Device Management System and Maintenance Work Method Using the System

A device management system including:

• a state detection unit configured to detect a state of each steam controller in a plant of interest;
• an input unit configured to input detection information from the state detection unit;
• and
• a state determination unit configured to effect determination of whether the state of a target steam controller is normal or not;
• for each steam controller in the plant of interest, device identification information for identifying the each steam controller being set;
• the state detection unit being configured to input the detection information including the corresponding device identification information to the input unit;
• wherein the device management system comprises:
• a storage unit which stores, in advance and in correlation with the device identification information set in each steam controller, location information indicating a location of each steam controller in the plant of interest, the storage unit further storing in advance work patterns for the steam controller according to a classification based on a device type and an installation state of the steam controller;
• a data extraction unit configured to extract from the storage unit the location information from the device identification information based on the detection information and to extract also a corresponding work pattern from the device type and the installation state specified from the device identification information, for a work-target device comprised of a steam controller whose state is determined as being not normal by the state determination unit;
• and
• a work information generation unit for generating work information consisting of the extracted location information and work pattern for the work-target device.
