摘　　要：针对果园种植管理系统存在可视性低、实时性差、适应性弱和交互方式单一的问题,提出一种面向种植管理过程的果园数字孪生系统六维模型。从管理要素实体建模、管理过程动态建模、管理系统仿真建模和管理策略优化建模4个方面论述了系统模型构建理论与技术体系。以六维模型为基础,理论与技术体系为支撑,设计了基于数字孪生的果园虚拟交互系统架构,并对系统开发过程的关键技术进行了阐述。借助Unity3D仿真平台搭建了果园虚拟交互系统,实现对果园的三维可视化监测。实验结果表明:该系统在农业物联网平台数据共享基础上,通过数据驱动、三维展示、人机交互、重构事件和智能决策方面提升了果园种植管理系统监测能力,为建设智慧果园提供参考。Aiming at the low visibility,poor real-time,weak adaptability and single interaction mode in orchard planting management system,a six-dimensional model of orchard digital twin system for planting management process is proposed.The system model construction theory and technology system is discussed from four aspects,entity modeling of management elements,dynamic modeling of management process,simulation modeling of management system and optimization modeling of management strategy.Based on the six-dimensional model,supported by the theory and technology system,the virtual interactive system architecture of the orchard based on the digital twin is designed,and the key technologies of the system development process are standard.With the Unity3D simulation platform,the orchard virtual interactive system is built to realize the three-dimensional visualization monitoring of the orchard.The experimental results show that the system improves the monitoring ability of orchard plantation management system through data-driven,3D display,human-computer interaction,reconstructed events and intelligent decision-making on the basis of data sharing on the platform of internet of things in agriculture,which provides a reference for the construction of smart orchard.
