Train cross-border operation control authority handover method and system, and device and medium

Abstract

Provided in the present invention are a train cross-border operation control authority handover method and system, and a device and a medium. The method comprises: acquiring balise group information of a country A, and by means of the balise group information of the country A and balise group information of a country B, determining the switching from a second mode ETCS-2 to a first mode ETCS-1, which is referred to as E1 switching, and the switching from the first mode ETCS-1 to the second mode ETCS-2, which is referred to as E2 switching; and by means of the switching from the second mode ETCS-2 to the first mode ETCS-1 and the switching from the first mode ETCS-1 to the second mode ETCS-2 in an authority handover mode, obtaining a movement authority (MA) of the country B. It can be seen therefrom that two processes of E1 switching and E2 switching are used to complete a train control authority handover, and the two processes are performed in parallel, thereby improving the reliability and safety of a system. Handover processes in two directions do not interfere with each other, and handover points in the two directions are not unique, and thus ground devices can be arranged in a staggered manner, thereby improving the cross-border operation efficiency. RBCs of two countries do not need an information exchange, and thus secure information transmission between systems of the two countries is reduced, thereby improving the usability of a design solution.

Description

Method, system, device and medium for transferring cross-border train operation control authority Technical Field

[0001] The present invention belongs to the technical field of cross-border train operation, and in particular relates to a method, system, equipment and medium for transferring control authority for cross-border train operation. Background Art

[0002] ETCS, the European Train Control System, is currently widely used in railway projects between EU member states. The ETCS-2 train control mode, with its enhanced availability, reliability, and safety, has gained widespread global adoption. For trains operating across international borders, train control authority is typically transferred using a Rail-to-Cable (RBC) transfer.

[0003] However, since national border areas are geographically located at the junction of administrative regions of various countries, the operating scenarios are relatively complex. In addition, the border areas are covered by the GSM-R networks of both countries, resulting in significant signal interference, which can easily lead to failures in the transfer of train control authority, resulting in trains stopping in border areas. This is also one of the situations that transportation management departments of various countries are trying their best to avoid.

[0004] Furthermore, the ETCS-2 train control system is often used on high-speed railway lines. To avoid excessive data processing and inter-system interactions, the train control authority transfer process is typically completed within the section. However, the inter-station sections near the border between two countries are often not long enough to maintain high train speeds for the transfer. Reducing train speeds would significantly reduce line transportation efficiency.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0060] It should be noted that the terms "first", "second" etc. in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the application described herein. In this application, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "center", "vertical", "horizontal", "lateral", "longitudinal" etc. are based on the directions or positional relationships shown in the accompanying drawings.

[0061] The present invention proposes a method, system, device, and medium for transferring control authority for cross-border train operations. These methods can reduce the likelihood of trains stopping due to control authority transfer failures at national borders and improve the efficiency of cross-border train operations within a railway network.

[0062] An embodiment of the present invention provides a method for transferring control authority for cross-border train operation, as shown in FIG1 , including:

[0063] S101: While the train is traveling in the section between countries A and B, it obtains information about the balise groups of countries A and B and determines an authority transfer mode based on the information about the balise groups of countries A and B. The authority transfer mode includes: switching from the second mode ETCS-2 to the first mode ETCS-1 and switching from the first mode ETCS-1 to the second mode ETCS-2.

[0064] S102: Obtaining country B mobile authorization MA by switching the second mode ETCS-2 to the first mode ETCS-1 and the first mode ETCS-1 to the second mode ETCS-2 in the authority transfer mode.

[0065] It's important to note that in Europe, due to the early incompatibilities and lack of uniformity in the use of train control systems across different countries, trains crossing borders into neighboring countries had to stop and switch control systems, resulting in inefficient interoperability between trains within the European railway network. To address this, the UN ISIG, formed by major European signaling companies, developed the unified ERTMS (European Rail Transport Traffic Management System) and European Rail Traffic Management System (ETCS) technical specifications. In 2001, the European Union legislated the European Train Control System (ETCS), making it a mandatory technical specification for EU member states to follow when carrying out railway construction.

[0066] The existing ETCS-2 through-train solution adheres to Subset-039 FIS for the RBC / RBC Handover in the ETCS specification set. It implements cross-border train operation control via RBC handover, hereinafter referred to as "E2 through-train." As shown in Figures 2 and 3, assume that stations A and B belong to two countries, respectively, with the national border located within the interval between the two stations. S and H are the approach signals for stations A and B, respectively, and trains utilize the ETCS-2 train operation control mode within both countries. This article only illustrates the scenario of a train traveling from station A to station B and the ground equipment associated with the handover of train control authority. The principles for reverse operation are the same, so this will not be further elaborated.

[0067] In ETCS-2 mode, the Radio Block Center (RBC), the train control ground equipment, generates a Move Authority (MA), which is then transmitted to the train via wireless transmission via the Global System for Mobile Communications–Railway (GSM-R) network, and combined with ground passive transponders to control train operation.

[0068] As shown in Figure 3, stations A and B are under the jurisdiction of their respective national RBCs, with station A’s RBC being the transferor, denoted as RBC HOV ; Station B RBC is the receiver, recorded as RBC ACC Information exchange between RBCs is achieved through a signal security data network. GSM-R A For Country A's wireless network, GSM-R B This is the wireless network of country B. Both networks cover stations in the other country.

[0069] In ETCS-2 mode, when a train travels from station A to station B, the train control authority transfer process is as follows.

[0070] When the train passes the registered transponder group GRE, it obtains the railway integrated digital mobile communication system GSM-R of country B. B Network coding, from onboard equipment to railway integrated digital mobile communication system GSM-R B Initiate a registration request and execute subsequent processes after successful registration.

[0071] When the train passes RE, it obtains the RBC of the radio block center of country B. ACC Equipment code, from the vehicle equipment to the radio block center receiving RBC ACC Initiate a connection request and execute subsequent processes after the connection is successful.

[0072] When the train passes the balise RA, the radio block centre in country A transfers the balise to the RBC. HOV To the RBC receiver in Country B ACC Initiate the handover process, Country A's Radio Block Center transfers to RBC HOV Generate a mobile authorization MA extending to the territory of country B;

[0073] When the train passes the balise group RN, the train executes the RBC handover instruction and disconnects the RBC handover party from the radio block center of country A. HOV The train is connected by the radio block center RBC in country B. ACC The takeover and transfer of train control authority are completed.

[0074] In order to improve the efficiency of train passage at the border between two countries, reduce the probability of train stopping in the border area, and ensure that trains can operate in the ETCS-2 control mode at a higher speed between the two countries, the present invention is proposed under the premise of meeting the ETCS technical specifications.

[0075] In some optional embodiments, switching from the second mode ETCS-2 to the first mode ETCS-1 includes:

[0076] S21: When the train passes through the advance notice balise group LTA1 that is switched to ETCS-1, the train obtains the switching notice information of the advance notice balise group LTA1 that is switched to ETCS-1;

[0077] S22: According to the changeover notice information, the train obtains the level changeover command and continues to use the RBC of country A. A Issue a movement authorization MA to the train.

[0078] S23: According to the RBC of Country A AA movement authorization MA is issued to the train, and the transponder group sends a level conversion message to the train;

[0079] When the train passes through the execution transponder group LTO1 converted to ETCS-1, the execution information of the execution transponder group LTO1 converted to ETCS-1 is obtained;

[0080] According to the execution information of the transponder group LTO1 for switching to ETCS-1, the level switching command is executed, the train control mode is switched from ETCS-2 to ETCS-1, and the switching from the second mode ETCS-2 to the first mode ETCS-1 is completed.

[0081] S24: Train passes active balise group BH infill When the mobile authorization MA is obtained within the territory of country B, the mobile authorization MA is obtained with the station B entrance signal H as the starting point.

[0082] S25: When the train passes the active balise group BH, the train receives the ground equipment movement authorization MA.

[0083] The present invention combines the respective advantages of ETCS-2 and ETCS-1 systems, and adopts both ETCS-2 and ETCS-1 control modes to control train operation during the train control authority transfer process. While ensuring that the RBCs of the two countries do not exchange safety information, the train can pass through the border area between the two countries without stopping.

[0084] The following describes in detail the operation process of switching from the second mode ETCS-2 to the first mode ETCS-1.

[0085] Refer to Figure 4. A train departs from station A to station B. The transfer of train control authority between stations A and B is done through "ETCS-2 → ETCS-1", hereinafter referred to as "E1 handover". A radio block center RBC is set up in each country. A and Country B Radio Block Center RBC B , Country A Radio Block Center RBC A With Country B's Radio Block Center (RBC) B They control the ETCS-2 trains within their respective jurisdictions separately without exchanging information, thus achieving safety information isolation.

[0086] When the train passes the balise group LTA1 that has been switched to ETCS-1, it obtains the level switching notice information of the balise group LTA1 that has been switched to ETCS-1 and continues to use the radio block center RBC of country A. A Issue movement authorization MA to the train;

[0087] When the train passes the balise group LTO1 that switches to ETCS-1, the train executes the level switching command and the train control mode switches from ETCS-2 to ETCS-1.

[0088] The train passes the active balise group BH infill When the mobile authorization MA is obtained in advance within country B with the station B entrance signal H as the starting point;

[0089] When the train passes the active balise group BH, it receives the ground equipment movement authorization MA normally.

[0090] In some optional embodiments, switching from the first mode ETCS-1 to the second mode ETCS-2 includes:

[0091] S31: When the train passes the registered transponder group GRE, it obtains the railway integrated digital mobile communication system GSM-R of country B. B Network coding;

[0092] Through the onboard equipment to the B country railway integrated digital mobile communication system GSM-R B Initiate a registration request;

[0093] After the connection request is approved, the train is connected to the GSM-R integrated digital mobile communication system of Country B. B network.

[0094] S32: When the train passes the connected balise group RE, it obtains the radio block center RBC of country B. B Equipment coding, according to the radio block center RBC B Equipment coding vehicle equipment to RBC B Initiate a connection request;

[0095] After the connection request is approved, register with the Radio Block Center (RBC) of Country B. B .

[0096] S33: When the train passes the balise group LTA2 that is switched to ETCS-2, the train will head towards the radio block center RBC in country B. B Report current location;

[0097] Radio Block Centre (RBC) in Country B B The train is provided with a movement authorization MA, and the balise group sends a level switching message to the train.

[0098] S34: When the train passes the transponder group LTO2 that switches to ETCS-2, the train receives the ground equipment movement authorization MA, the train executes the level conversion command, and the train control mode is changed from ETCS-1 to ETCS-2.

[0099] The following describes in detail the operation process of switching from the first mode ETCS-2 to the second mode ETCS-2.

[0100] Refer to Figure 4. When a train departs from station A to station B, the control authority between stations A and B is transferred via "ETCS-1 / 2 → ETCS-2", hereinafter referred to as "E2 handover". A radio block center RBC is set up in each country. A and Country B Radio Block Center RBC B , Country A Radio Block Center RBC A With Country B's Radio Block Center (RBC) B They control the ETCS-2 trains within their respective jurisdictions separately without exchanging information, thus achieving safety information isolation.

[0101] When the train passes the registered transponder group GRE, it obtains the railway integrated digital mobile communication system GSM-R of country B. B Network coding, from the onboard equipment to the railway integrated digital mobile communication system GSM-R of Country B B Initiate a registration request;

[0102] When the train passes through the connected balise group RE, it obtains the radio block center RBC of country B. B Equipment code, from the vehicle equipment to RBC B Initiate a connection request and execute subsequent processes after the connection is successful;

[0103] When the train passes the balise group LTA2 which is switched to ETCS-2, the train will send the signal to the radio block center RBC of country B. B Reporting current position, Radio Block Center (RBC) of Country B B Provide movement authorization MA to the train and obtain level conversion information from the balise group;

[0104] When the train passes the transponder group LTO2 that switches to ETCS-2, the train executes the level conversion command and the train control mode changes from ETCS-1 to ETCS-2.

[0105] In the present invention, a train travels from station A to station B. It obtains movement authorization MA between countries A and B, with the station entry signal H at country B as its endpoint, and then enters the border area between the two countries. During the train control authority transfer process, both E1 and E2 handover processes are performed simultaneously.

[0106] In some optional embodiments, referring to FIG. 5 , the present invention adopts two processes: E1 switching and E2 switching.

[0107] During the E2 switching process, the distance between the registration balise group GRE and RA should be greater than the distance a train travels at the maximum design speed of the line for 40 seconds; the distance between RA and the advance balise group LTA2 converted to ETCS-2 should be greater than the distance a train travels at the maximum design speed of the line for 20 seconds; the distance between the advance balise group LTA2 converted to ETCS-2 and the execution balise group LTO2 converted to ETCS-2 should be greater than the distance a train travels at the maximum design speed of the line for 20 seconds.

[0108] During the E1 handover process, the distance between the advance balise group (LTA1) switching to ETCS-1 and the execution balise group (LTO1) switching to ETCS-1 should be greater than the distance a train would travel for 5 seconds at the line's maximum design speed. When bidirectional operation is adopted within the section, this solution does not impose special requirements on the location of the transfer of train control authority in both directions; that is, the ground balise groups in both directions can be arranged in an intersecting manner.

[0109] The existing E2 through-train solution has certain limitations in practical engineering applications. Because the E2 through-train solution is implemented through RBC transfer, according to ETCS specifications (see Figure 8), the distance between GRE and RA should be greater than the distance a train travels at the line's maximum design speed for 40 seconds; the distance between RA and RE should be greater than the distance a train travels at the line's maximum design speed for 20 seconds; and the distance between RE and RN should be greater than the distance a train travels at the line's maximum design speed for 20 seconds. When bidirectional operation is employed in a section, the existing solution requires that train control transfer occur at the same location in both directions.

[0110] According to the design scheme of the present invention, under the scenario where the design operating speed is 250km / h and the requirements for train control authority transfer are met in both directions, the design length of the section can be greater than 5.56km.

[0111] In high-speed railway lines that use the ETCS-2 train control system, in order to avoid unnecessary system errors caused by excessive data interaction, the train control authority transfer process is usually required to be completed between stations, and the inter-station sections in border areas between different countries are usually shorter. This results in the cross-border operation speed of trains being limited to an extremely low level when the existing E2 through-train solution is applied, which has a great impact on the transportation efficiency of cross-border trains. In the present invention, the layout principle of the ground transponder group is relatively simple, and since the ground transponder groups RBC of both parties do not directly exchange information, the location of the train control authority transfer point is flexible, and the transfer area is required to be smaller, which can be applied to more complex cross-border operation scenarios in actual engineering applications.

[0112] The existing E2 interconnection solution uses a single RBC transfer method to transfer train control authority. As shown in Figure 6, if any link in the RBC transfer process fails or related equipment malfunctions, the RBC transfer process will fail, causing the train to stop at the border area between the two countries.

[0113] This invention incorporates two simultaneous processes, E1 and E2, within the control transfer area. As shown in Figure 7, if either process fails or related equipment malfunctions, the other process can still execute normally, ensuring the smooth passage of trains across national borders. Furthermore, because both processes are designed as level-shifting behaviors, there is no need for security information exchange between the two countries' RBCs. Compared to existing E2-based solutions, this approach offers broader application prospects.

[0114] Based on the same inventive concept, another embodiment of the present invention further provides a system for transferring control authority for cross-border train operation, as shown in FIG9 , comprising:

[0115] The acquisition unit 201 is configured to acquire balise group information of countries A and B while the train is traveling in the section between countries A and B, and determine an authority transfer mode based on the balise group information of countries A and B. The authority transfer mode includes: switching from the second mode ETCS-2 to the first mode ETCS-1 and switching from the first mode ETCS-1 to the second mode ETCS-2.

[0116] The switching unit 202 is configured to obtain a country B mobile authorization MA by switching from the second mode ETCS-2 to the first mode ETCS-1 and from the first mode ETCS-1 to the second mode ETCS-2 in the authority transfer mode.

[0117] This invention uses a dual process, E1 and E2, to transfer train control authority. These two processes operate in parallel, improving system reliability and security. Furthermore, the two-way handover process does not interfere with each other, and the handover points are not unique, enabling the cross-deployment of ground equipment and improving cross-border operational efficiency. Furthermore, information exchange between the two RBCs is eliminated, reducing the transmission of security information between the two systems and improving the design's usability.

[0118] The present invention offers practical improvements over existing technologies: 1. Operational scenarios at national borders are complex. Existing solutions only use RBC handover to transfer train control authority, significantly increasing the probability of handover failure. The solution provided by the present invention simultaneously performs both E1 and E2 handover processes. When the handover process is successfully completed, ETCS-2 control mode is prioritized. Even if either process fails, the train can automatically enter the corresponding control mode through the other process, ensuring that the train can pass through the national border without stopping.

[0119] 2. The existing solutions have fixed requirements for the layout of ground transponder equipment, and the required handover area is large, which has many restrictions on its use in actual engineering applications. The solution provided by the present invention has fewer restrictions on the layout of ground transponder equipment, and the transponder groups used in different directions and different processes can be cross-arranged, and the required handover area is small. Due to the particularity of cross-border operation scenarios, the handover process is required to be completed within the interval, and the scope of the handover area directly affects the cross-border travel efficiency of trains. The design solution of the present invention can ensure that the train completes the train control authority handover process at a higher operating speed within the smallest handover area, thereby achieving efficient cross-border operation.

[0120] 3. In the existing scheme, if we want to adopt the RBC transfer implementation method, we must transfer the RBC HOV With RBC ACC Direct communication is established between the two systems, and a large amount of safety information is exchanged during the transfer of train control authority. The design proposed in this invention achieves interoperability of the ETCS-2 control mode through two level conversions, eliminating the need for information exchange between the two RBCs. This system is relatively simple to implement, reduces the secondary development work required for interfaces between the internal and external signaling systems during project implementation, and enhances technical feasibility.

[0121] Based on the same inventive concept, another embodiment of the present invention further provides an electronic device 161, as shown in FIG10 , including a processor 164, a communication interface 165, a memory 162, and a communication bus, wherein the processor 164, the communication interface 165, and the memory 162 communicate with each other via the communication bus;
