摘要

针对光缆外层断股监测精度和敏感度较低的问题，文章提出了一种基于光纤温度传感的光缆外层断股高精度监测方法。分析光纤温度传感器的数据高速采集电路、信号放大与光/电转换电路等，获取最优监测模式；在光缆上布设光纤温度传感器，进行外层断股温度数据采集；引入小波去噪方法，构建光缆外层温度数据的信号模型，进行有效的信噪分离，完成光缆断股高精度监测。以24B1-45与24B1-08型号的光纤复合架空地线（OPGW）光缆为例，实例实验结果表明，光纤温度传感器的信噪比最高可达152和157 dB，响应频率最高可达6 230和6 310次/s。应用该方法后，保证光缆外层断股监测没有受到过多干扰且具有较高的监测精度，满足高精度监测需求，能够通过温度有效检测出光缆外层断股情况，为偏远地区光缆外层的故障监测提供可靠保障。

Abstract

Aiming at the problem of low accuracy and sensitivity of outer strand breakage monitoring of optical cable

a high-precision monitoring method of outer strand breakage of optical cable based on optical fiber temperature sensing is designed. The high-speed data acquisition circuit

signal amplification and photoelectric conversion circuit of optical fiber temperature sensor are analyzed to obtain the optimal monitoring mode. The optical fiber temperature sensor is arranged on the optical cable to collect the outer strand breaking temperature data. Wavelet de-noising method is introduced to construct the signal model of optical cable outer temperature data

separate the effective signal and noise

and realize the high-precision monitoring of optical cable strand breakage. Taking 24B1-45 and 24B1-08 Optical Fiber Composite Overhead Ground Wire (OPGW) optical cables as examples

the experimental results show that the signal-to-noise ratio of optical fiber temperature sensor can reach 152 and 157 dB

and the response frequency can reach 6 230 and 6 310 times/s. After the application of this method

it can ensure that it is not subject to too much interference with high monitoring accuracy

and meet the requirements of high-precision monitoring. Therefore

it can effectively detect the broken strand of the outer layer of the optical cable through the temperature

which provide a reliable guarantee for the fault monitoring of the outer layer of the optical cable in remote areas.
