摘　　要：针对牛粪好氧发酵过程中交互性差和依赖经验决策的问题,课题组设计了基于数字孪生的发酵过程监控系统。首先,通过Unity引擎构建了发酵仓数字孪生虚拟模型,并设计搭建了场景环境和虚拟界面;其次,设计了物联网(internet of things, IoT)网关以及数据库用于传输和存储孪生数据;最后,通过搭建模拟平台对数字孪生系统进行了时序同步和碰撞检测实验。实验结果表明:设计的发酵仓数字孪生监控系统虚拟模型与实物同步性较高,能做到虚实同步,验证了系统的可行性。To address the problems of poor interactivity and reliance on experience in decision-making during the aerobic fermentation process of cow dung,a fermentation process monitoring system based on digital twin technology was designed.Firstly,a digital twin virtual model of the fermentation chamber was constructed using the Unity engine,and the scene environment and virtual interface were designed and built.Secondly,the IoT gateway and database were designed for transmitting and storing twin data.Finally,a simulation platform was built to conduct time-series synchronization and collision detection experiments on the digital twin system.The experimental results show that the designed digital twin monitoring system virtual model of the fermentation silo has high synchronization with the physical object,which can achievethe virtual and real synchronization,and verifies the feasibility of the system.
