Ammeter is referred to as terminal.Concentrator is the key equipment in power user power consumption information acquisition system, automatic by down channel
Copy and accept and store the various carrier power meters with carrier communication function, the electricity consumption data in collector, while pass through data feedback channel
Data exchange is carried out with main station system or handheld device；Collector is the equipment for having relay function, passes through itself and carrier wave electricity
The communication interface of table, the related data of ammeter is gathered, then concentrator is reached by the carrier wave or wireless channel of itself；Carrier power meter
For terminal device, the power information for power consumer gathers.
The ID addresses of each terminal are stored with concentrator, the address of each terminal can be by under power network background server
It is downloaded in concentrator.Any one terminal at least can carry out reliable communication with a terminal or concentrator, that is, " isolated island " be not present
Phenomenon.
2nd, layering logic layers
（1）Communication between concentrator and terminal uses " using upper end as absolute masters, point-to-multipoint half-duplex operation "
Mode.When concentrator will be communicated with some terminal of subordinate, first it is sent out paging message with the forms of broadcasting, receives
Terminal to paging message records this unidirectional communication paths and extracts the destination address of calling message, if the purpose of calling message
A response message is identical then beamed back in the ID addresses of address and terminal oneself with the former path for paging message to concentrator, otherwise not
Make any reaction, other terminals record this unidirectional communication paths if the response message that this terminal sent is received, but do not make
Any reaction.
Concentrator first carries out the paging of the first round to all terminals.During layering, in time interval T, concentrator is to terminal
Paging message is sent one by one, if concentrator receives the response message of calling terminal in time T, corresponding page communication
Terminal is marked；If not receiving the response of calling terminal in time T, the terminal is not marked.In paging
Labeled terminal is no longer participate in later paging, if but receiving to record when other terminals send back message and receiving response
The unidirectional communication paths of message.Marked terminal in being paged in the first round is classified as logical layer 1.
（2）Concentrator is after the completion of the first round is paged, if logical layer 1 includes all terminals, layering is completed, no
The second wheel is then carried out to remaining terminal to page.The method of second wheel paging is identical with the method that the first round is paged, but will be with
Relaying of the terminal of logical layer 1 as paging path, is marked qualified terminal, what is marked in the second wheel paging
Terminal is classified as logical layer 2, if having other terminals to receive this response when marked terminal sends back message in the second wheel paging
Message then records this unidirectional communication paths.
（3）If all terminals are all labeled, layering is completed, and otherwise to carry out third round paging to remaining terminal,
The paging of third round the two-wheeled communication path that marked terminal has formed as relaying, will mark during third round is paged in the past
Terminal be classified as logical layer 3, so on, the layering logic layers until completing all terminals, every secondary clearing paging in mark
Terminal record this unidirectional communication paths if thering are other terminals to receive this back message when sending back message.
3rd, the foundation of communication topology figure
Concentrator reads all unidirectional communication paths of all terminals in carrier communication network by the terminal of each level simultaneously
Record, carrier communication topological diagram is built by the unidirectional communication paths of concentrator and all terminals, so as to establish concentrator and institute
There is the communication topology figure of " one-to-many " between terminal..
Route Selection when the 4th, communicating
When concentrator will communicate with some terminal, the minimum communication path of a communication terminal relaying number, selection are selected first
Method：In communication topology figure, inversely recalled from target terminal to concentrator, concentrator selects a communication terminal relaying
The minimum communication paths of number send paging message to communication terminal, and communication terminal selects a communication terminal relaying number minimum
Communication path sends back message to concentrator.When concentrator is communicated with the terminal to be communicated, if received in time T
To the response of communication terminal, then communicate successfully, otherwise attempt other communication paths in next time T.An if end
End all communication paths can not all carry out success communication, then will to this terminal carry out communication lines by reconstruct.
5th, communication lines by reconstructing method
When to the communication lines of a terminal by being reconstructed, all direct communications of this terminal in concentrator are deleted first
Path.Then this terminal is paged in the whole network, it is first determined the logical level residing for this terminal, then resettle with
Communication path between neighbor logic layer terminal.If reconstruct is unsuccessful, illustrate that this terminal has been damaged or moved
Go out network, then this terminal address and its direct communication path are deleted in concentrator.
6th, the dynamic renewal of routing table
For communicating each time, concentrator can remeasure and record the one-way communication of two terminals between adjacent level on communication path
Path, so that the communication topology figure stored in concentrator can dynamically update, and find damage in time or be removed, this
Sample can reduce in meter reading the time delay brought because the reconstruct of communication topology is carried out.
