Power transmission line photonics-electronics converged long-distance monitoring device and method

Abstract

A power transmission line photonics-electronics converged long-distance monitoring device () and method. The device () comprises: a fiber grating demodulation module (), used for transmitting a laser signal to a fiber grating sensor, receiving a first optical signal returned by the fiber grating sensor, demodulating the first optical signal, and outputting the demodulated first optical signal to an edge computing and signal return module (); a convergence module (), used for receiving sensing data of monitoring devices other than the fiber grating sensor on a power transmission line and converging the sensing data, and outputting the converged sensing data to an electro-optical conversion module (); the electro-optical conversion module (), used for receiving the converged sensing data and converting the converged sensing data into a second optical signal, and outputting the second optical signal to the edge computing and signal backhaul module (); and the edge computing and signal return module (), used for computing and encoding the demodulated first optical signal and the second optical signal, and returning the obtained encoded signals to a monitoring master station.
