摘　　要：通过对双光纤光栅并联匹配解调原理的研究,提出了基于MSP430F1612单片机的光纤光栅传感器解调系统。利用曲线拟合的方法对压电陶瓷驱动电压与波长偏移量的数据进行拟合计算,实现光纤光栅解调的目的。本文给出了该方案软硬件设计,并对匹配解调法的发展前景进行了论述。A research of the principle of the demodulation technique with double matching grating, a demodulation system of distributed fiber Bragg grating sensor network based on the MSP430 Single-chip Microprocessor controlling is proposed. Using the synthetics curve of the drive voltage of the PZT and wave lengths of the FBG to calculate the tiny offset of wave length, achieve the intention of fiber grating. The design of hardware and software are given and summarizes the foreground of the matching demodulation system.
