Description

Technical Field

[0001] The present invention belongs to the technical field of wireless Internet of Things, and in particular relates to a multi-device networking method and system. Background Art

[0002] With the popularization of smart devices and wireless IoT technology, the networking and networking configuration management of smart devices have become increasingly important. In traditional device networking, all smart devices require users to manually enter routing information (i.e., the router's SSID and password) to achieve network configuration. However, the networking process in which users manually enter the network SSID and password one by one is cumbersome and error-prone, and it is impossible to achieve automatic configuration of multiple devices. The complex network configuration process affects the user experience.

[0003] In order to solve the defects of traditional networking methods, the industry has proposed a batch networking method for smart devices, which mainly includes: the user terminal obtains the combination relationship configuration table sent by the cloud; the user terminal searches for smart devices that meet the combination relationship configuration table, and confirms the target device combination that needs to be networked; then sends networking login information to the target device combination to connect the target device combination to the network.

[0004] In the above-mentioned prior art, the cloud is only responsible for the management of the association between the unique identifier of a single device and the unique identifier of the combined product in the combination relationship configuration table, and does not uniformly control the networking information and networking operations. The networking of all devices is performed after being re-selected and confirmed by the user terminal, which is still relatively cumbersome; moreover, since the networking information and networking operations are managed and controlled on the user terminal, the networking operation cannot be performed when the user terminal is inconvenient to use; in addition, for security reasons, users may regularly reset routing information (router name and password) or replace routers; when the router information is updated, the cloud of the above-mentioned prior art cannot timely manage and update the updated routing information. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-device networking method and system, aiming to improve the multi-device networking efficiency and networking configuration information management efficiency in routing change scenarios; the present invention is implemented through the following scheme.

[0006] A first aspect of the present invention provides a multi-device networking method, comprising:

[0008] S120: When the routing information is updated from the original routing information to the new routing information, the new routing information is configured to a first smart device connected to the original routing information and connected to the network;

[0009] S130: After the first smart device is connected to the network, the unique device identification code and the new routing information are uploaded to the cloud server, and the cloud server updates the original routing information of the first smart device in the routing configuration information table to the new routing information;

[0010] S140: The cloud server searches the routing configuration information table for other smart devices with the same original routing information as the first smart device, and sends the new routing information to each of the other smart devices;

[0011] S150: Each of the other smart devices is connected to the network according to the received new routing information;

[0012] S160: After the other smart devices are connected to the network, the cloud server updates the other smart devices that are successfully connected to the network with the new routing information.

[0013] As a preferred technical solution, in S110, the method for the cloud server to construct a routing configuration information table specifically includes:

[0014] S111: The user terminal registers a unique identification code of the user terminal with the cloud server;

[0015] S112: The user terminal obtains device unique identification codes from multiple smart devices respectively, reports to the cloud server and requests to be bound with the unique identification code of the user terminal;

[0016] S113: The cloud server obtains current routing information of multiple smart devices bound to the same unique identification code of the user terminal, and constructs the routing configuration information table.

[0017] As a preferred technical solution, the multiple smart devices in the routing configuration information table are divided into at least one group, the smart devices in each group are used to connect to the same routing information, and the smart devices in different groups are used to connect to different routing information.

[0018] As a preferred technical solution, in S120, the method of configuring the new routing information to the first smart device and connecting to the network specifically includes:

[0019] S121a: The user terminal connects to the network according to the new routing information;

[0020] S122a: The user terminal searches for hotspots released by smart devices in a state of waiting for network configuration, and selects any one of the smart devices in a state of waiting for network configuration as the first smart device;

[0021] S123a: The user terminal extracts the new routing information of its own networking and configures it to the first smart device, and the first smart device connects to the network according to the new routing information.

[0022] As a preferred technical solution, in S120, the method of configuring the new routing information to the first smart device and connecting to the network specifically includes:

[0023] S121b: Select any smart device in a state of waiting for network configuration as the first smart device;

[0024] S122b: The first smart device receives the input new routing information and connects to the network.

[0025] As a preferred technical solution, in S130, the method of updating the routing information of the first smart device in the routing configuration information table to the new routing information specifically includes:

[0026] S131: Acquire the new routing information through a DHCP server;

[0027] S132: Packing the first smart device's unique device identification code and the new routing information into a structured data format;

[0028] S133: Publishing the packaged data format to a specified MQTT topic server through the MQTT protocol;

[0029] S134: The cloud server subscribes to the corresponding topic of the MQTT topic server and parses the data format therein:

[0030] S135: Update the routing information of the corresponding smart device in the routing configuration information table according to the parsed device unique identification code and the new routing information.

[0031] As a preferred technical solution, S140 specifically includes:

[0032] S141: when updating the original routing information of the first smart device in the routing configuration information table to the new routing information, recording the original routing information of the first smart device;

[0033] S142: Searching the routing configuration information table for a smart device whose routing information is consistent with the original routing information of the first smart device and using the smart device as the other smart device;

[0034] S143: The cloud server directly sends the new routing information to each of the other smart devices via the MQTT topic server through the MQTT protocol.

[0035] As a preferred technical solution, in S150, when each of the other smart devices receives the new routing information, a prompt message is generated, and the prompt message displays the new routing information and provides an option of whether to connect to the Internet. After each of the other smart devices receives the indication to confirm the connection to the Internet, it connects to the Internet according to the new routing information.

[0036] As a preferred technical solution, the routing configuration information table also includes device networking status information of each smart device. The cloud server monitors the networking status of each smart device in real time and updates the device networking status information. The device networking status information includes networking status and disconnected status. In S140, when the cloud server searches for other smart devices with the same original routing information as the first smart device in the routing configuration information table, the smart devices whose device networking status information is that they are already connected to the network are eliminated.

[0037] The second aspect of the present invention provides a multi-device networking system, comprising: a user terminal, a cloud server and multiple smart devices that can be connected to each other via a wireless network; the user terminal, the cloud server and multiple smart devices cooperate with each other to execute the multi-device networking method described above.

[0038] The present invention provides a multi-device networking method and system. When the routing information is updated, during the entire networking process of multiple smart devices, one of the smart devices (i.e., the first smart device) actively initiates networking based on the new routing information. When the first smart device is connected to the network, it uploads its own device unique identification code and new routing information to the cloud server, and updates the routing information of the first smart device. Then, the cloud server distributes the updated new routing information of the first smart device to each other smart device with the same original routing information as the first smart device. After the networking of each of the other smart devices is completed, the cloud server updates each other smart device that has successfully connected to the network to the new routing information. As can be seen from the above, the cloud server in the present invention not only manages the binding information of the user terminal and multiple smart devices, but also can timely and automatically manage and update the network configuration information on the cloud server; moreover, when other smart devices with the same original routing information as the first smart device are connected to the network in batches, they can connect to the network by themselves without the need to be operated through the user terminal. The present invention can greatly improve the efficiency of multi-device networking and the management efficiency of networking configuration information in the scenario of routing information update, and can also enhance data security.

[0046] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. The terms "first" and "second" are only used for the purpose of distinction in the description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more, unless otherwise clearly defined.

[0047] The embodiments of the present invention provide a multi-device networking method and a corresponding networking system, aiming to improve the multi-device networking efficiency and networking configuration information management efficiency in a routing change scenario; the embodiments of the present invention are implemented through the following basic embodiments, specific embodiments, improved embodiments, etc., and the technical features in each specific embodiment can be used interchangeably without conflicting with each other. The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] like Figure 1 As shown, as a basic embodiment, the multi-device networking system provided by the present invention includes: a user terminal, a cloud server and multiple smart devices that can be connected to each other through a wireless network; the user terminal, the cloud server and multiple smart devices cooperate with each other to execute the multi-device networking method described below.

[0049] Among them, user terminals refer to devices used by users to access the network, such as laptops, smart phones, tablets, smart TVs, smart watches, etc. User terminals are connected to the Internet or local area network through various connection methods (such as Wi-Fi, wired network, cellular network, etc.), allowing users to obtain and share information and send instructions through user terminal application software.

[0050] Smart devices refer to devices that are equipped with controllers, sensors, functional modules and communication modules, and can be connected to wireless routers, and can monitor and automatically control the environment in which they are located, or automate the operation of specific objects. For example, smart devices include but are not limited to smart air conditioners, smart refrigerators, smart stoves, smart cameras, smart thermostats, smart speakers, smart TVs, etc. These smart devices can communicate with the Internet or local area network through wireless connection technologies (such as Wi-Fi, Bluetooth, Zigbee, etc.), allowing users to control and manage them through the application of the user terminal or its own control interface.

[0051] Cloud servers refer to servers and data centers that provide cloud computing services. They can connect to various smart devices and user terminals. User terminals and smart devices can obtain data resources from cloud servers and respond to control instructions from the cloud through the Internet.

[0052] Combination Figure 2 As shown, as a basic embodiment, the multi-device networking method provided by the present invention includes:

[0053] S110: The cloud server constructs a routing configuration information table, which includes: a unique identification code UUserID of the user terminal, a unique device identification code UDeviceID of each of the multiple smart devices bound to the user terminal, and routing information of each smart device connected to the network; wherein the routing information includes a routing ssid (name) and a routing password (password);

[0054] S120: When the routing information is updated from the original routing information to the new routing information, the new routing information is configured to a first smart device connected to the original routing information and connected to the network;

[0055] S130: After the first smart device is connected to the network, the unique device identification code and the new routing information are uploaded to the cloud server, and the cloud server updates the original routing information of the first smart device in the routing configuration information table to the new routing information;

[0056] S140: The cloud server searches the routing configuration information table for other smart devices with the same original routing information as the first smart device, and sends the new routing information to each of the other smart devices;

[0057] S150: Each of the other smart devices is connected to the network according to the received new routing information;

[0058] S160: After the other smart devices are connected to the network, the cloud server updates the other smart devices that are successfully connected to the network with the new routing information.

[0059] The format of an exemplary routing configuration information table is shown in Table 1 below:

[0060]

[0061] Table 1

[0062] Table 1 is used as an example for detailed explanation, wherein smart device A, smart device B, smart device C, and smart device D are multiple smart devices bound to user terminal 1, and smart device A, smart device B, smart device C, and smart device D are currently connected to the same wireless router, and the SSID of the current router is router A and the password is 12345678.

[0063] Assume that for security reasons, the user changes the ssid of the router to route B and / or changes the password to 87654321, thus generating new routing information. At this time, a smart device, such as smart device A, can be selected as the first smart device, and the new routing information can be configured for networking.

[0064] When smart device A is successfully connected to the Internet with the new routing information, the smart device A uploads its UDeviceID "smart device A" and the new routing information to the cloud server, and updates the original routing information of the smart device A in the routing configuration information table to the new routing information; the updated routing configuration information table is as shown in Table 2:

[0065]

[0066] Table 2

[0067] Afterwards, the cloud server searches for other smart devices with the same original routing information as smart device A in the routing configuration information table, and can search for smart device B, smart device C, and smart device D, and sends the new routing information to smart device B, smart device C, and smart device D, that is, the information with ssid being route B and password being 87654321.

[0068] Then, smart device B, smart device C, and smart device D are connected to the network respectively according to the received new routing information.

[0069] Finally, after the smart devices B, C, and D are connected to the network, the cloud server updates the other successfully connected smart devices with the new routing information. The updated routing configuration information table is as shown in Table 3:

[0070]

[0071] Table 3

[0072] Combination Figure 3 As shown, in step S110, the method for the cloud server to construct a routing configuration information table specifically includes:

[0073] S111: The user terminal registers a unique identification code of the user terminal with the cloud server;

[0074] S112: The user terminal obtains device unique identification codes from multiple smart devices respectively, reports to the cloud server and requests to be bound with the unique identification code of the user terminal;

[0075] S113: The cloud server obtains current routing information of multiple smart devices bound to the same unique identification code of the user terminal, and constructs the routing configuration information table.

[0076] Continue to see Figure 3 When the user terminal is bound to the corresponding smart device, the user terminal can operate and control the bound smart device; among them, the part in which the user terminal controls the bound smart operation belongs to the existing technology and will not be repeated in this article.

[0077] As a preferred embodiment, the multiple smart devices in the routing configuration information table are a group of smart devices connected to the same routing, or multiple groups of smart devices connected to multiple routings. The routing configuration information table corresponding to the multiple groups of smart devices connected to multiple routings is as shown in Table 4 below:

[0078]

[0079] Table 4

[0080] In the case where multiple groups of smart devices are connected to multiple routers respectively, when the corresponding routes are updated, the smart devices of the corresponding groups each execute steps S110-S160 of the above-mentioned multi-device networking method. In this way, multiple groups of smart devices and multiple routers can be networked and controlled through one UUserID and one routing configuration information table.

[0081] like Figure 4As shown, as an optional specific embodiment, in step S120, the method of configuring the new routing information to the first smart device and connecting to the network specifically includes:

[0082] S121a: The user terminal connects to the network according to the new routing information;

[0083] S122a: The user terminal searches for hotspots released by smart devices in a state of waiting for network configuration, and selects any one of the smart devices in a state of waiting for network configuration as the first smart device;

[0084] S123a: The user terminal extracts the new routing information of its own networking and configures it to the first smart device, and the first smart device connects to the network according to the new routing information.

[0085] like Figure 5 As shown, as another optional specific embodiment, in step S120, the method of configuring the new routing information to the first smart device and connecting to the network specifically includes:

[0086] S121b: Select any smart device in a state of waiting for network configuration as the first smart device;

[0087] S122b: The first smart device receives the input new routing information and connects to the network.

[0088] like Figure 6 As shown, as a specific embodiment, in step S130, the method of updating the routing information of the first smart device in the routing configuration information table to the new routing information specifically includes:

[0089] S131: Acquire the new routing information through a DHCP server;

[0090] S132: Package the first smart device's unique device identification code and the new routing information into a structured data format; in this embodiment, the structured data format is a json structured data format, specifically in the format of {"gateway":"192.168.1.1","ssid":"wifiwifiwifi","password":"12345678"}.

[0091] S133: Publishing the packaged data format to a specified MQTT topic server through the MQTT protocol;

[0092] S134: The cloud server subscribes to the corresponding topic of the MQTT topic server and parses the data format therein:

[0093] S135: Update the routing information of the corresponding smart device in the routing configuration information table according to the parsed device unique identification code and the new routing information.

[0094] like Figure 7 As shown, as a specific embodiment, step S140 specifically includes:

[0095] S141: when updating the original routing information of the first smart device in the routing configuration information table to the new routing information, recording the original routing information of the first smart device;

[0096] S142: Searching the routing configuration information table for a smart device whose routing information is consistent with the original routing information of the first smart device and using the smart device as the other smart device;

[0097] S143: The cloud server directly sends the new routing information to each of the other smart devices via the MQTT topic server through the MQTT protocol.

[0098] In addition, in step S150, when each of the other smart devices receives the new routing information, it can directly connect to the network according to the new routing information; specifically, through the automatic networking unit set in the communication control module of each smart device, when the automatic networking unit receives the new routing information sent by the cloud server, it automatically connects to the network according to the new routing information. Alternatively, in step S150, when each of the other smart devices receives the new routing information, a prompt message is first generated, and the prompt message displays the new routing information and provides an option of whether to connect to the network. After each of the other smart devices receives the indication of confirming the connection, it connects to the network according to the new routing information.

[0099] As a preferred embodiment, the routing configuration information table also includes device networking status information of each smart device. The format of the optimized routing configuration information table is as shown in Table 5 below:

[0100]

[0101] Table 5

[0102] Based on the above-mentioned optimized routing configuration information table, the multi-device networking method also includes: the cloud server monitors the networking status of each smart device in real time and updates the device networking status information, and the device networking status information includes the connected status and the disconnected status; in addition, in S140, when the cloud server searches for other smart devices with the same original routing information as the first smart device in the routing configuration information table, the smart devices whose device networking status information is that they are already connected to the network are eliminated.

[0103] The specific means of monitoring the networking status of each smart device is: a keep-alive mechanism is set between the smart device and the cloud server. This embodiment uses the keep-alive time interval included in the MQTT protocol. The smart device must send at least one message (including a PINGREQ message) to the cloud server within the time interval. If the cloud server does not receive any message within the keep-alive time, it will be considered that the smart device has been disconnected.

[0104] As a more preferred embodiment, the routing configuration information table also includes the type information of each smart device, the model information of each smart device, the binding status information of each smart device, the binding time of each smart device, the recorded error information, the last communication time between each smart device and the cloud server, the firmware version information of each smart device, etc. The format of the further optimized routing configuration information table is as follows in Table 6:

[0105]

[0106] Table 6

[0107] In a multi-device networking method and system provided by the present invention, the cloud server not only manages the binding information of the user terminal and multiple smart devices, but can also timely and automatically manage and update the network configuration information on the cloud server; moreover, when other smart devices with the same original routing information as the first smart device are connected to the network in batches, they can connect to the network by themselves without the need to operate through the user terminal. The present invention can greatly improve the efficiency of multi-device networking and the management efficiency of networking configuration information in the scenario of routing information update.

[0108] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
