Abstract:
An apparatus and method for controlling lighting in a plant factory are disclosed. The apparatus includes a weight calculation unit, a height calculation unit, a light information extraction unit, and a distance control unit. The weight calculation unit calculates the weight of at least one crop being cultivated based on a sensing result received from a weight sensor disposed in a crop cultivation bed. The height calculation unit calculates the height of the crop based on information about the growth of the crop corresponding to the weight of the crop. The light information extraction unit extracts information about artificial light corresponding to the height of the crop based on the information about the growth of the crop. The distance control unit controls the height of an artificial lighting device based on the information about artificial light.
Abstract:
Disclosed herein are an apparatus and method for managing the growth of crops by individually monitoring the growth state of crops produced in a greenhouse or plant factory. The crop growth management apparatus includes a weight measurement unit configured to measure the weight of a crop that is being grown using the tension of a support string connected to the crop, a crop growth and development management unit configured to determine whether or not the growth and development state of the crop or the weight of the crop is proper based on the measured weight of the crop, and an environment control unit configured to locally control a crop cultivation environment based on a result of the determination regarding whether or not the growth and development state of the crop or the weight of the crop is proper.
Abstract:
A platform apparatus for an agricultural environment control system includes an application support layer unit configured to generate and execute an environment task for supporting an application corresponding to an environment to which the agricultural environment control system is applied, a service layer unit configured to provide service libraries used in the application, a function layer unit configured to perform functions necessary to execute the application, a dynamic adaptation layer unit configured to define the environment task in an application layer irrespective of the number of sensors and actuators installed within the environment to which the agricultural environment control system is applied, and a physical abstraction layer unit configured to generate a mapping table using abstraction results of the sensors and the actuators and enable the agricultural environment control system to access the sensors and the actuators through the mapping table.
Abstract:
An apparatus and a method for managing a reflecting plate for a fruit tree are disclosed. The apparatus for managing a reflecting plate for a fruit tree includes: a solar sensor configured to sense the amount of sunlight; a fruit-tree database configured to store therein types and locations of fruit trees grown in a growing area; a wireless communication unit configured to perform communications with a robot for moving a reflecting plate for a fruit tree and with the reflecting plate via a wireless communication network; and a central processing unit configured to control the robot so that it installs the reflecting plate in the growing area and to control a reflection angle at which the sunlight is reflected in the reflecting plate, based on at least one of the amount of sunlight, the types and locations.
Abstract:
An apparatus and method for non-destructively diagnosing crop growth using terahertz waves are provided. The apparatus includes an information extractor configured to extract status information on a crop from information on an image of the crop taken using terahertz waves, a database configured to store growth-stage-specific information on the crop, and a status determiner configured to compare the status information on the crop extracted by the information extractor with the growth-stage-specific information stored in the database, and determine the degree of growth of the crop.
