Combining visualization with GIS, particle simulation, virtual reality, edge calculation and other technologies, the digital pairing of water conservancy projects in Minjiang River Basin is realized, so as to realize real-time monitoring of dams, dikes, spillways, sluices, channels, aqueducts, rafts, fishways, hydropower stations, water quality, environment, water level and rainfall, and realize the sustainable utilization of water resources.
Pass through Hajto wave, hydropower station, ecological fishway, flood gate, etc. Digitally combined, virtual and reality are opened on the cloud. Integrate different data collected by sensors (such as biological information, meteorological information, water level and head information, time-consuming gate opening and closing, flood gate opening, etc.) in the business system. ), and then realize data docking through the interface. The virtual model can be used for operation simulation and performance research, and the research results can be used to improve the operation efficiency of hydropower stations.
Hydropower projects will affect the upstream and downstream aquatic ecosystems, so artificial propagation and release (such as proliferation stations) and fish crossing facilities (engineering compensation measures, such as fishways, etc. ), nature reserves or other remedial measures to maintain ecological balance. Through the visual fishway module built by Hightopo, the appearance, structure, fish species and migration routes of fishway are clearly displayed, so that people can understand the structure and operation principle of fishway.

The reservoir of spillway sluice hydropower station can play the role of flood detention and water storage. The spillway of the reservoir is equipped with a gate, and the flow can be adjusted by changing the opening of the gate. Because of the gate control, the flood control limit water level can be higher than the spillway crest, and the gate opening can be adjusted at any time during flood discharge to control the discharge flow and achieve the purpose of flood detention. Part of the flood stored in the reservoir can play a planned role in the dry season.
Through the case of smart water conservancy and hydropower project, the real-time opening and closing status of multiple flood gates in the dam body can be viewed intuitively, supplemented by the display of meteorological information and water level information data, which helps the personnel of centralized control center to make timely decisions in flood season.
Large hydropower stations have the characteristics of large installed capacity, which affects the regional power supply. Once the reservoirs, dams (including auxiliary dams), power plants and aqueducts in the station fail, it will cause large-scale power failure and seriously affect social harmony and stability. The intelligent security system of hydropower station is associated with the monitoring signal source in the station, displaying the scene monitoring picture, monitoring area intrusion, fireworks, faults, etc. To ensure the good operation of the facilities and equipment in the station. Click the icon in the 3D scene to view the corresponding monitoring screen, personnel name, alarm time and alarm details.
Integrating GIS innovation into it will give visualization more powerful geographical wisdom. Support access to multi-source heterogeneous data, mark the location information of each hydropower station, and instantly restore the high-precision real site. Collecting DOM and DEM data in the basin, and based on the real urban river status information and surrounding scenery information, carrying out three-dimensional geometric modeling on the three-dimensional spatial data of the river channel and river bottom; Then, the finely modeled hydropower station model is superimposed and optimized. Finally, Hightopo rendering techniques such as display list, texture priority and LOD are adopted to realize real-time and realistic virtual scene display of three-dimensional rivers, providing rich means of human-computer interaction.
The particle effect of force field simulates the river flow, and combines different particle colors corresponding to different speed intervals to render the flow field and display the speed data in real time.
The application scope of simulation analysis technology covers many aspects of society. Combined with Web visualization engine, it has promoted the development of engineering simulation, weather forecast, life science, scientific research and education, power system, transportation, industrial manufacturing and other different fields, and injected new impetus into the development of different industries.
Hydropower, shipping, aquaculture, irrigation, flood control and tourism constitute a comprehensive utilization system of water resources to maximize the use of water resources. In the future, the automation and telecontrol of hydropower stations will be further improved and popularized; The development of long-distance, ultra-high voltage, superconducting materials and other transmission technologies will help to speed up the development of rich hydraulic resources in western China.
