The purpose of this project is to build a comprehensive intelligent building service platform and intelligent park 3D visualization platform to improve the efficiency, safety and convenience of base park management. This project includes two platforms: service platform and intelligent park 3D visualization platform. The service platform is responsible for project implementation and customization services, data collection, sorting, production and system implementation debugging. The 3D visualization platform of the intelligent park is responsible for scene simulation modeling, data docking platform authorization and other functions. The innovation of this project lies in the highly simulated 3D visualization scene, powerful data integration capability and flexible model library management. The design difficulty lies in data acquisition and collation, three-dimensional scene simulation modeling and system stability and reliability. The design idea is to cooperate with the developers of each subsystem to achieve efficient data collection and collation; use 3D modeling technology and map database, combined with the actual scene for detailed 3D modeling; use B/S architecture to support remote access and cluster deployment; design a user-friendly interface to support multi-terminal control capabilities. Through the implementation of this project, the base park will have a fully functional and easy-to-operate intelligent management platform to achieve efficient, convenient and safe park management.
