光纤布拉格光栅传感技术在煤矿火灾监测中的应用
Application in the Coal Mine Fire Monitoring of Fiber Bragg Grating Sensor Technology
摘要
Abstract
Aiming at the deficiency of signal fire detection equipment used in the mine low sensitivity, vulnerable to interference and short distances, this paper presents a fiber Bragg grating sensor that was packaged by use of the metalized encapsulating technique. And its working characteristics were analyzed. Related temperature sensing experiment showed that temperature sensitivity of the fire detector is 1.97 to 2.34 times than bare grating, And the coal mine fire alarm monitoring system based on Multi-zone WDM technology with packaged fiber Bragg grating fire detector was put forward, it was applied in a concrete coal mine model founded by our laboratory, and the actual temperature was measured. Experimental results show that the coal mine fire alarm monitoring system can provide detailed temperature distribution of coal mine and give an alarm timely and accurately, making it easier for the workers to find the fire zones accurately.关键词
