Simulation and Experiment of Corn No-till Planter Operating Unit in Meta-universe Environment
Aiming at the problems of long R&D cycle and high R&D cost of no-tillage planter for maize,it was proposed to apply the meta-universe technology to the simulation of corn no-tillage planter operating unit.Based on the architecture of the meta-universe system,the simulation platform was constructed,and the scenes in the virtual farm were highly restored under the meta-universe environment by using the marking line method and the transformation method,and an immersive corn no-tillage planter driving platform was constructed and tested for the interactivity,to verify that the immersive corn no-tillage planter driving platform had better interactivity.The interactive performance of the immersive corn no-till planter driving platform was verified to be better.On this,seeding performance simulation tests were carried out at different driving speeds,and the overall seeding quality showed a decreasing trend when the forward speed of the corn no-tillage planter unit was increasing,and the overall trend was close to the actual field test results,and the spacing pass rate was greater than 88.52％,the reseeding rate was less than 6.97％,the omission rate was less than 4.51％.The test results showed that the virtual seeding simulation platform designed and implemented can be used for corn seeding experimental research,which was of great significance to reduce the research and development cost of no-tillage seeding machine and shorten the research and development cycle of no-tillage seeding machine for corn.
