Description

Technical Field

[0001] The invention relates to a train signal control system, and in particular to an automatic judgment and identification method for the influence range of system design changes on ATC. Background Art

[0002] In the process of urban rail project application design activities, system design is the upper-level design of the train automatic control subsystem (ATC), computer interlocking subsystem (CI), train automatic monitoring subsystem (ATS), maintenance monitoring support subsystem (MSS), and data communication transmission subsystem (DCS), such as Figure 1 As shown in the figure, the output system database (SYDB) and train real-time time parameters (RTI) are the top-level inputs of the application design of each subsystem and are the basis for realizing the complete functions of a subway line.

[0003] Whenever a project design baseline is released or the system is upgraded, ATC needs to fully identify the changes in SYDB and RTI and determine the impact on ATC during the design activities, and then carry out subsequent activities accordingly. For SYDB and RTI, which have huge data volumes and complex contents, current designers only rely on manual identification and judgment, and finally obtain the results of the changes affecting ATC. This is not only time-consuming and laborious, but also requires high technical accumulation and high work responsibility of personnel. Since this process is a safety activity process, once there are subjective and objective factors such as negligence, misjudgment, and empiricism, potential driving safety hazards will occur.

[0004] Therefore, how to implement an automated method that can quickly and accurately identify changes in SYDB and RTI and determine the impact to improve work efficiency and reduce security risks has become a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a method for automatically judging and identifying the impact range of system design changes on ATC.

[0018] As a preferred technical solution, the custom comparison file UserConfig is an optional Excel file, which allows ATC designers to customize the content to be judged and identified according to actual needs.

[0019] As a preferred technical solution, the user-defined comparison file UserConfig includes two forms, VS and TAPIP, each of which defines the content to be judged, value-taking rules, value-taking sources, value-taking algorithms, value-taking precision and remarks information content.

[0020] As a preferred technical solution, in step S107, since SYDB is an XML file and RTI is an Excel file, Xpath path function expression and NPOI are used to automatically parse and extract SYDB and RTI contents respectively, and combined with VS or TPAIP value rules, the change scope is automatically determined.

The final output result is in the "Judgment Result" column of the system design change identification option area, and is displayed in red, green, and gray, respectively indicating that the system design has been changed, the system design has not been changed, and it does not participate in the judgment and identification.

[0022] As a preferred technical solution, in the steps S105-S108, a rich error reporting of user error operation or input error information is provided, and the calculation log is printed in real time in the background;

[0023] The method provides a visual judgment principle for each result, and provides a judgment rule index comparison table for VS and TAPIP values.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] The present invention is a method for automatically judging and identifying the impact range of system design changes on ATC, which fills the gap in automatic change identification of system design. It can rely on computer programs to quickly and accurately judge whether the safety data (VS) and trackside typical train parameters (TAPIP) of ATC need to be changed, which not only improves work efficiency, but also improves work quality, reduces human errors, and further ensures the accuracy of the safety activity process, thereby ensuring on-site driving safety.

[0041] like Figure 1 and Figure 2 As shown, a method for automatically determining and identifying the impact range of system design changes on ATC includes the following steps:

[0042] Step S101, the system design generates a new system database SYDB and train real-time parameters RTI according to the actual needs of the project;

[0043] Step S102: To meet the universality goals of different urban rail projects, ATC designers need to edit the project configuration file ProjectConfig;

[0044] Step S103, in order to meet the universality goals of different baselines, the ATC designer edits the custom comparison file UserConfig as needed;

[0045] Step S104, in the automation tool, select the change identification option of VS or TAPIP;

[0046] Step S105, loading the current version and the previous version of SYDB;

[0047] Step S106, loading the current version and the previous version of RTI;

[0048] Step S107, automatically determining the impact range of the change of VS or TAPIP according to the identification item selected in step S104;

[0049] Step S108, outputting the final result in an intuitive visual interface.

[0050] The project configuration file ProjectConfig is the basic configuration required for each subway line, such as Figure 3 As shown, it includes two major components: basic project properties and TAPIP default properties. In theory, this configuration only needs to be done once during the entire life cycle of each project.

[0051] The vehicle's minimum deceleration, vehicle's maximum acceleration, vehicle's maximum speed, vehicle's maximum wheel diameter, and vehicle's minimum wheel diameter in the basic attributes of the project are based on vehicle manufacturing parameters provided by the vehicle manufacturer.

[0052] The custom comparison file UserConfig is an optional Excel file. Due to the continuous iterative update of the baseline, ATC designers are allowed to customize the content to be judged and identified according to actual needs, thereby meeting the universal requirements to the greatest extent.

[0053] The user-defined comparison file UserConfig includes two forms, VS and TAPIP, each of which defines information such as the content to be judged, value-taking rules, value-taking sources, value-taking algorithms, value-taking precision, and remarks.

[0054] In the step S107, since SYDB is an XML file and RTI is an Excel file, Xpath path function expression and NPOI are used to automatically parse and extract SYDB and RTI contents respectively, and combined with VS or TPAIP value rules, the change scope is automatically determined.

[0055] In the step S108, the visualization interface includes a menu bar area, a key basic configuration information display area for the project, a system design change identification option area, and an operation button area. The final output result is in the "Judgment Result" column of the system design change identification option area, and is displayed in red, green, and gray, respectively indicating that the system design has been changed (the ATC value is incorrect and needs to be updated), the system design has not been changed (the ATC value is accurate and does not need to be updated), and it does not participate in the judgment and identification.

[0056] In the steps S105-S108, a variety of error reports are provided for user erroneous operations or input erroneous information, and calculation logs are printed in real time in the background to facilitate debugging management and timely error correction.

[0057] The automation tool not only gives the final judgment result, but also provides a visual judgment principle for each result. In addition, it provides a judgment rule index comparison table for VS and TAPIP values ​​to prevent designers from ignoring or forgetting the design input principle after the automation process replaces manual work. Specific embodiments

[0059] Taking the first phase of Zhengzhou Urban Rail Transit Line 10 as an example, Figure 4 A flowchart for automatically determining and identifying the impact range of SYDB and RTI changes on ATC is designed for the system of the present invention. The specific steps are as follows:

[0060] Step S201: Open the automation tool and automatically load the configured project configuration file ProjectConfig, such as Figure 5 As shown, read according to the basic properties of the project and TAPIP default properties;

[0061] Step S202: The executable program automatically calculates the default wheel diameter in the background, such as Figure 6 As shown in the figure, the default wheel diameter is the basis for many VS and TAPIP parameter calculations, including the calculation of the maximum wheel diameter value and the minimum wheel diameter value. In the calculation window, real-time update and recalculation operations are allowed;

[0062] Step S203: Automatically create a VS form DataTableVS class, defining the impact factors, impact rules and calculation algorithms of SYDB and RTI on VS;

[0063] Step S204: automatically create the TPAIP form DataTableTAPIP class, and define the impact factors, impact rules and calculation algorithms of SYDB and RTI on TAPIP;

[0064] Step S205: Determine whether there is a custom comparison file to be added, if yes, go to step S206, if no, go directly to step S208;

[0065] Step S206: using NPOI technology to extract and parse the comparison file UserConfig, and read valid data according to the custom form;

[0066] Step S207: append the VS and TAPIP form data in the custom comparison file to the DataTableVS class in step S203 and the DataTableTAPIP class in step S204 respectively, and mark the custom added data with a light blue background in the main window interface to distinguish between default and custom data;

[0067] Step S208: Load the VS data of the project and display it in the "Current VS Value" column of the main window interface;

[0068] Step S209: Select VS or TAPIP to change the identification item according to actual needs;

[0069] Step S210: Load the current version SYDB and the previous version SYDB output by the system design. If there is no need to compare historical versions, only the current version SYDB may be loaded;

[0070] Step S211: Load the current version RTI and the previous version RTI output by the system design. If there is no need to compare the historical versions, only the current version RTI can be loaded;

[0071] Step S212: One-key identification, the final result is as follows Figure 7 As shown in the figure, the green items indicate that the system design has not been updated and the current ATC value is correct; the red items indicate that the system design has been updated and the current ATC value needs to be corrected and updated; the gray items indicate that there is no need to judge and identify the elements and ATC can be ignored; select a row of data in the main interface and double-click to pop up the judgment principle details window, such as Figure 8 As shown, it is convenient to design input queries.

[0072] In summary, the present invention provides a method for automatically judging and identifying the impact scope of system design changes on ATC. Based on the configuration file and using automated tools, the method allows ATC designers to quickly and accurately identify the change scope and impact results of the system design SYDB and RTI, thereby improving work efficiency and work quality, effectively reducing the probability of safety hazards caused by human failure escaping to the scene, and reducing safety risks.
