A control method and system for intelligent optical distribution measurement

Abstract

The invention provides a control method and system for intelligent optical distribution measurement, and the method comprises the steps: enabling an optical line terminal (OLT) to compare an optical power track diagram collected by an optical time domain reflectometer (OTDR) with a non-fault optical fiber curve when an optical fiber line has a fault or an interruption risk exists, and determininga fault point and a fault position on the optical fiber line; and based on a preset intelligent optical distribution switching scheme, the OTDR controls an optical switch OS on the first optical distribution network equipment ODN1, and switches the communication signal to other non-fault optical fiber lines. According to the invention, the acquired optical power track diagram is compared with thereference curve of the optical fiber in normal operation; The fault information is determined, the optical line terminal (OLT) starts a preset switching plan, the equipment is guided to timely changethe path, the state information of the equipment is reported to the optical line terminal (OLT), and rapid, safe and reliable switching of the optical communication signals is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent optical distribution, and in particular relates to a control method and system for intelligent optical distribution measurement. Background technique [0002] In recent years, the power optical cable network has been the main mode of the power communication network. With the application of optical fiber transmission in the power communication network, the automatic management level of massive optical fibers needs to be improved urgently. At present, the optical cable monitoring system cannot realize the timely monitoring of dozens of lines. When the power optical cable network fails, it will directly affect the safety and stability of the production and operation of the entire power system. Once the communication of important links fails, it will cause huge losses to the power grid. . Among them, the power optical fiber distribution communication network is an important part of the power tran...

Problems solved by technology

Among them, the tree structure is the most commonly used. Since the optical distribution frame, optical transfer box, optical splitter, and optical fiber in the ODN have been placed in the field for a long time, the influence of wind, rain, and sun may cause the connector of the optical fiber to loosen and the package of the optical fiber to become loose. Layer shedding, fiber breakage, etc., lead to a decrease in the quality of optical fiber communication or even communication interruption. If it is not discovered in time, it will not only easily
