Referring to fig. 2, a pairing method of a data transmission module according to an embodiment of the present invention includes:
step 201, the local data transmission module sends a simulation pairing request signal to the sound production module. It should be noted that, as shown in fig. 3, it is assumed that the opposite-end data transmission module 14 and the local-end data transmission module 11 are respectively located in two different devices, the local-end data transmission module 11 is located in the device 1, the opposite-end data transmission module 14 is located in the device 2, other parts of the device where the local-end data transmission module 11 and the local-end data transmission module 11 are located may be connected through a serial port, other parts of the device where the local-end data transmission module 11 is located may generate a Digital pairing request signal, and transmit the Digital pairing request signal to the local-end data transmission module 11 through the serial port, and the local-end data transmission module 11 has a Digital-to-Analog conversion function, for example, a DAC (Digital-to-Analog Converter) is arranged in the local-end data transmission module 11, and converts the Digital pairing request signal into an Analog pairing request signal, thereby sending the Analog pairing request signal to the sound production module 12. The digital pairing request signal is a pairing request carried in a digital signal form, the analog pairing request signal is a pairing request carried in an analog signal form, the digital pairing request signal includes related information required for pairing the local terminal data transmission module 11 and the opposite terminal data transmission module 14, and both the analog pairing request signal directly converted by the digital pairing request signal and the audio pairing request signal indirectly converted by the digital pairing request signal include related information required for pairing the local terminal data transmission module 11 and the opposite terminal data transmission module 14. The local data transmission module 11 may be configured according to the related information in the digital pairing request signal, so that the pairing can be completed in the subsequent process.
In step 202, the sound generation module receives the analog pairing request signal, converts the analog pairing request signal into an audio pairing request signal, and sends the audio pairing request signal to the sound receiving module 13. The sound emitting module 12 is a device capable of converting an analog signal into an audio signal and emitting sound, so that an audio pairing request signal can be emitted. The audio pairing request signal is a pairing request carried by an audio signal.
In step 203, the sound receiving module receives the audio pairing request signal, converts the audio pairing request signal into an analog pairing request signal, and sends the analog pairing request signal to the peer data transmission module 14. The sound receiving module 13 is a device capable of receiving an audio signal and converting the audio signal into an analog signal, so as to receive an audio pairing request signal sent by the sound emitting module 12 and convert the audio pairing request signal into an analog pairing request signal.
In step 204, the peer-to-peer data transmission module receives the analog pairing request signal. It should be noted that the peer-to-peer data transmission module 14 has an Analog-to-digital conversion function, for example, an ADC (Analog-to-digital Converter) is arranged in the peer-to-peer data transmission module 14, and converts the Analog pairing request signal received from the sound receiving module 13 into a digital pairing request signal. As shown in fig. 3, the peer data transmission module 14 and the other parts of the device where the peer data transmission module 14 is located may be connected through a serial port, and the peer data transmission module 14 transmits the digital pairing request signal to the other parts of the device where the local data transmission module 11 is located through the serial port. After receiving the analog pairing request signal, the peer data transmission module 14 can configure the peer data transmission module 14 according to the related information required for pairing the local data transmission module 11 and the peer data transmission module 14 included in the analog pairing request signal.

Further, the audio pairing request signal in the above embodiment may be a Dual Tone Multi Frequency (DTMF) audio signal, which is a method for representing numbers by different tones of sound, and is often used as a user signaling for sending a called number between a telephone and an exchange in a telephone system. Specifically, the dual-tone dual-frequency uses a sinusoidal signal with a higher frequency to be superimposed with a sinusoidal signal with a lower frequency, so as to generate a sound with tones, the sounds with different tones representing different characters (including numbers, letters, etc.), for example, the number "4" may be represented by a sound generated by superimposing two sinusoidal signals with frequencies of 770Hz and 1209Hz, respectively, and the number "3" may be represented by a sound generated by superimposing two sinusoidal signals with frequencies of 697Hz and 1477Hz, respectively. The audio pairing request in the embodiment of the present invention includes a plurality of sounds having tones. Because the dual-tone dual-frequency high-frequency group (i.e., the frequency that the sinusoidal signal with the higher frequency can select) includes 4 frequencies, and the dual-tone dual-frequency low-frequency group (i.e., the frequency that the sinusoidal signal with the lower frequency can select) also includes 4 frequencies, 16 sounds with different tones can be obtained by using the dual-tone dual-frequency, the 16 sounds with different tones can respectively correspond to the numbers "0-9", and the letters "a", "B", "C", "D", and the symbols "", "#", and the embodiment of the present invention can use the 16 sounds with different tones to form the audio pairing request signal.
Because the audio pairing request signal and the analog pairing request signal can be mutually converted, the audio pairing request signal and the analog pairing request signal contain the same information, the signal frame corresponding to the analog pairing request signal and the signal frame corresponding to the audio pairing request signal all comprise a frame header, a channel number (hereinafter referred to as the channel number) for the local data transmission module and the opposite end data transmission module to communicate, an address of the local data transmission module, an address and a frame tail of the opposite end data transmission module, the channel number, the address of the local data transmission module and the address of the opposite end data transmission module are all related information required for pairing of the local data transmission module 11 and the opposite end data transmission module 14, the local data transmission module 11 can configure itself according to the channel number and the address of the local data transmission module, the opposite end data transmission module 14 can configure itself according to the channel number and the address of the opposite end data transmission module, after the local terminal data transmission module 11 and the opposite terminal data transmission module 14 are both configured successfully, pairing is completed, and the local terminal data transmission module 11 and the opposite terminal data transmission module 14 can communicate with each other. The frame head and the frame tail may be marked with "#" and "#", the channel number, the address of the local data transmission module 11, and the address of the opposite data transmission module 14 may be represented by numbers, and the specific number of bits is not limited herein. For example, as shown in table one, the audio pairing request signal is a dual-tone multi-frequency audio signal, the frame header in the signal frame corresponding to the dual-tone multi-frequency audio signal is "#", the channel number is 05, the address of the local data transmission module is 1234, the address of the opposite data transmission module is 5678, and the frame tail is "#".
Watch 1
| Frame header | Channel number | Address of local data transmission module 11 | Address of peer data transfer module 14 | Frame end |
| * | 05 | 1234 | 5678 | # |
In order to prevent the audio pairing request signal from being affected and causing errors in the transmission process, the signal frame corresponding to the analog pairing request signal and the signal frame corresponding to the audio pairing request signal all include check codes for checking whether the analog pairing request signal or the audio pairing request signal is correct, and a generation strategy of the check codes may be set according to a specific working scenario, which is not limited herein. For example, as shown in table two, the audio pairing request signal is a dual-tone multi-frequency audio signal, the frame header in the signal frame corresponding to the dual-tone multi-frequency audio signal is "#", the channel number is "05", the address of the local data transmission module is "1234", the address of the opposite data transmission module is "5678", the frame tail is "#", the check code is generated according to the rule that the channel number, the address of the local data transmission module and the address of the opposite data transmission module are added, and if 0+5+1+2+3+4+5+6+7+8 is 41, the verification code is "41".
Watch two
In order to prevent confusion among the channel number, the address of the local end data transmission module, the address of the opposite end data transmission module and the check code, the signal frame corresponding to the analog pairing request signal and the signal frame corresponding to the dual-tone multi-frequency audio signal both include a separator for separating one or more components in the signal frame, for example, as shown in table three, a separator "a" is provided between the channel number and the address of the local end data transmission module, a separator "B" is provided between the address of the local end data transmission module and the address of the opposite end data transmission module, and a separator "C" is provided between the address of the opposite end data transmission module and the check code. It should be noted that the number of the delimiters in the signal frame corresponding to the analog pairing request signal and the signal frame corresponding to the audio pairing request signal may be one or more, and when there are a plurality of delimiters, the plurality of delimiters may be the same or different, but in order to ensure that the components can be clearly distinguished, it is preferable to provide a plurality of different delimiters.
Watch III
It should be noted that, after receiving the dual-tone multi-frequency audio signal, the sound receiving module 13 converts the dual-tone multi-frequency audio signal into an analog pairing request signal and sends the analog pairing request signal to the opposite-end data transmission module 14, and the opposite-end data transmission module 14 can analyze the analog pairing request signal, so as to obtain information represented by each component in the analog pairing request signal.
Referring to fig. 4, step 202 in the above embodiment can be specifically subdivided into step 2021 and step 2022, which are specifically as follows:
in step 2021, the sound generation module receives the analog pairing request signal and converts the analog pairing request signal into an audio pairing request signal. For the related description of step 2021, please refer to the description of step 202 in the above embodiments, which is not repeated herein.
At step 2022, the sound generation module periodically sends the audio pairing request signal to the sound reception module. In the above situation, it is necessary for the sound generating module 12 to periodically send an audio pairing request signal to the sound receiving module 13 to ensure that the peer data transmission module 14 can receive a correct audio pairing request signal, because there may be a case that the sound receiving module 13 does not receive the audio pairing request signal, or the sound receiving module 13 receives an audio pairing request signal that is wrong in the transmission process.
Referring to fig. 5, in order to ensure that the pairing process is completed only when the peer data transmission module receives the correct audio pairing request signal, steps 205 to 207 may be added after step 204, which includes the following specific contents:
in step 205, the peer-to-peer data transmission module detects whether the check code in the analog pairing request signal indicates that the analog pairing request signal is correct. In the transmission process of the audio pairing request signal or in the conversion process of the analog pairing request signal, a check code, a channel number, an address of the local data transmission module and/or an address of the opposite-end data transmission module may be wrong, which may cause that the analog pairing request signal received by the opposite-end data transmission module 14 is wrong, in order to avoid that the local data transmission module 11 and the opposite-end data transmission module 14 cannot be paired due to the above-mentioned error condition, the opposite-end data transmission module 14 detects the check code in the pairing request signal, so as to know whether the analog pairing request signal is correct.
In step 206, if the check code in the analog pairing request signal indicates that the analog pairing request signal is correct, the peer data transmission module sends a response pairing signal to the home data transmission module. For example, as shown in table three, if the channel number of the audio pairing request signal is erroneously changed to "02" during transmission, the channel number in the converted analog pairing request signal is also erroneously changed to "02", the opposite-end data transmission module 14 receives the analog pairing request signal with an error, and according to the check code generation rule, the check code should be 0+2+1+2+3+4+5+6+7+8, or 38, however, the check code in the analog pairing request signal received by the peer data transmission module 14 is "41", that is, the check code does not match the sum of the channel number, the address of the local data transmission module and the address of the peer data transmission module, therefore, the check code in the analog pairing request signal is judged to indicate that the analog pairing request signal is incorrect; and if the check code is consistent with the sum of the channel number, the address of the local end data transmission module and the address of the opposite end data transmission module, judging that the check code in the analog pairing request signal represents that the analog pairing request signal is correct.
When the check code in the analog pairing request signal indicates that the analog pairing request signal is correct, the opposite-end data transmission module 14 sends a response pairing signal to the local-end data transmission module 11, so that the local-end data transmission module 11 knows that the opposite-end data transmission module 14 has received the analog pairing request signal sent by the local-end data transmission module 11, and the pairing is successful.
And step 207, the local data transmission module receives the response pairing signal and controls the generation module to stop sending the audio pairing request signal to the sound receiving module periodically. The local data transmission module 11 receives the response pairing signal sent by the opposite data transmission module 14, and knows that the opposite data transmission module 14 has received the analog pairing request signal sent by the local data transmission module 11, and the pairing is successful, because the local data transmission module 11 and the opposite data transmission module 14 have been successfully paired, the sound generation module 12 does not need to continuously send the audio pairing request signal to the sound reception module 13, and therefore the sound generation module 12 is controlled to stop sending the audio pairing request signal to the sound reception module 13 periodically.
Referring to fig. 1, an embodiment of the present invention provides a pairing system 10 for a data transmission module, including a local end data transmission module 11, a sound production module 12 connected to the local end data transmission module 11, an opposite end data transmission module 14, and a sound receiving module 13 connected to the opposite end module; the local data transmission module 11 is configured to send a simulation pairing request signal to the sound generation module 12; the sound generation module 12 is configured to receive the analog pairing request signal, convert the analog pairing request signal into an audio pairing request signal, and send the audio pairing request signal to the sound receiving module 13; the sound receiving module 13 is configured to receive the audio pairing request signal, convert the audio pairing signal into an analog pairing request signal, and send the analog pairing request signal to the opposite-end data transmission module 14; the peer data transmission module 14 is configured to receive the analog pairing request signal.
