Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a BIM-based bridge mass concrete temperature monitoring method and system. Background Art

[0002] Temperature monitoring of large-volume concrete structures is a crucial link in bridge engineering. During the pouring and hardening process of large-volume concrete, a large amount of heat is generated by the cement hydration reaction, causing the temperature inside the concrete to rise sharply. If the temperature is not properly controlled, the large temperature difference between the inside and outside of the concrete will produce temperature stress, leading to the formation of cracks, affecting the durability and safety of the structure. At the same time, it not only affects the appearance, but may also extend to the inside of the structure, weakening the bearing capacity of the bridge.

[0003] In the monitoring process of related technologies, manual experience judgment is used, which leads to large deviations in the temperature monitoring of large-volume concrete and is relatively cumbersome.

[0024] Figure 1 A flow chart of a BIM-based bridge mass concrete temperature monitoring method proposed in an embodiment of the present application. DETAILED DESCRIPTION

[0025] 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 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.

[0026] Building Information Modeling (BIM) technology uses three-dimensional modeling and information integration, and can transmit sensor data to the BIM platform in real time through the Internet of Things (IoT) technology to achieve continuous monitoring.

[0027] This application embodiment proposes a BIM-based bridge mass concrete temperature monitoring method, please refer to Figure 1 , the method comprises the following steps: S101: Obtain a bridge model based on BIM, and determine a concrete model based on the bridge model.

[0028] Optionally, in this embodiment, the bridge model can be divided according to material type based on the material classification window of the BIM software to form multiple modules, retain the modules with the material label "concrete", and discard the remaining modules. Then, all modules with the material label "concrete" are obtained and combined according to the original spatial position to form a concrete model.

[0029] Optionally, in this embodiment, the bridge model can be divided according to material type based on the material classification window of the BIM software to form multiple modules, retain the modules with the material label "concrete", and discard the remaining modules. Then, all modules with the material label "concrete" are obtained and combined according to the original spatial position to form a concrete model.

[0030] As can be understood, the material classification function of the BIM software is used to divide the bridge model by material type to generate multiple modules. Each module corresponds to a material type. All modules with the material label "concrete" are obtained and combined according to their spatial positions in the original model to form a complete concrete model.

[0031] S102: Determine the surface of the concrete model, extend the target distance L1 into the concrete model based on the surface, and extend in a direction perpendicular to the surface to obtain an initial model formed after the surface is extended.

[0032] Specifically, the surface of the concrete model is identified by BIM software or other modeling tools. Then, the target distance is extended into the concrete model based on the direction perpendicular to the surface. The normal direction of the extension direction can be automatically determined by geometric calculation or software tools.

[0033] For example, in this embodiment, the model of the bridge may not only be provided with planes, but also include various curved surfaces. Therefore, in this embodiment, all surfaces of the concrete model may be obtained, and all surfaces may be classified according to surface types to form curved surface groups and plane groups. Then, When the surface belongs to the plane group, extend the surface in a direction perpendicular to the surface by a target distance L1; When the surface belongs to a surface group, the surface is subdivided using the surface subdivision function of the BIM software to form multiple independent sub-planes based on each surface, and the target distance L1 is extended in a direction perpendicular to the sub-plane based on each sub-plane.

[0034] It can be understood that through the above steps, an initial model can be obtained that is parallel to the surface of the original concrete model but offset inward by a certain distance. The above method avoids the influence of temperature gradient changes between the concrete and the internal temperature during solidification due to external interference from environmental factors during the solidification process.

[0035] Of course, some concrete components may be small in size and completely cover the original concrete model after the offset. Therefore, in this embodiment, if the extended path interferes with any other surface of the concrete model after the surface is extended, the extension is stopped when the extended path intersects with the surface of the concrete model.

[0036] After the secondary extension, multiple sub-models formed by extending the surfaces of multiple concrete models can be obtained, and the multiple sub-models can be combined to obtain an initial model.

[0037] For the merging process, the model merging function in the BIM software can be used. For example, multiple sub-models are selected and merged using the model merging function in the BIM software. The original spatial position of each sub-model is retained during the merging process. When any two or more sub-models overlap, the overlapping model content of any sub-model is retained and the overlapping parts of the model content of the remaining sub-models are removed.

[0038] S103: Acquire an initial model, determine multiple target points based on the initial model, and determine the core temperature point based on the multiple target points.

[0039] Specifically, in the present embodiment, the target point position is the position closest to the core, but due to the influence of the measurement method, the core temperature cannot be measured directly. Therefore, in order to be able to measure the point closest to the core temperature, in the present embodiment, an initial model can be obtained, and multiple target surfaces on the initial model can be determined. Then, based on the positional relationship between the multiple target surfaces, multiple target points are determined, wherein the multiple target points are the intersection points of three or more intersecting target surfaces on the initial model.

[0040] It can be understood that the intersection of the vertex angle facing outward will not be close to the actual temperature value in this embodiment. Therefore, for the type of vertex angle, all target points can be obtained, and based on the target point type, multiple core temperature points are identified from multiple target points, where the core temperature point is the intersection of three or more target surfaces, and when three or more target surfaces intersect, the vertex angle formed is directed toward the inside of the initial model.

[0041] It will be appreciated that these intersection points may be the points in the model that are closest to the true internal temperature.

[0042] S104: Determine multiple target points based on each core temperature point, wherein the distance between the multiple target points corresponding to one core temperature point and the core temperature point is L2, and L2 is greater than L1.

[0043] Specifically, in this embodiment, after the points are determined, since the points are on the virtual initial model, when these points are actually measured, these points are inside the concrete model, and the measurement may cause damage to the concrete structure. Therefore, in this embodiment, the internal temperature can be calculated by measuring the surface temperature in combination with the test data when the temperature of the concrete diffuses in a spherical shape during solidification. The thermal diffusion data of concrete during solidification has been disclosed in relevant technical documents and will not be repeated in this application.

[0044] For example, each core temperature point can be taken as the sphere center to obtain a reference sphere corresponding to each core temperature point, and the radius of the sphere is L2. It can be understood that in order to ensure that the point does not exist inside the concrete when the point is selected later, the radius of the sphere L2 must be greater than the distance L1 when the surface offset is performed originally.

[0045] One or more target points are determined from the surface of each reference sphere, and the target points are one or more points on the surface of the sphere that are farthest from the surface of the concrete model.

[0046] It can be understood that for each reference sphere formed by the points, the points on its surface can be traversed, and of course, a series of points can be generated by discretizing the sphere surface, and the specific method is not limited. These points are at the same distance from the core temperature point, so they meet the concrete thermal diffusion data type.

[0047] S105: Acquire a projection point of each target point on the surface of the concrete model, wherein a vertical line from the projection point to the surface passes through the target point.

[0048] As you can understand, for each target point, find the point on the concrete model surface that is closest to that point, that is, the projection point. Make sure that the vertical line from the projection point to the concrete model surface passes through the target point. Of course, if the concrete model surface is a complex curved surface, you can use numerical methods (such as iterative closest point algorithm) or built-in functions of BIM software to accurately calculate the projection point. Of course, you can also use the closest point search algorithm (such as KD tree or spatial index) to quickly find the point on the concrete model surface that is closest to the target point.

[0049] S106: Acquire the concrete surface temperature of multiple projection points, and determine the average temperature of the concrete model based on the surface temperature.

[0050] It can be understood that after the target point is determined, the temperature of the core point can be obtained by directly measuring the temperature of the target point and combining it with the concrete temperature diffusion formula, thereby further improving the accuracy of concrete temperature monitoring.

[0051] The embodiment of the present application proposes a BIM-based temperature monitoring method for a bridge mass concrete. First, the surface of the concrete model is determined. Based on the surface, a target distance L1 is extended into the concrete model, and the direction of extension is perpendicular to the surface. The initial model formed after the surface extension is obtained, and then the initial model is obtained. Multiple target points are determined based on the initial model. The core temperature point is determined based on the multiple target points. Then, multiple target points are determined based on each core temperature point, wherein multiple target points corresponding to one core temperature point, and then the projection point of each target point on the surface of the concrete model is obtained, wherein the vertical line from the projection point to the surface passes through the target point, and then the concrete surface temperature of the multiple projection points is obtained, and the average temperature of the concrete model is determined based on the surface temperature. The present application proposes a BIM-based temperature monitoring method for a bridge mass concrete. The bridge model is obtained through BIM, and the model is translated along the surface to determine multiple concrete core points that are not affected by the external environment. The model is combined with the heat diffusion data during the solidification of the concrete to determine multiple points that can be directly measured from the concrete model, and the average temperature of the concrete model is calculated after measurement. It is fast and convenient and will not cause damage to the concrete model.
