[0020] Bluetooth Low Energy (BLE) Mesh network is a wireless network based on Bluetooth low energy technology. BLE Mesh network consists of multiple nodes, each of which supports BLE communication. BLE Mesh network allows many-to-many connections and communications between numerous nodes. Each node can be a sender of information, a receiver of information, or a relay node for information transmission in the network. In this way, even if there is no direct radio communication link between two nodes, information can be relayed by other nodes in the network to ensure reliable transmission of information throughout the network.

[0021] The BLE Mesh network has the characteristic of low bandwidth and is mainly used for command control between low-power devices. That is, what is transmitted in the BLE Mesh is usually a small amount of control data or sensor data.

[0022] In view of this, an embodiment of the present application provides a control system. In the scheme of the embodiment of the present application, the control system includes: an audio input module, a control module, an audio processing module and a communication module. The communication module is connected to an audio playback device through a BLE Mesh network. Among them, the audio input module is used to obtain the first audio, and the control module is used to identify the first audio signal as an audio to be played or a voice command. When the first audio signal is the audio to be played, the audio processing module compresses the first audio signal to obtain a compressed first audio signal. Furthermore, the communication module sends the compressed first audio signal. Since the communication module is connected to the audio playback device through the BLE Mesh network, the audio playback device can receive the compressed first audio signal and play the first audio signal. In the above scheme, the audio processing module is used to compress the first audio signal to reduce the bandwidth requirement of audio transmission, so as to realize the transmission of audio data in the BLE Mesh network, thereby realizing audio transmission between low-power devices.

[0023] In order to make the above-mentioned purposes, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 1 Schematic diagram of a control system in an embodiment of the present application. Figure 1 As shown, the control system 1 may include: an audio input module 11 , a control module 12 , an audio processing module 13 , a communication module 14 and an interaction module 15 .

[0025] In a specific implementation, the control system 1 may be the sender of the signal.

[0026] Specifically, the audio input module 11 can be used to obtain a first audio signal, which can be an audio to be played or a voice command issued by a user. The audio to be played can be the user's voice, or can also be an audio file, such as music.

[0027] In one embodiment, the audio input module 11 may be a microphone, and the audio input module 11 may be used to collect audio signals of the user. That is, the control system 1 may be built with a microphone for audio collection.

[0028] In other embodiments, the control system 1 may also obtain audio signals from the outside.

[0029] In a possible implementation, the audio input module 11 can obtain a first audio signal from a user's terminal device. Exemplarily, the first audio signal can be music or broadcast, etc. Specifically, the user's terminal device can establish a communication connection with the control system 1 so that the audio input module 11 can obtain the audio signal of the user terminal.

[0030] Specifically, the user terminal and the control system 1 may be connected in a wired or wireless manner, for example, the user terminal and the control system 1 may be connected in a Universal Serial Bus (USB), Bluetooth, etc. The embodiment of the present application does not limit the connection method between the user terminal and the control system 1.

[0031] In another possible implementation, the audio input module 11 may obtain the first audio signal from a device equipped with a microphone, wherein the device equipped with a microphone may be an audio playback device, etc., but is not limited thereto.

[0032] In the solution of the embodiment of the present application, each control system can be associated with one or more users, and the audio input module can obtain the voice signal or voice command of the associated user, or can obtain the audio signal from the terminal device of the associated user. In a specific implementation, the user can register and bind the identity through the application installed on the terminal device to establish an association with the control system.

[0033] Furthermore, the audio input module 11 is connected to the control module 12. The audio input module 11 can transmit the first audio signal to the control module 12, and the control module 12 can be used to identify the first audio signal to determine that the first audio signal is an audio to be played or a voice command. Among them, the audio to be played refers to the audio that the user wants to play. The audio to be played can be the user's voice, or it can be music or broadcast transmitted by the user's terminal device. A voice command refers to a command to be executed issued by the user in the form of voice. For example, a voice command can be "turn on the speaker", "turn on the light", "turn off the speaker", "open the curtains", etc.

[0034] It should be noted that the embodiment of the present application does not limit the method by which the control module 12 identifies the first audio signal.

[0035] Furthermore, the control module 12 can be connected to the audio processing module 13. If the control module 12 recognizes that the first audio signal is the audio to be played, the control module 12 can transmit the first audio signal to the audio processing module 13, and the audio processing module 13 can compress the first audio signal to obtain a compressed first audio signal.

[0036] Exemplarily, the audio processing module 13 may include: an encoder for compressing the first audio signal. For example, the encoder may be an LC3 encoder or an SBC encoder. The LC3 encoder or the SBC encoder may be used to compress the first audio signal. The use of the LC3 encoder or the SBC encoder to compress the first audio signal can ensure the audio quality as much as possible while reducing the bandwidth requirement of the audio signal, so as to achieve real-time transmission of high-quality audio. In a specific implementation, the audio processing module 13 may also use other encoders other than the LC3 encoder or the SBC encoder to compress the audio signal, and this embodiment does not limit the compression method of the audio signal.

[0037] In a possible implementation, the audio processing module 13 may further perform noise reduction processing on the first audio signal before compressing the first audio signal. The noise reduction processing may include one or more of the following: acoustic echo cancellation (AEC), active noise control (ANC), and automatic gain control (AGC). Through the noise reduction processing, the effective signal in the first audio signal can be made clearer.

[0038] In one embodiment, the audio input module 11 can be connected to the audio processing module 13 ( Figure 1 (not shown), after the audio input module 11 obtains the first audio signal, the first audio signal can be transmitted to the audio processing module 13 for noise reduction processing. Further, after the noise reduction processing, the first audio signal is transmitted to the control module 12 for recognition. Such a solution is conducive to improving the accuracy of recognition.

[0039] Furthermore, the audio processing module 13 is connected to the communication module 14 , and the audio processing module 13 can transmit the compressed first audio signal to the communication module 14 .

[0040] In the solution of the embodiment of the present application, the control system 1 can be connected to one or more audio playback devices. In the solution of the embodiment of the present application, the audio playback device can be a low-power device. Exemplarily, the audio playback device can be a speaker.

[0041] Specifically, the communication module 14 can be connected to the audio playback device through the BLE Mesh network, and the communication module 14 can send the compressed first audio signal, and correspondingly, each audio playback device can receive the compressed first audio signal, so that each audio playback device can play the compressed first audio signal or the first audio signal. Figure 1As shown, the communication module 14 can be connected to the audio playback device A21 and the audio playback device B22 via a BLE Mesh network, so that the audio playback device A21 and the audio playback device B22 can play audio synchronously.

[0042] In a possible implementation, the audio playback device may directly play the compressed first audio signal.

[0043] In another possible implementation, the audio playback device may have a decompression capability. Exemplarily, the audio playback device may be configured with a decoder corresponding to the encoder in the audio processing module 13, and the decoder may decode the compressed first audio signal to restore the first audio signal, thereby being able to play the first audio signal.

[0044] Furthermore, in the solution of the embodiment of the present application, the control system 1 can also be connected to one or more controlled devices. Specifically, the communication module 14 can also be connected to each controlled device through a BLE Mesh network. Figure 1 As shown, the communication module 14 can be connected to the controlled device C31 and the controlled device D32 through the BLE Mesh network, so that the user can synchronously control the controlled device C31 and the controlled device D32.

[0045] Specifically, if the control module 12 recognizes that the first audio signal is a voice command, the control module 12 can convert the first audio signal into a control signal, and further transmit the control signal to the communication module 14, so that the communication module 14 sends the control signal. Since the communication module 14 is connected to each controlled device through the BLE Mesh network, each controlled device can receive the control signal and execute it, so that each controlled device can synchronously execute the voice command issued by the user.

[0046] In one embodiment, the controlled device may be a lamp, and the control signal may be used to control one or more of the on, off, brightness, and color of the lamp.

[0047] In a possible implementation, when the first audio signal is identified as the audio to be played, the control module 12 can also be used to generate a control signal based on the first audio signal, and the communication module 14 can send the control signal generated based on the first audio signal to each lamp, so that the color and / or brightness of each lamp is synchronously adapted to the audio to be played. Specifically, in the process of sending the compressed first audio signal to each audio playback device, the communication module 14 can synchronously send a control signal with the same timestamp to each lamp, so that the lighting effect of each lamp is synchronized with the played audio.

[0048] It should be noted that the controlled device may also be other types of devices, and this embodiment does not limit the type of the controlled device.

[0049] As a variation, the control system 1 can obtain control instructions from the user's terminal device. For example, the user can set the control instructions through an application installed on the terminal device. The terminal device further sends the control instructions to the control system 1. The control module 12 can convert the control instructions into control signals and then send the control signals to the controlled device through the communication module 14.

[0050] In a specific implementation, the control system 1 may be an independent device. Specifically, the control system 1 may be a device independent of the audio playback device, or the control system 1 may be a device independent of the controlled device. Alternatively, the control system 1 may be integrated on the audio playback device or integrated on the controlled device (such as a lamp).

[0051] In a specific implementation, the control system 1 can send the compressed first audio signal or control signal to other control systems, and the other control systems forward the compressed first audio signal or control signal to their respective connected audio playback devices or controlled devices.

[0052] Reference Figure 2 , Figure 2 It is a schematic diagram of an application scenario of a control system in an embodiment of the present application.

[0053] like Figure 2 As shown, control system 1, control system 2 and control system 3 can be connected through a BLE Mesh network. The specific structures of control system 2 and control system 3 can refer to the relevant description of control system 1 in this article, and will not be repeated here. For the sake of distinction, the user associated with control system 1 is recorded as the first user, the user associated with control system 2 is recorded as the second user, and the user associated with control system 3 is recorded as the third user.

[0054] Specifically, control system 1 can send a compressed first audio signal, control system 2 and control system 3 receive the compressed first audio signal through the BLE Mesh network, and control system 2 and control system 3 can send the compressed first audio signal to their respective connected audio playback devices for playback. Alternatively, the audio processing modules of control system 2 and control system 3 can decompress the compressed first audio signal to obtain the first audio signal, and then send the first audio signal to their respective connected audio playback devices for playback.

[0055] Specifically, control system 1 can send a control signal obtained based on the first audio signal, control system 2 and control system 3 receive the control signal through the BLE Mesh network, and control system 2 and control system 3 can send the control signal to their respective connected controlled devices to execute the voice commands issued by the user associated with control system 1.

[0056] In a specific implementation, the control system 1 may also be the receiver of the signal.

[0057] Combined with reference Figure 1 and Figure 2 , the communication module 14 can receive the compressed second audio signal through the BLE Mesh network. The second audio signal can be obtained by the audio input module of other control systems other than the control system 1. Exemplarily, the control system 2 can send the compressed second audio signal, and the communication module 14 of the control system 1 can receive the compressed second audio signal through the BLE Mesh network.

[0058] Furthermore, the communication module 14 can send the compressed second audio signal to the connected audio playback module so that the audio playback device (such as Figure 1 The audio playback device A21, the audio playback device B22) plays the compressed second audio signal or plays the second audio signal.

[0059] In an embodiment of the present application, the control system 1 may further include an interaction module 15, wherein the interaction module 15 may be a human-computer interaction module. The interaction module 15 may be used to obtain a user's preemption instruction.

[0060] In a specific implementation, each control system may be the receiver of the signal by default. In other words, each control system is in a state of not acquiring the audio signal by default, and only when the interaction module 15 detects the user's preemption instruction, the control system switches to the sender of the signal.

[0061] Taking the control system 1 as an example, if the interaction module 15 obtains the preemption instruction, the interaction module 15 can send the preemption instruction to the control module 12. In response to the received preemption instruction, the control module 12 can send a start signal to the audio input module 11, thereby the audio input module 11 is started, so that the first audio signal can be obtained. Thus, the control system 1 switches to the sender of the signal.

[0062] For example, the interaction module 15 may include a recording button. If the interaction module 15 detects that the first user presses the recording button, it can be determined that the preemption instruction is obtained. Thus, the control module 12 can start the audio input module 11 to collect the first audio signal and send the compressed first audio signal to achieve synchronous audio playback through the BLE Mesh network.

[0063] In the process of the control system 1 being the sender of the signal, users of other control systems may preempt. Specifically, users of other control systems may press the recording button, whereby the communication module 14 of the control system 1 may receive the preemption instruction, and further, the communication module 14 may send the preemption instruction to the control module 12, and in response to receiving the preemption instruction, the control module 12 may send a shutdown signal to the audio input module 11, whereby the audio input module 11 of the control system 1 is shut down to stop acquiring the first audio signal.

[0064] Exemplarily, during the broadcasting of the first user's audio signal, the second user can seize the broadcasting right through the interactive module of the control system 2. Specifically, if the interactive module of the control system 2 detects the second user's preemption instruction, the communication module of the control system 2 can send a preemption instruction to the control system 1, and the audio input module of the control system 2 starts to acquire the second audio signal. The second audio signal can be the audio that the second user wants to play or the voice signal of the second user. Correspondingly, the control system 1 receives the preemption instruction, whereby the audio input module of the control system 1 stops acquiring the first audio signal and receives the compressed second audio signal from the control system 2.

[0065] In a possible implementation, after the control system 1 receives the preemption instruction, the control system 1 may send a confirmation instruction to the control system 2. After the control system 2 receives the confirmation instruction, it starts the audio input module of the control system 42 to obtain the second audio signal. After the control system 1 sends the confirmation instruction, it may stop obtaining the first audio signal.

[0066] Thus, the switching of the sending node is completed to ensure that at the same time in the BLE Mesh network, only one control system can be the sender of the signal, and the other control systems are the receivers of the signal.

[0067] In one embodiment, during the process of the control system 1 sending the compressed first audio signal, the control system 1 may receive multiple preempted instructions in a relatively short period of time, wherein the multiple preempted instructions are sent by different control systems. In this case, the control system 1 may send a confirmation instruction to the sender of the preempted instruction with the highest priority. The priority of the preempted instruction may be determined according to the time when the preempted instruction is received. For example, the later the time when the preempted instruction is received, the higher the priority. For another example, the earlier the time when the preempted instruction is received, the higher the priority.

[0068] Exemplarily, during the process of sending the compressed first audio signal, the control system 1 receives the first preempted instruction and the second preempted instruction, wherein the first preempted instruction is sent by the control system 2, the second preempted instruction is sent by the control system 3, and the time interval between the reception times of the first preempted instruction and the second preempted instruction is less than the preset time threshold. If the control system 1 receives the first preempted instruction earlier than the second preempted instruction, the control system 1 may send a confirmation instruction to the control system 3, whereby the control system 3 becomes the sender of the signal in the BLE Mesh network, and the control system 1 and the control system 3 are the receivers of the signal.

[0069] As described above, the solution provided in the embodiment of the present application provides a voice preemption function. When a node performs voice broadcasting, other nodes can preempt the broadcasting authority through the interaction module and switch the current speaking node, thereby meeting the scene requirements of multiple users interacting.

[0070] Further, in the solution of the embodiment of the present application, the control system 1 may further include a storage module (not shown). Specifically, the user may set the anti-disturbance mode through the interaction module 15. When the anti-disturbance mode is turned on, the control system 1 provides a message function.

[0071] Specifically, if the interaction module 15 detects that the first user turns on the do not disturb mode, in other words, the interaction module 15 obtains the do not disturb setting instruction of the first user, then the control module 12 can identify the second audio signal, and if the second audio signal is the voice of the authorized user, the second audio signal can be written into the storage module so that the second audio signal can be played after exiting the do not disturb mode. Among them, the authorized user can be pre-set by the first user. For example, the first user can set the authorized user in the application of the terminal device. If the second audio signal is the voice of an unauthorized user, for example, the second audio signal is music, the second audio signal can be discarded. Among them, discarding can refer to deletion.

[0072] Further, if the interaction module 15 detects that the first user exits the anti-disturbance mode, the control module 12 may read the stored compressed second audio signal from the storage module, and send the compressed second audio signal to the audio playback device for playback.

[0073] From the above, in the solution of the embodiment of the present application, audio transmission and intelligent control of the device can be integrated into the same control system. Users can realize the functions of voice broadcasting, music playback and smart device control through the system, which can provide users with a comfortable and intelligent life experience.

[0074] The solution provided in the embodiment of the present application can be applied to multiple fields such as smart home, hotel management, conference activities, classroom education, etc.

[0075] One of the application scenarios of the embodiments of the present application may be a home scenario.

[0076] Specifically, the user can perform initial configuration of the control system 1 through the application on the user terminal. Specifically, the user can add each controlled device and audio playback device in the home to the BLE Mesh network to establish a connection with the control system. The user can also assign functions and set parameters for each device.

[0077] Furthermore, the user can issue a voice command or a control command through an application configured on the user terminal to control various controlled devices in the home. For example, the controlled devices are various lamps in the home, so that the user can uniformly control the lights in the home.

[0078] In one example, a user can select a lighting mode through an application to control all lamps in the home to emit light in accordance with the selected lighting mode. Different lighting modes have different lighting effects. For example, the lighting mode can be "dinner mode", "movie mode", "party mode", etc. The user can also broadcast audio signals to the audio playback devices in the home through the control system to achieve whole-house broadcasting of music or voice.

[0079] In one example, at a family gathering, a user can broadcast voice through the microphone of any audio playback device to achieve synchronous playback on all devices.

[0080] One of the application scenarios of the embodiment of the present application may be a hotel scenario.

[0081] For example, a control system can be set up in each room. The occupants of each room are users associated with the control system in the room. The occupants can control each controlled device in the room by voice, and can also achieve synchronous audio playback on each audio playback device in the room.

[0082] As another example, a control system may be provided for each public area, and users associated with the control system of the public area may be hotel staff, who may use the control system to achieve unified control of lighting and synchronous audio playback in the public area.

[0083] One of the application scenarios of the embodiments of the present application may be a conference scenario. A control system may be provided in the conference venue, and the user associated with the control system may be the conference host. Thus, the conference host can achieve centralized control of lighting and audio in the meeting through the control system.

[0084] In a possible implementation, each participant can configure a control system, and the control systems of each participant can be connected through a BLE Mesh network. Each participant can interact with each other through the control system configured by each participant.

[0085] One of the application scenarios of the embodiments of the present application is an educational scenario. A control system may be provided in an educational place, and the user associated with the control system may be a teacher. Thus, the teacher can realize centralized control of lighting and audio in the classroom through the control system.

[0086] From the above, the embodiment of the present application provides a control system, which realizes audio transmission between low-power devices through the combination of efficient audio compression algorithm and BLE Mesh network, and also realizes the integration of audio transmission and device control functions into the same system, which solves the problem of separation of audio transmission and device control functions in the prior art, improves the flexibility and practicality of the system, and optimizes the user experience. In addition, in the scheme of the embodiment of the present application, the control system supports a wide range of device networking, which solves the problem of limited network coverage in the prior art. Therefore, the control system provided by the embodiment of the present application has strong scalability, can be applied to deployment in various scenarios such as homes and hotels, has a wide coverage area, and has high stability.
