Signal.
Step 502, one group of acoustic signals are converted into binary data；
, can be by multiple acoustic signals in this group after receiving device receives acoustic signals in the embodiment of the present invention
Binary data is converted to successively, wherein it is possible to restore 0,1 information, algorithmic formula such as formula by Goertzel algorithm
(2)：
S [n]=x [n]+2cos (w0) s [n-1]-s [n-2] (formula two)
Wherein, above-mentioned s [n] can represent the value of energy intensity；X [n] can represent the acoustic signals that microphone collects
Sequence；Cos (w0) can represent the frequency coefficient values that needs identify, the frequency coefficient values can pass through calculation formula：2*cos
(2*pi*freq/samplerate) is calculated；s[n-1],s[n-2]：It is a part for iteration, when n-1 and n-2 is less than 0
0 processing is done, example is as follows：S [0]=x [0]+2cos (w0) s [- 1]-s [- 2], s [1]=x [1]+2cos (w0) s [0]-s
[- 1], s [2]=x [2]+2cos (w0) s [1]-s [0].
In the embodiment of the present invention, an acoustic signals can be reduced to energy intensity value corresponding to one group, according to this group
Energy intensity value is that can determine that the binary number of the acoustic signals, such as：If the acoustic signals that one group of energy intensity is formed
In the presence of three crests, then it is assumed that the acoustic signals correspond to binary number " 1 ", if the acoustic signals that one group of energy intensity is formed
In the presence of two crests, then it is assumed that the acoustic signals correspond to binary number " 0 ".
It is appreciated that above three crest corresponds to binary number " 1 ", it is only this hair that two crests, which correspond to binary number " 0 ",
A kind of example of bright embodiment, in fact, the corresponding relation of above-mentioned acoustic signals and binary data can be by art technology
Personnel voluntarily determine as desired, such as：Five crests correspond to binary number " 1 ", and six crests correspond to binary number " 0 " etc.
Deng the embodiment of the present invention is not specifically limited to this.
Step 503, the binary data is converted into corresponding data message.
In the embodiment of the present invention, the binary data that above-mentioned acoustic signals are changed is converted into corresponding data message.

Step C3, identified data block number phase is identified in the binary data blocks number and the data block total number
Meanwhile the index mark carried according to the binary data is ranked up to the binary data group.
In the embodiment of the present invention, above-mentioned lead code and rear leading code are specific binary data sequence, as shown in Figure 4：
Lead code is 20bit binary number " 1 ", and rear leading code is 10bit binary number " 0 ".The embodiment of the present invention can pass through number
Data block number is determined according to block sum mark.
Data block can be determined by the lead code and rear leading code of identification, and then the number of data block can be determined, in number
According to data block number corresponding to number and the data block total number mark of block it is identical when, the data that illustrate to receive be it is complete, now
Can according to carried in binary data index mark binary data is resequenced, with ensure data message according to
Correct order is shown, and then ensures the accuracy of data message, and the prompt tone that played data is properly received simultaneously, to send out
After sending equipment to receive prompt tone, stop the transmission of acoustic signals；It is corresponding with data block total number mark in the number of data block
When data block number differs, illustrate that data message there are lost part data in transmitting procedure, therefore the data message received is not
Accurately, the binary data is abandoned, continues to acoustic signals.
The embodiment of the present invention can verify after acoustic signals are converted into binary data to binary data,
If data have no problem by verification, binary data is reduced to corresponding data message, if data are not over school
Test, abandon the data, ensure the accuracy of data with this.
To make those skilled in the art be better understood from the embodiment of the present invention, sound is based on below by way of one kind shown in Fig. 6
The example of the data transmission method of ripple is illustrated to the embodiment of the present invention：
Step 601, receiving device microphone listen to send equipment have acoustic signals send (such as：Receive hair
The transmission prompt tone of sending end) when, gather acoustic signals；
Step 602, according to Fast Fourier Transform (FFT) and Goertzel algorithm, analyze frequency corresponding to acoustic signals, also
Original goes out original binary data；
Step 603, judge whether the lead code of data signal is consistent with value with our quantity predetermined in advance, if differ
Cause, directly abandon, if unanimously, data are constantly received, until encountering rear leading code；
Step 604, start the data signal that verification recovers, if data signal has no problem by verification, continue executing with
Step 605, otherwise abandon.
Step 605, start to the data in data signal according to index order, while confirm block number, until data connect
Harvest complete.
In the embodiment of the present invention, after acoustic signals are converted into binary data, remove lead code and this portion of rear leading code
After dividing voice protocol information, confirm whether data are correct, if correct, data block is ranked up according to index.When incoming number
After all correct, system reducing goes out original data message, such as："hello,world！".
