1. [제1세부] 시설작물의 최적 환경관리 및 제어모델 개발
◦ The protected cultivation involves artificially constructing and controlling cultivating conditions suitable for the growth of crops and it provides a merit of managing the environment to the optimal in which crops are best suited for growth. Complex environmental control means the ability to control environmental elements within the facility using control devices based on environmental data and growth data. However, the complex environment controller is currently increasing the inconvenience of farming households due to the complicated methods of use and maintenance without effective support. Therefore, in order to cover these shortcomings, it is necessary to develop an optimum growth management model for crops in the facility.
◦ The purpose of this study is to establish the Optimal Environmental Control Settings Table for the control decision system, which is a part of the development of the integrated complex environment controller. This standard includes environmental settings for optimum growth of tomatoes, such as temperature, light and CO2 concentration. It was developed to assist the use of the complex environment controller by the farming households.
◦ Appropriate guidelines are required for each crop to operate a complex controller and it should consider the environment, such as the size of each farm facility. Currently,however, the vast majority of farm households are cultivating their crops without being provided with proper guidelines, despite the lack of unified environmental facilities. Therefore, this study suggested the methods and decision supporting modules to derive optimal environmental control data from these conditions.
◦ The decision supporting module suggested in this study utilizes the environmental data and growth data provided by each farmer's facility to apply the best optimal environment control data and regulates the amount and timing of forwarding. It also provides information on diseases and pests, physiological injury and environmental problems, and builds a database for professional know-how. However, in order to derive optimum environmental data and maximize productivity, each farmer needs many years of collection of environmental control data and the initial data requires verification from experts and professional organizations
◦ The intelligence system for protected cultivation was developed to support efficient use of controllers in households that use complex environmental controllers. The system also incorporates a growth model to simulate the estimated growth resulting from variation of environmental control values.
◦ In conjunction with a complex environment controller, it monitors the current status within the greenhouse and provides alarm information for emergencies. Furthermore, it is possible to analyze the history of cultivation to enhance the environmental control technology. Farmers can inquire the disease and pest information base on symptoms by linking the growth diagnostic system.
2. [제2세부] 최적 환경 및 제어 시스템 개발
◦ The omplex environmental control system currently used in the green house is operated under general control rules, not based on DB (knowledge-based) control.
Therefore, it is necessary to build a database of growth information (expert advice, actual operational data, documents, etc.) for targeted crops and to deliver growth information and control based on the growth status of the crop.
◦ Moreover, it is needed to develop a growth control model using the correlation analysis between the dynamic growth amount of the facility crops and complex environmental factors, and a decision system to generate the optimal environmental conditions based on the model. Therefore, we want to develop and improve quality and productivity by developing a complex control technology for the greenhouse environment based on the developed ICT in Korea.
◦ In this study, various decision support systems were examined, and the necessity,characteristics and examples of decision support systems in the field of agriculture were studied. The basic structure of the decision support system is composed of the user, database, model bases, knowledge base, and method bases. The agriculture decision support system provides information that enables the agricultural producers to make various decisions suitable for cultivation conditions, and consists of three large axes : a agricultural intelligence system, agricultural production models, and agricultural expert systems.
◦ This study introduced the basic structure of the decision support system and detailed description of the model base, which is a characteristic of the decision support systems in the field of agriculture. Also, we compared various domestic and foreign decision support systems for agriculture and discussed the need for developing a decision support system to optimize the industrial structure of agriculture.
◦ The decision support system provides information that allows unfamiliar farmers to use complex environmental controllers more effectively, and the accumulated cultivation experiences are stored in the form of knowledge base and support users. The decision support system was developed based on the Java-based implementation environment, the main technology elements are spring framework, hibernate, Ajax, JSON and Amchart. The decision support system searches the knowledge base that has been developed in the Task Team No 1 with the real-time collection of environments and control information and determine whether controls are relevant or not and provides users with control information.
3. [제1협동] 생육 진단 및 일반 예측 모델 개발
◦ Crop growth simulation model would be employed as a useful tool for decision-making in greenhouse crop production. Simulation of crop growth using a crop model would be useful to optimize control of climate conditions within a greenhouse. The objective of this research project is to develop crop growth models for greenhouse tomato and chrysanthemum.
◦ The mechanistic tomato growth and development model were developed to simulate the growth of stem, leaf, root and fruit, and the development of leaves, leaf area,flowers and fruits by using the weather data inside the greenhouse. The model for growth and development of tomato consists of modules for calculation of radiation transfer, energy balance within a greenhouse as well as photosynthesis and phenology.
In simulation of transpiration, aerodynamic resistance was calculated using empirical equation. For simulation of photosynthesis, leaf temperature obtained from energy balance equation was used. Using air temperature within the greenhouse, growing periods and flowing timing were also determined. The model was designed and programmed in JAVA script to provide the simulation outputs through memory in order to interface with a controller of greenhouse for optimum conditions, e.g.,ventilation, shading or warming. Objective oriented programming approach was used to design a simple tomato model. The model developed were proved to simulate the growth and development of tomato very realistically in a greenhouse climatic condition. However, the model could not simulate tomato growth and development when management options such as defoliate, flower thinning were conducted. This results indicated that further calibration would be needed to improve accuracy of the model.
◦ Chrysanthemum is a typical short day plant of which floral initiation and development is sensitive to photoperiod. We developed a model to predict phenological development and leaf appearance of chrysanthemum (cv. Baekseon) using daylength (including civil twilight period), air temperature, and management options like light interruption and ethylene treatment as predictor variables. Chrysanthemum development stage (DVS) was divided into juvenile (DVS=1.0), juvenile to budding (DVS=1.33), and budding to flowering (DVS=2.0) phases for which different strategies and variables were used to predict the development toward the end of each phenophase. The juvenile phase was assumed to be completed at a certain leaf number which was estimated as 15.5 and increased by ethylene application to the mother plant before cutting and the transplanted plant after cutting. After juvenile phase, development rate (DVR) before budding and flowering were calculated from temperature and day length response functions, and budding and flowering were completed when the integrated DVR reached 1.33 and 2.0,respectively. In addition the model assumed that leaf appearance terminates just before budding. This model predicted budding date, flowering date, and leaf appearance with acceptable accuracy and precision not only for the calibration data set but also for the validation data set which are independent of the calibration data set.

◦ It is not easy to decide to the growth state of the products by the farmers. In case of the disease, pest and poor growth, they are needed the expert knowledge to decide. If they dose not take measures, the production will be decreased.
◦ In this paper, we studied and developed the expert system to assist on the decision about the growth state to the products. There are many kinds of growth state such as, disease, pest, poor growth, vegetation status, and reproductive status. Firstly we made a model about the growth diagnosis system for tomato. For the diagnosis, we defined the key index which affect to the growth of the tomato, Using the key index, we can make a diagnosis the status of the growth and take action to tomato. The index consist of Measure Index(MI) which is used to confirm the status of the tomato using the continuous growth check and Period Index(PI) which decide to the step whether vegetation period or reproductive growth period of the tomato.
◦ Another system, we developed the expert system about the disease pest, vegetation disturbance, reproductive disturbance in tomato and chrysanthemum.
◦ As a result of the system, we constructed 20 disease DB, 7 pest DB, 6 vegetation disturbance DB, 22 reproductive disturbance DB in tomato. also we constructed 9 disease DB, 8 pest DB, 11 vegetation disturbance DB, 11 reproductive disturbance DB. Using the system, farmers can decide the exact status of the products and take measures of the diagnosis prescription.
