Abstract

The present invention discloses a digital twin model of a process manufacturing workshop and a method for constructing a digital twin system. The digital twin model construction method includes: modeling the geometric physical properties of each element of the process manufacturing physical workshop through industrial modeling software to construct a static physical model SPM; constructing a dynamic data relationship model DDRM based on the correlation between the dynamic data of the process manufacturing physical workshop; establishing a data communication interface, and performing model fusion between the SPM and the DDRM to complete the construction of the digital twin model. Furthermore, the multidimensional digital twin models of the workshop elements are graded according to the composition structure of the physical workshop to obtain a workshop-level multidimensional digital twin model; constructing a digital twin system composed of a physical production line system PS, a virtual production line system VS, a production line information service system IS, and a twin data system DS; and performing two-by-two interaction and iterative operation of PS, VS, and IS through DS to complete the construction of the digital twin system.
