Description

Technical Field

[0001] The present invention relates to the technical field of construction site inspection management, and specifically to a construction site inspection management system and method based on BIM twin. Background Art

[0002] With the rapid development of BIM technology, the application of BIM models in construction management has become increasingly widespread and has gradually become an important tool for the whole life cycle management of construction engineering projects. The application of BIM technology in construction can effectively improve construction efficiency and quality, reduce construction costs, and reduce safety accidents, which is of great significance for the smooth implementation of construction engineering projects.

[0003] During the construction process of buildings, the management and inspection of construction sites are important links to ensure project quality and progress. The traditional construction site inspection method mainly relies on on-site manual inspection, which has problems such as low efficiency, high cost, and difficulty in real-time monitoring. At the same time, it is difficult to detect minor construction deviations existing in the construction site through manual on-site inspection, and the traditional construction site inspection method cannot achieve global inspection. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction site inspection management system and method based on BIM twin to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A construction site inspection management method based on BIM twin, the method includes:

[0006] S10: According to the construction three-dimensional drawings of the construction site, construct a BIM three-dimensional model of the building to be constructed. Based on a number of panoramic cameras arranged at the construction site, collect real-time panoramic images of each construction area at the construction site, and integrate the collected real-time panoramic images of each construction area to obtain a real-time panoramic image of the construction site. Compare the real-time panoramic image of the construction site with the BIM three-dimensional model in a 1:1 ratio, and generate a comparison result;

[0007] S20: According to the real-time abnormality degree of each construction area and the positional relationship between each marked construction building part, predict the real-time influence coefficient of each construction area on the adjacent construction areas, and generate a real-time remote inspection report of the construction site;

[0008] S30: Generate a real-time inspection plan for the construction site according to the real-time remote inspection report of the construction site;

[0009] S40: Conduct inspection control on the construction site according to the real-time remote inspection plan of the construction site.

[0010] Further, the S10 includes:

[0011] S101: Regarding each enclosed area existing in each building floor of the building to be constructed as a construction sub - area, number each building floor of the building to be constructed in the order from bottom to top in the BIM three - dimensional model. The numbering result is: i = 1, 2, …, m; m represents the total number of building floors. Number each construction sub - area existing in each building floor. The numbering result is: j = 1, 2, …, n; n represents the total number of numbers.

[0012] S102: Through a number of panoramic cameras arranged at the construction site, collect the real - time panoramic images of the j - th construction sub - area in the i - th building floor, and integrate the collected real - time panoramic images of each construction sub - area according to the spatial position relationship between each construction sub - area to obtain the real - time panoramic image of the construction site.

[0013] S103: Make a 1:1 comparison between the real - time panoramic image of the construction site and the BIM three - dimensional model, mark the parts of the construction building that do not coincide in the comparison in the BIM three - dimensional model, randomly select a point in the BIM three - dimensional model as the coordinate origin to construct a three - dimensional space coordinate system, and obtain the marked vertex coordinates in the three - dimensional space coordinate system. The marked vertex coordinates refer to the vertex coordinates of the three - dimensional polygon corresponding to each marked construction building part in the BIM three - dimensional model.

[0014] The generated comparison result is: the set M of the obtained marked vertex coordinates, M = {(x1, y1) ij , …, (x p , y p ) ij}, where p = 1, 2, …, q, representing the numbers corresponding to each marked vertex coordinate existing in each construction sub - area, q represents the total number of marked vertex coordinates existing in each construction sub - area, and (x p , y p ) ij} represents the marked vertex coordinate numbered p in the j - th construction sub - area of the i - th building floor. By making a 1:1 comparison between the constructed BIM three - dimensional model and the real - time panoramic image of the construction site, it is possible to quickly determine whether there is abnormal construction at the construction site.

[0015] Further, the S20 includes:

[0016] S201: In the BIM three - dimensional model, number each marked construction building part at time t. The numbering result is: c t = 1 t , 2 t , …, C t , C tDenote the total number of marked construction building parts in the BIM 3D model at time t, and judge the marked number as c t Whether the shortest distance between the three-dimensional polygon corresponding to the construction building part with the marked number c t and the three-dimensional polygon corresponding to the construction building part with the marked number v t is 0. If it is 0, it means that the construction building part with the marked number c t is adjacent to the construction building part with the marked number v t At this time, calculate the overlapping area t between the construction building part with the marked number c and the construction building part with the marked number v t If it is not 0, it means that the construction building part with the marked number c t is not adjacent to the construction building part with the marked number v Among them, v t = 1 t , 2 t , …, C t And v t ≠ c t , and t represents the real-time time value;

[0017] S202: Obtain the volume t of the three-dimensional polygon corresponding to the construction building part with the marked number c At time t, take the ratio of the sum V ijt of the volumes of the three-dimensional polygons corresponding to the marked construction building parts existing in the jth construction sub-region of the ith building layer to the enclosed volume H ij of the jth construction sub-region of the ith building layer as the abnormality degree value F ijt of the jth construction sub-region of the ith building layer at time t;

[0018] S203: Re-mark the marked construction building parts existing in the jth construction sub-region of the ith building layer. At time t, obtain the re-marked construction building parts with adjacent marked construction building parts, calculate the overlapping area between each obtained re-marked construction building part and the marked construction building part adjacent to each obtained re-marked construction building part, and perform a summation process on the calculated overlapping areas. Denote the summation result as S ijt , and take [1 - exp(-S ijt )]*F ijt as the influence coefficient of the jth construction sub-region of the ith building layer on the construction sub-region adjacent to the jth construction sub-region of the ith building layer at time t, where exp represents the exponential function with the real number e as the base and e = 2.72;

[0019] S204: When 0 < F ijt ≤ 1, the abnormality degree value F of the j-th construction sub-zone at the i-th building layer at time t, ijt and the influence coefficient of the j-th construction sub-zone at the i-th building layer at time t on the construction sub-zones adjacent to the j-th construction sub-zone at the i-th building layer [1 - exp(-S ijt )]*F ijt are recorded in the patrol inspection report template at the construction site; otherwise, they are not recorded in the patrol inspection report template at the construction site;

[0020] Generate a remote patrol inspection report for the construction site at time t according to the recording result.

[0021] Furthermore, the specific method for S30 to generate a real-time patrol inspection plan for the construction site is as follows:

[0022] S301: Search for the maximum value of [1 - exp(-S ijt )]*F ijt , where g = 1, 2,..., m and g ≠ i, h = 1, 2,..., n and h ≠ j; ght *F ght

[0023] S302: When F ijt = 0, no patrol inspection plan is generated for the construction site at time t;

[0024] S303: When [1 - exp(-S ght )]*F ght = 0 and F ijt ≠ 0, sort (X ijt , Y ij ) in descending order of F ij and the principle of the shortest distance to obtain the sorting sequence K. The F ijt values participating in the sorting process are not 0, and (X ij , Y ij ) represents the central coordinates of the j-th construction sub-zone at the i-th building layer. Generate a patrol inspection plan K t for the construction site at time t according to the sorting sequence K. The patrol inspection order of the patrol inspection plan K t is: the construction sub-zone corresponding to the first item of the sorting sequence K → the construction sub-zone corresponding to the second item of the sorting sequence K →... → the construction sub-zone corresponding to the last item of the sorting sequence K;

[0025] S304: When [1 - exp(-S ght )]*F ght ≠ 0, if [1 - exp(-S ijt )]*F ijt ​

[0026] ≠0, then put [1 - exp(-S ijt )]*F ijt corresponding central coordinate (X ij , Y ij ) into set T. If [1 - exp(-S ijt )]*F ijt = 0, then do not put [1 - exp(-S ijt )]*F ijt corresponding central coordinate (X ij , Y ij ) into set T. Randomly select a central coordinate in set T, and denote the selected central coordinate as (X rd , Y rd ), where r = 1, 2, …, m and r ≠ i, d = 1, 2, …, n and d ≠ j;

[0027] Randomly select another central coordinate in set T, and denote the selected other central coordinate as (X gh , Y gh ). Calculate the difference L rd between Y gh and Y rd→gh . If L rd→gh > 0, then let L rd→gh = 0. If L rd→gh ≤0, then let L rd→gh = b rd→gh , b rd→gh = 0 or b rd→gh = 1. When b rd→gh = 1, it means that the shortest distance value between the d-th construction sub - area in the r - th building layer and the h - th construction sub - area in the g - th building layer calculated according to the distance formula between two coordinates is 0. When b rd→gh = 0, it means that the shortest distance value between the d-th construction sub - area in the r - th building layer and the h - th construction sub - area in the g - th building layer calculated according to the distance formula between two coordinates is not 0. Until all other central coordinates stored in set T are selected, perform a summation process on L rd→gh , and denote the summation result as I rd . Take the ratio between I rd and the quantity value of the construction sub - areas existing in the building to be constructed as the inspection index of the d-th construction sub - area in the r - th building layer; Analyze the negative impact of each construction sub - area on other construction sub - areas according to the deviation of the central coordinates corresponding to the construction sub - areas in the vertical direction, which is beneficial to quickly lock the construction sub - area with the most serious construction anomaly problem;

[0028] S305: Repeat the operation method of S304 until all the central coordinates in set T are selected. Calculate the inspection indices of the construction zones corresponding to each central coordinate stored in set T, and sort the central coordinates stored in set T according to the descending order of the inspection indices and the principle of proximity by distance, obtaining a sorted sequence J. Generate an inspection plan J for the construction site at time t according to the sorted sequence J. t , the inspection plan J t has the following inspection order: the construction zone corresponding to the first item of the sorted sequence J → the construction zone corresponding to the second item of the sorted sequence J →... → the construction zone corresponding to the last item of the sorted sequence J. Analyze the construction zones that require manual inspection by the inspection personnel according to the real-time anomaly degree values of each construction zone and the influence coefficients of each construction zone on adjacent construction zones. The inspection personnel selectively inspect the construction zones, reducing the work intensity of the inspection personnel.

[0029] Further, the S40 includes:

[0030] When F ijt = 0, all the construction zones under the control of the construction site are in the working state;

[0031] When [1 - exp(-S ght )] * F ght = 0 and F ijt ≠ 0, the construction zones that need to be inspected in the inspection plan are in the suspended state, and the construction zones that do not need to be inspected in the inspection plan are in the working state. The inspection personnel inspect the construction site according to the inspection plan K t ;

[0032] When [1 - exp(-S ght )] * F ght ≠ 0, all the construction zones under the control of the construction site are in the suspended state. The inspection personnel inspect the construction site according to the inspection plan J t . The construction team rectifies the construction zones inspected by the inspection personnel according to the rectification measures proposed by the inspection personnel. The rectification order of the construction zones inspected by the inspection personnel by the construction team is according to the inspection order of the inspection plan J t . Until there is no misaligned construction building part in the BIM three-dimensional model, the rectification of the construction zones inspected by the inspection personnel by the construction team ends. Determining the best inspection order of the inspection personnel and the rectification order of the construction zones by the construction team is conducive to ensuring that the construction team completes the rectification task in a short time, thereby guaranteeing the construction progress of the building to be constructed.

[0033] A construction site inspection management system based on BIM twin, the system includes a calibration module, a remote inspection report generation module, an inspection plan generation module, and an inspection control module;

[0034] The calibration module is used to calibrate the real-time panoramic image of the construction site with the BIM three-dimensional model on a 1:1 basis and generate a comparison result;

[0035] The remote inspection report generation module is used to predict the real-time influence coefficient of each construction area on the adjacent construction areas according to the real-time abnormal degree of each construction area and the positional relationship between the marked construction building parts, and generate a real-time remote inspection report of the construction site;

[0036] The inspection plan generation module is used to generate a real-time inspection plan for the construction site;

[0037] The inspection control module is used to conduct inspection control on the construction site.

[0038] Further, the calibration module includes a construction area determination unit, a panoramic image acquisition unit, and a comparison result generation unit;

[0039] The construction area determination unit takes each enclosed area existing in each building layer of the building to be constructed as a construction area;

[0040] The panoramic image acquisition unit collects the real-time panoramic images of each area through a number of panoramic cameras arranged at the construction site, and integrates the collected real-time panoramic images of each construction area according to the spatial positional relationship between the construction areas to obtain the real-time panoramic image of the construction site;

[0041] The comparison result generation unit calibrates the real-time panoramic image of the construction site with the BIM three-dimensional model on a 1:1 basis, marks the construction building parts that do not coincide in the calibration in the BIM three-dimensional model, randomly selects a point in the BIM three-dimensional model as the coordinate origin to construct a three-dimensional space coordinate system, and obtains the marked vertex coordinates in the three-dimensional space coordinate system, and generates a comparison result based on the obtained marked vertex coordinates.

[0042] Further, the remote inspection report generation module includes an overlapping area calculation unit, an abnormal degree value calculation unit, an influence coefficient calculation unit, and a remote inspection report generation unit;

[0043] The overlapping area calculation unit judges whether two randomly selected marked construction building parts are adjacent according to the shortest distance value between the corresponding three-dimensional polygon figures of the two randomly marked construction building parts, and calculates the overlapping area between the two randomly selected marked construction building parts according to the judgment result;

[0044] The abnormal degree value calculation unit calculates the real-time abnormal degree value of the construction area according to the sum of the volumes of the three-dimensional polygon graphics corresponding to each marked construction building part existing in real time in the construction area and the enclosed volume of the construction area;

[0045] The influence coefficient calculation unit uses the overlapping area calculation unit to calculate the overlapping area between each re-marked construction building part obtained in real time and the marked construction building part adjacent to the obtained re-marked construction building part, and combines the real-time abnormal degree value of the construction area calculated by the abnormal degree value calculation unit to calculate the influence coefficient of the construction area on the adjacent construction area;

[0046] The remote inspection report generation unit selectively records the content to be recorded in the on-site inspection report template according to the real-time abnormal degree value of the construction area calculated by the abnormal degree value calculation unit.

[0047] Furthermore, the inspection plan generation unit includes a judgment unit, a first inspection plan generation unit, an inspection index prediction unit, and a second inspection plan generation unit;

[0048] The judgment unit judges whether it is necessary to generate a real-time inspection plan for the construction site according to the relationship between the real-time abnormal degree value of the construction area calculated by the abnormal degree value calculation unit and the value 0;

[0049] When the real-time abnormal degree value of the construction area calculated by the abnormal degree value calculation unit ≠ 0 and the maximum image coefficient value calculated by the influence coefficient calculation unit = 0, the first inspection plan generation unit sorts the central coordinates of each construction area in descending order of the real-time abnormal degree value of each construction area and the principle of the nearest distance, and based on the sorting process, generates a real-time inspection plan for the construction site;

[0050] When the maximum image coefficient value calculated by the influence coefficient calculation unit ≠ 0 and the image coefficient ≠ 0, the inspection index prediction unit puts the central coordinates of the construction area corresponding to the influence coefficient into the set, and predicts the inspection index of each construction area according to the deviation of any two central coordinates in the set on the Y-axis;

[0051] When the maximum image coefficient value calculated by the influence coefficient calculation unit ≠ 0, the second inspection plan generation unit sorts the central coordinates stored in the set in descending order of the inspection index and the principle of the nearest distance, and based on the sorting process, generates a real-time inspection plan for the construction site.

[0052] Furthermore, the inspection control module includes a first inspection control unit, a second inspection control unit, and a third inspection control unit;

[0053] When the real-time abnormality degree value of the construction sub-area calculated by the abnormality degree value calculation unit of the first patrol control unit ≠ 0, all construction sub-areas for controlling the construction site are in a working state;

[0054] When the real-time abnormality degree value of the construction sub-area calculated by the abnormality degree value calculation unit of the second patrol control unit ≠ 0 and the maximum image coefficient value calculated by the influence coefficient calculation unit = 0, the construction sub-areas that need to be patrolled in the patrol plan are in a shutdown state, and the construction sub-areas that do not need to be patrolled in the patrol plan are in a working state. The patrol personnel conduct patrols on the construction site according to the patrol plan generated by the first patrol plan generation unit;

[0055] When the maximum image coefficient value calculated by the influence coefficient calculation unit of the third patrol control unit ≠ 0, all construction sub-areas for controlling the construction site are in a shutdown state. The patrol personnel conduct patrols on the construction site according to Patrol Plan J t The construction team conducts rectification and treatment on the construction sub-areas patrolled by the patrol personnel according to the rectification measures proposed by the patrol personnel until there are no non-coincident construction building parts in the BIM three-dimensional model. Then, the rectification of the construction sub-areas patrolled by the patrol personnel by the construction team ends.

[0056] Compared with the prior art, the beneficial effects of the present invention are:

[0057] 1. By comparing the constructed BIM three-dimensional model with the real-time panoramic image of the construction site on a 1:1 basis, the present invention can quickly determine whether there is abnormal construction at the construction site. This process does not require manual participation, saving manpower and material resources while accurately identifying minor construction deviations at the construction site. At the same time, real-time monitoring of the construction site is achieved.

[0058] 2. The present invention predicts the real-time patrol index of each construction sub-area based on the real-time abnormality degree value of each construction sub-area and the influence coefficient of each construction sub-area on adjacent construction sub-areas. Based on the prediction results, the construction sub-areas that require manual patrol by patrol personnel are analyzed. The patrol personnel selectively patrol the construction sub-areas, improving the patrol control efficiency of the patrol personnel on the construction site, and determining the optimal patrol order of the patrol personnel and the rectification order of the construction team for the construction sub-areas, which is beneficial to ensuring that the construction team completes the rectification task in a short time and thus guaranteeing the construction progress of the building to be constructed.

[0059] 3. The present invention analyzes the negative impact of each construction sub - area on other construction sub - areas through the deviation of the central coordinates corresponding to each construction sub - area in the longitudinal direction, which is conducive to quickly locking the construction sub - area with the most construction anomalies, ensuring that the inspection personnel can comprehensively and detailedly understand the construction problems existing at the construction site according to the inspection plan, and then ensuring that the inspection personnel can give the most appropriate rectification measures in a short time, further improving the inspection and control effect of the system on the construction site.

Judge the marked number c tThe three-dimensional polygonal figure corresponding to the construction part of the building is marked with v t Is the shortest distance between the three-dimensional polygonal figures corresponding to the construction part of the building 0? If it is 0, it means that the mark number is c t The construction building part is marked with number v t The construction part is adjacent to the building numbered c. t The construction part or marking number is v t There is an adjacent marked construction part in the construction part of the building. In this case, the mark number is c. t The construction building part is marked with number v t Overlap area between construction building parts Calculate, if it is not 0, it means the tag number is c t The construction building part is marked with number v t The construction parts are not adjacent.

[0074] S203: Re-mark the marked construction building parts existing in the j-th construction partition in the building layer numbered i, and at time t, obtain the re-marked construction building parts with adjacent marked construction building parts, calculate the overlapping areas between each obtained re-marked construction building part and the marked construction building parts adjacent to each obtained re-marked construction building part, and sum the calculated overlapping areas. The summation result is recorded as S ijt, [1-exp(-S ijt )]*F ijt As the influence coefficient of the j-th construction zone in the building layer numbered i on the construction zone adjacent to the j-th construction zone in the building layer numbered i at time t, if the shortest distance value between construction zone A and construction zone B is 0, then construction zone B is called the adjacent construction zone of construction zone A or construction zone A is the adjacent construction zone of construction zone B, where exp represents an exponential function with a real number e as the base and e=2.72;

[0075] S204: When 0<F ijt ≤1, the abnormality value F of the jth construction zone in the building layer numbered i at time t is ijt , the influence coefficient of the j-th construction zone in the building layer numbered i on the construction zone adjacent to the j-th construction zone in the building layer numbered i at time t [1-exp(-S ijt )]*F ijt Recorded in the inspection report template of the construction site;

The F values participating in the sorting process are not 0. (X ij , Y ijt ) represents the central coordinates of the j-th construction sub-region on the i-th building floor. Generate the inspection plan K for the construction site at time t according to the sorted sequence K ij , and the inspection order of the inspection plan K ij t t is: the construction sub-region corresponding to the first item of the sorted sequence K → the construction sub-region corresponding to the second item of the sorted sequence K → … → the construction sub-region corresponding to the last item of the sorted sequence K. The principle of the nearest distance to the journey means that when there are multiple cases with the same abnormal degree value (inspection index), all the construction sub-regions corresponding to the same abnormal degree value (same inspection index) are obtained, and the abnormal degree value

[0083] (inspection index) corresponding to the construction sub-region Q in the previous sorting position is determined. The abnormal degree value (inspection index) in the previous sorting position corresponding to the same abnormal degree value (same inspection index) ≠ the same abnormal degree value (same inspection index). Based on the journey values of the inspection personnel from the construction sub-region Q to each obtained construction sub-region, the same abnormal degree value (same inspection index) is sorted using the principle of the nearest distance;

[0084] S304: When [1 - exp(-S ght )]*F ght ≠ 0, if [1 - exp(-S ijt )]*F ijt
