Study on Linear Move Irrigation Synchronization Control System in Virtual Scene

Linear move irrigation system is widely used for its water saving and high automatization character, but the traditional go-stop-go driving method made the linear move irrigator hard to control and hard to get good irrigation efforts. Thus new control way with high efficiency in operation and low consuming of water, electricity, other materials and human resource is needed to develop to avoid this problem. Because of the difficulty of examination, virtual reality technology is used to simulate the controlling and driving system in this thesis. Build three-dimension models of the irrigation system departments according to their scale with Pro/ENGINEER, and three-dimensional scenes of farmland with Multigen Creator software. Assemble the departments together to six towers with Multigen Creator and analysis the forces of the 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 the three-dimension models of the irrigation system into the scenes of farmland. Then simulate the control system and drive system to study the moving properties of towers when the alignment angle between two adjacent towers changes. The simulation results show that the system can reflect the large-scale irrigation factually, and can optimize control parameters through simulation.
