【Abstract】 Entering the 21 century, Control technology has a rapid development. But in the controlling field, Fieldbus control technology has come into control field. So, in this paper, Fieldbus control system (FCS) is introduced in greenhouse automation to compose distributed control system of greenhouse, Through its advantages and disadvantages, this paper shows the Fieldbus network?development orientation to industrial Ethernet. And Industrial Ethernet is introduced to the control field, through Ethernet抯 advantages and disadvantages, At last, with the control condition of the latest agricultural engineer greenhouse , this paper gives the applying foreground of industrial Ethernet.26]更多还原
