The space sheet for a solar array structure is large in dimension, and flexible to induce complex distortion. It is difficult to measure the distortion. A large-scale flexible test prototype system is built for sheet structure vibration monitoring based on the vibration information of the solar array in space. The system provides an intelligent test method for flexible space structure with embedded sensors and non-visualization reinstruction. Multiple fiber Bragg grating （FBG） sensors are packaged and embedded into the structure with spatial division multiplexing （SDM） and wavelength division multiplexing （WDM）. The sensor interrogator distinguishes wavelength shifts that can be turned into curvature of the curve. The structure shape is reconstructed based on the curvature information and the arc-length, and then displayed. The experiment shows that the system has a high FBG sensitivity. The reconstruction algorithm is fast with high precision. The system has great potential for use in health monitoring of the space sheet structure. 相似文献

In this paper, we present a simple and fast spectra inversion method to reconstruct the temperature distribution along single
fiber Bragg grating (FBG) temperature sensor. This is a fully distributed sensing method based on the simulated annealing
evolutionary (SAE) algorithm. Several modifications are made to improve the algorithm efficiency, including choosing the most
superior chromosome, setting up the boundary of every gene according to the density of resonance peaks of the reflection spectrum,
and dynamically modifying the boundary with the algorithm running. Numerical simulation results show that both the convergence
rate and the fluctuation are significantly improved. A high spatial temperature resolution of 0.25 mm has been achieved at
the time cost of 86 s. 相似文献

本文应用超磁致伸缩材料(GMM)构建FBG的电流传感探头,与ASE光源谱特性解调系统共同组成了交流电流测量系统,对50Hz的交流电流进行测量,并通过温度解调传感实验先对ASE光源谱特性解调进行了定标。通过实验标定ASE光源谱特性解调应变灵敏度系数,最终将交流电流形成的布拉格波长漂移量解调成交变的电压信号输出。该信号与输入电流信号相对应,并且包含了输入电流信号的幅值、频率和相位信息。从示波器测得的输入和输出信号的相似性表明,实验结果与理论分析是一致的,验证了ASE光源谱特性动态解调方法的可行性。 相似文献

1 Introduction 1 The safety and security of bridges have come to be a particular concern by engineers and managers in the recent decades. With the great development of traffic and transportation, a number of highway bridges are expected to be monitored automatically in a monitoring center far from the field. But it is difficult to accomplish the remote monitoring process by conventional methods, in which the state information of bridge have to be collected manually and the data processing done… 相似文献
