Abstract

PROBLEM TO BE SOLVED: To easily prepare a train operation curve for passing a train through a specified speed point at a specified speed, such as a speed limit zone. SOLUTION: By directing a preparing direction of a first speed curve 12 to a computer by a mouse, the computer prepares the first speed curve 12 in a direction from a departure station stop point 6 to an arrival station stop point 7. By directing to the computer by the mouse, the specified speed point 10a for passing the train at the specified speed and the preparing direction of a second speed curve 13 to be prepared from the specified speed point 10a and entering the specified speed, the computer prepares the second speed curve 13 in the direction from the specified speed point 10a to the departure station stop point 6. The second speed curve 13 can thus be crossed with the first speed curve 12.

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 operating curve required for planning a train schedule.

[0002]

2. Description of the Related Art FIGS. 5 (a) and 5 (b) show, for example,
It is explanatory drawing which shows the conventional train operation curve creation method described in -207771 gazette. In FIG. 5A, for example, "power running" is selected with the mouse from the control operation selection menu shown in FIG. Next, as shown in FIG.
For example, a departure station stop point 1 displayed on an RT (graphic display) screen is designated as a control start point. According to the selected control operation “powering” and the designated control start point, the computer (not shown) performs a speed curve from the departure station stop point 1 to the speed limit 2 in the train traveling direction as shown in FIG. 3 is created automatically. Then, as shown in FIG. 7, when the speed curve 3 from the departure station stop point 1 to the arrival station stop point 4 is a continuous curve, the required time when the train operates between both stations 1 and 4 is calculated. A computer (not shown) automatically creates the represented time curve 5. In addition, the operation state of the train as shown in FIG. 9 can be collectively input by the running mode edit box shown in FIG.

[0003]

Since the conventional method of creating a train operation curve is performed as described above, the departure station stop point 1 or the specific speed point is used as the control start point, and the arrival station stop point 4 or the specific speed point is used. Since the point is set as the control end point, when a speed limit section is set between the control start point and the control end point, there is a problem that it takes time to create an operation curve passing through the speed limit. . The present invention has been made in order to solve the above problems, and a train operation curve creating method capable of easily creating a train operation curve passing a specific speed point at a specific speed such as a speed limit section. The purpose is to provide.

[0004]

According to the method for creating a train operation curve according to the present invention, information of control operations such as powering, coasting, and braking of train operation is input from a mouse to the computer, so that the computer can stop at the departure station stop point. In the train driving curve creation method in which a traveling direction from the arrival station stop point to the traveling direction to the arrival station stop point or from the arrival station stop point to the departure station stop point is created, the computer uses a mouse to generate the first speed curve. By instructing the creation direction, the computer creates a first speed curve in a direction from the departure station stop point to the arrival station stop point, and creates a second speed curve from a specific speed point and a specific speed point at which the train passes at a specific speed. Instructs the computer to create the speed curve of the vehicle with a mouse, and inputs a specific speed, whereby the computer generates a second speed curve in the direction from the specific speed point to the departure station stop point, and the second speed curve It is obtained so as to intersect the first of the rate curve.

[0005] Further, a third speed curve and a second speed curve created in the direction from the specific speed point to the arrival station stop point are continuous. In addition, by inputting information on control operations such as powering, coasting, braking, etc. of the train operation input in the driving mode edit box to the computer, the computer moves from the departure station stop point to the arrival station stop point or arrives. In the train operation curve creation method in which a speed curve in a reverse direction from a station stop point to a departure station stop point is created, a specific speed point at which a train passes at a specific speed, a specific speed, and a creation direction of the speed curve are set in a traveling mode. Input to the calculator in the edit box, the calculator creates a first speed curve in the direction from the departure station stop point to the arrival station stop point, and further generates a first speed curve from the specific speed point to the departure station stop point. A second speed curve that intersects is created. Further, a target kilometer is input in the travel mode edit box.

Speed). Next, the operation will be described. The operator can use the control operation selection menu shown in FIG.
When "power running" is selected as a control operation using a mouse,
The departure station stop point 6 is designated as the control start point in.
Then, by clicking on the right side of the departure station stop point 6 on the screen of the CRT shown in FIG. Is created in the traveling direction of the train. Next, "coasting" is designated from the control start point 8, and when the mouse is clicked on the right side of the control start point 8 as the creation direction, a speed curve 11b based on "coasting" is created. The first speed curve 12 is constituted by the speed curve 11a and the speed curve 11b. Next, "Limit braking" is specified from the specific speed at the specific speed point 10a where the speed limit section 10 starts, and the mouse is clicked on the left side of the specific speed point 10a as the creation direction, and the second speed due to "Limit braking" is generated. A curve 13 is created by equation (1) in a direction opposite to the traveling direction of the train.

[0007]

(Equation 1)

The second speed curve 13 is the speed curve 1
The creation is stopped at the intersection with 1b. Subsequently, "coasting" is specified from the specific speed at the specific speed point 10a, and the mouse is clicked on the right side of the specific speed point 10a as the creation direction, and the third speed curve 14 due to "coasting" is generated.
Is formed so as to be continuous with the second speed curve 13. Furthermore, when "braking" is designated from the control start point 9 and the mouse is clicked on the right side of the control start point 9 as a creation direction,
A fourth speed curve 15 due to “braking” is created in the traveling direction of the train up to the arrival station stop point 7. As described above, by instructing the direction in which the speed curve is created by using the mouse, the first station created from the departure station stop point 6 to the arrival station stop point 7 is created.
And the second speed curve 13 created in the direction from the specific speed point 10a to the departure station stop point 6 intersects with each other, so that a driving curve passing through the specific speed point 10a at a specific speed is created. Time can be shortened. Furthermore, since the third speed curve 14 and the second speed curve 13 created in the direction from the specific speed point 10a to the arrival station stop point 7 are continuous, an operation curve can be efficiently created. .
