An Object-oriented environmental control model in protected cultivation

Abstract A prototype computer model based on object-oriented approaches for environmental control in protected cultivation was discussed. The model handled to convert the control setpoints having generic form into the real manipulations of specific control instruments for measurement and control. The requests for environmental control were realized to send a message to specific object, and the object started to manipulate the control. The model did not need to take notice of any instruments specification, because each instrument specification was controlled by the specific object. A prototype system based on the concept was developed and tested. From the result of testing, the object-oriented approaches provided the prototype system with having flexibility, having reliability and saving development costs.
