Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 2, fig. 2 is a flowchart of an implementation of an acoustic wave receiving method according to an embodiment of the present invention, which is detailed as follows:
in step S201, the plurality of channels of the acoustic wave device respectively receive acoustic wave communication access information in a fixed frequency modulation manner, where the acoustic wave communication access information includes a plurality of preferred frequencies supported by the plurality of channels of the mobile terminal.
The number of the plurality of channels is not limited herein, and may be one channel, or may be two channels or a plurality of channels.
The format of the sound wave communication access information can be set by the user or default by the system. For example, the format of the sound wave communication access information is "0X 00,0X13,0X00,0X00,0X01, X1, X2, X3 …", where X1, X2, and X3 … XN are several preferred frequencies, and the number of preferred frequencies depends on the number of channels N.
The sound wave device is a device of the mobile terminal that can receive audio-based communication, for example, a sound wave KEY.
The fixed frequency modulation mode is to poll frequency points in a frequency table in sequence, and the channels select the frequency corresponding to the frequency points to receive the sound wave communication access information according to the frequency points.
And each channel is subjected to frequency modulation according to the frequency of the fixed frequency modulation to obtain the corresponding frequency.
For convenience of explanation, the number of three channels is taken as an example.
Referring to table 1, table 1 is a three-channel fm table for an acoustic wave device.
| Frequency band | Channel 1 | Channel 2 | Channel 3 |
| 1 | 16KHZ | 15KHZ | 14KHZ |
| 2 | 13KHZ | 12KHZ | 11KHZ |
| 3 | 10KHZ | 9KHZ | 8KHZ |
| 4 | 7KHZ | 6KHZ | 5KHZ |
The sound wave equipment carries out cyclic frequency modulation waiting by timing when waiting for receiving, and the frequency modulation graphs of three channels from high frequency are as follows: 16KHZ-15KHZ-14KHZ, 13KHZ-12KHZ-11KHZ, 10KHZ-9KHZ-8KHZ, 7KHZ-6KHZ-5 KHZ.
For example, when the polling frequency point is 1, the frequency modulation of the channel 1 obtains the corresponding frequency of 16KHZ, the frequency modulation of the channel 2 obtains the corresponding frequency of 15KHZ, the frequency modulation of the channel 3 obtains the corresponding frequency of 14KHZ, when the polling frequency point is 2, the frequency modulation of the channel 1 obtains the corresponding frequency of 13KHZ, the frequency modulation of the channel 2 obtains the corresponding frequency of 12KHZ, and the frequency modulation of the channel 3 obtains the corresponding frequency of 11 KHZ. The whole frequency band is traversed by the three-channel cyclic frequency modulation mode, so that the access time of the equipment can be effectively reduced.
In step S202, after receiving the acoustic wave communication access information, respectively establishing connections between the plurality of channels and the plurality of channels of the mobile terminal;
when the sound wave communication access information is received, the connection between the channels and the channels of the mobile terminal is respectively established through the frequency obtained by fixing frequency modulation of the channels of the sound wave equipment.
In step S203, extracting the preferred frequencies, and configuring the preferred frequencies as the transmitting frequencies and the receiving frequencies of the channels; the implementation process of configuring the preferred frequencies as the transmitting frequencies and the receiving frequencies of the channels is as follows:
x1, X2, and X3 … XN are several preferred frequencies, and are respectively configured as the frequencies of channel 1, channel 2, channel 3, and channel N.
For convenience of explanation, the number of three channels is taken as an example.
For example, when the acoustic wave device channel 1, channel 2, and channel 3 are in a fixed frequency modulation manner, when the tuning polling frequency point is 1, the frequency modulation of channel 1 obtains a corresponding frequency of 16KHZ, the frequency modulation of channel 2 obtains a corresponding frequency of 15KHZ, and the frequency modulation of channel 3 obtains a corresponding frequency of 14KHZ, if a plurality of received preferred frequencies are 9KHZ, 12KHZ, and 8KHZ, the 9KHZ is configured as the transmission frequency and the reception frequency of channel 1, the 12KHZ is configured as the transmission frequency and the reception frequency of channel 2, and the 8KHZ is configured as the transmission frequency and the reception frequency of channel 3. It should be noted that the preferred frequency is a frequency preferred by the mobile terminal in one channel. The mobile terminal may have several channels, and the mobile terminal may have multiple frequencies in one channel, for example, the mobile terminal may have a channel a, a channel B, and a channel C, where the channel a has three frequencies of a1, a2, and A3, if the preferred frequency is a2 frequency, the a2 frequency is the preferred frequency of the a channel, the channel B has three frequencies of B1, B2, B3, and B4, if the preferred frequency is B2 frequency, the B2 frequency is the preferred frequency of the B channel, the channel C has three frequencies of C1, C2, C3, and C4, and if the preferred frequency is C2 frequency, the C2 frequency is the preferred frequency of the C channel.
The preferred frequencies are configured to be the sending frequencies and the receiving frequencies of the channels, so that the problem that the stability of data transmission is low due to the fact that the frequency of the channel is often different from the preferred frequencies supported by the mobile terminal when the sound wave equipment adopts the frequency of the channel to communicate with the mobile terminal is solved, and the stability of the system is improved.
In step S204, the channels transmit acoustic wave communication response information with the configured transmission frequency;
the plurality of channels transmit acoustic wave communication response information by adopting configured transmission frequency, and specifically comprise:
each channel in the plurality of channels sends acoustic wave communication response information at a preferred frequency in the plurality of configured preferred frequencies; alternatively, the first and second electrodes may be,
and a preset channel in the plurality of channels sends acoustic wave communication response information at the configured preferred frequency.
In step S205, the processing thread of the acoustic wave communication access information is turned off to shield the acoustic wave communication access information.
And after the connection is successful, closing the processing thread of the sound wave communication access information, and closing the response to the sound wave communication access information until the communication of the current connection equipment is finished.
In the embodiment, by closing the processing thread of the sound wave communication access information, the data communication with only one mobile terminal at the same time is ensured, the communication conflict in the data communication process is solved, and the interference of the communication conflict when other equipment is accessed in the transmission process is greatly reduced.
Example two
The embodiment describes an implementation process of canceling shielding the acoustic wave communication access information after the processing thread of the acoustic wave communication access information is closed to shield the acoustic wave communication access information, and details are as follows:
detecting whether the connection is disconnected;
and when the connection is disconnected, recovering the processing thread of the sound wave communication access information to cancel shielding the sound wave communication access information.
In this embodiment, the acoustic wave device detects whether the connection is disconnected, and after the connection is disconnected, the processing thread of the acoustic wave communication access information is recovered to cancel shielding the acoustic wave communication access information. So that the sound wave equipment can respond to the sound wave communication to access information, and further can access other mobile terminals.

s301, configuring the frequency of a receiving channel by the sound wave equipment;
s302, if a mobile terminal is accessed, executing a step S304, otherwise executing a step S303;
s303, jumping to the next frequency point by the sound wave equipment;
s304, setting the frequency of the channel as the preferred communication frequency of the mobile terminal, and closing the processing thread of the sound wave communication access information;
s305, transaction communication.
Example four
Referring to fig. 4, fig. 4 is a flowchart of an implementation of a method for sending a sound wave according to an embodiment of the present invention, which is detailed as follows:
in step S401, a plurality of channels of the mobile terminal select a transmission frequency in a random frequency modulation manner, respectively;
the mobile terminal comprises a plurality of channels, wherein the channels of the mobile terminal respectively select a sending frequency in a random frequency modulation mode, and the method specifically comprises the following steps:
each channel of the mobile terminal acquires a random number from a pre-stored random number table;
selecting a frequency point according to the acquired random number;
selecting the frequency corresponding to the frequency point as the sending frequency of each channel in a pre-stored frequency table;
and the frequency table comprises the frequency points and the frequencies corresponding to the frequency points.
When the mobile equipment searches for access, signal transmission is carried out in a random frequency modulation mode, and the transmission frequency is modulated according to a random number table built in each mobile equipment.
And performing modulus operation on the random number according to the acquired random number to obtain a modulus value. For example, if the transmission band is 5KHZ to 16KHZ, the modulo value M obtained by modulo 12 by taking the random number X is X% 12, and the transmission frequency of the current channel is obtained from the table lookup of the modulo values.
For convenience of explanation, the number of three channels is taken as an example.
Referring to table 2, table 2 is a mobile terminal three-channel fm table.
For example, if the random numbers corresponding to the channels 1,2, and 3 are 0x34,0x67, and 0x5a, respectively, the lengths of the random number tables corresponding to the three channels are integer multiples of 3, so as to ensure that the correct frequency can be obtained for each frequency modulation. When the traversal of the random number table is completed, the mobile device chooses to exit or continue to perform a new round of sound wave key from the first number.
In this embodiment, because a random frequency modulation mode is adopted, and random frequencies are used for a plurality of channels, the probability that the frequency used by the plurality of channels is the same as the frequency used by the acoustic wave device for transaction transmission at the same time is very small, and therefore access interference generated when other mobile terminals are accessed in the transmission process is greatly reduced. If the transaction communication fails due to the same channels, the correctness and the integrity of the transmission are ensured by adopting a retransmission mode immediately.
In step S402, the channels respectively transmit acoustic communication access information using the selected transmission frequency, where the acoustic communication access information includes a plurality of preferred frequencies supported by the channels of the mobile terminal;
wherein the selected transmission frequency broadcasts acoustic communications access information.
In step S403, the channels respectively detect whether acoustic wave communication response information is received;
in step S404, if yes, stopping sending the acoustic wave communication access information, and respectively establishing connections between the plurality of channels and the plurality of channels of the acoustic wave device, and if not, continuing sending the acoustic wave communication access information;
in step S405, the supported preferred frequencies are configured as the transmission frequency and the reception frequency of the channels, respectively.
In this embodiment, the supported preferred frequencies are respectively configured as the transmitting frequency and the receiving frequency of the channels, so that after the mobile terminal is connected with the acoustic wave device, the stability of a communication link between the mobile terminal and the acoustic wave device is high.

s505, taking down a group of random numbers and jumping to a next group of frequency points;
s506, configuring the frequency band to be the preferred frequency band, and performing transaction communication.
