Description

  The present invention relates to a transportation information display system that acquires operation data from a train operation management system and displays a streak screen or the like.

In recent years, transportation information display systems are often built using Web technology. By using the Web technology, it is not necessary to install dedicated software in each client terminal, and transport information can be browsed using a general-purpose Web browser.
In addition, as long as the transportation information display system can be accessed via a network such as the Internet, the transportation information can be browsed even in a remote place, and transportation information can be provided in a wider range.

As for the display of the streak image in the conventional transportation information display system, daily plan diagram information is acquired from the operation management system, and so-called streak image data, which is a diagram, is created.
The image data is displayed as a web page. (For example, refer nonpatent literature 1).
However, the created diagram data is a raster image such as BMP or JPEG, and the created diagram is only the planned diagram.

In FIG. 1, an operation management system 1 that manages the operation of a train is connected to a server device 3 that provides information to a client terminal 5 via a LAN 2. A plurality of client terminals 5 that display information acquired from the server apparatus 3 are connected to the server apparatus 3 via a network 4 such as an intranet or the Internet.

  The server device 3 includes an interface unit 7 (hereinafter abbreviated as I / F unit 7) that acquires the diagram data 6 that is operation data from the operation management system 1, and the SVG from the diagram data 6 acquired by the I / F unit 7. It has a streak screen data generation unit 9 that generates streak screen data 8 described in a format, and a web server 10 that provides the client terminal 5 with web data that incorporates the streak screen data 8 in the HTML format.

  Further, the client terminal 5 has a web browser 11 for displaying the web data received from the server device 3.

The operation of the transportation information display system having the above configuration will be described below.
First, the I / F unit 7 receives the diagram data 6 from the operation management system 1. The schedule data 6 shows the schedule of operation on the day in time. The schedule to be received before the start of work, the schedule of train operation results in time, results of operation arrangements such as suspension, results of operation arrangements, etc. In consideration of the above, it includes a prediction diagram that shows a future operation plan in time, and the result diagram, the result of operation arrangement, and the prediction diagram are received from the operation management system 1 in a timely manner.
The diagram data 6 is converted to the streak screen data 8 written in the SVG format in the streak screen data generation unit 9 and provided to the client terminal 5 via the Web server 10.

Next, the internal operation of the streak screen data generation unit 9 in the transportation information display system according to Embodiment 1 of the present invention will be described in more detail with reference to the flowchart of FIG.
First, as an initialization process, initial drawing information such as coordinate information is generated in the internal memory from the diagram data 6 (step S21). Subsequently, an end process determination is made as to whether an end signal such as OS end or power off has been received. If it is determined to end, the process ends. If not, the process proceeds to step S23 (step S23). S22).

Next, when the diagram data 6 is updated by a performance diagram, a result of operation arrangement and a prediction diagram (step S23), the internal drawing information is updated (step S24).
Next, the time for performing the periodic processing is checked (step S25), and if it is determined that the time is right, the streak screen data 8 is generated in units of station sections and time zones for each predetermined line section. Then, the streak screen data 8 is output (step S27). After the streak screen data 8 is output, the process returns to the end process determination in step S22 again to continue the operation.

  The created streak screen data 8 is converted to Web data by the Web server 10 and provided to the client terminal 5 via the network 4. In the client terminal 5, a streak screen is displayed by the Web browser 11.

  When the client terminal 5 accesses the Web server 10 via the network 4 by the Web browser 11, the Web server 10 returns Web data including the latest stripe screen data 8 to the client terminal 5. The client terminal 5 displays Web data using the Web browser 11.

FIG. 3 is a diagram showing a display example of Web data on the Web browser 11 shown in FIG.
In FIG. 3, the entire streak screen has an operation unit 30 for switching the displayed lines, a train number designation unit 40 for designating a specific train and displaying a schedule time, and an implementation line generated based on the implementation schedule and the actual schedule, It consists of a streak screen display unit 50 on which a diagram such as a result streak is displayed.

The entire operation unit 30 includes a line segment switching unit 31 that switches a line segment to be displayed, a time zone switching unit 32 that switches a time zone to be displayed, and a line type switching unit that switches the type of stripes to be displayed, such as implementation lines and actual lines. 33, an up / down type switching unit 34 for switching the display line up and down, a scale switching unit 35 for expanding and reducing the display range, a reference button 36 for sliding the display range at a reference time, and updating information to be displayed. And an update button 37.
Moreover, the train number specification part 40 has the train number input part 41 which inputs the train number of the arbitrary train which browses time information, and the execution button 42 which performs the display of time information.

The streak screen display unit 50 includes a streak screen 51, a streak region 52, a station name region 53, a time region 54, and a base 55, and a horizontal scroll bar 56 that scrolls the display screen in the time direction, and scrolls the display screen in the direction of the station. A vertical scroll bar 57 is provided.
Here, the streak screen display unit 50 displays the streak screen data 8 described in the SVG format on the Web browser 11, and the operation unit 30 and the train number designation unit 40 are described in the HTML format.

The operation of the display screen in FIG. 3 will be described below. The operation of the line section switching unit 31, the time zone switching unit 32, and the train number designation unit 40 will be described in the second embodiment.
First, when the type of streak to be displayed is specified by the streak type switching unit 33, the streak displayed in the streak area 52 is switched. In the streak screen 51 shown in FIG. 3, the execution streak and the actual streak are displayed. In addition to this, for example, there are only implementation lines and only performance lines.
When the direction of the stripe to be displayed is designated by the vertical type switching unit 34, the stripe displayed in the stripe area 52 is switched. In the streak screen 51 shown in FIG. 3, vertical streaks are displayed. In addition, for example, there are only uplink and downlink only.

When the display scale is designated by the scale switching unit 35, the streak screen 51 is displayed according to the scale. In FIG. 3, it is displayed on a scale on which two hours are displayed on the screen. When this is displayed for one hour, that is, when the scale is doubled, the scale of the streak screen 51 is switched accordingly. A display example at the time of enlargement is shown in FIG.
At this time, the width and height of the streak area 52, the station name area 53, and the time area 54 do not change, and the character sizes of the station name area 53 and the time area 54 do not change, and only the display contents of the streak area 52 are reduced.

When the reference button 36 is pressed, the screen is slid so that the reference time on the screen (or the current time when the current time is included) comes to a fixed position.
When the update button 37 is pressed, the latest data of the streak screen data 8 is acquired from the server device 3 and displayed.
It is also possible to adopt a mechanism for acquiring the latest data from the server device 3 at regular intervals without pressing the update button 37.

  When the horizontal scroll bar 56 is operated, the stripe area 52 and the time area 54 are scrolled in the horizontal direction, and when the vertical scroll bar 57 is operated, the stripe area 52 and the station name area 53 are scrolled in the vertical direction. .

Here, no data communication with the server device 3 occurs in the operation of the streak type switching unit 33, the vertical type switching unit 34, the scale switching unit 35, the reference button 36, the horizontal scroll bar 56, and the vertical scroll bar 57, and the streak screen. The operation is performed by processing in the client terminal 5 that has received the Web data including the data 8.
When the window size is changed, the size of the streak screen 51 changes dynamically according to the window size.

Here, the streak screen data 8 is described in, for example, the SVG (Scalable Vector Graphics) format.
The SVG format is a language for describing XML-based vector images. Since vector images handle images as a collection of figures such as lines and planes instead of a collection of points, an optimal display is possible according to the viewing environment. Is possible.

Hereinafter, the internal structure of the SVG format will be described.
FIG. 5 is a diagram showing an example of dividing the area of the streak screen 51 shown in FIG.
In FIG. 5, first, a character string of a background portion such as a station name and a time character is taken out from the entire streak screen 60 and defined as a character area areaST.
Next, the entire streak screen 60 is divided into blocks that can be displayed on the screen, and each of the divided lines is divided into block blocks (0, 0), block (1, 0),..., Block (m + 1, 0) in the column direction. Define block block (0, 0), block (0, 1),..., Block (0, n + 1) in the row direction.

  Here, adjacent blocks of 2 rows and 2 columns are defined as one area, which are defined as area (0, 0), area (1, 0),... Area (m, n). Each arbitrary area (i, j) is area (i, j) B which is an area having a background portion such as a station line or a time line as drawing information, and area (i, j) which is an area having a stripe as a drawing target. j), and other layers defined as area (i, j) M, which is an area having symbols as drawing targets.

  In addition, for area (i, j) having a streak as a drawing target, area (i, j) UP, which is an area having an ascending execution streak as a drawing target, and an area having ascending actual streak as a drawing target. Defined as an area (i, j) UR, an area (i, j) DP which is an area having a downstream implementation line as a drawing target, and an area (i, j) DR which is an area having a downstream actual line as a drawing target Is divided into layers.

The streak screen 51 in which the area is defined in this way is described in the SVG format. An example is shown in FIGS.
FIG. 6 is a diagram showing portions related to the function definition 70 and the drawing definition 71 in the SVG format in which the streak screen data 8 of FIG. 1 is described.
FIG. 7 is a diagram showing a portion related to the display description 72 in the SVG format in which the streak screen data 8 of FIG. 1 is described.

The description of this SVG is roughly divided into a function definition 70 describing functions indicating various operations, a drawing definition 71 defining a drawing target in the streak screen 51, and a display description 72 for displaying the drawing definition 71. It consists of three parts.
In the drawing definition 71, first, the positions and sizes of the streak area 71a, the station name area 71b, and the time area 71c are defined, and then the entire streak screen 71d is defined.

The entire streak screen 71d is defined by a set 71e of station names and time characters defined by areaST, a set 71p of area (0,0) 71f and area (1,0), ... area (m, n). .
The area (0,0) 71f includes a background drawing target set 71g defined by area (0,0) B, a stripe set 71h defined by area (0,0), and area (0,0). ) It consists of a set 71o of symbols defined by M.
Here, the streak set 71h is composed of an upstream streak set 71i and a downstream streak set 71n, and the upstream streak set 71i is an implementation streak set 71j composed of the implementation line 171k and other implementation lines 2 to 2n 71l. And a set 71m of performance lines.

  In the display description 72, the background 72a of the streak screen 51 is first displayed, and then the streak area 72b, the station name area 72c, the time area 72d, the horizontal scroll bar 72e, and the vertical scroll bar 72f are displayed.

  Due to such an internal structure, when only an upstream execution streak is displayed, area (x, y) UP may be specified in the display description 72 of the streak area 52, so that switching is instantaneously performed regardless of the number of drawing objects. Is possible. The values of x and y are automatically determined by scrolling with the horizontal scroll bar 56 and the vertical scroll bar 57. Since the display target is always in units of areas, the screen scrolling processing speed is constant regardless of the display time width of the streak screen 51.

Further, in the case of performing the enlargement / reduction display of the streak screen 51 by such an internal structure, a function for performing the enlargement / reduction process is prepared in the function definition 70 of FIG. Regardless of the number of objects to be drawn, enlargement / reduction processing can be performed instantaneously.
In the enlargement / reduction process, for example, in the SVG format, enlargement / reduction is performed by setting the enlargement / reduction attributes in the SVG for the streak area 52, the station name area 53, and the time area 54.

However, the streak area 52 is enlarged and reduced both in the horizontal and vertical directions, the station name area 53 is enlarged and reduced only in the vertical direction, and the time area 54 is enlarged and reduced only in the horizontal direction. In addition, for the set of station names and time characters, the display position of the characters is changed instead of using the scaling attribute.
By the enlargement / reduction process using such a function, the enlargement / reduction process shown in FIG. 4 can be performed.

According to the transportation information display system according to Embodiment 1 of the present invention, since the streak screen data 8 is described in the SVG format, the display scale and the display pattern can be changed by one streak screen data 8, The display operation can also be performed instantaneously without depending on the number of objects to be drawn.
Moreover, since the diagram data 6 which is operation data is periodically acquired from the operation management system 1, it is possible to display on the streak screen 51 reflecting the operation results and the results of operation arrangement.
