Detailed Description
Referring to fig. 1, fig. 1 is a schematic flowchart of a bluetooth pairing connection method according to an embodiment of the present invention, where the method is applied to a bluetooth device, and includes:
step 11: sending a broadcast data packet to the outside, wherein the broadcast data packet comprises address information of the Bluetooth equipment;
wherein the address information of the Bluetooth device uniquely corresponds to the Bluetooth device. The uniqueness of the address information of the bluetooth device enables the terminal to determine which bluetooth device to automatically connect with.
Step 12: generating a pairing carrier signal based on the address information, the awakening identification code and a preset carrier signal of the Bluetooth device;
the preset carrier signal may be an electromagnetic wave signal or an acoustic wave signal. The awakening identification code is used for indicating the terminal to start the Bluetooth and is confirmed by negotiation between the terminal and the Bluetooth equipment. And the pairing carrier signal is used for starting Bluetooth under the condition that the terminal identifies the awakening identification code.
Step 13: and sending the pairing carrier signal to the outside.
And the pairing carrier signal is used for determining whether to carry out pairing connection with the Bluetooth equipment according to the address information of the Bluetooth equipment in the broadcast data packet and the address information of the Bluetooth equipment in the pairing carrier signal under the condition that the terminal starts the Bluetooth.
According to the Bluetooth pairing connection method provided by the embodiment of the invention, the terminal can automatically judge whether to perform pairing connection with the Bluetooth equipment or not by sending the broadcast data packet and the pairing carrier signal, manual operation of a user is not required, the intelligent degree is high, the method is more convenient and faster, and the time of the user is saved.
In the above embodiment, the bluetooth device may be a bluetooth headset, a bluetooth speaker, or a bluetooth car.
Because the energy consumption of the sound wave is low, in the sound waves with different frequencies, the audible sound wave signal can cause sound pollution, and a large number of sound sources exist in the audible sound wave signal, so that great interference exists; the inaudible ultrasonic signal has strong directivity, and a blind area exists in the propagation process, so that the receiving end cannot receive the signal.
Therefore, preferably, the preset carrier signal is a preset infrasonic wave carrier signal.
Therefore, the generated pairing carrier signal is an infrasonic wave signal, sound interference cannot be caused during propagation, the propagation effect is better, and energy consumption is further saved.
In the embodiment of the invention, the frequency of the preset infrasonic wave carrier signal is less than 20 Hz. The frequency of the preset infrasonic wave carrier signal can be set according to actual requirements, and the method is more flexible and convenient.
In some preferred embodiments of the present invention, the wakeup identification code for instructing the terminal to start bluetooth may be set by itself according to actual requirements, but the wakeup identification code must be recognized by both the bluetooth device and the terminal in a unified manner, so that automatic pairing connection between the bluetooth device and the terminal can be realized.
Preferably, the wakeup identification code for indicating the terminal to start the bluetooth uniquely corresponds to both the bluetooth device and the terminal. Therefore, when the terminal and the Bluetooth equipment are connected in a pairing mode, the workload can be reduced, the response is quicker, and the energy consumption is saved.
For example, the wake-up identification code between the handset a and the Bluetooth headset a in the same series is "a _ open _ Bluetooth", and the wake-up identification code "a _ open _ Bluetooth" corresponds to only the handset a and the Bluetooth headset a in the series. Therefore, when the series of mobile phones A and the Bluetooth earphones a are connected in a pairing mode, the connection efficiency can be further improved.
In the embodiment of the present invention, the paired carrier signal may be generated in various ways.
As a preferred embodiment, the step of generating the paired carrier signal includes: generating an original signal based on the address information and the awakening identification code of the Bluetooth equipment; loading the original signal on a preset infrasonic wave carrier signal sent by a carrier signal generator of the Bluetooth equipment to generate a synthesized sonic wave signal; and amplifying the synthesized sound wave signal to generate a matched carrier signal.
Specifically, a carrier signal generator of the bluetooth device sends out a preset infrasonic wave carrier signal P1 #; generating an original signal P2# according to the Address information # Address _01 of the Bluetooth device and an awakening identification code for indicating the terminal to start Bluetooth; recoding and converting the carrier signal P1# and the original signal P2#, loading the original signal P2# on the carrier signal P1#, and generating a synthesized sound wave signal P3 #; and amplifying the synthesized sound wave signal P3# to generate a paired carrier signal P3_1 #.
Therefore, the existing components of the Bluetooth equipment are used for generating the pairing carrier signals, and the cost of the Bluetooth equipment is not required to be increased.
With the popularization of intelligent terminals and bluetooth devices, terminals and bluetooth devices are filled everywhere in living space, and in order to reduce the workload of the terminals and the bluetooth devices and improve the efficiency of pairing connection, in the embodiment of the invention, the distance between the bluetooth devices and the terminals can be set to be smaller than or equal to a specified distance threshold. According to the sound pressure level attenuation relation of the infrasonic wave signals propagating in the space, when the distance between the Bluetooth device and the terminal is smaller than or equal to a specified distance threshold value, the sound pressure level attenuation of the infrasonic wave is smaller than or equal to a preset threshold value.
Therefore, preferably, the sound pressure level of the pairing carrier signal is higher than the sound pressure level of the current environment of the bluetooth device, and the difference between the sound pressure level of the pairing carrier signal and the sound pressure level of the current environment of the bluetooth device is smaller than or equal to a preset threshold. Therefore, the terminal receives the pairing carrier signal sent by the Bluetooth device, the distance between the terminal and the terminal is smaller than or equal to the designated distance threshold, the workload of the terminal is greatly reduced, and the efficiency of pairing connection is improved.
Preferably, the sound pressure level of the current environment of the bluetooth device is obtained by a microphone module of the bluetooth device. The sound pressure level of the current environment of the Bluetooth device is obtained through the existing microphone module of the Bluetooth device, the Bluetooth device does not need to be added on hardware, and the cost of the Bluetooth device does not need to be increased.
For example, when the distance threshold is 50cm and the distance between the bluetooth device and the terminal is less than or equal to 50cm, the sound pressure level attenuation of the infrasonic wave is less than or equal to 10 dm. In the embodiment of the present invention, the energy requirement of the paired carrier signal P3_1# may be set to be 10dB higher than the background noise of the environment where the bluetooth device is located, the sound pressure level of the background noise of the environment where the bluetooth device is currently located, which is obtained through analysis by the bluetooth device microphone module, is denoted as Lp, and the sound pressure level of the paired carrier signal P3_1# may be set to be Lp +10 dB.
In some preferred embodiments of the present invention, after the step of sending the paired carrier signal outside the pair, the method further includes: receiving a pairing instruction sent by a terminal; and carrying out pairing connection with the terminal. Therefore, the Bluetooth equipment receives the pairing instruction, can be immediately paired and connected with the terminal, does not need a user to perform manual operation, and is sensitive in response and rapid in connection.
And the pairing instruction sent by the terminal is generated when the terminal determines to be paired and connected with the Bluetooth equipment.
That is to say, when the terminal determines to pair with the bluetooth device, the terminal sends a pairing instruction to the corresponding bluetooth device, and the bluetooth device receives the pairing instruction and performs pairing connection with the terminal.

step 21: receiving a pairing carrier signal sent by a Bluetooth device, wherein the pairing carrier signal comprises address information, a wake-up identification code and a preset carrier signal of the Bluetooth device;
the pairing carrier signal may be an electromagnetic wave signal or an acoustic wave signal. The address information of the bluetooth device uniquely corresponds to the bluetooth device that transmitted the address information. The uniqueness of the address information of the bluetooth device enables the terminal to determine which bluetooth device to automatically connect with. The awakening identification code for indicating the terminal to start the Bluetooth is confirmed by the terminal and the Bluetooth equipment in a negotiation way.
Step 22: based on the pairing carrier signal, a Bluetooth switch is turned on, and address information of the Bluetooth equipment is stored;
the terminal turns on a Bluetooth switch under the condition of recognizing the awakening identification code; in the case where the address information of the bluetooth device is detected, the address information is stored.
Step 23: receiving a broadcast data packet, wherein the broadcast data packet comprises address information of a Bluetooth device;
step 24: and under the condition that the address information of the Bluetooth equipment in the broadcast data packet is matched with the stored address information of the Bluetooth equipment, sending a pairing instruction to the Bluetooth equipment sending the broadcast data packet, and carrying out pairing connection with the Bluetooth equipment sending the broadcast data packet.
That is, the terminal matches the address information of the bluetooth device in the broadcast packet received in step 23 with the stored address information of the bluetooth device, and when the same address information is matched, determines that the bluetooth device corresponding to the address information is a bluetooth device to be paired and connected, outputs a pairing instruction, and performs pairing and connection with the bluetooth device that transmitted the broadcast packet.
According to the Bluetooth pairing connection method provided by the embodiment of the invention, whether the Bluetooth equipment is in pairing connection or not can be automatically judged by receiving the broadcast data packet and the pairing carrier signal, manual operation of a user is not needed, the intelligent degree is high, the method is more convenient and faster, and the time of the user is saved.
Preferably, the preset carrier signal is a preset infrasonic wave carrier signal.
That is to say, the pairing carrier signal is an infrasonic wave signal, so that sound interference cannot be caused during propagation, the propagation effect is better, and the energy consumption is further saved.
Preferably, the frequency of the preset infrasonic wave carrier signal is less than 20 Hz.
In the embodiment of the invention, the paired carrier signals can be detected in various modes.
As a preferred embodiment, the turning on the bluetooth switch based on the pairing carrier signal includes: decoding the matched carrier signal to restore an original signal, wherein the original signal comprises address information and an awakening identification code of the Bluetooth equipment; under the condition that the awakening identification code in the original signal is identified, a Bluetooth switch is turned on; and the terminal can receive the broadcast data packet sent by the Bluetooth equipment to the outside under the condition of turning on the Bluetooth switch.
Therefore, the terminal can automatically turn on the Bluetooth switch by decoding the pairing carrier signal under the condition of identifying the awakening identification code in the original signal, does not need manual operation of a user, is simple and convenient, and is also favorable for saving the energy consumption of the terminal.
Further, before decoding the paired carrier signal and restoring the original signal, the method further includes: and filtering audible sound wave signals and ultrasonic wave signals in the current environment of the terminal.
That is to say, the infrasonic wave signal is obtained by filtering the audible sound wave signal and the ultrasonic wave signal, so that the interference signal in the paired carrier signal is reduced, the workload of the terminal can be reduced, and the energy consumption of the terminal is further saved.
Specifically, the terminal receives a pairing carrier signal P3_1# sent by the Bluetooth device, analyzes the pairing carrier signal P3_1#, filters audible sound wave signals and ultrasonic wave signals in the environment, and obtains infrasonic wave signals; then, according to the frequency (for example, 10Hz) of the matched carrier signal, a synthetic sound wave signal P3# is correspondingly obtained; re-decoding the synthesized sound wave signal P3# to restore an original signal P2 #; analyzing the original signal P2#, opening a Bluetooth switch of the terminal under the condition that an awakening identification code (such as sn _ open _ Bluetooth) for indicating the terminal to start Bluetooth is identified, and storing Address information # Address _01 under the condition that the Address information # Address _01 of the Bluetooth device is checked; after a terminal starts Bluetooth, receiving broadcast data packets sent by Bluetooth equipment nearby the terminal, wherein the broadcast data packets carry address information of the Bluetooth equipment sending the broadcast data packets; decoding the received broadcast data packet, checking the address information of the Bluetooth equipment in the broadcast data packet, and performing matching analysis on the address information of the stored Bluetooth equipment; and when the same address information is matched, sending a pairing instruction, and automatically pairing and connecting with the Bluetooth equipment corresponding to the address information.
