석유화학플랜트 내 밀폐공간 작업장의 IoT기술 기반 안전모니터링시스템 개발 = Development of a Safety Monitoring System based on IoT Technology for Confined Space Workplaces in Petrochemical Plants

국문 초록 (Abstract)

본 논문은 석유화학 플랜트에서의 밀폐공간 작업장의 IoT 기술 기반 안전모니링시스템의 설계 및 구현에 관한연구이다. 밀폐공간 작업 관련 질식 재해는 최근 10년간 감소하지 않고 지속적으로 발생하고 있으며, 총 196건의 사고발생에 따른 치명율은 47.4%로 나타났다. 특히 석유화학 플랜트는 반응기, 반응탑, 저장탱크, 화학물질이 포함된 폐수처리시설 등 밀폐공간 작업 시 많은 위험 요소를 포함하고 있어 효과적이고 안정적인 안전 작업 관리시스템의 도입이 요구되어진다. 따라서, 제안된 시스템은 IoT 센서, 유무선 복합 통신 네트워크, 이동형 CCTV 및 AI 영상분석 기술 등을활용하여 밀폐된 공간 내의 작업 조건을 모니터링하고 분석하고자 한다. 본 시스템은 밀폐공간 작업 시 유해 가스 감지, 작업자 위험 행동 등 이상 상황 발생 시 즉시 알람을 발령하고, 안전관리자 및 감독자가 신속히 대응할 수 있도록 지원한다. 본 연구에서 개발한 IoT 기반의 안전모니터링시스템은 석유화학 플랜트 현장을 대상으로 한 스마트 안전 기술 모델로서 재해 예방에 기여할 것으로 기대한다.

This paper presents the design and implementation of an IoT-based safety monitoring system for confined spaces in petrochemical plants. Confined space-related asphyxiation has persisted over the past decade, with a total of 196 incidents resulting in a fatality rate of 47.4%. Petrochemical plants in particular contain numerous hazards in confined spaces, including reactors, reaction towers, storage tanks, and chemical-laden wastewater treatment facilities, necessitating the introduction of an effective and reliable safety management system. The proposed system employs IoT sensors, a hybrid wired/wireless communications network, mobile CCTV, and AI video analysis technology to monitor and analyze working conditions within confined spaces. The system promptly issues alerts during abnormal situations such as the detection of hazardous gases or risky worker behavior, thereby helping safety managers and supervisors respond swiftly. The IoT-based safety monitoring system developed in this study is expected to contribute a smart safety technology model to use in petrochemical plant sites for disaster prevention.
