[0004] However, such smart home voice control products often require users to log in to the cloud and interact with relevant commands in the cloud to achieve voice control of the home. This creates an embarrassing situation, that is, it is impossible to control home devices by voice when the network is disconnected. Therefore, users cannot use such voice control products in places without network or when the network is temporarily disconnected.

[0005] In addition, the cloud login operation of smart home products may also cause another serious problem, that is, the cloud login operation means that the user's privacy information (for example, name, mobile phone number, WeChat account, etc.) will have to be leaked to the cloud, causing potential information leakage, which users who care more about private information are not happy about. Summary of the invention

[0006] The present invention provides an offline voice system for smart home, which effectively solves the problems existing in the prior art mentioned above.

[0019] The technical solutions of various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides an offline voice system for smart home. In short, the system can use low-power Bluetooth Mesh to form a network to achieve communication and data transmission between multiple devices. In the Mesh network, each device can act as a node to transfer data from one node to another. Figure 1 An exemplary schematic diagram of the intelligent interconnection of various home appliances in the offline voice system of the present invention is shown in FIG.

[0021] like Figure 1As shown in the figure, users can use Bluetooth Mesh to perform offline voice control on devices such as speakers, vacuum cleaners, air conditioners, and lights indoors.

[0022] Figure 2 Then Figure 1 The exemplary schematic diagram in FIG. Figure 2 As shown, indoor devices A, B, C, D, E, F, L, M, X, Y, and Z are networked through Bluetooth Mesh. Therefore, users can control many devices in the Bluetooth Mesh network through voice without any cloud interaction. Users do not need to log in to the cloud and upload personal data to the cloud for control operations as in the prior art.

[0023] The specific operation architecture of the offline voice system for smart home according to the present invention will be described in detail below. Figure 3 The following is a flowchart showing the operation of the offline voice system for smart home according to the present invention.

[0024] The offline voice system of the present invention uses the offline voice control center as a hub to perform network configuration operations on one or more home appliances through Bluetooth connection. The so-called offline voice control center can be a single physical device or an auxiliary device integrated on a terminal device (for example, a mobile phone, a tablet computer, etc.).

[0025] Each home appliance sends a networking instruction corresponding to the operation action to the offline voice control center through its own operation action, thereby making the home appliance enter the networking mode. When all home appliances enter the networking mode, all home appliances will form a home local area network with the offline voice control center as the core.

[0026] For example, if you want to network the living room lamp, you can carry out the relevant networking operations for the living room lamp and quickly turn on and off the wall switch corresponding to the lamp for a specific number of times, such as 3 or 6 times. This will trigger the networking instruction for the living room lamp. The networking instruction is sent to the offline voice control center via Bluetooth connection, thereby adding the living room lamp to the home LAN.

[0027] For another example, if you want to network the living room air conditioner, you can start the relevant networking operations for the living room air conditioner. Within 3 seconds after turning on the air conditioner, press and hold the networking button on the remote control for 2 seconds, which will trigger the networking command for the living room air conditioner. The networking command is sent to the offline voice control center via Bluetooth connection, thereby adding the living room air conditioner to the home LAN.

[0028] Furthermore, each home appliance is embedded with a coding switch, which contains a device code, which in turn contains a scene code and a number code. The scene code indicates the home scene where the home appliance is located, such as a living room, kitchen, bathroom, etc. The number code indicates the home appliance number in the home scene specified by the scene code.

[0029] For example, the living room chandelier, which is a home appliance, has a scene code pointing to the living room, and the living room contains three lamps: a table lamp (number 001), a chandelier (number 002), and a floor lamp (number 003). The number code of the living room chandelier is 002, which distinguishes the living room chandelier from the living room table lamp and the living room floor lamp.

[0030] When networking, the coding switch of the home appliance is turned on at the same time. Then, when networking is completed, the networking instruction and the device code contained in the coding switch are sent to the offline voice control center together. Thus, in the offline voice control center, the networking instruction and the device code form a one-to-one mapping relationship.

[0031] Once the home appliance is successfully networked, the voice command setting link is entered. In this link, for a specific function of a specific home appliance, the user inputs a set voice to the offline voice control center to form a voice signal, and the voice signal is converted into a digital signal in the offline voice control center, thereby matching the specific function of the specific home appliance and the device code contained in the coding switch of the home appliance. Once the match is successful, a corresponding relationship is established between the specific function, the set voice, the voice signal, the home appliance, and the device code. When the user subsequently wants to enable a specific function of the home appliance, he only needs to shout the same words as the set voice indoors, and the offline voice control center can lock the corresponding home appliance according to the device code and implement the specific function for the home appliance.

[0032] For example, once the living room chandelier is successfully networked, the user can establish a Bluetooth connection between the offline voice control center and the living room chandelier when starting the living room chandelier light-on function in the next voice command setting phase. On this basis, when the user shouts "turn on the light" in the room, the preset voice of "turn on the light" will be converted into a digital signal in the offline voice control center, thereby matching it with the actual "turn on the light" function of the living room chandelier. At the same time, as mentioned above, the device code of the living room chandelier is pre-stored in the offline voice control center. Therefore, the preset voice "turn on the light" forms a matching relationship with the device code of the living room chandelier. Therefore, when the user subsequently wants to turn on the living room light, he only needs to shout "turn on the light" in the living room to match the digital signal with the corresponding light-on function, and the living room chandelier will be turned on.

[0033] This operation allows users to achieve customized control based on the indoor LAN. Different users have different language habits. For example, the user above is accustomed to using "turn on the light" to describe turning on the living room light, but there are other users who are accustomed to using "turn on the light" to express this meaning. Therefore, through the above operation, in the voice command setting link, the customer can also shout "turn on the light" in the living room, thereby matching it with the actual "turn on the light" function of the living room light. Therefore, when the user subsequently wants to turn on the living room light, he only needs to shout "turn on the light" in the living room to match the digital signal with the corresponding light-on function, and the living room light will be turned on.

[0034] At this point, the offline voice system for smart home provided by the present invention has been basically described. The offline voice system for smart home according to the present invention sends a network configuration instruction corresponding to the operation action to the offline voice control center based on the Bluetooth connection, thereby enabling the home appliances to enter the networking mode, and then the home appliances can be voice controlled indoors. Furthermore, the voice control can allow users to realize customized control on the basis of building an indoor local area network. The networking of the entire solution can be realized without any external network connection, and there is no need for users to log in and operate in the cloud, so a smooth connection can be achieved even when the network is disconnected.

[0035] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
