Digital Twin: Uma proposta de geração de ambientes virtuais baseado em comissionamento virtual utilizando motor gráfico Unity3D

Abstract

Digital Twin is a concept that originated in 2010 in aerospace engineering as an accurate and integrated simulation of the flying vehicle system developed by NASA. Since then, this concept has spread to various areas of knowledge, especially in the industrial sector and manufacturing processes strongly linked to Industry 4.0 concepts. Currently, Digital Twin uses techniques and tools applied in systems modeling, machine learning, data analysis, simulation in virtual environments, cyberphysical systems, among others. And for this reason, there is a frequent debate on the definition of Digital Twin, especially on the lack of standardization of the concept and methods needed for virtualization of physical processes. For virtualization of manufacturing processes, we apply in this work the virtual commissioning as a technique to achieve this goal. The virtual commissioning allows to verify the manufacturing system by performing a simulation involving a virtual plant and a real controller. And to generate the virtual plant, we use a graphic game engine as the virtual environment generating tool, enabling simulations, and mirroring a physical controller. In summary, this work proposes a virtualization method based on virtual commissioning of physical processes to develop a Digital Twin. Using graphic engine software to generate a three-dimensional virtual environment as a digital representation. To generate a set of methods and practices to create a digital twin from a legacy manufacturing system.
