Description

Technical Field

[0001] The invention relates to the technical field of construction progress detection, in particular to a construction progress detection system for large-scale assembly components based on BIM technology. Background Art

[0002] When building bridges, roads and bridges, and large-scale building complexes, it is usually difficult to accurately control the construction progress. However, accurate control of the construction progress helps to reasonably dispatch the means of production. The current traditional practice is to divide the entire large assembly into several sections, and to carry out construction in steps through several sections to ensure the construction progress. However, in the construction process of large assemblies, the foundation part of the large assembly is required to be constructed continuously to ensure that the overall quality is not unbalanced due to misaligned construction. Especially when pouring concrete, if the same foundation part is poured in multiple sections, it will result in joints and cannot be integrated. Summary of the invention

[0003] The purpose of the present invention is to provide a method for detecting the deflection of an assembled building based on BIM technology to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A construction progress detection system for large-scale assembly components based on BIM technology includes: a basic data acquisition module, which installs a number of spatially evenly arranged positioning tags on the installation base of the constructed large-scale assembly component, determines the measured geographical location data of each positioning tag, and performs 3D scanning on the base through a scanning device to obtain 3D scanning data of the base;

[0006] The model building module builds a three-dimensional model of the base in the BIM software based on the obtained 3D scanning data of the base, sets the basic coordinate system of the three-dimensional model of the base, calibrates the measured geographical location data in the basic coordinate system according to the measured geographical location data of the positioning tags, and determines the overall three-dimensional measured geographical location data and actual coordinate system of the three-dimensional model of the base through the measured geographical location data of the positioning tags;

[0007] A large assembly component construction module constructs an assembly component model of the large assembly component based on the construction process and design drawings of the large assembly component, and calibrates the installation position of the assembly component model with the actual coordinate system of the base three-dimensional model to form a calibration coordinate;

[0008] The lap module is used to lap the assembly component model onto the base three-dimensional model using the calibrated coordinates, and the lap module has:

[0009] Structured segmentation unit;

[0010] A structural arrangement unit, wherein the structural arrangement unit is configured to divide the base three-dimensional model and the assembly component model overlapped on the base three-dimensional model into a plurality of space units with consistent upper and lower spatial structures and uniform arrangement according to the structural segmentation unit determined in the construction progress, and the space unit has at least one set positioning label;

[0012] An output unit, outputting the set of marker points and the spatial coordinates corresponding to the set of marker points;

[0013] An assembly control module, the assembly control module comprising:

[0014] The assembly progress output terminal is used to output the positioning tag, the tag coordinates corresponding to the positioning tag, the marker point set, and the space coordinates corresponding to the marker point set according to the delineated space block, and use them at the on-site control terminal; the on-site control terminal performs actual construction progress measurement based on the obtained tag coordinates, the marker point set, and the space coordinates corresponding to the marker point set to obtain the progress measurement value of the construction progress;

[0015] An assembly progress input terminal is used to determine the spatial extension progress of the base and the large assembly components arranged on the base according to the progress measurement value obtained from the actual construction progress on site; and the extension progress is represented by a spatial block and a set of marking points corresponding to the spatial block and the spatial coordinates corresponding to the set of marking points;

[0016] The verification unit is used to determine whether the construction progress meets the standard based on the progress measurement values ​​of the spatial extension progress of the large assembly components and the construction progress.

[0017] Furthermore, the positioning label uses the upper surface of the base as a layout reference plane, and arranges a number of evenly arranged positioning labels in sequence along the side of the upper surface toward the middle part of the upper surface to form a middle space plane. Taking the middle space plane as a reference, at least one lower space plane and upper space plane are arranged below and above the middle space plane respectively, and the positioning labels arranged on the middle space plane, the lower space plane and the upper space plane correspond to each other in spatial position.

[0018] Furthermore, the measured geographical location data of the positioning tag set on the base is obtained.

[0019] Furthermore, when the base is 3D scanned, the positioning tags are also scanned in sequence, and the scanning result of the base is verified by the positioning tags;

[0020] During verification, the result of the base scanning is verified by the corresponding arrangement positions of the positioning tags on the middle space plane, the lower space plane and the upper space plane and the distances between adjacent positioning tags.

[0021] Furthermore, according to the construction process of the large assembly component, the large assembly component is divided into a number of basic components by construction elements, and the spatial position corresponding to each basic component is auxiliary marked by positioning tags.

[0022] Furthermore, when constructing an assembly component model of a large assembly component, a basic component model of each basic component is constructed separately according to a number of basic components constituting the large assembly component, and when the basic component model is constructed, the positioning tag and the measured geographical location data corresponding to the positioning tag are used as a benchmark reference when constructing the basic component model.

[0023] Furthermore, the structural segmentation unit uses the set construction period of each basic component as a standard for structural division.

[0024] Furthermore, when dividing the space units, each space unit includes at least one complete basic component.

[0025] Furthermore, the outer contour of the basic component is used as a marker point set to select points, and the marker point set fully covers the outer contour of the basic component.

[0026] Furthermore, the on-site control terminal is provided with an assembly component model and a three-dimensional model of the base in a backup manner, and the positioning tag, the tag coordinates corresponding to the positioning tag, the marker point set and the spatial coordinates corresponding to the marker point set are input to the on-site control terminal according to the designated spatial blocks and form a corresponding spatial match with the assembly component model and the three-dimensional model of the base.

[0027] This application can realize the marking of on-site construction progress through the on-site control terminal, and through communication with the on-site control terminal, the marking results can be fed back in real time, so that the real-time construction progress can be understood, which is conducive to the scheduling of production materials.

[0028] This application uses the basic components as the segmentation standard for large assemblies. When the basic components are used as the segmentation standard, it can be ensured that the basic components will not have the wrong direction of segmentation construction in a continuous construction cycle, ensuring the overall construction quality. The entire basic component will not have joint problems caused by segmentation construction.

[0029] This application constructs positioning tags and uses the measured geographic location data of the positioning tags as coordinate data when building the model. In this way, the construction progress on site is actually synchronized with the data under the same coordinate system, ensuring that the overall construction progress can be accurately controlled.

[0030] Figure 1 It is a schematic diagram of the system framework principle of the present invention. DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 The present invention discloses a construction progress detection system for large-scale assembly components based on BIM technology, including: a basic data acquisition module, which installs a number of spatially evenly arranged positioning tags on the installation base of the constructed large-scale assembly component, determines the measured geographical location data of each positioning tag, and performs 3D scanning on the base through a scanning device to obtain 3D scanning data of the base;

[0033] The model building module builds a three-dimensional model of the base in the BIM software based on the obtained 3D scanning data of the base, sets the basic coordinate system of the three-dimensional model of the base, calibrates the measured geographical location data in the basic coordinate system according to the measured geographical location data of the positioning tags, and determines the overall three-dimensional measured geographical location data and actual coordinate system of the three-dimensional model of the base through the measured geographical location data of the positioning tags;

[0034] A large assembly component construction module constructs an assembly component model of the large assembly component based on the construction process and design drawings of the large assembly component, and calibrates the installation position of the assembly component model with the actual coordinate system of the base three-dimensional model to form a calibration coordinate;

[0035] The lap module is used to lap the assembly component model onto the base three-dimensional model using the calibrated coordinates, and the lap module has:

[0036] Structured segmentation unit;

[0037] A structural arrangement unit, wherein the structural arrangement unit is configured to divide the base three-dimensional model and the assembly component model overlapped on the base three-dimensional model into a plurality of space units with consistent upper and lower spatial structures and uniform arrangement according to the structural segmentation unit determined in the construction progress, and the space unit has at least one set positioning label;

[0038] A docking detection unit, taking the tag coordinates of the positioning tag as a reference, constructing a plurality of marker point sets in the space unit according to a set rule, dividing the space unit into a plurality of space blocks by the marker point sets, and determining the docking points of the space blocks by the marker point sets;

[0039] An output unit, outputting the set of marker points and the spatial coordinates corresponding to the set of marker points;

[0040] An assembly control module, the assembly control module comprising:

[0041] The assembly progress output terminal is used to output the positioning tag, the tag coordinates corresponding to the positioning tag, the marker point set, and the space coordinates corresponding to the marker point set according to the delineated space block, and use them at the on-site control terminal; the on-site control terminal performs actual construction progress measurement based on the obtained tag coordinates, the marker point set, and the space coordinates corresponding to the marker point set to obtain the progress measurement value of the construction progress;

[0042] An assembly progress input terminal is used to determine the spatial extension progress of the base and the large assembly components arranged on the base according to the progress measurement value obtained from the actual construction progress on site; and the extension progress is represented by a spatial block and a set of marking points corresponding to the spatial block and the spatial coordinates corresponding to the set of marking points;

[0043] The verification unit is used to determine whether the construction progress meets the standard based on the progress measurement values ​​of the spatial extension progress of the large assembly components and the construction progress.

[0044] In some embodiments, the positioning labels use the upper surface of the base as a layout reference plane, and a number of evenly arranged positioning labels are arranged in sequence along the sides of the upper surface toward the middle of the upper surface to form a middle space plane. With the middle space plane as a reference, at least one lower space plane and upper space plane are arranged below and above the middle space plane, respectively, and the positioning labels arranged on the middle space plane, the lower space plane and the upper space plane correspond to each other in spatial position.

[0045] In some embodiments, the measured geographic location data of the positioning tag is obtained through the positioning tag set on the base.

[0046] In some embodiments, when the base is 3D scanned, the positioning tag is also scanned in sequence, and the scanning result of the base is verified by the positioning tag;

[0047] During verification, the result of the base scanning is verified by the corresponding arrangement positions of the positioning tags on the middle space plane, the lower space plane and the upper space plane and the distances between adjacent positioning tags.

[0048] In some embodiments, verifying the result of the base scanning by the corresponding layout positions of the positioning tags on the middle space plane, the lower space plane and the upper space plane and the distances between adjacent positioning tags includes:

[0049] The corresponding layout positions of the positioning labels on the middle space plane, the lower space plane and the upper space plane are numbered in sequence, and the positions on the same space plane have the same numbering rule;

[0050] Measuring a first distance between any two adjacent positioning tags on the same spatial plane, marking and recording the first distance, and then measuring a second distance between any two adjacent positioning tags on different spatial planes, marking and recording the second distance;

[0051] Perform 3D scanning on the base and the positioning tag, and import the obtained 3D scanning data into the BIM software to construct the 3D outline of the base 3D model. During the construction process, firstly construct a basic coordinate system in the BIM software, mark the position of the positioning tag in the 3D model of the base in the basic coordinate system in sequence, and obtain the reference coordinate data corresponding to the positioning tag;

[0052] Acquire the measured geographic location data of the positioning tag, import the measured geographic location data of the positioning tag into the basic coordinate system, and perform coordinate data transformation through the measured geographic location data of each positioning tag and the reference coordinate data to form an actual coordinate system based on the measured geographic location data;

[0053] Deriving a third distance between any two positioning tags in the same spatial plane and a fourth distance between any two positioning tags in different spatial planes in the actual coordinate system;

[0054] By comparing the first distance, the second distance, the third distance and the fourth distance corresponding to any two of the positioning tags, the result of the base scanning is verified;

[0055] If the verification results are consistent, the constructed 3D model of the base and the actual coordinate system of the 3D model of the base obtained by the overall 3D measured geographic location data are saved;

[0056] If the verification results are inconsistent, the corresponding third distance and fourth distance are corrected using the first distance and the second distance.

[0057] In some embodiments, according to the construction process of the large assembly component, the large assembly component is divided into a number of basic components by construction elements, and the spatial position corresponding to each basic component is auxiliary marked by positioning tags.

[0058] In some embodiments, the basic component refers to any part of the large assembly component that needs to be constructed continuously to ensure the construction quality requirements when the construction process is used as a reference. Therefore, when the basic component is divided by the structural division unit in the later stage, it must be ensured that the basic component is a small whole, and the basic component is configured to be continuously constructed within a complete construction cycle;

[0059] It is understandable that the large assembly component is divided into several basic components, and each basic component is regarded as a whole. When constructing the construction process, artificial experts first mark the several basic components that constitute the large assembly component one by one, and make each basic component a complete whole. In this way, continuous construction is required during construction to ensure the quality of construction. It is also necessary to explain that when any two or more basic components have assembly adaptation, it is necessary to coordinate the configuration of the two or more basic components according to the construction process requirements. The coordinated configuration can be the simultaneous construction of two or more basic components, or it can be staggered construction. The specific method to be used is determined according to the adaptation relationship between the basic components at the construction site.

[0060] In some embodiments, when positioning tags are arranged, the position of the base component in the entire large assembly component should also be considered to ensure that there is at least one positioning tag in the middle spatial plane, the lower spatial plane and the upper spatial plane within a base component.

[0061] In some embodiments, when constructing an assembly component model of a large assembly component, a basic component model of each basic component is constructed separately according to several basic components constituting the large assembly component, and when the basic component model is constructed, the positioning tag and the measured geographical location data corresponding to the positioning tag are used as a benchmark reference when constructing the basic component model.

[0062] In some embodiments, the structural segmentation unit uses the set construction period of each basic component as a standard for structural division.

[0063] In some embodiments, when dividing the space units, each space unit includes at least one complete basic component.

[0064] In some embodiments, the outer contour of the basic component is used as a marker point set to select points, and the marker point set is made to fully cover the outer contour of the basic component;

[0065] It should be understood that the set of marking points is actually composed of a number of marking points selected along the outer contour of the basic component, and when these marking points are connected by smooth curves, the outer contour of the basic component is exactly displayed;

[0066] In this way, when a space unit contains multiple basic components, this space unit actually contains multiple basic components. Therefore, when the space unit is divided into several space blocks, the basic construction model is also used as the division standard.

[0067] It should also be pointed out that since the present application uses marking points selected along the outer contour of the basic component, any two of the interconnected basic components have some overlapping marking points, and any two connected basic components can also be connected through these overlapping marking points.

[0068] In some embodiments, the field control terminal is provided with the assembly component model and the base three-dimensional model in a backup manner, and the positioning tag, the tag coordinates corresponding to the positioning tag, the marker point set, and the space coordinates corresponding to the marker point set are input to the field control terminal according to the delineated space blocks and form a corresponding space match with the assembly component model and the base three-dimensional model;

[0069] At the on-site control end, the positioning tags contained in the model are led out in sequence according to the construction process sequence, and an lead-out path for the positioning tags is constructed at the same time. The lead-out path uses the tag coordinates corresponding to the positioning tag as a recognizable prefix segment, and the lead-out path is configured so that when any positioning tag arranged on site is reached according to the on-site construction progress, the corresponding measured geographic location data of the positioning tag arranged on site is used to query the corresponding matching lead-out path at the on-site control end. The corresponding marking can be made on the assembly component model by making corresponding markings on the lead-out path. Specifically, the construction of any spatial block can be marked by the positioning tag corresponding to the lead-out path, so that the on-site control end can update the construction progress in real time.

[0070] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
