以南水北调中线工程为例,研制基于三维仿真的输(调)水系统的实时调控实现平台。研究虚拟仿真平台的构建、海量数据的分页调度、碰撞检测、闸门建模等技术,实现场景三维可视化与漫游、二维导航图与三维场景的实时联动、基于三维场景的集成查询与显示、基于水量调度模型的调水方案的分层显示、基于水动力学模型的三维水面动态模拟和流场动态可视化、基于实时调控的闸门可视化动态仿真等功能。该平台可为南水北调中线工程运行管理决策支持系统建设提供技术支撑,并为相似工程提供借鉴。

With the middle line of South-to-North Water Diversion Project as an example,an implementation platform of real-time control for water delivery system based on three-dimensional simulation technology is developed.The key techniques used in the platform,e.g.,virtual simulation platform construction,mass data’s paging dispatch,the collision monitored,gate modeling,are studied.And the platform realizes the functions,e.g.,three dimensional visualization and roaming,the real-time linkage between two-dimensional navigation charts and the three dimensional scene,integration inquires and demonstrates based on the three dimensional scene,layered presentation of water allocation scheme based on water resources scheduling model,three dimensional visualization of water surface and flow field dynamic visualization based on hydrodynamics model,virtual simulation of gate operation by remote automatic control.The developed platform can provide technical support for the construction of operation management decision support system for South-to-North Water Diversion Project,and give reference for similar projects.
