Abstract

PROBLEM TO BE SOLVED: To heighten operation efficiency by shunting one train to a shunting station on the basis of an equipment condition on a train diagram prepared track in the case of the generation of an inter-station cross at the time of preparing a train diagram in a single track area including a partial double track area and a shunting station with a sidetrack for train crossing. SOLUTION: When an inter-station cross is generated between stations 2, 3, a priority mode (limited express > express > local > out-of-service) by classification of trains is judged. Departure time from the station 2 and arrival time at the station 3 on a prepared diagram line are computed to shunt a train r1. The arrival time at the station 3 is computed again, and whether an inter- station cross is generated between the same stations as a proceeding train is checked. In the case of no inter-station cross, the computed time is defined, but in the case of an inter-station cross being still generated, the same processing is performed, and departure time from the station 2 and arrival time at the station 3 on the prepared diagram line are computed to shunt a train r2, thus dissolving the inter-station cross.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for creating a train diagram in a train diagram creating apparatus for automatically creating a train diagram.

[0002]

2. Description of the Related Art FIG.
Is a flowchart showing a conventional method for creating a train diagram shown in Japanese Patent Application Laid-Open Publication No. H10-209,873.

The operation of this flowchart will be described below. The operator selects one of the priority modes (uplink priority, downlink priority) and sets the priority mode (S
1) Instruct the starting station, starting time, and destination station of the train (S2). Based on the instructed station and departure time, and the basic travel time from the station to the next station (N station), the arrival time of the N station is calculated by equation (A) (S3).

[0004] N station arrival time = (N-1) departure time of the station: 10 basic travel times to N stations ... (A)

[0005] Here, it is determined whether or not the train diagram being created does not generate a cross between stations with the already created train diagram (at the same time, the upper and lower trains exist at the same place on the track) (S4). If there is no crossing between stations,
A train diagram up to the N station is created (S5), and if the N station is the destination station, the creation of the train diagram ends (S5).
6). If the N station is not the destination station, the departure time of the N station is calculated by equation (B) (S7).

Departure time at N station = arrival time at N station + base stop time at N station ... (B)

Then, the N station is updated to the station next to the N station (S
9). Thereafter, the above operation is repeated based on the updated N.

On the other hand, when a cross between stations has occurred,
The evacuation processing described later is performed in accordance with the instructed priority mode, and then the processing of (S5) to (S9) is performed.
If the train schedule being created is in the evacuation mode (the created train has priority), the departure time at the station of the created train line and the arrival time at the next station are calculated and changed to eliminate the crossing between stations (S10). ).

On the other hand, when the prepared train diagram is in the evacuation mode (the train currently being prepared has priority), the departure time of the prepared train at the next station is delayed until the arrival time of the next station of the prepared train to cross the stations. To eliminate. In addition, the time after the departure time of the already created train is also changed (S1).
1).

[0010]

Since the conventional method for preparing a train schedule is configured as described above, the crossing between stations is unconditionally avoided without taking into account the equipment conditions (partial double tracks on the traveling track). There was something. Also, it was necessary to check the priority mode one station at a time regardless of the train type. In addition, the cross between stations only checks once,
The crossing between stations with continuation trains was not considered.

The present invention has been made to solve the above problems, and checks a priority mode (up-priority, down-priority) in consideration of equipment conditions and a train type, or a crossing between stations with a continuation train diagram. Accordingly, it is an object of the present invention to obtain a train schedule creation method capable of improving operation efficiency by evacuating one of the trains to a refuge station.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, a first invention is to provide a train diagram in a single-track section including a refuge station having a refuge number line for a train crossing and a partial double-track section. In the train schedule creation method to automatically create, check the cross between stations with the already created train schedule when creating the train schedule, check the equipment conditions on the train schedule creation line when the cross between stations occurs, One of the trains that causes the crossing between the stations is evacuated to the evacuation station based on the equipment conditions.

According to a second aspect of the present invention, the creation of the train diagram is performed based on the train type.

A third invention is a method for automatically creating a train diagram in a single-track section including a refuge station having a shunt number line for a train crossing and a partial double-track section. The train crossing between the train and the station is checked, and the crossing between the stations between the station and the already created train diagram is checked.

According to a fourth aspect of the present invention, when a crossing between stations with a train that has already been made occurs, one of the trains is determined based on the priority of the train that has made the train and the train that has made the train. It is designed to be compared with the evacuation station.

Further, in the fifth invention, when an inter-station cross with the train already created train diagram occurs, the arrival time of the train next to the train train created train and the train already created train is calculated. On the basis of the arrival time, one of the trains that causes the crossing between the stations is evacuated to the evacuation station.

According to such a configuration, when an inter-station cross occurs, the validity of the inter-station cross can be determined, and a non-priority train can be evacuated to, for example, a station that can be evacuated before the traveling direction. .

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, Embodiment 1 of the present invention will be described. FIG. 1 is a flow chart showing the procedure of the train schedule creation method of the present invention. FIG. 2 is a diagram for explaining how to draw a diamond line on the diagram editing screen. The horizontal axis of the diagram editing screen indicates time, and the vertical axis indicates stations. 3 to 5
Is a diagram for explaining the evacuation processing when a cross between stations occurs, and ta1 to ta2 and tb1 to tb2 in the figure represent evacuation time.

Next, the operation will be described. For convenience of explanation, the stations include station 1 to station 5 (the direction from station 1 to station 5 is the upward direction), and station 2 and station 3 are evacuable stations. Also, a description will be given assuming that a down train train has already been created and an up train train has been newly created. A diagram editing screen shown in FIG. 2B is displayed on the display device by the computer.

First, as shown in FIG. 2 (b), the operator selects a train type (any of limited express, express, normal, and forwarding) on the diagram edit screen with a mouse, thereby instructing the train type. (S1). Next, as shown in FIG. 2 (c), one point (point P) on the horizontal line indicating the starting station of the train schedule created by the operator and one point (point Q) on the horizontal line indicating the destination station are designated with the mouse. By doing so, the starting station, the starting time (read by the horizontal coordinate of point P), and the destination station are recognized by the computer (S2). Based on the recognized station and departure time, and the basic travel time from the recognized station to the next station (station 2 as the N station), the computer calculates the arrival time of the N station by the equation (A). (S3).

Arrival time at station N = Departure time of station (N−1) Basic travel time to station N— (A)

Here, it is determined whether the diagram to be created does not cross the upper and lower stations with the already created train diagram (S4).

If there is no crossing between stations, or if there is a crossing between stations, if it is a double track section (S
9), as shown in FIG. 2 (d) (here, a case where no cross between stations is generated), a train line up to N station (station 2) is created (S5), and N station (station 2) If is the destination station, the creation of the train diagram ends (S6). If N station (station 2) is not the destination station, the departure time of N station (station 2) is calculated by equation (B) (S7). In this way, by checking the double track section as the equipment condition, the crossing between the stations is unconditionally avoided without considering the equipment condition (partial double track on the traveling track) as in the related art. Waste can be prevented.

Departure time of N station = arrival time of N station + base stop time at N station (B)

Subsequently, the computer updates the N station to a station next to the N station (station 3) (S8). Thereafter, the above operation is repeated based on the updated N. On the other hand, when a cross between stations occurs in a single track section as shown in FIGS. 3 to 5, the evacuation process described later is performed according to the specified train type, and then the processes of S5 to S8 are performed.

Next, the operation of the saving process will be described.
As shown in FIG. 3A, it is assumed that a train r1 and an inter-station cross have occurred between the stations 2 and 3. The priority modes according to the train type are set as priority express, express, normal, and forwarding (prior express>express>normal> forwarding) in priority order, and the priority mode according to the train type is determined at the time of crossing between stations (S10). FIG.
(A) Consider a case in which the train r1 and the train r2 are limited express trains and the train being created is normal. In this case, the train diagram created in S10 is in the evacuation mode, and the departure time of station 2 and the arrival time of station 3 of the created diagram are calculated using equations (C) and (D) to save the train r1. (S14).

Station 2 departure time = arrival time of train r1 at station 2 ... (C)

Station 3 arrival time = arrival time of station 3 calculated by equation (A) + (ta1-basic stop time at station 2) (D)

Where ta1 = arrival time of train r1 at station 2−arrival time of train created at station 2

Then, the arrival time of the next station (the arrival time of the above-mentioned station 3) is calculated again (S16), and it is checked whether or not an inter-station cross occurs between the same stations as the continuation train (S17). Here, if there is no cross between stations, the time calculated by the above formulas (C) and (D) is determined. FIG.
As shown in (b), when a crossing between the train r2 and the station still occurs, the processes from S10 to S14 are performed again, and the departure time of the station 2 and the arrival time of the station 3 of the created diamond line are calculated by the formula The evacuation for the train r2 is performed by calculating (E) and (F).

Station 2 departure time = arrival time of train r2 at station 2 ... (E) Station 3 arrival time = station 3 arrival time calculated by equation (D) + ta2 ... (F)

Where ta2 = arrival time of train r2 at station 2−departure time of station 2 at (C)

As a result, the crossing between the stations is eliminated by the sheltering as shown in FIG.

Next, as shown in FIG.
It is assumed that a cross between the train r1 and the station occurs between the station and the station 3. Here, a case is considered in which the trains r1 and r2 are ordinary trains, and the train being created is an express train. In this case, the prepared train diagram is in the evacuation mode in S10, and the train r1 is evacuated by delaying the departure time of the station r3 of the train r1 (prepared diagram) to the arrival time of the train d3 at the station 3. At this time, train r1 goes to station 3,
The vehicle stops for tb1 (arrival time of the train created at station 3-arrival time of train r1 at station 3), and thereafter, a delay time (tb1-basic stop time at station 3) occurs to the destination station. Accordingly, as shown in FIG. 4B, the delay time is added to the arrival / departure time of the corresponding part of the train line of the train r1 to correct the train line (S15).

Here, when a crossing between the train r2 and the station further occurs, the processes of S10 to S13 and S15 are performed again, and the time of the train r1 corrected from the departure time of the station 3 to tb2 (station Arrival time of train r1 of 3-train r of station 3
The delay time of (arrival time 2) is added to correct the time line.

Next, as shown in FIG.
It is assumed that a cross between the train r1 and the station occurs between the station and the station 3. Here, consider the case where the train r1 is limited express, the train r2 is normal, and the train being created is normal. In this case, S
The train diagram created by the step 10 is in the evacuation mode for the train r1, the conventional priority mode selection (S11) for the train r2 (priority mode change request), and this time the train r2 is in the evacuation mode. (S1
2).

As shown in FIG. 5B, the departure time of the station 2 and the arrival time of the station 3 of the created diagram are represented by the following equation (G).
(H).

Station 2 departure time = arrival time of train r1 at station 2 ... (G)

Station 3 arrival time = arrival time of station 3 calculated by equation (A) + (ta−basic stop time at station 2) (H)

Where ta = arrival time of train r1 at station 2 / arrival time of train created at station 2

Then, again at the arrival time of the next station (the above station 3
Arrival time) and check whether there is a crossing between the continuation train and the station. In FIG. 5B, an inter-station crossing occurs further, and the departure time of the train r2 (already created train) at the station 3 is delayed until the arrival time of the created train (station (3)) (the above (H)) to evacuate the train r2. I do. With the above operation, an arbitrary number of train diagrams in a single track section can be automatically created.

In the first embodiment, the number of stations is 5
Although the evacuation station is limited to the station 2 and the station 3, the same effect can be obtained even if the number of other stations and the evacuation station are set. In the above embodiment, the down train is created first, but the up train may be created first. Further, the train type is not limited to the type in the above embodiment, and may be another type. It should be noted that other priorities of the types may be similarly used.

[0043]

As described above, according to the first invention, a train diagram for automatically creating a train diagram in a single-track section including a refuge station having a refuge number line for a train crossing and a partial double-track section is provided. In the method, at the time of creating a train diagram, check the cross between stations with the already created train diagram, and when the cross between stations occurs, check the equipment conditions on the train diagram creation line, and based on the above facility conditions, One train that causes an inter-station cross is evacuated to the evacuation station, so if an inter-station cross occurs, the legitimacy of the inter-station cross is determined. It is possible to evacuate to a possible station, and there is an effect that a train schedule for evacuating a train to an evacuation station can be automatically created with good operation efficiency.

According to the second aspect of the present invention, the creation of the train schedule is performed based on the train type. Therefore, when a cross between stations occurs, the validity of the cross between stations is determined. A non-priority train can be evacuated to, for example, a station that can be evacuated before the traveling direction, so that there is an effect that a train schedule for evacuating the train to the evacuated station can be automatically created with high operation efficiency.

According to the third aspect of the present invention, there is provided a method for automatically creating a train schedule in a single-track section including a refuge station having an escape line for a train crossing and a partial double-track section. In addition to checking the cross between the trains that have already been created and the cross between stations, and checking the cross between stations with the train that has already been created between the above stations, if the cross between stations occurs, the validity of the cross between stations is checked. For example, a non-priority train can be evacuated to a station that can be evacuated before the traveling direction, for example, and there is an effect that a train schedule for evacuating a train to an evacuation station can be automatically created with good operation efficiency. .

According to the fourth aspect of the present invention, when a crossing between stations with the already-prepared train train occurs, the above-mentioned station is determined based on the priorities of the train-prepared train and the train of the continued train train. One train that causes an inter-cross is compared to the evacuation station, so if an inter-station cross occurs, the legitimacy of the inter-station cross is determined, and for example, a non-priority train can be evacuated, for example, ahead of the traveling direction. This makes it possible to automatically create a train schedule for evacuating the train to the evacuation station with good operation efficiency.

Further, according to the fifth aspect of the present invention, when a crossing between stations with the train already made train occurs, the arrival time at the next station of the train made by train train and the train made by train continued is calculated. Based on the calculated arrival time, one of the trains causing the inter-station cross is evacuated to the evacuation station, so if an inter-station cross occurs, the legitimacy of the inter-station cross is determined. For example, a train can be evacuated to a station that can be evacuated before the traveling direction, and there is an effect that a train schedule for evacuating a train to an evacuation station can be automatically created with high operation efficiency.
