Abstract

The invention provides an optic fiber monitoring system and monitoring method switching three operation modes freely, relates to the field of power system optic fiber communication and solves the problems that according to an existing optic fiber monitoring device, labor force is wasted, data loss since switching cannot be performed timely and switching cannot be implemented freely. A control processor is connected to an optic power monitoring module, an OTDR testing module, a data acquisition module, an alarming module, a timing controller, a first optic switch and a second optic switch; the control process is assessed with Ethernet through a network interface RJ45 and is connected to an application server and a data server; the data acquisition module is connected to the OTDR testing module and the optic power monitoring module; the timing controller is connected to the OTDR testing module; the optic power monitoring module is connected to the second optic switch; the OTDR testing module is connected to two multiplexers; the alarming module is connected to the data acquisition module. The system is capable of switching three operation modes of operation fibers, bright auxiliary fibers and dull auxiliary fibers freely.

Description

technical field [0001] The invention relates to the field of optical fiber communication in electric power systems, in particular to an optical fiber monitoring system with free switching of three working modes. Background technique [0002] In communication systems, optical fiber communication is a very important communication method. In practical applications, with the continuous development of optical fiber communication technology, due to the advantages of optical fiber with large capacity, high transmission information quality, long transmission distance, stable performance, strong anti-electromagnetic interference, and strong corrosion resistance, it is widely used in power system communication. The application is more and more extensive. [0003] But at the same time, the maintenance and management problems of optical fiber lines are becoming more and more prominent. The number of various new equipment, new systems, and new technologies used in optical fiber communi...
