Abstract

In this paper, we propose an autonomous Indoor lighting control system in which indoor lighting devices are autonomously controlled such that electricity bills are minimized in our daily life. Our focus is to utilize Passive Infrared (PIR) sensors to detect the presence of human being indoor and automatically to control indoor lighting electric devices. A control algorithm is also devised to control the whole system. We justify the proposed system by demonstrating specific applications in our everyday life. Cost survey and experimental results also demonstrate the efficiency of the proposed system in real life.

본 논문에서는 실내 전력소모를 효율적으로 줄이기 위하여, 무선센서네트워크 기반의 자율 실내조명 제어 시스템을 제안한다. 제안된 시스템에서는 먼저 출입문에 부착된 수동 적외선 (Passive Infrared: PIR) 센서를 이용하여 각 출입문을 통해 실내로 들어오고 나아가는 사람 수를 감지하다. 각 출입문에서 측정된 센서 값들은 무선센서네트워크를 통해 중앙 제어장치로 전송된다. 중앙제어장치는 전송된 센서 값을 이용하여 실내에 사람의 존재 유무를 파악할 수 있는 제어 알고리즘을 통해 실내조명을 자율적으로 제어 한다. 비용분석 및 시뮬레이션을 통해 제안된 시스템이 일상생활에 적용될 경우 약 20%의 전기소모를 절약할 수 있음을 보였다.
