Description

A kind of non-contact IC card communication device
Technical field
The utility model relates to the magnetic card technique field, relates in particular to a kind of non-contact IC card communication device.
Background technology
Along with people exchange frequent day by day, money transaction is also more and more, people have to carry a large amount of cashes and carry out transaction.Because constant and latent all risks of depositing of carrying buckets of cash bring a lot of unnecessary troubles for people's daily routines, so various bank cards arise at the historic moment.Existing bank card mainly contains three kinds of non-contact IC card, magnetic stripe card and Contact Type Ic Cards.Wherein, most of non-contact IC card is mainly used in small amount payment or needs the field of simple authentication, for example is used for mass transit card, subway card, mess card and gate inhibition's card etc.
Non-contact IC card claims radio-frequency card again, is made up of IC chip, induction antenna, and the two is encapsulated in the PVC card of a standard, and chip and antenna do not have any exposed parts.Card (is generally 5-10mm) near the read write line surface, finishes the reading and writing operation of data by the transmission of radiowave in the certain distance scope.Non-contact IC card itself is passive body, when read write line when sticking into capable read-write operation, the signal that read write line sends is made up of two parts stack: a part is power supply signal, this signal by the clamping receipts after, produce resonance with the L/C of itself, produce a transient energy and supply with chip operation; Another part then is combined data signal, and commander's chip is finished data, modification, storage etc., and returns to read write line.
Existing non-contact IC card, the area that its coil centers on be than the undersized of card, thus general card reader in order to improve reliability, the induction region of card reader can be more a lot of greatly than the size of card, make card reader have very big volume.The non-contact card of a standard is of a size of 85.5mm * 54mm, and that existing scheme can't be done the size of card reader is little, so, increased card reader has been integrated into difficulty on the electronic equipment.Simultaneously, because card reader works in aggressive mode, so it need launch wireless signal when having detected card, this has just caused certain radiation pollution.In addition, contactless card reader can be reacted to the non-contact IC card in the 10cm, when having two or above non-contact IC card in effective range, can cause identification error or erroneous judgement.Therefore, existing non-contact IC card communication apparatus, it has the defective that size is big, radio pollutes and causes erroneous judgement easily.
The utility model content

Embodiment
Below in conjunction with drawings and Examples the utility model is done more detailed description.
The utility model discloses a kind of non-contact IC card communication device, as shown in Figure 1, it includes Non-contact Media Reader 10 and non-contact IC card 20, described Non-contact Media Reader 10 includes one and is the magnetic core 100 that the groove shape arranges, and described magnetic core 100 is gathered data on magnetic card by the field signal of arbitrary position of close four sides and position, four angles on the induction non-contact IC card 20.In the said structure, there is an electromagnetic field in the magnetic core 100, when swiping the card, the user only needs magnetic core 100 is inserted in arbitrary position of four sides of non-contact IC card 20 and position, four angles, make between non-contact IC card 20 and the magnetic core 100 and produce electromagnetic induction, magnetic core 100 is converted to the magnetic signal of sensing electric signal and feeds back to Non-contact Media Reader 10, thereby makes non-contact IC card 20 and magnetic core 100 successfully set up communication, and further does reading and writing and handle.In the said structure, since 100 of magnetic cores need on the induction non-contact IC card 20 than the zonule, make Non-contact Media Reader 10 compare the Non-contact Media Reader 10 of existing large-size, reduced its induction region, thereby further reduced the overall dimensions of product, the utility model can be integrated on other electronic equipments well.Simultaneously, because the magnetic core 100 of Non-contact Media Reader 10 is the setting of groove shape, so its induced field concentrates in the magnetic core 10, avoided the pollution of radio to environment.In addition, owing to only allow to insert a non-contact IC card 20 in the magnetic core 100, so, avoided sensing the erroneous judgement that many non-contact IC cards 20 cause because of Non-contact Media Reader 10, improved the accuracy of reading and writing data.Therefore, the utility model reduced equipment size, reduced that radio pollutes and the erroneous judgement of having avoided swiping the card.
In conjunction with Figure 1 and Figure 2, the two ends of magnetic core 100 are respectively the N utmost point and the S utmost point, and the N utmost point and the S utmost point are oppositely arranged, and form a groove to make magnetic core 100.Non-contact Media Reader 10 includes a noncontact communication chip 101 and an induction antenna 102, and this induction antenna 102 is wound in magnetic core 100 and its two ends all are connected in noncontact communication chip 101.When having electric current to flow in the induction antenna 102, to produce a magnetic field in the groove of magnetic core 100, at this moment, contactless IC card is inserted in the groove of magnetic core 100, the electromagnetic field that non-contact IC card 20 transmits by magnetic core 100, set up communication with noncontact communication chip 101, thereby operation such as realize reading, writing.
In the present embodiment, induction antenna 102 can be that enameled wire also can be the PCB antenna, still, this is a preferred embodiment of the present utility model, be not limited to the utility model, in other embodiment of the present utility model, induction antenna 102 can also be the wire rod of other types.
In the present embodiment, as shown in Figure 1, the recess width of magnetic core 100 is 2mm to 3mm, makes in this magnetic core 100 and can only insert a non-contact IC card 20, the erroneous judgement that causes to avoid many cards to insert simultaneously.But, in other embodiment of the present utility model, along with the change of non-contact IC card 20 thickness, the groove of magnetic core 100 correspondingly can also be set to other width, make the utility model can be applied to the non-contact IC card 20 of multiple size neatly.
As shown in Figure 3; non-contact IC card 20 includes first fender 200, second fender 201 and is arranged at insulated substrate 202 between the two; described insulated substrate 202 is provided with an IC-card coil 203 and an IC-card chip 204, and described IC-card coil 203 is connected in IC-card chip 204.This IC-card coil 203 arranges in the form of a ring along four sides of non-contact IC card 20 and position, four angles.
In the disclosed non-contact IC card communication device of the utility model, since 100 of magnetic cores need on the induction non-contact IC card 20 than the zonule, make Non-contact Media Reader 10 compare the Non-contact Media Reader 10 of existing large-size, reduced its induction region, thereby further reduced the overall dimensions of product, the utility model can be integrated on other electronic equipments well.Simultaneously, because the magnetic core 100 of Non-contact Media Reader 10 is the setting of groove shape, so its induced field concentrates in the magnetic core 10, avoided the pollution of radio to environment.In addition, owing to only allow to insert a non-contact IC card 20 in the magnetic core 100, so, avoided Non-contact Media Reader 10 because sensing the erroneous judgement that many non-contact IC cards 20 cause, improved the accuracy of reading and writing data.Therefore, the utility model reduced equipment size, reduced that radio pollutes and the erroneous judgement of having avoided swiping the card, captured Non-contact Media Reader 20 can't be integrated on other electronic equipments than hang-up, for applying of non-contact IC card communication device made outstanding contributions.
The above is the utility model preferred embodiment, is not limited to the utility model, all modifications of making in technical scope of the present utility model, is equal to and replaces or improvement etc., all should be included in the scope that the utility model protects.
