摘　　要：介绍了匹配光栅解调技术的工作原理,提出了基于凌阳单片机的光纤光栅传感器解调系统,并给出了该解调系统硬件设计的详细接口图。该系统的扫描频为50Hz,分辨率达1pm。实验结果表明,该系统不仅具有较高的分辨率和测量精度,而且能够实时、准确的实现多点同时测量。A demodulation system of distributed fiber Bragg grating sensor network based on the Sunplus Single-chip Microprocessor controlling is proposed. The principle of the demodulation technique with the matching grating is introduced, A detailed figure of the hardware design for the system is presented, The scanning frequency of this system is 50Hz.The resolution is 0.Spm. The experimental result reveals that the system not only have high resolution and fathom, but also can precisely measure multi-point at the same time in real time.
