Abstract

This paper introduces a sensor system based on indoor locations in order to implement the Building Energy Management System. This system consists of a thermopile sensor and an ultrasonic sensor. The sensor module is rotated by $360^{\circ}$ and yawed up-and-down by two electric motors. Therefore, it can simultaneously detect the number and location of the inhabitants in the room. It uses wireless technology to communicate with the building manager or the smart-home server, and it can save electric energy by controlling the lighting system or heating/air conditioning equipment automatically. We also demonstrate the usefulness of the proposed system by applying it to a real environment.

본 논문에서는 Building Energy Management System(BEMS) 구현을 위해 "재실자의 위치 및 인원정보" 에 기반을 둔 실내 위치 기반 서비스 및 그를 위한 센서 시스템에 대하여 제안한다. 본 논문에서 제안한 센서 시스템에는 열에너지 그 자체를 감지 할 수 있는 서모파일 센서와 비 접촉 방식으로 대상까지의 거리를 얻어낼 수 있는 초음파센서, 그리고 이를 제어하고 구동할 수 있는 기구 및 동작부가 포함된다. 본 시스템은 적절한 크기의 방 전체를 감시할 수 있도록, $360^{\circ}$ 회전과 틸팅이 가능한 구조로 되어있어, 실내공간내의 재실자의 인원 및 위치를 동시에 파악할 수 있다. 또한 무선통신 기술인 블루투스 모듈을 통해 빌딩 관리자나 스마트 홈 서버와의 통신이 가능하도록 되어 있어, 빌딩내의 조명이나 공조시스템을 자동으로 제어, 관리하게 함으로써 전체 에너지 절약을 가능케 한다. 마지막으로 측정 데이터 검증을 위한 실환경 실험을 통해, 본 연구에서 제안한 시스템의 효용성 및 타당성을 확인한다.
