Abstract
The utility model discloses a non - connects card resonant frequency to mark detection instrument fast, a serial communication port, including main control unit, read/write module and isolation measured module, the signal output part of main control unit is connected to read/write module, and read/write module is connected with antenna coil, and the signal input part who keeps apart measured module connects antenna coil, and signal output part connects the main control unit. The utility model discloses a measurement gets into the coupling characteristic that a card and card reader antenna can be estimated in a change of back field intensity at the card to pick out the card that resonant frequency meets the requirements in view of the above, have simple quick advantage.
Description
Technical field
The utility model relates to and a kind of non-ly connects card resonance frequency Fast Calibration testing tool.
Background technology
Resonance frequency is the important parameter of card, directly has influence on compatibility and the readwrite performance of card, need in process of production a kind of can Fast Calibration card whether whether meet the instrument of frequency requirement qualified to detect card.
Utility model content
The purpose of this utility model is to provide a kind of and non-ly connects card resonance frequency Fast Calibration testing tool, the scope whether antenna resonant frequency for detecting the contactless smart card adopting identical chips conforms with the regulations.
For achieving the above object, the present invention takes following technical scheme:
One is non-connects card resonance frequency Fast Calibration testing tool, comprise main control unit, module for reading and writing and isolation measurement module, the signal output part of main control unit is connected to module for reading and writing, module for reading and writing is connected with aerial coil, the signal input part of isolation measurement module connects aerial coil, and signal output part connects main control unit.
The non-coupled characteristic of resonance frequency on card and card reader antenna connecing card antenna of the present utility model has critical impact, suitable resonance frequency can have higher coupled characteristic, card can get more energy from field, therefore the measuring voltage intensity of the satisfactory card of resonance frequency field when entering the scope of showing up can because significantly declining appears in the absorption of card, the coupled characteristic of card and card reader antenna can be estimated by measuring the change of field intensity after card enters field, and select the satisfactory card of resonance frequency accordingly, therefore, the utility model has simple and quick advantage.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Embodiment
