Abstract

The embodiment of the invention discloses an optical cable monitoring device and method which are used for monitoring the abnormal condition of an optical cable connected with N FBGs in series, and the device comprises: an FBG demodulation module which is used for demodulating wavelength signals of the N FBGs connected in series in the optical cable in real time, and N is greater than or equal to2; The data receiving and transmitting module which is used for sending a first signal to a server when the number M of the wavelength signals demodulated by the FBG demodulation module is smaller than N so as to start an optical time domain reflectometer (OTDR) monitoring module; And the OTDR monitoring module which is used for determining the position where the abnormal condition occurs in the optical cable. After the location information is determined, the OTDR monitoring module autonomously enters a closed or dormant state. Through the mode, the fault monitoring efficiency can be improved,the monitoring cost can be reduced, and the application value is good.

Description

technical field [0001] Embodiments of the present invention relate to the field of optoelectronics, and in particular to a method and device for monitoring abnormalities in optical cables. Background technique [0002] As an important guarantee for the development of the national economy, the power grid is of great strategic significance for its safe and efficient operation. Reliable and effective monitoring of the state of the power grid is an effective way to ensure its safe and reliable operation, and it is also the construction of a controllable, safe, reliable, environmentally friendly and economical intelligent An important guarantee for the power grid. [0003] As an important carrier of optical information transmission, optical cable is particularly important for monitoring the status of optical cable breakage and breakage. However, the inventor found in the process of realizing the present invention that the current monitoring of the optical cable status mainly rel...
