Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention always monitors the status of a monitoring target device installed in a remote place to detect the occurrence of an abnormal situation, and detects a sign of the abnormality to accurately determine the timing of the malfunction. The present invention relates to a remote centralized monitoring system that can predict and prevent occurrence of an abnormality before it occurs.

[0002]

2. Description of the Related Art In order to monitor an object to be monitored installed in a remote place, a monitoring sensor which outputs a signal corresponding to the state of the object to be monitored in units of minutes and hours is conventionally provided. By transmitting a signal indicating whether the operation is normal or not to the centralized monitoring center via a public network or a dedicated line, an alarm unit provided in the centralized monitoring center is activated when an abnormality occurs to notify that the abnormality has occurred. Was like that.

However, such a conventional remote monitoring system has only a function of notifying the occurrence of an abnormality, so that it is necessary to perform a periodic inspection operation about once a month. Since it is impossible to avoid abnormalities even if regular inspections are performed, the frequency of inspections is usually increased to suppress the occurrence of abnormalities. However, it is almost impossible to completely avoid abnormalities caused by aging.

Therefore, conventionally, the service life of each device has been predetermined in order to suppress the occurrence of abnormalities due to the deterioration with time while increasing the inspection frequency. And even if the equipment whose service life has passed can be used, it is necessary to replace it regularly even if it is in a usable state, so that unnecessary costs were prevented to prevent the occurrence of abnormalities, but an accurate preventive effect can always be obtained. I couldn't say.

SUMMARY OF THE INVENTION The present invention constantly monitors the status of a monitoring target device installed in a remote place to detect the occurrence of an abnormal situation, and detects a sign of the abnormality to determine the timing of the malfunction. It is an object to accurately predict and prevent the occurrence of abnormalities.
