Description

Technical Field

[0001] The present invention belongs to the technical field of wind farm reconnaissance, and specifically relates to a multi-terminal interconnected wind farm reconnaissance and site selection method based on 3D and GIS technologies. Background Art

[0002] In the construction of wind farms, reconnaissance and site selection is a crucial preliminary task, and its accuracy and efficiency directly affect the implementation effect and economic benefits of wind power projects. The existing wind farm reconnaissance technologies mainly rely on on-site surveys, using devices such as GPS locators and cameras to comprehensively evaluate the location, road conditions, natural environment, etc. of the wind farm. During the survey process, the actual data collected by on-site personnel, including information such as the layout of wind power equipment and the feasibility analysis of the wind farm, is further analyzed to determine the feasibility of the construction of the wind power project, so as to ensure the smooth progress of the wind farm construction and maximize the power generation efficiency.

[0003] However, in actual operation, there are some significant problems with traditional reconnaissance methods. First, the number of reconnaissance points is large, and limited by the on-site environment, there are certain difficulties in uploading and archiving picture data. The survey personnel may not be able to upload on-site pictures in a timely manner, and due to the large amount of data, the path records and picture data during the uploading process may be delayed, resulting in low efficiency and accuracy in archiving and recording. Second, especially during the archiving process, due to the large number of pictures and point records, there are efficiency problems in the integration and storage of information, seriously affecting the accuracy of the data and the convenience of subsequent processing. In addition, the reconnaissance data cannot be uniformly managed after being sorted out, resulting in fragmented and scattered storage of data, making it difficult to efficiently integrate and manage.

[0004] To solve the above problems, the present invention proposes a multi-terminal interconnected wind farm reconnaissance and site selection method based on 3D modeling and GIS (Geographic Information System) technologies. This method utilizes modern information technologies to achieve efficient data management, real-time synchronization, and intelligent decision-making support during the wind farm reconnaissance process, improving the accuracy, convenience, and overall efficiency of the reconnaissance. Through the multi-terminal interconnected platform, the present invention can generate a digital model of the wind farm in real time on-site, and combine with GIS technology to achieve real-time data collection, synchronous uploading, and automatic archiving. In addition, by introducing 3D modeling technology, the present invention can more intuitively display the topography and surrounding environment of the wind farm, helping users make more accurate site selection decisions. The multi-terminal interconnected platform ensures the centralized management of data, solves the problems of scattered data and difficult integration in traditional solutions, and realizes unified storage and standardized management, greatly improving the availability and security of the data.

[0005] In summary, by introducing 3D modeling and GIS technologies and combining with a multi-terminal interconnection platform, the present invention effectively solves the problems of the existing wind farm site investigation and selection methods in aspects such as data management, real-time synchronization, data display, and archive management, providing strong technical support for the implementation of wind farm projects. Summary of the Invention

[0006] Aiming at the technical problems of difficult data upload and archiving, low information integration and storage efficiency, and decentralized data management existing in the existing wind farm site investigation technologies, the present invention adopts the following technical solutions.

[0007] The present invention provides a multi-terminal interconnected wind farm site investigation and selection method based on 3D modeling and GIS technologies. The method realizes real-time data collection, synchronous upload, and automatic archiving by introducing 3D modeling technology and GIS technology. Further, the method relies on a multi-terminal interconnection platform to support the access and operation of the computer terminal and the mobile terminal, ensuring that users can view, edit, and manage project information anytime and anywhere. Among them, the method includes multiple steps to achieve a complete site investigation process.

[0008] S1 Project creation and configuration. Users create a new wind farm site investigation project or update an existing project on the platform. The platform provides a variety of operation tools, and users can add and modify various elements in the project according to actual needs. These elements include the layout of wind turbines, metrological towers, booster stations, road paths, site investigation trajectories, and field areas, which are used to depict the topography and potential construction locations of the wind farm in detail.

[0009] S2 Data synchronization and real-time update. During the site investigation process, all operations, whether on the computer terminal or the mobile terminal, can be synchronized to the database in real time. The database ensures that all project members can see the latest project information, avoiding problems of data lag and information inconsistency.

[0010] S3 Site investigation plan and information recording. When users create a new site investigation plan, a complete site investigation plan is formed by adding new elements such as points, lines, and surfaces based on the basic information of the existing project. The detailed information of each site investigation point includes name, description, and longitude and latitude, and pictures or video materials taken on-site can be attached.

[0011] S4 3D display and analysis. Using 3D modeling technology, the GIS data, pictures, and video materials are processed three-dimensionally to generate a digital 3D model of the wind farm. Users can view the topographic features and site selection plans of the wind farm in 3D space and conduct precise analysis.

[0012] S5 Data archiving and subsequent utilization. After completing the site investigation work, all project data and materials are archived into the site investigation material database of the platform. The database is convenient for subsequent work query and use and provides basic data support for future project iteration and update.

[0013] S6 offline data collection and fast transmission. When the network conditions on site are poor, record the survey data such as pictures and GPS location information through mobile devices. When the network is restored, quickly upload the offline recorded data to the platform to ensure the timeliness and completeness of information transmission.

[0014] Furthermore, the key innovations of the present invention include multi-terminal interconnection, three-dimensional display technology, data synchronization and real-time update, detailed survey plan records, survey data database, and offline functions and fast transmission. Among them, multi-terminal interconnection supports access and operation from both computer and mobile terminals, breaking the time and space limitations of traditional wind farm site surveys. The three-dimensional display technology uses three-dimensional modeling technology to enhance the intuitiveness and vividness of data display. Data synchronization and real-time update ensure that all data is synchronized to the database in real time to ensure the accuracy and consistency of the data. Detailed survey plan records fully retain key information in the survey process by adding elements such as points, lines, and surfaces. The survey data database collects all survey data into the database, enhancing the traceability and utilization value of the data. Offline functions and fast transmission ensure the timeliness and integrity of data transmission in an unstable network environment.

[0015] In particular, the present invention achieves significant technical effects through the above-mentioned technical means. Data synchronization and real-time updating solve the management difficulties caused by information lag or data confusion in traditional methods, and improve the real-time operation and project management efficiency. The three-dimensional display and intuitiveness optimize the site selection decision-making process of wind farms and improve the success rate and benefits of projects. Centralized data management and archiving improve the retrievability and availability of information, and reduce management problems caused by scattered, lost or inconsistent versions of information. Offline data collection and rapid transmission improve the flexibility and reliability of data collection, and reduce project delays caused by untimely data transmission. Detailed survey plan records improve the accuracy and availability of data, and provide important data support for subsequent maintenance and expansion of the project.

[0026] The present invention provides a multi-terminal interconnected wind farm site investigation and selection method based on 3D modeling and GIS technology. By introducing modern information technology, this method realizes efficient data management, real-time synchronization, and intelligent decision-making support during the wind farm site investigation process, improving the accuracy, convenience, and overall efficiency of the site investigation. The following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0027] Project creation and configuration( Figure 3 )

[0028] Users first enter the platform of the present invention through the computer terminal 1 or the mobile terminal 2 to create a new wind farm site investigation project or update an existing project. The platform provides a variety of operation tools 26, and users can add, modify various elements (points, lines, surfaces, etc.) in the project according to actual needs. Specifically, users can add the layout of the wind turbines 11, anemometer towers 12, step-up substations 13, road paths 14, site investigation tracks 15, and field areas 16, so as to depict in detail the topography and potential construction locations of the wind farm. During the project creation and configuration process, users can intuitively select and edit these elements through the graphical interface of the platform to ensure the comprehensiveness and accuracy of the project.

[0029] Data synchronization and real-time update( Figure 4 )

[0030] During the reconnaissance process, all operations, whether on the computer terminal 1 or the mobile terminal 2, can be synchronized to the database 5 in real time. This synchronization process is achieved through a multi-terminal interconnection platform, ensuring that all project members can see the latest project information and avoiding problems of data lag and information inconsistency. Specifically, when a user performs an operation on the computer terminal 1 or the mobile terminal 2, the platform will immediately send these operation records to the database 5. The database 5 ensures the latest status of all data through a real-time update mechanism 27. For example, when a user adds a new location of the wind measurement tower 12 on the mobile terminal 2, this information will be immediately synchronized to the database 5 and displayed in real time on the computer terminal 1. This feature not only improves the real-time nature of operations but also makes project management and decision-making more efficient and accurate.

[0031] Reconnaissance Plan and Information Recording( Figure 5 )

[0032] When a user creates a new reconnaissance plan, based on the basic information of existing projects, a complete reconnaissance plan can be formed by adding new elements such as points, lines, and surfaces. The detailed information of each reconnaissance point (such as name, description, longitude and latitude, etc.) will be recorded, and pictures or video materials taken on-site can be attached. The specific steps are as follows:

[0033] 1. The user selects elements such as points, lines, and surfaces to be added in the project display layer 25 of the platform.

[0034] 2. Through the operation tool 26, the user can accurately mark the position of each element on the map.

[0035] 3. For each reconnaissance point, the user can input detailed name, description, and longitude and latitude information.

[0036] 4. The user can also take on-site pictures with the camera 8 of the mobile terminal 2 and attach these pictures to the corresponding reconnaissance points through the platform.

[0037] 5. Similarly, the user can record on-site video materials and upload them to the platform.

[0038] 6. All this information will be automatically recorded by the platform and saved to the database 5 to ensure that the information of each reconnaissance point is completely and accurately retained.

[0039] 3D Display and Analysis( Figure 6 )

[0040] To more intuitively display the terrain, landforms, and surrounding environment of a wind farm, the present invention uses three-dimensional modeling technology 17 to three-dimensionally process GIS data 18, picture materials 19, and video materials 20 to generate a digital three-dimensional model of the wind farm. Users can view the terrain features and site selection plans of the wind farm in three-dimensional space and conduct precise analysis. The specific steps are as follows:

[0041] The platform extracts GIS data 18, picture materials 19, and video materials 20 from the database 5.

[0042] Through three-dimensional modeling technology 17, the platform processes these data into a three-dimensional model.

[0043] Users can view the layouts of key facilities such as wind turbines 11, wind measurement towers 12, and booster stations 13 in the three-dimensional view.

[0044] The three-dimensional model also supports users to view the terrain and landforms of the wind farm from different angles and heights, helping users to more comprehensively understand the geographical information of the site.

[0045] Users can conduct analysis of wind energy capture efficiency in three-dimensional space, quickly identify terrain obstacles or areas unsuitable for construction, thereby optimizing the site selection decision-making process of the wind farm.

[0046] Data Archiving and Subsequent Utilization( Figure 7 )

[0047] After completing the site inspection work, users can archive all project data and materials into the site inspection data database 21 of the platform for easy query, analysis, and management of subsequent work. The site inspection data database 21 not only supports the storage and query of materials but also provides basic data support for future project iteration and update. The specific steps are as follows:

[0048] Users select the project data and materials to be archived through the archiving function of the platform.

[0049] The platform automatically uploads these data and materials to the site inspection data database 21.

[0050] The database 21 supports standardized material archiving to ensure the consistency and integrity of materials.

[0051] Users can query and retrieve materials in the database 21 for convenient later project review and data analysis.

[0052] The site inspection data database 21 also supports version control 28 to ensure that different versions of materials can be clearly managed and traced.

[0053] Offline Data Collection and Fast Transmission( Figure 8 )

[0054] In the case of poor on-site network conditions, the present invention provides an offline data collection function. Users can record on-site survey data, such as pictures, GPS positions, etc. through the mobile device 2. After the network is restored, the offline-recorded data can be quickly uploaded to the platform. The specific steps are as follows:

[0055] The user starts the offline data collection mode on the mobile device 2.

[0056] The user uses the GPS locator 7 of the mobile device 2 to record the longitude and latitude information of the on-site survey point.

[0057] The user takes on-site pictures through the camera 8 of the mobile device 2 and records relevant descriptions.

[0058] The user can also record on-site video data and attach it to the corresponding on-site survey point.

[0059] When the network is restored, the user uploads all the recorded data to the database 5 quickly through the offline data upload function of the platform.

[0060] 6. The database 5 automatically processes these offline data to ensure the timeliness and integrity of information transmission.

[0061] Specific application scenarios

[0062] Suppose a wind farm project is located in a remote mountainous area with complex terrain and unstable network signals. The project team needs to conduct detailed on-site survey and site selection work to ensure the smooth progress of the wind farm construction. The following is a detailed description of the specific application scenario:

[0063] 1. Project creation and configuration

[0064] The project team enters the platform through the computer terminal 1 to create a new wind farm on-site survey project.

[0065] In the project display layer 25, team members use the operation tool 26 to add elements such as wind turbines 11, wind measurement towers 12, booster stations 13, road paths 14, on-site survey trajectories 15, and site areas 16.

[0066] Through the graphical interface of the platform, team members can accurately mark the positions of each facility and input detailed names, descriptions, and longitude and latitude information.

[0067] 2. Data synchronization and real-time update

[0068] After the project is created, team members enter the platform through the mobile device 2 to start on-site survey.

[0069] Each member records the detailed information of the on-site survey point in real time on the mobile device 2, including name, description, longitude and latitude, etc.

[0070] All the recorded data is synchronously transferred to database 5 in real time through the platform, ensuring that all team members can view the latest project information.

[0071] For example, when a team member adds the location of a new wind measurement tower 12 on the mobile device 2, this information is immediately synchronized to database 5 and is displayed in real time on the computer devices 1 and mobile devices 2 of other team members.

[0072] 3. Reconnaissance Plan and Information Recording

[0073] During the on-site reconnaissance process, team members use the camera 8 on the mobile device 2 to take on-site pictures of each reconnaissance point and attach these pictures to the corresponding reconnaissance points through the platform.

[0074] Team members can also record on-site video materials and upload them to the platform.

[0075] All this information will be automatically recorded by the platform and saved in database 5, ensuring that the information of each reconnaissance point is completely and accurately retained.

[0076] For example, team members took multiple pictures from different angles at the location of a certain wind measurement tower 12 and recorded detailed descriptions, and this information can be conveniently viewed and managed in the platform.

[0077] 4. 3D Display and Analysis

[0078] After the project team completes the preliminary reconnaissance, through the 3D modeling function 17 of the platform, the GIS data 18, picture materials 19 and video materials 20 are processed into a 3D model.

[0079] Team members can view the terrain features, potential construction locations and key facility layouts of the wind farm in the 3D view.

[0080] The 3D model supports users to view the terrain and landforms of the wind farm from different angles and heights, helping users to more comprehensively understand the geographical information of the site.

[0081] Team members can conduct an analysis of the wind energy capture efficiency in the 3D space, quickly identify terrain obstacles or areas unsuitable for construction, thereby optimizing the site selection decision-making process of the wind farm.

[0082] For example, team members found in the 3D view that the terrain of a certain area is not conducive to the layout of the wind turbines 11, so they adjusted the site selection plan, improving the power generation efficiency of the wind farm.

[0083] 5. Data Archiving and Subsequent Utilization

[0084] After the reconnaissance work is completed, the project team uploads all project data and materials to the reconnaissance data database 21 through the archiving function of the platform.

[0085] The on-site investigation data database 21 supports standardized data archiving to ensure the consistency and integrity of the data.

[0086] Team members can query and retrieve data in the database 21, facilitating subsequent project review and data analysis.

[0087] The on-site investigation data database 21 also supports version control 28 to ensure clear management and traceability of different versions of data.

[0088] For example, during the subsequent project review, the project team quickly found the detailed records of a certain on-site investigation through the database 21, providing important data support for the further optimization of the project.

[0089] 6. Offline Data Collection and Fast Transmission

[0090] In the case of poor on-site network conditions, project team members start the offline data collection mode through the mobile device 2.

[0091] Team members use the GPS locator 7 of the mobile device 2 to record the longitude and latitude information of the on-site investigation points.

[0092] Team members take on-site pictures through the camera 8 of the mobile device 2 and record relevant descriptions.

[0093] Team members can also record on-site video materials and attach them to the corresponding on-site investigation points.

[0094] When the network is restored, team members quickly upload all the recorded data to the database 5 through the offline data upload function of the platform.

[0095] The database 5 will automatically process these offline data to ensure the timeliness and integrity of information transmission.

[0096] For example, team members conducted multiple offline data collections in a remote mountainous area. After returning to an area with network signal, they quickly uploaded all the data to the platform, ensuring the integrity and timeliness of the data.

[0097] The beneficial effects of the present invention are as follows:

[0098] The present invention supports the access and operation of the computer terminal 1 and the mobile device 2. Users can view, edit, and manage project information anytime and anywhere, breaking the time and space limitations of traditional on-site investigation and site selection for wind farms.
