Abstract

It is essential for vertical smart farms that artificially grow crops in an enclosed space to properly utilize air environment facilities to create an appropriate growth environment. However, domestic vertical smart farm companies are creating a growing environment by relying on empirical data rather than systematic methods. Using IoT to create a growing environment based on systematic and precise monitoring can increase crop production yield and maximize profitability. This study aims to construct a monitoring system using IoT and to analyze the cause by demonstrating the imbalance of temperature environment, which is a significant factor in crop cultivation. 1) The horizontal temperature distribution of the multi-layer shelf was measured with different operating methods of LED and air conditioner. As a result, there was a temperature difference of "up to 1.7℃" between the sensors. 2) As a result of measuring the vertical temperature distribution, the temperature difference was "up to 6.3℃". In order to reduce this temperature gap, a strategy for proper arrangement and operation of air conditioning equipment is required.

밀폐된 공간에서 인공적인 방법으로 작물을 재배하는 수직형 스마트 팜은 공기 환경 설비를 적절히 활용하여 적정한 생육환경을 조성하는 것이 중요하다. 하지만 국내 수직형 스마트 팜 기업들은 체계적인 방법이 아닌 경험적 데이터에 의존하여 생육환경을 조성하고 있다. IoT를 활용하여 체계적이고 정밀한 모니터링을 토대로 생육환경을 조성한다면 작물의 생산 수율을 높이고 수익성을 극대화할 수 있다. 본 연구의 목적은 IoT를 활용하여 모니터링 시스템을 구성하고, 작물 재배에 주요한 요인인 온도 환경의 불균형을 실증하여 그 원인을 분석하는 데 있다. LED와 냉방기의 가동 방식을 달리하며 1) 다층 선반의 수평 온도 분포를 측정한 결과 센서 간에 "최대 1.7℃"의 온도 격차를 보였다. 2) 수직 온도 분포를 측정한 결과 "최대 6.3℃"의 온도 차이를 보였다. 이러한 온도 격차를 줄이기 위해서는 공조설비의 적절한 배치와 운영 방식에 대한 전략이 필요하다.
