The Water Management System Of Zhang He Based On SD Technology

Shortage of water resource has been the problem of China as well as the world. We should attach importance to water management in order to better rational use of existing water resource. Therefore, it is very necessary to research and establish the water management system that it is an intelligent, visual, on-line management system.The VR technology(Virtual Reality, VR for short)which emerged in 1990s,is a new type of comprehensive information technology. It can bring about a virtual environment throughout computer technology. This type of environment could be perceived by human through the sense of sight,audition and touch. Users could directly observe the environment, and interact with the environment. It could offer a realistic feeling. During 20 years'exploration and research, VR technology has been put in use in many fields, like virtual reality drive exercise for aircraft,ship and vehicle, virtual reality architecture, virtual reality game, virtual reality film art etc.Along with the development of computer technology, it is possible to carry out VR on PC. Put VR technology in the water management system of Zhang He, It can provide a 3D visual environment which is interactive, and so, the water resource of Zhang He could be managed much well, and users could have more convenient way to observe and evaluate.In the topic VRML technology is the main design software. CAXA entity design 2006 three-dimensional modeling software and Visual Basic6.0 are the auxiliary softwares. The topic uses these softwares to establish a virtual water management system of Zhang He. In the virtual environment, not only can achieve a virtual tour, but also can display the information of data tables and images through Visual Basic6.0 and spreadsheet. The topic discusses modeling,Interaction and optimizing detailed , also has pivotal technique and solving methods in every step, and Enumerate some problems which are not solved at last.
