Title:
IMPROVED SOUND-BASED VESSEL CLEANER INSPECTION
Document Type and Number:
WIPO Patent Application WO2002060606
Kind Code:
A3
Abstract:
Sound detection techniques and sound discrimination techniques are used to analyze the real time sounds generated during the operation of cleaning heads (304) operating within a vessel (310) to determine if the cleaning heads are operating properly. During a typical cleaning operation pressurized cleaning solution is dispensed through a rotating nozzle assembly (106) inside the vessel. As the nozzles rotate the spray moves about the interior of the vessel creating a unique sound pattern. By placing one or more pickups (312) on the exterior of the vessel the sound is captured and fed to an analyzing device (424) for analysis. Key properties such as, but not limited to, sound pressure levels, amplitude variations, spectral content, and rotational information are extracted and analyzed against the reference parameters.
