The RFID reader-writer testing device provided by the embodiment of the application can be used for testing the tag reading capacity of the RFID reader-writer, particularly the capacity of simultaneously reading multiple tags. The RFID (Radio Frequency Identification) is one of automatic Identification technologies, and performs non-contact bidirectional data communication in a Radio Frequency manner, and reads and writes a recording medium (an electronic tag or a Radio Frequency card) in a Radio Frequency manner, thereby achieving the purposes of identifying a target and exchanging data. At present, the application field of RFID has been related to various aspects of people's daily life, including logistics, transportation, agriculture, animal husbandry, fishery, medical industry, manufacturing industry, document management, access control management, and the like. With the application field of the RFID becoming wider and wider, the application scenarios of the RFID reader are also becoming more complex, and often one RFID reader needs to read information of multiple electronic tags at the same time, so the testing of the multi-tag reading performance of the RFID reader is also becoming more and more important. In the related art, when the multi-tag reading performance of the RFID reader is tested, the comparability of the test result is often low due to changes in the tag distribution, the test environment, and other factors.
Based on this, the application provides an RFID reader testing device and an RFID reader testing method, which can keep the test environment fixed by standardizing the distribution of the reference tags in the test panel, and improve the contrast of the test result.
Some embodiments, referring to fig. 1 and 2, the RFID reader testing device includes: the RFID reader-writer antenna test system comprises a base 100, an antenna support 200 and a test panel 300, wherein the antenna support 200 is arranged at one end of the base 100, and the antenna support 200 is used for fixing an antenna of an RFID reader-writer to be tested; the test panel 300 is disposed at the other end of the base 100, the test panel 300 includes at least one test board 310, each test board 310 is provided with a plurality of reference tags 320, the reference tags 320 are arranged at equal intervals, and the reference tags 320 are used for the RFID reader to perform a multi-tag reading test.
The RFID reader-writer of the embodiment of the application can be an all-in-one machine with an antenna or a split machine externally connected with the antenna. The integrated RFID reader-writer with the antenna is usually a portable reader-writer, has small volume and can be directly fixed on an antenna test frame during test. And the split type RFID reader-writer externally connected with the antenna is usually a large reader-writer with a larger volume and is used in more complex scenes. During testing, the antenna of the reader-writer is fixed on the antenna bracket 200 and electrically connected with the reader-writer through a connecting wire.
The reference tag 320 is a tag having a substantially identical identifiable distance. When mounted on the test board 310, it needs to be detected by the tag tester, and if the identifiability of the tag is changed, the tag needs to be replaced by another tag. Reference tags 320 are regularly mounted on test board 310, and are usually arranged in a matrix type at equal intervals to ensure that the arrangement of reference tags 320 does not affect the test result. After the reference tag 320 is installed, the reference tag 320 needs to be encoded according to the position, and the encoded information is written into the corresponding reference tag 320.
Before testing, the RFID reader-writer needs to be connected with the control equipment, and working parameters of the RFID reader-writer are configured. During testing, the RFID reader reads the information of all the reference tags 320 of the test panel 300 through the antenna, and the performance of the reader under the current working parameters can be determined according to the number of the read tag information. The RFID reader-writer testing device provided by the embodiment of the application is a device with fixed environmental characteristics, the testing result has obvious comparability, and qualitative and quantitative performance tests can be performed on different types of readers-writers under different working parameter settings.
The RFID reader-writer testing device of the embodiment of the application has the following beneficial effects at least: by standardizing the distribution of the reference labels 320 in the test panel 300, the test environment can be kept fixed, and the comparability of the test results can be improved.
In some embodiments, each test board 310 has a plurality of mounting slots, and each mounting slot is used for fixing a corresponding reference tag 320. In one embodiment, the test board 310 may not have a mounting slot, and the reference labels 320 are arranged on the test board 310 by means of adhesion.
In some embodiments, referring to fig. 1, the test panel 300 includes a plurality of test boards 310, and the distances between adjacent test boards 310 are the same. It can be understood that the equidistant arrangement of the plurality of test boards 310 is beneficial to keeping the test environment relatively fixed, and avoiding the test error caused by the arrangement position of the test boards 310.

Materials having a significant attenuation effect on RFID signals include metal materials such as copper and iron. In this embodiment, the test board 310 made of a material having an attenuation effect on the RFID signal may simulate a signal shielding situation existing in a part of application scenarios, so as to obtain a test result closer to a real application scenario. In an exemplary embodiment, the test plate 310 may be made of plastic. Application scenarios with less shielding can be simulated at this time.
Some embodiments, referring to fig. 3, the RFID reader testing method is applied to the RFID reader testing apparatus in any one of the above embodiments, and the RFID reader testing method includes:
s100, configuring working parameters of the RFID reader-writer;
s200, controlling an RFID reader-writer to perform multi-label reading test;
s300, obtaining a reading result, and comparing the reading result with the standard data to obtain a test result.
For step S100, before the test, the RFID reader needs to be connected to the control device, and the working parameters of the RFID reader are configured. It can be understood that different working parameters correspond to different working states of the RFID reader, and reflect the hardware performance of the RFID reader.
For step S200, during the test, the RFID reader reads the information of all the reference tags 320 of the test panel 300 through the antenna at the same time. The reference tag 320 is a tag having a substantially identical identifiable distance. When mounted on the test board 310, it needs to be detected by the tag tester, and if the identifiability of the tag is changed, the tag needs to be replaced by another tag. Reference tags 320 are regularly mounted on test board 310, and are usually arranged in a matrix type at equal intervals to ensure that the arrangement of reference tags 320 does not affect the test result. After the reference tag 320 is installed, the reference tag 320 needs to be encoded according to the position, and the encoded information is written into the corresponding reference tag 320.
For step S300, after the test, the performance of the reader/writer under the current working parameters is determined according to the number of the read tag information. The reading result includes the number of successfully identified tags and the corresponding tag information, and the number of correctly identified tags and the corresponding tag information can be obtained by comparing the number with the preset reference tag 320 information. The performance of the RFID reader in the current state can be calculated according to the preset number of the reference tags 320, the number of the tags successfully identified, and the number of the tags correctly identified.
The RFID reader-writer testing method of the embodiment of the application has the following beneficial effects: the RFID reader-writer testing device with the standard tags 320 distributed in the standard mode is used for testing, so that the testing environment can be kept fixed, and the comparability of the testing result is improved.
Some embodiments, referring to fig. 4, before the step of configuring the corresponding parameters of the RFID reader, the method further includes:
s400, detecting the maximum identifiable distance of the RFID label;
s500, the RFID tags having the same maximum recognizable distance are used as the reference tags 320.
For steps S400 and S500, the reference tag 320 is a tag having substantially the same identifiable distance. When mounted on the test board 310, it needs to be detected by the tag tester, and if the identifiability of the tag is changed, the tag needs to be replaced by another tag. Reference tags 320 are regularly mounted on test board 310, and are usually arranged in a matrix type at equal intervals to ensure that the arrangement of reference tags 320 does not affect the test result. After the reference tag 320 is installed, the reference tag 320 needs to be encoded according to the position, and the encoded information is written into the corresponding reference tag 320.
In some embodiments, the operating parameters include operating power and read time. The working power is the running power of the RFID reader-writer. The reading time is the maximum time for allowing the RFID reader-writer to read a label, and if the information in the label is still not read after the maximum time is exceeded, the label is abandoned to be read.
In some embodiments, the read result includes a read rate and an identification ratio. The reading rate is the ratio of the number of successfully identified tags to the testing time, and the identification ratio is the ratio of the number of successfully identified tags to the total number of reference tags 320. The performance of the RFID reader-writer identification label under the current working parameters can be obtained through the reading rate and the identification proportion.
In some embodiments, the standard data includes theoretical data and preset data. The theoretical data is the accuracy and the recognition proportion of the RFID reader-writer for correctly recognizing the label under the ideal condition, and the preset data is the accuracy and the recognition proportion of the RFID reader-writer which meets the requirements of standard products for correctly recognizing the label. By comparing the reading result with the standard data, the performance of the currently tested RFID reader-writer can be judged to be up to the standard.
