Centralized monitoring and managing system for optical cable resources

Abstract

The invention relates to a centralized monitoring and managing system for optical cable resources. A system structure based on two stages of monitoring and managing platforms and a layer of monitoring and operating platform is at least regulated and controlled by the two stages of monitoring centers of a province and city stage and a region stage, and the monitoring of various modes of optical time domain reflectometer (OTDR) test, light power test, linking test thereof and the like is also provided to an optical fiber in use or a standby fiber in an optical fiber network at an executing lay by a plurality of monitoring stations correspondingly. The system also provides an abundant system managing function; especially, a resource topology drawing of an entire network can be drawn according to the configuration parameter of the system; and the operation of quick and accurate positioning during maintenance and fault examination is assisted by utilizing a geographic information system (GIS) technology. Therefore, according to the system disclosed by the invention, the expense of manpower and financial resources for maintenance and management can be effectively reduced, and the time of fault diagnosis and treatment is effectively shortened, so that the safe and stable running of the entire network is ensured.

Description

technical field [0001] The invention particularly relates to a centralized monitoring and management system for optical cable resources. Background technique [0002] Because optical fiber communication has a series of advantages in terms of transmission distance, transmission rate and stability, its application has increasingly penetrated into various fields of national economy and daily life, and has become an indispensable link. For example, power optical cables have three main purposes: one is relay protection data exchange and command transmission in power grid operation; the other is daily communication work of power grid system and providing transmission channel convenience for telecom operators; Indicates signal delivery. [0003] Since the optical fiber is a physical object, it has a lifespan problem of performance degradation. In addition to the impact of various accidents such as bad weather and external shocks, it is easy to cause damage to the optical cable, in...

AI Technical Summary

Problems solved by technology

[0004] However, in the traditional detection method, technicians first find the optical cable to be tested on the optical distribution frame (ODF), and then use an optical time domain reflectometer (hereinafter referred to as OTDR equipment) to test it, and then manually To summarize and analyze, the workload is heavy and the expense is high, but the maintenance effect is limited

Moreover, once a communication failure occurs, it is necessary to judge from the transmission inspection first, and then find the faulty section to a certain optical cable, and then arrange technicians to use instruments to test and locate, which will delay the fault test and repair time

In addition, due to the bending of the optical cable during actual laying and the length of the fiber coil reserved in the shaft, etc., the fault location is not accurate enough, which affects the repair speed

In addition, for example, the deterioration of optical fiber quality is a gradual process, and the problem may not be seen from the surface or a single test result, but there are already great hidden dangers in the internal structure, so it is difficult to find out by conventional measurement

[0005] On the other hand, as a passive transmission medium, the optical cable has not yet developed its own detection and alarm function, and can only rely on an external system to monitor and manage its status

However, the existing system for maintaining and managing optical cable network resources is just a simple resource recording system, which lacks the linkage with automatic test equipment, and does not have the maintenance scheduling function

With the help of existing optical fiber transmission equipment, it is possible to find a fault in a certain route, but it is impossible to quantify and locate the location of the fault, which will inevitably delay the time to deal with the fault and cause large economic losses; Provide strong support for optical cable planning

[0006] Moreover, the traditional maintenance management is mainly written, which cannot be directly stored in the computer system, resulting in the accumulation of various reports and data, which is very inconvenient for inspection and comparison.

In addition, since the construction and use are different units or departments, there may be some differences in the data collected in the organization of testing and acceptance, which will leave flaws for the later analysis of optical cable status changes and the formulation of update plans.
