Abstract
A monitoring system according to the present disclosure includes a cable (20) comprising an optical fiber, a reception unit (31) configured to receive an optical signal including a pattern corresponding to a state of a monitoring target (10) from at least one optical fiber included in the cable (20) and to detect the pattern from the received optical signal, and a control unit (32) configured to detect the state of the monitoring target (10) based on the pattern.
Claims13
A monitoring system comprising:
- an optical fiber in contact with a fence;
- at least one memory storing a computer program;
- and
- at least one processor configured to execute the computer program to:
- receive a backscattered light including a pattern corresponding to a state of the fence from the optical fiber;
- and
- detect the state of the fence based on the pattern and a trained model, wherein the model has been trained according to patterns corresponding to the state of the fence,
- wherein the patterns include vibration patterns and at least one of sound fluctuation patterns or temperature fluctuation patterns.
