Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
The following describes a train turning back method and system according to an embodiment of the invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method of turning back a train according to an embodiment of the present invention. As shown in fig. 1, a method for turning back a train according to an embodiment of the present invention includes:
s101: an automatic train control system (ATS) receives train configuration information transmitted from a vehicle controller (VOBC) of a train.
Generally, the train set information includes 4 set information and 8 set information, wherein 4 set information refers to a train in which 4 cars are combined together, and 8 set information refers to a train in which 8 cars are combined together.
S102: the automatic train control system selects a first link area or a combined area formed by combining the first link area and a second link area adjacent to the first link area as a retrace area according to train formation information, and feeds back a retrace area ID to the on-board controller.
In an embodiment of the present invention, if the train configuration information is 4, the automatic train control system selects the first link area as a turnaround area of the train, and sends a turnaround area ID corresponding to the first link area to the on-board controller; if the train configuration information is 8 formation information, the automatic train control system selects a combination area formed by combining the first link area and a second link area adjacent to the first link area as a retrace area of the train, and sends a retrace area ID corresponding to the combination area to the on-board controller.
That is, in the information transmitted from the VOBC to the ATS, train consist information is included; in the electronic map stored in the ATS, a record of the electronic map is added, in which a fold-back link a (i.e., a first link area) and an adjacent link B (i.e., a second link area) are combined into a link ab (i.e., a combined area). In this way, the ATS can determine to select link a as a turnaround area or link ab as a turnaround area according to train consist information, and the turnaround area corresponds to a turnaround area ID used by the ATS. Further, the ATS may transmit a corresponding foldback area ID to the VOBC.
S103: and the vehicle-mounted controller controls the train to turn back according to the turn-back area ID.
For example: and the vehicle-mounted controller obtains an index number according to the ID of the turn-back area. And obtaining a link area number according to the index number, and turning back at a position corresponding to the link area number.
In the above example, obtaining a link region number from an index number, and performing foldback at a position corresponding to the link region number includes: if the index numbers are two, the link area numbers correspond to the combined area; and if the index numbers are 1, the number of the link area corresponds to the first link area.
Accordingly, the switch-back can be automatically performed in the case of a short train set (i.e., 4 train set), and similarly, the switch-back can be smoothly and automatically performed in the case of a long train set (i.e., 8 train set).
The method of the embodiment of the invention can solve the problem that 8 marshalling trains can not be turned back smoothly, such as: some train lines, due to initial civil engineering problems, the turnaround area includes switches, resulting in the turnaround track containing multiple links. Currently, the ATS cannot determine whether a train is stationary or not and cannot perform a good turning back determination for such a problem. The reason is that the parking area only comprises one axle counting section, one parking area only comprises one link, and when the train occupies more than one link, the ATS considers that the train does not completely enter the parking area, so that the stability of the train cannot be judged, and the turn-back command cannot be sent to the train.
By the method of the embodiment of the invention, 8 marshalling trains can be turned back by occupying turnouts outside the pressure turn-back area when the train is in the turn-back area with limited length. Specifically, when pressing a switch, an 8-marshalling train occupies two links, because the conventional VOBC does not support a mode that one parking area corresponds to a plurality of links, the two links need to correspond to two parking areas, but the ATS also requires that the two links in one axle counting section correspond to one parking area, otherwise, the ATS cannot process the two links, and in order to realize switch pressing return, a data structure corresponding to the 8-marshalling train is included. Namely: a record of the electronic map combined into linkabs is added. As shown in fig. 2, the first column of parking area numbers VOBC are dedicated to different parking areas according to different links required by VOBC. The last row of ATS parking area IDs is newly added, and the number of the parking areas corresponding to different links of one axle counting section is the same, and the parking areas corresponding to two vehicles are the same, for example, the number of the parking area ID for the ATS is 46, and the number of the parking area ID corresponding to two vehicles (i.e., index number) is 5 and 46. Thus, the axle counting section composed of two links can be determined, and the turn-back position can be known.
As shown in fig. 3: when the train turns back at the 1DG switch, the parking area number transmitted by the ATS to the VOBC is the last-column ATS parking area ID46, that is: in the ATS parking area ID in fig. 2, the VOBC receives the parking area number sent by the ATS, finds the parking areas of the first column index numbers 46 and 5 used by the VOBC according to the number, and performs the parking return work according to the position. As can be seen from the figure, VOBC should automatically fold back at the switch location sections of the corresponding link30 and link 27.
When the train is composed of 4 trains, the retracing area is as shown in fig. 4, the retracing rail 1G includes a link30, and the train completely enters the axle counting section 1G and is retraced when being retraced.
According to the method for turning back the train, when the 4-marshalling train or the 8-marshalling train is adopted in the train, the train can be correctly turned back, so that the flexibility and the reliability of the turning back of the train are improved.
Fig. 5 is a block diagram of a structure of a return system of a train according to an embodiment of the present invention. As shown in fig. 5, the folding back system of a train according to one embodiment of the present invention includes: an automatic train control system 510 and an onboard controller 520.
The automatic train control system 510 receives train formation information sent by an on-board controller 520 of a train; the train automatic control system 510 selects a first link area or a combined area formed by combining the first link area and a second link area adjacent to the first link area as a retrace area according to the train formation information, and feeds back a retrace area ID to the on-board controller 520; the on-board controller 520 controls the train to turn back according to the turn-back area ID.
