Abstract

PROBLEM TO BE SOLVED: To enable a change in an operation curve by designating a new operation manipulation.SOLUTION: When reverse look up operation designation in which a position, a velocity and an operation manipulation (an operation method and a notch) are designated is performed on a basic operation curve, the basic operation curve is changed so that a train passes the designated position with the designated velocity and by the designated operation manipulation. In other words, according to the reverse look up operation designation, a reverse look up curve 11 is created as if it extends in a direction opposite to a traveling direction (in a direction toward a departure station) from a designated coordinate point 10 corresponding to the designated position L1 and the designated velocity V1 so as to reach the designated coordinate point 10 by traveling by the designated operation manipulation, and the operation curve is updated, from an intersection point 12 where the operation curve and the reverse look up curve 11 crosses each other to the designated position L1, according to the intersected reverse look up curve 11.

Description

  The present invention relates to a program for causing a computer to create an operation curve.

  Conventionally, an operation curve is created in order to create an efficient train operation plan. Devices that create this operation curve using a computer are known. The driving curve created by the conventional driving curve creating device is created so that the travel time is the shortest within the range of the train capacity while keeping the speed limit. In recent years, an operation curve creation device having a function of manually correcting a created operation curve by a user is also known (see, for example, Patent Document 1).

JP2012-192825A

  The operation curve correction function in Patent Document 1 described above, when a section (range) and a driving method on the driving curve are specified, corrects the specified section to travel with the specified driving method. This is a technique that can be called “operation designation”. That is, it can be said to be a forward designation of how to drive a certain position. With this correction function, for example, it is difficult to respond to a request such as “I want to correct an operation curve that passes a certain position at a certain speed”. If such a request is to be satisfied by the forward driving specification, it is necessary to repeat the specification of the section and the driving method and adjust until the driving curve to be corrected passes the position at the speed.・ I had to do an error.

  The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to realize a new method for changing an operation curve such as “passing a certain position at a certain speed”.

The first invention for solving the above-described problems is

At least 1) invalidity judging means for judging that the set passage condition is invalid when the given operation curve and the reverse curve do not intersect;
An operation curve changing means for changing the given operation curve so as to pass through the designated coordinate point along the reverse curve according to a passing condition that has not been determined to be invalid by the invalidity determining means;
As a program for causing the computer to function.

As another invention,
Passage condition setting means for setting a passage condition for passing a designated position at a designated speed and a designated driving operation for a given driving curve created on a two-axis coordinate system of a running position and a running speed;

You may comprise the operating curve preparation apparatus provided with.

  According to the first invention and the like, a reverse curve according to the specified driving operation is generated from the specified coordinate point on the coordinate system specified by the specified position and the specified speed, and along the generated reverse curve A given driving curve is changed to pass a designated coordinate point. Therefore, when the passing condition for passing the designated position at the designated speed and the designated driving operation is set with respect to the driving curve, the driving curve is changed so as to pass the designated position at the designated speed and the designated driving operation. A new method of changing the operating curve is possible. When the given operation curve and the reverse curve do not intersect, the passage condition is determined to be invalid and the operation curve is not changed. For this reason, it is possible to accurately determine the case where the passage condition is invalid.

As a second invention, there is provided a program according to the first invention,
The passing condition setting means sets the operation method of powering / running / brake and the designation of the notch in the case of powering or braking as the specified operation.
The reverse curve creating means creates the reverse curve by extending the speed curve in the reverse direction from the designated coordinate point when the designated driving operation is continued and reaches the designated coordinate point.
A program may be configured.

  According to the second aspect of the present invention, it is possible to set powering / running / brake driving methods and notch specification for powering / braking as designated driving operations. Since the reverse curve is created by extending the speed curve in the reverse direction from the specified coordinate point when the specified operation is continued to reach the specified coordinate point, the operation curve that satisfies the passing condition is created. Changes can be implemented efficiently.

A third invention is a program according to the first or second invention,
The given operation curve is created so as to satisfy a predetermined speed constraint condition,
In the case of 1), the invalidity determining means is 2) when the specified coordinate point does not satisfy the speed constraint condition, and 3) the specified position of the specified coordinate point is a stop brake of the given driving curve. If the specified coordinate point is within the travel range of the curve portion and the specified speed of the specified coordinate point is higher than that of the stop brake curve portion, 4) the specified position of the specified coordinate point of the given driving curve is When it falls within the travel range of the immediately preceding brake curve portion of the speed restriction location included in the speed constraint condition and the specified speed at the specified coordinate point is higher than the immediately preceding brake curve portion, , Determining that the set passage condition is invalid.
A program may be configured.

  According to the third aspect of the present invention, it is possible to accurately determine when the passage condition is invalid.

[Overview]
The driving curve creation device of the present embodiment has a function of changing a given driving curve in accordance with an instruction operation by a user.

(A) Driving curve The driving curve is created in units of stations as shown in FIG. 1, for example, on the coordinate system with the horizontal axis representing the travel position (distance expressed in kilometres) and the vertical axis representing the travel speed. Is expressed as a graph showing the speed change with respect to the train position. In addition, the driving curve is created so that the train performance is maximized while maintaining the specified speed limit (that is, the maximum notch is used for both power running and braking) and the train runs between stations in the shortest time. It is common. In the example shown in FIG. 1, “5 notch”, which is the maximum notch, is used for both power running and braking. As described above, “a method of creating an operation curve that travels while maximizing the train performance while maintaining a predetermined speed limit” is particularly referred to as a “basic creation method” in the present embodiment.

(B) Reverse pulling operation designation In this embodiment, reverse pulling operation designation can be performed as an instruction to change the operation curve. In reverse pulling operation designation, if “position, speed, and driving operation (driving method (power running / running / braking) and notch)” are designated, the designated position is passed at the designated speed and designated driving operation based on this. Thus, the driving curve is updated.

  FIG. 2 is an example of updating the operation curve by specifying reverse pulling operation. FIG. 2A shows an example of the reverse operation specification for the operation curve, and FIG. 2B shows the operation curve after the change based on the reverse operation specification. That is, as shown in FIG. 2A, the position “L1”, the speed “V1”, and the driving operation “three-notch brake” are specified as the reverse pulling operation specification for the driving curve. Then, as shown in FIG. 2B, based on this reverse pulling operation designation, the running curve is changed so that the designated position L1 is passed by the 3-notch brake which is the designated driving operation at the designated speed V1. The

  Specifically, the operation curve is changed based on the reverse pulling operation designation as follows. First, in order to pass the designated coordinate point 10 corresponding to the designated position “L1” and the designated speed “V1” with the “three-notch brake” that is the designated operation operation, the direction of travel (from the designated direction) The reverse curve 11 extended in the direction toward the station) is generated. Next, an intersection 12 between the operation curve and the reverse curve 11 is obtained, and the operation curve is updated so that the vehicle travels along the reverse curve 11 in a section from the intersection 12 to the designated position “L1”. Subsequently, for the section after the designated position “L1”, the driving curve is updated by the basic creation method.

(C) Generation of Reverse Lookup Curve Creation of the reverse draw curve will be described in detail.

(C-1) Speed condition When the designated speed specified for reverse pulling operation does not satisfy the predetermined speed condition, the reverse pulling operation designation is invalid, and the corresponding reverse pulling curve is not created.

  FIG. 3 is an example of reverse pulling operation designation that does not satisfy the speed condition. That is, the speed conditions are: (a) The specified speed does not exceed the maximum speed between stations, (b) The specified speed does not exceed the limit speed when the specified position is within the speed limit section, (c) The specified position The specified speed is not faster than the brake curve when is within the travel section of the brake curve. If any one of these conditions (a) to (c) is not satisfied, the speed condition is not satisfied and the reverse operation designation is invalid (it can be said that it is invalid in that it does not work effectively). Judge and do not create a corresponding reverse curve. It can also be said that the conditions (a) and (b) satisfy the speed constraint condition.

  The brake curve in (c) includes both a stop brake curve and a speed limit brake curve. The stop brake curve is a brake curve for stopping at the arrival station, and the speed limit brake is a brake curve for decelerating to the limit speed immediately before the speed limit section.

(C-2) Generation range A reverse curve is generated from a specified position and a specified speed so as to extend in a direction opposite to the traveling direction (direction toward the departure station) by a specified driving operation. When the censoring condition is satisfied, generation of the reverse curve is terminated.

  FIG. 4 is a diagram for explaining a reverse curve generation range. That is, the censoring condition is (d) when the speed reaches 0 (zero), (e) when the position is within the speed limit section, the speed reaches the speed limit, and (f) the speed is between stations. The maximum speed has been reached, (ki) position has reached the travel start position (departure station). When any one of these conditions (d) to (g) is satisfied, the generation of the reverse curve is terminated assuming that the termination condition is satisfied. When the reverse curve created under the truncation conditions (D) to (G) does not intersect with the operation curve (when it does not intersect with the updated operation curve for each of the multiple reverse operation designations described later) The reverse curve is invalid.

(D) Application of reverse pulling operation designation (d-1) Multiple reverse pulling operation designations A plurality of reverse pulling operation designations can be applied to one operation curve. In this case, as shown in FIG. 5, a reverse curve corresponding to each of the plurality of reverse pulling operation designations is generated, and in the order of crossing when traveling along the driving curve from the travel start position (departure station), The driving curve is updated according to the crossed reverse pulling curve. That is, first, the reverse curve that first intersects with the operation curve is applied to update the operation curve, and then the reverse curve that first intersects the operation curve after the designated position of the applied reverse curve similarly. The process of updating by applying a curve is repeated until the vehicle arrives at the travel end position (arrival station).

  In the example shown in FIG. 5, two reverse driving operations of position “L2”, speed “V2”, driving operation “3-notch brake”, position “L3”, speed “V3”, and driving operation “coasting” are performed. Designations (A) and (B) are made. Then, two reverse pulling curves 11a and 11b corresponding to the two reverse pulling operation designations (A) and (B) are generated. In this case, first, the reverse curve 11b that first intersects the driving curve is applied to update the driving curve to the designated position L3, and the section after the designated position L3 is updated by the basic creation method. Subsequently, among the updated operating curves, the operating curves after the designated position L3 are not updated because they do not intersect with the reverse curve 11a. That is, in the example of FIG. 5, the reverse operation specification (A) is invalid, and the operation curve is updated by applying only the reverse operation specification (B).

[Function configuration]
FIG. 6 is a functional configuration diagram of the operation curve creation device 1. As shown in FIG. 6, the driving curve creation device 1 includes an operation unit 110, a display unit 120, a communication unit 130, a processing unit 200, and a storage unit 300.

  The operation unit 110 is an input device including, for example, a keyboard, a mouse, a touch panel, various switches, and the like, and outputs an operation signal according to a user operation input to the processing unit 200. The display unit 120 is a display device configured by, for example, a liquid crystal display (LCD) or an organic EL display, and performs various displays based on display signals from the processing unit 200. The communication unit 130 is a communication device including, for example, a wireless communication module, a router, a modem, a wired communication cable jack, and a control circuit, and performs data communication with an external device.

  The processing unit 200 is configured by an arithmetic device such as a CPU, for example. The processing unit 200 performs various arithmetic processing based on programs and data stored in the storage unit 300, input data from the operation unit 110, and the like, and the operation curve generating device 1 Sends instructions and data transfer to each component. The processing unit 200 includes a basic operation curve creation unit 210, an operation designation setting unit 220, a reverse curve generation unit 230, and an operation curve change unit 240, and an operation curve according to the operation curve creation program 310. A creation process (see FIG. 8) is performed.

  The basic operation curve creation unit 210 creates an operation curve (basic operation curve) for traveling between target stations in the shortest travel time by a basic creation method based on the track conditions and train conditions. The track condition is a track condition such as track length, gradient, curvature, maximum speed between stations, and speed limit section, and is stored as track condition data 320. The vehicle condition is a condition related to the performance of the train such as assumed acceleration, maximum speed, deceleration, and weight of the train, and is stored as the train condition data 330. The created basic operation curve is stored as basic operation curve data 340.

  The operation designation setting unit 220 sets a reverse operation designation to be applied to the basic operation curve in accordance with a user instruction operation via the operation unit 110. The reverse pulling operation designation is a kind of condition for designating the position, speed, and driving operation (driving method and notch), and is a passing condition for passing the designated position at the designated speed and the designated driving operation. In addition, one or a plurality of reverse pulling operation designations can be set for one basic operation curve. The set reverse pulling operation designation is stored as operation designation setting data 350.

  FIG. 7 is a diagram illustrating a data configuration example of the operation designation setting data 350. According to FIG. 7, the operation designation setting data 350 associates a designation number 351 that is an identification number, a designated position 352, a designated speed 353, and a designated driving operation 354 with respect to each set reverse pulling operation designation. Storing. The designated operation 354 includes a designated operation method 354a and a designated notch 354b.

  The reverse curve generation unit 230 generates a corresponding reverse curve for each reverse operation specification set by the operation specification setting unit 220. That is, it is determined whether or not the designated speed specified for reverse pulling operation satisfies a predetermined speed condition (see FIG. 3), and when the speed condition is satisfied, a corresponding reverse pulling curve is generated. The reverse curve runs from the designated coordinate point corresponding to the designated position and the designated speed in the direction opposite to the traveling direction (direction toward the departure station) and travels in the designated driving operation to reach the designated coordinate point. It produces | generates as such an operation curve (refer FIG.2 (b)). The generation of the reverse curve is terminated when a predetermined cutoff condition is satisfied (see FIG. 4).

  The operation curve change unit 240 updates the basic operation curve created by the basic operation curve creation unit 210 based on the reverse curve generated by the reverse curve generation unit 230. That is, the basic operation curve is updated in accordance with the crossed reverse pulling curve in the order of crossing when traveling along the basic operation curve from the travel start position (departure station). That is, first, the basic operation curve is updated based on the operation curve and the reverse curve that intersects first. Subsequently, the operation curve after the designated position of the reverse curve is similarly updated by applying the reverse curve that intersected first until the travel end position (arriving station) is reached (see FIG. 5). The updated operation curve is stored as updated operation curve data 360.

  The storage unit 300 stores a system program for realizing various functions for the processing unit 200 to control the operation curve creating apparatus 1 in an integrated manner, a program and data for realizing the present embodiment, and the like. It is used as a work area of the processing unit 200 and temporarily stores calculation results executed by the processing unit 200 according to various programs, input data from the operation unit 110, and the like. In the present embodiment, an operation curve creation program 310, track condition data 320, train condition data 330, basic operation curve data 340, operation designation setting data 350, and updated operation curve data 360 are stored.

[Process flow]
FIG. 8 is a flowchart for explaining the flow of the operation curve creation process. According to FIG. 8, first, the basic operation curve creation unit 210 creates a basic operation curve (step S1). Next, the operation designation setting unit 220 sets reverse operation designation, which is a passage condition applied to the basic operation curve, in accordance with the operation designation instruction operation by the user via the operation unit 110 (step S3). Subsequently, the reverse curve generation unit 230 determines whether or not the specified speed satisfies a predetermined speed condition for each set reverse pull operation designation, and if the speed condition is satisfied (step S5: YES), the specified position Is generated at a designated speed and at a designated speed (step S7).

  Thereafter, the operation curve changing unit 240 updates the basic operation curve based on the generated reverse operation curve. That is, the first intersection of the basic operation curve and the reverse lookup curve when traveling from the travel start position (departure station) along the basic operation curve is searched (step S9). If there is an intersection (step S11: YES), the basic operation curve is updated from the intersection to the designated position along the crossed reverse pulling curve (step S13). Then, the operation curve in the section after the designated position is updated by the basic creation method (step S15). Subsequently, the first intersection of the updated operation curve and the reverse curve after the designated position is searched for from the updated basic operation curve (step S17), the process returns to step S11, and the same processing is repeated.

  If there is no intersection between the basic operation curve and the reverse curve (step S11: NO), it is determined that the basic operation curve has been updated, and the updated operation curve is displayed and output, for example (step S19). Then, the operation curve creation process ends.

[Function and effect]
As described above, according to the operation curve creation device 1 of the present embodiment, when the reverse operation operation designation that designates the position, speed, and operation operation (operation method and notch) is performed on the basic operation curve, It is possible to realize a change in the driving curve based on the designation of a new driving operation such that the basic driving curve is changed so as to pass the designated position at the designated speed and the designated driving operation. In other words, according to the reverse pulling operation specification, the specified coordinates are obtained by running in the specified driving operation so as to extend in the reverse direction of the traveling direction (direction toward the departure station) from the specified coordinate point corresponding to the specified position and the specified speed. A reverse curve that reaches the point is generated, and the operation curve is updated from the intersection of the operation curve and the reverse curve to a specified position according to the crossed reverse curve.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can of course be changed as appropriate without departing from the spirit of the present invention.

(A) Application of reverse curve In the above-described embodiment, the operation curve is updated based on the reverse curve intersecting with the operation curve. However, as an exception, even if the operation curve intersects with the reverse curve, The operation curve may not be updated based on the reverse curve. Specifically, as shown in FIG. 9, when the reverse operation curve intersects the stop brake curve or the speed limit brake curve of the operation curve, the corresponding reverse operation designation is invalid and the operation curve It is good not to update.

(B) Forward pulling operation designation In addition to the reverse pulling operation designation, the conventional forward running operation designation may be applicable to the operation curve. In the forward operation designation, a section (start position and end position) and a driving operation (driving method and notch) are designated. In this case, the reverse pulling operation designation has priority over the forward pulling operation designation. That is, first, the operation curve is updated based on the forward operation specification, and then the updated operation curve is updated based on the reverse operation specification.
