基于虚拟现实的城市供水管网仿真系统

建立虚拟城市供水管网运行仿真系统，在三维场景中模拟城市供水管网运行工况，有明确的工程意义。首先建立供水管网工程数据库，以保证仿真模型具有较高的精度。进而利用MultiGen Creator构建供水管网阀门、管段等部件三维模型，建立城市供水管网三维模型。最后采用Vega驱动三维模型，通过VC++ MFC程序设计及EPANET工具箱实现运行工况视景仿真。基于虚拟现实的城市供水管网仿真系统可直观显示城市供水管网信息，实现对供水管网拓扑结构及各种运行工况的仿真。该系统克服传统地理信息系统的局限性，并且具有较高准确性和可靠性。

Simulation System of Urban Water Supply Network Based on Virtual Reality

A water distribution network model which was based on virtual reality was constructed and the state-of-art was simulated in a 3D scene. It works with a clear sense. The water network engineering database was built firstly in this paper to keep the precision of the 3D model. The water network model was constructed after the 3D models of the valves and pipes were made. The model was driven by the Vega and the simulation of the state-of-art was taken by the VC++MFC and EPANET software package. In conclusion, all kinds of data for water distribution network could be shown in the VR based simulation of the water distribution network directly. The topology linkage of the water network and the state-of-art analysis can be realized. The system overcomes the limitation of the traditional GIS system, and the simulation is exact and believable.
