摘要:
数字孪生秦淮河通过高效获取海量流域数据,对物理流域进行网格划分,构建河流、湖泊、水库、水闸等水利对象的关联网络,形成面向业务主题的知识图谱,支撑物理流域到数字镜像空间的映射;依托多模型解耦与耦合技术,实现面向多业务场景的模型灵活组装和网格嵌套计算;通过知识驱动的“四预”智能应用,实现传统的要素预报向影响预报转变,传统的阈值预警向风险预警转变,预演过程的正向推演反向溯源,基于预演形成多个预案并选择最优预案,支撑流域精细管理和精准决策。
Abstract:
The digital twin of the Qinhuai River obtains massive watershed data efficiently, divides the physical watershed into grids, and constructs the associated network of water conservancy objects such as rivers, lakes, reservoirs, and sluices, and forms a business-oriented knowledge map to support physical watersheds to digital mirror space mapping; relying on multi-model decoupling and coupling technology, realize flexible assembly of models and grid nested calculations for multiple business scenarios; through knowledge-driven "Four Pre" intelligent applications, realize the transformation from traditional element forecasting to impact forecasting, the traditional threshold early warning is transformed into a risk early warning. The forward deduction and reverse tracing of the rehearsal process form multiple scenarios based on the rehearsal and select the optimal scenario to support fine management and precise decision-making of the watershed.
