In order to describe the implementation process of technical solution of the present invention in detail, above-mentioned steps S210~S230 is given into one below
The explanation of step：
In a specific embodiment, step S210 carries out networking according to non-overlapping clustering algorithm, obtains each layer
The mailing address of carrier electric energy meter, and include the step of generate the present communications routing table of concentrator and each carrier electric energy meter：
Sent to current layer carrier electric energy meter by last layer carrier electric energy meter and search table order, received response and search table order
The confirmation acknowledgement frame that next layer of carrier electric energy meter is replied, obtains the next layer of mailing address of carrier electric energy meter；Confirm acknowledgement frame bag
Mailing address containing carrier electric energy meter；
When the mailing address of carrier electric energy meter of the default number of plies is obtained, confirm to complete networking, obtain present communications route
Table.
In a specific embodiment, networking is carried out according to non-overlapping clustering algorithm, obtain ground floor carrier wave electricity
The step of mailing address of energy table, includes：
Sent to each carrier electric energy meter and search table address broadcasting command, will can responded within the stand-by period and search table address broadcast
The carrier electric energy meter of order confirms as ground floor carrier electric energy meter；Stand-by period is in time-sharing multiplex machine according to each carrier electric energy meter
What the summation of the lower Latency response time of system was set；
According to the confirmation acknowledgement frame that ground floor carrier electric energy meter is replied, the mailing address of ground floor carrier electric energy meter is obtained.
Specifically, in the case where data acquisition is not influenceed, concentrator can be initiated regularly to carrier electric energy meter daily
Searching carrier electric energy meter address broadcast instruction (searching table order) is initiated, the carrier electric energy meter that can be responded replies to concentrator
Confirm acknowledgement frame, carrier electric energy meter can not receive the order of concentrator or carrier electric energy meter is damaged and will not do response；Confirm acknowledgement frame
The mailing address of carrier electric energy meter itself can be included, the mailing address of each carrier electric energy meter is unique；
Searching carrier electric energy meter address broadcast is initiated by timing to instruct and receive confirmation acknowledgement frame, enable concentrator certainly
It is dynamic, quick the carrier electric energy meter for changing more is issued to it to be identified.So as to help operations staff quickly to find change carrier wave electricity
Energy table, is reduced manually to live investigation is gone, and operating efficiency is greatly improved.
Further, concentrator initiates to search table address broadcasting command to carrier electric energy meter, can receive the carrier electric power of order
Table replys self communication address response frame.Because concentrator and carrier electric energy meter use power-line carrier communication, and electric power
Line is shared communication channel, and multiple carrier electric energy meters carry out communication simultaneously can occur the collision of information.It should be noted that this
The power line carrier communication occurred in each embodiment is invented, can be referred to low-voltage network circuit as communication port, using certain
Modulation means, data are carried in specific carrier signal, the signal after modulation by non-communicating line propagation to reception
High-frequency signal is separated and is sent to terminal and set by end, receiving terminal by special power line modem from power line
A kind of standby technology.
In order to solve the problems, such as shared channel information collision, various embodiments of the present invention use the side of communication channel time-sharing multiplex
Method, i.e. each carrier electric energy meter for receiving information make corresponding delay according to itself unique mailing address, then to concentrator
Confirmation is returned, shares channel according to the time to reach, it is to avoid the purpose of conflict.
Concentrator by all carrier electric energy meter delayed response times summation set the stand-by period, when reach the stand-by period then
The carrier electric energy meter that these directly can be communicated with concentrator is used as spanning tree (network topology structure is a kind of tree)
Ground floor, optionally, the sequencing that concentrator can return to acknowledgement frame according to carrier electric energy meter is numbered.
When concentrator is arrived to the stand-by period that all carrier electric energy meters of ground floor are replied, concentrator will be all of with ground floor
Carrier electric energy meter node continues the wheel of initiation second and searches table order as relaying, and search can be with each node direct communication in ground floor
Node, acknowledgement frame can be replied if it can communicate to concentrator, concentrator is using these carrier electric energy meters as the second of spanning tree
Layer, and the sequencing numbering replied by carrier electric energy meter, the stand-by period that concentrator is set in this wheel is to remove ground floor
The summation of the remaining carrier electric energy meter delayed response time after all carrier electric energy meter response time delay summations；
When concentrator second takes turns the stand-by period then, concentrator is searched using each node in ground floor, the second layer as relaying
Rope can with the node of the node direct communication in the second layer, and using these as spanning tree third layer.And by carrier electric energy meter
Reply to the sequencing numbering of concentrator.
Said process is repeated always until network tree structure reaches the default number of plies, and networking process is finished.
In a specific embodiment, it is 7 layers to preset the number of plies；Search in the data frame of table order and carried comprising the last layer
The mailing address of ripple electric energy meter.
Specifically, the basic thought of sub-clustering is to partition the network into multiple clusters, and each cluster is by one " cluster head " and multiple
" cluster person " constitutes." cluster head " elects the section for being responsible for coordinating and manage all nodes in cluster where other according to certain rule
Other nodes are referred to as " cluster person " in addition to cluster head in point, cluster.These cluster head rows into higher leveled network, in higher leveled network again
Primary network station high can again be formed until highest with sub-clustering, i.e., one leader cluster node can also be simultaneously the cluster person of other clusters
Node.So-called non-overlapping sub-clustering is that cluster person's node can only belong to a cluster, and when cluster person's node already belongs to certain cluster, it will not
Clustering process after participating in again, thus unique communication link is determined between each node, whole network forms tree-shaped knot
Structure.
Meanwhile, the process that carrier electric energy meter is searched table address broadcasting command by concentrator as relay point transmission can be by collection
The mode that middle device writes the mailing address of the carrier electric energy meter as relaying in the data frame initiated is realized.
Further, communicated for narrow-band power line carrier, traffic rate is relatively low, data frame hop count was subject to compared with the day of one's doom
System, the time of the more busy channels of hop count is more long, mistake is easily produced, it is contemplated that restrictive condition, by final tree-shaped knot
Structure is set to seven layers, that is, it is 7 layers to preset the number of plies.
In a specific embodiment, compare the preceding communication lines of present communications routing table and concentrator record by
Table, step can also be included before obtaining the step of changing data according to comparative result and default decision rule：
The sequencing for confirming acknowledgement frame is replied according to each layer carrier electric energy meter, generation includes the communication of each layer carrier electric energy meter
The current communications address list of address；
A preceding mailing address list of current communications address list and concentrator record is compared, in the result for comparing for not
When consistent, confirm carrier electric energy meter change.
Specifically, all of carrier electric energy meter under it is initiated to read carrier electric energy meter communicatedly by concentrator timing
Location broadcasting instructions, the mailing address that carrier electric energy meter is returned is stored in a newly-built row of concentrator according to the arrangement of certain order
In table, then the table is compared with primary carrier electric energy meter mailing address list, if finding, two lists are inconsistent, net
There is carrier electric energy meter change in network.
Various embodiments of the present invention can use non-overlapping clustering algorithm frame during mailing address list is obtained
The communication path of structure search the transmission of table address broadcasting command and confirms the reception (it is no longer repeated herein) of acknowledgement frame, phase
Compared with the method that tradition obtains mailing address, it is whole that various embodiments of the present invention can ensure that all carrier electric energy meter nodes are included in
In individual network, so as to improve be compared by mailing address list, confirm to occur in network the accuracy rate of carrier electric energy meter change and
Stability.
The embodiment of the method 1 of concentrator discriminatory carrier electric energy meter change of the present invention, it is lower all to it by concentrator timing
Carrier electric energy meter initiate read carrier electric energy meter mailing address broadcasting instructions, by carrier electric energy meter return mailing address according to
Certain order arrangement is stored in a newly-built list of concentrator, is then arranged the table and primary carrier electric energy meter mailing address
Table is compared, if finding, two lists are inconsistent, and carrier electric energy meter change occurs in network.Meanwhile, concentrator is by adopting
Current network topology is obtained with non-overlapping clustering algorithm networking, generation have recorded concentrator to the communication lines of all nodes
The present communications routing table in footpath, is then contrasted with the previous routing table that communicates, and is screened according to default decision rule
Go out to change carrier electric energy meter.Concentrator in the present invention is capable of the replacing of automatic identification carrier electric energy meter, dismounting, newly-increased, and base
Change carrier electric energy meter can be informed main website in the present invention, ensure that the load in live carrier electric energy meter information, concentrator
Carrier electric energy meter information in ripple electric energy meter information list, main website is consistent, can greatly improve the collection success of centralized meter-reading system
Rate.
The embodiment of the method 2 of concentrator discriminatory carrier electric energy meter change of the present invention：
In order to technical scheme is expanded on further, while solving traditional centralized meter-reading system easily appears in carrier electric energy meter
Change (including the replacing of carrier electric energy meter, dismountings, it is newly-increased situations such as) when, concentrator None- identified and copy electric less than change carrier wave
Can table data problem, the centralized meter-reading system of the special method with practical application concentrator discriminatory carrier electric energy meter change of the present invention is
Example, illustrates implementation process of the invention；Fig. 3 is the stream of the embodiment of the method 2 of concentrator discriminatory carrier electric energy meter change of the present invention
Journey schematic diagram；As shown in figure 3, may comprise steps of：
Step S310：The logical topological structure of whole network is obtained using non-overlapping clustering algorithm, and it is logical to each
Letter node is numbered according to certain rules, original network topology is defined as, while recording concentrator to the communication lines of all nodes
Footpath.
Specifically, concentrator initiates to search table address broadcasting command to carrier electric energy meter, can receive the carrier electric power of order
Table replys self communication address response frame (being illustrated referring to the frame format in table 1).Using the method for communication channel time-sharing multiplex, i.e.,
Each carrier electric energy meter for receiving information makes corresponding delay according to itself unique mailing address, is then returned to concentrator true
Recognize information.If basic timer is Δ t milliseconds, it is assumed that local communication address is ai, then during the carrier electric energy meter delayed response
Between be ti=Δ tai。
Concentrator sets the stand-by period by the summation of all carrier electric energy meter delayed response times, if carrier electric energy meter can be with
Concentrator direct communication can then return to acknowledgement frame to concentrator after concentrator initiates to search table order for the first time, it is assumed that a total of m
The stand-by period that block carrier electric energy meter then sets concentrator is：Can direct communication have a n block tables, due to signal
On power line transmit when can be interfered make the communication distance of carrier electric energy meter shorten cause can not with concentrator direct communication,
So there remains m-n block tables and be unable to direct communication, then concentrator is needed using this n blocks table as relaying, and data frame is forwarded
To remaining m-n blocks table；
When reaching stand-by period carrier electric energy meter that then these directly can communicate with concentrator as the first of spanning tree
Layer, and be numbered according to the sequencing for returning to acknowledgement frame.

B) control code：C=13H.
C) data field length：L=00H.
D) frame format：
| 68H | AAH | … | AAH | 68H | 13H | 00H | CS | 16H |
2) (order or carrier electric energy meter damage that carrier electric energy meter can not receive concentrator will for carrier electric energy meter normal response frame
Do not do response)
A) control code：C=13H.
B) data field length：L=00H.
C) frame format：
| 68H | A0 | … | A5 | 68H | 93H | 06H | A0 | … | A5 | CS | 16H |
Wherein, A0, A1, A2, A3, A4, A5 are the mailing address that carrier electric energy meter is replied.
When concentrator is arrived to the stand-by period that all carrier electric energy meters of ground floor are replied, concentrator will be all of with ground floor
Carrier electric energy meter node continues the wheel of initiation second and searches table order as relaying, and search can be with each node direct communication in ground floor
Node, acknowledgement frame can be replied if it can communicate to concentrator, concentrator is using these carrier electric energy meters as the second of spanning tree
Layer, and the sequencing numbering replied by carrier electric energy meter, the stand-by period that concentrator is set in this wheel is to remove ground floor
The summation of the remaining carrier electric energy meter delayed response time after all carrier electric energy meter response time delay summations
Arrived when the wheel stand-by period of concentrator second, concentrator is searched for using each node in ground floor, the second layer as relaying
Can with the node of the node direct communication in the second layer, and using these as spanning tree third layer.And returned by carrier electric energy meter
