CAD Of Drip Irrigation In Agriculture Facilities

Facility agriculture are well developed now, so many greenhouses or large canopies are set up, it makes the layout of the drip irrigation become so important. But the traditional method requires too much time, too much multifarious calculation, and it is disadvantage to compare and select between several schemes. Thus the traditional way of drip irrigation project brings much trouble to the designer.Visual Basic has friendly interface, strong functions and favorable stability. So this system is developed on the platforms of Visual Basic.NET. It exerts the drawing function of GDI+, doing report forms function of Crystal Reports, founding self-contained data base function of Access. This system utilize the alternant man-machine manner, once the designer input the basic information of irrigative section , it can finish the layout of drip irrigation project. Functions such as planning for the pipe system, water head calculating for the pipe net, type selecting of material, drawing of planning and pipe system figures, automatically producing equipments and budgetary table are characteristics of this CAD (computer aided design) system.In this thesis, the structure, design thoughts, program process of the CAD system of drip irrigation for agriculture facilities are introduced. Eventually, the system was proved feasible through designing several examples.
