摘要
En 中文
The new generation of intelligent manufacturing systems requires a deep integration of human-cyber-physical spaces. Visual analytics plays a critical role in effectively navigating humans through twin data, enabling them to make better decisions and discover new knowledge, contributing to the evolution of digital twins. However, due to the lack of study of visual analytics components and their inter-relations in the context of the digital twin, the visual analytic process of digital twin systems lacks guidance to fully integrate human domain experience and cognitive abilities into the intelligent decision-making process of digital twin systems. Therefore, this paper proposes a conceptual visual analytics framework for digital twins (DTVA). Moreover, from the perspective of data and models in digital twins, the works concerning key factors of visual analytics, including digital-twin visual representation (DTV), analytical reasoning (DTA), and human-machine interface (DTI), are analyzed from data flow, task flow, and visual flow. At last, a case study of DTVA-based anomaly detection, which focuses on the abnormality detection of crane operation status, is presented. This work can support digital twin visual analytics, put forward ideas for the direction of visual analytics, and provide a promising direction for digital twin visualization services.
