Platform area registering result inquiry response is to CCO.It is above-mentioned according to identification used time TTDTAnd identify overtime used time TTDTTJudge whether to terminate platform
The specific steps of area's identification are as follows:
It will identify used time TTDTUsed time T is distributed with identificationTdurIt compares, identify overtime used time TTDTTWith the overtime used time threshold of identification
Value TTDIIt compares, as identification used time TTDTUsed time T is distributed more than or equal to identificationTdur, or identify overtime used time TTDTTMore than or equal to knowledge
Not overtime used time threshold value TTDIWhen, terminate the identification of platform area.
Above-mentioned identification distributes used time TTdurWith identification overtime used time threshold value TTDIDynamic brush is carried out all in accordance with routing node information
Newly, the routing node information includes the quantity and routing rank of network access node.Above-mentioned identification distributes used time TTdurIt is prior
The time distributed by the identification process, allocation rule are as follows: TTdur=2*TTDIAnd TTdur≤ 0.6*Tdur, or, TTdur=
0.6*Tdur。
Note: that is, TTdur≤ 0.6*TdurWhen invalid, enable, TTdur=0.6*Tdur。
Identify overtime used time threshold value TTDICarry out the formula of dynamic refresh are as follows:
TTDI=(1+0.05*R) * TS；
Wherein, R indicates routing rank, and value range is between 1 and 15；TSFor time reference value, which saves with routing
It puts the variation of quantity and changes, the present embodiment is set it to, N≤100, TS=30min, 100 < N≤300, TS=60min,
300 < N≤500, TS=75min, N > 500, TS=120min；Wherein, N is routing node quantity (network access node quantity).
From the foregoing, it will be observed that the present invention is by distributing used time T to identificationTdurWith identification overtime used time threshold value TTDIDynamic refresh

Point quantity and routing rank determine that the process max-timeout time is 0.1*Tdur。
TTCdurRefresh rule: TTCdur=(1+0.05*R) * TTCS, TTCSFor time reference value, the value is with routing node number
The variation of amount and change, be defined as at present, N≤100, TTCS=1s, 100 < N≤300, TTCS=1.1s, 300 < N≤500,
TTCS=1.2s, N > 500, TTCS=1.5s.Wherein, N is routing node quantity.
In step s 200, Active Registration is directly carried out according to judging result, obtains platform area registering result and as searching table
As a result the specific steps reported are as follows:
White list is closed according to judging result, so that all tables in platform area can successful registration；
Active Registration start command is issued, the routing table of the information containing routing node is obtained, record registration used time and registration are super
When the used time, and according to registration the used time and the registration timeout used time judge whether terminate Active Registration, when determine terminate Active Registration when
According to the order of routing table releasing inquiry platform area registering result, enables corresponding routing node close Active Registration and platform area is reported to infuse
Volume is as a result, report gained platform area's registering result and as table result is searched.
Judge whether that terminating Active Registration is same as above according to registration used time and registration timeout used time at this time, that is, when the registration used time
TSNSTMore than or equal to dynamic registration used time threshold value TSdur(TSdur=0.9*Tdur) or registration timeout used time TSNSTTMore than or equal to static state
When registration timeout used time threshold value, terminate the registration of platform area.
Further, according to the order of corresponding routing table releasing inquiry platform area recognition result/query station's area's registering result
Order when be equipped with retransmission mechanism, setting sending times are 3 times in the present embodiment, each retransmission interval time TTCdurAccording to routing
Number of nodes and routing rank determine that the process max-timeout time is 0.1*Tdur。
After table order is searched in recognition methods acquisition in platform area proposed by the invention, further includes interrupting the method for searching table process, search
Table process is to obtain to search the whole process that table command report searches table result, specific steps are as follows:
Interruptive command is obtained, the identification of platform area is judged whether to according to interruptive command stopping or terminates the identification of platform area or knot
Beam Active Registration, wherein the platform area recognition result of corresponding routing node is obtained while terminating platform area and identifying.
That is, the identification of platform area or the registration of platform area, when interrupting the identification of platform area, corresponding routing node can be interrupted according to actual needs
Terminating to report platform area recognition result while platform area identifies, when interrupting the registration of platform area, corresponding routing node terminates actively to infuse
Volume.
Therefore prove that the present invention can interrupt the identification of platform area or platform area registration process at any time, platform area is known according to the actual situation
Not and accomplish it is artificial controllable, thus the scene of reducing because caused by operation error platform area recognition efficiency reduce.
As shown in Fig. 2, introducing a kind of identification side, efficient HPLC platform area based on routing of the present invention with a specific case
Method:
Table is searched in main website starting, and main website issues search instruction by concentrator, and CCO obtains this and searches table instruction, and CCO judges at this time
Tdur>=TTDTVWhether true, the table duration is searched in wherein Tdur expression, and that searches that the table duration issues from main website searches table order
It is obtained in starting frame.TTDTVIndicate preset time threshold, which determines according to platform area scale, and it is small to be set as 4.5 in present case
When.Work as Tdur>=TTDTVIt sets up, CCO successively carries out the identification of platform area, Active Registration, reports the step of searching table result, otherwise CCO
It directly initiates to report after Active Registration and searches table result.
It is supplemented as shown in figure 3, further to above-mentioned case:
Table is searched in main website starting, and main website issues search instruction by concentrator, and CCO obtains this and searches table instruction, and CCO judges at this time
Tdur>=TTDTVIt is whether true；
Work as Tdur>=TTDTVWhen establishment, CCO closes white list and starts 3 minutes timer broadcast notice STA firing platforms
Area's identification, that is, broadcast primary platform area every 3min and identify start command, STA is enabled to receive broadcast starting Zheng Hou firing platform area
Identification.
For CCO in platform area identification process, STA can be continuously added into network, and whenever having STA that network is added, CCO refreshes again
Program internal record TTDTTTimer, i.e. dynamic refresh identifies overtime used time TTDTT；And according to the quantity of network access node and road
By rank, dynamic refresh identifies overtime used time threshold value TTDI；Until TTDTT>=TTDIOr TTDT>=TTdur, CCO terminates platform area
Identification starting and identification process, into the inquiry of platform area recognition result and closing process, that is, it closes broadcast in 3 minutes and starts timer,
And the order of query station's area's recognition result is issued, enable corresponding STA according to closing platform area identification function and reports platform area recognition result.
Work as Tdur>=TTDTVInvalid, CCO closes white list and starts 3 minutes timer broadcast notice STA starting masters
Dynamic registration, CCO is during Active Registration, whenever having STA networking, CCO refurbishing procedure internal record TSNSTTimer, i.e.,
Dynamic refresh registration timeout used time TSNST；Until without new node networking or T in 10 minutesSNST>=TSdurWhen, terminate actively
Registration starting and registration process, into Active Registration result queries and closed stage, that is, it is fixed actively to close the starting of broadcast in 3 minutes
Registration timer, and issue the order of query station's area's registering result, enable corresponding STA according to closing Active Registration and platform area is reported to infuse
Volume result, that is, search table result.
Gained is searched table result and is reported to concentrator by CCO, after concentrator receives the order, is reported to main website, main website according to
The table number that concentrator reports deletes original white list, and then new white list puts into operation to concentrator, concentrator receipts
To after the white list of main website, the synchronous process of an archives is initiated to CCO module, the archives that concentrator is completed between CCO are same
After step, CCO opens white list, and entirely searching table process terminates, and can carry out normal meter reading business.
Due to the recognition methods of platform area, process is complex, and the duration is longer, and once starts, and will be in normally opened shape
