With the changes of time, urban construction, road reconstruction, pipeline construction and other factors, the database will lose its timeliness. In order to grasp the current situation of underground pipelines, it is necessary to conduct multiple surveys, which not only wastes government financial, human and material resources, but also may provide incorrect information to decision makers, resulting in decision-making errors. At the same time, after the underground pipeline survey, there are few cities that can truly update the underground pipeline database dynamically. In the prior art, the data related to the pipeline is diverse, and most of the big data related to the pipeline is associated with different geographic areas, which may need to call the big data resources of the corresponding geographic area, and combine the called resources to detect, exchange and manage the field data; and the data accumulated in the process of daily maintenance and repair of the pipeline cannot be summarized and updated in real time, so that the pipeline operation and data operation are independent of each other and cannot be coordinated with each other, resulting in low overall operation efficiency.

Specifically, the following steps are included: S2-1 decomposes the elements of the structure from the spatial geometry structure of the pipeline data, as shown in Figure 4 ​​The oil pipeline shown, the corresponding pipe wall, top and bottom of the oil pipeline, the electronic nose on the pipeline segment, the image monitoring device on the pipe wall, top and bottom (not shown in the figure), and the functional room inside the pipeline (not shown in the figure), including an accessible room for monitoring the operating status of multiple preset pipeline sections, a reserve of tools for repairing pipeline sections, and a reserve of sensors, metering devices, and image monitoring devices for updating.

[0050] S2-2 selects any point (e.g., point a1 and point a2) in the component according to the digital map coordinate system, and records the coordinates of the point and the component data resources related to the component in the database; S2-3 establishes a mapping relationship between the component data resource and the coordinates of the point.

[0051] S3 builds a database functionalization module so that, in addition to calling and / or updating data in the database, it can also perform data quality inspection, data conversion and distribution, data governance, and data services on the called and / or updated data; S4 is based on the pipeline geographic digital map, mapping relationship, and functional modules constructed in S1-S3, and according to the operation requirements or the area of ​​interest, circles a first area in the pipeline geographic digital map, and / or assigns personnel wearing augmented reality (AR) devices to arrive at the designated location along a predetermined route and circle a second area according to a pre-set circle program. Alternatively, the second area is circled according to a pre-set circle program, and personnel wearing augmented reality (AR) devices are assigned to arrive at the designated location along a predetermined route. Then, the calling and / or updating operations are performed on the first area and / or the second area, and / or data quality inspection, data conversion and distribution, data governance, and data services are performed on the called data and / or the updated data.

[0052] Example 2 The functional modules in S3 include data quality inspection module, data conversion and distribution module, data governance module, and data service management module.

[0053] The data quality inspection module includes a warehouse data quality inspection item module for including mathematical basis inspection, achievement integrity inspection, logic consistency inspection, table data inspection, metadata inspection; achievement data quality inspection items including achievement integrity inspection, logic consistency inspection, table data inspection, spatial topology inspection, attribute inspection, elevation inspection, raster inspection, OSGB inspection, point cloud inspection, map finishing inspection, and origin inspection; and an inspection result output module for including CAD file inspection result output, GIS data file inspection result output, and other inspection result output modules for including image inspection, file organization structure inspection, and output of Excel file indicating error types and error information.

[0054] The data conversion and distribution module includes a data conversion module and a data distribution module. The data conversion module is used for cleaning and format conversion of CAD data, including layer coding mapping, attribute field mapping, attribute value standardization processing, and graphic attribute hanging operation, so that the converted data meets the specifications and requirements of GIS warehouse management, and when data is distributed, the data in the management database can be converted into production CAD data format again, specifically including coordinate system conversion, data range vectorization, and CAD drawing. The data distribution module is used for realizing data distribution function, extracting data in the database according to specified data range, layer list and other conditions, converting the data into specified coordinate system and data format for distribution. According to the application scenario, the distributed data adopts two distribution modes of user data distribution list and project data distribution list, and is also used for completing data distribution audit, data distribution record, and distributed data download.

[0055] The data management module is constructed based on data function service, used for writing FME template to realize various data management items, and publishing the data management items as FME service. The FME service is aggregated into a management scheme service for different data through the data function service, and finally registered to the system to form a data management function. The data management mainly manages the unit internal production or subcontracted pipeline project data, automatically manages according to the data quality inspection problems according to the standard, and specifically includes origin management and CAD map management.

[0056] The service management module is used to register and publish spatial data services, thematic data services, data quality inspection services, and data exchange services, form a service list, and keep service audit records. It also performs service registration, deactivates, activates, and deletes registered services. It also performs service retrieval, including querying services in the official service list, searching by service name, description, key, and tag information, and returning a list of qualified services. It also provides data function services and aggregation and task management functions for FME template services. The service management module provides spatial ETL capabilities based on FME, extracting, transforming, and loading spatial data. It supports reading and writing operations in multiple source data formats, several spatial coordinate systems, and coordinate transformation models. It also provides data classification statistics, spatial data analysis, aggregation, classification, and spatial operations. It uses visual modeling to quickly implement multiple data integration and transformation models, and realizes functional services for multiple data processing.

[0057] Figure 6 This is the interface diagram for the data function service. The data function module provides aggregation and task management capabilities for FME template services. The system leverages FME to provide spatial ETL capabilities, extracting, transforming, and loading spatial data. It supports reading and writing data in multiple source formats, several spatial coordinate systems, and coordinate transformation models. It also provides various algorithms for data classification statistics, spatial data extraction, aggregation, classification, and spatial operations. Using visual modeling, it rapidly implements multiple data integration and transformation models, enabling a variety of data processing services.

[0058] Figure 7 Create the FME data quality inspection template interface diagram, use FME to develop various data quality inspection and conversion models, form an FME template library, and manage FME. This includes categorizing and registering templates, including classification, functional description, operating instructions, applicable department / project, author, department, registration date, and update date.

[0059] Figure 8 This is the FME data quality inspection aggregation service interface diagram, which enables publishing FME templates as FME services. By aggregating multiple FME services, single-function FME spatial data processing services are aggregated into new services that can complete complex tasks. Data quality inspection, data exchange and data governance functional services are flexibly combined on demand to form new customized functional services.

[0060] The Data Processing Service Collection interface allows users to customize data processing services. Users can build and configure complex data processing functions based on FME templates and publish them as services. This includes services such as data conversion, coordinate transformation, and data quality inspection. Aggregated data processing services are registered with the system service list for unified review and management.

[0061] Figure 9 This is the data processing task management interface. Data function services are executed as tasks, and each service call is converted into a managed task. The system records information such as task execution status, execution start time, call parameters, completion time, run logs, and service callers to form a task list. The system provides task pause and resume functions, supporting the suspension (pause) and resumption (continue) of ongoing tasks. This ensures high availability of data tasks, ensuring that data tasks are not lost and execution is uninterrupted. Task recovery capabilities are provided for system errors, system crashes, power outages, and other situations that occur during task execution. Once the fault is resolved, the task remains active and continues running from the point where it was interrupted. FME services within data tasks can be called concurrently, allowing multiple FME services to be called simultaneously for data processing, fully utilizing computer resources and improving task execution efficiency.

[0062] Example 3 In general, the method for encircling any circled first area and second area in S2 and S4 is as follows: P1 selects three or more points in the pipeline geographic digital map and connects the points to form a polygon; P2 draws a circumscribed circle for the polygon as the first area and the second area; The method for circling according to the pre-set circling program in Example 1 is as follows: like Figure 10 As shown, Q1 takes the designated location as the center and a radius of 5m to form a second area, or Q2 takes the geographical location of the person wearing the AR device as the starting point, Figure 10 Select 6 points at different distances from the base point in a, and then connect the points to form the first polygon ( Figure 10 b), making a first circumscribed circle of the polygon as the second area ( Figure 10 d). By using the geographic location of the person wearing the AR device as the base point, the second area can be dynamically selected based on the location of the AR device. This allows the person to see different underground electronic nose locations on the digital map depending on their location, allowing for comparison with the on-site scene.

[0063] Furthermore, multiple points are selected outside the first circumscribed circle, and the points are connected to form a second polygon ( Figure 10 c), draw a second circumscribed circle for the second polygon as the second area ( Figure 10 d).

[0064] The circumscribed circle means that there are at least two common points between the circle and the vertices of the polygon, and the polygon is contained in the circumscribed circle. Figure 10In d, the first circumscribed circle and the first polygon have only two common points, and the second circumscribed circle and the second polygon also have only two common points.

[0065] The calling and updating method is to find the selected points of the elements in the circled first area and / or the second area, to call the corresponding data resources in the database according to the coordinates of the points in the digital map coordinate system, and to return the data resources to complete the calling, and to return to the database for storage after updating the returned data, and to record the update history. Figure 10 a-c, the corresponding Figure 5 For example, point a1 in a, 5b, find the relevant data resources in the database according to the coordinates of a1 in the digital map coordinate system, and return the data resources to complete the calling, and return to the database for storage after updating the returned data, and record the update history.
