Description
Technical field
The utility model belongs to the REID field, is specifically related to a kind of radio-frequency (RF) identification comprehensive tester.
Background technology
A basic radio-frequency recognition system is made up of card reader, antenna and three parts of label.Traditional frequency spectrograph must be under the situation that holonomic system is arranged and can work, and just can obtain the performance that therebetween communication signal is analyzed card reader and label, can't measure under the imperfect or inoperable situation of system.
Every technical indicator of RF recognition card reader and label is decided by all kinds of protocol specifications, as ISO14443, and ISO18000 etc.The test event of different agreement is widely different, needs different equipment, the testing cost height.
Whether ISO has proposed how to test the uniformity test standard of protocol compliant simultaneously.In these standards specified in more detail card reader and label can operate as normal parameter variation range, but traditional card reader can not freely be adjusted all these adjustable parameters, therefore causes test not exclusively.
Second generation super high frequency radio frequency criterion of identification need be set up the microsecond level and reply communication in real time between transponder and label, traditional instrument can't reach this time requirement.
Summary of the invention
The purpose of this utility model be to propose a kind of do not rely on outside source, agreement cover wide, parameter testing comprehensively, realize the radio-frequency (RF) identification comprehensive tester of replying in real time.
The radio-frequency (RF) identification comprehensive tester that the utility model proposes is made up of controller 1, intermediate frequency, baseband processor 2, radio-frequency-up-converter 3, radio frequency down-conversion device 4, and its structure as shown in Figure 1.The output termination intermediate frequency of controller 1, the input end of baseband processor 2, the input end of the output termination radio-frequency-up-converter 3 of intermediate frequency, baseband processor 2, the output termination equipment under test of radio-frequency-up-converter 3, the input termination equipment under test of radio frequency down-conversion device 4, the output termination intermediate frequency of radio frequency down-conversion device 4, the input end of baseband processor 2.
The course of work of the present utility model is described below as shown in Figure 2:
The first step: initialization intermediate frequency, baseband processor 2, radio-frequency-up-converter 3 and radio frequency down-conversion device 4.
Second step: configuration intermediate frequency, baseband processor 2, radio-frequency-up-converter 3 and radio frequency down-conversion device 4 hardware parameters.
The 3rd step: the part signal data that generated by controller 1 are downloaded to intermediate frequency, baseband processor 2 and process processing generate complete output signal.
The 4th step: radio-frequency-up-converter 3 emitting radio frequency signals also have radio frequency down-conversion device 4 to receive the signal that equipment under test returns, and the data transmission after the down coversion is given intermediate frequency, baseband processor 2.
The 5th step: the data that controller 1 analysis intermediate frequency, baseband processor 2 provide generate test result.
This radio-frequency (RF) identification comprehensive tester is integrated, and radio frequency identification signal takes place and the radio frequency identification signal analytic function, possesses the radio-frequency (RF) identification agreement by software programming, can initiatively and between unit under test set up communication, be no longer dependent on extra read-write equipment and testing tool.
This radio-frequency (RF) identification comprehensive tester combines advanced modular instrument and software and radio technique, dirigibility and the self-defining characteristics of software with height, realized support at software layer to the many standards of radio-frequency (RF) identification, use same system just can test, broken through traditional instrument because the limitation of its proprietary hardware constraints to the radio-frequency (RF) identification product of different agreement.In software design, adopt modular hierarchical structure simultaneously, when realizing complicated algorithm, had interface succinct, standard again, can carry out secondary development, possessed the incomparable extensibility of traditional instrument.
This radio-frequency (RF) identification comprehensive tester has powerful software function, can be completely achieved agreement predetermined parameter range of adjustment, can carry out complete uniformity test to measured piece.
The hypervelocity processing capability in real time that this radio-frequency (RF) identification comprehensive tester adopts intermediate frequency, baseband processor plate to carry FPGA realizes replying in real time communication process in conjunction with real-time Processing Algorithm.
