This design mainly aims at a control system with lower automation situation used in green house, by deeply analyzing green house executing equipment cause the influence for environment factor, Applying fuzzy control ,single-chip control and communication technology to design and research the control system of green house ,and developing an intelligence fuzzy control system of green house. So as to measure and control temperature and humidity of greenhouse.The fuzzy logic control system of the intelligent greenhouse condition is a complex system. It's difficult to set up a mathematic model. Using normal control method, hardly get a satisfying dynamic and static performance. In this design we use fuzzy control based on membership function and fuzzy composing principle, moreover, add the people's intuition. Fuzzy control can effectively control tile non-linear, complicated and multi- variable system whose parameter are fluctuant and signals aren't accurate, so using fuzzy logic control so it fits environment of green house control.This system composes of PC and single-chip computer SPCE061A and periphery circuit, fuzzy logic control algebra is finished with PC , fuzzy logic strategy adopts tabulation check;temperature and humidity measuring and real time control is finished with SPCE061A and periphery circuit , temperature and humidity sensor adopts single bus DS18b20 and IH3605. emulation cure shows that it can control fast and effectively ,and it proves that the scheme is doable.
