The Study On The Data Warehouse Of Intelligent Building Emergency Management System

In early 1980s, the first intelligent building emerged in the USA, since then, it has been popular in other countries. In China, it started in early 1990s. The development of intelligent building makes a qualitative leap in the function of buildings. And it makes environment economic and comfortable, efficient and safe. Although the research and development of intelligent buildings has made considerable progress, but the current construction accidents are still emerging, which causes tremendous damage and trauma. Safety has become a topic of concern to everybody. So, Intelligent Building Management of unexpected events becomes more and more important.The first solution the intelligent building management system should make is how to timely and effectively get data from numerous subsystems of intelligent building. Facing to huge number of data and different data warehouse, So, how to timely collect data related to sudden incidents, How effectively to use the system to collect data are the researcher's job. This paper takes a certain intelligent building system for example to research the problems related to intelligent building system, then, It presents the deign of data warehouse to provide effective support for emergency management.This paper divides data warehouse system in to several functional models according to the data warehouse management system Of Case-Based Reasoning (CBR) in case of emergencies and combined of the situation of intelligent building system and user's request. It makes total deign of construction of data warehouse, model, and so on.Emergency management system needs to timely and effectively get data. Facing to such huge number of different data, this paper designs an effective link heterogeneous data sources and methods of reading to solve such problems. This paper studies in detail the key technology of data warehouse, establishment and implementation of data acquisition, data management, metadata repository, and so on. Under the proposed design created by intelligent building emergency management system data warehouse, in the actual case the project has achieved a satisfactory test results. The theory and software have wide application potential in the construction of intelligent buildings.
