高速公路隧道火焰检测技术研究

Research on Flame Detection Techniques in Expressway Tunnels

高速公路隧道火焰检测从20世纪90年代以来一直是研究的热点问题之一。结合目前高速公路隧道中火焰检测技术的研究状况,针对性地对感温光纤、红外以及紫外探测方式在实时性、检测距离等方面进行论述,从火焰的视觉动态特征和静态特征2方面重点阐述利用视频图像处理技术进行隧道火焰检测的思路和特点。研究表明,利用视频图像技术并结合一些辅助成像手段(红外热成像),对于高速公路隧道火焰检测有很好的效果,并提出利用视频图像进行隧道火焰检测的研究发展方向。

The flame detection in expressway tunnel has ever been one of the hot spots of research since the 1990s.In combination with situations of research on flame detection techniques in expressway tunnels at present,this paper intentionally expatiates detection methods by temperature sensing fiber,infrared rays and ultraviolet rays in aspects of real time and detection distance,etc.with emphases on ideas and features of video image processing technology adopted for tunnel flame detection from visual dynamic and static characteristics of flame.The research fulfilled by this paper shows that the video image processing technology with help of some auxiliary imaging means（thermal infrared imaging） exhibits perfect effect in detection of flame in expressway tunnels.The paper also puts forward the development orientation of research on detection of flame in tunnels by means of video images.
