Description

  Embodiments described herein relate generally to a diamond creation apparatus and a diamond creation method.

In general, a railway operating company inputs data such as the departure and arrival times at each station of a train and the distance (km distance) between adjacent stations on a diagram creation device, and then creates this diagram data as an operation diagram. (Hereinafter referred to as “diagram diagram”) is displayed on the screen to manage train operation. For example, the diagram is represented in a graph form in which the distance from the first station (reference station) is plotted on the vertical axis, the time is plotted on the horizontal axis, and the names of traveling stations are arranged on the vertical axis in consideration of the distance between stations. One train is represented by a single line on the diagram. If the starting station of the down train is placed at the top, and the coordinate axis is placed so that the distance increases downward and the time increases to the right with this point as the origin, the down train goes down and the up train goes to the right. Draw a rising line. The slope of the line represents the speed of the train. The faster the train, the larger the slope of the line, and the horizontal line (slope 0) represents that the vehicle is stopped.
In addition, when creating an operation diagram in a railway network having a line section where there are many branches, a device has been devised to draw it so that it can be put on one screen including the branch line section.

Japanese Patent No. 3544328

  However, the diagram diagram notation in the prior art is unique to railway operators, and when creating a railway operation diagram with a line with many branches, not only simply drawing lines, It becomes complicated such as skipping a certain section.

  In addition, when a new line is created or when a connection with another company's route is realized, it is necessary to start consideration for entering the new line, but due to the complicated notation above, It will be reviewed from the arrangement. This is because the diagram diagram description method on paper is followed, but a new diagram notation and creation method has not been proposed in the computerized diagram system.

  Furthermore, it is extremely difficult to create a diamond with the conventional diamond notation / preparation method considering the overseas railway situation. For example, in Europe, railway management separates the lower (infrastructure) management and upper (operation / operation) organizations and separates the lower and upper accounts. In particular, in the case of Germany, there are cases where not only the upper and lower parts are separated but also open access is introduced and there are a plurality of upper organizations. From this mechanism, the entry of new operating companies is permitted, and the track can be used freely. European railways, unlike mass transport between large cities in Japan, operate trains by freely selecting routes on tracks stretched around like a mesh for the purpose of transport between regional bases. There is a high need to do it. For this reason, it is required for a diamond system that a single resource called a track can be effectively used by a plurality of operating companies, and the selection and management of operation routes that tend to be complicated can be simplified. However, the conventional diamond notation and creation method is not suitable because it is intended for the case where the vehicle travels repeatedly on a predetermined route as in Japan.

  Accordingly, in view of the above-described problems of the prior art, the present invention displays a diagram with high visibility and operability, and a diagram creation device and a diagram creation method capable of easily creating an operation diagram in a railway network in which many branches exist. The purpose is to provide.

  A diagram creation device according to an embodiment of the present invention includes a database, a processing device, and a display device.

  The database includes a line master that stores the name of a line within a railway network including a plurality of lines and a line code for identifying the line as line data, and a reference code in the same line together with the line code. Station order master code that stores the station order code indicating the order of the station, the station name, and the relationship of the distance from the reference station as station order data, and the line code, station order code, and branch destination for branch stations belonging to multiple line sections A branch master that stores the relationship of the line code as branch data.

  The processing device reads line segment data, station order data, and branch data from the database, and creates a diagram that displays station lines and diagrams associated with station names on a two-dimensional plane composed of a time axis and a distance axis. The display device displays a diagram generated by the processing device.

  The processing device includes means for displaying in a diagram a station line in which the line name, the station name of each station included in the line area, and the distance from the reference point of each station are displayed in parallel in the time axis. When the branch button is pressed, means for displaying in the diagram the branch button associated with the other branch line in the vicinity of the station line corresponding to the branch station belonging to the other line section The station order data and branch data are read based on the branch line code of the branch destination, and a part of the station line related to the line area displayed in the diagram is a branch station belonging to another line area starting from the branch station And means for switching to a subsequent station line for display.

The station order master 102 stores the relationship between the line code, the station order code indicating the order from the reference station in the same line, the station name, and the distance from the reference station (the station order code 1 or the cumulative distance from a certain reference). It is a table memorize | stored as station order data. Table 2 below shows a specific example of the station order master 102, and station order codes are assigned in ascending order from the first station to each line section.

The branch master 103 is a table that stores, as branch data, a relationship between a line code, a station order code, and a branch destination line code related to branch stations belonging to a plurality of line sections. Table 3 below shows a specific example of the branch master 103.

Here, if the display order from the station line to the other line is positive, place it on the station order code ascending side (bottom of the diagram), if it is negative, station order code descending side This means that it is placed on the upper side of the diagram. Further, when the branch destination line direction is 1, the station order code is in the ascending order direction station, and in the case of -1, the station order code is in the descending order direction station.

  The line section determination unit 105 is a program that refers to the line section master 101 and determines a line section code related to a target line section that is a target of display / creation of a diagram showing the relationship between kilometers and time. The line code determination method includes a method of reading data of the line master 101 and allowing the user to select from a list displayed on the screen, or a method of directly inputting the line code.

It is a program for displaying a diagram creation screen including a diagram diagram in which a branch button in which a branch destination line code and a branch line line direction are associated is provided in the vicinity of a station line related to a branch station in the figure.
Further, the diagram display processing unit 108 arranges the branch buttons with respect to the station line of the branch station included in the branch data (display order from the station line to the other line area) and from the branch station in the other line area to the adjacent station. Based on the direction flag (branch line direction), the arrangement of the branch button and the station order code associated with the branch button are determined, and a diagram is created and displayed.

  When the branch button is pressed on the diagram creation screen, the line segment switching unit 109 selects a part of the station line related to the target line segment in the diagram based on the branch destination line code as the starting point of the other branch station. It is a program that switches and displays the station lines after the branch station belonging to the line district. Specifically, the branch destination line code, station order code and branch destination line direction associated with the branch button when creating the diagram are output to the diagram display processing unit 108, and the master data is reloaded. Switch the line section.

The diagram data creation unit 110 analyzes the coordinates of the diagram drawn with continuous lines in the diagram diagram on the diagram creation screen, and the train line code, departure station, arrival station, departure time and It is a program for creating diagram data indicating the relationship between arrival times.
Further, when the diagram based on the created diagram data is changed on the diagram creation screen, the diagram data creation unit 110 creates new diagram data based on the modified diagram and updates the diagram data storage unit 104. .

  FIG. 2 is a diagram illustrating a hardware configuration example of a computer applied to the diagram creating apparatus illustrated in FIG. As shown in the figure, the diagram creation device includes a CPU (Central Processing Unit) 401, a ROM (Read Only Memory) 402, a RAM (Random Access Memory) 403, an input / output interface 404, a system bus 405, an input device 406, It comprises a display device 407, an auxiliary storage device 408, and a communication device 409.

FIG. 3 is a route diagram showing a railway network that is a target of creation of diagram data in the diagram creation device shown in FIG. In this railway network, three lines of an α line area, a β line area, and a γ line area branch from the B station. FIG. 4 is a diagram showing a specific example of a diagram that the conventional diagram creation device creates and displays for the route shown in FIG. As shown in the figure, in many cases, different line segments are often combined and described in one sheet on a diagram. This is an idea to indicate the branch line section in one figure.
However, if a diagram (drawing of each train on the diagram) is drawn on the computer using this diagram diagram representation, the drawing and operation of the branch portion will be complicated. In addition, it is very difficult to realize a unified system regardless of the railway company because it is influenced by the circumstances of each railway company.

For example, if there is a train that goes from the β line section X station to the γ line section Z station via the B station, the diagram shown in the diagram of FIG. 4 is obtained. A diamond must be drawn so as to skip the α line and β line sections below B station (parts connected by dotted lines). In order to connect with a dotted line, link information must be input separately.
On the other hand, the diagram creating apparatus 1 according to the embodiment of the present invention can draw a diagram extending over a plurality of line sections with continuous lines. Hereinafter, the diagram creation process and the line segment switching process in the diagram creation apparatus 1 will be described in detail.

FIG. 5 is a flowchart showing a specific example of the diagram creation process in the diagram creation apparatus shown in FIG.
In S <b> 501, the line segment determination unit 105 refers to the line segment master 101 and determines a line segment code related to a target line segment that is a target of display / creation of a diagram showing the relationship between kilometer and time.
In step S <b> 502, the station order data reading unit 106 reads station order data from the station order master 102 using the line section code determined by the line section determination unit 105 as a key.

  In S503, the station order data reading unit 106 determines whether there is unprocessed station order data for the target line section. If it is determined that there is unprocessed station order data (S503: Yes), the process proceeds to S504. On the other hand, when it is determined that there is no unprocessed station order data (S503: No), the process proceeds to S511.

  In step S <b> 504, the branch data reading unit 107 reads branch data from the branch master 103 using the line section code and station order code included in the station order data read by the station order data reading unit 106 as keys. At this time, branch data is read in ascending order of display designation order (display order from the station line to the other line section) of the branch master 103 corresponding to the station order code.

  In S505, the diagram display processing unit 108 determines whether branch data exists. If it is determined that branch data exists (S505: Yes), the process proceeds to S506. On the other hand, when it is determined that there is no branch data (S505: No), the process returns to S502.

  In step S506, the diagram display processing unit 108 determines whether a branch check box has not been created. If it is determined that the branch check box has not been created (S506: Yes), a branch check box is created (S507). On the other hand, if it is determined that the branch check box has been created (S506: No), the process proceeds to S508.

In S508, the diagram display processing unit 108 determines whether or not the display order on the other line section is a positive value. Here, when it determines with a positive value (S508: Yes), it progresses to S509. On the other hand, when it determines with a negative value (S508: No), it progresses to S510.
In S509, the diagram display processing unit 108 creates a branch button below the branch station.

In S510, the diagram display processing unit 108 creates a branch button above the branch station.
In S511, the diamond display processing unit 108 reads the registered diamond data from the diamond data storage unit 104 and develops it on the memory.
In S512, the diagram display processing unit 108 draws and displays a diagram.

FIG. 6 is a flowchart showing a specific example of the line segment switching process in the diagram creating apparatus 1 shown in FIG. 7 to 12 are diagrams showing specific examples of the line section switching process.
In step S601, the diagram display processing unit 108 determines whether the branch check box displayed on the diagram creation screen is ON. ON / OFF of the branch check box is a switch for determining whether or not to display a branch button when there is a branch around the station line of the branch station. If it is determined that the branch check box is ON (S601: Yes), the process proceeds to S602. On the other hand, if it is determined that the branch check box is OFF (S601: No), the process proceeds to S603.

  In S602, the diagram display processing unit 108 displays a branch button near the station line of the branch station on the diagram creation screen. Assuming that the branch check box is initially OFF, the diagram drawing area when the α line section is displayed is as shown in FIG. When the branch check box displayed between the station name and the kilometer is turned ON, a branch button is displayed around the α line B station where the branch exists as shown in FIG. Here, a branch button is displayed based on the branch master 103 shown in Table 3 above, and when the display order to other line sections is a negative value, branch to the station code descending side (upper diagram) When a button is arranged and the display order to other line sections is a positive value, a branch button is arranged on the station code ascending order side (lower side of the diagram).

  In S603, the line section switching unit 109 determines whether or not the branch button is pressed in the diagram creation screen. If it is determined that the branch button has been pressed (S603: Yes), the process proceeds to S604. On the other hand, when it is determined that the branch button is not pressed (S601: No), the process proceeds to S605.

  In S604, the line section switching unit 109 outputs the branch destination line code, the station order code, and the branch destination line direction associated with the pressed branch button to the diagram display processing unit 108. Accordingly, the diagram display processing unit 108 reads the master data from the station order master 102 and the branch master 103 again using the station order code and the branch destination line code as keys. The master data reading process is the same as that in the flowchart of FIG. 5 described above, but the station order master data read from the station order master 102 is sufficient only from the branch station to the branch destination line direction.

In S605, the diagram display processing unit 108 switches a part of the diagram display area related to the target line section in the diagram to the diagram display area related to another line section from the branch station as a starting point based on the branch destination line section code. To display.
For example, as shown in FIG. 9, in the state in which the α line section is displayed, three branch buttons at station B appear. Then, when you click the branch button for “γ line district Z station direction” on the station order code ascending side (bottom of the screen), as shown in FIG. Switch to γ-ray section. Moreover, the branch button is recreated about the γ-ray by reading the branch master 103 again as the γ-line B station. In addition, as shown in FIG. 11, when the branch button of the station B code appears in the state where three branch buttons of the station B appear, when the “β line section X station direction” branch button is clicked, 12, the station order code descending side (upper side of the screen) is switched to the β line section from the B station.

  In S606, the diagram display processing unit 108 determines whether or not the branch check box displayed on the diagram creation screen is OFF. If it is determined that the branch check box is OFF, the process proceeds to S607. On the other hand, if it is determined that the branch check box is ON, the process proceeds to S608.

In S <b> 607, the diagram display processing unit 108 returns the branch button displayed near the station line of the branch station on the diagram creation screen to non-display.
In S608, the diagram display processing unit 108 determines whether or not the line section on which the train travels has been determined based on the presence or absence of a line section switching request. Here, when it is determined that the line section has been confirmed, the process proceeds to S609. On the other hand, when it is determined that the line section is not fixed, the process returns to S601.

In step S <b> 609, the diagram display processing unit 108 accepts input from the user for the line segments displayed on the diagram, and draws a diagram.
In step S610, the diagram display processing unit 108 determines whether drawing of a diagram is completed on the diagram creation screen. For example, it is determined based on whether or not a completion button (not shown) is pressed. If it is determined that the drawing of the diagram is completed, the process proceeds to S611. On the other hand, if it is determined that it is not completed, the process returns to S609.

  In S611, the diagram data creation unit 110 analyzes the coordinates of the diagram drawn by continuous lines in the diagram diagram of the diagram creation screen, and the train line code, departure station, arrival station, The diagram data indicating the relationship between the departure time and the arrival time is created and registered in the diagram data storage unit 104. When the diagram related to the registered diagram data has been changed, the diagram data is updated. For example, as in the example shown in FIG. 4, if there is a train that goes from the β line X station to the γ line Z station via the B station, it becomes a diagram diagram as shown in FIG. A simple drawing that doesn't feel a branch can be realized.

  As described above, according to the diagram creating apparatus 1 according to the present embodiment, a branch button (branch line section display button) is prepared at a station where a branch line section exists, and the station display unit is pressed by pressing the branch button. Buttons with branch line names appear on the up and down sides respectively. Then, when a button with a branch line section name is pressed, the display is switched to a line section that is newly selected from there. By using this expression, even if there is a branch, a diagram can be expressed like a simple straight line, and diagram drawing and operation on the diagram can be realized by simple operations.

  In addition to routes that have already been branched or boarded, it is structured so that it can not be entered, and even if it is a zone that is considering entering in the future, it is possible to consider entering only by correcting the master data .

  Moreover, the drawing of the diamond itself can be handled as one continuous line section around the branch station, and can be drawn by a simple diagram theory that draws a line between conventional stations. In particular, when creating a train diagram on a route that stretches around like a mesh, by switching the branch and expressing it as a single route, the continuity of streaks is lost and intermittent Therefore, it is possible to realize continuous and highly visible diamond display.

  In the following, the difference from the conventional diagram display will be described supplementarily. FIG. 14 is a route diagram showing a railway network that is a target of creation of a diagram in the diagram creation device shown in FIG. Here, there are five routes stretched around like a mesh. FIG. 15 is a diagram showing a specific example of a diagram displayed on the railway network shown in FIG. 14 by a conventional diagram creation device. Here, consider the case of creating a train diagram that travels like a thick line in the railway network as shown in FIG. With traditional Japanese drawing and expression methods, all routes will be posted on the same screen and paper, or a route will be decided to some extent and only the narrowed routes will be displayed to create a diagram. . However, with this drawing rule, when a route is freely selected and a route is set, the continuity of the diagram is lost as shown in FIG. 15, resulting in a screen with poor visibility and operability.

  On the other hand, FIG. 16 is a diagram showing a specific example of a diagram displayed on the railway network shown in FIG. 14 by the diagram creating apparatus shown in FIG. For example, assuming that the H line is displayed at the start, even if the complicated route shown by the thick line in FIG. Thus, it is possible to realize a diagram drawing by a continuous line having higher visibility than that of FIG.

  As mentioned above, although several 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.
