[0039] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0040] PIS (Passenger Information System) is a system that provides information services to passengers based on multimedia network technology, with computer systems as the core and station and on-board display terminals as the medium. Under normal circumstances, the passenger information system provides real-time dynamic multimedia information such as boarding instructions, service time, train estimated arrival and departure time, train timetable, etc., so that passengers can understand relevant information. Among them, accurate train estimated arrival and departure time is very important for passengers, so that passengers can arrange their time and itinerary reasonably.

[0041] However, when the train is assigned a train number after turning back, it is found that the earliest train number that can be assigned is not the next train number of the current service number. At this time, the train number assigned by the train should be the earliest train number with the current return track departure time. Therefore, the estimated arrival and departure time data calculated according to the planned data of the next train number of the current service number before turning back will be inaccurate.

[0042] In view of the above situation, the present disclosure provides a method for determining the arrival time of a train turning around in a subway system. Figure 1 FIG. 1 is a flow chart of a method for determining the arrival time of a train turnaround in a subway system according to an exemplary embodiment. Figure 1 As shown, the method for determining the arrival time of a train turning back in the subway system includes:

[0043] Step 10, determining a reversing train with the target reversing track as the destination of the current train when multiple trains are running;

[0044] Step 11, based on the order in which the reversing trains with the target reversing track as the destination of the current shift respectively arrive at the target reversing track, determining the train number of the next departure of the reversing train with the target reversing track as the destination of the current shift at the target reversing track;

[0045] Step 12: Based on the train number of the next departure of the return train on the target return track and the estimated arrival time of the return train at the target return track when the current train is running, determine the time information of the return train arriving at each station when the next departure is on the target return track.

[0046] In this exemplary embodiment, the method for determining the arrival time of a train turning around in the subway system of the present application can be applied to the calculation module of the PIS passenger information system in the ATS system, and is used when, when the scheduled train does not run according to the scheduled time in the timetable, the estimated arrival and departure times of each platform after turning around calculated before the turnaround are inaccurate, especially for the first two platforms after turning around, when there is no train running in the same direction, and the estimated arrival information of the train displayed by the passenger information system is only the estimated arrival and departure time after turning around calculated by the scheduled train still operating in the opposite direction, then the time information of the arrival of the turning train at each station when the turning train makes the next departure on the target turning track can be determined based on the method for determining the arrival time of a train turning around in the subway system of the present application.

[0047] In the present application, the train number of the next departure of the return train with the target reversing track as the destination of the current train is determined based on the order in which the return trains with the target reversing track as the destination of the current train arrive at the target reversing track respectively; the time information of the arrival of the return train at each station when the next departure is made on the target reversing track is determined based on the train number of the next departure of the return train on the target reversing track and the estimated arrival time of the return train at the target reversing track when the current train is running. This can ensure that when the reversing order of the return trains is confused, the train number of the next departure of the return train with the target reversing track as the destination of the current train can be determined based on the order in which the return trains with the target reversing track as the destination of the current train arrive at the target reversing track respectively, which is conducive to accurately estimating the time information of each return train arriving at each station when it departs next, thereby improving the accuracy of estimating the time information of each return train arriving at each station when it departs next.

[0048] In this exemplary embodiment, there may be multiple reversing tracks in the subway system, of which the target reversing track is one of them. A reversing train with the target reversing track as the destination of the current shift refers to a reversing train with the same target reversing track as the destination of the current shift. In this application, each reversing train has its own service number plus train number. For example, the first train is a service number plus a train number of 001202, 003204, and 005206, wherein 202, 204, and 206 are service numbers in the service list, and 001, 003, and 005 are train numbers in the train list; wherein a service number may contain multiple train numbers, for example, service number 202 contains train number 001, service number 204 contains train number 003, service number 206 contains train number 005, and so on. For example, when a train turns back, the first train is 001202 according to the original schedule, the second train is 003204 according to the original schedule, and the third train is 005206 according to the original schedule. However, due to some reasons, the train schedule is confused, causing the 003204 train to be delayed, and the 005206 train arrives at the target reversing track earlier than the 003204 train. At this time, it is necessary to reorder the order of each reversing train to the target reversing track, and arrange the first train as 001202, the second train as 005206 according to the original schedule, and the third train as 003204 according to the original schedule, etc. In this way, based on the schedule number of the reversing train for the next departure on the target reversing track and the estimated arrival time of the reversing train at the target reversing track when the current schedule is running, the time information of the reversing train arriving at each station when the target reversing track is next departed is determined.

[0049] In some embodiments, the determining of the time information of the arrival of the reentry train at each station when the reentry train makes the next departure on the target reentry track based on the train number of the reentry train for the next departure on the target reentry track and the estimated arrival time of the reentry train at the target reentry track when the current train is running includes:

[0050] Based on the train number of the return train for the next departure on the target return track, determine the planned time information of the return train corresponding to the train number arriving at each station when it departs next time;

[0051] Based on the planned time information of the return train corresponding to the shift number arriving at each station when it departs next time and the estimated arrival time of the return train at the target return track when running the current shift, the actual arrival time information of the return train at each station when it departs next time on the target return track is determined.

[0052] In this exemplary embodiment, the shift number is determined as the departure sequence number of the train line within the scheduled time. For example, 20 trains need to be dispatched from the train line within the scheduled time, including the first train, the second train, the third train, and so on. According to the departure sequence, each train corresponds to the planned arrival time, the planned departure time, and so on of each station. When determining the time information of the return train actually arriving at each station when the target return track is dispatched next time, it can be determined based on the planned time information of the return train corresponding to the shift number arriving at each station when the next departure is made, combined with the estimated arrival time of the return train at the target return track when the current shift is running, so as to facilitate the determination of the accurate time information of the return train actually arriving at each station when the target return track is dispatched next time.

[0053] In some embodiments, the time information of the actual arrival of the reentry train at each station when the target reentry track is operated next time based on the planned time information of the reentry train corresponding to the shift number when it departs next time and the estimated arrival time of the reentry train at the target reentry track when the current shift is operated, includes:

[0054] Determine the estimated departure time of the return train at the target return track for the next departure based on the estimated arrival time of the return train at the target return track during the current shift and the stop time of the return train at the target return track;

[0055] Based on the estimated departure time of the return train when it makes its next departure on the target return track and the planned departure time of the return train corresponding to the train number when it makes its next departure on the target return track, the actual arrival time information of the return train at each station when it makes its next departure on the target return track is determined.

[0056] In this exemplary embodiment, the estimated arrival time of the reversing train at the target reversing track during the current shift is accumulated to obtain the estimated departure time of the reversing train when it makes the next departure on the target reversing track. Then, based on the estimated departure time of the reversing train when it makes the next departure on the target reversing track and the planned departure time of the reversing train corresponding to the shift number when it makes the next departure on the target reversing track, the time information of the actual arrival of the reversing train at each station when the target reversing track makes the next departure is determined. This facilitates the determination of the accurate time information of the actual arrival of the reversing train at each station when the target reversing track makes the next departure.

[0057] In some embodiments, the time information of the actual arrival of the reentry train at each station when the target reentry train makes the next departure on the target reentry track based on the estimated departure time of the reentry train when the target reentry track makes the next departure and the planned departure time of the reentry train corresponding to the train number when the target reentry track makes the next departure, comprising:

[0058] If the estimated departure time of the return train when it makes its next departure on the target return track is consistent with the planned departure time of the return train corresponding to the train number when it makes its next departure on the target return track, the return train corresponding to the train number will depart based on the planned departure time of the next departure on the target return track, and the actual arrival time information of the return train at each station when it makes its next departure on the target return track is determined.

[0059] In this exemplary embodiment, for example, the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing is 9 o'clock, and the estimated departure time of the return train when the target return track is next departing is also 9 o'clock, then it is determined that the estimated departure time of the return train when the target return track is next departing is consistent with the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing. At this time, the time information of the return train actually arriving at each station when the target return track is next departing can be determined based on the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing.

[0060] In some embodiments, the time information of the actual arrival of the reentry train at each station when the target reentry train makes the next departure on the target reentry track based on the estimated departure time of the reentry train when the target reentry track makes the next departure and the planned departure time of the reentry train corresponding to the train number when the target reentry track makes the next departure, comprising:

[0061] If the estimated departure time of the return train when it makes its next departure on the target return track is inconsistent with the planned departure time of the return train corresponding to the train number when it makes its next departure on the target return track, the return train will make its next departure on the target return track based on the estimated departure time, and determine the actual arrival time information of the return train at each station when it makes its next departure on the target return track.

[0062] In this exemplary embodiment, the planned departure time of the return train corresponding to the train number when it makes the next departure on the target return track is 9:00, but the estimated departure time of the return train when it makes the next departure on the target return track is 9:03. Then, the actual arrival time of the return train at each station when it makes the next departure on the target return track may be delayed than planned. At this time, the return train makes the next departure on the target return track based on the estimated departure time, and determines the actual arrival time information of the return train at each station when it makes the next departure on the target return track.

[0063] In some embodiments, the time information of the actual arrival of the reentry train at each station when the target reentry train makes the next departure on the target reentry track based on the estimated departure time of the reentry train when the target reentry track makes the next departure and the planned departure time of the reentry train corresponding to the train number when the target reentry track makes the next departure, comprising:

[0064] If the estimated departure time of the return train when it makes the next departure on the target return track is inconsistent with the planned departure time of the return train corresponding to the shift number when it makes the next departure on the target return track, the waiting point operation is performed on the return train on the target return track, so that the return train corresponding to the shift number departs at the planned departure time when it makes the next departure on the target return track, and the time information of the actual arrival of the return train at each station when it makes the next departure on the target return track is determined; wherein the waiting point operation is an operation of performing the waiting point departure operation according to the planned time when the train arrives at the station or the target return track ahead of the planned time when it departs.

[0065] In this exemplary embodiment, the waiting point operation is to wait for the train to depart according to the planned time when the train arrives at the station or the target reversing track ahead of the planned time. For example, according to the train departure table, the first train leaves each station at 1 o'clock from the first station A, 2 o'clock from station B, and so on. If the first reversing train arrives at station A ahead of the planned time on the train departure table, it can wait for the point when leaving station A, and then leave the first station A at 1 o'clock. In this way, the reversing train that does not run on time can arrive and depart on time.

Figure 1 .like Figure 2 As shown in FIG. 1 , the process of determining the arrival time of a train turnaround in a subway system includes:

[0085] Step 42, looping through all the trains on the line that are not the current train;

[0086] Step 43: determine whether the circulating train is a planned train. If the current train is not a planned train, execute step 42;

[0087] Step 44: If the current train is a planned train, determine whether the destination of the loop train is consistent with the destination of the current train. If the destination of the loop train is inconsistent with the destination of the current train, execute step 42;

[0101] Step 57, if the first station and other points are configured, the arrival time of the first station is time B plus the planned running time from the reentry track to the first station after the reentry; among them, the expected departure time of the first station and the expected arrival and departure time of the subsequent stations are sent according to the planned data after the reentry;

[0102] Step 58: The estimated arrival and departure time of the first station and the subsequent stations are obtained by adding the deviation time after the return plan data; wherein, time A is compared with time C to obtain the deviation time after the return;

[0103] Step 59, end.

[0104] In this exemplary embodiment, the estimated arrival time of the current train at the reversing track is calculated and added to an ordered list. The trains that are not the current train among all the online trains are circulated, which is called a circulating train. The trains in the circulating train that are planned trains and whose destinations are consistent with the current train have their estimated arrival times at the destination reversing track calculated and added to the above-mentioned ordered list.

[0105] Among them, after the loop is completed, the ordered list is arranged in positive order according to the estimated arrival time, so that the ranking number of the current train in the ordered list can be obtained. The departure list is calculated first, which is obtained by calculating the timetable plan data. According to the departure track and departure time of each train in the timetable information, a list of trains grouped by different departure tracks can be obtained, and sorted in positive order according to the departure time. The status of all trains in the departure list is unassigned by default, and its status is changed to assigned when a train is assigned.

[0106] Among them, the ranking sequence number of the current train obtained by the above method is obtained from the departure list whose departure track is the destination track of the current train, and the train number information corresponding to the ranking sequence number is obtained according to the first unassigned train number. This train number information is the assigned train number information after the current train arrives at the return track.

[0107] The present invention provides a device for determining the arrival time of a train turnaround in a subway system. Figure 6 FIG. 1 is a schematic diagram of a device for determining the arrival time of a train turnaround in a subway system according to an exemplary embodiment. Figure 6 As shown, the device comprises:

[0108] The first information determination module 60 is used to determine the return train with the target return track as the destination of the current train when multiple trains are running;

[0109] The second information determination module 61 is used to determine the train number of the next departure of the reversing train with the target reversing track as the destination of the current train at the target reversing track based on the order in which the reversing trains with the target reversing track as the destination of the current train arrive at the target reversing track respectively;

[0110] The third information determination module 62 is used to determine the time information of the return train arriving at each station when it next departs on the target return track based on the train number of the return train for the next departure on the target return track and the estimated arrival time of the return train at the target return track when running on the current train.

[0111] In this exemplary embodiment, the device for determining the arrival time of a train turning around in the subway system of the present application can be applied to the calculation module of the PIS passenger information system in the ATS system, and is used to solve the problem that when the scheduled train does not run according to the planned time in the timetable, the estimated arrival and departure times of each platform after turning around calculated before the turnaround are inaccurate, especially for the first two platforms after turning around, when there is no train running in the same direction, and the estimated arrival information of the train displayed by the passenger information system is only the estimated arrival and departure time after turning around calculated by the scheduled train still operating in the opposite direction, then the time information of the arrival of the turning train at each station when the turning train departs next time on the target turning track can be determined based on the method for determining the arrival time of a train turning around in the subway system of the present application.

[0112] In the present application, the train number of the next departure of the return train with the target reversing track as the destination of the current train is determined based on the order in which the return trains with the target reversing track as the destination of the current train arrive at the target reversing track respectively; the time information of the arrival of the return train at each station when the next departure is made on the target reversing track is determined based on the train number of the next departure of the return train on the target reversing track and the estimated arrival time of the return train at the target reversing track when the current train is running. This can ensure that when the reversing order of the return trains is confused, the train number of the next departure of the return train with the target reversing track as the destination of the current train can be determined based on the order in which the return trains with the target reversing track as the destination of the current train arrive at the target reversing track respectively, which is conducive to accurately estimating the time information of each return train arriving at each station when it departs next, thereby improving the accuracy of estimating the time information of each return train arriving at each station when it departs next.

[0113] In some embodiments, the third information determination module is used to

[0114] Based on the train number of the return train for the next departure on the target return track, determine the planned time information of the return train corresponding to the train number arriving at each station when it departs next time;

[0115] Based on the planned time information of the return train corresponding to the shift number arriving at each station when it departs next time and the estimated arrival time of the return train at the target return track when running the current shift, the actual arrival time information of the return train at each station when it departs next time on the target return track is determined.

[0116] In this exemplary embodiment, the shift number is determined as the departure sequence number of the train line within the scheduled time. For example, 20 trains need to be dispatched from the train line within the scheduled time, including the first train, the second train, the third train, and so on. According to the departure sequence, each train corresponds to the planned arrival time, the planned departure time, and so on of each station. When determining the time information of the return train actually arriving at each station when the target return track is dispatched next time, it can be determined based on the planned time information of the return train corresponding to the shift number arriving at each station when the next departure is made, combined with the estimated arrival time of the return train at the target return track when the current shift is running, so as to facilitate the determination of the accurate time information of the return train actually arriving at each station when the target return track is dispatched next time.

[0117] In some embodiments, the third information determination module is used to

[0118] Determine the estimated departure time of the return train at the target return track for the next departure based on the estimated arrival time of the return train at the target return track during the current shift and the stop time of the return train at the target return track;

[0119] Based on the estimated departure time of the return train when it makes its next departure on the target return track and the planned departure time of the return train corresponding to the train number when it makes its next departure on the target return track, the actual arrival time information of the return train at each station when it makes its next departure on the target return track is determined.

[0120] In this exemplary embodiment, the estimated arrival time of the reversing train at the target reversing track during the current shift is accumulated to obtain the estimated departure time of the reversing train when it makes the next departure on the target reversing track. Then, based on the estimated departure time of the reversing train when it makes the next departure on the target reversing track and the planned departure time of the reversing train corresponding to the shift number when it makes the next departure on the target reversing track, the time information of the actual arrival of the reversing train at each station when the target reversing track makes the next departure is determined. This facilitates the determination of the accurate time information of the actual arrival of the reversing train at each station when the target reversing track makes the next departure.

[0121] In some embodiments, the third information determination module is used to

[0122] If the estimated departure time of the return train when it makes its next departure on the target return track is consistent with the planned departure time of the return train corresponding to the train number when it makes its next departure on the target return track, the return train corresponding to the train number will depart based on the planned departure time of the next departure on the target return track, and the actual arrival time information of the return train at each station when it makes its next departure on the target return track is determined.

[0123] In this exemplary embodiment, for example, the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing is 9 o'clock, and the estimated departure time of the return train when the target return track is next departing is also 9 o'clock, then it is determined that the estimated departure time of the return train when the target return track is next departing is consistent with the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing. At this time, the time information of the return train actually arriving at each station when the target return track is next departing can be determined based on the scheduled departure time of the return train corresponding to the shift number when the target return track is next departing.

[0124] The third information determination module is used to determine the actual arrival time information of the return train at each station at the target reversing track based on the expected departure time when the return train makes its next departure at the target reversing track, if the expected departure time of the return train at the next departure at the target reversing track is inconsistent with the planned departure time of the return train corresponding to the train number at the next departure at the target reversing track.

[0125] In this exemplary embodiment, the planned departure time of the return train corresponding to the train number when it makes the next departure on the target return track is 9:00, but the estimated departure time of the return train when it makes the next departure on the target return track is 9:03. Then, the actual arrival time of the return train at each station when it makes the next departure on the target return track may be delayed than planned. At this time, the return train makes the next departure on the target return track based on the estimated departure time, and determines the actual arrival time information of the return train at each station when it makes the next departure on the target return track.

[0126] The third information determination module is used to perform a waiting point operation on the target reversing track if the estimated departure time of the reversing train when it makes the next departure on the target reversing track is inconsistent with the planned departure time of the reversing train corresponding to the shift number when it makes the next departure on the target reversing track, so that the reversing train corresponding to the shift number departs at the planned departure time of the next departure on the target reversing track, and determine the time information of the actual arrival of the reversing train at each station when it makes the next departure on the target reversing track; wherein the waiting point operation is an operation of performing a waiting point departure operation according to the planned time when the train arrives at the station or the target reversing track ahead of the planned time when it departs.

[0127] In this exemplary embodiment, the waiting point operation is to wait for the train to depart according to the planned time when the train arrives at the station or the target reversing track ahead of the planned time. For example, according to the train departure table, the first train leaves each station at 1 o'clock from the first station A, 2 o'clock from station B, and so on. If the first reversing train arrives at station A ahead of the planned time on the train departure table, it can wait for the point when leaving station A, and then leave the first station A at 1 o'clock. In this way, the reversing train that does not run on time can arrive and depart on time.
