Build a smart park platform based on the AsiaInfo digital twin platform(AISWare Digital Gemini). By connecting with the existing subsystems, data fusion and system linkage can be realized, and the AsiaInfo digital twin platform can provide capabilities such as comprehensive situation, smart operation, smart assets, and smart security.Digital twin technology can realize the global visualization of park space information, fine insight into real-time situation, deep mining of park operation rules, and deduction and simulation of park development trends.
