从部队阵地安全监测的实际需要出发,提出了光纤光栅传感技术在此方面的应用设想。介绍了光纤光栅传感技术的基本原理和众多优点,比较了主流解调技术的优缺点并确定选用F-P解调方法;以S3C2410A微处理器为控制和处理核心,设计了解调系统总体方案和各组成模块;针对监测任务点多量大的特点,采用多路复用和循环扫描的方式实现大范围多参数监测。对某装备通道进行的应变监测实验,用温度补偿消除交叉敏感,实际扫描频率为50Hz,波长分辨率达到4pm,但部分光路损耗较为严重致使传感器数据无法获取。文章为以军事应用为方向的光纤光栅传感技术的研究提供了技术参考。
Based on the actual needs of the security monitoring of the position of the troops, the application of FBG sensing technology in this aspect is proposed. The basic principles and many advantages of FBG sensing technology are introduced. The advantages and disadvantages of the mainstream demodulation technology are compared and the FP demodulation method is selected. With the S3C2410A microprocessor as the control and processing core, the overall demodulation system design and the For a large number of monitoring mission characteristics, the use of multiplexing and cyclic scanning approach to achieve a wide range of multi-parameter monitoring. Strain monitoring experiments on a certain equipment channel were performed with temperature compensation to eliminate cross-sensitivity. The actual scanning frequency was 50 Hz and the wavelength resolution was 4 pm. However, some optical path loss was more serious, which made sensor data unavailable. The article provides a technical reference for the research of fiber grating sensing technology based on military application.
