Description

[0002] During the operation of the train, it may be affected by various factors such as locomotive, vehicle, line maintenance, signal, station access status, the technical level of the locomotive driver, passengers getting on and off, fire, social disasters and other subjective and objective factors, which may cause the train to be delayed.

[0003] A train delay may cause a chain reaction on the line. For example, a large delay of the preceding train will inevitably cause the delay of the following train, making the number of delayed trains increasing. Since the train is delayed at the previous station or section, it will inevitably cause a backlog of passengers at the next platform, which will extend the train's stop time and cause further delays. The disruption of running intervals, some trains are overcrowded, while others are undercrowded, will cause the passenger turnover of the station to lose balance, thus forming a vicious circle. The chaos in the operation order of a line will inevitably affect the operation of the transfer station and thus affect the operation of related lines.

[0068] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] Figure 1 It is a flow chart of the train operation adjustment method provided by the present invention, such as Figure 1 As shown, including:

[0070] Step 110, obtaining delay information of trains on the target line, wherein the delay information includes the number of delayed trains and / or the total delay time of each delayed train;

[0071] The target line described in the embodiment of the present application may specifically be a specific subway line or a specific railway line, and the embodiment of the present application does not make any limitation thereto.

[0072] In the embodiment of the present application, the train on the target line refers to a train running on the target line, and the delayed train refers to a train running on the target line and is delayed.

[0073] When a train on a target line is delayed, delay information is generated. The train delay information described in the embodiments of the present application may be obtained through a train automatic control system or other train control equipment.

[0074] In an optional embodiment, the delay information may include the total number of delayed trains on the target line, and may also include the sum of the delay times of each delayed train on the target line, or may include both the number of delayed trains and the sum of the delay times of each delayed train.

[0075] Step 120, when it is determined that the delay information meets the preset adjustment conditions, adjusting the running interval of adjacent trains on the target line; wherein the running interval adjustment includes at least one of the following: forward adjustment, backward adjustment, and forward and backward adjustment;

[0076] The preset conditions described in the embodiments of the present application may be related to the number of delayed trains on the target line, or to the total delay time of the delayed trains on the target line.

[0077] In an optional embodiment, the preset adjustment condition may be that the number of delayed trains on the target line exceeds a first preset threshold.

[0078] In another optional embodiment, the preset adjustment condition may also be that the sum of delay times of delayed trains on the target line exceeds a second preset threshold.

[0079] In an embodiment of the present application, one is a situation where subsequent trains are clustered due to a significant delay of a certain train, and the number of subsequent clustered trains exceeds a first preset threshold. Another is a situation where subsequent trains are clustered due to significant delays of several trains, and the number of subsequent clustered trains exceeds a first preset threshold. The first preset threshold can be a certain proportion of the total number of trains on the target line, for example, 60% of the total number of trains on the target line.

[0080] In an optional embodiment, the delay situation of the target line may also be determined by analyzing the total delay time of trains on the target line.

[0081] Assuming that the delay of a train causes the delay of subsequent trains, whether the train needs to stop outside a station is determined by the train's running interval and the planned stop time at a station. d >(μ-t max )*n*0.6, where n is the total number of trains on the line, t max is the maximum stop time among all stations, π is the train tracking interval, then the train may cause trains on the target line to stop outside the station exceeding the first preset threshold.

[0082] For the problem of subsequent train delays caused by major delays of multiple trains, the delay time of the delayed trains that stop outside the station will be accumulated to obtain the total delay time. If the total delay time of leaving the station is greater than the second preset threshold (π-t max )*n*0.6, then the sum of trains stopping outside the station caused by delayed trains may exceed the first preset threshold.

[0083] In the embodiment of the present application, the train interval adjustment has the following adjustment modes: forward adjustment, backward adjustment, and forward and backward adjustment. Forward adjustment refers to adjusting the interval between two adjacent trains by adjusting the front car of the two adjacent trains, backward adjustment refers to adjusting the interval between two adjacent trains by adjusting the rear car of the two adjacent trains, and forward and backward adjustment refers to adjusting both the front and rear cars to achieve the purpose of changing the interval. The main difference between different adjustment modes is that the time required to achieve the same train interval is different.

[0084] In an optional embodiment, the impact of delays is reduced in the embodiments of the present application, that is, the timetable is adjusted mainly from the two perspectives of stop time and expected interval running time. If the stop time is adjusted, it may affect the passengers' boarding and alighting time, for example, waiting longer or insufficient time to board. Therefore, in order to reduce the passengers' perception of the train's automatic adjustment process, the present application will give priority to adjusting the train's interval running time. If the deviation cannot be fully restored, the stop time at the current station of the train will be considered.

[0085] In the embodiment of the present application, the specific method of adjusting the interval running time of the train is to adjust the running interval of adjacent trains on the target line.

[0086] Step 130, when it is determined that the interval deviations between the adjacent trains on the target line are all less than a preset threshold, stop adjusting the interval; wherein the interval deviation is the difference between the actual interval and the planned interval.

[0087] In the embodiment of the present application, the driving interval deviation may specifically refer to the difference between the actual driving interval and the ideal planned driving interval.

[0088] The planned train interval in the embodiment of the present application may specifically be that when the automatic adjustment mode of the train interval is started, the required train interval will be input into the same dialog box. The train interval of the current timetable will be used as the initial value, and the operator can change this value. A train interval calculation is automatically performed to calculate the ideal planned train interval. The planned train interval is the quotient of the time it takes for a train to complete an up and down trip and the current number of trains. Since the travel speed of the train varies within a range, the calculated ideal planned train interval is a range, and the operator can select a suitable value within this interval as the planned train interval.

[0089] The actual train running interval in the embodiment of the present application may specifically be the arrival time of the previous train minus the arrival time of the current train between two adjacent trains.

[0090] In the embodiment of the present application, when the driving interval deviations between each of the adjacent trains on the target line are less than the preset threshold, it means that the adjustment of the driving interval has achieved a good effect at this time, and the driving interval adjustment can be stopped at this time.

[0091] In an optional embodiment, if the delay in the target line is still serious at this time, the stop time of the train can be further adjusted.

[0092] When reducing stop times, the minimum stop time can be taken into account, and the stop time cannot be lower than its minimum value. When increasing stop times, the maximum stop time must be taken into account, and the stop time cannot be higher than its maximum value. When driving times are reduced or increased, the minimum and maximum driving times can also be taken into account. It is used to ensure that the driving time does not deviate from this range of minimum driving time and maximum driving time. In order to ensure that gaps are filled as quickly as possible, a special maximum stop time value and maximum interval running time will be configured; this value is higher than the maximum value used in the timetable adjustment.

[0093] In an embodiment of the present application, by analyzing the delay information of trains on the target line, when the delay information meets the preset adjustment conditions, it is determined that the trains on the target line are greatly affected at this time. By taking all trains on the target line as adjustment objects, the running intervals between trains are further adjusted, thereby effectively reducing the impact of train delays on the operation of the target line, restoring the trains to run according to the schedule in the shortest time, and improving the travel comfort of passengers.

[0094] Optionally, the adjusting the running interval of adjacent trains on the target line includes:

[0095] For any adjacent train on the target line, based on the difference in arrival time between the front train and the rear train in the adjacent train, determine the actual running interval of the adjacent train;

[0096] Obtaining a running interval deviation of the adjacent trains according to a difference between a planned running interval and an actual running interval of the adjacent trains;

[0097] Based on the train headway deviation, the train headway of each group of adjacent trains on the target line is adjusted.

[0098] In the embodiment of the present application, the actual headway interval (RIHW) between adjacent trains is: the arrival time of the previous train minus the arrival time of the current train:

[0099] RIHW = arrival time (current train) – arrival time (previous train)

[0100] In the embodiment of the present application, the running interval deviation between adjacent trains may specifically be:

[0101] HWD=RIHW–PIHW

[0102] RIHW represents the actual headway, and PIHW represents the planned or required headway. Thus, if the headway is too small, the headway deviation will be a negative number (HWD<0); if the headway is too large, the headway deviation will be a positive number (HWD>0).

[0103] In the embodiment of the present application, the train interval adjustment is performed only when the train interval deviation is very significant, for example, when the train interval deviation between adjacent trains exceeds the third preset threshold.

[0104] The third preset threshold in the embodiment of the present application may be a threshold set according to demand and may be continuously adjusted.

[0105] The train interval adjustment must be used globally on the target line and cannot be used only at one station or a few local stations. Therefore, after completing the train interval adjustment for adjacent trains, you can continue to adjust another group of adjacent trains until all adjacent trains on the target line are traversed.

[0106] In the embodiment of the present application, whether the interval deviation between adjacent trains on the target line exceeds a third preset threshold value is determined to determine whether the interval adjustment is needed, thereby effectively improving the accuracy of the interval adjustment. After completing the interval adjustment of the adjacent trains, another group of adjacent trains is adjusted, traversing all adjacent trains on the target line, effectively realizing global adjustment of the interval, and fully reducing the impact of delays on the target line.

[0107] Optionally, when the train headway adjustment is a forward adjustment, adjusting the train headway of adjacent trains on the target line based on the train headway deviation includes:

[0108] When it is determined that the train interval deviation is a positive value, controlling the leading train in the adjacent trains to decelerate according to the train interval deviation, so as to adjust the train interval of the adjacent trains;

[0109] When it is determined that the train interval deviation is a negative value, the leading train in the adjacent trains is controlled to accelerate according to the train interval deviation to achieve adjustment of the train interval for the adjacent trains.

[0110] In the embodiment of the present application, the forward adjustment will not adjust the rear train in the adjacent train, but will act on the train in front of it. If the headway deviation is positive (HWD>0), that is, the headway is too large, the preceding train will slow down, so the correction amount is positive (HWC>0).

[0111] On the contrary, if the headway deviation is negative, the preceding train will accelerate, so the correction will be negative (HWC<0).

[0112] Therefore, in the case of forward adjustment, the adjustment correction amount is specifically: HWC=HWD.

[0113] Optionally, when the train headway adjustment is a backward adjustment, adjusting the train headway of adjacent trains on the target line based on the train headway deviation includes:

[0114] When it is determined that the interval deviation between the adjacent trains is a positive value, controlling the rear train in the adjacent train to accelerate according to the interval deviation between the adjacent trains, so as to adjust the interval between the adjacent trains;

[0115] When it is determined that the interval deviation between the adjacent trains is a negative value, the rear train in the adjacent trains is controlled to decelerate according to the interval deviation, so as to adjust the interval between the adjacent trains.

[0116] The backward adjustment will affect the current train. If the headway deviation is positive (HWD>0), that is, the headway is too large, the current train will accelerate, so the correction amount is negative (HWC<0). Conversely, if the headway deviation is negative, the current train will decelerate, so the correction amount is positive (HWC>0).

[0117] Therefore, in the case of backward adjustment, the adjustment correction amount is specifically: HWC=-HWD.

[0118] Optionally, when the train headway adjustment is forward and backward adjustment, adjusting the train headway of adjacent trains on the target line based on the train headway deviation includes:

[0119] According to the running interval deviation of the adjacent trains, obtaining the forward adjustment correction amount and the backward adjustment correction amount of the adjacent train;

[0120] Determining the forward and backward correction amounts of the adjacent train according to the forward adjustment correction amount and the backward adjustment correction amount;

[0121] Based on the forward and backward correction amount, the front train and / or the rear train in the adjacent trains are controlled to adjust the running interval.

[0122] In the embodiment of the present application, the forward and backward adjustment specifically means that the forward adjustment and backward adjustment of adjacent trains are both activated, so the front and rear trains of the adjacent trains will have corresponding adjustment correction amounts.

[0123] The correction amount for the forward and backward adjustment of the train is equal to the sum of the forward adjustment correction amount and the backward adjustment correction amount divided by 2.

[0124] In the embodiment of the present application, in an optional embodiment, the correction amount for backward adjustment is calculated when the current train enters the station. The correction amount for forward adjustment is calculated when the train after the current train last enters the station. The calculation method of the correction amount for forward adjustment and the correction amount for backward adjustment can refer to the calculation method in the embodiments of forward adjustment and backward adjustment in the above embodiments, which will not be repeated here.

[0125] In an optional embodiment, after the forward adjustment amount is calculated, the position of the preceding vehicle needs to be detected. If the preceding vehicle is at a station, the stopping time and interval running time of the preceding vehicle need to be recalculated. If the preceding vehicle is at an interval, the time needs to be saved and queried when the preceding vehicle arrives at the station.

[0126] Optionally, based on the forward and backward correction amount, controlling the leading train and / or the trailing train in the adjacent trains to adjust the running interval includes:

[0127] When the forward adjustment correction amount is a positive value, the leading vehicle in the adjacent train is controlled to accelerate according to the forward and backward correction amount, or when the forward adjustment correction amount is a negative value, the leading vehicle in the adjacent train is controlled to decelerate according to the forward and backward correction amount;

[0128] When the backward adjustment correction amount is a positive value, the rear vehicle in the adjacent train is controlled to accelerate according to the forward and backward correction amount, or when the forward adjustment correction amount is a negative value, the rear vehicle in the adjacent train is controlled to decelerate according to the forward and backward correction amount.

[0129] In an embodiment of the present application, when the forward adjustment correction amount is a positive value, the front car in the adjacent train is controlled to accelerate according to the forward and backward correction amount, or when the forward adjustment correction amount is a negative value, the front car in the adjacent train is controlled to decelerate according to the forward and backward correction amount; at the same time, when the backward adjustment correction amount is a positive value, the rear car in the adjacent train is controlled to accelerate according to the forward and backward correction amount, or when the forward adjustment correction amount is a negative value, the rear car in the adjacent train is controlled to decelerate according to the forward and backward correction amount.

[0130] In an optional embodiment, in the case of mixed routes, if the running interval adjustment is used, first, a part of the trains need to return to the depot to ensure that the number of trains on the line is equal to the number of trains on the original large route. The vehicles returning to the depot are not necessarily trains on the small route. The number of trains should be restored to the number of trains on the large route as soon as possible according to the principle of proximity. These require manual participation. Then the running interval adjustment is used for the trains on the large route. The specific adjustment method is consistent with the method of adjusting the running interval of a single route. In the end, it is not necessary to restore the trains to the operating conditions of the large and small routes, as long as the plan diagram is restored to the state without the small route trains.

[0131] Figure 2 A disturbance adjustment schematic diagram provided in an embodiment of the present application, such as Figure 2 As shown, it includes: the vertical lines on the horizontal axis represent the train interval required to achieve the running interval. The dots represent the current train positions.

[0132] Train T0 is an interference train. Its stop time at the previous station is seriously exceeded. The trains after train T0 (T11, T12, T13) are constrained: the intervals between the bicycles of trains T0, T11, T12, T13 are too small. On the other hand, the distance between T0 and the train T21 in front of it is large. In order to shorten this distance, it is necessary to slow down train T21 and speed up train T0. In addition, it is necessary to slow down trains T11, T12, T13 after T0.

[0133] For T21, the interval between T0 and T21 is too large, while the interval between T21 and T22 is normal. The forward adjustment of T0 decelerates T21. The deceleration of T21 causes the interval between T21 and T22 to increase. The next backward adjustment will be activated to accelerate T21.

[0134] For train T0, the backward adjustment and forward adjustment have the same effect. This train accelerates. In this case it uses the accumulated value of the forward adjustment and the backward adjustment / 2.

[0135] For the trains (T11 and T12), the forward adjustment and the backward adjustment produce opposite corrections. In this case, the cumulative value of the forward adjustment and the backward adjustment / 2 will be used.

[0136] The last of these trains, T13, was only adjusted backwards, resulting in a positive correction and the train slowing down.

[0137] In the embodiments of the present application, the present application can effectively adjust the planned running interval of adjacent trains on the target line through various adjustment methods such as forward adjustment, backward adjustment, forward and backward adjustment, etc., thereby effectively alleviating delays on the target line.

[0138] Optionally, after stopping the driving interval adjustment, the method further includes:

[0139] After the train interval adjustment of the target line is completed, the minimum deviation train in the target line is obtained; wherein the minimum deviation train is the train in the target line with the minimum deviation from the preset plan line;

[0140] The train number of the minimum deviation train is replaced with the train number of the corresponding baseline, and the train numbers of the trains before and after the minimum deviation train are modified in sequence to complete the replacement of the train number for the target line.

[0141] In the embodiment of the present application, after the train interval adjustment is taken, when the intervals between trains are relatively balanced, it is generally necessary to change the train number and offset the schedule so that the interval adjustment can be transitioned to the schedule adjustment. After the interval adjustment is completed, the train number is first replaced to assign a suitable train number to the trains with similar deviations, and then the original schedule is offset to make the actual operation of the train close to the planned diagram.

[0142] In an embodiment of the present application, after completing the adjustment of the train interval, find the train with the smallest deviation from the planned line among all the trains on the line as the reference train, and its corresponding planned line is the reference line. The train number of the reference train is replaced with the train number of the corresponding baseline, and then the train numbers of the front and rear trains are modified in sequence.

[0143] In the embodiment of the present application, by adjusting the timetable, the problem of long passenger travel time caused by train delays is further reduced, thereby effectively improving the passenger travel experience.

[0144] Optionally, after completing the train number change for the target line, the method further includes:

[0145] Determining an offset adjustment time based on a deviation time between the minimum deviation train and the baseline;

[0146] The timetable of the target route is adjusted based on the offset adjustment time.

[0147] In the embodiment of the present application, when the train is delayed as a whole and close to the planned line, a time can be found before this time that is basically consistent with the running status of the current train. The original planned line can be translated as a new implementation line, and the train only needs to adjust the schedule or not. The time of schedule offset is the deviation time between the reference car and the baseline after the train number is changed.

[0148] In the embodiment of the present application, by adjusting the timetable, the impact of delays on train operations can be effectively mitigated, thereby minimizing the adverse riding experience caused by delays.
