technical field

The present application relates to the field of control, and in particular, to a network repair method, an electronic device and a mobile device.

Background technique

The rapid development of the Internet of Things (IoT) has enabled many IoT devices in many fields, such as industrial production, smart home, disaster prevention monitoring, and logistics tracking, to be connected to the network. A mobile device communicates with other devices in the network through the routing device to which it is connected. However, most IoT devices cannot directly interact with the mobile device held by the user, and need to route the device to interact with the mobile device. After the IoT device is connected to the routing device through the distribution network, the user controls the IoT device through the mobile device.

In some cases, such as the routing device ID or the routing device's access password is modified, the mobile device cannot control the IoT device. The IoT device needs to enter the network distribution mode. After the network is connected to the routing device again, the mobile device can control the IoT device again. In this way, the user operation is more complicated. In addition, some IoT devices will be reset to factory settings after entering the network configuration mode, which will result in the loss of previously saved data on the IoT device. In this way, it is also not conducive to the subsequent operation of the IoT device by the mobile device.

SUMMARY OF THE INVENTION

Therefore, in a situation such as the routing device identification or the routing device's access password is modified, how to automatically and quickly access the routing device for IoT devices is a problem that we need to solve.

In order to solve the above technical problems, the present application proposes a network repair method, electronic device and mobile device, so that after the routing device identifier or the access password of the routing device is modified, the IoT device can automatically and quickly access the routing device without the need for User operation, without losing previously saved data.

In a first aspect, a network repair method is provided, which is applied to an electronic device. The electronic device is disconnected from a routing device. The electronic device includes: a processor; a memory; and a first antenna, where the transmission distance of the first antenna is a first distance , the first distance is greater than the preset safety distance; the second antenna, the transmission distance of the second antenna is the second distance, and the second distance is less than or equal to the preset safety distance; wherein, the first antenna and the second antenna are different an antenna; the method includes: reconnecting the routing device using the first distribution network parameters of the routing device through the first antenna; after the reconnection of the routing device fails, periodically sending a first request message through the second antenna; the first request The message includes the session key; the first response message of the mobile device connected to the routing device is received; the first response message includes the encrypted second configuration network parameter; in response to the first response message, the encrypted second The network distribution parameters are obtained, and the second distribution network parameters are obtained; and the second distribution network parameters are used to connect to the routing device through the first antenna. The first network configuration parameter includes a first device identifier and a first access password of the routing device; the second network configuration parameter includes a second device identifier and a second access password of the routing device.

In this method, due to the modification of the device identification or access password of the routing device, the IoT device is disconnected from the routing device, and the automatic reconnection of the routing device fails. The IoT device requests the mobile device to send the new configuration network parameters of the routing device to it through the weak antenna (the weak antenna and the strong antenna are different antennas). The IoT device also sends a session key to the mobile device, which is used by the mobile device to encrypt new configuration parameters. Since the transmission distance of the weak antenna is less than or equal to the preset safe transmission distance, only the mobile device within the safe distance can receive the session key, which can ensure data security. After the IoT device receives the new configuration parameters from the mobile device, it uses the new configuration parameters to connect to the routing device. In this way, after the routing device ID or the routing device's access password is modified, the IoT device can automatically and quickly access the routing device without user operation or loss of previously saved data.

Since the transmission distance of the weak antenna is less than or equal to the preset safe transmission distance, only the mobile device within the safe distance can receive the session key, which can ensure data security. After the IoT device receives the new configuration parameters from the mobile device, it uses the new configuration parameters to connect to the routing device.

The mobile device 110 can search for the SSID of the IoT device 130 through the IoT APP, and the mobile device 110 accesses the SSID of the IoT device 130 to establish communication with the IoT device 130. After that, on the IoT APP of the mobile device 110, the user needs to click the relevant button and input the SSID and access password of the routing device 120. Mobile device 110 sends the SSID and access password of routing device 120 to IoT device 130 . The above-mentioned sending of the SSID and the access password of the routing device 120 may be sent after encryption. In some embodiments, mobile device 110 (IoT APP on mobile device 110) and IoT device 130 exchange respective identity credentials with each other. Exemplarily, the mobile device 110 and the IoT device 130 respectively generate their own public and private key pairs, and the mobile device 110 (the IoT APP on the mobile device 110) and the IoT device 130 send their own public keys to the other party, and save the other party's public key. After receiving the SSID and access password of the routing device 120 sent by the mobile device 110, the IoT device 130 switches its Wi-Fi module to the station state, and uses the SSID and access password of the routing device 120 to access Routing device 120. At this time, as shown in FIG. 2B , the IoT device 130 is connected to the routing device 120 , and the mobile device 110 disconnects the Wi-Fi connection with the IoT device 130 . Next, the mobile device 110 automatically searches for the SSID of the Wi-Fi of the routing device 120, and uses the previously saved access password to access the routing device 120, as shown in FIG. 2C .

The IoT device 130 may be newly purchased by the user, or may be moved by the user from another place to connect to the routing device 120 . For example, the user lives in a villa with two floors. There is one routing device upstairs and one downstairs. The user moves the IoT device 130 upstairs to the downstairs for connecting the routing device 120 downstairs.

Alternatively, in FIG. 2A, the IoT device 130 and the mobile device 110 may also establish communication via Bluetooth. That is, the mobile device 110 sends the previously saved SSID and access password of the routing device 120 to the IoT device 130 through Bluetooth.

Alternatively, the above-mentioned Bluetooth communication can also be replaced by other short-range communication methods. It will not be expanded here.

Alternatively, the above-mentioned SSID can also be replaced with other identifiers. As long as each device can locate the corresponding device through the identifier.

As shown in FIG. 3A , after the IoT device 130 is connected to the routing device 120 , the IoT device 130 communicates with the routing device 120 normally. For example, the IoT device 130 receives the control message sent by the mobile device 110 through the routing device 120, and executes the corresponding function. After that, if at least one of the device identification (eg, SSID) and the access password of the routing device 120 is modified, the IoT device 130 will be disconnected from the routing device 120, as shown in FIG. 3B . The IoT device 130 is still unable to re-connect to the routing device 120 after many attempts. At this time, it is usually necessary to manually reset the IoT device 130 to make it re-enter the network distribution mode, and perform the network distribution process of FIG. 2A-FIG. 2B again. For example, there is a physical button on the IoT device 130, and the IoT device 130 can enter the network configuration mode by pressing the physical button. In this way, the user also needs to re-enter the relevant information (such as the SSID and access password of the routing device 120) on the IoT APP, and click the relevant button again, which is cumbersome to operate and has a poor user experience. In addition, some manufacturers' IoT devices will automatically restore the factory settings after pressing the above physical buttons and before entering the network configuration mode. That is, for IoT devices of some manufacturers, after pressing the above physical buttons, the factory settings are automatically restored, and then the network configuration mode is entered. In this way, the data previously saved by the IoT device (such as some memory data closely related to the user) will be lost, causing inconvenience to the user. For example, the IoT lock was previously set to automatically unlock when the mobile device of the male owner approaches from the outside to the inside, and make a sound of "Dad is back"; the IoT lock was also set to automatically unlock when the mobile device of the female owner approaches from the outside to the inside. Open the lock and make a sound of "Mom is back". In the above situation, since the IoT lock is restored to factory settings, the user needs to set the relevant parameters again, which brings inconvenience to the user.

An embodiment of the present application provides a network repair method for an IoT device. After at least one of an identifier of a routing device and an access password is modified, causing the IoT device to disconnect from the routing device, the IoT device is automatically connected to the routing device. . The method does not require user operation, nor does it need to restore the IoT device to factory settings, so that the IoT device can be automatically and quickly connected to the routing device.

In one example, FIG. 5A shows a structure of the above IoT device. As shown in FIG. 5A , the IoT device 130 may include a processor 131 , a wireless communication module 135 , an antenna 1 and an antenna 2 .

Among them, antenna 1 (such as a strong antenna) and antenna 2 (such as a weak antenna) are used for transmitting and receiving electromagnetic waves. Further, the wireless communication module 135 converts the electromagnetic wave received from the antenna 1 or the antenna 2 into a signal, and sends the signal to the processor 131 for processing; or the wireless communication module 135 receives the signal to be sent from the processor 131, via a strong antenna Or weak antennas turn into electromagnetic waves and radiate out. In the embodiment of the present application, the first transmission distance (such as 10 meters, 50 meters, etc., which can be set by the user) of the signal transmitted by the strong antenna is greater than the second transmission distance of the signal transmitted by the weak antenna (such as 0.2 meters, 0.3 meters, etc., specifically can be set by the user). The second transmission distance of the weak antenna transmission signal is less than or equal to the preset safe transmission distance; wherein, the safe transmission distance is the safe distance for the owner of the IoT device 130 to exchange secret information with the IoT device 130 through the mobile device. For example, the safe transmission distance can be The default settings are 100cm, 50cm, 30cm, 20cm, etc., so that the owner of the IoT device 130 can receive the secret information sent by the IoT device 130 at a distance of up to 100cm, so as to avoid unsafe behaviors (such as stealing routing device access) password), to ensure network security and other aspects of security. In some embodiments, the processor 131 may control the switching of strong antennas and weak antennas. When the IoT device 130 adopts a strong antenna, the mobile device receives the signal sent by the IoT device 130 only when the distance between the mobile device and the IoT device 130 is less than the first transmission distance; when the IoT device 130 adopts a weak antenna, The mobile device receives the signal sent by the IoT device 130 only when the distance between the mobile device and the IoT device 130 is smaller than the second transmission distance. The first transmission distance and the second transmission distance may be referred to as a first distance and a second distance, respectively.

In another example, FIG. 5B shows another structure of the above IoT device. As shown in FIG. 5B , the IoT device 130 may include a processor 131 , a wireless communication module 135 and an antenna 1 .

Exemplarily, when the resistance value of the variable impedance circuit module 1352 is the first resistance value, the transmission power of the antenna 1 is the second transmission power, and the distance for transmitting the wireless signal is the first transmission distance (to realize the function of a strong antenna); When the resistance value of the variable impedance circuit module 1352 is the second resistance value, the transmission power of the antenna 1 is the first transmission power, and the distance for transmitting wireless signals is the second transmission distance (to realize the function of a weak antenna). Wherein, the first transmission power is less than the second transmission power; the first transmission distance is greater than the second transmission distance, and the second transmission distance is less than or equal to the preset safe transmission distance. The first transmission distance and the second transmission distance may be referred to as a first distance and a second distance, respectively.

It can be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on IoT devices. In other embodiments of the present application, the IoT device may include more or less components than shown, or some components may be combined, or some components may be split, or different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

In some embodiments, the above-mentioned strong antenna and weak antenna may share a part of the wiring, for example, as described in the embodiments shown in FIGS. 6A-6C .

Illustratively, Figures 6A-6C illustrate three implementations of the weak antenna in Figure 5A. As shown in FIG. 6A-FIG. 6C, the strong antenna and the weak antenna may share a part of the wiring.

The strong antenna and the weak antenna in the IoT device in the embodiment of the present application can be switched by a radio frequency switch. Physically, both the weak antenna and the radio frequency switch (the weak antenna shown in the dashed box in FIG. 6A-FIG. 6C ) can be placed in the shielding case or the weak antenna can be placed in the chip.

The purpose of the weak antenna in the embodiment of the present application is to reduce the transmission distance as much as possible. The principle of constructing a weak antenna can be:

(1) Reduce the length of the antenna, thereby reducing the electromagnetic waves radiated into the air;

(2) Reduce the radiation efficiency, and convert a part of the electromagnetic wave radiation into heat energy and consume it through the resistance;

(3) Reduce the return loss, reflect part of the radio frequency energy back into the chip, etc.

The specific implementation of weak antenna can be used:

(i) shorten the antenna;

(ii) disconnect a point in the true antenna path, or at that point through a resistor, inductor, or capacitor to ground;

(iii) Use a shielding case or the like.

It should be understood that the specific implementation (i) and (ii) of the above weak antenna may be implemented on a PCB board or inside a chip.

It should also be understood that the function of the above-mentioned shielding cover is to cut off the path from the electromagnetic wave radiated by the antenna to the receiver, so as to achieve the purpose of weakening the radiation.

It should also be understood that the above-mentioned shortening of the antenna means that the weak antenna is shorter than the strong antenna. The structures of the three weak antennas are shown in FIGS. 6A to 6C , and the weak antennas are shown as the structures in the dotted boxes in FIGS. 6A to 6C . The structures of the strong antennas shown in FIGS. 6A to 6C are connected to a filter circuit (eg, a π-type circuit), a matching circuit (eg, a π-type circuit) and a matching circuit through radio frequency input/output (RFIO) pins. External antenna body (eg, the antenna body may be a length of metal trace). The weak antenna a shown in the dashed box in FIG. 6A , the weak antenna b shown in the dashed box in FIG. 6B , and the weak antenna c shown in the dashed box in FIG. 6C have different lengths, but are shorter than the strong antennas. The function of the filter circuit is to prevent interference, and the matching circuit is used to match the strong antenna.

Exemplarily, as shown in FIG. 6A , the weak antenna a may be located in the shield. Wherein, the weak antenna a may include the RFIO pin of the Wi-Fi chip in the shield and the first switch of the 2 switches (the first switch is not connected to any device). Sometimes, the weak antenna a may also include a trace between the RFIO pin and the first switch. Among them, the 2-way switch refers to the switch between the trace or RFIO pin and the filter circuit. Through the 2-way switch, the trace or RFIO pin can be connected or disconnected from the filter circuit. The first switch is the switch shown in FIG. 6A that is connected to the RFIO pin or trace and disconnected from the filter circuit. It should be understood that the 2-way switch in the embodiment of the present application may be a single-pole double-throw switch.

Exemplarily, as shown in FIG. 6B , the weak antenna b may be located in the shielding case. Wherein, the weak antenna b may include the RFIO pin of the Wi-Fi chip in the shield, the first switch of the 2-way switch (the first switch is connected to a resistor), and a matching device. Sometimes, the weak antenna b may also include a first trace between the RFIO pin and the first switch. Sometimes, the weak antenna b may also include a second trace between the matching device and the ground. The matching device can be a resistor. Part of the electromagnetic wave radiation can be converted into heat energy and consumed by grounding the resistance, thereby reducing the radiation efficiency of the weak antenna b. The 2-way switch refers to the switch between the RFIO pin or the first trace and the resistor and filter circuit. Through this switch, the RFIO pin or the first trace can be connected to the resistor and disconnected from the filter circuit. On, or the RFIO pin or the first trace can be disconnected from the resistor and connected to the filter circuit. The first switch is a switch connected to the matching device and disconnected from the filter circuit among the two switches.

Exemplarily, as shown in FIG. 6C , the weak antenna c may be located in the shield. Wherein, the filter circuit matched by the chip is followed by a matching device (for example, a resistor) to the ground. The weak antenna c may include the RFIO pin of the Wi-Fi chip in the shield, the filter circuit, the first switch of the 2-way switch (the first switch is connected to a resistor), and a matching device (eg, a resistor). Sometimes, the weak antenna c may also include a first trace between the RFIO pin and the filter circuit. Sometimes, the weak antenna c may further include a second trace between the filter circuit and the matching device. Part of the electromagnetic wave radiation can be converted into heat energy and consumed by grounding a matching device (for example, a resistor), thereby reducing the radiation efficiency of the weak antenna c. Wherein, the 2-way switch refers to the switch between the filter circuit inside the shield, the matching device, and the matching circuit outside the shield. Through the 2-way switch, the filter circuit in the shield can be connected to the matching device and disconnected from the matching circuit outside the shield; connected to the matching circuit. The first switch is a switch used to connect the filter circuit and the matching device in the shield.

It should be understood that the above-mentioned strong antennas in FIGS. 6A to 6B may include RFIO pins, the second switch among the 2-way switches, a filter circuit, a matching circuit, and an antenna body externally connected to the matching circuit. Sometimes, the strong antenna in FIGS. 6A to 6B may also include a trace between the RFIO pin and the second switch of the 2-way switches. The second switch is a switch used to connect the RFIO pin and the filter circuit.

The above-mentioned strong antenna in FIG. 6C may include an RFIO pin, a filter circuit, a second switch in the 2-way switch, a matching circuit, and an antenna body connected outside the matching circuit. Sometimes, the strong antenna in Figure 6C can also include traces between the RFIO pins and the filter circuit. The second switch is a switch used to connect the filter circuit inside the shield and the matching circuit outside the shield.

It should be understood that the wireless communication module 135 shown in FIG. 5A may be a Wi-Fi chip, or may be a Wi-Fi chip and its matching circuit. The wireless module 1351 shown in FIG. 5B may be a Wi-Fi chip, and the wireless communication module 135 shown in FIG. 5B may be a Wi-Fi chip and its matching circuit.

The above different weak antenna structures, together with the different transmit power (Tx power) settings of the Wi-Fi chip, can meet different ultra-short-range communication requirements (for example, from 10cm to 2m).

Exemplarily, Table 1 shows the communication distances of several different weak antenna structures with different transmit powers.

Table 1

Due to the characteristics of the physical device on the chip, the difference between the maximum transmit power and the minimum transmit power of the antenna is correlated. If the minimum transmit power of the electronic equipment is reduced very low, the maximum transmit power will also be reduced, so that the distance requirement during normal operation cannot be met. Since different electronic devices have different structures and different safety performance requirements for electronic devices, manufacturers of electronic devices can use different weak antenna structures and transmit powers to ensure the communication distance of electronic devices. Exemplarily, for different smart air conditioner manufacturers, the thickness of the smart air conditioner housing may be different, so under the condition of the same weak antenna structure and the same transmit power, the communication distance at which the smart air conditioner can be discovered may also be different. Different electronic equipment manufacturers can obtain the safe distance for electronic equipment to be discovered according to the structure of their electronic equipment, the structure of weak antennas and a certain transmission power, and combined with testing. The user can set the transmit power for the three weak antennas (weak antenna a, weak antenna b and weak antenna c) according to Table 1, and adjust the transmit power according to the test results, so that the weak antenna can reach the corresponding distance when transmitting.

Combining the above examples, take the first distance as 5 meters and the second distance as 0.3 meters as an example. When the IoT device adopts a strong antenna, if the distance between the IoT device and other devices (such as mobile devices) is less than the first distance (such as the mobile device is at position 1 as shown in Figure 7), the IoT device can communicate with other devices (such as mobile devices) device) communication; when the IoT device adopts a weak antenna, if the distance between the IoT device and other devices (such as mobile devices) is less than the second distance (such as other devices located at position 2 shown in Figure 7), the IoT device can communicate with other devices device (eg mobile device) communication.

The IoT device detects that it is disconnected from the routing device, and initiates the process of automatically reconnecting the routing device using the saved device ID and access password of the routing device. If the IoT device is disconnected from the routing device due to a short-term failure of the routing device, the IoT device can repair the network connection by automatically reconnecting the routing device. If the device ID of the routing device is modified, the access password of the routing device is modified, etc., because the network configuration parameters used by the IoT device remain unchanged when the routing device is automatically reconnected, the network cannot be repaired by automatically reconnecting the routing device. connect. The IoT device fails to automatically reconnect to the routing device m times.

After the IoT device is disconnected from the routing device, the mobile device cannot communicate with the IoT device through the routing device. The mobile device determines that the IoT device is offline.

In an example, as shown in FIG. 10 , the mobile device sends a first keep-alive request to the IoT device according to a first period (for example, 1s). After receiving the first keep-alive request, the IoT device sends a first keep-alive response to the mobile device. If the mobile device receives the first keep-alive response within a preset time period (for example, 10ms), it is determined that the IoT device is normally connected to the routing device (not offline). It can be understood that the mobile device sends the first keep-alive request to the IoT device through the routing device, and receives the first keep-alive response through the routing device. If the mobile device does not receive the first keep-alive response within a preset time period (for example, 10ms), it is determined that the IoT device is offline. Optionally, after the mobile device sends the first keep-alive request to the IoT device, if the first keep-alive response is not received within a preset time period (for example, 10 ms), the mobile device may send the first keep-alive request to the IoT device again. If the number of times the mobile device sends the first keep-alive request to the IoT device exceeds the preset number of times, and the first keep-alive response is not received, it is determined that the IoT device is offline.

In an implementation manner, the mobile device displays the first prompt information. The first prompt information is used to prompt the user to bring the mobile device close to the IoT device. Illustratively, taking a mobile phone as a mobile device as an example, as shown in FIG. 11 , the mobile device 110 displays a device management interface 1110 , and the device management interface 1110 includes operation information of the IoT device “smart desk lamp”. The mobile device detects that the smart desk lamp is not connected to the routing device, and displays the prompt message 1111 "Device is offline". In one example, the mobile device receives the user's click operation on the prompt information 1111 and displays the help interface 1120 . The help interface 1120 includes prompt information 1121 "Whether the name or password of the working Wi-Fi has been modified, you can try to reset the working Wi-Fi of the device by bringing the mobile phone close to the device."

In some embodiments, the mobile device may not display the first prompt information.

S902, the IoT device periodically broadcasts the first request message by using the second antenna.

The IoT device includes a first antenna and a second antenna. Exemplarily, the first antenna is the aforementioned strong antenna, and the second antenna is the aforementioned weak antenna. In one implementation, the strong antenna and the weak antenna can work at the same time, and the IoT device turns on the weak antenna. In another implementation, the strong antenna and the weak antenna can be switched to each other, and the IoT device switches to use the weak antenna to communicate.

The IoT device uses a weak antenna to periodically broadcast the first request message at a set period (such as 1s, 500ms, etc., which can be specifically set by the user). The transmission distance of the weak antenna is the second distance (for example, 0.3 meters, 0.2 meters, etc., which can be specifically set by the user). The first request message may be received if the mobile device moves within a second distance from the IoT device. Exemplarily, the first request message is a network repair request.

In an implementation manner, after the IoT device periodically broadcasts for a set number of times or for a set duration, the weak antenna is turned off or switched to use the strong antenna for communication (using the first antenna to communicate). In this way, in the subsequent steps, the IoT device can use a strong antenna to exchange information with the mobile device, and the user does not need to carry the mobile device close to the IoT device for a long time. In another implementation manner, the IoT device may also turn off the weak antenna or switch to use the strong antenna for communication (using the first antenna for communication) after the IoT device receives the first response message in S907. This embodiment of the present application does not limit this.

In some embodiments, the first request message includes the device identification and access password of the IoT device, and the session key. The network repair request is used to request the mobile device to send the network configuration parameters; the device ID and access password of the IoT device are used to establish communication between the mobile device and the IoT device; the session key is used for the mobile device to encrypt the network configuration parameters. Exemplarily, the device identifier of the IoT device may include at least one of a MAC address and a Product ID. Product ID can display the specific type of the IoT device (for example, the IoT device is a lamp, air conditioner, refrigerator, etc.), manufacturer, specific model, manufacturer's contact information, customer service number and other information.

In some embodiments, for example, when the IoT device is initially configured to the network, the untrusted IoT server-based solution shown in FIG. 8C is adopted; the first request message further includes a first signature; the first signature is used by the mobile device to verify the identity of the IoT device . Exemplarily, the first signature may be generated using the private key of the IoT device to sign the session key.

S903. The mobile device receives the first request message.

The user brings the mobile device close to the IoT device. If the distance between the mobile device and the IoT device is less than or equal to the second distance of the signal transmitted by the second antenna, the mobile device receives the first request message.

In some embodiments, the first request message includes the first signature. The mobile device receives the first signature, and uses the public key of the IoT device stored in the mobile device to verify the first signature (when the mobile device and the IoT device are initially connected to the network, the other party's public key is obtained). If the mobile device uses the public key of the IoT device to verify that the first signature is signed by the private key of the IoT device, the first request message is verified and passed, and S904 is performed.

S904, the mobile device establishes a communication connection with the IoT device by using the device identification and access password of the IoT device.

Exemplarily, FIG. 12 is a schematic flowchart of establishing a communication connection between a mobile device and an IoT device. The mobile device sends a connection request message to the IoT device (S1201). For example, the connection request message may be an association request message. In an implementation manner, the connection request message includes the identification of the mobile device, the device identification of the IoT device, and the access password. After the IoT device receives the connection request message (S1202), the verification is passed (S1203). If the IoT device is verified through the connection request message (for example, verifying the device identification and access password of the IoT device), a connection response message is sent to the mobile device (S1204). The connection response message is used to confirm that a communication connection is established between the mobile device and the IoT device (for example, establishing a Wi-Fi connection or a Bluetooth connection, etc.). After the mobile device receives the connection response message, a communication connection is established between the mobile device and the IoT device (S1205 and S1206).

S905, the mobile device obtains the device identification and access password of the routing device.

In an implementation manner, the mobile device receives the device identification and access password of the routing device input by the user.

Exemplarily, after a communication connection is established between the mobile device and the IoT device, the mobile device displays a configuration interface for network configuration parameters. The user can select the routing device connected to the IoT device on the configuration interface of the network configuration parameters, and enter the access password of the routing device. Exemplarily, as shown in FIG. 13 , taking a mobile phone as a mobile device as an example, the mobile device 110 displays a network setting interface 1310 , and the network setting interface 1310 includes a “routing device” option 1311 and a “password” input box 1312 . The "Routing Device" option 1311 can display the default routing device SSID (for example, the routing device is the routing device with the strongest signal detected by the mobile phone; for another example, the routing device is the routing device that the IoT device was connected to last time); The “password” input box 1312 inputs the access password corresponding to the routing device displayed in the “routing device” option 1311 . The network setting interface 1310 further includes an "OK" button 1313, and the user can click the "OK" button 1313 to confirm the configuration of the IoT device. The network setting interface 1310 may also include a "Use other Wi-Fi" option 1314, and the user may modify the routing device connected by the IoT device by selecting the "Use other Wi-Fi" option 1314.

In another implementation manner, the mobile device stores the device identification and access password of the routing device. The mobile device obtains the saved device identification and access password of the routing device.

In one example, both the mobile device and the IoT device access one routing device. The user modifies the device ID or access password of the routing device, and the mobile device uses the new device ID and access password of the routing device to access the routing device again, and saves the new device ID and access password. When the IoT device is reconfigured, the mobile device obtains the saved device ID and access password of the routing device. In another example, a mobile device and multiple IoT devices are connected to a routing device. The user has modified the device ID or access password of the routing device. The user uses the mobile device to reconfigure one of the multiple IoT devices. The mobile device receives the device ID and access password entered by the user and saves the device ID and access password. When reconfiguring the remaining IoT devices among multiple IoT devices, the mobile device obtains the device ID and access password of the saved routing device.

S906, the mobile device sends a first response message to the IoT device.

The first response message may include network configuration parameters (including the device identification and access password of the routing device). In one implementation, the network configuration parameter is encrypted using a session key.

In some embodiments, the first response message includes a second signature; the second signature is used by the IoT device to verify the identity of the mobile device. Exemplarily, the second signature is generated using the private key of the user account to sign the session key.

In some embodiments, the first response message includes an authentication credential (when the IoT device is connected to the IoT server for the first time, the IoT server issues an authentication credential for the mobile device and the IoT device respectively). In one implementation, the authentication credential is encrypted with a session key.

S907, the IoT device receives the first response message.

The IoT device receives the first response message, and verifies the identity information (including the second signature or authentication certificate) in the first response message. If the verification is passed, the IoT device obtains the network configuration parameters according to the first response message, and executes S908, IoT The device enters the second working state; if the verification fails, perform S902, and the IoT device periodically broadcasts the first request message by using the second antenna.

In some embodiments, for example, when the IoT device is initially configured to the network, the solution based on the untrusted IoT server shown in FIG. 8C is adopted; the first response message includes the second signature. The IoT device verifies the second signature. In one implementation, the IoT device verifies the second signature using the public key of the user account. If the IoT device uses the public key of the user account to verify that the second signature is signed by the private key of the user account, the verification is passed, and S908 is executed, and the IoT device enters the second working state; if the verification fails, S902 is executed, and the IoT device uses the second working state. The antenna periodically broadcasts the first request message.

In some embodiments, for example, when the IoT device is initially configured to the network, the solution shown in FIG. 8B is adopted; the first response message includes an authentication credential. The IoT device verifies the authentication credential; if the verification passes, execute S908, the IoT device enters the second working state; if the verification fails, execute S902, and the IoT device periodically broadcasts the first request message using the first antenna.

IoT devices verify the identity of mobile devices to ensure security and prevent illegal users from controlling IoT devices.

The IoT device obtains network configuration parameters according to the first response message. For example, the IoT device obtains the encrypted configuration parameters in the first response message, decrypts the encrypted second configuration parameters with the session key, and obtains the configuration parameters.

S908, the IoT device enters the second working state.

In one implementation, IoT devices communicate with mobile devices over Wi-Fi. The IoT device enters the second working state, that is, switches its own Wi-Fi module to the workstation state.

In one implementation, the IoT device communicates with the mobile device via Bluetooth. The IoT device enters the second working state, that is, turning off the Bluetooth. It should be noted that the IoT device can also not turn off the Bluetooth. This embodiment of the present application does not limit this.

S909, the IoT device establishes communication with the routing device according to the distribution network parameters.

In an implementation manner, the connection request message includes the identifier of the IoT device, the device identifier of the routing device, and the access password. After the routing device receives the connection request message (S1402), the verification is passed (S1403). If the routing device verifies that the connection request message is passed (for example, verifying the device identification and access password of the routing device), a connection response message is sent to the IoT device (S1404). The connection response message is used to confirm the establishment of a Wi-Fi connection between the IoT device and the routing device. After the IoT device receives the connection response message, a Wi-Fi connection is established between the IoT device and the routing device (S1405 and S1406).

In the method for repairing a network of an IoT device provided by the embodiment of the present application, the IoT device automatically enters a network repair mode after detecting that it is disconnected from the routing device.

The mobile device obtains the network configuration parameters according to the user input and sends them to the IoT device. The IoT device re-establishes communication with the routing device according to the received distribution network parameters. The network connection can be restored without requiring the user to manually reset the IoT device, which is convenient and quick and avoids data loss. Alternatively, the mobile device sends the saved configuration parameters to the IoT device. The IoT device re-establishes communication with the routing device according to the received distribution network parameters. After the IoT device is disconnected from the routing device, the user can reconfigure the IoT device and restore the network connection by bringing the mobile device close to the IoT device. The network repair process does not require user operations, which is convenient and fast; it also does not require users to manually reset IoT devices, which can avoid data loss.

S1502. The IoT device periodically broadcasts the first request message by using the second transmit power of the antenna.

The transmit power of the antenna of the IoT device can be adjusted. For example, when the transmit power of the antenna is the second transmit power, the distance at which the signal is transmitted is the second distance; when the transmit power of the antenna is the first transmit power, the distance at which the signal is transmitted is the first distance. Wherein, the second transmission power is smaller than the first transmission power, and the second distance is smaller than the first distance. Exemplarily, when the transmit power of the antenna is the second transmit power, the above-mentioned weak antenna function is implemented; when the transmit power of the antenna is the first transmit power, the above-mentioned strong antenna function is implemented.

The IoT device uses the second transmit power of the antenna to periodically broadcast the first request message at a set period (eg, 1s, 500ms, etc., which can be specifically set by the user). When the transmit power of the antenna is the second transmit power, the distance of the transmit signal is the second distance (for example, 0.3 meters, 0.2 meters, etc., which can be set by the user). The first request message may be received if the mobile device moves within a second distance from the IoT device.

In an implementation manner, after the IoT device periodically broadcasts for a set number of times or a set duration, the transmit power of the antenna is adjusted to be the first transmit power, and the first transmit power of the antenna is used for communication. In this way, in the subsequent steps, the IoT device can use a strong antenna to exchange information with the mobile device, and the user does not need to carry the mobile device close to the IoT device for a long time. In another implementation manner, the IoT device may also use the first transmit power of the antenna to communicate in S1507, after the IoT device receives the first response message. This embodiment of the present application does not limit this.

In this method, the network connection can be restored without requiring the user to manually reset the IoT device, which is convenient and quick and can avoid data loss. And the IoT device uses the second transmit power of the antenna (weak antenna) to communicate with the mobile device. Only the mobile device close to the IoT device can obtain the device ID, access password and session key of the IoT device to ensure data security. Please refer to FIG. 16 , which shows a scenario of the IoT device network repair method provided by the embodiment of the present application. In one example, the IoT device 130 includes a strong antenna and a weak antenna, and the transmission distance of the weak antenna is 0.2 meters. The IoT device 130 is connected to the routing device 120 through the distribution network. The user modifies the access password of the routing device 120 , and the IoT device 130 is disconnected from the routing device 120 . IoT device 130 enters network repair mode. The user moves the mobile device 110 to a location less than 0.2 meters from the IoT device 130 . Optionally, the user inputs a new access password of the routing device 120 in the IoT APP of the mobile device 110. IoT device 130 reconnects routing device 120 .

S1701. The IoT device detects that it is disconnected from the routing device.

After the IoT device is connected to the routing device through the distribution network, it may be disconnected from the routing device during the use of the IoT device. For example, if the routing device fails, the device ID of the routing device is modified, or the access password of the routing device is modified, the IoT device will be disconnected from the routing device.

S1702. The IoT device automatically reconnects to the routing device.

In some embodiments, the IoT device detects a disconnection from the routing device and automatically reconnects the routing device. If the routing device roadblock is not recovered, the device ID of the routing device is modified, or the access password of the routing device is modified, the IoT device fails to automatically reconnect to the routing device. In an implementation manner, if the IoT device fails to automatically reconnect to the routing device m times (m>1, the specific value can be set by the user), S1703 is executed, and the IoT device enters the network repair mode. In another implementation manner, the IoT device automatically reconnects to the routing device. If the routing device is not successfully connected after the set duration T1, _S1703 is executed, and the IoT device enters the network repair mode.

The IoT device enters the first working state.

In one implementation, IoT devices communicate with mobile devices over Wi-Fi. The IoT device enters the first working state, that is, switches its Wi-Fi module to the AP state.

Understandably, IoT devices can also communicate with mobile devices through other wireless communication methods. The embodiments of the present application are not listed one by one.

S1704. If the network configuration parameters are not received within the first time period, the IoT device exits the network repair mode.

In an implementation manner, after the IoT device enters the network repair mode, a timer is started, and the duration of the timer is the first duration.

In some embodiments, the IoT device cannot receive the configuration parameters. For example, the IoT device periodically broadcasts the first request message using a weak antenna, and the distance between the mobile device and the IoT device is greater than the second distance of the signal transmitted by the weak antenna, and the mobile device does not receive the first request message, so the network configuration parameters will not be sent. . For another example, the mobile device does not obtain the device identification and access password of the routing device, and thus does not send network configuration parameters.

If the timer expires, the IoT device does not receive the network configuration parameters sent by the mobile device and exits the network repair mode. The IoT device enters the second working state. In one implementation, IoT devices communicate with mobile devices over Wi-Fi. The IoT device enters the second working state, that is, switches its own Wi-Fi module to the workstation state. In another implementation, the IoT device communicates with the mobile device via Bluetooth. The IoT device enters the second working state, that is, turning off the Bluetooth. It should be noted that the IoT device can also not turn off the Bluetooth. This embodiment of the present application does not limit this. Understandably, IoT devices can also communicate with mobile devices through other wireless communication methods. The embodiments of the present application are not listed one by one.

After the IoT device exits the network repair mode, execute S1702, and the IoT device automatically reconnects to the routing device.

In the IoT device network repair method provided by the embodiment of the present application, after the IoT device is disconnected from the routing device, it cyclically enters the automatic reconnection to the routing device and the network repair mode; and so on, until the IoT device automatically connects to the routing device successfully or reconfigures the network successfully. It is convenient and quick to restore the network connection without requiring the user to manually reset the IoT device, and the success rate of network recovery is high. In some embodiments, in the loop process, each time the routing device is automatically reconnected, the number of automatic reconnections m is gradually decreased (or the value _of T1 is gradually decreased); and/or each time the network repair mode is entered When , the value of the first duration increases gradually; so that in the case of being unable to connect to the routing device for a long time, the time in the network repair mode becomes longer and longer, and the probability of successful network repair is improved.
