[0020] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0022] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0023] Embodiment 1, referring to Figure 1 and Figure 2 , is the first embodiment of the present invention. This embodiment provides a safety construction management method for building engineering, including the following steps: S1. Based on the building design drawings and project plans, construct a 3D BIM model.

[0024] S1.1. The 3D BIM model includes building structure information, equipment and facility information, construction sequence information, and annotation information of key safety monitoring points.

[0025] Specifically, the building structure information includes all building components, such as the geometric shapes, material properties, and positional relationships of beams, columns, floors, walls, etc. The material properties of each component, such as compressive strength, elastic modulus, and durability, must be input through predefined parameters; the equipment and facility information includes the locations and operating parameters of elevators, pipelines, and water and power supply systems; the construction sequence information is not only static building information but also should integrate the construction process. By decomposing the construction tasks into discrete construction stages and combining with a time schedule, a 4D BIM model (space + time) is generated for subsequent construction progress management; the annotation of key safety monitoring points refers to marking areas prone to safety accidents in the 3D BIM model, such as high-altitude operation areas, deep foundation pits, heavy machinery operation areas, etc. These monitoring points will be combined with subsequent sensor data to be used for real-time monitoring of the status of dangerous areas, and through the scene simulation function of BIM software, the visualization display of potential dangerous areas during the construction process is carried out.

[0026] S2. Real-time collect the status data of the construction site and transmit it to the 3D BIM model for dynamic update.

[0027] S2.1. The status data of the construction site includes environmental data, building structure data, equipment status data, and personnel behavior data.

[0028] Specifically, environmental data refers to the real-time collection of temperature, humidity, noise, vibration, etc. using environmental sensors deployed at the construction site; building structure data refers to the monitoring of stress and displacement at key parts of the building using stress sensors; equipment status data refers to the collection of information such as temperature, vibration, and load of the equipment using status monitoring sensors on the equipment; personnel behavior data refers to the use of RFID tags or positioning devices to track the location and safety operation of workers, and detect whether the behavior of workers complies with safety regulations (such as whether they wear safety helmets and whether they are active in dangerous areas).

[0029] S2.2. Transmit the collected data to the 3D BIM model through the Internet of Things gateway using the MQTT protocol for preliminary processing; the preliminary processing includes data cleaning, data interpolation, and data standardization.

[0030] Specifically, data cleaning refers to using statistical methods (such as the 3σ rule) to identify and eliminate abnormal data outside the normal range; data interpolation refers to using the linear interpolation method to fill in part of the missing data; data standardization refers to standardizing the data from different sensors for subsequent unified processing.

[0031] S2.3. Dynamically update the status data of the construction site after preliminary processing transmitted to the 3D BIM model.

[0032] S2.3.1. Define the attributes of each area and structure in the 3D BIM model, including environmental conditions, structural stress, equipment status, and personnel activity range; preliminarily match the status data of the construction site after preliminary processing with the corresponding areas and structures in the 3D BIM model.

[0033] Specifically, environmental sensors (such as temperature, humidity, noise, vibration sensors) will be assigned to the corresponding building areas (such as floors, rooms, exterior walls, etc.) in the 3D BIM model; building structure sensors (such as stress or displacement sensors) will be assigned to specific building components (such as beams, columns, walls); equipment monitoring sensors (such as temperature, vibration, load sensors) will be matched with the equipment (such as cranes, electromechanical equipment) in the 3D BIM model; personnel behavior data (such as RFID tags, camera monitoring) will be matched with the building areas and personnel locations in the 3D BIM model.

[0034] S2.3.2. Set the environmental threshold according to the preliminary matching results, and dynamically associate the real-time collected environmental data with the building areas and working conditions in the 3D BIM model. After the dynamic association of the environmental data is completed, input the stress and displacement data of the building structure into the 3D BIM model to complete the dynamic association between the building structure data and the structural components in the 3D BIM model. After the dynamic association of the building structure is completed, input the equipment status data into the 3D BIM model to dynamically associate with the construction equipment. After the dynamic association of the equipment data is completed, input the personnel behavior data into the 3D BIM model and dynamically associate with the worker positions and behaviors in the model. Integrate the status data after the dynamic associations into a unified 3D BIM model.

[0035] Specifically, based on the preliminary matching of the sensor data with the 3D BIM model, the real-time collected environmental data (such as temperature, humidity, noise, vibration) will be input into the 3D BIM model, set the environmental threshold, and compare the environmental threshold (such as the temperature upper limit of 35°C, the noise upper limit of 85 dB, etc.) with the real-time environmental data. If the environmental data in a certain area exceeds the environmental threshold, the 3D BIM model will automatically mark this area as an environmental non-compliance area. For example, if the noise sensor at a certain site detects a decibel value exceeding 85 dB, this area will be marked as a red warning area. At the same time, an environmental warning prompt will be generated to remind the management personnel to pay attention to the environmental anomaly in this area.

[0036] Comprehensively set the safety threshold based on the historical engineering safety data and the safety factor under the actual working conditions. If the stress or displacement of a certain building component exceeds the safety threshold, mark this component as a high-risk component. For example, when the stress value of a certain beam exceeds its safety threshold, the 3D BIM model will automatically mark this beam as red and generate a structural safety warning. At the same time, it will recommend taking corresponding safety measures, such as suspending construction or strengthening this component.

[0037] The equipment sensors (such as temperature sensors, vibration sensors, load sensors) monitor the operating status of the equipment in real time and compare the operating status of the equipment with the historical operating parameters of the equipment. Once the operating status of the equipment (such as temperature, vibration or load) exceeds the safe range of the operating status, the equipment will be automatically marked as equipment anomaly. For example, if the load of a certain crane exceeds its rated value, the 3D BIM model will mark this crane as red and issue a load overrun warning, and will recommend equipment maintenance or stop operation until the equipment status returns to normal.

[0038] The location information monitored by RFID tags or cameras will be matched with the building areas in the 3D BIM model to update the workers' locations in real time. For example, it can detect whether a worker has entered a high-risk area (such as the elevated work area, foundation pit, near dangerous machinery, etc.); it can judge whether the workers' behaviors comply with safety regulations through computer vision or sensor data. For example, the camera can detect whether a worker is wearing a safety helmet through computer vision algorithms; if a certain worker enters a high-risk area and is not wearing a safety helmet, the 3D BIM model will mark this area as an area of unsafe operation by personnel and generate a personnel safety warning. The warning information will be fed back to the on-site management personnel in real time and it is recommended to take immediate measures, such as reminding the worker to wear safety equipment or temporarily evacuating the dangerous area.

[0039] S3. Conduct comprehensive safety data analysis based on the dynamically updated 3D BIM model to identify potential safety hazards.

[0040] S3.1. Extract the real-time status data of the construction site from the dynamically associated 3D BIM model to construct a multi-dimensional data collection pool; based on the multi-dimensional data collection pool, use data fusion algorithms to cross-analyze different types of data to obtain preliminary analysis results of various potential risks.

[0041] Specifically, through data fusion algorithms, obtain preliminary analysis results of various potential risks, such as: Equipment risk: After synthesizing the vibration, temperature, and load data of the equipment, judge whether there is a risk of overload, wear, or impending failure of the equipment. Environmental risk: Combine environmental data and worker distribution data to judge whether there are workers in areas with excessive harmful gases or inappropriate temperature and humidity. Structural risk: Fuse the stress, deformation, and displacement data of building components to judge whether certain components are on the verge of overloading or impending structural damage.

[0042] S3.2. Extract historical data related to the real-time status data of the current construction site from historical data and conduct further trend analysis for the preliminary analysis results to predict future risks. The expression is: ; where, represents the risk at time , represents the total number of data categories, represents the data category index, represents the total length of the acquisition time, represents the th risk weight of the data category, represents the environmental data at time , represents the building structure data at time ; Personnel behavior data indicating time and a time decay coefficient related to the risk of the nth type of data, where the time decay coefficient is related to the risk of the nth type of data, and represents the time difference between the current data and the historical data, and the standard deviation of the nth type of data, and a correction factor for the historical data related to the risk of the nth type of data; Trend analysis: Equipment trend analysis: By comparing the vibration, temperature, load, etc. data of the current equipment with the historical data, it is determined whether the equipment is approaching the critical state before failure. For example, if the vibration trend of a certain equipment is similar to the trend before the equipment failed historically, it is predicted that the equipment may fail in a period of time in the future.

[0043] Environmental trend analysis: Based on the historical environmental data and the current conditions, the change trend of environmental parameters is analyzed. For example, if the weather forecast shows that the temperature will rise significantly in the next few days, and the historical data indicates that the strength of some construction materials will decrease in a high-temperature environment, it is predicted that there may be potential structural safety hazards in this area.

[0044] Structural trend analysis: By comparing the stress, displacement, etc. data of the current building components with the historical records, it is predicted whether some components are gradually approaching the design limit. For example, the displacement trend of a certain support structure indicates that its stability is gradually decreasing, and there may be a risk of collapse in the future.

[0045] Based on the trend analysis, the possible risks in the future are predicted, specifically including: Equipment failure prediction: Predict that some equipment may be damaged in the next few hours or days. Environmental deterioration prediction: Predict that the environmental conditions in some areas in the future may become unsuitable for construction or may pose a threat to the health of workers. Structural damage prediction: Predict that some building components may have structural problems or damage during future construction.

[0046] S3.3. Generate corresponding early warnings according to the analysis results, and classify the early warnings according to the risk levels according to the severity of different potential hazards.

[0047] Specifically, the early warning includes the threshold judgment criteria for various safety hazards. In this embodiment, the early warning includes equipment failure early warning and structural safety early warning.

[0048] Equipment failure warning means that when the vibration value of the equipment exceeds the safety threshold and the historical trend indicates that the vibration continues to rise, an equipment failure warning will be issued. Structural safety warning means that when the stress of a building component exceeds the corresponding safety value and the displacement data shows an abnormal deformation trend, a structural safety warning will be issued.

[0049] The warning levels are generally divided into: Low risk (green warning): The warning indicates that the potential risk is relatively low and will not cause serious impact on the construction site in the short term. For example, the vibration of a certain equipment is slightly higher than the normal value but still within the controllable range. It is recommended to monitor the equipment status regularly. Medium risk (yellow warning): The warning indicates that the potential risk is relatively large and may affect the construction progress and personnel safety. For example, the temperature in a certain area is gradually rising, which may affect the health of workers. It is recommended that the management take preventive measures and closely monitor the environmental changes. High risk (red warning): The warning indicates that the risk is very serious and may lead to equipment failure, structural damage or casualties. It is recommended to take emergency measures immediately, such as suspending construction, evacuating workers or performing equipment maintenance.

[0050] It should be noted that the warning classification method can also be determined according to experience and is not restricted in this embodiment.

[0051] S4. Generate an automated safety decision-making plan according to the recognition result.

[0052] S4.1. According to different construction scenarios and potential safety hazards, identify the warning types that may be triggered; for different warning types, establish a decision rule library containing various treatment plans.

[0053] Specifically, the main content of the decision rule library: Equipment failure rules: For warnings of abnormal equipment status, generate corresponding decisions according to the equipment health status. For example, if the equipment vibration is abnormal, it is recommended to suspend the use of the equipment and generate a maintenance plan. Building structure rules: For the stress or displacement exceeding the standard of building components, generate corresponding decisions according to the structural risk, such as reinforcement suggestions, construction suspension, etc. Environmental factor rules: For abnormal environmental data (such as temperature, humidity, noise exceeding the standard), automatically suggest adjusting the construction plan to avoid construction under adverse environments. Personnel safety rules: For the situation where workers do not operate according to safety regulations, generate safety training suggestions and suspend unsafe operations.

[0054] S4.2. Based on the real-time status data of the equipment, judge whether the current operating status of the equipment is normal.

[0055] Specifically, judge whether the current operating status of the equipment is normal: Vibration data comparison: Compare the real-time vibration value with the normal vibration range of the equipment. If the vibration value is within the normal range, the equipment status is evaluated as "normal"; if the vibration value exceeds the normal vibration range, the equipment status is evaluated as "abnormal". Temperature data comparison: Compare the real-time temperature data with the safe temperature range of the equipment. If the temperature exceeds the upper limit, it is evaluated that the equipment has an overheating risk. Load data comparison: Evaluate the load status of the equipment to determine whether the equipment is operating overloaded.

[0056] If all parameters of the equipment are within the safe range, it is evaluated that the equipment is in normal operation and no further action is required. If any parameter exceeds the safe range, the equipment is judged to be in an abnormal state and enters the next step of abnormal type analysis.

[0057] S4.3. When a certain parameter of the equipment is detected to exceed the safe range, further analyze the type and severity of the abnormality.

[0058] Abnormal type classification: Vibration abnormality: Analyze the vibration frequency and amplitude to determine whether it is caused by loose or worn internal components of the equipment or external impacts. Temperature abnormality: If the temperature is too high, analyze whether it is caused by ambient temperature, excessive equipment load, or failure of the equipment cooling system. Load abnormality: If the load exceeds the standard, analyze whether it is due to unreasonable equipment task allocation, overweight materials, or aging of the equipment structure.

[0059] Severity assessment: Low severity: The parameter slightly exceeds the safe range, and the equipment can still continue to run for a short time, but needs to be closely monitored. Medium severity: The equipment must be suspended to prevent further damage, and maintenance needs to be arranged as soon as possible. High severity: The equipment has a major abnormality and there is a risk of immediate damage, and it is necessary to stop the machine urgently and start a comprehensive overhaul.

[0060] S4.4. Automatically generate detailed maintenance suggestions according to the type and severity of the abnormality.

[0061] Content of maintenance suggestions: Maintenance time suggestion: According to the severity level of the equipment, suggest the urgency of maintenance. For example, "high severity" suggests immediate emergency maintenance, and "low severity" suggests handling during the next regular maintenance.

[0062] S4.5. The decision rule library automatically generates a corresponding equipment maintenance plan according to the detailed maintenance suggestions.

[0063] Details of the maintenance plan: Vibration anomaly: It is recommended to check and replace the vulnerable parts of the equipment (such as bearings, gears, etc.), and recalibrate the equipment. Temperature anomaly: It is recommended to check the cooling system, clean the cooling holes, or replace the coolant. Load anomaly: It is recommended to reallocate the equipment tasks to reduce its load, or check whether there is damage to the equipment structure. Maintenance personnel allocation: Automatically allocate the most suitable technicians for maintenance according to the complexity of the maintenance tasks and the worker skill database.

[0064] S5. Automatically generate a construction adjustment plan based on the safety decision-making plan.

[0065] S5.1. According to the building structure data in the 3D BIM model, analyze the stress, displacement, construction equipment status, and personnel behavior data of the current building structure in real time, and calibrate the high-risk areas at the current construction site.

[0066] Specifically, the basis for identifying high-risk areas: Structural stress data: If the stress of a certain component exceeds the design safety range, mark this area as a high-risk area. For example, if the stress value of a certain beam or column exceeds the ultimate strength of the material, it may break or collapse. Displacement or deformation data: If there is excessive displacement or deformation in the structure of a certain area, mark this area as high-risk. For example, if a certain wall or support structure tilts beyond the safety threshold, it may collapse. Environmental impact data: External environments such as strong winds, heavy rains, and extreme temperatures may affect the stability of certain areas. Based on the analysis of environmental data, mark the affected high-risk areas.

[0067] The calibration process of high-risk areas: Area division: Divide the project into multiple construction areas through the building component data of the 3D BIM model. The safety status of each area is jointly determined by its structural stress, displacement, and other data.

[0068] Color identification: The marked high-risk areas will be identified in the 3D BIM model with a prominent color (such as red), and the low-risk areas will be identified with green or yellow. Managers and workers can intuitively view the distribution of high-risk areas through the 3D BIM model.

[0069] S5.2. According to the current construction progress, worker distribution, and the latest status of high-risk areas, predict the time changes of each process; based on the prediction results, automatically adjust the construction sequence; according to the adjusted construction sequence and the latest status of high-risk areas, automatically allocate workers to safe areas, and dynamically match tasks suitable for workers based on the personal status of workers; update the adjusted construction sequence and worker allocation results to the construction schedule in the 3D BIM model in real time to generate a construction adjustment plan.

[0070] Specifically, the rules for adjusting the construction sequence: Construction suspension in high-risk areas: First, all construction tasks in high-risk areas will be suspended, and on-site managers will be notified to take corresponding safety measures. Task priority adjustment: According to the urgency of tasks and the skill matching degree of workers, the construction sequence will be readjusted. For example, if a task in a high-risk area can be postponed, its priority will be lowered, and at the same time, workers will be transferred to low-risk areas to continue construction. Task assignment optimization: If some workers have multiple skills, they will be reassigned to currently executable tasks to avoid construction schedule delays caused by the suspension of construction in high-risk areas. For example, a worker originally responsible for electrical installation in a high-risk area can be transferred to a low-risk area for equipment installation after adjustment.
