The invention discloses an intelligent water affair digital pipe network information model which comprises an information management module, an adjustment calculation module, an accident analysis module, a hydraulic simulation module, an analysis report module and a result management module. A three-layer architecture of the interaction layer, the service layer and the data layer is adopted, the interaction layer provides an interaction interface for a user, and the service layer provides a function implementation module for the service layer to access the interaction layer of the data layer.According to the invention, the Internet of Things technology and the big data mining technology are combined; pipe network model establishment, pipe network hydraulic adjustment, pipe network accident analysis and energy-saving and consumption-reducing analysis schemes are realized; therefore, informatization management of a pipe network hydraulic model is achieved, a powerful scientific decisionbasis is provided for water supply planning, design, scheduling, first-aid repair and archive management of picture data, a good foundation is laid for optimal scheduling of a pipe network, the working efficiency and quality are greatly improved, and a water company 'smart water affair' process is truly protected.
