Research on solar greenhouse intelligent CAD system

An intelligent CAD system for designing virtual solar greenhouse is presented. The system consists of an expert decision system for inferring greenhouse structural parameters and a graphics processing module. Object-oriented knowledge representation is applied to design knowledge case, and cage-based reasoning and production reasoning are used as the reasoning method of the system. The expert-decision system for greenhouse structural parameters can quickly and efficiently produce the design result which corresponds with the desired goals; while the graphics processing module can render 3D models by parameterized case in real-time, and enable the generation of virtual greenhouse animation and visualization computing. The proposed system can be looked as a preliminary realization of intelligent and automatic design of solar greenhouse.
