Field Bus and Design Scheme for Greenhouse Intelligent Control System

This paper introduces the field bus and international standards relating to it. As well, it analyzes the international and domestic development trend of the field bus, expounds the significance of using the field bus in intelligent control of greenhouse and examines the corresponding countermeasures. The hardware for the greenhouseinte lligent control, which includes the overall layout of the design of the master interface board, the intelligent transmitter and the intelligent controller were designed.
