摘要

为了满足煤矿瓦斯监测的需要

阐述了一种利用金属化封装技术长周期光子晶体光纤（PCF）光栅瓦斯体积分数探测器

并在PCF上采用热激法写制长周期光栅（LPG）

并且对系统的温度稳定性进行了测试。测试结果表明:基于PCF光栅的探测器具有很好的温度稳定性

从而可以弥补以往瓦斯探测器的温度影响因素。将制作的瓦斯体积分数探测器在实验室建立的煤矿巷道的物理模型中进行了瓦斯体积分数的测量

在巷道内采用了波分复用技术克服以往有限的复用容量问题

从而准确地确定煤矿巷道内瓦斯的分布情况

当瓦斯体积分数的测量值高于安全设定值时

就会驱动报警控制器发出警示。

Abstract

In order to meet the need of coal mine gas monitoring

describes a photonic crystal fiber（PCF）gas volume fraction detector that is packed using metalized encapsulating technique

and heat shock method is used for PCF to write long period gratings.At the same time

the temperature stability of the system is tested.Test results show that the system has a good temperature stability with the PCF grating detectors

which can make up for the temperature influencing factors compared with previous gas detectors.The physical model of gas volume fraction detector set up in lab for the coal mine tunnel is established to detect the gas volume fraction

and WDM technology is used to overcome the limited multiplexing capacity issues in the roadway.In order to determine the gas distribution of coal mine roadway

when the measured value of the gas volume fraction is higher than the security setting

the system will drive alarm controller to send out warning.
