Description

Technical Field

[0001] The utility model relates to the technical field of power communication, and particularly relates to a real-time scanning detection system for the quality of optical path fiber cores. Background Art

[0002] With the rapid development of the power communication network, power communication optical cables have become increasingly important communication resources. The power communication optical cable network mainly uses OPGW (Optical Fiber Composite Overhead Ground Wire) to be built, laid relying on transmission lines, and carrying production control services such as power system dispatching, protection, and stability control, as well as management information services such as data networks and video conferences. Its importance is self-evident. In the process of building a power communication network, optical cables are the most basic and important communication resources, and their performance seriously affects the safe and stable operation of the power communication network. The spare fiber cores in the optical cable provide guarantee for optical path restoration and future expansion, but they may also fail for various reasons during daily operation. The traditional manual testing method is time-consuming and laborious, and cannot achieve real-time monitoring and rapid fault location. To ensure the stable operation of the power communication system, timely detect optical cable faults, and ensure that the spare fiber cores of the power communication optical cable are available at any time, power communication operation and maintenance personnel need to test and record the spare fiber cores of the power communication optical cable every year to ensure the availability of the spare fiber cores. However, power communication optical cables have the characteristics of wide coverage, long laying distance, and special site locations. The annual testing of spare fiber cores requires a large amount of manpower and time, and cannot achieve real-time monitoring and rapid fault location. Therefore, a system that can monitor in real time and accurately judge the position of the fault breakpoint is needed to improve the maintenance efficiency and reduce the operation cost.

The optical switch matrix module is used to switch the test signals to different optical cable cores. The optical input / output interface module is used to connect to the fiber optic interface and is connected to the spare fiber cores of the optical distribution through pigtails. The optical power test module is used to test the optical signal power transmitted from the opposite side. The OTDR analysis module is used to analyze the reflected light of the line to determine the break point position. The control and display module is used to display the detection results and control the operation of the entire system. The communication module is used to upload test data and receive remote control instructions. The power supply module, the light source module, the optical switch matrix module, and the optical input / output interface module are electrically connected in sequence. The output end of the optical input / output interface module is respectively connected to the input end of the optical power test module and the input end of the OTDR analysis module. The input end of the communication module is a multi-group input and output interface, which is connected to the spare fiber cores of the communication optical cable through pigtails externally and is respectively connected to the input end of the optical power test module and the input end of the OTDR analysis module internally. The input end of the communication module is respectively connected to the output end of the optical power test module and the output end of the OTDR analysis module. The external output end of the communication module is connected to the server side.
