Description

  The present invention relates to a train operation status display device, and more particularly, a train operation status display that can selectively display a necessary display range from display data stored so as to be able to cover a predetermined operation range. The present invention relates to a display device.

  Although it is desirable to display the train operation status in a horizontally long state in which train passing stations from the start point to the end point of a specific route are arranged in order, it is generally difficult to display them on the display all at once. Some of them are displayed by switching the screen.

  In other words, the station to be located in the center of the display is determined in advance, and the front station area and the rear station area are displayed together around that station, in other words, the screen with a fixed viewpoint is switched and displayed. It was.

  As a specific example, the data to be displayed on the display screen of the display 2 is stored in advance as data corresponding to each of the plurality of display screens to be switched and displayed as conceptually shown in FIG.

  A plurality (n) of data is stored for displaying train operation status display data 1-1 corresponding to stations A, B, and C, and for displaying train operation status data 1 corresponding to stations C, D, and E. -2, train operation status display data 1-3 corresponding to stations E, F, and G, train operation status display data 1-4 corresponding to stations G, H, and I, to nth Display data 1-n are stored in advance.

  The desired display data is selected from these stored data, and the data is read out and displayed on the display screen of the display 2.

  Further, the content of the display screen based on the display data 1-1 is such that the A station display, the B station display, and the C station display are arranged in order as shown in display # 1 in FIG. The display contents when 2 is selected are the C station display, D station display, and E station display arranged in order as shown in display # 2, and the display when display data 1-3 is selected. The contents are arranged such that the E station display, the F station display, and the G station display are arranged in order as shown in display # 3, and are similarly displayed as display # 4.

  In addition, as shown in FIG. 7, the overlap for compensating for the discontinuity (discontinuity) of the screen at the time of switching the display is that the display # 1 and the display # 2 are one station, that is, the C station. In addition to a single station unit, a unit smaller than the station unit is also used. For example, overlapping is performed in a track portion between stations.

  In addition, the magnification of the display screen performed based on data arbitrarily selected from a plurality of display data is set uniformly, and when a wide range of display is desired, the plurality of display data are switched. After the screen is displayed and the currently displayed screen is erased, a screen based on new display data is displayed.

  A conventional train operation status display device stores a plurality of display data formed in units of one display screen, reads out desired data from them, and displays them on a display. Each of the data has an overlapping area in a portion displayed adjacent to each other, and when one display data is formed by defining a large number of display parts, the data for the definition of the display parts overlaps. Redundancy occurs in storage, and there is a problem that data storage media such as an IC memory and a hard disk for data storage cannot be effectively used.

  In addition, since the magnification of the display screen performed based on data arbitrarily selected from a plurality of display data is set uniformly, when a plurality of people view the same display screen, the screen does not feel strange. Although it is desirable to enlarge, there is also a problem that it is difficult to realize it, and that it is difficult to reduce it if necessary.

  Furthermore, when the display screen is switched based on data arbitrarily selected from a plurality of display data, the screen flickers at the time of switching, resulting in confusion of the line of sight for the person viewing the screen. There is also a problem that it causes the eyes to be overloaded.

  As a result of the above problems, there is a risk that the overall price of the train operation status display device will be greatly increased or the usability will be reduced.

  Therefore, according to the present invention, when storing a plurality of display data, the data storage medium such as an IC memory or a hard disk can be used effectively, and the display screen can be enlarged without a sense of incongruity as necessary, and can be arbitrarily selected. It is an object of the present invention to provide a train operation status display device that does not cause screen flickering when the display screen is switched based on the obtained data.

  In order to solve the above-described problems, the train operation status display device according to the present invention employs the following characteristic configuration.

(1) A train operation status display device capable of selectively extracting and displaying a necessary display range from display data stored so as to cover a predetermined operation range,
In a state where the coordinate information is included in the various parts data that forms the train operation status display and is centrally defined, the wrapping paper data that is formed in units of a predetermined range of operation is stored,
A train operation status display device for causing a display device to display based on partial display data extracted by designating a predetermined range of coordinate information in the wrapping paper data.

  (2) In the display display performed based on the partial display data, the contents of the memory stored corresponding to the wrapping paper data are output as copy data to the display device of the graphic display device (1) ) Train operation status display device.

  (3) Extraction of partial display data executed by designating a predetermined range of coordinate information in the wrapping paper data is a shear coordinate conversion in which movement, rotation, left-right reversal, enlargement and reduction can be expressed by matrix operations. The train operation status display device according to the above (1) or (2), which is performed using a certain affine transformation means.

  (4) The train operation status display device according to any one of (1) to (3), wherein the display data is stored so as to cover an operation range from a start point to an end point of a train route.

  (5) The display data is for partial display obtained by selecting a specific route from a plurality of data stored so as to cover the operation range from the start point to the end point of each of the plurality of train routes. The train operation status display device described in (4) above, which is data.

  (6) The train operation status display device according to any one of (1) to (5), wherein the various component data is formed of pattern data representing tracks, traffic lights, train number windows, and the like.

  (7) The above-mentioned various parts data is formed by including the attribute information of the parts, the picture data formed by the picture data representing the tracks, traffic lights, train number windows, etc. ) The train operation status display device described in any of the above.

  (8) The train operation status display device according to (7), wherein the attribute information includes information for associating display control information reflecting the status of the site with the component.

  In the conventional train operation status display device, each of a plurality of display data has an overlapping area in a portion displayed adjacent to each other. In the present invention, one display data is stored in a number of display components. When defining and forming the display components, the display components are centrally defined, so there is no redundancy in data storage, and the data storage medium such as an IC memory or hard disk for data storage can be used effectively. .

  Further, the magnification of the display screen performed based on data arbitrarily selected from a plurality of display data is copied to the display device which is a graphic display device from the contents of the memory stored corresponding to the wrapping paper data. Since the data is output as data, a plurality of people can enlarge the screen to see the same display screen, and can perform reduction as necessary without any sense of incongruity.

  Furthermore, since the display screen switching performed based on data arbitrarily selected from a plurality of display data is performed by a double buffer method having a front viewport and a back viewport, the screen may flicker at the time of switching. In addition, the person on the side of the screen is not confused with the line of sight and does not place an excessive burden on the eyes.

  Therefore, according to the present invention, when storing a plurality of display data, it is possible to effectively use a data storage medium such as an IC memory or a hard disk, and the display screen can be enlarged without a sense of incongruity as necessary. It is possible to provide a train operation status display device that does not cause screen flickering when the display screen is switched based on the selected data.

  An embodiment of the present invention will be described as [Embodiment 1] with reference to FIGS. In addition, this example is a train operation status display device configured to display a train operation status in units of specific routes from a wide train management area composed of a plurality of routes. This is an example in which the present invention is applied.

  A large number of parts for displaying the train operation status are integrally defined as a scroll-like single-piece picture using a virtual coordinate system called a grid coordinate system. The data created by this definition is, for example, a plurality (M pieces) of display data 3-1 to 3-M created for each train route, and a plurality created for each route of a different system. (N pieces) of display data 4-N.

  Each of these display data is created so that a specific display component, for example, a station name display component is not used redundantly on one route, and an IC memory or a hard disk of a train operation status display device Stored in the data recording means.

Taking the display data 3-1 as an example, the entire display is shown as a wrapping paper display 5 and covers all the stations from the first station to the last station on one route. The display screen 6 is extracted and displayed in a state where, for example, three stations of X station, Y station, and Z station are connected.

  As a specific example, as shown in FIG. 2, the X station display part a, the Y station display part b, and the Z station display part c are displayed in a connected state, and the details of the Y station display part b therein are as follows. As shown in FIG. 3, at the center in the horizontal direction, a track display indicating a train track, a first home display continuous thereto, a home number display represented by a numeral 1 associated therewith, The 2 home display and the home number display represented by the numeral 2 associated therewith are represented by a picture, and in addition, it is composed of an arrow display and a traffic signal display in the train traveling direction.

  In the display area at the top of the display screen, a station name display and a station status display subordinate thereto, for example, character display such as manual, closed, station open, etc. are formed. There are a corresponding train number display, a set of train number windows subordinate thereto, and a set of train number displays corresponding to other trains and a subordinate train number window.

  The X station display part a and the Z station display part c are configured in the same manner as the Y station display part b that performs such detailed display.

  Each of these parts is stored in memory in a state that includes its own coordinate data along with its contents, and all display parts of the train operation status are horizontally long using a virtual coordinate system called a grid coordinate system. 4 is defined as a single picture, and is represented as a wrapping-like display data like symbol 5a in FIG. 4, and an area to be arbitrarily displayed is cut out from the single picture of the grid coordinate system. The display screen 6 is assumed.

  Here, the display area on the display screen 6 is referred to as a viewport (Viewport). When the size of the display screen 6 is equal to the size of the viewport (see reference numeral 5a), the display area 6 has the same size. Is larger than the viewport size (see reference numeral 5b), the viewport is reduced so that the viewport fits within the display screen 6, and conversely, when the display screen 6 size is smaller than the viewport size (see reference numeral 5c). ) Displays an enlarged viewport in the display screen 6.

  The coordinate transformation performed between the wrapping paper display 5 and the display screen 6 is performed using affine transformation. Affine transformation is a transformation method that moves figures and shapes by a combination of Euclidean linear transformation and parallel movement. Shear coordinates that can be expressed by 4x4 matrix operations for movement, rotation, left-right reversal, enlargement, and reduction. This is a conversion method in which geometrical properties are maintained such that points arranged on a straight line in the original figure are arranged on the straight line after conversion, and the original parallel line is a parallel line after conversion.

  As shown by reference numerals 5d and 5e in FIG. 5, the train operation status display system systematically has a rear viewport on the memory having the same display area size as the front viewport, and performs display. In some cases, the data of each part for forming the display screen is drawn on the back viewport.

  Since the back viewport is generally an IC memory, drawing can be performed at a high speed. On the other hand, the front viewport is a graphic display device, and therefore, data transfer is slow. It takes more time than drawing, and for this reason, a screen flicker phenomenon occurs in principle when the screen is switched.

  However, this flicker phenomenon does not substantially occur in the present invention. That is, when the drawing to the back viewport is completed, the content is copied to the front viewport which is the actual screen display, and the new display content is set to the actual display screen. Since a series of processing for display is completed instantaneously because it is performed by a graphic command, the flicker phenomenon does not substantially occur.

  In the above-mentioned [Embodiment 1], there are a plurality of display data 3 and display data 4 stored so as to cover the operation range from the start point to the end point of the train route. However, it is a matter of course that the data for displaying the wrapping paper may be the data for displaying one wrapping paper as long as the limit condition of the data storage capacity of one unit is satisfied.

  In addition, the data of one wrapping paper display is stored in units of train operating routes, but in the range of other formats, for example, when a plurality of railroad companies are interoperating with each other, the wrapping paper is displayed for each railroad company. Display data may be stored.

  In addition, the display by the component data that forms the data of the wrapping paper display is represented by a display area of a pattern or a predetermined shape. In addition to this display, if the attribute information, for example, the display is a train number, If you add train delay information, number of passengers on the train, limited express / normal, or if the part is a traffic light, type, number, installation station name, direction, starting point, landing window, control status, display Information indicating a storage area for information indicating a state can be additionally set.

It is a principle figure for demonstrating notionally the operation | movement of the screen display by [Example 1] of the train operation condition display apparatus by one embodiment of this invention. It is a top view of the station components which shows an example of the components used for the display screen shown in FIG. It is a top view which shows notionally the display mode of the component information of one station unit shown in FIG. It is a principle figure which shows notionally the operation | movement of the display conversion used for [Example 1] of this invention. It is a principle figure which shows notionally the operation | movement of the display switching used for [Example 1] of this invention.
