Brief description of the drawings
The step of Fig. 1 is the method for positioning ODN network segment faults in embodiment of the present invention schematic flow sheet；
Fig. 2 is the structural representation of the system of positioning ODN network segment faults in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention solves prior art by providing a kind of method and system of positioning ODN network segment faults
In the technical problem that ODN network failures cannot be positioned.
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
A kind of method of the positioning ODN network segment faults for providing in embodiments of the present invention, is applied to include and sequentially connects
In the OLT device that connects, P cross-connecting box, N number of optical splitter, the network of M home gateway, OLT device connects P by main road optical cable
Individual cross-connecting box, P cross-connecting box connects N number of optical splitter by branched cable, and N number of optical splitter connects M family by covered wire cable
Front yard gateway, M>N>P, P are positive integer, specifically, the multiple cross-connecting boxes of OLT device connection, the multiple light splitting of each cross-connecting box connection
Device, the multiple home gateways of each optical splitter connection, forms the form of tree root.
As shown in figure 1, the method is specifically included：S101, warning information or handed over by P that collection is reported via OLT device
The fault message that case, N number of optical splitter, M home gateway are regularly reported is connect, the warning information and fault message can react current
Malfunction, i.e., the failure that fault type and those network terminals are reported.
Then, S102, is analyzed to the warning information or fault message；S103a, when analysis obtains a certain home gateway
Break down, when other online home gateways are normal under same optical splitter, it is determined that break down the covered wire cable part；
S103b, breaks down when analysis obtains all online home gateway under a certain optical splitter, online its under same cross-connecting box
When his optical splitter is normal, it is determined that break down the branched cable part；S103c, when analysis obtains the institute under same cross-connecting box
There is online home gateway to break down, it is determined that to break down backbone optical cable part.The fault message includes thering is disconnected fine, disconnected
Electricity or light decay situation not up to standard.
In a particular embodiment, it is described by taking the failure for disconnected fibre occur as an example：
When analysis obtains online one family gateway the situation of disconnected fibre occurs, other online home networks under same optical splitter
Guan Jun does not break fine, then determine that disconnected fibre occurs in the covered wire cable part, the disconnected fibre in the covered wire cable part includes rubber-insulated wire light
Situation and covered wire cable line and the disconnected fine situation in the connectivity port of home gateway that cable breaks fine.
When there is breaking fine situation in all online home gateway that analysis is obtained under some optical splitter, same handing-over
When other online optical splitters are normal under case, the disconnected fibre in the branched cable part is determined that, the disconnected fibre in the branched cable part is included
Situation and branched cable line and the disconnected fine situation in the connectivity port of optical splitter that branched cable line breaks fine.
Broken down when analysis obtains all online home gateway under same cross-connecting box, it is determined that backbone optical cable part
Break down, the disconnected fibre in the backbone optical cable part includes the disconnected fine situation of trunk cable line and trunk cable line is connected with cross-connecting box
The disconnected fine situation in port.
So as to by above-mentioned analysis, be accurately positioned the position of fiber cut failure, it is easy to rapid-maintenance.
The situation of power-off is also ibid.
Light decay situation not up to standard is as follows：
If being more than default light decay value according to the light decay value that analysis obtains a certain home gateway, and under same optical splitter other families
The light decay value of gateway is less than or equal to the default light decay value, then judge that the light decay value of the covered wire cable part of the home gateway does not reach
Mark, currently, the covered wire cable part light decay value is not up to standard include covered wire cable line situation not up to standard and covered wire cable line with
The light decay value of home gateway connectivity port situation not up to standard, the default light decay value can be the arbitrary value in 25dBm ~ 30dBm.
Just no longer it is described in detail in embodiments of the present invention.If obtaining all online home gateway under a certain optical splitter according to analysis
Occur that light decay value is not up to standard, when the light decay value of other online optical splitters is up to standard under same cross-connecting box, it is determined that the branch
The light decay value of cable portion is not up to standard, and the light decay value of the branched cable part light decay value for including branched cable line not up to standard is not
Situation up to standard and the branched cable line situation not up to standard with the connectivity port of optical splitter.If obtaining same cross-connecting box according to analysis
Under all online home gateway light decay value it is not up to standard, it is determined that backbone optical cable part light decay value is not up to standard, naturally also includes
Trunk cable line light decay value situation not up to standard and the trunk cable line situation not up to standard with the connectivity port of cross-connecting box.
By above-mentioned technical scheme, the abort situation in ODN network segments can be accurately positioned, be easy to dimension in time
Shield.
Based on identical inventive concept, the embodiment of the present invention additionally provides a kind of system of positioning ODN network segment faults.Such as
Shown in Fig. 2, including data acquisition server 201, data analytics server 202 and be sequentially connected with OLT device 203, P friendship
Connect the ODN network equipments of case 204, N number of optical splitter 205, M home gateway 206；Data acquisition server 202 be used for gather by
Warning information that OLT device is reported or the fault message reported by P cross-connecting box, N number of optical splitter, M home gateway timing；Number
It is used to be analyzed the warning information or fault message according to Analysis server 201, goes out when analysis obtains a certain home gateway
Existing failure, when other online home gateways are normal under same optical splitter, it is determined that break down covered wire cable part；Work as analysis
The all online home gateway obtained under a certain optical splitter breaks down, and other online optical splitters are normal under same cross-connecting box
When, it is determined that break down the branched cable part；Go out when analysis obtains all online home gateway under same cross-connecting box
Existing failure, it is determined that trunk light portion breaks down.
Using the system of positioning ODN network segment faults, precise positioning can be carried out to the segment fault of ODN networks, be easy to dimension
