DETAILED DESCRIPTION OF THE EMBODIMENTS

[0056] The present invention is further described in detail below with reference to the drawings and specific embodiments. The advantages and features of the present invention are clearer according to description and claims below. It should be noted that the drawings in a very simplified form and with an imprecise scale are only used to conveniently and clearly assist in describing the embodiments of the present invention.

[0057] To solve the technical problems in the background, the present invention provides a method capable of implementing resource sharing in common line areas, saving costs, and improving the efficiency of train operation, that is, a method for interconnection and intercommunication between a virtual marshalling train control system and an existing line train control system in a heavy haul railway. According to the present invention, on the basis of compatibility with existing signal systems in the heavy haul railway, in order to ensure the interconnection and intercommunication between operating lines using virtual marshalling and existing lines, the switching between ground equipment in different signal systems and between ground equipment and on-board equipment can be completed by designing switching areas and switching times of the systems, and based on marshalling plans and marshalling commands issued by a dispatch center, such that the switching between the different signal systems can be dynamically implemented.

[0058] The interconnection and intercommunication method and system for a virtual marshalling train control system in a heavy haul railway in this embodiment are described below with reference to the drawings.

[0059] FIG. 1 is a flowchart of an interconnection and intercommunication method for a virtual marshalling train control system in a heavy haul railway provided by an embodiment of the present invention. As shown in FIG. 1, the method includes steps below.

[0060] In step S1, a switching area for switching ground equipment between an existing line and a virtual marshalling line is determined.

[0061] The step of determining a switching area for switching ground equipment between an existing line and a virtual marshalling line includes: [0062] arranging a ground equipment switching balise group in an overlapped co-management area of the virtual marshalling line and the existing line, and setting an area where the ground equipment switching balise group is located as the switching area for switching the ground equipment.

[0063] Specifically, as shown in FIG. 2, the ground equipment switching balise group can be arranged on an outer side of a station exit in the overlapped co-management area of the virtual marshalling line and the existing line, which serves as a switching area for switching communication between on-board equipment and the ground equipment, where the existing line is a line where an existing line station 1, an interconnection and intercommunication common line station, an existing line station 3, and an existing line station 4 are located, and the virtual marshalling line is a line where the interconnection and intercommunication common line station, a virtual marshalling station 2 and a virtual marshalling station 3 are located.

[0064] In this embodiment, on the premise that the on-board equipment in a virtual marshalling train control system maintains communication with the ground equipment in an existing line train control system, a train pulls out of a station in a train operation mode of the existing line train control system, and then the handover and switching between the on-board equipment and the existing ground equipment or the ground equipment in the virtual marshalling line is completed in the switching area.

[0065] The virtual marshalling train control system includes the on-board equipment and the ground equipment, while the existing line train control system mainly includes the on-board equipment and the corresponding ground equipment. As shown in FIG. 3, the on-board equipment mainly includes an on-board automatic train protection (ATP) host and automatic train operation (ATO) host, a radio communication station, a balise receiving antenna, a Beidou satellite receiver, a speed sensor, a driver machine interface (DMI), an end of train (EOT), etc. The ground equipment in the existing line train control system mainly includes a centralized traffic control (CTC) system in the existing system, a CTC station extension in the existing system, interlocking equipment in the existing system, and a radio block center in the existing system. The ground equipment in the virtual marshalling train control system includes virtual marshalling CTC equipment, a virtual marshalling resource management update (RMU) system, object controller equipment, and a virtual marshalling CTC station extension.

[0066] In step S2, a ground equipment control right is switched when a train runs to within a range of the switching area.

[0067] Specifically, before the train runs to within the range of the switching area, when the train runs to a jurisdictional boundary of an existing management system corresponding to the existing line, radio block center equipment starts to perform interaction on ground equipment switching information with resource management equipment.

[0068] As shown in FIG. 4, when a first train in a train set pulls out of an exit of the interconnection and intercommunication common line station in an existing mode and an end of movement authority of the train reaches the jurisdictional boundary of the existing system, step {circle around (1)} is performed, that is, the radio block center in the existing system starts to perform interaction on the ground equipment switching information with RMU equipment in the virtual marshalling system, namely the above virtual marshalling RMU system.

[0069] Further, when the train runs to within the range of the switching area, the ground equipment control right can be handed over and switched by the on-board equipment of the train.

[0070] In this embodiment, a set of on-board equipment may be used to adapt to the ground equipment in the virtual marshalling line and the ground equipment in the existing line separately. FIG. 5 is a schematic diagram of an interface relationship between existing line equipment and virtual marshalling system equipment provided by an embodiment of the present invention. As shown in FIG. 5, the on-board equipment interacts with the ground equipment in the two systems simultaneously in the switching area, and the ground equipment in the two systems can complete relevant information interaction by the on-board equipment and complete the handover and switching of the ground equipment control right.

[0071] The step of handing over and switching the ground equipment control right by the on-board equipment of the train includes: [0072] when the train runs to the switching area, sending, by radio block center equipment in the existing line, a ground equipment switching command to the on-board equipment of the train; receiving, by the on-board equipment, the ground equipment switching command, sending a communication session establishment request instruction to resource management equipment in the virtual marshalling line, and establishing, by the resource management equipment, a communication session with the on-board equipment after receiving the communication session establishment request instruction; and when the train runs to completely pass through the switching area, performing interaction on ground equipment control right switching information by the established communication session.

[0073] After the ground equipment control right is handed over and switched, the method further includes: terminating, by the on-board equipment, a communication connection with the radio block center equipment, and performing interaction on train operation safety data with the resource management equipment through the communication session, to complete the switching of the ground equipment.

[0074] Specifically, as shown in FIG. 4, when the first train runs to the ground equipment switching balise group, step {circle around (2)} is performed, that is, the radio block center in the existing system sends the ground equipment switching command to the on-board equipment, and then step {circle around (3)} is performed, that is, on-board equipment of the first train calls the RMU equipment in the virtual marshalling system and establishes the communication session, so as to perform interaction on the ground equipment control right switching information through the established communication session. As shown in FIG. 6, when the first train completely passes through the ground equipment switching balise group, step {circle around (4)} is performed, that is, the ground equipment in the two systems performs interaction on the control right switching information. Further, step {circle around (5)} is performed, that is, the on-board equipment of the first train terminates the communication connection with the radio block center in the existing system, maintains the connection with the RMU equipment in the virtual marshalling system, and performs interaction on the train operation safety data, to complete the switching of the ground equipment. After the on-board equipment of the first train completes the switching of the ground equipment, the switching of ground equipment control rights of all trains in the train set and the interaction of the train operation safety data are completed in sequence according to steps {circle around (1)}-{circle around (5)}.

[0075] After the switching of the ground equipment is completed, the method further includes: sending, by the resource management equipment, line resource information; and receiving, by the on-board equipment, the line resource information, and monitoring an operating condition of the train based on the line resource information.

[0076] Specifically, after all the trains in the whole train set pull out of the interconnection and intercommunication common line station in the existing mode, the train set completes the switching of the ground equipment in the switching area, the trains monitor the safe operation thereof based on the line resource information provided by the RMU equipment in the virtual marshalling system, and then the train set runs in a virtual marshalling mode based on a marshalling plan.

[0077] In step S3, after the ground equipment control right is switched, the ground equipment in the virtual marshalling line sends a marshalling command to on-board equipment of the train, and the on-board equipment virtually marshals the train corresponding to the on-board equipment and a train in a formation based on the marshalling command.

[0078] After the switching of the ground equipment is completed, and before the resource management equipment, namely the ground equipment in the virtual marshalling line sends the marshalling command to the on-board equipment, the method further includes: obtaining, by the resource management equipment, a train marshalling plan, checking a train operation line condition based on the train marshalling plan, and sending the marshalling command to the on-board equipment after checking that the train operation line condition meets a train marshalling condition.

[0079] Specifically, as shown in FIG. 7, step 6 can be further performed, that is, the virtual marshalling CTC equipment issues the train marshalling plan to the RMU equipment in the virtual marshalling system, and the RMU equipment in the virtual marshalling system checks the train operation line condition based on the train marshalling plan; and step (7 is performed, that is, the virtual marshalling command is sent to the train set.

[0080] Before the on-board equipment virtually marshals the train corresponding to the on-board equipment and the front train in the formation based on the marshalling command, the method further includes: determining, by the on-board equipment, whether the train meets a marshalling condition based on the marshalling command, and virtually marshalling the train and the front train in the formation when the train meets the marshalling condition. According to the marshalling command, on-board equipment in a first one of a train set to be marshalled runs forward at a maximum speed based on the line condition and the train condition.

[0081] In this embodiment, after all the on-board equipment in the whole train set with the virtual marshalling train control system completes switching of communication with the ground equipment, the first train running in the whole train set can check a virtual formation establishment condition based on the marshalling plan and the marshalling command issued by the ground equipment in the virtual marshalling train control system, and prepares to switch to the virtual marshalling mode.

[0082] In one embodiment of the present invention, the step of virtually marshalling, by the on-board equipment, the train corresponding to the on-board equipment and the front train in the formation based on the marshalling command includes: if the on-board equipment is on-board equipment in a first one of a train set to be marshalled, determining, by the on-board equipment, that the train meets a formation establishment condition, and informing trains in the formation to prepare for marshalling; establishing, by the on-board equipment, train-train communication between the train and the front train in the formation, and performing interaction on train operation information through the train-train communication; and calculating, by the on-board equipment, a relative position-based end of movement authority based on operation information of the train and operation information of the front train, and virtually marshalling the train and the front train in the formation. The on-board equipment completes virtual marshalling of the train and the front train in a manner that a tracking distance between the train and the front train is shortened and reaches a preset value. In this embodiment, the operation information includes speed, acceleration and real-time position information of the train.

[0083] Specifically, as shown in FIG. 7, after the first train running in the train set checks that the marshalling condition is met based on the marshalling command, the trains in the train set can establish the train-train communication connection therebetween and perform interaction on the train operation information, such as the speed, acceleration and real-time position information of the train, through the established train-train communication, and step {circle around (8)} is performed, that is, the train and the front train in the formation are virtually marshalled based on the current operation information of the train and the current operation information of the front train. The specific train can track the front train in the virtual marshalling mode to gradually shorten the tracking distance from the front train. When front and rear trains keep a stable running interval and run in coordination with a virtual formation, dynamic marshalling of interconnection and intercommunication sections can be implemented.

[0084] In this embodiment, the trains in the whole train set perform interaction on the operation information through the train-train communication, and after a mode conversion condition is met, the train set runs in the virtual marshalling mode, such that the train set can dynamically complete the conversion of a virtual marshalling coordinated operation mode in the interconnection and intercommunication sections. It should be noted that the virtual marshalling train control system in this embodiment has a function of cross-line operation from the existing line to the virtual marshalling line, and also has a function of cross-line operation from the virtual marshalling line to the existing line. Thus, the virtual marshalling train control system in this embodiment can complete the switching of the ground equipment under the condition that the train does not stop in a switching section, and complete the virtual marshalling of the train set, thereby implementing the switching between different signal systems, and improving the efficiency of train operation.

[0085] As a specific example, as shown in FIG. 8, the CTC system can send a train plan to the radio block center in the existing system and the virtual marshalling RMU system, namely a resource management center in the virtual marshalling system. When the first train in the train set runs to the ground equipment switching balise group, the radio block center in the existing system and the virtual marshalling RMU system complete the switching of the ground equipment based on the train plan and by the on-board equipment; after completing the switching of the ground equipment, the on-board equipment terminates the communication with the ground equipment in the existing train control system; the ground equipment in the virtual marshalling train control system issues the marshalling command to on-board equipment CC1 and on-board equipment CC2 in the whole train set in a timely manner based on the marshalling plan issued by the CTC system; and the on-board equipment CC1 and the on-board equipment CC2 establish the communication between the trains based on the marshalling command and complete dynamic marshalling.

As shown in FIG. 9, the interconnection and intercommunication system 10 for a virtual marshalling train control system in a heavy haul railway includes a determination module 11, a switching module 12, and a marshalling module 13.

[0087] Specifically, an overlapped co-management area of the virtual marshalling line and the existing line can be first determined by the determination module 11, and a ground equipment switching balise group is arranged in the overlapped co-management area, to determine the switching area for switching the ground equipment between the existing line and the virtual marshalling line. When a train in a train set runs to the switching area, the determination module 11 sends out a determination instruction that the train runs to the switching area. After receiving the determination instruction, the switching module 12 confirms that the train runs to the switching area, then switches the ground equipment control right by the on-board equipment, and sends out a ground equipment switching completion instruction. After receiving the ground equipment switching completion instruction, the marshalling module 13 confirms that the switching of the ground equipment control right is completed, receives a marshalling command sent by a virtual marshalling RMU system based on a marshalling plan issued by virtual marshalling CTC equipment, and then performs virtual marshalling on the corresponding train and the front train in the formation based on the marshalling command, such that the train set can dynamically complete the conversion of a virtual marshalling coordinated operation mode in interconnection and intercommunication sections.

[0091] In summary, according to the present invention, on the basis of compatibility with existing signal systems in the heavy haul railway, in order to ensure the interconnection and intercommunication between operating lines using virtual marshalling and existing lines, the switching between ground equipment in different signal systems and between ground equipment and on-board equipment can be completed by designing switching areas and switching times of the systems, and based on marshalling plans and marshalling commands issued by a dispatch center, such that the switching between the different signal systems can be dynamically implemented, the transport capacity of a freight railway in cross-line operation can be improved, the train set can run in a virtual marshalling mode of shortening the operating distance between the trains, and the overall operation efficiency of a train operation system can be improved; moreover, according to the present invention, after the virtual marshalling train control system is used in the heavy haul railway, the interconnection and intercommunication with the existing train control system can be implemented by sharing common line ground equipment resources and existing train on-board equipment, such that the construction and operation costs of the train operation system can be effectively reduced on the whole; and according to the present invention, the interconnection and intercommunication between the virtual marshalling train control system and the existing line train control system can be implemented without stop, seamless switching between the virtual marshalling train control system and the existing train control system can be implemented, the availability of the virtual marshalling train control system can be enhanced, and the popularization and application of the virtual marshalling train control system are facilitated.
