中文摘要英文摘要

籽棉清理机作为棉花加工的核心设备,在籽棉杂质清理加工过程中,存在设备状态不可视、故障预警被动滞后和运维策略粗放化等问题,制约了棉花加工质量、效率和企业效益的进一步提升.本文引入数字孪生技术,根据籽棉清理机工作原理及结构,构建其数字孪生模型,建立物理空间与虚拟空间的高保真映射机制,利用Unity开发了籽棉清理机数字孪生监测系统,实现了籽棉清理机运行状态的实时监测、故障主动预警以及工艺决策实时优化.对系统性能进行评价,结果表明:数据丢包率为0、CPU使用率为5%、GPU显存平均占用率为4%、运动仿真帧时均值为20.416 ms,验证了该系统具有良好的稳定性、可靠性和鲁棒性.

The seed cotton cleaning machine,as the core of cotton processing,faces operational challenges that limit overall efficiency.These include the inability to monitor equipment status in real time,delayed and passive fault alerts,and loosely defined operation and maintenance strategies during the impurity removal process.Such limitations have constrained further improvements in cotton processing quality,production efficiency,and overall enterprise profitability.To address these issues,digital twin technology was applied to create a virtual replica of the physical seed cotton cleaning machine.Based on a detailed analysis of the machine's operational principles and mechanical structure,a high-fidelity digital twin model was constructed.This model established a dynamic,bidirectional mapping mechanism between the physical machine and its virtual counterpart,enabling seamless data exchange and state synchronization.Using the Unity platform,a comprehensive digital twin monitoring system was developed for the seed cotton cleaning machine.This system integrated real-time data acquisition,simulation,and analysis capabilities.It allowed for real-time monitoring of the machine's operational status,facilitated proactive fault warnings through predictive analytics,and supported dynamic optimization of process decisions based on simulated scenarios.Performance evaluations of the system demonstrated strong stability and reliability with key metrics,including a data packet loss rate of 0,a CPU usage rate of approximately 5%,an average GPU memory occupancy of around 4%,and an average motion simulation frame time of 20.416 ms.The system was verified to possess excellent stability,reliability and robustness.
