The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of a bluetooth watch, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include an operating system, a signal processing module, a signal encryption module, a signal transmission module, and a talkback voice transceiving program, wherein the signal processing module may be further subdivided into a first signal conversion module and a second signal conversion module.
In the bluetooth watch shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the bluetooth watch of the present invention may be disposed in the bluetooth watch, and the bluetooth watch calls the talkback voice transceiving program stored in the memory 1005 through the processor 1001, and executes the talkback voice transceiving method provided by the embodiment of the present invention.
Based on the above hardware structure but not limited to the above hardware structure, the present invention provides a first embodiment of a method for transceiving intercom voice. Referring to fig. 2, fig. 2 is a flowchart illustrating a talkback voice transceiving method according to a first embodiment of the present invention.
In this embodiment, the method is applied to a first bluetooth watch, the first bluetooth watch is connected to a first bluetooth headset and a second bluetooth watch, and the method includes:
step S201, if a first voice radio signal sent by the first Bluetooth headset is received, converting the first voice radio signal into a first voice analog signal;
in this embodiment, the execution main part is a first bluetooth watch, each bluetooth watch has a bluetooth headset matched with the execution main part, the bluetooth headset is connected with the bluetooth watch through bluetooth, and a first bluetooth headset is matched with the first bluetooth watch. In practical application, when a user speaks, the first bluetooth headset receives a first voice analog signal of the user, converts the first voice analog signal into a corresponding first voice radio signal, namely a bluetooth signal, and then sends the first voice radio signal to the first bluetooth watch, and after the first bluetooth watch receives the first voice radio signal, the first bluetooth watch is only suitable for short-distance propagation, and is easy to be interfered by the outside world and eavesdropped and divulged secretly during long-distance propagation, so that the first bluetooth headset first converts the first voice analog signal into a corresponding first voice analog signal in order to facilitate subsequent transmission and encryption.
It should be emphasized that the references to "first" and "second" in this and subsequent embodiments are merely used to distinguish similar objects, and do not refer to a bluetooth watch or a bluetooth headset, and may be interchanged where appropriate.
Step S202, converting the first voice analog signal into a first voice digital signal;
in the conventional intercom method, an intercom is often used for making an intercom call, but the intercom often uses a free frequency band, so that the use amount is large and the anti-interference performance is weak. Compared with the analog signal, the binary code, i.e. the digital signal, is less affected by noise, so that the obtained first voice analog signal can be converted into a corresponding first voice digital signal by a code modulation method.
Specifically, a quality indication value, namely a CQI value, of a channel may be detected, a current signal-to-noise ratio is obtained according to a mapping relationship between the CQI value and the signal-to-noise ratio, then a block error rate of signal transmission is counted, a signal-to-noise ratio offset is adjusted according to the block error rate, the current signal-to-noise ratio and the adjusted signal-to-noise ratio offset are added to obtain an equivalent signal-to-noise ratio, and finally, a corresponding code modulation mode is obtained according to the equivalent signal-to-noise ratio, wherein different code modulation modes correspond to different modulation orders. It should be noted that, generally, the higher the CQI value is, the better the quality of the channel is, the higher the selectable modulation order is, the greater the transmission throughput is, but the CQI value itself has no strict detection standard, so that an error or an error may occur in the obtained detection value, which inevitably causes inaccuracy in subsequent processing, so that, in order to select a code modulation method more accurately, on the basis of the CQI detection, a block error rate and an offset of a signal-to-noise ratio are also introduced to comprehensively consider, the error can be reduced to the maximum extent, and a more accurate code modulation method can be obtained, so that on one hand, it can be ensured that a signal can be transmitted by selecting the maximum throughput, which is the highest order; on the other hand, the situation that the anti-interference capability of the signal is reduced due to overlarge level selection can be avoided. Specifically, 16QAM, 64QAM, or the like may be selected for modulation.
Step S203, encrypting the first voice digital signal to obtain a first voice encrypted signal;
when the traditional interphone is used for talkback calling, the interphone generally does not have an encryption function, and a large number of interphones are used in a public free frequency band, so that the interphone is easy to eavesdrop and leak secret during signal transmission. Therefore, in order to ensure the security of signal transmission during the talkback process, the obtained first voice digital signal needs to be encrypted before formal signal transmission to obtain a first voice encrypted signal, and specifically, the encryption process may be performed in any manner that can be used for digital signal encryption, such as a key algorithm, a one-way hash algorithm, and the like.
Step S204, the first voice encryption signal is sent to the second Bluetooth watch, so that the second Bluetooth watch obtains the first voice analog signal according to the first voice encryption signal, and voice in the first voice analog signal is played through a second Bluetooth earphone connected with the second Bluetooth watch.
After the first voice encryption signal is obtained, the signal is modulated in a proper coding modulation mode and encrypted, so that the signal is not easily influenced by factors such as external noise in the transmission process and is also not easily eavesdropped to cause leakage, and the first voice encryption signal can be sent to a second Bluetooth watch, namely a target receiving end. Similarly, the second bluetooth watch is also equipped with a corresponding second bluetooth headset, and the second bluetooth watch can correspondingly process the signal after receiving the signal and then play the voice in the signal through the second bluetooth headset.
In the embodiment, the voice receiving and sending and the talkback calling can be completed through the portable earphone and the watch, a relatively large interphone is not needed, and the carrying is convenient; moreover, an appropriate coding modulation mode is selected to convert the original analog signal into a corresponding digital signal, so that the anti-interference capability of the signal can be greatly enhanced while the signal transmission throughput is ensured; besides, signals are encrypted, and the safety of signal transmission is effectively guaranteed.
Further, as an embodiment, referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the talkback voice transceiving method of the present invention, where the method further includes:
step S301, if a second voice encryption signal sent by the second Bluetooth watch is received, a second voice analog signal is obtained according to the second voice encryption signal;
in order to successfully complete the talkback call, the first bluetooth watch can send the voice signal to the second bluetooth watch, and correspondingly, the first bluetooth watch can also receive the voice signal sent by the second bluetooth watch. Similarly, for any bluetooth watch, it can complete the above processing of signals, and send after finally obtaining an encrypted signal. Therefore, in this embodiment, the first bluetooth watch can receive the signal sent by the second bluetooth watch, and the signal is an encrypted second voice encryption signal, so to play the voice therein, a corresponding second voice analog signal is to be obtained.
In a specific embodiment, referring to fig. 4, fig. 4 is a detailed flowchart of the step S301 in fig. 3, where the obtaining a second speech analog signal according to the second speech encrypted signal includes:
step A10, decrypting the second voice encrypted signal to obtain a second voice digital signal;
it can be understood that the second voice encryption signal is sent by the second bluetooth headset after the collected second voice analog signal is sent to the second bluetooth watch in a radio mode, and the second bluetooth watch sends the second voice analog signal after the second voice analog signal is subjected to corresponding processing such as coding modulation and encryption. The specific manner is consistent with the related steps and description in the first embodiment, and is not described herein again. Therefore, the second voice encrypted signal is decrypted through a decryption mode corresponding to the encryption mode to obtain a second voice digital signal.
Step a20, converting the second voice digital signal into the second voice analog signal;
since the earphone plays analog signals, the second voice digital signals also need to be converted into corresponding second voice analog signals. Specifically, the demodulation can be performed by using DPSK, MSK, or the like.
Step S302, converting the second voice analog signal into a second voice radio signal;
each Bluetooth watch is connected with the Bluetooth earphone matched with the Bluetooth watch through Bluetooth, and the Bluetooth watch and the Bluetooth earphone can transmit signals through Bluetooth signals, namely radio signals. Therefore, in order to send the voice signal to the bluetooth headset for playing, the obtained second voice analog signal needs to be converted into a second voice radio signal.
Step S303, sending the second voice radio signal to the first Bluetooth headset, so that the first Bluetooth headset obtains the second voice analog signal according to the second voice radio signal, and playing voice in the second voice analog signal.
After the second voice radio signal is obtained, the second voice radio signal can be sent to the corresponding first Bluetooth headset, and the first Bluetooth headset can restore the second voice radio signal into a second voice analog signal and play the second voice analog signal.
In this embodiment, the bluetooth watch may decrypt and demodulate the encrypted signal after receiving the encrypted signal containing the voice information, and restore the encrypted signal to the original analog signal, so as to be subsequently played in the earphone.
Further, as an embodiment, referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of the talkback voice transceiving method of the present invention, where the method further includes:
step S501, monitoring the self working state and the voice signal receiving and sending state of the first Bluetooth watch in real time;
the first Bluetooth watch has different working states, which specifically comprise a power-off state, a sleep standby state, a working state and the like; the voice signal transceiving conditions also have different states, which specifically include: signal transmission success, signal transmission failure, signal reception success, signal reception failure, and the like. The relevant status information changes in real time according to the actual situation, so that the status information needs to be monitored in real time.
Step S402, displaying the self working state and the voice signal transceiving state through a user interaction interface.
Each watch is provided with a display screen, a user interaction interface is arranged in each display screen, all the state information can be displayed through the user interaction interface, and a user can receive the information and perform corresponding operation according to the requirement. For example, when the watch is in a sleep standby state, a user can wake up the watch to enter a working state through any voice, such as "start up" and the like, and then record the required voice by using the earphone; for another example, after the voice input is successful, the user can select to confirm the transmission or re-input, and if the time length which is not selected by the user reaches the preset time length threshold value, the voice signal is directly transmitted; as another example, when the signaling fails, the user may choose to resend or re-enter the retransmission or abort the transmission.
In the embodiment, the working state information and the signal transmission state information can be monitored in real time, the information can be displayed on the user interaction interface, a user can check various state information at any time and perform corresponding operation according to the requirement of the user, the checking by the user is facilitated, the diversity of user selection and the flexibility of operation are increased, and particularly when transmission abnormity occurs, the information can be timely fed back to the user and timely processed according to a user instruction.
Referring to fig. 6, fig. 6 is a schematic flowchart of a fourth embodiment of the talkback voice transceiving method of the present invention, which is used for a first bluetooth headset connected to a first bluetooth watch, and the method includes:
step S601, if a first voice analog signal of a user is received, denoising the first voice analog signal to obtain a denoised first voice analog signal;
in this embodiment, the execution main body is a first bluetooth headset, and the first bluetooth headset can receive a voice, i.e., a first voice analog signal, sent by a user in real time. Because a user may send out a voice in any scene, interference factors such as noise are inevitably mixed in the voice analog signal, and the interference factors inevitably affect the subsequent talkback quality, so that before subsequent operation, the first voice analog signal needs to be subjected to noise elimination. Specifically, the noise in the signal can be filtered by using a filter, and because the frequency of the voice signal sent by a person is generally far lower than that of the noise, the noise can be eliminated by using a low-pass filter or a band-pass filter, and specific filter parameters can be selected according to actual requirements; in addition, the noise can be eliminated through a noise elimination model obtained through training or a noise elimination algorithm obtained through machine learning.
Step S602, converting the denoised first voice analog signal into a first voice radio signal;
the first bluetooth headset and the first bluetooth watch can be directly in communication connection through bluetooth signals, that is, radio signals, so after the first voice analog signal after noise elimination is obtained, in order to send the first voice analog signal to the corresponding first bluetooth watch, the first voice analog signal needs to be converted into a corresponding first voice radio signal.
Step S603, sending the first voice radio signal to the first bluetooth watch, so that the first bluetooth watch obtains the first voice analog signal according to the first voice radio signal, and converts the first voice analog signal into a first voice digital signal and sends the first voice digital signal.
After the first voice radio signal is obtained, the first voice radio signal is sent to a corresponding first Bluetooth watch, and after the first Bluetooth watch receives the first voice radio signal, the first Bluetooth watch firstly restores the first voice radio signal into a first voice analog signal, then carries out coding modulation and encryption on the first voice analog signal, and then sends the first voice analog signal. The specific implementation of the code modulation and the encryption is consistent with the related description in the foregoing first embodiment, and will not be described again here.
In the embodiment, the voice information of the user can be received in real time through the earphone, and is correspondingly processed and sent, so that the user can directly speak without using an interphone or performing additional operation when the user needs to speak, and the talkback communication process of the user is simplified.
Further, as an embodiment, referring to fig. 7, fig. 7 is a schematic flow chart of a fifth embodiment of the talkback voice transceiving method of the present invention, where the method further includes:
step S701, if a second voice radio signal sent by the first Bluetooth watch is received, converting the second voice radio signal into a second voice analog signal;
the first Bluetooth headset can receive voice information of a user in real time, send the voice information through the first Bluetooth watch matched with the first Bluetooth headset, and receive a second voice radio signal sent by the first Bluetooth watch in real time. It will be appreciated that the voice signal is sent by another bluetooth watch, and the first bluetooth headset needs to play the voice information therein for the user to listen to. And after the first bluetooth watch receives the second voice encryption signal sent by the second bluetooth watch, the first bluetooth watch decrypts and demodulates the signal to obtain a second voice analog signal, and the specific implementation manner is consistent with the foregoing and is not repeated herein. And then converting the second voice analog signal into a corresponding second voice radio signal and sending the second voice radio signal to the first Bluetooth headset, and then restoring the second voice radio signal into the second voice analog signal by the first Bluetooth headset.
Step S702, carrying out denoising processing on the second voice simulation signal;
because a user may send out a voice in any scene, interference factors such as noise are inevitably mixed in the voice analog signal, and the voice signal is also inevitably interfered in the transmission process, which inevitably affects the playing quality of the voice, so that before the voice playing, the second voice analog signal needs to be denoised. The specific denoising method is the same as the related description of step S601 in the fourth embodiment, and is not described herein again.
Step S703, playing the voice in the second voice analog signal.
After the above-mentioned relevant steps, get the original second voice analog signal, and also filtered the interference factor such as noise among them, so can broadcast the voice in this analog signal at this moment for users to listen to.
In this embodiment, when receiving the voice radio signal that corresponds wrist-watch and send, can convert this voice radio signal into corresponding voice analog signal, then play pronunciation wherein after removing noise to voice analog signal, not only guaranteed the quality of pronunciation, improved user's listening experience, still can make the user can both receive voice information at the very first time anytime and anywhere, avoided probably because the intercom is not nearby or not paying attention to intercom information and the lou of leading to in the traditional mode when using the intercom.
Furthermore, in an embodiment, the present application further provides a computer storage medium having a computer program stored thereon, where the computer program is executed by a processor to implement the steps of the method in the foregoing method embodiments.
