摘要
通过全尺寸实体火灾和环境试验,研究新型分布智能图像火灾探测(VID)系统在工业场所的应用。该图像型烟雾、火焰探测器包括一个彩色/黑白摄像机、一个近红外摄像机和一个近红外光源。本研究主要在某工业厂房内完成,充分研究了VID系统参数、火源、干扰源和误报源等环境因素对VID系统探测效能的影响。研究表明,VID系统可有效工作于恶劣环境,并有效探测火灾。其中,VID系统的镜头焦距、视场和探测器的安装方式是决定探测性能的重要参数。
The results of full-scale fire and environmental tests to study the use of a newly developed distributed intelligent video image detection （VID） system for the protection of large indus- trial applications. The detector of this new flame/smoke VID system consists of one color camera, one near infrared （NIR） camera and one infrared （IR） light source. The effects of VII） system variables, fire sources and environments on the per- formance of the VID system were investigated in an industrial factory. The VII） system demonstrated its capability to work in various challenging fire and enviromnent conditions presented in the study. The field of view, focus and camera installation mode of the VID system were important factors in determining its detection performance.
