Abstract: Distributed optical fiber can effectively realize the on-line monitoring of power cable. Because of the characteristics of distributed optical fiber, such as imbalance sensor deployment, frequency collection, strong correlation in perception data and so on, the measured data’s authenticity of power cable was damaged, so as to form omissions and false positives, which put forward higher requirements for the data quality and data management technology of optical fiber sensing technology. Based on this, this paper proposed the hardware and software platform for the health status detection on power cable by distributed optical fiber. According to the omissions and false positives of power cable detection, through the improvement of data acquisition quality, the uncertain automatic detection and repair algorithm for perception data were used to effectively correct the abnormal data, which could improve the quality of power cable sensing data, reduce the incidence of defects in optical fiber detection system, and improve the work efficiency. Finally, the experiments were carried out to verify the algorithm.
