Abstract

In this paper, we propose indoor IoT monitoring system based on visible light communication using smart phone with attracting attentions in recent wireless communication. The main features and contributions of the proposed system developed in this paper are as follows. First, the actual data generated within indoor can be processed via the server by using only the visible light communication. Second, the collected data by using the visible light communication can be monitered by smart phone. Performance evaluation of the proposed system is performed under illumination of the normal fluorescent lamps. We first check successful transmission between transmitting module and receiving module of the data collection system. The monitoring system is tested according to the change of the degree of condensing and distance of the LED and the decoding success rate of the proposed smart phone application. We expect that the proposed system can be applied for indoor and outdoor IoT areas together.

본 논문에서는 최근 무선통신분야에서 주목 받고 있는 가시광통신과 IoT(Internet of Things) 시스템을 융합한 실내 IoT 모니터링 시스템을 제안한다. 제안 개발된 시스템의 주요한 특징과 기여도는 다음과 같다. 첫째, 실내에서 발생하는 실제 데이터를 가시광 통신만을 사용하여 오직 서버를 통하여 가공 처리 할 수 있다. 둘째, 가시광 통신을 이용하여 스마트폰으로 수집된 데이터를 모니터링 한다. 성능평가는 보통의 형광등이 비추는 곳에서 실험을 하였다. 먼저 데이터 수집 시스템의 송신 및 수신모듈간의 전송성공여부를 확인 한다. 모니터링 시스템은 LED의 집광 정도와 거리를 변화시켜 전송여부를 실험하고 제안된 스마트폰 어플리케이션의 디코딩 성공률을 실험 하였다. 본 논문에서 제안한 시스템은 실내뿐만 아니라 실외 IoT 분야에도 응용 적용 될 것으로 기대한다.
