Description

Method and system for batch code writing by using RFID group reading technology

Technical Field

The invention belongs to the technical field of radio frequency identification, and particularly relates to a method and a system for batch code writing by using an RFID group reading technology.

Background

UHF RFID chips are usually provided with codes, but the labels are required to be recoded in each application scene according to the application requirement of the software, namely code writing, and the conventional code writing is automatic code writing in sequence, so that each RFID chip is ensured to be written successfully and no wrongly written codes or rewritten codes exist; however, one code writing workload is large, and because the RFID reading range is large and the reading speed is high, the adjacent tags can be easily written with codes, so that the tags needing to be written with codes are not successfully written, and the adjacent tags which are wrongly read write codes. Therefore, the phenomena of missing codes, repeated codes and error codes (half of the codes are written and all the codes are not successfully written) are often found in the future.

The code writing method in the current market focuses on one-to-one code writing, namely, a code of a label is read, then a corresponding code needing to be updated is found from software, and one-to-one coverage is carried out; the batch method only changes manual one-by-one placement into automatic assembly line placement, and in the process, because one-to-one is necessary, the following methods can exist:

1. and (4) repeated coding: the placed label and the label beside are read by the reader-writer at the same time, and then the system cannot distinguish which label needs to be written with codes, and two labels can be written in simultaneously;

2. code missing: one put, it is possible that the code has not been successfully written but the system considers the write to be successful, resulting in one code being missed;

3. error code: for the same reason, it may be that writing a nearby tag without writing the tag that is being written causes an error code.

The speed cannot be increased: this coding is to match the read and write speeds of the reader/writer with the speed of the automation pipeline, otherwise it is likely to cause system confusion.

Disclosure of Invention

The design purpose is as follows: in order to avoid the defects in the background technology, a method and a system for batch code writing by using an RFID group reading technology are designed, wherein the code writing speed is high, the code writing efficiency is high, and invalid code writing labels can be quickly eliminated.

The design scheme is as follows: the design purpose is realized.

1. Firstly, importing a file containing an initial EPC code into a code writing controller, storing the content of the imported file into a cache by the code writing controller, and displaying the content in a plurality of linked lists; secondly, the code writing controller performs full detection and counting on the tags needing code writing through a group reading RFID reader-writer to realize group reading of the tags; and step three, the code writing controller randomly captures the initial EPC codes matched with the number of the tags read by the group in the plurality of linked lists and exchanges the initial EPC codes in the linked lists with the EPC codes of the tags read by the group, so that the design of tag batch code writing operation is realized, and the code writing controller is one of the technical characteristics of the invention. The purpose of this design is: when the code is written in batch, firstly, a file containing an initial EPC code is led into a code writing controller, the content of the led file is stored in a cache and displayed in a plurality of linked lists, then, a label to be written is read in a group mode, detection and counting are carried out before code writing, the label to be written is ensured to be a qualified label which can be read completely, and meanwhile, the actual number of the label to be written is determined; the original information and the effective quantity of the label to be coded before coding are quickly realized through a group reading technology, the code controller realizes batch coding through automatic grabbing and chaotic matching during coding, the label can be ensured to be quickly coded (100 to 500 labels, and all coding can be completed within 1-2 minutes), and meanwhile, the problems of label duplication, code missing and code error caused by external factors can be thoroughly solved.

2. The method is characterized in that the code writing controller is provided with a verification unit, the code writing controller stores EPC codes in all the labels read by the group reading RFID reader-writer into a to-be-detected linked list in the verification unit after batch code writing of the labels is completed, the code writing controller circularly matches the EPC codes in the to-be-detected linked list with the initially written EPC codes in the cache linked list, and the code writing controller can display label information which is not successfully matched through a display interface. The purpose of this design is: some labels with weak performance (which have a certain probability of realizing reading and writing) are provided, although the data information of the labels is successfully read by the group reading RFID reader-writer in the group reading process by the code writing controller, in the data information writing process, the code writing controller cannot necessarily write new data into the labels by the group reading RFID reader-writer, and at this time, the code writing controller considers that the label(s) have successfully realized data updating, but the original data information is still retained by the code writing controller; after the batch code writing of the tags is finished, the code writing controller stores EPC codes in all the tags read by the group reading RFID reader-writer into the chain table to be detected in the verification unit, the code writing controller circularly matches the EPC codes in the chain table to be detected with the initially written EPC codes in the cache chain table, so that whether the tags exist in the batch of the tags or not can be detected (the probability of the tags appearing is extremely low, the tags in the batch are not written in the batch at every time), the tags in the same batch of the tags are not detected, the tags can be put into use, the code writing operation of the tags which are put into use is ensured to be realized by 100%, and the code writing accuracy of the tags is ensured to be 100%.

3. In the cycle matching process, when the number of the labels which can not be successfully matched is less than or equal to the set number, the code writing controller performs countdown number matching on the labels, and when the countdown number is over, the labels which can not be successfully matched are still determined to be damaged, and the code writing design can not be realized. The purpose of this design is: in the cycle matching process, when the number of the labels which cannot be successfully matched is less than or equal to the set number, the code writing controller performs countdown number matching on the labels, and when the countdown number is over, the labels which cannot be successfully matched are still determined to be damaged, the code writing can not be realized, so that the code writing efficiency and the code writing accuracy are considered on the premise of avoiding the occurrence of code writing dead cycle.

4. When the EPC code of the label which cannot be written is displayed on the display interface, the whole label is divided into two groups, then the code writing controller sequentially carries out group reading on the two groups of labels through the group reading RFID reader-writer, when the group reads out that the group of labels comprises the EPC code of the label which cannot be written, the group of labels is divided into two parts, then the code writing controller sequentially carries out group reading on the two parts of labels through the group reading RFID reader-writer, the searching range is sequentially reduced, and the primary screening design of the damaged label is realized. The purpose of this design is: when the EPC code of the label which cannot be written is displayed on the display interface, the whole label is divided into two groups, then the code writing controller sequentially carries out group reading on the two groups of labels through the group reading RFID reader-writer, when the group reads out the EPC code of the label group including the label which cannot be written, the group of labels is divided into two parts, then the code writing controller sequentially carries out group reading on the two parts of labels through the group reading RFID reader-writer, the searching range is sequentially reduced, the screening of the damaged label is realized, and the remaining label can be put into use after the damaged label is screened out, so that the utilization rate of the label is improved; in addition, according to the normal qualification rate control of RFID label production, the maximum probability of unsuccessful code writing of the label with qualified reading performance in the first step of full inspection is below 0.5%, namely, lots (several times or dozens of times) of batch code writing, and only one or two unsuccessful code writing labels can be encountered in one batch of batch code writing labels, so that the overall working efficiency is hardly influenced by the process of finding out the bad label through binary search.

5. After the whole tag is searched for by two for many times, a small amount of good and weed mixed tags are read one by using an RFID reader-writer, and the design of accurate searching is realized. The purpose of this design is: after the overall labels are searched for in two halves for multiple times, a small amount of good and weed mixed labels are read one by the RFID reader-writer, namely, the labels are measured through two halves for primary screening, and the bad labels are searched for quickly and accurately through the fine screening which is read one by one.

6. When the number of the labels read by the group reading RFID reader-writer group by the code writing controller is larger than a set value, the code writing controller writes the codes on the labels in batches; when the labels are written in batches, the label is quickly and quantitatively written by the code writing controller, after the label writing of the set number of labels is completed, the rest labels are set to be unsuccessfully matched by the code writing controller, and then the batch of labels are verified by the code writing controller; after the previous batch of labels are verified, if the number of the remaining labels is less than or equal to the set value, the code writing controller writes the codes of the remaining labels in batches, then the code writing controller verifies the batch of labels, if the number of the remaining labels is greater than the set value, the code writing controller writes the codes of the labels rapidly and quantitatively, after the number of the set labels is written, the code writing controller sets the remaining labels to be unsuccessfully matched, then the code writing controller verifies the batch of labels until the codes of all the labels are written, and the design is the sixth technical characteristic of the invention. The purpose of this design is: when the number of the tags read by the RFID reader-writer group through the group reading controller is larger than a set value, the tag is written by the code writing controller in batches, so that the efficiency of reading and writing the codes by the group reading controller can be improved, and the effective batch code writing speed of the tags can be further improved; in addition, the code writing controller writes the codes to the labels quickly and quantitatively during first-time code writing, the labels with excellent performance can be written into the codes quickly and successfully during quick code writing, the labels with relatively weaker performance are concentrated on the code writing in the later batch, the code writing speed can be relatively slower at the moment, and the labels with relatively weaker performance can be conveniently and effectively written into the codes, so that the writing rate of effective writing is improved, and meanwhile, the operation requirements of the code writing controller can be effectively reduced through batch code writing.

Detailed Description

Example 1: reference is made to figure 1. A method for batch code writing by using an RFID group reading technology comprises the following steps: firstly, a file containing an initial EPC code is led into a code writing controller, the content of the led file is stored in a cache and displayed in a plurality of linked list forms by the code writing controller, the file of the EPC code (including the requirements of a USER area, locking, encryption and the like) of a label needing code writing is led into a batch code writing software system, or the file needing code writing is self-generated by the batch code writing software system, and the content is stored in a system cache and displayed in a plurality of linked list forms; secondly, the code writing controller performs full detection and counting on the labels needing code writing through a group reading RFID reader-writer to realize group reading of the labels, when the label group reading controller is used, the labels can be placed into a group reading box in a quantity of 100 to 500 (for coiled labels, the quantity is preferably about 100 and 200), and the winding diameter of the labels is dispersed to weaken the influence between the labels; and step three, the code writing controller randomly captures the initial EPC codes matched with the number of the tags which are read by the group in the plurality of linked lists and exchanges the initial EPC codes in the linked lists with the EPC codes of the tags which are read by the group, so that the tag batch code writing operation is realized, the reading rate of the group reading RFID reader-writer is realized, generally 10S can read 1000 tags, the time for writing the codes of all the tags once can be generally finished within 30S, and the code writing can be finished within 1-2 minutes by repeating and circulating the code writing for many times (2-4 times). The code writing controller can be a control computer, and the control computer is a computer provided with a batch code writing software system.

The code writing controller is provided with a verification unit, the EPC codes in the labels read by the group reading RFID reader-writer are stored in the chain table to be detected in the verification unit after batch code writing of the labels is completed, the EPC codes in the chain table to be detected and the initially written EPC codes in the cache chain table are circularly matched by the code writing controller, the information of the labels which are unsuccessfully matched can be displayed by the code writing controller through a display interface, namely the EPC codes of the labels which are completed by code writing are automatically stored in the chain table to be detected, a detection function is started in a verification state link, whether the EPC codes in the circular detection chain table exist in the original chain table (hereinafter referred to as data matching) or not is detected, a state machine is updated after successful matching, and label data which are unsuccessfully matched are displayed in a software system interface list. In the cycle matching process, when the number of the labels which cannot be successfully matched is less than or equal to the set number, the code writing controller performs countdown number matching on the labels (when the number of the labels which cannot be successfully matched is less than or equal to 5, the code writing controller continuously performs 3-4 times matching on the labels which cannot be successfully matched), and when the countdown number is over, the labels which cannot be successfully matched are judged to be damaged, and code writing cannot be realized.

When the EPC code of the label which cannot be written is displayed on the display interface, the whole label is divided into two groups, then the code writing controller sequentially carries out group reading on the two groups of labels through the group reading RFID reader-writer, when the group reads out the EPC code of the label which comprises the label which cannot be written, the group of labels is divided into two parts, then the code writing controller sequentially carries out group reading on the two parts of labels through the group reading RFID reader-writer, the searching range is sequentially reduced, and the primary screening of the damaged label is realized. After the whole tag is searched for by two for multiple times, a small amount of good and weed mixed tags are read one by using an RFID reader-writer to realize accurate searching, namely, the searching range is narrowed by searching for two for multiple times, and then the bad tags are read on a common reader-writer to be found out.

The principle of binary search is to reduce the distance between the start position (front) and the end position (end), calculate the middle position mid = (front + end)/2, search in front and mid or mid and end, determine and reduce the search range, and finally determine the target. The method is controlled according to the qualification rate of normal RFID label production, the maximum probability of unsuccessful code writing is below 0.5 percent when the label with qualified reading performance is completely inspected in the first step, and the whole working efficiency is hardly influenced by the process of finding out the bad label through binary search.

When the number of the labels read by the group reading RFID reader-writer group by the code writing controller is larger than a set value, the code writing controller writes the codes on the labels in batches; when the labels are written in batches, the label is quickly and quantitatively written by the code writing controller, after the label writing of the set number of labels is completed, the rest labels are set to be unsuccessfully matched by the code writing controller, and then the batch of labels are verified by the code writing controller; after the previous batch of labels are verified, if the number of the remaining labels is less than or equal to the set value, the code writing controller writes codes on the remaining labels in batches, then the code writing controller verifies the batch of labels, if the number of the remaining labels is greater than the set value, the code writing controller writes the labels in a rapid and quantitative mode, after the number of the set labels is written, the code writing controller sets the remaining labels to be unsuccessfully matched, and then the code writing controller verifies the batch of labels until the code writing of all the labels is completed. When the codes are written and checked in batches, the code writing controller can collect the label information which is not successfully matched in each batch, display the label information through the display interface and take the label information as the subsequent screening basis.

When 500 tags are read in a group and the set value is 300, the code writing controller firstly carries out fast quantitative code writing on the tags, namely code writing operation is carried out on 300 tags in all notes, the rest tags are automatically set to be unsuccessfully matched, and after the 300 tags are successfully written, the code writing controller verifies the batch of tags; after the 300 label code writing verification is completed, because the remaining 200 labels are less than the set value 300, the code writing controller performs batch code writing on the remaining labels, then the code writing controller performs verification on the batch labels, and the code writing controller can summarize the information of the unsuccessfully matched labels in each batch and then display the summarized information through a display interface.

When 500 tags are read in a group and the set value is 200, the code writing controller firstly carries out fast quantitative code writing on the tags, namely code writing operation is carried out on 200 tags in all notes, the rest tags are automatically set to be unsuccessfully matched, and after the 200 tags are successfully written, the code writing controller verifies the batch of tags; after the 200 tags are successfully written, the code writing controller checks the 300 tags which are used for writing codes in batches because the remaining 300 tags are larger than the set value of 200, namely, the code writing operation is carried out on 200 of the remaining 300 notebooks, the remaining 100 tags are automatically set to be unsuccessfully matched, and after the 200 tags are successfully written, the code writing controller checks the batch of tags; after the batch of label code writing verification is completed, because the remaining 100 labels are less than the set value 200, the code writing controller performs batch code writing on the remaining labels, and then the code writing controller verifies the 100 labels, and the code writing controller can assemble the information of the unsuccessfully matched labels in each batch and then display the information through a display interface.
