7 月份,245 National Weather Station daily maximum temperature exceeded 7 月历史极值;同时,疫情防控形势向好,Enterprises speed up the pace of resumption of work and production,Power load hits record highs.Coal as the main power supply in our country,用不足 50% 的装机占比,Produced nationwide approx 60% 的电量,Satisfied super 70% peak load demand.

Coal power as a kind of thermal power generation,The heat energy produced by coal during combustion,Converting a power-generating power plant into electrical energy.Using map software 2D、3D 和 GIS 可视化技术结合倾斜摄影和数字孪生技术,Build power plants, different unit area、coal handling area、Chemical water treatment area、Common system area、Living office area、3D Visualization System of Main Transformer and Booster Station Area.Use ubiquitous perception、自适应、智能融合与互动化,Let the thermal power plant in the engineering design、生产调度、过程监控、故障诊断、运营管控、Visualization operations such as different link to realize intelligent management.

HT for Web GIS 支持对不同地图瓦片服务或数据、航拍倾斜摄影实景的 3DTiles 格式数据以及城市建筑群等不同的 GIS 数据的加载,同时,结合 BIM 数据轻量化、三维视频融合以及 2D 和 3D 的无缝融合等技术优势,在 GIS 系统中对海量的 POI 数据、交通流量数据、规划数据,Status data such as variety show.

基于 HT for Web 和 GIS The smart thermal power plant realizes the digital twin of thermal power plant by acquiring 3D scene data.3D technology based on digital twin,将物联网、人工智能、大数据等新 ICT 技术进行整合,Safety module for thermal power plants、Environmental module、All-round digital construction of production modules,Build into a new generation of technology、高效、安全、绿色、A healthy thermal power plant.Weather simulation based on weather data,根据具体的需求,Show rain、Snow different meteorological data such as 3 d simulation results.Also can access to the meteorological data,Prepare for bad weather before it hits.

There are mainly two ways to obtain 3D scene data of thermal power plants: aerial photography modeling and artificial modeling..

航拍建模,也称倾斜摄影实景三维.通过从一个垂直、四个倾斜、The perspective of five different synchronization acquisition images,以大范围、高精度、高清晰的方式全面感知复杂场景,获取到丰富的建筑物顶面及侧视的高分辨率纹理.It can not only reflect the real information of the ground objects,Also by positioning、融合、建模等技术,Generate a 3D plant model with geographic coordinate system information.Aerial modeling can accurately andGIS 匹配,OSGB 模型数据具有多细节层次(Level of Detail, LOD),系统可以根据用户浏览时和场景的距离显示不同精度的 LOD 层级模型.

人工建模,使用 3dsMax、Maya、C4D 等建模软件,基于影像数据、CAD 平面图或者拍摄图片估算建筑物轮廓与高度等信息进行人工建模.However, the architectural texture deviates greatly from the actual effect.,The production process also requires a lot of manual participation;Data production cycle is long,时效性较低.人工建模要和 GIS 匹配需要人工进行空间矫正配准.

性能上,Tilt photography is suitable for large complex factory or buildings,Scenes can be quickly generated from the data collected by aerial photography,To avoid spend a lot of time for manual modeling.Loading in a hierarchical manner,不受性能限制,It can carry the scene scale that cannot be carried by manual modeling.

效果上,Oblique Photography WYSIWYG,Displays all photographed objects,But the effect on artificial modeling,There will be blurring of model textures after zooming in,Problems such as loss of model details.At the same time, the flexibility of tilt photography is not as good as manual modeling,To implement a click event on a single building model,Monomerization is also required,And some animation effects cannot be achieved from the model level,such as dismantling、透视、Parts disassembly, etc..

成本上,Large-scale aerial photography plus batch extraction and texture from oblique images,Can effectively reduce the cost of 3D modeling,Improve model productivity,Reduced economic cost of 3D model data acquisition.

on the construction period,通常 1-5 平方公里面积,采集数据+生成模型在 1-2 周左右,Manual modeling depends on the building/Equipment quantity and complexity,Usually a single plant modeling cycle is 1-4 个月之间.
