Research on Fire Detection and Putting out Technology for High and Large-span Space Buildings

Based on the features of high and large space buildings,this paper firstly analyzes the disadvantages of the traditional technology of fire detection and putting out.Then three trends of the development of fire detection and putting out technology are introduced: intelligent data procession by multi-sensor data fusion;fire detection and location by video and digital image processing technology;real-time and high efficient fire putting out by GIS and VR.Along with these trends,the state-of-the-art at home and abroad are illustrated.Finally,the function and module division,software and hardware environment settings are proposed for the development of fire detection and putting out system.
