Acoustic-resonance method for control of the location of hidden hollow objects

Abstract

© Published under licence by IOP Publishing Ltd. There are quite a number of methods for monitoring the location of buried pipelines: radio wave method, radiation method, acoustic location, resonant-acoustic profiling, infrared thermography, electromagnetic method. However, these methods have several disadvantages: they are not applicable to pipelines of non-metallic materials, and also have a weak selectivity in controlling the location of buried pipelines when many different communications pass in close proximity to the object under control. In this work, an improved acoustic-resonance method for controlling the location of hidden hollow objects has been developed and implemented as an information-measuring complex consisting of devices for exciting and receiving forced vibrations. The algorithmic and software-technical support of the processes of controlling the information-measuring complex and processing of vibroacoustic signals in the LabVIEW environment has been developed and created.
