Description

Technical Field

[0001] The present invention relates to the field of railway transportation technology, and in particular to a method and system for disabling traffic dispatching services in a high-speed railway skylight based on CTC. Background Art

[0002] The high-speed rail train dispatching (abbreviated as train dispatching) position is a key link in coordinating and commanding the lines, trains and other transportation resources within the section under its jurisdiction and completing the transportation production plan. Its business is characterized by high real-time, high security and high complexity. The high-speed rail train dispatching business is implemented under the coordination mechanism of the dispatching centralized system (CTC) and the dispatcher, including adjusting the train operation plan of the current train, monitoring the train operation status, mastering the status of key transportation production systems, editing and issuing dispatching orders, guiding station operation operations, coordinating and resolving conflicts in multi-station operations, and handling transportation emergencies.

[0003] The railway skylight is a time and space window for various railway professional types to complete equipment inspections, troubleshooting, upgrades and renovations. Within the skylight, some traffic dispatching services are suspended according to operational needs to provide a safe environment for operations and maximize the normal operation of traffic dispatching services outside the scope of suspension required for skylight operations.

[0004] The normal execution of traffic dispatching services is achieved through the accurate transmission of various directional information, including stage plans, reporting points, dispatching orders, blocking, switch single operations and alarms. This information is generated, transmitted and executed in the CTC system. At present, the measures for disabling traffic dispatching services include manually executing the deactivation dispatching order or shutting down the corresponding CTC subsystem, but neither can meet the needs of safe and accurate deactivation of traffic dispatching services. Specifically: 1. According to the skylight operation range, manually avoid the traffic dispatching business that needs to be disabled, that is, the dispatcher stops using the corresponding CTC function according to the disabled range. Specifically: the method of manually stopping the use of the corresponding CTC function is to confirm and register the disabled range of the traffic dispatching business attached to the operation dispatching order by two people at the dispatching post, and then take avoidance measures to ensure that the traffic dispatching business within the disabled range is not executed.

[0005] The above methods have the following defects: (1) the deactivation of services is completely manually performed by the dispatcher, which lacks "technical defense" support and is prone to dispatch safety accidents caused by misoperation; (2) during the window period, the dispatcher is still responsible for the dispatch command of the non-deactivation range. The information of the deactivated and non-deactivated parts needs to be manually distinguished by the dispatcher and the disposal method needs to be determined, which reduces the dispatcher's work efficiency.

[0006] 2. Shut down the corresponding subsystem of CTC, and use the missing functions of CTC system to cover the deactivation scope required for skylight operation. Specifically: the way to shut down the corresponding subsystem of CTC is to shut down one or several of the subsystems such as CTC communication front-end server, application server, dispatching terminal, station autonomous machine, station server, vehicle terminal, busy board terminal, etc. according to the operation requirements, and use the missing functions of CTC system to deactivate the traffic dispatching business within the deactivation scope required for skylight operation, so as to avoid the traffic dispatching business from encroaching on skylight operation.

[0007] The defects of the above method are: (1) The scope of business functions carried by the subsystem does not strictly correspond to the scope of suspension required for skylight operation. Generally, the strategy of shutting down the CTC function must cover the required suspension scope, resulting in unnecessary suspension and expanding the scope of the skylight; (2) The CTC system has many external interfaces, and external systems mostly rely on CTC for clock timing, master-slave system arbitration and execution status verification. The shutdown of the CTC subsystem causes the timing, arbitration and status recording functions to be shut down, which in turn affects the status of the external system. When the skylight point ends, the external system needs to be restarted to restore to normal status, which increases the risk of abnormal status transmission between systems and leads to an expansion of the suspension scope.

[0008] Apart from the above manual solutions, existing automated solutions are mainly used for the optimization of railway skylights or the control of operations during railway skylights, but none of them can achieve the precise deactivation of train dispatching services. For example, the Chinese invention patent application with publication number CN119250394A, "A railway skylight optimization method, device, equipment and readable storage medium", and the Chinese invention patent application with publication number CN110194199A, "A control system for railway skylight operations based on satellite positioning".

[0009] In view of this, the present invention is proposed. Summary of the invention

[0010] The purpose of the present invention is to provide a method and system for disabling traffic dispatching services during a high-speed railway skylight based on CTC, which can effectively improve the accuracy of disabling traffic dispatching services during the skylight period and eliminate safety hazards caused by human misoperation.

[0011] The objective of the present invention is achieved through the following technical solutions: A CTC-based high-speed railway skylight traffic dispatching service deactivation system, comprising: a CTC information control subsystem arranged in a CTC system, through which a traffic dispatching service deactivation strategy under the high-speed railway skylight is set, and corresponding information is deactivated; wherein the CTC system is a centralized dispatching system; The CTC information control subsystem includes: an information control center module and an information control station module; the information control center module is connected to the application server in the CTC system, and the information control station module is connected to the station extension in the CTC system; the information control center module is responsible for setting the CTC's high-speed railway traffic dispatching business deactivation strategy under the skylight, and deactivating the information sent by the application server in combination with the traffic dispatching business deactivation strategy, and sending the traffic dispatching business deactivation strategy to the information control station module; the information control station module deactivates the information sent by the station extension in combination with the received traffic dispatching business deactivation strategy.

[0012] A method for disabling traffic dispatching services within a high-speed railway skylight based on CTC, the method is implemented based on the aforementioned system, the method comprising: setting a traffic dispatching service disabling strategy under the high-speed railway skylight through a CTC information management and control subsystem provided in the CTC system, and disabling corresponding information; wherein the CTC system is a centralized dispatching system.

[0013] It can be seen from the technical solution provided by the above-mentioned present invention that a two-level structure subsystem for information control and management deployed on the CTC application server and the station extension is designed. The two-level structures cooperate with each other and jointly support the information control function, and through information control measures, the train dispatching business function can be accurately disabled, eliminating the safety hazards caused by human misoperation.

[0020] Embodiment 1 The embodiment of the present invention provides a high-speed railway skylight traffic adjustment service deactivation system based on CTC, such as Figure 1 As shown, it mainly includes: a CTC information control subsystem arranged in the CTC system, through which a traffic dispatching business deactivation strategy under the high-speed railway skylight is set, and corresponding information is deactivated. Figure 1 The communication server, train terminal, traffic control console, and various interfaces shown are all existing parts of the CTC system and will not be described in detail in the present invention.

[0021] The CTC information control subsystem includes: an information control center module and an information control station module; the information control center module is connected to the application server in the CTC system, and the information control station module is connected to the station extension in the CTC system; the information control center module is responsible for setting the CTC's high-speed railway traffic dispatching business deactivation strategy under the skylight, and deactivating the information sent by the application server in combination with the traffic dispatching business deactivation strategy, and sending the traffic dispatching business deactivation strategy to the information control station module; the information control station module deactivates the information sent by the station extension in combination with the received traffic dispatching business deactivation strategy.

[0022] Preferably, the information control center module is connected to the application server in the CTC system as an information flow branch node; the application server is synchronously modified to have the ability to access the information control center module, and the channel interface to the information control center module is shielded during non-window periods, and the corresponding channel interface is enabled during window periods; the information control station module is connected to the station extension in the CTC system, and the station extension shields the channel interface to the information control station module during non-window periods, and the corresponding channel interface is enabled during window periods.

[0023] Preferably, the information control center module is configured with a human-computer interaction interface, and the deactivation strategy of the line dispatching business is set in a human-computer interaction manner; the human-computer interaction interface is provided with a skylight start time setting area, a deactivation function list, a deactivation range list and a deactivation time setting area; wherein, the skylight start time setting area is used to set the time when the skylight starts; the deactivation function list is used to select the deactivation function; the deactivation range list is used to select the deactivation range; the deactivation time is used to set the start and end time of the deactivation; the line dispatching business deactivation strategy is formed in combination with the skylight start time, deactivation function, deactivation range and deactivation time.

[0026] Those skilled in the art can understand that the reporting center information refers to the information uploaded by the station to the application server. The center here mainly refers to the CTC central subsystem, including application servers, communication servers, dispatching desks and other central equipment.

[0027] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the system provided by the embodiment of the present invention is described in detail with reference to a specific embodiment below.

[0028] The present invention designs a system based on the CTC system to realize accurate deactivation of the train dispatching service function through information control measures, which mainly includes three parts: 1. System structure design, combining with the CTC system architecture, designing a two-level structural subsystem of information control deployed in the CTC application server and the station extension, the two-level structure cooperates with each other and jointly supports the information control function; 2. Information control scheme, facing the demand for deactivation of train dispatching service during the skylight period, designing the CTC information control subsystem, truncating the corresponding information, reducing the target range or disabling the function; 3. Communication protocol design, expanding the CTC internal communication protocol, realizing the target address modification and function disabling processing of the controlled information. The following is a detailed introduction to each part.

[0029] 1. System structure design.

[0030] (1) Analysis of CTC system structure and information flow.

[0031] Application servers and station extensions are key nodes for information processing of train dispatching services in the CTC system. Application servers centrally process interactive information between dispatching desks, between dispatching desks and stations, and between CTC and external systems of the center. Interactive information between dispatching desks includes dispatching orders between stations, neighboring station plans, confirmation receipts between stations, etc.; interactive information between dispatching desks and stations includes plan distribution, dispatching order issuance, station reporting, route arrangement, real-time display, etc.; interactive information between CTC and external systems of the center includes interactive information between CTC and temporary speed limit servers (TSRS), radio block centers (RBC), and transportation dispatch management systems (TDMS). Station extensions centrally process information interaction between modules of the station, between stations, and between stations and dispatching centers. Inter-module information includes interactive information between vehicle terminals, autonomous machines, and station interface modules; inter-station information includes advance notices, advance notice confirmations (approval, rejection), joint indication information, section change information, etc.; interactive information between stations and dispatching centers is the same as that of application servers.

[0032] The application server and station extension process information in the following ways: forwarding, broadcasting, regeneration and splicing. Forwarding refers to sending information in a directional manner according to the target address contained in the information to ensure the correct flow of information. Broadcasting refers to broadcasting to all relevant subsystems according to fixed rules according to the type of information to achieve coordination and consistency of the receiving information subsystems. Regeneration refers to determining the new target address of the information based on the real-time status needs, regenerating one or more copies of the information and sending them to the new target address without changing the original information flow. The difference between broadcasting and regeneration is that broadcasting is sent according to fixed rules and does not receive receipt information, while regeneration determines the sending range, sends in a directional manner and waits for receipts according to the real-time status needs. Splicing refers to the integration of information from two or more sources, which is the splicing of combined information, such as the splicing of train operation plans for stations managed by multiple dispatching desks, and the splicing of cross-station train number tracking information.

[0033] (2) Two-level structure of information control subsystem.

[0034] In the embodiment of the present invention, an information control subsystem is designed based on the CTC system, including an information control center module and an information control station module, which are respectively connected to the application server and the station extension. The structure is as follows: Figure 1 shown.

[0035] The information control center module does not serially access the existing information channel of CTC, but is only connected to the application server as an information flow branch node, with two-way communication capabilities. The application server is modified synchronously to have the ability to access the information control center module. The channel interface to the information control center module is shielded during non-window periods, and the interface is enabled during window periods. During the implementation process, an independent server device can be set up for the information control center module, or the information control center module can be run on the application server device. Due to the limited space of station equipment and weak scalability, the station module is deployed in the integrated processing machine, sharing hardware resources with the station extension and autonomous machine. The station extension adds an interface to the information control station module, and the interface activation and shutdown strategy is the same as the application server. An information flow branch node means that the device is not on the necessary path of CTC information, that is, CTC information can be accurately delivered without passing through the device and does not reduce the completeness of the overall business.

[0036] Since the CTC central switchboard system is rich in resources and the relevant measures for disabling the train dispatching business are mainly mastered and executed by the dispatcher, the information control center module has a clear, intuitive and friendly human-computer interaction interface, and accurate and diverse deactivation strategy control functions. It is the main control unit in the two-level structure of the information control subsystem. The information control station module is scattered in multiple stations. In order to reduce the difficulty and cost of system deployment, its function is set as a passive execution unit, and it is only responsible for the information control business of the station.

[0037] (3) Human-computer interaction interface and deactivation strategy setting method.

[0038] In order to enable dispatchers to efficiently and accurately enter the scope of deactivation of line dispatching services, the present invention designs a relatively concise and friendly human-computer interaction interface. Specifically, by configuring the human-computer interaction interface of the information control center module and adopting a human-computer interaction method, the deactivation strategy of the line dispatching services can be intuitively set.

[0039] In an embodiment of the present invention, a skylight start time setting area, a disabled function list, a disabled range list and a disabled time setting area are provided in the human-computer interaction interface; wherein, the skylight start time setting area is used to set the time when the skylight is started; the disabled function list is used to select disabled functions, including speed limit, dispatch order, indication, reporting point, notice, control mode conversion, etc.; the disabled range list is used to select the disabled range, and is combined with the disabled function list to clarify the specific disabled range of the current disabled function; the disabled time is used to set the start and end time of the disabled, and the start and end minutes need to be set on the ruler, with the start minutes after the skylight start time as the disabled start time, and the end minutes after the skylight start time as the disabled end time; the skylight start time, disabled function, disabled range and disabled time are combined to form a traffic dispatching service disabled strategy.

[0040] like Figure 2As shown in the figure, a schematic diagram of the human-computer interaction interface is shown. Figure 2 In the human-computer interaction interface shown, after setting the sunroof start time, deactivation function, deactivation range and deactivation time, click the Apply button to form a deactivation strategy.

[0041] In addition, the human-computer interaction interface also has a deactivation policy list area, which can display the set deactivation policy. The deactivation policy includes deactivation function, deactivation scope and deactivation time, etc. The deactivation policy list area displays the set deactivation policy and the current effective status. Select the policy entry in the deactivation policy list area and click the delete button to forcibly delete the deactivation policy, and the corresponding deactivated service in the effective state will be immediately un-deactivated.

[0042] Furthermore, the human-computer interaction interface is also provided with an editable template group for storing commonly used deactivation combination strategies. For example, template group 1 corresponds to the deactivation combination strategy storage of the information control center module, and template group 2 corresponds to the deactivation combination strategy storage of the information control station module. Click the template edit button to enter the deactivation combination strategy storage setting mode. The deactivation combination strategy refers to a deactivation combination formed by two or more deactivation strategies in the deactivation function list area, which is selected for use when the sunroof function is subsequently deactivated.

[0043] 2. Information management and control plan.

[0044] (1) Information deactivation processing method.

[0045] According to the four ways that application servers and station extensions process information, namely forwarding, broadcasting, regeneration and splicing, a customized information deactivation method is designed.

[0046] There is a fixed target address in the forwarding and splicing packets, and the information source waits for the target subsystem to receive the receipt after sending such information. In order to ensure the process integrity of such information, it is invalidated. The invalidation processing method is to modify the function code field to an invalid value according to the line dispatch service deactivation policy, without changing its information transmission path and type.

[0047] Broadcast information sources do not need to receive receipts from the target subsystem, and broadcast information occupies more channel resources. Therefore, according to the line modulation service deactivation policy, the deactivation method for this type of information is to truncate it and stop subsequent transmission.

[0048] Regeneration information involves multiple target addresses after regeneration. According to the deactivation policy of the line dispatching service (specifically the deactivation scope), the deactivated subsystem ID (identification) in the target field is deleted, that is, the sending scope of the information is narrowed according to the deactivation scope. The subsystem ID is a unique identification code within the CTC system, which is identified by a decimal 4-digit number.

[0049] (2) Information control methods within high-speed railway skylights.

[0050] During the non-window period, the two-level structure system modules of the information control subsystem are in a silent state. Their own status does not affect the CTC system business, and does not reduce the CTC security level and system availability. During the window period, the information control center module is connected in series to the CTC information path. During this period, the application server forwards, broadcasts, regenerates, and splices the received information according to the non-window period rules, and transmits it to the information control center module; the information control center module deactivates the information and sends it out according to the target address, except for the truncated broadcast information.

[0051] like Figure 3 As shown in the figure, a schematic diagram of information flow and control in the skylight of a high-speed railway is shown. The information input to the server includes: information sent from the dispatching desk, adjacent dispatching desks, external interfaces, etc., which is called central source information. In order to maintain the business integrity and log record integrity of the application server itself, the information control center module is connected in series to the output end of the application server. All information from the center source is directly input into the application server according to the information transmission mode during the non-skylight period. The application server forwards, broadcasts, regenerates, and splices according to the rules during the non-skylight period, and then enters the information control center module for deactivation information processing. After the deactivation processing by the information control center module, except for the truncated broadcast information, it is sent to the application server by the information control center module (that is, only the forwarding, splicing and regeneration information after deactivation processing is sent at this time), and the application server sends it to other subsystems or stations of the center according to the target address.

[0052] According to the information destination, the information from the center includes three categories: station information, inter-station information, and information reported to the center. Based on the objective situation of limited computing resources of the station subsystem, the large number of stations, and the wide area network bandwidth resources, a station information management and control method based on the principles of saving computing and network resources and decentralized processing is designed, as follows: All information within the station is sent by the extension to the information control station module, and then sent to other subsystems within the station after being deactivated, so as to avoid the invalid occupation of resources of the subsystems within the station by broadcast information; information from other subsystems within the station to the station extension is transmitted in the original way.

[0053] All the information reported to the center is sent by the extension to the information control station module, and reported to the center after being deactivated, so as to avoid the deactivated broadcast information occupying the wide area network channel bandwidth. At the same time, the goal of decentralized processing of station information is achieved, avoiding the risk of resource squeeze caused by the centralized processing of a large amount of station deactivation information by the central module.

[0054] Information transmitted between stations is grouped into forwarding, splicing, broadcasting, and regeneration categories. The control measure for forwarding and splicing information is invalidation. In order not to expand the scope of invalidation, the inter-station extension directly transmits it according to the original information path, and the station extension of the information receiving station sends it to the corresponding information control station module for invalidation. The control measures for broadcast and regeneration information are truncation and reduction of the target range, respectively. The station extension of the information sending station sends it to the corresponding information control station module for invalidation, which can reduce the occupation of inter-station wide area network channel resources.

[0055] In the embodiment of the present invention, under the high-speed railway skylight, the information control center module mainly performs deactivation processing on various types of information sent by the application server (center-sourced information), among which the broadcast information is truncated, and the other three types of information are sent out through the application server after corresponding deactivation processing; the information control station module mainly performs deactivation processing on the information sent by the station extension (station source). During this process, the station extension will receive some information that has been deactivated by the information control center module, and this information does not need to be deactivated again.

[0056] 3. Communication protocol design.

[0057] In the embodiment of the present invention, the content of the information packet is modified for the information after the deactivation process, and the communication protocol is expanded. Specifically, for the invalidation process of forwarding and splicing type information, and the target range reduction process for regeneration type information, the information packet content needs to be modified, and the communication protocol is expanded and modified. As shown in Table 1, the expanded communication protocol not only includes the existing communication protocol field, but also adds two fields of validity and information processing type. Among them, the validity field is used to indicate whether the information after the deactivation process is processed according to normal business logic or only as heartbeat information. For example, when the value of the validity field is 1, the information receiving subsystem (a general term for a series of subsystems that receive the information) processes the information according to normal logic; when the value of the validity field is 2, the information receiving subsystem only uses it as heartbeat information and does not process business data; the information processing type includes forwarding, broadcasting, regeneration and splicing. After the application server processes the information according to fixed rules, it fills in the field information to support the CTC information control subsystem to perform information truncation, target range reduction or function invalidation processing in the manner described above.

[0058] Table 1: Expanded communication protocol

[0059] The above-mentioned scheme provided by the embodiment of the present invention is aimed at the demand for refined suspension of train dispatching services during the window period, and designs an information control subsystem based on CTC information control, which includes two-level modules, among which the information control center module has the information suspension policy management function, and the two-level modules cooperate with each other to realize the refined service suspension function. In addition, it also combines the information processing methods of application servers and station extensions, namely forwarding, broadcasting, regeneration and splicing, and designs targeted information suspension control measures to minimize the occupation of channels and computing resources by information control, disperse the station control pressure, and improve the feasibility of the information control subsystem and control business deployment.

[0060] Technical personnel in the relevant field can clearly understand that for the convenience and simplicity of description, only the division of the above-mentioned functional modules is used as an example. In actual applications, the above-mentioned functions can be assigned to different functional modules as needed, that is, the internal structure of the system can be divided into different functional modules to complete all or part of the functions described above.
