In conjunction with being not present, also not the present invention claims protection scope within.
As shown in figure 8, the proposed by the present invention kind of optical fiber warning analysis method based on SDH equipment, includes the following steps:
S10 inputs work order information, and calling is cached with SDH equipment information associated in work order information；
If S20 SDH equipment information reporting fiber cores alert, judge the alarm fiber cores whether with the SDH equipment
Within the scope of the fiber cores being connected；
If S30 S20 is judged as YES, judge the alarm time whether in the implementation time range of work order information；
If S40 S30 is judged as YES, the SDH equipment of the alarm is detected, judges whether the alarm is the event of this equipment according to this

Block.
In the present embodiment,To light when the present invention passes through SDH equipment embodiment list in powerline network or overhauls single To optical fiber warning identifying and analyzing method during the manual operation of fibre core, in powerline network SDH equipment ways of carrying out list and When maintenance list is implemented, the manual operation of optical fiber is had, the interruption of corresponding fiber cores is caused to alert, but goes back other reasons to cause The interruption of fiber cores alerts.Because mode list and the single interruption alarm for implementing caused fiber cores of maintenance may not need notice maintenance Personnel's processing, because can be eliminated automatically after the completion of correlation is implemented, but the interruption of fiber cores caused by other reasons alerts
With regard to needing to notify maintenance personnel to handle in time.Described SDH equipment, be it is a kind of by multiple connection, line transmission and function of exchange melt for
One simultaneously transmits network by the integrated information of united net management system operatio.SDH optical transmission device can realize network effectively manage,
The multiple functions such as real time business monitoring, dynamic network maintenance, the intercommunication of different vendor's equipment room, can greatly improve Internet resources benefit
With rate, reduce administrative and maintenance expense, realization flexibility and reliability and the efficient network operation and maintenance；Described mode list, which refers to, to be done
Communication line opens the work order of equal networks adjustment operation；Maintenance singly refers to the work order for carrying out line maintenance.This method passes through optical fiber
Alarm caused by the manual operation feature of core is identified, system alarm analysis efficiency and quality are improved.
The single information of system input mode list and maintenance first, is stored with SDH equipment information in powerline network, because
SDH equipment is connected by optical fiber and fiber optic network routing, therefore can be sentenced according to the interruption alarm reported in SDH equipment information
Disconnected identification, system, into alarm collection and analysis is carried out by way of whole, after SDH equipment report and alarm, are analyzed first reality
Whether the alarm associated fiber cores of relevant device are within the scope of the fiber cores for needing to detect, if belonged within the scope of fiber cores,
Continue to analyze in next step；The time of origin of the network analysis alarm, if implement in time range in place optical fiber work order,
If continuing to analyze in next step in the implementation time range that mode list or maintenance singly identify；System generates alarm
SDH equipment tested, including port from ring, pseudo noise code analysis, optical power test etc. modes, judge alarm whether because
Equipment itself, which breaks down, to be caused, if test result discovering device fault-free itself, continues to analyze in next step；If
Device powers down is unable to test, but can find that the relevant port of all fibre cores can not all return to optical power, can be positioned as optical cable
The failure of section rank, non-fibre core manual operation；System carries out the analysis of fibre core operating characteristics to alarm fibre core, if thinking is
Fibre core operation causes, then the alarm is labeled as fibre core operation and caused, personnel convenient for safeguarding carry out respective handling.
Preferably, the S50 includes:
If S501 S40 is judged as NO, judge that whether all fiber cores of optical cable segment where alerting fiber cores alert, if
This is judged as YES, then analysis is optical cable level faults；
If S502 S501 is judged as NO, it is predetermined whether the actuation time interval of the generation and elimination that judge alarm is less than
Value, if this is judged as YES, analysis is optical cable level faults；
If S503 S502 is judged as NO, the optical power that fiber cores alarm generates surrounding time difference is sampled, judges optical power
Whether damped manner is mutation, if this is judged as NO, analysis is failure caused by optical cable or ageing equipment, if this is judged as
It is that then analysis is the operation alarm of artificial fibre core.
Preferably, the S30 further includes S70, if the S70 is the SDH equipment power-off of the alarm, is judged as optical cable rank
Failure.
In the present embodiment, the S50 is specially the analytical procedure of fiber core manual operation feature, for the people of fibre core
Work operation is implemented with corresponding feature, and system judges whether it is fibre core manual operation according to these features.Fibre core is under the jurisdiction of light
Cable, optical cable generally have tens cores, because carrying different business, the geographical location of fibre core distribution will disperse optical cable fibre core
To different regions, manual operation implements that all fibre cores of same root optical cable will not be operated, if all optical fiber of optical cable segment
Core alerts, and can judge to be optical cable level faults, can be by fibre core manual operation and optical cable level faults by this feature
(optical cable level faults, which have and are not limited to optical cable segment, digs failure caused by disconnected, optical cable or ageing equipment, artificial optical cable segment operation and whole
The connection device powers down of a optical cable segment) it is distinguished；When manual operation fibre core, because of the rate limitation of human action, fibre core
Extracting and being inserted into is to have that the regular hour is poor, moment caused by the other failures of fibre core can be generated and be disappeared by the time difference
Alarm be distinguished.Fibre core extract and insertion, can cause alarm moment generate and remove, but alert generate and remove when
Between, additionally depend on time interval caused by the reaction of equipment network management (equipment control software), above-mentioned time difference and the time
Both intervals relevance is very strong, because of manual operation fibre core, only in moment, and optical cable or ageing equipment, will not all optical cables it is same
Shi Laohua has successive difference, therefore, if when acquisition optical power, it is found that carry out a mutation in a short time (by just
Often to 0 optical power), thus by optical cable or ageing equipment troubleshooting.
Preferably, the S10 includes:
S101 input work order information is stored in the database of communication operation managing and control system, wherein communication operation managing and control system
Database purchase has SDH equipment information associated with work order information；

SDH equipment information after S103 caching formats.
In the present embodiment, the S10 step is the preliminary preparation of alert analysis step of the present invention, and system is defeated first
Enter mode list and overhaul the database that single information is stored in communication operation managing and control system, and the data of this system are stored with and mode
The single and associated SDH equipment information of the single information of maintenance, then by calling SDH equipment information associated with work order information to carry out
It is cached in the memory bank of this system after formatting, to improve performance, accelerates the speed of later period alert analysis.
The present invention also proposes a kind of optical fiber warning analytical equipment based on SDH equipment, for realizing the above method.This is based on
