Abstract: This paper introduces the concept of digital twins into the field of laboratory management,
taking the twin-screw extrusion experimental device as an example, developed a digital twin management
system for experimental devices. Starting from the informatization transformation of traditional equipment, the
development process of the digital twin management system is introduced from the aspects of on-site data
network transmission, laboratory network redundancy configuration, data management, and application
management system development. The advantages of the digital twin management system are elaborated
from the aspects of experimental safety, operation and maintenance costs, and experimental efficiency. The
content covered in this article has certain guiding significance for the application of digital twin technology
in laboratory management in colleges and universities and the informatization upgrade of equipment in small
and medium-sized enterprises.
