Abstract

According to the Korea Occupational Safety and Health Agency's (KOSHA) report on industrial accident statistics over the past four years, the number of casualties at construction sites from 2017 to June 2020 was about 93,158 and the number of deaths was about 1,977, showing a high trend of safety accidents among the eight major occupational groups, with the construction industry ranking third in total and the death rate being the highest in total. Among them, the number of deaths caused by falls in the entire occupational category is about 1,267, the highest rate of deaths due to contact is about 522, which is a frequent safety accident among the top three accident types. This paper aims to help reduce the overall proportion of construction safety accidents by developing smart safety sensing devices using ultrasonic sensors to prevent two types of safety accidents, which have the highest rate of occurrence among various types of safety accidents occurring at construction sites.

한국산업안전보건공단의 산업재해통계 보고서 최근 4년 동안의 자료를 확인하면 2017년부터 2020년 6월까지 건설현장의 재해자 수가 약 93,158명, 사망자 수가 약 1,977명으로 건설업이 재해율 총 3위, 사망률 총 1위로 높은 안전사고 추이를 보이고 있다. 그 중에서도 전체 직업군에서 추락으로 인한 사망사고 및 접촉으로 인한 사망사고는 전체 사고 유형 중 3위 안으로 빈번하게 발생하는 안전사고이다. 본 논문은 건설현장의 다양한 유형의 안전사고 중 발생 비율이 가장 높은 추락과 접촉 사고 두 유형의 안전사고를 예방하기 위해 초음파 센서를 이용한 스마트 감지 장치를 개발하여 직접 현장 작업자가 경험하게 한 결과, 설문참여 작업자의 69.5%이상이 센서의 현장 적용성에 대해 긍정적으로 평가하였으며, 이를 토대로 건설업 안전사고의 전체 비율을 감소하는데 일조 하고자 한다.
