Abstract

In order to maintain clean environment in an interior space and an enclosed cattle pen, we have to measure and control environmental factors which are temperature, humidity and CO2, CH4 and so on. Although the measured values are within the normal range, those are increased or decreased sharply by the feces or environmental impacts. In order to take early an appropriate action, we propose an early warning method(EWarM) in this paper, which can recognize the rapidly changing time for the increasing or decreasing rate of the measured values. In addition, we developed fuzzy control system based on an EWarM. We verified that this system based on an EWarM is used for eliminating that impacts through performance evaluation in a variety of environmental situations.

실내나 밀폐된 축사시설에서는 청정한 환경을 유지하기 위해 온도 습도 그리고 이산화탄소, 메탄가스 등과 같은 환경요인들을 측정하고 관리하여야 한다. 이때 측정된 수치가 관리대상 구간의 정상범위 내에 존재할지라도 시설이나 축적된 배설물과 주변 환경과의 상호작용 등으로 인한 예측치 못한 상황이 발생하면 측정수치는 급격하게 증가 또는 감소하게 된다. 본 논문에서는 이처럼 급격하게 증가하거나 감소하는 비정상 패턴의 변화가 발생할 경우, 이를 인식하여 위해 요소를 미리 제거할 수 있는 조기경고기법(EWarM)을 제안하였다. 그리고 이를 기반으로 한 퍼지 에이전트를 구현하였다. 다양한 상황에서의 성능평가를 통해 조기경고기법(EWarM)에 기반한 퍼지 에이전트가 위해 요소를 제거하는데 유용하다는 것이 입증되었다.
