故障予測装置及び故障予測方法ならびに故障予測プログラム
Document Type and Number:
Japanese Patent JP5712936
Kind Code:
B2
Abstract:
A breakdown prediction device of the present invention includes: a vibration measurement unit that measures vibrations generated from a device being monitored; and a signal processing unit that performs breakdown prediction when a specific vibration is measured at the vibration measurement unit, a maximum vibration amplitude value of the vibration exceeding an upper limit vibration amplitude threshold, and a vibration amplitude value thereof being below a lower limit vibration amplitude threshold at a point in time when a specified time is reached from a point in time when the vibration exceeds the upper limit vibration amplitude threshold.
