Abstract:Combining BIM, big data, digital twinning and industrial internet technologies, with Unity 3D as the front-end development platform of 3D visualization, integrating 3D scene, field operation data and virtual plant system, a 3D all-data visualization system is built to meet the needs of remote plant 3D display and synchronous presentation of operation data. By means of effective integration of the 3D design digital model and real-time operation data of the plant, the functions of query, management, training and demonstration are realized by using the 3D scene of the plant.
