BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection monitor for displaying an actual interlocking logic processing state of an electronic interlocking device adopting a connection processing method in a relay connection diagram.

[0002]

2. Description of the Related Art For example, in a stop yard or a vehicle depot,
In order to safely and reliably drive and replace vehicles, etc., a chain is provided between on-site equipment such as traffic lights and point machines, and on-site equipment is automatically operated according to the route setting from the signal handling place. An interlocking device that controls the state is used.

As such an interlocking device, there has been a relay interlocking device that forms an interlocking logic using a relay frame composed of a large number of electromagnetic relays. However, with the recent development of electronics, the interlocking logic has been softwareized. An electronic interlocking device using a microcomputer has been put to practical use. In addition, there is an electronic interlocking device of a wire connection processing type in which a connection diagram of a relay constituting an interlocking logic of a relay frame in the relay interlocking device is made into software and controlled by a microcomputer.

[0004]

By the way, in the conventional electronic interlocking device of the connection processing method, the operation result of the on-site equipment based on the command from the signal handling place is determined by the traffic signal on the premises installed at the signal handling place or the turning point. It can be confirmed by the linear display on the control panel that shows the arrangement status of the field equipment such as one machine, but this can only be confirmed as a result, and the processing process in the electronic interlocking device (relay contact state, energized state in the wiring diagram) It was difficult to confirm. For this reason, when a problem occurs in the operation state of the field device, there is a problem that it takes time to find the cause.

In the case of a relay interlocking device, it is possible to check the operation of the relay constituting the relay rack by actually checking the operation state of the relay and visually checking the operation with a connection diagram. In the device, such confirmation cannot be performed, and there is a problem that it is difficult for the user to handle. Therefore,
The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to visually recognize an interlocking logic processing process in an electronic interlocking device of a connection processing method.

[0006]

Therefore, in the connection monitoring device of the present invention, as shown in FIG. 1, the connection diagram data of the relay stored in the first storage medium in advance based on the interlocking logic of the electronic interlocking device. First data reading means to be read, display means for displaying a connection diagram of a relay based on the connection diagram data read by the first data reading means, and execution based on a field device operation command input to the electronic interlocking device. A second data reading means for reading the processing data from a second storage medium for storing the processing data of the interlocking logic, a display of a relay contact state of a wiring diagram displayed on the display means, and a display of an energized state of the wiring diagram, Display control means for variably controlling according to the processing data read by the second reading means.

[0007]

According to this configuration, the status of the interlocking logical processing actually executed in the electronic interlocking device is displayed in the connection diagram of the relay, so that the logical processing process can be visually checked, and the time of debugging or occurrence of an error can be confirmed. Sometimes it is easy to analyze the cause of the abnormality. Further, since the basic relay connection diagram data constituting the interlocking logic is read from the ROM, the RO associated with the interlocking logic change is changed.
Version control of M is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows the configuration of an embodiment of the connection monitoring device according to the present invention. In FIG. 2, a signal handling place A displays a premises linear diagram or the like showing an arrangement state of on-site equipment 3 such as a traffic signal and a point machine provided at a site C on which a yard track is laid. A control panel that variably controls the display state of field devices according to the train operation state, a display control unit 1 that includes a dedicated keyboard, and the like, and a connection monitor device 10 that is a feature of the present embodiment described later are installed.

In the equipment room B, an interlocking processing unit 2 connected to the display control unit 1 by an optical cable or the like is installed.
The interlocking processing unit 2 includes a microcomputer or the like, and according to a field device operation command from the display control unit 1, a connection diagram of a relay stored in advance in a ROM or a floppy disk (FD) as a first storage medium. The on-site equipment 3 is driven and controlled by the interlocking logic based on. Then, the interlocked logical processing data executed in accordance with the field device operation command is stored in a RAM as a second storage medium. The operation command of the field device can be issued automatically by a commander using a keyboard or automatically according to a program stored in advance.

The connection monitor device 10 includes a display control unit 11 having a microcomputer.
And a display 12 as display means controlled by the display control unit 11. The display control unit 11 has a ROM in the interlocking processing unit 2.
The basic relay connection diagram data is read from the CPU 11 and the connection diagram is displayed on the display 11. Further, the processing data of the interlocking logic executed from the RAM in the interlocking processing unit 2 is periodically read out, and the display of the relay contact state in the connection diagram displayed on the display 12 and the display of the energization state in the connection diagram are performed. Variable display. Here, the display control unit 11
It has the functions of first data reading means, second data reading means, and display control means.

Next, the operation of the connection monitor 10 of the present embodiment will be described with reference to the flowchart of FIG. First, in step 1 (indicated by S1 in the figure, the same applies hereinafter), display of a main menu which can be performed by the connection monitor 10 is executed. In step 2, selection of a main menu is executed by mouse input.

In step 3, a menu (function) selected by mouse input is determined. here,
When the environment setting function is selected, the process proceeds to step 4 and the environment setting process is executed. In this environment setting process, a selection is made as to whether the basic wiring diagram data programmed in advance is read out from the ROM in the electronic interlocking device or read out from the floppy disk. When reading from a floppy disk, also specify the file name. When the process of step 4 is completed, the process returns to step 1 again. In step 2, menu selection is executed by mouse input, and if the monitor function of the connection diagram is selected, the process proceeds to step 5. If the end is selected, the flow ends.

In step 5, the connection diagram data is read from the ROM or floppy disk selected in step 4. In step 6, an input operation using a mouse is performed. If there is no input operation with the mouse, the determination in step 7 is no input, and the process proceeds to step 8, and if there is an input, the process proceeds to step 10.

In step 8, the RAM of the electronic interlocking device side
Of the processing data of the executed interlocking logic stored in the memory. In step 9, the relay contact display and the energization state display of the connection diagram read out from the ROM or the floppy disk and displayed on the display 12 are displayed.
The data is rewritten and displayed based on the processing data read in step 8.

Here, the connection diagram displayed on the display 12 shows the electrical connection state of each relay contact and the relay as shown in FIG. Then, based on the processing data associated with the execution of the interlocking logic processing, in the case of the configured relay contact, a contact display as shown on the upper side of the display 12 in FIG. 4 is displayed, and in the case of the unconfigured relay contact, The contact is displayed as shown on the lower side of the display 12 in FIG. Regarding the energized state, for example, as shown in FIG. 5, when a connection diagram is displayed such that the relay contact on the left side of the figure is configured and the next relay contact is not configured, the relay that is not configured is displayed. Since the contacts are energized, for example, they are displayed in yellow to indicate that electricity is flowing, and in the subsequent portions including the relays, the relays are not energized because no relay contacts are configured, and are, for example, white. By indicating that electricity is not flowing by displaying, the energized state in the connection diagram can be seen at a glance.

When the input operation with the mouse is performed and the determination in step 7 is input and the process proceeds to step 10, various processes corresponding to the input operation of the mouse are executed. The various processes include a scrolling process of the connection diagram displayed on the screen, an enlargement / reduction process, a connection search, and the like. In step 11, a determination is made as to whether or not monitoring has been completed. If monitoring is to be continued, the determination is NO, the process proceeds to step 8, and the display of the connection diagram is continued. On the other hand, if the monitoring has ended, the determination is YES and the process returns to step 1.

As described above, the interlocking logic processing state actually executed by the interlocking processing unit 2 of the electronic interlocking device is displayed on the display 12 in the form of a wiring diagram on the screen, so that the state of the relay contacts and the energization and connection of the wiring can be controlled. The de-energized state is clear at a glance, and even a user who has experience with the relay interlocking device can easily understand the electronic interlocking. In addition, it becomes extremely easy to analyze the cause of a failure when debugging or when a failure occurs. Further, in the present embodiment, the basic wiring diagram data is read from the ROM or the floppy disk. Therefore, even when new wiring diagram data is used due to a change in interlocking logic due to a diagram revision or the like, the display 12 is not used. Can be distinguished at a glance whether the data is new or old by looking at the connection diagram displayed in. Therefore, for example, when reading from the ROM, there is an advantage that the version of the ROM can be managed.
