WIND SPEED SPECIFICATION SYSTEM, WIND SPEED SPECIFICATION DEVICE, AND WIND SPEED SPECIFICATION METHOD

摘要

This wind speed specification system comprises an optical fiber (10) installed near a power line (40), a reception unit (20) for receiving, from the optical fiber (10), an optical signal that includes information indicating a sound produced when airflow hits the optical fiber (10), and a specification unit (32) for specifying the wind speed around the optical fiber (10) on the basis of the information that indicates the sound and is included in the optical signal.
