Abstract

The most important part of the smart livestock building system is to maintain a breeding environment so that livestock can grow to high quality despite changes in the internal and external atmospheric environment. Especially, it is very important to maintain the temperature and humidity in the livestock building because various diseases occur during the summer and winter. To manage the environment suitable for livestock, a smartfarm system for livestock building is applied, but it is very expensive. In this study, we propose a hardware design and control method for low cost system based on HMI and fuzzy control. To evaluate the performance of the proposed system, we did a simulation experiment in the atmospheric conditions of summer and winter. As a result, it showed the performance of minimizing the temperature and humidity stress of livestock. And when applied to the livestock building, the proposed system showed stable control performance even in the change of the external atmospheric environment. Therefore, as with these results, if proposed system in this study is applied to the smart farm system, it will be effective in managing the environment of livestock building.

스마트 축사 시스템에서 가장 중요한 부분은 내·외부 대기환경 변화에도 가축이 고품질로 성장할 수 있도록 사육환경을 유지하는 것이다. 특히 여름과 겨울에는 여러 질병이 발생하기 때문에 축사환경에서 온·습도 유지가 매우 중요하다. 이러한 환경을 관리하기 위해 축사용 스마트 시스템이 도입되고 있으나 매우 고가이다. 본 연구에서는 퍼지제어와 HMI를 기반한 저가의 시스템 설계와 제어 방법을 제안한다. 제안된 시스템의 성능을 평가하기 위해 여름철과 겨울철의 대기환경 조건을 주어 시뮬레이션 실험하였으며, 그 결과 가축이 받은 온습도 스트레스를 최소화하는 성능을 보였다. 그리고 실제의 축사에 적용했을 때도 제안된 시스템은 외부대기 환경변화에도 안정적인 제어성능을 보였다. 본 연구에서 제안한 기법이 스마트팜 제어기로 적용된다면, 축사 환경관리에 있어 효과적일 것이다.
