Abstract
An optical fiber sensing system according to the present disclosure includes an optical fiber (10) provided on a water discharge gate (30) of a reservoir or in a vicinity of the water discharge gate (30), a reception unit (21) configured to receive an optical signal including a vibration pattern from the optical fiber (10), and a detection unit (22) configured to detect whether an opening amount of the water discharge gate (30) is appropriate, based on a vibration pattern included in the optical signal.
Claims20
An optical fiber sensing system comprising:
- an optical fiber provided on a water discharge gate of a reservoir or in a vicinity of the water discharge gate;
- a reception unit configured to receive an optical signal including a vibration pattern from the optical fiber;
- and
- a detection unit configured to detect whether an opening amount of the water discharge gate is appropriate, using the vibration pattern.
An optical fiber sensing apparatus comprising:
- a reception unit configured to receive backscattered light from an optical fiber provided on a water discharge gate of a reservoir or in a vicinity of the water discharge gate, and to determine a vibration pattern using the backscattered light;
- and
- a detection unit configured to detect whether an opening amount of the water discharge gate is appropriate using the vibration pattern.
