Description

Technical Field

[0001] The present invention belongs to the technical field of floor tile laying, and in particular relates to a system and method for quickly laying electrostatic floors in a data center based on BIM technology. Background Art

[0002] In recent years, with the rapid development of information technology, data centers have become an indispensable part of construction projects, and the layout of static floor in data centers is a crucial link. At present, the conventional BIM technology static floor layout method generally uses Autodesk Revit software to establish a conventional model of static floor, and then arranges it by manually placing the static floor. At the same time, the user must determine the concession relationship of the static floor by checking the two-dimensional drawing specifications, which is time-consuming and laborious; and the existing static floor layout algorithm based on BIM technology still has problems in accuracy and efficiency when dealing with complex terrain and large-scale static floor layout; when encountering non-whole floor, it is necessary to repeat the modeling separately, which takes a lot of time; at the same time, if the layout plan or floor size changes, a large area adjustment is required, which will lead to extremely low layout efficiency, inefficient data management, and inaccurate material consumption statistics. Therefore, the present invention designs a new type of data center static floor rapid layout system and method based on BIM technology to improve the efficiency and accuracy of floor layout and reduce construction costs and error rates. Summary of the invention

[0003] In view of the shortcomings in the prior art, the present invention provides a system and method for rapid layout of electrostatic floors in data centers based on BIM technology, which can automatically perform rapid layout of electrostatic floors, generate corresponding detailed quantity lists and floor layout construction drawings, and guide construction personnel to lay the floors, thereby improving the efficiency and accuracy of floor layout and reducing construction costs and error rates.

[0004] The present invention achieves the above technical objectives through the following technical means.

[0005] A rapid layout system for electrostatic floor in a data room based on BIM technology comprises an electrostatic floor layout module, a material statistics module and a construction scheme simulation module; the electrostatic floor layout module is used to automatically calculate the best layout plan for the electrostatic floor, the material statistics module is used to perform electrostatic floor engineering quantity statistics on the room model where the electrostatic floor is laid out, generate an electrostatic floor engineering quantity list, and guide material cutting and processing; the construction scheme simulation module produces a construction simulation animation based on the BIM model of the data room, and produces a construction technology briefing document in combination with detailed screenshots of the model and relevant electrostatic floor layout construction specification materials.

[0006] The method for quickly laying out the static floor in a data room based on BIM technology, using the above-mentioned system for quickly laying out the static floor in a data room based on BIM technology, includes the following process:

[0007] Step 1: Create a BIM model of the data center based on Autodesk Revit software, and import the BIM model data into the static floor laying module;

[0008] Step 2: The static floor laying module first extracts the detailed geometric data of the ground from the BIM model, including the shape, size, inclination and height change of the ground; then sets the physical parameters of the static floor, including size, shape, thickness, material and texture;

[0009] Step 3: The electrostatic floor layout module calculates the best layout plan of the electrostatic floor based on the BIM model and the electrostatic floor information using the electrostatic floor layout algorithm;

[0010] Step 4: Based on the static floor layout plan generated in step 3, a three-dimensional visualization is presented in Autodesk Revit software for review by relevant personnel. At the same time, relevant personnel manually adjust the static floor layout plan to meet specific design requirements or construction conditions;

[0011] Step 5: Generate construction guidance documents based on the static floor laying plan finally determined in step 4;

[0012] Step 6: The material statistics module performs static floor engineering quantity statistics on the static floor laying plan model generated in step 5, generates a static floor engineering quantity list, and centrally cuts and processes the incomplete static floor based on it, and places static floor materials at fixed points and in fixed quantities;

[0013] Step 7: Use the construction plan simulation module to produce a construction simulation animation. After the construction simulation animation is completed, combine the model detail screenshots to produce a construction technology briefing document.

[0014] Furthermore, the specific process of step 3 is as follows:

[0015] Step 3.1: Preprocessing and parameter setting: Extract the ground 3D data and detailed specifications of the electrostatic floor from the BIM model;

[0016] Step 3.2: Selection of the laying mode of the electrostatic floor: According to the ground data extracted in step 3.1, the initial position and laying direction of the electrostatic floor are determined, and the laying mode of the electrostatic floor is selected by using rule-based decision logic;

[0017] Step 3.3: Use Dijkstra algorithm to calculate the optimal layout path;

[0018] Step 3.4: Material optimization calculation: According to the optimal path for laying the electrostatic floor generated in step 3.3, the cutting and use of the electrostatic floor are optimized through linear programming to minimize material waste;

[0019] Step 3.5: Refine the final static floor layout plan, including: for layout areas with special shapes, decompose the complex areas into simple sub-areas, calculate the optimal layout plans respectively, and then integrate these sub-plans. At the same time, adjust the size of the edge static floor to adapt to the irregular boundaries, further optimize the layout plan and improve material utilization.

[0020] Furthermore, the specific process of step 3.3 is as follows:

[0021] Step 3.3.1: Generate the layout area and divide the grid according to steps 3.1 and 3.2. Each grid unit corresponds to a layout electrostatic floor position:

[0022] The number of grid cells N along the length direction:

[0023] The number of mesh elements M along the length direction:

[0024] Among them, L and W are the length and width of the laying area; l and w are the dimensions of the selected laying electrostatic floor, represents the ceiling function;

[0025] Step 3.3.2: Use Dijkstra algorithm to calculate the optimal laying path. The Dijkstra algorithm is used to find the shortest laying path given the initial position and laying direction of the electrostatic floor in step 3.2. The vertex of the graph represents the starting point of the laying, and the weight of the edge represents the difficulty or cost of the laying.

[0026] Dijkstra's algorithm is as follows:

[0027] Let G(V,E) be a graph, where V is the vertex set, E is the edge set, and each edge (u,v)∈E has a non-negative weight w(u,v). Let d[v] represent the shortest path from the starting point to the vertex v, initialized to infinity, except that the starting point itself is initialized to 0. The algorithm repeatedly selects the vertex u with the smallest d[v] value and updates all adjacent vertices v of u, that is,

[0028] d[v]=min(d[v],d[u]+w(u,v)), where d[u] represents the shortest path from the starting point to vertex u.

[0029] Furthermore, the specific process of step 3.4 is as follows:

[0030] According to the optimal path for laying the electrostatic floor generated in step 3.3, linear programming is used to optimize the cutting and use of the electrostatic floor to minimize material waste: define the objective function to minimize the cutting and waste of the electrostatic floor while satisfying the coverage constraints of the laying area:

[0031] Objective function:

[0034] The present invention has the following beneficial effects:

[0035] When the present invention is used to lay out the electrostatic floor, the efficiency and accuracy of the electrostatic floor arrangement are greatly improved, and the construction cost and error rate are reduced; at the same time, the system designed based on the present invention can also perform manual electrostatic floor laying adjustments according to actual conditions to meet special needs, avoid material loss problems in previous construction processes, achieve refined management of the construction process, optimize configuration, improve construction quality, reduce secondary handling, reduce losses, eliminate unnecessary rework in advance, shorten construction period, reduce material waste, improve economic benefits, maximize resource utilization, and achieve refined management of the construction process.

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0038] The system and method for fast laying out the static floor in a data center based on BIM technology of the present invention include a static floor laying module, a material statistics module, and a construction scheme simulation module. The static floor laying module automatically calculates the best static floor laying scheme based on the static floor layout algorithm; the material statistics module is used to count the static floor engineering quantity of the room model where the static floor is laid out, and generate a detailed list of static floor engineering quantities; the construction scheme simulation module produces a construction simulation animation based on the BIM model, and produces a construction technology briefing document in combination with the model detail screenshots and relevant static floor layout construction specification materials.

[0039] Using the system and method for rapid laying of static floor in a data center based on BIM technology, Figure 1 As shown, the specific process includes the following:

[0040] Step 1: Based on Autodesk Revit software, a 3D model of the data center is established, namely the data center BIM model (hereinafter referred to as the BIM model), and the BIM model data is imported into the static floor laying module; the BIM model contains all the structures and details of the data center, including the ground, walls, doors and windows;

[0041] Step 2: The static floor laying module first extracts the detailed geometric data of the ground from the BIM model, including the shape, size, inclination and height change of the ground; then sets the physical parameters of the static floor, including size, shape, thickness, material and texture;

[0042] Step 3: The electrostatic floor layout module calculates the best layout plan of the electrostatic floor based on the BIM model and the electrostatic floor information using the electrostatic floor layout algorithm. The specific process is as follows:

[0043] Step 3.1: Preprocessing and parameter setting: Extract the ground three-dimensional data (including the coordinates and normal vectors of each point) and the detailed specifications of the electrostatic floor (such as size, shape, texture) from the BIM model;

[0044] Step 3.2: Paving mode selection: According to the ground data extracted in step 3.1, determine the initial position and laying direction of the electrostatic floor, and use rule-based decision logic to select an appropriate laying mode, such as straight laying, staggered laying and herringbone laying;

[0045] Step 3.3: Calculation of optimal layout path:

[0046] Step 3.3.1: Generate a layout area according to step 3.1 and step 3.2 for grid division, where each grid unit corresponds to a layout electrostatic floor position;

[0047] The number of grid cells N along the length direction:

[0048] The number of mesh elements M along the length direction:

[0049] Among them, L and W are the length and width of the laying area; l and w are the dimensions of the selected laying electrostatic floor, represents the rounding-up function, ensuring that the layout area is fully covered, even though the last row or column of electrostatic flooring may need to be cropped to fit the border;

[0050] Step 3.3.2: Use Dijkstra algorithm to calculate the optimal laying path. The Dijkstra algorithm is used to find the shortest laying path given the initial position and laying direction of the electrostatic floor in step 3.2, where the vertex represents the starting point of the laying and the weight of the edge represents the difficulty or cost of the laying;

[0051] Dijkstra's algorithm is as follows:

[0052] Let G(V,E) be a graph, where V is the vertex set, E is the edge set, and each edge (u,v)∈E has a non-negative weight w(u,v). Let d[v] represent the shortest path from the starting point to the vertex v, initialized to infinity, except that the starting point itself is initialized to 0. The algorithm repeatedly selects the vertex u with the smallest d[v] value and updates all adjacent vertices v of u, that is,

[0053] d[v]=min(d[v],d[u]+w(u,v)), where d[u] represents the shortest path from the starting point to vertex u;

[0054] Step 3.4: Material optimization calculation:

[0055] According to the optimal path for laying the electrostatic floor generated in step 3.3, the cutting and use of the electrostatic floor are optimized through linear programming (LP) to minimize material waste;

[0056] Define the objective function to minimize the cutting and waste of the electrostatic floor while satisfying the coverage constraint of the layout area:

[0057] Objective function:

[0058] Constraints:

[0059] Among them, c j represents the objective function coefficient, x j represents the decision variable, a ij represents the constraint matrix coefficient, b iRepresents the right-hand side value of the constraint; i represents the i-th size of floor tile; m represents the number of different floor tile sizes; j represents the j-th paving area; n represents the number of paving areas.

[0060] Step 3.5: Refine the electrostatic floor layout plan generated by steps 3.3 and 3.4, including: for layout areas of special shapes (such as L-shape and T-shape), adopt a divide-and-conquer strategy to decompose the complex area into simple sub-areas, calculate the optimal layout plan separately, and then integrate these sub-plans. At the same time, adjust the size of the edge electrostatic floor to adapt to the irregular boundary, further optimize the layout plan and improve material utilization.

[0061] Step 4: Based on the static floor layout plan generated in step 3, a three-dimensional visualization is performed in Autodesk Revit software. Designers and construction workers can intuitively see the layout effect of the static floor. If necessary, the layout plan can be manually adjusted to meet specific design requirements or construction conditions.

[0062] Step 5: Generate a construction guidance document based on the static flooring layout plan finalized in step 4. The construction guidance document contains detailed information such as the specific location, direction, and splicing method of each static floor, which will be used to guide construction personnel in the actual static flooring layout work.

[0063] Step 6: The material statistics module performs static floor quantity statistics on the static floor layout model generated in step 5, and generates a detailed list of static floor quantity. Based on this, the incomplete static floor is centrally unloaded and processed, and the static floor materials are placed at fixed points and in fixed quantities to reduce the secondary handling of materials.

[0064] Step 7: Use the construction plan simulation module to produce a construction simulation animation. After the construction simulation animation is completed, combine the model detail screenshots to produce a construction technology briefing document.

[0065] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
