Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus, equipment, and storage medium for allocating tower crane components to building components. Background Technology

[0002] In the construction industry, tower crane hoisting tasks are primarily generated manually. For example, construction workers open the design drawings, find the component numbers, manually enter them into the management system, select the tower crane's coverage area, determine if the component is within that area, and finally assign the component to the corresponding tower crane based on their experience. However, this identification and entry method is time-consuming and labor-intensive. Matching the tower crane's coverage area with the component's location relies entirely on manual experience, making task assignment errors prone to occur.

[0003] Therefore, how to automatically convert the coordinates of building components on the design drawings into coordinates on the construction site and intelligently assign them to the corresponding tower cranes has become a technical problem that urgently needs to be solved by those skilled in the art.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0018] Example 1 This invention provides a method for allocating tower cranes to building components, such as... Figure 1 As shown, the method specifically includes the following steps: Step S101: Obtain the design drawings corresponding to the construction site.

[0019] In this embodiment, the design drawings are typically CAD drawings, which use a drawing coordinate system, preferably a two-dimensional Cartesian coordinate system. The construction site uses a geographic coordinate system, which refers to the coordinate system obtained through on-site surveying (such as radar scanning or total station measurement) that corresponds to the actual physical location of the construction site. The CAD drawings include the drawing coordinates of the building components and their corresponding component codes, with each building component corresponding to a unique component code, for example: PCW202, YZQ001.

[0020] Step S102: Calculate the coordinate transformation matrix based on the coordinate positions of multiple preset fixed reference objects in the design drawings and the geographical coordinate positions in the construction site.

[0021] In this embodiment, the fixed reference object is a feature point that can be clearly identified and is not easily changed in both the design drawings and the construction site, such as: building corner points, axis intersections, and embedded benchmark points. Preferably, this embodiment requires three accurate fixed reference objects.

[0022] Step S103: Calculate the geographical coordinates of each building component in the design drawings at the construction site using the coordinate transformation matrix.

[0023] In this embodiment, the coordinates of each building component on the drawing are multiplied by the coordinate transformation matrix to obtain the geographical coordinates of the building component at the construction site. The geographical coordinates of the component are then bound to its component code, ensuring that the positioning accuracy of the component at the construction site is controlled within five centimeters, fully meeting the stringent positioning accuracy requirements of tower crane hoisting. This solves the problem of the lack of an automated coordinate mapping bridge between CAD design drawings and the construction site management system, which easily introduces errors and results in low efficiency.

[0024] Step S104: Obtain the geographical coordinates and coverage area information of each tower crane in the construction site.

[0025] In this embodiment, the tower crane's coverage area will theoretically cover the entire circumference of the boom. However, in actual construction sites, it will be affected by other site factors, such as buildings blocking the view, resulting in a geometric shape for the coverage area.

[0026] Step S105: Assign a unique tower crane to each building component based on the geographical coordinates of each building component, the geographical coordinates of each tower crane, and the coverage area information.

[0027] In this embodiment, based on the criterion of "a point within a polygon," building components located within the coverage area of ​​a tower crane are assigned to that tower crane. After all building components are assigned to tower cranes, a structured hoisting task list is generated by classifying and sorting them according to the tower crane. The task list includes the code of each tower crane, the component code of the building component assigned to that tower crane, and its geographical coordinates. This ensures that the assigned tasks are within the physical capabilities of the tower cranes, overcoming the inconsistencies and limitations of human experience.

[0028] In this embodiment, by acquiring the design drawings corresponding to the construction site, the information of building components is efficiently and accurately extracted from the design drawings; based on the coordinate positions of multiple preset fixed reference objects in the design drawings and their geographical coordinate positions in the construction site, a coordinate transformation matrix is ​​calculated, and the geographical coordinate positions of each building component in the design drawings in the construction site are calculated using the coordinate transformation matrix, automatically mapping the coordinates of the design drawings to the coordinates of the construction site with high precision; the geographical coordinate positions and coverage area information of each tower crane in the construction site are acquired, and a unique tower crane is assigned to each building component based on the geographical coordinate positions of each building component, the geographical coordinate positions of each tower crane, and their coverage area information, thus solving the problem of intelligent allocation of tower crane hoisting tasks in multi-tower crane collaborative operation scenarios.

[0029] Specifically, after obtaining the design drawings corresponding to the construction site in step S101, the method further includes: Step A1: Collect click operations, determine the target layer where the target building component corresponding to the click operation is located, and obtain each building component from the target layer; or, Step A2: Use an image recognition algorithm to identify the design drawings, obtain the outline feature information of each building component, and use a preset component database to determine each building component.

[0030] In this embodiment, when a user selects any target building component in a CAD drawing, all text information in the text layer containing that target building component will be displayed. This text information includes the component code and drawing coordinates of each building component. When the text information in the CAD drawing is unclear or is written to another layer due to improper operation, the component codes of some building components cannot be recognized. Image recognition is used to identify the CAD drawing and compare it with a preset component database according to the component outline to obtain the component code and drawing coordinates of each building component. This avoids the errors and omissions that inevitably occur during manual identification and data entry, and generates a binding table containing component codes and drawing coordinates, laying the foundation for subsequent processing.

[0031] Specifically, in step S102, the coordinate transformation matrix is ​​calculated based on the coordinate positions of multiple preset fixed reference objects in the design drawings and the geographical coordinate positions in the construction site, including: Step B1: Obtain the coordinate positions of three fixed reference objects on the design drawings and their geographical coordinate positions on the construction site. Step B2: Form a set of coordinate point pairs by combining the drawing coordinate position and geographical coordinate position of each fixed reference object, so as to obtain three sets of coordinate point pairs; Step B3: Input the three sets of coordinate point pairs into the affine transformation algorithm to obtain the initial transformation matrix; Step B4: Input the initial transformation matrix into the least squares algorithm to obtain the coordinate transformation matrix. ; Where a, b, c, d, e, and f are the transformation parameters in the coordinate transformation matrix; Parameters a and e together control the coordinate scaling transformation from the design drawings to the construction site; submatrix Jointly control the coordinate rotation transformation from the design drawings to the construction site; Parameters b and d together control the coordinate shearing transformation from the design drawings to the construction site; Parameters c and f together control the coordinate translation transformation from the design drawings to the construction site.

[0032] In this embodiment, the drawing coordinates of each fixed reference object in the design drawings and its geographical coordinates at the construction site form a set of coordinate point pairs, such as (P_cad, P_site), where P_cad represents the drawing coordinates and P_site represents the geographical coordinates. Inputting these three sets of coordinate point pairs into an affine transformation algorithm and optimizing them using the least squares method yields a coordinate transformation matrix that optimally fits the drawing coordinates of the fixed reference object to the geographical coordinates of the construction site. .

[0033] This transformation matrix integrates multiple transformations: parameter a represents the scaling factor in the x-axis direction, parameter b represents the shearing factor in the x-axis direction, parameter c represents the translation in the x-axis direction, parameter d represents the shearing factor in the y-axis direction, parameter e represents the scaling factor in the y-axis direction, and parameter f represents the translation in the y-axis direction; parameters a and e together control the coordinate scaling transformation from the design drawings to the construction site; submatrices The system jointly controls the coordinate rotation transformation from the design drawings to the construction site; parameters b and d jointly control the coordinate shearing transformation from the design drawings to the construction site; and parameters c and f jointly control the coordinate translation transformation from the design drawings to the construction site. By using an affine transformation algorithm for coordinate transformation, it fundamentally eliminates hoisting errors caused by discrepancies between the "position on the drawings" and the "position on the construction site," achieving an accuracy of ±5 cm and ensuring that design information is transmitted to the construction execution stage without loss and with precision.

[0034] In addition to the affine transformation algorithm, this embodiment can also employ more complex models such as quadratic polynomial transformation or thin-plate spline functions to address nonlinear errors such as on-site foundation deformation. For example, the quadratic polynomial transformation method is as follows: To obtain fixed reference objects, users need to select at least six pairs of evenly distributed fixed reference object coordinates (X_cad_i, Y_cad_i) and (X_site_i, Y_site_i) on CAD design drawings and construction site maps. The system uses the following mathematical model to establish the mapping relationship: X_site=a0+a1*X_cad+a2*Y_cad+a3*X_cad²+a4*X_cad*Y_cad+a5*Y_cad²; Y_site=b0+b1*X_cad+b2*Y_cad+b3*X_cad²+b4*X_cad*Y_cad+b5*Y_cad².

[0035] Among them, a0, a1, ..., a5 and b0, b1, ..., b5 are the 12 transformation coefficients to be determined.

[0036] A linear system of equations is constructed and solved by substituting each coordinate point into the above equations, resulting in a linear system of equations A * x = B, where: A is a coefficient matrix composed of the coordinates from the CAD drawing and their quadratic terms; x is the 12-dimensional coefficient vector [a0, a1, ..., a5, b0, b1, ..., b5]^T to be solved; and B is a vector composed of all the coordinates on site. When the number of coordinate points is greater than 6, the system uses the least squares method to solve this overdetermined system of equations, obtaining a set of optimal coefficients that minimize the overall error.

[0037] Coordinate batch transformation and accuracy assessment: Using the 12 solved coefficients, the system can perform batch transformation of the CAD drawing coordinates (X_cad, Y_cad) of each component and calculate its corresponding site coordinates (X_site, Y_site).

[0038] The thin-plate spline function method is as follows: To obtain fixed reference objects, the user needs to provide at least three pairs of coordinate points for those fixed reference objects (but usually more are needed to constrain complex deformations). The number and quality of the points directly determine the shape of the transformation. The system receives coordinate point pairs (X_cad_i, Y_cad_i) and (X_site_i, Y_site_i).

[0039] The mathematical model is constructed and the coefficients are solved. The formula for the TPS model is as follows: X_site=a0+a1*X_cad+a2*Y_cad+Σ(w_i*U(||P_cad-P_cad_i||)) (Similarly, the Y-coordinate has another set of coefficients b0, b1, b2, v_i).

[0040] Where U(r) = r² * log(r) is the radial basis function of the thin plate spline (r is the Euclidean distance between two points). a0, a1, a2 are the coefficients of the global affine transformation. w_i is the nonlinear deformation weight coefficient corresponding to each coordinate point.

[0041] Solving the TPS model requires solving a system of linear equations, which consists of two constraints: interpolation condition: the transformed coordinates must be exactly equal to the field coordinates; boundary condition: the sum of the weight coefficients w_i is zero, and they are orthogonal to the coordinates of the points, to ensure the uniqueness and smoothness of the solution. By solving this large system of linear equations, the system obtains all affine coefficients (a, b) and weight coefficients (w, v) in one step.

[0042] For coordinate transformation, for any CAD drawing coordinate P_cad of a building component to be transformed, the system substitutes it into the solved TPS model: calculates the distance r_i from this point to every coordinate point P_cad_i. Using the radial basis function U(r_i) and the obtained weight coefficient w_i, the nonlinear deformation of this point is calculated. This deformation is added to the global affine part to obtain the final, accurate on-site coordinates.

[0043] Specifically, obtaining the geographical coordinates and coverage area information of each tower crane at the construction site in step S104 includes: Step C1: Calculate the rotation area of ​​each tower crane using the length of its boom and the rotation angle on site; Step C2: Calculate the coverage area information of each tower crane using its geographical coordinates and corresponding rotation area.

[0044] In this embodiment, each tower crane has a unique corresponding code. The geographical coordinates of the base, boom length, and rotation angle of each tower crane are obtained from the database. First, the rotation area of ​​each tower crane is calculated. Then, based on the geographical coordinates of the tower crane, it is determined whether there are any obstacles obstructing the rotation area, thus obtaining the actual coverage area of ​​the tower crane on the construction site. Abstract parameters such as boom length and lifting capacity curves are transformed into specific, calculable spatial coverage areas, thereby ensuring that the tasks assigned by the system are within the physical capabilities of the tower crane and eliminating potential safety hazards at the source.

[0045] Specifically, in step S105, assigning a unique tower crane to each building component based on the geographical coordinates of each building component, the geographical coordinates of each tower crane, and the coverage area information includes: Step D1: For a building component, determine whether the geographical coordinates of the building component are located only within the coverage area of ​​a single tower crane; Step D2: If so, assign the building component to the tower crane; Step D3: If not, assign the building component to the tower crane closest to the building component, or assign the building component to the tower crane with the least workload within the coverage area of ​​the multiple tower cranes where the building component is located.

[0046] In this embodiment, each building component can only be assigned to one tower crane. When multiple tower cranes are working together, the spatial position relationship between each building component and each tower crane is calculated. First, it is determined whether the geographical coordinates of the building component are located within the coverage area of ​​only one tower crane. If so, the building component is directly assigned to that tower crane. If not, the building component is located within the overlapping area of ​​multiple tower crane coverage polygons. In this case, it is assigned to the nearest tower crane according to the minimum distance principle, or to the tower crane with less workload according to the load balancing principle, thus assigning a unique tower crane to each building component. This automates and algorithms the complex judgment work that relies most on personal experience, achieving load balancing and path optimization for tower crane hoisting tasks.

[0047] In this embodiment, as Figure 2 As shown, when assigning hoisting tasks, users log into their accounts on the intelligent equipment management platform (such as the underlying platform of the task generation tool and task scheduling center), select to assign tower crane projects to building components, and obtain project information, tower crane parameters, and a map of the construction site. Users import CAD design drawings and click on the target building component. This displays all building components of the same type as the target component in the layer. Users select an area to obtain the component codes and drawing coordinates of each component within that area. Then, three fixed reference objects are selected as mapping points, and three sets of coordinate point pairs for each fixed reference object are determined from the CAD design drawings and the construction site. These are input into an affine transformation algorithm to obtain a coordinate transformation matrix, thus mapping the drawing coordinates of each building component to the geographical coordinates of the construction site. Finally, based on the geographical coordinates of each building component, suitable tower cranes are automatically assigned according to factors such as the tower crane's lowering position, load balancing, and geographical coordinates, and a hoisting task list is generated and pushed to the scheduling system.

[0048] In this embodiment, the beneficial effects achieved by all the above technical solutions are as follows: The entire chain from drawing recognition to task generation is automated, freeing manual labor from tedious and repetitive tasks; Component allocation is performed through built-in algorithms, overcoming the inconsistencies and limitations of human experience, especially in multi-tower crane scenarios, enabling load balancing and path optimization for hoisting tasks, thus improving overall construction efficiency; A strict coordinate mapping model ensures the consistency between "design" and "construction" coordinates, eliminating hoisting problems caused by coordinate errors at the source, with accuracy down to the centimeter level; Data flow between the CAD design end and the construction management end is streamlined, enabling lossless transmission of design information to the construction execution stage, laying a solid foundation for digital construction and lean management.
