摘要：
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. © 2021, Editorial Department of CIMS. All right reserved.
