Abstract

PROBLEM TO BE SOLVED: To finely monitor an abnormal state and to judge the abnormality of a device beforehand by increasing the frequency of monitoring for the device of high alarm generation frequency in fixed time. SOLUTION: When three monitoring objects 2a-2c are present, as a normal monitoring processing, monitoring is performed once each in a fixed cycle to the monitoring objects 2a-2c. In a gathered result processing part 1, a generation frequency management part 1b controls a history management part 1a and the history management of the generation history of alarms gathered in the fixed cycle is performed for the monitoring objects 2a-2c in the history management part 1a. The frequency of the alarms obtained in the history management part 1a is stored in the generation frequency management part 1b, the decision part 1c of the frequency of monitoring obtained in the fixed cycle is controlled and the frequency of monitoring of the respective monitoring objects is proportionally divided in the descending order of the alarm generation frequency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-apparatus monitoring method and an in-apparatus monitoring apparatus in which there are a plurality of monitoring targets, for example, a plurality of packages in an apparatus, and the packages are monitored in order.

[0002]

2. Description of the Related Art In recent years, a device is often composed of a plurality of packages, and when the number of packages is large, it becomes difficult to identify a failure location. Therefore, the packages in the device are monitored at regular intervals and the monitoring is performed. From the result, the package is detected to be abnormal before it becomes a failure.

[0003]

However, such a conventional device has a problem that even if the reliability of a certain package gradually decreases, the reliability cannot be detected unless a failure occurs. It was

The present invention has been made in view of such a situation, and is intended to detect a decrease in reliability.

[0005]

In order to detect such a problem, the present invention is an in-apparatus monitoring method for performing in-apparatus monitoring at a constant cycle, and records the alarm occurrence frequency in the history from the in-apparatus monitoring result. By extracting the monitoring items with a high alarm occurrence frequency and increasing the number of alarm collections according to the alarm occurrence frequency, the alarm detection capability is enhanced. In addition, an alarm frequency management unit, which is a recording unit that records the alarm occurrence frequency in the history from the in-apparatus monitoring result, and an alarm collection that extracts the monitoring items with high alarm occurrence frequency and determines the alarm collection frequency according to the alarm occurrence frequency. And a monitoring frequency determination unit that is a frequency determination unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of the present invention. There are three monitoring targets 2a to 2c, and as a normal monitoring process, a constant cycle t is applied to the monitoring targets 2a to 2c. It is designed to monitor once during the period. In the collection result processing unit 1, the occurrence frequency management unit 1b controls the history management unit 1a to perform history management of the alarm occurrence history collected during the constant period t for the monitoring targets 2a to 2c. ing.

The number of alarms obtained by the history management unit 1a is stored in the occurrence frequency management unit 1b, and the occurrence frequency management unit 1b is based on the number of alarms of each monitoring target obtained during the fixed time T1.
Controls the monitoring frequency determining unit 1c to divide the monitoring frequency of each monitoring target in descending order of alarm occurrence frequency.

For example, during the time T1, the alarm generation history of the monitoring target 2a is twice, and the alarm generation history of the monitoring target 2b is 8 times.
Assuming that the alarm occurrence history of the monitoring target 2c is 0, the monitoring frequency determining unit 1c controls the occurrence frequency managing unit 1b to set a constant period t for the monitoring target 2b having a high alarm occurrence frequency.
Increase the number of times the time is monitored. At this time, the number of times of monitoring of the constant period t time is, for example, once for the monitoring target 2a and for the monitoring target 2a.
b is determined twice, and the monitoring target 2c is determined once. However,
Even if the alarm generation frequency is zero, the monitoring is performed at least once during the constant period t.

FIG. 2 shows the monitoring state before and after the occurrence frequency is changed. In the normal monitoring process, the monitoring target 2a is once and the monitoring target 2b is once during a fixed period t. The monitoring target 1c is monitored once. As a result, the time T1 elapses, and when the number of times of alarm occurrence described above has been obtained for each monitoring target, processing after the time T1 is performed. That is, a state is shown in which the monitoring target 2a is monitored once, the monitoring target 2b is monitored twice, and the monitoring target 2c is monitored once within a fixed period t1.

As described above, the abnormal state is finely monitored by increasing the number of times of monitoring for a device with a higher alarm frequency.

[0011]

As described above, according to the present invention, the number of times of monitoring is increased as the frequency of alarm generation increases in a certain period of time. Therefore, it is possible to finely monitor an abnormal state, and to monitor the apparatus before a failure occurs. It is possible to judge an abnormality, increase the power of alarm generation, prevent a failure, and improve reliability.
