  The present invention relates to a train information display device that graphically displays train information using a display device installed in a train vehicle.

  In recent years, a system for distributing and providing video information to passengers using a display device installed in a train vehicle has been proposed and put into practical use. In a conventional train information display device, contents constituting a guidance screen such as destination guidance and arrival guidance are stored in advance in the storage unit of the display device as one piece of content for each screen.

  In this way, in the train information display device, since one piece of content is displayed on each screen stored in the storage unit, only part of the train information such as the train type, destination, or car number is different, and the other information is the same. Even so, it is necessary to create a new content and store it in the storage unit. Therefore, there is a problem that the data storage capacity increases according to the number of contents.

  For example, in the system described in Patent Document 1, a storage unit that stores component-level content (partial content) corresponding to train information configuring a guidance screen is provided, and necessary partial content is stored in accordance with train information. Selected from the department. The selected partial content is arranged at a predetermined position on the guide screen to constitute the guide screen. Thereby, the data storage capacity can be reduced, and the addition and correction of the guidance screen can be easily handled.

Japanese Patent No. 3875950

  However, in the system described in Patent Document 1, since the partial content is an image, display languages and fonts (type, size, etc.) such as Japanese, Hiragana, and English differ even if the partial content indicates the same station name. In such a case, the contents must be managed as different contents, and there is a problem that the data storage capacity increases.

  Then, an object of this invention is to provide the train information display apparatus which can reduce the data storage capacity required for a display.

  The train information display device according to the present invention is a train information display device that is mounted on each vehicle constituting a train and receives train information and displays a guidance screen, and the content that constitutes the guidance screen In accordance with the management means for collectively managing the same type at the same station, and the order of the display language of the guidance screen stored in advance, the guide screen from the station information, the running state and the train type included in the train information. A configuration for configuring the guide screen by arranging the selected content in accordance with selection means for selecting content necessary for configuration and screen layout information indicating the layout of the content on the guide screen stored in advance. And means for expanding the guide screen in accordance with a screen expansion schedule stored in advance.

  According to the present invention, the station information included in the train information in accordance with the order of the management language that collectively manages the contents of the guidance screen that are related to the same type at the same station and the display language of the guidance screen stored in advance. By selecting the content according to the selection means for selecting the content necessary for configuring the guidance screen from the traveling state and the train type, and the screen layout information indicating the content layout on the guidance screen stored in advance Configuration means for configuring the guide screen, and expansion means for expanding the guide screen in accordance with a screen expansion schedule stored in advance.

  Therefore, as described above, contents related to the same type are managed together at the same station, so even if the display language and font (type, size, etc.) are different, they can be managed as one content. Thereby, the data storage capacity required for display can be significantly reduced.

<Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a train information display device according to an embodiment of the present invention. The train information display device is a device that is mounted on each vehicle constituting the train, and that receives the train information and displays a guidance screen. The train information display device includes a train information providing device 10 that calculates and provides train information based on information sent from an external ground system (not shown), and a display device 20 that displays a guidance screen. Yes. One train information providing apparatus 10 is mounted on a train, for example. Moreover, the display apparatus 20 is mounted in multiple units (for example, 3 units) for every train vehicle, for example. Here, the train information is information including station information (for example, information on a current station where the train is present), a running state of the train (for example, up / down, display pattern), and a train type.

  Next, the display device 20 will be described with reference to FIG. FIG. 2 is a block diagram of the display device 20. The display device 20 includes a storage unit 21, a display unit 32, a communication unit 30, and a display parameter generation unit 31. The storage unit 21 is a memory or the like that stores various definition files and contents described later, and includes a content storage unit 22 and a definition file storage unit 25. The content storage unit 22 functions as a management unit that collectively manages content related to the same type at the same station with respect to the content constituting the guidance screen. Details of the content storage unit 22 and the definition file storage unit 25 will be described later.

  The display unit 32 includes a screen generation unit 33 and a screen switching unit 34 and is connected to the storage unit 21. The screen generation unit 33 functions as a selection unit that selects, from the content stored in the storage unit 21, content necessary for configuring the guidance screen from train information in accordance with the order of the display language of the guidance screen stored in advance. . The screen generation unit 33 also functions as a configuration unit that configures the guidance screen by arranging the selected content according to the screen arrangement information indicating the arrangement of the content on the guidance screen stored in advance.

  The screen switching unit 34 functions as an expansion unit that expands the guide screen in accordance with a screen expansion schedule stored in advance. The expanded guidance screen is displayed on a screen 35 connected to the screen switching unit 34.

  The communication unit 30 receives train information from the train information providing apparatus 10 in a command format. The display parameter generation unit 31 refers to the definition file stored in the definition file storage unit 25 of the storage unit 21 and generates display parameters for configuring the guidance screen from the command received by the communication unit 30. Here, the memory | storage part 21, the display part 32, the communication part 30, and the display parameter production | generation part 31 are implement | achieved by the predetermined software which operate | moves in cooperation with hardware, such as CPU, for example, for example.

  Next, definition files and contents stored in the storage unit 21 will be described. FIG. 3 is a diagram illustrating an example of the storage content of the content storage unit 22, and FIG. 4 is a diagram illustrating an example of the storage content of the definition file storage unit 25.

  As shown in FIG. 3, the content storage unit 22 includes a guide content storage unit 23 that stores guide content indicating a guide screen, and a partial content storage unit 24 that stores component-level partial content arranged on the guide screen. Have Here, in FIG. 3, a guidance content 40 named “arrivingGuidance” and a guidance content 50 named “boundforGuidance” are stored as an example of guidance content. As an example of partial content, a partial content 42a named “shubetu”, a partial content 44a named “Text”, a partial content 45a named “Car”, and a partial content 52a named “lineName” Is remembered.

  The guidance content storage unit 23 stores arrangement positions 41 to 46 and 50 to 52 of the partial contents 42a, 44a, 45a, and 52a on the guidance screen. Note that the content is a generic name including guidance content and partial content.

  Although partial content is managed centrally by name, another image can be set for guidance content with the same name using attributes such as display language, train type, and station ID. For example, a character string indicating a normal train and a character string indicating a rapid train are defined in the partial content 42 a called “shubetu”. If the value of the train type in the train information given from the outside is “1”, it is normal, and if it is “2”, rapid is selected.

  The guidance content defines where the partial content is displayed (arranged) on the guidance screen. The guidance content is managed by name in the same way as the partial content. For example, as shown in FIG. 3, there is guidance content 40 named “arrivingGuidance” for arrival guidance, and guidance content 50 named “boundforGuidance” for destination guidance. In each of the guide contents 40 and 50, layout positions of the partial contents 42a, 44a, 45a, and 52a stored in the partial content storage unit 24 are laid out.

  For example, in the case of the guidance content 40, the arrangement position 42 of “shubetu” indicating the train type, the arrangement position 43 of “ikisaki” indicating the destination / direction, the arrangement position 44 of “Text” indicating the guidance, and the “StationName” indicating the arrival station An arrangement position 41 of “Car”, an arrangement position 45 of “Car” which is a prefix indicating the car number, and an arrangement position 46 of “No” indicating the car number are defined.

  In the case of the guidance content 50, an arrangement position 52 of “lineName” and an arrangement position 51 of “ikisaki” are defined. In this way, it is defined at which position and in what size the partial content is displayed in the guidance content.

  In addition, although the content of guidance content can also be described in a text format, such content can also be produced | generated with a commercially available tool. For example, Adobe Flash Professional (registered trademark) can create and store content graphically.

  As shown in FIG. 4, the definition file storage unit 25 stores definition files such as station definition information, required time information, stop station information, screen development definition information, and screen layout information. The station definition information defines station attributes (specifically, a station ID for identifying a station and a character string in a language). The required time information is defined by dividing the required time between stations into uplink and downlink. Stop station information defines the stop station for every train classification.

  The screen development definition information is the guidance screen development order and schedule (more specifically, guidance content, display language, and display time used for each display pattern included in the command transmitted from the train information providing apparatus 10). Define The screen arrangement information defines selection, arrangement, and size of partial contents arranged in the guidance content.

  FIG. 5 is a diagram illustrating an example of station definition information. In the station definition information, station names displayed in a plurality of types of languages are collectively defined for each station. Specifically, a character string indicating a station name in each language of Japanese (Kanji), Hiragana, English, Korean, and Chinese is defined for the station ID. For example, when the station ID is M09, “Momoyamadai” is selected if the attribute is Japanese, and “Momoyamadai” is selected if the attribute is English.

  FIG. 6 is a diagram illustrating an example of stop station information. In FIG. 6, the station IDs are arranged with the lower side as the upward direction and the upper side as the downward direction. When stopping at the station indicated by the station ID for each type of train, ○ is input, and when not stopping, a blank is input. For example, if the current station is an M10 fast train, the next station to stop is M13. On the other hand, if the current station is an M10 up-bound ordinary train, it indicates that the next station to stop is M11.

  FIG. 7 is a diagram illustrating an example of the required time information. In FIG. 7, M08 to M16 are assigned as the departure station in the row direction and the arrival station in the column direction, respectively, and the required time between the stations is input. For example, if the current station (departure station) is an up-bound ordinary train with M11, when calculating the required time to M12, which is the next station (end station), the numerical value of the overlapping location where the departure station is M11 and the destination station is M12 Is the required time. This indicates that the required time is 2 minutes. Similarly, the time required from M12 (departure station) to M13 (arrival station) is also 2 minutes.

  FIG. 8 is a diagram illustrating an example of the screen development definition information. The screen development definition information is classified for each display pattern included in the command transmitted from the train information providing apparatus 10, and which guidance content is used in each display pattern and in which language the guidance content is displayed. Define. For example, in the case of the display pattern 3 indicating that the vehicle is stopped, the guidance content to be used is guidance content named “Stopping”, and the display language is switched in the order of Japanese, Hiragana, and English every 3 seconds. .

  In this case, among the partial contents included in the guidance content named “Stopping”, the partial contents having the language attribute are switched to the designated language. For example, in FIG. 3, the text “Text” uses “Soon” for Japanese or Hiragana, and “Arriving” for English.

  FIG. 9 is a diagram showing a guidance screen displayed as an arrival guidance as an example of the guidance screen, and FIG. 10 is a diagram showing screen layout information in the case of the guidance screen shown in FIG. As shown in FIG. 9, partial contents 60 to 73 are arranged on the guidance screen. As shown in FIG. 10, the screen layout information defines information to be displayed (arranged) on the guidance screen using the identifier (character string) of the partial content included in the guidance screen as a key.

  When the guidance content on the guidance screen is “arrivingGuidance”, it indicates that the arrangement information is (200, 250), the size is 70, and the station ID is 0 for “current” whose part name indicates the current station. A station ID value of 0 indicates an offset for the current station. If the station ID is +1, the next station is indicated, and if the station ID is +2, the station is indicated successively. For example, if the part name is next [1], the station ID is +2, so that the displayed station name corresponds to the station name specified by the station ID of the station after the current station.

  Next, the overall operation of the train information display apparatus will be described with reference to FIG. FIG. 11 is a flowchart showing the operation of the train information display device. The CPU reads the definition file from the definition file storage unit 25 (step S1). The CPU receives a command transmitted from the train information providing apparatus 10 (step S2). If the reception of train information has been completed (Yes in step S3), this operation is terminated. If not (No in step S3), train information (more specifically, display pattern, up / down, train type, current station data) is acquired from the received command (step S4).

  Next, the CPU determines whether or not the expansion is completed if the screen is being expanded (step S5). If the expansion is completed (Yes in step S5), the CPU proceeds to step S2 and receives the command again. Otherwise (No in step S5), the CPU generates a display parameter from the acquired command (step S6).

  FIG. 12 is a diagram illustrating an example of display parameters. The display parameters shown in FIG. 12 are parameters for generating the guidance screen (guidance content name arrivingGuidance) of FIG. With the current station current as M13, pass [0] to pass [2] which are partial contents indicating the passing station, next [0] to next [2] which are partial contents indicating the stop station, and partial contents indicating the required time Values of certain time [0] to time [2] are calculated from the screen layout information. And CPU produces | generates a guidance screen using a display parameter and screen arrangement | positioning information (step S7).

  Next, display parameter generation processing will be described using the flowchart of FIG. FIG. 13 is a flowchart showing display parameter generation processing. The CPU acquires a display pattern from the command (step S11). Here, the acquired display pattern is 2. The CPU acquires guide content corresponding to the display pattern from the screen development definition information (step S12). Specifically, the CPU acquires ArrivigGuide corresponding to the display pattern 2 from the screen development definition information shown in FIG.

  The CPU acquires information on the up / down, current station, and train type from the command (step S13). Here, it is assumed that the CPU acquires that the current station M13 and the train type are normal, going down. The CPU refers to the station stop information, and calculates the stop station and the passing station from the information of the up / down, current station, and train type (step S14). Here, the stop stations related to the current station M13 are after M14, that is, M14, M15, and M16, and the passing stations are before M12, that is, M12, M11, and M10.

  The CPU refers to the required time information and calculates the required time from the current station to the stop station (step S15). From the required time information shown in FIG. 7, it can be seen that the required time from the current station M13 is 2 minutes to M14, 4 minutes to M15, and 6 minutes to M16. CPU acquires a car number from the command received from the train information provision apparatus 10 (step S16), and complete | finishes this process.

  Next, the guidance screen generation process will be described with reference to FIG. FIG. 14 is a flowchart showing the guidance screen generation process. The CPU acquires guide content to be displayed from the display pattern included in the received command (step S21). Here, assuming that the display pattern is 2, the guiding content is selected as the guidance content from the screen development definition information shown in FIG.

  The CPU acquires the first display language from the screen development definition information shown in FIG. 8 (step S22). Here, the first acquired language is JP: Japanese. The CPU acquires, from the partial content storage unit 24, the partial content related to the station name arranged at the partial content arrangement position in the guidance content from the station definition information and the display parameters (step S23).

  Here, assuming that current = M13, the station name is “Shin-Osaka” from the station definition information of FIG. Similarly, for the next station next [] from the display parameters, the next station is M14 “Nishinakajima Minamikata”, the next station is M15 “Nakatsu”, and the passing station pass [] is M12 “East Mikuni”, M11 “Esaka” or the like is selected from the partial contents. Similarly, because destination station ikisaki is M16, it becomes “Umeda”.

  The CPU selects partial content related to the required time from the station definition information, the stop station information, the required time information, and the display parameters stored in the definition file storage unit 25 (step S24). Here, since time [0] is 2 minutes, the partial content of 2 is acquired from the partial content storage unit 24.

  CPU acquires the partial content regarding a train classification and a car number from a display parameter (step S25). Here, assuming that the train type is “1”, the “normal” partial content is acquired from the partial content storage unit 24. Since the car number is “7”, the partial content “7” is acquired from the partial content storage unit 24 in the same manner. Based on the screen arrangement information, the CPU arranges the partial content at the designated position and displays it at the designated size (step S26). Note that the arrangement, enlargement / reduction of the acquired partial content may be performed using a general vector graphic engine.

  Next, the screen switching process will be described with reference to FIG. FIG. 15 is a flowchart showing the screen switching process. The screen switching process is executed during the guidance screen generation process (step S7) shown in FIG. Here, the guidance screen will be described as arriving Guidance, and the current station will be described as M13. The CPU acquires the timing for switching the guidance screen display from the screen development information stored in the definition file storage unit 25 (step S31). Here, since the display time of the first screen from the screen development information (display pattern = 2) shown in FIG. 8 is 3 seconds, the time point at which 3 seconds have elapsed is the next guide screen display timing.

  The CPU acquires the attribute of the next guidance screen from the screen development information, and changes the display of the partial content with reference to the station definition information stored in the definition file storage unit 25 (step S32). Here, the attribute of the next guidance screen is “KANA”, which indicates that the hiragana is displayed. Therefore, the CPU changes the attribute of the partial content on the guidance screen from “JP” to “KANA”. The display of the partial content “current” was “Shin-Osaka” in the attribute “JP”, but since the attribute is “KANA”, it is changed to “Shinosaka” in Hiragana based on the station definition information.

  In step S33, such attribute switching is repeated for all partial contents included in the guidance screen. If the CPU has switched the attributes for all the partial contents (Yes in step S33), the CPU waits until the next guide screen display switching timing according to the screen development information. When the next guidance screen display switching timing is reached, if the screen development is not completed (No in step S34), the CPU proceeds to step S31 and acquires the guidance screen display switching timing from the screen development information. On the other hand, when the screen development is completed (Yes in step S34), the CPU ends this process.

  As described above, in the train information display device according to the first embodiment, with respect to the contents constituting the guidance screen, the management means for collectively managing the same type at the same station, and the display language of the guidance screen stored in advance Selection means for selecting the content necessary for constructing the guidance screen from the station information, the running state, and the train type included in the train information, and screen arrangement information indicating the arrangement of the content on the guidance screen stored in advance And a configuration unit that configures the guidance screen by arranging the selected content, and an expansion unit that expands the guidance screen according to a screen expansion schedule stored in advance.

  Therefore, as described above, contents related to the same type are managed together at the same station, so even if the display language and font (type, size, etc.) are different, they can be managed as one content. Thereby, the data storage capacity required for display can be significantly reduced.

  More specifically, the above content is described. Screen layout information that defines the layout of part-level partial content that constitutes the guide screen on the guide screen, station definition information that defines station attributes, and the type of train Definition file storage for storing a definition file including stop station information for defining each stop station, required time information for defining the required time between stations, and screen expansion definition information for defining the expansion order and schedule of guide screens A unit 25 is further provided.

  In addition, the management means includes a content storage unit 22 having a guide content storage unit 23 that stores guide content indicating a guide screen, and a partial content storage unit 24 that stores partial content related to the same station together, and is selected. The means selects partial content based on the definition file defined in the definition file storage unit 25, and the configuration means generates a guidance screen by arranging the selected partial content according to the screen arrangement information. 33, the expansion means includes a screen switching unit 34 that expands the generated guide screen according to the screen expansion definition information and switches the guide screen.

  In this way, content related to the same type is managed together at the same station, so even if the display language and font (type, size, etc.) are different, it can be managed as one content. Thereby, the data storage capacity required for display can be significantly reduced.

  Conventionally, since the information of all partial contents constituting the guidance screen is described in the definition file, when the number of partial contents increases, an appropriate partial content is selected and described from many partial contents. It was difficult. For this reason, there is a problem that it takes time to create the definition file.

  On the other hand, in the train information display device according to the present embodiment, referring to the station definition information and the stop station information stored in the definition file storage unit 25, from the station information and the train type included in the train information, It further includes a display parameter generation unit 31 that calculates an ID indicating a stop station and a passing station and a required time to the stop station, and generates a display parameter. The screen generation unit 33 refers to the screen arrangement information, and displays the display parameter. A guide screen is generated from

  Therefore, it is possible to generate a display parameter that can specify which content is allocated to the partial content that constitutes the guidance screen. As a result, when displaying the guidance screen, it is only necessary to specify the type, arrangement coordinates, and size of the partial content, so it is not necessary to define information on all the partial contents constituting the guidance screen, and the definition file can be easily created. It becomes. For this reason, the design cost of a train information display apparatus can be reduced. In addition, since the definition file can be easily created, the production process time in the train information display device can be reduced.

  In the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.
