| Abstract:
A system has been designed that permits the interfacing of existing microprocessor based greenhouse environment controllers to a central control computer. The central control computer was specially designed to interface to up to 64 environment controllers, a weather station and a microcomputer equipped with two disk drives. The central control program imposes enhanced control algorithms on each environment controller, displays greenhouse operating status graphically on a display terminal and permits data logging on magnetic disk. A prototype of the system has been constructed and tested in a commercial greenhouse. The system has been proven to be reliable and user friendly. | |
