Light Regulation System for Greenhouse Based on Light Requirements of Crops
Based on the photosynthetic rate model considering the light demand of crops, the influence of temperature on illumination requirements for crops’ growth was analyzed, and then the light supplement model of greenhouse was estab-lished .A remote light environment control system for the greenhouse based on the light needs of crops was designed apply with the wireless communication technology.The lighting regulation method of system was tested according to the change of greenhouse environment in a day in early winter.The simulation results demonstrated that this method can take different lighting control methods on the basis of the change of the environment, and that it cannot only meet the need of plants growth but also can help to make use of energy efficiently.
