Abstract

According to the Ministry of Employment and Labor's statistics on occupational fatalities in South Korea, more than half of the fatalities in the past five years have occurred in the construction industry. The stuck-by and caught-in-between accidents associated with construction equipment is the major source of fatalities from construction sites. In order to prevent such accidents in construction sites, the government has spent lots of efforts including proposing the "special law on construction safety" and encouraging the implementation of new technology for accident prevention. However, numerous accidents are still occurred at construction sites and further efforts are still required. In this manner, this study developed a collision prevention technique that can prevent collision between equipment and worker by recognizing location and type of the nearby objects through ultrasound scanning. The study conducted a pilot experiment and the analysis results demonstrate the feasibility of achieving high performance in both object recognition and location estimation. The developed technique will contribute to prevent collision accidents at construction sites and provide the supplemental knowledge on developing automated collision prevention system for construction equipment.

고용노동부의 2020년 산업재해 사고 사망 통계 발표에 따르면 최근 5년간 발생한 업무상 사고 사망 재해의 절반 이상이 건설업에서 발생하고 있다. 그중 건설기계와 관련된 충돌 및 협착 사고가 사망 재해의 큰 부분을 차지하고 있다는 것을 알 수 있다. 정부는 건설 현장에서 발생하는 사고를 예방하기 위해 "건설안전특별법" 발의, 사고 예방을 위한 새로운 기술의 도입 장려 등 큰 노력을 기울이고 있지만, 여전히 건설 현장에서 수많은 안전사고가 발생하고 있다. 이에 본 연구는 초음파 스캐닝 기술을 통해 반경 내 대상의 종류와 위치를 인식하여 건설기계와 작업자 간의 충돌사고를 예방할 수 있는 기술을 개발했다. 본 연구는 파일럿 실험을 수행하였으며, 결과 분석을 통해 대상 인식과 위치 추정 모두에서 높은 정확도로 기술의 실현 가능성을 증명하였다. 개발한 기술은 건설 현장에서 발생하는 충돌사고를 예방하고, 자동화된 건설기계 충돌사고 예방 기술 개발에 이바지할 수 있을 것으로 기대된다.
