The invention relates to a system (1) for monitoring, operating and maintaining an industrial plant (2), in particular in the metal-producing industry or the steel industry, including: at least one mobile terminal device (3) with at least one sensor (4) for recording measured values within the industrial plant (2), at least one position sensor (5) for detecting the position of the at least one mobile terminal device (3) in the industrial plant (2), a central data processing device (6) for processing the measured values recorded by the at least one mobile terminal device (3) by means of the at least one sensor (4), taking into account the position of the at least one mobile terminal device (3) recorded by means of the at least one position sensor (5) in the industrial plant (2), and at least one communication network (7) for exchanging data between the at least one mobile terminal device (3), the at least one position sensor (5) and/or the central data processing device (6).

The invention also relates to a method for monitoring, operating and maintaining an industrial plant (2), in particular in the metal-producing industry or the steel industry.

A device includes a catalog storage unit that stores a catalog having versatility; a catalog control unit that specifies the catalog corresponding to a target machine tool to be subjected to state determination based on machine tool information including an item of facility type and acquires the catalog from the catalog storage unit; a feature quantity extraction unit that extracts a feature quantity from sensor data detected from the target machine tool; a sensor data processing unit that performs state determination of the target machine tool based on the feature quantity distribution included in the acquired catalog and the feature quantity extracted from the sensor data; a feature quantity tuning unit that performs tuning of the feature quantity distribution by mapping the extracted feature quantity to the feature quantity distribution; and a catalog updating unit that updates the catalog based on the feature quantity distribution after tuning.
