摘要
为了解决微组装生产线数字化转型面临的数据处理难和设备信息化控制难的问题,设计了微组装生产线单元数字孪生系统架构,提出一种基于实时生产数据的四维融合模型孪生同步方法,从行为实时映射、状态实时映射和动作实时映射的角度对孪生同步进行了诠释,并对其关键技术——多源异构数据分类、清洗与解析和实时数据驱动四维融合孪生模型进行了详细阐述。设计并开发了原型系统,通过实例验证了所提方法的有效性,为实现微组装生产线数字孪生提供了解决方案。
To solve the difficulties of data processing and equipment information control in the current digital transformation of the micro-assembly production line,a digital twin system architecture of micro-assembly production unit was designed.A twin synchronization method of four-dimensional fusion model based on real-time production data was proposed.The concept of twin synchronization was explained from behavior real-time mapping,state real-time mapping and action real-time mapping.The key implementation technologies for twin synchronization such as multi-source heterogeneous data classification,cleaning and analysis and four-dimensional fusion model driven by real-time production data were elaborated in detail.Meanwhile,the prototype system was designed and developed,and the effectiveness of the proposed method was verified by a practical case study.The result provided a solution for the realization of digital twin in the micro-assembly production line.
