In the field of “new infrastructure” intelligent management and control, the Internet of Things and 3D visualization of these two technologies are developing more and more rapidly, and complement each other, which has also aroused the keen attention of road maintenance base managers. This paper will take a road maintenance base as the research object, to explore the practical application of Internet of Things 3D visualization technology in this particular scene. According to the needs of the whole project, through real-time monitoring and data collection of each business data in the intelligent road maintenance base, we analyze the different operational efficiency, energy consumption and output analysis under the traditional mode and the new mode of applying IoT 3D visualization technology, so as to provide a new solution for the intelligent operation and control of the road maintenance base in the future by using IoT 3D visualization technology.
