[0030] Figure 1 FIG. 1 is a flowchart of the engineering construction safety monitoring method of the present application;

[0031] Figure 2 FIG. 1 is a flowchart of the engineering construction safety monitoring method of the present application; DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0033] In a feasible embodiment, referring to FIGS. 1, 2 and 3, Figure 1 and Figure 2 An engineering construction safety monitoring method, the engineering construction safety monitoring method comprising:

[0034] Step 101: Collect historical monitoring data of similar projects, including structural displacement values, stress values, environmental parameters, and accident records;

[0035] Step 102: Arrange multiple detection modules at key nodes of the construction site, and collect displacement deformation data, stress data, and environmental data of the building through the detection modules;

[0036] Step 103: Obtain displacement deformation data, stress data, and environmental data based on the risk feature analysis module to generate risk features;

[0037] Step 104: Train an LSTM prediction model based on historical monitoring data, input displacement deformation data, stress data, and environmental data to generate a safety threshold. When the risk characteristic exceeds the safety threshold, trigger a graded hazard warning message.

[0038] Step 105: Construct a three-dimensional model of the construction site through the BIM engine and display the danger warning information on the AR terminal.

[0039] Specifically, by collecting historical monitoring data from similar projects and using the LSTM model to train and predict the historical data, and inputting displacement deformation data, stress data, and environmental data, it is possible to generate warning thresholds for similar projects, thereby facilitating effective early warning and prevention of safety accidents.

[0040] Furthermore, through the detection module, multi-source detection is carried out on the construction site, so that various risks on the construction site can be coupled from multiple aspects, false alarms caused by single data can be eliminated, and early warning monitoring can be made more accurate. At the same time, by setting graded danger warning information, different early warning alarms are issued for different degrees of building deformation, so that more accurate judgments can be made on the deformation sites, and the buildings can be maintained and repaired while reducing losses. At the same time, a three-dimensional model of the construction site is constructed through the BIM engine, so that any part of the construction site can be quickly and accurately surveyed, so that the danger warning locations can be deployed in time for effective and rapid protection.

[0041] Specifically, in step 102, the detection module includes a displacement sensor, a stress sensor, an environmental temperature and humidity sensor, and an image acquisition module. The displacement sensor is used to monitor the displacement deformation data of the building, the stress sensor is used to monitor the stress data of the building, and the environmental data on site is monitored by the environmental humidity sensor, mainly including the temperature and humidity of the environment. The image acquisition module is used to identify the human portrait.

[0042] Specifically, in step 103, the risk feature analysis module obtains various data collected by the detection module in real time through the wireless transmission module, and generates risk features including:

[0043] Based on the YOLOV5 model, the image data is analyzed in real time to identify safety violations, that is, through image data monitoring, whether workers wear safety helmets and other behaviors, to protect the safety of workers;

[0044] Based on the wavelet denoising model, the displacement deformation data is wavelet denoised. Wavelet denoising can extract the true structure deformation signal from strong noise, provide pure data base for accurate early warning, reduce external dryness, and make the obtained displacement deformation data more accurate.

[0045] Based on the edge computing gateway, the stress data and environmental data are analyzed, combined with wavelet denoising, and the risk characteristic value is output. By analyzing the stress data and environmental data, the change value of stress and the thermal expansion and contraction caused by temperature change are measured, so that more accurate risk characteristic value is obtained, and more accurate data is provided for subsequent graded danger early warning information.

[0046] Specifically, the risk characteristic value calculation formula is:

[0047]

[0048] Where G represents the risk characteristic value, ΔF represents the change of stress per unit time, Δt represents the detection time interval, σ represents the standard dry strength of building materials, β represents the humidity sensitivity coefficient of building materials, RH represents the relative humidity, and RH0 represents the best humidity of building materials.

[0049] When the difference between the theoretical stress data and the measured actual stress data is less than 10%, then ΔF adopts the stress change of the actual stress data; when the difference between the theoretical stress data and the measured actual stress data is greater than 10%, then ΔF adopts the stress change of the theoretical stress data. Since the actual measured stress data will be disturbed by many factors, there is a certain difference between the actual stress, so the theoretical stress data is introduced. When calculating the risk characteristic value, dynamically select the theoretical stress data or the actual measured stress data, which can obtain more accurate risk characteristic value.

[0050] Further, the calculation formula of the theoretical stress data is:

[0051]

[0052] Where E represents the elastic modulus of the material, ΔL represents the change of the wavelet denoised displacement deformation data, and L0 represents the initial length of the building.

[0053] Specifically, when the monitoring object is steel, the E of the steel is 210 Gpa, the support length of the steel is 10 m, and the AL after the wavelet denoising processing is 1.2 mm, and the theoretical stress data is 25.2 Mpa, and when the measured stress data is between 22.6 Mpa and 26.4 Mpa, the measured stress data is brought into the risk characteristic value for calculation; when the measured stress data is less than 22.6 Mpa or greater than 26.4 Mpa, the theoretical stress data is brought into the risk characteristic value for calculation.

[0054] Specifically, in step 104, the safety threshold generated by training the LSTM prediction model based on the historical monitoring data can be more suitable for such engineering, thereby helping to effectively warn and prevent safety accidents. When different types of buildings are constructed, the historical monitoring data of different buildings needs to be collected to generate different safety thresholds.

[0055] Specifically, please refer to Figure 2 As shown in the figure, the hierarchical risk warning information includes:

[0056] When the risk characteristic value is less than or equal to 0.8 times the safety threshold, the construction is in a safe state at this time, and the construction is normal;

[0057] When the risk characteristic value is greater than 0.8 times the safety threshold and less than or equal to the safety threshold, start a first-level warning and issue a warning alarm;

[0058] When the risk characteristic value is greater than the safety threshold and less than or equal to 1.5 times the safety threshold, notify the person in charge and stop work in time for maintenance;

[0059] When the risk characteristic value is greater than or equal to 1.5 times the safety threshold, cut off the power and evacuate the workers in an emergency;

[0060] By setting the hierarchical risk warning information, accurate judgments can be made for different dangerous situations, and effective and rapid protection of the building can be achieved.

[0061] The embodiment of the application also provides a computer readable storage medium, which can be any available medium that can be stored by a computing device or a data storage device such as a data center containing one or more available media, which can be a magnetic medium (for example, a floppy disk, a hard disk, a magnetic tape), an optical medium (for example, a DVD), or a semiconductor medium (for example, a solid state disk), etc. The computer readable storage medium contains instructions for instructing the computing device to execute the aforementioned time synchronization method.

[0062] The embodiment of the present application further provides a computer program product containing instructions, which can be software or program product containing instructions, capable of running on a computing device or being stored in any available medium, and when the computer program product runs on the computing device, the computing device is caused to execute the foregoing time synchronization method
