Method and device for testing performance of rfid electronic tags

Abstract

A method and device for testing the performance of an RFID electronic tag proposed by the present invention, the detection method includes the following steps: a. Transmitting an activation signal to the electronic tag at a test distance S, receiving a response signal fed back by the electronic tag and obtaining the performance of the electronic tag b. compare the discrimination data with the preset reference data for determining the performance of the electronic tag; c. determine the performance of the electronic tag according to the comparison result of the discrimination data and the preset data; through the test RFID disclosed by the present invention The method and device for the performance of the electronic tag can detect the performance of the electronic tag, accurately judge the performance of the electronic tag, prevent management loopholes caused by the inability to read the information of the electronic tag installed on the vehicle, and the testing method is simple and efficient.

Description

technical field [0001] The invention relates to a testing method, in particular to a method and a device for testing the performance of an RFID electronic tag. Background technique [0002] In the field of intelligent transportation, the use of intelligent radio frequency identification (RFID) technology to collect traffic information has been widely used. The formed electronic tag (RF card) is then installed with a reader at each pre-arranged road point. The reader generates an electromagnetic signal and transmits it to the passive electronic tag at a certain power through the read-write antenna. The tag antenna of the passive electronic tag After receiving the signal and being activated, the electronic tag (radio frequency card) is activated and feeds back the vehicle information stored in the radio frequency card to the reader in the form of an electromagnetic signal, and the reader obtains the vehicle information through demodulation and other processing processes; becau...

[0002] In the field of intelligent transportation, the use of intelligent radio frequency identification (RFID) technology to collect traffic information has been widely used. The formed electronic tag (RF card) is then installed with a reader at each pre-arranged road point. The reader generates an electromagnetic signal and transmits it to the passive electronic tag at a certain power through the read-write antenna. The tag antenna of the passive electronic tag After receiving the signal and being activated, the electronic tag (radio frequency card) is activated and feeds back the vehicle information stored in the radio frequency card to the reader in the form of an electromagnetic signal, and the reader obtains the vehicle information through demodulation and other processing processes; because When the electronic tags leave the factory, the performance of different batches of tags may be flawed. When the electronic tags are installed in the vehicle, factors such as extrusion and folding often occur during the installation process, which may easily cause damage to the radio frequency card. At present, there is no The method of quality inspection of the installed electronic tags, therefore, it is easy to cause the vehicle information to be unidentifiable, and it is easy to have management loopholes
