Description
Technical field
The utility model relates to the card reader field, relates in particular to a kind of contactless card reader.
Background technology
Along with the development of mobile communication, mobile phone has become the necessity in people's life.On the other hand, the development of infotech, rapid economy development makes that the smart card in people's hand constantly increases, such as bank card, transportation card, work card, gate inhibition's card, accumulating card, member card or the like.The development of RFID technology let us life facility is got up, but to everyone so much card is arranged, and is but more or less individual not convenient.To the situation of above three aspects, released the integrated of various smart cards such as in mobile phone, realizing bank card, transportation card, work card in the market.Main scheme increases radio-frequency enabled, i.e. radio-frequency SIM card scheme exactly in SIM.
Because the radio-frequency enabled of radio-frequency SIM card scheme works in UHF or microwave frequency band; The radiofrequency signal of radiation has directive property and polarization characteristic; And present contactless card reader adopts the mode of an antenna usually, and defectives such as blind area, jitter are arranged when existing like Card Reader.The radiofrequency signal field pattern of radiation was different when main cause was that radio-frequency SIM card places different mobile; The same mobile phone that radio-frequency SIM card is housed also can produce different radiofrequency signal field patterns with different disposing ways; Changeable like this radiofrequency signal field pattern; For the card reader of having only an antenna, be difficult adaptation.In view of this, need provide a kind of novel card reader to address the above problem.
The utility model content
The utility model is a kind of contactless card reader that proposes for solving the problems of the technologies described above, and can adapt to changeable field shape, reaches Card Reader effect preferably.
The utility model solves described technical matters and can realize through following technical scheme: the contactless card reader of this patent; Comprise: master controller, connect and be controlled by the RF transceiver and the antenna gating switch of master controller and at least two the communication antenna that is connected in said antenna gating switch respectively, said master controller is selected communication antenna according to communication quality control antenna gating switch.
Preferably, said master controller according to said communication antenna can detect radio-frequency SIM card signal, or the signal strength values of said signal judge the quality of communication quality.
Preferably, said antenna gating switch is independent switch or switches set.
Preferably, said each communication antenna can be identical symmetrical or different, and its radio frequency model spatially points to difference.
Preferably, said communication antenna adopts the mode of time-sharing work.
Preferably, RF transceiver, communication antenna co-operation are in the frequency range of one of uhf band, 2.4GHz ISM or 5.8GHz ISM.
Owing on contactless card reader, used a plurality of positions or different communication antenna; Can produce different field shapes; Through judgement, come the communication antenna of contactless card reader is carried out optimum selection, in order to adapt to and the better radio-frequency SIM card that reads to signal quality.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done a detailed elaboration.
As shown in Figure 1, the contactless card reader of the utility model comprises master controller, RF transceiver, antenna gating switch and at least two communication antennas.
In this embodiment, at least two communication antennas can be following combination: (1) identical or symmetric communication antenna alignment becomes different orientation; (2) different communication antennas are arranged in identical orientation; (3) different communication antennas are arranged in different orientation.The spatial direction that more than is combined on the radio frequency model is different, can adjust according to the shape and the radiation pattern thereof of communication antenna, makes the field pattern of contactless card reader reach best.In this embodiment, the combined of above-mentioned communication antenna is worked with the mode of timesharing.
The antenna gating switch is connected between RF transceiver and the whole communication antenna, and connects and be controlled by master controller, according to the switching signal of master controller communication antenna is selected.In this embodiment, the antenna gating switch can be single switch, also can be switches set.
RF transceiver is connected in master controller and antenna gating switch, receives and add up through communication antenna to detect the signal of radio-frequency SIM card or the signal strength values of reception signal.
Master controller; Be connected in RF transceiver and antenna gating switch; Receive the signal can detect radio-frequency SIM card, or receive the signal strength information of signal through RF transceiver, judge whether communication quality is qualified, low excessively as if communication quality; Then send switching signal and give the antenna gating switch, communication antenna is selected.
In this embodiment, RF transceiver, communication antenna co-operation are in the frequency range of one of uhf band, 2.4GHz ISM or 5.8GHz ISM.
See also Fig. 2, be the working method process flow diagram of the contactless card reader of the utility model.
In steps A, contactless card reader carries out initialization.
In step B, the master controller of contactless card reader is through antenna gating switch acquiescence or select a communication antenna at random.
In step C, the signal that can RF transceiver statistics communication antenna detected radio-frequency SIM card, or the signal intensity of radio-frequency SIM card sent to master controller; Master controller judges in view of the above whether communication quality is qualified; If qualified, then get into step D, continue to use this antenna; If defective, then send switching signal and give the antenna gating switch, antenna is switched.
In this embodiment, master controller selects a communication antenna to carry out Card Reader earlier, judges then whether communication quality is good, if communication quality is relatively poor, selects an antenna to attempt so again; If communication quality is good, so ensuing communication continues to use this antenna.So realize to environment, to the comparatively suitable adaptation of different shapes of different cards, different mobile phones.
To a kind of contactless card reader of the utility model and Card Reader mode thereof, both can be used for the near field payment technical field; Also can be used for the medium and long distance field, such as brake, welcome gate inhibition, advertisement pushing etc.
Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection domain of the present invention.
