Fig. 2 is the process for the embodiment that leading portion equipment completes roam operation in a kind of direction of traffic judgment method of the present invention
Figure.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without creative labor it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
It include a kind of direction of traffic judgment method in technical solution of the present invention.
As shown in Figure 1, a kind of embodiment of direction of traffic judgment method, specifically includes the following steps:
Step S1, headend equipment A and headend equipment B obtains corresponding AP identity information and correspondence and AP identity information respectively
Association；
Step S2, by the new associated AP identity information of the preferential headend equipment for completing roaming and preceding associated AP is roamed
Identity information is compared with the rear headend equipment for completing roaming newly associated AP identity information；
If newly associated AP identity information is set step S3, the rear headend equipment for completing roaming with the preferential front end for completing roaming
When identical for one in associated AP identity information before new associated AP identity information and roaming, then work at present front end is set
For in the tailstock, otherwise work at present headend equipment is in headstock.
In a particular embodiment, when headend equipment A and leading portion equipment B is located between two base station AP,
Headend equipment A is respectively corresponded with headend equipment B to be associated with a base station AP identity information and will correspond to associated base station AP
Identity information correspondence markings be A1, B1,
If wherein leading portion equipment A preferentially completes to roam, leading portion equipment A will correspond to one base station AP identity information of new association,
Labeled as A2, the preferential leading portion equipment A for completing roaming will respectively correspond associated base station AP identity information at this time, and A1, A2 pass through
Switching equipment is sent to another leading portion equipment B, and the leading portion equipment B new associated base station AP identity information for completing roaming is labeled as
B2, and by B2 compared with A1 and A2, judge that leading portion equipment B is located at the tailstock if the value that B2 is equal in A1 and A2；
If wherein leading portion equipment B preferentially completes to roam, leading portion equipment B will correspond to one base station AP identity information of new association,
Labeled as B2, the preferential leading portion equipment A for completing roaming will respectively correspond associated base station AP identity information at this time, and B1, B2 pass through
Switching equipment is sent to another leading portion equipment A, and the leading portion equipment A new associated base station AP identity information for completing roaming is labeled as
A2, and by A2 compared with B1 and B2, judge that leading portion equipment A is located at headstock if the value that A2 is equal in B1 and B2；This implementation
Due to will preferentially complete the leading portion equipment roamed, newly associated base station AP identity information and completion roam a preceding associated base to example
AP identity information of standing is sent to the new associated base station AP of another headend equipment in another headend equipment and with rear completion roaming
Identity information compares, and AP identity information in base station has identical if it exists, then determines that the leading portion equipment of this work is located at the tailstock, if not phase
Leading portion equipment that is same then determining this work is located at headstock, sentences to solve without the signal by automatic train monitor
Disconnected direction of traffic, reduces that judge that operation more simply with the degree of coupling of PIS system more acurrate.
On the basis of above scheme, further, headend equipment A is corresponding to be obtained AP identity information and closes with AP identity information
Connection, and associated AP identity information is labeled as A1.
On the basis of above scheme, further, headend equipment B is corresponding to be obtained AP identity information and closes with AP identity information
Connection, and associated AP identity information is labeled as B1.
On the basis of above scheme, further, a new AP identity information is obtained by corresponding when headend equipment A completes roaming
And be associated with new AP identity information, new associated AP identity information is labeled as A2；
On the basis of above scheme, further, a new AP identity information is obtained by corresponding when headend equipment B completes roaming
And be associated with new AP identity information, new associated AP identity information is labeled as B2.
On the basis of above scheme, further, in step S2, as shown in Fig. 2, include the following steps,
Step S21, it is closed before the current associated AP identity information of the preferential headend equipment for completing roaming of record and roaming
The AP identity information of connection；
Step S22, it by current new associated AP identity information acquired in the preferential headend equipment for completing roaming and overflows
Associated AP identity information is sent to another headend equipment by switching equipment before swimming；
Step S23, the headend equipment that roaming is completed after acquisition corresponds to associated new AP identity information and preferential completion is unrestrained
The corresponding preceding corresponding associated AP identity information of new AP identity information and roaming that is associated with of the leading portion equipment of trip compares.
On the basis of above scheme, further, in step S2, if the preferential headend equipment for completing roaming is headend equipment
A, then the headend equipment for completing roaming afterwards is headend equipment B；
If the preferential headend equipment for completing roaming is headend equipment B, then the headend equipment for completing roaming afterwards is headend equipment
A。
On the basis of above scheme, further, headend equipment is mobile unit.
On the basis of above scheme, further, AP identity information can be base station AP physical address information information.
Above-mentioned technical proposal has the following advantages that or the utility model has the advantages that by the new pass for the headend equipment for roaming preferential completion
The AP identity information of connection and the new associated AP body of associated AP identity letter information and the rear headend equipment for completing roaming before roaming
Part information compares, if thus the rear headend equipment for completing roaming of judgement newly associated AP identity information and it is preferential complete roaming before
End equipment is when newly associated AP identity information and one before roaming in associated AP identity information are identical, it is concluded that current work
Make headend equipment in the tailstock, otherwise work at present headend equipment does not have to solve by automatic train monitoring system in headstock
The signal of system judges direction of traffic, and reduce keeps operation more simple with the degree of coupling of PIS system, judges more acurrate.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
