The Three Gorges Modern Energy Innovation Demonstration Park is a high-end equipment industrial park integrating wind, light, and storage. The park has rich types of energy sources and complex and diverse large-scale equipment. The old park management model has been difficult to adapt to the business characteristic of park's high-industrial concentration and the coexistence of multiple business forms. The characteristics are mainly reflected in the lack of unified planning and design, the ineffective use of historical data, the low level of informatization and digitalization, the emphasis on production, the neglect of human nature, and the lag of management information. Through research on the integration of BIM, GIS and IoT technologies, the article integrates various BIM data, equipment monitoring data and inspection and maintenance data in the park, eliminates information islands, realizes data sharing across the park, and assists manager in scientific operation and maintenance.
