The scope of bright embodiment includes the gamut of claims, and all obtainable of claims is equal to
Thing.Herein, these embodiments of the present invention can be represented individually or generally with term " invention ", and this is only
For convenience, and if in fact disclose invention more than one, be not meant to automatically to limit this application in the range of appointing
What single invention or inventive concept.
As it is shown in figure 1, the invention provides a kind of self adaptation sound wave wireless network configuration method.The microphone of different model
Having different frequency responses, the present invention obtains, by using scanning Quick Response Code, the microphone model that receiving terminal uses, by right
The microphone of different model selects suitable frequency of sound wave scope, and transmitting terminal uses the sound wave of different frequency to encode waiting for transmission
Network configuration information, receiving terminal gathers sound wave by microphone, does frequency analysis, error detection, and finally decoding synthesizes original net
Network configuration information.Idiographic flow is as follows:
1st, transmitting terminal scanning receiving terminal Quick Response Code, obtains the microphone type information of receiving terminal, selects corresponding frequency word
Section.Wherein, the microphone of different model has different frequency of sound wave responses.
2nd, transmitting terminal is according to the sample frequency of the receiving terminal microphone of different model, by scanning the frequency response of microphone
Curve, selects the region that gain is bigger as frequency of sound wave scope to be encoded, because sound wave available frequency range is limited, selects
17 frequencies, wherein 16 are used for doing code character, and other 1 frequency is used for doing synchronous code.Wherein, transmitting terminal (such as mobile phone) produces
The equal amplitude sine wave signal of raw upwards increasing frequency (being incremented by 200Hz every time), each frequency persistently about 80ms；
Wherein, do UTF-8 conversion to network configuration information to be encoded, then each character is split into 2 independent
Half character (4bit), encodes data to be sent by 16 frequencies.Transmitting terminal first sends a synchronous code frequency, retransmits one
Individual fixed character 0, then sends fixing length coding, then sends the frequency corresponding to data after coding, finally send
All data corresponding CRC check code.
3rd, transmitting terminal allows receiving terminal enter network configuration pattern while sending information, and is constantly gathered volume by microphone
The corresponding frequency of sound wave of network configuration information of code.Wherein, receiving terminal is provided with switch, is manually operable entrance network configuration mould
Formula and standby both of which.
4th, the frequency of sound wave information gathering is done real-time frequency analysis by receiving terminal, after listening to the frequency of synchronization code word,
Enter decoding schema, next receive character late, if the character receiving is the corresponding frequency of character 0, then enter
Regular length decoded state, finally receives the data of regular length.
5th, doing nibble splicing to the data of decoding, finally carrying out CRC check, if verifying successfully, then data transfer
Finish, otherwise abandon, reenter synchronous code listening state.
6th, it by receiving the network configuration information of coding, is partitioned into SSID and the password being connected to wireless network, then
Access network is gone to connect.
Wherein, in the present embodiment step (2), it is possible to take the network configuration information figure to be encoded that will gather on PC
Shape TO analyzes (such as Adobe audition software), can check out that the corresponding amplitude of different frequency is different, therefrom
The frequency range selecting one section of continuous print amplitude bigger sends to receiving terminal after carrying out UTF-8 conversion as frequency of sound wave scope.
The particular order of the step during disclosed in should be understood that or level are the examples of illustrative methods.Based on setting
Meter preference, it should be appreciated that during the particular order of step or level can be in the feelings of the protection domain without departing from the disclosure
Rearranged under condition.Appended claim to a method gives the key element of various step with exemplary order, and not
It is intended to be limited to described particular order or level.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit, to the greatest extent
The present invention has been described in detail by pipe with reference to above-described embodiment, and those of ordinary skill in the field still can be to this
Bright detailed description of the invention is modified or equivalent, these without departing from spirit and scope of the invention any modification or
Equivalent, all within the claims of the present invention that application is awaited the reply.
