DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation schedule creation support system and, more particularly, to a method for drawing a stop state (stop line) at a stop station.

[0002]

2. Description of the Related Art Generally, a train operation plan includes a train operation chart in which a straight line called a line indicating a train operation is drawn on paper,
That is, it is performed by creating a train schedule. However, there are some difficulties in expressing train diagrams in a computer system, because train diagram creation has relied on the experience of its experts for many years and the train diagrams themselves are of complex nature. There's a problem. One of them is a drawing method of a stop streak indicating a stop state at a station.In general, a stop streak is displayed for reasons such as appearance and customs.
Often not drawn at all stops but only at some major stations. Fig. 4 shows, for example, the 26th National Symposium on the Use of Cybernetics in Railways (Feb. 1990, p.
319) is an example of a train schedule displayed by the drawing method adopted by the automatic diagram creation system shown in 319). In the figure, ordinates A to E are stations, stations A and E are main stations, other stations are general stations, and a horizontal axis shows time. In this example, the train is operating in the direction of A → E. 1 is a train line when the stop line at the general station is omitted and drawn only at the main station, and 2 is a train line when the arrival time and departure time at each station of the train are followed. In this example, all the train lines are used. It is stopped at. Reference numeral 3 denotes a stop line, which is represented by a line parallel to the horizontal axis at the station. Reference numeral 4 denotes a required time from departure from station A to arrival at station E. Each travel time between stations AB, BC, CD, and DE, and stops at stations B, C, and D. Calculated as the sum of hours and minutes.

Next, the operation will be described. When drawing a train line for a single train, stop lines are not drawn at general stations, so the main stations are represented by one line segment. FIG.
In the example of the above, since the stations B to D are general stations, the arrival time of the main station E is calculated from the departure time of the main station A and the required time 4 between the main stations AE to indicate the departure time of the station A. And a point indicating the arrival time at station E by a straight line. At main stations, stop lines are drawn based on the stop time at each station. This allows
The train line 1 shown in FIG. 4 is created.

[0004]

In the drawing method of the stop line used in the conventional timetable automatic creation system, the stop line is always drawn only at the station determined in advance as the main station regardless of the type of train. For example, there is a problem in that it is impossible to draw a stop line for a limited express train at a specific station and draw a stop line for an express train.

The present invention has been made in order to solve the above-described problems, and a diagram creation support system which allows an operator to select drawing / non-drawing of a stop line at an arbitrary station for an arbitrary train. The purpose is to obtain.

【Example】

Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a part for determining drawing / non-drawing of a stop line in the diagram creation support system according to the present invention. In the figure, reference numeral 5 denotes an input device such as a mouse and a keyboard for setting stop line status information;
Is an input interface for bridging data between the input device 5 and a computer 10 such as an EWS (engineering workstation); 7 is a deciding means for determining drawing / non-drawing of a stop line; 8 is a connection between the computer 10 and the output device 9 In the output interface for bridging, the output device 9 is a graphic display, a plotter printer, or the like that outputs a train line including a stop line. FIG. 2 is an example of a diamond streak including a drawing of a stop streak output by the apparatus of the present invention. In the drawing, reference numerals 2 and 3 are the same as those of the conventional device shown in FIG. Reference numeral 11 denotes stop line status information which is a part of the train information, and can be set from the input device 5 to any station of any train. In the example of this train, drawing is performed at stations A, D, and E, and non-drawing is performed at stations B and C. Reference numeral 12 denotes a train line reflecting the stop line state information. The stop line is drawn only at the stations A, D, and E, and is connected by a straight line from the departure time 13 of the station A to the arrival time 14 of the station D.

Next, means 7 for determining drawing / non-drawing of a stop line
The operation determined by the above will be described with reference to the flowchart of FIG. First, the process is started by substituting the starting station of the target train into the K station to be processed (S1). Next, if the K station is the starting station (YES in S2), the starting station is set to the K station and the starting time is set to the departure time at the K station as the starting coordinates of one line of the train diagram to be drawn (S3). In order to search for the end point coordinates of one line of the train diagram for the start point coordinates, the K station is shifted to the next station based on the traveling direction (S4), and it is determined whether the K station is the destination station of the train. A judgment is made (S5). If the destination station (YES in S5),
As the end point coordinates, the end point station is set to the K station, the end point time is set to the arrival time at the K station (S6), the start point coordinates and the end point coordinates are connected by a straight line (S7), and the process is terminated.

If the K station is not the destination station (NO at S5), stop line information at the K station is obtained (S8).
If it is "drawing", the K-point is set as the end point coordinate and connected with the start point coordinate by a straight line (S9-S10), and the process returns to S2. If the stop line status information at K station is “non-drawing”,
The K station is shifted to the next station (S11), and the process returns to S5. If K station to be searched is not the starting station as the starting point coordinates of one line of the train diagram (NO in S2), stop line status information at K station is acquired (S12), and if it is "drawing" The process moves to S3 with K station as the starting point coordinates. If it is "non-drawing", the station K is shifted to the next station to search for the start point coordinates (S13), and the process returns to S2. Note that the arrival time at each station is calculated in advance from the train type in the train information and the travel time between stations in the train operation data. With the above operation, it is possible to set the drawing / non-drawing of the stop line at an arbitrary station for an arbitrary train.

Embodiment 2 FIG. In the first embodiment, the method of determining the drawing / non-drawing of the stop streak in the order from the starting station to the destination station based on the traveling direction of the train has been described. However, the destination is determined based on the reverse direction of the traveling direction of the train. Even if the drawing / non-drawing of the stop line is determined in the order from the station to the first station,
There is a similar effect.
