Abstract

PURPOSE:To provide a monitoring device whereby a telegraphic message where the name of a device to be monitored and present fault information are written is received from N devices to be monitored at every fault occurrence so as to be stored in a storage device and fault conditions in the device to be monitored where a fault occurs at a latest time except the device to be monitored which is displaying the present fault conditions can be quickly displayed. CONSTITUTION:A system is constituted by providing a time table 13 writing a reception time in the rows of the respective N devices to be monitored 1-N, a writing means 14 which writes time when the telegraphic message is received, permits the writing storage device 11 to store it and also writes time in the row of the time table 13 and a selecting means 15 which retrieves the time table 13, obtains the device to be monitored corresponding to the latest time, obtains the telegraphic message of the device to be monitored from the storage device 11 and gives it to a display part 12 at the time of displaying the fault conditions in the device to be monitored where the fault occurs at the latest time within the devices to be monitored except the device to be monitored where the present fault conditions is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a monitored device name and current fault information for each fault occurrence from a large number of monitored devices such as an automatic switching device, a relay device, and a multiplexer. Receive the written message, store it in the storage device,
A monitoring device that passes the stored fault information to the display unit and displays it
The present invention relates to a monitoring device that enables quick retrieval and display of past fault information.

2. Description of the Related Art FIG. 4 is a block diagram of a main part of a conventional monitoring system. In FIG. 4, the transmission device (monitored device) 1
4 to N, the transmission device in which the failure occurs, the transmission device name and the transmission device name are displayed as shown in FIG.
It is possible to indicate which kind of failure has occurred out of n kinds of failures and which kind of failure has not occurred by setting the allocation bit in n bits to 1 or 0.
Write a corresponding item in a telegram having a bit Monitoring device 4
Send to 0 '.

In the monitoring device 40 ', the received electronic message is stored in the same hard disk 11', and the latest electronic message,
That is, the PC interface 21 indicates which item of the n fault types of which transmission device is currently faulty.
It is sent to the display unit 12 of the personal computer 30 'through the display and displayed.

Reference numerals 22 'and 25' are ROMs for storing various programs, and 24 'is a hard disk.

[0005]

However, if an attempt is made to display the failure status of a transmission apparatus that has a failure at the latest time, other than the transmission apparatus that is currently displaying the failure status,
From the telegrams stored in the hard disk 11 ', in the transmission device other than the transmission device that is displaying the failure status,
The one that received the latest electronic message is searched and the electronic message is displayed on the display unit 1 of the personal computer 30 ′ via the personal computer interface 21.
However, there is a problem that it takes a long time to search because it is sent to 2 and displayed.

It is an object of the present invention to provide a monitoring device capable of promptly displaying the failure status of a monitored device having a failure at the latest time, other than the monitored device currently displaying the failure status.

[0007]

FIG. 1 is a block diagram showing the principle of the present invention. As shown in FIG. 1, N monitored devices 1 to
In the monitoring device that receives the name of the device to be monitored and the electronic message in which the current failure information is written from the N every time a failure occurs, stores it in the storage device 11, and passes the stored failure information to the display unit 12 for display. A time table 13 for writing the reception time into each of the monitored devices 1 to N, a time at which the electronic message is received is written in the electronic device and stored in the storage device 11, and the time is written in the corresponding line of the time table 13. Writing means 14
In order to display the failure status of the monitored apparatus in which a failure has occurred at the latest time among the monitored apparatuses other than the monitored apparatus whose failure status is currently displayed, search the time table 13 The monitored device corresponding to the latest time is obtained, the telegram of the monitored device is obtained from the storage device 11, and the display unit 1
It is configured to include the selection means 15 for transferring to the second.

[0008]

According to the present invention, among the monitored devices other than the monitored device whose failure condition is currently being displayed, when the failure condition of the monitored device having the failure at the latest time is displayed,
The selection means 15 searches the time table 13 for the monitored device corresponding to the latest time, obtains the message of the monitored device from the storage device 11 and transfers it to the display unit 12 for display. Time will be shortened, and it will be possible to display quickly.

[0009]

FIG. 2 is a block diagram of a main part of a monitoring system according to an embodiment of the present invention, and FIG. 3 is a flow chart for retrieving a message of another latest transmission apparatus according to the embodiment of the present invention.

2 is different from the conventional example of FIG. 4 in that the electronic message received from the transmission device is added with the reception time as shown in FIG. The ROM 22 is a writing means 14 for writing the reception time in the corresponding column of the time table.
2B and the transmission devices 1 to 1 as shown in FIG.
The hard disk 24 of the personal computer 30 is provided with a time table for writing the reception time in the row corresponding to N, and the ROM 25 of the personal computer 30 is provided with the selecting means 15 described below.

FIG. 3 is a flowchart of the selecting means 15, and a search for the latest electronic message of another transmission device will be described with reference to FIG. In step 1, N = NO ₀ of the transmission device
1 and the minimum time difference (hereinafter referred to as TMDIFF) is
The value is set to an unacceptable large value and the process proceeds to step 2.

Since the last transmission device is not NO ₀ in step 2, the process proceeds to step 3 and N =
The time of 1 is acquired, and the process proceeds to step 4. In step 4, the size of the time of the transmission device selected last time (hereinafter referred to as PRTIME) and the currently acquired time (hereinafter referred to as TIME) are compared. If TIME is small and the time is old, the process proceeds to step 5 and PRTIME If the value obtained by subtracting TIME is smaller than TMDIFF (it is always small at the beginning), proceed to step 6 and TMDIFF = PRTIME-
TIME, and NO ₀ of the transmission device at that time is M,
In step 7, M is incremented and the process returns to step 2.

In step 4, PRTIME is changed to TIME.
When it becomes smaller, the process proceeds to step 7, and when TMDIFF becomes smaller than (PRTIME-TIME) in step 5, the process proceeds to step 7.

The above operation is repeated until NO ₀ of the transmission device becomes N, and in step 8, from the NO ₀ of the transmission device having the minimum time difference obtained in step 6, the hard disk 11 of FIG.
The electronic message stored in is retrieved and sent to the display unit 12 of the personal computer 30 of FIG. 2 for display.

Of course, when it is desired to display the fault of another transmission device in which a fault has occurred at the new time, if PRTIME is set to the time selected this time, it can be retrieved and displayed using the flowchart of FIG.

[0016]

As described in detail above, according to the present invention, it is possible to quickly display the failure status of a transmission apparatus having a failure at the latest time, other than the transmission apparatus currently displaying the failure status. .
