DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a monitoring device (monitoring system) according to the present invention will be described with reference to the drawings. FIG. 1 is a system diagram showing the configuration of an embodiment of a monitoring system according to the present invention and the contents of information processing in each configuration. Devices A201 and B to be monitored
The monitoring device 101 that monitors the device 202 includes an alarm transmission circuit (communication circuit) 3 with the device A201 and the device B202.
01 and 302 are connected. Monitoring device 101
Monitors the operation status of the device A201 and the device B202 and the communication state between the devices, and when the result of the monitoring shows that an abnormality is found, generates monitoring information based on the content of the abnormality and transmits the generated monitoring information to the communication line 303. Monitoring server 1 via
02.

Here, if the content of the recognized abnormality is a communication abnormality, the monitoring apparatus 101 should display the information in an alarm display when creating monitoring information (communication abnormality information) based on the abnormality. The communication abnormality information that has been repeatedly generated / recovered in a short period of time is set with a mask flag indicating that the information should not be displayed, and transmitted to the monitoring server 102 (FIG. 1). Specifically, as shown in FIG. 2, when a communication error occurs and recovery occurs in a certain device (FIG. 2), the monitoring device 101 measures a certain period of time from the recovery time. If the occurrence and recovery of the communication error are repeated again in the same device during this time counting process (FIG. 2), the monitoring device 101 determines that the error should be hidden (masked). Then, a predetermined flag of communication abnormality information corresponding to the communication abnormality is set and transmitted to the monitoring server 102. If a communication error occurs and recovers again in the same device after a certain period of time (see FIG. 2), the error is determined to be an error to be displayed as an alarm, and the flag is not set. Monitoring information is created and transmitted to the monitoring server 102.

When the monitoring server 102 receives the communication error information from the monitoring device 101, it records all the communication error information regardless of the state of the flag. Then, the monitoring server 102
Among the recorded communication error information, only the communication error information for which no flag is set, is transmitted to the monitoring base 103 such as a monitoring center.
To the alarm display terminal 104 via the communication line 304. When communication abnormality information is sent from the monitoring server 102, the alarm display terminal 104 performs a display to that effect. For example, the occurrence and recovery of a communication error are repeated in a short time in the device A201 of FIG.
In FIG. 2, if the occurrence and recovery of a communication error are not repeated in a short period of time, the alarm display terminal 104
Only the first occurrence / recovery of the communication abnormality information of the device A201 that has been restored is displayed, and thereafter, the communication abnormality information within a certain period is not displayed. On the other hand, all the communication abnormality information of the device B202 is displayed. Referring to FIG.
A process of adding a mask flag when the occurrence and recovery of a communication error are repeated in a short time in 201 will be described.

In the device A201, if a communication error occurs three times (S101, S121, S141) and the first and second communication errors are recovered (S111, S131), the occurrence of the communication error and the communication error All restoration information is transmitted to the monitoring apparatus 101 (S102, S11
2, S122, S132, S142). Monitoring device 101
When the first communication error occurrence information (S102) is received, the communication error occurrence information is transmitted to the monitoring server 102 (S103). The monitoring server 102 transmits the communication abnormality occurrence information (S104) to the alarm display terminal 104, and the alarm display terminal 104 displays the occurrence of the communication abnormality (S105).

When the monitoring apparatus 101 receives the first communication error recovery information (S112), it transmits the communication error recovery information to the monitoring server 102 (S113). Also, where
The monitoring apparatus 101 starts measuring a certain period of time for adding a mask flag. The monitoring server 102 transmits the communication error recovery information (S114) to the alarm display terminal 104, and the alarm display terminal 104 displays the recovery of the communication error (S11).
5).

Next, when the monitoring apparatus 101 receives the communication abnormality occurrence information (S122) during the counting of a certain period, the communication abnormality occurrence information (S123) is added with a mask flag (set). , To the monitoring server 102.
The monitoring server 102 stores only the communication abnormality occurrence information (S123) to which the mask flag is added in the storage device, and does not transmit the information to the alarm display terminal 104. Therefore,
The occurrence of a communication error is not displayed on the alarm display terminal 104 (S124).

Next, when the monitoring apparatus 101 receives the communication error recovery information (S132) during the counting of a certain period, the monitoring server 102 adds the communication error recovery information (S133) with the mask flag added thereto. Send to The monitoring server 102 stores only the communication abnormality restoration information (S133) to which the mask flag is added in the storage device, and does not transmit the communication abnormality restoration information to the alarm display terminal 104. Therefore, the alarm display terminal 104 does not display the communication error recovery (S13).
4).

Next, when the monitoring apparatus 101 receives the communication error occurrence information (S142) after the end of the clocking for a certain period,
The communication error occurrence information is transmitted to the monitoring server 102 without adding the mask flag (S143). Monitoring server 102
Transmits the communication error occurrence information (S144) to the alarm display terminal 10
4 and the alarm display terminal 104 displays the occurrence of a communication error (S145).

On the other hand, the business terminal 105 connected to the monitoring server 102 shown in FIG.
By accessing the monitoring server 102, the masked communication abnormality information can be referred to (see FIG. 1).

As described above, according to the present embodiment, the occurrence of a communication error occurring in the same device within a certain period of time /
A flag is added to the recovery information by the monitoring device, and the communication error information is masked by the monitoring server, so that the communication error information is prevented from being repeatedly displayed in a short time on the alarm display terminal at the monitoring base. Can be. However,
Since the masked communication abnormality information is also recorded in the monitoring server, it is possible to confirm this using the business terminal at the monitoring base.

[0018]

As described above, according to the present invention, even when a communication abnormality that repeatedly occurs / recovers in a short period of time occurs in an information transmission circuit or the like of a device to be monitored,
An alarm for occurrence / recovery of a communication error is not displayed until after a certain period of time has elapsed, so that the operator is not burdened with the confirmation action as compared with the related art.
