大空间火灾探测与定位灭火系统设计

Design of fire detection and automatic positioning sprinkling fire extinguish system in large space

介绍一种大空间建筑火灾探测与定位灭火系统的组成及原理、其图像型火灾探测器设计、喷淋控制系统设计和报警图形显示系统。基于图像处理及机器视觉技术实现对监控区域内多个着火点的识别与定位,根据着火点与分布的大空间大流量喷淋头的位置关系,开启距离着火点位置最近的喷淋头,实现定位灭火功能,并通过报警图形显示系统实时动态显示着火点位置及设备运行状态,自动记录报警信息。

The structure and principle, image-type fire detector design, sprinkler controlling system design and alarm monitor system of a fire detection and automatic positioning fire extin- guishing system in large space are introduced. The fires in mo- nitor area can be detected and positioned with image processing and machine vision technique. According to the position rela- tionship of fires and large flow sprinklers, the sprinklers nea- rest to the fires are opened to conduct Positioning fire extinguis- hing. Alarm monitor system displays the position of fires and the state of the equipment, and records the alarm information automatically.
