Abstract

PURPOSE:To make alarm transfer processing speed fast and also to early detect the abnormal state of a system to be monitored in an alarm transferring device when a priority is given to an alarm to be collected. CONSTITUTION:A queue sorting part 3 sorts the alarm collected by an alarm collecting part 5 to a priority classification queue 2 which is corresponding by the classification of the priority in accordance with the priority which is designated by a priority deciding part 4. Unless there is room in the applying queue, the alarm of the effect is generated and storage is executed in the priority classification queue 2 which is one-stage higher in the priority.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm transfer device, and more particularly to an alarm transfer device when priority is given to an alarm to be collected.

[0002]

2. Description of the Related Art As a conventional alarm transfer device, for example,
As shown in FIG. 2, there is a system in which the alarms collected by the alarm collecting unit 5 are stored in the queue 6 in the order in which they are collected without considering the alarm priority, and the alarms are transferred from the alarm transfer unit 1.

Further, as shown in FIG. 3, there is one queue 6, and a queue reorganization unit 7 for rearranging the alarms in the queue 6 according to the priority designated by the priority determination unit 4 is provided. There has been a method of transferring from the transfer unit 1 in order from the highest priority.

[0004]

In the case of the former alarm transfer apparatus of FIG. 2, however, the former alarm shown in FIG. 2 has a problem that an alarm having a high priority is not easily transferred when the alarm occurs frequently. ..

In the latter case of FIG. 3, the high-priority alarms are transferred first, but queue rearrangement takes time, the processing speed becomes slow, and low-priority alarms frequently occur. However, there was a problem that the state could not be grasped.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an alarm transfer device that does not require queue rearrangement and increases the processing speed.

[0007]

In order to achieve the above object, an alarm transfer apparatus according to the present invention comprises a plurality of priority queues for storing alarms according to priority, an alarm collector for collecting alarms, and
A priority determination unit that determines the priority of the alarm, a queue distribution unit that stores the collected alarms in the corresponding priority-based queue according to the priority designated by the priority determination unit, and a descending order of priority. An alarm transfer unit for extracting and transferring alarms from the priority-based queue is provided.

Then, if necessary, the queue distribution unit has a storage function of creating a new alarm to that effect and storing the new priority in the priority-specific queue when the priority-specific queue is not empty. It is as a configuration.

[0009]

According to the alarm device having the above-mentioned configuration, the collected alarms are distributed to a plurality of priority-based queues according to priority, and the queues need not be rearranged.

Further, when the queue allocating unit creates a new alarm when there is no empty queue for the corresponding priority and stores it in the queue whose priority is one step higher, the state is grasped even if low-priority alarms are issued frequently. To be done.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an alarm transfer device according to an embodiment of the present invention.

In the figure, 2 is a plurality of priority queues for storing alarms by priority, 5 is an alarm collecting unit for collecting alarms, and 4 is a priority determining unit for determining the priority of alarms.

Reference numeral 3 denotes a queue allocating unit, which stores the alarms collected by the alarm collecting unit 5 in the corresponding priority-based queue 2 according to the priority designated by the priority determining unit 4. When there is no empty queue according to priority, the queue allocator 3 creates a new alarm to that effect and sets the priority to 1
It has a storage function to store in higher priority queues.

Reference numeral 1 denotes an alarm transfer unit for extracting and transferring alarms from the priority queue 2 in descending order of priority.

Therefore, according to the alarm transfer device of this embodiment, the alarm collection unit 5 collects external alarms and transfers them to the queue distribution unit 3. The queue distribution unit 3 stores the passed alarm in the priority-based queue 2 of the corresponding priority according to the priority information from the priority determination unit 4.

At this time, when there is no empty priority queue, the queue allocating unit 3 selects a queue having a priority one step higher and stores an alarm indicating that there is no empty lower queue. .. After this, a certain number of alarms to the lower queue are unconditionally discarded.

The alarm transfer unit 1 takes out the alarms from the priority-based queue 2 in order of priority and transfers the alarms to the host system.

[0018]

As described above, according to the alarm transfer apparatus of the present invention, the alarms are handled independently by priority by providing a plurality of priority-based queues and a queue allocating unit. It becomes unnecessary and processing speed becomes faster.

Further, if a new alarm is stored in a queue whose priority is one step higher when there is no empty queue, when a low-priority alarm is issued frequently, that state is transferred with a higher priority. Therefore, there is an effect that the abnormal state of the monitored system can be detected at an early stage.
