Abstract

An insulation monitoring system as a remote monitoring system comprises an insulation monitoring terminal as a remote monitoring terminal that monitors a facility and a terminal management server connected to the insulation monitoring terminal via a network. The terminal management server monitors the operational status of the insulation monitoring terminal by receiving an operation verification signal transmitted from the insulation monitoring terminal. The insulation monitoring terminal includes detection unit for detecting abnormalities in a power unit, extraction unit for extracting representative values from the detection results obtained by the detection unit, and operation verification signal transmission unit for transmitting an operation verification signal including the representative values extracted by the extraction unit to the terminal management server at regular time intervals.

Claims

1. A remote monitoring system comprising:

a remote monitoring terminal monitoring a facility; and

a terminal management server connected to said remote monitoring terminal via a network, said terminal management server verifying the operational status of said remote monitoring terminal by receiving an operation verification signal from said remote monitoring terminal, wherein

said remote monitoring terminal comprises;

detection unit for detecting abnormalities in the facility;

extraction unit for extracting representative values from detection results obtained by said detection unit; and

operation verification signal transmission unit for transmitting said operation verification signal including said representative values extracted by said extraction unit to said terminal management server at regular time intervals.

2. The remote monitoring system according to claim 1, wherein

said terminal management server comprises:

storage unit for sequentially storing said representative values included in said received operation verification signal; and

display unit for displaying said representative values stored in said storage unit.

3. The remote monitoring system according to claim 2, wherein

said storage unit stores information concerning an administrator associated with said remote monitoring terminal,

said terminal management server further comprises:

selection unit for selecting said representative values of said remote monitoring terminal associated with a specific administrator from said storage unit; and

distribution unit for distributing said representative values selected by said selection unit to the associated administrator.

4. The remote monitoring system according to claim 1, wherein

said terminal management server comprises report unit for notifying the administrator of the abnormality in said remote monitoring terminal when said terminal management server does not receive said operation verification signal from said remote monitoring terminal within a predetermined period of time.

5. The remote monitoring system according to claim 1, wherein

said representative values are a maximum value and a minimum value, obtained from the detection results within a predetermined period of time, and the times at which the maximum value and minimum value are detected.

6. A remote monitoring terminal connected to a terminal management server via a network and transmitting an operation verification signal to said terminal management server to report its own operational status, comprising:

detection unit for detecting abnormalities in a facility;

extraction unit for extracting representative values from the detection results by said detection unit; and

operation verification signal transmission unit for transmitting said operation verification signal including said representative values extracted by said extraction unit to said terminal management server at regular time intervals.

7. A remote monitoring terminal control program enabling a computer that is connected to detection unit for detecting abnormalities in a facility to operate as:

extraction unit for extracting representative values from the detection results obtained by said detection unit; and

operation verification signal transmission unit for transmitting an operation verification signal including said representative values extracted by said extraction unit to said terminal management server at regular time intervals.
