Abstract

Disaster accidents at industrial sites have been increasing every year. In shipyards there are countless enclosed spaces causing issues like harmful-toxic gases stuck in those sealed areas. And due to such special and complicated structures of the working places with many layers of walls separating each other, there exist more issues of communication with workers trapped inside when accidents happen. Under this circumstance there must be a huge difficulty to evacuate or rescue the workers in case of any disaster. Therefore, in this paper, We would like to introduce the "integrated safety system" to more effectively deal with the problems and prevent such disasters in tough working environments. The suggested integrated safety system can prevent accidents in advance because it can control the data on the location of the workers in real time and the numerical values such as gas, oxygen, and carbon dioxide generated in the workplace in real time.

최근 들어 산업현장에서의 재난 사고는 해마다 증가하고 있는 추세이다. 조선업의 경우 밀폐된 공간이 많기 때문에 작업시 발생하는 각종 유해가스에 대한 이슈와 작업장 구조가 복잡하기 때문에 사고가 발생하였을 경우 격벽으로 인한 통신, 사용자 위치추적의 어려움 등에 대한 문제점이 제기된다. 이러한 상황에서 여러 가지 재해나 재난이 발생할 경우 작업자의 피난이나 구조에 있어 상당한 어려움이 발생한다. 이에 본 논문에서는 밀폐된 공간에서 각종 재해나 재난이 발생할 경우 사고를 사전에 방지하기 위한 통합안전시스템을 제안한다. 제안하는 통합안전시스템은 작업자들에 대한 위치정보의 데이터를 실시간 관리하고 작업장에서 발생하는 가스, 산소, 이산화탄소 등의 수치도 실시간으로 관리가 가능하기 때문에 사고를 미연에 방지할 수 있다.
