摘　　要：运用数字孪生技术,在对草场环境及牲畜状态进行感知的基础上建立草场放牧监测系统。该系统将虚拟仿真技术Unity3D应用于草场放牧场景的孪生三维模型,为后续监测呈现可视化效果;采用无线传输技术搭建采集网络,实现草场及牲畜信息交互的功能,并选用模糊综合评价方法对草场进行放牧强度划分。为了验证该系统的有效性,以内蒙古锡林郭勒盟锡林浩特市毛登牧场的真实场景为例进行综合试验。结果表明:与传统的放牧监测系统相比,该系统运用数字孪生技术实现了数据共享和物理草场与孪生草场信息的同步,有效解决了传统放牧监测中决策滞后的问题;通过孪生草场能对物理草场的放牧场景进行仿真模拟,不受客观条件限制,能有效预测各种放牧情况,实现草场环境及牲畜放牧状态精准监测,在实际放牧中能及时应对突发情况,提升草场放牧决策的自主性。Using digital twin technology,grazing monitoring system was set up on the basis of sensing pasture environment and livestock status.In this system,the virtual simulation technology Unity3D was applied to the twin three-dimensional model of pasture grazing scene to present the visualization effect for follow-up monitoring.Wireless transmission technology was used to build a collection network to realize the function of information interaction between pasture and livestock,and fuzzy comprehensive evaluation method was used to classify grazing intensity of pasture.In order to verify the effectiveness of the system,the real scene of Maodeng Pasture in Xilinhot City,Xilin Gol League,Inner Mongolia was taken as a testing example.The results showed that compared with the traditional grazing monitoring system,the system used digital twin technology to realize data sharing and synchronization of physical pasture and twin pasture information,and effectively solved the problem of decision-making lag in the traditional grazing monitoring system.Through the twin pasture,the grazing scene of the physical pasture could be simulated,which was not restricted by objective conditions,and could effectively predict various grazing conditions,achieve accurate monitoring of the pasture environment and livestock grazing state,and timely respond to emergencies in actual grazing,improving the autonomy of grazing decision-making of the pasture.
