Description

Technical Field

[0001] This invention belongs to the field of railway signal equipment testing technology, and in particular relates to a railway signal interlocking relationship verification system and method. Background Technology

[0002] Signal interlocking is a crucial technical measure to ensure safe train operation at stations, and a tight interlocking relationship is fundamental to this safety. Signal interlocking testing is an important aspect of ensuring the safety and technical management of signal equipment, and it is integrated throughout the entire process of signal equipment design, construction, operation, and maintenance. It plays an irreplaceable role in ensuring the correctness of interlocking relationships.

[0003] In their daily maintenance, railway signaling sections focus on participating in the annual signal interlocking test. The test process requires traversing the test route line by line according to the interlocking table and recording the test results, which is a lot of work. At the same time, since the interlocking test must be carried out within the track maintenance window, and the operation time within the track maintenance window is short, the existing annual interlocking test is not very operable and is prone to deviation, thus posing safety hazards. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a railway signal interlocking relationship verification system and method to reduce the workload of annual interlocking tests and prevent errors caused by human factors.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A railway signal interlocking relationship verification system includes a station route identification device, an interlocking test operation terminal, and a railway signal interlocking relationship verification management system;

[0007] The station route identification device is connected to the station repeater terminal signal monitored by the microcomputer, the station route identification device is connected to the railway signal interlocking relationship verification and management system, and the railway signal interlocking relationship verification and management system is connected to the interlocking test operation terminal bidirectionally.

[0008] The station route identification device is used to collect route information processed by the station in real time by identifying the station map on a real-time VGA split screen, and transmit the route information to the railway signal interlocking relationship verification and management system in real time.

[0009] The railway signal interlocking relationship verification and management system is used to collect route information processed by the station, and to decompose the station interlocking route table and generate the interlocking test checklist based on the route information. At the same time, it automatically compares the collected manual test results with the automatic recognition results to determine whether the test operation has been completed.

[0010] The interlocking test operation terminal is used to generate test cases based on the interlocking test checklist transmitted from the railway signal interlocking relationship verification management system, display the test cases to the staff currently holding the interlocking test operation terminal, collect the results of manual tests, and then upload the results of manual tests to the railway signal interlocking relationship verification management system.

[0011] Furthermore, the railway signal interlocking relationship verification and management system collects route information processed by the station in the following specific way: it collects and stores the route information processed by the station identified by the station route identification device in real time through the information channel of the signal connection between the railway signal interlocking relationship verification and management system and the station route identification device;

[0012] The decomposition process of the station interlocking route table is as follows: by adding and importing the basic data of the station interlocking routes, the interlocking routes of each station are established, thereby generating the station interlocking route table;

[0013] The process of generating the interlocking test checklist is as follows: The railway signal interlocking relationship verification management system analyzes the historical route information processed after the last interlocking test, compares it with the station interlocking route table, and filters out the route information that has not been processed to form the current interlocking test checklist.

[0014] Furthermore, the station route identification device and the station repeater terminal monitored by the microcomputer are connected via VGA split screen signal connection.

[0015] Furthermore, the station route identification device is connected to the railway signal interlocking relationship verification and management system via an information channel, and the railway signal interlocking relationship verification and management system is connected to the interlocking test operation terminal via a two-way signal via an information channel.

[0018] Furthermore, the station route identification device includes a VGA signal acquisition module, a preprocessing module, an analysis module, a communication module, and a station route image recognition module;

[0019] The VGA signal acquisition module, preprocessing module, station route image recognition module, analysis module, and communication module are sequentially connected by signals, wherein:

[0020] The VGA signal acquisition module is used to acquire real-time VGA split-screen site diagrams.

[0021] The preprocessing module is used to perform image preprocessing on the real-time VGA split-screen site map;

[0022] The station route image recognition module is used to recognize the pre-processed real-time VGA split-screen station map and identify the names and corresponding statuses of signals, switches, and track circuits as recognition results.

[0023] The analysis module is used to combine the station interlocking route table and the identification results to analyze the currently processed route information through comparison.

[0024] The communication module is used to send the currently processed route information to the railway signal interlocking relationship verification and management system.

[0025] A method for verifying railway signal interlocking relationships using a railway signal interlocking relationship verification system, the method comprising the following steps:

[0027] Step 2: Establish a station route identification device based on image recognition to collect route information processed by the station in real time, and transmit the route information processed by the station to the railway signal interlocking relationship verification and management system.

[0028] Step 3: Establish an interlocking test operation terminal for on-site interlocking testing and recording, which is used to receive the interlocking test checklist generated by the railway signal interlocking relationship verification management system, and generate test cases for on-site interlocking tests;

[0029] Step 4: Based on the test cases of the on-site interlocking test generated by the interlocking test operation terminal in Step 3, the on-site operators will perform manual checks of the interlocking test in sequence to obtain the manual test results. At the same time, the station route identification device will identify and automatically record the results of the test case execution, thereby obtaining the automatic identification results, and upload the automatic identification results to the railway signal interlocking relationship verification management system.

[0030] Step 5: The operators upload the recorded manual test results to the railway signal interlocking relationship verification and management system through the interlocking test operation terminal;

[0031] Step Six: The railway signal interlocking relationship verification and management system automatically compares the results of manual tests with the results of automatic identification to determine whether the test operation is completed. If the comparison results are consistent, the test operation ends; otherwise, steps three to five are repeated until all interlocking tests are completed.
