Remote monitoring system, remote monitoring terminal and remote monitoring terminal control program

摘要

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.
