Featured Guofeng digital twin smart dam 3D visualization

Foreword

Water conservancy is prosperous, and the grain is abundant. As an important part of the stability and harmony of the national economy, water conservancy not only has comprehensive applications such as flood control and disaster reduction, agricultural irrigation, urban water supply, fishery and foreign trade, tourism and shipping, and ecological environment. Hydropower resources are also one of the most important sustainable energy sources. Dams, reservoirs, hydropower stations and other water conservancy hubs complement each other and stabilize urban development. With the development of informatization, the application of smart hydropower stations and smart dams in the form of emerging technologies such as the Internet of Things, 5G, and big data have also provided greater value to the traditional water conservancy industry, enhancing the overall perception of the industry, sharing integration, and wisdom. management.

Today, we will use Hightopo's HT products to build a 3D visualization scene of an ink-and-wash landscape dam. Through three-dimensional modeling, the operation status of key management objects such as the main dam, factory building, ship lock, ship lift, generator set, and water discharge structure can be visually displayed from multiple angles, and the comprehensive operation status of water conservancy management can be grasped on one screen.

effect display

Different from the previous digital twin works in sci-fi style, this dam visualization project adopts the poetic and painting style of ink painting and classical music, and presents serious and boring engineering projects through traditional ink paintings with profound artistic conception, allowing users to remember and impress. profound.

The initial loading of the page accompanied by the sound of rain, Yan Ming, painted a dam of ink-and-wash with a staggered landscape.

system analysis

The HT 3D visualization technology adopts the B/S architecture. After the model is lightweight, users no longer need to spend high prices to purchase high-performance graphics workstations to support the 3D visualization system. Users can access the 3D visualization system anytime and anywhere through a PC, PAD or smart phone as long as they open a browser to realize remote monitoring and control. It supports multiple control devices such as VR, handheld or fixed touch terminals, and easily centralizes the control of the displayed content, and realizes the functions of visual object browsing, tapping, filtering, circle selection, map panning and zooming.

Roaming inspection

A 360-degree panoramic view of the dam through the HT three-dimensional engine, the virtual inspection and roaming of the entire water conservancy equipment from the flying perspective of the crane in the scene.

Safety monitoring data visualization

Dam safety monitoring is mainly divided into seepage, internal, environmental volume and deformation monitoring. Monitoring instruments mainly include displacement gauges, osmometers, stress gauges, etc. Monitoring data is divided into: non-directional scalar information; including upstream and downstream, left and right banks, and vector information in the vertical direction of the dam.

Monitoring indicators mainly include deformation, stress, seepage flow, etc. Among them, the dam safety factor can be determined according to the hydraulic building manual, and the stress warning value can be drawn; combined with the typical dam seepage analysis results, the seepage flow monitoring and warning value can be drawn up.

Deep integration of video surveillance data

HT is a component library based on the HTML5 standard, which can seamlessly integrate various multimedia functions of HTML5 and support the integration of various video resources to form a unified video access platform. It can mark camera objects on a two-dimensional and three-dimensional situation map and associate its video signal source. The corresponding surveillance video can be retrieved by interacting in the scene.

regime monitoring visualization

Support the integration of various monitoring system data, based on Geographic Information System (Geographic Information System, GIS), visually display the distribution, coverage area, type and monitoring information of self-built, flood reporting and sharing water and rain forecast stations and other elements, combined with professional analysis and prediction Model, multi-dimensional analysis of water regime parameters such as flow rate, flow velocity, rainfall (snow), evaporation, sediment, ice, moisture, water quality, etc., visualized early warning and warning of abnormal water regimes, assisted users to grasp water regime dynamics in time, and improve Corresponding efficiency of water hazard emergency response.

Scene interactive switching

By dragging the flood interception control panel on the left side of the scene, the opening of the gate can be controlled to achieve the effect of changing the flow rate of the gate in the scene.

By clicking on the hydraulic building, you can switch the angle of view to different equipment of the dam, and display the dam scene more intuitively and concretely.

The background music can be controlled by clicking the swallow. In the default playing state, the swallow is dancing at the top of the panel. Click to pause the background music, and the swallow will also pause.

Value reflects

Dam safety monitoring is very important. Through HT visualization, operation and maintenance managers can intuitively and concretely obtain first-hand data, analyze the operation status of the dam and bedrock, grasp the working form of the dam, evaluate the safety status of the dam, and discover the dam Provide evidence for abnormal signs. The HT visualization of Tupu software can help users locate monitoring equipment clearly and quickly, and obtain basic monitoring information of relevant measuring points in time.

BIM modeling and model lightweight

The main basis of 3D dam solid modeling is the dam design drawings. Because the application of the 3D visualization display of dam monitoring information does not have high requirements for dam structure modeling, and considering that the BIM model file is generally large, it is not conducive to running directly in the browser. Hightopo's 3D visualization is adopted by designers to adopt lightweight For the scene built by modeling, the model effect is mainly presented with textures, combined with the powerful rendering capabilities of the HT engine, to ensure the efficient and smooth loading and running of the scene on the Web and to ensure the excellent visualization of the scene.

In addition, point cloud data can be used to obtain detailed geographical environment information of the dam and its surroundings, and to improve the missing parts of the model to improve the accuracy of the model.

If there is a need for BIM models, HT provides the function of converting BIM models to HT primitives, which can perform lightweight processing on BIM files to ensure the smoothness of their loading.

HT and GIS

GIS provides more information about terrain, buildings, facilities, etc. by superimposing and fusing multi-source data such as oblique photography data, vector data, 3D model data, and BIM data. GIS can organically combine the spatial location of objects in the real world with related attributes, thereby providing technical support for spatial decision-making and realizing visual expression. HT provides GIS integration and other related services to realize the three-dimensional display of dam terrain scene data, and further assist the visualization process of water conservancy dam projects.

summary

Through the promotion and application of HT three-dimensional visualization and information technology in water conservancy, power, energy and other fields, it will bring great convenience to industry operation and maintenance management. Digital twin technology will help optimize management processes, improve management quality, and create vivid images. Display data.

Tupu software visualization empowers water conservancy power generation visualization, smart power station visualization, smart photovoltaic visualization and other industries that are more adapted to the development of the times. As shown in the figure below, in power, energy and other related industries, it is also based on Tupu Software’s years of project experience accumulation and solid visual technical support, and efficient customized design and development according to business needs, to contribute to the construction of the industry.
