| | Number | Name | Function | Composition |
| | 1 | Data support layer | Because the construction of a digital twins podium needs the interaction and IoT perception between real and virtual space, the data layer is built and all kinds of sensors and technical equipment are used to collect information and realize the accurate mapping between the two spaces. This can achieve a comprehensive, three-dimensional, and profound collection of classroom situations. | High-performance sensor data acquisition, high-speed data transmission, life cycle online teaching data management |
| | 2 | Modeling computation simulation layer | It is mainly used in simulation experiments. The establishment of the virtual model involves all-around compound modeling, that is, it is necessary to model the teaching process in real space from different fields and basic principles. The focus of this process is data analysis, which is the perfect combination of virtual and reality. | Modeling algorithm, integrated computing platform, virtual simulation technology platform |
| | 3 | Functional layer | First, reality and the online teaching process need to be the same in all aspects, and can accurately and dynamically simulate the real process. Second, the simulation results of a large number of models need to be comprehensively summarized and integrated, which is also the main advantage of the digital twins system. The third is to use a series of data visualization transformations to map the real operation scene to the online virtual space in a multidimensional and dynamic way, simulating the actual (e.g. smart logistics scene) and virtual interaction. | Virtual teaching space and its mapped real teaching space, multiscale and integrated description of students’ learning state and environment, realizing the dynamic, visual and realistic operation scene of students’ online learning state and environment | | 4 | Immersive experience layer | First, teachers use big data visualization, AI (artificial intelligence), and intelligent cloud systems to present the full picture of the actual teaching space in detail. Second, students can immerse themselves in the process of students’ learning and development based on the intelligent cloud system through remote cooperation. Third, teachers use detailed data modeling, simulation, visualization, and other technologies to realize highly expressive operation scenes, and present virtual learning places in an all-round way without boundaries through augmented reality technology; the learning environment is based on real technology and remote control, which makes students highly interactive. Combined with the “big data + AI” platform and analysis software, the mapping and mirroring of real application scenes are digitally controlled in the virtual learning space, the digital and seamless communication and interaction between teachers and students are felt, and their virtual control virtual reality and practicality are used to achieve the goal of innovative learning and educational activities based on digital twins platform. | User interface |
