Abstract
The present invention relates to can calculate label data distribution field, the data distribution broadcasting method of specially a kind of computable label based on concurrent transmission.This method is directed to distributes data to label using commercial reader, can only carry out one-to-one inefficient operation, reader is served as using general software radio peripheral hardware, perform broadcast data distribution operation, it is allowed to reader concurrent transmission to multiple labels.Multiple label receive informations, but do not reply reader.Last reader checks the data distribution correctness of multiple labels one by one again.If the information that label receives has omission or mistake, reader carries out data distribution operation to this label again, until reader is distributed correctly to label data all in region, the concurrent type frog that reader is realized for multiple labels broadcasts transmission, effectively raises the efficiency that can calculate label data distribution.
Description
Technical field
The present invention relates to the data distributing method that can calculate label, specially a kind of computable label based on concurrent transmission
Data distribution broadcasting method.
Background technology
In existing large-scale radio-frequency recognition system, generally there is substantial amounts of label to be deployed on article, a part is to pass
The RFID tag of system, it is merely able to complete the information of label collected by reader；A part possesses can computing capability
Label, the function except traditional label can be completed, but also the distribution of downlink data can be completed between reader, it is real
Now more complicated operation.In order to effectively manage these have can computing capability label, it is necessary to can constantly be counted to these
Calculate label to be safeguarded, for example, label is increased or changed some existing functions, carried out for the leak of label Program
Repair, label is reconfigured etc..The execution of function above, dependent on efficient data between reader and label point
Forwarding method.
At present, One-to-one communication can only be carried out by carrying out data distribution using commercial reader, will even for multiple labels
Distribute identical information, can only also carry out One-to-one communication.But when transmission for multiple labels, read using commercialization
It is low that device carries out one-to-one downlink data distribution efficiency, it is necessary to reader is served as using general software radio peripheral hardware, therefore,
The present invention proposes a kind of data distribution broadcasting method of the computable label based on concurrent transmission.
The content of the invention
The present invention is in order to solve the problems, such as that existing to calculate label data distribution efficiency low, it is proposed that one kind is based on concurrent
The data distribution broadcasting method of the computable label of transmission.
The present invention adopts the following technical scheme that realization：A kind of data of the computable label based on concurrent transmission point
Broadcasting method is sent out, is comprised the following steps：
(1) serve as reader using general software radio peripheral hardware and carry out information for the computable label in region, it is bright
The quantity of true region interior label.
(2) reader performs broadcast data distribution operation to multiple labels, and label does not reply the distribution command of reader,
It is simply one-side to perform the order being written into.
(3) reader one by one to multiple labels perform reading order, one by one inspection tag be written into the correct of data
Property.If data write-in is correct, the data inspection of next label is carried out；If data write-in is omitted or mistake, then right
The omission of this label or error section carry out data distribution.
(4) reader constantly checks that multiple labels are distributed the correctness of write-in data, until all labels transmit
Data are correct, complete downlink data distributed tasks of the reader to multiple labels.
The inventive method transmits identical data for the label in region, is served as and read using general software radio peripheral hardware
Device, continuous broadcasts downstream data distribution command are read, multiple labels in reader antenna coverage receive distribution life
Order, but reader is not replied, simply passive receive information, the information that will not thus produce between label are done
Disturb.After the multiple broadcast distribution order of reader, then the correctness of distribution data is checked each label one by one, for being lost in label
The part of leakage carries out data distribution operation again.Compared to traditional one-to-one transmission, reader utilizes broadcast type concurrent transmission, greatly
Improve downlink data distribution efficiency.
Brief description of the drawings
Fig. 1 is that reader distributes scene graph for multiple label datas.
Fig. 2 is the inventive method workflow diagram.
Embodiment
The inventive method is described in further detail with reference to example and accompanying drawing：
A kind of data distribution broadcasting method of the computable label based on concurrent transmission, comprises the following steps：
What is followed due to commercial reader is EPC C1G2 agreements, if utilizing commercial reader to perform data downstream distribution behaviour
Make, man-to-man transmission can only be carried out, after can only also transferring a label to multiple labels even if distribution identical data, then
Another label is carried out data transmission.The present invention serves as reader using general software radio peripheral hardware, no longer follows tradition
Radio frequency identification EPC C1G2 agreements, so as to broadcast distribution data to multiple labels, realize reader to multiple labels
Transmission.Reader is served as using general software radio peripheral hardware, first has to enter the label in region the collection of row information, it is bright
The quantity of true region interior label, so as to know the label for needing execution downlink data to distribute, how many is individual.
Reader performs data distribution operation to multiple labels to multiple tag broadcast distribution commands.As long as in reading
Device antenna footprint interior label can receive the data distribution operation that reader sends, but simply passive reception,
Reply operation is not carried out to reader.Otherwise, multiple tag return readers will result in the conflict of information, influence reader pair
The descending distribution operation of label.
For multiple labels, it is possible to do not write correct by all data or have portion for write-in data
Divide and omit.Reader after broadcast data distribution command has been performed, then one by one data correctness is distributed to multiple labels
Inspection.If the distribution data that inspection tag is written into are correct, the inspection of data correctness is distributed to next label
Look into；If label distribution error in data or omission, reader enters line number to the holiday and error section of this label again
According to distribution operate, it is ensured that label distribution data it is correct.
The multiple labels of inspection of reader poll are distributed the correctness of write-in data, poll check one by one, Zhi Daoqu
All label distribution data are all correctly written in domain, and so far, reader completes the broadcast for multiple labels in region
The distribution operation of formula downlink data, realizes data distribution of the reader to the computable label based on concurrent transmission of multiple labels
Broadcasting method.
