At present, urban line communication lines are complex and complicated, and communication line maintainers are easy to master under the use conditions of various pipelines and communication rods, so that unnecessary time waste is generated during line arrangement and fault treatment.
Disclosure of Invention
The invention provides an optical fiber wiring and fault positioning method to solve at least one technical problem.
To solve the above problems, as an aspect of the present invention, there is provided an optical fiber routing and fault location method, including:
step 1, acquiring basic pipe network information;
step 2, obtaining relevant information of each pipeline according to the starting node and the ending node of the selected wiring, and planning a path with the highest total link efficiency based on the calculated link cost among the nodes;
and 3, detecting the communication condition of each communication node in real time, reading line information from a background when a communication fault occurs between one two communication nodes, and marking the current line between the two communication nodes as a fault line.
Preferably, step 1 comprises:
step 11, acquiring related information such as cities, areas, streets, numbers, positions and the like of managing and standing wells;
step 12, obtaining basic information of the pipeline, including: the type and diameter of the pipeline, whether the pipeline is self-built, co-built and leased;
step 13, obtaining the optical fiber use and residual conditions under each node and the mutual connectivity among the nodes;
step 14, obtaining basic information of the optical fiber, including: : manufacturer, model, core number, and purchase unit price.
Preferably, in step 2, the communication well and the communication rod are divided into link nodes, and the fiber box and the terminal box are divided into communication nodes.
Preferably, the linking efficiency between nodes in step 2 is calculated by:
(1) Dividing the pipelines between the nodes into an unavailable pipeline and an available pipeline, wherein the unavailable pipeline needs planning construction, and the optical fibers in the available pipeline are divided into a residual fiber core and a non-residual fiber core;
(2) The link efficiency calculation mode between the nodes is as follows:
link efficiency = pipe routing time + fiber link network access time
Wherein, when the pipeline between the nodes is self-built:
1) When the pipeline needs to be newly built during wiring: pipeline wiring time = pipeline construction time + optical fiber wiring time
2) When routing optical fibers with pre-used ducts: duct wiring time = optical fiber wiring time
When the two nodes cannot be communicated through a newly-built pipeline, the connection efficiency between the two nodes is infinitesimal.
Preferably, in step 2, optical fibers are routed according to link levels between the set nodes, wherein the optical fibers with the highest priority are routed by using the existing surplus optical fibers, the optical fibers with the second priority are routed on the basis of the existing pipelines, and the optical fibers are routed by constructing a new pipeline with the lowest priority.
Preferably, in step 2, after the start node and the end node of the newly arranged communication link are selected, all link nodes in an area where two communication nodes are located are obtained, relevant information of the link nodes is obtained, link efficiency between the nodes is calculated, an ant colony algorithm is used for planning the routing path, and finally the routing path with the highest link efficiency between the start communication node and the end communication node is obtained.
Preferably, in step 2, after the optimal routing path is calculated, the information of the relevant nodes on the routing path is updated after the feasibility audit is performed through the field check of the routers.
Due to the adoption of the technical scheme, the invention has the following advantages:
(1) Reducing wiring time
At present, the domestic internet is rapidly developed, the number of communication cables in a city is also rapidly increased, so that maintenance personnel of a communication link can not clearly master the conditions of each communication pipeline in the city, and a large amount of time can be spent on counting the trend and the use condition of the communication pipeline and planning a wiring path when a communication line is newly built. The invention carries out informatization management on the positions and the use conditions of the communication well, the communication rod, the optical fiber box and the terminal box through the communication line in the node city, thereby avoiding spending a large amount of time in the early stage of wiring
(2) Improve wiring efficiency
Because the communication link inside a city is complicated, communication link maintenance personnel can not know the using condition and the trend condition of the communication line, so that the wrong communication line can be selected when the communication line is newly built, and unnecessary wiring time waste is caused. Therefore, the line maintenance personnel only need to check the feasibility of the line on the spot, and the waste of redundant wiring time caused by manually planning the line is avoided.
(3) Reducing time to fault location
Based on the information management of the urban communication line, when the communication line has a fault, the fault location module can quickly locate the node section where the fault occurs, reduce the number of communication line maintenance personnel searching for the fault occurrence point on the spot, and reduce the fault processing reaction time and the searching time.
The innovation of the invention is that: carrying out node-based and information-based management on communication lines in a city; utilizing the ant colony algorithm and the link efficiency among the nodes to plan a wiring path with the shortest line length and the highest link efficiency; and through the line information and the node information, the line communication condition is checked, and the node section where the fault occurs is quickly positioned.

2) Calculation of efficiency of links between nodes
The conditions between the nodes are divided into no available pipeline and available pipeline, and the no available pipeline needs to be planned for construction. There are available channels in which the optical fibers are divided into two cases, residual core and no residual core.
The link efficiency method comprises the following steps:
the link efficiency calculation mode between the nodes is as follows:
link efficiency = pipe routing time + fiber link network access time
When the pipeline between the nodes is self-built:
1) When the pipeline needs to be newly built during wiring: pipeline wiring time = pipeline construction time + optical fiber wiring time

The priority is second: arranging new optical fiber lines on the basis of the existing pipelines
The lowest priority: building new pipelines for optical fibre cabling
4) Routing path planning

5) Routing path audit and routing information update
After the optimal wiring path is calculated, the information of the relevant nodes on the wiring path is updated after feasibility verification is carried out through field check of wiring personnel.
3. Positioning of fault point of communication line
