The testing system includes a signal transceiving and processing system, an anechoic chamber, an antenna, a mobile platform, a label and an adhesive material. The signal transceiving and processing system is connected with the antenna; the antenna and the mobile platform are arranged in the anechoic chamber; the label and the adhesive material are arranged on the mobile platform; and the label and the antenna are in signal connection. The automatic reading performance testing system of the label before the material automatically reads, reduces the manual operation process, generates the final report, and at the same time carries out the data analysis of the multiple automatic switching adhesive material and of the detuning effect of the RFID label on the adhesive material.
Description
Technical field
The utility model relates to the technical field of tag performance test, particularly label reading performance Auto-Test System before a kind of material.
Background technology
At present, most of RFID label antenna used is resonant antenna, so while there is high dielectric material near antenna, their resonance frequency can change, this is that the major reason losing efficacy occurs RFID label.If a common label can be approved by the whole world, it need to can both work in all frequencies, but because country variant is different for the RFID frequency of utilization definition of uhf band, for example the U.S. is 902-928MHz, Europe is 860-868MHZ, Japan is 950-956MHz, add the frequency generation resonance of the attached material of label note and every country, when can cause adhesive label to transport to another one country from a country, label can not be read, and this is from single tag performance or the more difficult failure cause that reflects of uniformity test.
Utility model content
The purpose of this utility model is that the shortcoming that overcomes prior art, with not enough, provides a kind of material front label reading performance Auto-Test System.
The different frequency response condition of RFID label before the different attachment material of this test macro automatically testing, thus can be good at analyzing the off-resonance effect of antenna, for application and the better antenna of RFID label design of certain material provide guidance.
In order to achieve the above object, the utility model is by the following technical solutions:
Label reading performance Auto-Test System before material of the present utility model, comprise signal transmitting and receiving and disposal system, anechoic chamber,, antenna, moveable platform, label and attachment material, described signal transceiver is connected with antenna, described antenna and moveable platform are arranged in anechoic chamber,, described label and attachment material are arranged on moveable platform, and described label is connected with aerial signal.
Preferably, described signal transmitting and receiving disposal system comprises interconnective UHF signal transceiver and UHF signal processor.
Preferably, described UHF signal transceiver comprises the first attenuator, frequency demultiplier, signal generator, frequency-booster and the second attenuator being linked in sequence.
Preferably, described UHF signal processor comprises amplifier and signal receiver, and described amplifier is connected with the second attenuator, and described signal receiver is connected with the first attenuator, and described amplifier is all connected with antenna with signal receiver.
Preferably, described label is RFID label.
The utility model has following advantage and effect with respect to prior art:
1, because when test decay and need at least carry out hundreds of time read operation, the utility model can accomplish that robotization reads, and minimizing manual operation process, finally produces form.
2, can be to the multiple patch material that automatically switches, and the off resonance effect on patch material is analyzed data analysis to RFID label.
, while can test analysis RFID label circulating in the world, there is the reason of off resonance phenomenon in 3, the conventional national frequency range of Test coverage.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1 and Figure 2, label reading performance Auto-Test System before the utility model material, comprise signal transmitting and receiving and disposal system, anechoic chamber,, dual-mode antenna, moveable platform, label and attachment material, described signal transceiver is connected with antenna, described antenna and moveable platform are arranged in anechoic chamber,, and described label and attachment material are arranged on moveable platform, and described label is connected with aerial signal, in the present embodiment, described label is RFID label.
As shown in Figure 2, described signal transmitting and receiving disposal system comprises interconnective UHF signal transceiver and UHF signal processor.Described UHF signal transceiver comprises the first attenuator, frequency demultiplier, signal generator, frequency-booster and the second attenuator being linked in sequence.Described UHF signal processor comprises amplifier and signal receiver, and described amplifier is connected with the second attenuator, and described signal receiver is connected with the first attenuator, and described amplifier is all connected with antenna with signal receiver.
In the present embodiment, signal transmitting and receiving machine produces interrogating signal, and interrogating signal is risen to rf frequency, and the gain of control signal and decay, be down to IF-FRE by recovery signal, signal analysis output form.UHF signal processor inside is furnished with signal amplification and signal controlling, and fundamental purpose is signal to amplify and the acceptance of control signal to antenna.Testing process as shown in Figure 3, carry out hardware setting early stage, main signalization transmitting-receiving and disposal system emitting radio frequency signal frequency, test label to be tested and corresponding attachment material are installed simultaneously in corresponding screens, moveable platform can be controlled by computing machine in the position between label and attachment material.After hardware setting completes, carry out the calibration of the interior environment of anechoic chamber, and whole system, the intensity of truly receiving of exporting radio-frequency (RF) signal strength and the residing position of RFID label is approached as far as possible, get rid of environmental interference, simultaneously by calibration value Input Software.Obtain the laggard rower label of calibration value and open power test, now can, by the position of computer control attachment material and label, obtain the data that label is corresponding with opening power with the distance of attachment material.Finally by computing machine, automatically produce the data sheet of test, table 1 is output report tableau format, and tester can be analyzed by this data sheet the reason of RFID label off resonance.
