At present, the logic tracking of train number by the CTC system is performed based on the state of the track circuit collected in real time.

[0003] At present, the state of logic tracking of the train number in the section by the CTC system is as follows: only the logical tracking of a single train driving into the same block section is supported. A moving block mode based on the novel train control system allows multiple trains to drive into the same block section. In such a scenario, when multiple trains drive into the same block section, the CTC system cannot logically track the train number.

[0004] A single block section is only associated with single train window equipment, and multiple trains driving into the same block section cannot be displayed.

[0005] At present, the train number is logically tracked by only using a real-time state of track circuit. When the train drives into the occupied block section, it is impossible to logically track the train number of the train that drives into the block section later.

[0006] Therefore, how to logically track the trains of a train control system that supports multiple trains to drive into a unified block section has become an urgent technical problem.SUMMARY

[0010] Further, the tracking train numbers of multiple trains in each block section includes the following steps: providing one piece of main train number window equipment and N pieces of additional train number window equipment associated with each other for each piece of block section equipment, where N is greater than or equal to 0; and associating each piece of additional train number equipment with the corresponding main train number window equipment.

[0012] Further, the method includes the following steps: determining the current block section to which the train belongs according to the train position information, and logically tracking a train number section under the novel train control system by combining state information of a track circuit.

[0013] Further, the method includes the following steps: if a track circuit of the current block section is in an unoccupied state, not allowing to track the train number to the current block section.

[0016] Further, when the train number is logically tracked to train number window equipment associated with the block section equipment, the train number window equipment is selected according to the following steps: allowing to logically track the train number to the block section only when associated train number window equipment without train number exists in the block section; preferably moving to the train to the main train number window equipment associated with the block section equipment; and when a train already exists in the main train number window equipment, searching to first additional train number window equipment without the train according to a sequence of the serial numbers of the additional train number window equipment, and logically tracking the train number to the additional train number window equipment.

[0017] Further, when the train number in the main train number window equipment or additional train number window equipment is removed, the train numbers in the subsequent train number window equipment are sequentially updated to the previous train number window equipment. the present disclosure provides a system for tracking a train number in a section, including a position determining unit, configured to acquire train position information provided by a novel train control system; and a train number window tracking unit, configured to track train numbers of a plurality of trains in each block section based on the train position information.

[0031] To describe the technical solutions of the present disclosure or in the prior art more clearly, the following briefly introduces the accompanying drawings required for describing the embodiments or the prior art. Apparently, the accompanying drawings in the following description show merely some embodiments of the present disclosure, and those of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts. FIG. 1 shows a flow diagram of a method for tracking a train number in a section according to an embodiment of the present disclosure; FIG. 2 shows a flow diagram of a method for tracking a train number in a section according to an embodiment of the present disclosure by combining state information of a track circuit; FIG. 3 shows a structural diagram of a system for tracking a train number in a section according to an embodiment of the present disclosure. DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions and advantages of the present disclosure more clearly, the following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0033] An embodiment of the present disclosure provides a method for tracking a train number in a section, in particular a method for tracking a train number in a section based on a novel train control system. The novel train control system is a train control system that supports multiple trains to drive into a same block section (block section for short). As shown in FIG. 1, a flow diagram of a method for tracking a train number in a section includes the follows: Train position information provided by the novel train control system is acquired, and train numbers of multiple trains in each block section are tracked based on the train position information. Specifically, the train position information provided by the novel train control system is applied to a CTC system, and the CTC system is configured to track the train numbers of multiple trains in each block section. Further, the train position information is combined with state information of a track circuit collected in real time for two-dimensional traceability, thus achieving section logic tracking under the novel train control system.

[0034] The tracking the train numbers of multiple trains in each block section is as follows: each block section equipment is provided with one piece of main train number window equipment (main train number window for short) and N pieces of additional train number window equipment (additional train number window for short) associated with each other, where N is greater than or equal to 0. The additional train number window equipment of each block section equipment is associated with the main train number window equipment. That is, the main train number window is directly associated with the block section where the train is located, and the additional train number window is subordinate to the main train number window. Only when there is a train in the main train number window associated with the block section, the following train can enter the additional train number window. Only the train on the main train number window can be moved to an adjacent block section. A single block section allows only the main train number window equipment to be provided. Only after the main train number window equipment is provided, the additional train number window equipment can be provided for the single block section.

[0035] The main train window and the additional train windows provided for the block section equipment are sequenced and numbered. Serial numbers of the main train number window equipment and the additional train number window equipment are continuous, and the serial number of the main train number window equipment is set as a starting point of the serial numbers. The additional train number windows are sequenced in turn from near to far according to a distance from the block section equipment in a station-yard map. Exemplary, the serial numbers of the train number windows employ an arithmetic sequence, the serial number of the main train window number is the smallest, and the serial numbers of the additional train windows increase in turn according to the natural number. For example, the serial number of the main train number window is 0. The additional train number windows are numbered in turn from near to far according to the distance from the block section equipment in the station-yard map, which are numbered as 1, 2, ...N in turn. When the train numbers are logically tracked, the trains enter the train number window equipment in turn based on the serial numbers of the train number windows according to the time of driving into the block section, for example, the trains enter the train number window equipment with the serial numbers of 0, 1, ...N.

[0036] The following is an exemplary description of the process of tracking multiple trains in the block section by the CTC.

[0037] As shown in FIG. 2, a train number tracking program can accurately locate a block section A (i.e., a current block section) to which the train currently belongs according to the train position information of the train (a target train). Specifically, the train position information acquired by the CTC system includes information of corresponding (located) first district equipment of the train in a train control center, information of corresponding second district equipment in the CTC system is acquired according to the information of the first district equipment, and the current block section where the train is located is determined according to the information of the second district equipment.

[0038] Exemplary, the train control center transmits a serial number of train control equipment (the first district equipment) to the CTC system at a position where the train is located, and the CTC system finds out the corresponding district equipment of the CTC system through a mapping relationship of serial numbers of the internal equipment, and then determines the current block section to which the train belongs. The train number window associated with the current block section is acquired for logically tracking the train number. In this way, the train position information is converted into the train number in the CTC system for operation dispatching command by the CTC system.

[0039] The acquired information of the current block section is dynamically combined with a real-time state of the track circuit of the current block section A, and the train number is logically tracked to the block section A, which is specifically as follows: when a track circuit of the block section A is in an unoccupied state, it is not allowed to logically track the train number to the block section A. That is, when the track circuit is unoccupied but the train position information transmitted by the train control system indicates that the train has entered the block section, this situation is abnormal, and thus it is not allowed to logically track the train number to the block section A. The logical tracking of the train number can be carried out when the state of the track circuit is consistent with the train control state.

[0040] When there is the same train number as the train in the main train number window or additional train number window associated with the current block section A, the train number is no longer repeatedly tracked to the block section A, and only RBC (radio block center) related attributes of the train are updated.

[0041] When there is a train with the same train number in the main train number window associated with an adjacent block section B of the current block section A, and a movement direction of the train moved from the block section B to the block section A (depending on a direction attribute configured in static configuration data of the CTC system) is consistent with an actual movement direction of the train (depending on a direction attribute generated when the CTC system logically tracks the train number), the train number is logically tracked to the block section A.

[0042] When the train number is logically tracked to the train number window equipment associated with the block section equipment, the train number window is selected according to the following steps: only when there is associated train number window equipment without a train number (i.e., idle train number window equipment) in the block section, the train number is allowed to be logically tracked to the block section; the train is preferably moved to the main train number window equipment associated with the block section equipment; and when there is a train in the main train number window, a first additional train window without a train is searched according to the sequence of the serial numbers of the additional train number windows, and the train number is logically tracked to the additional train number window. Specifically, the search starts from the additional train number window with the serial number close to that of the main train number window. In the embodiment of the present disclosure, the serial numbers of the main train number window and the related additional train number windows form an ascending arithmetic progression, so the idle additional train number windows are searched in the sequence from small to large.

[0043] When the train number in the main train number window equipment or additional train number window equipment is removed, the train numbers in the subsequent train number window equipment are sequentially updated to the previous train number window equipment. Exemplary, as shown in the following table, when the train in the main train number window is removed due to logic tracking, if there are trains in the additional train number windows associated with the block section, the trains in the additional train windows with the serial number of 1, 2, ... and N need to be moved into the main train number window and the additional train windows with the serial number of 1, ... and N-1 in sequence.

[0044] When the train in the additional train number window with the serial number of x is removed by manual operation, and there are trains in the following additional train number windows with the serial numbers of x+1...N associated with the block section, the trains in the additional train number windows with the train need to be sequentially moved into the additional train number windows with the serial numbers of x, ...N-1. Train number window01...x...N-1NTrain number before removing1234567Train number after removing123567Train number after moving123567

[0045] Based on the same inventive concept, an embodiment of the present disclosure provides a system for tracking a train number in a section. As shown in FIG. 3, the system includes a position determining unit, configured to acquire train position information provided by a novel train control system; and a train number window tracking unit, configured to track train numbers of multiple trains in each block section based on the train position information. The novel train control system is a train control system that supports the multiple trains to drive into the same block section.

[0046] Further, the position determining unit is configured to determine information of corresponding first district equipment of a train in a train control center in the train position information, acquire information of corresponding second district equipment in the system according to the information of the first district equipment, and determine a current block section where the train is located according to the information of the second district equipment.

[0047] The system further includes a train number window management unit, configured to: provide each block section equipment with one piece of main train number window equipment and N pieces of additional train number windows associated with each block section equipment, where N is greater than or equal to 0; and associate each piece of additional train number equipment with the corresponding main train number window equipment.

[0048] The train number window management unit is configured to sequence and number a main train window and additional train windows provided on the block section equipment, wherein serial numbers of the main train number window equipment and the additional train number window equipment are continuous, and the serial number of the main train window is set as a starting point of the serial numbers; number the additional train number window equipment in turn from near to far according to a distance from the block section equipment in a station-yard map.

[0049] When the train number is logically tracked, the train number window tracking unit enters the train number window equipment in turn according to the time of driving into the block section and the serial numbers of the train number windows.

[0050] The train number window tracking unit is further configured to determine the current block section to which the train belongs according to the train position information, and logically track a train number section under the novel train control system by combining state information of a track circuit. If a train with the same train number already exists in the main train number window equipment of an adjacent block section of the current block section, and a movement direction of the train moved from the adjacent block section to the current block section is consistent with an actual movement direction of the train, the train number can be logically tracked to the current block section.

[0051] The logic tracking of a train number window of a system for tracking a train number in a section according to an embodiment of the present disclosure can be achieved according to the method for tracking a train number in a section according to an embodiment of the present disclosure, and thus will not be described in detail. Without losing generality, the system for tracking a train number in a section according to an embodiment of the present disclosure can be implemented as a centralized train control system.

[0052] The method and system for tracking a train number in a section provided by the embodiment of the present disclosure can solve the problem that a CTC system cannot logically track the train number when multiple trains drive into the same block section under the novel train control system. The train position is determined by combining various information, and the positioning is accurate. Multiple pieces of train number window equipment are used for associated display, which is convenient for clearly determining the current positions and frontback relationship of the multiple trains.

[0053] Although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the foregoing embodiments, or to replace partial technical features with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of various embodiments of the present disclosure.
