Design And Implementation Of Fire Safety Monitoring System In Large Space Buildings

AbstractVideo fire monitor technology is one of the key technologies of fireprotection and control in large space buildings. video image monitor technology is applied to fire detection and fire source location through the combination of data fusion and video surveillance which is an effective method to solve the problem of fire detection and fire attack in large space buildings. This paper takes fireprotection safety in large space buildings as research object and to design and apply the video fireprotection safety monitor system in large space buildings.This papar analyses the situation of fireprotection technology and fire monitor in large space buildings at home and abroad. According to the fire characteristics, the design methods and the typical problems of fire protection technology in large space buildings, it compares the characteristics and differences between the traditional design methods with the modern design method in fire prevention and discusses the structure design methods of fire prevention in large space buildings and puts forward the key technology of fireprotection safety system and fireprotection monitor in large space buildings.This paper studies the technology of traditional point smoke detection, the technology of infrared shooting detectors,the technology of air sampling detection and the principle of video firedetection, as well as the installation and application of detectors. It determines the preferred video fire detection method in large space buildings and provides the theoretical basis to design video monitor systemThis paper studies the working principle, system composition and hardware of video monitor technology and put forwards the fire monitor methods and systems process which based on video linked with alarm in large space buildings on the basis of the analysis the technology of old fire image alarm system and video fire safety monitor.This paper takes the hall of a railway station as an application example to design and analysis the video fire safety monitor system. According to the structure of the railway station waiting hall, the front layout of system, the integrated structure of system, the structure of field apparatus system, the structure of control cabinet system and the connections of system power supply are designed and the key equipment are selected. At the same time, the linkage system of automatic fire monitor of video fire safety monitor is studied which provide technical support and applications to the fireprotection monitor in large space buildings.
