FIELD: processes and apparatuses for detecting mechanical impulse type actions upon member of plant.
SUBSTANCE: noise of industrial troubles existing in member of plant is continuously detected by means of pickup placed in member of plant and it is converted to measured signal subjected to Fourier transform. On base of large number of spectra of absolute values detected by means of such procedure, evaluation function indicating occurrence of impulse mechanical action upon member of plant is formed. Apparatus for performing the method includes pickup placed on member of plant, analog-digital converter connected with pickup for converting measured signals from pickup to digitized ones and for supplying them to calculating device for performing calculation operations.
EFFECT: improved design of apparatus, enhanced efficiency of method.
