Plant factory industry as a new agriculture is in the spotlight. In this paper, we experimented plant factory applied photovoltaic system and LED lighting. For growing the plant, red, blue and white LED were placed into 1:4:3. Electric power generated by the photovoltaic system was supplied on DC power supply instead of AC. The designed and experimented power generation amount per day of photovoltaic system were 2,860 Wh and 2,272 Wh respectively. Plant has not been grown at the dead space of LED lighting so it is required to array LED lighting.

The importance of plant factory which blend agriculture and manufacture has been discussed widely. This company has researched hydroponics technique for cultivation which has been mainly developed in the sites of Okinawa and Hyougo Prefecture. In 1987, we stopped the previous research there, and started a new one far plant factory at the Agricultural Research Center of Chiba Prefecture. In 1989, we built four experimental plant factories (120㎡) at Chiba Oil Factory Refinery in Ichihara-city, developing techniques of cultivation, equipment production and environmental control for cultivation system of tomato, strawberry and leaf vegetables.

A plant factory system is getting the spotlight as alternatives to cope with the weather anomaly and food crisis because of the global warming. A study on 'Plant Processing Factory System' has been proceeded to develope 'low-carbon green growth' since our government selected it as the green technologies in 2010. The plant factory has played a major role in growth industries connected to many other fields like low-carbon as well as lighting and automated system. This study is aimed to solve the problems on low productivity and health problem of plant workers caused by highly concentrated carbon dioxide and low temperature in each process in the plant factory. It is aimed to research data to understand the actual conditions of plant workers and improve the thermal environment.

식물공장 (plant factory)은 파종에서 재배 및 수확까지 실내에서 종합적으로 관리 제어되는 공장식 식물생산기술로 현대농업의 결정체이다. 식물공장은 청결한 환경에서 안전성 높은 농산물을 연중 생산할 수 있고, 작업환경이 좋아 노동력 확보가 수월하다. 선진국들은 수 십년 전부터 식물공장의 산업적 경제적 효과를 예측하고 이 분야에 많은 관심을 가지고 적극적으로 투자해 왔다. 최근 우리나라도 우수한 기술력과 인력을 적극 활용하여 국제 경쟁력이 있는 식물공장 시스템을 개발하고자 활발히 연구개발을 진행하고 있다. 식물공장은 초기투자비용의 과다, 전용 품종의 재배기술 부족, 운영비 절감 등의 문제점이 아직 해결되지 않아 기존 농업과 경쟁하기 어렵다. 그러나 식물생명공학 분야의 전문가들이 식물공장 시스템 개발에 적극 참여한다면 여러 문제점이 개선될 것이다. 환경변화에 의한 농작물 경작의 어려움에 당면하고 있는 농촌과 농업에 식물공장을 잘 활용한다면 농산물 경작의 문제점을 해결하고, 식량문제와 환경문제를 해결하는데 큰 역할을 할 수 있을 것이다.

Factory-style plant production system aims to produce the standardized horticultural products with high quality and cleanness. In Korea, researches for year-round leaf vegetables production system are in progress and the most of them are focused on environment control. Automating technologies for harvesting, transporting and grading need to be developed. A lettuce harvesting system applicable to the plant factory was studied. It was composed of an articulated robot with a cutter and a gripper, lettuce feeding conveyor and air blower. Success rate of the developed system was 94.7 %. The system carried out harvesting a lettuce smoothly and the harvesting time was about 6 seconds per lettuce. The results showed a feasibility of robotic lettuce harvesting.

Microprecision agriculture for a fully controlled plant factory is proposed in this paper. Microprecision agriculture can be attained by using plant factories to realize profitable alternative agriculture. A closed, fully controlled, plant-growing factory is far better in terms of minimizing all sorts of waste. The limit and optimum design concept has to be applied to establish an economically feasible, fully controlled, plant-growing factory. To achieve this objective, microprecision technologies have to be developed. Microprecision technologies should be involved in sensing, modeling, controlling, and collecting information for the mechatronics for plant production. Basic technologies for microprecision are already available; they are SPA (speaking plant approach to environmental control), AI (artificial intelligence: expert systems, neural networks, genetic algorithms, photosynthetic algorithms etc.), bioinstrumentation, non-invasive measurement, biomechatronics, and biorobotics. A microprecision irrigation system for plug production is an example of a microprecision technology that has actually been implemented in a plug seedling production factory.

Recent researches on plant factory system deal with the convergence of lighting technology, agricultural technology inclusive to the high-tech industries worldwide in order to respond to the decreasing crop harvest due to global warming and abnormal weather phenomena. However, the fundamental performance standard is not currently being introduced in the case of plants factory and its commercialization is not activated because of high initial investment and operating cost. Large portion of the initial investment and operating cost of a plant factory is ascribed to artificial light sources and thermal control facilities, therefore, innovation should be provided in order to improve the economics of the plant factory. As an alternative, new plant factory could harness solar thermal and geothermal systems for heating, cooling and ventilation. In this study, a natural light dependent multi-layer plant factory's thermal environment was analyzed with two-dimensional numerical methods to elicit efficient operation conditions for optimized internal physical environment. Depending on the supply air temperature and airflow rate introduced in the facility, the temperature changes around the crops was interpreted. Since the air supplied into the plant factory does not stay long enough, the ambient temperature predicted around the plating trays was not significantly different from that of the supplied air. However, the changes of airflow rate and air flow pattern could cause difference to the temperature around the planting trays. Increasing the amount of time of air staying around the planting trays could improve energy performance in case the thermal environment of a natural light based multi-layer plant factory is considered.

1960년대에 유럽에서 출발한 식물공장은 종자학, 양액 기술, 환경제어 기술, 자동화시스템 등 관련 기술의 발전에 힘입어 완전인공광형 식물공장의 형태로 발전했으며, 최근에는 ICT 기술과의 융합을 통해 작물 재배의 효율성을 늘려가고 있다. 국내에서도 식물공장에 관한 성과가 도출되면서 식물공장에 대한 관심이 높아지고 있으나 산업 생명주기로 볼 때 여전히 도입기에 머물러 있으며 정부 투자는 점점 줄어들고 있다. 연구자는 식물공장과 관련한 정책, 기술, 사업 분야의 전문가를 대상으로 설문조사를 실시하여 식물공장의 투자 가치를 재분석하고, 식물공장의 경쟁력 강화 방안을 도출하고자 하였다. 본 연구는 식물공장 산업의 기회와 위험요인을 식별하고, 식물공장의 고부가가치 창출을 위한 전략을 제시했다는 점에서 연구 의미를 가질 수 있을 것으로 기대한다.
