The invention patent "Power transmission line monitoring method and device" (authorization number CN101614602B) discloses a method and device for real-time monitoring of power transmission lines using optical fiber sensors. This method proposes that optical fibers are both sensors and signal transmission lines, breaking through point measurement However, this method requires an additional arrangement of optical fiber sensors along the transmission line and requires close contact with the transmission line, which is difficult to achieve in actual transmission line engineering

However, the distributed optical fiber online temperature measurement system in this patent can only use the sensing optical fiber to measure the temperature of the transmission line, but cannot measure the strain of the transmission line. have important meaning
