For example, Patent Document 1 discloses a device that creates a new driving curve in which traveling time is made longer than the driving curve before the change by adding coasting.

JP 2004-155314 A

  When changing the driving curve by adding coasting, that is, when changing the powering or braking included in the driving curve to coasting, select the driving curve part to be changed and temporarily change the driving curve. If the changed operating curve does not satisfy the predetermined condition, the calculation of canceling the temporary change is repeatedly executed. Therefore, as the number of operation curve portions that are candidates for change increases, the amount of calculation increases exponentially.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a new operation curve creation method with improved calculation efficiency.

The first invention for solving the above-described problems is

If the running time of the entire driving curve temporarily changed to coasting is within the predetermined allowable running time, the provisional coasting is confirmed and the driving curve is updated, and is not within the allowable running time In this case, partial curve change control means for repeatedly executing canceling the provisional coasting and selecting the new coasting candidate and causing the provisional coasting means to make a change to provisional coasting,
When the travel time of the entire driving curve that has been temporarily changed to coasting is not within the allowable travel time, the coasting candidate that satisfies the predetermined positional relationship with the provisional coasting curve portion is selected as the temporary coasting Exclusion means to exclude from the selection options of the optimization means,
As a program for causing the computer to function.

As another invention,
An operation curve creation device for changing a given operation curve and creating a new operation curve,
Temporary coasting means for selecting a coasting candidate and tentatively switching to coasting from among coasting candidates that are candidates for a curve portion that can be changed to coasting included in the driving curve;
If the running time of the entire driving curve temporarily changed to coasting is within the predetermined allowable running time, the provisional coasting is confirmed and the driving curve is updated, and is not within the allowable running time A partial curve change control means for repeatedly executing canceling the provisional coasting in the case, and selecting the new coasting candidate and causing the provisional coasting means to perform a change to the provisional coasting. ,
When the travel time of the entire driving curve that has been temporarily changed to coasting is not within the allowable travel time, the coasting candidate that satisfies the predetermined positional relationship with the provisional coasting curve portion is selected as the temporary coasting Exclusion means for excluding from the selection candidates of the optimization means,
You may comprise the operating curve preparation apparatus provided with.

  According to the first invention, etc., when the running time of the entire driving curve that is temporarily changed to coasting by selecting the coasting candidate included in the given driving curve is not within the allowable driving time, The candidates for coasting that satisfy the predetermined positional relationship with the curve portion of the provisional coast are excluded from the selection candidates to be changed to provisional coast. Thereby, the creation method of the new operation curve which improved the calculation efficiency is realizable.

As a second invention, a program of the first invention,
The provisional coasting means selects the powering curve portion (hereinafter referred to as “powering coasting candidate”) as the coasting candidate, and sets the forward coasting curve from the powering coasting candidate to thereby change the provisional change. A power running provisional coasting means for carrying out
The exclusion means includes power running coasting exclusion means for excluding from the selection candidate a power running curve portion between the selected power running coasting candidate and the brake curve portion closest to the outside.
A program may be configured.

  According to the second aspect of the invention, when the power running curve portion is selected as a coasting candidate and the running time of the entire driving curve in which the power running coasting candidate is tentatively changed to coasting is not within the predetermined allowable running time. The power running curve portion between this power running coasting candidate and the outermost brake curve is excluded from the selection candidates to be changed to temporary coasting. This is because by setting a forward coasting curve from a powering coasting candidate, the powering coasting candidate is changed to provisional coasting. That is, the forward coasting curve is set so as to extend inward of the powering coasting candidate. For this reason, when the coasting curve portion of the selected coasting candidate is coasted in the same manner, the traveling time becomes longer than coasting the selected coasting candidate.

As a third invention, a program of the first or second invention,
The provisional coasting means selects the brake curve portion (hereinafter referred to as “brake coasting candidate”) as the coasting candidate, and sets the reverse coasting curve from the brake coasting candidate to thereby change the provisional change. A brake provisional coasting means for carrying out
The exclusion means includes a brake coasting exclusion means for excluding a brake curve portion between the selected brake coasting candidate and a power running curve portion closest to the inward from the selection candidates.
A program may be configured.

  According to the third aspect of the invention, when the brake curve portion is selected as a coasting candidate and the travel time of the entire driving curve in which the brake coasting candidate is temporarily changed to coasting is not within the predetermined allowable travel time. The brake curve portion between this brake coasting candidate and the innermost power running curve portion is excluded from the selection candidates to be changed to temporary coasting. This is because the coasting of the brake coasting candidate is performed by setting a reverse curve from the brake coasting candidate. That is, the reverse coasting curve is set to extend outward from the brake coasting candidate. For this reason, when the coasting portion of the selected brake coasting candidate is coasted in the same manner, the running time becomes longer than coasting the selected brake coasting candidate.

[Overview]
The operation curve creation device of this embodiment is a device that changes a given operation curve and generates a new operation curve.

(A) Operation Curve FIG. 1 is an example of an operation curve. As shown in FIG. 1, the driving curve is generated in units between stations, and the horizontal axis represents the travel position (distance expressed in kilometres), and the vertical axis represents the travel speed, indicating the speed change with respect to the train position Is expressed as In general, the driving curve is created so that the train performance is maximized while traveling within the shortest distance between stations while maintaining a predetermined speed limit. The operation curve thus created is hereinafter referred to as “basic operation curve”. In this embodiment, the basic operation curve is changed to generate an operation curve (hereinafter referred to as “standard operation curve”) in which the travel time is close to the allowable travel time and is equal to or less than the allowable travel time. The allowable travel time is determined to be longer than the shortest travel time, which is the travel time on the basic operation curve, and is determined in consideration of a margin for train operation.

(B) Change of Driving Curve As shown in FIG. 1, the driving curve is configured by combining three types of curve portions, that is, a power running curve portion 12, a coasting curve portion 14, and a brake curve portion 16. In this embodiment, the power running curve portion 12 and the brake curve portion 16 of the basic running curve are changed to lameness (running) to generate a standard running curve.

(B-1) Coasting of power running FIG. 2 is a diagram for explaining coasting of power running. FIG. 2 shows a part of an operation curve including power running. Note that the power running subject to coasting is a power running other than the power running at the departure of the departure station (hereinafter referred to as “re-powering”).

  Powering coasting is achieved by forward coasting. That is, as shown in FIG. 2 (1), forward coasting when traveling in a coasting direction from the starting point 13a of the power running 12a toward the traveling direction of the train (direction toward the arrival station, right direction in FIG. 2). A curve 18a is generated. Then, as shown in FIG. 2 (2), a section from the starting point 13a of the power running 12a to the intersection 19a of the forward coasting curve 18a and the running curve is run along the forward coasting curve 18a. , Change the driving curve. Note that the section before the start point 13a of the power running 12a and the section after the intersection 19a are left as they are. When the forward coasting curve crosses zero speed, it is determined that coasting cannot be performed, that is, powering to be coasted cannot be coasted.

(B-2) Brake coasting FIG. 3 is a diagram illustrating the coasting of the brake. FIG. 3 shows a part of an operation curve including a brake. The brakes to be coasted are brakes other than the brakes when arriving at the arrival station (hereinafter referred to as “intermediate brakes”).

  Brake coasting is achieved by reverse coasting. That is, as shown in FIG. 3 (1), when traveling in coasting from the end point 17b of the brake 16b in the direction opposite to the traveling direction of the train (the direction toward the departure station; left direction in FIG. 3). Then, a reverse coasting curve 18b passing through the end point 17b of the brake 16b is generated. Then, as shown in FIG. 3 (2), the vehicle travels along the reverse coasting curve 18b in the section from the intersection 19b between the reverse coasting curve 18b and the driving curve to the end point 17b of the brake 16b. , Change the driving curve. Note that the section before the intersection 19b and the section after the end point 17b of the brake 16b are left as they are. When the reverse coasting curve crosses zero speed, it is determined that coasting is impossible, that is, the brake to be coasted cannot be coasted.

(C) Exclusion of coasting candidates Creation of a new driving curve is realized by selecting a plurality of coasting candidates one by one and changing them to coasting (coasting) for the basic driving curve. Yes. The coasting candidate is a candidate for a curve portion that can be changed to coasting included in the driving curve, and is a curve portion for repowering and a curve portion for halfway braking. If one coasting candidate is selected, a provisional driving curve is generated, which is a driving curve in which the selected coasting candidate is tentatively changed to coasting, and if the running time of the provisional driving curve does not exceed the allowable driving time For example, the provisional coasting is confirmed, and if the allowable running time is exceeded, the provisional coasting is canceled. This is repeated one by one for the lameness candidate.

  As a feature of the present embodiment, when the travel time of the provisional driving curve in which the coasting candidate is temporarily coasted does not satisfy the allowable travel time, the coasting candidate and another coasting condition that satisfies a predetermined positional relationship condition Exclude candidates from coasting candidates. The coasting candidates include a power running curve portion (power running coasting candidate) and a brake curve portion (brake coasting candidate). Each case will be described.

(C-1) Exclusion of Power Running Coaching Candidate FIG. 4 is a diagram for explaining exclusion of a power running lame candidate. FIG. 4 shows a part of an operation curve including a plurality of power runnings. As shown in FIG. 4 (1), this driving curve includes four repowering 12c to 12f, and the coasting and repowering 12d to 12f repeat between the brake 16c and the brake 16d. It has become. The repowering 12c to 12f are coasting candidates (powering coasting candidates).

  When the running time of the provisional driving curve in which a certain power running coasting candidate is coasted with respect to such a driving curve exceeds the allowable running time, the coasting of the power running coasting candidate is canceled (cancelled). In such a case, as a positional relationship condition with this powering coasting candidate, the powering coasting candidate between the outermost (the direction opposite to the traveling direction, leftward in FIG. 4) to the nearest brake curve portion is Excluded from candidates for lameness. That is, as shown in FIG. 4 (2), when the running time of the provisional driving curve in which the third power running coasting candidate 12e counted in the traveling direction exceeds the allowable running time, this power running coasting is performed. While the coasting of the candidate 12e is canceled, the powering coasting candidate 12d between the powering coasting candidate 12e and the brake 16c closest to the outside is excluded from the coasting candidates.

  This is because coasting of power running is performed by forward coasting. That is, in forward coasting, a forward coasting curve extending in the forward direction (traveling direction, rightward in FIG. 4) is generated from the powering start point of the powering coasting candidate, and the forward coasting curve and the driving curve are generated. The driving curve is changed to coasting for a section up to the intersection with the innermost braking curve portion. Therefore, for the power running between the power running coasting candidate and the most recent brake curve portion, when the power running is coasted, all the braking curves intersecting the forward coasting curves are the same, Alternatively, the forward coasting curve crosses zero speed. That is, in the case of coasting, the running time of the driving curve becomes longer. Therefore, when canceling the coasting of a powering coasting candidate, the powering coasting candidate that satisfies the predetermined positional relationship with the powering coasting candidate does not satisfy the coasting condition (condition that is equal to or less than the allowable travel time). Therefore, it is excluded from lameness candidates. Thereby, the subsequent calculation amount related to the creation of the operation curve is reduced.

(C-2) Exclusion of Brake Coasting Candidate FIG. 5 is a diagram for explaining exclusion of a brake coasting candidate. FIG. 5 shows a part of an operation curve including a plurality of halfway brakes. As shown in FIG. 5 (1), this driving curve includes five halfway brakes 16g to 16k, and a downward slope is formed between the halfway brake 16g and the halfway brake 16j. The coasting and the brakes 16g to 16j are repeated. The brakes 16g to 16k are coasting candidates (brake coasting candidates).

  If the running time of the provisional driving curve in which a certain brake coasting candidate is coasted with respect to such a driving curve exceeds the allowable traveling time, the coasting of the brake coasting candidate is canceled. In such a case, as a positional relationship condition with this brake coasting candidate, a brake coasting candidate between the inner power (traveling direction; rightward in FIG. 5) and the nearest power coasting is excluded from the coasting candidate. Is done. That is, as shown in FIG. 5 (2), when the running time of the provisional driving curve obtained by coasting the first brake coasting candidate 16g counted in the traveling direction exceeds the allowable traveling time, this brake coasting is performed. While the coasting of the candidate 16g is canceled, the brake coasting candidates 16h to 16j from the brake coasting candidate 16g to the innermost power running 12i are excluded from the coasting candidates.

  This is because the brake coasting is performed by reverse coasting. In other words, in reverse coasting, a reverse coasting curve extending in the direction opposite to the traveling direction is generated from the coasting end point of the brake coasting candidate, and the intersection of the reverse coasting curve and the driving curve, that is, the nearest outward direction. For the section up to the intersection with the power running curve, change the running curve to coasting. For this reason, with regard to the brake between the inward nearest power running curve portion of this brake coasting candidate, if the brake is coasted, are all the power running curve portions where the reverse coasting curves intersect are the same? Or, the reverse coasting curve crosses zero speed. That is, in the case of coasting, the running time of the driving curve becomes longer. Therefore, when canceling the coasting of the brake coasting candidate, the brake coasting candidate that satisfies the predetermined positional relationship condition with the brake coasting candidate does not satisfy the coastable condition (condition that is equal to or less than the allowable travel time). Therefore, it is excluded from lameness candidates. Thereby, the subsequent calculation amount related to the creation of the operation curve is reduced.

[Function configuration]
FIG. 6 is a functional configuration diagram of the operation curve creation device 1. According to FIG. 6, the driving curve creation device 1 is a type configured to include an operation unit 110, a display unit 120, a sound output unit 130, a communication unit 140, a processing unit 200, and a storage unit 300.

The sound output unit 130 is a sound output device configured by, for example, a speaker and performs various sound outputs based on the sound signal from the processing unit 200. The communication unit 140 is a communication device including, for example, a wireless communication module, a router, a modem, a wired communication cable jack, a control circuit, and the like, and performs data communication with an external device.

  The processing unit 200 is configured by an arithmetic device such as a CPU, for example, and performs various arithmetic processing based on programs and data stored in the storage unit, input data from the operation unit 110, and the like, and also configures the operation curve generating device 1. Instructions and data transfer to each unit. Further, the processing unit 200 includes a midway brake coasting unit 210, a brake curve part change control unit 220, a midway brake candidate exclusion unit 230, a repowering coasting unit 240, a powering curve part change control unit 250, A power running candidate exclusion unit 260, and performs a running curve creation process (see FIG. 7) according to the running curve creation program 310.

  The mid-brake coasting unit 210 generates a provisional driving curve in which the braking coasting candidate is temporarily changed to coasting (cooked) with respect to the driving curve. That is, a reverse coasting curve is set from the brake end point of the brake coasting candidate, and the section from the brake end point to the intersection of the reverse coasting curve and the driving curve is changed to coasting along the reverse coasting curve. (See FIG. 3).

  The brake curve portion change control unit 220 controls the change of the brake curve portion with respect to the driving curve. In other words, a brake curve portion on the way to be a coasting candidate is extracted from the driving curve and set as a brake coasting candidate. Then, each of the brake coasting candidates is generated in a predetermined order (for example, in order of decreasing brake time) by causing the intermediate brake coasting unit 210 to generate a provisional driving curve that coasts the brake coasting candidate, and the provisional generated If the running time on the driving curve does not exceed the allowable running time, confirm the coasting of the relevant brake coasting candidate, and if the running time exceeds the allowable running time, Repeat canceling lameness.

  The midway brake candidate exclusion unit 230, when the running time of the provisional driving curve generated by the midway brake coasting unit 210 exceeds the running time, the power running curve closest to the inside of the coasted brake coasting candidate. The brake on the way to the part is excluded from the coasting candidates (see FIG. 5).

  The repowering coasting unit 240 generates a provisional driving curve in which the powering coasting candidate is temporarily changed to coasting (running) for the driving curve. In other words, a forward coasting curve is set from the powering start point of the powering coasting candidate, and the section from the powering start point to the intersection of this forward coasting curve and the operating curve is changed to coasting along the forward coasting curve. (See FIG. 2).

  The power running curve portion change control unit 250 controls the change of the power running curve portion with respect to the operation curve. That is, a re-powering curve portion that is a coasting candidate is extracted from the driving curve and is set as a powering coasting candidate. Then, each of the powering coasting candidates is generated in a predetermined order (for example, in order of short powering time) by causing the repowering coasting unit 240 to generate a provisional driving curve that coasts the powering coasting candidate. If the running time on the driving curve does not exceed the allowable running time, confirm the coasting of the power running coasting candidate, and if the running time exceeds the allowable running time, the power running coasting candidate Repeat canceling lameness.

  When the running time of the provisional driving curve generated by the re-powering coasting unit 240 exceeds the allowable traveling time, the re-powering candidate exclusion unit 260 generates the braking curve closest to the outside of the coasting candidate that has been coasted. The repowering between the parts is excluded from the lameness candidates (see FIG. 4).

  The storage unit 300 stores a system program for realizing various functions for the processing unit 200 to control the operation curve creation device 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, the storage unit 300 stores the driving curve creation program 310, the basic driving curve data 320, the standard driving curve data 330, the allowable travel time data 340, the brake coasting candidate data 350, and the power running coasting. Candidate data 360 is stored.

  The basic operation curve data 320 is basic operation curve data to be changed. The standard operation curve data 330 is operation curve data generated by changing the basic operation curve. The permissible travel time data 340 is data for permissible travel time that is a criterion for determining / cancelling coasting candidates for coasting candidates with respect to the basic operation curve. Depending on the track environment (number of railroad crossings, tunnels, etc.) and the speed limit.

  The brake coasting candidate data 350 is data of the brake coasting candidate extracted from the basic driving curve by the brake curve partial change control unit 220. These brake coasting candidates can be excluded from coasting candidates by the midway brake candidate excluding unit 230. Powering coasting candidate data 360 is data of powering coasting candidates extracted from the basic driving curve by the power running curve partial change control unit 250. These power running candidates can be excluded from the coasting candidates by the repowering candidate exclusion unit 260.

[Process flow]
FIG. 7 is a flowchart for explaining the running curve creation process. This process is realized by the processing unit 200 executing the operation curve creation program 310.

  According to FIG. 7, the processing unit 200 first acquires an operation curve to be changed (step A1). Next, an allowable travel time for the operation curve acquired as a change target is set (step A3). Here, the operation curve to be changed may be a basic operation curve or another operation curve, and can be acquired by external input.

  Thereafter, a midway brake coasting process (see FIG. 8) is performed, and the running curve is changed by coasting the midway brake curve portion (step A5). When the mid-brake coasting process is completed, the re-running coasting process (see FIG. 9) is performed, and the driving curve is changed by coasting the re-powering curve part (step A7). When the repowering coasting process ends, the changed operation curve is displayed and output on the display unit 120, for example, as a newly created operation curve (standard operation curve) (step A9). If the above process is performed, a driving | running curve preparation process will be complete | finished.

  FIG. 8 is a flowchart for explaining the midway brake coasting process. According to FIG. 8, the brake curve portion change control unit 220 extracts all halfway brake curve portions from the driving curve as coasting candidates (step B1). Next, the extracted coasting candidates are processed in a loop A in which the brake targets are processed in ascending order.

  In loop A, the target brake coasting candidate is coasted by reverse coasting to generate a provisional driving curve in which the driving curve is changed (step B3). Next, the travel time of the generated provisional operation curve is calculated (step B5). If the travel time of the calculated provisional operation curve is equal to or less than the allowable travel time (step B7: YES), provisional coasting is confirmed, The provisional operation curve is changed to a new operation curve (step B9). Then, it returns to step B3 and performs the same process for the next brake coasting candidate.

  On the other hand, if the running time of the provisional driving curve exceeds the allowable running time (step B7: NO), the provisional coasting of the target brake coasting candidate is canceled (step B11), and the intermediate brake candidate excluding unit 230 is After excluding from the coasting candidate the intermediate brake between the target brake coasting candidate and the inward nearest power running curve portion (step B13), the loop A is terminated. When the process of Loop A is completed, the brake coasting process is terminated.

  FIG. 9 is a flowchart for explaining the re-running coasting process. According to FIG. 9, the power running curve portion change control unit 250 extracts all re-power running curve portions from the running curve as candidates for coasting (step C1). Next, a process of loop B is performed on each of the extracted power running candidates as a processing target in order of shorter power running time.

  In loop B, the target powering coasting candidate is coasted by forward coasting to generate a provisional driving curve in which the driving curve is changed (step C3). Next, the travel time of the generated provisional driving curve is calculated (step C5). If the calculated travel time of the provisional driving curve is equal to or less than the allowable travel time (step C7: YES), provisional coasting is confirmed. The provisional operation curve is changed to a new operation curve (step C9). Thereafter, the process returns to step C3, and the same processing is performed for the next candidate for the power running / launching.

  On the other hand, if the running time of the provisional driving curve exceeds the allowable running time (step C7: NO), the provisional coasting of the target powering coasting candidate is canceled (step C11), and the repowering candidate exclusion unit 260 Then, after the repowering from the target powering coasting candidate to the brake curve portion closest to the outside is excluded from the coasting candidates (step C13), the loop B is terminated. When the process of loop B is finished, the repowering coasting process is finished.

[Function and effect]
According to the driving curve creation device 1 of the present embodiment, for each coasting candidate included in the driving curve, a temporary driving curve in which the coasting candidate is temporarily changed to coasting is generated, and the travel time of the temporary driving curve is determined. If the allowable running time is not exceeded, the provisional coasting is determined, and if the allowable traveling time is exceeded, the temporary coasting is canceled to create a new operation curve. In addition, when the running time of the provisional driving curve in which the coasting candidate is temporarily coasted does not satisfy the allowable travel time, another coasting candidate that satisfies the predetermined position relation condition with the coasting candidate, Exclude from lameness candidates.

  That is, when a power coasting candidate is provisionally coasted, the power coasting candidate from the power running candidate to the outermost brake curve portion is excluded from the coasting candidate, and the brake coasting candidate Is temporarily laid down, the brake coasting candidates between the brake coasting candidate and the inward nearest power running curve portion are excluded from the coasting candidates. Thereby, a method for creating a new operation curve with improved calculation efficiency is realized.

[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) Power running / brake coasting In the above-described embodiment, the entire curved portion is coasted as the coasting of the power running and brake. However, a part of the curved portion may be coasted. For example, the entire curved portion from the start point to the end point of a certain repowering has been described as a lame candidate, but the curved portion may be divided into first and second half to be separate lame candidates. Moreover, it is good also as 3 divisions or 4 divisions instead of 2 divisions of the first half. The same applies to the brake curve portion.
