This article studies the visual management of college assets under the changing environment of the Internet of Things, uses virtual reality technology to discuss the mechanism of its visualization, and studies the technical selection from the aspects of system architecture, database, and message middleware to provide reliable colleges and universities asset management, provide a complete authority distribution management mechanism, have a safe and reliable data storage mechanism and good scalability. And according to this goal, the overall architecture of the system is designed. Under this architecture, the main modules of the college asset management system divided into college asset information management, information release management, and other modules. To meet these functional modules, related diagrams are designed. The diagram creates a data table corresponding to it. The emphasis is on the systematic analysis of system performance and uses case modeling, static model, and dynamic model based on UML. The overall design of a three-tier logical structure including presentation layer, business logic layer, and data access layer, six functional modules including business process management, platform visualization management, application management, data storage, data processing, and data asset security control. Using the MySQL database and the database design method based on the E-R model, the definition of data entities was completed and the table structure design was carried out. It proved that the functions of the platform are in line with actual needs, and the performance can also meet the business requirements of the visualized management of college assets. It can manage data assets well and has high practical application value.
