Background technology
Due to two kinds of standards of the audio interface of the equipment such as mobile phone, panel computer in without the standardization application stage, cause the card class read-write equipment production standard disunity derived for audio interface, the channel supply is loaded down with trivial details, and the terminal sale business obscures two kinds of standards, and the consumer uses the problems such as difficulty.
Existing product on the market at present, rest on single matching stage for two audio interface standards of planting of the equipment such as mobile phone, panel computer, can't realize the compatibility of single product to audio interface; Thereby cause realizing the compatibility of the card class read-write equipment realization of data interaction for two kinds of audio interface by audio interface.
The utility model content
Can not realize that the read-write equipment of the card class of data interaction realizes the compatibility deficiency for two kinds of audio interface by audio interface in order to overcome prior art, the purpose of this utility model is to provide a kind of the solution by audio interface to realize the card class read-write equipment of the card equipment of data interaction for the two kind standards of Intelligent Recognition audio interface of the compatibling problem of two kinds of audio interface.
To achieve these goals, the utility model solves the technical scheme that the problem of its technology takes and is:
A kind of card class read-write equipment based on the two kind standards of audio interface, comprise main control module;
The card class module for reading and writing be connected with described main control module;
Be connected with described main control module, have key, the safety chip for card information and clip pin are encrypted by key;
Be connected with described main control module, be converted to sound signal for the card information by after encrypting and clip pin and be converted to the audio conversion module of the steering order of identifying for described card class read-write equipment for consumption terminal identification the sound signal that will receive from consumption terminal;
With the earphone interface of consumption terminal, with described audio conversion module, be connected respectively, for the audio interface of the communication that realizes card class read-write equipment and consumption terminal;
The automatic identification module of two standard audio interfaces be connected with audio interface with described main control module.
Described card class module for reading and writing is for reading the contactless IC card read/write unit of contactless ic card information.
Described main control module is central processor CPU or microprocessor.
Described consumption mobile terminal is mobile phone, panel computer, PC or PDA.
The difference of the two kind standards of audio interface is that audio input interface is different from the interface of the ground wire position, the utility model utilizes the audio input interface voltage characteristic of the voltage of line interface above Ground, realize automatic identification function, and dock corresponding path, and then realize data interaction and operational applications function.
The beneficial effects of the utility model are, by the automatic identification module of two standard audio interfaces, realize compatible two audio interface standard of planting; This card class read-write equipment can read contactless IC card, and card class read-write equipment is connected with consumption terminals such as mobile phone, panel computer, PC or PDA, has realized consumer's can realize swiping the card order of payment whenever and wherever possible, has improved the convenience of consumption and payment.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
Shown in Fig. 1, a kind of card class read-write equipment based on the two kind standards of audio interface, comprising: main control module 1; The card class module for reading and writing 2 be connected with described main control module 1; Be connected with described main control module 1, have key, the safety chip 3 for card information and clip pin are encrypted by key; Be connected with described main control module 1, be converted to sound signal for the card information by after encrypting and clip pin and be converted to the audio conversion module 6 of the steering order of identifying for described card class read-write equipment for consumption terminal identification the sound signal that will receive from consumption terminal; With the earphone interface of audio conversion module 4 and consumption terminal, be connected respectively, for theaudio interface 5 of the communication that realizes card class read-write equipment and consumption terminal; The automatic identification module 6 of two standard audio interfaces be connected withaudio interface 5 with main control module 1;
Described card class module for reading and writing 2 is for reading the contactless IC card read/write unit of contactless ic card information.
Described main control module 1 is microprocessor.
Described consumption mobile terminal is mobile phone.
The audio interface 8 of the described card class of card class read-write equipment read-write equipment realizes and being connected that consumption is held by the earphone jack of consumption terminal; Because the difference of the two kind standards of audio interface is that audio input interface is different from the interface of the ground wire position, the present embodiment adopts two automatic identification modules 6 of standard audio interface, it utilizes the audio input interface voltage characteristic of the voltage of line interface above Ground, realize automatic identification function, and dock corresponding path, and then realize data interaction and operational applications function.
When consumption terminal need to send and swipe the card to described card class read-write equipment, key storage, during the steering order such as data encryption and authentication, the data that need to send receive byaudio interface 5 after at first by the audio coding decoding program coding in consumption terminal, being become sound signal, then the 4 pairs of sound signals of audio conversion module in described card class read-write equipment are carried out analog to digital conversion, described card class read-write equipment is controlled other parts according to the steering order content after conversion by the main control module 1 in described card class read-write equipment and is carried out this steering order, at card class module for reading and writing 2, safety chip 4, the keyboard of audio conversion module 6 and consumption terminal, after having coordinated this steering order, can output in consumption terminal by theaudio interface 5 in described card class read-write equipment.When described card class read-write equipment need to send data to consumption terminal, the data that send form sound signal after audio conversion module 4 is changed, and send to the earphone jack of the consumption terminal be connected with thisaudio interface 5 by theaudio interface 5 of described card class read-write equipment, after consumption terminal is received sound signal, can be undertaken by some modules of consumption terminal inside.
The present embodiment is realized compatible two audio interface standard of planting by the automatic identification module 6 of two standard audio interfaces; This card class read-write equipment can read contactless IC card, with consumption terminals such as mobile phone, panel computer, PC or PDA, is connected, and has realized that the consumer can realize the order of swiping the card and paying whenever and wherever possible, has improved the convenience of consumption and payment.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition, although used some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
