DEVICE TO DETERMINE DETONATION Russian patent published in 2011 - IPC G01L23/22 G01M15/12 F02P5/152

Abstract RU 2431816 C1

FIELD: transport.

SUBSTANCE: output signal of device detonation pickup 28 is filtered by multiple of band filters 36-39 to extract components of multiple frequency bands oscillation (f1-f4). Weight factor G1-G4 multiplying component of frequency band oscillation in each frequency band is set so that said factor increase with increase in frequency band noise intensity. Thus, component of frequency band oscillation in each frequency band is synthesized by weighing in compliance with effects of noise intensity in every frequency band.

EFFECT: decreased noise, higher accuracy of detonation determination.
