FIG. 1 is a system configuration diagram according to the present invention. This system includes an interlocking device (11), a maintenance device (12), and ground equipment (for example, a traffic light, a switch, a track circuit, etc.).
The interlocking device (11) is installed in, for example, a device room in a station premises, and controls the ground devices (for example, traffic lights, switchboards, track circuits, etc.), and performs a train route configuration process, etc. It is.

The maintenance device (12) has a function of communicating with the interlocking device (11), and by performing setting of a simulation mode, a maintenance mode, a power failure area instruction, etc., to the interlocking device (11), the interlocking device This is a device for controlling the state of (11).
Here, the simulation mode means that the state data of the ground device in the interlock device (11) is operated (simulated) according to the control of the interlock device (11) in order to test the interlock device (11) and the ground device. In this mode, the interlocking device (11) itself performs editing.

The maintenance mode is a mode in which alarms due to abnormalities occurring during maintenance of ground equipment (for example, disconnection of a light bulb when replacing a traffic light) are suppressed (thus avoiding confusion during maintenance work).
The power outage area is an area that suppresses alarms and route setting due to a power outage in the station premises.

  FIG. 2 is a specific example of the internal configuration of the maintenance device (12). The maintenance device (12) communicates with the interlocking device (11) by the internal processing unit (100).

  List information of each ground device controlled by the interlocking device (11) is held as a ground device list information table (104). The ground device list information table (104) includes the name of each ground device and each ground device. Linking information (link information) based on the interlocking relationship between them is stored. The ground equipment list information table (104) may be in the security device as a database or may be outside the security device.

  The input unit (105) performs device selection, range specification, and the like for the processing unit (100) via the GUI (107). Specifically, for example, a pointing device represented by a mouse may be used.

  The display means (106) displays a list of ground equipment or a route map including the ground equipment via the GUI (107), and selects and operates the ground equipment in response to an instruction from the processing unit (100). Status display such as range specification is also performed. As a specific means, for example, a display represented by a display may be used.

The processing unit (100) includes a communication unit (101), a linked device extraction unit (102), and a duplicate device extraction unit (103).
The communication means (101) exchanges data such as ground device selection data and communication status with the interlocking device (11). For example, Ethernet (registered trademark) may be used.

The interlocking device extraction unit (102) uses the ground device selected by the input unit (105) as a key, refers to the ground device list information table (104), and holds the string held in the ground device list information table (104). The linked ground equipment is extracted based on the attached information (link information).
The duplicate equipment extraction means (103) extracts duplicate ground equipment from the ground equipment linked by the interlocking equipment extraction means (102) and the ground equipment within the range specified by the input means (105).

  FIG. 3 is a specific example of the list information of ground equipment based on the ground equipment list information table (104). Via the GUI, the ground device to be tested is selected from the list of ground devices with the cursor (21) (in the figure, the switch 11a is selected). In the list of ground equipment shown in FIG. 3, 1R and 2R are traffic lights, 11a and 11b are turning machines, 11a T, 11roT, 1RAT and 2RBT are track circuits, respectively. Previously, the ground equipment stored and held as a table instead of the operator determining the linkage (link) of the ground equipment from the route map and selecting each ground equipment from the list of ground equipment. By using the list information and the GUI, it becomes possible to perform operations easily and speedily.

  FIG. 4 is an example of the entire screen displayed by using the GUI. For example, (31) for traffic lights, (32) for turning machines, and (33) for track circuits. A route map is shown on the entire screen, and the traffic lights 1R and 2R of the ground equipment, the turning machines 11a and 11b, the track circuits 11iT, 11roT, 1RAT and 2RBT are displayed together. Thereby, selection of the ground equipment on a route map can be performed simply.

  FIG. 5 shows an example in which the traffic light 1R is selected with the cursor (41) via the GUI. When one of the ground devices is selected, the maintenance device (12) extracts the ground device linked (linked) to the selected ground device by the interlocking device extraction means (102), and this linked ground device Is displayed on the screen together with the selected ground device via the GUI.

  As a highlighting method, it is possible to display with different colors, different line types, different line thicknesses, display an animation, or change the font if accompanied by characters. In addition, instead of this highlighting, a display mode can be adopted in which the display of the ground equipment that is not the object is displayed lightly or darkly to distinguish it from the ground equipment that is the object by bright and dark display.

  In the example of FIG. 5, by selecting the traffic light 1R, as the ground equipment on the route map interlocking with the traffic light 1R, the turning machines 11a and 11b, the track circuits 11a T, 11ro T, 1RAT and 2RBT are selected. It is highlighted (in this case with a different color and thickness).

In addition, when specifying a range to be a target of the simulation mode or the maintenance mode, or when specifying a range for setting a power outage area, the operation can be performed via the GUI.
FIG. 6 is an example in which a test range is designated via the GUI for testing such as simulation in the simulation mode for the traffic light 1R highlighted in FIG. 5 and the ground equipment linked thereto. The test range is designated on the route map displayed on the display means (106) by the input means (105).

  As a designation method of the designated range (51), when designating in a rectangular shape as shown in the figure, the input means (105) is used to designate two points, for example, an upper left point and a lower right point. It suffices to surround the required range. By this operation, duplicate ground equipment is extracted by the duplicate equipment extraction means (103) from the ground equipment within the specified range and the previous traffic light 1R and the ground equipment linked thereto, and is highlighted as shown in FIG. In this case, they have different colors and thicknesses). Of course, instead of emphasis display, bright and dark display may be performed as described above.

  In addition, when making a circle a designated area (not shown), it is sufficient to indicate at least two points of the center point and the other end of the radius. In addition, various ranges depending on the location of the ground equipment on the target route map and the range of the designated area, such as specifying two points, outputting a line segment, and specifying a track circuit on the line segment An appropriate pattern may be adopted from the designated pattern.

Also, depending on the ground equipment, it may be linked to a wide range of other ground equipment, so use the above-mentioned range designation method to specify a range that excludes a wide area. It may be.
The maintenance device (12) displays a ground device to be used as a test, and tests the actually selected ground device with the interlocking device. By adopting the above selection and display mode, the maintenance device (12) is simplified. Can provide excellent operability for avoiding errors.

FIG. 7 is an example of a list of ground devices and association data between the ground devices. This is data in which the ground devices indicated by the arrow (61) are linked to each other. The linking method is performed based on a route connected on the track circuit.
