Embodiment 1

[0034] like figure 1 As shown, it is a schematic diagram of the implementation flow of the fault location method in the transmission network provided by the embodiment of the present invention, which may include the following steps:

[0035] S11. When a fault occurs in the transmission network is detected, determine optical path information corresponding to the alarm information of the fault.

[0036] It should be noted that the reference figure 2 As shown, the optical path is the physical bearer of the circuit route, which is represented as two ends connected to the transmission equipment port, passing through the ODF (Optical Distribution Frame, optical distribution frame) terminal, and the middle is the link of the optical cable / core, such as figure 2 The link between the OFDs in computer room 1 and computer room 2 is the optical path.

[0037] Specifically, the grid is used to simulate the pipeline network, assuming that the road construction cuts the optical cable, re...

Embodiment 2

[0070] Based on the same inventive concept, an embodiment of the present invention also provides a fault location device in a transmission network. Since the problem-solving principle of the above-mentioned device is similar to the fault location method in a transmission network, the implementation of the above-mentioned device can refer to the implementation of the method, repeat The place will not be repeated.

Abstract

The invention discloses a method and device for locating a fault in a transmission network. The method comprises the steps of when a fault is detected in the transmission network, determining opticalpath information corresponding to alarm information of the fault; determining identification information of pipe wells according to the optical path information; grouping the pipe wells according to the identification information of the pipe wells, and respectively determining a pipe well with the longest identification information in each group; and determining the location of a fault point at which the fault occurs in the transmission network according to the respectively determined pipe well with the longest identification information in each group. By adopting the method provided by the invention, the pipe well in which the fault point is located can be quickly located, thus the fault point is found, the workload of the maintenance personnel is reduced, and the fault locating efficiency is improved.

Description

technical field [0001] The invention relates to a transmission network fault location technology, in particular to a fault location method and device in a transmission network. Background technique [0002] When locating a transmission network fault in the prior art, after detecting a link warning between two network elements, maintenance personnel carry an optical cable fault tester OTDR (Optical Time Domain Reflectometer, Optical Time Domain Reflectometer) to detect the faulty network first. The computer room where the element is located, and then manually check the corresponding optical fiber core from the alarm device port, and then connect the OTDR to measure the distance from the fault point to the local computer room; then start from the local computer room and follow the direction of the optical cable route to find the corresponding In the vicinity of the pipeline or pole position, determine the fault point on site. [0003] The fault location solution provided by t...
