This paper adopts microprocessor SOPC and wireless sensor network to design an intelligent real-time greenhouse monitoring system. Data acquisition and transmission is realized via the wireless sensor network. The fuzzy-PID controller, designed on the SOPC, analyses environmental information and controls the air conditioning compressor. Data can be collected and transmitted on the hardware of the system. Programming is completed via Verilog HDL to realize the design of the fussy-PID controller. Simulation of the fussy-PID controller is made through MATLAB. The result shows that the fuzzy-PID controller has the advantages of high precision, quick response and strong robustness in its control over nonlinear time-varying systems.
