摘要
光纤法珀应变传感是20世纪80年代末发展起来的一种新型应变测量技术。相应的应变测量仪逐渐成为国内外研究的热点。针对现有的应变测量仪,提出了基于DSP的一体化光纤法珀应变仪的思路,对VC33与应变测量仪之间的数据采集进行了探讨,重点介绍了VC33与应变测量仪之间数据采集的硬件和软件设计,并做了采集验证实验。实验结果与理论上传感器的输出结果基本一致,验证了该采集技术的可行性,为后面的数据处理及实现一体化打下了良好的基础。
The fiber optic Fabry-Perot strain sensing is a new strain sensing technology at the end of 1980.Correspondingly,the strain measurement gauge is more and more becoming the hot point.Basing on the convenient stain gauge based on PC,the stain gauge integrated with DSP has been discussed.The data acquisition of fiber optic Fabry-Perot strain gauge integrated with DSP has been discussed.Both hardware design and software development of data acquisition have been implemented.In addition,the experiment has been carried out.The result is primarily in accordance with that of theoretical simulation,and proved that it is feasible and effective.
