Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
Embodiment 1
The present embodiment provides a kind of transmission method of audio signal, is applied to the audio signal transmission between intelligent cipher key equipment and mobile terminal.Intelligent cipher key equipment can be the key that ensures information security for signing, have the E-token dynamic password card that generates dynamic password function according to challenge code, and mobile terminal can be the equipment with audio interface such as notebook computer, panel computer, mobile phone, intelligent watch, intelligent glasses.Intelligent cipher key equipment can be connected by audio interface with mobile terminal, the audio interface of intelligent cipher key equipment and the audio interface of terminal match, intelligent cipher key equipment is connected and carries out the transmission of audio signal with terminal by its audio interface, wherein intelligent cipher key equipment can possess audio interface, can be also audio interface by its USB interface switching; Intelligent cipher key equipment and mobile terminal can also be by loud speaker and microphone transmission of audio signals.
The flow chart of the transmission method of the audio signal that Fig. 1 provides for the embodiment of the present invention 1, as shown in Figure 1, the method comprises the following steps:
Step 101, mobile terminal is encoded to the format information of waveform corresponding to audio signal according to the first coded system, obtains coded data, wherein, the first coded system is that mobile terminal sends the coded system that waveform corresponding to audio signal uses, and above-mentioned format information comprises: valid data; Be positioned at the length of the front protected field of valid data frame before; Be positioned at the length of valid data postamble protected field afterwards; And, be positioned at before frame after protected field and be positioned at before valid data for determining the length of the domain field that valid data start.
The first coded system can be one or more coded systems that mobile terminal is supported, be that mobile terminal is can use one or more coded systems to send format information time, and intelligent cipher key equipment can be correctly decoded the waveform that uses this first coded system to send, and obtains valid data.It should be noted that, at mobile terminal, in the time using multiple coded system, intelligent cipher key equipment can identify the coded system that certain section of waveform uses.
Above-mentioned format information being fade-in during for mobile terminal transmitted waveform gradually goes out property settings, when causing mobile terminal transmitted waveform, the characteristic of mobile terminal self there is the problem gradually going out that is fade-in, be fade-in while gradually going out to refer to the waveform that mobile terminal sends or received audio signal is corresponding, the start-up portion of waveform is by zero amplitude that rises to gradually valid data in waveform, and the latter end of waveform is reduced to zero gradually by the amplitude of valid data.The above-mentioned characteristic of mobile terminal can cause the waveform of the part valid data of transmission to do well in being fade-in gradually, and the waveforms amplitude that this part valid data is corresponding reduces, and is even zero, and the waveform of transmission is imperfect, loses important data.
Utilize the front protected field of frame and postamble protected field can offset being fade-in of mobile terminal and gradually go out characteristic, thereby guarantee the integrality of waveform transmission between intelligent cipher key equipment and mobile terminal; And utilize domain field to determine the beginning of valid data, make mobile terminal and/or intelligent cipher key equipment can accurately obtain valid data.
For example, before frame, protected field length is 1000 bits, when mobile terminal receives waveform, under the impact being fade-in at waveform, before frame, front 900 waveforms amplitude corresponding to bit of protected field are zero, and rear 100 bits rise to waveforms amplitude corresponding to domain field gradually by zero; Postamble protected field length is 1000 bits; when mobile terminal receives waveform; under the impact gradually going out at waveform, the waveform that front 100 bits of postamble protected field are corresponding is reduced to zero gradually by waveforms amplitude corresponding to valid data, and rear 900 waveforms amplitude corresponding to bit are zero.Therefore, use the front protected field of frame to offset the impact that waveform is fade-in, use postamble protected field to offset the impact that waveform gradually goes out, thereby guarantee that the waveform of valid data is complete.The situation that mobile terminal sends waveform is similar with the situation that receives waveform, repeats no more herein.Certainly, before frame, protected field can be also different from the length of postamble protected field, and this is to be determined by the self-characteristic of mobile terminal.

Above-mentioned format information can also comprise: is positioned at before frame after protected field and is positioned at the length of the data head before valid data, and after being positioned at valid data and be positioned at the length of the data tail before postamble protected field.Data head is used for making audio stream output amplitude stable, informs that the receiving terminal of data enters synchronous regime, and data tail is for informing that the receiving terminal of data finishes phonetic incepting.The bit of protected field and the bit of data head can identical (for example, being bit 1) before frame, also can be different (for example, before frame, protected field is n 1, and data head is m individual 0); In like manner, the bit of postamble protected field can be identical with the bit of data tail, also can be different.
In addition,, before mobile terminal is encoded according to the format information of the first coded system corresponding waveform to audio signal, said method also comprises: mobile terminal and intelligent cipher key equipment all obtain the first coded system and the second coded system.Mobile terminal and intelligent cipher key equipment all get the coded system that self and the other side support, and can be correctly decoded the waveform that the other side utilizes coded system that the other side supports to send, thereby guarantee being correctly decoded of data.Mobile terminal and intelligent cipher key equipment can mode through consultation obtain the first coded system and the second coded system.
In the present embodiment, the format information of waveform corresponding its transmission of audio signal is sent to intelligent cipher key equipment by mobile terminal, make intelligent cipher key equipment to send waveform to mobile terminal according to this format information, avoid mobile terminal to be fade-in the impact that gradually goes out characteristic, guarantee that mobile terminal receives the waveform of complete valid data, and then obtain complete valid data.Utilize the front protected field of frame and postamble protected field to offset being fade-in of mobile terminal and gradually go out characteristic, thereby guarantee the integrality of the waveform transmission of valid data between intelligent cipher key equipment and mobile terminal; And utilize domain field to determine the beginning of valid data, make mobile terminal and/or intelligent cipher key equipment can accurately obtain valid data.
