Research on Loss Monitoring of Grain Cleaning in Combine Harvester Based on Kalman Filter
摘要
Abstract
In order to reduce the impact of interference signal code of cereal grains , achieve real-time monitoring work combine harvester process quantity , and improve the monitoring accuracy , it designs a new seed sorting and monitoring system .The system uses the method of Kalman filtering to shorten the decay time of the impact plate grain collision sig-nal , which can effectively reduce the interference problem between signal code .In order to verify the validity and relia-bility of the system , the grain cleaning system has been tested by choosing two groups of different grain plumpness degree as the research objects .Through the test has been bombarding voltage response curves of two groups of grain .Finally , respectively Kalman filter and the unfiltered signal attenuation curve and grain cleaning error , by contrast the results , it can be found that Kalman filter can shorten the signal decay time obviously , which reduces the influence among grain in-ter symbol interference on the system monitoring precision , and reduces the cleaning error .And it greatly improves the grain loss monitor of the working efficiency in the system , which provides the theory reference for optimization design of combine harvester .关键词
