Abstract

The mobile house of this article is provided with stand-alone power system that uses photovoltaic energy and enables sensing and environmental monitoring. Excess power generated is stored in lithium batteries, which enable smooth operation of the mobile house even in environment in which solar energy cannot be used. The house has been designed that its systems can be operated continuously by diesel power generation even when photovoltaic energy cannot be generated due to long rainy season or heavy snow. BMS (batter management system) has been constructed for photovoltaic and power management, and monitors the charge/discharge and usage amount of photovoltaic energy. Various sensing data are recorded and transmitted automatically, and the design allows for wireless monitoring by means of computer and smartphone app. The container house proposed in this study enables efficient energy management by performing optimal energy operation in remote areas, parks, event venues, and construction sites where there is no system power source.

본 논문은 태양광을 이용하여 에너지를 발전하여 생성되는 전력으로 각종 센서 및 환경 모니터링이 가능하도록 계통 독립형 전력을 공급한다. 생산된 잉여 전력은 리튬 배터리에 저장시켜 태양광이 없는 환경에서도 컨테이너 하우스가 원활한 구동이 가능하도록 설계하였다. 긴 장마나 폭설로 인하여 태양광 생성이 어려우면 디젤발전으로 시스템이 멈추지 않고 구동할 수 있도록 하였다. 태양광 및 전력 관리를 위해 BMS(Battery Management System)를 구축하여 태양광 방/충전 및 사용량을 모니터링한다. 각종 센싱 데이터를 자동으로 기록하고 전송되며, 컴퓨터 및 스마트폰 앱을 통해 무선 모니터링이 가능하도록 설계하였다. 본 연구에서 제안하는 컨테이너 하우스는 계통 전원이 없는 오지, 공원, 행사장, 공사현장 등에서 최적의 에너지 운영을 수행함으로써 효율적인 에너지 관리가 가능하다.
