Abstract

In this paper, we propose human detection and fuzzy temperature control system for energy reduction of cooling device in elevator. In order to improve problems of existing cooling device using the refrigerant, energy reduction and efficient management are continuously achieved because of operation of thermoelectric cooling device using the human detection and fuzzy temperature control system. The proposed system confirms the number of passengers in elevator and temperature is then controlled by those numbers and an average temperature for the season in fuzzy system. The human detection method scans the number of passengers using a head part as a feature based on bird's-eye view camera in elevator. The fuzzy system determines elevator internal temperature considering atmospheric temperature and the scanned passenger numbers as a look-up table. The proposed system reduces energy of the cooling device through the human detection and temperature control. In experiment, energy reduction is confirmed and the performance of the proposed system is verified.

본 논문에서는 승강기용 냉각장치의 에너지 절감을 위한 사람 검출과 퍼지 온도 제어 시스템을 제안한다. 기존의 냉매를 사용하는 냉각장치의 문제점들을 개선하기 위해 사람 검출과 퍼지 온도 제어 시스템으로 열전냉각장치를 구동시켜 에너지 절감을 하고 자동적으로 효율적인 온도 관리를 한다. 제안된 시스템은 사람 검출을 통해 승강기 탑승 인원수를 확인하고 나서 퍼지 시스템에서 탑승 인원수와 계절 평균 기온을 기반으로 온도 제어를 한다. 사람 검출 방법은 승강기에서 조감도 카메라를 기반으로 사람의 머리 부분을 특징으로 사용하여 탑승 인원수를 검지한다. 퍼지 시스템은 look-up table 방법으로서 검지된 인원수와 기온을 고려하여 승강기의 내부 온도를 결정한다. 제안된 시스템은 사람 검출과 온도 제어를 통해 냉각장치의 에너지를 절감시킨다. 실험을 통해 에너지 절감을 확인하고 제안된 시스템의 성능을 검증한다.
