Title:
VIBRATION ANALYSER, AND MACHINE COMPONENT DIAGNOSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/173631
Kind Code:
A1
Abstract:
This vibration analyser is operated on the basis of a signal received from an information terminal, is capable of transmitting a signal obtained as a result of being operated to the information terminal, and analyses the vibration of a machine component. The vibration analyser is provided with: a vibration sensor which detects the vibration of the machine component; a filter processing unit which extracts a prescribed frequency band from the waveform of a signal detected by the vibration sensor; and a calculation processing unit which performs frequency analysis on the waveform which has been subjected to filter processing and which is obtained by the filter processing unit, and obtains spectral data. Accordingly, the amount of data transferred between the vibration analyser and the information terminal can be reduced, and the data transfer time can be shortened.
