摘　　要：联合收获机是现代农业中必不可少的机械设备之一,在农业生产中完成收割、清理等任务,极大地提高了农业生产的效率。自动导航系统作为现代农业智能化的核心技术之一,可以减少对人工操作的依赖,提高联合收获机的安全性,同时还可以通过实时定位和导航为农户提供更准确的数据和信息,帮助其更好地管理和规划农田。为此,设计了一种基于北斗卫星定位的联合收获机自主导航系统并进行了试验,结果表明:系统能够有效地实现联合收获机的自主导航和定位,且具有较高的准确性和稳定性,为实现智能农业提供了一种有效的技术手段。Combined harvester is one of the essential machinery and equipment in modern agriculture,which completes harvesting and cleaning tasks in agricultural production and greatly improves the efficiency of agricultural production.Among them,the automatic navigation system,as one of the core technologies of modern agricultural intelligence,can reduce the reliance on manual operation and improve the safety of combined harvesters,while the automatic navigation system can provide real-time positioning and navigation for farmers with more accurate data and information to help them better manage and plan their farmland.This paper presents the design and testing of an autonomous navigation system for combine harvesters based on Beidou satellite positioning.The system consists of Beidou satellite positioning system,inertial navigation system and visual navigation system to achieve autonomous navigation and positioning of the combine harvester during field operation.In the experiments,we applied the system to actual farming operations,including tasks such as wheat and corn harvesting and cleaning.The experimental results show that the system can effectively realize the autonomous navigation and positioning of the combine harvester with high accuracy and stability,providing an effective technical means to realize intelligent agriculture.
