Study on precision irrigation technology of large scale irrigator
Spray Irrigation is much better in water-saving and yield-increasing than other irrigation methods. Large scale linear move spray irrigation system is widely used in China. But the traditional go-stopgo driving method make it hard to control and get bed irrigation efforts, thus new control way with high efficiency and low consuming is needed. Because of the difficulty of real examination, virtual reality is used to simulate the controlling and driving system in this thesis. Build 3D models of the irrigation system departments according to their scale with Pro/ENGINEER, and 3D scenes of farmland with Multigen Creator, as well as mechanical models of the irrigation system according to the principles of ground vehicle dynamics. Visual C++ 6.0 and Multigen Vega were used to program an application, which load models of irrigation system into virtual scenes, then simulated the control system and drive system to monitor in real-time. Examinations shew that parameters got from the system can keep each tower run in a line with angle error of less than 0.06°.
