Problems solved by technology
[0002] The icing status monitoring of transmission lines has developed from manual line inspection in the past to the popularization of electronic monitoring systems today. Although the icing status monitoring technology of transmission lines has made great development and progress, it still faces severe challenges.
At present, the online monitoring system for the icing status of transmission lines is mainly composed of various electronic sensors. Therefore, when building a monitoring system, it is necessary to install an additional power supply and lay power pipelines. Although this can ensure a stable power supply, it undoubtedly limits the The environment in which the monitoring system is used
These traditional electronic sensors are all active devices, which are extremely susceptible to interference in the complex electromagnetic environment of high-voltage transmission lines, making it difficult to guarantee the remote transmission and data accuracy of monitoring data
[0003] Therefore, the current electronic transmission line icing monitoring system is difficult to meet the real-time monitoring requirements for the icing status of outdoor transmission lines with harsh geographical conditions and climatic environments.

Abstract
The invention provides an optical cable state monitoring system. The optical cable state monitoring system comprises FBG sensing demodulation equipment (1), distributed monitoring equipment (2) and a data processing center (3), wherein one end of the FBG sensing demodulation equipment (1) and one end of the distributed monitoring equipment (2) are connected to an optical cable to be measured in parallel through a wavelength division multiplexer (4), and the other ends are connected to the data processing center (3) in parallel; and the FBG sensing demodulation equipment (1) monitors the temperature and / or stress of the optical cable to be measured, and the distributed monitoring equipment (2) monitors the position where the temperature and / or stress changes. The temperature and stress change of the optical cable can be accurately monitored.
