摘要
在光纤光栅传感系统中,运用多通道智能光纤光栅解调器采集传感信号,并采用TCP/IP协议采集光纤光栅解调器各通道的光谱数据,经过峰值检测和温度补偿后,根据传感器的标定数据换算出对应各监测点的物理量,较好地实现了光纤光栅传感系统的数据采集与处理。并在光纤光栅反射波形的峰值检测技术中引进了指数平移钝化算法替代计算复杂度较高的高斯拟合算法,能有效地减少各种干扰因素引起的峰值波长抖动。
Techniques of data acquisition and processing in fiber grating sensing system were implemented by using a multi-channel intelligent optical sensing interrogator for sensory signals acquisition,which can gather spectra data of each channel via TCP/IP protocols.After detecting peak and compensating temperature,it can convert its calibration data into physical value for each sensor.In peak detection technology of fiber grating reflection waveform,the paper introduced into the exponential weighted moving averag...
