摘要：

为解决目前光纤二次套塑车间智能化、数字化程度低的问题，提出基于数字孪生(digital twin，DT)的光纤二次套塑车间三维可视化监控与故障诊断的方法。面向光纤二次套塑车间设备，结合车间生产工艺和设备运行机理，对光纤二次套塑车间进行全物理属性的数字化建模，构建虚拟孪生场景。通过数据的交互传递实现虚拟车间和物理车间的实时映射，虚实交互可以实现对光纤二次套塑车间设备可视化、智能化操控。通过建立Unity3D与MySQL数据库的连接，对孪生数据进行存储。以某光纤二次套塑车间为应用对象，设计并开发了光纤二次套塑车间数字孪生系统，验证了所提方法的有效性。

Abstract:

In order to solve the problem that the current optical fiber secondary coating workshop has inferior intelligence and low digital degree, a three-dimensional (3D) visual monitoring and fault diagnosis method for the optical fiber secondary coating workshop based on digital twin (DT) is proposed. In view of the equipment in the optical fiber secondary coating workshop, combined with the workshop production process and equipment operation mechanism, the digital modeling of all physical properties of the optical fiber secondary coating workshop is carried out, and the virtual twin scene is constructed. Real-time mapping between the virtual workshop and the physical workshop is realized through the interactive transmission of data, and the virtual-real interaction can realize the visualization and intelligent control of the equipment in the optical fiber secondary coating workshop. By establishing the connection between Unity3D and MySQL database, the twin data are stored. The method is applied in an optical fiber secondary coating workshop. A DT system of the optical fiber secondary coating workshop is designed and developed, and the effectiveness of the proposed method is verified.

Key words: digital twin, optical fiber secondary coating workshop, 3D modeling, visual monitoring, fault diagnosis
