The present invention relates to the technical field of railway transportation, in particular to an interconnection and intercommunication method and system for a virtual marshalling train control system in a heavy haul railway, a storage medium, and an electronic device.

On the basis of maximizing the utilization of existing infrastructures, the constraint of a current signal block system regarding a front train as static is broken. On the premise of safety, two or more adjacent trains are virtually marshalled to form a “whole train set” to complete train operation control and transport organization, which can significantly shorten the safety protection distance between the trains in the train set, and reduce the tracking interval of the trains, thus improving the transport capacity of lines.

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.
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.
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.
In step S1, a switching area for switching ground equipment between an existing line and a virtual marshalling line is determined.
The step of determining a switching area for switching ground equipment between an existing line and a virtual marshalling line includes:
Specifically, as shown in
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.
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
In step S2, a ground equipment control right is switched when a train runs to within a range of the switching area.
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.
As shown in
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.
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.
The step of handing over and switching the ground equipment control right by the on-board equipment of the train includes:
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.
Specifically, as shown in
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.
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.
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.
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.
Specifically, as shown in
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.
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.
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.
Specifically, as shown in
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.
As a specific example, as shown in
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.
