Description

Technical Field

[0001] The present invention relates to the technical field of rail transit line design, and in particular to a rail transit line design system and method based on scheme management. Background Art

[0002] With the accelerated development of my country's urbanization process, the construction demand for intercity and urban rail transit is growing. As an important part of modern urban transportation, the planning and design of rail transit is not only related to the city's traffic efficiency, but also directly affects the sustainable development of the city. Rail transit line design is a complex multidisciplinary project involving multiple professional fields such as civil engineering, electrical engineering, and communication signals. In long-term practice, my country's rail transit design practitioners have accumulated rich experience and habits. This valuable knowledge needs to be effectively inherited and utilized to improve the quality and efficiency of subsequent projects.

[0003] Most of the existing rail transit line design software is developed based on traditional computer-aided design platforms, such as AutoCAD. These software are relatively mature in basic line design and can meet the basic needs of designers for the horizontal and vertical lines of the line. However, their functions are often limited to the design of a single line, and lack effective management and integration of the overall project plan. In the actual design process, rail transit line design usually requires multiple iterations to form multiple design plans. Designers need to frequently adjust and optimize the line direction, station location, wiring layout, etc. In addition, rail transit projects usually involve the collaborative work of multiple disciplines, such as civil engineering, power supply, communication, signaling, etc., and each discipline needs to work closely together to ensure the feasibility and rationality of the design plan.

[0004] Although the existing rail transit line design software has improved the design efficiency to a certain extent, it still has obvious deficiencies in scheme management and multi-disciplinary collaboration. First, the existing software lacks a comprehensive management mechanism for the design scheme and cannot effectively record and track different versions of design data, which leads to data loss or confusion during the design process. Secondly, the existing software is weak in the integration of multi-disciplinary interfaces, making it difficult to achieve cross-disciplinary data sharing and collaborative design, which increases the complexity and uncertainty of the design work. Finally, the existing software is not flexible enough in the customization of design specifications and drawing standards, and cannot fully meet the personalized needs of different projects and regions. These problems limit the overall efficiency and quality of rail transit line design, and a new design method and system are urgently needed to solve these deficiencies and improve the scientificity and standardization of design work. Summary of the invention

[0044] like Figure 2 As shown in the figure, the system uses the dictionary base class object of the AutoCAD platform to derive, forming the scheme list dictionary derived class and the scheme data set dictionary derived class, and based on this, the scheme management data model is constructed. After the scheme list dictionary derived class object is instantiated, it is unique in the DWG graphic space of CAD, and is used to record the ID of all scheme dictionaries in the graphic space; the scheme data set dictionary derived class object is instantiated according to the specific situation of the line scheme. There can be multiple line scheme data set dictionary objects in the same DWG graphic space. The dictionary stores the ID of related data objects, such as the ID of custom entity objects such as lines, stations, wiring, and marking. The data of related objects can be directly accessed and operated through the ID. Among them, the scheme file I / O toolset can support the storage and retrieval of scheme data sets in the DWG graphic space, including scheme data, drawing expression style and other information can be saved as PLN custom format files; the object ID check-in toolset can support the picking and checking in of custom entity objects such as lines, stations, wiring, and marking in the DWG graphic space, which is used to instantiate scheme data sets and form an association relationship between schemes and objects. The scheme information toolset supports designers to set the overall technical standards and main parameters of the scheme, and then determine the relevant design specifications and drawing standards to constrain and control the subsequent design process. The add, delete, modify and update toolset not only supports designers to create, delete, modify and update schemes in the scheme list, but also supports the conversion of different versions of data formats.

[0045] like Figure 3As shown in the figure, this system can complete the line selection, alignment, and detailed design of the plane line type of the designed line through the line plane design module. The system provides a set of line plane design tools, which designers can use to directly operate the line custom entity objects, and design the single line direction, line type combination, mileage setting, and the space and mileage comparison relationship between multiple lines. This system uses the entity base class object of the AutoCAD platform for deriving, and around the object elements and features of the urban rail transit line, it has formed a line custom entity object through special design and customization. The object contains three types of data, among which the intersection information contains the data information of all intersections of the line plane, such as coordinates, radius, length of the front and rear ease curves, and the plane line type data calculated thereby; the broken link information contains all the internal and external broken link information within the starting mileage and line length; the drawing style includes the starting and ending points, mileage hundred-meter marks, feature points, curve element marks, and the line type, thickness, text style, position, height and other display expression requirements of the line itself.

The combined editing tool set includes four functions: convert design line, reverse line, break line, and merge line. The double line editing tool set includes four functions: generate double line, two line spacing, adjust concentric circles, and adjust line spacing. The broken link editing tool set includes nine functions: modify starting point, add broken links, delete broken links, modify chain length, move broken links, switch broken links, one-click internal links, update internal links, and broken link list.

[0046] like Figure 4As shown in the figure, this system uses the line auxiliary marking design module to complete the marking design of auxiliary facilities or intersecting features related to the design line. The auxiliary facilities include line stations, turnouts, auxiliary structural facilities, structural boundaries, etc., and the intersecting features include roads, rivers, pipelines, cables, etc. Figure 4As shown in the figure, the system provides a large number of entities and tool sets, so that designers can determine the mileage, characteristics, control requirements and other information of auxiliary facilities or intersecting features through the line auxiliary marking design. This system uses the entity base class object of the AutoCAD platform for derivation, and around the relevant auxiliary facility elements and features of the urban rail transit line, it has formed custom entity objects such as line stations, line turnouts, auxiliary structural facilities, and structural boundary facilities through special design and customization. Around the intersecting features and features of the urban rail transit line, it has formed custom entity objects such as intersecting roads, rivers, pipelines, and cable facilities through special design and customization. Among them, the line station custom entity object contains three types of data: station center point information, platform size information, and station flag drawing style information, as well as the corresponding data information editing interface. The line turnout custom entity object contains three types of data: turnout center position information, model size information, and turnout style information, as well as the corresponding data information editing interface. Custom entity objects such as auxiliary structural facilities, structural boundary facilities, intersecting roads, rivers, pipelines, and cable facilities all contain three types of data: intersection position information, object size information, and marking style information, as well as the corresponding data information editing interface. This system provides a corresponding set of design tools for customized entity objects of different line-related ancillary facilities or intersecting features. For customized entity objects of line stations, the system provides a line station design toolset, of which the file I / O toolset includes two functions: opening stations and saving stations, and supports hard disk access operations of CZ custom format files. The style attribute toolset includes two functions: inserting stations and modifying stations. The location editing toolset includes two functions: modifying mileage and updating stations. For customized entity objects of line turnouts, combined with the design needs of wiring, the system provides a line turnout design toolset, of which the file I / O toolset includes two functions: opening turnouts and saving turnouts, and supports hard disk access operations of DC custom format files. The model style toolset includes four functions: adding turnouts, adding car stops, turnout markings, and updating turnout marks. The location editing toolset supports the mobile editing of the pick-up points of turnout entities. The combined wiring toolset includes six functions: adding single crossovers, crossing crossovers, shortening crossovers, shortening connections, double stop lines, and single stop lines. In order to customize the entity objects of auxiliary structures, structural boundary facilities, intersecting roads, rivers, pipelines and cables, and in combination with the design needs of intersection marking, the system provides an intersection marking toolset. The file I / O toolset includes two functions: opening line marking and saving line marking. It supports hard disk access operations for XLB custom format files. The style attribute toolset includes the modification function of 6 marking styles. The position editing toolset supports the mobile editing operation of the picking points of the 6 marking entities. The add, delete and update toolset includes the functions of adding, deleting, modifying and updating the 6 marking entities.

[0047] like Figure 5As shown in the figure, this system uses the digital ground model interpolation module to complete the extraction and editing of the ground line of the designed line. The specific steps are to process the DWG topographic map, extract the effective elevation data, build the digital ground model, let the line object interact with the digital ground model, and generate the line ground line custom entity, such as Figure 5 As shown in the figure, the system provides a tool set that allows designers to create triangulated digital terrain models through terrain maps, and obtain and edit ground lines. This system uses the Delaunay triangulation algorithm to develop and construct a digital terrain model based on terrain fitting. The model contains three data sets, namely, vertex object data set, edge object data set, and triangle surface object data set. Points, lines, and surfaces together constitute the basic geometric entities of the triangulated network model. The function of the initial creation module of the triangulated network model is to instantiate the vertex object set, edge object set, and triangle surface object set of the model based on the externally imported elevation point data to construct the entire triangulated network model entity. The model I / O module supports the instantiated triangulated network model to export the vertex object set, edge object set, triangle surface object set and their corresponding relationship model into a specified text format file, and also supports importing the specified text format file into the model to re-instantiate the triangulated network model. The positioning query module supports elevation query of any point within the triangulated network range, specifically using trajectory search to locate the triangle where the query point is located, and then using the triangulation interpolation method to perform elevation interpolation calculation on the query point. The system has developed and customized a ground line custom entity based on the annotation style of the ground points of each stake along the route, which mainly stores the ground point set information and its drawing style information obtained by interpolating each stake along the route, and provides an external interface for editing and adjusting the ground points and their drawing styles. This system provides a corresponding set of design tools for terrain processing, digital ground models, and ground line objects of each stake, a total of 12 tools, such as terrain processing tools such as cutting cloth frame and cutting terrain, as well as triangulated network modeling, saving, importing and other ground modeling tools. For ground line objects, it provides tools such as cutting and generating ground line objects, saving files, importing files, adding stakes manually, adding stakes to files, and modifying elevations.

[0048] like Figure 6As shown in the figure, this system completes the longitudinal section design and the drawing of the standard longitudinal section through the line longitudinal slope design module. The specific steps are to extract the plane information of the line custom entity and the ground point information of the ground line entity along the line, initialize and generate the slope entity object, so that the designer can interactively design the slope change point, slope section slope, standard style adjustment and other interactive designs for the slope entity object, and finally obtain the vertical curve result of the longitudinal section, and combine the horizontal and vertical and add standards to generate the standard longitudinal section diagram. The system provides a set of line longitudinal section design tools, which the designer can use to directly operate the slope custom entity object. This system is based on the design habits of longitudinal section slope design and standard longitudinal section drawing, and is derived from the entity base class object of the AutoCAD platform to construct a slope custom entity object. The object contains plane information such as plane intersections and mileage broken links, longitudinal section information such as slope change points, and slope drawing style information including rulers, grids, scales, longitudinal section parameters, and drawing parameters. The slope custom entity object also includes 6 major types of interfaces. The plane information editing interface supports access and editing of plane intersections, broken links, flat curves and other information; the grid attribute interface supports access and editing of parameters such as longitudinal section grid size and scale; the slope change point editing interface supports access and editing of slope change point elevation, mileage, and vertical curve parameters; the elevation query interface supports positioning and querying the line elevation of any mileage; the longitudinal section column editing interface supports customization and editing of the style and column parameters of standard longitudinal section drawing; the longitudinal section labeling interface supports editing and customizing the labeling of the auxiliary lines of the longitudinal section. This system provides a corresponding line longitudinal section design tool set for the longitudinal section slope entity object. The file I / O toolset includes 6 tools such as saving and importing files of specified formats such as slope diagrams, vertical curves, and ground lines; the style attribute toolset includes 2 tools such as ruler setting and parameter modification; the slope initialization toolset includes 2 tools such as slope initialization and simple grid drawing; the slope change point editing toolset includes 4 direct slope change point operation tools such as adding, deleting, and modifying slope change points, and vertical curve projection, as well as 3 indirect slope change point operation tools such as slope modification, combined slope adjustment, and moving slope sections; the fill and cut height query toolset includes 4 tools such as marking the lowest point, checking the fill and cut height, calculating the fill and cut height, and marking the elevation point; the longitudinal section drawing toolset includes 1 tool for standard longitudinal section drawing; the longitudinal section marking toolset includes 5 tools such as longitudinal section marking update, clearing, and modification operations, the lowest point column target, and pump station height marking.

[0049] like Figure 7As shown in the figure, this system completes the drawing design work of plane and longitudinal section through the plane and longitudinal drawing layout output unit. The specific steps are to use the three types of customized entity objects customized by the system, namely the plane standard drawing frame, the longitudinal section drawing frame, and the plane folding drawing frame, to design the frame layout, and then use the layout to generate all drawings with one click. The system provides corresponding tool sets around the three types of drawing frames. Based on the design habits of plane and longitudinal section drawing, this system derives from the entity base class objects of the AutoCAD platform and constructs three types of customized entity objects, namely the plane standard drawing frame, the longitudinal section drawing frame, and the plane folding drawing frame. The plane standard drawing frame object contains the plane drawing frame information such as the length and width of the plane rectangular drawing frame, the base point of the lower right corner of the drawing frame, the proportion of the drawing frame display port, and the corresponding information editing interface. The longitudinal section drawing frame object contains the length and width of the four rectangular drawing frame viewports and the spacing between them, the base point of the lower right corner of the four drawing frames, the proportion of the drawing frame display port, and the longitudinal section drawing frame information, as well as the corresponding information editing interface. The plane folding drawing frame object contains the map height information in the plane folding drawing frame, the polyline folding point information of the frame axis, the frame display port ratio and other folding drawing frame information as well as the corresponding information editing interface. This system is centered around the plane standard drawing frame custom entity object. The system provides five tools such as plane frame creation, modification, plane frame file saving and importing, and one-click plane frame layout generation; around the longitudinal section drawing frame custom entity object, the system provides five tools such as longitudinal section frame creation, modification, plane frame file saving and importing, and one-click longitudinal section frame layout generation; around the plane folding drawing frame custom entity object, the system provides seven tools such as creating and modifying plane frames, adding and deleting folding points, saving and importing plane folding drawing frame files, and one-click plane folding drawing frame layout folding.

[0050] like Figure 8 As shown, this system uses the line data table output module to complete the table output of line design results. Based on the line plan management data model, this system extracts and processes the data and then outputs it. It can be output through Office or WPS office software text tables, or CAD graphic tables. 15 types of table formats are designed according to the application scenarios of line output. Among them, based on the line plan management data model, the system provides designers with a set of 10 line results table output tools. Among them, the horizontal curve table, horizontal curve statistics table, pile-by-pile table, vertical curve table, and slope statistics table all support single-line and double-line table output, and the line spacing table, line station feature table, control point results table, and coordinate results table are all output for the overall line plan.

[0060] In summary, this system and method can establish a line scheme management mechanism around the design of rail transit lines, and label the technical standards, line design data, and interface data with other disciplines. The entire mechanism runs through the entire design process. When designers operate lines, stations, and other entities with tags, they will query the relationship between objects through the scheme management mechanism, and complete a series of operations such as adding, deleting, modifying, updating, querying, and editing. The corresponding operation tool set will interact with the scheme management mechanism to obtain the logical relationship between objects. At the same time, the system forms a data package based on a single scheme as a unit, manages and interacts around the scheme from the perspective of the timeline, and meets the needs of repeated iterations of the scheme during the design process. Compared with other methods and systems at this stage, this method and system not only optimizes the line design process and tools, but also proposes a solution for the data management iteration of the design scheme. From the perspective of the entire design cycle, it greatly improves the work efficiency and accuracy of rail transit line design.
