As shown in
In this embodiment, the method for configuring the network for the household appliance includes the following operations:
S1, searching for, by a control terminal, connection information of nearby household appliance, and establishing a connection with the household appliance when the connection information of the household appliance is found.
The connection information includes, for example, the hotspot information of the household appliance for other devices to search for and connect. When the household appliance needs to be networked, the control terminal starts a network configuration program, searches for connection information of nearby household appliance, and establishes a connection with the household appliance based on the searched connection information. In order to ensure that the connected household appliance is a household appliance for which the user needs to configure network, the search result may be displayed to the user for confirmation. If there are multiple pieces of household appliance information searched, the search result may also be displayed to the user for confirmation. After receiving the confirmation response, the control terminal establishes a connection with the household appliance corresponding to the confirmed connection information.
S2, sending the network configuration information corresponding to the household appliance to the household appliance that has established a connection, to make the household appliance perform network configuration according to the network configuration information.
After the connection between the control terminal and the household appliance is established, the control terminal can send the network configuration information corresponding to the household appliance to the household appliance through the established communication link, so that the household appliance can perform network configuration according to the network configuration information. The network configuration information, such as router information for access to the network, secure random numbers, account information of the control terminal, etc., is used for network configuration of household appliances. The household appliance connects to the router according to the network configuration information, and logs into the cloud server to authenticate the household appliance.
S3, authenticating the control terminal after the network configuration is successfully performed, to realize control of the household appliance by the control terminal.
Since operations S1 and S2 are only for network configuration, that is, the household appliance is successfully accessed to the cloud server, and the corresponding relationship between the household appliance and the control terminal is established, but the control terminal is not authenticated. In order to prevent other illegal control terminals from controlling the household appliance, after the network is successfully configured for household appliance, the household appliance is authenticated. Therefore, not only fast and effective network configuration is ensured, but also the control terminal is authenticated, to reliably control the household appliance.
In the implementation of the present disclosure, the control terminal searches for the connection information of the nearby household appliance, to establish a connection with the household appliance and send the network configuration information of the household appliance to the connected household appliance, so that the household appliance can perform fast and effective network configuration according to the network configuration information, and successfully connect to the router. After the network configuration is successfully performed, the control terminal is authenticated, thereby preventing other illegal control terminals from controlling the household appliance, and ensuring the legality of controlling the household appliance.
Further, before the operation S1, the method further includes: obtaining, by the control terminal, device information of the household appliance waiting for network configuration, to make the control terminal search for the connection information of the household appliance matching a type of the household appliance in the device information.
In order to ensure the connection reliability of the household appliance, the control terminal will also obtain the device information of the household appliance waiting for configuration, for example, by scanning the identification code on the household appliance, thus the type of the household appliance can be identified, such as an air conditioner, a refrigerator, a TV, a washing machine, or the like. After the type of the household appliance is identified, it is also convenient to automatically filter the household appliance matching the type of the household appliance for connection when searching for connection information. In addition, after the control terminal obtains the device information of the household appliance waiting for configuration by scanning, the household appliance can be added to the control program to facilitate subsequent control.
Further, as shown in
S31, generating authorization guide prompt information after the network configuration is successfully performed, to make the control terminal generate an authorization request to a cloud server according to the authorization guide.

In order to realize control of the household appliance by the control terminal, after the network configuration is successfully performed, the authorization guide prompt information can be generated, so as to guide the control terminal to perform corresponding operations according to the authorization guide prompt. The authorization guide prompt information includes, for example, “The preset button executes the preset operation,” “Bring the control terminal close to the household appliance,” and the like. When the corresponding operation is triggered, an authorization request is generated, and the generated authorization request is sent to the cloud server. When the cloud server receives the authorization request, the control terminal is authenticated, and the authorization response is returned after the authorization is successful. Therefore, when the control terminal receives the authorization response from the household appliance, it determines that the household appliance has been authenticated.
In some embodiments of the present disclosure, through the authorization guide prompt information, after the network is configured for the household appliance, the control terminal can complete the authorization more quickly and efficiently, to reliably control the household appliance.

S34, determining that the control terminal has been authenticated in response to receiving the authorization response from the cloud server.
After the network is successfully configured for the household appliance, since the control terminal needs to be authenticated, if the household appliance is a WiFi type device, it is necessary to press the preset hot key for a long time, such as the WiFi button on the household appliance or the remote control of the household appliance. When the cloud server receives the authorization request, it sends the authorization request to the household appliance, and the household appliance is authenticated by pressing the preset hot key for a long time. When the preset hot key is triggered by a long press, the household appliance generates an authorization response to the cloud server. After receiving the authorization response, the cloud server determines the legitimacy of the control terminal, and returns the authorization response to the control terminal. When receiving the authorization response from the household appliance, it is determined that the household appliance device has been authenticated, and then the household appliance can be controlled.
In technical solutions of the present disclosure, the preset hot key is set to trigger the authorization, which is convenient to operate, simple and reliable, not only improves the efficiency of configuring the network, but also reliably controls the household appliance.
In still another embodiment, as shown in
S36, sending a signal strength of the control terminal to a server, and sending an authorization request to a cloud server after the network configuration is successfully performed, for the cloud server to determine whether a distance between the control terminal and the household appliance is within a preset distance range according to the signal strength of the control terminal, and in response to that the distance between the control terminal and the household appliance is within the preset distance range, returning an authorization response; and
S37, determining that the control terminal has been authenticated in response to receiving the authorization response.
After the network configuration is successfully performed, the control terminal is moved to the preset distance range from the household appliance, and then the authorization is triggered. The signal strength of the control terminal is sent to the cloud server. According to the signal strength of the control terminal, the cloud server calculates the distance between the control terminal and the household appliance, and determines whether the distance between the control terminal and the household appliance is within the preset distance range. When the distance between the control terminal and the household appliance is within the preset distance range, it is determined that the control terminal has been authenticated, and then the cloud serve returns the authorization response to the control terminal.
The embodiments of the present disclosure further provide a method for configuring a network for a household appliance, which is applied to the household appliance end. As shown in
S4, sending, by the household appliance, a network configuration connection request, the network configuration connection request includes connection information of the household appliance, to make a control terminal send network configuration information after connecting with the household appliance through the connection information.
When the household appliance needs to perform network configuration, a network configuration connection request is sent so that other devices can discover the household appliance and establish a connection with the household appliance. Therefore, the control terminal can find the household appliance by searching, and establish a connection with the household appliance. Then, the control terminal sends the network configuration information corresponding to the household appliance to the household appliance through the established communication link. Further, in order to improve the speed of the network configuration, when the household appliance is powered on, it automatically sends a network configuration connection request. The household appliance can first determine whether the network has been configured, and if not, the household appliance sends the network configuration connection request. When the household appliance is a Bluetooth device, the household appliance sends the network configuration connection request by starting a Bluetooth broadcast; or when the household appliance is a WiFi device, the household appliance sends the network configuration connection request by starting a wireless access point.
S5, receiving the network configuration information sent by the control terminal, and performing network configuration according to the received network configuration information.
After receiving the network configuration information sent by the control terminal, the household appliance can perform network configuration according to the network configuration information. For example, the network configuration includes information of routers connected to the network, so that the household appliance can be connected to the router, and logged into the server through the router, so as to bind the household appliance and the control terminal, and so on.
S6, authenticating the control terminal after the network configuration is successfully performed, to realize control of the household appliance by the control terminal.
In the implementations of the present disclosure, the household appliance waiting for configuration sends the network configuration connection request, that is, the connection information for the control terminal to connect. After the connection is established, the system can receive the network configuration information from the control terminal and configure the network quickly and effectively based on the received network configuration information. After successfully configuring the network, the household appliance is authenticated, which prevents other illegal control terminals from controlling the household appliance and ensures the legitimacy of controlling the household appliance.
Further, in an embodiment, after the network is successfully configured for the household appliance, since the control terminal needs to be authenticated, if the household appliance is a WiFi type device, it is necessary to press the preset hot key for a long time, such as the WiFi button on the household appliance or the remote control of the household appliance. When the preset hot key is triggered by pressing for a long time, the control terminal is authenticated. After receiving the authorization request, the household appliance will confirm the right of the control terminal to determine the validity of the control terminal, and return the authorization response after the authorization is successful. The authorization can be carried out by the household appliance, or the authorization can be uploaded by the household appliance to the cloud server for authorization. When receiving the authorization response from the household appliance, it is determined that the household appliance has been authenticated, and then the household appliance can be controlled.
In technical solutions of the present disclosure, the preset hot key is set to trigger the authorization, which is convenient to operate, simple and reliable, not only improves the efficiency of configuring the network, but also reliably controls the household appliance.
In another embodiment, as shown in
S61, determining whether a preset button of the household appliance is triggered after the network configuration is successfully performed; and
