Abstract

This study developed an application that automatically aggregates the number of loading and dumping events by using the work sound generated during mine haulage operations. To this end, the work sound was collected by riding directly on the loading and dumping work truck at Daesung MDI Danyang Office located in Danyang-gun, Chungcheongbuk-do. The singularity of the work sound of loading and dumping operations was analyzed. In order to aggregate the number of loading and dumping operations, each singularity was quantified and the classification criteria were divided. The developed work sound classification application starts to recognize the surrounding noise when the tablet PC receives the Bluetooth beacon signal, and the number of times is automatically counted when the loading and dumping operation sound is recognized according to the previously classified criteria. As a result of the field experiment, the count of the number of times was 100% successful, and the unit time required for truck work could be accurately measured.

본 연구에서는 적재 및 투하 작업 시 발생하는 작업음을 인식해 적재 및 투하 작업 횟수를 자동으로 집계해 주는 애플리케이션을 개발하였다. 이를 위해 충북 단양군에 위치한 대성 엠디아이 단양사업소에서 광석 운반 트럭의 적재 및 투하 작업음을 수집하였다. 적재 및 투하 작업 횟수 집계를 자동화하기 위해 작업음의 특이점을 분석하였고, 특이점을 기준으로 분류 기준을 수립하였다. 개발된 작업음 분류 애플리케이션은 태블릿PC가 블루투스 비콘 신호를 수신받으면 주변 소음을 인식하기 시작하며, 기존에 분류된 기준에 맞게 적재 및 투하 작업음이 인식되면 자동으로 횟수가 집계하였다. 현장 실험 결과, 횟수 집계는 100% 성공했고 트럭 작업의 단위 소요 시간도 정확하게 측정할 수 있었다.
