  The train operates according to the planned schedule 5 planned in advance. However, the actual operation (actual results) differs from the plan depending on the number of passengers and the weather. At this time, the commander who manages the train operation finds the train that is running later than planned from the train operation status obtained from the display 16, and considers the cause analysis and the operation status of the entire route to plan the operation (implementation) Diamond) must be changed. In the present invention, the display on the train operation display is as follows.

  FIG. 1 is an outline of an embodiment of the present invention, and shows an overall configuration of a train operation command device and an image displayed by the present invention. 2 and 3 show an example of a flowchart of the present invention.

  4 (a) and 4 (b) are examples of a common format of implementation diagram / result diagram data according to the present invention. The data includes “data No.” that is an ID unique to the data, “operation number” that is a train-specific number, “start station” and “destination station” of the train, arrival time and departure time of each station, “Y station arrival time” “Y station departure time” “Z station arrival time”, data No. “Previous stroke data No.”, data No. indicating the diamond after the return. “Post-stroke data No.” is stored.

  5 and 6 show examples of the data format of the route map format screen. FIG. 5 memorizes the state of falling and climbing on each track by the train operation number resulting from it. FIG. 6 stores the current display state for each traffic signal as a progress display / stop display.

  Hereinafter, the outline and basic flow of processing in the train operation command device to which the present invention is applied will be described with reference to FIGS. 1, 2, 3, 4, 5, and 6.

  The flowchart of FIG. 2 shows a process in which the signal equipment data 2, the train operation data 3, and the performance diagram 4 are updated so as to reflect the actual operation status (route control state, train traveling state). The operation status receiving unit 1 receives train operation information and signal facility information, stores them as signal facility data 2 and train operation data 3, and edits and stores the result data of each train station in the result diagram 4.

  The flowchart of FIG. 3 shows processing from when the display screen is designated by the position designation unit 19 to the WEB browser 17 in the client computer 24 until the screen is actually displayed on the WEB browser. The boxes 41 to 42 and 52 to 53 in the flowchart of FIG. 3 are processes on the client computer side, and the other boxes indicate processes on the server computer side.

  The commander who manages the train operation designates a screen display command displayed on the WEB browser 17 using the position designation unit 19.

  The WEB browser 17 transmits a screen display request to the server computer 23 via the request transmitting unit 20 based on the screen display command specified using the position specifying unit 19. However, when the screen is selected by the WEB browser, if the selection screen is a streak-type screen, it is checked whether the streak display unit is incorporated in the WEB browser. If not, the streak display unit stored in the server is checked. 25 is downloaded to the client and incorporated into the WEB browser.

  The request reception unit 10 transmits a data extraction query to the database via the data extraction unit 7 based on the type of the received screen display request. In the case of a route map format screen display request, signal facility data / train operation data / equipment condition extraction query is transmitted, and in the case of a streak format screen display request, an execution diagram / result diagram extraction query is transmitted.

  If the requested screen is a route map screen, the data organizing unit 9 uses the route map format screen from the signal equipment data 2, the train operation data 3, and the equipment condition 6 which is a constraint condition for the train to travel on the route. The data is arranged in a form used when creating the drawing data and is passed to the request receiving unit 10. In addition, when the requested screen is a route map screen, the data organizing unit 9 organizes the performance diagram 4 and the implementation diagram 5 and passes them to the request receiving unit 10.

  The request receiving unit 10 activates the data analysis unit 11, and the data analysis unit 11 draws the drawing conditions stored in the drawing condition file 13 (line type / line color / line width of streaks, time displayed on one screen on the streak screen) Width, etc.).

  The drawing data creating unit 12 creates screen drawing data from the analysis result of the drawing condition file 13 by the data analyzing unit 11 and the data extracted from the database and arranged by the data organizing unit.

  The drawing data transmitting unit 14 transmits the drawing data created by the drawing data creating unit 12 to the drawing data receiving unit 15 on the client computer side.

  The drawing data receiving unit 15 passes the drawing data received from the drawing data transmitting unit 14 to the WEB browser 17.

  When the drawing data passed to the WEB browser 17 is a route map format screen, the WEB browser displays data on the display 16 based on the drawing data created by the drawing data creation unit 12 only with its own function.

  On the other hand, when the drawing data passed to the WEB browser 17 is a streak format screen, the WEB browser uses the function of the streak display unit 18 to transfer the data to the display 16 based on the drawing data created by the drawing data creation unit 12. Display.

  The implementation schedule 5 has already stored a train operation plan diagram that takes into account equipment conditions and the like. The equipment condition 6 stores signal equipment conditions on the route. The actual record 5 stores actual data of arrival time and departure time up to the current time at each station of the train.

  The signal equipment data 2 stores the state of the signal equipment received by the operation status receiving unit 1. The train operation data 3 stores train operation data representing the current position of the train received by the operation status receiving unit 1.

  The diagram display 21 displays an implementation diagram (thin line) and a record diagram (thick line) that is a record of train operation. The horizontal axis shows the passage of time, and the vertical axis shows the train position. The route map display 22 displays the position of the train and the state of the traffic signal.

  The commander usually grasps the train position and the mutual positional relationship with other trains on the route map format screen, and judges the delay from the plan diagram on the streak format screen.

  Next, a method of performing a diamond time change operation by a streak operation using the web browser built-in streak display unit 18 will be described with reference to FIG.

  When the time change screen display command is specified from the WEB browser using the position specifying unit 19, the time change screen 64 is displayed on the right side of the streak format screen.

  When the train number of the diamond whose time is desired to be changed is entered in the train number input field in the time change screen 64, the editing stripe 61 is displayed on the corresponding stripe 60. At the same time, the arrival / departure time of the editing stripe is input to the arrival / departure time input field of the time change screen. Further, a symbol (drag handle 62) that can be dragged with the mouse is additionally displayed at the starting point of the editing stripe 61.

  The commander moves the mouse pointer 63 to the drag handle 62 displayed at the station where the time is to be changed, and drags it to the right to lower the time, and to the left to increase the time. Then, the shape of the editing stripe changes so that the time changes according to the drag operation of the mouse (in this example, all drag stripe vertices after the dragged drag handle are dragged with the mouse dragged) Move the same amount as). At the same time, the arrival time of the editing stripe whose time is changed by dragging the mouse is updated and input to the time change screen 64.

  The commander confirms whether the change result is correct by looking at the input contents of the arrival / departure time on the time change screen. If it is not correct, edit the arrival / departure time input field on the time change screen by directly entering a numerical value.

  Finally, after confirming that the input content on the time change screen is correct, the commander transmits the input content on the time change screen to the server by clicking the execution button 65 on the time change screen with the mouse. The contents transmitted to the server are checked for rationality. If they are correct, the server database is updated according to the contents of the transmitted time change, and the updated diagram is displayed on the WEB browser.

  FIG. 7 shows an example of a format of streak data to be input to a streak display unit incorporated in a WEB browser according to the present invention. This streak data is in a vector format, and processing such as streak enlargement display and streak operation can be performed only on the client computer side without performing communication with the server computer. The data includes “data No.” that is an ID unique to the data, “operation number” that is a train-specific number, “start station” and “destination station” of the train, and coordinates “vertex 1X coordinate” and “vertex 1X coordinates” of each streak. Vertex 1Y coordinate "" Vertex 2X coordinate "" Vertex 2Y coordinate "" Vertex 3X coordinate "" Vertex 3Y coordinate ", data No. “Previous stroke data No.”, data No. indicating the diamond after the return. “Post-stroke data No.” is stored.

  The streak display unit incorporated in the WEB browser holds the above-described vector format streak data. Therefore, when the streak screen is enlarged / reduced, the streak screen enlarged / reduced based on the vector format streak data is displayed. Can be created. For example, in the case of enlarging and displaying two times in the vertical and horizontal directions around a certain coordinate, each vertex coordinate of the stripe is drawn at a position twice as large as the distance before the enlargement from the enlarged display center point. Accordingly, the streak display unit incorporated in the WEB browser does not need to newly request the drawing data of the streak screen that has been enlarged / reduced to be displayed, so that the response of the enlarged / reduced display of the streak display screen is improved. .
