主 题：GNSS auto-steering system in-field coordination operation farm machinery method simulation
摘 要：Multi-operation within a field and multi-machinery within a machinery operation are common in the scene of scaled farm machinery service,especially with soaring usage of automated steering system in small and medium machinery *** object of this study was to explore a precise and efficient in-field coordination method to realize flow-shop scheduling for farm machinery fleet equipped with RTK-GNSS based auto-steering *** new method is based on three-dimensional coordinate system(XYZ),within which the concept of field,operation strip,and operation task were *** this concept framework,the operation strip state was further defined and its updating algorithm was designed,which can be used for optimization simulations and *** evaluate the method,the waiting time between simulation and a real-world case was compared,and one cloud based prototype system was developed to demonstrate the practicability in the field by using NX200+automated steering *** simulations showed that the in-field coordination can shorten the waiting time between two adjacent *** waiting time between rotary hoeing and seeding can be shortened from 4 h to 6.3 *** field experiment showed that the prototype system could keep good consistency of ridges for a fleet by sharing the guidance line.
