본 논문에서는 가정에서 식물 재배 환경에 따라 설정이 가능한 스마트 IoT 온실을 개발하였다. 개발한 온실은 사용자가 웹을 통하여 원하는 식물을 선정하면 자동으로 미니온실의 온도와 습도가 맞춰지도록 개발하였다. 온도와 습도, 물주기까지 사람이 직접 관리하는 것이 아닌 웹으로 원격 제어가 가능하기 때문에 높은 정확도와 편리함 속에서 식물을 좀 더 오랫동안 쉽게 기를 수 있을 것이라 기대된다.

Recently, in digital agriculture, the types and utilization of greenhouses based on IoT are spreading, and greenhouses are being modernized, enlarged, and even factoryized using smart technology. However, a specific standardization plan has not been proposed according to the equipment for data collection in the smart greenhouse and the size or shape of the greenhouse. In other words, there is a lack of standard data for facility equipment, such as the type and number of sensors and equipment according to the size of the greenhouse, the type of greenhouse construction film and materials suitable for crops and carbon neutrality. Therefore, in this study, the suitability of the implementation, installation and quantity of IoT equipment for data collection was tested, and some standard technologies were presented through the implementation of data collection and communication methods. In addition, impact strength, tensile, tear, elongation, light transmittance, and lifespan issues for PE, PVC, and EVA, which account for about 90% of existing greenhouses, were presented, and the shape, size, and environmental problems of greenhouses made of films were presented. presented in the text. In this research paper, a standardized carbon-neutral modular smart greenhouse using nano-material film was implemented as a solution to environmental problems such as greenhouse size, farm crop type, greenhouse lifespan, and film, and its performance with existing greenhouses was analyzed and presented. Through this, we propose a modularized greenhouse that can be expanded or reduced freely without distinction in the size of the greenhouse or the shape of farmhouse crops, and the lifespan is extended and standardized. Finally, the average characteristics of greenhouses using existing PE, PVC, and EVA films and the characteristics of greenhouses using new carbon-neutral nanomaterials are compared and reviewed, and a plan to implement an expandable IoT greenhouse that supports carbon neutrality is proposed.

IoT(Internet of Things) 기술이 급속도로 발전함에 따라 다양한 분야에 적용되고 있으며, 새로운 부가가치를 창출하고 있다. 최근에는 IoT 기술을 접목하여 도시 내부에 자동화된 농작물 재배시설을 설비하여 재배된 농작물을 직접 현지에 바로 공급할 수 있는 운영시스템을 구축하고 있다. 본 연구는 도심지 내부의 건물 옥상이나 농작물을 재배할 수 있는 임의의 공간에 온실을 설치하여 작물을 재배할 수 있는 환경을 원격으로 관리하는데 있다. 온실 내부의 환경 데이터를 계측하기 위한 온도, 습도, 조도, 토양상태, CO2 센스를 설치하여 온실 내부의 환경을 라즈베리파이2(raspberry Pi2)를 활용하여 계측하였다. 원격으로의 데이터 전송은 Wi-Fi를 이용하여 데이터를 전송하였으며, 중앙에서 관리된 관리정보를 통하여 온실 하우스의 내부 환경을 제어할 수 도록 모터(motor), 환풍기 팬, 조명용 Led, 워터 펌프 등을 제어하도록 하였다. 본 논문의 연구결과를 통하여 비닐하우스의 내부 상태를 계측하고, 다양한 구동장치를 제어할 수 있도록 IoT 기술을 편리하게 적용할 수 있는 라즈베리파이와 원격관리용 스마트 앱(app.)을 이용하여 비닐하우스 내부 관경을 편리하게 관리할 수 있음을 확인하였다.

현재까지 IoT 관련 기술들은 수많이 발전해왔다. 하지만 IoT 관련 기술들이 농업에 적용된 사례는 많지 않다. 이로 인해 농업에서는 자동화로 대체가 가능한 노동들이 여전히 사람들이 직접 하고 있다. 본 논문은 농업에 종사하시는 분들의 편의성 증대와 함께 농촌의 부족한 노동력을 충족시키기 위해 센서들을 이용하여 자동화된 농업 시스템인 '온실 환경 자동 케어 시스템'을 제안한다. 기존의 사람의 노동력을 이용한 방식이 아닌 컴퓨터가 센서와 상호작용을 하여 데이터를 처리하고 온실을 제어하여 농업 종사자들의 편의성을 증대시켜 나아가 농업의 부족한 노동력을 충족 시킬 수 있다.

In this paper, we proposed a smart greenhouse system that can easily grow plants indoors without professional knowledge by using the criteria of factors affected by common plants (temperature, humidity, soil humidity), and implemented a system that can check the greenhouse state in real time and control the device remotely through mobile applications. Based on Raspberry pie and Arduino, the system measures the state of greenhouse in real time through sensors and automatically controls the device. After growing and experimenting with plants in a greenhouse for a certain period of time, it was confirmed that the environment suitable for each plant was maintained. Therefore, the smart greenhouse system in this paper is expected to improve plant cultivation efficiency and user convenience and also increase beginners' access to plants.

Under the Agricultural technology is influenced from climate that is requisite of seasonal. So this system will cover the problems and develop the agricultural industry as well. So far, the agricultural industry is developing however, it has the points of the weakness because of natural disasters such as wind risk and heavy snow. This paper designs system to change vinyl on the greenhouse. This is a preliminary study for the real-time feedback control of greenhouse. The study developed a wireless IoT sensor system based on authentic technology capacities, to integrate with the protected horticulture Management System. These system was used to evaluate the levels of the snow cover and wind through IoT devices. The existing greenhouse uses the warm water to clear snow or to change methods. This system will recover by changing the vinyl which is covered outside of the greenhouse. The points of the system is changing vinyl to spin pipe. It is contained extra vinyl. The effects of this system are minimized labor protected crops from natural disasters. For this purpose, the study first developed a wireless IoT sensor unit that integrates an MEMS device and wireless communication module. Also, the study developed an operating program that enables real-time response measurement. It will help operational and maintenance greenhouse as a result.

In the Paris Climate Agreement, Korea submitted an ambitious goal of reducing the greenhouse gas emission forecast (BAU) by 37% by 2030. And as one of the countermeasures, a smart grid, an intelligent power grid, was presented. In order to apply the smart grid, EMS(Energy Management System) needs to be installed and operated in various fields, and the supply is delayed due to the lack of awareness of users and the limitations of system ROI. Therefore, recently, various data analysis and control technologies have been proposed to increase the efficiency of the installed EMS. In this study, we present a measurement control algorithm that analyzes and predicts big data collected by IoT using a SARIMA model to check and operate energy consumption of public sports facilities.

Smart farm technology using IoT is one of the technologies that can increase productivity and improve the quality of agricultural products in agriculture, which is facing difficulties due to the decline in rural population, lack of rural manpower due to aging, and increase in diseases and pests due to climate change. . Smart farms using existing IoT simply monitor farms, implement smart plant growers, and have automatic greenhouse opening and closing systems. This paper implements a smart farm system based on MQTT, an industry standard protocol for the Internet of Things, and Node-RED, a representative development middleware for the Internet of Things. First, data is extracted from Arduino sensors, and data is collected and transmitted from IoT devices using the MQTT protocol. Then, Node-RED is used to process MQTT messages and store the sensing data in real time in MongoDB, a representative NoSQL, to store the data. Through this smart farm system, farm managers can use a computer or mobile phone to check sensing information on the smart farm in real time, anytime, anywhere, without restrictions on time and space.

Recently, the agricultural environment in Korea is rapidly changing due to the aging and decline of the agricultural population, and in order to solve these problems, it is urgently required to improve the agricultural productivity and reduce the labor force. To solve this problem, a smart farm fused with ICT technology is being proposed as an alternative. In Korea, smart farms are currently mainly used in greenhouses. In this paper, this smart farm technology is to be applied to the cultivation of sprouted ginseng. To this end, we use seedlings (about 1.0g) to grow a solid medium and bed for cultivating sprouted ginseng, a fresh ginseng that is produced in a short period of time (2~3 months) with a clean environment management technology that does not use chemical pesticides and hydroponics in a greenhouse developed. In addition, an IoT-based growth environment management system was developed to monitor the growth process of sprouted ginseng in such an environment and to control driving devices.
