Failure prediction system, failure prediction device, and failure prediction method

Abstract

In order to provide a mechanism which predicts a risk of future failure occurrence, by using fiber optic sensing, this failure prediction system comprises: a sensing function unit which acquires the environmental information detected by the optical fiber; an event classification function unit which classifies, by type, events occurring at each position of the object indicated by the environmental information, on the basis of event classification conditions; and a failure occurrence risk calculation unit having, in advance, one or more failure models obtained by modeling a physical mechanism that leads to a malfunction in the object, wherein the failure occurrence risk calculation unit calculates a failure occurrence risk in each object by the mechanism, and outputs the accumulated result as a risk or availability.
