Description

Technical Field

[0001] This invention relates to the field of rail transit line design technology, and in particular to a rail transit line design system and method based on scheme management. Background Technology

[0002] With the rapid development of urbanization in my country, the demand for intercity and urban rail transit construction is increasing daily. As a crucial component of modern urban transportation, rail transit planning and design not only affects urban traffic efficiency but also directly impacts sustainable urban development. Rail transit line design is a complex, multidisciplinary project involving civil engineering, electrical engineering, communication and signaling, and other professional fields. Through long-term practice, my country's rail transit design professionals have accumulated rich experience and established practices. This valuable knowledge needs to be effectively inherited and utilized to improve the quality and efficiency of subsequent projects.

[0003] Most existing rail transit line design software is developed based on traditional computer-aided design platforms, such as AutoCAD. These software programs are relatively mature in basic alignment design, capable of meeting designers' basic needs for horizontal and vertical alignment. However, their functionality is often limited to the design of single lines, lacking effective management and integration of overall project plans. In actual design processes, rail transit line design typically requires multiple iterations, resulting in multiple design schemes. Designers need to frequently adjust and optimize line directions, station locations, and wiring layouts. Furthermore, rail transit projects usually involve collaborative work across multiple disciplines, such as civil engineering, power supply, communications, and signaling. Close cooperation between these disciplines is essential to ensure the feasibility and rationality of the design scheme.

[0004] While existing rail transit line design software has improved design efficiency to some extent, it still has significant shortcomings in scheme management and multi-disciplinary collaboration. First, existing software lacks a comprehensive management mechanism for design schemes, failing to effectively record and track design data from different versions, leading to data loss or confusion during the design process. Second, existing software is weak in integrating multi-disciplinary interfaces, making it difficult to achieve cross-disciplinary data sharing and collaborative design, increasing the complexity and uncertainty of the design work. Finally, existing software is not flexible enough in customizing design specifications and drawing standards, failing to fully meet the personalized needs of different projects and regions. These problems limit the overall efficiency and quality of rail transit line design, urgently requiring a new design method and system to address these shortcomings and improve the scientific rigor and standardization of the design work. Summary of the Invention

[0040] This invention provides a rail transit line design system and method based on scheme management. Through this system and method, designers can establish a line scheme management mechanism around rail transit line design, and manage technical standards, line design data, and interface data with other disciplines through tagging. This mechanism runs throughout the entire design process. When designers operate on lines, stations, and other tagged entities, they will query the relationships between objects through the scheme management mechanism and complete a series of operations such as adding, deleting, modifying, updating, querying, and editing. Corresponding operation tools will interact with the scheme management mechanism to obtain the logical relationships between objects. Simultaneously, the system forms data packages based on individual schemes, managing and interacting around the schemes from a timeline perspective, meeting the needs of iterative design during the design process. Compared with other systems and methods currently available, this system and method not only optimizes the line design process and tools but also provides a solution for the iterative data management of design schemes, greatly improving the efficiency and accuracy of rail transit line design from the perspective of the entire design cycle.

[0041] Example 1:

[0042] like Figure 1 As shown, this embodiment of the invention provides a rail transit line design system based on scheme management, including:

[0043] The system comprises the following modules: scheme information creation, track alignment design, track ancillary marker design, digital ground model interpolation, track longitudinal slope design, horizontal and vertical drawing layout output, and track data table output. The scheme information creation module includes a scheme list, initial scheme dataset, and a scheme management tool set. The track alignment design module includes custom track entities and a track alignment design tool set. The track ancillary marker design module includes custom track station entities, custom track turnout entities, custom intersection marker entities, a set of track station design tools, a set of track turnout design tools, and a set of track intersection marker tools. The digital ground model interpolation module includes a triangulation model, a set of terrain processing tools, and custom ground line entities. The track longitudinal slope design module includes custom slope entities and a set of track longitudinal profile design tools.

[0044] like Figure 2 As shown, this system utilizes the dictionary base class object of the AutoCAD platform to derive two classes: a scheme list dictionary derived class and a scheme dataset dictionary derived class. Based on these, a scheme management data model is constructed. After instantiation, the scheme list dictionary derived class object is unique within the CAD DWG drawing space, used to record the ID of all scheme dictionaries in that drawing space. The scheme dataset dictionary derived class object is instantiated according to the specific circumstances of the route scheme. Multiple route scheme dataset dictionary objects can exist within the same DWG drawing space. The dictionary stores the IDs of related data objects, such as the IDs of custom entity objects like lines, stations, wiring, and labels. Data of related objects can be directly accessed and manipulated through these IDs. The scheme file I / O toolset supports saving and retrieving scheme datasets in the DWG drawing space, including scheme data and drawing representation styles, all of which can be saved as PLN custom format files. The object ID check-in toolset supports picking and checking custom entity objects such as lines, stations, wiring, and labels from the DWG drawing space, used to instantiate scheme datasets and establish the association between schemes and objects. The scheme information toolset allows designers to set the overall technical standards and main parameters of the scheme, thereby determining relevant design specifications and drawing standards to constrain and control the subsequent design process. The add, delete, modify, and update toolset not only allows designers to create, delete, modify, and update schemes in the scheme list, but also supports the conversion of data formats from different versions.

[0045] like Figure 3As shown, this system can complete the selection, alignment, and detailed design of the horizontal alignment of a planned route through the route plan design module. The system provides a set of route plan design tools, allowing designers to directly manipulate custom entity objects of the route, designing single route directions, alignment combinations, mileage settings, and spatial and mileage relationships between multiple routes. This system utilizes the entity base class objects of the AutoCAD platform for derivation, and through special design and customization based on the object elements and characteristics of urban rail transit lines, it forms custom entity objects of the route. These objects contain three types of data: intersection information, including data on all intersection points of the route plan, such as coordinates, radius, length of transition curves before and after, and the resulting horizontal alignment data; chainage information, including all internal and external chainage information within the starting mileage and route length; and drawing styles, including the starting and ending points, mileage markers in hundreds of meters, feature points, curve element markers, and the line type, thickness, text style, position, height, and other display requirements of the route itself. The route custom entity object also includes five major categories of interfaces: the intersection editing interface set supports accessing and editing the intersection information of the route entity; the chain break editing interface supports accessing and editing the chain break information of the route entity; the style editing interface supports accessing and editing the drawing style of the route entity; the mileage positioning interface supports accessing and querying the coordinates, azimuth, mileage, and alignment information of any mileage point on the route; and the geometric projection interface supports locating the projection point coordinates, azimuth, mileage, and alignment information of any point outside the route on the line. The route plan design module's route plan design tool set includes various planar route design tools. The scheme file I / O tool set includes three commands: open track, save track, and open ULI, supporting disk access operations for route custom entity objects in RSL and ULI custom file formats. The style attribute tool set includes two commands: attribute setting and technical standards. The intersection editing tool set includes three functions: insert intersection, modify intersection, and delete intersection. The straight line editing tool set includes three functions: full line offset, offset straight line, and adjust parallel lines. The curve editing toolset includes three functions: curve tangent circle, reverse curve, and dot-line spacing. The combination editing toolset includes four functions: convert to design line, reverse line, break line, and merge line. The double-line editing toolset includes four functions: generate double lines, adjust the spacing between two lines, adjust concentric circles, and adjust line spacing. The broken chain editing toolset includes nine functions: modify the starting point, add a broken chain, delete a broken chain, modify the chain length, move a broken chain, switch broken chains, one-click internal link, update internal links, and a broken chain list.

[0046] like Figure 4As shown, this system uses the track ancillary marking design module to complete the marking design of ancillary facilities or intersecting features related to the designed track. Ancillary facilities include track stations, turnouts, ancillary structural facilities, structural boundaries, etc., while intersecting features include roads, rivers, pipelines, cables, etc. Figure 4As shown, the system provides a large set of entities and tools, enabling designers to determine information such as the mileage, characteristics, and control requirements of ancillary facilities or intersecting features through line ancillary annotation design. This system utilizes the entity base class objects of the AutoCAD platform for derivation. Based on the relevant ancillary facility elements and characteristics of urban rail transit lines, custom entity objects such as line stations, line turnouts, ancillary structural facilities, and structural boundary facilities are formed through special design and customization. Based on the intersecting feature elements and characteristics of urban rail transit lines, custom entity objects such as intersecting roads, rivers, pipelines, and cable facilities are formed through special design and customization. The custom entity object for line stations includes three types of data: station center point information, platform size information, and station flag drawing style information, along with corresponding data information editing interfaces. The custom entity object for line turnouts includes three types of data: turnout center location information, model and size information, and turnout style information, along with corresponding data information editing interfaces. Custom entity objects for ancillary structural facilities, structural boundary facilities, intersecting roads, rivers, pipelines, and cable facilities all include three types of data: intersection location information, object size information, and annotation style information, along with corresponding data information editing interfaces. This system provides corresponding design toolkits for custom entity objects related to different lines or intersecting features. For custom entity objects of line stations, the system offers a line station design toolkit, including a file I / O toolkit with functions to open and save stations, supporting hard drive access to CZ custom format files; a style attribute toolkit with functions to insert and modify stations; and a location editing toolkit with functions to modify mileage and update stations. For custom entity objects of line turnouts, combined with the design needs of track layout, the system provides a line turnout design toolkit. This includes a file I / O toolkit with functions to open and save turnouts, supporting hard drive access to DC custom format files; a model style toolkit with functions to add turnouts, add stoppers, add turnout labels, and update turnout labels; a location editing toolkit that supports moving and editing the pick points of turnout entities; and a combined track layout toolkit with functions to add single crossovers, crossovers, shorten crossovers, shorten connections, double parking lines, and single parking lines. For custom entity objects of ancillary structures, structural boundary facilities, intersecting roads, rivers, pipelines, and cables, and in accordance with the design requirements of intersection labeling, the system provides an intersection labeling toolset. The file I / O toolset includes two functions: opening line labels and saving line labels, and supports hard drive access operations for XLB custom format files. The style attribute toolset includes modification functions for 6 labeling styles. The position editing toolset supports moving and editing operations of the pick points of 6 types of labeling entities. The add, delete, and update toolset includes functions for adding, deleting, modifying, and updating 6 types of labeling entities.

[0047] like Figure 5As shown, this system uses a digital terrain model interpolation module to extract and edit the ground lines at each stake of the designed route. The specific steps involve processing the DWG topographic map, extracting effective elevation data, constructing a digital terrain model, allowing the route object to interact with the digital terrain model, and generating custom entities for the route's ground lines at each stake, such as... Figure 5 As shown, the system provides a toolset that allows designers to create triangulated digital terrain models (TGDs) from topographic maps and to acquire and edit ground lines. This system focuses on terrain fitting and utilizes the Delaunay triangulation algorithm to develop and construct a digital terrain model. The model contains three datasets: vertex object dataset, edge object dataset, and triangle object dataset. Points, lines, and faces together constitute the basic geometric entities of the triangulation model. The initial creation module of the triangulation model instantiates the vertex object set, edge object set, and triangle object set of the model based on externally imported elevation point data, constructing the entire triangulation model entity. The model I / O module supports exporting the vertex object set, edge object set, triangle object set, and their corresponding relational models of the instantiated triangulation model to a specified text format file. It also supports importing specified text format files into the model to re-instantiate the triangulation model. The location query module supports elevation queries for any point within the triangulation area. Specifically, it uses trajectory search to locate the triangle containing the query point and then uses trigonometric interpolation to calculate the elevation of the query point. The system has developed and customized a ground line entity based on the annotation style of each ground point along the route. This entity primarily stores the ground point set information obtained by interpolation along the route and its drawing style information, and provides an external interface for editing and adjusting the ground points and their drawing styles. The system provides a set of 12 design tools for terrain processing, digital terrain models, and ground line objects. These include terrain processing tools such as frame cutting and terrain trimming, as well as terrain modeling tools such as triangular mesh modeling, saving, and importing. For ground line objects, the system provides tools for cutting and generating ground line objects, saving files, importing files, manually adding stakes, adding stakes from files, and modifying elevations.

[0048] like Figure 6As shown, this system completes longitudinal profile design and standard longitudinal profile drawing through a longitudinal slope design module. The specific steps involve extracting the planar information of the custom entity along the line and the ground point information of each stake along the line to initialize and generate a slope entity object. This allows designers to interactively design the slope entity object, adjusting slope points, gradients, and standard styles. The final design yields the vertical curve of the longitudinal profile, and a standard longitudinal profile drawing is generated by combining the horizontal and vertical alignments and adding markers. The system provides a set of longitudinal profile design tools, which designers can use to directly manipulate the custom slope entity object. Based on the design habits of longitudinal profile slope design and standard longitudinal profile drawing, this system derives from the entity base class object of the AutoCAD platform to construct a custom slope entity object. This object contains planar information such as plane intersections and chainage breaks, longitudinal information such as slope change points, and slope drawing style information including scales, grids, scale bars, longitudinal parameters, and drawing parameters. The slope-adjustment custom entity object also includes six main types of interfaces: a planar information editing interface that supports accessing and editing information such as planar intersections, chain breaks, and horizontal curves; a grid attribute interface that supports accessing and editing parameters such as longitudinal profile grid size and scale; a slope change point editing interface that supports accessing and editing slope change point elevation, mileage, and vertical curve parameters; an elevation query interface that supports locating and querying the elevation of the line at any mileage; a longitudinal profile column editing interface that supports customizing and editing the style and column parameters of the standard longitudinal profile drawing; and a longitudinal profile labeling interface that supports editing and customizing the labeling of auxiliary lines on the longitudinal profile. This system provides a corresponding set of line longitudinal profile design tools for the longitudinal profile slope-adjustment entity object. The File I / O toolset includes 6 tools for saving and importing files in specified formats, such as slope maps, vertical curves, and ground lines; the Style Attributes toolset includes 2 tools for setting scales and modifying parameters; the Slope Initialization toolset includes 2 tools for slope initialization and simple grid drawing; the Slope Change Point Editing toolset includes 4 direct operation tools for adding, deleting, and modifying slope change points, and projecting vertical curves, as well as 3 indirect operation tools for slope change points, such as slope modification, combined slope adjustment, and moving slope segments; the Cut-and-Fill Height Query toolset includes 4 tools for calculating the lowest point, viewing cut-and-fill height, calculating cut-and-fill height, and elevation points; the Longitudinal Profile Drawing toolset includes 1 tool for drawing standard longitudinal profiles; and the Longitudinal Profile Marking toolset includes 5 tools for updating, clearing, and modifying longitudinal profile markings, adding markers to the lowest point column, and adding markers to pump station heights.

[0049] like Figure 7As shown, this system completes the design and output of plan and longitudinal section drawings through the plan and longitudinal section drawing layout output unit. The specific steps involve designing the layout using three types of custom entity objects: standard plan view frames, longitudinal section view frames, and plan folded view frames. Then, all drawings are generated with a single click using the layout. The system provides corresponding toolsets around these three types of view frames. Based on the design habits for plan and longitudinal section drawings, this system derives from the entity base class objects of the AutoCAD platform to construct three types of custom entity objects: standard plan view frames, longitudinal section view frames, and plan folded view frames. The standard plan view frame object includes the length and width dimensions of the planar rectangular view frame, the lower right corner base point of the view frame, the view frame display aperture ratio, and other planar view frame information, as well as corresponding information editing interfaces. The longitudinal section view frame object includes the length and width dimensions of four rectangular view frames and the spacing between them, the lower right corner base point of the lower right view frame in each of the four view frames, the view frame display aperture ratio, and other longitudinal section view frame information, as well as corresponding information editing interfaces. The planar folded drawing frame object includes information such as the drawing sheet height, polyline inflection points of the drawing frame axis, and the display scale of the drawing frame, as well as corresponding information editing interfaces. This system provides five tools for creating and modifying planar drawing frames, saving and importing planar drawing frame files, and generating planar drawing frame layouts, all based on custom entity objects for the planar standard drawing frame. It also provides five tools for creating and modifying longitudinal section drawing frames, saving and importing planar drawing frame files, and generating longitudinal section drawing frame layouts, all based on custom entity objects for the planar folded drawing frame. Finally, it provides seven tools for creating and modifying planar drawing frames, adding and deleting inflection points, saving and importing planar folded drawing frame files, and generating planar folded drawing frame layouts with a single click.

[0050] like Figure 8 As shown, this system uses a route data table output module to complete the table output of route design results. Based on the route scheme management data model, the system extracts and processes the data before outputting it. Output can be done via text tables in Office or WPS Office software, or as CAD graphic tables. Fifteen table formats are designed according to the application scenarios of route output. Among them, the system provides designers with a set of 10 route result table output tools based on the route scheme management data model. The horizontal curve table, horizontal curve statistics table, stakeout table, vertical curve table, and slope statistics table all support single-line and double-line table output, while the line spacing table, line station characteristic table, control point result table, and coordinate result table are all for outputting the overall route scheme.

[0059] S700: The corresponding table data and format are generated by extracting and processing the data according to the corresponding line result table tool in the line data table output unit.

[0060] In summary, this system and method establish a route scheme management mechanism around rail transit line design. It manages technical standards, route design data, and interface data with other disciplines through tagging. This mechanism runs throughout the entire design process. When designers operate on routes, stations, and other tagged entities, they query the relationships between objects through the scheme management mechanism and complete a series of operations such as adding, deleting, modifying, updating, querying, and editing. Corresponding operation tools interact with the scheme management mechanism to obtain the logical relationships between objects. Simultaneously, the system forms data packages based on individual schemes, managing and interacting with schemes from a timeline perspective to meet the needs of iterative design processes. Compared with other methods and systems currently available, this method and system not only optimizes the route design process and tools but also provides a solution for the iterative data management of design schemes, significantly improving the efficiency and accuracy of rail transit line design from a full design cycle perspective.
