Abstract:
To deal with the problems such as low information transparency, poor real-time performance and lack of delicacy control in drinking water treatment plant, an integrated operation and maintenance platform architecture was established, and the key technologies based on five-dimension digital twin model was proposed. The heterogeneous data integration technology and multi-level 3D visualization monitoring of digital twin water treatment plant were proposed to solve the problem of visual monitoring. The edge-cloud platform-based strategy was proposed with hybrid decision-making framework with mechanism model and intelligent model to solve cooperative control problem. Based on water production process, the models such as water supply and demand prediction, dosing optimization, pump group optimization, equipment preventive maintenance were established for process simulation and optimization. An integrated platform for drinking water treatment plant was developed, which verified the effectiveness of the proposed model and provided a certain reference for the realization of digital twin-based drinking water treatment plant.
