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.
