Description

Technical Field

[0001] The present invention relates to the field of train control and information interaction, and in particular to a method for supporting virtual marshaling information interaction between TSRS and a temporary speed limit server. Background Art

[0002] Virtual marshaling is a hot topic in the current research of train operation control systems in the world. In traditional mobile block technology, the authorization point of the rear train is the rear position of the front train. Through virtual marshaling technology, this limitation can be effectively broken through. The rear train can further shorten the tracking interval based on the relative distance and comprehensive consideration of the speed, acceleration and other information of the front train. Only trains within the marshaling can break through the limitations of the "hard" wall. Through virtual marshaling technology, multiple independent trains can be connected not through physical couplers, but through car-to-car communication and invisible "virtual" couplers, and run as one train with the shortest tracking interval.

[0003] The virtual marshaling plan can be used to specify which trains are marshaled into a virtual train. The virtual marshaling plan describes which trains are marshaled into a virtual train. In scenarios such as national railways and freight railways, the lines are long and the equipment jurisdiction is limited. When virtual trains run across boundaries, it is necessary to exchange virtual marshaling plan information between different equipment jurisdiction boundaries to support virtual marshaling trains to obtain marshaling information in advance when running across devices, or to quickly restore the marshaling operation status in the event of a fault. By transmitting virtual marshaling plan information between devices, trains can be smoothly transitioned and seamlessly connected between different devices, improving the overall system operation efficiency.

[0004] The temporary speed limit server is the core equipment of the train control system of my country's CTCS (China Train Control System), responsible for the management and issuance of information such as temporary speed limits and operation plans. As an operation plan, the virtual marshaling plan should be managed uniformly by the temporary speed limit server (TSRS for short). Therefore, it is necessary to propose a method for exchanging virtual marshaling plan information between TSRS. Summary of the invention

[0005] The purpose of the present invention is to propose a method for exchanging virtual marshaling plan information between TSRS, so that when a virtual train runs across boundaries, TSRS can exchange virtual marshaling plan information between jurisdiction boundaries, support virtual marshaling trains to obtain marshaling information in advance when running across devices, or quickly restore the marshaling operation status in the event of a fault de-marshaling.

[0006] To achieve the above object, the present invention proposes a method for supporting the exchange of virtual grouping information between TSRSs, comprising the following steps:

[0007] S1. The local TSRS receives virtual grouping plan information from the corresponding dispatching device;

[0008] S2. The local TSRS sends the virtual marshaling plan information to the train in the virtual marshaling plan or the adjacent TSRS to which the train belongs;

[0009] S3, the adjacent TSRS sends the virtual marshaling plan information to the trains within its jurisdiction and appearing in the virtual marshaling plan information;

[0010] S4. After receiving the virtual marshaling plan information, the trains within the jurisdiction of the adjacent TSRS establish communication with the trains in the same virtual train according to the virtual marshaling plan information and start marshaling based on the train-to-train communication.

[0011] Optionally, step S2 further includes the following steps:

[0012] S21, the local TSTS and the adjacent TSRS exchange the vehicle information under their respective jurisdiction;

[0013] S22. The local TSRS issues the virtual marshaling plan to the trains in the virtual marshaling plan within the local jurisdiction;

[0014] S23. When the local TSRS finds that all trains in the virtual marshaling plan are not within the local jurisdiction, and through interaction with the adjacent TSRS, it is found that the adjacent TSRS contains a train in the virtual marshaling plan and the train is not in the virtual marshaling mode, the virtual marshaling plan information is sent to the adjacent TSRS.

[0015] Optionally, the step S21 is specifically as follows: the train sends its own vehicle information to the corresponding TSRS; and adjacent TSRSs exchange information of vehicles located in the boundary area.

[0016] Optionally, the vehicle information includes: train identification information, train IP address information, and train operation mode information; the train operation mode information includes the virtual formation status of the train.

[0017] Optionally, the size of the boundary area is flexibly configured according to needs and the actual processing capability of the TSRS.

[0018] Optionally, when the local TSRS finds that all trains in the virtual marshaling train are in a virtual marshaling success state, it stops sending virtual marshaling plan information to adjacent TSRSs.

[0019] Optionally, when the local TSRS finds that a train in the virtual marshaling plan that was originally under the jurisdiction of an adjacent TSRS is neither under the jurisdiction of the local TSRS nor under the jurisdiction of an adjacent TSRS, it stops sending virtual marshaling plan information to the adjacent TSRS.

[0020] Optionally, after the scheduling device cancels the original virtual grouping plan, the local TSRS stops sending the virtual grouping information to the adjacent TSRS.

[0021] Optionally, for a successfully formed virtual train, when the formation is cancelled due to a fault, if all trains in a virtual train are within the same TSRS range, the dispatching equipment corresponding to the TSRS shall formulate a formation plan and directly perform the formation; if the train is within the range of two adjacent TSRSs, the TSRS corresponding to the party formulating the virtual formation plan shall execute steps S1-S5, wherein the TSRS corresponding to the party formulating the virtual formation plan is the local TSRS.

[0022] Optionally, the local TSRS periodically receives virtual marshaling plan information from the corresponding dispatching device; the local TSTS and the adjacent TSRS periodically exchange vehicle information respectively governed by them; and the train periodically sends its own vehicle information to the corresponding TSRS.

[0023] Optionally, the dispatching device sends virtual marshaling plan information to the local TSRS. After receiving the virtual marshaling plan information, the local TSRS sends a receipt to the dispatching device. Thereafter, the dispatching device will not send the virtual marshaling plan information to the local TSRS again until the virtual marshaling plan information changes. The local TSTS exchanges vehicle information under the jurisdiction of an adjacent TSRS and sends a receipt after receiving the other party's information. The vehicle information will not be sent to the other party again until the vehicle information changes. The train sends its own vehicle information to the corresponding TSRS. After receiving the information, the TSRS sends a receipt to the train. The train will not send information to the TSRS again until the vehicle information of the train changes.

[0024] The present invention also proposes a temporary speed limit server that supports the exchange of virtual marshaling information between TSRS, which is used in the above method. The temporary speed limit server receives the virtual marshaling plan information prepared by the dispatching device, and issues the virtual marshaling plan information to the relevant trains and feeds back the execution status of the virtual marshaling plan to the dispatching device; the temporary speed limit server also exchanges virtual marshaling plan information and train vehicle information within its jurisdiction with adjacent temporary speed limit servers.

[0025] Compared with the prior art, the present invention has the following innovative features and beneficial effects:

[0026] Based on the functions of the existing temporary speed limit server, this solution adds the function of transparently transmitting virtual marshaling information between adjacent TSRSs; it can effectively support the scenario of virtual marshaling trains running across TSRSs, support the scenario of virtual marshaling trains being de-marshaled due to faults between TSRSs, and support the scenario of each train in the virtual marshaling train belonging to different TSRSs for marshaling;

[0027] Based on the functions of the existing TSRS, this solution adds virtual marshaling operation plan management, making it more adaptable and applicable to longer railway lines, not limited to the jurisdiction of a TSRS.

[0028] This solution is developed based on existing equipment and does not require the addition of new equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the embodiments of the present invention Figure 1-2 , the technical solutions, structural features, objectives achieved and effects in the embodiments of the present invention are described in detail.

[0032] It should be noted that the drawings are in a very simplified form and use non-precise proportions.

Therefore, they have no substantive technical significance.

[0033] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] A method for supporting the exchange of virtual grouping plan information between TSRS, such as Figure 1 and Figure 2 As shown, the following steps are included:

[0035] S1. The local TSRS periodically receives virtual grouping plan information from the corresponding scheduling device;

[0036] After a virtual marshaling plan is prepared on a local dispatching device, such as CTC (railway dispatching centralized system), CTC periodically sends the plan to the corresponding local TSRS.

[0037] For example, there are trains 1 and 2 within the jurisdiction of the local TSRS, and there is train 3 within the jurisdiction of the adjacent TSRS and train 3 is in its boundary area; the virtual marshaling plan issued by CTC and received by the local TSRS indicates that the adjacent trains 1, 2, and 3 are a virtual train.

[0038] S2. The local TSRS sends the virtual marshaling plan information to the train in the virtual marshaling plan or the adjacent TSRS to which the train belongs;

[0039] S21. The local TSTS and the adjacent TSRS periodically exchange the vehicle information respectively governed by them. Specifically, the train periodically sends its own vehicle information to the corresponding TSRS; the TSRSs periodically exchange the information of vehicles located in the boundary area.

[0040] The vehicle information includes: train identification information, train IP (Internet Protocol) address information (including necessary gateway information required for IP communication), and train operation mode information. The train operation mode information includes the virtual marshaling state of the train.

[0041] The size of the boundary area can be flexibly configured according to needs and the actual processing capability of the TSRS.

[0042] In this embodiment, since the trains in a virtual train must be adjacent, when train 3 is in the boundary area of ​​the corresponding TSRS, train 2 is in the boundary area of ​​the local TSRS. The local TSRS and the adjacent TSRS periodically exchange vehicle information in the boundary area, that is, the adjacent TSRS transmits the information of train 3 to the local TSRS, and the local TSRS transmits the information of vehicles in the boundary area (train 2, or when train 1 is also in the boundary area of ​​the local TSRS, it refers to train 2 and train 1) to the adjacent TSRS.

[0043] S22. The local TSRS issues the virtual marshaling plan to the trains in the virtual marshaling plan within the local jurisdiction. Specifically, the local TSRS can obtain the train information within the local jurisdiction by periodically sending its own vehicle information to the corresponding TSRS. Therefore, after receiving the virtual marshaling plan information, the local TSRS issues the virtual marshaling plan information to the local trains with which communication has been established normally (i.e., the train periodically sends its own vehicle information to the corresponding TSRS).

[0044] S23. When the local TSRS finds that all trains in the virtual marshaling plan are not within the local jurisdiction, and through interaction with the adjacent TSRS, it is found that the adjacent TSRS contains a train in the virtual marshaling plan and the train is not in the virtual marshaling mode, the virtual marshaling plan information is sent to the adjacent TSRS.

[0045] In this embodiment, after receiving the virtual marshaling plan information, the local TSRS sends the virtual marshaling plan information to Train 1 and Train 2, as well as adjacent TSRSs.

[0046] S3. After receiving the virtual marshaling plan information sent by the local TSRS, the adjacent TSRS checks whether the train in the plan has established communication with the adjacent TSRS. If communication has been established, the virtual marshaling plan information is sent to the corresponding train within the jurisdiction, that is, the adjacent TSRS sends the virtual marshaling plan information to Train 3. At the same time, the local TSTS and the adjacent TSRS periodically exchange the vehicle information in the boundary area under their respective jurisdiction, and the adjacent TSRS can obtain the vehicle information in the boundary area of ​​the local TSRS. When the adjacent TSRS sends the virtual marshaling plan information to Train 3, it also sends the vehicle information in the boundary area of ​​the local TSRS to Train 3, and the vehicle information in the boundary area of ​​the local TSRS includes the vehicle information of Train 2.

[0047] S4. After receiving the virtual marshaling plan information and the vehicle information in the local TSRS boundary area, train 3 within the jurisdiction of the adjacent TSRS establishes communication with the adjacent train in the same virtual train, i.e., train 2, according to the virtual marshaling plan information, and starts marshaling based on vehicle-to-vehicle communication.

[0048] S5. When all trains in the virtual marshaling plan are successfully marshaled, or the marshaling plan is cancelled, or a train is not within the jurisdiction of the local TSRS or the adjacent TSRS, the local TSRS stops sending virtual marshaling plan information to the adjacent TSRS, including the following situations:

[0049] S51. When the local TSRS finds that all trains in the virtual marshaling train are in a virtual marshaling success state, it stops sending virtual marshaling plan information to adjacent TSRSs;

[0050] Specifically, after the marshaling is successful, the virtual marshaling status in the vehicle information of Train 1, Train 2, and Train 3 all become a virtual marshaling success status, and the train periodically sends its own vehicle information to TSRS, and the virtual marshaling success status is directly transmitted to the local TSRS or transmitted to the local TSRS through an adjacent TSRS. The local TSRS obtains the information that Train 1, Train 2, and Train 3 have all been successfully marshaled. At this time, the local TSRS no longer sends virtual marshaling plan information to the adjacent TSRS, and sends marshaling success information to CTC.

[0051] S52, when the local TSRS finds that a train in the virtual marshaling plan that was originally under the jurisdiction of the adjacent TSRS is neither under the jurisdiction of the local TSRS nor under the jurisdiction of the adjacent TSRS, it stops sending the virtual marshaling plan information to the adjacent TSRS;

[0052] Specifically, when a train within the jurisdiction of an adjacent TSRS leaves the jurisdiction of the local TSRS and the adjacent TSRS, that is, the local TSRS cannot obtain the vehicle information of the train by interacting with the adjacent TSRS, nor can it directly receive its own vehicle information sent by the train, it is deemed that the train has left the jurisdiction of the local TSRS and the adjacent TSRS, and the local TSRS will no longer send virtual marshaling plan information to the adjacent TSRS.

[0053] In this embodiment, for example, when the train 3 leaves the jurisdiction of the adjacent TSRS and is not within the jurisdiction of the local TSRS, the local TSRS stops sending virtual marshaling information to the adjacent TSRS.

[0054] S53. When CTC cancels the original virtual grouping plan, the local TSRS stops sending the virtual grouping information to the adjacent TSRS. Since CTC periodically sends virtual grouping plan information to the local TSRS, when the local TSRS cannot receive the virtual grouping plan information sent by CTC, the local TSRS stops sending the virtual grouping information to the adjacent TSRS.

[0055] Furthermore, for a successfully marshaled virtual train, if the marshaling is cancelled due to a fault (i.e., through the interaction between TSRSs, it is found that a train in a virtual train is not in a successful virtual marshaling state), at this time, if all trains in a virtual train are within the same TSRS range, the CTC corresponding to the TSRS will draw up a marshaling plan and directly perform marshaling; if the marshaled train is within the range of two adjacent TSRSs, the TSRS corresponding to the virtual marshaling plan drafter will execute the above steps S1-S5, wherein the TSRS corresponding to the virtual marshaling plan drafter is the local TSRS.

[0056] It should be noted that the information sending cycle in the present invention, such as the local TSRS periodically receiving the virtual formation plan information from the corresponding scheduling device, the local TSTS and the adjacent TSRS periodically interacting with each other for the vehicle information respectively governed by the two, and the train periodically sending its own vehicle information to the corresponding TSRS, the specific cycle duration is set according to needs, and the above three cycles may be the same or different.

[0057] In other embodiments, information transmission may also adopt a receipt mode, that is, the dispatching device sends virtual grouping plan information to the local TSRS, and the local TSRS sends a receipt to the dispatching device after receiving the virtual grouping plan information, and then the dispatching device will not send the virtual grouping plan information to the local TSRS again until the virtual grouping plan information is changed; the local TSTS exchanges the vehicle information under the jurisdiction of the adjacent TSRS, and sends a receipt after receiving the other party's information, and will not send the vehicle information to the other party again until the vehicle information changes; the train sends its own vehicle information to the corresponding TSRS, and the TSRS sends a receipt to the train after receiving it, and will not send information to the TSRS again until the vehicle information of the train changes.

[0058] The present invention also has the function of automatically acquiring the marshaling plan according to the vehicle's marshaling information: considering that the marshaling fleet may run long distances and run to an area that is completely unconnected with the dispatching desk, at this time, the TSRS in charge can automatically identify the inter-vehicle marshaling plan information according to the vehicle's marshaling information, and has the function of automatic reissue after the vehicle is abnormally de-marshaled; or, send the information to the dispatching equipment for manual confirmation whether to continue to maintain the vehicle marshaling status.

[0059] The present invention also provides a temporary speed limit server (TSRS) supporting the exchange of virtual marshaling information between TSRS, which is used in the above-mentioned method for supporting the exchange of virtual marshaling plan information between TSRS. The temporary speed limit server receives the virtual marshaling plan information drafted by the CTC, and issues the virtual marshaling plan information to relevant trains and feeds back the execution status of the virtual marshaling plan to the CTC; the temporary speed limit server also exchanges virtual marshaling plan information and train vehicle information within its jurisdiction with adjacent temporary speed limit servers.

After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur.
