自走式大豆表型采集平台底盘设计及试验
Platform Chassis Design and Test of Self-propelled Soybean Phenotype Information Collection
摘要
Abstract
In view of the poor universality of the existing crop phenotype detection platform,which can not be applied to the ridge planting and dense planting of soybean in the northern cold region,in order to improve the efficiency and accura-cy of soybean phenotype detection,a self-propelled soybean phenotype information collection platform chassis that can achieve stable walking and precise positioning between ridges is designed.The structure is designed according to the planting mode and growth characteristics of ridge soybean,and the Siemens SMART 200PLC is used to control the walking system and phenotypic information collection system.The performance of the platform chassis is tested through field tests.The results show that the average deviation rate on the cement pavement is 0.047%and the average deviation rate between ridges is 0.072%when the driving speed between the cement pavement and the ridge is 0.5 m/s.The average standard deviation of positioning between cement pavement and ridge is 12.7 and 3.05 respectively;the average relative standard deviation was 10.7%and 7.2%respectively.It can realize stable walking and precise positioning between ridges,and provide technical support for phenotypic information detection of ridge soybean.关键词
