Title:
FAILURE PREDICTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/210353
Kind Code:
A1
Abstract:
Provided is a failure prediction system that outputs not only the condition of hydraulic oil but also failure prediction information about a device through real-time processing. This failure prediction system comprises: an oil condition sensor attached to a device; a parameter calculation unit that calculates values of a plurality of parameters indicating the condition of hydraulic oil on the basis of a sensor output from the oil condition sensor and correlation information between the sensor output and values of the plurality of parameters indicating the condition of the hydraulic oil; and a failure prediction determination unit that predicts a failure of the device on the basis of the values of the parameters, and that specifies and outputs a parameter presumed to be a cause of the predicted failure. The failure prediction system outputs not only the condition of the hydraulic oil but also failure prediction information about the device through real-time processing.
