Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm monitoring system for monitoring alarms generated in a plurality of monitored devices.

[0002]

2. Description of the Related Art Conventionally, in an alarm monitoring device for monitoring alarms generated by a plurality of monitored devices, when an alarm occurs frequently, a management network becomes congested and the alarm is monitored. The device may not be able to recognize the generated alarm.

Therefore, the monitored device and the monitoring device are connected by using two systems, and an alarm generated by the monitored device is notified to the monitoring device using only one or both systems. A monitoring device is used.

[0004]

Among the above-described alarm monitoring systems, in the case where an alarm is notified using one system, originally, the monitored device uses one address of the monitoring device to which the notification is sent. Since only the specified monitoring device can be specified, the system cannot operate if the specified monitoring device fails. Therefore, a method has been considered in which a virtual address common to two monitoring devices is provided on software, and an alarm is notified to the virtual address to stabilize the system. However, since the software components that can make such settings are limited, the system design requires
There is a problem in that there is a limitation in parts procurement.

In the case where an alarm is notified using both of the two systems, the alarm is normally notified using only the current system in the working / standby configuration, so there is no problem.
In the redundant switching method, even when the working is normal, if an error occurs in the network in the working / standby communication, both systems are operated as working. In that state, if an alarm is notified using both systems, an alarm is simultaneously notified to the monitoring device using the two systems, and the monitoring device collects and displays information using the originally desired system. There is a problem that it cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional technology, and aims to disperse alarm notifications when the system becomes congested due to frequent alarms. It is an object of the present invention to provide an alarm monitoring method capable of selecting a monitoring device that can perform the notification according to the content of the alarm.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an alarm system, wherein a plurality of monitoring devices and a plurality of monitored devices are connected via a network, and an alarm generated by the plurality of monitored devices. Is an alarm monitoring method of notifying a predetermined monitoring device of the plurality of monitoring devices, wherein each of the plurality of monitored devices is provided with an alarm for each abnormality content detected by the monitored device. An alarm allocating unit for allocating the alarms, and detecting, with a predetermined priority, the presence or absence of a failure of a plurality of monitoring devices serving as predetermined notification destinations for each of the alarms distributed by the alarm allocating unit. A monitoring unit that notifies the alarm to the monitoring device having the highest priority among the monitoring devices that do not have the priority.

[0008] Further, the invention is characterized in that a plurality of the fault detecting units are provided for each of the alarms distributed by the alarm distribution unit.

The alarm distributed by the alarm distribution unit is compared with the alarm that is being notified to the monitoring device, and only when the two are different from each other, the alarm distributed by the alarm distribution unit is compared with the alarm detection unit. The fault detection unit notifies the alarm output from the alarm management unit to the monitoring device having the highest priority among the monitoring devices in which no fault has occurred. It is characterized by the following.

[0010] Further, the invention is characterized in that a plurality of the alarm management units are provided for each of the alarms distributed by the alarm distribution unit.

[0011] Further, the present invention is characterized in that the fault detecting unit does not detect the presence or absence of a fault in another monitoring device when no fault occurs in the monitoring device with the highest priority. In addition, a notification destination of an alarm generated in the monitored device is determined in advance by assigning a priority to each content of the alarm, and when an alarm is generated in the monitored device, a notification destination of the monitoring device is set. It is characterized in that the presence or absence of a failure is detected and the alarm is notified to the monitoring device having the highest priority among the monitoring devices in which no failure has occurred.

(Operation) In the present invention configured as described above, when an alarm is detected in the monitored device, the alarm is notified to the monitoring device via the management network. If provided, a monitoring device to be notified is determined in advance, and the monitoring device is given a priority for determining the order of alarm notification, and an alarm is notified according to the priority.

[0013] The detected alarms are sorted for each type of abnormality by the alarm sorting unit and sent to the fault detecting unit. In the fault detection unit, the presence or absence of a fault in the monitoring device
It is detected according to the priority given to the monitoring device. If no fault has occurred in the monitoring device with the highest priority, the alarm is notified to the monitoring device with the highest priority. On the other hand, if a failure has occurred in the monitoring device with the highest priority, the notification destination of the alarm is the monitoring device with the second highest priority, and the presence / absence of a failure in the monitoring device is detected. If not, an alarm is notified to the monitoring device.

In the alarm management section, the alarm allocated by the alarm allocation section is compared with the alarm currently being notified to the monitoring device. Only when the two are different from each other, the alarm allocated by the alarm allocation section is compared. Is sent to the failure detection unit, thereby preventing the same alarm from being notified to the monitoring device in a repeated manner.

As described above, the monitoring device of the notification destination is determined with a priority for each alarm that has occurred, and the presence or absence of a failure in the monitoring device of the notification destination is detected. The alarm is notified to the monitoring device based on the above, so that the distribution of the alarm notification can be distributed according to the state of the system.
