Problems solved by technology

[0004] The present invention solves the problem that existing power optical fiber monitoring equipment has a fixed and single monitoring mode, only monitors the optical power of optical fiber or monopolizes the monitoring mode of the fiber core, and cannot realize automatic and free switching of working modes, wastes optical fiber resources and manual labor, and shares components in the equipment. The low level leads to high equipment cost, and the failure of manual switching of faulty lines leads to long-term interruption of optical fiber communication, etc., providing a dual-mode optical fiber monitoring system and method with protective optical path and self-healing faults

Abstract

A dual-mode optical fiber monitoring system and method with protection optical path and fault self-healing, which relates to the field of optical fiber communication in electric power systems, solves the problem that the existing power optical fiber monitoring equipment has a fixed and single monitoring mode, and the manual switching of faulty lines is not timely, which leads to long-term interruption of optical fiber communication. and other issues, including at least one monitoring unit, each monitoring unit monitors one optical fiber line, realizes free switching between working fiber core monitoring and non-working fiber core monitoring modes, vibration monitoring of working fiber core protection fiber core and faulty fiber core optical path Self-healing and automatic switching; each monitoring unit is composed of a sending end monitoring subunit and a receiving end monitoring subunit, multiple sending end monitoring subunits share the sending end optical path switching module, and multiple receiving end monitoring subunits share the control processor and data acquisition module , an optical power monitoring module, an optical detection module, a non-working fiber core monitoring module, a receiving end optical path switching module, an OTDR, a vibration alarm module, an optical alarm module, a sixth optical switch, and a seventh optical switch.

Description

technical field [0001] The invention relates to the field of optical fiber communication in electric power systems, in particular to a dual-mode optical fiber monitoring system and method with a protective optical path and self-healing faults. Background technique [0002] Because optical fiber communication has the characteristics of large capacity, low loss, and high speed, it has been widely used in power system communication. The power optical fiber communication private network can transmit more and more complex information, ensuring the reliability and reliability of the power optical fiber communication network. Availability is an important guarantee for safe production and efficient operation of power systems. [0003] Since the power optical fiber communication network has the characteristics of high coverage, dense network, difficult maintenance, and great impact of failure, especially the optical fiber laying environment of the urban power system is more complicat...
