[0025] Currently, most recording devices on the market only support single-channel Bluetooth transmission or simple USB direct reading, and cannot simultaneously adapt to scenarios such as wireless transmission from mobile terminals, wired transmission from mobile terminals, and reading from computer devices. In other words, recording devices generally suffer from the problem of single transmission method and unreasonable communication architecture, resulting in low data transmission efficiency.

[0026] This application provides a data transmission method, recording device, and recording system for improving the data transmission efficiency of the recording device.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic block diagram of a recording device provided in an embodiment of this application. The recording device 100 includes a control unit 110, and a first communication unit 120, a second communication unit 130, a data interface 140, and a storage unit 150 connected to the control unit 110.

[0028] In this embodiment, the recording device 100 can be a portable wearable recording device, such as a recording clip, etc., which is not limited here. The control unit 110 can be the controller or processor of the recording device 100, the first communication unit 120 can be a Bluetooth communication unit, the second communication unit 130 can be a WIFI communication unit (WIFI, Wireless Fidelity, wireless network communication technology), the data interface 140 can be a Type C interface or a USB interface (USB, Universal Serial Bus, etc.), and the storage unit 150 includes an encrypted non-volatile storage unit 150, etc., which is not limited here.

[0029] Furthermore, the recording device 100 includes a pickup unit. When the recording device 100 enters the recording state, the control unit 110 controls the pickup unit to start, converts the sound signal into audio data through the pickup unit, and stores the audio data in the storage unit 150. The recording device 100 can communicate with the terminal device through at least one of the first communication unit 120, the second communication unit 130, and the data interface 140. When entering the data transmission state, the audio data can be transmitted to the terminal device through at least one of the communication connection methods of the first communication unit 120, the second communication unit 130, and the data interface 140.

[0030] Next, combined Figure 1 This application introduces a data transmission method for a recording device according to an embodiment. Please refer to [link / reference]. Figure 2 Specifically, it includes the following steps: Step S21: In response to establishing an instruction transmission channel with the terminal device through the first communication unit and receiving a data upload instruction through the instruction transmission channel, control the second communication unit to establish a data transmission channel with the terminal device.

[0031] In this embodiment, the user can operate the recording device to establish a wireless communication connection with the terminal device and transmit audio data to the terminal device via wireless communication. During the establishment of the wireless communication connection, the control unit of the recording device can first establish a command transmission channel with the terminal device through a first communication unit. This command transmission channel is used for various command interactions between the two ends. For example, when the first communication unit is a Bluetooth unit, the control unit of the recording device controls the Bluetooth unit to establish a Bluetooth communication connection with the terminal device, receiving commands from the terminal device or transmitting commands to the terminal device through the Bluetooth communication connection.

[0032] After receiving a data upload command from the terminal device via the command transmission channel, the control unit further establishes a data transmission channel with the terminal device through the second communication unit. This data transmission channel is used for the transmission of various large amounts of data between the two ends. For example, when the second communication unit is a Wi-Fi unit, the control unit of the recording device controls the Wi-Fi unit to connect to the terminal device's Wi-Fi hotspot to establish a Wi-Fi communication connection. Audio data is then transmitted to the terminal device or updated data is received from the terminal device via this Wi-Fi connection. In some embodiments, the data transmission rate of the second communication unit is greater than that of the first communication unit.

[0033] Step S22: Transmit the audio data in the storage unit to the terminal device through the data transmission channel.

[0034] In this embodiment of the application, after determining that a data transmission channel has been established with the terminal device through the second communication unit, the control unit of the recording device transmits the audio data in the storage unit to the terminal device through the data transmission channel.

[0035] In some embodiments, after the recording device converts the sound signal into audio data through the pickup unit in recording mode, the control unit can encrypt the audio data before storing it in the storage unit. In data transmission mode, the control unit can also decrypt the audio data before transmitting it to the terminal device through the data transmission channel.

[0036] Step S23: In response to establishing a communication connection with the terminal device through the data interface and receiving the verification information, compare the verification information with the pre-stored information.

[0037] In this embodiment, the user can also connect the recording device to the terminal device via a wired communication connection to transmit audio data to the terminal device. After the user connects the recording device's data interface to the terminal device, the control unit establishes a communication connection between the data interface and the terminal device accordingly. Upon receiving verification information, the control unit compares the verification information with pre-stored information. The verification information is used to verify the security of the current connection operation.

[0038] In some embodiments, the verification information can be transmitted from the terminal device to the control unit via a data interface, or it can be generated by the user operating the recording device; this is not limited here.

[0039] Step S24: When it is determined that the verification information is consistent with the pre-stored information, the audio data in the storage unit is transmitted to the terminal device through the data interface, or the terminal device is authorized to read the audio data in the storage unit through the data interface.

[0040] In this embodiment, when the control unit determines that the verification information matches the pre-stored information, it determines that the current connection operation is secure. It can then transmit the audio data in the storage unit to the terminal device via the data interface, or allow the terminal device to read the audio data in the storage unit via the data interface. For example, when the terminal device is a mobile phone, the control unit can transmit the audio data in the storage unit to the mobile phone via the data interface; when the terminal device is a computer, the control unit can authorize the computer to read the audio data in the storage unit via the data interface.

[0041] It is understood that the data transmission method of this application embodiment, by setting a first communication unit, a second communication unit, and a data interface on the recording device, establishes an instruction transmission channel with the terminal device through the first communication unit and a data transmission channel with the terminal device through the second communication unit when transmitting data wirelessly. Instruction interaction is performed through the instruction transmission channel, and audio data is transmitted through the data transmission channel. When transmitting data wiredly, a communication connection is established with the terminal device through the data interface. After verification, the audio output is transmitted to the terminal device through the data interface, or the terminal device is authorized to access the audio data through the data interface. Thus, the recording device can cope with various scenarios through various data transmission methods, thereby improving the data transmission efficiency of the recording device.

[0042] Please refer to Figure 3 , Figure 3 This is a schematic flowchart illustrating the data transmission method of the second recording device provided in this application embodiment. Figure 2 Compared to the data transmission method shown, Figure 3 The data transmission method shown also includes the following steps: Step S25: In response to the recording device entering the charging state, establish a network connection with the historical routing device through the second communication unit.

[0043] In this embodiment, after the recording device enters the charging state, the control unit can also establish a network connection with the historical routing device through the second communication unit. The data interface of the recording device can be connected to the charging adapter to receive electrical energy to charge the recording device; that is, the control unit determines that the recording device has entered the charging state after the data interface is connected to the charging adapter.

[0044] The second communication unit is a WIFI unit. The control unit stores the routing key corresponding to the historical routing device. After entering the charging state, the control unit controls the WIFI unit to establish a network connection with the historical routing device through the routing key.

[0045] Step S26: After successfully establishing a network connection with the historical routing device, the audio data in the storage unit is transmitted to the cloud server through the historical routing device.

[0046] In this embodiment, after the recording device successfully establishes a network connection with the historical routing device while charging, the control unit can transmit the audio data in the storage unit to the cloud server through the historical routing device. The unique device code of the recording device is pre-bound to the cloud account on the cloud server. After the audio data is transmitted to the cloud server, it can be stored in the storage space corresponding to the cloud account to ensure the security of the audio data storage.

[0047] In some embodiments, the first communication unit is a Bluetooth communication unit, and the second communication unit is a Wi-Fi communication unit. Please refer to... Figure 4 , Figure 4 A schematic diagram of a data transmission channel for transmitting audio data, provided in this application embodiment, specifically includes the following steps: Step S41: After establishing a command transmission channel through the Bluetooth communication unit, receive the hotspot key of the terminal device through the command transmission channel.

[0048] In this embodiment, the control unit establishes a command transmission channel via the Bluetooth communication unit and further uses the command transmission channel to receive the hotspot key of the terminal device. In some embodiments, the control unit may also store the hotspot key of the terminal device, and can directly use the hotspot key to connect to the terminal device's Wi-Fi hotspot the next time a data transmission channel is established with the terminal device.

[0049] Step S42: Establish a data transmission channel between the WIFI communication unit and the terminal device according to the hotspot key.

[0050] In this embodiment, after obtaining the hotspot key of the terminal device, the control unit controls the WIFI communication unit to establish a data transmission channel with the terminal device through the hotspot key.

[0051] Step S43: Select the target audio data from the storage unit according to the data upload instruction.

[0052] Step S44: Transmit the target audio data to the terminal device through the data transmission channel.

[0053] In this embodiment, after the recording device establishes a data transmission channel with the terminal device through the WIFI communication unit, the control unit further selects the corresponding target audio data from the storage unit according to the data upload instruction, and transmits the target audio data to the terminal device through the data transmission channel.

[0054] In some embodiments, such as Figure 5As shown, the recording device 100 also includes a biometric verification unit 160. Alternatively, a terminal device may also include a biometric verification unit 160. The biometric verification unit 160 is used to acquire verification information and transmit it to the control unit. For example, when the recording device 100 includes a biometric verification unit 160, the verification information can be directly transmitted to the control unit. If the terminal device uses its own biometric verification unit 160, after acquiring the verification information through the biometric verification unit 160, the terminal device can transmit the verification information to the recording device 100 via a command transmission channel or a data interface.

[0055] Please refer to Figure 6 , Figure 6 A flowchart illustrating a verification terminal device provided in this application embodiment specifically includes the following steps: Step S61: After establishing a communication connection with the terminal device through the data interface, start the biometric verification unit and obtain verification information through the biometric verification unit.

[0056] Step S62: Compare the verification information with the pre-stored information.

[0057] In this embodiment, after establishing a communication connection with the terminal device via a data interface, the control unit can activate the biometric verification unit via an instruction. For example, if the biometric verification unit is installed on a recording device, the control unit can directly control the activation of the biometric verification unit on the recording device. If the biometric verification unit is used on a terminal device, the control unit can transmit an instruction to the terminal device via the data interface to notify the terminal device to activate the biometric verification unit. After activating the biometric verification unit, verification information is obtained through the biometric verification unit. After obtaining the verification information, the control unit compares the verification information with pre-stored information.

[0058] The biometric verification unit is a fingerprint detection unit, and the verification information is fingerprint information. That is, the recording device can be equipped with a fingerprint detection unit, or the fingerprint detection unit of the terminal device can be used. The biometric verification unit is also an image acquisition unit, and the verification information is facial information. That is, the recording device can be equipped with an image acquisition unit, or the image acquisition unit of the terminal device can be used.

[0059] In some embodiments, the terminal device is a mobile terminal or a computer device. Please refer to... Figure 7 , Figure 7 A flowchart illustrating the process of transmitting or reading audio data via a data interface, as provided in this application embodiment, specifically includes the following steps: Step S71: When the device is identified as a mobile terminal, the audio data in the storage unit is transmitted to the terminal device through the data interface.

[0060] In this embodiment of the application, the mobile terminal includes mobile phones and tablet computers, etc. When the control unit determines that the verification information is consistent with the pre-stored information and determines that the data interface is connected to the mobile terminal, it transmits the audio data in the storage unit to the terminal device through the data interface.

[0061] Step S72: When the device is identified as a computer device, authorize the computer device to read audio data from the storage unit through the data interface.

[0062] In this embodiment, when the control unit determines that the verification information is consistent with the pre-stored information and determines that the data interface is connected to a computer device, it authorizes and allows the computer device to read the audio data in the storage unit through the data interface.

[0064] The aforementioned data transmission method further includes: converting the sound signal into initial audio data via the pickup unit 170. The control unit encrypts the initial audio data into audio data according to a preset key and stores it in the storage unit. When transmitting or retrieving audio data, the control unit decrypts the audio data according to the preset key.
