基于全栈信创架构的水利部数字孪生平台建设研究与应用实践OA

To address the prominent challenges posed by the water conservancy sector's partial reliance on foreign software and hardware,the stringent requirements of digital twin water conservancy systems for real-time multi-source data fusion and high-fidelity simulation,and the difficulty of ensuring the secure and compliant use of high-precision geospatial data,this study proposed the construction solution of the Ministry of Water Resources digital twin platform,using a full-stack information technology application innovation(ITAI)architecture.Key technologies were adopted,including full-stack domestic substitution of software and hardware,integrated stream-batch processing of multi-source heterogeneous data,coupled computation of water conservancy domain-specific models,integrated two-and three-dimensional digital mapping,and the deep integration of geospatial data confidentiality processing with domestic cryptographic technologies.End-to-end domestic substitution was achieved across the entire technology chain,spanning the central processing unit(CPU),graphics processing unit(GPU),operating system,database,middleware,and geographic information system(GIS)platform.The results showed that the full-stack ITAI architecture met the operational requirements of digital twin water conservancy for real-time responsiveness,high fidelity,and robust coordination,providing practical guidance for the domestic substitution of information systems in water conservancy and related sectors.Nevertheless,limitations remain,including the inadequate large-scale rendering performance of domestic GPUs,limited memory available to trusted execution environment(TEE)containers based on domestic chips,and the high computational overhead of homomorphic encryption.These issues require continued optimization and refinement according to specific application scenarios.
