In the present embodiment, the audio jack of infrared launcher at least comprises power lead and signal wire.Wherein, this power lead is electrically connected with the power end of controller and the power end of infrared transtation mission circuit respectively; As a kind of be the power supply mode of infrared launcher, mobile terminal by its audio sockets microphone leads, power (comprise and powering to controller and infrared transtation mission circuit) to infrared launcher through this power lead.As a kind of be the power supply mode of infrared launcher, power supply can be added (as battery core in infrared launcher, for another example chargeable battery core), powered (comprise and powering to controller and infrared transtation mission circuit) to infrared launcher by this power supply.After infrared launcher works on power, can under the state of the audio sockets grafting of the audio jack of this infrared launcher and mobile terminal, from the voice data (comprising carrier data and information data) that described audio jack mobile terminal receive exports.
Simultaneously, signal wire in the audio jack of infrared launcher goes between with the receiver in the audio sockets of mobile terminal and is connected, the voice data (this voice data at least comprises carrier data and information data) that infrared launcher is exported from this receiver lead-in wire by this signal wire mobile terminal receive.
As an embodiment, the audio jack of infrared launcher adopts headset plug to realize, and accordingly, the audio sockets of mobile terminal adopts receiver J-Horner to realize.
Step S1, the carrier data exported from described audio jack mobile terminal receive and information data.
In embodiments of the present invention, due to distinct electronic apparatuses, the carrier frequency of its compatibility is different, and namely its carrier frequency that can detect is different, the carrier frequency therefore needing mobile terminal to obtain electronic equipment in advance to identify; The mode obtained at least comprises: 1, when learning the unit type of electronic equipment, from the server of internet or mobile radio communication, directly obtains the carrier frequency that this electronic equipment is supported; 2, set up the communication connection between electronic equipment and mobile terminal, and then the carrier frequency that mobile terminal can directly ask electronic equipment to be supported to obtain this electronic equipment.
And then, in order to use this carrier frequency to generate infrared code, mobile terminal to while infrared launcher output information data, also to infrared launcher outgoing carrier data; Preferably, mobile terminal is successively to infrared launcher outgoing carrier data and information data, wherein, carrier data and information data are from original infrared code and have carrier wave duration and carrierfree duration the voice data extracting and be encoded into the transmission of applicable audio port, thus, infrared launcher first can parse carrier frequency from carrier data, and then identifies information data, to modulate and generate infrared code with the carrier frequency first identified to this information data.
Thus, the carrier data that infrared launcher is exported by audio jack mobile terminal receive and information data; As an embodiment, infrared launcher is by the signal wire in this audio jack, and mobile terminal receive to go between the carrier data and information data that export successively from this receiver.

As a kind of modulation system, controller is reception carrier data and information data successively, after device to be controlled completes the reception to carrier data, carrier frequency is parsed from described carrier data, then in the process receiving information data, synchronously the information data received modulated and generate infrared code, making infrared transtation mission circuit launch described infrared code to electronic equipment in time, effectively improve the ageing and real-time using mobile terminal to control electronic equipment, have more hommization.
As another modulation system, controller is reception carrier data and information data successively, after device to be controlled completes the reception to carrier data, carrier frequency is parsed from described carrier data, then, after device to be controlled completes the reception to information data, whole information data is modulated and generates infrared code.And then, launch described infrared code by infrared transtation mission circuit to electronic equipment.Owing to being modulate whole information data, can compression algorithm be used before modulation further to carry out data compression to information data, improve the data transmission efficiency of information data, save transmission bandwidth, reduce the transmission time of the infrared code of transmission; Accordingly, electronic equipment needs to use corresponding decompression algorithm to carry out decompress(ion) to the infrared code received, and restores whole information data.
Fig. 3 shows the another optimized work flow of the infrared remote control method that the embodiment of the present invention provides, and for convenience of description, illustrate only the part relevant to the embodiment of the present invention.
In an embodiment of the present invention, as shown in Figure 3, the described carrier data from described audio jack mobile terminal receive output and this step of information data, be specially:
Step S11, receives lead code that described mobile terminal exports, carrier data and information data successively from described audio jack.
In the present embodiment, lead code, carrier data and the information data packing framing that mobile terminal will be arranged in order, exports to infrared launcher in the mode of frame.Preferably, under normal circumstances, the code word that lead code is used and carrier data code word used are all fixing, therefore the data volume size of the information data that this frame can comprise can be determined according to the byte length of frame, and then determine instruction to be packaged into a frame or multiframe, or determine to pack the data to a frame or multiframe.
In the present embodiment, for the controller of infrared launcher can recognize frame, for consisting of of every frame: foremost is lead code, being then carrier data, is finally information data.Like this, the controller of infrared launcher is after this lead code being detected, and learning next can reception carrier data and information data successively; And then after the reception having recognized this lead code, reception carrier data and information data successively.
Correspondingly, described from described carrier data, parse this step of carrier frequency by described controller before, described infrared remote control method also comprises step S6 and step S7.
Step S6, the lead code exported by audio jack described in described controller identification.
Step S7, after described controller identifies described lead code, receives the described carrier data of described audio jack output and described information data successively by described controller.
As the embodiment performing step S6 and step S7 successively, the controller of infrared launcher completes the reception of this lead code, after identifying this lead code, and reception carrier data and information data successively immediately.
As the embodiment performing step S6 and step S7 successively, because lead code is fixing, so the time sent needed for this lead code is fixing, using the time needed for this lead code of transmission as the very first time; In like manner the code word of described carrier data is also fixing, and the time sent needed for this carrier data is also fixing, using the time needed for this carrier data of transmission as the second time; And then, the data volume (code word) contained due to every frame is also fixing, therefore the data volume of information data that a frame can carry also is fixing, so the time of this information data of continuous reception is also fixing, using time of sending needed for this information data as the 3rd time.
And then in the present embodiment, described this step of lead code exported by audio jack described in described controller identification, is specially:
Continue the very first time when described controller starts described lead code to be detected by described controller and receive described lead code.
In the present embodiment, the controller of infrared launcher is when this lead code being detected at the beginning, the lasting very first time receives described lead code, during this very first time lasting receives lead code, once not recognize lead code, abandon the reception to this frame, if continue the very first time to recognize this lead code, after this very first time, reception carrier data and information data successively immediately.As a preferred embodiment, lead code is " 1 " signal of the lasting very first time, should high level be adopted to represent by " 1 " signal, and then, controller when receiving a frame, when just having started high level to be detected, represent and lead code detected, and then whether lasting very first time detection is high level, if this high level continue for the very first time, then starts the reception to described carrier data and described information data immediately.
Accordingly, described described carrier data and this step of described information data being received the output of described audio jack by described controller successively, is specially:
Described controller complete the lasting described very first time receive described lead code time, by described controller continue the second time carry out level detection and detect export described carrier data;
When described controller completes the level detection of lasting described second time, carried out level detection and detect exporting described information data by described controller lasting 3rd time.
In the present embodiment, controller has input pin, and this input pin is electrically connected with the signal wire in audio jack.And then the mode of controller reception carrier data is: within the second time of every frame continue level on the signal wire in audio jack is detected, according to detect in the second time, change level determine described carrier data.For this carrier data, this carrier data obtains after being through mobile terminal employing assignment algorithm coding; And then controller need adopt this assignment algorithm or the decoding algorithm corresponding with this assignment algorithm to decode to this carrier data, decodes carrier frequency.As an embodiment, mobile terminal adopts binary representation carrier frequency, take carrier frequency as 36KHZ be example, the corresponding carrier data obtained of encoding is " 00110110 " signal, mobile terminal exports " 00110110 " signal by headphone line, particularly, is divided into 8 sub-time intervals the second time, if " 1 " signal in " 00110110 " signal need be exported by headphone line, then export high level at the sub-time interval corresponding with this " 1 " signal, if " 0 " signal in " 00110110 " signal need be exported by headphone line, then in the sub-time interval output low level corresponding with this " 0 " signal, and then, controller continues according to time sequencing to detect the level on the signal wire in audio jack within the second time of every frame, high level is detected at certain sub-time interval, then generate " 1 " signal, ground level detected at certain sub-time interval, then generate " 0 " signal, by that analogy, after the second time, controller completes the reception to " 00110110 " signal, demodulates carrier frequency: 36KHZ from " 00110110 " signal.It should be noted that, above-mentioned is only the example explanation that 36KHZ carries out following content for example with carrier frequency, as long as the mode that the principle had based on this example and spirit select other assignment algorithm to complete the Code And Decode of carrier frequency all can be used for the present embodiment, do not limit at this, the content that above-mentioned example illustrates comprises: how mobile terminal adopts assignment algorithm to encode to carrier frequency, by headphone line to infrared launcher send coding generate carrier data after, how infrared launcher correctly detects this carrier data, how to decode carrier frequency from this carrier data.
In the present embodiment, when described controller completes the level detection of lasting described second time, the reception of information data can be carried out immediately, controller receives the mode of information data: continue to detect level on the signal wire in audio jack within the 3rd time of every frame, according to detect in the 3rd time, the level of change determines described information data.
In the present invention one preferred implementation, described controller is when the level detection of described second time and all adopt the timing of Microsecond grade when the level detection of described 3rd time, carries out timing to the duration of the level detecting constant (high level or low level).
Accordingly, describedly continued for the 3rd time by described controller and carry out level detection and detect exporting described information data this step and being specially;

As another concrete mode, if the duration that the high level detected remains unchanged reaches the very first time, be then defined as receiving " 1 " signal; If the duration that the low level detected remains unchanged reached for the second time, be then defined as receiving " 0 " signal.By that analogy, if the high level detected continue for this very first time multiple, be then defined as receiving multiple " 1 " signal; If the low level detected continue for this second time multiple, be then defined as receiving multiple " 0 " signal.Therefore, the duration that can remain unchanged according to time sequencing and according to the level detected, the information data be made up of " 0 " signal and/or " 1 " is determined successively.
In the present invention one preferred implementation, described described information data to be modulated in described carrier frequency and to generate this step of infrared code be specially; Carry out in the process of level detection within described 3rd time, generate infrared code according to the level modulation detected successively according to time sequencing.
