摘要
针对基于TMS320VC33的DSP光纤法珀应变测量仪,对VC33与光电转换模块之间的数据采集进行了探讨,重点介绍了VC33与光电转换模块的命令发送和数据采集的思路及软件实现,在此基础上,得到的光纤法珀应变传感器干涉信号图与理论上传感器的干涉信号图分布基本一致,并对产生差异的原因做了简单说明。验证了该采集技术的可行性。
Intensive study on data acquisition technology of fiber optic Fabry-Perot strain gauge based on DSP has been discussed.Especially,the principle of data acquisition and software development have been implemented.In addition,the experiment has proved that the spectrum data of F-P strain sensor from DSP is primarily in accordance with results of theoretical simulation.There are also some distinctions.The basic reasons for the difference are presented.Accordingly,this technology is effective.
