Description
Technical field
The present invention relates to a kind of payment system of traffic system, relate in particular to a kind of traffic system audio data transmission near field payment system that sound is signal transmission medium of take.
Background technology
Along with going deep into of E-business applications, particularly at O2O(Online To Offline) under pattern promotes, market needs to meet by mobile terminals such as mobile phones more carries out the application power that (as the E-Payment in 1 meter) accepted near field transaction.At present, industry is placed on principal focal point in the application based on SWP technical manual, and to realize NFC ability, its main implementation has two kinds: (1) is based on NFC-SIM card; (2) based on NFC-SD card.No matter be to adopt SWP or adopt RFID technology, they all exist necessary hardware foundation to support, such as: plug-in rfid card sheet, transformation of the way mobile phone etc., this is unfavorable for the requirement of universality, convenience and the security of business application, therefore everybody is actively finding new technology or application scheme.There is abroad the application based on electric signal transmission based on mobile phone 3.5mm earphone interface.The shortcoming of this scheme is: the wireless transmission that cannot realize data.NaRaTTe company releases the mobile phone application based on Zoosh technology in June, 2011, and it is realized based on converting the electrical signal to hyperacoustic data transmission scheme by the microphone on mobile phone and loudspeaker.The shortcoming of this scheme is: it is based on hyperacoustic, need to transform mobile phone, does not possess in practical universality.
Mobile phone two-dimension code is the application of planar bar code technology on mobile phone.Quick Response Code is the barcode technology of new generation of the chequered with black and white rectangle square formation record data symbolic information that distributes in plane (on two-dimensional directional) according to certain rules with specific geometric figure, by a Quick Response Code Matrix Pattern and a Quick Response Code number, and the comment of below forms, have and contain much information, error correcting capability is strong, recognition speed is fast, the features such as comprehensive recognition.But its defect is to utilize the camera recognition of mobile phone, so require mobile phone to have high-precision camera function, does not have equally universality; Even if there is high-precision camera function, due to shooting, be subject to the impact of the external environments such as light larger, so still there is the problem of signal transmission precision deficiency, its error is larger.
In traffic system, the existing modes of payments is except traditional money transaction, money transfer transactions mode, also useful mobile phone two-dimension code technology is concluded the business, but all there is above-mentioned defect in above-mentioned these modes of doing business, in use, there is very large transaction drawback, cannot adapt to high-level efficiency and the universality requirement of modern society.
Summary of the invention
Object of the present invention is just to provide in order to address the above problem a kind of traffic system audio data transmission near field payment system that sound is signal transmission medium of take.
In order to achieve the above object, the present invention has adopted following technical scheme:
The present invention includes traffic system audio frequency transmitting-receiving payment device and audio frequency transceiver terminal, described traffic system audio frequency transmitting-receiving payment device and described audio frequency transceiver terminal are all built-in with voice frequency sender and audio receiver.
In application, the user of audio frequency transceiver terminal can Direct Recognition by the voice frequency sender in the mobile terminals such as mobile phone Applied Digital data-signal according to certain transformation rule, be converted into common acoustic signal, with the loudspeaker of common mobile terminal, can send this signal; At traffic system audio frequency transmitting-receiving payment device, after receiving common voice signal, audio receiver is converted into according to corresponding transformation rule the Applied Digital data-signal that user can Direct Recognition, and complete communication, thereby realized in-plant electronic transaction.A corresponding software is installed on common mobile terminal and can be realized above-mentioned functions, so there is universality, can apply.Above-mentioned audio frequency transceiver terminal can be realized two-way communication, has been convenient to comparatively complicated electronic transaction; The quantity of above-mentioned audio frequency transceiver terminal can, for above any number of of 2 or 2, be decided according to the actual requirements.
Particularly, described voice frequency sender comprises scrambler, modulator, wave filter, D/A change-over circuit, amplifirer and loudspeaker, the output terminal of described scrambler is connected with the input end of described modulator, the output terminal of described modulator is connected with the input end of described wave filter, the output terminal of described wave filter is connected with the input end of described D/A change-over circuit, the output terminal of described D/A change-over circuit is connected with the input end of described amplifirer, and the output terminal of described amplifirer is connected with the input end of described loudspeaker; Described audio receiver comprises microphone, A/D change-over circuit, bandpass filter, detuner, low-pass filter and demoder, the output terminal of described microphone is connected with the input end of described A/D change-over circuit, the output terminal of described A/D change-over circuit is connected with the input end of described bandpass filter, the output terminal of described bandpass filter is connected with the input end of described detuner, the output terminal of described detuner is connected with the input end of described low-pass filter, and the output terminal of described low-pass filter is connected with the input end of described demoder.Said system can be selected the minimum integrated circuit of volume in actual applications, as the traffic system audio frequency transmitting-receiving payment device as administrative center; Also can select to realize the software of corresponding function, the audio frequency transceiver terminal as the means of payment, is decided according to the actual requirements.
Particularly, described audio frequency transceiver terminal is mobile phone or panel computer, as long as have corresponding voice frequency sender, audio receiver and running software ability.
Beneficial effect of the present invention is:
By the present invention, can utilize the conventional func unit of the mobile terminals such as mobile phone, without mobile terminal is carried out to special hardware transformation, only need process means by simple technique, can realize mobile terminal and be the audio frequency transceiver terminal of user side and the ticket between traffic system audio frequency transmitting-receiving payment device, air ticket, steamer ticket etc. and closely (conventionally be controlled in 1 ~ 3cm) electronic transaction, make the closely electronic transaction of traffic system become safe, convenient, and can spread.
