Problems solved by technology

However, because the device only finds the fault distance, it cannot accurately determine the specific fault point, that is to say, it is impossible to accurately determine which pole or section it is, so it can only be searched section by section by manpower, which takes too long
If it is an urban area or an open area, the difficulty of finding is relatively small, but when encountering an optical cable line with a bad geographical location, the troubleshooting personnel have to carry a large amount of equipment on foot, and they have to constantly check the fault point. , It takes a lot of time and energy, but the efficiency is very low. The low efficiency of troubleshooting seriously affects the user's perception of network usage.

Embodiment 1

[0059] Embodiment 1: For one trunk-Nanguikun one trunk optical cable, select Qujing-Kunming trunk line information collection and fault location. First collect the trunk information, then verify the collected data, and then locate the fault.

[0060] The information collection includes manual collection and automatic collection.

[0061] The manual collection is that the maintenance personnel collect from the first pole to the last pole along the transmission cable line. Starting from the No. 535 marker stone, the data collection starts from the No. 535 marker stone. The specific information collected includes As follows:

[0062] 1. Trunk information, that is, the optical cable line to be calibrated, select "One Trunk - Nanguikun One Trunk Optical Cable";

[0063] 2. For relay segment information, select "Qujing-Kunming segment";

[0064] 3. Choose "direct burial" for the object type; the object types generally include overhead, pipeline, and direct burial (the type corres...

Embodiment 2

[0081] Embodiment 2: For one trunk-Nankun one trunk optical cable, select Yiliang-Kunming section trunk line information collection and fault location. First collect the trunk information, then verify the collected information, and then locate the fault.

[0082] The maintenance personnel collect data from the first pole to the last pole along the transmission optical cable line. The starting pole No. 1 starts to collect data from the No. 1 electric pole. The specific information collected includes the following:

[0083] 1. Trunk information, that is, the optical cable line to be calibrated, select "One Trunk—Nankun One Trunk Optical Cable";

[0084] 2. For relay section information, select "Yiliang-Kunming section";

[0085] 3. Choose "overhead" for the object type;

[0086] 4. The number of the current bar is "1";

[0087] 5. The latitude and longitude of the current pole, the latitude and longitude are automatically obtained by positioning the current pole through the G...

Abstract

The invention discloses a method for accurately positioning a trunk line fault of a long-distance transmission optical cable, belongs to the field of communication, and particularly relates to an optical cable fault positioning method. The method comprises the following steps: acquiring pole and road information of a long-distance optical cable trunk line through a GPS positioning function, performing systematic recording, performing automatic associating, and calculating the pole and road length. When fault information of user complaints or network management alarms exists, a fault section can be calculated and positioned by selecting a starting point and a fault distance of a corresponding rod circuit, fault processing personnel can timely arrive at the site to process according to prompts, and efficient processing of faults of a transmission trunk line is realized.

Description

technical field [0001] The invention belongs to the field of communication, in particular to a method for locating an optical cable fault. Background technique [0002] As an important line support for long-distance communication networks, long-distance transmission optical cable trunk lines are related to the smooth flow of intra-provincial, inter-provincial and international long-distance communication networks. However, because Yunnan Province is located on a plateau and has a complex geographical environment, it is very difficult to plan, route and troubleshoot optical cable lines. [0003] At present, the processing method adopted for the fault of the trunk line of the transmission optical cable is: the fault handling personnel carry a large number of professional instruments to the site to find the fault point and deal with the fault according to the information of the user complaint or the network management alarm, and restore the communication. However, because the ...
