Description

  The present invention relates to a display control panel, a train operation management system, and a track circuit display method.

  On a display control panel, which is a terminal device of an electronic interlocking device used to ensure the safety of a station premises in a railway or the like, for example, as shown in Patent Document 1 below, a wiring schematic diagram showing the shape of a track is displayed. . This wiring diagram is graphically displayed for each track circuit in which the route is divided into a plurality of sections so that the operator can visually grasp the route state, and the display color of the opened track circuit is changed from red to green. .

  Moreover, the following patent document 2 discloses a train operation management system having a function similar to that of the display control panel, and the train operation management system displays an operation status for displaying the status of the station platform according to the movement of the train. A screen is used. On this operation status screen, the above wiring schematic diagram is displayed, and the color change by the train existing line on the wiring schematic diagram is performed (the track configuration is yellow, the train non-existing line is blue, and the train existing line is red).

Japanese Patent Laid-Open No. 04-197876 (lower right of item 5) JP 08-133305 A (paragraph 0021, FIG. 2, etc.)

  In the prior art disclosed in Patent Document 1, the track circuit when the route is opened is displayed in green, and the track circuit when not opened is displayed in red. In the prior art disclosed in Patent Document 2, the track circuit is displayed when the track is opened. Yellow, the track circuit when the train is present is displayed in red, and the track circuit when the train is not present is displayed in blue. As described above, the conventional technology responds by adding different colors when information to be displayed on the display control panel or the operation status screen increases.

  However, in these conventional techniques, since the color display of the track circuit is limited to one color at a time, it is possible to display only one-line route state information and route control information at a time. For example, if the color of the track circuit is assigned to red when the train is present, white when the train is not present, orange when the route is opened, cyan when the track is closed, the conventional display control panel uses the color when the train is present (red ) Is displayed with the highest priority. For example, when track closing (cyan) is set to perform interlocking inspections, a specific vehicle such as a maintenance car is placed on the closed track (cyan). When a train is present, the color of the track circuit on the wiring diagram is changed from cyan to red. Therefore, in the wiring schematic diagram, it becomes impossible to visualize the route control information that the track is closed.

  Also, in the display control panel, route opening has priority over line closing, so when a route on the wiring schematic is closed (cyan), if a part of the route is changed to route opening, it was closed A part of the color (cyan) of the route is repainted to the color of the route opening (orange), and the closed route is displayed in a mixed state of two colors. Therefore, it is difficult for the operator to see and the operator is confused.

  Thus, in the prior art, since the color of each track circuit is displayed in a single color, the color of the track circuit reflecting the route state information and the route control information is changed to another color, so that the operator operates the current operation. There was a problem that it was impossible to immediately grasp the situation (route state information) and the command content from the operation command station (route control information).

  The present invention has been made in view of the above, and obtains a display control panel, a train operation management system, and a track circuit display method capable of immediately grasping the operation status and the command content from the operation command center. For the purpose.

  In order to solve the above-described problems and achieve the object, the present invention makes a setting request for a plurality of field devices including a traffic light, a turning machine, and a track circuit, and a wiring configuration of a track on which a train travels. A display control panel for displaying a wiring schematic diagram reflecting the installation position of the traffic signal, and uniquely identifying the track circuit and a plurality of track circuit states including a train existing line state in the track circuit and the track circuit state A track circuit information table in which a plurality of track circuit colors are associated, track information indicating whether or not a train is on the track circuit, track control information for controlling the route of the train, and the wiring schematic diagram Based on the reflected wiring schematic data and the track circuit information table, the track circuit color is selected for each track circuit, and a combination of the selected track circuit color and track circuit is used as track circuit color data. A track circuit color data generation unit for outputting, and a display unit that displays a plurality of track circuit colors without overlapping each track circuit in the wiring schematic diagram based on the track circuit color data. And

  According to the present invention, since a plurality of track circuit colors are displayed on each track circuit on the schematic wiring diagram without overlapping, it is possible to immediately grasp the operation status and the command content from the operation command center. There is an effect.
