UTILITY POLE DEGRADATION DETECTION SYSTEM, UTILITY POLE DEGRADATION DETECTION METHOD, AND UTILITY POLE DEGRADATION DETECTION DEVICE

摘要

A utility pole degradation detection system according to the present disclosure comprises: a sensing optical fiber (10) connecting a plurality of utility poles (30); a receiving unit (201) that receives vibration information detected by the sensing optical fiber (10); an identifying unit (202) that identifies the intrinsic frequency of each of the plurality of utility poles (30) on the basis of the vibration information; and an analyzing unit (203) that analyzes the degradation state of at least one of the plurality of utility poles (30) on the basis of the respective intrinsic frequencies of the plurality of utility poles (30).
