Relying on the self-developed Fulima cloud platform, the independent development and editing of digital content inside the exhibition hall are realized through localized deployment. Through the solid construction of the backend base of the digital center, a solid foundation has been laid for the realization of comprehensive intelligent management and control, making the management and operation of the exhibition hall more efficient and intelligent. (1) The one-key switching of the intelligent control background includes two functional modules: conventional switching and data switching, which can realize the one-click switching of the content, color, lighting and even the entire theme of the digital exhibition hall, as well as the one-click switching of the six major data attributes of the digital center. (2) Based on the control background of the system, in addition to freely changing the digital content of the exhibition, it can also realize independent editing, unified data management and data security encryption of digital content based on the self-developed low-code platform.
