DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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] Example 1: Please refer to Figure 1-Figure 4 As shown, the technical solution provided by the present invention is: a real-time construction safety prediction method, in this embodiment, it is used to monitor the construction project in real time and perform safety analysis on its status, so as to achieve safety prediction of the construction. In this embodiment, the preferred construction project is the road at the construction site; In this embodiment, the real-time construction safety prediction method is as follows: Step S1, obtaining construction data of different construction projects, and setting construction monitoring criteria for different construction projects based on the construction data; It should be noted that the construction data specifically refers to the number of construction accidents of the same type of construction projects and the increased construction costs and construction delays caused by the construction accidents; In this embodiment, step S1 includes the following sub-steps: Step S11, obtaining the number of construction accidents of different construction projects, and marking the number of construction accidents as SGi, where i is the number of the construction project; Step S12, obtaining the increased construction costs caused by each construction accident of different construction projects, traversing and comparing the increased construction costs caused by each construction accident, obtaining the maximum value of the increased construction costs, and taking the maximum value of the increased construction costs as the increased construction costs CBi of different construction projects; Step S13, similarly, obtain the construction delay period caused by each construction accident of different construction projects, traverse and compare the construction delay period caused by each construction accident, obtain the maximum value of the construction delay period, and use the maximum value of the construction delay period as the construction project delay period YWi of different construction projects; Step S14, substituting the above three groups of parameters into the calculation formula, and calculating the construction monitoring values ​​SJi of different construction projects through the calculation formula, the specific calculation formula is as follows: SJi=SGi×a1+CBi×a2+YWi×a3, where a1, a2 and a3 are weight coefficients, and a1<a2<a3; Step S15, obtaining construction monitoring criteria corresponding to different construction projects according to the construction monitoring values, specifically: If the construction monitoring value exceeds the construction monitoring threshold, the construction monitoring criteria corresponding to the construction project are: local monitoring; If the construction monitoring value does not exceed the construction monitoring threshold, the construction monitoring criteria corresponding to the construction project are: global monitoring; It should be explained that local monitoring refers to monitoring key areas in a construction project, while global monitoring refers to comprehensive monitoring of all areas in a construction project; Step S2, performing safety monitoring on the construction project during the waiting period, and obtaining deformation data and image data at a fixed acquisition cycle; The waiting period is the time from the end of a construction project to the start of the next construction project. For example, after pouring concrete on a road, it takes a week to lay permeable bricks. In this case, the waiting period is one week. The collection period is preferably daily in the embodiment. Figure 2 As shown, the deformation data are the lateral and longitudinal values ​​at different collection periods of the construction project, and the image data are real-time images at different collection periods of the construction project. Specifically, the deformation data is measured after the mold is disassembled, the longitudinal value is the convex height of the convexity or the concave depth of the concave on the road surface, and the lateral value is the convex height of the convexity or the concave depth of the concave on both sides. The lateral value may be caused by squeezing the molds on both sides during the construction and pouring of concrete, and the longitudinal value may be caused by objects falling during construction or uneven concrete pouring during construction. In specific implementation, the horizontal and vertical values ​​of the edge parts of the construction project during the waiting period can be measured by a level meter, and real-time images can be obtained by aerial photography using a drone.

[0020] Step S3, obtaining the safety impact value of the construction project in the current collection period based on deformation data and image data analysis; In this embodiment, step S3 includes the following sub-steps: Step S301, obtaining a real-time image corresponding to a previous acquisition cycle of a construction project, binarizing the real-time image, and obtaining a binarized image of the real-time image corresponding to the construction project; Step S302, using the existing technology to identify whether there are cracks in the binary image, if there are no cracks, no operation is performed, if there are cracks, then proceed to the next step; In practice, by extracting pixel information of the binary image, if there is no crack on the road, the pixel information of the binary image is consistent, if there is a crack on the road, the pixel information of the binary image is inconsistent, and the pixel points that are different from the majority are connected one by one to obtain the crack. In practice, the method can also be used to identify the bulge or depression on the road; Step S303, as Figure 3 and Figure 4 As shown, four groups of straight lines are drawn around the edge of the crack. The enclosed area of ​​the crack is obtained after the four groups of straight lines intersect. The enclosed area is the area where the crack affects the quality of the construction project. Step S304, calculating the area of ​​the quality impact region by using an area formula, and obtaining the historical quality impact area of ​​the cracks in the real-time image corresponding to the previous acquisition cycle of the construction project; Step S305, similarly, obtain the real-time image corresponding to the current acquisition period of the construction project, and obtain the real-time quality impact area of ​​the cracks in the real-time image corresponding to the current acquisition period of the construction project according to steps S301 to S304; Step S306, comparing the real-time quality impact area of ​​the same crack with the historical quality impact area; If the real-time quality impact area is equal to the historical quality impact area, the quality impact expansion value of the current collection cycle of the construction project is zero; If the real-time quality impact area is larger than the historical quality impact area, the real-time quality impact area is subtracted from the historical quality impact area to obtain the impact area change value of the crack in the real-time image corresponding to the current acquisition period of the construction project; Step S307, traverse and compare the influence area change values ​​of the cracks in the real-time image corresponding to the current acquisition period of the construction project, obtain the maximum value of the influence area change value, and use the maximum value of the influence area change value as the quality impact expansion value ZJi of the current acquisition period of the construction project; Here we only need to count the cracks that affect the regional change value, and then find the maximum value; Step S308, at the same time, the real-time quality impact areas of all cracks in the real-time image corresponding to the current acquisition period of the construction project are added together to obtain the total quality impact area MJi of the construction project in the current acquisition period; Step S309, the first safety impact value Y1i of the construction project in the current collection period is calculated by the formula Y1i=ZJi×b1+MJi×b2; wherein b1 and b2 are weight coefficients; In this embodiment, step S3 further includes the following sub-steps: Step S311, obtaining the vertical value of the convexity or concavity of the construction project in the previous collection cycle, and then obtaining the vertical value of the convexity or concavity of the construction project in the current collection cycle; Step S312: if the longitudinal value of the same bulge or the same depression changes, the longitudinal value of the bulge in the previous acquisition cycle is subtracted from the longitudinal value of the bulge in the current acquisition cycle, or the longitudinal value of the depression in the current acquisition cycle is subtracted from the longitudinal value of the depression in the previous acquisition cycle to obtain a longitudinal change value, and the longitudinal change values ​​are traversed and compared to obtain the maximum value of the longitudinal change values, and the maximum value of the longitudinal change values ​​is used as the longitudinal deformation value ZXi of the current acquisition cycle of the construction project; If the longitudinal value of the same convexity or the same concavity does not change, the longitudinal deformation value of the current collection period of the construction project is zero; Step S313: Similarly, according to steps S311 to S312, the lateral deformation value HXi of the current collection period of the construction project is obtained; Step S314, the second safety impact value Y2i of the construction project in the current collection period is calculated by the formula Y2i=(HXi+ZXi)×e; wherein e is a natural constant.

[0021] Step S4, predicting the construction safety of the construction project through the safety impact value; In this embodiment, step S4 includes the following sub-steps: Step S41, obtaining the first safety impact value Y1i and the second safety impact value Y2i of the construction project in the current collection period; Step S42, using the formula AQi=1 / (Y1i×c1+Y2i×c2) to calculate the construction safety value AQi of the construction project in the current collection period; where c1 and c2 are proportional coefficients, c1=c2; Step S43, obtaining a corresponding construction safety threshold according to the construction project; The construction safety threshold is set according to the purpose of the construction project. For example, when the construction project is a road, the construction safety threshold is 50, and when the construction project is a load-bearing column, the construction safety threshold is 100. The data here is only for ease of understanding and has no actual reference significance; Step S44, if the construction safety value is less than the corresponding construction safety threshold, predict and generate a construction abnormality signal; If the construction safety value is greater than or equal to the corresponding construction safety threshold, a normal construction signal is predicted to be generated.

[0022] The present invention adopts the technical solution in this embodiment, and can set construction monitoring criteria for different construction projects based on construction data. At the same time, when conducting safety monitoring on construction projects during the waiting period, deformation data and image data are obtained by monitoring with a fixed collection cycle, so as to obtain the safety impact value of the construction project in the current collection cycle based on the deformation data and image data analysis, and finally predict the construction safety of the construction project through the safety impact value, and realize intelligent and accurate prediction of construction safety through data analysis.

[0023] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.

[0024] Example 2: Figure 5 As shown, based on another concept of the same invention, a real-time construction safety prediction system is proposed, comprising: The first acquisition module is used to obtain construction data of different construction projects; Criteria establishment module: used to set construction monitoring criteria for different construction projects based on construction data; In this embodiment, the criteria establishment module includes the following working process: Obtain the number of construction accidents for different construction projects, and then obtain the increased construction costs caused by each construction accident for different construction projects, traverse and compare the increased construction costs caused by each construction accident, obtain the maximum value of the increased construction costs, and use the maximum value of the increased construction costs as the increased construction costs of different construction projects. Similarly, obtain the construction delay period caused by each construction accident for different construction projects, traverse and compare the construction delay period caused by each construction accident, obtain the maximum value of the construction delay period, and use the maximum value of the construction delay period as the construction delay period of different construction projects, calculate the construction monitoring values ​​of different construction projects, and obtain the corresponding construction monitoring criteria for different construction projects based on the construction monitoring values; The second acquisition module is used to perform safety monitoring on the construction project during the waiting period, and to obtain deformation data and image data at a fixed acquisition cycle.

[0025] A data analysis module is used to obtain the safety impact value of the construction project in the current collection period based on deformation data and image data analysis; In this embodiment, the data analysis module includes the following analysis process: Get the real-time image corresponding to the last acquisition cycle of the construction project, binarize the real-time image, get the binarized image of the real-time image corresponding to the construction project, identify whether there is a crack in the binarized image, if there is no crack, do not perform any operation, if there is a crack, draw four groups of straight lines around the edge of the crack, the four groups of straight lines intersect to get the enclosed area of ​​the crack, the enclosed area is the quality impact area of ​​the crack on the construction project, calculate the area of ​​the quality impact area by the area formula, get the historical quality impact area of ​​the crack in the real-time image corresponding to the last acquisition cycle of the construction project, similarly, get the real-time image corresponding to the current acquisition cycle of the construction project, and get the real-time quality impact area of ​​the crack in the real-time image corresponding to the current acquisition cycle of the construction project according to the above steps, and compare the real-time quality impact area of ​​the same crack with the historical quality impact area. Compare, if the real-time quality impact area is equal to the historical quality impact area, then the quality impact expansion value of the current acquisition cycle of the construction project is zero; if the real-time quality impact area is greater than the historical quality impact area, then the real-time quality impact area is subtracted from the historical quality impact area to obtain the impact area change value of the cracks in the real-time image corresponding to the current acquisition cycle of the construction project; traverse and compare the impact area change values ​​of the cracks in the real-time image corresponding to the current acquisition cycle of the construction project to obtain the maximum value of the impact area change value, and use the maximum value of the impact area change value as the quality impact expansion value of the current acquisition cycle of the construction project; at the same time, add and sum the real-time quality impact areas of all cracks in the real-time image corresponding to the current acquisition cycle of the construction project to obtain the total quality impact area of ​​the construction project in the current acquisition cycle, and calculate the first safety impact value of the construction project in the current acquisition cycle; In this embodiment, the data analysis module also includes the following analysis process: Obtain the longitudinal value of the bulge or depression of the construction project in the previous collection cycle, and then obtain the longitudinal value of the bulge or depression of the construction project in the current collection cycle. If the longitudinal value of the same bulge or the same depression changes, subtract the longitudinal value of the bulge in the previous collection cycle from the longitudinal value of the bulge in the current collection cycle, or subtract the longitudinal value of the depression in the current collection cycle from the longitudinal value of the depression in the previous collection cycle to obtain the longitudinal change value. Traverse and compare the longitudinal change values ​​to obtain the maximum value among the longitudinal change values, and use the maximum value among the longitudinal change values ​​as the longitudinal deformation value of the construction project in the current collection cycle. If the longitudinal value of the same bulge or the same depression does not change, the longitudinal deformation value of the construction project in the current collection cycle is zero. Similarly, according to the above steps, the lateral deformation value of the construction project in the current collection cycle is obtained, and the second safety impact value of the construction project in the current collection cycle is calculated.
