Description

Technical Field

[0001] This invention relates to train signal control systems, and more particularly to a method, equipment, and medium for switching the virtual train formation wireless block center in heavy-haul railways. Background Technology

[0002] Virtual train formation uses wireless communication and automatic control technologies to share information and coordinate control between two or more adjacent trains, forming a logical community to complete train control and scheduling. It breaks through the constraint of the existing block system that assumes the preceding train is stationary, significantly reduces the tracking distance between trains, shortens the running interval, and has the advantage of adapting to the uneven spatial and temporal distribution of freight.

[0003] The Virtual Train Radio Block Center (V-RBC) is a key piece of equipment for controlling the operation of train formations. By controlling each train in a virtual train formation to follow its preceding train closely, it enables the stable and coordinated operation of the virtual train formations, ultimately achieving the goal of safe and efficient operation of the train group.

[0004] When a heavy-haul line has a large number of stations under its jurisdiction, multiple radio block centers are needed for segmented management. Therefore, ensuring train throughput efficiency and enabling virtual train formations to pass at high speeds becomes a technical problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a method, equipment and medium for switching virtual train formation wireless block centers in heavy-haul railways, thereby ensuring that train formation and non-train formation can efficiently exchange rights, shorten train intervals and improve the line's transport capacity.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to a first aspect of the present invention, a method for switching virtual marshalling radio block centers (V-RBCs) on heavy-haul railways is provided. This method designs two switching modes for non-marshalling trains and marshalling trains: a V-RBC-dominated right-of-way and a vehicle-dominated right-of-way. The switching method includes:

[0008] 1) The process of transferring the monitoring rights of non-formation trains from one V-RBC to the adjacent V-RBC under the V-RBC dominant handover mode;

[0009] 2) The process of transferring the monitoring rights of a non-formation train from one V-RBC to an adjacent V-RBC under the onboard dominant handover mode;

[0010] 3) The process of transferring the monitoring rights of non-formation trains from one V-RBC to the adjacent V-RBC in the V-RBC dominant handover mode for formation trains.

[0011] As a preferred technical solution, this method adopts the V-RBC-dominated handover method in handover intervals with longer handover intervals and better communication quality; and adopts the vehicle-mounted-dominated handover method in handover intervals with shorter handover intervals and unstable communication.

[0012] As a preferred technical solution, the V-RBC-dominated handover mode independently manages train registration and train operation permit calculation, with the handover of V-RBC and receipt of V-RBC as the boundary defined by the execution of the transponder.

[0013] As a preferred technical solution, the onboard-led right-of-way mode allows the train to establish communication with both V-RBCs and manage train formations and authorizations independently.

[0014] As a preferred technical solution, the process of transferring the monitoring rights of non-formation trains from one V-RBC to an adjacent V-RBC in the V-RBC-dominated handover mode specifically includes:

[0015] Step S101: When the train's operation permission extends to the jurisdiction of the receiving V-RBC, the handover V-RBC integrates the information within the jurisdiction of the receiving V-RBC into the train's operation permission and sends it to the train.

[0016] Step S102: When the handover V-RBC determines that the train's reported location is at the pre-announcement transponder location, and the train's travel permission has crossed the handover boundary, send the distance and IP address for receiving the V-RBC to the train.

[0017] Step S103: Establish communication with the receiving V-RBC. The train registers with the receiving V-RBC and sends parameter information.

[0018] Step S104: The train enters the receiving V-RBC, the train's maximum safe front end moves out to hand over the V-RBC, the handing-over V-RBC sends a notification message to the receiving V-RBC, and the receiving V-RBC sends a takeover message to the handing-over V-RBC.

[0019] Step S105: End the session with the previous V-RBC. After the train's minimum safe rear end leaves the handover V-RBC, end the communication session with the handover V-RBC.

[0020] As a preferred technical solution, the information received in step S101 within the jurisdiction of the V-RBC includes route conditions, line conditions, and temporary speed limits.

[0021] As a preferred technical solution, the process of transferring the monitoring right of a non-formation train from one V-RBC to an adjacent V-RBC in the onboard dominant handover mode specifically includes:

[0022] Step S201: Establish communication with the receiving V-RBC. After the fully monitored train enters the shared management section, it establishes communication with the receiving V-RBC.

[0023] Step S202: Train operation permission extended to the receiving party. The transferring party V-RBC integrates the section train information, hidden car information and formation information sent by the receiving party V-RBC to calculate the train operation permission extended to the receiving party for the transferring party train. The train reaches the farthest forward entry signal to establish communication with the receiving V-RBC. After the fully monitored train enters the co-managed section, it establishes communication with the receiving party V-RBC.

[0024] Step S203: The receiving V-RBC takes over. After the train enters the receiving station, the V-RBC is handed over to stop calculating the train operation permission. The receiving station calculates it independently and extends beyond the previous station entry signal.

[0025] Step S204: Disconnect V-RBC communication. After the train enters the receiving station, in order to facilitate the transferring party to calculate the train operation permission for subsequent trains, communication with the transferring party will not be disconnected temporarily. Communication with the transferring party will be disconnected after the train enters the station.

[0026] As a preferred technical solution, the process of transferring the monitoring rights of non-formation trains from one V-RBC to an adjacent V-RBC in the V-RBC-dominated handover mode of the formation train is as follows:

[0027] Step S301: When the train's travel permit reaches the V-RBC switching boundary, the handover V-RBC sends a train handover notice to the receiving V-RBC and requests route information. When the handover V-RBC obtains the route information provided by the receiving V-RBC, it sends a train travel permit extending into the receiving V-RBC area to the train.

[0028] Step S2: When the train is running close to the V-RBC switching boundary, the V-RBC is handed over to send a V-RBC switching command to the virtual train. If the onboard communication radio is normal, a communication connection is established with the receiving V-RBC.

[0029] Step S3: After the maximum safe leading edge of the last car of the train passes the V-RBC switching point, the receiving V-RBC sends the train takeover information to the handover V-RBC. If the virtual train is connected normally with both the handover V-RBC and the receiving V-RBC, then only the train operation permission information of the receiving V-RBC should be used.

[0030] Step S4: When the minimum safe rear end of the last car of the train passes the V-RBC switching transponder group, the on-board equipment terminates the communication connection with the handover V-RBC. If the on-board equipment was only connected to the handover V-RBC before the handover, the on-board equipment should restart the connection to receive the V-RBC and complete the train registration and apply for the driving permit.

[0031] According to a second aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0032] According to a third aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] 1) This invention proposes a flexible train formation that can adapt to different train types, improving operational efficiency and operational flexibility. It ensures efficient right-of-way transfer between formed and unformed trains, shortens headway, and increases line transport capacity.

[0035] 2) In the application of virtual train formation technology on heavy-haul railways, this invention designs two modes for handover: V-RBC-led and train-led, for non-formation trains and formation trains respectively. This not only satisfies the handover of formation trains but also accommodates the switching of control over non-formation trains, allowing selection based on the specific project requirements. For example, in sections with longer handover distances and better communication quality, the V-RBC-led handover mode can be used; in sections with shorter handover distances and unstable communication, the onboard-led handover mode can be used.

[0036] 3) The V-RBC dominant handover method of this invention has a clear spatial boundary between the handover and receipt of V-RBCs and has a well-defined interaction process. The handover and receipt of V-RBCs are separated by the transponder, and each manages the registration and operation permission calculation of the train independently, with less cross-interference. Moreover, this method can adapt to the handover process of single-radio trains.

[0037] 4) The onboard-led handover method of this invention establishes communication between the train and both V-RBCs, managing train formation and authorization independently without the need for splicing authorization. When communication between the departing train fails and is restored, the handover process can be resumed simultaneously, ensuring train handover efficiency. Furthermore, the information exchange between V-RBCs is relatively simple, greatly reducing the probability of errors. Moreover, there is little difference between non-formation and formation trains, making it more adaptable. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0043] This invention designs two handover modes for non-formation trains and formation trains respectively: V-RBC-led right-of-way and train-led right-of-way. This addresses the issue that V-RBC needs to accommodate both the handover of formation trains and the switching of control over non-formation trains. A comparison of the two methods reveals their advantages and disadvantages, allowing for adaptation to different scenarios.

[0044] This invention requires no additional equipment and can be implemented using software algorithms, thus reducing equipment investment and lowering system costs.

[0045] The method of the present invention includes:

[0046] 1) The process of transferring the monitoring rights of non-formation trains from one V-RBC to the adjacent V-RBC under the V-RBC dominant handover mode;

[0047] 2) The process of transferring the monitoring rights of a non-formation train from one V-RBC to an adjacent V-RBC under the onboard dominant handover mode;

[0048] 3) The process of transferring the monitoring rights of non-formation trains from one V-RBC to the adjacent V-RBC in the V-RBC dominant handover mode for formation trains.

[0049] In the non-formation train V-RBC dominant handover mode, the transfer of non-formation train monitoring rights from one V-RBC to an adjacent V-RBC requires the following steps.

[0050] In step S101, when the train's travel permit extends to the jurisdiction of the receiving V-RBC, the transferring V-RBC integrates information such as route conditions, line conditions, and temporary speed limits within the jurisdiction of the receiving V-RBC into the train's travel permit and sends it to the train.

[0051] Step S102: When the handover V-RBC determines that the train's reported location is at the pre-announcement transponder location, and the train's travel permission has crossed the handover boundary, the distance and IP address for receiving the V-RBC are sent to the train.

[0052] Step S103: Establish communication with the receiving V-RBC. The train registers with the receiving V-RBC and sends parameter information.

[0053] Step S104: Train enters to receive V-RBC. The train's maximum safe leading edge moves out to hand over V-RBC (enters to receive V-RBC). The handing-over V-RBC sends a notification message to the receiving V-RBC, and the receiving V-RBC sends a takeover message to the handing-over V-RBC.

[0054] Step S105: End the session with the previous V-RBC. After the train's minimum safe rear end departs and the V-RBC is handed over, the communication session with the handed-over V-RBC is ended.

[0055] In the onboard dominance handover mode for both formation and non-formation trains, the transfer of monitoring rights for a non-formation train from one V-RBC to an adjacent V-RBC requires the following steps.

[0056] Step S201: Establish communication with the receiving V-RBC. After the fully monitored train enters the shared section, it establishes communication with the receiving V-RBC.

[0057] Step S202: Train permission extended to the receiving end. The transferring V-RBC integrates the section train information, hidden car information, and formation information sent by the receiving V-RBC to calculate the train permission extension to the receiving end for the transferring train, reaching as far as the next station entrance signal to establish communication with the receiving V-RBC. After the fully monitored train enters the shared section, it establishes communication with the receiving V-RBC.

[0058] Step S203: The receiving V-RBC takes over. After the train enters the receiving station, the handover of the V-RBC can stop calculating train clearances for it, which will then be calculated independently by the receiving station, and can extend beyond the preceding station entry signal.

[0059] Step S204: Disconnect V-RBC communication. After the train enters the receiving station, communication with the receiving station will be temporarily disconnected to facilitate the receiving station's calculation of train operation permits for subsequent trains. Communication with the receiving station will be disconnected after the train enters the station.

[0060] In the V-RBC-dominated handover mode for train formations, the transfer of monitoring rights for non-formation trains from one V-RBC to an adjacent V-RBC requires the following steps.

[0061] Step S301: When the train's travel permit reaches the V-RBC switching boundary, the handover V-RBC sends a train handover notice to the receiving V-RBC and requests route information. When the handover V-RBC receives the route information provided by the receiving V-RBC, it sends a travel permit extending into the receiving V-RBC area to the train.

[0062] Step S302: When the train formation approaches the V-RBC switching boundary, the V-RBC is handed over to send a V-RBC switching command to the virtual train formation. If the onboard communication radio is working properly, a communication connection is established with the receiving V-RBC.

[0063] Step S303: After the maximum safe leading edge of the last car of the train passes the V-RBC switching point, the receiving V-RBC sends train takeover information to the handover V-RBC. If the virtual train is properly connected to both the handover V-RBC and the receiving V-RBC, then only the train operation permission information from the receiving V-RBC should be used.

[0064] Step S304: When the minimum safe rear end of the last car of the train passes the V-RBC handover transponder group, the onboard equipment terminates the communication connection with the handover V-RBC. If the onboard equipment was only connected to the handover V-RBC before the handover, the onboard equipment should restart the connection to receive the V-RBC and complete the train registration and apply for the operating permit. Specific Implementation

[0066] This invention implements virtual train formation technology on heavy-haul railways. For the right-of-way process of virtual train formation and non-virtual train formation, it designs two modes: V-RBC-led right-of-way and train-led right-of-way, respectively, to adapt to the needs of different scenarios.

[0067] I. For non-formation trains, V-RBC takes the lead in handing over control, such as... Figure 1 As shown.

[0068] Train A is in the V-RBC jurisdiction area being transferred, and Train A's travel permit extends to the jurisdiction of the receiving V-RBC. The transfer process is activated, and the transferring V-RBC integrates information such as route conditions, track conditions, and temporary speed limits within the jurisdiction of the receiving V-RBC into the travel permit of the transferring train and sends it to Train A.

[0069] When the handover V-RBC determines that the location reported by train A is at the position of the advance transponder, and the train A's travel permission has passed the handover execution transponder, the handover V-RBC sends the distance and IP address of the receiving V-RBC to train A.

[0070] Train A registers with the receiving V-RBC and establishes communication with it.

[0071] Train A's maximum safety front end moves out of the handover V-RBC (moves into the receiving V-RBC), the handover V-RBC sends a notification message to the receiving V-RBC, and the receiving V-RBC sends a takeover message to the handover V-RBC.

[0072] After the minimum safe rear end of train A departs from the handover V-RBC, the communication session with the handover V-RBC ends.

[0073] II. Onboard control of non-formation trains, such as Figure 2 As shown.

[0074] After fully monitored train A enters the shared area for handing over and receiving V-RBCs, it establishes communication with the receiving V-RBC.

[0075] The transferring V-RBC integrates the section train information, hidden car information, and formation information sent by the receiving V-RBC to calculate the train operation permission for the transferring train A, extending to the receiving end and reaching as far as the next station entrance signal.

[0076] After train A enters the receiving V-RBC, the handover V-RBC can stop calculating train clearance for it, and the receiving V-RBC will calculate it independently, and it can extend beyond the previous station entry signal.

[0077] After train A enters the receiving party's V-RBC, communication with the receiving party will be temporarily suspended to facilitate the transferring party in calculating the train operation permission for subsequent train A. Communication with the transferring party will be suspended again after train A enters the station.

[0078] III. The V-RBC (Vehicle-to-Train Controller) takes the lead in handing over the command of the Figure 3 As shown.

[0079] When the travel permit endpoint of train A reaches the V-RBC handover boundary, the handover V-RBC sends a train handover notice to the receiving V-RBC and requests route information. Once the handover V-RBC receives the route information provided by the receiving V-RBC, it sends a travel permit to train A extending into the area of ​​the receiving V-RBC.

[0080] When train A approaches the V-RBC switching boundary, the V-RBC handover sends a V-RBC switching command to the virtual train. If the onboard communication radio is functioning properly, a communication connection is established with the receiving V-RBC.

[0081] Once the maximum safe leading edge of the last car of train A crosses the V-RBC switching point, the receiving V-RBC sends train takeover information to the handover V-RBC. If the virtual train is properly connected to both the handover V-RBC and the receiving V-RBC, then only the train operation permission information from the receiving V-RBC should be used.

[0082] When the minimum safe rear end of the last car of train A passes the V-RBC handover transponder group, the onboard equipment terminates the communication connection with the handover V-RBC. If the onboard equipment was only connected to the handover V-RBC before the handover, the onboard equipment should restart the connection to receive the V-RBC and complete train registration and apply for operating permission.

[0083] IV. Onboard-dominated handover methods in train marshalling, such as Figure 4 As shown.

[0084] After train A enters the shared management area, it calls the receiving V-RBC and establishes communication. The V-RBC exchanges train information and hidden car information within its jurisdiction, and simultaneously calculates the train operation permit for train A and sends it to the onboard equipment, which selects whether to use it based on the train's position. Within the shared management area, the train operation permit from the transferring party only extends to the next station entry signal.

[0085] When the minimum safe rear end of train A passes the V-RBC switching transponder group, the handing party will no longer send a train travel permit. The receiving V-RBC can extend the travel permit based on the road conditions ahead.
