Dynamic monitoring of anti-seepage wall grouting, real-time supervision of workers' work ......On December 13, the reporter saw in the project department of the first phase of the key embankment reinforcement project in the Dongting Lake District in Heshan District, Yiyang City, that the smart platform of the construction site was connected to the digital twin Dongting Lake system, and the project construction situation can be seen at a glance by opening the platform on the computer or mobile phone.
This year, our province has vigorously promoted the construction of digital twin Dongting Lake and installed a "smart brain" for Dongting Lake. The on-site supervision of the projects under construction and the shoreline of rivers and lakes in Dongting Lake are carried out, and the typical floods and flood storage are simulated and deduced, so as to provide efficient support for flood control and drought control, project scheduling and comprehensive management of Dongting Lake, and promote the intelligent and modern development of Dongting Lake protection and governance.

Eight Hundred Miles of Dongting".
Embankments, embankments, pumping stations, dangerous sections, water conservancy scenic spots, ......On December 13, the staff of the Provincial Dongting Lake Water Conservancy Affairs Center opened the digital twin Dongting Lake system, and the river and lake water system, water conservancy facilities, and key water conservancy projects of Dongting Lake were unobstructed.
"Smart brains" need to be supported by data backplanes. Our province has collected and sorted out the historical data of the Dongting Lake area for many years, collected geospatial data, and completed the underwater topographic survey of about 2,700 square kilometers of lake basins and rivers in the four river systems and realized digitization. Collect and summarize information on elements such as underwater topography, water conservancy facility surveying and mapping, satellite remote sensing data, basic data of watershed objects, business management data, and real-time monitoring data, and consolidate the data baseboard.
The digital twin Dongting Lake system has built a model of Dongting Lake scouring and silting, a remote sensing model of Dongting Lake water surface change, a topography model of Dongting Lake basin, a flood storage model of important flood storage and detention areas, and an evolution model of flood storage and flood storage at flood gates, etc., to digitize important contents such as the typical annual flood of Dongting Lake, the emergency transfer plan for flood storage and flood storage, the drainage and dispatching plan for key flood-prone areas, and the Dongting Lake water conservancy work manual. "Eight Hundred Miles of Dongting" is a map, and all information can be found according to the map.
With the support of the data baseboard, on the Dongting Lake Smart Water Conservancy Comprehensive Display Platform, functional modules such as lake area overview, rain and drought conditions, engineering system, and river and lake management are developed to realize data sharing such as hydrology, water resources, and river and lake management.

The management of water conservancy projects and the prevention of flood and drought disasters are more "smart".
The Jiangbei urban area of Changde City was hit by heavy rain, and the water level of the 'four rivers and one lake' in the Jiangbei urban area rose sharply. "In July this year, a flood control simulation drill was carried out at the intelligent pumping station in Jiangbei District, Changde City.
The dispatcher clicks on the intelligent platform of the pumping station, and all kinds of data are quickly uploaded to the background, and the AI technology automatically warns through model deduction, and compares and presents the water level change in an anime way, and the intelligent scheduling is automatically turned on after 30 seconds.
The "tentacles" of the digital twin system have penetrated into all aspects of the Dongting Lake area, and the "wisdom" of Dongting Lake governance has flashed.
Vigorously promote the construction of smart pumping stations. At present, the unified monitoring system of large and medium-sized pumping stations in Dongting Lake District has been included in the key tasks of flood drainage capacity building in the "14th Five-Year Plan", and after improving the IoT sensing and information transmission modules, it can monitor 313 large and medium-sized pumps in Dongting Lake District in real time, and upgrade data collection, intelligent scheduling, remote control and other functions.
Empower the construction and management of water conservancy projects. Real-time monitoring of major water conservancy projects in the Dongting Lake area, key data, early warning, on-site pictures, overall progress and other information can be presented one by one with just a click of the mouse.
Flood and drought disaster prevention will be more scientific
The digital twin Dongting Lake system monitors the water level and flow of more than 40 hydrological control stations in the Yangtze River and Dongting Lake area, and can realize point-to-point scheduling
Through the analysis and judgment of rain, water and drought conditions through the digital intelligent system, it provides scientific support for the "four predictions" function of flood and drought disaster prevention in Dongting Lake area
Typical floods, flood storage and storage were simulated and deduced, typical historical flood scenarios were constructed, and 49 weak links of embankments in the lake area were reminded in a targeted manner, so that the defense was realized from the original "blind box" to realize early perception.
