In this paper, we have implemented Green House automation system. The system should be kept in optimal condition in real-time by checking the greenhouse environmental conditions in the greenhouse. In addition, it can be converted to temporarily the necessary equipment by converting to manual mode in the environment you want. Environmental data collected from the greenhouse is sent to your computer monitor, as well as it support the web-based system to enable immediate control through the web. Users can view the situation of the greenhouse in real time by using a web-based system and maintain automation features by deciding specified conditions for a greenhouse environment.

기존의 인력을 동원하던 거의 대부분의 일들을 기계를 이용한 자동화 시스템으로 대체되고 있으며, 대체된 자동화 시스템은 작업의 효율성과 정확성으로 성능이 평가되고 있다. 본 논문에서는 농업분야에 응용하기 위한 온실제어 자동화 시스템을 개발하였다. 온실 온도제어 자동화 시스템은 보다 정확한 온도 제어와 습도 제어 기능을 가지고 있어야 하며, 오동작으로 농작물의 피해가 발생할 수 있으므로 오차의 최소화 기능도 필요하다. 이러한 모든 기능을 제어하기 위하여 AT89C51이 사용되었다.

Environmental control operations have been considerably contributed to the reduction of labor cost in both plastic film and glass greenhouses since government supported projects were begun. However, some problems are still remaining on the optimal environmental control and excessive operation due to an inflexible software regulating ventilation gear - reducers. The unadjustable software caused the damage of ventilation system, resulting in heat stresses of crops. This study was performed to develop a ventilation software controlling the vent opening level, opening sequence, based on the wind direction, and control interval according to the difference between ambient and set- up temperatures. The software included a beeper system alarming urgent cases, while a manager was remote from the greenhouse. A compatible hardware with the software was also developed by using a low-cost diffused DSP controller.

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.

오프라인에서만 가능했던 일들이 인터넷 속도의 향상으로 온라인을 통한 실시간 제어가 가능해지고 있다. TCP/IP를 기반으로 이루어지는 경우 대개 소켓을 이용한 PC기반에서 해석되어 지고 처리되어 진다. 본 논문에서는 PC기반의 원격제어 시스템을 임베디드화하여 온실시스템에 적용해 봄으로써 시스템의 안정성과 효율성에서 우수한 시스템을 구현하려고 한다. 이를 위하여 임베디드 시스템은 웹서버의 기능을 가진 HelloDevice 1300보드를 이용하였다. 실질적인 제어물의 제어를 위해서 제어기를 HelloDevice 1300보드와 시리얼을 통하여 통신하였다. 이와 같은 시스템을 구현하여 온실시스템의 자동화에 관한 실효성을 검증하였다.

The automatic irrigation system using the stem diameter monitoring and the transpiration model for the determination, respectively, of irrigation timing and amount was designed and evaluated for its applicability in pot and field culture of greenhouse tomato. In the pot culture condition, the yield and quality of greenhouse tomato were improved when irrigation was practiced based on the stem diameter monitoring and the transpiration model as compared to the irrigation practice based on soil moisture monitoring. However, the effects were not significant in the field culture condition.

Agricultural machine is currently operated by man power in the greenhouse, which is oppressively hot and humid, and is for a farmer not to work in comfortable circumstances. In the future, agricultural machine will not have to operate by man power, but it will need do by unmanned power. In order to put into the automatic and unmanned operation of agricultural machine, this system was designed and built to move through the fixed path in the greenhouse. This system was composed of guiders(wires), a limit switch, an operating equipment, its software for automatizing a machine in the greenhouse. The guider was connected between the wall pillars, and the equipment was able to slide over the fixed path made of the guider, by rectilinear and rotational motion. A micro mouse was developed with a stepping motor to calculate on the success rate of its operation with the system As might be expected, this system with the micro mouse was moved the moved the paths with a success rate of 100% on the flat plane surface in our laboratory. However, on the sand plane or the other materials plane, the success rate was not better than 80%. If the micro mouse were well operated, the success rate was would be 100%. Based on the results of this research, this system would be expected to operate well on the path made of a simple wire.

Recently, a study on the development of remote monitoring and automation control system based on Web is spread widely. In this paper, we have expended the remote control method on the existing automation. And we proposed method to do real-time monitoring and remote control considering multimedia data processing, the expansion of TCP/IP using LabView graphical language. Also we applied the method in greenhouse environment control system. The application result was evaluated by very efficient thing to remotely monitor and control situation of greenhouse.

재배시설내의 재배면적은 온실의 경우 벤치의 구성 방법에 따라서 차이는 있으나 바닥 면적의 47-68% 정도로 전체 면적에 비하여 생산에 사용되는 면적의 효율이 높지 못한 편이다(Langhans, 1990). 이러한 재배면적을 최대로 확보하여 단위 면적당 생산량을 높이기 위한 연구가 자동화 온실이나 식물공장을 중심으로 진행되고 있다. 이러한 연구는 많은 성과를 거두고 있으나 인공광을 이용하거나, 부가적인 기계화 장비나 자동화 설비가 필요하여 에너지 비용과 시설비용이 무시 못 할 정도이며, 고도의 제어기술이 요구되고 있어 상업용으로 보급되지 못하고 있다.
