METHOD AND DEVICE FOR DETECTING A PULSED MECHANICAL EFFECT ON A PLANT COMPONENT

摘要

The invention relates to a method and device for detecting a pulsed mechanical effect on a plant component (2), whereby an operating noise in the plant component (2) is continuously recorded by means of a sensor (4) which is arranged on the plant component (2) and converted by the above into a measured signal (M) which is subjected to a mathematical transformation. According to the invention, a sliding mean is calculated by determining the quantiles from the determined transformations and the evaluation function (K(t)), which displays the application of a pulsed mechanical effect on the plant component (2), is derived from said sliding mean.
