Technical Field
[0001] The present invention relates to the technical field of RFID tags, in particular to an automatic function testing system for batch radio frequency identification (RFID) tags and a use method thereof. Background Art
[0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology (hereinafter referred to as RFID technology) that uses radio frequency identification (RFID) communication. Its tags have the characteristics of small size, large capacity, long life, and reusability. They can support fast reading and writing, non-visual identification, mobile identification, multi-target identification, positioning and long-term tracking management. As a high-tech technology that processes information quickly, timely and accurately and the basis of information standardization, RFID technology is listed as one of the top ten important technologies in the 21st century. After using RFID tags, each item will have a unique "ID card". RFID technology can be applied to various industries such as production, retail, logistics, manufacturing, transportation, and public information services through the unique and effective identification of physical objects (including retail goods, logistics units, containers, freight packaging, production parts, etc.), which can greatly improve management and operation efficiency and reduce costs. Radio Frequency Identification (RFID) tags have been used in manufacturing, logistics, medical care, transportation, retail and other fields, and currently have a good market prospect. Therefore, it is becoming more and more important to carry out comprehensive functional verification of label products and ensure the quality of radio frequency identification (RFID) tags.
[0003] At present, when testing common functions such as reading and writing memory areas of multiple radio frequency identification (RFID) tags, it is easy to miss reading and writing, or read and write errors when reading and writing multiple tags together. Therefore, it is usually necessary to manually place a tag in the test area for reading and writing, then move the tested tag out of the test area, and manually put in the next tag to continue testing. This test method is very inefficient for large quantities of rolls of tags (hundreds or thousands of tags in a roll). Summary of the invention
[0004] The object of the present invention is to provide a batch radio frequency identification (RFID) tag automatic function test system and use method, which can realize rapid and automatic function test of large quantities of rolled radio frequency identification (RFID) tags and improve work efficiency.
[0005] To achieve the above object, the present invention provides the following technical solution: a batch radio frequency identification RFID tag automatic function test system, characterized in that the system comprises:
[0006] A host computer, wherein the host computer includes a processor and an operating system, and provides computing power and controls the radio frequency signal transceiver;
[0007] RF signal transceiver, which realizes the generation, reception and analysis of RF signals;
[0008] Circulator, which realizes directional transmission of radio frequency signals;
[0009] The near-field transceiver antenna can transmit radio frequency signals and receive tag response signals. The near-field transceiver antenna can only receive the response signal of the tag closest to it, thereby realizing one-to-one identification of rolled batch tags.
[0010] The left automatic rewinder and the right automatic rewinder can realize the automatic unwinding and rewinding of rolled batch labels, and the unwinding and rewinding are adjustable in both directions;
[0011] The base is used to fix and integrate the left automatic rewinder, the right automatic rewinder and the near-field transceiver antenna;
[0012] The test software controls the RF signal transceiver to implement the testing of the tag inventory, the tag reading memory area function, and the tag writing memory area function.
[0013] Furthermore, the left automatic rewinder and the right automatic rewinder can load labels with a width of 25 to 76 mm; the maximum rewind diameter is 185 mm, the core size is 1 to 3 inches, and the rewind speed ranges from 0 to 8 inches / second.
[0014] Furthermore, the inventory function test is further as follows: press the "Start" button, the RF signal transceiver sends an inventory instruction through the near-field integrated transceiver antenna, and determines whether the tag returns an EPC signal. If not, determine whether the "Stop" button is pressed. If returned, fill the tag EPC into the "Tag Identification" column of the test result and determine whether the "Stop" button is pressed. If not, resend the inventory instruction. If pressed, end the inventory function test.
[0015] Furthermore, the tag reading memory area function test is further as follows: press the "Start" button, the RF signal transceiver sends an inventory instruction through the near-field integrated transceiver antenna, and determines whether the tag returns the EPC signal. If not, the inventory instruction is resent. If it is returned, the tag EPC is filled in the "Tag Identification" column of the test result, and a read instruction is sent to determine whether the tag returns the data in the memory area. If not, fill in "NO" in the "Read Successful" column, and determine whether the "Stop" button is pressed. If it is returned, fill in the read data and test parameters in the corresponding column of the test result, and fill in "YES" in the "Read Successful" column, and determine whether the "Stop" button is pressed. If not, the inventory and read instructions are resent. If it is pressed, the tag reading memory area function test is ended.
[0016] Furthermore, the tag write memory area function test is further as follows: press the "Start" button, the RF signal transceiver sends an inventory instruction through the near-field transceiver antenna, and determines whether the tag returns an EPC signal. If not, the inventory instruction is resent. If so, the tag EPC is filled in the "Tag Identification" column of the test result, and then the write instruction is sent to determine whether the tag writes the memory area successfully. If not, fill in "NO" in the "Write Successful" column, and determine whether the "Stop" button is pressed. If successful, fill in the write data and test parameters in the corresponding column of the test result, and fill in "YES" in the "Write Successful" column, and determine whether the "Stop" button is pressed.
