Study Of High-Tech Factory Digital Twin Virtual Simulation Model Based On Inherently Safer Design Strategy

For Taiwan’s semiconductor industry supply chain, the upstream is IP design and IC design industry, the midstream is IC manufacturing, wafer manufacturing, related production process testing equipment, photolithography, chemicals and other industries, and the downstream is IC packaging testing and related production process testing. Taiwan’s IC manufacturing sector, the epidemic has not slowed down. In order to avoid chain disconnection and market share, downstream manufacturers have successively increased inventories and even urgent orders, making Taiwan’s foundry industry still perform well in the second half of 2021. This research first conceives the control system requirements, and uses PLC to build the system, then uses MATLAB to build the corresponding simulation model, and uses the configuration software to design the important safety human-machine interface to complete the communication function between the human-machine interfaces based on two models. Two models are studied for testing. Under the same input conditions, the physical model and the simulation model can achieve the same input and output conditions, and the possibility of using the simulation model for the electrical control safety design of ISD of new recruits in high-tech factories is verified. This is an important contribution to this research.
