Description
Technical field
The relevant non-directional induced intelligent card of a kind of RFID of the utility model, especially refer to a kind of 3D antenna device arrangement design, its primary structure design is after finishing with the planar antenna coiling, with series connection, parallel way, plane formula tradition coiled antenna coil can be connected into triangle cone or hexagonal pyramid 3D antenna structure, make the magnetic line of force that this kind 3D antenna structure can launch with the card reader antenna coil produce electric current to wake the work of IC crystal up near the cutting at 90 ° of angles with any direction, to obtain maximum induction electric energy and information, responding to not, the recipient designs to the non-directional induced intelligent card of the RFID of restriction.
Background technology
RFID (wireless identification system) is invention before more than 60 year, just emerging during the nearly last ten years a kind of identification system, RFID is different from traditional two-dimensional bar code tag system, its maximum characteristics are in (A) RFID smart card IC to be arranged, do not need self-powered, tool is compact, logical calculated and can store advantages such as high capacity information.(B) need not to contact card reader, do not wear and tear, not dirty and extremely fast the read-write advantage.(C) can repeat advantages such as input data and life-span be permanent.Therefore the RFID induction recognition system is all used in traffic such as in recent years, gate inhibition, customer identification, medical treatment, animal, goods logistics etc. on a large scale.
In the general RFID smart card self IC is arranged, but not self-powered.Yes in the boundary of corresponding card reader, smart card self antenna is launched magnetic line of force inductive energy from the card reader antenna coil, see through the exclusive charging system of smart card self, when charging to enough voltage successively, waking IC up starts working, to reach smart card and card reader interaction, finish identification mission.
And the exchange of magnetoelectricity or electromagnetism, at physical law, be must smart card antenna is coil-induced in boundary to launch the magnetic line of force to the card reader antenna coil, must need directivity, when the magnetic line of force and antenna are 90 ° of angles, cutting is maximum, respond to best, the energy conversion maximum, otherwise during less than 0 ° of angle, do not cut, do not respond to, energy is not changed.
Therefore, traditional type smart card 8 all is 4 two parallel aerial coils 41 of smart card 8 and card reader at present, 81 near the time, just maximum induction electric energy and information can be arranged, and that card reader 4 has is self-powered, therefore card reader 4 aerial coils 41 are to launch the magnetic line of force 411, and the magnetic line of force launched 411 and self aerial coil 41 to be the width of cloth at 90 ° of angles penetrate, therefore if smart card 8 aerial coils 81 are parallel with 41 one-tenths of card reader 4 aerial coils when close, naturally the magnetic line of force 411 that can be penetrated by card reader 4 aerial coils 41 width of cloth is also with the cutting at 90 ° of angles, to obtain maximum induction, wake 82 work (as Figure 11 and shown in Figure 12) of IC crystal up.Otherwise, when smart card 8 aerial coils 81 if vertical when close with 41 one-tenths of card reader 4 aerial coils, can't be by of the cutting of the magnetic line of force 411 of card reader 4 aerial coils 41 width of cloth ejaculation with 90 ° of angles, and do not produce induction, can't wake 82 work (as Figure 13 and shown in Figure 14) of IC crystal up, therefore, traditional type smart card 8 must be parallel near producing induction with 41 one-tenth of card reader 4 aerial coils when using, and is restricted and it is used and use all.
