数字孪生滦河工程"四预"平台建设研究OA

In response to the frequent occurrence of historical flood disasters in the Luanhe River,and aiming to enhance its flood defense capability,the construction of the"four pres"platform for the digital twin Luanhe River Project is proposed.Considering the flood characteristics of the Luanhe River Basin,and based on advanced technologies such as digital twin,digital mapping,big data,cloud computing,and the Internet of Things,the platform aims to improve the"four pres"capacity of flood control in the basin.The platform includes three main components:information infrastructure,digital twin platform,and business system.It utilizes a three-dimensional digital twin scenarios as the data foundation and employs a hydrological calculation model as the computing power.The platform facilitates the development of the"four pres"platform and an intelligent"four pres"screen for the Luanhe River,enabling function progressive display across three different time dimensions:historical evolution,real-time monitoring,and trend analysis.By establishing an integrated monitoring system for basin floods in the sky,space and ground,and sharing supplementary data,such as the underlying surface of the river basin,digital terrain,and socio-economic factors,a digital twin scenario for flood control in the river basin is created.It conducts advanced simulation and rehearsal to achieve functions like flood forecasting,early warning,and pre-planning.Upon completion,the platform validates the hydrological monitoring and project dispatching data of the historical"713"flood in the Luanhe River Basin.The calculation results are verified to be reliable,thus it can provide robust support for flood control safety of the Luanhe River Basin.
