A soft and hardware complex for recording and processing of acoustic emission signals and for location and identification of their sources

Abstract

A soft and hardware complex designed for recording and processing acoustic emission (AE) signals in real time is described. The hardware part of the complex includes a computer with PCI connectors, four-channel parallel-reading analog-to-digital converters (ADCs), preamplifiers, and receiving converters. The software part of the complex is used to record and save in all recording channels the full shape of signals with a preset sampling frequency of up to 20 MHz, locate, identify, and classify AE sources in real time. It differs from analogs in the capability of saving the full shape of AE signals for further analysis and processing, in use of commercially produced ADCs, and in real-time data processing and classifying of AE sources.
