基于三维仿真的输（调）水系统实时调控实现平台研究

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。

Simulation and Regulation Platform for Digital Water Grid Based on Virtual Reality Technology

The south-to-north water diversion project being as an example, a simulation and regulation platform for digital water grid based on virtual reality technology is developed coupled the virtual reality technology with numerical simulation model and water regulation model. The key techniques, construction of digital basin virtual reality platform, mass data"s paging dispatch, the collision monitored the technology, used in the system is studied. And the system realized the function, etc., three dimensional visualization and roaming, the two-dimensional navigation charts and the three dimensional scene real-time linkage, integration inquires and demonstrates based on the three dimensional scene, accent water plan lamination functions based on water volume scheduling model, three dimensional water surface kinetic simulator and flow field dynamic visualization demonstration based on hydrodynamics model, virtual simulation of gate operation by remote automatic control. The developed system provided a direct-viewing science decision-making support the platform for project management, the plan and the design of south-to-north water diversion project.
