Abstract
Description
Technical Field
[0001] This invention relates to the field of railway signaling technology, and specifically to a method and system for digitizing railway signaling circuits. Background Technology
[0002] The railway signaling system, a specialization within railway signaling, is a control system that ensures railway traffic safety and improves transportation efficiency. It includes dispatching and command systems, interlocking systems, train control systems, block systems, and power supply systems. Unlike civil engineering and other specializations that focus on spatial scenarios, railway signaling involves more logical connections. The functions of each system are mainly realized through circuits composed of equipment and lines.
[0003] With the development of modern technology, railway signaling is gradually moving towards electronic and digitalization. However, the degree of digitization of railway signaling circuits is still relatively low, and the methods of digitization are still relatively simple, generally using a non-fully digital approach of "standard circuit diagrams + dynamic terminals".
[0004] Therefore, a method for fully digitizing railway signaling circuits is proposed and applied to the fields of intelligent design, construction, and full life-cycle management of railway signaling systems, which can promote the digital development of railway signaling systems. Summary of the Invention
[0005] The purpose of this invention is to provide a method and system for digitizing railway signal circuits, in order to solve the problem that there are currently only incomplete methods for digitizing railway signal circuits and a lack of fully digitized methods.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0007] A method for digitizing railway signaling circuits, the method comprising:
[0008] Organize various standard circuit diagrams related to railway signaling, create a dictionary of standard circuit diagram names, and digitize the names of standard circuit diagrams;
[0009] Organize the cabinets and combinations related to railway signaling, create cabinet and combination dictionaries, and digitize cabinet and combination information;
[0010] Based on standard circuit diagrams, relevant components and equipment are categorized and organized, a component and equipment dictionary is created, and component and equipment information is digitized.
[0011] Using the standard circuit diagram to be digitized as the object, and using all the components and devices in the standard circuit diagram as the rows and columns of the matrix, a corresponding directed graph matrix is established;

[0019] Create a dictionary of components and devices for querying and managing components and devices involved in standard circuit diagrams.
[0020] Furthermore, taking the standard circuit diagram to be digitized as the object, and using all components and devices in the standard circuit diagram as the rows and columns of a matrix, a corresponding directed graph matrix is established, including:
[0021] Each row and column of the directed graph matrix contains the name of its elements;
[0022] A directed graph matrix is a square matrix with an equal number of rows and columns.
[0023] The terminals and side wiring terminals of components and equipment are arranged as rows and columns of a matrix, and the order of the terminals and side wiring terminals of components and equipment in the rows and columns is the same.
[0024] Furthermore, the nodes in a standard circuit diagram are the same as the vertices of a directed graph matrix.
[0025] Furthermore, under normal circumstances, the connection relationship between nodes is defined as 1;
[0026] In the abnormal state, the connection relationship between nodes is defined as -1;
[0027] A value with no connection under both normal and abnormal conditions is defined as 0.
[0028] Further, calculate and input the corresponding matrix, including:

[0050] This embodiment provides a method for digitizing railway signaling circuits. The steps can be executed in a computer system, such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps can be executed in a different order. Figure 1 The methods include:
[0051] S1: Organize various standard circuit diagrams related to railway signaling, create a dictionary of standard circuit diagram names, and digitize the names of standard circuit diagrams.

For example, the first group of contacts of a JWXC-1700 relay is defined as three nodes: 11, 12, and 13. The connection between nodes under normal conditions is defined as 1; the connection between nodes under abnormal conditions is defined as -1 (applicable to components like relays that have multiple states); and the connection with no connection under both normal and abnormal conditions is defined as 0.
[0074] S501: Divide a standard circuit diagram with complete loops that are not directly related to each other into independent circuit units;
[0075] S502: Defines a template-type standard circuit diagram as a circuit;
[0076] In a template-type standard circuit diagram, the circuit form and connection relationship remain unchanged, while the combination position, cabinet and wiring terminals are different.
[0077] S503: Traverse all circuit units and circuits, define the terminals of all components and devices and the terminals of side wiring as vertices, and define the circuit matrix as rows and columns respectively;
[0078] S504: Starting from the positive terminal of the power supply (which can be assumed if there is no power supply), following the direction of the current as the path, and following the method of a directed graph, until a loop is formed, determine the connection relationship of each node on the path one by one, and store the result in the directed graph matrix D.
[0079] Repeat step S504 until all connections in the circuit have been traversed and saved.

[0082] As shown in the diagram, the arrows indicate the direction of the current. A directed graph is defined according to the current direction. Starting from the positive terminal of the power supply, the path follows the current direction until a loop is formed. Traverse all nodes in the circuit diagram to determine the vertices of the matrix: XJZ220, RD1-1, RD1-2, DJ-5, DJ-6, 15-701-15, DXJ-31, DXJ-32, DXJ-33, 15-701-1, 15-701-2, 1F-301-1, 1F-301-2, D1-B, D1-A, D1-BAH, 1F-301-3, 15-701-3, RD2-2, RD2-1, XJF220. Determine the connection relationship of each node on the path one by one. Under normal conditions, a connection between nodes is defined as "1", under abnormal conditions, a connection between nodes is defined as "-1", and a node with no connection in either state is defined as "0". Store the results in a matrix, as shown in the diagram. Figure 4 As shown.
[0083] Example 3:
[0084] This embodiment provides a railway signaling circuit digitization system, which is used to implement the method described in Embodiment 1, including:
[0085] The first creation module is used to sort out various standard circuit diagrams related to railway signaling, create a dictionary of standard circuit diagram names, and digitize the names of standard circuit diagrams, corresponding to S1 in Implementation 1.
[0086] The second creation module is used to organize the cabinets and combinations related to railway signaling, create cabinet dictionary tables and combination dictionary tables, and digitize the cabinet information and combination information, corresponding to S2 in Implementation 1.
[0087] The third creation module is used to classify and organize relevant components and equipment according to standard circuit diagrams, create a component and equipment dictionary, and digitize component and equipment information, corresponding to S3 in Example 1.
[0088] The matrix building module is used to build a corresponding directed graph matrix with the standard circuit diagram to be digitized as the object and all components and devices in the standard circuit diagram as vertices, corresponding to S4 in Example 1;
[0089] The traversal module is used to traverse all nodes and connections in each standard circuit diagram to be digitized, calculate and input the corresponding matrix, corresponding to S5 in Example 1.
[0090] With digital circuit matrices, railway signaling circuit design no longer relies on specific software platforms such as AutoCAD, but is entirely based on data. In engineering design, it can be used for dynamic drawing of circuit diagrams for each system, automatic generation of wiring diagrams, automatic configuration of BIM project attributes (such as connection relationships), and data flow path querying during circuit simulation, based on the specific engineering conditions of each work site (station, relay station, line junction, etc.), greatly improving accuracy and design efficiency.
