Description

Technical Field

[0001] This invention relates to the field of photovoltaic design technology, and in particular to an airport photovoltaic planning and design method based on BIM model. Background Technology

[0002] Airport photovoltaic (PV) arrays consist of PV modules (panels), supports, cables, inverters, etc. The PV modules and supports are the main components affecting airport airspace clearance. During airport PV planning and design, within the airport's clearance clearance zone, in addition to determining the PV array's layout based on factors such as sunlight, land conditions, glare, and electromagnetic interference, it's also necessary to select appropriate tilt angles and ground clearance for the PV modules and supports to ensure the PV panels receive sufficient solar radiation throughout the year. When the PV array's airspace clearance meets requirements, the tilt angle of the PV panels may be adjusted to receive sufficient solar radiation, potentially leading to airspace clearance exceeding limits and requiring re-verification. Furthermore, there may be obstructions from the front and rear, necessitating adjustments to the support's ground clearance, which in turn may again result in airspace clearance exceeding limits and require re-verification. In short, the design of PV modules requires continuous adjustments to their tilt angle and ground clearance to ensure sufficient solar radiation and avoid obstructions from the front and rear, while simultaneously conducting airspace clearance verification. The airspace clearance verification results are a key control element in PV design, and this process is cyclical. Currently, the main method for airspace clearance verification is to manually obtain the geometric center elevation of each PV module and perform individual verifications.

[0003] As can be seen from the aforementioned methods and approaches for airspace verification during airport photovoltaic planning and design, airport photovoltaic modules have a tilt angle (not flat), and the geometric center elevation of the module cannot represent the maximum elevation of the entire module. This can easily lead to misjudgments in airspace verification results, posing a significant risk to airport safety. Furthermore, airport photovoltaic modules are numerous (for example, one airport has a photovoltaic installation capacity of 65.87 MWh). WP For example, with approximately 5312 photovoltaic modules, manual verification of each module is prone to omissions, heavily influenced by human subjectivity, and the results cannot quickly adapt to changes in the plan. Clearly, this is time-consuming, labor-intensive, and inefficient. Therefore, exploring a method that allows for rapid adjustment of the tilt angle and ground clearance of photovoltaic modules while also enabling rapid clearance verification is particularly important.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] According to the first embodiment of the present invention, referring to Figure 1 This invention claims protection for an airport photovoltaic planning and design method based on a BIM model, comprising: S101, Obtain the planning layout requirements of the photovoltaic panel module to be planned and designed, and obtain the layout logic relationship of the photovoltaic panel module to be planned and designed based on the planning layout requirements; S102, based on the input layout logic relationship, expression and API function of the photovoltaic panel components to be planned and designed, compile the set relationship of the photovoltaic panel components to be planned and designed to obtain the parameterized photovoltaic panel components; S103, Based on the parameterized photovoltaic panel assembly, create a three-dimensional parameterized dynamic model of the photovoltaic panel assembly to be planned and designed, and obtain the three-dimensional parameterized surface of the top of the photovoltaic panel assembly to be planned and designed. S104, using the three-dimensional parametric surface at the top of the photovoltaic panel as a reference surface, perform a height difference analysis with the clearance restriction surface, and perform a synchronous height limit verification between the top surface of the photovoltaic panel and the clearance restriction surfaces of each area to verify whether the layout of the photovoltaic panel to be planned and designed exceeds the height or has redundant height.

[0017] Furthermore, S101 also includes: The photovoltaic panel assembly to be planned and designed includes at least a photovoltaic support frame to be planned and designed and a photovoltaic panel to be planned and designed. The planning layout requirements include at least a first set of planning layout requirements and a second set of planning layout requirements; Based on the first set of planning and layout requirements, the first layout logic relationship of the photovoltaic bracket to be planned and designed is obtained; Based on the second set of planning and layout requirements, the second layout logic relationship of the photovoltaic panels to be planned and designed is obtained; Based on the first and second deployment logic relationships, the clearance is checked again.

[0018] Furthermore, S102 also includes: Secondary development is carried out based on the Autodesk platform, and the photovoltaic module set relationship is compiled based on the layout logic relationship, expression and API function of the photovoltaic support and photovoltaic panel to be planned and designed. Based on the target parameters and condition parameters, the relationship between the photovoltaic panel module to be planned and designed and the terrain and geology is defined. The cross section of the photovoltaic panel module to be planned and designed is compiled into a parameterized component and assigned code. Perform parametric dynamic design of the photovoltaic bracket and photovoltaic panel to be designed, and obtain the parametric photovoltaic panel component by customization.

[0019] In this embodiment, based on the Autodesk platform, the structural data and computational characteristic data of the input photovoltaic panels and photovoltaic brackets are used as layout logic relationships, expressions and API functions to compile the photovoltaic module set relationship. The relationship between the photovoltaic modules and the terrain is defined based on target parameters and condition parameters. By assigning line (connection) code and shape (modeling) code, the cross-section of the photovoltaic module is compiled into parametric components, and a three-dimensional parametric surface on the top of the photovoltaic panel module is constructed.

[0020] The compilation of component code for photovoltaic modules specifically includes: when compiling components, specifying attributes for the resulting geometric lines and regions in the form of double quotes followed by content, such as "top of photovoltaic panel".

[0021] Furthermore, S103 also includes: Import the parameterized photovoltaic panel component into civil3D software; A three-dimensional parametric dynamic model of the photovoltaic panel module to be planned and designed is created using the road modeling method, adapting to the terrain conditions. The top three-dimensional parametric surface of the photovoltaic panel module to be planned and designed is obtained based on the three-dimensional parametric dynamic model.

[0022] In this embodiment, the “_ToolPalettes” command is invoked to import the “photovoltaic module” component into the Civil 3D model space. The “_AeccCreateAlignmentEntity” command in the Civil 3D software is invoked to select the center line of the photovoltaic module and the route of the photovoltaic module 3D model. Then, the “_AeccCreateProfileFromSurface” command is invoked to cut the terrain surface with the route of the photovoltaic module 3D model to create the longitudinal section of the photovoltaic module 3D model.

[0023] Furthermore, the method also includes: The first planning layout requires the set to include at least policy information and airspace conditions; The second planning layout requires the collection to include at least electromagnetic glare information and power generation benefits; The first deployment logic relationship includes at least the height and tilt angle of the photovoltaic support to be planned and designed; The second layout logic relationship includes at least the tilt angle of the photovoltaic panel to be planned and designed.

[0024] In this embodiment, policy information refers to regional restrictions on the height of photovoltaic panels. Clearance requirements: Different locations will have different requirements for the height and tilt angle of photovoltaic panels.

[0025] Electromagnetic interference and glare: This refers to the electromagnetic interference or glare caused by the height and angle of the photovoltaic panel during flight operations. These are generally boundary conditions provided by other disciplines.

[0026] Reference Figure 2 This involves parameterizing photovoltaic (PV) modules. By setting key control points for PV brackets and PV panels, and combining API functions with logical judgment conditions, the system intelligently handles and constructs different shapes and relationships of PV modules. The main logical expressions are as follows: (1) P1: Delta X and Delta Y (default: 0,0); (2) P2: from P1, Slope and Delta Y (input parameters: "slope", "support height"); (3) P3: from P2, Slope and Delta X (input parameters: "slope", "half the length of the photovoltaic panel"); (4) P4: from P2, Slope and Delta X (input parameters: "slope", "half the length of the photovoltaic panel"); (5) P5: from P4, Angle and Distance (input parameters: "angle", "photovoltaic panel thickness"); (6) P6: from P3, Angle and Distance (input parameters: "Angle", "Photovoltaic panel thickness").

[0027] In expression (1), “P1” is the origin of the component, which is the assembly positioning point in the model and also the bottom point of the photovoltaic bracket. It is generally used to locate the center line of the bottom of the photovoltaic bracket. Expression (2), “P2” is the top point of the photovoltaic bracket, which is used to judge the subsequent conditions of photovoltaic panel connection. Expression (3), “P3” is the bottom point of the front edge of the photovoltaic panel. Expression (4), “P4” is the bottom point of the rear edge of the photovoltaic panel. Expression (5), “P5” is the top point of the rear edge of the photovoltaic panel. Expression (6), “P6” is the top point of the front edge of the photovoltaic panel. “P1”, “P2”, “P3”, “P4”, “P5”, and “P6” will form the outline of the photovoltaic module by establishing the photovoltaic module shell during model assembly.

[0028] Furthermore, the layout logic relationship between the photovoltaic support structure to be planned and the photovoltaic panels to be planned and designed also includes: The length, thickness, and surface tilt angle of the photovoltaic panel to be planned and designed; The height, tilt angle, and width of the photovoltaic support structure to be planned and designed; The target parameters include at least surface parameters, which include at least terrain surfaces and photovoltaic panel top surfaces. The condition parameters include at least the judgment conditions and loop conditions required to generate the geometry of the photovoltaic module to be planned and designed.

[0029] In this embodiment, such as Figure 3 The photovoltaic module model and the top 3D parametric surface of the photovoltaic panel are created based on component compilation; this is achieved through geometric code allocated during component compilation. Geometric link codes are assigned, and the photovoltaic module model is assembled in the BIM software. Based on the top links “P5” and “P6”, the top 3D parametric surface of the photovoltaic panel is generated in the BIM software.

[0030] Furthermore, the step of obtaining the top three-dimensional parametric surface of the photovoltaic panel module to be planned and designed based on the three-dimensional parametric dynamic model also includes: The top of the three-dimensional parametric dynamic model is connected, and the outer edge is used as the boundary to generate the top three-dimensional parametric surface of the photovoltaic panel module to be planned and designed.

[0031] like Figure 4 Call the "_AeccCreateAssembly" command to create a 3D model cross-section assembly of the photovoltaic module, and call the "CreateSubAssemblyTool" command to load the photovoltaic module component into the cross-section assembly.

[0032] like Figure 5 Based on the 3D model route, longitudinal section, and cross section of the photovoltaic module, the Civil3D road method is used to call the "_AeccCreateCorridor" command to create a 3D parametric reference model of the photovoltaic module, and the top of the model is connected, with the outer edge as the boundary, to generate a 3D parametric surface on the top of the photovoltaic module.

[0033] like Figure 6 The height difference analysis is performed on the three-dimensional parametric surface at the top of the photovoltaic panel module and the clearance surface to quickly respond to changes in the scheme caused by electromagnetic and glare analysis and to create conditions for clearance verification.

[0034] Furthermore, S104 also includes: Invoke the "_AeccShowTabSurfaceNoSel" command in the Civil 3D software and select the "Surface" function module in the menu bar; Call “_MinimumDistBetweenSurfaces”, select the “Minimum Distance Between Surfaces” command in the menu bar, and convert the three-dimensional parametric surfaces on the top of the photovoltaic panel module to be planned and designed. Perform a Boolean operation on the minimum distance between the three-dimensional parametric surface and the clearance surface to obtain the height difference between the three-dimensional parametric surface and the clearance surface at the top of the photovoltaic panel module to be planned and designed. Then, perform a synchronous height limit check on the top surface of the photovoltaic panel module to be planned and designed and the clearance limit surfaces of each area to check whether the layout of the photovoltaic panel module to be planned and designed exceeds the height limit or has redundant height.

[0035] In this embodiment, the Civil 3D software "_MinimumDistBetweenSurfaces" is invoked, and the "Minimum Distance Between Surfaces" command is selected from the menu bar. The software calculates the minimum distance between surfaces automatically. If the minimum distance between surfaces is negative, it is considered superheight; if the minimum distance between surfaces is positive, it is considered redundant height.
