METHOD AND DEVICE FOR DETECTING PLACE OF PULSED MECHANICAL EFFECT OF EQUIPMENT COMPONENT Russian patent published in 2010 - IPC G01H1/00 

FIELD: physics.

SUBSTANCE: in the method and device for detecting the place of pulsed mechanical effect on an equipment component (2) operation noise in that component (2) is continuously detected using several sensors (4_s) fitted on the component (2), in which the operation noise is converted to a measurement signal (M), subject to conversion in first time windows (Δt₁). Based on the obtained first transformants, a first evaluation function (K_1,s) is output, which indicates absence of pulsed mechanical effect on the equipment component (2). According to the invention, when detecting effect in second shorter time windows (Δt₂) using the same algorithms, second transformants and second evaluation functions (K_2,s) are output respectively, on the basis of which the time moment (t₅) in which the sound signal generated as a result of the effect reaches the sensor (4_S) is determined. The effect is accurately determined based on the difference in delay times of sensors (4_S).

EFFECT: more accurate determination of the place of effect.
