Description

  The present invention relates to an operation diagram display device that displays a train operation diagram in a two-dimensional manner as train lines, and more particularly to a method for scrolling a screen displaying an operation diagram.

  The train schedule is displayed on the schedule. The operation diagram displays the station name on the vertical axis and the time on the horizontal axis, and the train schedule is displayed two-dimensionally as an oblique line segment. Such an inclined line segment is called a diamond line or a train line. When the operation diagram is displayed on the display device, only a part of the operation diagram is displayed on the screen. Therefore, when scrolling a screen along a train line, a vertical scroll bar and a horizontal scroll bar must be used alternately.

  The diamond display device described in Patent Document 1 is provided with a tracking scroll function for scrolling the display screen so as to follow the diamond designated by the operator. As the tracking scroll, there are an inclination tracking scroll for scrolling along a specified diamond inclination and a boundary point tracking scroll for scrolling at a specified boundary point of the diagram.

JP-A-8-44337

  In the conventional operation diagram scrolling method, the screen can be scrolled in the direction of train stripes, but it does not support various vehicle operations such as loopback operation, split operation, and merge operation.

  An object of the present invention is to provide a method capable of quickly and accurately scrolling an operation diagram even in the case of various vehicle operations such as turn-back operation, split operation, and merge operation.

  According to the present invention, when the train line selected by the operation of the wheel button is in the operation operation area of any of the return operation, split operation, merge operation, entry operation, and departure operation, the operation The train lines are read along the driving, and the screen is scrolled along the read train lines.

  According to the present invention, the screen scrolling operation that can follow various vehicle operations can be easily realized, so that it is possible to shorten the time required for determining the target train at the time of the schedule change schedule and grasping the influence on the operation partner train, etc. .

  Hereinafter, an embodiment relating to the present invention will be described in detail. FIG. 1 shows an outline of a train operation management system. The train operation management system of this example includes a plan diagram creation device 11, a diagram change device 12, an operation control device 13, a station system 14, and a diagram management device 15. The plan diagram creation device 11 has a function of creating a plan diagram and displaying it.

  The diagram change device 12 has three display functions: a plan diagram display function for displaying an operation planned train, a record diagram display function for displaying train travel results, and a plan diagram change function for inputting a schedule change. . The display function of the plan diagram will be described later with reference to FIG. Here, the plan diagram changing function will be described. The diagram change device 12 performs a diagram change in order to recover the train delay at an early stage when the diagram is disturbed due to an accident or failure. In the schedule change, it is necessary to first select a train to be changed, and to consider the influence on the operation partner train and the like.

  Usually, the train travel schedule is that the vehicle is operated from the time when the train leaves the garage until the driving section is operated several times before returning to the garage. Such vehicle operation is taken into consideration when changing the schedule. A typical example of vehicle operation is shown below.

(1) Turn-back operation in which passengers are transferred at the terminal station (2) Split operation in which one vehicle train is separated into a plurality of vehicle trains (3) Multiple vehicle trains are combined into one vehicle train (4) Entry operation to enter the garage from the main line (5) Departure operation to exit from the garage to the main line

  The operation control device 13 gives a control instruction to a traffic light or the like. The operation control device 13 has a function of displaying a track diagram and a train traveling position of an operation section under the jurisdiction of the train operation management system. An example of the display screen by the operation control device 13 will be described with reference to FIG.

  The station system 14 controls equipment such as traffic lights at each station to control the course of the train. The diagram management device 15 performs master management of the plan diagram, the actual diagram, and the change diagram.

  When the plan diagram creation device 11 creates the plan diagram, the plan diagram creation device 11 transmits it to the diagram management device 15. The diagram management device 15 transmits the received plan diagram to the diagram change device 12 and the station system 14. The station system 14 transmits the record schedule and train line information to the diagram management device 15. The diagram management device 15 transmits the record diagram and train location information to the diagram change device 12 and the operation control device 13. The diamond change device 12 transmits the changed diamond to the diamond management device 15. The diamond management device 15 transmits the changed diamond to the station system 14.

  The operation diagram display device of the present invention is realized by the plan diagram creation device 11, the diagram change device 12, and the operation control device 13 having a function of displaying an operation diagram.

  FIG. 2 shows a train streak display screen 24 and a mouse 25 with wheel buttons displayed on the diagram changer 12. A part of the operation schedule is displayed on the train line display screen 24. A mouse cursor 23 is displayed. The operation schedule includes a train line 21 and a train number 22. The horizontal axis of the service schedule is time, and the vertical axis is the station name. A vertical scroll operation area 26 is displayed at the left end of the train stripe display screen 24, and a horizontal scroll operation area 27 is displayed at the upper end. The method of using these operation areas 26 and 27 is known and will not be described in detail here.

  The mouse 25 with a wheel button has a wheel button 25A and a normal click button 25B.

  First, the user selects a desired train on the train stripe display screen 24. In order to select a train, the mouse cursor 23 is moved on the train line 21 or the train number 22, and the wheel button 25A is clicked. The selected train line is placed in the center of the screen. This is called screen centering.

  Next, the wheel button 25A is rotated. The screen is scrolled along the selected train line 21. The scroll amount is proportional to the rotation amount of the wheel button 25A.

  With reference to FIG. 3, the operation method of the wheel button 25A of the mouse | mouth 25 with a wheel button is demonstrated. The operation method of the click button 25B is known and will not be described in detail here. As shown in the figure, wheel button operations include a wheel click 301, a wheel down 302, and a wheel up 303. The wheel click 301 in FIG. 3A is a click of the wheel button 25A, whereby a train and a train line that are subject to screen scrolling are determined. This operation is used to redraw the screen with the position coordinate of the mouse cursor 23 as the display reference position (position at the center of the screen). The wheel-down 302 in FIG. 3B is to rotate the wheel button toward the front, whereby the screen scrolls in the future direction along the train line of the selected train. The wheel-up 303 in FIG. 3 (c) is to rotate the wheel button to the back, whereby the screen scrolls in the past direction along the train line of the selected train.

  The details of the screen scrolling method according to the present invention will be described with reference to FIG. FIG. 4A shows the train stripe display screen 24 before scrolling, and FIG. 4B shows the train stripe display screen 24 after scrolling. Here, for convenience of explanation, the scroll operation areas 26 and 27 at the periphery of the train stripe display screen 24 are omitted. As shown in the figure, the x-axis is taken in the time axis direction and the y-axis is taken in the station name axis direction.

  The center position of the screen before scrolling in FIG. 4A is set as a display reference position 44 before scrolling, and its coordinates are set as (x1, y1). In this example, the train 1111B and the train stripe are already selected and centering is performed. Therefore, the train line is arranged at the center of the screen, and the display reference position is arranged on the train line. Assume that the user performs wheel down. Thereby, the screen is scrolled in the future direction along the train stripe. The center position of the screen after scrolling is set as a display reference position 45 after scrolling, and the coordinates thereof are (x2, y2). The scroll amount is proportional to the wheel down amount, that is, the rotation amount of the wheel button 25A. Hereinafter, a method of obtaining the coordinates (x2, y2) of the display reference position after scrolling given that the rotation amount of the wheel button 25A is given will be described. Set as shown.

x1 x coordinate of display reference position before scrolling
y1 ... y-coordinate of display reference position before scrolling
x2: x coordinate of the display reference position after scrolling
y2: y coordinate of the display reference position after scrolling
t: Horizontal scrolling by wheel operation
n1 ... Distance on the coordinate in the x direction between station 3 and station 4
n2 ... Distance on the coordinate in the x direction between station 3 and the display reference position after scrolling
m1 ... Distance on the coordinate in the y direction between station 3 and station 4
m2 ... Distance on the coordinate in the y direction between station 3 and the display reference position after scrolling

The x-coordinate (x2) of the display reference position after scrolling is the sum of the x-coordinate (x1) of the display reference position before scrolling and the horizontal scrolling amount t, and is expressed by the following equation.
x2 = x1 + t (Formula 1)

The horizontal scroll amount t is obtained from the rotation amount of the wheel button 25A. In this example, when the horizontal scrolling amount t is searched from the plan diagram of the train 1111B, it is found that it corresponds to the time n1 from the departure time of the station 3 to the arrival time of the station 4 of the train 1111B. Therefore, the x-coordinate (x2) of the display reference position after scrolling is expressed as follows:
x2 = x1 + n1 (Formula 2)

On the other hand, the y coordinate (y2) of the display reference position after scrolling is obtained by the following equation.
y2 = y coordinate of station 3 + m2 (Formula 3)

The y coordinate of the station 3 is obtained from the plan diagram. m2 is obtained by the following proportional expression.
m2 = (n2 / n1) × m1 (Formula 4)

Note that n1, n2, and m1 are expressed by the following equations.
n1 = station 4 arrival time coordinate-station 3 departure time coordinate (Formula 5)
n2 = x2-departure time coordinates of station 3 (Formula 6)
m1 = y coordinate of station 4−y coordinate of station 3 (Formula 7)

  Thus, by substituting Equations 5 to 7 into Equation 4 to obtain m2, and substituting m2 into Equation 3, the y-coordinate (y2) of the display reference position after scrolling is obtained.

  By setting the coordinates (x2, y2) of the display reference position after scrolling thus obtained as the center position of the screen, the screen scrolling result shown in FIG. 4B can be obtained. Note that the display reference position after scrolling cannot be set at the center position of the screen in the vicinity of the limit coordinate of the vertical scroll. In such a case, only horizontal scrolling is performed.

  FIG. 5 shows a state in which a part of the drawing information 501 is extracted and the train streak display screen 24 is sequentially extracted. In this example, when a train or train stripe is selected by clicking the wheel button 25A, the screen is centered. Next, when the wheel button 25A is rotated, the screen scrolls along the train stripe. The scroll amount is proportional to the rotation amount of the wheel button. The screen is scrolled according to the selected train. In this example, when the selected train performs turn-back operation, split operation, merge operation, entry operation, departure operation, etc., the screen is scrolled accordingly, which will be described in detail below. .

  The screen scrolling method according to the present invention will be described in detail with reference to FIG. In order for the scrolling operation of the screen to follow various vehicle operations, it is necessary to replace the selected train.

  FIG. 6 (a) shows a train replacement method when there is a turn-back operation 51, an entry ward 52 entering the garage, and an exit ward 53 leaving the garage. In this example, the train 1111B performs a loopback operation at the station 1 and becomes the next operation train 2222B. Accordingly, when the display reference position reaches the station 1 by the wheel operation, the train 1111B is replaced with the operation partner train 2222B. In this example, train 2222B enters the garage at station 2 and then exits and travels as train 3333B. Therefore, when the display reference position reaches the entry time of the station 2, the train is read as the operation partner train 3333B. Further, train 3333B performs a loopback operation at station 1 and reads as train 4444B.

  FIG. 6B shows a case where the merge operation 54 is operated. Train 1111B operates jointly with other train 3333B at station 2. Therefore, when the display reference position reaches the station 2 by the wheel operation, the train 1111B is replaced with the operation partner train 3333B.

  FIG. 6C shows a case where the split operation 55 is operated. The train 1111B is partly separated at the station 2 and then split operation is performed with the separated train 3333B. Therefore, when the display reference position reaches the station 2 by the wheel operation, there are a plurality of operation partner trains, so the train cannot be automatically read.

  Therefore, when there are a plurality of operation partner trains, the train selection menu 56 is displayed, the selected train is determined by clicking the mouse and the screen scrolling by the wheel operation can be continued.

  Furthermore, because it is easy to overlook the selected train when checking the train schedule on a high-density route, when the selected train is determined and changed, the color change display is performed for all train lines that are operationally connected to the selected train. .

  With reference to FIG. 7, the function which displays the train stripe display screen of the diagram change apparatus 12 by this invention is demonstrated. As shown in the figure, the diagram change device 12 includes a diagram information database 31, a drawing information database 33, a drawing information creation processing unit 32, a train stripe drawing processing unit 34, and a screen scroll control processing unit 35. The diagram information database 31 stores a plan diagram. The drawing information database 33 stores train numbers, train lines, and drawing coordinates.

  The drawing information creation processing unit 32 (1) acquires a plan diagram from the diagram information database 31, creates drawing information such as a train number and drawing coordinates based on the plan diagram, and (2) draws in the drawing information database 33. Write information.

  The train line drawing processing unit 34 (3) acquires drawing information from the drawing information database 33 and (4) performs train line display on the train line display screen 24.

  The screen scroll control processing unit 35 acquires (5) mouse coordinates (position coordinates instructed by the mouse cursor 23) based on the wheel click operation of the mouse 25 with wheel buttons, and (6) coordinates from the drawing information database 33. The train number of the selected train is acquired by the search. Furthermore, (7) according to the wheel button operation, (8) obtain the plan schedule of the selected train, calculate the scroll display reference position (coordinates of the selected train to be displayed in the center of the screen), and draw the train line (9) A screen redrawing instruction after scrolling is issued to the processing unit 34. As a result, the train line drawing processing unit 34 performs (10) screen scroll display on the train line display screen 24.
