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

摘要

The invention relates to a method and device for detecting the position of 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 plurality of sensors (4_s) which are arranged on the plant component (2) and converted by the above into a measured signal (M_s), said measured signals of the sensors undergoing a transformation in a first time window (?t₁). A first evaluation function (K_1,s) is derived from a plurality of first transformations determined in said manner, said evaluation functions displaying the appearance of the pulsed mechanical effect on a plant component (2). According to the invention, when detecting an effect following the second shorter time window (?t₂) having the same algorithms, second transformed and respectively, second evaluation functions (K_2,s) are derived, from which, respectively, one time point (t_s) is determined, wherein the sound signal produced by the effect impacts upon the sensor (4_s). From there, running time differences produced between the sensors (4_s) can be exactly reconstructed on the position of the effect.
