[0002] Urban planning requires a large amount of urban planning results, basic data and social and economic development data indicators. Planners often face the practical problem of "lack of basic data" in their actual work, which restricts the efficient, accurate, scientific and reasonable development of planning work; at the same time, urban planning is a comprehensive and systematic work, involving multiple industries and fields, and requires a lot of data calculation and analysis. Planners often face the problem of lack of convenient and professional analysis tools, which makes it difficult to complete special plans on schedule; urban business market information is mixed and scattered, market investment and marketing personnel lack systematic cognition of market information, and lack scientific judgment on the reliability and timeliness of information, resulting in a lack of purposefulness in market work and market personnel are often exhausted.

[0003] Traditional urban planning mainly relies on manpower, data processing is mostly done offline, and relies heavily on personal experience and intuition, which often makes work inefficient. Summary of the invention

[0004] The present invention aims to solve the problems faced by urban planning business, such as "lack of basic planning data", "backward planning calculation tools" and "lack of high-end think tanks serving the market", and creates an online interactive digital urban planning system for urban planning and market analysis through digital technology.

[0005] The present invention is implemented by the following technical solutions:

[0006] An online interactive digital urban planning system, including four core modules: project information management, project planning compliance assessment, project economic feasibility assessment and project construction plan output, among which:

[0007] The project information management module is used to search, add, edit, delete, define scope and spatially locate projects;

[0008] The project planning compliance assessment module includes two major functions: project planning compliance assessment and project surrounding and current situation assessment. Among them: project planning compliance assessment is used to determine whether the project planning location meets the construction requirements of the three zones and three lines, and whether the project industrial use meets the land use and indicator construction requirements of the master plan or control plan;

[0009] The project economic feasibility assessment module constructs economic calculation and assessment model parameters. The system backend uses preset formulas to calculate the economic calculation and assessment model parameters and generates the project economic feasibility assessment results.

[0010] The project construction plan output module outputs the project construction plan by importing the project construction plan template, selecting the template to insert content, and exporting the plan results. After analysis and evaluation by the project planning compliance assessment module and the project economic feasibility assessment module, the project construction plan is analyzed and evaluated.

[0011] Preferably, the project information management module includes:

[0012] Project search operation: filter out projects that meet the search criteria; when searching for projects, filter based on project name, location, and project planned use type, among which project planned uses include industrial parks, residential areas, commercial areas, and office buildings.

[0013] Add project information: When adding a new project, edit and enter the detailed data of the project and determine the project scope. There are two ways to confirm the project scope: one is to directly locate and draw the project boundary line on the map component; the other is to upload the spatial vector data shp file of the project. The system background will parse the file and record the spatial scope of the project. After completing the above operations, save the project information record, and you can quickly locate its spatial scope on the map by clicking the project name.

[0014] Modify project information: If you need to update the project information, you can edit and modify the project information and save the changed project information record.

[0015] Delete project information: This operation will completely clear all relevant information records of the project.

[0016] Preferably, the process of determining whether the project planning location meets the construction requirements of the three zones and three lines includes:

[0017] First, by using Internet search engines or artificial intelligence large-scale model technology, retrieve and obtain the three-zone and three-line boundary data of the project area; use the geographic information system map component to accurately locate the specific location of the project, and overlay the three-zone and three-line boundary layer data of the project area;

[0018] Then, through computational geometry algorithms, the spatial relationships between the project vector surface and the three zones and three lines vector surface, such as intersection, inclusion, and separation, are accurately determined; for intersection and inclusion, the geometric properties of the area and perimeter of the intersection are further analyzed, and the impact of the project on the three zones and three lines is evaluated in combination with relevant planning rules and indicators. During the analysis process, the system considers the impact of terrain and geomorphic factors on spatial relationships, and analyzes the terrain undulations of the project area and its relative position relationship with the three zones and three lines through digital elevation model data.

[0019] Preferably, the process of determining whether the industrial use of the project complies with the land use and construction index requirements of the master plan or control plan includes:

Combined with the project planning use type, the system determines whether the project's industrial use complies with the master plan or control plan land use and indicator construction requirements.

[0021] Preferably, the project surrounding and current status assessment includes:

[0022] ①. Determine the location of the project, clarify whether the project is in the urban area, suburban area or suburbs, and explain in detail the advantages and disadvantages of the project's location, such as the commercial prosperity of the urban area, the convenience of transportation hubs, the richness of land resources and the ecological environment advantages of the suburbs.

[0023] ②. Determine the surrounding traffic conditions, analyze the traffic routes and road conditions around the project, and the convenience of connection with major transportation hubs, and give a comprehensive evaluation of traffic convenience.

[0024] ③. Determine the overall layout of surrounding competing products, count the number, type, scale and distribution density of competing products, and analyze the competitive advantages and disadvantages of competing products.

[0025] Preferably, the process of determining the location of the project includes: ①, retrieving the location data of the project area by using an Internet search engine or advanced artificial intelligence large-scale model technology; ②, accurately locating the specific location of the project with the help of a geographic information system map component, and superimposing the location boundary layer data of the project area; ③, calculating the spatial topological analysis relationship between the two. When performing spatial structure topological analysis, the imported vector data is first preprocessed; the preprocessing includes geometric correction of the data, topological checking and coordinate system conversion; ④, outputting the analysis results of whether it is located in an urban area, suburban area or suburb on the analysis panel.

[0026] Preferably, the web crawler technology is used to crawl Internet map data. The web crawler first performs an initial detection on the target website, analyzes the directory structure and data storage method of the website, and builds an initial crawling path list. Then, during the crawling process, intelligent recognition of verification codes, dynamic IP switching, and dynamic adjustment of crawling rules are used, and multi-threading technology is used to crawl data from multiple pages at the same time.

[0027] Preferably, a spatial topology analysis algorithm is used to accurately identify and quantitatively display the traffic and competitor POIs located in the project buffer zone, and the implementation steps include: setting a reasonable buffer zone radius; constructing a circular area as the analysis range by extending the specified buffer radius around the project location as the center; traversing the traffic and competitor POI data sets that have been acquired and completed the coordinate conversion; screening out all POI points located in the circular area; classifying in detail according to the category of POI, and summarizing the number of POIs of each category; and intuitively displaying the analysis results in the form of charts.

[0028] Preferably, the input of the economic calculation and evaluation model is the basic information and market data of the project; the output is the calculation results of the economic feasibility of the project, including project cost calculation, project benefit calculation, and analysis and comparison parameters of various benefit indicators with national recommended reference materials.

[0033] S44. Based on the calculation results of various parameters of the comprehensive project economic feasibility assessment module, the expected cost of the project, project revenue and revenue index analysis results are obtained.

[0034] Compared with the prior art, the present invention has the following advantages and effects:

[0035] 1. Improvement of data collection efficiency: With the help of web crawler technology, the required data can be quickly captured from the Internet. This method significantly speeds up the collection and processing of data. The web crawler technology of this system has unique advantages in data collection. It adopts advanced adaptive crawling strategies, which can dynamically adjust crawling rules according to the structure and data update frequency of different websites. For example, for the official websites of some government planning departments, their data updates are relatively regular and the format is relatively standardized. The crawler will crawl efficiently according to the predetermined schedule and specific HTML tag parsing rules to ensure that the latest urban planning results, basic data and social and economic development data indicators and other information are obtained.

[0036] 2. Extensive collection of data resources: Using AI big model technology for question-and-answer interaction can reach more diverse data sources, thereby collecting richer and more comprehensive data information. When using AI big model technology for data collection, the system first builds a knowledge graph specifically for the field of urban planning. This knowledge graph integrates a large number of concepts, entities, and relationships related to urban planning as the background knowledge of the AI ​​big model. When data needs to be collected, the system inputs the user's query requirements or specific task instructions into the AI ​​big model. The model performs semantic understanding and reasoning based on the knowledge graph and generates a series of possible data source search strategies. For example, when it is necessary to understand the industrial planning data of a certain area, the AI ​​big model will guide the system to search from multiple channels based on the relationship between industrial planning and relevant government departments, research institutions, corporate reports, etc. in the knowledge graph, including the website of the economic development department of the local government, the database of professional industrial research institutions, and the annual reports of well-known companies in the industry. At the same time, the AI ​​big model can also perform preliminary screening and sorting of the collected data, remove some obviously irrelevant or low-quality information, and ensure the validity and reliability of the data.

[0037] 3. Enhancement of data visualization and spatial analysis: By integrating GIS technology and visualization methods, data can be displayed on the map in a clear and intuitive way, and in-depth spatial structure topological analysis can be performed, which significantly improves the quality of data visualization and the level of spatial analysis. When performing spatial structure topological analysis, GIS technology first preprocesses the imported vector data. This includes operations such as geometric correction of data, topological checking, and coordinate system conversion to ensure the accuracy and consistency of the data. Taking the spatial topological analysis of the project planning location and the three zones and three lines as an example, the system uses GIS's spatial analysis tools to superimpose the project's vector data with the vector layer of the three zones and three lines. Then, through computational geometry algorithms, the spatial relationships such as intersection, inclusion, and separation between the project vector surface and the three zones and three lines vector surface are accurately determined. For intersection and inclusion, the geometric properties such as the area and perimeter of the intersecting part are further analyzed, and the impact of the project on the three zones and three lines is evaluated in combination with relevant planning rules and indicators. During the analysis process, the system will also consider the impact of geographical factors such as terrain and landforms on spatial relationships. Through digital elevation model (DEM) data, it will analyze the terrain undulations of the project area and its relative position to the three zones and three lines, providing more comprehensive information for planning decisions.

[0038] 4. Convenient analysis of project economic feasibility: The system has developed an Excel model containing a variety of preset calculation formulas for project economic calculations, which can quickly derive key indicators of the project's economic feasibility.

[0048] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0049] The present invention is based on digital technologies such as big data, search engines, machine learning, and digital twins to support urban planning in industrial planning, park planning, urban renewal, carbon emission assessment, park comprehensive energy planning, urban river and lake water system connectivity and other planning business work, and uses big data and visualization technology to support urbanization business market work, and fully serve the early planning and market development of urbanization business. By conducting research and development on data resources, planning analysis tools, information consulting services, and visualization displays around urban planning business, an urban planning big data platform is tailored for urbanization business to improve the digital technology level of urban planning business.

[0050] The present invention uses web crawlers and AI big model technology to efficiently collect a large amount of vector data related to project planning from the Internet. Through the application of GIS (geographic information system) and digital twin visualization technology, these data are integrated into the map level, thereby achieving clear presentation of data and in-depth spatial topological analysis, and then obtaining the conformity assessment results of the project planning. Then, using the economic calculation model template, the key indicators of the economic feasibility of the project are calculated. Finally, the conformity assessment results of the project planning are combined with the economic feasibility results to develop a reasonable and feasible project construction plan.

[0051] In order to overcome the drawbacks of low efficiency caused by manual operation, offline processing and over-reliance on experience in traditional urban planning, the present invention provides an online interactive digital urban planning system. The system can provide scientific and efficient technical support for the planning and evaluation of urban planning projects, bringing obvious economic and social benefits. Figure 1 As shown, the entire system covers four core modules: project information management, project planning compliance assessment, project economic feasibility assessment, and output of project construction plans.

[0052] 1. Project information management module: Figure 2 The project information management module is implemented through the project information component, which is used to search, add, edit, delete, scope and spatially locate projects. Specifically:

[0053] Project search operation: filter out projects that meet the search criteria. When searching for projects, you can filter by project name, location, and project planning use type. Among them, the project planning use types are diverse, including industrial parks, residential areas, commercial areas, and office buildings.

[0054] Add project information: When adding a new project, you need to edit and enter the detailed data of the project and determine the project scope. There are two ways to confirm the project scope: one is to directly locate and draw the project boundary line on the map component; the other is to upload the spatial vector data shp file of the project. The system background will parse the file and record the spatial scope of the project. After completing the above operations, save the project information record, and you can quickly locate its spatial scope on the map by clicking the project name.

[0055] Modify project information: If you need to update the project information, you can edit and modify the project information and save the changed project information record.

[0056] Delete project information: This operation will completely clear all relevant information records of the project.

[0057] 2. Project planning compliance assessment module: Figure 3 This module includes two functions: project planning compliance assessment and project surrounding and current status assessment. Among them:

[0058] 1) Project planning compliance assessment is used to determine whether the project planning location meets the construction requirements of the three zones and three lines, and whether the project industrial use meets the land use and indicator construction requirements of the master plan or control plan. Including:

[0059] By using Internet search engines or advanced artificial intelligence large-scale model technology, retrieve and obtain the three-zone and three-line boundary data of the project area. Figure 4 , use the geographic information system (GIS) map component to accurately locate the specific location of the project, and overlay the three-zone and three-line boundary layer data of the project area. Then, through computational geometry algorithms, accurately determine the spatial relationship between the project vector surface and the three-zone and three-line vector surfaces, such as intersection, inclusion, and separation. For intersection and inclusion, further analyze the geometric properties such as the area and perimeter of the intersecting part, and combine relevant planning rules and indicators to evaluate the impact of the project on the three zones and three lines. During the analysis process, the system will also consider the impact of geographical factors such as topography and landforms on spatial relationships. Through digital elevation model (DEM) data, analyze the terrain undulations in the project area and the relative position relationship with the three zones and three lines, providing more comprehensive information for planning decisions.

[0060] Similarly, by using Internet search engines or advanced artificial intelligence large-scale model technology to retrieve the master plan or control plan land use and indicator construction requirements for the project area, combined with the project planning use type, the system can easily determine whether the project's industrial use complies with the master plan or control plan land use and indicator construction requirements.

[0061] 2) Project surrounding and current status assessment includes:

[0062] ①. Determine the location of the project. The result should clearly state whether the project is located in the urban area, suburban area or suburbs, and explain in detail the advantages and disadvantages of the project location, such as the commercial prosperity of the urban area, the convenience of transportation hubs, the richness of land resources, and the ecological environment advantages of the suburbs.

[0063] ②. To judge the surrounding traffic conditions, it is necessary to analyze the traffic routes around the project (such as the coverage of bus routes, subway lines and the distance between stations), road conditions (road grade, traffic capacity, congestion), and the convenience of connection with major transportation hubs (airports, railway stations, bus stations, etc.), and give a comprehensive evaluation of traffic convenience.

[0064] ③. To judge the overall layout of surrounding competing products, it is necessary to count the number, type (such as residential, commercial, office buildings, etc.), scale (land area, building area) and distribution density of competing products, and at the same time analyze the competitive advantages (such as the completeness of supporting facilities, brand influence) and disadvantages (such as price positioning, apartment design) of competing products to provide a reference basis for the planning and positioning of the project.

[0065] Specifically:

[0066] By using Internet search engines or advanced artificial intelligence large-scale modeling technology, retrieve and obtain the location data of the project area. Figure 5 First, the specific location of the project is accurately located with the help of the Geographic Information System (GIS) map component, and the location boundary layer data of the project area is superimposed. Then, the spatial topological analysis relationship between the two is calculated. When performing spatial structure topological analysis, GIS technology first pre-processes the imported vector data. Pre-processing includes operations such as geometric correction of data, topological checking, and coordinate system conversion to ensure the accuracy and consistency of the data. Finally, the analysis results are output on the analysis panel so that the system can determine whether it is located in an urban area, suburban area, or suburban area.

[0067] In the implementation process, web crawler technology is used to crawl Internet map data. The web crawler will first perform an initial detection of the target website, analyze the directory structure and data storage method of the website, and build an initial crawling path list. Then, during the crawling process, multi-threading technology is used to extract data from multiple pages at the same time, which greatly improves the crawling speed. Compared with traditional web crawler technology, the crawler of this system can better cope with changes in website structure and anti-crawling mechanisms, and ensure the stability and continuity of data crawling through intelligent recognition of verification codes, dynamic IP switching and other means.

[0068] Obtain traffic POI data around the project and surrounding competitor POI data. Traffic POI data includes POI data of bus stops, bus stations, subway entrances, railway stations, airports, etc., while competitor POI data includes POI data of industrial parks, residential, commercial, office buildings, etc. Then use GIS data processing tools to convert the POI data coordinate system and present it on the map. Set the buffer range conditions, analyze the road traffic conditions around the project, and the system automatically judges and summarizes the traffic accessibility analysis results.

[0069] In a preferred embodiment, a spatial topology analysis algorithm is used to accurately identify and quantitatively display the traffic and competitive POIs located in the project buffer zone. Figure 6 The implementation steps include: setting a reasonable buffer radius; constructing a circular area with the project location as the center and extending the specified buffer radius to the surrounding areas as the analysis scope; traversing the traffic and competitor POI data sets that have been acquired and completed coordinate transformation; screening out all POI points within the above circular area; classifying POIs in detail according to their categories, and summarizing the number of POIs of each category; and visually displaying the analysis results in the form of charts, such as Figure 7 Example.

[0070] Click on the POI icon of nearby competitors, and use the Internet search engine or advanced artificial intelligence large-scale model technology to search for the competitor's name to obtain data such as the competitor's construction time, development theme, land use nature and scale, product category and scale, pricing and sales speed, number of settled companies, and economic benefits of settled companies, and display it in a pop-up window.

[0071] 3) Based on the above conditions, planners can choose to output the project planning compliance assessment results.

[0072] 3. Project economic feasibility assessment module: Figure 8 , construct economic calculation and evaluation model parameters, and the background uses preset formulas to calculate these parameters to generate project economic feasibility calculation results.

[0073] The inputs to the economic calculation and evaluation model include basic information about the project, such as project type (such as hotels, commercial centers, industrial parks, etc.), project scale (land area, building area, etc.), project location (geographic location information, used to consider factors such as land costs and market environment), and related planning parameters (such as parameters related to the expected benefits of the planned use). In addition, it also includes acquired market data, such as land price trends, operating costs and revenue data of similar projects, etc.

[0074] The output of the economic calculation and evaluation model is the calculation result of the economic feasibility of the project, including parameters such as project cost calculation, project income calculation, and analysis and comparison of various income indicators with national recommended reference materials. In terms of implementation, the model is calculated based on pre-set calculation formulas and algorithm libraries. For example, for project cost calculation, land costs are calculated based on the land market price of the project location and the project area; engineering costs are estimated based on the construction scale and building type of the project, with reference to the cost standards and empirical data of the construction industry. Project income calculation adopts corresponding income prediction models according to the characteristics of different planning types of projects. For example, for hotel type planning projects, the hotel occupancy rate is obtained by analyzing and predicting the local tourism market, business activity level, and occupancy of hotels of the same grade. The house price increase is estimated in combination with market trends and economic development expectations. The proportion of supporting facilities income is determined based on the type and scale of the hotel's supporting facilities and with reference to the industry average level. During the calculation process, the model will also consider the impact of economic factors such as inflation and interest rates. By introducing the economic indicator prediction model, the economic environment in the future period is simulated and analyzed to ensure the accuracy and reliability of the calculation results.

[0075] Specifically, Fig. 9 , for project cost estimation, including land costs, engineering costs, other engineering construction costs, unforeseen expenses, operating expenses, value-added tax and surcharges, land use tax, property tax, corporate income tax, decoration costs and other aspects of cost estimation.

[0076] For project revenue estimation, according to different planning types of projects, enter the revenue estimation items of their planning types, such as hotel type planning projects, including hotel occupancy rate, hotel rooms, room rate increase, supporting facilities revenue ratio, etc.;

[0077] The analysis and comparison of various income indicators with national recommended reference materials include the project's after-tax net profit, project net profit margin, total investment internal rate of return, annual operating income, project dynamic investment payback period, project investment financial net present value, project investment financial internal rate of return, etc.

[0078] Specifically: The input of the basic economic calculation model mainly comes from the project planning and market data. Specifically, it includes the project's investment budget information, such as land acquisition costs, construction capital investment plans, etc.; the project's operating cost estimation data, such as labor costs, material procurement costs, equipment maintenance costs, etc.; and market demand and price forecast data, such as the expected sales price of products or services, the forecast value of market demand, etc. The output is the result of the basic economic calculation model, including calculation assumptions, total project investment, related planned commercial use schedules, cost and profit forecast tables, cash flow statements, etc.

[0079] During the implementation process, the estimation assumptions are set according to the background and market environment of the project, such as the key parameters such as the construction period, operating life, and market growth rate of the project. The total investment of the project is calculated by summarizing the investment budget data. The relevant planned commercial use schedule plans and arranges the layout and scale of different commercial formats according to the planned use and market positioning of the project. The cost-profit forecast table is based on the cost data and revenue forecast data of the project, and is calculated and summarized in time series to show the cost and profit of the project in different time periods. The cash flow statement records and analyzes the cash inflows and outflows of the project in detail, calculates important financial indicators such as the net cash flow, internal rate of return, and net present value of the project, and provides a comprehensive basis for the economic feasibility assessment of the project.

[0080] 4. Project construction plan output module: This module is implemented through the plan component function, and has the functions of importing project construction plan templates, selecting templates to insert content, and exporting plan results. After the project planning compliance assessment module and the project economic feasibility assessment module analyze the assessment results, the project construction plan is output, including project positioning, project scale, project spatial layout, project economic feasibility calculation results, etc.

[0081] S41. Determine the project positioning planning use type option based on the evaluation results of the project planning compliance evaluation module.

[0082] S42. Based on the evaluation results of the project planning compliance evaluation module and the project economic feasibility evaluation module, determine the scale of the project that can be built.

[0083] S43. Based on the assessment results of the project planning compliance assessment module and taking into account the geographical location, design a suitable project spatial layout.

[0084] S44. Based on the calculation results of various parameters of the comprehensive project economic feasibility assessment module, the expected cost of the project, project revenue and revenue index analysis results are obtained.

[0085] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
