Structural Design of Digital Twin Laboratory Model Based on Instruments Sharing Platform

Aiming at the proposals of the inability to actively predict the faults of instruments, the inconvenience of daily maintenance and so on, this paper applies the digital twin technology to the instruments sharing laboratory, designs and constructs the Digital Twin Laboratory Model (DTLM) based on the instruments sharing platform, which includes physical laboratory, virtual laboratory, Laboratory Digital Twin Data (LDTD) and Laboratory Service Platform (LSP). It designs the digital twin laboratory operation mechanism, workflow and implementation plan in detail. The proposal can analyze the extracted laboratory digital twin data and predict the possible risks effectively, so as to predict, maintain and improve the real system under the condition of ensuring the normal operation of the laboratory physical platform. Through the analysis, the DTLM can predict the laboratory operation fault with high accuracy, effectively improve the stability of the laboratory operation and reduce the overall maintenance cost of the laboratory.
