Problems solved by technology
Generally, if a tag can be recognized globally, it needs to be able to work on all frequencies, but because different countries have different definitions of the frequency used by RFID in the UHF band, for example, the United States is 902-928MHz, Europe is 860-868MHZ, Japan is 950 -956MHz, plus the material attached to the label resonates with the frequency of each country, which will cause the label to be unable to be read when the label is shipped from one country to another, and this depends on the performance or consistency of a single label It is difficult to test the cause of failure

The invention discloses an automatic test system and test method for material tag reading performances. The test system comprises a signal receiving and processing system, an anechoic chamber, an antenna, a movable platform, a tag and attach material. The signal receiving and processing system is connected to the antenna, the antenna and the movable platform are arranged in the anechoic chamber, the tag and the attach material are arranged on the movable platform, and the tag is connected with the antenna in a signal manner. By the aid of the automatic test system, automatic read can be realized, the manual operating process can be reduced, and a report can be generated finally; meanwhile, various attach materials can be switched automatically, and the detuning effect of the RFID tag on the attach material can be analyzed through data analysis.
Description
technical field [0001] The invention relates to the technical field of label performance testing, in particular to an automatic testing system and testing method for label reading performance before materials. Background technique [0002] At present, the antennas used in most RFID tags are resonant antennas, so when there are high dielectric materials near the antenna, their resonant frequency will change, which is an important reason for the failure of RFID tags. Generally, if a tag can be recognized globally, it needs to be able to work on all frequencies, but because different countries have different definitions of the frequency used by RFID in the UHF band, for example, the United States is 902-928MHz, Europe is 860-868MHZ, Japan is 950 -956MHz, plus the material attached to the label resonates with the frequency of each country, which will cause the label to be unable to be read when the label is shipped from one country to another, and this depends on the performance...
