[0002] With the rapid development of IoT technology, traditional teaching methods and platforms have obvious deficiencies in practicality and interactivity. Existing teaching systems usually only provide simple 2D interfaces or limited 3D model libraries, lack highly realistic virtual environments and physical simulation functions, and limit students' understanding and operation capabilities of complex scenarios. At the same time, these platforms support a single type of device and limited programming languages ​​in IoT device simulation and programming, and cannot fully cover the diversity and complexity of the IoT field, causing students to encounter difficulties in actual projects. In addition, the lack of data analysis and visualization functions makes it difficult for students to extract valuable information from large amounts of data, affecting their learning effects and the cultivation of data analysis capabilities. Therefore, we propose an experiential 3D IoT teaching system. Summary of the invention
