Description

Technical Field

[0001] The present application relates to the technical field of electrified railway contact network engineering design, and in particular to a contact network installation standard configuration method and system based on semantic features. Background Art

[0002] The catenary system is a special form of power supply line used by electrified railways to transmit electricity to electric locomotives. Supports, foundations, installation, and suspension are the basic functional subsystems of the catenary system. Catenary installation parameters are important basic parameters of the catenary system and form the core technical components of the catenary system. Catenary system design is divided into several aspects, including catenary layout, installation, quantity statistics, and specification writing. The standard configuration of catenary system installation is a necessary pre-design step for completing the catenary system design. Different catenary systems have different installation characteristics due to their operating environments (such as lines, bridges, and tunnels) and their own structures (positive positioning of contact suspensions, additional conductor shoulder brackets, etc.). Only by fully configuring installation technical standards can the specific catenary installation configuration be completed in a targeted manner according to the specific catenary system object in the specific layout design.

[0003] Until now, catenary design required the project manager to pre-configure a list of catenary installation parts. After completing the catenary layout, site designers would confirm the various parameters of each catenary device, compare them to the list of installation parts, and then determine the installation file drawing number. This method was only suitable for manual drawing and was not suitable for automated catenary drawing. Furthermore, the inconsistent numbering and naming conventions used for installation drawings in current catenary systems created significant difficulties in configuring installation drawings for catenary engineering designs.

Similar elements in different embodiments are numbered with associated similar elements.

[0035] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments.

Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0036] Before designing the overhead contact network for electrified railways, professional technical standards must be established. Installation drawings are a crucial component of these standards. In the past, a dedicated volume typically provided a list of component names for the project's installation drawings. Designers would then, during the actual overhead contact network design process, verify each parameter against the installation drawing component name list, then complete the design and count the number of parameters after design completion. This approach was insufficient for automated overhead contact network software. This application, however, extracts and configures key parameters for overhead contact network layout by semantically parsing the installation drawing file names, providing a technical standard foundation for automated overhead contact network layout.

[0037] The first embodiment of the present application provides a method for configuring contact network installation standards based on semantic features, which realizes the judgment and classification of installation drawing parameters by parsing the characteristic words of one or more installation drawing file names. The operation process meets the requirements of contact network digitalization and automated layout design. Figure 1 and Figure 2 Provide detailed explanation.

[0038] like Figure 1 As shown, in step S100, contact network installation drawing file names are obtained in batches.

[0039] The above steps specifically include:

[0040] Enter the installation drawing file names one by one or import them in batches.

[0041] Specifically, the front end inputs or imports a file name or a list of file names and issues a request.

[0042] like Figure 1 As shown, in step S200, the semantic information contained in the name of each installation drawing file is parsed according to a preset parsing rule, and the contact network layout technical characteristic parameters applicable to each installation drawing file are extracted.

[0043] The above steps specifically include matching the parsed semantic information with semantic feature words in a pre-created semantic feature table, which contains mappings between semantic feature words and technical characteristic parameters of the overhead contact network layout, and obtaining the technical characteristic parameters of the overhead contact network layout applicable to the installation drawing file based on the matching results. The technical characteristic parameters of the overhead contact network layout applicable to the installation drawing file include operating conditions, installation type, and installation parameters.

[0044] Specifically, the front end analyzes the file name, extracts the semantic features of the working conditions and applicable parameters of the installation diagram in the file, and converts these key information into the feature parameters of the file according to the rules in Table 1.

[0045] Classification of specific characteristics:

[0046] (1) Working conditions: catenary installation conditions such as inside tunnels, tunnels, bridges, pillars, steel columns, H-shaped (type) steel columns, and crossbars.

[0047] (2) Installation parameters: The parameter configuration of the installation itself, including the relative curve orientation (inside and outside), the applicable maximum curve radius, the type of compensation device, the tension parameters, etc.

[0048] Table 1 Semantic features and related descriptions

[0049]

[0050] Table 2 shows an example of file name parsing:

[0051] Table 2 Data analysis example

[0052]

[0053] like Figure 1 As shown, in step S300, the contact network layout technical characteristic parameters applicable to each extracted installation drawing file are associated with the basic information of the installation drawing file and stored in the database according to a preset storage format to provide an installation technical standard basis for the automatic layout of the contact network.

[0054] The above steps specifically include: encapsulating the contact network layout technical characteristic parameters applicable to the extracted installation drawing file and the basic information of the installation drawing file into json data; for a file name list consisting of multiple installation drawing file names, processing each file name in turn and parsing it, and encapsulating the parsed results of multiple file names into a json list.

[0055] Specifically, the front-end encapsulates the parsed semantic feature parameter data into json data and sends it to the back-end. Figure 3 As shown, for a list of multiple files, the system processes each file in turn, extracting the semantic features from the file name according to the rules in S200, and converting each file into a unique semantic feature parameter. The parameters of all files are encapsulated as a jsonlist and sent to the system backend.

[0056] Data preservation: The front-end passes the parsed data to the back-end, and the back-end service writes the relevant fields according to the JSON key and value.

[0057] The contact network installation standard configuration method based on semantic features provided in this application obtains the installation drawing file name (referred to as file name) by input or batch import when the front end is started, and parses and adapts the feature vocabulary of the installation file name according to the imported installation drawing number type (cantilever installation, additional conductor) and parameter feature requirements, and parses the contact network object features applicable to the installation drawing file ("straight line", "positive positioning"), etc., and stores them in the database together with other information of the installation drawing file.

[0058] Furthermore, the method also includes: in the contact network installation configuration link, loading the configured installation technical standards, analyzing the line and installation characteristic parameters of the project object, selecting the installation drawing number that meets the conditions, and realizing the automatic configuration of the installation.

[0059] When designing contact network projects, the installation technical standards determine the installation drawing numbers used for different project objects based on the project environment, project object characteristics, etc. For example, straight lines (line factors) and positive positioning (installation characteristics) use installation drawings numbered 1001-4. In the installation configuration phase, the configured installation technical standards are loaded, and by analyzing the line, installation and other characteristic parameters of the project object, the installation drawing number that meets the conditions is selected to achieve automated configuration of the installation.
