摘要
光纤光栅传感技术是目前国内外的一个研究热点,传感组网是该技术的核心技术之一。本文对光纤光栅传感的准分布式传感技术、传感网络技术以及组网中的波分复用(WDM)、时分复用(TDM)和空分复用(SDM)等技术进行了系统的分析,对它们的工作机理、特点进行了分析。
Fiber grating .sensor technique has been a hot research field at home and abroad recently, and sensor network is one of core technique of fiber grating sensor. In this paper, sensor network technique and multiplexing technique, for example, wavelength division multiplexing, time division multiplexing, space division multiplexing, were analyzed systematically. And, the principle of operation and characteristics were described here.
