Description

Technical Field

[0001] The invention belongs to the technical field of monitoring data analysis of hidden danger points in building construction, and relates to a method for monitoring data analysis of hidden danger points in building construction. Background Art

[0002] Hidden danger points in construction refer to various potential risk factors that may lead to safety accidents or engineering quality defects in the construction process. If these hidden danger points are not discovered and handled in a timely manner, they may lead to serious consequences, including but not limited to casualties, property losses, and project delays. Formwork engineering is an important part of construction. As an important part of concrete structure construction, it is directly related to the stability of the entire building structure and the life safety of construction workers. In recent years, safety accidents caused by quality problems in formwork engineering construction have occurred from time to time, causing huge losses to society and families. Therefore, the analysis method of monitoring data of hidden danger points in construction based on formwork engineering is of great significance and role.

[0003] The existing analysis method of monitoring data of hidden danger points in construction based on formwork engineering can basically meet the needs, but there are still certain shortcomings: on the one hand, the existing analysis method of monitoring data of hidden danger points in construction based on formwork engineering will monitor the formwork engineering after it is built and analyze whether it meets the requirements. However, the existing analysis method of monitoring data of hidden danger points in construction based on formwork engineering ignores the monitoring and analysis of its safety from multiple dimensions such as the formwork condition and support condition of the formwork engineering, so that potential construction hazards cannot be discovered in time, and the stability and safety of the supporting structure cannot be evaluated, which is not conducive to more accurate identification and resolution of safety hazards in construction, and the overall safety of the construction site cannot be guaranteed.

[0004] On the other hand, the existing analysis method of monitoring data of hidden danger points in construction based on formwork engineering monitors and analyzes the formwork engineering during the pouring of concrete structure to prevent safety accidents. However, the existing analysis method of monitoring data of hidden danger points in construction based on formwork engineering ignores the monitoring and analysis of the formwork engineering during the construction process from multiple angles such as inclination, displacement, and deformation, so that problems and bottlenecks in the construction process cannot be discovered in time, and targeted measures cannot be taken to solve them. It is also not conducive to timely discovering and handling potential safety problems, reducing the probability of safety accidents, and ensuring the life safety and property safety of construction personnel. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a method for analyzing data of monitoring hidden danger points in construction is now proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides a method for analyzing monitoring data of hidden danger points in construction, including: S1.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 As shown, the present invention provides a method for analyzing monitoring data of hidden danger points in construction, and the specific steps are as follows: S1. Acquisition of basic monitoring data: Recording each hidden danger point of the target type to be monitored as each designated hidden danger point in construction, and acquiring the template basic monitoring data and supporting basic monitoring data of each designated hidden danger point in construction.

[0020] As a preferred feasible embodiment, the basic monitoring data of the template of each designated construction hazard point includes the verticality of each vertical pole, the distance between each vertical pole, the pitch of each horizontal pole and the inclination angle of each scissors brace.

[0021] It is necessary to further explain that the verticality of each vertical pole, the spacing between each vertical pole, the pitch of each horizontal pole and the inclination angle of each scissors brace are used as the basic monitoring data of the formwork at each designated construction hazard point because: (1) The verticality of each vertical pole is directly related to the overall stability of the formwork project. Excessive verticality deviation will cause uneven force on the vertical pole and generate bending moment, thereby reducing the bearing capacity and stability of the formwork project.

[0022] (2) The spacing between each column is the distance between two columns in the formwork project with the set starting column as the starting point and the end point, as shown in the following figure. Figure 2As shown. The size of the pole spacing directly affects the bearing capacity of the formwork project. If the spacing is too large, the number of poles per unit area will be reduced, thereby reducing the overall stiffness and bearing capacity of the formwork project. Reasonable pole spacing can ensure that the structure maintains sufficient stability and stiffness when bearing construction loads, and prevent structural deformation or collapse caused by excessive spacing.

[0023] (3) The pitch of each horizontal bar is the distance between two horizontal bars in the formwork project, with the horizontal bar closest to the ground as the starting bar and the horizontal bar farthest from the ground as the ending bar. Figure 2 As shown in the figure. The horizontal bar is the key component connecting the vertical bars. Its pitch, that is, the distance between adjacent horizontal bars, directly affects the overall stability of the formwork project. If the pitch is too large, the lateral stability of the system will be weakened and the risk of collapse will increase. The horizontal bar also plays the role of evenly transferring the construction load to the vertical bars. A reasonable pitch can ensure even transfer of load and avoid local stress concentration.

[0024] (4) The inclination angle of each scissors brace is the angle of each scissors brace in the formwork engineering relative to the ground. The scissors brace is an important lateral force resisting component in the formwork engineering, and its inclination angle directly affects the lateral force resistance performance of the formwork engineering. An unreasonable inclination angle will reduce the system's wind resistance, earthquake resistance and other capabilities. The setting of the scissors brace can enhance the overall stiffness and stability of the formwork engineering and prevent the structure from being excessively deformed when subjected to lateral forces.

[0025] It needs to be further explained that the specific method for obtaining the verticality of each upright pole of the template of each designated construction hazard point, the spacing between each upright pole, the pitch of each horizontal pole and the inclination angle of each scissors brace is: using a theodolite to measure the deviation angle of each upright pole of the template of each designated construction hazard point from the vertical direction, and further subtracting ninety degrees from the deviation angle of each upright pole of the template of each designated construction hazard point from the vertical direction, and recording the difference as the verticality of each upright pole of the template of each designated construction hazard point.

[0026] The distance between two vertical poles of the template at each designated construction potential hazard point is directly detected by using a laser rangefinder to obtain the distance between the vertical poles of the template at each designated construction potential hazard point.

[0027] A reference point is set up at the construction site of each designated construction hazard point, and the elevation of the reference point is measured with a level. Then, a ruler is placed on horizontal bars at different heights, and the elevation values ​​on the ruler are read. The difference between the elevations of adjacent horizontal bars is further calculated and recorded as the pitch of each horizontal bar of the template of each designated construction hazard point.

[0028] Select a suitable length of each scissors brace of the template at each designated construction hazard point, straighten it along the direction of the scissors brace with a thin rope, align the bottom edge of the protractor with the ground, then place the thin rope against the edge of the protractor, and read the angle value displayed on the protractor, which is the inclination angle of each scissors brace of the template at each designated construction hazard point.

[0029] The basic monitoring data of the support of each designated construction potential hazard point includes the axial stress, lateral stress and inclination angle of each diagonal support rod.

[0030] It is necessary to further explain that the reason for using the axial stress, transverse stress and inclination angle of each diagonal brace as the basic monitoring data for supporting the potential danger points of each designated construction project is as follows: (1) Axial stress refers to the stress along the axis of an object. When the diagonal brace is subjected to axial pressure or tension, its stress state directly affects the stability of the structure. If the axial stress exceeds the allowable range of the material or design, it may cause the diagonal brace to be damaged, thereby affecting the safety of the overall structure.

[0031] (2) Transverse stress refers to the stress acting on the cross section of an object, that is, the stress perpendicular to the axis of the object. Excessive transverse stress can cause bending deformation of the diagonal brace, reduce its bearing capacity, and even cause structural instability.

[0032] (3) The inclination angle of the diagonal brace refers to the angle between it and the ground. The inclination angle of the diagonal brace directly affects its force-bearing performance and stability. If the inclination angle is too large or too small, it may cause uneven force on the diagonal brace and increase the risk of structural damage.

[0033] It needs to be further explained that the specific method of obtaining the axial stress, lateral stress and inclination angle of each diagonal brace at each designated construction hazard point is: using the deployed multi-axis stress sensors to directly measure the axial stress and lateral stress of each diagonal brace at each designated construction hazard point.

[0034] The electronic inclinometer is used to measure the angle between each diagonal brace at each designated construction potential hazard point and the ground to obtain the inclination angle of each diagonal brace at each designated construction potential hazard point.

[0035] S2. Analysis of basic monitoring data: Analyze the existence of formwork hazards and support hazards at each designated construction hazard point.

[0036] As a preferred feasible embodiment, the existence of template hidden dangers at each designated construction hidden danger point is described, and the specific analysis method includes: extracting the verticality and spacing of each upright pole of the template at each designated construction hidden danger point, analyzing the safety index of the upright pole of the template at each designated construction hidden danger point , , The numbers of the designated construction hazards are: The number of potential danger points in a designated building construction.

[0037] Extract the horizontal bar pitch and the inclination angle of each scissors support of the template of each designated construction hazard point, and record them as ,in , is the number of each horizontal bar step, is the number of horizontal rod steps, , is the number of each scissors support, is the number of scissors braces.

[0038] Analyze the template safety indicators of each designated construction potential risk point ,in are the standard horizontal rod step lengths extracted from the database, Extracted from the database The first template of the designated construction hazard point The standard tilt angle of the scissors support is: They are the allowable difference between the set horizontal rod pitch and the standard horizontal rod pitch, and the allowable difference between the inclination angle of the scissors support and the standard inclination angle.

[0039] In a feasible specific example, the allowable difference between the set horizontal rod step and the standard horizontal rod step, and the allowable difference between the tilt angle of the scissors brace and the standard tilt angle can be set to 0.01 meters and 0.01 degrees respectively. This means that the horizontal rod step and the standard horizontal rod step, and the tilt angle of the scissors brace and the standard tilt angle can have a deviation of 1%.

[0040] The template safety index of each designated construction potential hazard point is compared with the preset template safety index threshold. If the template safety index of a designated construction potential hazard point is greater than or equal to the template safety index threshold, the template potential hazard existence situation of the designated construction potential hazard point is recorded as no potential hazard. Otherwise, the template potential hazard existence situation of the designated construction potential hazard point is recorded as potential hazard. Then the template potential hazard existence situation of each designated construction potential hazard point is obtained.

[0041] As a preferred feasible embodiment, the safety index of the vertical poles of the templates at the designated construction potential hazard points is specifically analyzed by extracting the verticality and spacing of the vertical poles of the templates at the designated construction potential hazard points, and recording them as ,in , is the number of each pole, is the number of poles, , is the number of the distance between each pole, The number of pole spacings is used to analyze the pole safety index of the template at each designated construction hazard point. ,in are the verticality threshold of the poles and the standard pole spacing extracted from the database, It is the allowable difference between the set pole spacing and the standard pole spacing.

[0042] In a specific feasible example, the allowable difference between the set vertical pole spacing and the standard vertical pole spacing can be set to 0.01 meters, which means that a deviation of one percent is allowed between the vertical pole spacing and the standard vertical pole spacing.

[0043] As a preferred feasible embodiment, the specific analysis method of the existence of support hazards at each designated construction hazard point includes: extracting the axial stress, lateral stress and inclination angle of each diagonal brace at each designated construction hazard point, and recording them as ,in , is the number of each diagonal brace, is the number of diagonal braces, and the support safety index of each designated construction hazard point is analyzed ,in The first The first designated construction hazard point The standard axial stress, standard transverse stress and standard inclination angle of each diagonal brace are They are the allowable difference between the axial stress of the diagonal brace and the standard axial stress, the allowable difference between the transverse stress and the standard transverse stress, and the allowable difference between the inclination angle and the standard inclination angle. is a natural constant.

[0044] In a feasible specific example, the set allowable difference between the axial stress of the diagonal brace and the standard axial stress, the allowable difference between the transverse stress and the standard transverse stress, and the allowable difference between the tilt angle and the standard tilt angle can be set to 0.01 Pascal, 0.01 Pascal, and 0.01 degree, respectively. This means that the allowable difference between the axial stress of the diagonal brace and the standard axial stress, the allowable difference between the transverse stress and the standard transverse stress, and the tilt angle and the standard tilt angle can all have a deviation of 1%.

[0045] The existence of support hazards at each designated construction hazard point can be obtained in the same way as the existence of template hazards at each designated construction hazard point.

[0046] It needs to be further explained that the specific method of obtaining the existence of support hazards at each designated construction hazard point is: comparing the support safety index of each designated construction hazard point with the preset support safety index threshold; if the support safety index of a designated construction hazard point is greater than or equal to the support safety index threshold, then the existence of support hazards at the designated construction hazard point is recorded as no hazards; otherwise, the existence of support hazards at the designated construction hazard point is recorded as hazards, thereby obtaining the existence of support hazards at each designated construction hazard point.

[0047] The present invention helps to timely discover potential construction hazards by analyzing the existence of template hazards and support hazards at each designated construction hazard point, so as to take timely remedial measures to avoid accidents, help evaluate the stability and safety of the supporting structure, and timely warn of possible support failure problems, which is conducive to more accurately identifying and resolving safety hazards in construction, reducing the incidence of safety accidents and improving the overall safety of the construction site.

[0048] S3. Acquisition of construction process monitoring data: The construction process of pouring concrete structure at each designated construction potential hazard point is recorded as the construction process of each designated construction potential hazard point, and the construction process of each designated construction potential hazard point is further monitored to obtain the construction process monitoring data of each designated construction potential hazard point.

[0049] The construction process monitoring data of each designated construction potential hazard point includes template monitoring data and support monitoring data.

[0050] Among them, the formwork monitoring data includes the inclination, displacement, deformation, leakage and formwork explosion of the formwork.

[0051] It is necessary to further explain that the reason for using the template's inclination, displacement, deformation, leakage and explosion as template monitoring data during the construction process of each designated construction risk point is: (1) The template's inclination directly affects the molding quality of the concrete structure. If the template has a problem of excessive inclination during the construction process, it will cause the concrete structure to tilt, twist and other problems, and will also affect the stability and safety of the entire building. By monitoring the template's inclination, the template's position and posture can be adjusted in time to ensure that the verticality and horizontality of the concrete structure meet the design requirements.

[0052] (2) During the construction process, the formwork may be affected by various external forces, such as lateral pressure during concrete pouring and wind force, which may cause the formwork to move. If the displacement is too large, it will affect the dimensional accuracy and shape of the concrete structure and may even cause structural damage. Therefore, monitoring the displacement of the formwork can timely detect and correct the displacement problem and ensure the accuracy and stability of the concrete structure.

[0053] (3) The formwork may deform when it is subjected to pressure and vibration during concrete pouring. If the deformation is too large, it will lead to problems such as uneven surface and inaccurate dimensions of the concrete structure. By monitoring the deformation of the formwork, the bearing capacity and stability of the formwork can be evaluated, and timely measures can be taken to prevent excessive deformation of the formwork and ensure the construction quality of the concrete structure.

[0054] (4) If the formwork is not tightly spliced ​​or the joints are improperly handled, it is easy to cause leakage during concrete pouring. Leakage not only causes waste of concrete materials, but also affects the strength and durability of the concrete structure. Monitoring the leakage of the formwork can timely detect and repair the leakage site, ensuring the integrity and quality of the concrete structure.

[0055] (5) Formwork burst refers to the phenomenon that the formwork suddenly breaks or deforms seriously when it is under the pressure of concrete pouring. This is usually caused by unreasonable formwork design, poor production quality, improper installation or too fast concrete pouring speed. Formwork burst can cause serious damage to the concrete structure and even cause safety accidents. Therefore, taking formwork burst as one of the monitoring data can timely detect and prevent the occurrence of formwork burst phenomenon and ensure construction safety and quality.

[0056] It needs to be further explained that the specific method of obtaining the inclination, displacement, deformation, leakage and burst of the formwork during the construction process of each designated construction potential hazard point is: installing inclination sensors at key parts of the formwork, and using the deployed inclination sensors to directly detect the inclination of the formwork during the construction process of each designated construction potential hazard point.

[0057] A displacement sensor is installed between the fixed position of the template and a relatively stable reference point, and the displacement of the template during the construction process of each designated construction hazard point is directly measured using the deployed displacement sensor.

[0058] The deployed 3D laser scanner is used to perform real-time scanning of the templates during the construction process of each designated construction potential hazard point to obtain the 3D data of the templates during the construction process of each designated construction potential hazard point, and professional software is used to construct it to obtain a 3D visualization model of the templates during the construction process of each designated construction potential hazard point, which is then overlapped and compared with the standard 3D visualization model of the templates for each designated construction potential hazard point stored in the database to obtain the degree of overlap between the 3D visualization model of the templates during the construction process of each designated construction potential hazard point and its standard 3D visualization model, and further 1 is subtracted from the degree of overlap between the 3D visualization model of the templates during the construction process of each designated construction potential hazard point and its standard 3D visualization model, and the difference obtained is recorded as the deformation degree of the templates during the construction process of each designated construction potential hazard point.

[0059] The templates during the construction process of each designated construction potential hazard point are photographed by the deployed high-definition cameras to obtain images of the templates during the construction process of each designated construction potential hazard point, which are then matched with the leakage images and mold explosion images stored in the database to obtain the leakage and mold explosion of the templates during the construction process of each designated construction potential hazard point.

[0060] The support monitoring data includes the displacement, deformation and vibration amplitude of each diagonal support rod.

[0061] It should be further explained that the reason for using the displacement, deformation and vibration amplitude of each diagonal brace as the support monitoring data during the construction process of each designated construction risk point is: (1) The displacement of the diagonal brace is an important indicator for evaluating its stability. During the construction process, the diagonal brace may be displaced due to load changes, foundation settlement or external factors. Excessive displacement may cause the support system to become unstable, thereby affecting the safety of the overall structure. Therefore, by monitoring the displacement, it is possible to timely detect and take measures to prevent the diagonal brace from being displaced too much, thereby ensuring safety during the construction process.

[0062] (2) It is normal for the diagonal brace to deform to a certain extent when bearing loads. However, if the deformation is too large, it may mean that the bearing capacity of the diagonal brace has reached its limit or there are other potential problems. By monitoring the deformation, the working status of the diagonal brace can be evaluated and potential safety hazards can be discovered and dealt with in a timely manner.

[0063] (3) During the construction process, especially during concrete pouring and vibration operations, certain vibrations will be generated. If the diagonal brace is subjected to excessive vibration, it may become loose, break, or collide with other components, thus causing a safety accident. Therefore, monitoring the vibration amplitude can help us understand the performance of the diagonal brace in a vibration environment and take timely measures to reduce the adverse effects of vibration on it.

[0064] It needs to be further explained that the specific method for obtaining the displacement, deformation and vibration amplitude of each diagonal brace during the construction process of each designated construction potential hazard point is: the displacement and deformation of each diagonal brace during the construction process of each designated construction potential hazard point can be obtained by the same method as the method for obtaining the displacement and deformation of the template during the construction process of each designated construction potential hazard point.

[0065] The vibration amplitude of each diagonal brace during the construction process of each designated building construction hazard point is directly detected by using the deployed vibration sensors.

[0066] S4. Construction process monitoring data analysis: Analyze the existence of hidden dangers in the construction process of each designated construction site.

[0067] As a preferred feasible embodiment, in the process of analyzing the hidden dangers in the construction process of each designated construction hidden danger point, it is necessary to construct the construction process safety index of each designated construction hidden danger point, and the specific analysis method includes: extracting the inclination angle, displacement, deformation, leakage and explosion of the template of each designated construction hidden danger point, analyzing the template safety evaluation index of each designated construction hidden danger point .

[0068] Extract the displacement, deformation and vibration amplitude of each diagonal brace at each designated construction hazard point, and analyze the support safety evaluation index of each designated construction hazard point .

[0069] Analyze the construction process safety indicators of each designated construction hidden danger point ,in They are the weight coefficients of the construction process safety indicators corresponding to the set formwork hidden danger evaluation index and support hidden danger evaluation index respectively.

[0070] In a feasible specific example, the weight coefficients of the construction process safety index corresponding to the set formwork hidden danger evaluation index and support hidden danger evaluation index are set to 0.6 and 0.4 respectively.

[0071] As an important part of the construction process, the stability and safety of the formwork are directly related to the stability and bearing capacity of the entire structure. The existence of hidden dangers in the formwork may lead to quality problems during the concrete pouring process and even cause safety accidents. Therefore, the formwork hidden danger evaluation index has a high weight in the overall construction safety assessment.

[0072] Although the support system also plays an important role in construction, providing the necessary support and stability for the formwork and structure, its main role is auxiliary. Compared with the hidden dangers of formwork, the direct impact of hidden dangers of support may be relatively small, but it still needs to be given enough attention.

[0073] The weight coefficients of the construction process safety indicators corresponding to the template hidden danger evaluation index and the support hidden danger evaluation index are set to 0.6 and 0.4 respectively, which can ensure the accuracy and rationality of the overall construction safety assessment. This allocation method not only highlights the importance of template hidden dangers, but also takes into account the prevention and control needs of support hidden dangers.

[0074] As a preferred feasible embodiment, the specific method for obtaining the existence of hidden dangers in the construction process of each designated construction hidden danger point includes: comparing the construction process safety index of each designated construction hidden danger point with the preset construction process safety index threshold value; if the construction process safety index of a designated construction hidden danger point is greater than or equal to the construction process safety index threshold value, then the existence of hidden dangers in the construction process of each designated construction hidden danger point is recorded as a situation where there are no hidden dangers; otherwise, the existence of hidden dangers in the construction process of each designated construction hidden danger point is recorded as a situation where there are hidden dangers, thereby obtaining the existence of hidden dangers in the construction process of each designated construction hidden danger point.

[0075] As a preferred feasible embodiment, the template safety evaluation index of each designated construction potential hazard point is specifically analyzed by extracting the inclination angle, displacement, deformation, grout leakage and template explosion of each designated construction potential hazard point, and recording them as , analyze the template safety evaluation index of each designated construction potential hazard point ,in They are the allowable inclination angle, allowable displacement and allowable deformation of the template at the preset construction risk point. are the and symbol and the or symbol respectively.

[0076] It needs to be further explained that Indicates There is leakage in the formwork of the designated construction potential hazard point. Indicates The templates at the designated construction potential hazard points do not have any leakage. Indicates There is a situation where the formwork at the designated construction site has a potential danger point. Indicates There is no possibility of formwork explosion at the designated construction potential hazard points.

[0077] As a preferred feasible embodiment, the support safety evaluation index of each designated construction potential hazard point is specifically analyzed by extracting the displacement, deformation and vibration amplitude of each diagonal brace at each designated construction potential hazard point, and recording them as ,in , is the number of each diagonal brace, is the number of diagonal braces, and the support safety evaluation index of each designated construction hazard point is analyzed. ,in are the permissible displacement, permissible deformation and permissible vibration amplitude of the diagonal brace at the preset construction hazard point. is a natural constant.

[0078] The present invention analyzes the existence of hidden dangers in the construction process of each designated construction hidden danger point, which helps to timely discover problems and bottlenecks in the construction process based on the analysis results of monitoring data, and then take targeted measures to solve them. It is also beneficial to timely discover and deal with potential safety problems, reduce the probability of safety accidents, and protect the life safety and property safety of construction personnel.

[0079] S5. Analysis of hidden danger points in construction: The existence of hidden dangers in formwork, support and construction process at each designated hidden danger point in construction are collectively referred to as the hidden danger conditions at each designated hidden danger point in construction, and they will be fed back and processed.

[0080] As a preferred feasible embodiment, the specific operations of feedback and processing the hidden danger conditions of each designated construction hidden danger point include: extracting the existence of template hidden dangers, support hidden dangers and construction process hidden dangers of each designated construction hidden danger point; if the template hidden danger condition of a designated construction hidden danger point is that there is a hidden danger, or its support hidden danger condition is that there is a hidden danger, or its construction process hidden danger condition is that there is a hidden danger, then the number and cause of the hidden danger of the designated construction hidden danger point will be fed back.

[0081] Further, based on the existence of template hazards, support hazards and construction process hazards at the designated construction hazard point, the causes of the hazards are analyzed and targeted treatment measures are formulated.

[0082] It needs to be further explained that the specific content of the analysis of the causes of hidden dangers at the designated construction site includes: if there are template hidden dangers, support hidden dangers and construction process hidden dangers at the designated construction site, the detailed situation of the hidden dangers at the designated construction site will be further fed back to the project management, supervision unit and relevant regulatory departments through on-site inspections, monitoring data analysis and expert evaluation.

[0083] The specific contents of the targeted treatment measures include: (1) Measures to be taken when hidden dangers of formwork exist: Check the condition of formwork materials, and immediately replace or repair formwork materials that do not meet the requirements. Strengthen the support and reinforcement of the formwork during the installation of the formwork project.

[0084] (2) Check the stability of the formwork support system to ensure that the support system meets the design requirements and is free of missing parts, looseness, and deformation.

[0085] (3) Strengthen supervision and inspection of the construction process to ensure that construction personnel comply with operating procedures and safety regulations.

[0086] The present invention provides feedback and processing of hidden dangers at designated construction sites. By timely feedback of hidden dangers, measures can be taken immediately to control risks and prevent hidden dangers from further expanding or evolving into safety accidents, which helps to reduce the time and cost of accident handling and is also beneficial to protecting the physical health and life safety of construction workers.

As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
