Brief description of the drawings
Accompanying drawing 1 is the flow chart of Cable's Fault localization method of the invention.
Specific embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings.
Referring to shown in accompanying drawing 1, a kind of optical cable of the optical cable broken down in electric power communication optical cable network for assisted lookup
Fault Locating Method, it is based on the performance directly perceived after optical cable breaks down --- and service disconnection is realized, below in the industry interrupted
It is failure business to be engaged in.
The method comprises the following steps：
（1）Whole optical cables in traversal fiber cable network, find out the whole optical cables for carrying any one failure business, and made
For member is put into failure cable aggregation A, all members in failure cable aggregation A are possible to break down.
（2）The optical cable of the minimum radical that can carry whole failure business is found, and doubtful light is put into as member
In cable collection B.Generally, the minimum radical of that is found here can the carry optical cable of all business is 1.Then now, doubtful light
Member in cable collection B carries the optical cable of faulty business for some by only one optical cable itself.
A, setting failure optical cable number i=1.
B, i root optical cables are found out in failure cable aggregation, judge the optical cable that whole members that doubtful optical cable is concentrated are included
Whether all in this i root optical cable；If the optical cable that whole members that doubtful optical cable is concentrated are included is not all in this i root optical cable,
Continuation judges whether this i roots optical cable can carry whole failure business, if this i roots optical cable can carry whole failure business,
This i roots optical cable meets requirement, and being put into doubtful optical cable as a member concentrates.
C, find out in failure cable aggregation i root optical cables whole possible cases complete above-mentioned judgement after, will setting therefore
Barrier optical cable number i adds 1, and repeat the above steps b, until setting the optical cable that failure optical cable number i is included in failure cable aggregation
Untill radical；
Specifically, first, when failure optical cable number i=1 is set, 1 optical cable is found in failure cable aggregation A, judge to doubt
Whether it is included in this 1 optical cable like the member in optical cable collection B, if so, then this this root optical cable for finding can necessarily be carried
All of failure business, then need not separately make to judge again；If it is not, then also needing to determine whether whether is this root optical cable for being found
Whole failure business can be carried.If whole failure business can be carried, this root optical cable that will be found is needed to also serve as member
It is put into doubtful optical cable collection B.1 optical cable of searching is untill possible situation has judged in failure cable aggregation A.
Now, setting failure optical cable number i is added 1, i.e., 2 optical cables is found in failure cable aggregation A, judge doubtful optical cable
Whether the member in collection B is included in this 2 optical cables, if so, in this 2 optical cables that then explanation is found, necessarily at least
A part has been able to carry all of failure business, then without judging it again；If it is not, then judging this 2 optical cables
Whether all of failure business can jointly be carried, if so, being then put into doubtful optical cable using this 2 optical cables as an overall member
In collection B.Find 2 processes of optical cable until the possible situation for finding out two optical cables in failure cable aggregation A judged be
Only.
It is further continued for plus 1 by setting failure optical cable number i, is judged by said process, until setting failure optical cable number i increases
To equal with the optical cable radical in failure cable aggregation A, at this moment, the unit cable that may be broken down in failure cable aggregation A
Or some optical cables are while the combination broken down has been placed into doubtful optical cable collection B.
（3）By each member in resulting doubtful optical cable collection B is according to the radical of its optical cable for being included and is carried
Number of services sorts from less to more, then in the member comprising identical optical cable radical, the few member's hair of the number of services that is carried
The possibility of raw failure is big, if because an optical cable member is carried in theory number of services and the complete phase of failure number of services
Together, then the probability of member's failure is maximum.If the business number for carrying is more than failure business number, otherwise some business are not
Failure, or some traffic failures but undiscovered, need to further investigate, therefore the probability of optical cable member's failure just reduces
.By that analogy, the business number that optical cable is carried is more, and the probability of optical cable member's failure is lower.
By the above method, all possible interruption of optical cables situation in the case of current failure can be obtained, be that next step shows
Field line walking provides accurate foundation.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this that it is not intended to limit the scope of the present invention.It is all according to the present invention
