摘　　要：空芯带隙型光子晶体光纤以其独特的结构和导光机制,具有其它普通光纤无法比拟的优势,这种光纤传感器在气体检测方面灵敏度更高。设计了以这种传感器为检测元件,基于Zig Bee的无线传感器网络的瓦斯监测系统,实验测试结果与样本值比较表明:相对误差在10%以内,基本达到了实时在线监测瓦斯的目的。With special structure and light propagation mechanism,hollow-core bandgap photonic crystal fiber is superior to other common fibers in many aspects,for example,it is more sensitive to detect gas.The sensor is adopted as testing components,and gas monitoring system based on Zig Bee wireless sensor networks is designed.The test results is compared with sample value and the experimental results show that relative error is within 10% and the purpose of on-line gas monitoring is achieved fundamentally.
