Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the smart card architecture schematic diagram of the present invention；
Fig. 2 is the structural representation of smart card Preparation equipment.
Embodiment
The present invention provides a kind of smart card of fixed frequency, as shown in figure 1, the smart card 5 include intelligent card chip 1,
Capacitor 2 and inductance coil 3, wherein, capacitor 2 and the composition LC resonance circuits of inductance coil 3, inductance coil 3 are internally provided with
Bar magnet 4.
The preparation method of above-mentioned smart card 5 is as follows：A, inductance coil 3 is turned to using conductive filament, by inductance coil 3 and electricity
After container 2, intelligent card chip 1 are connected, smart card 5 is constituted；B, the sense that step a smart card 5 is placed on to frequency measuring instrument 6
Answer in coil 7, and mobilizable bar magnet 4 is placed in the coil of inductance coil 3, as shown in Figure 2；C, frequency measuring instrument 6 lead to
Cross the frequency for inductively measuring smart card 5 and be compared with preset value, the connection pusher 9 of frequency measuring instrument 6, pusher
9 movement bar magnets 4 change the frequency of smart card 5；D, when the frequency of smart card 5 reaches preset value, pusher 9 stop push,
Keep bar magnet 4 constant with respect to the position of inductance coil 3, and being sticked in bar magnet 4 using glue makes it fix not on inductance coil 3
Relative displacement is produced again, that is, obtains the smart card 5 that frequency is fixed on preset value.
In above-mentioned steps d, bar magnet 4 can also be fixed on inductance coil 3 by the way of spot welding.
Reference picture 2, present invention also offers a kind of equipment of fixed smart card frequency, including for detecting intelligent card
The frequency measuring instrument 6 of 5 frequencies, and for moving the pusher 9 of bar magnet 4.The frequency measuring instrument 6 includes being used to feel
Should detect can be according to reality in the induction coil 7 of the frequency of smart card 5, and the process chip 8 for process signal, process chip 8
Frequency values are set the need for production and use, for compared with the frequency values of smart card 5 of detection, making the frequency values of smart card 5 most
It is fixed on afterwards in set value range, it is preferred that when default frequency values is use in process chip 8 after smart card 5
Frequency input signal value, smart card 5 is constituted resonance with it.The pusher 9 includes pushing motor 10 and just to bar magnet 4
The push-rods 11 of setting, push the connection process chip 8 of motor 10.When smart card 5 is placed on induction coil 7, and bar magnet 4 is put into
When in inductance coil 3, push the driving of motor 10 push-rods 11 and move, it is slow to push bar magnet 4, change the frequency of smart card 5, work as intelligence
The frequency that 5 can be blocked reaches after the preset value in process chip 8 that process chip 8, which transmits a signal to push motor 10, makes it stop, magnetic
Rod 4 is rested on rearmost position, and bar magnet 4 is fixed on inductance coil 3 by the way of glue bonding by staff.
The first coiling inductance coil 3 of the smart card preparation method of the present invention simultaneously constitutes smart card 5, then be arranged on electricity by movement
Feel the bar magnet 4 in coil 3, adjust the frequency of smart card 5, reach preset value, after bar magnet 4 is fixed, obtained smart card 5
Frequency values are unified in resonance point range, greatly reduce defective work, and because parameter is unified, can meet the demand of user.
The preferred embodiments of the present invention are these are only, as long as realizing the technical side of the object of the invention with essentially identical means
