"Reservoir Intelligent Housekeeper" is an intelligent management solution that deeply meets the needs of the digital development of the water conservancy industry. It aims to innovate the operation and management mode of reservoirs through cutting-edge technology, build a strong reservoir safety line and improve the efficiency of water resources utilization. The platform is supported by the Internet of Things, big data, artificial intelligence and cloud computing technology, and builds a full-process management system of "data collection-analysis and modeling-intelligent decision-making-precise execution. In the data dimension, it can integrate multi-source information such as reservoir engineering data, real-time hydrological data (water level, rainfall, flow, etc.), historical meteorological data and video monitoring data, and form a standardized data base after cleaning and alignment. At the functional level, four core capabilities have been realized: first, real-time monitoring, uninterrupted collection of key parameters such as water level, seepage flow and water quality through distributed stations, and visual presentation of reservoir operation status combined with video monitoring; Second, intelligent early warning, based on physical model and DLinear time series prediction model (time series is decomposed into trend and remainder series for modeling respectively), accurate prediction of flood, drought and other risks and timely warning; the third is remote dispatching, which supports remote control of pump gate equipment and dynamic allocation of water resources. Fourth, file management, standardized storage and traceability of operation data and maintenance records. The platform adopts a graphical visual interface, which can be customized and expanded according to the needs of reservoirs of different regions and sizes, and has shown significant value in multi-reservoir scenarios, effectively improving the safe operation capability and management refinement level of reservoirs.
