A control method and system for intelligent light distribution measurement

Abstract

The present invention provides a control method and system for intelligent optical distribution measurement, including: when the optical fiber line fails or there is a risk of interruption, the optical line terminal OLT combines the optical power trajectory graph collected by the optical time domain reflectometer OTDR with the Compare the curves of non-faulty optical fibers to determine the fault points and fault locations on the optical fiber lines; based on the preset intelligent optical distribution switching scheme, the optical time domain reflectometer OTDR controls the optical switch OS on the first optical distribution network equipment ODN1 equipment, Switch communication signals to other non-faulty fiber optic lines. The present invention compares the collected optical power trajectory diagram with the reference curve when the optical fiber works normally, determines the fault information, and the optical line terminal OLT starts the preset switching plan, guides the equipment to change the path in time, and reports itself to the optical line terminal OLT The status information of the device realizes the fast, safe and reliable switching of optical communication signals.

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 cause user communication interruption, but also greatly increase the difficulty of system maintenance.

Simply relying on manual maintenance consumes a lot of time and may not be able to obtain satisfactory results

[0004] With the increasing scale of ODN construction and more and more resources, the traditional ODN resource management methods have many uncoordinated disadvantages

When the user network fails, the ODN network will be repaired. This passive operation and maintenance method often leads to a decline in the quality of the entire network.
