[0092] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.

[0093] The terms “comprising” and “having” and any variations thereof in the description of the embodiments of the present application are intended to cover the non-exclusive inclusion. For example, a process, method, system, product, or device including a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed, or can optionally include other steps or units inherent to the process, method, product, or device.

[0094] Hereinafter, the terms “first”, “second”, and the like are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features.

[0095] In the embodiments of the present application, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as “exemplary” or “for example” in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words “exemplary” or “for example” is intended to present concepts in a specific way.

[0096] In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specified. "And / or" in this paper is only a description of the relationship between the associated objects, which means that there are three relationships, for example, A and / or B, which means that there are three cases: A alone, A and B together, and B alone.

[0097] As described in the background, in the whole-house intelligent scene, the basic function of the intelligent device depends on the connected network. When the network is abnormal, it will affect the normal function of the intelligent device. As shown in FIG. 1, FIG. 1 is an interface display diagram of each intelligent device (such as device 1, device 2, device 3, device 4, device 5, device 6 in FIG. 1) in the whole-house intelligent scene on the terminal device. When the network is abnormal, each intelligent device will display an offline state, indicating that the function of the device cannot be normally used.

[0098] Generally, after the network is abnormal, some users will replace the network, such as replacing the network device (such as a router) connected to the intelligent device, to ensure the normal function of the intelligent device. However, the intelligent device needs to be reset and reconfigured after a series of steps such as re-networking before it can be connected to the new network. After resetting the device and reconfiguring the network, the preference settings and personalized settings saved by the user in the application (APP) of the intelligent device, the terminal, and the cloud server will be cleared. If you want to restore the previous preference settings, you need to configure them again. As shown in FIG. 2, FIG. 2 is an interface diagram of the preference settings of the intelligent lamp. After replacing the network, if you want to restore the preference settings shown in FIG. 2, you need to reconfigure the intelligent lamp, such as reconfiguring the brightness, color temperature, RGB color, and some custom settings. The process is complicated and time-consuming.

[0099] In addition, the process of resetting the device and reconfiguring the network is different for different intelligent devices. For example, security devices installed in high places need users to climb to a high place to reset the device and reconfigure the network, which is complicated. In addition, resetting and reconfiguring the intelligent device requires users to have a basic understanding of Internet of Things (IoT) devices and WIFI technology, so for some special groups such as the elderly, the process of resetting and reconfiguring the intelligent device is very complex.

[0100] In addition, when the intelligent device is offline, the user cannot determine whether the device is abnormal or the network is abnormal, so various recovery methods will be tried, resulting in a poor experience.

[0101] Based on the above problems, the embodiment of the present application provides a network replacement method. When the smart device cannot be connected with the first network through the gateway, the terminal device is connected with the smart device to establish a communication connection. The terminal device can send a network replacement instruction to the smart device through the established communication connection, so that the smart device replaces the network, without resetting the device, and the process is simple and time-consuming.

[0102] The network replacement method provided by the embodiment of the present application can be applied to an Internet of Things system. Exemplarily, the Internet of Things system can be, but is not limited to, a smart home system, a smart medical system, and a smart traffic system.

[0103] For ease of understanding, please refer to FIG. 3, which shows a structural schematic diagram of an Internet of Things system. As shown in FIG. 3, the Internet of Things system can include a plurality of devices and a server 130.

[0104] In the embodiment of the present application, the plurality of devices at least includes a terminal device 110 and at least one smart device 120. The terminal device 110 can be a control instruction input device, such as a mobile phone, a tablet, a control panel, etc.

[0105] The smart device 120 refers to an Internet of Things smart device. For example, in a smart home scenario, the smart device 120 can be a home device, such as a smart door lock, a smart sound box, a smart curtain, a smart air conditioner, a smart camera, a smart television, a sweeping robot, a smart socket, a smart table lamp, a smart refrigerator, a smart water heater, etc.

[0106] As an example, the terminal device 110 can provide a human-computer interaction interface. A user can view the network status (offline or online) of each smart device 120, the running information of the smart device 120, etc. on the human-computer interaction interface. The user can also input a control instruction on the human-computer interaction interface by clicking the screen or voice, etc. to control the running of each smart device 120. The user can also complete the preference configuration of each smart device 120 on the human-computer interaction interface, etc.

[0107] As an example, the terminal device 110 is installed with a device application. The terminal device 110 starts the device application to display the human-computer interaction interface. Taking a mobile phone as the terminal device and a smart life application as the device application as an example, when the mobile phone starts the smart life application, the human-computer interaction interface of the smart home system can be displayed.

[0108] In the embodiment of the present application, the terminal device 110 and the smart device 120 can be interconnected through a communication network. The communication network can use any known network communication protocol, such as Bluetooth, WiFi, near field communication (NFC), or any other suitable communication protocol.

[0109] In the embodiments of the present application, the terminal device 110 and the smart device 120 can be located in the same local area network, for example, the terminal device 110 and the smart device 120 can be connected to the same WiFi network.

[0110] In the embodiments of the present application, the server 130 can be a cloud server, and the server 130 can be used to manage the smart device 120. The server 130 stores configuration information of the smart device 120, such as supported communication types, device identifiers, and the like. The server 130 can also obtain running information and network status of each smart device 120, and send the running information and network status of each smart device 120 to the terminal device 110 for the user to view.

[0111] As an example, the terminal device 110 and the server 130 can establish a connection through a WiFi network, a 4th generation mobile communication technology (4G) network, a 5th generation mobile communication technology (5G) network, and the like. As an example, the smart device 120 and the server 130 can establish a connection through a WiFi network.

[0112] It should be noted that the architecture of the Internet of Things system shown in FIG. 3 is only one implementation manner of the embodiments of the present application, and in actual applications, the Internet of Things system can also include more or fewer devices, which is not limited herein.

[0113] The network replacement method provided by the embodiments of the present application will be described in detail below with reference to the drawings, taking a smart home system as an example.

[0114] To facilitate understanding of the network replacement method provided by the embodiments of the present application, the network configuration and the adding registration process of the smart device are first described in detail below. As an example, the terminal device is installed with a device application, and the user can start the device application through the terminal device. After the terminal device starts the device application, the terminal device displays a device display interface to the user. As shown in (a) of FIG. 4, the device display interface includes the smart devices (such as device 1, device 3, device 5, device 4, device 6, etc. in (a)) that have been added by the user. The device display interface includes a function control, and the user clicks the function control. The terminal device responds to the operation of the user and displays a function prompt box to the user. The function prompt box includes a function prompt for adding a device. When the user needs to add a smart device, the user operates the function prompt for adding a device, and the terminal device responds to the operation of the user and performs device scanning. As shown in (b) of FIG. 4, when the terminal device scans the smart device, the terminal device displays a device connection interface to the user, and the device connection interface includes the device name (such as device XXXX in (b)) of the scanned smart device and the connection control corresponding to the smart device. The user confirms whether the scanned smart device is correct based on the device name of the smart device in the device connection interface. If the user confirms that the scanned smart device is correct, the user can click the connection control of the smart device, the terminal device responds to the operation of the user, establishes a connection with the smart device, and displays a device adding interface to the user.

[0115] As shown in (c) of FIG. 4, the device adding interface includes the device name of the smart device and a network information input area. The network information includes a network name and a network password, and the network information input area includes a network name input area and a network password input area. The network name input area includes a selection control. When the user clicks the selection control, the terminal device displays the network names of all current networks (WiFi networks), and the user can select the network to which the smart device is to be connected from the network names of all the displayed networks. After the user selects the network to which the smart device is to be connected, the user can input the network password of the selected network in the network password input area.

[0116] As an example, the terminal device can search and query the network of the environment in which the terminal device is located to find all the networks provided by the gateway in the environment. Thus, after the user clicks the selection control, the terminal device can display all the found networks. Optionally, the gateway can be a router, a switch, etc. In some examples, the gateway can also be a wireless access point, a WiFi hotspot, etc., and the specific implementation is not limited and can be set according to actual needs.

[0117] In some examples, the user can also directly input the network to which the smart device is to be connected in the network name input area and input the network password of the network to which the smart device is to be connected in the network password input area.

[0118] When the user inputs the network information (network name and network password) of the network to which the smart device is to be connected in the network information input area, the terminal device can send the network information of the network to which the smart device is to be connected to the smart device.

[0119] As an example, the device adding interface further includes a determination control. When the user inputs the network information of the network to which the smart device is to be connected in the network information input area, the user can click the determination control, and the terminal device sends the network information of the network to which the smart device is to be connected to the smart device in response to the operation of the user.

[0120] To facilitate successful registration of the smart device, the terminal device can further send user information to the smart device. The user information can be a user ID. The user needs to register an account when using the device application for the first time or when adding a device for the first time. After the account registration, the user has a user ID. The devices added by the user are all associated with the user ID of the user, for example, the devices added by the user on the device display interface are all associated with the user ID of the user.

[0121] After receiving the network information and the user information, the smart device can connect to the network through the network information.

[0122] As an example, after receiving the network information, the smart device can initiate network connection to the gateway through the network information, so as to connect to the network provided by the gateway, such as a WiFi network, and use the network service through the network.

[0123] In the embodiment of the present application, after the smart device connects to the network, the smart device can send a registration request to the server through the network, wherein the registration request includes device information of the smart device, network information of the currently connected network (i.e. network information of the network to which the smart device is to be connected) and user information. The device information of the smart device includes a device name and a device identifier of the smart device. The device identifier refers to a unique identification code of the device. For example, the device identifier can be an SN code of the device.

[0124] After receiving the registration request sent by the smart device, the server adds the smart device to the user information in response to the registration request, associates the device information of the smart device with the user information, so as to realize the adding registration of the smart device. At the same time, the server stores the network information of the network currently connected by the smart device and the device identifier of the smart device in association.

[0125] In some examples, the smart device can further include device information of the smart device and user information in the registration request sent to the server through the network. After the smart device completes the addition registration on the server side through the registration request, the smart device sends current network information connected to the server, so that the server stores the current network information connected and the device identification of the smart device in association.

[0126] When the terminal device obtains the information that the smart device has been added to the registration from the server, the terminal device can prompt the user with prompt information that the smart device has been added successfully. Alternatively, the terminal device queries the information that the smart device has been added to the registration from the server, or the server sends the information that the smart device has been added to the registration to the terminal device after completing the addition registration of the smart device.

[0127] It can be understood that after the smart device is successfully added, the terminal device can display the smart device on the device display interface.

[0128] In some examples of the present application, the terminal device can also send a registration request for the smart device to the server. For example, after the terminal device establishes a connection with the smart device, the smart device can send device information of the smart device to the terminal device. For example, after the smart device receives the network information and the user information sent by the terminal device, the smart device sends the device information to the terminal device.

[0129] After the terminal device receives the device information of the smart device, the terminal device sends a registration request to the server, and the registration request includes the device information of the smart device, the network information of the network to be connected, and the user information. After the server receives the registration request sent by the terminal device, the server adds the smart device to the user information in response to the registration request, associates the device information of the smart device with the user information, to realize the addition registration of the smart device, and stores the network information and the device identification in association. When the terminal device obtains the information that the smart device has been added to the registration from the server, the terminal device can prompt the user with prompt information that the smart device has been added successfully.

[0130] In order to facilitate the abnormal prompt of the smart device when the smart device is offline, i.e., the smart device cannot connect to the network through the gateway, in the process of network configuration and addition registration of the smart device, the abnormal prompt can be set for the smart device. Please refer to FIG. 5, which is an interaction diagram of the addition of a smart device provided in an embodiment of the present application. The method shown in FIG. 5 can be applied to the Internet of Things system shown in FIG. 3. As shown in FIG. 5, the process of device addition can include steps S201 to S205.

[0131] S201, the terminal device receives a device addition operation of the user, displays a device addition interface, and the device addition interface includes a device prompt control and a network information input area.

[0132] The terminal device displays a device adding interface for the user in response to the device adding operation after receiving the device adding operation of the user. The specific process is described above and will not be repeated here.

[0133] In the embodiments of the present application, as shown in FIG. 6, the device adding interface includes a device reminding control, a device name of the smart device, and a network information input area.

[0134] The device reminding control refers to a selection control for whether to remind when the smart device is in an offline state.

[0135] The device reminding control is used for the user to select whether to perform device network connection exception prompt when the smart device is in an offline state. When the user needs to remind the smart device when the smart device is in an offline state, the device reminding control can be selected. When the user does not need to remind the smart device when the smart device is in an offline state, the device reminding control can not be selected.

[0136] In S202, the terminal device sends reminding function setting information and network information of a network to be connected to the smart device.

[0137] As an example, as shown in (a) of FIG. 7, the device adding interface further includes a determination control. When the user inputs the network information of the network to be connected by the smart device in the network information input area and selects the device reminding control, the user can click the determination control. The terminal device responds to the operation of the user and sends the network information and the reminding function setting information to the smart device.

[0138] As an example, as shown in (b) of FIG. 7, the device reminding control includes a device offline reminding control and a device offline non-reminding control. When the user needs to remind the smart device when the smart device is in an offline state, the device offline reminding control can be selected. When the user does not need to remind the smart device when the smart device is in an offline state, the device offline non-reminding control can be selected. After the user inputs the network information of the network to be connected by the smart device in the network information input area and selects the device offline reminding control and the device offline non-reminding control, the terminal device can send the network information and the reminding function setting information to the smart device.

[0139] The reminding function setting information refers to information obtained according to the device reminding control. When the user selects the device reminding control or selects the device offline reminding control, the reminding function setting information includes information for performing device network connection exception prompt when the smart device is in an offline state. When the user does not select the device reminding control or selects the device offline non-reminding control, the reminding function setting information includes information for not performing device network connection exception prompt when the smart device is in an offline state.

[0140] As an example, the reminder function setting information includes a reminder field, which represents whether to perform device network abnormality prompt through different field values. For example, when the smart device is in an offline state, if device network abnormality prompt is needed, the field value is 1; if device network abnormality prompt is not needed, the field value is 0.

[0141] It can be understood that, in order to facilitate the successful registration of the smart device, the terminal device also sends user information to the smart device when sending the reminder function setting information and the network information to the smart device.

[0142] In S203, the smart device receives the reminder function setting information and the network information of the network to be connected, accesses the network to be connected according to the network information, and sends a registration request to the server through the network to be connected.

[0143] After receiving the reminder function setting information, the network information, and the user information, the smart device can connect to the network to be connected through the network information, that is, initiate network connection to the gateway through the network information to connect to the network to be connected through the gateway.

[0144] When the smart device is connected to the network to be connected, the smart device can send a registration request to the server through the network to be connected, wherein the registration request includes device information of the smart device, network information of the network to be connected, reminder function setting information, and user information.

[0145] In S204, the server responds to the registration request of the smart device, performs device registration, and stores the association relationship between the reminder function setting information of the smart device and the device identifier of the smart device, and stores the association relationship between the network information of the network to be connected and the device identifier of the smart device.

[0146] After receiving the registration request sent by the smart device, the server responds to the registration request, adds the smart device under the user information, associates the device information of the smart device with the user information, to realize the addition registration of the smart device. Correspondingly, the server also stores the association relationship between the reminder function setting information of the smart device and the device identifier of the smart device, and stores the association relationship between the network information of the network to be connected and the device identifier of the smart device. In addition, the server also detects the network state of the added smart device, that is, detects whether the added smart device is offline.

[0147] As shown in FIG. 8, the device name of the registration request sent by the intelligent device to the server is Device1, the device identifier is SN1, the user information is userid, the network name is wifi ssid, the network password is wifi password, and the reminder function setting information is isNotify = 1 (indicating that the device needs to be prompted for network connection exception when in an offline state). After receiving the registration request of the intelligent device, the server associates the user information userid with device1 and SN1, and updates the devices associated with the same user information, i.e., adds the intelligent device with the device name device1 and the device identifier SN1 under the user information userid. The server stores the reminder function setting information isNotify = 1 of the intelligent device in association with SN1, and stores the network name wifi ssid and the network password wifi password in association with SN1, and then detects the network state of the intelligent device. It can be understood that the intelligent device with the name Device2 and the device identifier SN2 in FIG. 8 is an intelligent device associated with the user information userid before.

[0148] In some embodiments, after the intelligent device completes the addition registration on the server side, the intelligent device can also send the reminder function setting information and the network information of the network to be connected to the server, so as to store, by the server, the association relationship between the reminder function setting information of the intelligent device and the device identifier of the intelligent device, and the association relationship between the network information of the network to be connected and the device identifier of the intelligent device.

[0149] It can be understood that when the intelligent device is connected to the network to be connected, the network to be connected is the network currently connected by the intelligent device.

[0150] S205, the terminal device prompts the user with prompt information that the intelligent device is added successfully.

[0151] When the terminal device obtains the information that the intelligent device has been added and registered from the server, the terminal device can prompt the user with the prompt information that the intelligent device is added successfully, and can display the intelligent device on the device display interface.

[0152] As an example, the terminal device can also send a registration request for the intelligent device to the server. As an example, after receiving the network information of the network to be connected sent by the terminal device, the intelligent device detects whether it can successfully connect to the network according to the network information. If the intelligent device can successfully connect to the network according to the network information, the intelligent device sends a connection feedback to the terminal device.

[0153] The connection feedback includes device information of the smart device. After receiving the connection feedback, the terminal device sends a registration request for the smart device to the server, where the registration request includes device information of the smart device, network information of the network to be connected, reminder function setting information, and user information. After receiving the registration request sent by the terminal device, the server adds the smart device to the user information in response to the registration request, associates the device information of the smart device with the user information, to realize the addition registration of the smart device. Correspondingly, the server also stores the association relationship between the reminder function setting information of the smart device and the device identifier of the smart device, and the association relationship between the network information of the network to be connected and the device identifier of the smart device.

[0154] As an example, the terminal device can also send the reminder function setting information corresponding to the smart device and the network information of the network to be connected to the server after the smart device completes the addition registration on the server side. As an example, after the terminal device sends the network information of the network to be connected and the user information to the smart device, the smart device can connect to the network to be connected through the network information. When the smart device connects to the network to be connected, the smart device can send a registration request to the server through the network to be connected, where the registration request includes device information of the smart device and user information. After the terminal device obtains the information that the smart device has been added and registered from the server, the terminal device can send the reminder function setting information corresponding to the smart device and the network information of the network to be connected to the server, so that the server stores the association relationship between the reminder function setting information of the smart device and the device identifier of the smart device, and the association relationship between the network information of the network to be connected and the device identifier of the smart device.

[0155] It can be understood that the above is only an example of the addition of the smart device by the embodiments of the present application, and is not specifically limited. In some embodiments, other implementation manners can also be provided according to actual needs.

[0156] In the embodiments of the present application, the server detects the network state for each added smart device, and when detecting that the smart device is offline, that is, the smart device cannot be connected to the network, the server determines whether to perform device network exception prompting on the smart device according to the reminder function setting information corresponding to the smart device.

[0157] In order to enable the user to determine whether the smart device is in a network exception or the network is in an exception, in the embodiments of the present application, when detecting that the smart device is in an offline state, the server detects whether one or more target devices having the same user information and network information as the smart device are in an online state, and if the one or more target devices are all in an offline state, sends network exception information to the terminal device, and if at least one of the one or more target devices is in an online state, sends device exception information for the smart device to the terminal device.

[0158] The target device refers to other smart devices associated with the same user information and network information as the smart device currently in an offline state.

[0159] In the embodiments of the present application, when the server sends device abnormal information of the smart device to the terminal device, the server detects the reminder function setting information of the smart device, and performs device networking abnormality prompting when the reminder function setting information of the smart device is in an offline state. The server sends device abnormal information of the smart device to the terminal device. It can be understood that when the reminder function setting information of the smart device is in an offline state, the server does not need to send device abnormal information of the smart device to the terminal device.

[0160] Taking the smart device A as an example, the user information associated with the device A is set as userID, and the network name of the network information is set as wifi ssID. When the server detects that the device A is in an offline state, the server detects whether other smart devices associated with the userID and the wifi ssID are in an online state. If all the other smart devices associated with the userID and the wifi ssID are in an offline state, the server sends network abnormal information to the terminal device. If there is a device in an online state among the other smart devices associated with the userID and the wifi ssID, the server detects the reminder function setting information corresponding to the device A. If the reminder function setting information corresponding to the device A is in an offline state, the server sends device abnormal information of the device A to the terminal device. If the reminder function setting information corresponding to the device A is in an offline state, the server does not send device abnormal information of the device A to the terminal device. As shown in (a) of FIG. 9, the server detects that the other smart devices associated with the userID and the wifi ssID include the device B and the device C, and the device B and the device C are also in an offline state. The server sends network abnormal information to the terminal device. As shown in (b) of FIG. 9, the server detects that the device B and the device C are in an online state, and the reminder function setting information isNotify corresponding to the device A is in a field value 1, that is, in an offline state, device networking abnormality prompting is needed. Therefore, the server sends device abnormal information of the device A to the terminal device. As shown in (c) of FIG. 9, the server detects that the device B and the device C are in an online state, and the reminder function setting information corresponding to the device A is in a field value 0, that is, in an offline state, device networking abnormality prompting is not needed. Therefore, the server does not send device abnormal information of the device A to the terminal device.

[0161] As an example, the server detects whether the offline time of the one or more target devices is in the same time range as the smart device when detecting that the one or more target devices have the same user information as the smart device and are offline, and sends network anomaly information to the terminal device if the offline time is in the same time range. In this way, the accuracy of detection is improved.

[0162] In the embodiments of the present application, the terminal device prompts the user of a network anomaly after receiving the network anomaly information from the server. Correspondingly, the terminal device prompts the user of a device networking anomaly after receiving the device anomaly information from the server.

[0163] In the embodiments of the present application, the terminal device can prompt the user of a network anomaly or a device networking anomaly through voice, a pop-up window, or the like. The following takes a pop-up window as an example. As shown in (a) of FIG. 10, the terminal device pops up a network anomaly prompt of "Detected network wifi SSID anomaly, click to confirm" through a device application after receiving the network anomaly information from the server. As shown in (b) of FIG. 10, the terminal device pops up a device networking anomaly prompt of "Detected device A offline, click to view" through a device application after receiving the device anomaly information from the server.

[0164] The embodiments of the present application can prompt the smart device in a timely manner when the smart device is offline by setting an anomaly prompt for the smart device. In addition, the embodiments of the present application can accurately remind the user whether the smart device is in a device networking anomaly or a network anomaly based on the network information and user information corresponding to the smart device when the smart device is offline, which facilitates user operation and improves user experience.

[0165] It can be understood that the user can detect the abnormal smart device after receiving the device networking anomaly prompt, so that the offline smart device can be connected to the network. The user can restore the network by replacing the network or the like after receiving the network anomaly prompt.

[0166] Please refer to Fig. 11, which is a flowchart of the abnormality prompt according to an embodiment of the present application. As shown in Fig. 11, taking the smart device as device a as an example, the server detects whether other smart devices under the same user information and network information are offline after detecting that device a is offline. If there is a device in online state among the other smart devices, the server detects the prompt function setting information of device a and performs device networking abnormality prompt when device a is in offline state. If device a is not in offline state, the server does not perform device networking abnormality prompt. If device a is in offline state, the server sends device abnormality information to the terminal device, and the terminal device performs device networking abnormality prompt to the user. If all the other devices are in offline state, the server determines that the network is abnormal, sends network abnormality information to the terminal device, and the terminal device performs network abnormality prompt to the user. The terminal device inquires whether the user needs to replace the network in response to the operation of the user on the network abnormality prompt. If the user needs to replace the network, the server initiates replacement of the network of the device. If the user does not need to replace the network, the server prompts the user to repair the network.

[0167] After the user replaces the network, the smart device needs to be reset and reconfigured to access the new network environment, which is a complex process. In order to simplify the process, in the embodiment of the present application, the network replacement of the smart device is realized through the interaction between the terminal device and the smart device.

[0168] The following describes the replacement of the smart device from the second network to the first network as an example, wherein the second network refers to the historical network connected by the smart device, and the first network refers to the new network to be connected by the smart device, i.e. the new network to be replaced. Please refer to Fig. 12, which is one of the interaction diagrams of the network replacement method according to an embodiment of the present application. The method shown in Fig. 12 can be applied to the Internet of Things system shown in Fig. 3. As shown in Fig. 12, the network replacement method provided by the embodiment of the present application includes steps S301 to S305.

[0169] S301, when the smart device cannot connect to the first network through the gateway, the terminal device is in communication connection with the smart device.

[0170] In the embodiment of the present application, the gateway of the first network is different from the gateway of the second network, or the network information of the first network is different from the network information of the second network.

[0171] As an example, after the user replaces the gateway of the environment where the smart device is located, the network of the environment where the smart device is located is replaced, and the smart device cannot connect to the new network through the gateway. For example, the gateway corresponding to the second network is gateway A, the gateway corresponding to the first network is gateway B, the user first uses gateway A to provide the second network, the network of the environment where the smart device is located is the second network, and the smart device first accesses the second network through gateway A. When gateway A fails, the smart device cannot access the second network through gateway A, and the user replaces gateway A with gateway B. At this time, the network of the environment where the smart device is located is changed to the first network provided by gateway B.

[0172] As an example, when the user changes the network information of the network, the network of the environment where the smart device is located is replaced, and the smart device cannot connect to the new network through the gateway. For example, the gateway of the environment where the smart device is located is gateway A, the network information of the second network provided by gateway A is X1, and the smart device accesses the second network through the network information X1. When the user changes the network information of the network provided by gateway A to X2, the network provided by gateway A is changed from the second network to the first network, and the network information of the first network is X2.

[0173] It can be understood that the above is only an example of the network replacement scenario in the embodiments of the present application, and the network replacement scenario is not limited to the example in the embodiments of the present application. For example, when the user changes the network operator, the network of the environment where the smart device is located is replaced, and the embodiments of the present application do not make specific limitations.

[0174] In the embodiments of the present application, after the smart device is added and registered in the network configuration, the network information of the configured network is stored in the smart device. When the smart device is in an offline state, that is, not connected to the configured network, the smart device will continue to attempt to connect to the configured network based on the stored network information. When the user replaces the network of the environment where the smart device is located with the first network, the smart device is not configured for the first network, the smart device does not have the network information of the first network, and the smart device cannot connect to the first network through the gateway, that is, the smart device cannot initiate a connection to the gateway through the network information of the first network to access the first network.

[0175] Therefore, in the embodiments of the present application, when the smart device cannot connect to the first network through the gateway, it means that the smart device is in a state of being unable to access the first network through the gateway, that is, the smart device is in an offline state.

[0176] It can be understood that for the terminal device, since the terminal device has high configuration capability, after the network of the environment where the terminal device is located is replaced with the first network, the terminal device can also find the first network and connect to the first network.

[0177] In the embodiments of the present application, when the smart device cannot be connected to the first network through the gateway, in order to make the smart device connect to the network, the terminal device can initiate the network replacement of the smart device.

[0178] For example, the terminal device can initiate the network replacement of the smart device according to the network replacement operation by receiving the network replacement operation of the user.

[0179] For example, the terminal device receives the network replacement operation of the user for the network exception prompt. For example, after the terminal device prompts the user for the network exception, the user operates the network exception prompt, sends the network replacement operation to the terminal device, and the terminal device receives the network replacement operation. As shown in FIG. 13, after the terminal device pops up the network exception prompt of “detecting that the network wifi SSID has an exception, click to confirm” through the device application, the user clicks the prompt, and the terminal device can respond to the operation of the user to display the prompt box of the network exception on the device display interface of the device application. The prompt box includes the prompt of the network exception, the replacement control and the close control. The prompt of the network exception is used to prompt the user that the network wifi SSID is abnormal, whether to update the network information of the smart device under the network. If the user does not need to update the network information of the smart device under the network, click the close control, and the terminal device responds to the operation of the user to close the prompt box. If the user needs to update the network information of the smart device under the network, click the replacement control, and the terminal device can receive the network replacement operation of the user for the network exception prompt to replace the network information of all smart devices under the network.

[0180] As an example, the terminal device can also receive a network replacement operation initiated by the user for the smart device according to a device networking exception prompt. For example, after the terminal device prompts the user for a device networking exception, the user clicks the prompt, and the terminal device can respond to the user's operation to display a device display interface to the user through the device application, and the device display interface includes the smart device with a networking exception. The user can operate the smart device with a networking exception to initiate a network replacement operation for the smart device with a networking exception to the terminal device. As shown in FIG. 14, after the terminal device pops up a device networking exception prompt of "Device A is detected to be offline, click to view" through the device application, the user clicks the prompt, and the terminal device can respond to the user's operation to display a device display interface to the user, and the device display interface includes the smart device added by the user, and the smart device added by the user includes device A. When the user needs to replace the network connected by device A, the user operates device A on the device display interface (such as long pressing device A or clicking device A, etc.), and the terminal device responds to the user's operation to display an operation prompt box of device A to the user. The operation prompt box includes an operation prompt of replacing the network, and when the user selects the operation prompt, the terminal device responds to the user's selection operation to initiate a network replacement for device A.

[0181] As an example, the user can also actively initiate a network replacement operation for a single smart device. As shown in FIG. 15, the terminal device displays a device display interface to the user through the device application, and the device display interface includes the smart device added by the user. When the user needs to replace the network connected by a smart device (such as device 5 in the figure), the user operates device 5 on the device display interface (such as long pressing device 5 or clicking device 5, etc.), and the terminal device responds to the user's operation to display an operation prompt box of device 5 to the user. The operation prompt box includes an operation prompt of replacing the network, and when the user selects the operation prompt, the terminal device responds to the user's selection operation to initiate a network replacement for device 5.

[0182] As an example, the user can also actively send a network replacement operation for multiple smart devices. As shown in FIG. 16, the terminal device displays a device display interface to the user through the device application, and the device display interface includes a function control. The user clicks the function control, and the terminal device responds to the user's operation to display a function prompt box to the user. The function prompt box includes a one-key replacement function prompt, and when the user selects the function prompt, the terminal device responds to the user's operation to initiate a network replacement for multiple smart devices. For example, a network replacement is initiated for all smart devices on the device display interface.

[0183] It can be understood that the above is only an example of the terminal device receiving the user's network replacement operation and initiating the network replacement of the smart device, and is not a specific limitation. In some embodiments, other implementations can be implemented, and the specific settings can be made according to actual needs.

[0184] As an example, the terminal device can also actively detect the network state of the network connected by the smart device, and actively initiate the network replacement of the smart device when detecting that the network state of the network connected by the smart device is disconnected. The process of the terminal device initiating the network replacement of the smart device is not specifically limited in the embodiments of the present application, and can be set according to actual conditions.

[0185] In the embodiments of the present application, after the terminal device receives the user's network replacement operation, the terminal device initiates the network replacement of the smart device according to the network replacement operation, and then establishes a communication connection with the smart device.

[0186] In order to enable the terminal device and the smart device to successfully establish a communication connection, in the embodiments of the present application, when the smart device cannot be connected to the network provided by the gateway through the first communication type, the terminal device establishes a communication connection with the smart device through the second communication type.

[0187] The first communication type and the second communication type can be the same, and the first communication type and the second communication type can also be different.

[0188] As an example, the first communication type is a WiFi communication type, and the second communication type can be, but is not limited to, one of a Bluetooth communication type, a near field communication (NFC) type, and a WiFi communication type.

[0189] When the smart device cannot be connected to the network provided by the gateway through the WiFi communication type, the terminal device can establish a communication connection with the smart device through Bluetooth, near field communication, or WiFi. In this way, by selecting multiple communication types, the terminal device and the smart device can successfully establish a communication connection, and the communication type with convenient operation can be selected for the smart device to establish a communication connection, further improving the convenience of network replacement.

[0190] It can be understood that when the network is abnormal and multiple smart devices cannot be connected to the first network through the gateway by using the first communication type, the terminal device can establish a communication connection with the multiple smart devices, and the communication types used by the terminal device and the multiple smart devices to establish the communication connection can be the same or different.

[0191] Exemplarily, when the plurality of smart devices cannot be connected to the first network by the gateway in the first communication type, the terminal device establishes a communication connection with a first smart device in the plurality of smart devices in a second communication type, and establishes a communication connection with a second smart device in the plurality of smart devices in a third communication type.

[0192] The third communication type can be, but is not limited to, one of a Bluetooth communication type, a near field communication (NFC) type, and a WiFi communication type.

[0193] The second communication type is the same as or different from the third communication type. The first smart device is any one of the plurality of smart devices, and the second smart device is any one of the smart devices except the first smart device.

[0194] For example, when the second communication type is Bluetooth and the third communication type is near field communication (NFC), the terminal device can establish a communication connection with the first smart device in Bluetooth, and establish a communication connection with the second smart device in near field communication (NFC).

[0195] In the embodiment of the present application, since the smart device can access to the network in the WiFi communication type, that is, the smart device at least supports the WiFi communication type, the terminal device can establish a communication connection with the smart device in the WiFi communication type.

[0196] It can be understood that the first smart device and the second smart device are only examples of the embodiment of the present application, and are not a limitation on the plurality of smart devices. In some examples, the plurality of smart devices can further include a third smart device and a fourth smart device, and the terminal device establishes a communication connection with the third smart device and the fourth smart device in the same or different communication types.

[0197] S302, the terminal device sends a network replacement instruction to the smart device through the communication connection, the network replacement instruction including network information of the first network, and the network replacement instruction being used to instruct the smart device to replace the network connected by the smart device from the second network to the first network according to the network information of the first network.

[0198] In the embodiment of the present application, after the terminal device establishes a communication connection with the smart device, the terminal device can send the network replacement instruction including the network information of the first network to the smart device through the communication connection, so as to make the smart device replace the connected network from the second network to the first network.

[0199] As an example, the user can specify the first network to which the smart device is ready to connect through the terminal device.

[0200] Exemplarily, the terminal device prompts one or more candidate networks to the user, receives a confirmation operation of the user on the one or more candidate networks, and obtains the first network and the network information of the first network.

[0201] The candidate network refers to a network that the smart device can currently connect to. As an example, the terminal device can search for the network of the environment where the smart device is located, and determine the searched network as the candidate network. As an example, the terminal device can also determine the network that the terminal device has connected to and saved as the candidate network.

[0202] Exemplarily, the terminal device prompts one or more candidate networks to the user through voice or interface display. After prompting the one or more candidate networks to the user, the user can determine the first network that the smart device is ready to connect from the one or more candidate networks. The terminal device obtains the first network by receiving the confirmation operation of the user.

[0203] Taking prompting the one or more candidate networks to the user through interface display as an example, as shown in FIG. 17, the terminal device shows the candidate network interface to the user, and the candidate network interface includes one or more candidate networks (such as network 1, network 2, network 3, etc. in FIG. 17). The user selects the candidate network in the candidate network interface, such as selecting the candidate network in the candidate network interface through clicking or other operations, to select the first network from the candidate network. The terminal device obtains the first network in response to the selection operation of the user on one or more candidate networks in the candidate network interface.

[0204] It can be understood that after the user selects the first network, if the terminal device stores the network information of the first network, the terminal device can directly send the network replacement instruction to the smart device through the communication connection. If the terminal device does not store the network information of the first network, such as the terminal device does not store the network password of the first network, the terminal device shows the network information input interface to the user after receiving the selection operation of the user on the first network in the one or more candidate networks, and the user can input the network information of the first network in the network information input interface. The terminal device sends the network replacement instruction to the smart device through the communication connection after receiving the network information of the first network input by the user.

[0205] As an example, the user can also input the network information of the first network that the smart device is ready to connect through the terminal device. Exemplarily, the terminal device can provide the network input interface to the user after establishing the communication connection with the smart device, and the user can directly input the network information of the first network that the smart device is ready to connect in the network input interface. The terminal device receives the network information of the first network input by the user, and sends the network replacement instruction to the smart device through the communication connection.

[0206] The embodiment of the present application prompts the candidate network to the user, facilitates the user to specify the network to which the smart device is ready to connect, and improves the convenience of user operation.

[0207] In some examples, considering that the terminal device and the smart device need to be in the same local area network, after the communication connection is established with the smart device, the terminal device can also determine the currently connected network as the first network, and then send the network replacement instruction to the smart device through the communication connection.

[0208] It can be understood that the above is only an example of the first network of the embodiment of the present application, and is not a specific limitation. In some embodiments, other implementation manners can also be implemented, and are set according to actual needs.

[0209] S303, the smart device receives the network replacement instruction from the terminal device through the communication connection, and replaces the connected second network to the first network according to the network information of the first network.

[0210] The smart device can initiate connection to the gateway to access the first network according to the network information of the first network in the network replacement instruction in response to the network replacement instruction after receiving the network replacement instruction sent by the terminal device, so as to replace the connected second network to the first network.

[0211] It can be understood that after the smart device accesses the first network, the smart device is in an online state, and the smart device can interact with other devices through the first network. For example, the smart device can interact with the server through the first network.

[0212] S304, the smart device sends device replacement information to the server through the first network, the device replacement information includes the network information of the first network and the device identifier of the smart device, and the device replacement information is used to indicate that the server stores the association relationship between the device identifier of the smart device and the network information of the first network.

[0213] In order to update the network state of the smart device in time, in the embodiment of the present application, after the network is replaced to the first network, the smart device sends the device replacement information to the server through the first network, and the device replacement information includes the network information of the first network and the device identifier of the smart device.

[0214] In the embodiment of the present application, the smart device sends the device replacement information to the server through the first network, can indicate the server that the smart device has replaced the network to the first network, has restored the online state, and can indicate the server to associate and store the device identifier of the smart device and the network information of the first network through the device replacement information.

[0215] S305, the server receives the device replacement information sent by the intelligent device, stores the association relationship between the device identifier of the intelligent device and the network information of the first network, and sends the network state of the intelligent device to the terminal device.

[0216] Wherein, after receiving the device replacement information sent by the intelligent device, the server stores the association relationship between the device identifier in the device replacement information and the network information of the first network, so as to facilitate the subsequent detection of network anomalies and the subsequent network replacement of the intelligent device, and facilitate the terminal device to obtain the network information of the intelligent device.

[0217] As an example, after receiving the device replacement information sent by the intelligent device, the server queries the network information of the historical network (such as the second network) associated with the intelligent device according to the device identifier of the intelligent device in the device replacement information, and after finding the network information of the historical network associated with the intelligent device, replaces the network information of the historical network with the network information of the first network, that is, updates the network information of the historical network associated with the intelligent device to the network information of the first network, so as to store the association relationship between the device identifier of the intelligent device and the network information of the first network.

[0218] In the embodiment of the application, after receiving the device replacement information sent by the intelligent device, the server can obtain that the intelligent device has recovered the online state through the device replacement information, and can interact information. Therefore, after receiving the device replacement information sent by the intelligent device, the server can update the network state of the intelligent device to the online state.

[0219] As an example, after the intelligent device replaces the connected second network with the first network, the intelligent device sends a connection feedback to the terminal device, and the terminal device sends the device replacement information of the intelligent device to the server after receiving the connection feedback sent by the intelligent device, so that the server stores the association relationship between the device identifier of the intelligent device and the network information of the first network, and updates the network state of the intelligent device to the online state.

[0220] In order to make the user know that the intelligent device has recovered the network state in time, the server can send the network state of the intelligent device to the terminal device after updating the network state of the intelligent device to the online state.

[0221] In the embodiments of the present application, after receiving the network status of the smart device sent from the server, the terminal device can prompt the user with the network status of the smart device to indicate the user that the smart device has recovered the online state and the network replacement has been completed. As an example, the terminal device updates the network status of the smart device to the online state in the device display interface to indicate the user that the smart device has recovered the online state. As an example, the terminal device can also indicate the user that the smart device has recovered the online state through voice prompt.

[0222] As an example, the terminal device can also actively acquire the network status of the smart device from the server. For example, the terminal device listens to the change of the network status of the smart device in the server, and acquires the network status of the smart device from the server after listening to the change of the network status of the smart device.

[0223] The embodiments of the present application establish the communication connection between the terminal device and the smart device, so that the terminal device and the smart device can directly interact the network information through the communication connection, complete the network replacement of the smart device, and do not need to reset the smart device and reconfigure the network of the smart device, which greatly simplifies the network replacement process, saves time, and improves efficiency.

[0224] In order to improve the reliability of data transmission, in the embodiments of the present application, after the terminal device and the smart device establish the communication connection, the terminal device and the smart device can first perform the reliability check of data transmission, and after the check is passed, the terminal device sends the network replacement instruction to the smart device. Please refer to FIG. 18, which is the second interaction schematic diagram of the network replacement method provided by the embodiments of the present application, and the method shown in FIG. 18 can be applied to the Internet of Things system shown in FIG. 3. As shown in FIG. 18, the network replacement method provided by the embodiments of the present application includes steps S401 to S407.

[0225] S401, when the smart device cannot connect to the first network through the gateway, the terminal device establishes a communication connection with the smart device.

[0226] The process of step S401 is referred to step S301, and will not be repeated here.

[0227] S402, the terminal device sends the check information to the smart device, and the check information includes the network information of the second network connected by the smart device and the device identifier of the smart device.

[0228] The network information of the second network to which the smart device is connected and the device identifier of the smart device can be obtained from the server. For example, after the terminal device initiates the network replacement for the smart device, the terminal device can send a network information request to the server to request the network information of the second network to which the smart device is connected and the device identifier of the smart device. After receiving the network information request sent by the terminal device, the server sends the network information of the second network to which the smart device is connected and the device identifier of the smart device to the terminal device in response to the network information request.

[0229] As an example, the terminal device can also store the network information of the network to which the smart device is connected and the device identifier of the smart device. For example, after completing the addition registration of the smart device or completing the network replacement, the terminal device stores the network information of the network to which the smart device is connected and the device identifier of the smart device. After the terminal device initiates the network replacement for the smart device, the network information of the second network to which the smart device is connected and the device identifier of the smart device are obtained from the stored network information.

[0230] After obtaining the network information of the second network to which the smart device is connected and the device identifier of the smart device, the terminal device sends the verification information to the smart device according to the network information of the second network to which the smart device is connected and the device identifier of the smart device.

[0231] S403, the smart device receives the verification information sent by the terminal device, and sends feedback information to the terminal device when the network information and the device identifier in the verification information are consistent with the network information and the device identifier stored by the smart device.

[0232] The smart device compares the network information in the verification information with the network information stored by the smart device, that is, compares the network information in the verification information with the network information currently connected by the smart device, and compares the device identifier in the verification information with the device identifier of the smart device. If the network information in the verification information is consistent with the network information currently connected by the smart device, and the device identifier in the verification information is consistent with the device identifier of the smart device, the smart device sends feedback information to the terminal device to indicate that the terminal device information is correct and the network replacement can be performed.

[0233] If the network information in the verification information is inconsistent with the network information currently connected by the smart device, and / or the device identifier in the verification information is inconsistent with the device identifier of the smart device, the feedback information does not need to be sent to the terminal device.

[0234] In the embodiment of the present application, if the smart device has multiple, the terminal device will send verification information for each smart device. For each smart device, feedback information will be sent to the terminal device only after receiving verification information consistent with the network information and the device identifier of the smart device.

[0235] S404, after receiving the feedback information of the smart device that the check information is checked through, the terminal device sends a network replacement instruction to the smart device through the communication connection.

[0236] Wherein, after receiving the feedback information of the smart device that the check information is checked through, the terminal device can obtain the result that the smart device can replace the network, therefore, after receiving the feedback information of the smart device, the terminal device can send a network replacement instruction to the smart device through the communication connection.

[0237] It can be understood that the process of sending a network replacement instruction to the smart device through the communication connection refers to step S302, which will not be repeated here.

[0238] S405, the smart device receives the network replacement instruction from the terminal device through the communication connection, and replaces the connected second network to the first network according to the network information of the first network.

[0239] S406, the smart device sends device replacement information to the server through the first network, the device replacement information includes the network information of the first network and the device identifier of the smart device, and the device replacement information is used to indicate the server to store the association relationship between the device identifier of the smart device and the network information of the first network.

[0240] S407, the server receives the device replacement information sent by the smart device, stores the association relationship between the device identifier of the smart device and the network information of the first network, and sends the network state of the smart device to the terminal device.

[0241] Wherein, the process of steps S405 to S407 refers to steps S303 to S305, which will not be repeated here.

[0242] For ease of understanding, the following will be illustrated by combining with FIG. 19. FIG. 19 is a schematic diagram of the network replacement scene provided by the embodiment of the application. As shown in FIG. 19, the terminal device first obtains the network information of the second network connected by the smart device and the device identifier from the cloud server, and the cloud server feeds back the network information of the second network connected by the smart device and the device identifier to the terminal device. The terminal device performs reliability check with the smart device according to the network information of the second network connected by the smart device and the device identifier fed back by the cloud server. After the check is passed, the terminal device sends a network replacement instruction to the smart device. After the smart device successfully replaces the network according to the network replacement instruction, the smart device sends device replacement information to the cloud server, and ends the replacement process.

[0243] The embodiment of the application can improve the reliability of data transmission by performing reliability check between the terminal device and the smart device after the communication connection is established between the terminal device and the smart device.

[0244] Considering that different smart devices support different communication capabilities, for example, some smart devices support Bluetooth communication type, some smart devices support near field communication (NFC), and some devices support WiFi communication. In order to further improve the convenience of network replacement, in the embodiment of the present application, the communication type for establishing a communication connection with the smart device can be determined according to the communication capability supported by the smart device. Please refer to FIG. 20, which is the third interactive schematic diagram of the network replacement method provided by the embodiment of the present application. The method shown in FIG. 20 can be applied to the Internet of Things system shown in FIG. 3. As shown in FIG. 20, the network replacement method provided by the embodiment of the present application includes steps S501 to S507.

[0245] S501, the terminal device obtains the communication type supported by the smart device.

[0246] The communication type supported by the smart device can be obtained through the configuration information of the smart device. For example, the smart device is configured with a Bluetooth module, so the smart device supports Bluetooth communication. For another example, the smart device is configured with a near field communication (NFC) module, so the smart device supports near field communication (NFC) communication.

[0247] As an example, the configuration information of the smart device is stored in the server, and the terminal device obtains the communication type supported by the smart device from the server. Optionally, the configuration information stored in the server is uploaded by the smart device, for example, after the smart device completes the addition registration, it sends its own configuration information to the server, that is, it sends the communication type supported by the smart device to the server. In some embodiments, the configuration information stored in the server is uploaded by the administrator.

[0248] For example, the terminal device receives the network replacement operation of the user, initiates a query request to the server, and the query request is used to request to query the communication type supported by the smart device. The server receives the query request of the terminal device, reads the configuration information of the smart device, obtains the communication type supported by the smart device, and sends the communication type supported by the smart device to the terminal device.

[0249] The process in which the terminal device receives the network replacement operation of the user can refer to step S301, which will not be described here.

[0250] When the terminal device receives the network replacement operation of the user, it initiates a query request to the server, requesting to query the communication type supported by the smart device. After receiving the query request sent by the terminal device, the server reads the configuration information of the smart device in response to the query request, obtains the communication type supported by the smart device, and feeds back the communication type supported by the smart device to the terminal device.

[0251] As an example, the configuration information of the smart device can also be stored in the terminal device, and the terminal device obtains the communication type supported by the smart device from the local. For example, the terminal device receives the network replacement operation of the user, and obtains the communication type supported by the smart device from the locally stored configuration information of the smart device. The actual requirement is set, and the embodiment of the application is not limited.

[0252] In S502, the terminal device obtains a target communication type for establishing a communication connection with the smart device according to the communication type supported by the smart device.

[0253] As an example, after the terminal device obtains the communication type supported by the smart device, the terminal device can determine any one of the communication types supported by the smart device as the target communication type. For example, the communication types supported by the smart device include a Bluetooth communication type, a near field communication (NFC) type, and a WiFi communication type, and any one of the Bluetooth communication type, the near field communication (NFC) type, and the WiFi communication type can be determined as the target communication type.

[0254] In order to ensure that the terminal device and the smart device can successfully establish a communication connection, as an example, the target communication type is one of the communication types supported by the terminal device and the smart device. For example, after the terminal device obtains the communication type supported by the smart device, the terminal device matches the communication type supported by the smart device with the communication type supported by the terminal device to obtain the communication type supported by the terminal device and the smart device. After obtaining the communication type supported by the terminal device and the smart device, the terminal device can select one of the communication types supported by the terminal device and the smart device as the target communication type. In this way, the communication connection is established based on the communication type supported by the terminal device and the smart device, which can improve the success rate of establishing the communication connection.

[0255] For example, the communication types supported by the smart device include a Bluetooth communication type and a WiFi communication type, and the communication types supported by the terminal device include a Bluetooth communication type, a near field communication (NFC) type, and a WiFi communication type. The terminal device matches the communication type supported by the smart device with the communication type supported by the terminal device to obtain the communication types supported by the terminal device and the smart device, which include the Bluetooth communication type and the WiFi communication type. Then, the terminal device can determine any one of the Bluetooth communication type and the WiFi communication type as the target communication type.

[0256] In order to further improve the convenience of network replacement, in the embodiments of the present application, the communication types are prioritized according to the operation convenience of the communication types. The target communication type is the one with the highest priority among the communication types supported by both the terminal device and the smart device, that is, the target communication type is the one with the highest operation convenience among the communication types supported by both the terminal device and the smart device. In this way, by establishing a communication connection using the communication type with the highest operation convenience priority, the convenience of network replacement can be further improved, the process of network replacement is simplified, time is saved, and efficiency is improved.

[0257] For example, the communication types supported by the terminal device and the smart device include a Bluetooth communication type and a WiFi communication type, and the priority of the Bluetooth communication type is higher than that of the WiFi communication type, and the target communication type is the Bluetooth communication type.

[0258] As an example, the priority of a near field communication (NFC) type is higher than that of the Bluetooth communication type, and the priority of the Bluetooth communication type is higher than that of the WiFi communication type.

[0259] In view of the user's preference requirements for communication types, in some examples, the terminal device can also prompt the user with recommendation information according to the priority of the communication types supported by both the terminal device and the smart device, and the recommendation information is used to recommend the communication type for the terminal device and the smart device to establish a communication connection.

[0260] For example, after obtaining the communication types supported by the smart device, the terminal device matches the communication types supported by the smart device with the communication types supported by itself to obtain the communication types supported by both the terminal device and the smart device. After obtaining the communication types supported by both the terminal device and the smart device, the terminal device can prompt the user with recommendation information according to the priority of the communication types supported by both the terminal device and the smart device.

[0261] As an example, the terminal device prompts the user with the recommendation information through voice or interface display, etc.

[0262] Taking the interface display as an example, after receiving the communication types supported by both the terminal device and the smart device, the terminal device can display a communication type recommendation interface to the user according to the priority of the communication types supported by both the terminal device and the smart device, and the communication type recommendation interface includes the recommended communication type, wherein the recommended communication type is the one with the highest priority among the communication types supported by both the terminal device and the smart device. As shown in (a) of FIG. 21, assuming that the communication type with the highest priority among the communication types supported by both the terminal device and the smart device is a near field communication (NFC), the terminal device can display the recommendation information "recommended to use NFC to establish a communication connection with the smart device" to the user on the communication type recommendation interface.

[0263] In some examples, the terminal device can also display the commonly supported communication types in the communication type recommendation interface according to the priority of the commonly supported communication types. As shown in (b) of FIG. 21, assuming that the communication types commonly supported by the terminal device and the smart device include a Bluetooth communication type and a WiFi communication type, and the priority of the Bluetooth communication type is higher than that of the WiFi communication type, the terminal device can display the recommendation information “recommend using Bluetooth connection, and recommend using WiFi connection when Bluetooth connection is unavailable” in the communication type recommendation interface. Alternatively, as shown in (c) of FIG. 21, the terminal device can display the recommendation information “preferentially recommend Bluetooth connection, and secondarily recommend WiFi connection” in the communication type recommendation interface. The specific content of the recommendation information can be set according to actual needs, and the embodiments of the present application do not make specific limitations.

[0264] After prompting the user with the recommendation information, the user can input the target communication type for establishing the communication connection between the terminal device and the smart device based on the recommendation information. The terminal device can obtain the target communication type for establishing the communication connection with the smart device in response to the user's communication type input operation on the recommendation information. It can be understood that the target communication type is the communication type input by the user. The target communication type includes the first communication type, the second communication type, and the third communication type, and can be one of the first communication type, the second communication type, and the third communication type.

[0265] As an example, the user can input the target communication type through voice or interface input, etc. Taking the interface display for prompting the user with the recommendation information as an example, as shown in FIG. 22, the communication type recommendation interface can further include a selection control of the recommended communication type, and the user can select the target communication type through the selection control. The terminal device obtains the target communication type in response to the user's operation.

[0266] S503, the terminal device establishes a communication connection of the target communication type with the smart device.

[0267] After obtaining the target communication type for establishing the communication connection with the smart device, the terminal device can establish a communication connection of the first communication type with the smart device.

[0268] Exemplarily, when the target communication type is a near field communication (NFC) type, the terminal device establishes a near field communication with the smart device. When the target communication type is a Bluetooth communication type, the terminal device establishes a Bluetooth communication with the smart device. When the target communication type is a WiFi communication type, the terminal device establishes a WiFi communication with the smart device.

[0269] S504, the terminal device sends a network replacement instruction to the smart device through the communication connection.

[0270] After the terminal device and the smart device establish the communication connection of the target communication type, the terminal device can send a network replacement instruction to the smart device through the communication connection.

[0271] In order to improve the reliability of data transmission, after the terminal device and the smart device establish the communication connection of the target communication type, the terminal device can also send verification information to the smart device. The smart device receives the verification information sent by the terminal device, and when the network information and the device identifier in the verification information are consistent with the network information and the device identifier stored by the smart device, the smart device sends feedback information to the terminal device. After receiving the feedback information of the verification pass of the smart device for the verification information, the terminal device sends a network replacement instruction to the smart device through the communication connection. For details, refer to steps S402 to S404, which are not described here.

[0272] S505, the smart device receives the network replacement instruction from the terminal device through the communication connection, and replaces the connected second network to the first network according to the network information of the first network.

[0273] S506, the smart device sends device replacement information to the server through the first network, the device replacement information includes the network information of the first network and the device identifier of the smart device, and the device replacement information is used to indicate the server to store the association relationship between the device identifier of the smart device and the network information of the first network.

[0274] S507, the server receives the device replacement information sent by the smart device, stores the association relationship between the device identifier of the smart device and the network information of the first network, and sends the network state of the smart device to the terminal device.

[0275] The processes of steps S504 to S507 refer to steps S302 to S305, which are not described here.

[0276] The terminal device according to the smart device supported communication type, and the smart device establishes a communication connection, which can improve the success rate of communication connection establishment. By selecting the communication type with the highest priority to establish a communication connection with the smart device, the user operation convenience can be further improved, and the user experience can be improved.

[0277] To further improve the convenience of user operation, in the embodiment of the present application, after obtaining the target communication type for establishing the communication connection with the smart device, the terminal device can prompt the user with operation guidance according to the target communication type, so as to facilitate the user to operate the terminal device and the smart device according to the operation guidance, and establish the communication connection between the terminal device and the smart device. Please refer to FIG. 23, which is the fourth interactive diagram of the network replacement method provided by the embodiment of the present application. The method shown in FIG. 23 can be applied to the Internet of Things system shown in FIG. 3. As shown in FIG. 23, the network replacement method provided by the embodiment of the present application includes steps S601 to S607.

[0278] S601, the terminal device acquires the communication types supported by the smart device.

[0279] S602, the terminal device obtains the target communication type for establishing the communication connection with the smart device according to the communication types supported by the smart device.

[0280] The processes of steps S601 to S602 refer to steps S501 to S502, which will not be repeated here.

[0281] S603, the terminal device prompts the user with the operation guidance corresponding to the target communication type, and establishes the communication connection of the target communication type with the smart device in response to the operation performed by the user based on the operation guidance corresponding to the target communication type, wherein the operation guidance corresponding to different communication types is different.

[0282] After obtaining the target communication type for establishing the communication connection with the smart device, the terminal device prompts the user with the operation guidance according to the target communication type, so as to facilitate the user to operate the terminal device and the smart device according to the operation guidance, and establish the communication connection of the target communication type between the terminal device and the smart device.

[0283] In the embodiment of the present application, the operation guidance corresponding to different communication types is different.

[0284] For example, when the target communication type is the Bluetooth communication type, the operation guidance prompted by the terminal device to the user is to turn on the Bluetooth switch of the terminal device and the smart device, so that the terminal device and the smart device are kept within a certain range.

[0285] When the target communication type is the near field communication (NFC) type, the operation guidance prompted by the terminal device to the user is to turn on the near field communication switch of the terminal device and the smart device, so that the terminal device and the smart device are in contact.

[0286] When the target communication type is the WiFi communication type, the operation guidance prompted by the terminal device to the user is to turn on the hotspot of the terminal device, and change the network information of the hotspot to the network information of the second network to which the smart device is connected.

[0287] After the user is prompted with the operation guide corresponding to the target communication type, the user can operate the terminal device and the smart device according to the operation guide. The terminal device responds to the operation of the user and establishes a communication connection of the first communication type with the smart device.

[0288] For example, when the target communication type is a Bluetooth communication type, the user turns on the Bluetooth switches of the terminal device and the smart device according to the operation guide, and makes the terminal device and the smart device stay within a certain range. The terminal device can then respond to the operation of the user and establish a communication connection of the Bluetooth communication type with the smart device.

[0289] It can be understood that when the smart device has established a Bluetooth channel with the terminal device in the registration and addition, when the Bluetooth switches of the terminal device and the smart device are turned on and the terminal device and the smart device stay within a certain range, the terminal device and the smart device can perform Bluetooth communication through the previously established Bluetooth channel. If the terminal device and the smart device have not established a Bluetooth channel before, when the terminal device and the smart device establish a communication connection of the Bluetooth communication type, the terminal device can perform Bluetooth pairing with the smart device to establish a Bluetooth channel, so as to perform Bluetooth communication through the Bluetooth channel.

[0290] For example, when the target communication type is a near field communication (NFC) type, the user turns on the near field communication switches of the terminal device and the smart device according to the operation guide, and makes the terminal device and the smart device contact. The terminal device can then respond to the operation of the user and establish a communication connection of the near field communication (NFC) type with the smart device.

[0291] For example, when the target communication type is a WiFi communication type, the user turns on the hotspot of the terminal device according to the operation guide, and changes the network information of the hotspot to the network information of the second network. The terminal device can then respond to the operation of the user and establish a communication connection with the smart device through the hotspot.

[0292] For example, when the target communication type is a WiFi communication type, the user turns on the hotspot of the terminal device according to the operation guide, and changes the network information of the hotspot to the network information of the second network. The terminal device can then respond to the operation of the user and establish a communication connection with the smart device through the hotspot.

[0293] (1) The terminal device prompts the user with network setting information according to the network information of the second network to which the smart device is connected. The network setting information is used to instruct the user to turn on the hotspot and change the network information of the hotspot to the network information of the second network.

[0294] As an example, after initiating the network replacement of the smart device, the terminal device initiates a network information request to the server to request the network information of the second network to which the smart device is connected. The second network refers to the historical network to which the smart device is connected, i.e., the network to be replaced.

[0295] The server receives the network information request sent by the terminal device, and sends network information of a second network to which the smart device is connected to the terminal device in response to the network information request.

[0296] As an example, the terminal device can also store the network information to which the smart device is connected, for example, after completing the addition registration of the smart device or completing the network replacement, the terminal device stores the network information to which the smart device is connected. After the terminal device initiates the network replacement of the smart device, the network information of the second network to which the smart device is connected is obtained from the stored network information.

[0297] After the terminal device obtains the network information of the second network to which the smart device is connected, the terminal device prompts the user with network setting information according to the network information of the second network to which the smart device is connected. The network setting information is used to instruct the user to turn on the hotspot and change the network information of the hotspot to the network information of the second network.

[0298] As an example, the terminal device can prompt the user with the network setting information through voice, interface display, etc. The specific implementation is not limited and can be set according to actual needs.

[0299] It can be understood that changing the network information of the hotspot to the network information of the second network can be changing the name of the hotspot to the network name of the second network and changing the password of the hotspot to the network password of the second network. Please refer to FIG. 24, which is a network setting information prompt interface provided by an embodiment of the present application. As shown in FIG. 24, after obtaining the network information of the second network to which the smart device is connected, the terminal device can display the network setting information prompt interface to the user. The network setting information prompt interface includes the prompt content "please turn on the hotspot, set the name of the hotspot to A, and set the password of the hotspot to B". A is the network name of the second network, and B is the network password of the second network.

[0300] The embodiment of the present application can improve the convenience of user operation and improve user experience by prompting the user with the network setting information.

[0301] (2) The terminal device receives the user's change operation on the network information of the hotspot, and establishes a communication connection with the smart device through the changed hotspot.

[0302] The terminal device prompts the user with the network setting information, and the user can turn on the hotspot of the terminal device and change the network information of the hotspot of the terminal device according to the prompt of the terminal device. The terminal device receives the user's change operation on the network information of the hotspot, and establishes a communication connection with the smart device according to the changed hotspot.

[0303] Understandably, the network information of the changed hotspot is consistent with the network information of the second network, and therefore the smart device can access the changed hotspot of the terminal device through the network information of the second network, so as to establish a communication connection with the terminal device through the changed hotspot.

[0304] Understandably, when the terminal device establishes a communication connection with the smart device through the changed hotspot, the terminal device can send a network changing instruction to the smart device through the changed hotspot.

[0305] The embodiments of the present application can further improve the convenience of user operation and improve user experience by guiding the user.

[0306] To further improve the convenience of operation, when there are multiple smart devices changing networks, the terminal device can obtain a target communication type corresponding to each smart device according to the priority of the communication type in the embodiments of the present application. The smart devices under the same communication type are obtained by dividing each smart device according to the target communication type corresponding to the smart device. For the smart devices under the same communication type, the user is prompted with the operation guide corresponding to the communication type.

[0307] For example, for each smart device, it is first detected whether the smart device supports the communication type with the highest priority. If the smart device supports the communication type with the highest priority, the target communication type corresponding to the smart device is determined to be the communication type with the highest priority, and the smart device is divided into the communication type list corresponding to the highest priority. If the smart device does not support the communication type with the highest priority, it is detected whether the smart device supports the communication type with the second priority. If the smart device supports the communication type with the second priority, the target communication type corresponding to the smart device is determined to be the communication type with the second priority, and the smart device is divided into the communication type list corresponding to the second priority. If the smart device does not support the communication type with the second priority, it is detected whether the smart device supports the communication type with the third priority, and so on, to obtain the smart devices under the same communication type.

[0308] After obtaining the smart devices under the same communication type, the smart devices included in each communication type and the corresponding operation guide can be displayed to the user, so as to instruct the user to operate according to the operation guide corresponding to each communication type, to establish a communication connection between the terminal device and the smart devices included in each communication type.

[0309] For example, the communication types include Bluetooth communication, near field communication (NFC), and WiFi communication, wherein the priority of the near field communication (NFC) is higher than that of the Bluetooth communication, and the priority of the Bluetooth communication is higher than that of the WiFi communication. Each smart device can be connected to at least a WiFi network. As shown in (a) of FIG. 25, the terminal device displays a prompt box for network anomaly on a device display interface of a device application. If the user clicks the replacement control in the prompt box, the terminal device receives the network replacement operation of the user for the network anomaly prompt, queries all smart devices under the network WiFi SSID from the server, and queries the communication types supported by the smart devices. As shown in (b) of FIG. 25, for each smart device, it is first detected whether the smart device supports near field communication (NFC). If the smart device supports near field communication (NFC), the smart device is divided into a near field communication (NFC) type list. If the smart device does not support near field communication (NFC), it is detected whether the smart device supports Bluetooth communication. If the smart device supports Bluetooth communication, the smart device is divided into a Bluetooth communication type list. If the smart device does not support Bluetooth communication, the smart device is divided into a WiFi communication type list. After the classification is completed, an operation guide interface is displayed to the user, as shown in (c) of FIG. 25. The operation guide page includes the smart devices included in the near field communication (NFC) type list and the operation guide corresponding to the near field communication (NFC) type, the smart devices included in the Bluetooth communication type list and the operation guide corresponding to the Bluetooth communication type, and the smart devices included in the WiFi communication type list and the operation guide corresponding to the WiFi communication type.

[0310] It can be understood that after the operation guide interface is displayed to the user, for the smart devices in each communication type list, the user can operate the terminal device and the smart device according to the operation guide corresponding to the communication type, and the terminal device responds to the operation of the user to establish a communication connection with the smart device.

[0311] The embodiments of the present application obtain the target communication type corresponding to the smart device according to the priority of operation portability, instruct the user to operate based on the operation guide corresponding to the target communication type, and can further improve the convenience during network replacement, and realize the user's unconscious replacement of the network connected by the device.

[0312] In S604, the terminal device sends a network replacement instruction to the smart device through the communication connection.

[0313] After the terminal device and the smart device establish the communication connection of the target communication type, the terminal device can send a network replacement instruction to the smart device through the communication connection.

[0314] In order to improve the reliability of data transmission, after the terminal device and the smart device establish a communication connection of the target communication type, the terminal device can further send verification information to the smart device. The smart device receives the verification information sent by the terminal device, and when the network information and the device identifier in the verification information are consistent with the network information and the device identifier stored by the smart device, the smart device sends feedback information to the terminal device. After receiving the feedback information of the verification passed by the smart device for the verification information, the terminal device sends a network replacement instruction to the smart device through the communication connection. For details, refer to steps S402 to S404, which are not described here.

[0315] S605, the smart device receives the network replacement instruction from the terminal device through the communication connection, and replaces the connected second network to the first network according to the network information of the first network.

[0316] S606, the smart device sends device replacement information to the server through the first network, the device replacement information includes the network information of the first network and the device identifier of the smart device, and the device replacement information is used to indicate the server to store the association relationship between the device identifier of the smart device and the network information of the first network.

[0317] S607, the server receives the device replacement information sent by the smart device, stores the association relationship between the device identifier of the smart device and the network information of the first network, and sends the network state of the smart device to the terminal device.

[0318] The processes of steps S604 to S607 refer to steps S302 to S305, which are not described here.

[0319] The embodiments of the present application can further improve the convenience of the user's operation when replacing the network and improve the user experience by prompting the user with the operation guide of the target communication type and instructing the user to operate according to the operation guide.

[0320] The embodiments of the present application can establish a communication connection of the target communication type between the terminal device and the smart device, so that the terminal device and the smart device can directly interact with the network information through the communication connection to complete the replacement of the network of the smart device without resetting and reconfiguring the network of the smart device. As shown in (a) of FIG. 26, in the conventional technology, the smart device needs to be reset, reconfigured, and reinitiated to register and add to the server, and three ends need to interact to realize the replacement of the network of the smart device. As shown in (b) of FIG. 26, the embodiments of the present application can make the smart device complete the replacement of the network through the interaction between the terminal device and the smart device, without resetting and reconfiguring the network of the smart device, so that the preference settings and personalized settings reserved by the server, the terminal device and the smart device are not cleared, greatly simplifying the process of network replacement, saving time and improving efficiency.
