Description

  The present invention relates to a train operation interval control system and a train operation interval control device.

  Conventionally, in a system that controls the train operation interval, when a train delay occurs, the location of the delay is identified, a "delay time" indicating the degree of delay is calculated, and the preceding train causing the delay is immediately after A new target value of the operation interval, which is the time operation interval, to be secured between the following trains of the vehicle is set.

  For example, Patent Document 1 aims to avoid the delayed divergence phenomenon even if the reference operation interval that influences the operation plan is shortened in order to improve the transportation capacity of the line section, and the position and speed information and operation. Compare the diagrams to determine the delay, calculate the location of the delay and the degree of delay, and create a new operating interval to be secured between the delayed train and the train that immediately follows it. A target value is set, and the distance from the current position of the following train to the place where the delay occurs is determined according to the difference between the new driving time target of this succeeding train and the minimum driving time interval defined for the entire original section. Change the operation diagram for the following train locally so that the arrival time later than the arrival time scheduled in the original operation diagram for each point in between, the position of the following train and Speed control, After that, when the delayed train starts recovery operation, it is possible to prevent the delay from diverging backward by performing recovery operation for the following trains, so the minimum operation interval at the time of creating the original operation diagram is just marginal. A technology that can be set and enables higher-density train operation is disclosed.

  However, according to the above-described conventional technology, the stop time is shortened to the shortest time in the transition period until the completion of the recovery operation, but the shortest time should be set at the stop station by increasing or decreasing the number of passengers, for example. If the stop time increases or decreases, it should be adjusted according to the fluctuation. That is, when the number of passengers is large, the stop time should be set longer, and when the number of passengers is small, the stop time should be set shorter. For this reason, there is a problem that the shortest time to be set is not appropriate, there is room for high-density train operation, and the train delay time in the transition period until the delay recovery is completed is long.

Was operated with a train operation prediction unit that performs predictive, the operation prediction sent the train operation management apparatus and transmits a speed command to the subsequent train.

  According to the present invention, when a disturbance of the diagram occurs, a transient until the completion of the delay recovery is achieved when the delay recovery operation is performed with a small delay while ensuring the target operation interval between the preceding train and the following train.

The data stored in the route database and the vehicle database storage unit 16 is data necessary for the on-vehicle-based on-board control device to detect the position of the own train and perform speed control according to a command from the base device 1. is there.

  FIG. 4 is a diagram illustrating a configuration of the first embodiment of the base device 1, the train operation management device 2, the train operation interval control device 3, and the passenger number estimation device 4. The train operation management device 2 has an execution diagram for operating the train according to a predetermined schedule, and transmits “signal display information” and “train location information and speed information” to the train operation interval control device 3. . The train operation interval control device 3 includes a train operation prediction unit 30 and a database storage unit 31. The train operation prediction unit 30 includes a train travel prediction unit 32 and a stop time prediction unit 33. The database storage unit 31 includes an execution diagram database, a minimum stop time database for each station, a variable stop time database based on the number of passengers, and a minimum operation interval database for each station. The train travel prediction unit 32 obtains “signal display information” and “train presence line position and speed information” from the train operation management device 2 at a certain period, and predicts the travel of the preceding train 9 and the subsequent train 10. The “signal display information” is signal display information acquired in real time from the ground signal equipment. “Train location position and speed information” is “position information and speed information” transmitted by the succeeding train 10 and the preceding train 9. The stop time prediction unit 33 acquires each data from the “minimum stop time database of each station”, the “variable stop time database” and the “minimum operation time interval database of each station” in the database storage unit 31 to obtain the preceding train Predict 9 stop hours. The execution diagram database stores an execution diagram held by the train operation management device 2 transmitted at the start of operation on the day. When the “execution diagram” is disturbed and the operation is arranged, the contents of the change are transmitted.

  The passenger number estimation device 4 stores a previously planned OD (Origin Destination) table (plan), and updates this based on the “train arrival and departure results” received from the train operation management device 2 (OD). Table (update)). In addition, the OD table should just be memorize | stored by the table data according to day and time zone.

  Next, the operation of the train operation interval control system will be described. All trains traveling on the route are provided with an on-board controller 12 and a radio on-board station 11, similarly to the following train 10. The speed control unit 13 included in the on-board control device 12 acquires the detection speed from the speed detection unit 15, and uses the detected speed, the route data stored in the route database and the vehicle database storage unit 16, and the ground unit, for example. Based on the absolute position as a reference point, “position information and speed information” of the own train is calculated and generated. The generated “location information and speed information” of the own train is transmitted to the ground via the radio onboard station 11. On the other hand, on the ground, the wireless supervision apparatus 6 selects any one of the wireless base stations 8 according to the position of each train, and passes through the selected wireless base station 8 so that the radio onboard station of the train. 11 to communicate. The “position information and speed information” of the train received by the wireless base station 8 is received by the base device 1 via the wireless management device 6 and the network 5. The base device 1 manages “position information and speed information” of all trains in the jurisdiction area, and generates “train position and speed information” from “position information and speed information” of all trains. And the interval between trains is determined based on the “signal display information” received from the ground signal equipment, and “control information” is transmitted to each train. Here, the transmitted “control information” can exemplify the number of an entry-prohibited track circuit that each train should stop in order to secure an interval between a plurality of trains. In normal times, the train operation management device 2 transmits route output information, for example, a departure route, to the base device 1 so as to control the train according to the execution schedule that it holds.

  However, once the train schedule is disturbed, the operations of the preceding train 9 and the succeeding train 10 that are delayed trains are delayed from the execution schedule. When the train operation is delayed from the execution schedule and the execution schedule is disturbed, the operation is arranged and the change contents are transmitted. When the change contents are transmitted from the execution diagram of the train operation management device 2 to the execution diagram database of the database storage unit 31, the train operation interval control device 3 activates the train operation prediction unit 30, and the train operation prediction unit 30 Operation prediction of the preceding train 9 and the succeeding train 10 in which the delay has occurred is performed. The train travel prediction unit 32 predicts the travel of the preceding train 9 and the subsequent train 10 from the “position information and speed information” and “signal display information” of the preceding train 9 and the succeeding train 10 acquired from the train operation management device 2. . Furthermore, the stop time prediction unit 33 determines the “minimum stop time” to be secured at each stop station stored in the minimum stop time database of each station, and the number of passengers at the stop station obtained by the passenger number estimation device 4. Based on the “variable stop time” obtained from the “variable stop time database” and the data of the minimum operation interval database of each station, the stop time is predicted.

  The number of passengers estimation device 4 estimates, for example, the number of passengers at each station based on the past “database of passengers by time of day and day of the week” of each station, and the number of stops in the variable stop time database. Remember. Based on the result of the “train travel prediction” of the preceding train 9 derived as described above and the result of the “stop time prediction” of the preceding train 9, the “train operation prediction” of the preceding train 9 is performed. The succeeding train 10 can shorten the transition period until the completion of the delay recovery when performing the delay recovery operation while ensuring the target operation interval.

  FIG. 5 is a flowchart showing a procedure of train operation prediction performed by the train operation prediction unit 30 of the train operation interval control device 3. First, the processing is started, and “execution diagram”, “signal display information”, and “train position and speed information” are acquired (step S1), and “execution diagram” is compared with “train running results”. (Step S2), it is determined whether or not a delay has occurred (Step S3). If no delay occurs, that is, if the process branches to No in step S3, the process ends. When a delay occurs, that is, when branching to Yes in Step S3, the train operation prediction unit 30 is activated (Step S4), the first train of the delay is extracted (Step S5), and the train travel prediction is performed. (Steps S6 to S8). Thereafter, it is determined whether or not the leading train is running (step S6). When traveling, that is, when branching to Yes in step S6, the vehicle is advanced to the next station while maintaining the driving interval (step S7). When not traveling, that is, when branching to No in step S6, or when traveling and the train is advanced to the next station by the train traveling prediction and stops, “stop time” is predicted (step S8). . Based on the “estimated stop time” and the “estimated stop time” of the station obtained from the passenger number estimation device 4 based on the “minimum stop time” based on the “minimum stop time” and the “variable stop time” based on the number of passengers Predict the stop time at the station. Thereafter, it is determined whether or not the subsequent train 10 stops due to the influence of the preceding train 9 when traveling according to the prediction of the train travel prediction in steps S6 to S8 (step S9). When stopping, that is, when branching to Yes in step S9, the train traveling prediction is performed again (step S10). When not stopping, that is, when branching to No in step S9, or when the train travel prediction is performed again, it is determined whether or not the travel by the prediction of the target train has become one or more stations (step S11). When the travel by the prediction of the target train is not more than one station, that is, when branching to No in step S11, the process returns to step S6 and the train travel prediction is performed (steps S6 to S8). When the travel by the prediction of the target train is one station or more, that is, when branching to Yes in step S11, it is determined whether or not the prediction of all trains has been completed (step S12). When prediction of all trains is not completed, that is, when branching to No in step S12, the next train is extracted (step S13), and the process returns to step S6 to perform train travel prediction. When the prediction of all trains is completed, that is, when the process branches to Yes in step S12, the process ends.

  Here, since the prediction range is for one station, it is determined whether or not the travel by prediction of the target train is one station or more in step S11, but the present invention is not limited to this, and the prediction range is There may be two or more stations. Alternatively, the prediction range may be defined by time. In the case of defining by time, the prediction range is, for example, 10 minutes. When the prediction range is defined by time, in step S11, for example, it may be determined whether traveling by prediction of the target train is 10 minutes or more. Alternatively, the prediction range may be defined by the distance.

  FIG. 6 is a diagram showing the time change of the train position when the train operation interval control system according to the present invention is applied. In FIG. 6, the horizontal axis indicates time, and the vertical axis indicates the position on the route. A curve C1 shows the locus of the leading vehicle of the preceding train 9 in normal travel. T1 is the planned stop time. A curve C2 indicates the locus of the leading vehicle of the preceding train 9 when the preceding train 9 stops due to, for example, a vehicle failure and then recovers. When the locus of the leading vehicle of the preceding train 9 is the curve C2, even if the succeeding train 10 travels normally, the succeeding train 10 cannot enter the blockage B and stops. This is shown as curve 1 in Comparative Example 1. A curve C5 indicates the trajectory of the leading vehicle of the succeeding train 10 when the operation management system detects that the arrival of the preceding train 9 at the station 1 is delayed and stops for a while at the station 2. In this case, as shown by the curve C3, the vehicle travels at a low speed while avoiding being stopped by the brake, and when the operation management system detects that the preceding train 9 has departed from the station 1, it accelerates to the speed in the normal traveling. Run. This is Comparative Example 2. Curve C6 shows the trajectory of the leading vehicle of the subsequent train 10 when the subsequent train 10 stops at the station 2 until the operation management system detects that the preceding train 9 has left the station 1. This is Comparative Example 3.

  In the curve C4 when the present invention is applied, the operation prediction of the preceding train 9 and the stop time T1 'at the station 1 are predicted. By controlling the subsequent train 10 so that the preceding train 9 enters the block B at the timing of passing through the block where the station 1 exists, the arrival delay to the station 1 can be minimized. In this way, by predicting the stop time T1 ', the preceding train 9 can enter the block B at the timing of passing through the block where the station 1 exists. That is, by predicting the stop time T1 ', the slope of the curve C4 can be made appropriate, and the subsequent train 10 can enter the blockage B at the most preferable timing. Further, when the succeeding train 10 is controlled as indicated by the curve C4, the succeeding train 10 travels without stopping, so that the energy consumption can be reduced as compared with the case where the succeeding train 10 rises from the state where it is temporarily stopped as indicated by the curve C3.
