Description

  The present invention relates to a train diagram display processing method, a train diagram display processing system, and a train diagram display processing program. Specifically, a change occurs in a drawing state of station premises information displayed on a layout of a train diagram. Even in this case, the present invention relates to a technology that can execute GUI processing related to a train diagram and station premises information at high speed and without any problem on display.

  A train diagram used by railway personnel generally has an enormous amount of information and a large display size on a display or the like. Therefore, when this train diagram is to be displayed on the information processing apparatus, the train diagram may not fit within a predetermined display range on a display or a window. In this case, the information processing apparatus responds to the display request from the user by performing, for example, a display range transition process using a scroll bar or a scroll box. For example, of the two vertical and horizontal dimensions in the scroll box, one dimension indicates a distance-related axis, and the other dimension indicates a time axis. In general, in a train diagram, as a dimension of the distance relationship, a diagram showing a station flow (continuous) for each line section shown in the train diagram is widely used.

  In such a train diagram, as the train information, a trajectory of a train that operates in accordance with the passage of time on the time axis is indicated by diagonal lines. In general, this diagonal line is called “streak”. The train diagram further includes symbols representing train operation status. Various types of train information displayed in these train diagrams are divided into information about the distance between stations and information about the station premises. In the following description, information relating to changes in the train operation state performed in the station, such as information such as the number of the train line where the train stops and the number of lines used for turning back, is defined as “station premises information”. Hereinafter, a general method for displaying the station premises information will be described with reference to the above.

(1) Regarding the display of the station premises area In general, the station premises diagram is widely used to display the station premises information defined above. In this station yard diagram, one of the two vertical and horizontal dimensions indicates the passage of time, and the other one indicates the number of the target station. In the following description, the display area of the station yard diagram displayed as a part of the train diagram is defined as the station premises area in the train diagram. As an example of the station premises area, (6211), (6214), (6217) in FIG. 4 can be assumed.

(2) About the display position of the station premises area There are two conventional methods for displaying the station premises area defined above on the train diagram. One is to display the station area in a fixed position on the train diagram (fixed layout), and the other is to display the station area in accordance with the display position of the target station in the train diagram. (Variable layout).

(3) Regarding the fixed layout and variable layout, there is a method of displaying the station precinct area at a fixed position as described above. In this case, the layout size of the station area display window and the like is determined in advance according to the distance and time zone of the station area to be displayed. Therefore, the layout of the train diagram is also a fixed layout.

  On the other hand, there is a technique that employs a variable layout that does not display the station premises area at a fixed position. In this case, the station premises area is connected with the position of the target station and displayed. In this method, it is possible to insert a station area in the middle of the train diagram and display a plurality of station areas simultaneously. In addition, the user can select whether or not to display the station premises on the train diagram, and the layout size changes depending on the number of displayed station premises areas and the size of the station premises area. Therefore, the layout of the train diagram is a variable layout.

  As a display processing technique, even in a display system whose layout changes depending on the size setting of characters and display windows, a technique for realizing high-speed and high-precision scroll bar display control with a small processing time and resources (see Patent Document 1). ) Etc. have been proposed.

JP 2003-330700 A

  However, there are some problems in the conventional situation as described above. For example, there are the following problems related to the “variable layout” described above. For example, when various layout changes such as display / non-display switching of the station precinct area and a change in the number of displays are performed, it takes time for the GUI processing, and the response of the GUI of the train diagram may be delayed.

  As a reason why the GUI processing takes time in this way, for example, the layout size of the entire train diagram may change depending on the size of the station area to be changed due to the change of display / non-display of the station area. In such a situation, the layout size of the entire train diagram cannot be calculated in advance, and each drawing element needs to be laid out again when actually displayed. In addition, the larger the number of drawing elements in the train diagram, the more time is required for the layout process. In the following description, each of the drawing contents necessary for displaying the train diagram on the display (for example, straight line drawing, character string drawing, circle drawing, filled circle drawing, polygon drawing, etc. can be considered). It is defined as “drawing element”.

  In addition, as another problem, there is a problem when a drawing related to station premises information is displayed on a train diagram even when the station premises area is not displayed. For example, when a user selects a certain station and wants to display the station premises information, not only the drawing element related to the station premises information is displayed immediately below the corresponding station display, but also the line (distance direction) of the corresponding station. The drawing element may be added or deleted on the position of (axis line = station line). An example of such a situation is shown in FIG. The on-premises information 14120 and 14130 in FIG. 14 is a drawing showing “turnback” information. This return information is displayed even when the station area is not displayed. On the other hand, when displaying the return information in the station precinct area, the drawing related to the return must be deleted from the area between the stations.

In addition, as a method of dividing the display of the train diagram for each station, for example, a method of dividing by a station line is common. This station line refers to a line indicating the position in the distance dimension of the corresponding station in the train diagram. In the station line in the example of FIG. 14 , the lines (14140), (14150), and (14160) correspond thereto.

For example, in order to display the station precinct area of all stations, it is assumed that the train diagram is divided by a division method based on the station line, and the divided train diagram is combined with the station premise area. In that case, since the folded drawings 14220 and 14230 are combined while being displayed as in the example of the display 14210 in FIG. 14, the display is erroneous and has no continuity as a train diagram.

Further, as another problem, there is a problem that occurs when there is a drawing across an area between stations or an area within a station. Upon division of the train schedule diagram, it is conceivable to simply split the station yard area and the inter-station area relative to the train station, the symbols across the station between areas or station yard area, drawing such train number generated There is. In this case, since the drawing over the area is divided in the inter-station area or the station premises area, depending on the drawing contents such as the symbol and the train number, it may be difficult to redraw in combination over the area. There is also. Examples of drawing elements that are difficult to combine across these areas include the train number 3110, the train division symbol 3120, the train number 3130, and the like in FIG. For example, in the situation illustrated in FIG. 7, when the station area “B station” is displayed, the train number, the train division symbol, and the like are displayed broken.

  Further, as another problem, there is a problem of relayout processing accompanying the occurrence of an event. For example, when a change in train information, such as a train time or train return information, occurs, a re-layout process may be performed to display new train information in which the change has been made. In this case, too, the GUI processing takes time, and there is a problem that the response of the GUI in the train diagram becomes slow.

  On the other hand, for example, even if the technique shown in the above-mentioned Patent Document 1 is applied, it is not possible to deal with a situation unique to a train diagram such as a case where a layout is divided into a plurality of parts in a train diagram and there is a drawing across each layout. In general, there is no train information in the train diagram corresponding to the delimiter information for display such as tags, and the train information cannot be applied.

  Accordingly, an object of the present invention is to provide a technology capable of executing GUI processing relating to a train diagram and station premises information at high speed and without any problem on the display even when there is a change in the drawing situation of the station premises information displayed on the layout of the train diagram. It is to provide.

In the train diagram display processing method of the present invention that solves the above problems, an information processing apparatus that performs train diamond display processing performs the following processes A to E.

Process B is performed.

--- System configuration example ---
Hereinafter, embodiments of the present invention will be described with reference to the drawings as appropriate. FIG. 1 is a configuration diagram of a train diagram display processing system. The train diagram display processing system 200 according to the present embodiment performs high-speed and display GUI processing relating to train diagram diagrams and station premises information even when there is a change in the drawing status of station premises information displayed in the layout of the train diagram diagram. An information processing apparatus that can be executed without any problem and is assumed to be an information processing apparatus such as a PC or server. Hereinafter, the configuration and functions of the train diagram display processing system 200 will be described.

  The train diagram display processing system 200 (hereinafter, system 200) includes a CPU (Central Processing Unit) 204, which is a central processing unit for controlling the apparatus and calculating / processing data, as a matter of course as an information processing apparatus, A memory 203 that temporarily stores a program and can be directly read / written by the CPU 204, a non-volatile storage unit 201 that stores data and programs so that the data and programs are not lost even when the power is turned off, and data calculation / processing for the user The hardware configuration includes an output device 206 for displaying the result on a display and the like, and an input device 205 for receiving keyboard input, mouse input, and the like from the user. The CPU 204 reads and executes the program 202 stored in advance in the storage unit 201 or the like, thereby implementing the functional unit necessary for this embodiment.

  At the time of activation, the system 200 receives train information data (from the train information management table 2110), basic information data (from the basic information management table 2120), display setting data (display setting information management table 2130) from the storage unit 201. Read more). These data are the same as those used in the existing train diagram display system. The train information data is, for example, data such as train number information, train-to-train connection information at the time of return, number information to be used, division / merging information, and the like. Moreover, it is the basic information data and the data of the position order of the stations in the line area regarding each line area. Further, the display setting data is data of line sections and position order of the line sections. As another example, these data may be acquired from another device via a communication network.

Since the drawing element management table 2140 and the GUI display data 2150 are data generated after the program 202 is started, they are managed only when the program is started. Therefore, these data may be stored in a readable / writable volatile memory (Volatile Memory). As this volatile memory, for example, a RAM (Random Access Memory) can be assumed. The GUI display data 2150 corresponds to various GUI-related data and a divided layout. A structural example of the drawing element management table 2140 will be described later.

  Examples of the functional units held by the system 200 include a diagram display unit 2220, a GUI display unit 2230, and a drawing element management unit 2240. Here, the GUI display unit 2230 manages GUI events and GUI parts. As the GUI parts, for example, a scroll bar, a menu, a dialog box, and the like can be assumed. The GUI display unit 2230 stores each divided layout in the GUI display data 2150. As a data format for storing each divided layout, Pixmap, JPG, Bitmap, and the like can be assumed (depending on the implementation environment).

  The drawing element management unit 2240 is a processing unit for performing calculation (13140) of drawing element information described later. In addition, the diagram diagram display unit 2220 executes a divided train diagram display process (a process along the flow of FIG. 2) of the present embodiment. Therefore, the GUI display unit 2230 and the drawing element management unit 2240 are executed as necessary.

--- Processing example ---
FIG. 2 is a flowchart showing a processing procedure example 1 of the train diagram display processing method of this embodiment, and FIG. 3 is a flowchart showing a processing procedure example 2 of the train diagram display processing method of this embodiment. Hereinafter, it is assumed that the system 200 executes all processes unless otherwise specified. Here, the step (1110) of “calculating each divided layout” in the flowchart of the processing procedure example 1 will be described. First, as a first step, the diagram display unit 2220 executes the drawing element management unit 2240 to execute a step (FIG. 3, 13110) of acquiring each data of a line section and a station position order.

  In this step, the drawing element management unit 2240 executed by the diagram display unit 2220 reads the basic data, display setting data, and train information data from the storage unit 201. The drawing element management unit 2240 stores the data read here in the drawing element management table 2140. For example, the basic data includes fixed data of the railway network, for example, station names, distances between stations, line names, line area information, and the like. The display setting data includes, for example, display colors of stations and trains shown in the divided layout, sizes of fonts, and the like necessary for setting the divided layout.

  In addition, the diagram display unit 2220 calculates the size of each divided area based on the basic data and display setting information obtained in step 1110. In this case, the diagram diagram display unit 2220 determines each divided layout to be a display area on the output screen based on the number of patterns of each divided layout and the size of each divided layout from the position order data and the display setting data. Video area (for example, data composed of a rectangular divided layout size and display coordinates on the coordinate system of the display screen) is specified and the corresponding data is secured (FIG. 3, 13120). In order to store the information on the video area, the diagram display unit 2220 executes the GUI display unit 2230. Meanwhile, the GUI display unit 2230 stores information on the video area in the GUI display data 2150.

Processing related to the video area will be described below. By the way, even if the station yard area (a set of drawing elements in the station premises) is not displayed on the train diagram, the drawing related to the station premises information is displayed on the train diagram (= drawing elements between stations and And a drawing element in the station premises arranged in the inter-station area of the corresponding station indicated by the station). In the present embodiment, in order to accurately cope with this situation, three patterns are assumed according to the display state of the station premises area. The diagram display unit 2220 creates a plurality of inter-station areas (= first to third divided layouts) according to each pattern, and manages each area individually. In the example of FIG. 4, (4210), (4213), (4216), and (4219) correspond to the first divided layout, and (4211), (4214), and (4217) correspond to the second divided layout. In the third divided layout, (4212), (4215), and (4218) correspond to this.

  FIG. 4 shows an example in which two divided layouts are created for the inter-station area between the “B station” station line and the “C station” station line. A divided layout 6216 in the figure is an inter-station area displayed when displaying the station precinct area of “C station”. On the other hand, the divided layout 6218 is an inter-station area that is displayed when the “C station” station area is not displayed.

  Subsequently, each of the three patterns will be described. The first pattern is a pattern in which there are no drawing elements related to the station premises above and below the station line when the station premises area is in a non-display state (= pattern that can correspond to the first to second divided layouts). The second pattern is a pattern in which the station premises area has a drawing element related to the station premises on the station line when the station premises area is not displayed (= pattern that can correspond to the first to third divided layouts). The third pattern is a pattern in which there are drawing elements related to the station premises above and below the station line when the station premises area is not displayed (= pattern that can correspond to the first to third divided layouts).

In the case of the first pattern, the line area top area, the area between the lowermost line area and the scroll window, and the display between stations are not changed by changing the display status of the station area. Therefore, only one type of divided layout is required for one train diagram. The number of divided layouts can be calculated according to the following formula.

-Number of division layouts = Line area top area [1] * 1 + Number of stations * 1 + Number of line section areas * 1 + Area [1] between the bottom line area and scroll window + Number of stations on the station ... (Formula 1 )

On the other hand, in the case of the second pattern, because the display on the station line differs depending on the display status of the station area, the line top area and the inter-station area are displayed for station area display and for station area non-display. Therefore, two types of divided layouts are required in each area. Therefore, the number of divided layouts is calculated according to the following formula 2.

・ Number of division layouts = Line top area [1] * 2 + Number of stations * 2 + Line section area * 2 + Area [1] between the bottom line section and scroll window + Number of stations on the station ... (Formula 2 )

In the case of the third pattern, the display on the station line and the display below the station line differ depending on the display condition of the station area, so the inter-station area is used for displaying and hiding the upper station area, and in the lower station area. For the display and non-display of the area, four types of divided layouts are required in each area. Therefore, the number of divided layouts is calculated according to the following Equation 3.

・ Number of division layouts = Line top area [1] * 2 + Number between stations * 4 + Number of line sections * 4 + Area between the bottom line and scroll window [1] * 2 + Number of stations 3)

As a specific example, a case will be described in which the number of divided layouts is calculated for the second pattern under the situation of FIG. In the example of the divided layout of the train diagram shown in FIG. 4, the plan is a divided layout for one line section and three stations (each station A to C). The order of the stations where the train travels in the relevant line section is A station → B station → C station. In this case, each area of the line area top area, the area between stations A and B, the area between stations B and C, and the area between the bottom line area and the scroll window (corresponding to the divided layout) Can be assumed. Further, as the station premises area, an A station premises area, a B station premises area, and a C station premises area can be assumed. When the number of divided layouts = the number of areas is calculated according to Equation 2, the number of divided layouts is “10” as described below.

-Number of stations [2] * 2+ Number of stations in the station [3] + Number of top areas in the line section [1] * 2+ Number of line section areas [0] * 1 + Area between the bottom line section and the scroll window * 1 = 10 ... (Formula 4)

Regarding the size of each divided layout, for example, the size of the line section top area, the size of the area between stations, the size of the line section area, and the size of the area between the bottom line section and the scroll window are defined in advance by the user. And obtained from the display setting data. On the other hand, the size of the station area may vary depending on the number of lines. In this case, the size of the station area is calculated based on the following calculation method.

・ Station area size = (Number of lines-1) * Size between lines + Upper margin size + Lower margin size ... (Formula 5)

  Since the number, size, etc. of the divided layouts corresponding to the inter-station area and the station premises area are obtained as described above, the diagram diagram display unit 2220 then adds the time axis and station axis information to the divided layout. Processing is performed (FIG. 3, 13130). In this case, when the step is executed, the divided layouts are in an initial state, and a user can freely set a time axis line, a station line, and a number line. Up to this step, the time-related axis line, station line, and number line have been set to the divided layout. Naturally, the drawing data such as the axis line and the station line set here is stored in association with the corresponding divided layout in the system 200.

  Next, the diagram display unit 2220 calculates drawing element information (FIG. 3, 13140). A specific example of this step will be described below. In addition, FIG. 5 and FIG. 6 shall be used for description of the said step (13140).

  In this case, first, the drawing element management unit 2240 calculates the data of the drawing element management table 2140 based on the data of the train information management table 2110. As an example of the train information management table 2110, FIG. 5 shows some pieces of train information (1 to n) and train information items 4110 constituting the train information. The train information item 4110 includes, for example, information such as train number information, time information, train-to-train connection information, line number information to be used, and division / merging information.

  In such a case, the drawing element management unit 2240 performs layout calculation such as calculation of the size of the drawing elements and display coordinates when the information of each train information item 4110 of each train information is displayed on the train diagram display. For example, in the coordinate system of the corresponding divided layout, this calculation is relative to the arrangement position of the time axis, station line, streak, etc. (for example, the train number on the XX line drawing of XX station at XX time) Is calculated), the coordinates of the position separated from the display coordinates of the corresponding number line by a predetermined distance are calculated, and data such as the display coordinates and size of each drawing element is obtained. About the data obtained here, it sets to the drawing element table 5210 regarding an applicable train. In this way, by managing each drawing element with coordinate values, for example, at the time of a re-display process that requires screen refreshing, the layout information from the train information management table 2110 or the like is not re-laid out (the previous steps). The necessary display coordinate values are obtained from the drawing element table 5210 managing the coordinate values, and the corresponding drawing elements are displayed on the screen.

  The data calculated above and set in the drawing element table 5210 will be described with reference to FIG. The drawing element table 5210 includes data of drawing element-specific parameter data 5212. This data is individual data according to each drawing element, for example, the length of one side when the drawing element is a square, and the radius when the drawing element is a circle. The drawing element table 5210 includes a divided layout ID 5213. This data is information for identifying in which divided layout the corresponding drawing element is drawn, in other words, which division layout dimension (coordinate system) is used to identify the coordinates of the drawing element calculated. It is information for. In addition, the drawing element table 5210 includes divided layout straddling identification information 5215. This data is identification information indicating whether the display coordinates of all the graphics of the drawing element fall within the display range of the division layout in the relationship between the drawing element and the divided layout associated with the drawing element. That is, when the range of the display coordinates of the drawing element does not fit within the range indicated by the display coordinates of the divided layout, the corresponding drawing element spans between the divided layouts. The drawing element table 5210 includes work area identification information 5214. This data is data set in GUI event processing to be described later.

  Next, the diagram display unit 2220 (or the drawing element management unit 2240) draws the drawing elements for which the necessary data is obtained in the step 13140 on the corresponding divided layout (FIGS. 3 and 13150). ). Each drawing element data calculated in step 13140 stores a divided layout ID indicating a divided layout to be drawn. Accordingly, the diagram display unit 2220 can distinguish which divided layout should be drawn for each drawing element by this divided layout ID. The diagram diagram display unit 2220 that has identified the divided layouts to be drawn in this way displays the drawing elements that do not cross between the divided layouts (= the drawing elements that the divided layout crossing identification information 5215 crosses between the divided layouts). Is drawn (13140).

  The drawing elements straddling the divided layouts are not drawn in this step for the following reason. For example, if the display size of the inter-station area that can be secured on the screen (width in the distance direction) is narrower than a predetermined value and the size of the drawing element displayed in the divided layout between the corresponding stations is greater than or equal to the predetermined value, from the inter-station area The drawing element protrudes and straddles a divided layout between other adjacent stations. FIG. 7 shows an example of a drawing element straddling between divided layouts. In this case, there is a drawing element 3120 that straddles the divided layout of the A station and the B station. As described above, when there are drawing elements straddling between the divided layouts, the display of the divided layouts differs depending on the display / non-display status of the station premises area. For this reason, fixed display cannot be handled for each divided layout. Therefore, at this stage, the drawing elements (those extending between the divided layouts) cannot be drawn in the divided layout.

  Then, it returns to the processing flow of FIG. Here, the GUI display unit 2230 obtains the status of the station premises display, for example, from the GUI display data 2150 of the storage unit 201 (1120). The station premises display status is information indicating whether or not there is a drawing instruction in the station premises regarding the predetermined station in the input device 205.

  Next, the GUI display unit 2230 executes train diagram layout creation (1130). This process will be described with reference to FIG. In this case, the GUI display unit 2230 performs division layout combination processing according to the station premises display already obtained in step 1120. For example, the layout example 7410 is an example in which the user instructs to display the premises information of all stations (A station to C station). At this time, the GUI display unit 2230 combines the divided layouts 7110, 7120, 7130, and 7140 related to each station and the divided layouts 7210, 7220, and 7230 related to each station premises to create a train diagram layout. In this case, the process of connecting and displaying the divided layouts in the corresponding station under the divided layout between certain stations is repeated for each station. The result of the combination of the divided layouts thus obtained is a train diagram layout of divided layout 7110-divided layout 7210-divided layout 7120-divided layout 7220-divided layout 7130-divided layout 7230-divided layout 7140.

  On the other hand, in another layout example 7420, the user designates that the station premises information of the A station and the C station is hidden and the station premises information of the B station is displayed. In this case, the GUI display unit 2230 combines the divided layout 7220 in the station B and the divided layouts 7310 and 7330 between the stations. Since the station premises information of the B station is designated to be displayed, the division layout 7120 between the stations is also combined between the A station and the B station (example 2). The combination result of the divided layouts in this case is a train diagram layout of divided layout 7310−divided layout 7120−divided layout 7220−divided layout 7330−divided layout 7340.

  Next, the GUI display unit 2230 adds a drawing element straddling the divided layout to the train diagram layout created up to step 1130 (1140). In this case, the GUI display unit 2230 has drawing elements that straddle the divided layouts (= the divided layout straddling identification information 5215 is a drawing element that straddles the divided layouts) for each divided layout constituting the train diagram layout. Is drawn). Since drawing elements straddling the divided layouts are drawn on the train schedule layout that has already been generated, even if the divided layout changes, for example, the drawing elements are also divided along with the length of the divided layout. There is no such thing as being done.

  Note that the coordinate values of the drawing elements straddling the divided layouts are stored as coordinate values in the two-dimensional coordinate system in the target divided layout, not the coordinate values in the two-dimensional coordinate system of the train diagram layout as in the other drawing elements. Stored in the unit 201. Therefore, in order to draw the drawing elements straddling between the divided layouts on the train diagram layout, it is necessary to convert the coordinate values to the two-dimensional coordinate system of the train diagram layout. As this calculation process, for example, a process of adding the difference in coordinate values between the coordinate system of the target divided layout and the coordinate system of the train diagram layout to the display coordinates of the drawing elements straddling the divided layouts, etc. Can be assumed.

  On the other hand, the display coordinates of the drawing elements are in the coordinate system of the corresponding divided layout. For example, even if the display status of the station premises area is changed, the display coordinates only change with the divided layout. No processing is required. Therefore, high-speed redisplay processing can be realized even if the display status of the station premises area is changed.

  Subsequently, the diagram display unit 2220 uses the current position of the vertical and horizontal scroll bars arranged in the drawing screen of the output device 206 as information on the user work area in the drawing screen, and the GUI of the information processing apparatus. It is acquired from the function (the GUI display data 2150) (1150). As a method for a user to operate a display range of a train diagram layout such as a train diagram, a method using a scroll bar or a scroll box is common. For example, among the two vertical and horizontal dimensions in the scroll box, one dimension indicates the distance relationship, and the other dimension indicates the flow of time. For example, there is a setting example in which the time axis corresponds to a time zone for 24 hours as a standard, and the deployment start time is before the time of the first power generation vehicle. In this case, for example, if 4:30 is set as the development start time, the end is 4:30 on the next day. In addition, the station name is displayed on the distance axis, and all stations in the corresponding line area are displayed.

  Further, the diagram diagram display unit 2220 acquires drawing element data such as each divided layout included in the user work area acquired in step 1150 and displays the data in the work area (1160).

  The steps 1150 and 1160 will be further described with reference to FIG. In general, there are many cases where the train information described in the train diagram layout is from 100 to 1000. If such a train diagram layout is displayed on the screen, all train information is displayed on one screen. In that case, depending on the number of diamonds, it may be difficult to see the train information on the screen or the drawing elements may overlap. In order to prevent such a situation, the user displays only a part of the area from the entire train diagram layout 8210. This part of the area becomes the work area 8110.

  In this step 1160, the position of the user's work area in the drawing of the train diagram layout using the position of the scroll bar acquired in the step 1150 and the setting of the display magnification obtained from the GUI display data 2150. The size is specified, and the drawing element data included in the work area in the entire train diagram layout is acquired and displayed.

--- Display processing associated with events ---
The display process described above is a display process in the system 200 when the user starts the train diagram display process program. On the other hand, in addition to the initial display process at the time of activation, a redisplay process associated with a GUI event may be performed. At this time, a train diamond layout redisplay process is performed.

An example of such a GUI event will be described with reference to FIG. For example, when the user selects the area 9310 of the station A on the GUI and displays or hides the station premises information, a display change event of the station premises area occurs. Further, for example, the user clicks the scroll bar 9210 along the horizontal axis, move the scroll bar 9210, when moving the work area, an event occurs to change the position of the working area. For example, when the user changes the time information on the GUI menu 9140, an event for changing the diagram data occurs. Further, for example, when the user selects a train information line (line) 9410, a line highlight setting event occurs.

  Re-display processing associated with the above-mentioned station change area display change event, diagram data change event, and work area position change event will be described with reference to FIG. In the case of a station change area display change event, a display process is executed again from the above-described station acquisition area display / non-display status acquisition step (step 1120), and the display is redisplayed. The train diagram layout corresponding to the display / non-display of the area can be output. Here, when there is a display event in the station premises area, each processing time when the train diagram layout is re-laid out by the conventional method and when the display is re-displayed according to the present embodiment is an example of the processing time. It shows with the graph and table | surface of a comparative figure (FIG. 12). Comparing the two, it can be seen that the processing time can be reduced by 94% or more compared to the prior art by applying the method of the present embodiment.

  The diamond data change event is an event that occurs when the user changes the train information in the GUI display data 2150. For example, in the example shown in FIG. 10, an event that occurs when the user clicks the menu 9140 and changes the departure time of the train in the displayed dialog box can be assumed. When this event occurs, it is not necessary to display the drawing element calculated for the train information before the change, so the drawing element management unit 2240 deletes the corresponding drawing element from the drawing element table 5210, for example. (10130), and the work area is displayed. In addition, after deleting the corresponding drawing element from the drawing element table 5210, the display process is executed again from the “drawing drawing elements in each divided layout” (step 13150) process, so that the work area can be redisplayed. . In order to display the target train after the change, any one of the diagram display unit 2220, the GUI display unit 2230, and the drawing element management unit 2240 calculates a drawing element of the target train information (10160), and directly Drawing in the work area (10180). As a method for identifying a drawing element drawn directly in this work area and a drawing element drawn in a divided layout, for example, there is a method in which identification information for setting the work area is included in the information in the drawing element table 5210. . Alternatively, a method of managing a drawing element table for a work area on a memory as a separate table can be assumed.

  Note that the drawing elements calculated in step 10160 are not added to the drawing element table 5210 until the change of train information is confirmed. The reason for not adding will be described below.

  For example, there is a drag-and-drop operation or the like in which the user may continuously change the train information by operating the GUI. In this case, it is necessary to continuously perform the redisplay process for each change until the user confirms the change of the train information (for example, pressing a button for confirmation). If the display processing after step 13150 is performed every time there is a change, the system 200 also performs display processing of the entire train diagram layout while displaying the corresponding train information and its drawing elements, so that the drag operation is performed. There is a problem that the response becomes worse.

  Therefore, when such continuous train information changes are made, display processing such as generation of drawing data and divided layouts, setting to the drawing element table 5210, etc. is performed at the start of change and change confirmation in order to solve the above problems. Only when When there is a change other than when the change is started and when the change is confirmed, the system 200 displays the drawing element in the work area, for example. By not performing the display process other than at the time of starting the change and confirming the change, the drawing elements related to the train information in which the change has occurred are not calculated for each change and added to the drawing element table 5210, etc. Drawing elements are drawn in the area (10180), and the processing performance can be improved.

  On the other hand, when the change is confirmed, for example, when the drag and drop operation ends, a drawing element for the train information for which the change is confirmed is added to the drawing element table 5210 and the like, and the work area setting of the drawing element is set. The identification information is cleared, and the continuous change display process is terminated (10170).

On the other hand, the work area change event is an event that occurs when the user changes the position of the work area with respect to the train diagram layout or the like using the horizontal axis scroll bar or the vertical axis scroll bar. In this case, since only the position of the work area that the user wants to display is changed, the system 200 performs the display processing by “acquiring the position of the work area” (1150) and “the train diagram layout corresponding to the work area”. The work area can be displayed by executing “acquire and display” (1160).

  In addition, the flow of the re-display control process accompanying the line highlight change and animation setting change event of the train diagram layout is shown in FIG. Here, for example, when an animation is displayed on the drawing of the train diagram layout (= for example, a streak in the train diagram layout blinks), the target drawing element is continuously changed, and the drawing element is displayed each time the change is made. Will be.

  In addition, regarding the highlight of the train line in the train diagram layout, when changing the train information (for example, changing the train time, copying the train) on the GUI, the user selects the train line to be changed. The system 200 makes it easy for the user to identify the change target by highlighting the train line selected by the user.

  In the present embodiment, as a method of displaying the stripe highlight or animation, a process of drawing and displaying a corresponding drawing element in the work area is employed instead of creating and displaying a train diagram layout. . The reason is shown below. For example, when an animation is displayed, the drawing elements are continuously changed as described above. Therefore, if the train diagram layout is changed with each change, the display process becomes heavy. Note that highlight drawing elements are used only at the moment when a streak is selected, and the user frequently changes the selection target train by a GUI operation. To do. Therefore, if the train diagram layout is changed by highlighting every time it is changed, the display process becomes heavy.

  The above problem can be solved by drawing highlight change and animation display processing directly in the work area. The system 200 calculates streak highlight or animation drawing elements (11120) and draws the drawing elements in the work area (10180).

  Although the best mode for carrying out the present invention has been specifically described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  According to this embodiment, even if the layout size of the train diagram changes due to a change in the display status of the station premises area, the size of each divided layout does not change, and the coordinates of each drawing element relative to the divided layout change. Etc. does not occur. In other words, even if the display status of the station premises area is changed, no re-layout process is required, so that high-speed processing can be realized with respect to the GUI processing of the train diagram. Further, even when there is a situation where train information is continuously changed, such as drag and drop, only the drawing elements for the changed train information are laid out, so that the GUI processing of the train diagram can be performed at high speed.

  Therefore, even when the drawing situation of the station premises information displayed on the layout of the train diagram is changed, the GUI processing related to the train diagram and the station premises information can be executed at high speed and without any problem on the display.

At least the following will be clarified by the description of the present specification.

  Further, in the train diagram display processing method, the information processing apparatus uses the vertical and horizontal scroll bar positions in the drawing screen on the output device as information on the user work area in the drawing screen, and the GUI function of the information processing apparatus. It is good also as performing any one of the said process B-the process E about the drawing element contained in the user work area acquired here.

  Further, in the train diagram display processing method, when the information processing apparatus receives an operation of moving the drawing position of the drawing element of each layout already drawn by the output device by the input device, other than the corresponding drawing element The coordinates of the drawing element at which the drawing position on the layout transitions in accordance with the moving operation is temporarily deleted in the storage unit without changing the drawing element of the display coordinate data registered for the drawing element. Is obtained from the GUI function, the coordinates are stored in the work storage area, and when the input device receives a position fixing instruction, the coordinate value of the storage area is set as the display coordinates of the drawing element in the corresponding layout. You may do it.
