Study of Ecosystem Construction and Application in Smart Workshop Based on Digital Twin--Case Study of Cut Tobacco Manufacturing Workshop of Kunming Cigarette Factory

为了实现昆明卷烟厂现有生产过程及管理模式的逐步调优,综合运用数字孪生技术、生产过程实时可视化监控技术、运行状态在线分析与评估预测技术以及生产过程仿真技术,建立了制丝车间数字孪生体,并在此基础上构建了智能车间生态系统。为该生态系统建设确立了5项研究目标和6项重要研究内容;实施了从实体车间映射到数字孪生车间的4个步骤;为数字孪生车间构建了生产前设计仿真、生产中工艺仿真、生产后回溯仿真3阶段生产运行仿真,在数字空间对生产过程进行了诊断分析和迭代优化;利用孪生数据反向优化生产,取得了良好的优化效果。上述研究内容已经在昆明卷烟厂制丝车间实施完成,验证了将智能车间生态系统用于优化现有生产流程及管理模式的有效性和可行性。未来,该生态系统将对全国烟草行业数字化管理产生积极的示范意义。

For the gradual optimization on the existing production process and management mode of Kunming Cigarette Factory,by comprehensively utilizing the digital twin technology,the real-time visual monitoring technology of the production process,the online analysis,evaluation and prediction technology of the operating status,and the simulation technology of the production process,the digital twin body for the cut tobacco manufacturing workshop was established,and on the basis of which,the ecosystem in smart workshop was constructed.For the construction of such an ecosystem,5 research targets and 6 important research contents were ascertained;4 steps of mapping from the physical workshop to the digital twin workshop were implemented;for the digital twin workshop,3 stages of production operation simulations consisting of design simulation before production,process simulation during production,and backtracking simulation after production were performed,and the production process was diagnosed,analyzed and iteratively optimized in the digital space;the twin data was used to reversely optimize the production,achieving good optimization results.The above research contents have been implemented in the cut tobacco manufacturing workshop of Kunming Cigarette Factory,which verifies the validity and feasibility of using the ecosystem in the smart workshop to optimize the existing production process and management mode.In the future,such an ecosystem will have a positive demonstration significance for the digital management of the tobacco industry in China.
