Description
Technical field
The utility model relates to technical field of data transmission, relates in particular to a kind ofly to realize that by sound the system of transfer of data and data send, receiving terminal.
Background technology
Carry out transfer of data by sound, the process that not only realizes is simple, and the cost of realizing is also cheaper.We can retrieve many patent documentations that carry out transfer of data by sound, for example, Chinese patent application numbers 201110349377.4, the utility model name is called: a kind of method of carrying out the mobile phone on-site payment by audio signal, a kind of exactly application that realizes data transmission method by sound.
In the disclosed technology contents of this patent, it by the method that sound carries out transfer of data is: as shown in Figure 1, the gathering client is calculated the check value of the transmission of data, giving needs the transmission of data to add verification beginning flag and check value, form partial data, each numerical value of described partial data is transformed on corresponding dual-tone multifrequency superposed signal more afterwards, forms continuous multitone multifrequency superposed signal information according to sending duration, realized the corresponding conversion of data and multitone multifrequency acoustic signals.At last, the gathering client is crossed the dual-tone multifrequency superposed signal information exchange that is converted to and is sent continuously the acoustic signals mode and send, after the acoustic signals that the payment client sends to the client of collecting money, preserve, then the acoustic signals of this preservation calculated, decodes, then the data of decoding are carried out verification.So far, completed the process of passing through the transfer voice data.

Embodiment
Below, by reference to the accompanying drawings the utility model is described in detail.
As shown in Figure 2, the present embodiment provides a kind of method that realizes transfer of data by sound, and the method comprises:
Above-mentioned data transmission method, make the data that to transmit between data sending terminal and data receiver than large information capacity, voice data for example, view data and large file data etc., effectively improved the efficient of transmission, overcome between the data sending terminal described in background technology and data receiver and can not realize by sound the drawback of large information capacity transfer of data.Simultaneously, above-mentioned data transmission method has adopted the implementation of dynamic coding, that is: by generate on transfer server with the dynamic coding table of out-of-service time to carrying out Code And Decode by the key of transfer voice, even if making key is recorded in transmitting procedure, also can't be cracked within the effective time of dynamic coding table and imitate, improve reliability and the confidentiality of transfer of data.
Wherein, described generation comprises with the dynamic coding table of out-of-service time: according to current time and the content that will transmit, and the random coding schedule that comprises sound frequency and sound waveform that generates, this coding schedule ceases to be in force automatically in preset time.Here, described sound waveform comprises: sine wave, square wave and impulse wave.Described sound frequency comprises: the sound that the audio frequency that people's ear can be heard and people's ear can not be heard.Described audio frequency comprises: single-tone audio frequency, double-tone audio frequency and multitone audio frequency.
During audio transmission, there are two core index can affect the content of transmission: sound frequency and sound waveform.Audio frequency in the sound is as example, due to the audio coding table in the stochastic and dynamic of transfer server generates, according to the difference of time, transferring content, transfer server can generate dynamic coding table, transmission frequency and transmitted waveform at random, so the key of audio frequency and transmission is without fixed correspondence.For example, " 0 " in dynamic coding representative this moment represents that audio frequency is 1760Hz, uses sine wave transmissions; But " 0 " in the dynamic coding table that dynamically generated afterwards in 1 second just represents that audio frequency is 19200Hz, uses the square wave transmission, perhaps other frequency and other waveform.
Described generation is with the dynamic coding table of out-of-service time, and for example, data sending terminal 10 time that data receiver 20 receives sound that plays sound is 5-10 second, so be 10 seconds the effective time that we can arrange the dynamic coding table.After completing transmission, perhaps the transmission time surpasses 10 seconds, and the dynamic coding table ceases to be in force automatically, to guarantee that transferring content can not be ravesdropping and forge.

Start bit [QS] is set to length and is the high frequency audio of 2, represents that this is the initial of a section audio.
Bits of coded [CODE] is set to length and is the data of 10, and these data represent normal the transmission of data, i.e. our described unique key.One in corresponding " 0-9 "+" a-v " 32 bit data of each data transmits.The different audio frequency of each corresponding 20Hz – 20000Hz.In view of the hardware index of transceiver, transition interval is 100Hz.Example: 1760Hz represents " 0 ", and 1860Hz represents " 1 ", and 1960Hz represents " 2 ".
Check digit [Correction], the coding that adopts Reed-Solomon Reed Solomon code coded system to carry out arranges length and is the data of 8, can carry out verification and error correction to the data in bits of coded.For example, in data transmission procedure, occur multidigit disappearance or mistake in the coding of 10, can directly revise by check digit, when guaranteeing to greatest extent accuracy, can reduce the number of times of repeat playing.
In the situation that 8 check digit are arranged, can provide to 10 bit data in bits of coded the error correction of 4.Serious forgiveness is enough to resist the interference of noisy environment and other sound wave up to 40%, only needs single transmission simultaneously, improves stability.
Described tape verifying error correction coded system comprises: Reed-Solomon coding, BCH code, turbine code, low density parity check code and convolution code.
In above-mentioned data transmission method, its core is to use dynamic coding schedule that the uniquely identified key is encoded, namely so-called encryption.Therefore, encryption system commonly used all is applicable to this encryption purpose.Common encryption system has public, private key encryption system and symmetric cryptography system, is not technological improvement point of the present utility model place owing to how to encrypt, so be not described in detail at this.
Due in the dynamic coding process, what be provided with tape verifying error correction coded system can carry out to described coding the check digit of check sum error correction, therefore make the interference that to resist noisy environment He other sound wave by the data of transfer voice, improved the stability of transfer of data.
