DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train timetable creating device for automatically creating a train timetable, and more specifically, a train timetable creating device capable of more rationally setting train connection / disconnection in a single track section. Regarding

[0002]

2. Description of the Related Art FIG. 8 is a block diagram showing a configuration of a conventional train schedule creating apparatus disclosed in Japanese Patent Laid-Open No. 61-70574.

In FIG. 8, reference numeral 1 indicates an electronic computer, to which a terminal device 2 for inputting / outputting characters, a display device 3 for displaying character information / train diagram, and a storage device 5 are connected. Further, the display device 3 is connected to an input device 4 for coordinate positions, characters, numerical values, instruction commands and the like.

In such an apparatus, a train schedule is created as follows. First, attributes such as the number of trains, train type, number of cars, etc. of the train diagram that the operator wants to create, the departure time width of the first station of each train, the maximum allowable stop time, the maximum allowable operating time, and the conditions regarding evacuation and overtaking at each station And the like are input to the electronic computer 1 via the terminal device 2.

The electronic computer 1 refers to conditions such as track data stored in advance in the storage device 5 in accordance with the train setting conditions instructed via the terminal device 2 and refers to the same direction (only if it is an uplink, only an uplink. , Trim and error by paying attention to the combination of train order if it is a descending train), the relationship between the evacuation and passing of trains in the same direction in the form of a train diagram, the settable time range of each train A draft is created and displayed on the display device 3. The operator can set and correct the details of the original train schedule displayed on the display device 3 by using the input device 4 or the like.

[0006]

By the way, in the conventional train schedule creation device as described above, trial and error is made by paying attention to the combination of train orders in the same direction (only ascending when going up, only going down when going down). Therefore, the computer 1 does not consider the connection / disconnection between the upper and lower trains at all. this is,
This is because the train schedule creation device described above is premised on the creation of a train schedule in a double-track section. Therefore, when a train schedule for a single-track section is created by the train schedule creating device described above, a state in which an up train and a down train run on the same track between two stations (at such a state Cross) occurs. Such a cross between stations means the occurrence of a frontal collision between upper and lower trains.Therefore, when creating a train schedule for a single track section, in order to avoid crossing between stations, the upper and lower trains should be separated from each other. It is necessary to avoid a frontal collision by having a train wait for the other train to pass.

In the above-mentioned conventional train timetable preparation device, since the connection / disconnection between the upper and lower trains is not taken into consideration, when the conventional train timetable preparation device prepares the train timetable of the single track section, the input device 4 is used. It is necessary for the operator to correct the train schedule by trial and error while taking into consideration the coupling of upper and lower trains. For this reason, it takes a lot of time to create a train schedule for a single-track section by the conventional train schedule creating apparatus, and only a trained person can create the train schedule. There is no point in using.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a train schedule creation device capable of automatically creating a train schedule in consideration of the crossing between stations in a single track section.

[0009]

According to the present invention, a train schedule creating apparatus sets a train schedule in accordance with given conditions by a computer when automatically creating a train schedule for a single track section. It is determined whether the train schedule and the preset train schedule in the other direction will cause a cross between stations.If it is determined that a cross between stations will occur, a newly set train will be available at a station where the preset train can be detached. Calculate the stop time required for decoupling and the stop time required for a previously set train to depart a newly created train at a station where it can be decoupled, and perform a decoupling at the station with the shorter stop time. Is configured to fix.

[0010]

In the train schedule creation device of the present invention, it is determined whether or not the newly set train schedule and the preset train schedule in the other direction will cause an inter-station cross, and it will be determined that an inter-station cross will occur. In case of a new set train, the stop time required for the newly set train to connect and disconnect at the station where the existing set train can be connected and the stop time necessary for the already set train to connect and disconnect the newly created train at the station that can connect and disconnect are calculated. The train schedule of the single-track section is automatically created while avoiding the occurrence of crossing between stations by correcting the train schedule so that the train station is connected and disconnected at the station where the stop time is shorter.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing the embodiments.

The train schedule creating device according to the present invention basically uses the same device as the device shown in FIG. 8 described in the above-mentioned conventional example. FIG. 1 is a flowchart showing a processing procedure by the train schedule creation device according to the present invention, and FIG. 2 is a schematic diagram showing a state of a schedule edit screen 6 displayed on the display device 3.

First, the electronic computer 1 first displays a timetable edit screen 6 as shown in FIG.
To be displayed. This timetable edit screen 6 displays each station as time on the horizontal axis and X coordinate on the vertical axis. In this embodiment, the number of stations is 5 stations from the 1st station to the 5th station, and the 2nd station and the 3rd station of these stations, which are marked with ●, are releasable stations.

Next, the operator gives an instruction of the starting station, the starting time and the destination station via the input device 4 (step S1). Specifically, on the timetable edit screen 6, the operator first designates an arbitrary point, for example, point A in FIG. 3 with an input instruction device such as a mouse, so that the starting station and the starting time are input. Next, the station to be set as the destination station, for example, the fifth station in FIG. 3 is designated by the mouse. The destination station may be designated by pointing to any of the points on the Y coordinate where the fifth station is located. .

Next, the setting of a new train schedule is performed by the electronic computer 1 (step S2). Specifically, it is as follows. When the operator finishes instructing the starting station, the starting time, and the destination station, the electronic computer 1 recognizes the X coordinate of the instructed point A as the starting time and the Y coordinate as the starting station. Calculate the arrival time and departure time at each station of the train schedule based on the basic stop time data at each station and the basic travel time data at each station stored in the specified destination station (in this case Sets a new train diamond line up to the 5th station (step S3). As shown in FIG. 3, the result is displayed as a streak between points A and B on the diamond edit screen 6 of the display device 3.

In this way, at the stage where the new train diamond is set, it is determined whether or not the new train diamond has not crossed the station with the previously created train diamond that has been set before (step S4). ). If the station cross has not occurred, the process proceeds to step S10, which will be described later, and the setting of one new train diamond line is completed. If the station cross has occurred, the following steps are performed.
The process proceeds to S5 and the process for avoiding the crossing between stations is performed.

While FIG. 3 described above shows a state in which a cross between stations has not occurred, FIG. 4 shows a state in which a cross between stations has occurred. That is, as described above, after the up train stripe having the first station as the starting station and the fifth station as the destination station is set, the fifth station indicated by the point C is set as shown in FIG. When the starting train station and the starting train time are set, and a down train line having the first station as the destination station is set, a new train diamond line is set. However, an already-created train Diassi going from the 1st station to the 5th station and a new train Diassi going from the 5th station to the 1st station will cause an inter-station cross at the point D between the 2nd station and the 3rd station. ing.

By the way, at each station between the first station and the fifth station, as described above, the second station and the third station can be joined (●
Is assigned to each station), and this condition is stored in the storage device 5 in advance. Therefore, when a crossing between stations as shown in FIG. 4 occurs, the electronic computer 1 can connect and disconnect at both sides of the occurrence point (Y coordinate) (in this case, the second station and the third station). On the other hand, first, the stop time in the case of connecting and disconnecting is calculated. Specifically, as shown in FIG. 5, the electronic computer 1 stops the upstream train when the upstream train waits at the second station, which is one of the detachable stations, and the downstream train is preferentially passed through. First, the time ta is calculated by the following formula (step S5).

Ta = "arrival time of the down train to the second station"
-"Arrival time of the up train to the second station"

Next, as shown in FIG. 6, the electronic computer 1 makes a down train stand by at the third station which is the other detachable station and preferentially passes the up train. The stop time tb of is calculated by the following formula (step S6).

Tb = "arrival time of up train to the third station"
-"Arrival time of down train to Station 3"

The electronic computer 1 compares the above ta and tb and selects whichever is smaller, corrects the arrival time and departure time at each station of both train diamonds according to this result, and It is displayed on the timetable edit screen 6 of the display device 3 (step S7). In the example shown in FIG. 5 and FIG. 6, since ta <tb, the departure / arrival at the second station is selected, and as a result, the delay time at the second station expressed by the following formula is used for the up train. td occurs.

Td = ta- "basic stop time of the up train at the second station"

Therefore, for the up train, the electronic computer 1 resets the train diamond by adding the above-mentioned delay time td to the departure time and the arrival time at each station between the second station and the fifth station. In this case, modification of the train schedule for the down train is unnecessary. FIG. 7 shows a state in which two train diamond lines have been created in this way.

By the way, since there is a possibility that the train schedule corrected as described above may cause a new station train crossing to occur between stations, the computer 1 judges the possibility (step S8). ). Then, when the newly created train schedule is modified as described above, if this causes a new station cross with another already-created train schedule, the computer 1 returns the process to step S4. , Processes the newly generated cross between stations.
On the other hand, when the already-created train diamond is modified as described above, if this causes a new station-to-station cross with another already-created train diamond, the computer 1 advances the process to step S9. If the corrected train schedule does not cause a new crossing between stations, the computer 1 advances the process to step S10 and finishes the setting of the new train schedule.

In the case where the above-mentioned prepared train schedule is modified to cause a new crossing between stations, if the same processing as described above is performed to eliminate the new crossing between stations, a plurality of prepared train schedules will be generated. Since it is necessary to perform separation processing one after another between the processing, there is a possibility that the processing will be amplified in an avalanche phenomenon. Therefore, in such a case, by the process in step S9, the creation of the new train diamond is stopped, and the arrival time and departure time of the already created train diamond at each station are restored to the state before the new train diamond was created. Then, the timetable edit screen 6 is returned to the original display state and the process is completed.

With the above-described processing, the creation of one new train schedule is completed, and the train schedule that has been automatically connected and disconnected in the single track section is set. Therefore, by repeating the above process, it is possible to set an arbitrary number of train diamonds.

In the above embodiment, five stations from the first station to the fifth station are installed, and the train schedule is set for a single-track line in which the second station and the third station are connectable stations. Although an example has been described, it is possible to set the total number of stations and the releasable stations to any number.

In the above embodiment, the starting station, the starting time, the destination station, etc. are designated by the mouse pick.
Of course, other means can be used.

Furthermore, in the above embodiment, the upstream train diamond is set first and then the downstream train diamond is set, but the same effect can be obtained even if the reverse is set.

Further, in the above embodiment, the basic stop time data is included in the stop time due to the separation, but the same effect can be obtained even if separated, and the time interval data such as the departure time interval and the arrival time interval are considered. The same effect can be achieved even with the train schedules at the arrival and departure times set at each station.

Further, in the above embodiment, the arrival time and the departure time of the train schedule at all stations are first obtained, and then the crossing between the stations is detected and processed. For example, the arrival time and the departure time at each station are You may make it detect and process the cross between stations at the time of being calculated | required.

As described above in detail, according to the present invention, a train schedule for a single-track section including a connecting / disconnecting process is automatically created according to an instruction from an operator while avoiding crossing between stations.
