Abstract
The purpose of the present disclosure is to detect the occurrence of engineering work in the surroundings of a utility pole or a pylon using a simple configuration. This engineering work detection device comprises: an optical signal reception unit for receiving an optical signal from an optical fiber cable installed by a method of overhead installation via a utility pole or a pylon; and at least one memory configured to store instructions; and at least one processor configured to execute the instructions to detect, on the basis of a pattern of vibration of the utility pole or the pylon indicated by the optical signal, the occurrence of engineering work in the surroundings of the utility pole or the pylon.
Claims19
A detection device comprising:
- an optical signal reception unit configured to receive an optical signal from an optical fiber cable provided in an overhead manner via a utility pole or a tower;
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- detect occurrence of an engineering work in a periphery of the utility pole or the tower, based on a vibration pattern of the utility pole or the tower that is indicated by the optical signal;
- and
- detect deterioration of the optical fiber cable based on a time-series change of the vibration pattern.
A detection method comprising:
- receiving, by an optical signal reception unit, an optical signal from an optical fiber cable provided in an overhead manner via a utility pole or a tower;
- detecting, by at least one processor, occurrence of an engineering work in a periphery of the utility pole or the tower, based on a vibration pattern of the utility pole or the tower that is indicated by the optical signal;
- and
- detecting, by the at least one processor, deterioration of the optical fiber cable based on a time-series change of the vibration pattern.
