Embodiment Construction

[0024] The implementation of the method and device for locating fault points in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 It is a schematic flow chart of the method for locating the fault point in the embodiment of the present application, such as figure 1 As shown, the method includes:

[0026] Step 101: For each optical cable, determine the distance interval of each electrical device that the optical cable passes through relative to the OTDR test point;

[0027] Among them, each optical cable passes through various electrical equipment such as poles, towers, stations, wells, etc. These electrical equipments have a fixed distance with respect to a preset test point on the optical cable. The segments are allocated into the distance ranges of the two electrical devices, so that for each electrical device it has a distance interval on the fiber optic cable relative to the test p...

Abstract

The invention discloses a fault point localizing method and a fault point localizing device. The method comprises the following steps of determining a distance interval of each power device by which each optical cable passes relative to an optical time domain reflectometer (OTDR) test point for each optical cable; conducting the OTDR test on each optical cable, and determining a distance between a fault point of the optical cable and the test point according to an OTDR curve obtained through the OTDR test; and determining a power device corresponding to the distance interval in which the distance stays according to the distance interval of each power device by which the optical cable passes relative to the OTDR test point. The method and the device can realize the localization of the fault point of the optical cable in a communication transmission network.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and device for locating fault points. Background technique [0002] With the development of the modern power communication industry, optical cables are widely used in communication transmission. [0003] Although the existing communication transmission network has functions such as network management and protection switching, it generally does not support the detection of optical cable characteristics. [0004] When the optical cable in the communication transmission network fails, it is impossible to determine the location of the failure, so that the faulty optical cable cannot be quickly repaired. Contents of the invention [0005] In view of this, the technical problem to be solved by the present invention is to provide a fault point location method and device, which can realize the location of the fault point of the optical cable in the communication transmission net...
