Title:
光ファイバセンシングシステム及び光ファイバセンシング方法
Document Type and Number:
Japanese Patent JP7264252
Kind Code:
B2
Abstract:
The optical fiber sensing method according to the present disclosure includes: sensing optical fibers being redundantly laid (10A1, 10A2); an execution unit (22) that executes sensing with the sensing optical fibers (10A1, 10A2); a detection unit (23) that detects occurrence of a fault in the sensing optical fiber (10A1) of an active system among the sensing optical fibers (10A1, 10A2); and a switching unit (21) that performs switching in such a way that the execution unit (22) executes sensing with the sensing optical fiber (10A2) of a standby system among the sensing optical fibers (10A1, 10A2) when the detection unit (23) detects occurrence of a fault.
