CAD System Of Little Sprinkling Irrigation

The planning of little sprinkling irrigation project to the greenhouse or the large canopy by hand , it involves inquiring about a large amount of basic materials, much multifarious calculation, uninteresting drawing work. In the process of planning a parameter modification often needs to recalculate many parameters again that have been defined, it is a repeating work, and apt to make mistakes,and the Labour intensity is great,Design cycle is long and Efficiency is low.This system can automatically realize the little sprinkling irrigation project planning in the form of CAD, it overcomes the shortcoming of that planned by hand. It offers the friendly man-machine interface. It can finish the reading of greenhouse or canopy,choice of parameter, calculation of water conservancy, type -selecting of material, and the outputs of drawings and the report form of parameter. Compared with the situation that planned by hand, it reduces the labour intensity, shortens the period of planning, improves working efficiency.AutoCAD has strong graph processing functions, and has many kinds of programming interface,so the system is developed on the platforms of AutoCAD2000. the content of developping the systen involves: Setting up basic materials data base, the theory in the Planning of little sprinkling irrigation project, the visit of AutoCAD target, the visit of the data base ,and the combination techniques of AutoCAD and "Visual Basic etc.
