摘　　要：针对目前光缆维护及故障诊断存在效率低,故障地理位置定位不准确等问题,提出了分段式光缆智能诊断系统。利用光纤光栅可完全熔入光缆介质的特性,结合光纤光栅波长可识别性能,将光纤光栅和光缆接头盒结合,以光纤光栅为光缆标识点、以接头盒为光缆地理标识点,两者相结合实现光缆分段管理。以光纤光栅波长特性和反射能量变化特性作为光缆识别依据及故障诊断条件,实现光缆分段监测。以接头盒为故障定位基准点实现光缆故障分段定位,进而实现光缆的分段管理、分段监测、分段故障识别以及分段故障地理定位。Aiming at the problems of low efficiency and inaccurate location of faults in optical cable maintenance and fault diagnosis,a segmented optical cable intelligent diagnosis system is proposed.The fiber grating can be fully melted into the characteristics of the optical cable medium,combined with the fiber grating wavelength identifiable performance,the fiber grating and the optical cable joint box are combined,the fiber grating is used as the optical cable identification point,and the joint box is the optical cable geographical identification point,and the combination of the two realizes the cable segmentation management.The fiber grating wavelength characteristics and the reflected energy variation characteristics are used as the optical cable identification basis and fault diagnosis conditions to realize the cable segmentation monitoring.The fault box is used as the fault location reference point to realize the fault segmentation of the cable,and then realize the segmentation management,segmentation monitoring,segmentation fault identification and segmentation fault geolocation of the cable.
