초록

전기화재의 원인중의 하나는 직렬 아크이다. 최근까지 아크 신호를 검출하기 위해 다양한 기법들이 진행되고 있다. 시간 신호에 푸리에 변환, 웨이블릿 변환, 또는 통계적 특징 등을 활용하여 아크 검출을 하는 방법들이 소개되었지만, 변환 및 특징 추출은 부가적인 처리 시간이 요구되는 단점이 있다. 반면에 최근의 딥러닝 모델은 종단간 학습으로 특징 추출 과정없이 직접 원시 데이터를 활용한다. 그러나, 딥러닝의 문제는 연산 복잡도가 높다는 것이다. 이 문제는 단말기에 딥러닝 연산 모듈을 넣기가 어렵게 한다. 따라서 본 논문에서는 복잡도가 상대적으로 낮은 기계학습 기법중에 로지스틱회기 (logistic regression)를 이용하여 아크 검출을 하는 기법을 제안한다.

The arc is one of factors causing electrical fires. Over past decades, various researches have been carried out to detect arc occurrences. Even though frequency analysis, wavelet and statistical features have been used, arc detection performance is degraded due to diverse arc waveforms. On the contray, Deep neural network (DNN) direcly utilizes raw data without feature extraction, based on end-to-end learning. However, a disadvantage of the DNN is processing complexity, posing the difficulty of being migrated into a termnial device. To solve this, this paper proposes an arc detection method using a logistic regression that is one of simple machine learning methods.
