Title:
BREAKDOWN PREDICTION DEVICE, BREAKDOWN PREDICTION METHOD, AND BREAKDOWN PREDICTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/090104
Kind Code:
A1
Abstract:
Provided is a breakdown prediction device which is provided with a vibration measurement unit for measuring vibrations generated from a monitored target apparatus and a signal processing unit for performing a breakdown prediction in the case where the vibration measurement unit measures specific vibrations, the maximum amplitude value of which exceeds an upper limit amplitude threshold value, and an amplitude value of which at the time when a specified period of time elapses from when the upper limit amplitude threshold value is exceeded falls below a lower limit amplitude threshold value.
