POINT-TYPE HIGH-VOLTAGE POWER TRANSMISSION LINE OPTICAL FIBER DETECTION NETWORK

摘要

The present invention discloses a point-type high-voltage power transmission line optical fiber detection network, comprising a substation control unit, a first wavelength-division multiplexer, a second wavelength-division multiplexer, a third wavelength-division multiplexer, and two base tower monitoring subsystems; the substation control unit comprising a communications control module, an optical signal demodulation module, and a fourth wavelength-division multiplexer; each base tower monitoring subsystem comprising a first optical path selection switch, a second optical path selection switch, a third optical path selection switch, an optical-to-electrical conversion module, a controller, a first electrical-to-optical conversion module, a second electrical-to-optical conversion module, and a tower status sensor array. The present invention improves accuracy in detecting wire vibration due to breeze, wire temperature, and tower angle of inclination in high-voltage power transmission lines, and improves efficiency in detecting the described parameters.
