Embodiment
Fig. 1 is system schematic of the present invention.
Wherein 101 is the first equipment, can but be not limited to mobile phone; Wherein 103 is the loudspeaker unit of the first equipment, for MAC Address being sent by sound; 105 is the radio hardware module of the first equipment; 107 is the connection management module of the first equipment, and connection management module can be a software with interface, can read this equipment wireless MAC address when its startup optimization by system interface; 107 connection management modules, imposing a condition under triggering, begin through 103 horn module and sound, superposed wireless MAC address date in voice signal.102 is the second equipment, and 104 is the microphone unit of the second equipment, and 102 equipment obtain voice datas by 104; 106 is the radio hardware module of the second equipment; 108 is the connection management module of the second equipment, the speech data that 108 module monitors microphone 104 unit receive, and when being resolved to effective Mac address, then initiates connection requests by 106 modules.
Fig. 2 is of the present invention for bluetooth First Contact Connections process chart.
Wherein the first equipment 201 reads local Bluetooth MAC address, and sounds 205 by loudspeaker unit 202, and wherein MAC Address is modulated is loaded in voice.Second equipment 204 picks up sound by its microphone unit 203, and monitor sound always, when sound signal intensity is greater than certain threshold value, then start to carry out demodulation to voice signal, when its unsuccessful demodulation in sound goes out the Bluetooth MAC address of the first equipment, then start to initiate Bluetooth pairing request 206, first equipment end reply confirmation and accept pairing request 207, the success of bluetooth connection establishment.Further, two-way can foundation applies connection 208.
Fig. 3 of the present inventionly has the 3rd equipment to carry out the process chart connected.
First first wireless device 301 and the second wireless device 302 set up wireless connections.At this moment the 3rd wireless device 303 is near the second wireless device 302, and the 3rd wireless device 303 sends Bluetooth address 305 by sound channel simultaneously.Second wireless device successfully passes the wireless MAC address that sound channel receives the 3rd wireless device, and the second wireless device can disconnect the connection 306 with the first wireless device, also can keep the connection with the first wireless device.For bluetooth, if the second wireless device and the 3rd wireless device do not set up pair relationhip, then pairing request the 307, three wireless device confirmation 308 initiated by the second wireless device.Connection request 309, second wireless device initiated by second wireless device and application connection 310 set up by the 3rd wireless device.Like this, the 3rd wireless device completes the connection with the second wireless device.
Fig. 4 is the schematic diagram of employing DTMF algorithm by transfer voice Mac address of example of the present invention.
DTMF is made up of group (fb) and high frequency group (fa) two class frequency signal, and each digital signal (comprises 697,770 by low frequency group, 852,941Hz) and high frequency group (1209,1336,1447,1633Hz) any one be formed by stacking.Further, the signal of its medium and low frequency group and high frequency group can be brought up to further and all be greater than 14KHz, exceeds the audibility range of common people like this, does not disturb the sensation of people, can reach better result of use.The coding and decoding definition of DTMF as shown in the figure, can be represented by the formula: f (t)=A_{a}sin (2f_{a}t)+A_{b}sin (2f_{b}t)).In formula, two represent the value of low, high tone cluster respectively, Ab and Aa represents that the sample value of low tone cluster and high tone cluster quantizes baseline respectively, and both Amplitude Ration are K=Ab/Aa (0.7<K<0.9).Corresponding to the nominal frequency in table 1 when sending, the frequency departure of dtmf signal is no more than 1.5%, the pickup electrode limit of bits per inch word is greater than 40ms, and receiving equipment can reliably receive the deviation of 2%, can normally receive the signal of 30ms ~ 40ms duration.Dtmf signal be get in employing 82 mode, from height two sound groups, respectively get an audio frequency be composited and represent 16 symbols, harmonic relationships is there is not between each frequency of these 8 audio signals, greatly reduce the interference of spurious signal, thus particularly antijamming capability is very strong for dtmf signal functional reliability.In the present invention, 16 symbol definitions are that 0 of 16 binary digits arrive F.The MAC Address of such bluetooth 6 bytes, such as 00:01:02:0A:0B:0C, can pass through 12 16 binary digits ' 0-0-0-1-0-2-0-A-0-B-0-C ', be loaded as dtmf signal sequence, be transferred to opposite end.
Fig. 5 is the schematic diagram based on 14KHz to 18KHz transfer voice Mac address of example of the present invention.
This example is easy to realize, and is regular coding by fixed Frequency Assignment, and here, each frequency is from 14000Hz to 17750Hz, and respectively corresponding hexadecimal digit 0 is to F, and the duration that each numeral takies 30 to 40ms can normally receive, the vacant 20ms in adjacent signals centre.The MAC Address of such bluetooth 6 bytes, such as 00:01:02:0A:0B:0C, by the tonic train of 12 16 binary digits ' 0-0-0-1-0-2-0-A-0-B-0-C ' correspondences, can be transferred to opposite end, opposite end identifies corresponding frequencies frequency, instead can solve Bluetooth address.The method is easier than Fig. 4 method is subject to ambient noise interference, can increase check code, improve anti-interference.
Should be appreciated that above-mentioned explanation is for showing the present invention, but do not limit the scope of the invention.
