Erect the passage of space electromagnetic transmission by both coils between anti-counterfeit anti-theft label and the detection antenna.Electromagnetic coupled between anti-counterfeit anti-theft label and the detection antenna, promptly in-plant inductive coupling.In inductive coupling, the coil that detects antenna one side is equivalent to the primary coil of transformer, and anti-counterfeit anti-theft label one side's coil is equivalent to the secondary of transformer, thereby claims that also the inductive coupling mode is the transformer mode.The coupling intermediary of inductive coupling mode is a space magnetic field, and aerial coil is elementary to become the closed-loop path with ditch between the anti-counterfeit anti-theft tag coil is secondary to coupled magnetic field detecting.In the inductive coupling mode, detect antenna with radio-frequency (RF) energy be strapped in detect inductance coil around, by the coil magnetic field of alternation closure, link up the radio-frequency channel of detecting between aerial coil and the anti-counterfeit anti-theft tag coil.Detect a day alignment anti-counterfeit anti-theft label supply radio-frequency (RF) energy, for the anti-counterfeit anti-theft label, the required energy of its work is promptly by obtaining in this radio-frequency (RF) energy.The false proof robber's label of the utility model radio frequency will form behind the capacitive part folded turnover of coil middle part according to the electromagnetics principle.
Produce induction current when the coil of label enters the detection antenna magnetic field, this electric current produces magnetic field in the vertical direction of coil, and its intensity is:
N is the number of turn of coil in the formula; R is a radius, and X is the distance at vertical coil center.
Its magnetic flux phi and magnetic flux density B are:
Φ＝B*A＝μH A
Wherein, B=μ H, A are that coil gets area; H is a magnetic field intensity.
The magnetic field that can be got the coil generation by the aforementioned calculation formula is relevant with the magnetic flux that passes through, promptly relevant with area.Capacitive part upwards after the upset, is increased the useful area of coil, increased the magnetic flux of coil, strengthened the induction current in the coil, the sensitivity that has improved coil.Simultaneously, owing to turning on the electric capacity and coil generation coupling capacitance, increased electric capacity and caused label frequency to descend.
The utility model has carried out measuring with the anti-counterfeit anti-theft label among the embodiment to sensitivity, and its experimental technique and experimental result are as follows::
With reference to Fig. 7 and Fig. 8, width M=1m between emitting antenna TX and the receiving antenna RX, at emitting antenna TX and receiving antenna RX outside A, B is a test scale M parallel to the ground, the height h on M and ground is 1.2m, do at the 1/2M place one parallel to the ground and form a T shape test scale perpendicular to the scale C of M.Emissive power and receiving gain are definite value, and the frequency of emitting antenna is consistent with the frequency of label.
Label D is vertical with the ground direction, and along the C line of T shape graticule, slowly approaching to the M line, when reporting to the police, receiving antenna notes the distance L of label apart from the M line, and with the alarm distance record before and after the same label upset, it is as follows promptly to obtain experimental data:
| Frequency (Hz) before folding | Distance of reaction L (cm) before folding | Folding back frequency (Hz) | Folding back distance of reaction L (cm) | |
| 1 | 8.37 | 0 | 8.19 | 8.5 |
| 2 | 8.34 | 0 | 7.92 | 3.5 |
| 3 | 8.28 | 1 | 8.11 | 9 |
| 4 | 8.36 | 0 | 7.91 | 3.3 |
| 5 | 8.30 | 5 | 8.18 | 8.5 |
As seen, under emissive power and the immovable condition of receiving gain, the technology of the upset by capacitor plate just can make the sensitivity of label improve greatly.
The following describes using and anti-characteristics of bringing back to life of anti-counterfeit anti-theft label.
Adopt metallic gasket 4 that multiple mode can be arranged.In an embodiment of the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life, metallic gasket 4 is the circular gasket of diameter 5mm, and the optimum range of its diameter is 4-8mm.
In other embodiment of the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life, metallic gasket 4 is the annular gasket of diameter 5mm, and interior circular diameter is 2mm.The optimum range of its outside diameter is 4-8mm, and the optimum range of interior circular diameter is 2-6mm.
In other embodiment of the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life, metallic gasket 4 can also be the square washer of length of side 5mm, and the optimum range of its length of side is 4-8mm.
In other embodiment of the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life, metallic gasket 4 can also be the square ring plate of length of side 5mm, and internal circle is long to be 2mm.The optimum range of its outer shroud length of side is 4-8mm, and the optimum range of the interior ring length of side is 2-6mm.
In other embodiment of the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life, metallic gasket 4 can also be triangle " △ " or pentagon " ☆ " or the hexagon of 2-6mm for the length of side
Or octagon
Etc. the pad of shape, to adapt to different design requirements.
As in the electromagnetic field that microcircuit is positioned over f=8.2MHz the time,, can cause the action of receiving circuit because the mutual conversion of electric energy, magnetic energy will have oscillator signal output.
Under normal circumstances, the utility model high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life are provided by manufacturer, if genuine piece, commodity can be pasted the anti-counterfeit anti-theft label.When its product when the hand-held detector, just can determine its true and false: have sound and light alarm for true, otherwise then be vacation.Because the fixing code-point of separating is arranged on electric capacity, because the polar plate spacing of separating code-point will make the damage of thin-film capacitor irreversible for less than 30 microns in case puncture, so high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life are disposable, when detecting with hand-held detector again, no longer include any reaction.Thereby the commodity packaging that can stop protected stickup high sensitivity and the anti-anti-counterfeit anti-theft label that brings back to life is reused, and the packing of these commodity will can not be used to reclaim false making, to protect the authenticity of these commodity.
Yet,, separate code-point 8 and be subjected to external force and do the time spent because the label quality is pliable and tough, such as the label that is installed in book cover or leather shoes bottom surface, in use, because the effect that is subjected to rubbing repeatedly, might be activated conducting again, promptly label is brought back to life, and this can cause reusing of label.For example, for overcoming the above problems, with reference to Fig. 1, Fig. 3 and Fig. 4, code-point 8 places that separate between top layer and basalis are provided with metallic gasket 4.Like this, do the time spent,, separate code-point 8 and also be difficult for being reconnected conducting, label is no longer brought back to life owing to be subjected to the protection of metallic gasket 4 even label is subjected to external force.
To the metallic gasket that optimum thickness is the 30-100 micron be set in the position of separating code-point, guarantee that bringing back to life and being reused can not appear in Commercial goods labels, compare with the insulating rigid non-metallic gasket that uses in the prior art, outward appearance and the anti-crypticity that brings back to life of label also are improved, greatly improve result of use, obtained gratifying effect.
