Referring to fig. 1, fig. 1 is a schematic diagram of an application environment suitable for the embodiment of the present application. The network switching method provided by the embodiment of the application can be applied to an intelligent home system as shown in fig. 1, and the intelligent home system comprises a first device 1 and a second device 2.

Wherein the first device 1 may be used to join a distributed network and/or create a centralized network and the second device 2 may be used to join a distributed network and/or a centralized network. The first device 1 may be a gateway device, etc., and the second device 2 may be a Personal Computer ((Personal Computer, PC), mobile phone, tablet Computer, wearable electronic device, routing device, server, etc.), or may be a sleep device, where the sleep device wakes up when operating, turns on a wireless receiving and transmitting function when waking up, and turns off the wireless receiving and transmitting function when sleeping, and may join a distributed network or a centralized network, in the present embodiment, the routing device mainly refers to a device that starts a network forwarding and broadcasting function from a small network, such as a router device in a zigbee network, and is not limited in this embodiment, the first device 1 may join a distributed network or establish a communication connection with the second device 2 in the distributed network, so as to broadcast preset centralized network configuration information in the distributed network, so that the second device 2 in the distributed network acquires the centralized network configuration information, and then switches from the distributed network to the network based on the centralized network configuration information, where the centralized network architecture refers to centrally store the centralized network configuration information in the central server, and then may submit the centralized network configuration information to the central server for the same server to work safely, and then download the server; the distributed network architecture is that a Computer can be provided as a server with a version centralized storage function, but the server is only used for facilitating the modification of exchanging people, is not used as the server, is only inconvenient to exchange and modify, and each Computer has a separate development environment, the method does not need networking, runs locally directly, and has a much higher safety factor compared with a centralized method, for example, a zigbee3.0 network usually belongs to a distributed network.

The first device 1 and the second device 2 can communicate with each other in a wireless manner such as bluetooth, NFC, infrared, and the like. For example, data transmission between the first device 1 and the second device 2 may be performed in a bluetooth manner, or may be performed through NFC, which is not limited in this embodiment of the present application. It should be understood that the above application environment is only an exemplary description for facilitating understanding of the following embodiments, and does not set any limit to the application environment in which the embodiments of the present application can be actually implemented.

Referring to fig. 2, a network handover method provided in an embodiment of the present application can be applied to the first device shown in fig. 1, where the network handover method includes but is not limited to S101, S103, and S105, and is specifically introduced as follows:

s101, the first device establishes communication connection with at least one second device in the distributed network.

The first device is a device to create or open a centralized network, and may specifically be a gateway device or the like. The first device establishes a communication connection with at least one second device in the distributed network, where the first device establishes a communication connection with at least one second device in the distributed network without joining the distributed network, or the first device joins the distributed network to establish a communication connection with at least one second device in the distributed network. It can be understood that, when a first device joins a distributed network, the first device will automatically establish a communication connection with at least one second device in the distributed network, and at this time, the first device can directly perform information transmission with a plurality of second devices, and the information transmission speed is high. When the first device does not join the distributed network, the operation required for joining the distributed network does not need to be executed, and resources can be effectively saved.

S103, the first device broadcasts preset centralized network configuration information in the distributed network based on the communication connection.

The first device broadcasts preset centralized network configuration information in the distributed network based on the communication connection, and the following two ways may be adopted: firstly, under the condition that a first device joins a distributed network, preset centralized network configuration information is directly sent to at least one second device through communication connection established between the first device and the at least one second device in the distributed network, so that the centralized network configuration information is broadcasted in the distributed network, and the information transmission efficiency can be effectively improved; secondly, under the condition that the first device does not join the distributed network, sending preset centralized network configuration information to at least one second device in the distributed network through communication connection established between the first device and the second device, so that the second device broadcasts the centralized network configuration information in the distributed network, and the stability and the safety of information transmission can be effectively improved. Wherein the centralized network configuration information is used to indicate how to join the centralized network created by the first device.

S105, the first device creates a centralized network, and all the second devices in the distributed network are switched to the centralized network according to the centralized network configuration information.

The first device may create a centralized network actively, or may create a centralized network passively. If the first device actively creates the centralized network, the first device may switch to the coordinator after broadcasting the preset centralized network configuration information in the distributed network, and start to create the centralized network, that is, create the centralized network corresponding to the preset centralized network configuration information, and after all the second devices in the distributed network search the centralized network, add the second devices to the centralized network according to the centralized network configuration information, thereby implementing switching from the distributed network to the centralized network. Therefore, the creating efficiency of the centralized network can be effectively improved, and the convenience is high. If the first device passively creates the centralized network, after broadcasting preset centralized network configuration information in the distributed network, the first device may create the centralized network based on a received centralized network creation instruction, and all second devices in the distributed network may switch to the centralized network according to the centralized network configuration information. Therefore, the centralized network is created after the centralized network creation instruction is received, so that the resource consumption can be effectively saved, and the flexibility of creating the centralized network is improved.

In some embodiments, before the first device creates the centralized network, the method further includes: exiting the distributed network. Before creating the centralized network, if the first device has joined the distributed network, the first device needs to exit the distributed network in a preset manner, and then create the centralized network corresponding to the centralized network configuration information. Here, if the first device has joined the distributed network, after the first device broadcasts the preset centralized network configuration information in the distributed network, the first device needs to exit the distributed network first, and then create the centralized network corresponding to the centralized network configuration information. Therefore, the centralized network is established after the distributed network is quitted, and the resource consumption can be effectively saved.

In the embodiment of the application, a first device establishes a communication connection with at least one second device in a distributed network, and broadcasts preset centralized network configuration information in the distributed network based on the communication connection to create the centralized network, and all the second devices in the distributed network are switched to the centralized network according to the centralized network configuration information.

In some embodiments, the establishing, by the first device, a communication connection with at least a second device in a distributed network includes:

the method comprises the steps that a first device receives a network access operation instruction which is sent by a terminal device and used for indicating to join a distributed network;

and the first equipment responds to the network access operation instruction and joins the distributed network to establish communication connection with at least one second equipment in the distributed network.

Here, the terminal device may be installed with an application program for managing the joining of the first device to the distributed network and/or the creation of the centralized network, and a user may perform a configuration operation on the first device through an operation interface corresponding to the application program displayed on the terminal device, for example, instruct the first device to join the distributed network, where after receiving a network entry operation instruction sent by the terminal device and used for instructing the joining of the distributed network, the first device may join the corresponding distributed network in response to the network entry operation instruction, so as to establish a communication connection with at least one second device in the distributed network. It will be appreciated that when a first device joins the distributed network, the first device will automatically establish a communication connection with at least a second device in the distributed network. In addition, the network access operation instruction may include information of a distributed network to be joined, and the like. Therefore, the first device can timely join the distributed network after acquiring the network access operation instruction, the operation is simple and convenient, and the user experience is further improved. In addition, the first device may also be configured as a routing device to perform a network access operation in advance through an application installed on the terminal device, such as a mobile phone app, and join the distributed network using the first device.

the method comprises the steps that a first device obtains connection signal strength between the first device and all second devices supporting short-distance wireless communication in the distributed network;

the first device establishes a short-distance wireless communication connection with at least one second device of which the connection signal strength meets a preset connection condition.

It can be understood that, in the distributed network, there may be a plurality of second devices that support short-range wireless communication and are all within an effective communication range of the first device, and the first device may only need to establish short-range wireless communication connection with one of the second devices, at this time, the first device may first acquire connection signal strength between all the second devices that support short-range wireless communication in the distributed network, and specifically may acquire the connection signal strength in a scanning manner or the like, and then select at least one second device from which the connection signal strength satisfies a preset connection condition to establish short-range wireless communication connection. Wherein the close range wireless communication connection includes, but is not limited to, bluetooth, NFC, infrared, and the like. The preset connection condition refers to a signal strength condition which is preset and needs to be met for establishing the short-distance wireless communication connection between the first device and the second device, and the connection condition may be set according to actual needs, for example, the connection condition may be set to select the second device with the best connection signal strength, that is, to establish the short-distance wireless communication connection with the second device with the best connection signal strength, and after the first device acquires the connection signal strength values with all the second devices supporting the short-distance wireless communication in the distributed network, the first device determines the maximum connection signal strength value therein, and establishes the short-distance wireless communication connection between the second devices corresponding to the maximum connection signal strength value. In addition, after acquiring all the second devices supporting the short-range wireless communication in the distributed network, the first device may display all the second devices supporting the short-range wireless communication in the distributed network, and then establish the short-range wireless communication connection with the second device selected by the user. Therefore, the first device establishes the short-distance wireless communication connection by selecting at least one second device with the connection signal strength meeting the preset connection condition, the reliability of the communication connection is ensured, and the user experience is further improved.

In some embodiments, the first device broadcasts, based on the communication connection, predetermined centralized network configuration information in the distributed network, including:

the first device sends preset centralized network configuration information to at least one second device in the distributed network based on the communication connection, and the at least one second device broadcasts the centralized network configuration information in the distributed network.

Specifically, when a first device joins a distributed network, the first device directly sends preset centralized network configuration information to at least one second device in the distributed network through a communication connection established between the first device and the at least one second device, so as to broadcast the centralized network configuration information in the distributed network; and under the condition that the first device does not join the distributed network, sending preset centralized network configuration information to at least one second device in the distributed network through a communication connection established between the first device and the second device, so that the second device broadcasts the centralized network configuration information in the distributed network. It can be understood that, because there is a direct or indirect communication connection between any two second devices in the distributed network, when obtaining the centralized network configuration information, any one second device may transmit the centralized network configuration information to another second device, thereby implementing broadcasting of the centralized network configuration information in the distributed network. Therefore, the first device sends the preset centralized network configuration information to at least one second device in the distributed network, so that the at least one second device broadcasts the centralized network configuration information in the distributed network, all the second devices in the distributed network can know the centralized network configuration information, the operation is simple and convenient, and the user experience is further improved.

Referring to fig. 3, another aspect of the embodiment of the present application further provides a network handover method, which can be applied to the second device shown in fig. 1, including but not limited to S201, S203, and S205, and is specifically described as follows:

s201, the second device establishes communication connection with the first device in the distributed network.

The first device is a device to create or open a centralized network, and may specifically be a gateway device or the like; the second device may be a device that can join a distributed network and/or a centralized network, and may specifically be a routing device or a dormancy device. When a second device in the distributed network establishes a communication connection with a first device, the first device may be added to the distributed network or may not be added to the distributed network. It will be appreciated that when a first device joins a distributed network, the first device may automatically establish a communication connection with a second device that is in the distributed network.

S203, the second device obtains preset centralized network configuration information broadcasted by the first device in the distributed network through the communication connection.

Here, the second device obtaining the preset centralized network configuration information broadcasted by the first device in the distributed network through the communication connection may include the second device directly or indirectly receiving the preset centralized network configuration information sent by the first device through the communication connection to obtain the preset centralized network configuration information broadcasted by the first device in the distributed network. Wherein the centralized network configuration information is used to indicate how to join the centralized network created by the first device. In some embodiments, the obtaining, by the second device, preset centralized network configuration information broadcasted by the first device in the distributed network through the communication connection includes: and the second equipment receives preset centralized network configuration information sent by the first equipment through the communication connection and broadcasts the centralized network configuration information in the distributed network. When the first device joins or does not join the distributed network, the second device may directly broadcast the centralized network configuration information in the distributed network after receiving preset centralized network configuration information sent by the first device through the communication connection.

S205, the second device switches from the distributed network to the centralized network created by the first device according to the centralized network configuration information.

Since the centralized network configuration information indicates how to join the centralized network created by the first device, the second device can switch from the joined distributed network to the centralized network created by the first device according to the centralized network configuration information to realize switching from the distributed network to the centralized network.

In the embodiment of the application, after the second device in the distributed network establishes a communication connection with the first device, the first device acquires, through the communication connection, the preset centralized network configuration information broadcasted in the distributed network by the first device, and switches from the distributed network to the centralized network created by the first device according to the centralized network configuration information, so that the device that needs to create the centralized network broadcasts the preset centralized network configuration information in the distributed network, so that the device in the distributed network can automatically switch from the distributed network to the centralized network according to the centralized network configuration information, manual operation by a user is not needed, and the operation is convenient and fast.

In some embodiments, the switching, by the second device, from the distributed network to the centralized network created by the first device according to the centralized network configuration information includes: and after exiting the distributed network according to a preset mode, the second equipment is added into the centralized network established by the first equipment according to the centralized network configuration information.

It can be understood that, since one device is not allowed to exist in both the distributed network and the centralized network, if a second device wants to join the centralized network, the second device needs to quit the joined distributed network and join the centralized network created by the first device according to the configuration information of the centralized network. Here, the preset manner may be set according to actual needs, for example, the exit operation may be executed one by one in the order from front to back or from back to front according to the joining time, which is not limited in this embodiment. Therefore, after the second device exits the added distributed network, the second device is added into the centralized network, manual operation of a user is not needed, and user experience is further improved.

In some embodiments, after obtaining the preset centralized network configuration information broadcasted by the first device in the distributed network through the communication connection, the second device further includes: and saving the centralized network configuration information.

It can be understood that, after acquiring the preset centralized network configuration information broadcast by the first device in the distributed network through the communication connection, the second device may quickly join the centralized network created by the first device based on the centralized network configuration information in the following by saving the centralized network configuration information in time.

In addition, the network switching device and the network switching method provided by the above embodiments belong to the same concept, and specific implementation processes thereof are detailed in the method embodiments and are not described herein again.

In order to enable a more systematic understanding of the network switching method provided in the embodiments of the present application, different application scenarios are respectively combined and described below by specific examples. It should be noted that the device in this example may be a Router device or an endview device. The Router device is generally a long power supply type device, wireless receiving and transmitting are always in an open state, and a distributed network can be opened or a centralized network can be added. The Enddevice equipment is dormant equipment, is awakened when in work, is turned on when in awakening of wireless receiving and transmitting, is in a closed state when in dormancy, and can be added into a distributed network or a centralized network. The gateway generally contains a plurality of wireless technologies and is used as a network hub to forward messages to play a role in starting and stopping, and a user can realize remote control anytime and anywhere through the equipment.

Application scenario one

Assuming that only distributed networks exist in the current environment, the network handover principle is as follows: the user can configure the gateway as a routing device to execute network access operation through mobile phone app in advance, after the gateway is used for joining the distributed network, the centralized network information to be created by the gateway is published into the distributed network, the device originally in the distributed network receives the centralized network information and then stores the information and quits the original distributed network, the gateway is switched to a coordinator, the centralized network is started to be established, the device originally in the distributed network can safely and quickly join the centralized network created by the gateway due to the fact that the centralized network information is stored in advance, so that the whole network switching process is completed, the network switching can be completed completely without feeling the user, the user does not need any participation of the user in the middle, the network switching can be completed, and after the network switching is completed, the user can realize remote control.

Application scenario two

Assuming that only a distributed network exists in the current environment and at least one of the routing devices supports bluetooth or NFC, infrared or other wireless communication technologies, the network switching principle is as follows: after the gateway is connected with the routing equipment in the distributed network through wireless communication technologies such as Bluetooth, NFC, infrared and the like, the centralized network information to be created by the gateway is sent to the routing equipment, the centralized network information is broadcasted in the distributed network by the routing equipment, the equipment originally in the distributed network receives the centralized network information and then stores the information and quits the original distributed network, the gateway starts to build the centralized network, the equipment originally in the distributed network can safely and quickly join the centralized network created by the gateway due to the fact that the centralized network information is stored in advance, so that the whole network switching process is completed, the network switching is completely insensitive to users, the network switching can be completed without any participation of the users in the middle, and the users can realize remote control after the network switching is completed.

Based on the network handover principle, please refer to fig. 9, which is an exemplary network handover method provided in the present application, including the following steps:
