Description

Technical Field

[0001] This disclosure relates to the field of rail transit technology, and in particular to a verification method, apparatus and system for ATS operating lines based on a graphical interface. Background Technology

[0002] CBTC (Continuous Train Control) systems utilize communication networks to achieve two-way communication between trains and ground equipment, real-time reporting of train positions, and calculation of movement authorizations, replacing fixed track block systems for train operation control. CBTC can be used to implement both Fixed Automatic Block System (CBTC-FAS) and Moving Automatic Block System (CBTC-MAS). Key technologies in CBTC applications include two-way wireless communication systems, train positioning technology, and train integrity detection.

[0003] In urban rail transit CBTC systems, automated train operation is achieved by setting train operation routes. These routes determine the fixed turnaround sections where trains perform their transport tasks, and therefore must be verified before the subway officially begins operation.

[0004] However, under current technology, the method for verifying train operation routes involves building a simulated train on a test platform, assigning the train operation route to be verified, and letting it run along the predetermined route to its destination. Since urban rail transit CBTC systems involve numerous stations, the ATS (Automatic Train Management System) needs to program hundreds or even thousands of operation lines. Clearly, verifying the correctness of train operation routes using traditional methods is extremely time-consuming. Furthermore, problems that only surface under specific conditions often cannot be detected using traditional verification methods, leading to the unfortunate consequence of problems persisting even after the project is operational.

[0019] As an optional implementation of this application, optionally, based on the content of the train operation route document, a corresponding station layout graphic file is compiled, and the compiled station layout graphic file is configured on the ATS software platform, further including:

[0020] Preset station map annotation information;

[0022] An automated script containing the station map graphic file is configured on the ATS software platform to prepare for generating the station map of the train operation route file.

This method can convert invisible train operation routes into visible station layout diagrams, providing a method for verifying the accuracy of train operation routes in an intuitive graphical mode. It eliminates the need for extensive simulation testing; simply comparing the graphically generated train operation routes with the design drawings achieves the verification purpose, showing promising prospects for verifying train operation routes.

[0045] Compared to traditional verification methods, this invention provides a more comprehensive view of problems existing on the operating line. For example, when using traditional testing methods, testers cannot verify whether a stop station is actually set up. This is because the actual performance of a stop station and a station without a stop is the same; the difference can only be distinguished under specific fault scenarios. However, when using the verification method of this invention, it is possible to directly distinguish whether a station is not present on the operating line or has stopped in a graphical display, thus improving the accuracy of the test.

[0053] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0054] Example 1

[0055] This invention provides a verification method for verifying the accuracy of train operation lines in an intuitive graphical mode by converting invisible train operation routes into visible station diagrams.

[0056] in:

[0057] The train operation route file is a preset train operation route file in the CBTC system, i.e., a built-in operation line;

[0058] The train route design drawings are the original design documents for train operation routes.

[0059] The purpose of this technology is to add a script to the train operation route file during compilation on the ATS software platform of the urban rail transit CBTC project, automatically generate the corresponding operation line graphic file, and compare the operation line graphic file with the train operation line design drawing to quickly and intuitively verify the correctness of the preset train operation route.

[0060] like Figure 1 As shown, this application proposes a verification method for ATS operation lines based on a graphical interface, comprising the following steps:

[0061] S1. Read train operation route documents;

[0062] The train operation route file is configured on the ATS software platform of the urban rail transit CBTC project. Here, when compiling the ATS software in the urban rail transit CBTC system, the preset train operation route file is read through the compilation script.

[0063] As an optional implementation of this application, the step of reading the preset train operation route file may include:

[0064] Preset compilation environment; the compilation environment is the environment in which the ATS software is compiled, so we will not set up and create a compilation environment separately here;

[0065] Write automation scripts in the compilation environment; in the compilation environment, write automation scripts (compilation scripts) that can read data, and read the train's built-in operating lines by writing automation scripts;

[0066] The automated script reads a preset train operation route file. Specifically, it uses a compiled automated script to read the preset train operation route file. After obtaining the preset train operation route file, the script can draw the corresponding station layout diagram based on the content written in the file. Once the compiled script is added to the ATS software in the urban rail transit CBTC system, execution will produce the corresponding graphic representation.

[0067] However, in order to compare the route information, such as the origin station, destination station, and stopping platform, with the train operation route design drawings, it is also necessary to convert the built-in operation route file into a graphical interface in the compilation script. This ensures that the station map obtained after the train operation route file is converted and executed by the compilation script also contains route information. This facilitates quick and intuitive verification of the correctness of the preset train operation route when comparing the station map of the train operation route file with the train operation route design drawings.

[0068] S2. Based on the content of the train operation route document, compile the corresponding station map graphic file and configure the compiled station map graphic file on the ATS software platform;

[0069] This step mainly involves generating annotation information and drawing corresponding station maps (with route information) based on the route information contained in the train operation route documents.

[0070] As an optional implementation of this application, optionally, based on the content of the train operation route document, a corresponding station layout graphic file is compiled, and the compiled station layout graphic file is configured on the ATS software platform, including:

[0071] The train operation route file is obtained through an automated script; see the implementation steps above for reading the built-in operation line through an automated script.

[0072] The train operation route file is parsed to obtain the station map information of the train operation route file; the user parses the read train operation route file according to the specified file format to obtain station map information containing various route information, such as origin station, destination station, stopping platform, skip-stop platform, ISP point, route direction, etc.

[0073] Based on the station layout information, draw a station layout corresponding to the train operation route document.

[0074] First, the compilation script draws the corresponding station map based on the route content contained in the preset train operation route file; second, the compilation script marks the corresponding information in each operation route one by one based on the operation station information, etc.

[0075] As an optional implementation of this application, optionally, based on the content of the train operation route document, a corresponding station layout graphic file is compiled, and the compiled station layout graphic file is configured on the ATS software platform, further including:

[0076] Preset station map annotation information; The station map annotation information will be set according to the content written in the preset train operation route file, such as the various starting stations, ending stations, stopping platforms, skip-stop platforms, ISP points, and route directions that need to be annotated on the station map;

[0077] The station map annotation information is annotated on the station map in chronological order to obtain a station map graphic file corresponding to the train operation route file; in the compilation script, the above annotation information is annotated on the station map to obtain a station map graphic file with annotation information; after the station map graphic file is executed by the script, a visualized annotated station map graphic can be obtained;

[0078] An automated script containing the station map graphic file is configured on the ATS software platform to prepare for generating the station map of the train operation route file.

[0079] When compiling the ATS software platform for urban rail transit CBTC projects, this automation script can be added, and the corresponding running line graphic file can be automatically generated after compilation.

[0080] S3. Perform graphic conversion to obtain the running line graphic file of the station map graphic file;

[0081] The automation script contains station map graphic files with annotation information. Adding this to the compilation environment of the ATS software platform and running it will generate the automatically produced running line graphic file, such as... Figure 2 As shown in the figure (the representation of each station is the industry identifier of the rail transit department or user, which will not be elaborated in this embodiment).

[0082] S4. Compare the graphic file of the running line with the design drawings of the train's running line to complete the ATS running line verification of the train.

[0083] like Figure 3 The train's route design drawings shown will be compiled and displayed on the Urban Rail Transit CBTC project ATS software platform after they are run.

[0084] In this embodiment, the compilation script for running the line drawing file is added to the compilation time node of the design drawing to facilitate synchronous visualization display. Figure 2 The running line chart shown and Figure 3 The train route design diagram shown is convenient for comparison according to time sequence.

[0085] The developed automation script converts the built-in train operation line files into a graphical interface. This script is added during the compilation process on the ATS software platform for urban rail transit CBTC projects, and the corresponding operation line graphical files are automatically generated upon completion. Station maps containing all preset train operation route information can be compared with design drawings to achieve verification. Designers or rail transit operators can perform this comparison to quickly and intuitively verify the correctness of the preset train operation routes.

[0086] In contrast to traditional verification methods, this invention can more intuitively display the details of the preset train operation routes, eliminating the need for extensive simulation experiments and reducing the testing time from several days to just a few hours.

[0087] Compared to traditional verification methods, this invention provides a more comprehensive view of problems existing on the operating line. For example, when using traditional testing methods, testers cannot verify whether a stop station is actually set up. This is because the actual performance of a stop station and a station without a stop is the same; the difference can only be distinguished under specific fault scenarios. However, when using the verification method of this invention, it is possible to directly distinguish whether a station is not present on the operating line or has stopped in a graphical display, thus improving the accuracy of the test.

[0088] It should be noted that although the compilation environment of ATS software is used as an example to illustrate the graphical drawing and compilation process of the above automated script, those skilled in the art will understand that this disclosure is not limited to this.
