Abstract

Using virtual reality technology, users can learn and experience many interactions in virtual space like the actual physical space. This study was conducted to develop air flow simulator that allows farmers and consultants to consult air flow through VR devices by creating a greenhouse or pigpen model. It can help educate farmers about the importance of ventilation effects for agricultural facilities. We proposed CFD visualization system by building a virtual reality environment and constructing database of CFD and structure of agricultural facilities. After consultants can set up situations according to environmental conditions, the users experience the visualized air flow of agricultural facility according to the ventilation effects. Also it can provide a quantified environmental distribution in the agricultural facility. Currently, the CFD data in agricultural facilities are established during winter and summer. In order to experience various environmental conditions in the developed system, The experts need to run CFD data under various environmental conditions and register them in the system requirements.

4차산업혁명 기술인 가상현실 기술을 이용하면 현장에 가지 않고 가상공간에서 교육하고 체험하는 것이 가능하 여 사용자가 가상의 세계에서 현실과 같은 자연스러운 상호작용이 가능하다. 가상현실 기술을 활용하여 농업인 에게 시각적으로 인지하기 힘든 공기유동, 환기효과 등 의 체험을 하도록 하여 농업시설 관리의 중요성을 교육 하는데 기여할 수 있다. 본 연구는 농업시설인 온실이나 돈사 모델을 생성하고 환경조건에 따라 원격 서버에 저 장된 CFD 데이터를 불러와 농업인 및 컨설턴트가 VR 기기를 통해 공기유동을 보면서 컨설팅 할 수 있는 시 뮬레이터 시스템을 개발하기 위해 수행되었다. 농업시설 3차원 오브젝트 생성, 농업시설 가상현실 환경구축, CFD 및 농업시설 구조물의 데이터베이스 구축, CFD 가 시화 시스템에 대하여 제안하였다. 컨설턴트가 환경조건 에 따라 상황을 설정하여 사용자와의 상호작용에 의해 농업시설내의 공기유동 정보를 체험할 수 있다. 사용자 는 동절기나 하절기의 환기여부에 따라 가시화된 공기유 동을 체험할 수 있으며, 농업시설 내의 지점별 위치에 대한 정량화된 환경분포를 제공받을 수 있다. 현재 동절 기 및 하절기 주간 3연동 온실 및 2009 자돈 돈사에 대 한 데이터가 구축 되어 있으며, 향후 개발된 시스템에 다양한 환경조건에 대한 체험을 하도록 CFD 전문가 들 은 다양한 환경조건에 대한 CFD를 수행하여 시스템에 등록하는 것이 필요하다. 또한 농업시설 내 공기상태를 눈으로 보고 정확하게 파악하여 적정환기를 할 수 있도 록 농업인들에게 가상현실 기기조작을 교육할 수 있는 체계가 필요할 것으로 판단된다.
