The Research and PLC Application of Fuzzy Control in Greenhouse Environment

Aimed at the single control parameter and low degree of automation of traditional green house, the paper researched fuzzy control system based on multi-factor control of green house. With real-time monitoring environmental parameters, and based on the physiological characteristics of crops and the reaction of the environmental conditions in the green house, the fuzzy control algorithm is applied to PLC program to be adjusted within the environment in the green house, which promotes photosynthesis, inhibits respiratory consumption, accelerates the transport and accumulation of nutriment to increase energy and improve utilization efficiency of green houses.
