摘要
目的 为解决凹版印刷生产过程中监控系统功能单一、可视化程度低、信息利用率低等问题,构建一种基于数字孪生的监控系统四层架构模型。方法 通过SolidWorks、3DSMax、Unity3D三维建模软件搭建凹印机虚拟场景,基于Modbus TCP/IP协议采集设备的实时数据,使用SQL Server数据库对设备数据分类存储,并结合凹印机虚实映射逻辑结构,编写C#脚本实现物理实体与虚拟模型间的同步映射,完成监控系统的开发。结果 该监控平台实现了凹印机的虚实同步运行、状态监控、套准偏差监控和健康管理等功能,为印刷企业智能化运维提供了可行方案。结论 与传统印刷装备监控相比,基于数字孪生的监控系统突破了时间、空间、投入成本等条件的限制,操作者可实时掌握凹印机的生产信息、运行状态、历史信息等,极大地提高了设备稳定生产的效率,降低了企业的成本。
The work aims to construct a four-layer architecture model of monitoring system based on digital twin to solve the problems of single function,low visualization and low information utilization of monitoring systems in gravure printing production.On the visual monitoring platform,a virtual scene of the gravure printing machine was built with SolidWorks,3DS Max and Unity 3D modeling software.The real-time data of the equipment were collected based on the Modbus TCP/IP protocol.The SQL Server database was used to realize classified storage of equipment data,and the virtual-real mapping logical structure of gravure printing machines was combined to write C#scripts to realize the synchronous mapping between the physical entity and the virtual model.Finally,the monitoring system was developed.The platform realized the functions of virtual-real synchronous operation,condition monitoring,register deviation monitoring and health management of gravure printing machines,which provided a feasible scheme for intelligent operation and maintenance of printing enterprises.Compared with the traditional printing equipment monitoring,the monitoring system based on digital twin breaks through the time,space,input cost and other conditions.Operators can grasp the production information,operation status and historical information of gravure printing machines in real time, which greatly improves the efficiency of stable production of equipment and reduces the cost of enterprises.
