Abstract
The present application provides a digital twin utility tunnel system based on a reduced-order simulation model and a real-time calibration algorithm. The system includes a big data aggregation unit and a real-time simulation deduction unit. The big data aggregation unit is configured to collect static attribute data and real-time dynamic data. The real-time dynamic data includes fixed monitoring data and mobile monitoring data. The fixed monitoring data is collected by gas sensors fixedly installed in the utility tunnel, and the mobile monitoring data is collected by mobile sensors in the utility tunnel. The real-time simulation deduction unit includes a forward prediction module and an inversion calibration module. The forward prediction module is configured to perform dimension reduction simplification and rapid prediction, and the inversion calibration module is configured to perform real-time calibration on a predicted physical field, correct the predicted physical field, and perform inversion on hazard sources.
