[0056] Embodiment one

[0057] Figure 1 The flow chart of the management method of Bluetooth connection provided by the first embodiment of the present application. As shown in the figure, the method is applied to a terminal device, and the method comprises: Figure 1

[0058] Step 101, if the Bluetooth module in the household appliance device is in a connection state, send a verification request, wherein the verification request comprises verification information, wherein the verification information is used to perform a verification operation;

[0059] In an exemplary embodiment, the Bluetooth module of the terminal device can be started, and a device with Bluetooth communication function is searched. The broadcast message sent by the Bluetooth module in the household appliance device is acquired, wherein the broadcast message is used to notify that the Bluetooth module in the household appliance device has been in a connection state, and the information that the Bluetooth module is in a connection state is obtained according to the broadcast message.

[0060] In an exemplary embodiment, the verification request can be sent to the cloud server through the network, and the cloud server is requested to perform a verification operation, wherein the verification information can be the device identifier or user information of the terminal device; wherein the cloud server is used to uniformly manage the household appliance device. Specifically, the cloud server can be the cloud server of the manufacturer of the household appliance device. ​

[0061] In an example embodiment, the verification request can be sent to the home appliance device, requesting the home appliance device to perform the verification operation. For example, after a specific home appliance device is woken up by a preset voice wake-up instruction, a voice control command can be sent to perform the verification operation, such as a voice control command in the format of "Bluetooth verification, content of user identification".

[0062] For example, the user identification of the terminal device is 13812345678, and a verification request can be sent to the cloud server, which carries the verification information of the user identification. Alternatively, after the home appliance device is woken up, a voice control command is output, and the content is "Bluetooth verification 13812345678".

[0063] Step 102, receiving a verification response corresponding to the verification request, wherein the verification response includes a verification result, wherein the verification result is obtained by performing a verification operation on the verification information;

[0064] Taking the cloud server as an example, the cloud server determines whether the verification information is in the local record of the legal user library. If the information record in the verification information is in the legal user library, the verification result is passed; otherwise, the verification result is different.

[0065] For example, if the legal user library records the user identification of the legal user, and records the user identification 13812345678, it means that the verification information is verified.

[0066] Step 103, when the verification result is passed, a connection with the Bluetooth module is established.

[0067] When the verification result is passed, it means that the terminal device has the permission to establish a connection with the Bluetooth module in the home appliance device, and therefore, a connection request with the Bluetooth module is initiated.

[0068] Based on the above verification operation, the home appliance device can disconnect the Bluetooth connection with the illegal user, and further establish a Bluetooth connection with the legal user.

[0069] Optionally, if the cloud server determines that the verification result is passed, the home appliance device can be notified to disconnect the current Bluetooth connection, so as to facilitate the establishment of a Bluetooth connection with the terminal device having the connection establishment permission; if the home appliance device determines that the verification result is passed, the current Bluetooth connection is disconnected, and the Bluetooth connection with the terminal device is waited.

[0070] The method provided by the embodiment one of the present application, if the Bluetooth module in the household appliance is in a connection state, a verification request is sent, wherein the verification request comprises verification information, a verification response corresponding to the verification request is received, wherein the verification response comprises a verification result, and when the verification result is passed, a connection is established with the Bluetooth module, and in the case of a Bluetooth connected device, the Bluetooth connection right is acquired through the verification operation, so that the Bluetooth connection right is retrieved from an illegal user when the illegal user connects through Bluetooth, the household appliance is disconnected from the Bluetooth connection with the illegal user, a Bluetooth connection with a legal user can be established, and the security of the Bluetooth communication of the household appliance is improved.

[0071] Embodiment two

[0072] Figure 2 The flowchart of the Bluetooth connection management method provided by the embodiment two of the present application. As shown in the figure, the method is applied to a terminal device, and the method comprises the following steps. Figure 2

[0073] Step 201, if the Bluetooth module in the household appliance is in a connection state, a target terminal device connected to the Bluetooth module is acquired.

[0074] In an example embodiment, the Bluetooth module of the terminal device can be started, and a device with Bluetooth communication function is searched. A broadcast message sent by the Bluetooth module in the household appliance is acquired, wherein the broadcast message is used to notify that the Bluetooth module in the household appliance is in a connection state, and the information that the Bluetooth module is in a connection state is obtained according to the broadcast message.

[0075] In an example embodiment, the identification information of the target terminal device can be controlled by the household appliance to output the voice control command, and the identification information of the target terminal device is obtained through the voice playing module or the display module of the household appliance.

[0076] Preferably, the identification information of the target terminal device is carried in the broadcast message sent by the Bluetooth module, so as to obtain the target terminal device connected to the Bluetooth module.

[0077] The target terminal device is acquired from the broadcast message of the Bluetooth module, so that the acquisition of the target terminal device is quickly completed, the acquisition efficiency is improved, and the implementation is simple.

[0078] The identification information of the terminal device obtained above is part of the whole content of the identification information, so as to ensure the privacy of the data.

[0079] Taking the identification information of the terminal device as a mobile phone number as an example, if the number of the user information is 13111111111, the identification information of the target terminal device in the broadcast message can be 131*****111, wherein * represents the hidden information.

[0080] ​Step 202, judging whether the target terminal device is a pre-set legal terminal device or not;

[0081] It can be judged whether the verification information is in the locally recorded legal user library. If the identification information of the target terminal device is in the legal user library, the flow ends; otherwise, step 203 is executed.

[0082] If the obtained target identification information is part of the identification information, only the part of the identification information is compared. Taking the identification information of the target terminal device as 131*****111 for example, it is judged whether the identification of the legal user library including 11 characters has the user identification with the first 3 characters being 131 and the last 3 characters being 111. If yes, it is determined that the target terminal device is a legal terminal device; otherwise, it is determined that the target terminal device is an illegal terminal device.

[0083] By judging whether the target terminal device currently connected to the Bluetooth module in the home appliance device is a legal terminal device or not, the occurrence of misoperation can be reduced, and the accuracy of operation can be improved.

[0084] Step 203, sending a verification request, wherein the verification request includes verification information, wherein the verification information is used to execute a verification operation;

[0085] In an example embodiment, the verification request can be sent to a cloud server through a network, requesting the cloud server to perform a verification operation, wherein the verification information can be a device identification of a terminal device or user information; wherein the cloud server is used to uniformly manage home appliance devices. Specifically, the cloud server can be a cloud server of a manufacturer of the home appliance device.

[0086] In an example embodiment, the verification request can be sent to the home appliance device, requesting the home appliance device to perform a verification operation. For example, after a specific home appliance device is woken up by a pre-set voice wake-up instruction, a voice control command can be sent to execute a verification operation, such as a voice control command in the format of "Bluetooth verification, content of user identification".

[0087] For example, the user identification of a terminal device is 13812345678, a verification request can be sent to a cloud server, and the verification information carried by the verification request is the user identification. Or, after the home appliance device is woken up, a voice control command is output, and the content is "Bluetooth verification 13812345678".

[0088] Step 204, receiving a verification response corresponding to the verification request, wherein the verification response includes a verification result, wherein the verification result is obtained by performing a verification operation on the verification information;

[0089] Taking the cloud server receiving the verification request as an example, the cloud server judges whether the verification information is in the local record of the legal user library. If the information record in the verification information is in the legal user library, the verification result is passed; otherwise, the verification result is not passed.

[0090] For example, if the legal user library records the user identification of the legal user, and records the user identification as 13812345678, it indicates that the verification information is verified.

[0091] Step 205, when the verification result is passed, the connection with the Bluetooth module is established.

[0092] When the verification result is passed, it indicates that the terminal device has the permission to establish the connection with the Bluetooth module in the household appliance, and therefore, the connection request with the Bluetooth module is initiated.

[0093] Based on the above verification operation, the household appliance can disconnect the Bluetooth connection with the illegal user, and further establish the Bluetooth connection with the legal user.

[0094] Optionally, if the cloud server determines that the verification result is passed, the household appliance can be notified to disconnect the current Bluetooth connection, so as to facilitate the establishment of the Bluetooth connection with the terminal device having the connection establishment permission; if the household appliance determines that the verification result is passed, the current Bluetooth connection is disconnected, and the Bluetooth connection with the terminal device is waited.

[0095] The method provided by the second embodiment of the application can be used when the Bluetooth module in the household appliance is in the connection state. The verification request is sent, the verification request includes the verification information, the verification response corresponding to the verification request is received, the verification response includes the verification result, and the connection with the Bluetooth module is established when the verification result is passed. In the case of the Bluetooth connected device, the Bluetooth connection right is acquired through the verification operation, so that the Bluetooth connection right can be recovered from the illegal user when the illegal user connects through the Bluetooth, the household appliance can disconnect the Bluetooth connection with the illegal user, and can establish the Bluetooth connection with the legal user, thereby improving the security of the Bluetooth communication of the household appliance. By judging whether the target terminal device connected with the Bluetooth module in the household appliance is a legal terminal device, the occurrence of the misoperation can be reduced, and the accuracy of the operation can be improved.

[0096] Embodiment three

[0097] Figure 3 The flowchart of the Bluetooth connection management method provided by the third embodiment of the application is shown in FIG. 3. Figure 3 As shown in FIG. 3, the method is applied to the terminal device, and the method includes the following steps.

[0098] Step 301, if the Bluetooth module in the household appliance is in the connection state, the target terminal device connected with the Bluetooth module is acquired.

[0099] In an example embodiment, the Bluetooth module of the terminal device can be started to search for a device with Bluetooth communication function. A broadcast message sent by the Bluetooth module in the household appliance device is acquired, where the broadcast message is used to inform that the Bluetooth module in the household appliance device is in a connection state, and information that the Bluetooth module is in the connection state is obtained according to the broadcast message.

[0100] In an example embodiment, the household appliance device can be controlled to output the identification information of the target terminal device through a voice control command, and the identification information of the target terminal device is obtained through the voice playing module or the display module of the household appliance device.

[0101] Preferably, the identification information of the target terminal device can be carried in the broadcast message sent by the Bluetooth module, so as to obtain the target terminal device connected to the Bluetooth module.

[0102] The target terminal device is acquired from the broadcast message of the Bluetooth module, so that the acquisition of the target terminal device can be quickly completed, the acquisition efficiency is improved, and the implementation is simple.

[0103] The obtained identification information of the terminal device is part of the whole content of the identification information, so as to ensure the privacy of the data.

[0104] Taking the identification information of the terminal device as a mobile phone number as an example, if the number of the user information is 13111111111, the identification information of the target terminal device in the broadcast message can be 131*****111, where * represents the hidden information.

[0105] Step 302, determining whether the target terminal device is a pre-set legal terminal device;

[0106] It can be determined whether the verification information is in the local record of the legal user library, if the identification information of the target terminal device is in the legal user library, the process is ended; otherwise, step 203 is executed.

[0107] If the obtained target identification information is part of the identification information, only the part of the content is compared. Taking the identification information of the target terminal device as 131*****111 as an example, it is determined whether the identification information including 11 characters in the legal user library has a user identification with the first 3 characters being 131 and the last 3 characters being 111, if yes, it is determined that the target terminal device is a legal terminal device; otherwise, it is determined that the target terminal device is an illegal terminal device.

[0108] By determining whether the target terminal device currently connected to the Bluetooth module in the household appliance device is a legal terminal device, the occurrence of misoperation can be reduced, and the accuracy of operation is improved.

[0109] Step 303, sending a trigger request, the trigger request being used to trigger the start of the verification operation;

[0110] Wherein, the receiver of the trigger request is the same as the device performing the verification operation.

[0111] Step 304, receiving a trigger response corresponding to the trigger request, the trigger response carrying a verification mode corresponding to the verification operation;

[0112] Wherein, the verification mode can indicate the content of the verification information required to be provided, such as the identification information of the target terminal device or the unique identifier of the home appliance device.

[0113] Step 305, obtaining the verification information corresponding to the verification mode;

[0114] The unique identifier can be the serial number (SN) of the home appliance device.

[0115] For example, the last n digits of the SN of the home appliance device can be used as the verification information, where n can be any integer between 4 and 8.

[0116] The verification mode is obtained through the trigger request, and the verification request is sent based on the verification mode, which avoids the security risks caused by using the default verification mode and improves the security of the verification operation.

[0117] Step 306, sending a verification request including the verification information;

[0118] In an exemplary embodiment, the verification request can be sent to the cloud server through the network; or, sent to the home appliance device through the voice control command.

[0119] A specific home appliance device can be woken up through a preset voice wake-up instruction, and then the voice control command is sent to execute the verification operation, such as the format of the voice control command being "Bluetooth verification, verification information".

[0120] For example, the last 3 digits of the SN of the home appliance device are used as the verification information, and the verification information is 123, the verification request can be sent to the cloud server, and the verification information carried by the verification request is 123. Or, after the home appliance device is woken up, the voice control command is output, and the content is "Bluetooth verification 123".

[0121] Step 307, receiving a verification response corresponding to the verification request, wherein the verification response includes a verification result, and the verification result is obtained by performing the verification operation on the verification information;

[0122] Taking the cloud server receiving the verification request as an example, the cloud server judges whether the verification information is in the local record of the legal user library. If the information record in the verification information is in the legal user library, the verification result is passed; otherwise, the verification result is not passed.

[0123] For example, if the legal user library records the user identification of the legal user, and records the user identification as 13812345678, it indicates that the verification information is verified.

[0124] Step 308, when the verification result is passed, the connection with the Bluetooth module is established.

[0125] When the verification result is passed, it indicates that the terminal device has the permission to establish the connection with the Bluetooth module in the household appliance, and therefore, the connection request with the Bluetooth module is initiated.

[0126] Based on the above verification operation, the household appliance can disconnect the Bluetooth connection with the illegal user, and further establish the Bluetooth connection with the legal user.

[0127] Optionally, if the cloud server determines that the verification result is passed, the household appliance can be notified to disconnect the current Bluetooth connection, so as to facilitate the establishment of the Bluetooth connection with the terminal device having the connection establishment permission; if the household appliance determines that the verification result is passed, the current Bluetooth connection is disconnected, and the Bluetooth connection with the terminal device is waited.

[0128] The method provided in the third embodiment of the application, if the Bluetooth module in the household appliance is in the connection state, the verification request is sent, wherein the verification request includes verification information, the verification response corresponding to the verification request is received, wherein the verification response includes the verification result, and the connection with the Bluetooth module is established when the verification result is passed. In the case of the Bluetooth connected device, the Bluetooth connection right is acquired through the verification operation, so that the Bluetooth connection right can be recovered from the illegal user when the illegal user connects through the Bluetooth, the household appliance disconnects the Bluetooth connection with the illegal user, and can establish the Bluetooth connection with the legal user, thereby improving the security of the Bluetooth communication of the household appliance. By judging whether the target terminal device currently connected with the Bluetooth module in the household appliance is a legal terminal device, the occurrence of the misoperation can be reduced, and the accuracy of the operation is improved. The verification mode is acquired through the trigger request, and the verification request is sent based on the verification mode, thereby avoiding the security risk caused by adopting the default verification mode, and improving the security of the verification operation.

[0129] Embodiment four

[0130] Figure 4 The flowchart of the method for acquiring the voice data provided in the fourth embodiment of the application. As shown in the figure, Figure 4 the method is applied to an air conditioner, and the method comprises the following steps.

[0131] Step 401, if the Bluetooth module in the home appliance device is in a connection state, obtaining a target terminal device connected to the Bluetooth module;

[0132] In an example embodiment, the Bluetooth module of the terminal device can be started to search for a device with Bluetooth communication function. A broadcast message sent by the Bluetooth module in the home appliance device is obtained, where the broadcast message is used to inform that the Bluetooth module in the home appliance device is in a connection state, and the information that the Bluetooth module is in a connection state is obtained according to the broadcast message.

[0133] In an example embodiment, the identification information of the target terminal device can be controlled to be output by the home appliance device through a voice control command, and the identification information of the target terminal device is obtained through the voice playing module or the display module of the home appliance device.

[0134] Preferably, the identification information of the target terminal device is carried in the broadcast message sent by the Bluetooth module, so as to obtain the target terminal device connected to the Bluetooth module.

[0135] The target terminal device is obtained from the broadcast message of the Bluetooth module, so that the target terminal device can be quickly obtained, the efficiency is improved, and the implementation is simple.

[0136] The obtained identification information of the terminal device is part of the whole content of the identification information, so as to ensure the privacy of the data.

[0137] Taking the identification information of the terminal device as a mobile phone number as an example, if the number of the user information is 13111111111, the identification information of the target terminal device in the broadcast message can be 131*****111, where * represents the hidden information.

[0138] Step 402, judging whether the target terminal device is a pre-set legal terminal device or not;

[0139] It can be judged whether the verification information is in the local record of the legal user library or not, if the identification information of the target terminal device is in the legal user library, the process is ended; otherwise, step 403 is executed.

[0140] If the obtained target identification information is part of the identification information, only the part of the content is compared. Taking the identification information of the target terminal device as 131*****111 as an example, it is judged whether the identification information including 11 characters in the legal user library has a user identification with the first 3 characters being 131 and the last 3 characters being 111 or not, if yes, the target terminal device is determined to be a legal terminal device; otherwise, the target terminal device is determined to be an illegal terminal device.

[0141] By judging whether the target terminal device currently connected by the Bluetooth module in the home appliance device is a legal terminal device, the occurrence of misoperation can be reduced, and the accuracy of operation can be improved.

[0142] In step 403, a trigger request for triggering the start of the verification operation is sent by using a broadcast message of the Bluetooth protocol.

[0143] The receiver of the trigger request is the same device as that performing the verification operation.

[0144] In step 404, a trigger response corresponding to the trigger request is received, and the verification mode corresponding to the verification operation is carried in the trigger response.

[0145] The verification mode can indicate the content of the verification information required to be provided, such as the identification information of the target terminal device or the unique identifier of the home appliance device.

[0146] The trigger response is obtained from the broadcast message sent by the Bluetooth module of the home appliance device.

[0147] In step 405, the verification information corresponding to the verification mode is obtained.

[0148] The unique identifier can be the serial number (SN) of the home appliance device.

[0149] For example, the last n digits of the SN of the home appliance device can be used as the verification information, where n can be any integer between 4 and 8.

[0150] The verification mode is obtained by the trigger request, and the verification request is sent based on the verification mode, which avoids the security risks caused by using the default verification mode and improves the security of the verification operation.

[0151] In step 406, a verification request including the verification information is sent by using a broadcast message of the Bluetooth protocol.

[0152] In an exemplary embodiment, the verification request is sent to the home appliance device by using a broadcast message of the Bluetooth protocol.

[0153] For example, the last 4 digits of the SN of the home appliance device can be used as the verification information, and the verification information is 123, and the verification information carried in the verification request is 1234.

[0154] In step 407, a verification response corresponding to the verification request is received, and the verification result is included in the verification response, where the verification result is obtained by performing the verification operation on the verification information.

[0155] The verification response is obtained from the broadcast message sent by the Bluetooth module of the home appliance device.

[0156] Taking the cloud server as an example, the cloud server judges whether the verification information is in the local record of the legal user library. If the information record in the verification information is in the legal user library, the verification result is passed. Otherwise, the verification result is different.

[0157] For example, if the legal user library records the user identification of the legal user, and records the user identification as 13812345678, it means that the verification information is verified.

[0158] Based on the broadcast message sent by the Bluetooth module of the terminal device and the household appliance device, the verification operation is completed, the operation process is simple, and the implementation is convenient.

[0159] Step 408, when the verification result is passed, the connection with the Bluetooth module is established.

[0160] When the verification result is passed, it means that the terminal device has the permission to establish the connection with the Bluetooth module in the household appliance device, so the connection request with the Bluetooth module is initiated.

[0161] Based on the above verification operation, the household appliance device can disconnect the Bluetooth connection with the illegal user, and further establish the Bluetooth connection with the legal user.

[0162] Optionally, if the cloud server determines that the verification result is passed, the household appliance device can be notified to disconnect the current Bluetooth connection, so as to facilitate the establishment of the Bluetooth connection with the terminal device having the connection establishment permission; if the household appliance device determines that the verification result is passed, the current Bluetooth connection is disconnected, and the Bluetooth connection with the terminal device is waited.

[0163] Step 409, the Bluetooth module in the household appliance device is configured with a corresponding device list, wherein the device list records the terminal device allowed to establish the Bluetooth connection with the Bluetooth module.

[0164] By configuring the device list, the Bluetooth module in the household appliance device can be prevented from establishing the connection with the illegal terminal device, and the security of the Bluetooth connection of the household appliance device is improved.

[0165] The method provided by the fourth embodiment of the present application can be used in the home appliance. If the Bluetooth module in the home appliance is in a connection state, a verification request is sent, wherein the verification request comprises verification information. A verification response corresponding to the verification request is received, wherein the verification response comprises a verification result. If the verification result is passed, a connection with the Bluetooth module is established. In the case of a Bluetooth connected device, the Bluetooth connection right is obtained through a verification operation, so that the Bluetooth connection right can be retrieved from an illegal user when the illegal user connects through Bluetooth, the Bluetooth connection of the home appliance with the illegal user is disconnected, the Bluetooth connection with a legal user can be established, and the security of Bluetooth communication of the home appliance is improved. By judging whether the target terminal device currently connected with the Bluetooth module in the home appliance is a legal terminal device, the occurrence of a misoperation can be reduced, and the accuracy of the operation is improved. The verification mode is obtained through a trigger request, and the verification request is sent based on the verification mode, so that the security risk caused by the use of a default verification mode is avoided, and the security of the verification operation is improved. The verification operation is completed based on the broadcast messages sent by the Bluetooth modules of the terminal device and the home appliance, the operation process is simple, and the implementation is convenient. By configuring the device list, the Bluetooth module in the home appliance can be prevented from establishing a connection with an illegal terminal device, and the security of the Bluetooth connection of the home appliance is improved.
