Description

Technical Field

[0001] This invention belongs to the field of landscape design technology for garden plants, specifically a method for airflow analysis and configuration of landscape plants based on LIM technology. Background Technology

[0002] In the design process of garden plant landscapes, the industry applies LIM (Limited Information Modeling) technology, but the following situations have arisen: For garden plant landscape design, landscape designers often present renderings based on their own idealized vision of the plants, largely neglecting the impact of growth constraints. This is partly due to the limited experience of landscape designers, who, faced with new planting scenarios, cannot accurately predict airflow, leading to incorrect selection of plant species and sizes. Furthermore, during the construction phase of the garden plant landscape, the layout of various surrounding buildings and facilities alters airflow, creating a funnel effect, concentrating airflow, and resulting in a complex wind environment. Strong winds reduce plant transpiration and break newly sprouted leaves, leading to poor growth in many trees. Wind also damages the wax layer of leaves, causing dwarfing and reduced crown size.

[0003] Furthermore, airflow issues also affect plant landscapes in several ways: after the plant landscape is completed, some areas may experience rapid localized temperature changes due to cold northwest winds; extensive investigations and comparisons have shown that the windward side of the plant landscape cools down faster and is colder, increasing the likelihood of plants freezing to death. Therefore, airflow issues consistently contribute to the death or poor growth of some plants in new environments, severely impacting the final effect of the completed plant landscape.

[0004] In existing technologies, to compensate for or remedy the effects of plant landscapes, the common approach is to continuously replace plants during the construction or maintenance phases to improve the landscape, resulting in significant waste. Therefore, how to incorporate and address airflow issues during the design and configuration phases of landscape architecture plants to reduce unnecessary later investment of effort has become a research focus for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background technology by introducing and paying attention to airflow issues in the design and configuration stage of landscape plants, so as to maximize the effect of landscape plants. This invention, through methods such as wind environment and airflow analysis of plant sites, and with the assistance of LIM technology, enables landscape designers to make precise selections of plant species and specifications, so that plants can achieve the expected effect in new scenes without having to spend a lot of energy on later maintenance.

[0006] The present invention employs the following technical solutions to achieve its objective:

[0007] A method for airflow analysis and configuration of landscape plants based on LIM technology, the method comprising the following steps:

[0008] S1. Measure and obtain airflow data for the target scene;

[0009] S2. Establish a scene model corresponding to the target scene and import the scene model containing airflow data into the analysis software;

[0010] S3. Based on the airflow data, the wind environment analysis results corresponding to the target scene are obtained through the wind environment analysis plugin of the analysis software;

[0011] S4. Obtain plant survival attribute data. Based on the plant survival attribute data and wind environment analysis results, select and match the plant species and plant specifications of each plot in the scene model to realize the complete establishment of the landscape plant model.

[0012] S5. Render the landscape model of the garden plants, continuously optimize and complete the final selection and matching scheme of plant species and specifications during the rendering process.

[0013] Specifically, in step S1, the target scene is the actual location where the landscape garden plant landscape is prepared and configured; multiple wind force measurement points are set up in the target scene, and wind speed, wind direction and temperature data are collected at each wind force measurement point through a meteorological data collector, and the data are summarized to form airflow data.

[0014] Preferably, wind speed, wind direction, and temperature data of the target scene over a one-year period are collected as annual measurement data, which are then organized and summarized to form annual airflow data. This annual airflow data serves as the basis for simulation data in the wind environment analysis process of the scene model.

[0015] Furthermore, in step S2, the scene model includes a site model and building and hardscape models; after the site model is imported into the analysis software, a full-area analysis grid is established, and the airflow data corresponding to each full-area analysis grid of the site model is loaded.

[0016] Specifically, the process of creating the scene model involves using the landscape design topographic map presented in the CAD software. After data preprocessing, the data is linked to the Revit modeling software to create the scene model. Then, the Revit modeling software's export tool is used to export the created scene model as a model file, which is then imported into the Ecotect Analysis software.

[0017] Specifically, in step S3, after the model file is imported into the Ecotect Analysis software, a full-area analysis grid corresponding to the site model is created; then, the size of the full-area analysis grid is adjusted using the grid analysis tool of the Ecotect Analysis software so that the full-area analysis grid covers the entire surface of the site model.

[0018] Specifically, after the full-area analysis grid is adjusted, the WinAir4 program of Ecotect Analysis software is used as a wind environment analysis plugin to analyze the airflow data corresponding to each grid in the full area, calculate the preliminary analysis results, and generate the corresponding analysis files.

[0019] Preferably, the analysis file is re-input into Ecotect Analysis software, and the grid analysis tool is used again to present the values ​​and analysis images of the elevation plane, wind speed and wind direction of the entire scene model under different grid areas, which vary with the terrain undulation and the layout of buildings and hardscape. The corresponding values ​​and analysis images are summarized to obtain the wind environment analysis results corresponding to the target scene.

[0020] Specifically, in step S4, the landscape designer obtains plant survival attribute data, compares the plant survival attribute data with the wind environment analysis results, selects and matches suitable plant species for the corresponding plot, determines the plant specifications, and completes the preliminary design of the landscape scheme.

[0021] Preferably, after the preliminary design of the landscape scheme is completed, Revit modeling software is used to create plant models based on plant species and configuration points. After the scene model and plant model are completed, the software view mode is switched to a 3D view, and the Lumion rendering software is opened through the Lumion launcher in the Revit modeling software to proceed to step S5. In step S5, under the viewport of the Revit modeling software or Lumion rendering software, the landscape designer continues to optimize the selection and matching scheme of plant species and plant specifications based on the data foundation of the rendering effect changes presented by the viewport linkage and the wind environment analysis results, forming the final landscape design scheme, which is then delivered to the construction unit to complete the landscape construction process and obtain the finished landscape.

[0022] In summary, due to the adoption of this technical solution, the beneficial effects of this invention are as follows:

[0023] The method of this invention focuses on airflow issues in the design, analysis and configuration of landscape plant landscapes; in the design stage, it is based on the annual airflow data of the corresponding target scene, so the influence of airflow on the plants in spring, summer, autumn and winter is fully considered, which can maximize the realization of the effect of landscape plant landscape.

[0024] When this method is applied to the design and configuration process, it can not only meet the three-dimensional visualization needs of all parties involved in the construction for the landscape effect, but also effectively ensure that landscape designers can accurately select plant species and specifications with the assistance of airflow data. It can effectively solve the problem of increased construction costs caused by the difficulty in survival and poor growth of some plants affected by airflow, and is more conducive to the better growth of plants in new scenarios to achieve the expected results. It can effectively reduce the construction costs of the construction party and the maintenance costs of the operators for garden plants. Attached Figure Description

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] Example

[0029] A method for airflow analysis and configuration of landscape plants based on LIM technology. The overall process of this method can be found in [reference needed]. Figure 1 The summary includes the following steps:

[0030] S1. Measure and obtain airflow data for the target scene;

[0031] S2. Establish a scene model corresponding to the target scene and import the scene model containing airflow data into the analysis software;

[0032] S3. Based on the airflow data, the wind environment analysis results corresponding to the target scene are obtained through the wind environment analysis plugin of the analysis software;

[0033] S4. Obtain plant survival attribute data. Based on the plant survival attribute data and wind environment analysis results, select and match the plant species and plant specifications of each plot in the scene model to realize the complete establishment of the landscape plant model.

[0034] S5. Render the landscape model of the garden plants, continuously optimize and complete the final selection and matching scheme of plant species and specifications during the rendering process.

[0035] The above five steps are the main and key steps of this method. The following is a detailed description of them in this embodiment. The order of the description follows the logical sequence of the steps, and the optimal method is also given.

[0036] First, airflow data for the target scene is measured and obtained. The target scene is the actual location of the landscape garden plant landscape to be configured. In this embodiment, multiple wind measurement points are set up in the target scene. The selection of points should be representative. At each wind measurement point, wind speed, wind direction and temperature data of the target scene within a year are collected using an FT-QC9H model meteorological data logger. These are used as annual measurement data, which are then organized and summarized to form annual airflow data. The annual airflow data is used as the simulation data basis in the wind environment analysis process of the scene model.

[0037] Next, proceed to step S2, where the scene model includes a site model and building and hardscape models. The site model is created as follows: open the landscape design topographic map in CAD software, perform data preprocessing, delete points, lines, and redundant markers that do not contain elevation information, and retain only graphic elements that completely and accurately describe the terrain structure in three dimensions; then link the preprocessed landscape design topographic map to Revit modeling software, and use the software's built-in site modeling tools to generate a three-dimensional landscape topographic model, thus creating the site model; the building and hardscape models are also created directly in Revit modeling software, forming the entire scene model.

[0038] After summarizing the scenario model and corresponding airflow data, export it as a ".dxf" format model file, and then import the model file into the Ecotect Analysis software.

[0039] In step S3, after the model file is imported into the Ecotect Analysis software, a full-area analysis grid corresponding to the site model is created. In this embodiment, based on the actual size of the scene model, the size of the full-area analysis grid is adjusted using the grid analysis tool of the Ecotect Analysis software so that the full-area analysis grid covers the entire surface area of ​​the site model.

[0040] Following the completion of the full-area analysis grid adjustment, the WinAir4 program of the Ecotect Analysis software was used as a wind environment analysis plugin. WinAir4 itself is an extension plugin for the Ecotect Analysis software, and this extension plugin needs to be pre-installed on the corresponding analysis computer. Using the "Output Model Data" function of the WinAir4 program, the annual airflow data corresponding to the scene model was input into the Ecotect Analysis software. After starting the analysis command, the WinAir4 program automatically calculated and analyzed the preliminary analysis results of the corresponding terrain within the grid area, generating an analysis file in ".goe" format and an "OUTPUT" file.

[0041] The obtained analysis file is then input into the Ecotect Analysis software. Through the grid analysis tool, the numerical and analytical images of the elevation plane, wind speed, and wind direction of the entire scene model under different grid areas are presented as they change with the terrain undulations and the layout of buildings and hardscape. The corresponding numerical and analytical images are then summarized to obtain the wind environment analysis results corresponding to the target scene.

[0042] After obtaining the wind environment analysis results, step S4 is performed, simultaneously establishing a plant model and other related processes during the plant configuration process. In this embodiment, the landscape designer obtains plant survival attribute data, compares this data with the wind environment analysis results, and accurately selects and matches plant species and specifications based on wind speed, wind pressure, temperature, and other data for each location, as well as the growth attributes and characteristics of the plants. This allows for a scientific and reasonable design of the combination of garden plants and the landscape, while simultaneously determining plant specifications and completing the preliminary design of the landscape scheme.

[0043] Regarding the creation, rendering, and application of plant models, this embodiment provides the following optimal supplementary explanation. Using Revit modeling software, based on the preliminary design of plant species and placement points, plant models are created. These plant models utilize concept families instead of actual plant models. Within the plant model concept family, ellipsoids and cylinders are combined to form plant shapes. Plant species are distinguished by model color, and plant sizes are differentiated by model size, thus completing the creation of the selected and configured plant models. Modeling plant models using concept families avoids Revit modeling software lag or crashes caused by excessively large model sizes, reducing design costs while ensuring the successful completion of the plant models required for the design drawings.

[0044] In step S5, the entire landscape plant model includes plant models, site models, and building and hardscape models. After modeling is completed, the Revit software view mode is switched to a 3D view, and the Lumion rendering software is opened through the Lumion plugin in the Revit modeling software. After all models in the Revit modeling software are imported into the Lumion rendering software through the plugin, viewport linkage between the Revit modeling software and the Lumion rendering software can be achieved. Landscape designers can continue to optimize the selection and combination of plant species and specifications based on the viewport linkage in either the Revit modeling software or the Lumion rendering software. Thanks to the excellent linkage between the Revit modeling software and the Lumion rendering software, Revit model files are automatically imported into the Lumion software. After the two software programs achieve viewport linkage, modifications to the model or adjustments to the viewport in either software will be synchronized in the other software, greatly improving the user experience and efficiency of the scheme optimization process.

[0045] In this embodiment, with the viewports linked between Revit modeling software and Lumion rendering software, the material selection and assignment operations for the site model, building, and hardscape model are completed in Lumion rendering software based on the real 3D data information in Revit modeling software. At the same time, based on the plant species and configuration points of the plant family form in Revit modeling software, the corresponding matching real plant model is selected from the plant library in Lumion rendering software to replace the conceptual family model. During the material assignment and model replacement process, the landscape designer continues to optimize the selection and matching scheme of plant species and plant specifications, adjusts and modifies the landscape, and obtains the landscape design scheme after optimization.

[0046] At this point, the entire landscape design scheme is formed and presented in Revit modeling software. Using the drawing tools in Revit, the corresponding landscape CAD design drawings are output. Using Lumion rendering software, corresponding rendering image files are output, including landscape renderings and videos. The landscape CAD design drawings and rendering image files are then delivered to the construction unit. Based on the landscape CAD design drawings and rendering image files, the construction unit completes the construction process of the landscape design scheme, resulting in the finished landscape. With the help of the landscape CAD design drawings and rendering image files, the construction unit can accurately understand the design intent and complete the construction tasks of the landscape scheme precisely and efficiently.

[0047] In summary, the method of this embodiment introduces airflow analysis into the landscape design and configuration process of plants under LIM technology to solve the impact of airflow on plants. Therefore, this method eliminates the airflow problems that plants may encounter in the new scene when designing and configuring the landscape. After the landscape construction is completed, it can greatly avoid the occurrence of poor plant growth and death, thereby saving later maintenance and replacement costs and reducing unnecessary effort.
