数字孪生是实现物理车间与虚拟车间交互融合的有效技术手段，被国内外相关学术界和企业高度关注，但目前的研究尚处于理论研究阶段，研究成果相对较少且缺乏整体解决方案。本文分析传统车间管控系统架构存在的不足，提出基于数字孪生的数字化车间运行新流程。基于B/S架构进行数字孪生系统设计，并给出与业务系统进行数据及接口集成的方法。利用数据采集网关技术，将现场设备数据进行实时采集、分类、清理及上传，实现基于现场实时驱动的虚拟车间运行。从产品、生产线、过程信息3个方面构建基于数字孪生的车间信息模型。最后，基于武昌造船集团有限公司的全自动化直管柔性加工生产线实现了数字孪生车间系统。
Digital twin is an effective technical means to realize the interaction and integration between the physical workshop and the virtual workshop. It is highly concerned by relevant academic circles and enterprises at home and abroad, but the current research is still in the theoretical research stage, and the research results are relatively few and lack the overall solution.The shortcomings of the traditional workshop management system architecture are analyzed, and a new digital logistics operation process based on digital twin is proposed. The digital twinsystem is designed based on the B/S architecture, and the method of integrating data and interface with the business system is given. The data acquisition gateway technology is used to collect, classify, clean and upload the field device data in real time, and realize the virtual workshop operation based on the field real-time driving. The workshop information model based on digital twin is constructed from three aspects:product, production line and process information. Finally, the digital twin workshop system is realized by a fully automated straight tube flexible processing production line based on Wuchang Shipbuilding Industry Group Co., Ltd.
