Description

RFID label writing method

Technical Field

The invention relates to the logistics industry, in particular to a method for writing an RFID tag used in the logistics industry.

Background

At present, each link of warehousing, transportation, sorting, delivery and the like in the logistics industry of China mainly depends on manual operation, and is time-consuming and labor-consuming. Not only the operation cost of express delivery is high, and quality of service is difficult to remain stable for a long time moreover, and the manpower is not enough and goods overstock scheduling problem appears very easily in the express delivery peak period.

In recent years, with the development of information technology, the logistics field is also applying new technology to digitalize and informationize to improve efficiency.

The logistics industry uses a bill of materials for the recording of information in order to uniquely mark goods for tracking, sorting, etc. The information on the express bill which is common in our lives usually includes sender information, recipient information, article types and the like, and the information logistics industry of the type is originally filled by senders and is printed by bill printers at present. In addition to this information, the sheet is also provided with coded information as its unique mark, initially a series of numbers, and with the development of technology, bar codes and two-dimensional codes are used as information carriers.

When registering and sorting goods, it is necessary to perform operations based on information such as the destination of the goods. In addition to manual sorting, which is time-consuming and labor-consuming, the current automated identification method is to acquire the information of the goods by identifying the bar code or two-dimensional code on the bill.

However, due to the particularity of the logistics industry, the goods information is recorded by using a bar code or a two-dimensional code, and the process of identifying the carrier in the manner has obvious limitations. For example, in the case of recognition, there is a demand for the posture of the cargo, and it is necessary to orient the barcode or the two-dimensional code on the cargo sheet in the direction in which the recognition device is located, so that correct recognition can be performed. If the goods are not placed in proper directions, the goods cannot be identified. In addition, if the bar code or the two-dimensional code is damaged or dirty, the failure of identification is also caused. Therefore, the efficiency of bill information identification in the logistics industry at the present stage needs to be improved.

For this reason, the logistics industry tries to use Radio Frequency Identification (Radio Frequency Identification, abbreviated as "RFID") technology to perform contactless bidirectional data communication in a Radio Frequency manner, and specifically, read and/or write information data to a recording medium (an electronic tag or a Radio Frequency card) in a Radio Frequency manner, so as to achieve the purpose of identifying a target and the purpose of data exchange.

The basis of the full intelligent processing of the logistics industry is to quickly identify each parcel, and the non-contact quick reading of the RFID technology can well meet the requirement. As long as the RFID label is in the communication range of the RFID reading and writing device, the RFID label can be identified and read and write information data no matter how the attitude of the goods package is and which direction the label faces.

In this regard, the use of RFID tags to record information on goods is far superior to bar codes and two-dimensional codes, and is easy to handle and has a high recognition rate.

Therefore, the logistics industry is expected to apply the RFID technology, for example, in the links of batch handover and check of goods, inventory of goods in a warehouse, track tracking of people, vehicles and objects in a field, and finding lost goods.

In order to use the data information in the RFID tag to perform operations such as sorting during the transportation of the goods, it is necessary to write information data into the RFID tag before the transportation (for example, at the time of receiving the goods or at the time of warehousing the goods), for example, in the waybill printing process, or after the waybill printing and before the transportation.

In the method of writing information data into the RFID tag, a solution of the prior art is to use a dedicated RFID sheet printer, and such a commercially available RFID sheet printer uses a sheet with an RFID tag to print the receipt information on the sheet and also to write information into the RFID tag attached to the sheet.

However, the integrated RFID surface sheet printer needs to be abandoned and purchased again, and the price of the integrated RFID surface sheet printer is expensive, which is too expensive for logistics enterprises. In addition to purchasing such RFID facer printers, a completely new warehouse management system needs to be replaced to support the associated functionality of the newly purchased integral RFID facer printer.

Thus, for logistics enterprises, instead of upgrading one machine, numerous machines requiring numerous logistics department or logistics warehouse are upgraded. Obviously, the integrated RFID surface single printer has huge investment in popularization and application, and relates to a plurality of systems, and for users, the fund required by the whole operation is too high, the time is long, and the effect is slow.

Although the RFID technology will greatly improve the logistics efficiency, the current RFID surface sheet printer has huge economic cost and high investment cost in the industry, and thus is not practically popularized and applied.

Preferably, according to the RFID tag writing method of the present invention, when it is determined that the verification is successful, the user is prompted that the RFID tag writing is successfully completed.

The operation object of the embodiment is a good on which information is printed on a bill, specifically, it is calculated that the good has the bill and a barcode, a two-dimensional code or a character is printed on the bill.

When goods enter the RFID detection area, the RFID tag writing method is started.

[ image acquisition step ]

The field of view is detected and the information carrier 211 (e.g. a bar code, a two-dimensional code or text) on the menu 21 is imaged, e.g. a photograph is taken, resulting in an acquired image.

[ information identification procedure ]

And identifying the acquired image to obtain data information.

[ RFID tag identification step ]

And after the data information is identified, scanning and reading the field of view.

If the tag response signal is not received, the RFID tag is judged to be absent, and the process is ended.

And if the RFID tag response signal is received, identifying the received tag response signal. Specifically, the method comprises the following steps: and judging whether the received response signal has only one legal response signal or not.

And if the result is yes, confirming that the only legal RFID label exists in the detection area, at the moment, writing the current RFID label into the checking error times for zero clearing, and sending the result of successful identification of the RFID label.

If a plurality of legal response signals exist, a plurality of legal RFID tags exist in the detection area, at the moment, the identification is judged to be failed, a prompt for outputting RFID tag collision is sent, and the process is ended.

[ RFID tag writing step ]

And after receiving the result that the RFID label is successfully identified, storing the data information obtained in the information identification step into a storage unit of the RFID label.

Through the above-described process, the data information written on the information carrier 211 on the sheet 21 is written in the RFID tag 212 of the sheet 21.

After such an operation, the sheet 21 on the goods carries two types of information, one is information of a bar code, a two-dimensional code or a character, and the other is information stored in the RFID tag.

When the goods enter the subsequent logistics transmission link, the information in the RFID label can be directly read by using the RFID reader-writer, and then the classification, the transfer and other operations are carried out according to the read information.

By the RFID label writing method, the use of the RFID label can be increased on the surface sheet processed by the existing surface sheet printer, and the RFID label is combined with the existing surface sheet printer for use. The use of the existing surface sheet printer is not abandoned, so that the cost of using the RFID label by a user is low, and the use of the RFID label is easily added to the actual use process.

When the bill 21 appears in the field of view of the image capturing module, the image capturing module 11 starts image capturing (for example, taking a photograph), and after the image is captured, the image capturing module 11 transmits the captured image to the information recognition module 12.

[ information recognition Module ]

The information identification module 12 is used for identifying the received image to obtain data information.

The information recognition module 12 has an input connected to the image acquisition module 11 and an output connected to the main control module 14.

The image from the image acquisition module 11 enters the information identification module 12 through the input end, the information identification module 12 starts image identification to obtain data information, and after the data information is successfully identified, the information identification module 12 transmits the identified data information to the main control module 14 through the output end.

[ RFID tag read/write Module ]

And the RFID tag read-write module 13 receives an instruction (for example, a read instruction or a write instruction) and data information from the main control module 14, and performs a read operation and a write operation on the RFID tag 212 in the detection area.

Specifically, the RFID tag read/write module 13 scans a detection field of view (detection area), receives a response signal from the RFID tag 212, and transmits data information from the main control module 14 to the RFID tag 212.

The tag identification unit 142 is used to confirm whether or not an RFID tag is present in the detection area and the RFID tag is a unique tag. That is, it is confirmed whether or not an RFID tag is present in the detection area. When receiving the RFID tag response signal sent from the RFID tag read/write module 13, the tag identification unit 142 determines whether the received response signal satisfies a specific condition, i.e., whether there is only one response signal, and if the result is "yes", it determines that there is a unique RFID tag in the detection area, and at this time, the tag identification unit 142 sends a result of successful RFID tag identification to the control unit 141. If the RFID tag response signal is not received or a plurality of response signals are received after the scanning, it is determined that there is no RFID tag or a plurality of RFID tags in the detection area, and at this time, the tag identification unit 142 transmits a result of the RFID tag identification failure to the control unit 141.

Step 1, the image acquisition module 11 automatically detects the field of view, and when the goods attached with the receipt 21 are placed in the field of view of the image acquisition module 11, the image acquisition module 11 performs image acquisition on the information carrier 211 (such as a bar code, a two-dimensional code or characters) on the receipt 21, such as taking a picture, to obtain an acquired image.

Step 2, the image acquisition module 11 sends the acquired image to the information identification module 12.

And 3, the information identification module 12 identifies the image to obtain data information.

In step 4, the information identification module 12 transmits the identified data information (e.g. the content of barcode/two-dimensional code/text) to the main control module 14.

And step 5, after receiving the content sent by the information identification module 12, the main control module 14 sends a reading instruction to the RFID tag reading and writing module 13.

And step 6, the RFID label reading and writing module 13 performs scanning and reading.

Step 7, if the RFID tag response signal is received, the RFID tag read/write module 13 sends the received tag response signal to the tag identification unit 142 of the main control module 14. If the tag response signal is not received, the RFID tag read-write module 13 outputs a prompt that the RFID tag does not exist to the human-computer interaction module 15, and the process is ended.

Step 8, the tag identification unit 142 determines whether there is only one legal response signal in response to the received response signal. And if the result is yes, determining that the only legal RFID label exists in the detection area, at this time, resetting the number of times of writing the current RFID label into the check error, and proceeding to the next step 9. If a plurality of legal response signals exist, a plurality of legal RFID tags exist in the detection area, at this time, the tag identification unit 142 judges that the identification fails, sends a prompt to the human-computer interaction module 15, outputs a prompt of RFID tag collision, and ends the process.

In step 9, the tag identification unit 142 sends the result of successful RFID tag identification to the control unit 141 of the main control module 14.

Step 10, the control unit 141 of the main control module 14 sends a write instruction and written content to the RFID tag read-write module 13, where the written content is the data information of the barcode, the two-dimensional code, or the text identified in step 4.

Step 11, the RFID tag read/write module 13 sends a wireless signal including a write command and data information to the RFID tag 212 of the bill

In step 12, after the RFID tag 212 receives the write command, it stores the received data information in the tag storage unit.

In step 13, the RFID tag 212 sends a written wireless signal to the RFID tag read/write module 13.
