Optionally, the device networking system 10 may include a plurality of terminals 101 and a plurality of smart home devices 102, and fig. 1 illustrates only one terminal 101 and three smart home devices 102 as an example. Illustratively, the terminal 101 may include a mobile phone, a tablet computer, a notebook computer, and other terminals having wireless transceiving functions and further interacting with a user. The smart home device 102 may include various household appliances, such as a switch, a refrigerator, a television, a washing machine, an air conditioner, a humidifier, an electric lamp, and the like.
Fig. 2 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, where the electronic device may be the terminal 101 or the smart home device 102, and fig. 2 takes the electronic device as the smart home device 102 as an example. As shown in fig. 2, the electronic device may include a Near Field Communication (NFC) module 1021, a wireless Communication module 1022, and a controller 1023.
The NFC module 1021 operates based on NFC technology, which is a short-range high-frequency radio technology with a communication distance of within 20 centimeters, for example within 10 centimeters, at an operating frequency of 13.56MHz (megahertz). The data transmission speed of the NFC module may be 106 kbit/s, 212 kbit/s, or 424 kbit/s.

The wireless communication module 1022 may now include a zigbee unit. Optionally, the smart home device may also use other protocols to perform communication, for example, the wireless communication module 1022 may also include a bluetooth unit, and may also include a wireless fidelity (Wi-Fi) unit, and the zigbee unit, the bluetooth unit, and the Wi-Fi unit may be integrated on the same chip. The controller 1023 may include a Micro-controller Unit (MCU), and the wireless communication module 1022 and the controller 1023 may be integrated on the same chip.

The coil 1024 may be located at a side of the NFC module 1021 facing the outside of the smart home device 102. When the coil 1024 is in a magnetic field (e.g., an alternating magnetic field, i.e., a radio frequency field), it can be charged by the alternating magnetic field, and the voltage of the coil 1024 increases during charging. The amplifying circuit 1025 may amplify the voltage on the coil 1024 and transmit the amplified voltage to the controller 1023.
It should be noted that before the NFC module in the smart home device 102 interacts with another NFC module (e.g., the NFC module in the terminal 101), the other NFC module needs to send out a magnetic field first to charge the NFC module in the smart home device 102. The NFC module in the smart home device 102 can send information to the other NFC module. Since the coil 1024 is located on the side of the NFC module 1021 facing the outside of the smart home device 102, when the NFC module 1021 is charged under the action of the terminal 101, the coil 1024 is located in front of the terminal and the NFC module 1021, and the coil 1024 may also be charged under the action of the terminal. In this embodiment, the controller 1023 in the smart home device 102 may determine the operating state of the NFC module 1021 through the coil 1024 and the voltage amplifying circuit 1025, that is, determine whether another NFC module interacts with an NFC module in the smart home device 102.

The method may be applied to the smart home device 102 shown in any one of fig. 1 to 3, where the smart home device includes an NFC module, a wireless communication module, and a controller, and the method may be specifically applied to the controller in the smart home device.

The NFC module in the terminal can send a magnetic field to the NFC module in the smart home device, the NFC module in the smart home device can be charged under the action of the magnetic field, and then the device information of the smart home device can be sent to the NFC module in the terminal. Optionally, the device information of the smart home device may be stored in the NFC module. Optionally, the smart home device may further include a memory, and the device information of the smart home device may be stored in the memory. The NFC module may obtain the device information from the memory and send the device information to the NFC module of the terminal.
After the controller in the intelligent household equipment determines that the NFC module sends the equipment information, the controller can control the intelligent household equipment to enter a network access state. Furthermore, the wireless communication module in the smart home device can be controlled to send a network access request to the gateway to be accessed, wherein the network access request carries the identifier of the wireless communication module. Optionally, the wireless communication module may send the network access request in a broadcast manner, and the gateway may monitor broadcast information in an area where the gateway is located to receive the network access request. Alternatively, the wireless communication module may send the network access request only to the gateway to be accessed point to point.
And step 403, receiving, by the wireless communication module, a target key sent by the gateway based on the device information and the network access request.
Illustratively, the target key may be a communication key of the gateway, such as a password (password) of the gateway. The target key may also be other information obtained by processing the communication key, and the embodiment of the present application is not limited. Each gateway has its own specific communication key based on which it can connect to the gateway for information interaction with the gateway. The communication KEY may also be NWK KEY.
After the wireless communication module of the intelligent household equipment receives the target key sent by the gateway, the controller can control the wireless communication module to establish connection with the gateway based on the target key so as to realize network access of the intelligent household equipment.

The intelligent home equipment can send equipment information to the NFC module of the terminal through the NFC module, and then the wireless communication module of the intelligent home equipment can receive a target key sent by the gateway so as to connect the gateway based on the target key. Therefore, the user only needs to enable the terminal to be close to the intelligent household equipment, if the terminal is close to the NFC module of the intelligent household equipment, the terminal can automatically access the network.

After the intelligent home equipment sends the equipment information, the intelligent home equipment can enter a network access state to send a network access request to the gateway. The gateway allows the intelligent household equipment to access the network based on the equipment information and the network access request, and further sends a target key to the intelligent household equipment so that the intelligent household equipment can establish connection with the gateway based on the target key. Therefore, the device information of the intelligent household equipment does not need to be manually input on the terminal by a user, the process of acquiring the device information by the gateway is simplified, and the network access effect of the intelligent household equipment is improved.

and step 501, receiving the device information of the intelligent household device sent by the terminal.
The gateway includes a wireless communication module and a controller. Illustratively, the gateway 103 may receive the device information of the smart home device, which is sent by the wireless communication module of the terminal, through the wireless communication module thereof.
The gateway can also receive a network access request broadcasted by the intelligent household equipment through the wireless communication module. After receiving a network access request sent by any device, the gateway may determine whether device information of the device sent by the terminal is received. After determining to receive the device information of the device, the gateway can learn that the device determines to access the gateway, and further can send a target key to the device. For the target key, please refer to the related description of step 403, and the description of the embodiments of the present application is omitted.
The gateway can wait for the smart home device to establish communication connection with the gateway based on the target key sent by the smart home device. And when the intelligent household equipment is determined to establish communication connection with the gateway based on the communication key, the gateway realizes the establishment of the connection with the intelligent household equipment.
To sum up, in the device networking method provided by the embodiment of the application, the smart home device may send the device information to the terminal through the NFC module, and then the terminal may send the device information to the gateway. After the intelligent home equipment sends the equipment information, the intelligent home equipment can enter a network access state to send a network access request to the gateway. The gateway allows the intelligent household equipment to access the network based on the equipment information and the network access request, and further sends a target key to the intelligent household equipment so that the intelligent household equipment can establish connection with the gateway based on the target key. Therefore, the device information of the intelligent household equipment does not need to be manually input on the terminal by a user, the process of acquiring the device information by the gateway is simplified, and the network access effect of the intelligent household equipment is improved.
Fig. 6 is a flowchart of a further device network access method according to an embodiment of the present application. The method may be used for the terminal 101 in fig. 1, and the terminal 101 may include an NFC module, a wireless communication module, and a controller, and the method may be particularly used for the controller in the terminal 101. As shown in fig. 6, the method may include:
To sum up, in the device networking method provided by the embodiment of the application, the terminal can acquire the device information of the smart home device through the NFC module, and then can send the device information to the gateway. After the intelligent home equipment sends the equipment information, the intelligent home equipment can enter a network access state to send a network access request. The gateway allows the intelligent household equipment to access the network based on the equipment information and the network access request, and further sends a target key to the intelligent household equipment so that the intelligent household equipment can establish connection with the gateway based on the target key. Therefore, the device information of the intelligent household equipment does not need to be manually input on the terminal by a user, the process of acquiring the device information by the gateway is simplified, and the network access effect of the intelligent household equipment is improved.
Fig. 7 is a flowchart of another device networking method according to an embodiment of the present application. The method can be used for the equipment network access system shown in figure 1. As shown in fig. 7, the method may include:
and 701, establishing NFC connection between the terminal and the intelligent household equipment.
The terminal and the intelligent home equipment establish NFC connection, namely the NFC module of the terminal and the NFC module of the intelligent home equipment establish connection. The user can operate to the terminal to control the NFC module in the terminal to start work, and then establish connection with the NFC module in the intelligent household equipment.
Optionally, an Application (APP) related to smart home may be installed in the terminal. The user can control the terminal to start the application program, and then the terminal is controlled based on the application program so as to control the NFC module in the terminal to start working. Illustratively, fig. 8 is a schematic diagram of an operation process of a terminal provided in an embodiment of the present application. As shown in fig. 8, icons of respective applications installed in the terminal may be displayed on the user's home interface M1. The user may first click the icon Z of the smart home application displayed on the main interface M1 of the terminal, and trigger the terminal to start the application. After the application program is started, the terminal can display an interface M2, and icons of various smart home devices in the home environment, such as icons of smart home devices in a gateway, a television, a washing machine, a refrigerator, an air conditioner and the like, can be displayed in the interface M2. Next, the user may click on an icon of the gateway to trigger the terminal to display an interface M3, in which relevant operation options available for the gateway may be displayed in the interface M3. For example, the operation options for the gateway may include an option to open the NFC module, and the user may click on the option to trigger the NFC module in the terminal to start working.
Because the communication distance of the NFC module is smaller than the distance threshold, if the distance threshold is 10 centimeters, the terminal and the smart home device may establish the NFC connection only when the distance between the terminal and the smart home device is smaller than the distance threshold. After the user starts the work of controlling the NFC module of the terminal, the user may bring the terminal close to the smart home device to be networked, for example, close to or in contact with an area where the NFC module of the smart home device is located. The NFC module of the terminal can send out an alternating magnetic field after starting up. When the NFC module of the smart home device is located in the alternating magnetic field, the NFC module can be charged under the action of the alternating magnetic field. The NFC module of the intelligent household equipment can be connected with the NFC module of the terminal after being charged. After the NFC module starts to operate, for example, after entering the peer-to-peer mode, the NFC module may perform device search to search whether there are other NFC modules in an area of a target range around the NFC module. For example, after the NFC module of the smart home device is charged, the NFC module of the terminal may be detected, and then an NFC connection may be established with the other NFC module.
For the device information of the smart home device, reference may be made to related descriptions in step 401 in fig. 4, which is not described again in this embodiment of the present application. After the NFC connection is established between the intelligent household equipment and the terminal, the equipment information stored in the intelligent household equipment can be sent to the terminal through the NFC connection, and the NFC module of the terminal can receive the equipment information. Optionally, the device information sent by the smart home device is coded information, and the terminal may analyze the information sent by the smart home device after receiving the information, so as to obtain real device information. For example, the terminal can analyze the received information to obtain the installation code of the intelligent household equipment. Different installation codes of different intelligent household devices are different, and a network access Key (Link Key) adopted when the intelligent household devices access to the network can be determined based on the installation codes.
Correspondingly, in step 702, the terminal receives the device information sent by the smart home device. Optionally, after the terminal finishes receiving the device information, the terminal may display a prompt message indicating that the device information is completely sent. Fig. 9 is a schematic view of a usage scenario of a terminal provided in an embodiment of the present application, and as shown in fig. 9, after acquiring device information of an intelligent switch, the terminal may display a prompt message that "the device information has been successfully acquired". The user can know that the terminal has acquired the equipment information of the intelligent household equipment based on the prompt information, and then can move the terminal away from the vicinity of the intelligent household equipment.
It should be noted that, in the related art, the same installation code is used as the network access key for different smart home devices. If the smart home device is a Zigbee device, a universal Zigbee Alliance (english: Alliance)09 is adopted as a network access key for each Zigbee device in the related technology. Therefore, other devices except the gateway can know the network access key of the intelligent home equipment, and the interaction process between the gateway and each intelligent home equipment can be monitored, so that the safety of information interaction is low. In the embodiment of the application, each intelligent household device has an independent installation code, and the independent network access key of each intelligent household device is determined based on the installation code. And then the information interaction safety of the gateway and each intelligent household device can be improved.
And 703, the terminal sends the equipment information of the intelligent household equipment to the gateway.
After the terminal acquires the device information of the smart home device, the device information can be sent to the gateway. Accordingly, the gateway can receive the device information transmitted by the terminal. For example, the device information sent by the terminal to the gateway is the device information obtained after the terminal analyzes the device information. Optionally, the terminal may send all information in the device information to the gateway, or may send only part of information in the device information to the gateway, where the device information sent to the gateway at least includes an identifier and an installation code of the smart home device. For example, the terminal may be communicatively connected to the gateway, and may directly transmit the device information to the gateway. Optionally, the terminal and the gateway may both be connected to the cloud platform. At this time, the terminal can send the device information to the cloud platform, so that the cloud platform sends the device information to the gateway through the ethernet.
After receiving the device information sent by the terminal, the gateway can determine that the smart home devices need to access the network, and can determine that the smart home devices indicated by the device information need to access the gateway. Furthermore, the gateway can enter a network access permission state, and only the intelligent household equipment indicated by the equipment information is permitted to access the network. For a certain intelligent home device, if the gateway does not receive the device information of the intelligent home device, even if the gateway receives the network access request sent by the intelligent home device, the gateway can refuse the intelligent home device to access the gateway.
It should be noted that, in the related art, the gateway has a start button for starting the network access state. When the intelligent household equipment needs to be accessed to the network, the user needs to manually start the starting button, and then the gateway can enter the network access allowing mode. In the embodiment of the application, the gateway can directly enter the network access permission state after receiving the device information sent by the terminal, and a user does not need to perform other operations on the gateway, so that the network access process of the intelligent home device is simplified.
Step 703 may be performed by a wireless communication module in the terminal. Accordingly, the wireless communication module in the gateway may receive the device information.
After receiving the device information of any intelligent device sent by the terminal, the gateway may encrypt a communication key of the gateway based on the device information. In the embodiment of the present application, a communication key encrypted based on device information is referred to as a target key. Optionally, the gateway may also generate a network access key of the smart home device through the installation code in the device information, and further encrypt a communication key of the gateway based on the network access key to obtain a target key. Optionally, the gateway may store the target key after generating the target key. And the gateway can also store the corresponding relation between the target key and the intelligent household equipment so as to mark the intelligent household equipment corresponding to the target key. Step 704 may be performed by a controller in the gateway.
Optionally, the gateway encrypts the communication key with the device information or the network access key as a password. If the device information or the network access key is used as a password, the communication key is encoded through an AES-MMO hash function, and a communication key in a ciphertext form, namely a target key, is obtained.
It should be noted that, in the embodiment of the present application, the communication key of the gateway is encrypted based on the unique device information of each smart home device, so that only the device that knows the device information of the smart home device can successfully decrypt the target key, so as to obtain the real communication key of the gateway. Therefore, only the intelligent home equipment can obtain the real communication key of the gateway based on the target key, so that other malicious equipment can be prevented from obtaining the communication key of the gateway and further being connected with the gateway, and the information interaction safety and the equipment network access safety of the gateway are improved.
After the smart home device sends the device information to the terminal through the NFC module in step 702, the smart home device may enter a network access state. Furthermore, the intelligent household equipment can broadcast the network access request through the wireless communication module. The gateway in the broadcast range of the network access request can receive the network access request, namely the intelligent home equipment sends the network access request to the gateway. The process of broadcasting the network access request by the smart home device may also be a process of scanning beacons (english: Beacon) of each channel within the range of the smart home device. Optionally, the smart home device may also obtain information of the gateway, so as to send the network access request to the gateway only in a point-to-point manner. For example, the information of the gateway can be sent to the NFC module of the smart home device by the terminal through the NFC module.
Optionally, the controller in the smart home device may detect whether the NFC module sends the device information to the terminal through the coil and the voltage amplifying circuit. After the NFC module is determined to send the device information to the terminal, the intelligent household device is controlled to enter a network access state, and the wireless communication module is controlled to send a network access request. After the terminal is close to the intelligent home equipment, the NFC module in the intelligent home equipment can be charged under the action of an alternating magnetic field emitted by the terminal. The coil in this in-process intelligent household equipment is located between this NFC module and the terminal, so when charging to the NFC module, this coil also can charge. The coil is connected to a voltage amplification circuit that amplifies the voltage across the coil to a range recognizable by the controller, such as 3 volts to 5 volts. After the controller receives the voltage output by the voltage amplifying circuit, the controller can determine that the NFC module sends the equipment information to the terminal, and then the intelligent household equipment can be controlled to enter a network access state. Through setting up voltage amplifier circuit, can also prevent to beat the circumstances such as thunder and make the coil charge, lead to the controller mistake and think the circumstances of entering the network entry state.
It should be noted that, in the related art, the smart home device has a start button in the network access state. When the intelligent home equipment needs to be accessed to the network, the user needs to manually start the starting button, and then the intelligent home equipment can send an access request to the gateway. In the embodiment of the application, after the terminal acquires the device information from the smart home device, the smart home device may monitor the device information sending operation of the NFC module through the coil and the voltage amplifying circuit. The smart home equipment directly enters the network access state after the NFC module is monitored to send the equipment information, the user does not need to perform other operations on the smart home equipment, and the network access process of the smart home equipment is simplified.
Step 705 is executed by a wireless communication module in the smart home device. Accordingly, the wireless communication module in the gateway may receive the network entry request.
Step 706, when it is determined that the network access request is sent by the smart home device indicated by the received device information, the gateway sends the target key corresponding to the smart home device.
After receiving any network access request, the gateway can determine whether the sending device of the network access request is a device that the gateway allows to access the network. For example, the gateway may determine whether the device information is sent by the smart home device indicated by the received device information, that is, whether the device information of the smart home device sent by the terminal is received. And if the equipment information of the intelligent household equipment is received, allowing the intelligent household equipment to access the network and responding to the network access request. If the corresponding target key is sent to the smart home device, that is, the communication key of the gateway encrypted based on the device information of the smart home device is used for the smart home device to access the gateway based on the target key. Correspondingly, the intelligent home equipment receives the target key sent by the gateway. And if the gateway determines that the equipment information of the intelligent household equipment is not received, prohibiting the intelligent household equipment from accessing the network, and ignoring the network access request.
It should be noted that, in the related art, for a sending device of a received network access request, a gateway allows the sending device to access the gateway. However, since the first gateway is closer to the second gateway, the second gateway also receives the network access request sent by the sending device, and the sending device may access the second gateway. In the embodiment of the application, the gateway only allows the intelligent home devices indicated by the received device information to access, so that the network access accuracy of the intelligent home devices can be ensured, and the network access effect of the intelligent home devices is improved.
In step 706, determining whether the network access request is sent by the smart home device indicated by the received device information may be executed by a controller in the gateway; the process of sending the target key to the smart home device may be performed by a wireless communication module in the gateway. Accordingly, the wireless communication module in the smart home device may receive the target key.
And 707, the smart home device decrypts the received target key based on the device information.
After receiving the target key, the smart home device may decrypt the target key based on the device information of the smart home device to obtain a real communication key. Optionally, if the gateway encrypts the communication key of the gateway through the network access key of the smart home device, after receiving the target key, the smart home device may also generate the network access key based on the installation code of the smart home device, and further decrypt the target key based on the network access key. It should be noted that step 707 may be executed by a controller in the smart home device.
Step 708, after the smart home device successfully decrypts the received target key, establishing a connection with the gateway based on the decrypted communication key.
After the intelligent home equipment successfully decrypts the received target key, the real communication key of the gateway can be obtained. And then the intelligent household equipment can successfully establish connection with the gateway based on the communication key. Correspondingly, the gateway also establishes connection with the intelligent household equipment based on the communication key. At this moment, the smart home device successfully accesses the network. Step 708 may be performed by a wireless communication module of the smart home device, and accordingly, the wireless communication module in the gateway is connected to the wireless communication module of the smart home device.
It should be noted that, in the embodiment of the present application, for each target key, since the target key is obtained by encrypting based on the device information of the corresponding smart home device, the target key can be successfully decrypted only by knowing the device information. Therefore, the intelligent household equipment can be ensured to successfully decrypt the received target key to obtain the communication key of the gateway, and then the communication key is normally connected with the gateway, other equipment is prevented from acquiring the communication key of the gateway, and the network access safety of the intelligent household equipment is ensured.
And 709, the intelligent household equipment sends the feedback information of successful decryption to the gateway through the connection.
After the connection between the intelligent household equipment and the gateway is successfully established, feedback information of successful decryption can be sent to the gateway. Step 709 may be executed by the wireless communication module of the smart home device, and accordingly, the wireless communication module in the gateway may receive the feedback information.
And step 710, the gateway sends a prompt message that the intelligent household equipment has successfully accessed the network to the terminal based on the feedback information.
After receiving the feedback information sent by the intelligent home equipment, the gateway can send prompt information that the intelligent home equipment has successfully accessed the network to the terminal so as to inform the user that the intelligent home equipment has successfully accessed the network. Step 710 may be performed by the wireless communication module of the gateway, and accordingly, the wireless communication module in the terminal may receive the prompt message.
And 711, displaying a prompt message that the intelligent household equipment has successfully accessed the network by the terminal.
The terminal may further include a display screen. After receiving the prompt message, the terminal can display the prompt message through the display screen to inform a user that the intelligent home equipment has successfully accessed to the network, and the intelligent home equipment has joined the family group where the gateway is located and is interconnected with the equipment in the group. And then, the user can intelligently control the intelligent household equipment through the terminal.
Illustratively, fig. 10 is a schematic diagram of an operation flow of another terminal provided in an embodiment of the present application. The display interface may display a prompt message that the intelligent switch has successfully accessed the network, and the prompt message may be "whether the intelligent switch has successfully accessed the network and is currently controlled".
