摘要
介绍了基于单片机实现光纤Bragg光栅(fiber Bragg grating,FBG)传感器的数据采集系统的实现原理、硬件结构和软件设计。为了实现对FBG传感器的数据采集,采用美国Silicon Labs公司生产的C8051F020单片机对经过可调谐F-P腔解调后的波长进行采集,对得到的数据进行分析处理。实验结果表明该系统可满足井下实时采集的要求,为井下实时采集系统提供可靠的现场测试工具。
A data acquisition system for FBG sensor based on single chip is presented in the paper,where principle,hardware structure and software are respectively introduced.Single chip C8051F020 applies to realize the data acquisition for FBG sensor,which acquires wavelength demodulated by tunable filter,and data is analyzed and processed.The experiment results show that the system can satisfy the demands of real-time data acquisition and will be a liable tool.
