Monitoramento e comando de sistemas ciber-físicos industriais com digital twin e realidade aumentada

Abstract

The Digital Twin (DT) is a virtual model that replicates a physical process in real time, allowing the simulation of various conditions and performance analysis. Augmented Reality (AR) is a technology that superimposes digital information on the physical world, enabling a richer and more intuitive interaction between the user and the environment. By integrating these technologies for monitoring industrial systems, AR enhances the visual capabilities, allowing a more detailed and immersive visualization of the system, promoting improvements in problem identification and decision making, parallel to this, the DT allows a better understanding and control of the system. With this, this dissertation aimed to present the experimental implementation of the integration of DT and AR technologies, aiming at the development of a human-machine interface (HMI) for remote monitoring of industrial cyber-physical systems, analyzing the advantages of this integration to enhance the monitoring capabilities of an operator. For this, the game development engine Unity 3D was used for the development of the interface; and the software Blender 3D for modeling and animating the virtual models of the process. For communication, Node-red and the Firebase database were used. At the end of the project, the results and possible advances achieved were analyzed, concluding and observing the real possibility of performing remote monitoring of industrial systems through an interface with AR-based DT applied to Androids smartphones. With the flexibility to be accessed at any time and place, being projected on surfaces by means of a QR Code, with the possibility of modifying the scale and rotate to obtain several observation angles of the supervised process. The results showed superior performance of 14.5 FPS and 82 ms latency, highlighting that the AR gamification resources such as floating popups for data visualization, virtual buttons for sending commands and interactive point for touching the virtual model proved promising and applicable in the task of monitoring industrial cyber-physical systems.
