Design of Autonomous Navigation No-till Planter Based onSensing and Inofrmation Collection
摘要
Abstract
In order to enhance the automation of no-till planter, a new no-till planter having function of autonomous navigation and path planning has been designed, the planter can good estimate the number of the incoming signal and di-rection, and overcome the shortcomings of traditional low positioning accuracy, which can effectively solve the dense sig-nal environment, multiple sources of high resolution, high accuracy direction-finding location problem.In order to verify the performance of no-till planter,the use of signal DOA estimation of seeder was carried out after the performance test, through test,found that the seeding error significantly less than simply using least square method and hyperbola method, seeding rate reached 98.7%, the highest coefficient of variation of the lowest 1.35%, seeding accuracy and high stabili-ty, and design in this paper by comparing the sowing time of traditional planter, the planter designed in this paper sowing time was shortened, sowing efficiency has improved greatly, the no-till seeding performance is good, which can be repli-cated in automation in the planting operation.关键词
