Connect the bluetooth module (earphone or data) of the described functional module of Data Control plate.
In the present embodiment, the earphone of described band Data Control plate can be divided into three kinds of mode of operations, traditional wire
Control pattern, data-transmission mode, mixed transmission modes, (but being not limited to these three pattern):
Starting the protocol conversion module of Data Control plate, described protocol conversion module sends corresponding control signal,
Disconnect the first switch, second switch and the 3rd switch, close the 4th switch, the 5th switch and the 6th switch,
Being closed at the 7th switch and open mike, now, described earphone is in tradition line traffic control pattern, ear now
Machine operates (with button) and uses with tradition line control earphone is just the same, custom convenient for users to use；
This is tradition line traffic control pattern.
Starting the protocol conversion module of Data Control plate, described protocol conversion module sends corresponding control signal,
Control the first switch, second switch and the 3rd switch, disconnect the 4th switch, the 5th switch and the 6th switch,
Simultaneously switching off the 7th and switch off mike, now, described earphone is in data-transmission mode, in this pattern
Under, all of information, such as actuation of keys information, the data message etc. that additional function modules produces, passes through
After protocol conversion module, produce and control the first switch, second switch and the control signal of the 3rd switch, by line
Control device drives MIC line to produce characteristic signal and be uploaded to main frame.Although the through swtich of button is disconnected, but
It is that traditional actuation of keys information such as Answer Key/volume increases key/subtract key or the combination of other any actuation of keys, still
After so can being connected to the data input of protocol conversion module, and these action messages are converted into second order data letter
Breath is uploaded after uploading or changing according to original single order data protocol.This is data-transmission mode.Due to wheat
Gram wind is disconnected, and this pattern is clear data pattern.
Starting the protocol conversion module of Data Control plate, described protocol conversion module sends corresponding control signal,
Control the first switch, second switch and the 3rd switch, close the 4th switch, the 5th switch and the 6th switch,
Being closed at the 7th switch and open mike, now, described earphone is in mixed transmission modes, in this pattern
Under, owing to the external through swtich of button closes, it is necessary to avoid transmission same of actuation of keys and second order data
Shi Jinhang.
But under clear data pattern, it is also possible to control to switch to another kind of mixed transmission modes, i.e. control Guan Bi
7th switch, opens mike.Now only access protocol conversion module due to button, with direct-passing mode is similar to
(during the i.e. the 4th the 5th the 6th switch Guan Bi), at this moment actuation of keys can specify that from protocol conversion module with soft
Property mode connects hero of biography machine through the first Switch Second Switch and the 3rd switch room.Same, these physics are pressed
Key action message, can also can upload with traditional line traffic control agreement with second order data agreement.Control mike

According to upload, upload despite the key features information produced with line control machine, the speed uploading data does not has
Limit, as long as corresponding audio frequency line control machine can produce the distinguishable key features information of the main frame on MIC line i.e.
Can.Such as can send the key features information realization transmission two that on MIC line, persistent period short interval time is short
Exponent number evidence, does not enumerates.Key features information certainly for different speed is transmitted, host side
Must have hardware or the software of the key features information on MIC line that receives.It is equipped with on main frame identifying traditional wire
The software and hardware (each producer may be different) of the key information (single order data) of control agreement, but for switch
Speed is accelerated, and characteristic information and interval all make software and hardware all None-identifieds of main frame cause reading number
According to time, main frame is it is necessary to have new software and hardware reads data.
The use of the band data pattern of earphone can be varied.User pass through operated key C, key+, key-, with
Singly-bound or many key combinations, notify described protocol conversion module the key features information with the agreement on MIC line
Combination notice main frame, it is achieved the pattern of earphone starts or switches or additional function controls.Traditional wire can be utilized
Unused or few key combination in the button of control, press the most for a long time key+or key-, carry out notification protocol
Modular converter starts data transmission, uploads main frame by MIC line simultaneously, main frame receive long key+or long key-
Or after button of other combination, the rear data receiver application program starting main frame.And when needing stopping data passing
Time defeated, key+or key-notify that two ends stop data pattern can being pressed the most for a long time, agreement maybe can be set and turn
Die change block recovers to original state state after being automatically stopped data transmission.After protocol conversion module starts, can perform pre-
If program such as judges that certain actuation of keys combines, control close/open mike or certain function of close/open
Module, or by the upper hero of biography after certain actuation of keys combined information output information fusion with certain functional module
Machine uses.
The interrupt signal that earphone is produced by threshold event is come, and notifies described protocol conversion module and with MIC line
On the key features information combination notice main frame of agreement, it is achieved the pattern of earphone start switching or terminate or
The process of data and exchange.Threshold value can be caused by functional module and produce, when functional module detects certain shape
Being signaled to the interrupting input of protocol conversion module during state, protocol conversion module starts and additional function mould
Block exchange data.Threshold value also can be caused by button and produce, i.e. after certain key combination is pressed, and described association
View modular converter identification also produces threshold value.Threshold value also can holding by the pre-set programs of the inside of protocol conversion module
Go and produce, such as clock etc..When threshold event occurs, can generation respective keys feature on line
Information notice host-initiated corresponding program.After data exchange, as operated further, respectively without preset
Module can be recovered automatically to original state state.The interrupt signal that threshold event produces also can be used to produce control data
Other module on plate and the control signal of switch, such as control the 7th switch of mike.

Additionally, Data Control plate can or another tradition line traffic control plate be connected in parallel on tone frequency channel wire, in conjunction with one
Rise and use.
The switch of described Data Control plate, what protocol conversion module, even line control machine function can be equivalent
Realize with other circuit or chip, such as MCU etc..It is not described further.
Exemplary operation state and program that data send earphone below carry out complete description, but are not limited to,
Refer to Fig. 3 and 4, it is the sequential of earphone using method of a kind of band Data Control plate of the embodiment of the present invention
Figure.
The power supply mode of earphone can be varied, such as battery, power supply etc. on line, does not goes one by one
Enumerate.Earphone power supply can manually opened or headset plug insert main frame after automatically turn on.
Before electric power starting, each signal is low level, and each switch is off.
When before described audio interface (wired mode=plug, wireless mode=bluetooth module) access host, respectively
Individual signal is low level, and each switch is off.Afterwards, main frame judges have earphone to access,
Starting tradition line traffic control driver, MIC line is driven and sets high level by the audio coding decoding chip of corresponding main frame,
The most if necessary, after the high level of MIC line is powered to the circuit realiration parasitism on Data Control plate,
MIC line is identified as high level, and audio frequency line control machine starts, and protocol conversion module startup simultaneously (can also be pre-
It is set to resting state), additional function modules can preset closedown or dormancy or unlatching as required.
Shown in part as corresponding in Fig. 3, now protocol conversion module puts control signal UP<5:3>is height, control
The corresponding switch of system Guan Bi makes three buttons directly and audio frequency line control machine is connected, control signal UP<6>simultaneously
For height, control Guan Bi the 7th switch (can also default conditions for disconnecting), mike be communicated to MIC line,
And control signal UP<2:0>sets low Automatic level control and disconnects corresponding switch.Now earphone is configured to traditional wire
Holding state under control pattern, the button operation holding of earphone is just the same with conventional earphone, such as single
Button C is music play/pause or answer/MUTE phone etc., and according to the electronic equipment of different brands
May arrange slightly different.
Now when there being phone to squeeze into, traditionally, push button C once, audio frequency line control machine is at MIC line
Upper generation key features information wire C signal, such as fork-shaped shade (the concrete MIC not shown here in Fig. 3
Waveform on line, because the possible hardware used of different brands and characteristic signal are all different), reach main frame electricity
Subset aft engine receives calls, and button C notification protocol modular converter is by UP<6 simultaneously>set high after open wheat
Gram wind (if in order to its default conditions of power saving are for disconnecting), MIC line starts to upload the sound of simulation
Signal two earplugs simultaneously accept the other side's sound that main frame transmits, it is achieved say two-way call.While call,
Can control by traditional single-button action regulation volume etc..Now earphone is in tradition line traffic control pattern.
In call, if needing to start second order data transmission mode, with the actuation of keys made an appointment, than
As pushed button for a long time+(or key-or the list of key C or any regulation or combination button action), if
UP<5:3>when being high level, audio frequency line control machine produces corresponding long line+signal (such as Fig. 3 on MIC line
In wide light dash area), main frame receives and after key range action, starts the second order data on main frame
Receive application program (such as corresponding APP).Simultaneously this push button for a long time+actuation of keys by association
After the INT+ of view modular converter inputs and is identified, start and wake up protocol conversion module entrance transmission mode up, this
Shi Ruguo control signal UP<5:3>is low level, i.e. disconnects respective switch, and any actuation of keys can only be passed through
Tri-data input port of INTc, INT+, INT-enter protocol conversion module, the most any button physically
Action and needed for other data of uploading can produce corresponding control according to new second order data coding protocol
Signal UP<2:0>, control input CALL, VOL+ and the VOL-of audio frequency line control machine, and changed by it
Key features information wire C on one-tenth MIC line, line+, line-be uploaded to main frame.Therefore protocol conversion module can
By pushing button for a long time+the action characteristic signal that is converted on identical or different MIC line upload, as
Shown in Fig. 3, now earphone is also when being in call and can upload data, and now earphone is in mixing and passes
Defeated pattern.
As shown in Figure 3, as the valid data of required transmission are 8 bit sequences 10000110, to this data set
If isolation, when noting control signal UP ＜ i ＞=1 of the switch of correspondence and continue certain time, then line traffic control
Device produces corresponding characteristic information on MIC line, according to second order number encoder agreement, control signal UP ＜ 2:0
＞ sequence is 100,010,001,001,001,001,010,010,001,100, if or only
Display control signal is the signal of 1, then be UP ＜ 2 ＞ UP<1>UP<0>UP<0>UP<0>
UP<0>UP<1>UP<1>UP<0>UP<2>, the key features information on MIC line such as figure in institute
Showing, the serial series of characteristic of correspondence signal is, line C line+line-line-line-line-line+line+line-line C.
Main frame notified startup second order data receives application program, receives and decode the data on the MIC line received,
Pass to other application of main frame.And the data transmission of next group can organize the end mark of data in the past for starting
Symbol continues transmission data.For the most brief data, can specify that and need not array isolation symbol line
C。
Now earphone is also in talking state, in order to increase earpiece volume, can configure Data Control plate and lead to
Know that main frame uses second order data interval to be more than the agreement of T0 less than T0, single order data, as it can be seen, permissible
Press key+, this information is distinguished as actuation of keys after receiving this information by INT+ by protocol conversion module,
According to the rules agreement produce on line key wire+.That is: this key features information wire+must be on line above
Start after the T0 time of any key features end of message, and do not permit in the T0 time after it terminates
Permitted to have key features information transmission on other line.Receive and be identified as key information by this protocol host, main
Machine i.e. increases left and right earplug volume.Now the transmission intercal of second order data is necessarily less than T0.In order to completely compatible
Single order data, can use the difference scheme of second order data coding protocol to transmit, so at transmission Arbitrary Difference
After data, volume is to maintain constant, and traditional volume increasing-and-decreasing key keeps constant.
It is also possible to press key C for notice Host Shutdown microphone data passage or in order to power saving is directly closed
The mike of earphone, by UP<6>set low.Or can be same with the permanent mute microphone (MIC) of certain key combination
Time protocol conversion module can be with up-delivering signal, one or many reminds main frame about the state of the closedown of mike.
Under mixed transmission modes or data-transmission mode, it is preferential that some actuation of keys information is transmitted on line
Level can specify that higher than transmission priority on the line of other second order data internal.I.e. press this button can suspend
Or block the transmission of any second order data, this key information of correspondence is preferentially upwards transmitted by regulation agreement.Such as Fig. 3
Shown in, during the transmission of second order data 10000110, as button need to be operated, such as press key C,
If reopening mike, protocol conversion module receives key C and presses, can send out isolation symbol after or
Do not send isolation symbol and stop second order data transmission at once, and by agreement, after being separated by certain time interval T 0 interval,
MIC line produces corresponding characteristic signal line C, and button on any line in the T0 time after forbidding
Open microphone data passage earphone simultaneously after characteristic information, host detection identification and open mike general
UP<6>set high.
Then, if necessary, protocol conversion module can transmit that complete group blocked above again
Second order data, or according to application scenarios needs, ignore truncated data above, direct sequential delivery next
Group data.
In Fig. 3, if required, can close data transmission but keep call, such as can long keying+,
After protocol conversion module receives, data transmission state, UP<5:3 can be stopped>setting high level, UP<2:0>
Keeping setting low level, earphone returns to be in tradition line traffic control pattern, corresponding long if desired for producing on MIC line
The characteristic signal line of degree+, main frame exits data receiver application program after receiving immediately.Earphone additional function mould
Block can be remained on or off as required.But call proceeds, until main frame turns off call.Now lead
Level on MIC line can actively (or be produced from HPL line or HPR line by machine so that regulation agreement is drop-down
Further feature signal reach protocol conversion module), protocol conversion module detect MIC line drop-down after, quilt
Knowing end of conversation, earphone is in the holding state of tradition line traffic control pattern.
Turn off call (being not drawn in figure) if desired for keeping data transmission, certain push-to can be pressed by regulation agreement
Know that main frame turns off call, or main frame actively turns off call.Now earphone is in data-transmission mode.
The source of the data that earphone is transmitted, can come from additional function modules, with I2C/SPI agreement and agreement
Modular converter exchange data, then protocol conversion module upload process cross or undressed from additional function
The initial data that module is read.Multiple additional function modules can be connected to protocol conversion module.On transmit
Data can be any length, the simplest for uploading single bit data, be such as certain when functional module
Plant sensor, if sensor itself or data processing module only need after processing the data of sensor
When passing two result datas, binary single-bit host-host protocol, three result data codings three can be used to enter
System, four results are encoded to the quaternary and upload such as, long line+, long line-, short-term+and short-term-, the most now
Main frame must shield the volume increase and decrease function of tradition line control push-button, otherwise can upload four knots by difference scheme
Really data, i.e. line+line+, line+line-, line-line+and line-line-.
If mike is opened for acquiescence, in order to provide more electric energy to data transmission and additional function modules,
Can data transmission and or additional function work time, mute microphone (MIC).
Described in superincumbent second order data coding protocol is coding based on key features information, two exponent numbers
Also include no matter key features information adjacent for any two on MIC line (is for two according to coding protocol
Exponent number according to or single order data) time interval encode, be called button space coding here.During button
Between finish time of previous key features information of being defined as on MIC line of interval and next key features information
Start time.Main frame can carry out timing to time interval, and specifies to decode according to our agreement.Ratio
Being logic 1 as interval is longer than Preset Time, being shorter than Preset Time is logical zero, forms binary coding, or
Main frame can distinguish thinner key press time interval, can carry out the coding of more multi-system.Because pressing in transmission
Key characteristic signal composition coding time, the time interval of two key features signals is necessary, therefore we
Can here except providing another kind of coding form, the most key is can sufficiently effective make use of by
Originally the interval time slatterned of key characteristic information coding, will further improve efficiency of transmission.Key features
Information coding and key press time space coding can be with individual transmission, it is possible to during mixed transport, and in mixed transport
Time, can be the individual transmission digital information representing two-way, it is also possible to brand-new mixed scale transmission numeral
Information.As a example by Fig. 4, shown between shielding wire C (the line C assumed and line+/ line-interval do not do between
Every coding) 15 hybrid codings are: long line-(long every) short-term+(long every) short-term-(long every) short-term-
(short every) short-term+(short every) long line+(long every) long line-(short every) short-term-, data sequence is equal to 2 (1)
1(1)0(1)0(0)1(0)3(1)2(0)0.Here 15 two or four mixing of single channel can be represented
The coded data of system: 211101001031200, or represent two-way absolute coding data: the quaternary
21001320 and binary one 110010.In fact between other any two key features information in figure time
Between be spaced all can be with encoding transmission information, such as during unique spacer coding, MIC line sends three continuously
And the interval of independent lines C (i.e. single order data) sends information, line C (short every) line C (long every) line C,
With line C (long every) line C (short every) line C, although being three the line C sent equally, but carry secretly more
Multi information, carries data 01 secretly for one, and another carries data 10 secretly, can also give in tradition line control earphone simultaneously
Three continuously and independent lines C (i.e. single order data) gives more meaning.Do not enumerate.Herein
Length every with short every simply relative to concept, as long as main frame can be differentiated.
When not using button space coding, mixed scale coding can also only with key features information no
With system composition mixed scale coding.
Device described in the present invention and module and function can realize can also realizing with software with hardware,
The most without restriction and enumerate.
The present invention utilizes the existing three key control functions of earphone, and (such as mobile phone is put down to vary without electronic equipment
Plate computer etc.) any hardware, and do not affect traditional earphone receiving talking function, only need to increase some
Switch and protocol conversion module, transmit data, convenient use with brand-new second order data coding protocol, become
This is cheap, considerably increases headset functionality and motility.
