In addition, a remote data transmission system and a receiving controller are arranged in the microphone. Therefore, when remote conversation is carried out, the microphone does not need to be in limited connection with a receiving controller of hardware and a remote data transmission system installed in hardware setting, wherein the remote data transmission system is used for carrying out information interaction with remote data transmission systems of other places, and the receiving controller is used for carrying out data processing on data collected by the microphone, so that the problem that in the prior art, hardware equipment needing to be connected in the remote conversation is too many, and the connection process is complicated and labor is consumed can be effectively solved.
It should be noted that the remote session includes a teleconference, a remote multi-person session, a remote performance, and any activity that requires participation of multiple meeting places.
And 102, the microphone receives a working mode configured by the user terminal according to a preset mode configuration rule.
In this embodiment, in order to enable all the participants in the current conference room to hear the conversation content, different operation modes may be set for at least one microphone, where the operation modes include a master device operation mode and a slave device operation mode. The user terminal can set a working mode for at least one microphone according to a preset mode configuration rule, and accordingly the microphone can receive the working mode sent by the user terminal, so that the user terminal can subsequently work according to the working mode. For example, in the process of connecting the microphones to the user terminal, the user terminal may use the first connected microphone as a master device microphone, and accordingly, the working mode corresponding to the master device microphone is the master device working mode, and use another microphone that is subsequently connected as a slave device, and accordingly, the working mode corresponding to the slave device is the slave device working mode. As an implementation manner, different operation modes may be set for the microphones according to the positions of the microphones, for example, a microphone close to the conversation speaker may be used as a master microphone, and the other microphones may be used as slave microphones. The setting of the microphone operation mode may be performed according to practical applications, and the present invention is not limited herein.
And 103, receiving a session opening instruction by the microphone, and executing data acquisition operation corresponding to the working model according to the session opening instruction and the working mode.

In the data acquisition method provided by this embodiment, a wireless communication connection is established with a user terminal through microphones, the number of the microphones is at least one, and a remote data transmission system and a receiving controller are installed in the microphones; the microphone receives a working mode configured by the user terminal according to a preset mode configuration rule; and the microphone receives a conversation opening instruction, and executes data acquisition operation corresponding to the working model according to the conversation opening instruction and the working mode. Because the microphone is internally provided with the remote data transmission system and the receiving controller, the problem that in the prior art, the connecting process is complicated and labor is consumed due to the fact that too many hardware devices need to be connected in the remote session can be effectively solved.
Fig. 3 is a schematic flow chart of a data acquisition method according to a second embodiment of the present invention, where on the basis of any of the above embodiments, as shown in fig. 3, the method includes:
and 208, the microphone receives a conversation opening instruction, and executes data acquisition operation corresponding to the working model according to the conversation opening instruction and the working mode.
In this embodiment, to implement a remote session, first, the microphone needs to be communicatively connected to the user terminal. As an implementation manner, if the current microphone and the user terminal are in the same network environment, the microphone may receive a service information acquisition instruction sent by the user terminal, and feed back service information of the microphone to the user terminal according to the service information acquisition instruction, where the service information includes, but is not limited to, a service type, an IP address, and a service port. In practical application, after a User terminal joins into a local area network, a multicast DNS (abbreviated mDNS) service is started, a User Datagram Protocol (UDP) is used to request services from all hosts in the local area network, and other microphones in the local area network return their service information (service type, IP address, service port) to the User terminal after receiving the service information; when a microphone is added into the existing Wi-Fi network, the service information (service type, IP address and service port) of the microphone is broadcasted to all devices (including the microphone and the user terminal) in the local area network. Thus, the user terminal can find the service information of the microphone through the mDNS service as long as the user terminal is under the same Wi-Fi network, and the user terminal is added after the user terminal or the microphone. The microphone provides a Transmission Control Protocol (TCP) service, and the mDNS service type is _ TCP. And when the user terminal finds the service information of the microphone, connecting to the microphone through the tcp client. Thus, the user terminal and the microphone can communicate with each other via tcp. As another implementation manner, if the microphone and the user terminal are not currently connected to the same network environment, the microphone first needs to perform bluetooth connection with the user terminal and receive network configuration information sent by the user terminal through bluetooth. Bluetooth is a radio technology that supports short-range communication (typically within 10 m) of devices, enabling wireless information exchange between a number of devices including mobile phones, tablets, wireless headsets, laptops, related peripherals, etc. With the bluetooth technology, communication between mobile communication terminal devices can be effectively simplified. Specifically, the microphone receives network configuration information sent by the user terminal through bluetooth, the microphone is connected to the same network environment with the user terminal according to the network configuration information sent by the user terminal through bluetooth, when the microphone and the user terminal are connected to the same network environment, a service information acquisition instruction sent by the microphone to a local area network to which the microphone is currently connected is acquired, and self service information is sent to the user terminal according to the service information instruction, so that at least one microphone is in wireless communication connection with the user terminal. It should be noted that the two embodiments described above can be implemented separately or in combination, and the present invention is not limited herein.
In the data acquisition method provided by this embodiment, the microphone receives a service information acquisition instruction sent by the user terminal to the lan to which the microphone is currently connected, and sends service information of the microphone to the user terminal according to the service information instruction, so that the at least one microphone is in wireless communication with the user terminal, the microphone is in communication connection with the user terminal through bluetooth, and receives network configuration information sent by the user terminal through bluetooth, the microphone is connected to the same network environment as the user terminal according to the network configuration information, acquires a service information acquisition instruction sent by the microphone to the lan to which the microphone is currently connected, and sends service information of the microphone to the user terminal according to the service information instruction, so that the at least one microphone is in wireless communication with the user terminal, therefore, a foundation is provided for subsequent data acquisition on the basis of reducing the complexity of equipment connection.
Further, on the basis of any of the above embodiments, the working modes include a master device working mode and a slave device working mode, and one of the at least one microphone is the master device working mode, and the rest microphones are the slave device working modes; the method further comprises the following steps:

if the microphone is in the slave equipment working mode, connecting a wireless hotspot started by the master equipment working mode microphone, and initializing a data acquisition module;
and the microphone receives a conversation opening instruction, and executes data acquisition operation corresponding to the working model according to the conversation opening instruction and the working mode.
In this embodiment, after the microphones establish a wireless communication connection with the user terminal and receive the operation mode sent by the user terminal, a communication connection needs to be established between the microphones. Specifically, if the microphone is in the master device operating mode, the microphone starts the wireless hotspot of the microphone, so that the microphones in the other slave device modes are connected to the wireless hotspot. Correspondingly, if the microphone is in the slave device working mode, the microphone can be directly connected to the wireless hotspot of the microphone in the master device working mode, and the data acquisition module is initialized, so that data acquisition can be carried out subsequently.
In the data acquisition method provided by this embodiment, if the microphone is in the master device working mode, the wireless hotspot of the microphone is turned on, so that the microphones of the other slave device working models are connected, the remote data transmission system is initialized, and the remote data transmission system logs in to the cloud server; if the microphones are in the slave equipment working mode, the wireless hotspots started by the microphones in the master equipment working mode are connected, and the data acquisition module is initialized, so that wireless connection among the microphones can be realized, and a foundation is provided for subsequent data acquisition.

Fig. 4 is a schematic flow chart of a data acquisition method according to a third embodiment of the present invention, where on the basis of any of the above embodiments, as shown in fig. 4, the method includes:
301, establishing wireless communication connection between microphones and a user terminal, wherein the number of the microphones is at least one, and a remote data transmission system and a receiving controller are installed in the microphones;
and 304, if the microphone is in the slave equipment working mode, performing data acquisition operation according to an acquisition data instruction sent by the microphone in the master equipment working mode, and sending acquired data to the microphone in the master equipment working mode.
In this embodiment, after the microphone establishes a wireless communication connection with the user terminal and receives a working mode sent by the user terminal, a data acquisition operation needs to be performed, where operations performed by the microphone in different working modes are different. Specifically, if the microphone is in the master device operating mode, a data acquisition instruction may be sent to the microphone in each slave device operating mode according to the connected wireless hotspot, so that the microphone in each slave device operating mode performs data acquisition operation according to the data acquisition instruction, and sends acquired data to the microphone in the master device operating mode. In addition, the microphone of the master device operation mode needs to establish a communication connection with the remote session server in order to transmit the session data collected by the microphone of the current slave device operation mode to the remote session server.
In the data acquisition method provided by this embodiment, the microphone receives a session start instruction, if the microphone is in the master device operating mode, a data acquisition instruction is sent to the microphone in each slave device operating mode, and a communication connection is established with the remote session server to implement data interaction, and if the microphone is in the slave device operating mode, data acquisition is performed according to the data acquisition instruction sent by the microphone in the master device operating mode, and acquired data is sent to the microphone in the master device operating mode, so that acquisition of session data can be implemented on the basis of reducing the complexity of device connection.
Fig. 5 is a schematic flow chart of a data acquisition method according to a fourth embodiment of the present invention, where on the basis of any of the foregoing embodiments, as shown in fig. 5, the method includes:
and step 408, performing echo removing operation on the data to be transmitted to obtain effective information.
In this embodiment, after receiving the session start instruction, the microphone may perform data acquisition, specifically, if the microphone is in the slave device operating mode, the microphone may acquire session data through a data acquisition module arranged in the microphone, and may further perform data processing on the data, where the data processing includes, but is not limited to, noise suppression and automatic gain control, to obtain data to be transmitted. Further, in order to ensure data security, data to be transmitted may be encoded, and the encoded data to be transmitted is sent to the microphone in the working mode of the host device. Correspondingly, the microphone in the master device mode may receive the encoded data to be transmitted, and decode the encoded data to be transmitted according to an agreed rule to obtain the data to be transmitted. In addition, in order to further improve the data quality, it is necessary to perform an echo removing operation on the data to be transmitted to obtain effective information. Specifically, the host device receives compressed audio data from the network and puts the compressed audio data into a buffer (JitterBuffer), which is responsible for sorting and jitter control of received data packets, and then sends the data packets to a decoder for decoding into an original audio data format. Since the sound collected by the microphone is the superposition of the useful sound and the sound played by the speaker, the sound (echo) played by the speaker needs to be removed. However, the sound from each microphone may vary in time for a variety of reasons (distance from speaker, network jitter, etc.), so that each path must be separately de-echoed. In particular, an adaptive echo-removing algorithm can be adopted to ensure that each channel only contains useful voice information.
In the data acquisition method provided by this embodiment, if the microphone is in the slave device operating mode, data acquisition is performed through a preset data acquisition module, noise suppression and automatic gain control are performed on the acquired data, data to be transmitted is obtained, the data to be transmitted is encoded, the encoded data to be transmitted is sent to the microphone in the master device operating mode, accordingly, if the microphone is in the master device operating mode, the encoded data to be transmitted is received, the encoded data to be transmitted is decoded, the data to be transmitted is obtained, echo removal operation is performed on the data to be transmitted, and effective information is obtained. Therefore, the quality of the collected data and the safety in the data transmission process can be improved on the basis of reducing the complexity of equipment connection.
Further, on the basis of any of the above embodiments, the method further includes:
the method comprises the following steps that wireless communication connection is established between microphones and a user terminal, the number of the microphones is at least one, and a remote data transmission system and a receiving controller are installed in the microphones;
the microphone receives a working mode configured by the user terminal according to a preset mode configuration rule;
the microphone receives a conversation opening instruction, and executes data acquisition operation corresponding to the working model according to the conversation opening instruction and the working mode;
if the microphone is in a slave equipment working mode, data acquisition is carried out through a preset data acquisition module;
carrying out noise suppression and automatic gain control on the acquired data to obtain data to be transmitted;
encoding the data to be transmitted, and sending the encoded data to be transmitted to a microphone of the working mode of the main equipment;
correspondingly, if the microphone is in a main equipment working mode, receiving the coded data to be transmitted, and decoding the coded data to be transmitted to obtain the data to be transmitted;
performing echo removing operation on the data to be transmitted to obtain effective information;
and carrying out sound mixing operation on the effective information corresponding to the microphone of each slave device working mode.
In this embodiment, since the number of the microphones is at least one, the microphone in the master device operation mode may receive the session data sent by the microphones in the slave device operation modes at the same time, and thus, a mixing operation needs to be performed on multiple paths of session data. Any algorithm capable of implementing the mixing operation may be used to implement the mixing of the multiple paths of effective data, for example, an arithmetic mean method may be used to perform the mixing operation. Specifically, for each path of valid data, two paths of the largest acquired frame energy may be selected as a mixing source to mix sound according to a preset mixing period, where the mixing period may be set by a user, or may be default by a system, and for example, the mixing period may be 10 ms. Further, it is necessary to process the path with the changed mixing state: the previous period does not participate in sound mixing, the path participating in sound mixing at this time is subjected to fade-in (RampIn) operation, the previous period participates in sound mixing, and the path not selected as a sound mixing source in the current period is subjected to fade-out (RampOut) operation. It can be understood that, in order to improve the quality of the mixed data, a high-pass filtering operation may be performed again at a sampling point 10ms after the mixing is finished, so as to reduce the reverberation effect caused by the mixing.
According to the data acquisition method provided by the embodiment, the mixing operation is performed on the effective information corresponding to the microphones of the working modes of the slave devices, so that the data fusion can be effectively realized on the basis of reducing the complexity of the device connection.
Further, on the basis of any of the above embodiments, the method comprises:
the method comprises the following steps that wireless communication connection is established between microphones and a user terminal, the number of the microphones is at least one, and a remote data transmission system and a receiving controller are installed in the microphones;
the microphone receives a working mode configured by the user terminal according to a preset mode configuration rule;
the microphone receives a conversation opening instruction, and executes data acquisition operation corresponding to the working model according to the conversation opening instruction and the working mode;
if the microphone is in a slave equipment working mode, data acquisition is carried out through a preset data acquisition module;
carrying out noise suppression and automatic gain control on the acquired data to obtain data to be transmitted;
encoding the data to be transmitted, and sending the encoded data to be transmitted to a microphone of the working mode of the main equipment;
correspondingly, if the microphone is in a main equipment working mode, receiving the coded data to be transmitted, and decoding the coded data to be transmitted to obtain the data to be transmitted;
performing echo removing operation on the data to be transmitted to obtain effective information;
carrying out sound mixing operation on effective information corresponding to the microphones of the working modes of the slave devices;
and coding the effective information after sound mixing, and sending the coded effective information to the remote data transmission system so as to enable other conference rooms accessed to the remote data transmission system to participate in the current conversation.
In this embodiment, the microphone is provided with a remote data transmission system, and if there are a plurality of participating locations, the currently acquired effective information can be sent to the remote data transmission system in real time, so as to implement session sharing. Specifically, in order to ensure the security of data transmission, the mixed effective information may be encoded, and the encoded effective information may be sent to the remote data transmission system, so that other conference rooms accessing the remote data transmission system participate in the current session.
According to the data acquisition method provided by the embodiment, the effective information after sound mixing is coded, and the coded effective information is sent to the remote data transmission system, so that other conference rooms accessed to the remote data transmission system participate in the current session, and session sharing can be realized on the basis of reducing the complexity of equipment connection.
Further, on the basis of any one of the above embodiments, the microphone is further provided with a speaker, and the method further includes:
acquiring the coded effective information from the remote data transmission system;
and decoding the effective information, and playing the effective information through the loudspeaker.
In this embodiment, if the current microphone is a microphone in a teleconference room, the remote data transmission system may be accessed, the encoded effective information may be obtained from the remote data transmission system, the encoded effective information may be decoded according to a preset decoding rule, and the effective information may be played through a speaker provided in the remote data transmission system, so as to implement session sharing.
In the data acquisition method provided by this embodiment, the coded effective information is acquired from the remote data transmission system; and decoding the effective information, and playing the effective information through the loudspeaker. Therefore, session sharing can be realized on the basis of reducing the complexity of equipment connection.
