主 题：precision agriculture combine harvester yield monitoring system sensor grain flow rate
摘 要：Real time sensing of crop yield is critical for a successful implementation of precision *** monitoring system is an optional component of a 55 kW multi-purpose combine harvester,developed in Korea,for both domestic and global markets,especially Asian countries where field sizes are relatively *** aim of the present study was to fabricate and evaluate the performance of a grain flow sensor suitable to the mid-sized full-feed type combine for rice,soybean,and ***,commercially available non-contact type sensing modules(optical,ultrasonic,laser,and microwave modules)were chosen for alternative candidates,to be further tested in a laboratory *** the laboratory tests,the ultrasonic module was selected as a potential approach and the performance was improved by increasing the number of modules and their ***,the improved grain flow sensor was evaluated during field harvesting *** tests with the improved grain flow sensor showed a good potential for rice(R^(2)=0.85,RMSE=126.14 g/s),soybean(R^(2)=0.78,RMSE=43.87 g/s),and barley(R^(2)=0.83,RMSE=37.39 g/s).Further research would be necessary for improvement and commercialization,through various signal processing and field tests under different field and crop conditions.
