Abstract: An equipment monitoring system includes an abnormality/abnormality indication detecting means, a coping method database, a coping method extracting means, a visual confirmation availability determining means, a priority setting means, and a coping method notifying means. The abnormality/abnormality indication detecting means detects an abnormality or an abnormality indication of equipment. The coping method database stores a coping method for the abnormality or the abnormality indication, the coping method including visual confirmation. The coping method extracting means extracts the coping method for the detected abnormality or the detected abnormality indication from the coping method database. The visual confirmation availability determining means determines whether the extracted coping method includes visual confirmation. When there is a plurality of extracted coping methods, the priority setting means sets a high priority to the coping method including visual confirmation. The coping method notifying means makes a notification of the coping method based on the set priority.
