Abstract

Provided is a machine state detecting device capable of easily detecting the state of a machine, regardless of whether an unknown operation that is not expected to cause damage is performed. A state detecting device 100 includes a collection device 1a that collects, at a plurality of times, state information if indicating the state of the machine that changes chronologically, and an arithmetic processing device 1b that processes a plurality of pieces of the state information if collected at the plurality of times to detect the state of the machine. The arithmetic processing device 1b includes: a classification process section 1i that classifies a feature amount vector having the type of the state information if as a feature amount into any of a plurality of clusters, and provides a classification ID; a detection process section 1j that detects a damage the machine received, based on state information 1g indicating the state of the machine that changes chronologically; and a tying process section 1l that ties an interval in which the damage was detected by the detection process section 1j to the classification ID provided in the interval by the classification process section 1i.

A machine state detecting device comprising a collection device that collects, at a plurality of times, state information indicating a state of a machine that changes chronologically, and an arithmetic processing device that detects the state of the machine by processing a plurality of pieces of the state information collected at the plurality of times,

wherein the arithmetic processing device comprises:
a classification process section that identifies a plurality of feature amount vectors having a type of the state information as a feature amount by temporally dividing the plurality of pieces of the state information collected by the collection device, classifies the identified feature amount vectors into any of a plurality of prescribed sets, and, to the feature amount vectors that have been classified, provides a classification ID identifying the set to which each feature amount vector belongs;
a detection process section that detects a damage received by the machine based on the state information, collected by the collection device, indicating the state of the machine that chronologically changes;
and
a tying process section that ties an interval in which the damage was detected by the detection process section to the classification ID provided in the interval by the classification process section.
