Design And Implementation Of Intelligent Facility Visualization System For Emergency Management

The emergency management system can greatly reduce casualties and property losses by preventing and dealing with emergency events.With the popularization of Internet of Things technology and the development of 3D visualization technology,efficient three-dimensional intelligent feedback for emergency management systems becomes possible.At present,scholars at home and abroad have made an endless stream of studies on smart facilities,but most of them focus on the direction of property management,and there are few applied studies on emergency management.Different from traditional emergency management application related visualization system,an intelligent facility system can provide users with rich 3D visualization experience.This paper first introduces the key technology principles of intelligent facility visualization system,such as 3D visualization,model parameterization,humancomputer interaction and other technologies,and analyzes the realization methods and key points of these technologies.Then,demand analysis and scheme design are carried out of the intelligent facility visualization system to be designed.The overall architecture of system design and implementation is proposed,and the functions and implementation schemes of each module in the system are analyzed and designed in detail.Then the module of the system and the corresponding implementation method are introduced,including(1)Scene generation module,including the parameterization standard of model design,the establishment and import of the fine digital model,the rapid separation and reconstruction of any model in the scene;(2)Multi-scale expression module,including classification of important information elements in emergency management and establishment of mapping relationship between scales and element levels;(3)Dynamic visualization display module,including different types of dynamic data access and presentation,database construction standards,and physicallydriven event animation effect production.Finally,the realization effect of the prototype system is given through simulation experiment,and the future development of an intelligent facility visualization system is prospected.
