Optionally, the adjusting the operation plan of the target train in the plan operation chart corresponding to the track traffic section based on the unidirectional interruption section, the fault occurrence time and the target turn-back station includes:
Determining a first target train which is scheduled to run to the unidirectional interruption section in the scheduled running chart at the fault occurrence time, and determining a second target train which is scheduled to run to a first turning station in the scheduled running chart at the fault occurrence time, wherein the first turning station is a preface turning station corresponding to the interruption direction of the unidirectional interruption section in the target turning station;

the running directions of the first target train, the second target train and the third target train are the same as the interrupting direction.
Specifically, in the embodiment of the invention, a first target train of a first target train which is operated to a unidirectional breaking section at the fault occurrence time in a plan operation diagram corresponding to a track traffic section can be determined, a second target train which is operated to a first turning station at the fault occurrence time in the plan operation diagram can be determined, wherein the first turning station is a preface turning station corresponding to the breaking direction of the unidirectional breaking section in the closest target turning station to the unidirectional breaking section, a third target train which is operated to be operated between the first target train and the second target train in the train operation diagram is determined, then the operation plan of the third target train is adjusted to be respectively buckled and stopped at different first target stations and/or different target sections, the first target stations comprise all stations between the first turning station and the unidirectional breaking section, the target sections comprise sections between two adjacent stations between the first turning station and the unidirectional breaking section, and the operation directions of the first target train, the second target train and the third target train are identical to the breaking directions.
For example, the position corresponding to the first turnback station is a, the position corresponding to the unidirectional breaking section is B, station 1 and station 2 are further included between a and B, and the third target train includes train 1, train 2 and train 3, so that in the scene of unidirectional breaking, train 1, train 2 and train 3 can be respectively buckled and stopped in the sections between station 1, station 2 and station 1 and station 2.
Alternatively, since the second target train is traveling to the first turning station at the time of the occurrence of the failure, the traveling schedule of the second target train may be adjusted to be turned back at the first turning station.
It can be understood that the embodiment of the invention adjusts the operation plan of the third target train with the same operation direction as the interruption direction to be buckled and/or to be buckled and stopped in the section based on the unidirectional interruption section of the track traffic section, the fault occurrence time of the unidirectional interruption section, and the target turn-back station closest to the unidirectional interruption section, thereby effectively realizing the automatic adjustment of the operation plan of the affected third target train.
Optionally, the adjusting the operation plan of the target train in the plan operation chart corresponding to the track traffic section based on the unidirectional interruption section, the fault occurrence time and the target turn-back station further includes:

adjusting the operation plan of the fourth target train to turn back at the first turning-back station;
and the running direction of the fourth target train is the same as the interrupting direction.
Specifically, in the embodiment of the present invention, it may be determined that a fourth target train, which is scheduled to travel in the planned travel chart and has been launched but has not traveled to the first turning-back station at the time of occurrence of the failure, is first of all scheduled to travel, and then the travel schedule of the fourth target train is adjusted to be turned back at the first turning-back station, where the travel direction of the fourth target train is the same as the interruption direction.
For example, if the fourth target train includes the train 4 and the train 5 and the position corresponding to the first turning-back station is a, the operation schedule of the train 4 and the train 5 is adjusted to turn back at a so that the train 4 and the train 5 can turn back in sequence when they are operated to a.
It can be understood that the embodiment of the invention adjusts the operation plan of the fourth target train with the same operation direction as the interruption direction to be folded back at the first folding station by the unidirectional interruption section based on the track traffic section, the fault occurrence time of the unidirectional interruption section, and the target folding station closest to the unidirectional interruption section, thereby effectively realizing the automatic adjustment of the operation plan of the affected fourth target train.
Optionally, the adjusting the operation plan of the fourth target train to fold back at the first folding station includes:

wherein the departure time of the first partial train is earlier than the departure time of the second partial train.
Specifically, in the embodiment of the invention, a fourth target train which is scheduled to run in the scheduled running chart and has already been launched but has not yet run to the first turning station in the fault occurrence time can be firstly determined, then a turning-back interval corresponding to the first turning station is determined, and when the launching interval of the fourth target train is determined to be smaller than the turning-back interval, the fourth target train is divided into a first part train and a second part train according to a first proportion, then the running schedule of the first part train is adjusted to be turned back in the first turning station, and the running schedule of the second part train is adjusted to be in a train returning section, wherein the launching time of the first part train is earlier than the launching time of the second part train.
For example, the fourth target train includes a train 4 and a train 5, the position corresponding to the first turning-back station is a, and the departure interval between the train 4 and the train 5 is 5 minutes, the turning-back interval corresponding to the first turning-back station is 6 minutes, the first ratio is 1:1, and since the departure interval between the train 4 and the train 5 is smaller than the turning-back interval corresponding to the first turning-back station, the fourth target train is divided into two parts of trains according to the ratio of 1:1, for example, the first part of train is the train 4, the second part of train is the train 5, and the departure time of the train 4 is earlier than the departure time of the train 5, the operation plan of the train 4 is adjusted to turn back at the a, and the operation plan of the train 5 is adjusted to perform the train returning section.
Alternatively, the first ratio may be k:1, where k may be determined based on the turn-back interval corresponding to the first turn-back station and the departure interval of the fourth target train, and k may be determined, for example, by the following formula:
wherein,indicating the corresponding turn-back interval of the first turn-back station, h indicating the departure interval of the fourth target train,/>Representing an upward rounding.

wherein the running direction of the fifth target train is opposite to the interrupting direction.
Specifically, in the embodiment of the present invention, it may be determined that the operation plan in the planned operation map has been launched at the failure occurrence time and has passed through the fifth target train of the second turning station, wherein the second turning station is a subsequent turning station corresponding to the interruption direction of the unidirectional interruption section in the target turning station, and further, based on the operation plan adjusted by the fourth target train, the operation plan of the fifth target train is adjusted to be stopped at the second target station until the fourth target train turns back through the previous station of the second target station, or it is determined that the operation plan of the fifth target train keeps the original operation plan of the fifth target train unchanged, wherein the second target station is one station between the launch station of the fifth target train and the end point of the fifth target train.
For example, the fourth target train includes the train 4 and the train 5, the fifth target train includes the train 6, the position corresponding to the first turning station is a, and the train 4 turns back at the a, when the operation plan of the train 6 is adjusted, the train 6 needs to be stopped as necessary, so that the train 4 is guaranteed to pass through after turning back preferentially.

dividing the sixth target train and the seventh target train into a third part of train and a fourth part of train according to a second proportion, adjusting the operation plan of the third part of train to turn back at the second turning-back station, and determining that the operation plan of the fourth part of train keeps the original operation plan of the fourth part of train unchanged;
wherein the running directions of the sixth target train and the seventh target train are opposite to the interrupting direction.
Specifically, in the embodiment of the present invention, it may be determined that a sixth target train, which is scheduled to travel in the operation chart and has been launched at the failure occurrence time but has not traveled to the second turning station, and a seventh target train, which is scheduled to travel at the failure duration time and travels to the second turning station, are first launched at the failure duration time, and then the sixth target train and the seventh target train are divided into a third portion train and a fourth portion train according to a second ratio, and then the operation schedule of the third portion train is adjusted to be turned back at the second turning station, and it is determined that the operation schedule of the fourth portion train keeps the original operation schedule of the fourth portion train unchanged, wherein the operation directions of the sixth target train and the seventh target train are both opposite to the interruption direction.
For example, the sixth target train includes a train 7, the seventh target train includes a train 8, the corresponding position of the second returning station is C, the second ratio is 1:1, and the sixth target train and the seventh target train are divided into a third part of train and a fourth part of train according to the ratio of 1:1, for example, the third part of train is the train 7, the fourth part of train is the train 8, and the operation plan of the train 7 is adjusted to return at the position C, while the operation plan of the train 8 remains unchanged.
It should be noted that, the determination manner of the second ratio may be similar to that of the first ratio, which is not described herein.
It can be understood that the embodiment of the invention considers the train turning-back pressure in the direction opposite to the interruption direction, and the proportion of the turning-back train to the passing train is reasonably configured to relieve the train turning-back pressure, so as to realize the automatic adjustment of the running plans of the affected sixth target train and seventh target train.
The train operation diagram adjusting method provided by the invention is described below through a specific embodiment.
It should be noted that, in the embodiment of the present invention, an uplink unidirectional interruption of a certain line is taken as an example, fig. 2 is a schematic diagram of a unidirectional interruption section, a fault occurrence time and a station capable of turning back in a planned operation diagram provided by the present invention, and as shown in fig. 2, the fault occurrence time is T 0 The fault duration is LT, the unidirectional interruption zone isThe forefront nearest station of the station capable of returning is +.>The last turn-back station in turn-back stations is +.>Then for the small intersection in front of the fault isFor the minor intersections behind the fault are +.>
First, an uplink interrupt train is determined, and a train affected by the uplink interrupt train is buckled.
Specifically, for the upper train v, if its operation plan is T 0 Entering unidirectional interrupt sectionI.e.Indicating v entry->For a time greater than T 0 (where up represents up), then the subsequent trains following train v are all trains that need to be adjusted. Meanwhile, for train u, if it is +.>Then train u may be atThe turning-back is realized. Whereas the co-train between train v and train u needs to be at station +.>To->And the total of w stations are used for buckling. If l is greater than or equal to w, part of trains need to be buckled and stopped in the section of the adjacent station in w stations, and if l is less than w, the part of trains is in the section of +.>And the subsequent stations of the car are completed in sequence.
For example, fig. 3 is a schematic diagram of the train buckling with upward influence provided by the present invention, as shown in fig. 3, for trains a, b and c with upward running directions, it can be known that the trains belong to the trains v and u, respectively, and after the failure occurs, namely, at T 0 Then, the trains a, b and c are sequentially buckled and stoppedTo->Different stations between them.
And secondly, determining trains which can pass before the turn-back of the downlink small-traffic road.
Specifically, for the time T at which the fault occurs 0 Has been taken off and has passed the stationIs required to pass to the destination in the failed zone, i.e. +.>
For example, fig. 4 is a schematic diagram of the passing of a train in descending order, as shown in fig. 4, for a train d in descending direction, which is at the failure occurrence time T 0 Has been taken off and at T 0 Has passed throughIts operation is not subject to unidirectional interruption section +_ after failure occurs>Can be influenced by->The segment reaches the destination.
Further, determining an ascending small-crossing turn-back train and a turn-off train, and buckling an ascending passing train.
In particular, for cars which have been taken but have not been enteredUpstream train v of (i.e.)Then can be->The station makes a turn back. In this case, the foldback interval of the small-crossing foldback should be considered>
If it isThe train can turn back according to the original departure interval when the actual departure interval h of the train is smaller than the actual departure interval h of the train. Due to the extension of the turn-back time of the small traffic route, part of stations need to be buckled. Meanwhile, for the downlink straight-through train P, the train needs to be buckled and operated at the subsequent station according to the condition of the train buckling of the small-traffic turn-back train, and the train preferentially passes through the small-traffic turn-back train.
If it isAnd if the train speed is larger than the actual departure interval h of the train, part of the train returning sections without departure are needed so as to reduce backlog of the train with the small way in the ascending direction. Similar to the train with the slow moving return section, the return section and the small intersection are returned in a mode of k:1 from the first train with the return section.
For example, fig. 5 is a schematic diagram of the upward small-crossing train turning back provided by the present invention, as shown in fig. 5, for a train e whose running direction is upward, at the failure occurrence time T 0 Has been taken but has not yet enteredWhen it is moved to the turn-back stationCan turn back when in use.
And finally, determining the down small-traffic turn-back train and the passing train.
Specifically, for the time T at which the fault occurs 0 Departure and not arrival at the return stationAt T 0 After-drive and arrive at the return station +.>In order to relieve the pressure in the downward direction, it is necessary to turn back part of the train and pass through the other part of the train. Wherein, the foldback capacity of the foldback station can be adjusted by small intersections in a k-1 mode.
If the terminal of the train q has a certain parking condition, the train q may be parked at the terminal preferentially to relieve the downward return pressure.
For example, fig. 6 is a schematic diagram of turning back and passing through a down-road small-crossing train provided by the present invention, as shown in fig. 6, for a train f and a train g whose running directions are down, the train f is at the failure occurrence time T 0 Has been driven and is at T 0 When not reaching the turn-back stationTrain g is launched within fault duration LT and arrives at the return station within LT +.>Then for train f and train g by based on the return station +.>Is to determine the turning-back capacity of the train f at the turning-back station +.>Turning back the position, and allowing the train g to pass throughThe segment reaches the destination.
It can be understood that, in the train operation diagram adjustment method provided by the embodiment of the present invention, the adjustment principle for adjusting the operation plan of the target train includes: for a target train in an interruption direction corresponding to the unidirectional interruption section, the target train runs in a small-crossing way; and enabling the target train in the passing direction (the opposite direction of the breaking direction) of the fault section to run according to the original traffic route. In addition, the embodiment of the invention also considers the turn-back capability of the small crossing and the minimum service level of the large crossing, reasonably configures the proportion of the large crossing and adjusts the train bottom hooking plan.
Optionally, fig. 7 is a schematic flow chart of a method for scheduling inter-zone unidirectional slow traveling, as shown in fig. 7, where the method includes: firstly, confirming the occurrence position of the turnout fault according to the fault event, and further determining whether the caused influence is unidirectional interruption or bidirectional interruption. If the fault is one-way interruption, the fault duration time, the interruption interval position, the minimum turn-back time of the nearest turn-back station from the interruption interval and the turn-back tracking time are pre-judged. And secondly, calling a section unidirectional interruption operation diagram adjustment algorithm (the train operation diagram adjustment method provided by the invention), generating an operation diagram corresponding to the scene in interruption time, and issuing the operation diagram to a train automatic supervision system (Automatic Train Supervision System, ATS) for execution. And further continuously tracking the development of the fault event, and if normal traffic is recovered within the predicted fault duration, ending the adjustment. If the duration of the creep state is longer than the duration of the prejudged fault, the interruption duration is prejudged again after the last prejudgment time is reached, and the unidirectional interruption operation diagram adjustment algorithm is called again until the interruption is ended, and normal operation is restored.
