Description
Technical field
The present invention relates to power-line carrier communication fields, and in particular to a kind of information copy module and its application.
Background technique
In power information acquisition system, main website and concentrator are two important component parts.Main website, also known as center control
Device (CCO) processed, the host node in power line carrier communication network, can regularly send beacon (beacon), control entire net after starting
Network state, CCO can be communicated by serial ports with concentrator, any order that concentrator issues all be sent to by CCO it is each under it
A message that from node, ammeter is reported is translated into the agreement of concentrator identification by CCO, and is reported to concentrator；Concentrator
(CCTT), the equipment mainly from operator control toward CCO send operational order, as meter reading, from Node registry, inquire network
Situation etc., and can show statistical operation result.
Old narrowband carrier power line communication protocols are limited to the old communication system such as narrowband carrier and low-power wireless
Low bandwidth characteristic influence, selection use serial single-point acquiring technology, can be the initiation of concentrator active to a certain ammeter
Data acquisition operations (point is copied)；It is also possible to routing module and initiates to inquire with regard to whether a certain ammeter needs data to acquire to concentrator
Operation (routing active meter reading), and waiting concentrator the data item (or list item) for whether acquiring and acquiring replied is which；
Any in either two kinds of situations, concentrator only issues data acquisition life to a data item of an ammeter every time
It enables, then the data acquisition instructions is sent to the ammeter, the ammeter data item collected according to instruction passback, road by routing module
Concentrator processing is handed over after being received by module；Concentrator is before the data item for receiving passback or the secondary acquisition time-out, no
New acquisition can be issued；Therefore, old main website and concentrator are in design, it is only necessary to meet that serial single-point acquiring is this to be copied
Table mode, there is no the characteristics that bandwidth carrier high bandwidth will be made full use of in view of future.
It is not only power information acquisition system, there are also other numerous information acquisition systems to be again based on narrowband carrier electricity
Line of force communication protocol, such as the information collection of different data acquisition is carried out using intelligence instrument with water information, with combustion gas information etc.
System, they have essentially identical network architecture, also with regard to problem having the same.
It is still a large amount of using based on old narrowband carrier power line communication protocols in current various information acquisition system
The main website and concentrator of design, however, as new generation broadband carrier communication is applied in power information acquisition system, it is old
The information collection of single thread used by some main websites and concentrator and processing mode cause a large amount of Internet resources be in etc.
To state, it is unable to fully the characteristic using bandwidth carrier high bandwidth, causes the efficiency of entire data acquisition that cannot improve, and is risen
The existing main website of grade and concentrator, which go to be adapted to new bandwidth carrier technology, is related to the investment of a large amount of manpower and material resources.
Summary of the invention
The invention is intended to provide a kind of information copy module, using predictive copy reading, without to existing main website sum aggregate

Data cache module, for obtaining and storing collected data；
Data uploading module directly returns to acquisition and storage for when concentrator issues acquisition again
Data are to concentrator.
By the acquisition that concentrator is issued, often carried out whithin a period of time for associated destination address
Identical or associated data item carries out copy reading, and this method is predictable using such acquisition, by learning concentrator
The acquisition issued implements the destination address that data are acquired for concentrator by means such as statistics and/or mathematical operations
With the summary and induction of data item, the destination address and data item that may be acquired in following a period of time are predicted, and
It is collected this partial data in advance before concentrator issues subsequent acquisition；It is issued to corresponding table when concentrator is subsequent
When the acquisition of location and data item, directly collected data feedback to concentrator, should be issued in order
The operation implemented afterwards has advanceed to before acquisition issues so that the time that acquisition is responded shortens significantly, institute
The reason of to use prediction and indirect acquisition total data item is the data item huge number being stored in each instrument, instrument
The quantity of table is also very more, and concentrator only initiates acquisition to a data item of an instrument every time, if thus
Just by all total data items, all acquisition comes up in advance, is bound to cause huge data transfer load, believes that valence than too low, is gone back simultaneously
It needs to be arranged biggish memory space, increases cost.
Point-to-point waiting concentrator issues the mode explicitly ordered and be acquired again in compared with the existing technology, we
Method is utilized the lower layer's network line (data acquisition network line used) being waited for originally, sufficiently benefit
With the characteristic of bandwidth carrier high bandwidth, acquisition in advance is issued just without waiting for order, Internet resources is taken full advantage of, has shortened number
According to the total time of acquisition, to improve the collecting efficiency of power information, data gathered in advance are selected by way of prediction
, letter valence ratio is higher.
Also, the collecting efficiency that information is improved using this law, without being improved to existing main website and concentrator, they
It still operates in original mode, the mode for obtaining data remains transmission order, and retransmits down after waiting returned data
One order, shortening for the time that the raising of collecting efficiency is responded from acquisition, therefore, can be without to net
Under the premise of existing main website and concentrator are transformed or update in network, the effective collecting efficiency for improving information, section
The about cost of network upgrade speed-raising.
Further, the analysis prediction module is also used to, for predicting that the acquisition data successfully and to fail carry out statistical
Analysis.
Predict successfully and acquisition data and for statistical analysis obtained various as a result, can be straight unsuccessfully by accumulating
It connects and acts on prediction or be supplied to background work personnel as the important evidence for instructing its Optimization Prediction method.
Further, the analysis prediction module is used for, and is next collected according to the ammeter sequential prediction in the table archives of acquisition
The destination address that middle device will acquire.
Table archives refer to there is the address file of instrument associated with concentrator, instrument puts in order in table archives
It is in many cases exactly the sequence of concentrator acquisition data, therefore, acquisition table archives can quickly learn adopting for concentrator
Collection sequence, so that preparatory data be arranged to acquire.
Further, the table archives are by sending acquisition under the concentrator.
Using existing resource, acquisition order is quickly obtained.
Further, the analysis prediction module is also used to, by the acquisition destination address in the acquisition being recorded
It is ranked up according to receiving time, to obtain the table archives.
Table archives are voluntarily set up by acquisition historical record, so that reply cannot get the situation of known table archives.
Further, described to issue module automatically and be also used to, to not yet being acquired by concentrator and the data item with timeliness
It carries out periodically re-issuing acquisition；

Detailed description of the invention
Fig. 1 is the schematic block diagram of the data reading system module in the embodiment of the present invention.
Specific embodiment
The present invention is described below in conjunction with the example embodiment in specific background, which refers to that national grid is used
The powerline network of electric acquisition system is based on Q-GDW 1376.2-2013 agreement, has used corresponding bandwidth carrier communication lines
By module, which is mounted in main website used in the powerline network.
Data reading system module in the present embodiment is set in bandwidth carrier communications routing module, it is specific as shown in Figure 1,
Including order obtains module: the acquisition issued for recording concentrator；
Forecast analysis module: it according to the acquisition destination address and data item in acquisition, predicts in following concentrator
The destination address and data item that will be acquired；And it is for statistical analysis for the acquisition data for predicting successfully and to fail；
Automatically module is issued, for being to acquire in advance according to the destination address and data item that predict at interval of a period of time
Data；
Data cache module, for obtaining, storing and updating collected data；
Data uploading module, for checking thing according to the acquisition issued when concentrator issues acquisition again
Whether the acquisition data first stored meet the needs of concentrator, and the number of acquisition and storage is directly returned if meet demand
According to concentrator；
In forecast analysis module, the mesh that following concentrator will acquire is predicted according to the table archives serial number saved in advance
Mark address and data item.
The specific works engineering of the present embodiment is as follows
All AFN02F1 and the AFN13F1 (life in agreement for data acquisition that routing module record concentrator issues
Enable) order acquisition destination address and data item.
After obtaining certain acquisition destination address and data item, prediction concentrator within the next time will be adopted
The destination address and/or data item of collection and the in advance collected data of acquisition and storage；In order to guarantee the instantaneity of data, to that
It is not yet acquired a bit by concentrator and the data with timeliness also needs regularly to be updated.Such as current electricity consumption, with
The passage of time may change, so need to keep its instantaneity before this data is acquired by concentrator,
It at interval of specific time, just resurveys once, until it is acquired by concentrator.
When concentrator issues AFN02F1 and AFN13F1 order again to be acquired, check caching acquisition data whether
Meet the needs of concentrator, if meet demand, illustrate to predict successfully, then the data of direct return cache are discontented with to concentrator
It is sufficient then illustrate prediction of failure, then not data of return cache, while continuing to issue the order to specified ground according to the regulation of agreement
Location simultaneously awaits a response.Compare the destination address and/or data item and the practical mesh issued of concentrator of prediction in the process simultaneously
Address and/or data item are marked, that is, can determine whether and record the correctness of prediction.
The method of prediction includes but is not limited to:
Prediction for destination address
The destination address that will be acquired by the following unit time concentrator of the sequential prediction of ammeter in table archives, logical
The table archives in entire compass of competency can be issued to bandwidth carrier communications routing module in advance by concentrator under reason condition, and big portion
Concentrator can carry out data acquisition according to the sequence in table archives in the case of point；
When concentrator does not deliver down archives or concentrator there is no data acquisition is carried out according to the sequence of table archives
(can be with apparent with table archives by comparison actual acquisition sequence), then concentrator is recorded by the sampling of long period to be needed
The destination address and acquisition order for the ammeter to be acquired to form a local table archives, and are carried out according to the table archives
Predictive data acquisition.
When concentrator uses different acquisition orders in past a few wheel meter readings acquisition, then the side of statistics can be taken
Formula calculates prediction result of the highest multiple electric meter address of repetitive rate as destination address, in the system free time in advance to him
Data be acquired；The multiple electric meter address that can be constant number are also possible to set minimum probability, only occur general
The electric meter address that rate is higher than the minimum probability is just used as the prediction result of destination address.
Prediction for data item
For example, concentrator acquires always with one or more data within a period by statistics, then the concentration is judged
Device needs to carry out the ammeter of destination address the acquisition of one or more data.
Different order may be used for the acquisition concentrator of multinomial data, for example, the first round is to all target electricity
Table acquire A, the second round to all target ammeters acquire B, and so on finally n-th round start again acquire A, such as
This moves in circles.
In another example successively acquiring A and B to a certain ammeter in same round, then to next ammeter one acquisition A
With B until the acquisition of all target ammeters finishes, terminate the round.
By setting arithmetic logic to data with existing, it can which kind of acquisition order predict current concentrator execution is:
Such as when top n acquisition is acquisition A, then for destination address all acquisitions A；
Also or, being alternately present n times when AB, then for destination address all acquisitions A, B two；
The arithmetic logic that can be used in practice is there are also very much, while these arithmetic logics are all that can pass through program code
It realizes, specific implementation is conventional technology, and this will not be repeated here.
In addition the time can also be included into prediction, such as since the service logic of usage scenario is required daily
Same time point or period, concentrator acquire certain one or more data of specific objective address, pass through preset system
After meter and arithmetic logic are inferred to this rule, daily at the time point or before the period, this of destination address is acquired in advance
A little data item.
For routing active meter reading method, although the sequence for initiating meter reading inquiry is specified by routing module, prediction
Mode and the not tangible difference of the logical AND above method, but still there is successively the data acquisition of each ammeter in actual conditions
Point, so routing module preferentially can just collect data ammeter initiate inquiry.
It is worth noting that, above is only certain several prediction technique in the prediction of the invention said, other pass through acquisition
Command history inferred from input data and predicted target address, the data item even method of acquisition time protection scope of the present invention it
It is interior.
Step 5: for statistical analysis for the acquisition data for predicting successfully and to fail, the result of statistical analysis is for continuing
Optimization can carry out the destination address and/or data item of predictive acquisition.
For predict successfully and failure statistical dimension can be it is a variety of, can to certain single ammeter with regard to all list items into
Row statistics, all ammeters can also be counted with regard to single list item, be also possible to the combination of the two, can be extended to bigger
In the range of.
The statistical result of acquisition can directly be applied to influence prediction process and as a result, for example: when discovery is to a certain table
The prediction accuracy of item or a certain ammeter is lower than threshold value, then no longer carries out relevant predictive acquisition；
It can be also used for providing guidance target for background work personnel, assisting their decisions is to need Optimization Prediction side
Method, and how Optimization Prediction method；
Since the result of statistics can be an accumulated result enabling, such tired for stable system
The accuracy for counting statistical result is more preferable.
The accumulated result being also possible in certain time period then needs to recalculate in next period, for often sending out
Change dynamic system, and the real-time of such timesharing accounting result is more preferable.
But for total, in the present embodiment and some other embodiment, for predicting successfully to carry out with the acquisition data of failure
Statistical analysis, continuously carries out.
