콘텐츠 소개

본 연구에서는, 오디오 신호 처리와 인공 신경망 기법을 통합하여 너트을 분류하고 등급을 매기는 방법이 도입되었다. 너트가 철판 디스크의 충돌로 인해 생성된 소리가 철판 디스크아래에 놓인 마이크에 의해 받아들여져 사운드 카드를 통해 PC로 전달되는 시스템이 설계되고 개발되었다. 또한, MATLAB 소프트웨어 프로그램에 의해 저장되고 처리되었다. 압전 센서와 회로는 추가적인 주변 소음을 제거하기 위해 사용되었다. 데이터의 시간 영역과 파장 영역 특징은 MATLAB 소프트웨어를 사용해 추출하고 인공신경망 툴박스를 이용해 분석했다.
