BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for monitoring an operating state of an electronic interlocking device .
[0002]
[Prior art]
FIG. 2A is a block diagram showing the signal monitoring device 10 used for analyzing the operation of the conventional electronic interlocking device according to function.
[0003]
The signal monitor device 10 is constituted by a known personal computer. Therefore, the output device has a display screen (not shown), and is configured so that a printer can be connected. The signal monitoring device 10 is connected to the electronic interlocking device main body a via the serial line L, and is configured to take in change information of the operation of the relay and the like from the electronic interlocking device main body a.
[0004]
Generally, the electronic interlocking device main body “a” does not have an internal clock and is configured so that processing can be performed at a predetermined constant cycle such as 100 ms or 200 ms. On the other hand, the signal monitoring device 10 is configured to capture change information from the electronic interlocking device main body a based on a clock signal per second of the internal clock 10a. Then, the captured information is subjected to editing processing for attaching sequence data (sequence No.) by the editing processing circuit 10b, and then stored in the memory 10c.
[0005]
FIG. 2B shows a part of an example in which the information stored in the memory 10c is output by a printer when necessary, for example, when searching for a failure or confirming an operation sequence. Here, change information of the electronic interlocking device main body a at 10:10:01 on June 1, 1998 (98/06/01 10:10:01) is shown, and 8E, 8F, 90 and 91 are Indicates the sequence number. Further, the uppermost part of the printout will be described. The relay of the route name 1R is “1” on the top at the above-described time. In this printout, “0” indicates that the relay is falling.
[0006]
[Problems to be solved by the invention]
However, since the conventional signal monitoring device can output only the change information per second regulated by the internal clock, it is inconvenient to check the change state during the second. .
[0007]
For example, when the periodic processing time (scan time) of the electronic interlocking device main body is 200 ms, since 5 scans are displayed as one change, it is difficult to check at which stage of 1 second the change has occurred. Met.
[0008]
In order to eliminate such inconvenience, it is conceivable to shorten the information capture time interval in the signal monitoring device, but if the information capture time interval is shortened in this way, a new processing load increases. Problems will occur.
[0009]
The present invention, which was made to solve the above drawbacks, and its object is to be output from the signal monitoring device changes information of the operation of the relay or the like with an accuracy of scan time of the electronic interlocking device body An object of the present invention is to provide an operation state monitoring device for an electronic interlocking device that can be used .
[0010]
[Means for Solving the Problems]
This onset Ming, in order to achieve the above object, the uptake based on the time information of the internal clock of the change information from the electronic interlocking device body at signal monitoring apparatus, the captured change information, this additional sequence information after the editing processing for, stored in the memory, the operating condition monitoring apparatus of an electronic interlocking device that outputs to a display screen or printer as needed information stored in its memory, in the electronic interlocking device body comprises means for adding a cyclic counter information according to the periodic processing of the electronic interlocking device main body to the change information, in the signal monitoring device, wherein the change information及BiAmane life counter information retrieved from the electronic interlocking device body And means for performing an editing process for adding sequence information to the time information of the internal clock at the time of the capture, and the editing process Means for storing information in the memory of after, when to output the information stored in said memory, and means for specifying a time and subject relays want to output the internal clock corresponding to the specified time time information and change information in the specified target relay, the periodic counter information and sequence information is characterized by comprising a means for outputting read from the memory.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The operation state monitoring device for an electronic interlocking device according to the present invention comprises an electronic interlocking device body a and a signal monitoring device 1. FIG. 1A is a block diagram illustrating the signal monitoring apparatus 1 according to one embodiment, classified by function.
[0012]
The signal monitoring device 1 is configured by a known personal computer, and has an unillustrated display screen as an output device so that a printer can be connected. The signal monitoring device 1 is connected to the electronic interlocking device main body a via the serial line L, and is configured to take in change information of operations such as relays from the electronic interlocking device main body a.
[0013]
The electronic interlocking device main body a is configured to be able to perform processing at a constant cycle of 200 ms. From the electronic interlocking device main body a, change information and cycle counter information can be sent to the signal monitoring device 1.
[0014]
The signal monitoring device 1 uses the edit processing circuit 1b to generate sequence data (sequence No.) based on the clock signal per second of the internal clock 1a and the information (change information and cycle counter information) from the electronic interlocking device main body a. After performing the editing process for attaching, it can be stored in the memory 1c.
[0015]
FIG. 1B is an example of a state in which information stored in the memory 1c is output. This output can be performed via a display screen or a printer (not shown) provided in the signal monitor device 1.
[0016]
This information is output by designating the time (time) at which a fault search or operation sequence is to be confirmed and the target relay via an input device (not shown) such as a keyboard or a mouse. In FIG. 1B, relays 1R to 54T are designated, and 10:10:01 is designated as the analysis time (point X) (10:10:01). Of course, this analysis time can be scrolled via the input device.
[0017]
In FIG. 1B, 1R is a route name, 1RZ is a route check, 1RAS is an approach lock, 52TRS is a right lock of the track circuit 52, 1RH is a signal display, 52T is a track circuit 52, and 1RAT is a track circuit. 1R and 54T indicate track circuits, and the rising portion of the time chart means “1” (upward), and the falling portion means “0” (falling). Further, 0.2, 0.4, 0.6, and 0.8 between the times (X point to X point + 1) given by the internal clock 1a are based on the period counter information received from the electronic interlocking device main body a. This corresponds to a period (200 ms). Among the relays described above, 1R to 1RAT are relays that have changed between 10:10:01 (X point) and 10:10:02 (X point + 1).
[0018]
Now, for example, when attention is paid to the relay 1RAS, the sequence number of the relay 1RAS is 8F in the editing processing circuit 1b (the sequence number is 8E, 8F, 90, 91, 97, The change point of the relay 1RAS is X point + (8F-8E) × 0.2, 0.2 seconds after the X point, that is, 10: 10: 1.2. Become.
[0019]
As is clear from the time chart of FIG. 1 (b), the operating state of each relay 1R to 54T during one second between 10:10:01 and 10:10:02 becomes clear at a glance, and the detailed operating state can be understood. By this, it can contribute to the trouble countermeasure after that.
[0020]
If the operation state of each of the conventional relays 1R to 1RAT is described with reference to FIG. 1B, the relays 1R to 1RAT are all displayed at the same time at the point X of 10:10:01. The Therefore, it was necessary to estimate the relationship between the operating states between relays from the sequence number.
[0021]
