Description

  The present invention relates to an apparatus and a method for supporting creation of a station system.

  For example, train operation is managed using a station system that displays a control screen. The control screen of the station system is a screen that simply expresses the equipment of the station, and the state of the traveling train and equipment is displayed on the screen. Techniques for creating screen data to be displayed on such a station system are disclosed in Patent Documents 1 to 3.

  Patent Document 1 states that “a distinction between linked stations and non-linked stations is made, and a schematic diagram of each station is created as a separate schematic file, and after the creation, the order of the stations is input according to the route map on the display device. Then, the information processing apparatus creates a route map file by concatenating the schematic file in that order. "

  Further, Patent Document 2 describes that “providing a control screen creation support apparatus that can omit a check process when creating a control screen”.

  In patent document 1, since most of the creation of the station route map is performed by human labor, there is a problem that the number of creation man-hours is large. On the other hand, a method for reducing the total cost required to create a station route map by creating a station schematic map in advance and connecting the station schematic maps has been proposed. However, since most of the single station schematics created in advance are created by human labor, there is still a problem that the number of creation steps is large.

  In Patent Document 2, when creating a control screen, there is a problem that it takes a lot of time to create and check a screen specification when the number of facilities is enormous. On the other hand, a method has been proposed in which a check process at the time of creating a control screen is omitted by supporting creation of a screen specification that stores symbol information to be displayed on the control screen. However, Patent Document 2 does not disclose support for layout creation of the control screen, and there still exists a problem that the layout creation of the control screen has many manual input portions and the creation man-hour is large.

  In Patent Document 3, there is a problem that, when creating a database from a specification, an input error may occur in manual input. On the other hand, a method for automatically generating a database based on information extracted from design books has been proposed. However, there is no disclosure related to assisting the production of a control screen from a design book that extracts position information of the controller from the design book and has no position information. For this reason, the creation of the control screen layout for determining the position information of the controller still has many manual input parts, and there still remains a problem that the creation man-hour is large.

  An object of the present invention is to provide a technique that makes it possible to reduce the man-hours required for creating a screen of a station system.

  A station system creation support apparatus according to an aspect of the present invention includes an inter-part relation database that stores information indicating a relation between part types, a screen drawing database that stores images and display position rules for each part type, and a screen display. The design data including the parts list of the parts to be used is converted so that the relation between the parts is represented in a tree structure based on the inter-part relation database, and the part group data in which the relation between the parts is represented in the tree structure is generated. A screen by connecting the images of the components included in the component group data according to the tree structure and arranging them at a position according to the display position rule, based on the component list data conversion means that performs the screen drawing database Screen drawing means for creating

  Embodiments will be described with reference to the drawings. In this embodiment, a railway train operation management system will be described as an example.

  FIG. 1 is a diagram illustrating a configuration example of a station system creation support apparatus according to the present embodiment.

  The station system creation support apparatus 100 includes a calculation unit 110, a memory 120, an input unit 130, and an output unit 140.

  The calculation unit 110 includes a parts list data conversion unit 111, a station screen drawing unit 112, and a station screen data conversion unit 113. The memory 120 includes a parts list database (DB) 121, an inter-part relation DB 122, a station screen drawing DB 124, a station screen data conversion DB 125, and a part group parameter storage unit 123.

  First, the general operation of each part will be described.

  The inter-component relationship DB 112 stores information indicating the relationship between component types. The station screen drawing DB 124 stores images and display position rules for each component type. The parts list data converter 111 converts the screen display design data including the input parts list data 131 which is a list of parts used for the screen so that the relation between the parts is represented in a tree structure based on the inter-part relation DB 122. The parts group parameters (parts group data) represented by the tree structure are generated. Based on the station screen drawing DB 124, the station screen drawing unit 112 creates a station screen by connecting the parts images included in the part group parameters according to the tree structure and arranging them at positions according to the display position rules. As described above, since the station system creation support apparatus 100 supports the connection and arrangement positions of the components, it is possible to reduce the man-hours required for creating the screen of the station system.

  In the station screen drawing DB 124, the position where the component is arranged is defined as the display position rule of the specific component type, and the station screen drawing unit 112 selects the component type component where the position where the component is arranged is defined. Arrange at this position. As a result, a component that is determined to be arranged at a predetermined position on the screen is automatically arranged at that position, so that the component can be easily arranged at an appropriate position. For example, in the station screen drawing DB 124, the part type of the station name display defines the position where the part is arranged. Thereby, the station name display can be automatically arranged at an appropriate position, and the station name display positions of all the stations can be aligned.

  Further, in the station screen drawing DB 124, the relative position with respect to a component of another component type is specified as the display position specification of a specific component type, and the station screen drawing unit 112 has a relative position with respect to another component. Are arranged so that the relative positions of the parts of the part type defined for the part with the other parts related in the tree structure of the part group parameter comply with the provisions of the station screen drawing DB 124. As a result, a part whose relative position is fixed, such as one part being placed near another part, is automatically placed so that it is in that relative position. Can be arranged. For example, the station screen drawing DB 124 stipulates that the component type of the traffic light is arranged near the position where the track circuit is connected to the track circuit. Thereby, a traffic light can be automatically arrange | positioned in an inappropriate position. Further, the station screen drawing DB 124 stipulates that the component type of the switch is arranged near the position where the track circuit is connected to the track circuit. As a result, the tipping device can be automatically placed at an inappropriate position.

  Further, the station screen drawing unit 112 connects a plurality of components associated with each other in a tree structure in the component group parameter so as to be able to be changed afterwards. As a result, a plurality of parts associated in a tree structure are automatically temporarily connected, so that the user can easily know the relation between the parts by looking at the connection.

  Further, as an example, the station screen drawing unit 112 records information indicating the arrangement of the components after connecting the images of the components included in the component group parameters according to the tree structure and arranging the images in the positions according to the display position rule.

  As an example, the station screen data conversion DB 125 stores conversion rules (part structure rule information) between a data format of a station screen generated by the screen drawing unit 112 and a predetermined output data format. The station screen data conversion unit 113 converts the station image data created by the station screen drawing unit 112 into an output data format based on the station screen data conversion DB 125.

  As an example, the component list DB 121 stores parameter items and parameter value range specifications for each component type. The parts list data conversion unit 111 represents the design data based on the inter-part relation DB 122 and represents the relation between the parts in a tree structure, and based on the part list DB 121, the parameter items of the respective parts in the design data and the parameter items. The parameter information including the parameter value according to the parameter value range specification is set, and component group data including the parameter information represented by the tree structure is generated.

  Hereinafter, the present embodiment will be described in more detail.

  The component list data conversion unit 111 generates component group parameter data by converting the input component list 131, which is the design data input from the input unit 130, based on the component list DB 121 and the inter-component relation DB 122, Store in the component group parameter storage unit 123. The station screen drawing unit 112 draws a station screen based on the component group parameters stored in the component group parameter storage unit 123 and the data stored in the station screen drawing DB 124. The station screen data conversion unit 113 converts the station screen into output station screen data 141 based on the station screen data generated based on the part group parameters and the data stored in the station screen data conversion DB 125, and outputs the station screen data 141. Output from the unit 140.

  The component list DB 121 stores component type information and parameter item information of parameters that the target component can have. The inter-component relation DB 122 stores information indicating the correspondence between the component types. The parts group parameter storage unit 123 stores parts group parameters, which are work data generated by work. The station screen drawing DB 124 stores image information of each component used in the station screen drawing unit 114. The station screen data conversion DB 125 stores a conversion rule (part structure rule information) for converting drawn station screen data into an output data format.

  The input unit 130 receives input part list data 131 as design data and information on mouse operation and keyboard operation by a person from the terminal 132 or the like, and delivers the received information to the calculation unit 110.

  The output unit 140 receives the information of the output station screen data 141 in the output data format created by the station screen data conversion unit 113 from the calculation unit 110 and outputs it. Output here refers to displaying a screen or storing data in a memory.

  The component data of the input component list data 131 is a file having a structure similar to a list such as a csv file, a file having a list structure created by another application, for example, a table format file such as an XML file.

  FIG. 2 is a flowchart showing an outline of processing executed by the station system creation support apparatus 100.

  The station system creation support apparatus 100 first converts the input parts list data 131 into parts group parameters using the parts list DB 121 and the parts relation DB 122 in the parts list data conversion process (S100), and converts them to the parts group parameters. Store in the storage unit 123.

  Next, the station system creation support apparatus 100 draws a station screen using the information of the part group parameter storage unit 123 and the station screen drawing DB 124 as a station screen drawing process (S200).

  Finally, the station system creation support apparatus 100 converts the station screen data created by drawing into an arbitrary output file format such as XML or jpg and outputs it as the station screen data output process (S300).

  Hereinafter, the process flow of the station system creation support apparatus 100 will be described in more detail.

  In this case, a tabular data file (input parts list data 131) of a parts list created by another user for one station (station A) by another user using the station system creation support apparatus 100 is used. Therefore, a case where a station screen is created using the station system creation support apparatus 100 and station screen data in the XML file format is output will be described.

  FIG. 3 is a diagram illustrating an example of a screen initially displayed on the terminal 132.

  In the initial input screen (M100), in addition to the title name, the created station name input field (M101), the version number input field (M102), the input source path name input field (M103), and the output destination path name input field (M104) ), A screen data output format name selection column (M105), a parts list output format name selection column (M106), and a work start button (M107).

  In this embodiment, “A” is entered in the created station name input field (M101), “XML” is entered in the screen data output format name selection field (M105), and “csv” is entered in the parts list output format name selection field (M106). Is selected. The input source path name input field (M103) and the output destination path name input field (M104) are appropriately input or selected.

  FIG. 4 is a diagram illustrating an example of the input component list data 131 input to the station system creation support apparatus 100.

  The input part list data 131 includes a number (C101), a part name (C102), a part type (C103), a relation type (C104), and a related part name (C105). The number (C101) is a serial number assigned to each part. The part name (C102) is the name of the part. The component type (C103) is the component type of the component. The relationship type (C104) is a component type of a component (related component) related to the component. The related part name (C105) is the name of the related part.

  The actual data format of the input parts list data 131 is a text in which data is arranged in a comma-separated format or a table format file format (.CSV) created by another application. It is assumed that the input part list data 131 covers all parts necessary for creating the station screen of the station A.

  First, the parts list data conversion process (S100) will be described. As described above, the parts list data conversion process (S100) uses the parts list DB 121 and the inter-part relation DB 122 to convert the input parts list data 131 into parts group parameters in a tree format, and the parts group parameter storage unit 123. It is a process to store.

  FIG. 5 is a diagram illustrating an example of data relating to the track circuit stored in the component list DB 121.

  The data of the parts list DB 121 has a tree structure, and three types of parameters, a drawing parameter, a related parameter, and a control parameter, are described as child elements for the part type of the root element. The root element indicates the target component type. The drawing parameter is a parameter used for drawing a component of the component type of the root element. The related parameter is a parameter for the component type of the component associated with the component of the component type of the root element. The control parameter is a parameter for controlling the component of the component type of the root element. Each parameter item defines a value that can be set as the parameter.

  Referring to FIG. 5, the root element is a track circuit, and the above-described three types of parameters are defined for the track circuit. For example, the drawing parameters include reference coordinates for drawing the trajectory circuit and the coordinates of the start point of the branch, both of which can be set ((0 or more integer), (0 or more integer)).

  Further, the track circuit can be adjacent to the track circuit. Those parts become related parts. In the example of FIG. 5, the component type “track circuit” (C201) is associated with the related type “adjacent track circuit” (C202), and the specified type “track circuit” (C202) C203). This regulation “track circuit” (C203) indicates that the related component of the related type “adjacent track circuit” (C202) is the component type “track circuit”, and “2RAT” in FIG. 4 is the track circuit. Means.

  It should be noted that, in addition, rules and constraint parameters may be described as child elements in each parameter.

  FIG. 6 is a diagram showing a table of relationships between component types stored in the inter-component relationship DB 122. The inter-component relation DB 122 describes the relationships that can be made between the component types.

  In this embodiment, when the component type “track circuit” (C302) is related to the component type “track circuit” (C301), it indicates that the related name is “adjacent track circuit” (C303). In that case, the “owner end” (C304) is auxiliary information of the related name. The possessing end is an end point connected when the track circuit is adjacent to another track circuit.

  FIG. 7 is a diagram illustrating an example of data stored in the component group parameter storage unit 123.

  The component group parameter data stored in the component group parameter storage unit 123 is created from the information in the inter-component relation DB 122 in FIG. 6 and the input component list data 131 in FIG.

  In the component group parameters of FIG. 7, “1” (C601), “track circuit” (C602), “11T” (C603), “adjacent track circuit” (C606), and “2RAT” (C607) are inputs of FIG. This is information described in the parts list data 131. Further, “carrying end” (C604) is information added by referring to the inter-component relation DB 122 of FIG. “3” (C 605) is information calculated from the input component list data 131 of FIG. 4 and added. From FIG. 4, the track circuit “11T” has three “adjacent track circuits”. For this reason, information “held end” (C304) and information “3” are added to the component group parameters. As described above, in this embodiment, information for determining the shape of a component is incorporated as a parameter, and the input component list data 131 is converted into a component group parameter suitable for screen drawing.

  Next, a station screen drawing process (S200) for drawing a station screen using information of the component group parameter storage unit 123 and the station screen drawing DB 124 will be described.

  FIG. 8 is a flowchart showing an overview of the station screen drawing process (S200).

  First, a component installation process (S201) is performed in which the station screen drawing unit 112 installs components included in the component list stored in the component group parameter storage unit 123 based on the station screen drawing DB 124. The installation here is, for example, drag and drop.

  Next, the component automatic placement process S202 is performed in which the components are placed on the screen by connecting the components according to the station screen drawing DB 124 and determining the position of the component.

  Finally, an arrangement information management process (S203) for generating drawing parameters (see FIG. 5), which is information indicating the arrangement of the parts, is performed based on the installation positions of the parts on the screen.

  An example of the component installation process (S201) illustrated in FIG. 8 will be described.

  FIG. 9 is a diagram illustrating an example of data stored in the station screen drawing DB 124.

  In this embodiment, the data of the station screen drawing DB 124 is composed of “number (No)” (C401), “part type” (C402), “image” (C403), and “position definition” (C404). . When a component in the component list of the component group parameter storage unit 123 is installed on the screen of the station screen drawing unit 112, an image indicated by an “image” (C403) corresponding to the component type of the installed component is displayed on the station screen drawing unit 112. Displayed on the screen.

  FIG. 10 is a diagram showing an example of the entire screen displayed on the terminal 132 in the station screen drawing process (S200).

  The screen of the station screen drawing unit 112 includes a parts list display unit (M201), a station screen display unit (M202), and a menu display unit (M203). In the parts list display section (M201), a table describing information on each part is displayed. A station screen to be created is displayed in the station screen display section (M202). The menu display unit (M203) displays buttons for adding, switching, reflecting, and outputting data.

  The parts in the parts group parameter storage unit 123 are displayed in the parts list display unit (M201). When a part in the parts list display unit (M201) is dragged and dropped to the station screen display unit (M202), the station screen drawing DB 124 is displayed. Is reflected in the image of the station screen display section.

  An example of the component automatic placement process (S202) shown in FIG. 8 will be described.

  This process is performed based on the related parameters stored in the parts group parameter storage unit 123 and the position definition of the station screen drawing DB 124.

  The component automatic placement processing (S202) is classified into three patterns.

  The first is automatic adjustment of the part position when the reference position of the part is fixed, and the second is automatic adjustment of the part position when the reference position is determined according to the position of the related part. There is a third case where the position of the part is not automatically corrected. In the third case, the arrangement of the components is not automatically corrected, but the connection between the components is determined by the relationship between the arranged components, and the shape of the connection line may change.

  FIG. 11 is a diagram for explaining a process for automatically arranging station boxes indicating station names.

  In this embodiment, the station box corresponds to the first pattern of automatic component placement. When “A station”, which is a part type “station name box”, is installed at an arbitrary position in the station screen display section (M202) (M301), the position specified by the position definition “C404” of the station screen drawing DB 124 is set to “ An image of “A station” is automatically arranged (M302). Note that after this automatic placement is performed, it is possible to manually move the image of “Station A” within a specified range.

  FIG. 12 is a diagram for explaining automatic signal placement processing.

  In this embodiment, the traffic light corresponds to the second pattern of automatic component placement. With the component type “track circuit” “2RAT” and “21T” installed, the component type “signal” “4R” is installed at an arbitrary position on the screen of the station screen display unit (M202). And (M401), the related parameter for the track circuit related to “4R” in the component group parameter of the component group parameter storage unit 123 is confirmed based on the position definition “C404” of the station screen drawing DB. Based on the positions of “2RAT” and “21T” described in the related parameters of “4R”, the reference position of “4R” is calculated, and “4R” is automatically arranged at the reference position (M402). For example, the calculation formula for the reference position (x, y) of the component type “signal” is as follows.

  x = (same X coordinate as the boundary point of two related track circuits a and b)

  y = (Y coordinate of the boundary point between two related track circuits a and b) ± {(length of boundary line) × 0.5 + (margin)}

  The boundary line is a line indicating a boundary between two track circuits, and is a line that intersects a line connecting the two track circuits. The margin is an appropriate distance separating the boundary line from the traffic light. Note that after this automatic placement is performed, it is possible to manually move the “4R” image within the specified range.

  FIG. 13 is a diagram for explaining a process of automatically connecting track circuits.

  In this embodiment, the track circuit corresponds to a third pattern of automatic component placement, and the connection between components is determined by the relationship between the components.

  First, the track circuit “11T” is installed at an arbitrary position on the screen by the station screen display unit (M202) (M501). Next, the track circuit “2RAT” is installed at an arbitrary position on the same screen by the station screen display unit (M202). Then, it is confirmed by the parts list display unit (M201) whether or not “11T” which is the adjacent track circuit of “2RAT” has been drawn. Since “11T” has already been drawn here, “2RAT” and “11T” are connected by a line on the screen. At this time, if both of “2RAT” and “11T” have one vacant end (C604), the vacant possessing ends are immediately connected. On the other hand, if one of “2RAT” and “11T” has two or more free possessing ends, it is temporarily connected to either one (M502).

  When the temporary connection is made, finally, an appropriate connection is selected by the user's operation, and the connection is determined by that (M503). After this automatic connection is performed, the line connection position and the line break position may be changed within a specified range.

  An example of the arrangement information management process (S203) shown in FIG. 8 will be described.

  In the arrangement information management process (S203), the correction is reflected in the drawing parameters of the component whose position has been changed based on the arrangement information of the screen by the station screen display unit (M202).

  Here, as shown in FIG. 10, it is assumed that “1L” in the parts list display section (M201) is not yet drawn on the station screen display section (M202) (M204). In the drawing flag (M205) of the parts list display unit (M201), “x” indicating that the drawing is not performed is indicated. Thereby, it is possible to prevent drawing leakage of components.

  Finally, the station screen data output process (S300) shown in FIG. 2 will be described. In the station screen data output process (S300), the station screen data created in the station screen drawing process (S200) is output in an arbitrary output file format such as XML or jpg. The data stored in the station screen data conversion DB 125 is changed according to the drawing parameters for each component included therein, and a file in the output file format is created and output by combining them.

  FIG. 14 is a diagram illustrating an example of data stored in the station screen data conversion DB 125.

  The data stored in the station screen data conversion DB 125 is composed of “format” (C501), “part type” (C502), and “conversion structure” (C503). The data of the conversion structure is determined by the format and the component type, and the conversion structure data is created by applying the component name and drawing parameters.

  In this embodiment, the generated station screen data is output in the XML format.

  The content of the XML file has a hierarchical structure with a plurality of tabs. The station screen data conversion DB 125 stores XML configuration data that forms each part.

  In the station screen data output process (S300), the data stored in the station screen data conversion DB 125 is changed according to the drawing parameters of each component, and an XML file is created and output by combining them.

  For example, the output XML file is described as follows.
