POWER EQUIPMENT SOUND DIAGNOSIS SYSTEM

WIPO Patent Application WO/2016/027996

A1

The present invention relates to a power equipment sound diagnosis system. The purpose of the present invention is to provide a power equipment sound diagnosis system which can amplify sound generated by power equipment and analyze a sound signal of a filter bank allowing a sound signal of a specific frequency band to pass therethrough, to diagnose the power equipment in real-time, so as to rapidly and accurately determine whether the power equipment malfunctions, and to replace, in advance, accident equipment at a proper time through diagnosis prevention, thereby saving electric energy. The present invention for achieving the purpose comprises: a sound collection apparatus for amplifying sound generated by power equipment and converting a sound signal of a specific band from among amplified sound signals into a digital signal; and a diagnosis apparatus for segmenting the digital signal received from the sound collection apparatus into a plurality of parts in units of bits to have reference ranges for signals having passed through the filter bank unit of the sound collection apparatus, respectively, monitoring data values of the segmented parts, and diagnosing data through time-series or frequency-series analysis.
