Abstract: 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.
