Abstract:The application of digital twin technology is an important approach to promote the high-quality development of Taochengpu Irrigation District. Based on the actual situation of the district, this paper preliminarily discusses the application of digital twin technology. Through the construction of a three-dimensional perception system, digital twin platform, business application platform, network security system, and operation maintenance system, it achieves full coverage of water volume metering in the main canal system, integration of all monitoring elements, full connectivity of main canal gate control, stable and secure monitoring information communication, timely and practical water supply perception and prediction, as well as scientific and efficient water resource allocation and scheduling. This empowers water resources management in the irrigation district and facilitates its high-quality development.
