摘要
介绍了火灾烟雾探测方法,设计了一个基于火灾烟雾图像模糊特性的地铁列车火灾探测报警系统。系统主机通过车载视频监控系统获取车厢内图像,利用图像空域微分法火灾探测法检测出火灾的发生,将火警信息通过数传电台发送至附近车站。车站应急照明疏散控制器依据火警信息生成疏散预案并联动BAS系统送风设备,引导乘客从安全方向疏散。实验结果证明,该系统探测火灾发生的准确率高,运行稳定。
This paper introduces the technique of fire smoke detection, and designs a metro trains＇ fire detection and alarm system based on fuzzy feature of fire smoke images. The system＇s host computer acquires images of train carriages through the video monitoring system, and detects fire using image spatial differential method. Then fire alarm information is sent to the nearby station via the data radio, through which the emergency lighting and evacuation controller generates evacuation plan and sends directives to start the BAS system＇s blowing equipment, guiding passengers to safety evacuation. Experimental result shows that the system is reliable and has a high accuracy rate of fire detection.
