Description

Technical Field

[0001] This application relates to the field of railway signal control technology, and in particular to a temporary dispatch receiving and conversion device. Background Technology

[0002] LKJ: Train operation monitoring and recording device.

[0003] Wireless transponder: A device used to establish LKJ data vehicle-to-ground communication.

[0004] In railway transportation, the accurate and timely execution of temporary speed limit dispatch orders is crucial to ensuring train operation safety. Currently, temporary speed limit dispatch orders primarily rely on manual transmission and execution, which has significant drawbacks:

[0005] LKJ train control data gap: LKJ cannot directly obtain temporary speed limit dispatch orders issued by the ground CTC / TDCS system. Drivers need to be notified manually by telephone or radio at the station, and then manually control the train. This poses a risk of human error, and LKJ cannot automatically execute speed limit control.

[0006] Data format incompatibility: The dispatch commands issued by the CTC / TDCS system are in text format, which is not a vehicle control data format that LKJ can recognize. The commands need to be manually converted into LKJ temporary speed limit data and written through the IC card. This cannot handle commands issued temporarily during operation, resulting in low efficiency and a high risk of errors.

[0007] Insufficient transmission reliability: It relies on a single CIR vehicle radio channel to receive commands, without redundancy, which may lead to command omissions due to communication failures, and the ground cannot obtain acknowledgment information to verify the execution status.

[0008] Poor adaptability to cross-border operations: In cross-border scenarios such as the China-Laos Railway, the existing LKJ system only supports Chinese interface and Beijing time, which Lao train attendants cannot operate directly, and the dual time zone control requirements cannot be met, which limits the automated train control capabilities of cross-border trains. Utility Model Content

[0009] To improve the efficiency of LKJ in receiving and executing temporary speed limit scheduling commands, this application provides a temporary command receiving and conversion device.

[0010] The temporary dispatch command receiving and conversion device provided in this application adopts the following technical solution: it includes an LKJ human-machine interaction unit, a dual-channel redundant receiving module that is communicatively connected to the CIR vehicle radio and the wireless switching device, the dual-channel redundant receiving module adopts a "two-out-of-one" mechanism to verify command consistency, the dual-channel redundant receiving module is communicatively connected to the dispatch command parsing module, the dispatch command parsing module is communicatively connected to the LKJ data conversion module, and the LKJ data conversion module is communicatively connected to the wireless switching device of the LKJ human-machine interaction unit, forming a structure in which the dual-channel redundant receiving module transmits the temporary dispatch commands received from the CIR vehicle radio or the wireless switching device to the dispatch command parsing module, the dispatch command parsing module extracts the setting elements and translates them into LKJ vehicle control parameters in combination with the LKJ vehicle basic data, and sends the dispatch commands to the LKJ human-machine interaction unit through the wireless switching device.

[0011] Optionally, the setting elements include dispatch command number, speed limit value, start time, end time, line name and station name, and the train control parameters include station number, line number and mileage marker.

[0012] Optionally, a dual-language, dual-clock control module is also included. This module comprises a screen display supporting Chinese / Lao language interface switching, and a clock unit for displaying and switching between Beijing time and Lao time. The buttons and voice prompts on the screen display automatically switch according to the interface language, and the clock unit supports manual time switching based on the train's location.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The dual-channel redundant receiving module transmits the temporary dispatch commands received from the CIR vehicle radio or wireless switching device to the dispatch command parsing module. The dispatch command parsing module extracts the setting elements and translates them into LKJ vehicle control parameters in combination with the LKJ vehicle basic data. The dispatch command is then sent to the LKJ human-machine interaction unit through the wireless switching device, ensuring the timely reception of temporary dispatch commands, improving the real-time performance and accuracy of speed limit control, and reducing the risk of accidents.

[0015] 2. The dual-channel redundancy design ensures that no commands are missed and solves the problem of single-channel communication failure; it supports command feedback between the ground and the vehicle to verify the execution status and improve transportation safety.

[0016] 3. The dual-language interface and dual-clock control meet the needs of cross-border scenarios such as the China-Laos Railway, facilitate collaborative operation between Chinese and Lao train crews, and improve the efficiency of cross-border train operation;

[0017] 4. The key modules of the screen display adopt a redundant design, which supports rapid fault switching and achieves a safety integrity level of SIL2, ensuring stable operation of the equipment under complex working conditions and reducing maintenance costs. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses a temporary dispatch receiving and switching device. For example... Figure 1 and 2As shown, the system includes an LKJ human-machine interface unit 6, a dual-channel redundant receiving module 1 that is communicatively connected to the CIR vehicle-mounted radio 2 and the wireless transcoding device 3. The dual-channel redundant receiving module 1 uses a "two-out-of-one" mechanism to verify command consistency. The dual-channel redundant receiving module 1 is communicatively connected to the dispatch command parsing module 4, which in turn is communicatively connected to the LKJ data conversion module 5. The dispatch command parsing module 4 and the LKJ data conversion module 5 can perform regular expression parsing on the formatted temporary speed limit dispatch commands issued by the CTC / TDCS system to obtain key elements from the temporary speed limit dispatch command text information, including: dispatch command number, speed limit value, start time, end time, line name, station name, and train number. Combining LKJ onboard basic data, the system queries and translates the station number, line number, mileage, dispatch order number, and speed limit data elements required for LKJ temporary speed limit vehicle control by looking up station and line name lists. It can perform compliance checks on the LKJ temporary speed limit vehicle control data. The required data elements are then organized into LKJ temporary speed limit data according to the LKJ-specific format. This organized LKJ temporary speed limit data is then sent to the wireless conversion device 3. If an error is found during the regular expression parsing of the temporary speed limit dispatch order, the parsing process ends, and the result is sent to the wireless conversion device 3 to notify the ground. The LKJ data conversion module 5 is communicatively connected to the wireless conversion device 3 of the LKJ human-machine interaction unit 6. The wireless conversion device 3 is existing technology. The dual-channel redundant receiving module 1 transmits temporary dispatch commands received from the CIR vehicle-mounted radio 2 or the wireless transcoding device 3 to the dispatch command parsing module 4. The dispatch command parsing module 4 extracts setting elements and translates them into LKJ vehicle control parameters in conjunction with LKJ vehicle-mounted basic data. The dispatch command is then sent to the LKJ human-machine interface unit 6 via the wireless transcoding device 3. Setting elements include the dispatch command number, speed limit, start time, end time, line name, and station name. Vehicle control parameters include the station number, line number, and mileage marker.

[0024] In one embodiment, according to the accompanying drawings Figure 3 As shown, it also includes a dual-language, dual-clock control module. This module includes a screen display supporting Chinese / Lao language interface switching, and a clock unit for displaying and switching between Beijing time and Lao time. The screen display's buttons and voice prompts automatically switch according to the interface language, and the clock unit supports manual time switching based on the train's location.

[0025] The LKJ Human-Machine Interaction Unit 6 employs redundant design for key modules such as the button board, core board, power board, and IC card board. In the event of a monitor malfunction, a quick switch can be achieved via physical buttons on the front panel of the monitor, achieving a safety integrity level of SIL2.

[0026] The implementation principle of the temporary dispatch receiving and conversion device in this application embodiment is as follows: The device is installed in the locomotive control cabinet and connected to the wireless switching device 3, CIR vehicle-mounted radio 2, and LKJ human-machine interaction unit 6 via a dedicated cable to ensure smooth communication links between the devices. The screen display is an RYX-II type screen display that supports dual languages, imports the Lao LKJ dedicated terminology library, configures dual clock parameters with a 1-hour difference between Beijing time and Lao time, and completes the debugging of hardware redundancy modules.

[0027] The ground-based CTC / TDCS system simultaneously sends temporary speed limit dispatch commands to the vehicle-mounted device via the wireless swapping vehicle-to-ground channel and the CIR vehicle-mounted radio 2. The text device receives both commands, automatically verifies data consistency, and uses a "two-out-of-one" mechanism to ensure accuracy.

[0028] The dispatch command parser extracts key elements through regular expressions, the LKJ data converter organizes the parameters into the LKJ temporary speed limit data format, and writes it into the LKJ host through the wireless changing device 3. The LKJ automatically generates the speed limit curve and executes the control.

[0029] Lao flight attendants select the Lao language interface via buttons on the screen display, and the device automatically switches the displayed language and provides voice prompts.

[0030] Based on the train's location, the crew manually switched the control time to Lao time, which is one hour behind Beijing time. LKJ then performed the reveal control based on Lao time to ensure that time-related records and controls accurately matched the local time zone.

[0031] If the wireless switching channel fails, the device automatically switches to CIR vehicle radio channel 2 to receive commands; if the screen display fails to switch to a single mode, it switches to a redundant module via physical buttons to ensure continuous vehicle control.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
