Description

Technical Field

[0001] This invention belongs to the field of rail transit, and specifically relates to a method and device for processing and confirming boarding prompts for railway wireless dispatching commands. Background Technology

[0002] Centralized Traffic Control (CTC) is an advanced railway traffic dispatching and command system that integrates computer, communication, and control technologies. It enables efficient, centralized, and remote control and monitoring of railway train operations and is widely used on both high-speed and conventional railway lines. When abnormal situations occur on railway lines, such as equipment failures, wind, rain, snow, earthquakes, extreme weather, or traffic accidents, train dispatchers should issue temporary speed limit orders and set train control speed limits according to regulations to ensure the safe operation of trains on the line.

[0003] Currently, in railway sections equipped with wireless dispatch command transmission systems, train dispatchers can directly issue written dispatch commands to drivers via the dispatch command terminal in the centralized dispatch system and the wireless transmission system, which drivers can then sign to acknowledge receipt. However, when train dispatchers fail to send wireless dispatch commands in a timely manner or drivers fail to sign for receipt promptly, trains may exceed speed limits in speed-restricted sections, leading to unsafe consequences. The dispatch command terminals currently used by train dispatchers cannot integrate with train operation plans to remind dispatchers of trains requiring wireless dispatch commands to pass through speed-restricted sections in the near future, necessitating manual monitoring, which presents certain safety risks and hidden dangers. In particular, when there are multiple long sections with speed limits within the dispatcher's jurisdiction, the workload for monitoring wireless dispatch commands is enormous and prone to errors. Furthermore, according to relevant regulations, train dispatchers need to record the sending and receiving of wireless dispatch commands for each train, currently all of which are recorded manually on paper, lacking relevant electronic records, making subsequent retrieval extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings by providing a method and device for processing and confirming train boarding prompts based on a centralized dispatching system for railway wireless dispatching commands. This method enables the processing, display, and storage of the issuance and receipt status of wireless dispatching commands for trains passing through speed-limited sections, thereby ensuring the timely issuance of wireless dispatching commands and the safe operation of trains, reducing the workload of train dispatchers, and improving their work efficiency.

[0005] To achieve the above objectives, the present invention provides a method for processing and confirming the onboarding of railway wireless dispatching commands, comprising: receiving a speed limit wireless dispatching command; extracting key speed limit information from the speed limit wireless dispatching command to determine the speed limit section; dynamically calculating, based on railway operation data, all trains affected by the speed limit passing through the speed limit section within a configured time, and prompting the train dispatcher to send the speed limit wireless dispatching command to the affected trains that are about to pass through the speed limit section; when the train dispatcher sends the speed limit wireless dispatching command, monitoring whether a driver's receipt of the speed limit wireless dispatching command is received, and / or determining whether the affected trains have passed through the speed limit section, to confirm the onboarding status of the speed limit wireless dispatching command.

[0006] Optionally, the railway operation data includes train operation plans, route sequences, static station data, station display information, dispatching commands, and train control speed limit operation events.

[0007] Optionally, by comparing the dispatch order number, speed limit section, and speed limit value in the speed limit wireless dispatch order sent by the train dispatcher and the driver's receipt of the speed limit wireless dispatch order, if the dispatch order number, speed limit section, and speed limit value are all the same, then the status of the speed limit wireless dispatch order on board is confirmed as "on board".

[0008] Optionally, the step of determining whether the train affected by the speed restriction has passed through the speed-restricted section includes: calculating the train position of the train affected by the speed restriction using the station display information; determining whether the train has passed through the speed-restricted section based on the train position; if the train position is greater than the end kilometer marker of the speed-restricted section when the line kilometer marker is increasing in the direction of train travel, or if the train position is less than the end kilometer marker of the speed-restricted section when the line kilometer marker is decreasing in the direction of train travel, then it is determined that the train affected by the speed restriction has passed through the speed-restricted section, and the status of the speed-restricted wireless dispatch command is confirmed as "passed through the speed-restricted section".

[0009] Optionally, receiving the rate-limiting wireless dispatch command specifically includes: receiving the dispatch command from the dispatch central system and checking the title and content of the dispatch command; if the title and / or content of the dispatch command contains the "rate-limiting" field, then the dispatch command is determined to be the rate-limiting wireless dispatch command.

[0010] Optionally, the key speed limit information in the speed limit wireless dispatch command can be extracted using regular expressions; the key speed limit information includes station name, line name, direction of operation, speed limit start and end kilometer markers, and speed limit value.

[0011] Optionally, the step of dynamically calculating all trains affected by speed restrictions that pass through the speed-restricted section within the configured time based on railway operation data specifically includes:

[0012] Initial calculation: Based on the first train operation plan, the first route sequence, the first static station data, and the first station representation information, calculate the train numbers affected by the speed limit that pass through the speed limit section within the configured time, and form the first train number sequence;

[0013] Update calculation: Based on the updated second train operation plan, second route sequence, second station indication information, the dispatching command, and the train control speed limit operation event, add or delete trains affected by speed limits in the Nth group of train sequences to form the N+1th group of train sequences, where N≥1.

[0014] Optionally, the update calculation for the trains affected by the speed limit in the Nth train sequence is repeated until a cancellation command for the speed limit wireless dispatch command is received or the train control speed limit is cancelled.

[0015] Optionally, the configuration time is greater than or equal to the duration from when the rate-limiting wireless dispatch command is sent to when it is acknowledged.

[0016] Optionally, the updated second train operation plan, second route sequence, second station indication information, dispatching command, and train control speed limit operation event are periodically updated based on the update information sent by the centralized dispatching system.

[0017] Optionally, the speed-limited section is located within a section of track, on the main line within a station, on a side line within a station, or on a section of track that crosses the main line within a station.

[0018] Optionally, the method further includes: when the signal to the speed-limited section is open, if the driver of the train affected by the speed limit that is about to pass through the speed-limited section has not signed the speed limit wireless dispatch command, the train dispatcher is prompted again.

[0019] Optionally, after the speed limit wireless dispatch command boarding prompt and confirmation ends, the relevant records of the speed limit wireless dispatch command boarding prompt and confirmation are saved.

[0020] This invention also provides a railway wireless dispatching command boarding prompt and confirmation processing device, comprising: a wireless dispatching auxiliary server module, which is communicatively connected to the dispatching centralized system, the wireless dispatching auxiliary server module being used to receive speed limit wireless dispatching commands to determine speed limit sections, and dynamically calculate, based on railway operation data, all speed-limited trains passing through the speed limit section within a configured time; and a wireless dispatching auxiliary terminal module, which is communicatively connected to the wireless dispatching auxiliary server module, the wireless dispatching auxiliary terminal module being used to receive and display the key speed limit information of the speed limit wireless dispatching command, and prompt the train dispatcher to send the speed limit wireless dispatching command to the speed-limited trains about to pass through the speed limit section, and prompt the train dispatcher to set up monitoring for the boarding of the speed limit wireless dispatching command; after the train dispatcher sends the speed limit wireless dispatching command, the wireless dispatching auxiliary server module confirms the boarding status of the speed limit wireless dispatching command by checking whether a driver's receipt of the speed limit wireless dispatching command has been received, and / or determining whether the speed-limited trains have passed through the speed limit section.

[0021] Optionally, the wireless dispatching auxiliary server module includes: a first communication processing unit, which is communicatively connected to the centralized dispatching system, for receiving railway operation data sent by the centralized dispatching system; the railway operation data includes train operation plans, route sequences, static station data, station indication information, dispatching commands, and train control speed limit operation events; a dispatching command processing unit, which is communicatively connected to the first communication processing unit, for receiving the dispatching command, determining whether the dispatching command is the speed limit wireless dispatching command, and calculating all speed-limited trains passing through the speed limit section within the configured time; a monitoring processing unit, which is communicatively connected to the first communication processing unit, for monitoring whether a driver's receipt of the speed limit wireless dispatching command is received, and / or determining whether the speed-limited trains have passed through the speed limit section; and a display status processing unit, which is communicatively connected to the first communication processing unit and the monitoring processing unit, for displaying the onboard status of the speed limit wireless dispatching command.

[0022] Optionally, the wireless dispatching auxiliary terminal module includes: a second communication processing unit, which is communicatively connected to the first communication processing unit, for receiving the speed limit wireless dispatching command, the train number affected by the speed limit, and the boarding status of the speed limit wireless dispatching command; and a display operation processing unit, which is communicatively connected to the second communication processing unit, for displaying the speed limit wireless dispatching command, the train number affected by the speed limit, and the boarding status of the speed limit wireless dispatching command.

[0023] Optionally, multiple threads are set between the monitoring processing unit, the display status processing unit, and the display operation processing unit to support simultaneous onboard prompts and confirmations for multiple speed-limiting wireless dispatch commands.

[0024] Compared with the prior art, the railway wireless dispatching command boarding prompt and confirmation processing method and device provided by the present invention have the following beneficial effects:

[0025] (1) By extracting the key information of the speed limit in the speed limit wireless dispatching command, the speed limit section can be determined. Combined with the dynamic monitoring of railway operation data and the calculation of the train numbers that need to be issued with the speed limit wireless dispatching command within the configuration time, the speed limit wireless dispatching command issuance and receipt status can be dynamically updated, displayed and stored. In this way, the train dispatcher can be prompted in real time to issue the wireless dispatching command to the train that is about to pass through the speed limit section, so as to ensure that the speed limit wireless dispatching command is issued in a timely manner and to ensure the safety of train operation.

[0026] (2) The device can be upgraded and expanded in the existing centralized dispatching system, which can meet the requirements of train dispatchers and has a wide range of applications; and the device makes the maximum use of the existing centralized dispatching system's software and hardware equipment and network transmission channels, which greatly reduces costs.

[0027] (3) Upgrading the issuance and receipt of speed limit wireless dispatching commands from the “human-to-human control” mode to the “human-machine control” mode can effectively improve the timeliness, reliability and security of sending and receiving speed limit wireless dispatching commands; at the same time, it significantly reduces the workload of train dispatchers in sending and confirming the receipt of wireless dispatching commands and improves the work efficiency of train dispatchers.

[0044] Train 400 Detailed Implementation

[0045] The technical solutions, structural features, achieved objectives, and effects of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0046] It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions. They are only used to facilitate and clarify the purpose of illustrating the embodiments of the present invention, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationship, or adjustments to the size should still fall within the scope of the technical content disclosed in the present invention, provided that they do not affect the effects and objectives that the present invention can produce.

[0047] It should be noted that, in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0048] Currently, train dispatchers cannot use train operation plans to remind trains that require wireless dispatch orders when passing through speed-limited sections in the near future; manual monitoring is required. Furthermore, according to relevant regulations, train dispatchers are required to record the sending and receiving of wireless dispatch orders for each train, but these records are currently all paper-based and lack electronic documentation. Therefore, train dispatchers cannot perform real-time inquiries, posing certain safety risks and potential hazards.

[0049] To address the aforementioned shortcomings, embodiments of the present invention provide a method for processing boarding prompts and confirmations for railway wireless dispatching commands, such as... Figure 1 As shown, it includes the following steps: receiving a speed limit wireless dispatch command; extracting key speed limit information from the command to determine the speed limit section; dynamically calculating all trains affected by the speed limit within the configured time frame that will pass through the speed limit section based on railway operation data; prompting the train dispatcher to send the speed limit wireless dispatch command to the affected trains that are about to pass through the speed limit section; when the dispatcher sends the command, monitoring whether a driver's receipt of the command is received, and / or determining whether the affected trains have passed through the speed limit section, to confirm the status of the command. The speed limit section is located within a section of track, on the main line within a station, on a siding within a station, or on a section of track crossing the main line within a station.

[0050] The railway operation data includes train operation plans, route sequences, static station data, station display information, dispatching orders, and train control speed limit operation events. Specifically, the train operation plan specifies the train's route, timetable, and stops. The route sequence refers to the path the train takes within a station or section. Based on the train operation plan and route sequence, train numbers that may pass through the speed-limited section within a certain period can be obtained in advance. This allows train dispatchers to be reminded in advance to issue speed limit wireless dispatching orders to trains that may pass through the speed-limited section, reducing the workload of train dispatchers.

[0051] Furthermore, since the dispatching commands include various commands for managing and controlling trains, such as train operation adjustment commands, construction dispatching commands, and temporary speed limit commands, receiving the speed limit wireless dispatching command specifically includes: receiving the dispatching command from the centralized dispatching system and checking the title and content of the dispatching command; if the title and / or content of the dispatching command contains the "speed limit" field, then the dispatching command is determined to be the speed limit wireless dispatching command. Through the above receiving and checking steps, the accurate identification of the speed limit wireless dispatching command is achieved, thereby ensuring the timely issuance of the speed limit wireless dispatching command.

[0052] Specifically, the determination of the onboard status of the speed limit wireless dispatch command is made by comparing the dispatch command number, speed limit section, and speed limit value in the speed limit wireless dispatch command sent by the train dispatcher and the driver's signed receipt of the speed limit wireless dispatch command. If the dispatch command number, speed limit section, and speed limit value are all the same, the onboard status of the speed limit wireless dispatch command is confirmed as "onboard"; otherwise, the onboard status of the speed limit wireless dispatch command is confirmed as "not onboard".

[0053] The step of determining whether the train affected by the speed restriction has passed through the speed-restricted section includes: calculating the train position of the train affected by the speed restriction using the station display information; determining whether the train has passed through the speed-restricted section based on the train position; if the train position is greater than the end kilometer marker of the speed-restricted section when the line kilometer marker is increasing in the train's direction of travel, or if the train position is less than the end kilometer marker of the speed-restricted section when the line kilometer marker is decreasing in the train's direction of travel, then it is determined that the train affected by the speed restriction has passed through the speed-restricted section, and the status of the speed-restricted radio dispatch command is confirmed as "passed through the speed-restricted section". Otherwise, the status of the speed-restricted radio dispatch command is confirmed as "not passed through the speed-restricted section". It should be noted that the "passed through the speed limit section" speed limit radio dispatch command boarding status and the "on board" speed limit radio dispatch command boarding status are parallel and can be superimposed. That is, when the speed limit radio dispatch command boarding status is "on board", if the train passes through the speed limit section, the speed limit radio dispatch command boarding status can be confirmed as "passed through the speed limit section".

[0054] Furthermore, when the signal to the speed-limited section is open, if the driver of the train about to pass through the speed-limited section and affected by the speed limit has not signed for the speed limit wireless dispatch order, that is, if the status of the speed limit wireless dispatch order on board is "not on board", the train dispatcher is prompted again to send the speed limit wireless dispatch order or to query and view the onboard record of the speed limit wireless dispatch order, so as to ensure that the speed limit wireless dispatch order is issued in a timely manner and to ensure the safety of train operation.

[0055] Optionally, the key speed limit information in the speed limit wireless dispatch command can be extracted using regular expressions; wherein, the key speed limit information includes station name, line name, direction of travel, speed limit start and end kilometer markers, and speed limit value. The speed limit section is determined based on the key speed limit information. For example, in one embodiment, the regular expression for the speed limit wireless dispatch command is as follows:

[0056] "Speed ​​limit (2,3)km / h at [$,$](\s*.*\s*)line(\s*\d{0,6}\s*)km(\s*\d{0,3}\s*)m to (\s*\d{0,6}\s*)km(\s*\d{0,3}\s*)m and (\s*.*\s*)line(\s*\d{0,6}\s*)km(\s*\d{0,3}\s*)m to (\s*\d{0,6}\s*)km(\s*\d{0,3}\s*)m";

[0057] The speed limit information can be extracted from the speed limit wireless dispatch command "Due to strong winds, the speed limit alarm is set at 300 km / h for your train between 889km109m and 905km704m on the downline between Fuyang West Line Station (excluding) and Yingshang North Station (including) and Fengtai South Station (excluding)".

[0058] Furthermore, the dynamic calculation of all trains affected by speed restrictions passing through the speed-restricted section within the configured time period based on railway operation data specifically includes:

[0059] Initial calculation: Based on the first train operation plan, the first route sequence, the first static station data, and the first station representation information, calculate the trains affected by the speed limit that will pass through the speed limit section within the configured time, forming a first group of train sequence; the train dispatcher can send the speed limit wireless dispatch command to the trains affected by the speed limit in the order of the trains affected by the speed limit in the first group of train sequence.

[0060] Update Calculation: Based on the updated second train operation plan, second route sequence, second station indication information, the dispatching command, and the train control speed limit operation event, add or remove trains affected by speed limits in the Nth train sequence to form the (N+1)th train sequence, where N≥1. Repeat the update calculation for trains affected by speed limits in the Nth train sequence until a cancellation command for the speed limit wireless dispatching command is received or the train control speed limit is cancelled.

[0061] This is because train operation plans are adjusted according to actual conditions, necessitating continuous periodic updates and calculations for all trains affected by speed restrictions that may pass through the speed-restricted section within the configured timeframe. This ensures the accuracy of the affected train numbers and reduces the workload of train dispatchers. Furthermore, once a train affected by a speed restriction passes through the speed-restricted section, it needs to be removed from the corresponding train sequence. In this embodiment, the updated second train operation plan, second route sequence, second station indication information, dispatching commands, and train control speed restriction operation events are periodically updated based on update information sent by the centralized dispatching system.

[0062] The configuration time is greater than or equal to the duration from the sending of the speed limit wireless dispatch command to its receipt, so as to provide reassembly time to ensure that the speed limit wireless dispatch command can be received by the train, and to reserve time for the train dispatcher to monitor the speed limit wireless dispatch command, so as to ensure that the speed limit wireless dispatch command is issued in a timely manner.

[0063] Furthermore, after the speed limit wireless dispatching command boarding prompt and confirmation ends, the relevant records of the speed limit wireless dispatching command boarding prompt and confirmation are saved so that the train dispatcher can query and view the speed limit wireless dispatching command boarding records at any time.

[0064] Based on the speed limit wireless dispatch command boarding prompt and confirmation processing method provided in the above embodiments, the present invention also provides a speed limit wireless dispatch command boarding prompt and confirmation processing device, such as... Figure 2 As shown, the device includes: a wireless dispatching auxiliary server module 200, which is communicatively connected to the dispatching centralized system 100. The wireless dispatching auxiliary server module 200 is used to receive speed limit wireless dispatching commands to determine speed limit sections and dynamically calculate all speed-limited trains passing through the speed limit section within a configured time based on railway operation data; and a wireless dispatching auxiliary terminal module 300, which is communicatively connected to the wireless dispatching auxiliary server module 200. The wireless dispatching auxiliary terminal module 300 is used to receive and display the key speed limit information of the speed limit wireless dispatching command, and prompt the train dispatcher to send the speed limit wireless dispatching command to the speed-limited trains that are about to pass through the speed limit section, and prompt the train dispatcher to set up monitoring for the speed limit wireless dispatching command to be sent on board. After the train dispatcher sends the speed limit wireless dispatching command, the wireless dispatching auxiliary server module 200 confirms the status of the speed limit wireless dispatching command by checking whether a driver's receipt of the speed limit wireless dispatching command has been received and / or determining whether the speed-limited trains have passed through the speed limit section.

[0065] This embodiment automatically extracts key speed limit information from the speed limit wireless dispatch command through the wireless dispatch auxiliary server module 200. It can dynamically monitor and calculate the train numbers requiring a speed limit wireless dispatch command based on the speed limit section in the command and railway operation data (such as train operation plans and station display information). Simultaneously, the wireless dispatch auxiliary terminal module 300 can dynamically update, display, and store the issuance and receipt status of the speed limit wireless dispatch command, prompting the train dispatcher to issue wireless dispatch commands to trains about to pass through the speed limit section. Furthermore, this device can be upgraded and expanded within existing centralized dispatch systems, adapting to the requirements of train dispatchers and having wide applicability. Moreover, this device maximizes the utilization of existing centralized dispatch system's hardware, software, and network transmission channels, significantly reducing costs.

[0066] Among them, such as Figure 3 As shown, the wireless dispatching auxiliary server module 200 includes: a first communication processing unit 201, which is communicatively connected to the dispatching centralized system 100, which is communicatively connected to the train 400; the first communication processing unit 201 is used to receive railway operation data sent by the dispatching centralized system 100 and obtain train-related information from the dispatching centralized system 100; the railway operation data includes train operation plans, route sequences, static station data, station indication information, dispatching commands, and train control speed limit operation events; and a dispatching command processing unit 202, which communicates with the first communication processing unit 201. The system includes a communication connection for receiving the dispatch command, determining whether the dispatch command is the speed-limited wireless dispatch command, and calculating all speed-limited affected vehicles passing through the speed-limited section within the configured time; a monitoring processing unit 203, which is communicatively connected to the first communication processing unit 201, for monitoring whether a driver's receipt of the speed-limited wireless dispatch command is received, and / or determining whether the speed-limited affected vehicles have passed through the speed-limited section; and a display status processing unit 204, which is communicatively connected to both the first communication processing unit 201 and the monitoring processing unit 203, for displaying the vehicle status of the speed-limited wireless dispatch command.

[0067] Furthermore, such as Figure 3 As shown, the wireless dispatch auxiliary server module 200 also includes a first configuration processing unit 205. The first configuration processing unit 205 is used to configure the static station data within the jurisdiction of the dispatch centralized system 100, providing a data basis for subsequent determination of the speed limit wireless dispatch status. The static station data includes line name, line kilometer marker system, line kilometer marker range, station equipment and connection relationship.

[0068] Among them, such as Figure 4 As shown, the wireless dispatching auxiliary terminal module 300 includes: a second communication processing unit 301, which is communicatively connected to the first communication processing unit 201, for receiving the speed limit wireless dispatching command, the train numbers affected by the speed limit, and the boarding status of the speed limit wireless dispatching command; and a display operation processing unit 302, which is communicatively connected to the second communication processing unit 301, for displaying the speed limit wireless dispatching command, the train numbers affected by the speed limit, and the boarding status of the speed limit wireless dispatching command. Further, the wireless dispatching auxiliary terminal module 300 also includes a second configuration processing unit 303, which is communicatively connected to both the second communication processing unit 301 and the display operation processing unit 302, for loading the configuration files of the second communication processing unit 301 and the display operation processing unit 302 to realize their communication and display operation functions.

[0069] To improve the efficiency of vehicle prompting and confirmation for the speed limit wireless dispatch command, multiple threads are set between the monitoring processing unit 203, the display status processing unit 204, and the display operation processing unit 302 to support simultaneous vehicle prompting and confirmation for multiple speed limit wireless dispatch commands.

[0070] In summary, the railway wireless dispatching command boarding prompt and confirmation processing method and device provided by the present invention upgrades the issuance and receipt of speed limit wireless dispatching commands from a "human-to-human control" mode to a "human-machine control" mode, which can effectively improve the timeliness, reliability and security of sending and receiving speed limit wireless dispatching commands; at the same time, it significantly reduces the workload of train dispatchers in sending and confirming the receipt of wireless dispatching commands and improves the work efficiency of train dispatchers.

[0071] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
