Description

Technical Field

[0001] The present invention relates to the technical field of railway transportation, and particularly to a method and system for deactivating the operation control business during the skylight period of high-speed railways based on CTC. Background Art

[0002] The high-speed rail operation control (referred to as operation control for short) position is a key link for overall planning and commanding transportation resources such as lines and trains within the jurisdiction section, and for completing the transportation production plan. Its business features high real-time, high safety, and high complexity. The high-speed rail operation control business is realized under the collaborative mechanism of the Centralized Traffic Control (CTC) system and the dispatcher, including adjusting the train operation plan of the current shift, monitoring the train operation status, mastering the status of key transportation production systems, editing and issuing dispatching orders, guiding the station operation, coordinating and resolving multi-station operation conflicts, and handling transportation emergencies, etc.

[0003] The railway skylight is the time and space window for various railway professional types of work to complete equipment inspection, fault troubleshooting, upgrading and transformation, etc. Within the skylight range, some operation control businesses are deactivated according to the operation requirements to provide a safe environment for the operation, and the operation control business outside the deactivation range required for the skylight operation is maximally maintained to operate normally.

[0004] The normal execution of the operation control business is achieved through the accurate transmission of various directed information, including stage plans, train arrival reports, dispatching orders, block systems, single-point switch operations, and alarms, etc. These information are generated, transmitted, and executed within the CTC system. At present, the measures for deactivating the operation control business include two methods: manually executing the deactivation dispatching order or closing the corresponding CTC subsystem, but neither can meet the requirements of safe and accurate deactivation of the operation control business. Specifically:

[0005] 1. According to the skylight operation range, manually avoid the operation control business to be deactivated, that is, the dispatcher stops using the corresponding CTC functions according to the deactivation range. Specifically: the method of manually stopping using the corresponding CTC functions is to confirm and register by two persons in the dispatching position according to the operation control business deactivation range attached to the operation dispatching order, and then take artificial avoidance measures to ensure that the operation control business within the deactivation range is not executed.

[0006] The defects of the above method are as follows: (1) Completely manually executed by the dispatcher for business deactivation, lacking "technical prevention" support, it is easy to cause dispatching safety accidents due to misoperations; (2) During the skylight period, the dispatcher still shoulders the responsibility of operation control command for the non-deactivated range, and the information of the deactivated part and the non-deactivated part needs to be manually distinguished and judged by the dispatcher for handling methods, reducing the operation efficiency of the dispatcher.

[0007] 2. Shut down the corresponding CTC subsystem and utilize the lack of CTC system functions to cover the deactivation scope required for skylight operations. Specifically: The way to shut down the corresponding CTC subsystem is to shut down one or several of the subsystems such as the CTC communication front-end server, application server, dispatching console terminal, station self-discipline machine, station server, train operation terminal, and occupation board terminal according to the operation requirements. Utilize the lack of CTC system functions to deactivate the line dispatching services within the deactivation scope required for skylight operations, and avoid the encroachment of line dispatching services on skylight operations.

[0008] The deficiencies of the above methods are as follows: (1) The service function scope borne by the subsystem does not strictly correspond to the deactivation scope required for skylight operations. Generally, the strategy of shutting down the functions of CTC must cover the required deactivation scope, resulting in unnecessary deactivation and expanding the skylight impact scope; (2) There are many external interfaces in the CTC system, and many external systems rely on CTC for clock timing, master-slave system arbitration, and execution status verification. The shutdown of the CTC subsystem leads to the shutdown of timing, arbitration, and status recording functions, thereby affecting the status of external systems. When the skylight period ends, the external systems need to be restarted to return to the normal state, increasing the risk of propagation between systems in the abnormal state, and further leading to the expansion of the deactivation scope.

[0009] Except for the above manual solutions, the existing automated solutions are mainly used for the optimization of railway skylights or the operation control during railway skylights, but none of them can achieve the precise deactivation of line dispatching services. For example, the Chinese invention patent application "A Method, Device, Equipment, and Readable Storage Medium for Optimizing Railway Skylight Solutions" with the publication number CN119250394A, and the Chinese invention patent application "A Control System for Railway Skylight Operations Based on Satellite Positioning" with the publication number CN110194199A.

[0010] In view of this, the present invention is specifically proposed. Summary of the Invention

[0026] Embodiment 1

[0027] The embodiment of the present invention provides a system for suspending the operation of the train operation dispatching service during the high-speed railway skylight period based on CTC, as Figure 1 shown, which mainly includes: a CTC information control and management subsystem provided in the CTC system, setting a strategy for suspending the operation of the train operation dispatching service during the high-speed railway skylight period through the CTC information control and management subsystem, and performing suspension processing on the corresponding information. Figure 1 The communication server, the station operation terminal, the train operation dispatching console, and various interfaces shown belong to the existing parts in the CTC system, and the present invention will not elaborate on them.

[0028] 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 sub - machine in the CTC system; the information control center module is responsible for setting the line - dispatching service deactivation strategy under the high - speed railway skylight in CTC, and deactivating the information sent by the application server in combination with the line - dispatching service deactivation strategy, and sending the line - dispatching service deactivation strategy to the information control station module; the information control station module deactivates the information sent by the station sub - machine in combination with the received line - dispatching service deactivation strategy.

[0029] 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 blocked during non - skylight periods and enabled during skylight periods; the information control station module is connected to the station sub - machine in the CTC system, and the channel interface of the station sub - machine to the information control station module is blocked during non - skylight periods and enabled during skylight periods.

[0030] Preferably, the information control center module is configured with a man - machine interaction interface, and the line - dispatching service deactivation strategy is set in a man - machine interaction manner; the man - machine 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; among them, the skylight start - time setting area is used to set the moment 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 times of deactivation; the line - dispatching service deactivation strategy is formed by combining the skylight start - time, deactivation function, deactivation range, and deactivation time.

[0031] Preferably, the deactivation processing of information includes: for forwarding and splicing information, invalidation processing is performed in combination with the line - dispatching service deactivation strategy; for broadcast information, truncation processing is performed in combination with the line - dispatching service deactivation strategy; for regeneration information, the processing of narrowing the target range is performed in combination with the line - dispatching service deactivation strategy.

[0033] The station sub - machine is divided into in - station information, inter - station information, and information reported to the center according to the destination of the information, and the information control station module performs the following processing in combination with the received line - dispatching service deactivation strategy:

[0034] For in-station information, it is all sent from the station extension to the information control station module. The information control station module performs deactivation processing in combination with the train operation dispatcher business deactivation strategy and then sends it to other in-station subsystems.

[0035] For information reported to the center, it is all sent from the station extension to the information control station module. After the information control station module performs deactivation processing in combination with the train operation dispatcher business deactivation strategy, it is reported to the center.

[0036] For inter-station information, the station extension groups it according to forwarding and splicing types, as well as broadcasting and regeneration types. After the forwarding and splicing type information is grouped into one group, it is directly transmitted to the station extension of the information receiving station 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 processing. After the broadcasting and regeneration type information is grouped into one group, the station extension of the information sending station sends it to the corresponding information control station module for invalidation processing.

[0037] Those skilled in the art can understand that the information reported to the center refers to the information uploaded by the station to the application server. Here, the center mainly refers to the CTC central subsystem, including central devices such as the application server, communication server, and dispatching console.

[0038] In order to more clearly show the technical solution provided by the present invention and the technical effects produced, the following uses specific embodiments to describe in detail the system provided by the embodiments of the present invention.

[0039] Based on the CTC system, the present invention designs a system for accurately deactivating the train operation dispatcher business function through information control measures, which mainly includes three parts: 1. System structure design: Combining the CTC architecture, design an information control two-level structure subsystem deployed on 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 plan: Facing the train operation dispatcher business deactivation requirements during the skylight period, design a CTC information control subsystem to truncate, narrow the target range, or invalidate the corresponding information; 3. Communication protocol design: Extend the CTC internal communication protocol to implement the modification of the target address and the invalidation of the function of the controlled information. The following makes a detailed introduction to each part.

[0040] 1. System structure design.

[0041] (1) Analysis of the CTC system structure and information flow direction.

[0042] The application server and the station sub - machine are key nodes for processing train operation dispatching business information in the CTC system. The application server centrally processes the interaction information between dispatching consoles, between the dispatching console and the station, and between CTC and external systems of the center. The interaction information between dispatching consoles includes inter - console train operation orders, adjacent console plans, inter - console confirmation receipts, etc.; the interaction information between the dispatching console and the station includes plan distribution, train operation order issuance, station reporting of train arrival / departure times, route setting, real - time indication, etc.; the interaction information between CTC and external systems of the center includes the interaction information between CTC and systems such as the Temporary Speed Restriction Server (TSRS), the Radio Block Center (RBC), and the Transport Dispatching Management System (TDMS). The station sub - machine centrally processes the information interaction between each module of the station, between stations, and between the station and the dispatching center. The information between modules includes the interaction information between the train operation terminal, the self - discipline machine, and the station interface module; the information between stations includes advance notice, advance notice confirmation (agreement, rejection), junction indication information, section direction change, etc.; the interaction information between the station and the dispatching center is the same as that of the application server.

[0043] The processing methods of information by the application server and the station sub - machine include forwarding, broadcasting, regeneration, and splicing. Forwarding means sending information in a targeted manner according to the destination address contained in the information to ensure the correct flow direction of the information. Broadcasting means broadcasting to all relevant subsystems according to the information type and fixed rules to achieve the coordination of the receiving information subsystems. Regeneration means determining new information destination addresses based on real - time status requirements, and on the basis of not changing the original information flow direction, regenerating one or more copies of the information and sending it to the new destination addresses in a targeted manner. 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 according to real - time status requirements, sends it in a targeted manner and waits for the receipt. Splicing means integrating information from two or more sources, which is the splicing of junction information. For example, the splicing of train operation plans of stations jointly managed by multiple dispatching consoles, and the splicing of cross - station train number tracking information.

[0044] (2)Two - level structure of the information control and management subsystem.

[0045] In the embodiment of the present invention, an information control and management subsystem is designed based on the CTC system, which includes an information control and management center module and an information control and management station module, and is respectively connected to the application server and the station sub - machine. The structure is as Figure 1 shown.

[0046] The information control center module is not serially connected to the existing CTC information path. It is only connected to the application server as an information flow branch node and has two-way communication capabilities. The application server is synchronously modified to be capable of accessing the information control center module. During non-skylight periods, the channel interface to the information control center module is blocked, and this interface is enabled during skylight periods. During implementation, 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 limited space and weak expandability of station equipment, the station module is deployed in the integrated processor and shares hardware resources with the station sub-machine and the self-discipline machine. The station sub-machine newly adds an interface to the information control station module, and the interface enabling and disabling policies are the same as those of 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 this device and the integrity of the overall business is not reduced.

[0047] Since the CTC central mainframe system has rich resources and the relevant measures for suspending train operation dispatching services are mainly controlled and executed by dispatchers, the information control center module has a clear, intuitive, and friendly human-machine interface and accurate and diverse suspension strategy control functions, and is the main control unit in the two-level structure of the information control subsystem. The information control station modules are scattered and run in multiple stations. To reduce the system deployment difficulty and cost, their functions are set as passive execution units and are only responsible for information control services at stations.

[0048] (3) Human-machine interface and suspension strategy setting method.

[0049] In order to enable dispatchers to efficiently and accurately enter the scope of suspended train operation dispatching services, the present invention designs a relatively concise and friendly human-machine interface. Specifically, by configuring the human-machine interface of the information control center module and adopting a human-machine interaction method, the suspension strategy of train operation dispatching services is intuitively set.

[0050] In the embodiment of the present invention, the human-machine interface is provided with a skylight start time setting area, a suspension function list, a suspension scope list, and a suspension time setting area; among them, the skylight start time setting area is used to set the moment when the skylight starts; the suspension function list is used to select suspension functions, including speed limit, train order, indication, train reporting, pre-warning, control mode conversion, etc.; the suspension scope list is used to select the suspension scope, and in combination with the suspension function list, it clarifies the specific suspension scope of the current suspension function; the suspension time is used to set the start and end times of suspension, and the start and end minutes need to be set on the scale. The start minute after the skylight start time is used as the suspension start time, and the end minute after the skylight start time is used as the suspension end time; combining the skylight start time, suspension function, suspension scope, and suspension time forms the suspension strategy of train operation dispatching services.

[0051] Such as Figure 2As shown, a schematic diagram of the human-machine interaction interface is presented. In Figure 2 In the human-machine interaction interface shown, after setting the skylight start time, deactivation function, deactivation range, and deactivation time, click the Apply button to form a deactivation policy.

[0052] In addition, a deactivation policy list area is provided in the human-machine interaction interface, which can display the set deactivation policies. The deactivation policies include deactivation functions, deactivation ranges, deactivation times, etc. The set deactivation policies and their current effective status are displayed in the deactivation policy list area. Select a 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 deactivated.

[0053] Furthermore, an editable template group is provided in the human-machine interaction interface for storing common deactivation combination policies. For example, Template Group 1 corresponds to the storage of deactivation combination policies for the information control center module, and Template Group 2 corresponds to the storage of deactivation combination policies for the information control station module. Click the Template Edit button to enter the deactivation combination policy storage setting mode. The deactivation combination policy refers to the formation of a deactivation combination of two or more deactivation policies in the deactivation function list area for selection when the skylight function is deactivated later.

[0054] 2. Information control solution.

[0055] (1) Information deactivation processing method.

[0056] Design customized information deactivation methods according to the four processing methods of information by the application server and the station extension, namely forwarding, broadcasting, regeneration, and splicing.

[0057] There are fixed target addresses in the forwarding and splicing information packets, and the information source waits for the target subsystem to return a receipt message after sending such information. To ensure the integrity of the process of such information, perform failure processing on it. The failure processing method is to modify the function code field to an invalid value according to the line dispatcher service deactivation policy, without changing its information transmission path and type.

[0058] The information source of the broadcast type does not need to receive the target subsystem receipt, and the broadcast information occupies more channel resources. Therefore, the deactivation processing method for this type of information according to the line dispatcher service deactivation policy is truncation, stopping subsequent transmission.

[0059] The regeneration type of information involves multiple target addresses after regeneration. According to the line dispatcher service deactivation policy (specifically the deactivation range), delete the deactivated subsystem ID (identifier) in the target field, that is, narrow the sending range of the information according to the deactivation range. The subsystem ID is the unique identification code in the CTC system, identified by a 4-digit decimal number.

[0060] (2) Information control method during the high-speed railway skylight.

[0061] During non-sky window periods, both levels of the information control subsystem's system modules are in a silent state, and their own states do not affect the CTC system's services, nor do they reduce the CTC security level or system availability. During sky window periods, 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 rules during non-sky window periods, and then transmits it to the information control center module; the information control center module performs deactivation processing on the information and sends it out according to the target address except for the broadcast information that has been truncated.

[0062] As Figure 3 shown, it demonstrates the information flow and control schematic diagram within the high-speed railway sky window. The information input to the application server includes: information sent from the dispatching desk, adjacent dispatching desks, external interfaces, etc., which is called central source information. To maintain the completeness of the application server's own services and the integrity of log records, the information control center module is connected in series at the output end of the application server. All central source information is directly input into the application server according to the information transfer mode during non-sky window periods. The application server forwards, broadcasts, regenerates, and splices it according to the rules during non-sky window periods, and then enters the information control center module for deactivating information processing. After being processed by the information control center module for deactivation, except for the truncated broadcast information, it is sent by the information control center module to the application server (that is, only the forwarded, spliced, and regenerated information after deactivation processing is sent at this time), and the application server sends it to other central subsystems or stations according to the target address.

[0063] Divided according to the information destination, the central source information includes three categories: in-station information, inter-station information, and information reported to the center. Based on the objective situation of limited computing resources of the station subsystem, a large number of stations, and limited wide area network bandwidth resources, a station information control method is designed based on the principles of saving computing and network resources and decentralized processing, as follows:

[0064] All in-station information is sent from the extension to the information control station module. After deactivation processing, it is sent to other in-station subsystems to avoid the ineffective occupation of resources of in-station subsystems by broadcast information; the information from other in-station subsystems to the station extension is transmitted in the original way.

[0065] All information reported to the center is sent from the extension to the information control station module. After deactivation processing, it is reported to the center to avoid the occupation of the wide area network channel bandwidth by the deactivated broadcast information. At the same time, the goal of decentralized processing of station information is achieved, and the risk of resource congestion caused by the centralized processing of a large number of station deactivation information by the central module is avoided.

[0066] The information transmitted between stations is grouped according to forwarding, splicing types and broadcasting, rebirth types. The control measures for forwarding and splicing type information are invalidation processing. To avoid expanding the scope of invalidation processing, the inter-station extension directly transmits 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 processing. The control measures for broadcasting and rebirth type information are truncation and narrowing the target range respectively. The station extension of the information sending station sends it to the corresponding information control station module for invalidation processing, which can reduce the occupation of the inter-station wide area network channel resources.

[0067] In the embodiment of the present invention, under the high-speed railway skylight, the information control center module mainly deactivates various types of information (center source information) sent by the application server. Among them, 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 deactivates the information (station source) sent by the station extension. In this process, the station extension will receive some information that has been deactivated by the information control center module, and these information do not need to be deactivated again.

[0068] 3. Communication protocol design.

[0069] In the embodiment of the present invention, the content of the information packet is modified for the deactivated information, and the communication protocol is expanded. Specifically: for the invalidation processing of forwarding and splicing type information, and for the narrowing of the target range processing of rebirth type information, the content of the information packet needs to be modified, and the communication protocol is expanded and modified. As shown in Table 1, the expanded communication protocol includes two additional fields, validity and information processing type, in addition to the existing communication protocol fields. Among them, the validity field is used to indicate whether the deactivated information is processed according to the normal business logic or only as a heartbeat message. For example, when the value of the validity field is 1, the information receiving subsystem (collectively referred to as a series of subsystems that receive information) processes the information according to the normal logic; when the value of the validity field is 2, the information receiving subsystem only uses it as a heartbeat message and does not process business data; the information processing type includes forwarding, broadcasting, rebirth and splicing. After the application server processes the information according to fixed rules, it fills in the information in this field, supporting the CTC information control subsystem to perform information truncation, narrowing the target range or function invalidation processing in the manner described above.

[0070] Table 1: Expanded communication protocol

[0071]

[0072] The above solution provided by the embodiments of the present invention is designed for the refined deactivation requirements of train operation dispatching services during skylight periods. An information control subsystem based on CTC information control is designed, which includes two-level modules. The information control center module has the function of information deactivation policy management, and the refined service deactivation function is realized through the cooperation of the two-level modules. In addition, the information processing methods of the application server and the station extension are combined, namely forwarding, broadcasting, regeneration, and splicing, to design targeted information deactivation control measures, which can 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 the control service deployment.

In actual applications, the above functions can be allocated to different functional modules according to needs, that is, the internal structure of the system is divided into different functional modules to complete all or part of the functions described above.
