Integrated Application Research And System Development Of CFD Simulation Technology In Operation And Dispatching Management Of Long-distance Water Diversion Project

The long-distance water diversion project is a complex large-scale long-distance water delivery system,which has the characteristics of long water supply line,many kinds of cross buildings,many water diversion gates of control gate and large flow.The safe operation of long-distance water diversion project is related to the safety of people’s life and property.In the process of operation and dispatching management,both the project operation safety and the water supply target should be guaranteed.At present,in the operation and dispatching management process of long-distance water diversion project,problems are often found only through the analysis of monitoring data and daily manual inspection,without the simulation analysis of local buildings in the operation and dispatching process,and there are problems such as poor timeliness of emergency response and difficulty in risk prediction.In recent years,with the continuous development of computer technology,CFD simulation technology,BIM +Web GIS and other technologies,it provides a more solid technical foundation and advanced solution for the operation and scheduling management.Through the simulation analysis of local buildings in the operation and scheduling process of long-distance water diversion project,the scheduling scheme is optimized to provide a strong guarantee for the safe operation of long-distance water diversion project.In this paper,the principle of CFD simulation and operation dispatching management system integration is studied,and the operation dispatching management system of long-distance water diversion project is developed with BIM + Web GIS technology.The research content mainly includes the following aspects:(1)The application of CFD simulation technology and BIM + Web GIS technology in operation and dispatching management of long-distance water diversion project is studied.First of all,this paper expounds the operation and dispatching management of the long-distance diversion project from two aspects: the content and problems;secondly,it analyzes the application of CFD simulation technology in the operation and dispatching management process;finally,it analyzes the application of BIM + Web GIS technology in the operation and dispatching management of the diversion project.(2)This paper studies the method of building a visual platform for operation and dispatching management of long-distance water diversion project based on BIM +Web GIS.Firstly,the implementation mechanism of cesium platform is introduced,including cesium architecture,key classes,scene information rendering and rendering process;secondly,GIS terrain image loading,BIM model format transformation and loading,and model-based Information Association interaction method are studied,and the operation scheduling management visualization platform is built.(3)The integration of CFD simulation technology in the operation and dispatching management system of long-distance water diversion project is realized.Firstly,the principle of secondary development of CFD simulation software is studied to lay the foundation for CFD simulation and system integration;secondly,the integration method of CFD simulation technology in operation scheduling management system is studied,and the technical framework of coupling CFD simulation and operation management system is proposed;finally,the coupling process of CFD simulation and operation scheduling management system is studied,and the CFD simulation is proposed Analyze the implementation method in the system.(4)Based on the above research,the application of CFD simulation,BIM,Web GIS,websocket and other technologies are integrated into the operation dispatching management system,and a long-distance water diversion project operation dispatching management platform integrating CFD simulation and other technologies is developed under the B / S framework.
