynamic data, construction abnormality data, and the causes of construction abnormalities, and uses algorithms and rules to identify potential hazards.

[0050] In an embodiment of the present application, data analysis tools (such as Python's Pandas library) are used to align and preprocess the time period feature data for each construction anomaly event to ensure accurate correspondence between the data's time nodes. A feature difference calculation script is then compiled to calculate the feature differences between the second time period and the first time period, and between the second time period and the time period during the occurrence process, respectively. This yields the first and second behavioral distinguishing features, the environmental parameter feature differences, and the equipment operation feature differences. Statistical analysis methods (such as regression analysis and trend analysis) are then used to organize the feature difference data, extracting precursor dynamic data and construction anomaly data. This organized data and the causes of the construction anomaly are then input into a pre-set machine learning model (such as a decision tree model). The model parameters are then adjusted through training to produce a construction anomaly hazard model.

[0051] Step S13: Processing the personnel behavior information, equipment operation information and environmental parameter information according to the personnel behavior characteristics, environmental parameter characteristics and equipment operation characteristics to obtain construction precursor data.

[0052] Specifically, feature extraction is performed on personnel behavior information, equipment operation information, and environmental parameter information to obtain real-time behavior features, real-time operation features, and real-time parameter features. Feature matching is performed on the real-time parameter features and real-time operation features with the environmental parameter features and equipment operation features during the time period of the occurrence process to determine whether there is an operation feature match and / or parameter feature match. If not, feature matching is performed on the real-time behavior features, real-time operation features, and real-time parameter features with the personnel behavior features, environmental parameter features, and equipment operation features during the second time period after the occurrence of the time period to obtain comparison behavior features, comparison parameter features, and comparison operation features. Feature comparison processing is performed on the real-time behavior features, real-time operation features, and real-time parameter features based on the comparison behavior features, comparison parameter features, and comparison operation features to obtain construction precursor data.

[0053] Specifically, behavioral feature differentiation analysis is performed on the compared behavior features and the real-time behavior features to obtain real-time behavioral differentiation features. Real-time parameter features are then differentiated and compared with the compared parameter features to obtain real-time environmental parameter feature differences. Real-time operation features are then differentiated and compared with the compared operation features to obtain real-time operation parameter feature differences. Trend analysis is performed on the real-time behavioral differentiation features, the real-time environmental parameter feature differences, and the real-time operation parameter feature differences to obtain construction precursor data.

[0054] Step S14: Input the construction precursor data into the construction abnormality hidden danger model for identification to obtain the hidden danger identification result.

[0055] Specifically, the output of the construction anomaly hazard model, after processing and analyzing the input construction precursor data, is determined based on the hazard identification results. This result clearly indicates whether a hazard exists in the construction scenario corresponding to the input data, as well as the specific circumstances of the hazard, such as its type (equipment failure, human error, environmental safety risk, etc.), its location, expected timeframe for occurrence, and potential hazards. For example, a hazard identification result might indicate, "In the operating area of ​​tower crane No. 3, there is a potential for equipment brake system failure, which is expected to occur within the next 24 hours."

[0056] Step S15: Determine whether there is at least one hidden danger anomaly in the hidden danger identification result. If so, determine the regional location where the hidden danger anomaly exists, and perform hidden danger weight analysis on the regional location to obtain the hidden danger coefficient corresponding to the regional location.

[0057] Specifically, an image of the construction area is obtained, and a three-dimensional construction model of the construction area is constructed based on the image of the construction area. Based on the three-dimensional construction model, concentrated hidden danger areas that meet preset conditions and dispersed hidden danger areas that do not meet preset conditions are determined. The preset conditions are that a specific number of people are present and adjacent equipment is within a specific distance. The concentrated hidden danger areas and dispersed hidden danger areas are respectively used as hidden danger area points, and the hidden danger area points are connected according to the time node sequence corresponding to the abnormal construction events to obtain a hidden danger trend curve. The hidden danger trend curve is subjected to regular extension analysis to obtain a predicted trend curve of the probability of hidden danger anomalies occurring in the future period. The future regional points corresponding to the predicted abnormal trend curve are determined, and the hidden danger coefficients corresponding to different regional locations in the construction area are determined based on the concentration and dispersion characteristics of the future regional points and the hidden danger area points.

[0058] In the embodiments of this application, a construction area image refers to image data reflecting the actual scene of a construction area, captured by various image acquisition devices (such as cameras and drone-mounted cameras). These images can contain information such as the construction site layout, building structure, equipment placement, and personnel activities, and serve as the fundamental data source for constructing a 3D construction model. For example, panoramic images captured by drones during aerial photography of a large construction site constitute a construction area image. A 3D construction model is a virtual 3D spatial model constructed based on the construction area image using 3D modeling techniques (such as computer vision and 3D reconstruction algorithms). It accurately depicts the three-dimensional structure, spatial relationships, and object morphology of the construction area, providing intuitive visualization support for subsequent hazard analysis. For example, a 3D construction model clearly shows the layout of each floor within a building, the location of equipment, and the movement paths of personnel. Within a 3D construction model, areas that meet specific conditions (a certain number of personnel and a certain distance between adjacent equipment) are defined as concentrated hazard areas. These areas, due to the dense concentration of personnel and equipment, present high safety risks, such as collisions and chain reactions caused by equipment failures. Dispersed hazard areas, as opposed to concentrated hazard areas, are defined as areas that do not meet the aforementioned specific conditions. These areas have relatively dispersed personnel and equipment distribution, resulting in relatively low safety hazards, but may also present isolated safety issues, such as individual equipment failures or personnel misconduct. For example, the periphery of a construction site, where personnel and equipment are sparse but hazards such as improper material stacking exist, is considered a dispersed hazard area. Hazard area points mark concentrated and dispersed hazard areas in the 3D construction model. Each marked point represents a hazard area point, which contains information such as the location and type of hazard area (concentrated or dispersed), forming the basis for subsequent hazard analysis and prediction. For example, in the 3D construction model, different colored markers represent concentrated and dispersed hazard areas, respectively. A hazard trend curve is formed by connecting hazard area points according to the time sequence of corresponding construction abnormal events. This curve reflects the changes in hazard areas over time, including changes in location and number, and helps analyze hazard trends. For example, a hazard trend curve can be used to observe the gradual expansion or shift of a concentrated hazard area over time. The predicted trend curve is an extended analysis of the hidden danger trend curve. Based on historical data and trend patterns, it predicts the changing probability of hidden danger anomalies in future cycles. The resulting curve is called the predicted trend curve. This curve provides forward-looking guidance for construction safety management, helping to take preventive measures. Future regional points are determined based on the predicted trend curve to identify regional points with hidden dangers in the future cycle.The hidden danger coefficient is determined for different locations within the construction area based on the future location of the area and the concentration and dispersion of the hidden danger points. The hidden danger coefficient is a quantitative indicator used to measure the likelihood of hidden dangers in different areas. A higher coefficient indicates a greater hidden danger risk. For example, the hidden danger coefficient is higher in areas with concentrated hidden dangers, while it is relatively lower in areas with dispersed hidden dangers.

[0059] For the embodiment of the present application, the specific calculation method of the hidden danger coefficient includes: (1) Determine the quantitative indicators of the degree of centralization and decentralization: Concentration Index (C): For each potential hazard area, count the number of personnel and equipment within a certain radius (e.g., within a 50-meter radius). The greater the number of personnel, the greater the number of equipment, and the closer the distance between them, the higher the concentration. For example, set the weight of personnel to 0.6 and the weight of equipment to 0.4, and use linear weighting to calculate the concentration index. If an area has 20 personnel and 10 pieces of equipment, with the equipment distances closely spaced, the personnel score is (20 / maximum capacity of the area) × 0.6 + the equipment score is (10 / maximum capacity of the area) × 0.4 = the concentration index. (Assuming the maximum capacity is 50 personnel and the maximum capacity is 20 equipment, the personnel score is 0.4, the equipment score is 0.5, and the concentration index is 0.4 × 0.6 + 0.5 × 0.4 = 0.44.)

[0060] Decentralization (D): In contrast to centralization, a high degree of decentralization indicates that personnel and equipment are more sparsely distributed. The decentralization index can be calculated as 1 minus the centralization index: D = 1 - C.

[0061] (2) Setting the basic hidden danger coefficient: The basic hidden danger coefficient for concentrated hidden danger areas is set to 1.5, and the basic hidden danger coefficient for dispersed hidden danger areas is set to 0.8.

[0062] (3) Calculate the final hidden danger coefficient: For each region, the basic hidden danger coefficient is adjusted based on its concentration and dispersion index. For example, using linear interpolation, the final hidden danger coefficient (H) = basic hidden danger coefficient × (1 + adjustment coefficient × (concentration index - baseline value)). The baseline value can be set based on actual conditions, such as 0.5. The adjustment coefficient can be set based on sensitivity to concentration and dispersion, such as 0.3. If the concentration index of a concentrated hidden danger area is 0.7, the basic hidden danger coefficient is 1.5, the baseline value is 0.5, and the adjustment coefficient is 0.3, then the final hidden danger coefficient H = 1.5 × (1 + 0.3 × (0.7 - 0.5)) = 1.5 × (1 + 0.06) = 1.59.

[0063] Specifically, the hazard development vector extending from different hazard area points to the next hazard area point and the abnormal feature set corresponding to each hazard area point are determined based on the hazard trend curve. The hazard vector features are determined based on the hazard development vectors, and the hazard vector features are added to the abnormal feature set to obtain a hazard feature set. Each hazard feature set is arranged in a matrix according to time sequence to obtain a hazard feature matrix corresponding to each hazard feature set. The hazard feature matrix is ​​deduced from the hazard feature set according to time periods to obtain multiple hazard point matrices in the future period. Based on the multiple hazard point matrices, the future hazard feature set is determined, and the future hazard feature set is imported into the three-dimensional construction model to obtain a predicted trend curve for the probability of hazard anomalies occurring in the future period.

[0064] Step S16: Determine the hidden danger level based on the hidden danger coefficient corresponding to the regional location and the construction abnormality data and the cause of the construction abnormality in the hidden danger identification result to obtain the hidden danger abnormality level.

[0065] In the embodiment of the present application, the hidden danger coefficient is divided into different intervals, corresponding to different basic hidden danger level tendencies.

[0066] For example: hidden danger coefficient H∈[0,0.3): low hidden danger tendency, corresponding to the basic hidden danger level of level one (minor hidden danger); hidden danger coefficient H∈[0.3,0.7): medium hidden danger tendency, corresponding to the basic hidden danger level of level two (general hidden danger); hidden danger coefficient H∈[0.7,1): high hidden danger tendency, corresponding to the basic hidden danger level of level three (serious hidden danger); then match the hidden danger coefficients obtained in step S15 with the corresponding interval coefficients respectively to obtain the basic hidden danger level.

[0067] The construction anomaly data and the cause of the construction anomaly are then input into the preset construction anomaly level determination criteria for comparison, resulting in the corresponding construction hazard level. The preset construction anomaly level determination criteria is a pre-established system of rules for classifying construction anomalies and determining hazard levels. It clarifies the hazard levels corresponding to different combinations of construction anomaly data and causes, and serves as the basis for grading construction anomalies. The construction hazard level is determined based on the construction anomaly data and causes, according to preset standards, to indicate the severity of the construction hazard. It is typically divided into Level 1 (minor hazard), Level 2 (general hazard), Level 3 (serious hazard), and Level 4 (particularly serious hazard), and is used to indicate the impact of the construction hazard on construction safety, progress, and quality.

[0068] The foundation hidden danger level and the construction hidden danger level are cumulatively calculated to obtain the hidden danger abnormality level.

[0069] Step S17: Determine whether the hidden danger abnormality level meets the preset abnormality level. If so, generate a hidden danger abnormality warning based on the construction abnormality data and the cause of the construction abnormality.

[0070] Specifically, the preset anomaly level is a pre-set reference level used to determine whether a potential hazard anomaly level warrants a warning. This level is determined based on factors such as the project's characteristics, safety requirements, and historical experience, and is used to clarify the severity of the potential hazard that warrants a warning. In this embodiment, the preset anomaly level is 4 or greater.
