우리나라 농업은 농가 경영 여건이 열악하고, 농산물 수입 확대 등 불확실성 확대로 어려움에 처해 있다. 생산성 향상 등 경쟁력 강화가 강력히 요구된다. 정부와 민간 모두 농업 경쟁력 강화를 위해 스마트팜 보급에 나서고 있다. 본고에서 제시한 클라우드 기반 스마트팜 서비스는 스마트팜 운영에 필요한 각종 기기를 클라우드 상에서 운영하는 방식이다. Stand-Alone방식 스마트팜에서는 온실별로 설치하는 센서, 제어기, 운영PC 등 각종 장치들을 가상화하여 서비스의 형태로 제공하는 기술이다. 클라우드 기반 스마트팜 서비스는 사용자 관점에서 필요한 기능만을 서비스의 형태로 적용하기 때문에 도입비를 획기적으로 낮출 수 있고, 설치 및 관리가 용이하다.

The smartfarm is a leader in the Field of environmental monitoring in agriculture. By the use of wireless remote systems, monitoring applications of the smartfarm are able to provide vital information to the farmer wherever he may be. Absentee farmers are finding the ease of viewing the application graphs on their mobile phone is providing them with peace of mind. We design system and technical requirements of service for managing and operating smart-farm based on cloud technology. It describes requirements of cloud technology for monitoring, controlling, managing, and operating cloud-based smart farm. Smart farm system and service with cloud platform contains 3 interfaces and 3 services. In addition, smart-farm using cloud platform could have several cases so it should be established and managed in varying way depending on cultivars, its size and type. This paper will focus the industry's attention on the importance of Open/Standard Cloud platform thereby stimulating the smartfarm in agriculture.

Under the influence of the Fourth Industrial Revolution, there are many tries to promote productivity enhancement and competitiveness by adapting smart farm technology that converges ICT technologies in agriculture. This smart farming technology is emerging as a new paradigm for future growth in agriculture. The development of real-time cultivation environment monitoring and automatic control system is needed to implement smart farm. Furthermore, the development of intelligent system that manages cultivation environment using monitoring data of the growth of crops is required. In this paper, a fast and efficient development method for implementing a cloud-based smart farm management system using a highly compatible and scalable web platform is proposed. It was verified that the proposed method using the web platform is effective and stable system implementation through the operation of the actual implementation system.

Modern agriculture is changing from resource-oriented agriculture to technology-oriented agriculture. Agriculture, which combines science and technology, is recognized as a new growth engine, and governments, local governments, research institutes, and industry are working together to develop and disseminate various devices necessary for smart farms to build intelligent smart farms. Recently, research is being conducted to build a more intelligent agricultural environment by building a cloud platform. In this paper, we propose a plan to build an urban energy - independent smart farm that can utilize leisure time and agricultural activities by utilizing the rooftop of a city. Also, by using IT technology, various data of smart farm can be managed on remote server, and HMI module for controlling internal environment of smart farm can be developed to manage smart farm automatically or semi-automatically. The service model suggests a model that can manage the internal environment of the smart farm based on mobile.

전북지역의 130여개 스마트온실 중에서 주요한 10여개의 주요 온실에 대한 온습도, 이산화탄소, 광센서 및 기타 센서의 사용실태에 대한 조사를 수해하였다(2016년 9월~12월). 온실의 선정은 온실의 종류(비닐/유리)와 복합제어기 종류(국산/외산)를 중심으로 조사하였다. 국내외 업체의 장단점, 스마트기기의 활용과 문제점, 클라우드 기반의 3세대 한국형 스마트온실의 적용기반에 대한 조사를 수행하였다. 융복합 제어기와 센서는 자체의 신뢰성 이외에 운용상의 알고리즘 차이에서 오는 문제로 인해 농가에서 측정결과에 대한 신뢰성이 낮고, 측정이 부정확하고 일일측정 데이터에 대한 활용이 어렵고, 설정 값을 사용자가 직접 계산하고 값들을 입력해주어야 한다는 단점에 대한 의견이 대부분이다. 외국 제품은 데이터 측정값의 활용이 용이하고 복합 환경 상황에 알맞게 자동 계산 시스템이 체계적으로 작동하여 제어에 반영되며 국내 업체 설정 값의 범위보다 세밀하게 설정이 가능하다는 장점이 있으나 설치비용이 국내대비 3~4배 높고 고장 시 A/S가 느린 편이며 영어로 구성된 복잡한 시스템이기 때문에 100% 활용하기 어렵다는 단점이 있다. 스마트기기 활용은 복합 환경제어를 하는 농가이면 국내 업체와 외국 업체 모두 활용하고 있으며 주로 스마트 폰으로 사용되고 전용 어플이 아닌 PC원격 제어 소프트웨어인 팀뷰어(Teamviewer)를 이용하여 복합제어기 PC를 직접 조작하여 사용한다. 클라우드 활용으로는 복합환경제어기 회사에서 작물별 제어 방법과 데이터 정보를 제공하지 않는 점에 대한 농가의 불편함이 많은 편으로 작물별 농사방법이 많고 지역별 농사방법이 다르기 때문에 조사한 전북지역의 농가 10곳 모두 클라우드를 사용하지 않는 것으로 조사되었다. 다양한 온실 및 생육환경에 따른 표준화된 운영의 문제점을 개선하여 스마트팜에서 중요한 역할을 수행하는 복합센서의 표준시험방법과 절차를 개발하여 관련산업의 발전에 응용할 필요성이 있으며 단순한 하드웨어의 표준화 또는 개선방향보다는 농가의경험과 누적된 토양,작물 등의 재배 생육정보를 이용한 작물생육모델과 온실모델의 일치를 통해 센서-생육환경예측-검증방법의 포준화가 필요한 것으로 사료된다.

IoT, Big-data, AI, and Cloud technologies, which are core technologies of the 4th Industrial Revolution, have recently been applied to various fields and are being used as core technologies for new growth engines. Accordingly, these core technologies are applied to the agricultural field without exception, contributing to solving the problem of labor shortage, reducing production costs, and reducing environmental burden through remote and automated production without time and space constraints. However, as these core technologies are utilized, security incidents are occurring in the agricultural field as well. Accordingly, this study divides smart farms into three stages(Basic, Middle, and High) and presents the characteristics and security threats of each stage. In particular, as the number of container-based services and research increases under cloud platforms, we would like to suggest countermeasures focusing on security threats.

Strawberry is a stand-out cultivating fruit in Korea. The optimum production of strawberry is highly dependent on growing environment. Smart farm technology, and automatic monitoring and control system maintain a favorable environment for strawberry growth in greenhouses, as well as play an important role to improve production. Moreover, physiological parameters of strawberry plant and it is surrounding environment may allow to give an idea on production of strawberry. Therefore, this study intends to build a machine learning model to predict strawberry's yield, cultivated in greenhouse. The environmental parameter like as temperature, humidity and CO₂ and physiological parameters such as length of leaves, number of flowers and fruits and chlorophyll content of 'Seolhyang' (widely growing strawberry cultivar in Korea) were collected from three strawberry greenhouses located in Sacheon of Gyeongsangnam-do during the period of 2019-2020. A predictive model, Lasso regression was designed and validated through 5-fold cross-validation. The current study found that performance of the Lasso regression model is good to predict the number of flowers and fruits, when the MAPE value are 0.511 and 0.488, respectively during the model validation. Overall, the present study demonstrates that using AI based regression model may be convenient for farms and agricultural companies to predict yield of crops with fewer input attributes.

The smart farm for livestock, in which information and communication technology (ICT) is combined with livestock farm, is mostly based on the cloud computing paradigm. A cloud-based smart livestock farm has disadvantages such as increased response time, burden on cloud resource caused by the increased number of IoT sensors, traffic burden on the network, and lack of failure resilience mechanisms through collaboration with adjacent IoT devices. In this paper, with these problems in mind, we propose an IoT collaboration system based on edge computing. By using the relatively limited computing resources of the edge device to share the cloud's web server function, we aim to reduce the cloud's resources needed and improve response time to user requests. In addition, through the heartbeat-based failure recovery mechanism, IoT device failures were detected and appropriate measures were taken.

The existing PC-based desktop environment is being changed to a server-based virtual desktop environment due to various advantages such as security, mobility, and upgrade cost reduction. In this paper, a virtual computing lab service system which is applicable to the existing computer lab is designed and implemented using both an open source-based cloud computing platform and hypervisor. In addition, a node power scheduler is proposed in order to reduce power consumption in a server farm. The experimental results show that the power scheduler reduces power consumption considerably over the server farm without the power scheduler.
