Abstract

A waveform detector having a signal processing function for producing an output waveform by detecting, by characterizing, a transient state variation having no periodic repetition or by subjecting an input waveform to 1 / f fluctuation conversion, and a state monitoring system utilizing the waveform detector. The waveform detector characterizing the characterization of the sign of state variation, chracterized in that a digital filter operating means of a processing section is provided with a plurality of digital filters, and means (phase matching parameter means) for altering the phase of any of, the elementary pattern of multiplication coefficient pattern defined by the coefficient pattern derived from a nonintegral-n-times integration expression, the input signal data, and the digital filter output is provided.

Description

field of invention [0001] The present invention relates to a waveform detection device and a state monitoring system using the same, wherein the waveform detection device has a signal processing function of characterizing and detecting a transition state without periodic repetition, or by performing 1 / f fluctuation transformation on an input waveform to obtain the output waveform. Background technique [0002] In condition monitoring systems, as a method of detecting signs from time-series data, along with the development of computers, there has been a method of adopting practical waveform reading technology. Compared with Fourier transform, waveform reading is inferior in spectrum analysis accuracy. However, compared with Fourier transform, waveform reading can perform dynamic analysis, and has the characteristic of being able to more accurately capture changes in the frequency spectrum of time-series data and images. For this reason, at present, waveform reading technolo...
