It is a program that performs. In the present embodiment, the driving curve automatic creation unit 17 creates a driving curve by the method described in “Driving Theory” issued by the Japan Railway Driving Association.

  FIG. 2 is a diagram illustrating a hardware configuration example of the operation curve creation device 1 illustrated in FIG. 1. As shown in the figure, a computer applied to the operation curve creating apparatus 1 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an input / output interface 104, and a system. A bus 105, an input device 106, a display device 107, an auxiliary storage device 108, and a communication device 109 are included.

  The CPU 101 is a processing device that executes various types of arithmetic processing using programs and data stored in the ROM 102 and the RAM 103. The ROM 102 is a read-only storage device that stores basic programs and environment files for causing the computer to function. The RAM 103 is a storage device that stores a program executed by the CPU 101 and data necessary for executing each program, and can be read and written at high speed. The input / output interface 104 is a device and a program that mediate connections between various hardware and the system bus 105. A system bus 105 is an information transmission path shared by the CPU 101, ROM 102, RAM 103, and input / output interface 104.

  The input / output interface 104 is connected to hardware such as an input device 106, a display device 107, an auxiliary storage device 108, and a communication device 109. The input device 106 is a device that processes input from a user, and is, for example, a keyboard or a mouse. The display device 107 is a device that displays a calculation result, a creation screen, and the like to the user, and is, for example, a CRT, a liquid crystal display, a plasma display, or the like. The auxiliary storage device 108 is a large-capacity storage device that accumulates various programs and data related to the operation curve creation processing, and is, for example, a hard disk device.

  Hereinafter, the change of the screen display in the operation curve creation device 1 configured as described above will be described with reference to the drawings. FIG. 3 is a diagram showing a display example of an operation curve creation screen displayed with reference to the ground facility information table 11B shown in FIG. As shown in the figure, the driving curve diagram expressing the driving curve is a graph represented with the traveling speed of the train as the vertical axis and the distance from the reference station as the horizontal axis. The distances to the station X and the station Y, which are ground facilities, are recorded on a table, and various terrain information such as speed limits and gradients between the stations are also represented by graphics. Also, the time-distance required time curve and the power consumption-distance power consumption curve are expressed by displaying the required time and power consumption between the stations together on the vertical axis.

  FIG. 4 is a diagram showing a display example when an operation curve is created on the operation curve creation screen shown in FIG. Here, a case is shown in which an operation curve having the shortest required time is created in accordance with the “operation theory” described above. The operation curve may be created manually, but the operation curve information that is automatically created by the operation curve automatic creation unit 17 and stored in the database unit 11 (operation curve information table 11D) is read out. To do. In FIG. 4, the operation curve is represented by a solid line. The required time curve is represented by a broken line, and it can be seen from this required time curve that 145 seconds are required from station X to station Y. Further, the power consumption curve is represented by a one-dot chain line, and it can be seen that 45 kW / h of power is required by traveling from the station X to the station Y by the power consumption curve.

  However, if the result of FIG. 4 remains as it is, there is a portion where acceleration and deceleration are performed in a short time between the speed limit B and the speed limit C. This is a good driving curve from the viewpoint of ride comfort and energy saving. I can't say that.

  Therefore, consider the case where the driving operation that is being performed from the end point of the speed limit B is changed as follows. When the user moves the mouse cursor in the vicinity of the end point of the speed limit B, an identification display is made on the screen so that a point where the driving operation can be changed can be selected. The points where the driving operation can be changed include a speed limit start / end point, a stop point of the station, a change point of the currently created driving operation, and the like. Then, the starting point of the provisional running curve is determined by clicking the mouse with the identified and displayed coordinates. FIG. 5 is a diagram illustrating a display example when a creation start point is designated on the operation curve on the operation curve creation screen illustrated in FIG. 4. As shown in the figure, when the creation start point of the provisional operation curve is determined, an arrow (forward / reverse direction) for selecting the creation direction of the provisional operation curve is displayed on the creation start point. . When the user designates the creation direction, a temporary operation curve corresponding to each driving operation is displayed together with a list of driving operations that can be selected at the creation start point.

  FIG. 6 is a diagram showing a display example when the creation direction is designated as the forward direction on the operation curve creation screen shown in FIG. Here, provisional driving curves created corresponding to the list of driving operations are respectively displayed by dotted lines. The user arbitrarily designates a driving operation by a mouse operation from the displayed list of driving operations. When the user designates a driving operation from the list by operating the mouse, the display is switched to a new driving curve created based on the temporary driving curve and the existing driving curve on the driving curve creation screen.

  In addition, in FIG. 6, the operation was performed in order to consider performing the coasting operation from the end point of the speed limit B. However, since this section has a steep downward slope, the speed does not increase even if the coasting operation is performed. If it turns out that it rises, the forward direction creation from this point is stopped, and the provisional operation curve in the reverse direction from the start point of the speed limit C may be created again. In this case, the mouse cursor is moved near the start point of the speed limit C, and the start point of the speed limit C is identified and displayed. The mouse operation is performed in the same manner as described above, and the reverse direction is selected as the creation direction instruction, so that the temporary operation curves for all the driving operations are displayed again. FIG. 7 is a diagram illustrating a display example when the creation direction is designated in the reverse direction on the operation curve creation screen illustrated in FIG. 5. From this result, if it is evaluated that the coasting operation in the reverse direction from the starting point of the speed limit C is the most expected driving curve, this driving operation is determined, and editing of the driving curve by manual operation is performed. Complete. FIG. 8 is a diagram showing a display example of a new driving curve created by designating the driving operation as coasting on the driving curve creation screen shown in FIG.

  FIG. 9 is a flowchart showing a specific example of the manual editing process in the operation curve creating apparatus 1 shown in FIG. Here, a case where an existing operation curve is displayed on the operation curve creation screen as shown in FIG. 4 will be described as an example.

  In S901, it is determined whether or not the current mouse cursor position is about the distance where the station exists and the speed is near the point of 0 km / h. In addition, it is determined with reference to station information which is one of the ground facility information stored in the ground facility information table 11B. Here, if it is determined that the station is near the point where the speed is 0 km / h (S901: Yes), the operation curve creation screen display unit 13 identifies and displays the station point (S902). The process proceeds to S903. On the other hand, when it is determined that the distance is not as long as the station is present, or not near the point where the speed is 0 km / h (S901: No), the process proceeds to S903.

  In S903, when the current mouse cursor position is near the speed limit start distance and the speed is near the speed limit, or when the speed limit is near the end distance and the speed is near the speed limit It is determined whether or not to do. The speed limit start distance, end distance, and speed limit value are determined with reference to speed limit information stored in the speed limit information table 11C. If it is determined that the current mouse cursor position meets one of the above two conditions (S903: Yes), the running curve creation screen display unit 13 identifies and displays the speed limit start point or end point ( The process proceeds to S904) and S905. On the other hand, when it is determined that the current mouse cursor position does not correspond to any of the above two conditions (S903: No), the process proceeds to S905.

  In S905, it is determined whether or not the current position of the mouse cursor is near the start point or end point of the existing driving curve. The driving curve information is combination data of distance, speed, and driving operation, and the start point and end point of a data group in which the same driving operation continues when the data are arranged in order of distance are identification display targets. Here, when it is determined that the current position of the mouse cursor is in the vicinity of the start point or end point of the existing driving curve (S905: Yes), the point is identified and displayed (S906), and the process proceeds to S907. On the other hand, if it is determined that the current position of the mouse cursor is neither near the start point nor the end point of the existing driving curve (S905: No), the process proceeds to S907.

  In S907, when the user designates the position identified or displayed or an arbitrary coordinate position as a creation start point by a mouse operation, the designation information is output from the input unit 14 to the provisional running curve creation unit 15.

  In S908, the creation direction of the temporary operation curve is displayed so as to be designated from the forward direction and the reverse direction with the creation start point as a reference. When the user designates the creation direction by a mouse operation, the designation information is output from the input unit 14 to the provisional running curve creation unit 15.

  In step S909, it is determined whether or not the creation direction designated by the mouse operation is the forward direction. Here, when it is determined that the forward direction is designated (S909: Yes), provisional running curves are created for all driving operations that can be selected for the designated coordinate position and forward direction (S910), and the process proceeds to S912. . On the other hand, when it is determined that the reverse direction is designated (S909: No), a provisional operation curve is created for all driving operations selectable in the reverse direction (S911), and the process proceeds to S912. The temporary operation curve has a point at which the speed becomes 0 km / h (intersection with the distance display axis), a point at which the speed limit becomes the maximum speed, or a point at which the speed limit or existing driving curve intersects. Create by calculating.

In S912, the temporary running curve created corresponding to all driving operations with the creation start point as a reference is displayed as a candidate on the running curve creation screen as shown in FIG. 6 or FIG.
In S913, the user arbitrarily designates a driving operation by a mouse operation from the displayed list of driving operations. When the user designates the driving operation by the mouse operation, the designation information is output from the input unit 14 to the temporary driving curve creating unit 15, and the temporary driving curve related to the designated driving operation and the existing driving curve are displayed on the driving curve creating screen. The display switches to a new operation curve created based on the above.

  In S914, it is determined whether or not the operation curve has been edited. Specifically, the determination is made based on whether or not the user has pressed a completion button (not shown) on the operation curve creation screen. If it is determined that editing has been completed, the process proceeds to S915. On the other hand, if it is determined that the editing has not been completed, the process returns to S901, and the processes of S901 to S914 are repeated until the editing is completed.

  In S915, the database unit 11 (operation curve information table 11D) is updated with the operation curve information based on the new operation curve displayed as shown in FIG. 8 on the operation curve creation screen, and the process ends.

  As described above, according to the present embodiment, it is not necessary for the operator to calculate a complicated operation curve in advance when the operation curve is manually created, and (1) designation of the creation start point, (2) By simply repeating the three steps of specifying the creation direction and (3) specifying the driving operation (temporary driving curve), it is possible to create an operating curve in a short time. That is, by temporarily displaying all the driving operations from the creation start point, it is possible to determine which driving operation can be created by designating which driving operation. In addition, it is possible to facilitate the creation of a driving curve even if it is not an expert by assisting the designation of the creation start point, creation direction, and driving operation of the provisional driving curve during manual editing. Further, if the mouse cursor is moved on the driving operation, it is preferable that the temporary driving curve created by the driving operation is highlighted and more easily discriminated.

  In addition, since the time curve and power consumption curve are temporarily displayed in the overall operation curve created by each operation, how much the operation time and power consumption are affected when each operation is specified. You can also know in advance.

  In the above embodiment, 7 types of operation (4 notches / 3 notches / 2 notches / constant speed / coasting / slow brake / rapid brake) are considered. It is the same as the level that can be specified from the computer and can be increased or decreased. Further, the arrangement order may be the same order as that of the master computer, and the design can be arbitrarily changed according to the fixed order or the slope of the curve to be created.

  Furthermore, although the creation direction is specified in the above-described embodiment, provisional operation curves in both directions may be created without specifying the creation direction. In that case, the operation curve can be manually created in two steps: designation of the start point and selection of the temporary operation curve.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
