Abstract
A leakage detection apparatus according to the present disclosure includes: at least one memory storing instructions; and at least one processor configured to execute the instructions to transmit pulsed light to an optical fiber laid in a pipe through which a fluid flows and receive backscattered light from the optical fiber, generate sound data indicating a state of the fluid flowing through the pipe, based on the backscattered light, and detect leakage of the fluid by analyzing the sound data.
Claims9
A leakage detection apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to
