Description

Network repairing method, electronic equipment and mobile equipment

The present application claims priority from the chinese patent application filed on 29 th 09/2020, filed on the national intellectual property office with application No. 202011052568.X, application name "an IoT device network repair method, ioT device and mobile device", the entire contents of which are incorporated herein by reference.

Technical Field

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

Background

The rapid evolution of the internet of things (internet of things, ioT) has enabled many IoT devices in many areas such as industrial production, smart home, disaster prevention monitoring, logistics tracking, etc. to access the network. The mobile device communicates with other devices in the network through the routing device to which it is connected. However, most IoT devices cannot interact directly with mobile devices held by users, and need to interact with the mobile devices through routing devices. After the IoT device accesses the routing device through the distribution network, the user controls the IoT device through the mobile device.

In some cases, such as routing device identification or access passwords of routing devices are modified, the mobile device cannot control the IoT device. The IoT device needs to enter a distribution network mode, and after the distribution network is again connected to the routing device, the mobile device can control the IoT device again. Thus, the user operation is complicated. In addition, some IoT devices restore factory settings after entering the distribution mode; may result in loss of previously saved data on the IoT device. As such, subsequent mobile device operations on IoT devices are also not facilitated.

Disclosure of Invention

Thus, how IoT devices automatically and quickly access routing devices in situations such as routing device identification or where the access password of the routing device is modified is a problem we need to solve.

In order to solve the technical problems, the application provides a network repair method, electronic equipment and mobile equipment, so that after a routing equipment identifier or an access password of the routing equipment is modified, an IoT device can automatically and quickly access the routing equipment without user operation or loss of data stored before.

In a first aspect, a network repair method is provided, applied to an electronic device, where the electronic device is disconnected from a routing device, and the electronic device includes: a processor; a memory; the first antenna has a transmitting distance of a first distance which is larger than a preset safety distance; the transmitting distance of the second antenna is a second distance, and the second distance is smaller than or equal to a preset safety distance; wherein the first antenna and the second antenna are different antennas; the method comprises the following steps: reconnecting the routing equipment by using a first distribution network parameter of the routing equipment through a first antenna; after the reconnection of the routing equipment fails, periodically sending a first request message through a second antenna; the first request message includes a session key; receiving a first response message of a mobile device connected to the routing device; the first response message includes encrypted second distribution network parameters; responding to the first response message, decrypting the encrypted second distribution network parameters through the session key, and obtaining the second distribution network parameters; the second distribution network parameters are used to connect to the routing device via the first antenna. The first distribution network parameter comprises a first equipment identifier and a first access password of the routing equipment; the second distribution network parameter includes a second device identification of the routing device and a second access password.

In this method, the IoT device disconnects from the routing device due to the device identification or access password modification of the routing device and the automatic reconnection of the routing device fails. IoT devices request mobile devices to send new configuration parameters of routing devices to them via weak antennas (weak and strong antennas are different antennas). The IoT device also sends a session key to the mobile device for the mobile device to encrypt the new configuration network parameters. Because the transmitting distance of the weak antenna is smaller than or equal to the preset safe transmitting distance, only the mobile equipment within the safe distance can receive the session key, and the data safety can be ensured. After the IoT device receives the new distribution network parameters from the mobile device, the IoT device connects to the routing device using the new distribution network parameters. In this way, after the routing device identification or the access password of the routing device is modified, the IoT device automatically and quickly accesses the routing device without user operation and without losing the previously saved data.

In a second aspect, a network repair method is provided, applied to an electronic device, where the electronic device is disconnected from a routing device, and the electronic device includes: a processor; a memory; the antenna, the transmitting distance of the antenna under the first transmitting power is the first distance, the first distance is greater than the preset safe distance; the transmitting distance of the antenna under the second transmitting power is a second distance, and the second distance is smaller than or equal to a preset safety distance; the first transmit power is greater than the second transmit power; the method comprises the following steps: reconnecting the routing equipment by using a first distribution network parameter of the routing equipment through an antenna under the first transmitting power; after the reconnection of the routing equipment fails, periodically sending a first request message through an antenna under the second transmitting power; the first request message includes a session key; receiving a first response message of a mobile device connected to the routing device; the first response message includes encrypted second distribution network parameters; responding to the first response message, decrypting the encrypted second distribution network parameters through the session key, and obtaining the second distribution network parameters; and connecting to the routing equipment by using the second distribution network parameter through the antenna under the first transmission power. The first distribution network parameter comprises a first equipment identifier and a first access password of the routing equipment; the second distribution network parameter includes a second device identification of the routing device and a second access password.

In this method, the IoT device disconnects from the routing device due to the device identification or access password modification of the routing device and the automatic reconnection of the routing device fails. IoT devices request mobile devices to send new configuration parameters of routing devices to them through weak antennas (weak and strong antennas are implemented by different transmit powers of the same antenna). The IoT device also sends a session key to the mobile device for the mobile device to encrypt the new configuration network parameters. Because the transmitting distance of the weak antenna is smaller than or equal to the preset safe transmitting distance, only the mobile equipment within the safe distance can receive the session key, and the data safety can be ensured. After the IoT device receives the new distribution network parameters from the mobile device, the IoT device connects to the routing device using the new distribution network parameters. In this way, after the routing device identification or the access password of the routing device is modified, the IoT device automatically and quickly accesses the routing device without user operation and without losing the previously saved data.

In accordance with the first aspect or the second aspect, or any implementation manner of the first aspect or the second aspect, if the second distribution network parameter is not acquired, the routing device is reconnected using the first distribution network parameter of the routing device.

In the method, after an IoT device is disconnected from a routing device, the IoT device is cycled into an automatic reconnection routing device and a network repair mode; this is done until the IoT device automatically connects to the routing device or the reconfiguration network is successful. The network connection is restored without manually resetting the IoT device by a user, which is convenient and quick and has high success rate of network restoration.

According to the first or second aspect, or any implementation of the first or second aspect, the IoT device receives the second configuration parameters of the routing device; then a switch is made to use the strong antenna to communicate with other devices.

Fig. 1 is a schematic view of a scenario of an IoT device network repair method provided in an embodiment of the present application. As shown in fig. 1, the network system 100 may include a mobile device 110, a routing device 120, and an IoT device 130. In some cases, the network system 100 also includes an IoT server 140.IoT server 140 may be a local server or a cloud server.

Wherein the mobile device 110 is used to configure and control the IoT device 130. The mobile device 110 may share the control of the IoT device 130 to other device controls. The mobile device 110 may be an IoT Application (APP) installed mobile device. Illustratively, mobile device 110 includes, but is not limited to, an on-boardWindows, linux or other operating system. It should also be appreciated that in other embodiments, mobile device 110 may not be a portable device, but rather a desktop computer.

The routing device 120 is to provide network access services for the IoT device 130. For example, ioT device 130 may access a wireless local area network provided by routing device 120. The routing device 120 corresponds to a routing device identification by which the IoT device 130 may access the routing device 120. Illustratively, the routing device identity is a service set identity (service set identifier, SSID). The mobile device 110 may control the IoT device 130 through the routing device 120.

The initial network provisioning process of IoT device 130 and routing device 120 is described below in connection with fig. 2A-2C. The mobile device 110 has previously accessed the routing device 120 and saved the SSID and access password of the routing device 120. As shown in fig. 2A, when IoT device 130 initiates a distribution with routing device 120, ioT device 130 enters a distribution mode. IoT device 130 switches its Wi-Fi module to an Access Point (AP) state. Mobile device 110 may search for the SSID of IoT device 130 through IoT APP, and mobile device 110 accesses the SSID of IoT device 130 to establish communications with IoT device 130.

The mobile device 110 sends the SSID and access password of the routing device 120 to the IoT device 130. The above-described transmissions of the SSID and access password with respect to the routing device 120 may be transmitted after encryption. In some embodiments, mobile device 110 (IoT APP on mobile device 110) and IoT device 130 exchange respective identity credentials to each other. Illustratively, mobile device 110 and IoT device 130 generate their public-private key pairs, respectively, and mobile device 110 (IoT APP on mobile device 110) and IoT device 130 send their public keys to each other and store the public keys of each other. After receiving the SSID and the access password of the routing device 120 sent by the mobile device 110, the IoT device 130 switches its Wi-Fi module to a station state and accesses the routing device 120 using the SSID and the access password of the routing device 120. At this point, as shown in fig. 2B, ioT device 130 accesses routing device 120 and mobile device 110 disconnects the Wi-Fi connection with IoT device 130. Next, the mobile device 110 automatically searches for the SSID of Wi-Fi of the routing device 120 and accesses the routing device 120 using the previously saved access password, as shown in fig. 2C.

The IoT device 130 may be newly purchased by a user or may be moved from another location for the user to connect to the routing device 120. For example, the user is at a cottage with a two-storey building. Upstairs and downstairs each have a routing facility. The user moves the upstairs IoT device 130 down to the downstairs for connecting to the downstairs routing device 120.

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

Alternatively, the bluetooth communication can be replaced by other short-range communication modes. And are not deployed one by one here.

Alternatively, the SSID described above may be replaced with other identifications. So long as each device is able to locate the corresponding device by the identification.

As shown in fig. 3A, after IoT device 130 accesses routing device 120, ioT device 130 communicates with routing device 120 normally. For example, ioT device 130 receives control messages sent by mobile device 110 via routing device 120 and performs corresponding functions. Thereafter, if at least one of the device identification (e.g., SSID) and the access password of the routing device 120 is modified, the IoT device 130 is disconnected from the routing device 120, as shown in fig. 3B. The IoT device 130 may not be able to re-access the routing device 120 after multiple attempts. At this point, the IoT device 130 typically needs to be manually reset to re-enter the distribution mode, again performing the distribution process of fig. 2A-2B described above. For example, ioT device 130 may have a physical key thereon that may be pressed to cause IoT device 130 to enter a distribution network mode. In this way, the user also needs to input relevant information (such as SSID and access password of the routing device 120) again on the IoT APP, click the relevant button again, which is cumbersome to operate and has poor user experience. In addition, ioT devices of some manufacturers automatically restore factory settings after pressing the physical keys and before entering the distribution mode. Namely, for IoT devices of some manufacturers, after the physical key is pressed, factory setting is automatically restored, and then a distribution network mode is entered. In this way, the data (such as some memory data closely related to the user) previously stored by the IoT device is lost, which is inconvenient for the user. For example, ioT locks were previously provided with automatic unlocking when the owner's mobile device was approaching from outside to inside, and the sound "dad was coming back"; the IoT lock was also preceded by an automatic unlock when the mobile device of the female owner was approaching from outside to inside, and a sound "mom was coming back". In the above case, since the IoT lock is restored to the factory setting, the user is required to set the relevant parameters again, which is inconvenient for the user.

The embodiment of the application provides an IoT device network repairing method, which automatically accesses an IoT device to a routing device after at least one of an identification and an access password of the routing device is modified, so that the IoT device is disconnected from the routing device. According to the method, the automatic and rapid access of the IoT device to the routing device can be realized without user operation or restoration of the IoT device to factory settings.

The power management module 137 may also be configured to monitor battery capacity, battery cycle times, battery health (leakage, impedance), and other parameters. In other embodiments, the power management module 137 may also be disposed in the processor 131. In other embodiments, the power management module 137 and the charge management module 136 may be disposed in the same device.

The wireless communication functions of IoT device 130 may be implemented through antenna 1, antenna 2, and wireless communication module 135, among others.

The wireless communication module 135 may provide solutions for wireless communication including Wi-Fi, bluetooth (BT), wireless data transmission modules (e.g., 433mhz,868mhz,915 mhz), etc. applied on the IoT device 130. The wireless communication module 135 may be one or more devices that integrate at least one communication processing module. The wireless communication module 135 receives electromagnetic waves via the antenna 1 or the antenna 2, filters and frequency-modulates the electromagnetic wave signals, and transmits the processed signals to the processor 131.

In this embodiment of the present application, the IoT device 130 may send a broadcast message through the wireless communication module, where the broadcast message may carry a device identifier or a product identifier of the IoT device 130, so that the surrounding second device discovers the IoT device. IoT device 130 may also receive messages sent by the second device through the wireless communication module.

The external memory interface 133 may be used to connect external memory cards, such as Micro SD cards, to enable expanding the storage capabilities of the IoT device 130. The external memory card communicates with the processor 131 through an external memory interface 133 to implement a data storage function. For example, files such as music, video, etc. are stored in an external memory card.

The internal memory 132 may be used to store one or more computer programs, including instructions. The processor 131 may cause the IoT device 130 to perform IoT device network repair methods, as well as various applications, data processing, and the like, provided in some embodiments of the present application by executing the above-described instructions stored in the internal memory 132. The internal memory 132 may include a code storage area and a data storage area. Wherein the code storage area may store an operating system. The data store may store data created during use of the IoT device 130, and the like. In addition, the internal memory 132 may include high-speed random access memory, and may also include non-volatile memory, such as one or more disk storage units, flash memory units, universal flash memory (universal flash storage, UFS), and the like. In some embodiments, the processor 131 may cause the IoT device 130 to perform the IoT device network repair methods provided in embodiments of the present application, as well as other applications and data processing, by executing instructions stored in the internal memory 132, and/or instructions stored in a memory provided in the processor 131.

In one example, fig. 5A illustrates one structure of the IoT devices described above. As shown in fig. 5A, ioT device 130 may include a processor 131, a wireless communication module 135, antenna 1, and antenna 2.

Wherein an antenna 1, such as a strong antenna, and an 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 a signal to be transmitted from the processor 131, and converts the signal into electromagnetic waves to radiate the electromagnetic waves through a strong antenna or a weak antenna. In this embodiment of the present application, a first transmission distance (such as 10 meters, 50 meters, and so on, which may be specifically set by a user) of a strong antenna transmission signal is greater than a second transmission distance (such as 0.2 meters, 0.3 meters, and so on, which may be specifically set by a user) of a weak antenna transmission signal. The second transmitting distance of the weak antenna transmitting signals is smaller than or equal to the preset safe transmitting distance; the secure transmission distance is a secure distance of the secret information that the owner of the IoT device 130 interacts with the IoT device 130 through the mobile device, for example, the secure transmission distance may be preset to be 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, avoid unsafe actions (such as stealing the access password of the routing device), and ensure network security and other security. In some embodiments, the processor 131 may control the switching of strong and weak antennas. When IoT device 130 employs a strong antenna, the mobile device receives the signal sent by IoT device 130 only if the distance between the mobile device and IoT device 130 is less than the first transmit distance; when IoT device 130 employs a weak antenna, the mobile device receives the signal sent by IoT device 130 only if the distance between the mobile device and IoT device 130 is less than the second transmit distance. The first and second emission distances may be referred to as first and second distances, respectively.

In another example, fig. 5B illustrates another structure of the IoT device described above. As shown in fig. 5B, ioT device 130 may include a processor 131, a wireless communication module 135, and an antenna 1. The wireless communication module 135 includes a wireless module 1351 and a variable impedance circuit module 1352. The antenna 1 is used for transmitting and receiving wireless signals. The variable impedance circuit module 1352 may be a circuit composed of variable impedance, an integrated circuit, or the like. The processor 131 adjusts the power applied to the antenna 1 by controlling and adjusting the resistance value of the variable impedance circuit module 1352, thereby controlling the transmission distance when the antenna 1 transmits a wireless signal. For example, when the resistance of the variable impedance circuit module 1352 is the first resistance, the transmission power of the antenna 1 is the second transmission power, and the distance of the transmitted wireless signal is the first transmission distance (implementing the function of a strong antenna); when the resistance of the variable impedance circuit module 1352 is the second resistance, the transmission power of the antenna 1 is the first transmission power, and the distance for transmitting the wireless signal is the second transmission distance (realizing the function of a weak antenna). Wherein the first transmit power is less than the second transmit power; the first emission distance is greater than the second emission distance, which is less than or equal to the preset safe emission distance. The first and second emission distances may be referred to as first and second distances, respectively.

It is to be understood that the architecture illustrated by embodiments of the present application does not constitute a specific limitation on IoT devices. In other embodiments of the present application, ioT devices may include more or fewer components than illustrated, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

In some embodiments, the strong and weak antennas may share a portion of the trace, such as described in the embodiments shown in fig. 6A-6C.

Fig. 6A-6C illustrate, by way of example, three implementations of the weak antenna of fig. 5A. As shown in fig. 6A-6C, the strong and weak antennas may share a portion of the trace.

In the embodiment of the application, the strong antenna and the weak antenna in the IoT device can be switched through the radio frequency switch. Both the weak antenna and the radio frequency switch (shown as a weak antenna in the dashed box in fig. 6A-6C) may be physically located within the shield or the weak antenna may be located within the chip.

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

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

(2) Reducing radiation efficiency, converting a part of electromagnetic wave radiation into heat energy through a resistor to consume;

(3) The return loss is reduced, and part of radio frequency energy is reflected back to the inside of the chip, etc.

The specific implementation of the weak antenna can be as follows:

(i) Shortening the antenna;

(ii) Disconnecting a point in the true antenna path or grounding the point through a resistor, an inductor or a capacitor;

(iii) A shield or the like is used.

It should be appreciated that the particular implementations (i) and (ii) of the weak antennas described above may be implemented on a PCB board or within a chip.

It should also be appreciated that the above-described shield serves to block the path of the electromagnetic wave radiated by the antenna to the receiver for purposes of attenuating the radiation.

It should also be understood that the above-described shortening of the antenna means that the weak antenna is shorter than the strong antenna. The structures of the three weak antennas shown in fig. 6A to 6C are shown as structures in the dashed boxes of fig. 6A to 6C. The strong antenna structures in fig. 6A-6C are all connected to a filter circuit (e.g., pi-type circuit), a matching circuit (e.g., pi-type circuit), and an antenna body (e.g., the antenna body may be a section of metal trace) outside the matching circuit through a Radio Frequency Input Output (RFIO) pin. The weak antenna a shown by the dashed box in fig. 6A, the weak antenna B shown by the dashed box in fig. 6B, and the weak antenna C shown by the dashed box in fig. 6C are different in length but shorter than the strong antennas. The filter circuit is used for preventing interference, and the matching circuit is used for matching with the strong antenna.

Illustratively, as shown in fig. 6A, the weak antenna a may be located within a shield. The weak antenna a may include an RFIO pin of a Wi-Fi chip in a shielding case and a 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 way switch. Wherein, the 2-way switch refers to a switch between a wiring or an RFIO pin and a filter circuit. The wiring or the RFIO pin can be connected with or disconnected from the filter circuit through the 2-way switch. The first switch is a switch which is connected with the RFIO pin or the trace and disconnected with the filter circuit as shown in fig. 6A. It should be appreciated that the 2-way switch in embodiments of the present application may be a single pole double throw switch.

Illustratively, as shown in fig. 6B, the weak antenna B may be located within the shield. The weak antenna b may include an RFIO pin of a Wi-Fi chip in a shielding case, a first switch (a first switch connection resistor) of a 2-way switch, and a matching device. Sometimes, the weak antenna b may also include a first trace between the RFIO pin and the first way switch. Sometimes, the weak antenna b may also include a second trace between the matching device and ground. The matching means may be a resistor. A part of electromagnetic wave radiation can be converted into heat energy to be consumed by the resistor grounding, thereby reducing the radiation efficiency of the weak antenna b. The 2-way switch refers to a switch between the RFIO pin or the first wiring and the resistor as well as the filter circuit, and through the switch, the RFIO pin or the first wiring can be connected with the resistor and disconnected with the filter circuit, or the RFIO pin or the first wiring can be disconnected with the resistor and connected with the filter circuit. The first switch is a switch which is connected with the matching device and disconnected with the filter circuit in the 2 switches.

Illustratively, as shown in fig. 6C, the weak antenna C may be located within the shield. Wherein a matching device (e.g., a resistor) is connected to ground via a chip-matched filter circuit. The weak antenna c may include an RFIO pin of a Wi-Fi chip in a shield, a filter circuit, a first switch of a 2-way switch (a first switch connection resistor), and a matching device (e.g., 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 also include a second trace between the filter circuit and the matching device. Grounding through a matching device (e.g., a resistor) may convert a portion of the electromagnetic wave radiation into heat energy for consumption, thereby reducing the radiation efficiency of the weak antenna c. The 2-way switch refers to a switch between a filter circuit in the shielding case and a matching device and a matching circuit outside the shielding case. The 2-way switch can connect the filter circuit in the shielding case with the matching device and disconnect the filter circuit from the matching circuit outside the shielding case; alternatively, the filter circuit within the shield may be disconnected from the matching device and in communication with the matching circuit outside the shield. The first path of switch is a switch for connecting a filter circuit in the shielding case with a matching device.

It should be understood that the strong antenna in fig. 6A-6B described above may include an RFIO pin, a second switch of 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 fig. 6A-6B may also include a trace between the RFIO pin and a second of the 2-way switches. The second switch is a switch for connecting the RFIO pin and the filter circuit.

The strong antenna in fig. 6C may include an RFIO pin, a filter circuit, a second switch of the 2-way switches, a matching circuit, and an antenna body connected outside the matching circuit. Sometimes, the strong antenna in fig. 6C may also include traces between the RFIO pin and the filter circuit. The second switch is a switch for connecting the filter circuit in the shielding case and the matching circuit outside the shielding case.

It should be appreciated that the wireless communication module 135 shown in fig. 5A may be a Wi-Fi chip or a Wi-Fi chip and a circuit matching the Wi-Fi chip. 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 a circuit matched thereto.

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

By way of example, table 1 shows the communication distances of several different weak antenna structures in combination with different transmit powers.

TABLE 1

The difference between the maximum transmit power and the minimum transmit power of the antenna is correlated due to the characteristics of the physical device within the chip. If the minimum transmission power of the electronic device is reduced to be very low, the maximum transmission power is also reduced, so that the distance requirement in normal operation is not met. Because the structures of different electronic devices are different and the requirements on the safety performance of the electronic devices are different, manufacturers of the electronic devices can adopt different weak antenna structures and transmitting power to ensure the communication distance of the electronic devices. For example, the thickness of the intelligent air conditioner housing may be different for different manufacturers of intelligent air conditioners, and thus the communication distance that the intelligent air conditioner can be found may be different in the case that the weak antenna structure is the same and the transmission power is the same. Different electronic equipment manufacturers can cooperate with the structure of the weak antenna and a certain transmitting power according to the structure of the electronic equipment, so that the safe distance of the electronic equipment to be found can be obtained by combining the test. The user may set the transmission power for three weak antennas (weak antenna a, weak antenna b, and weak antenna c) according to table 1, and adjust the transmission power in combination with the test result, so that the weak antennas reach the corresponding distances when transmitting.

In connection with the above example, the first distance is 5 meters and the second distance is 0.3 meters. When the IoT device employs a strong antenna, the IoT device may communicate with other devices (e.g., mobile devices) if the distance between the IoT device and the other devices (e.g., mobile devices) is less than the first distance (e.g., mobile devices are located at position 1 shown in fig. 7); when the IoT device employs a weak antenna, the IoT device may communicate with other devices (e.g., mobile devices) if the distance between the IoT device and the other devices (e.g., mobile devices) is less than the second distance (e.g., the other devices are located at location 2 shown in fig. 7).

The IoT device network repair method provided by the embodiment of the present application can be applied to the system shown in any one of fig. 1-2C. As shown in fig. 8A, the method may include:

s801, ioT device connects to a routing device.

In one example, referring to fig. 8b, a method of an iot device connecting to a routing device may include:

s8011, the mobile device performs network allocation on the IoT device.

In one implementation, ioT devices and mobile devices discover each other over bluetooth and establish a bluetooth connection. The user may enter a first network distribution parameter on the mobile device (e.g., the first network distribution parameter includes a first device identification of the routing device and a first access password). The mobile device sends the first distribution network parameters to the IoT device via bluetooth.

In another implementation, after the IoT device is started, switching its Wi-Fi module to the AP state; the user enters a device identification and an AP password of the IoT device on the mobile device, and the mobile device establishes communication with the IoT device. The user enters a first distribution network parameter on the mobile device (e.g., the first distribution network parameter includes a first device identification of the routing device and a first access password). The mobile device sends the first distribution network parameter to the IoT device.

And S8012, the IoT device connects the routing device according to the received first distribution network parameter.

In some embodiments, the IoT device registers with the IoT server after being networked, so that the IoT server's services may be received. The method may further comprise:

s8013, the IoT device registers with the IoT server.

S8014, the IoT server sends a local authentication control code to the IoT device.

S8015, the IoT server sends a local authentication control code to the mobile device.

In one example, referring to fig. 8c, a method of an iot device connecting to a routing device may include:

s801a, mobile equipment performs network allocation on an IoT device; and the mobile device and IoT device exchange identity credentials.

The mobile device and IoT device send their own identity credentials to each other. Illustratively, a mobile device (IoT APP on the mobile device) and an IoT device each generate their own public-private key pair, and the mobile device and IoT device each send their own public key to each other and store the public key of each other. The identity credential of the mobile device is the public key of the mobile device; the identity credential of the IoT device is the public key of the IoT device.

S801b, the IoT device connects the routing device according to the received first distribution network parameter.

S801c, the IoT device registers with the IoT server.

In this example, the IoT server scheme is not trusted. Upon initial provisioning, the mobile device and the IoT device exchange identity credentials; in the subsequent flow, the mobile device and IoT device perform authentication of the identity credential even though the IoT server relays the message.

S802, the IoT device disconnects from the routing device.

During IoT device use, the connection may be disconnected from the routing device. For example, failure of the routing device, modification of the device identification of the routing device, modification of the access password of the routing device, etc., may result in disconnection of the IoT device from the routing device.

S803, ioT device auto-reconnect routing device fails.

The IoT device detects a disconnection from the routing device and initiates an automatic reconnection routing device procedure using the saved device identification and access password of the routing device. If the IoT device is disconnected from the routing device due to a transient failure of the routing device, the IoT device may repair the network connection by automatically reconnecting the routing device. If the device identifier of the routing device is modified, the access password of the routing device is modified, and the like, because the network allocation parameters used by the IoT device are unchanged when the routing device is automatically reconnected, the network connection cannot be repaired through the automatic reconnection routing device. The IoT device fails to automatically reconnect the routing device m times.

S804, the IoT device obtains a device identification and an access password of the routing device from the mobile device.

The IoT device triggers a reconfiguration of the network, sends a network repair request to the mobile device requesting the mobile device to send the network parameters. The mobile device receives the device identification and the access password of the routing device input by the user, or obtains the device identification and the access password of the local routing device, and sends the IoT device network allocation parameters to the IoT device.

S805, the IoT device reconnects the routing device according to the acquired device identifier and access password of the routing device.

The IoT device receives the distribution network parameters and reconnects the routing device according to the distribution network parameters.

According to the method for repairing the network of the IoT device, after the IoT device detects that the device is disconnected from the routing device, new network allocation parameters are acquired from the mobile device, and the device is re-accessed; there is no need to reboot the IoT device. The method can realize the network repair of the IoT device more quickly and conveniently, and avoid the data loss caused by restarting the IoT device.

A method for automatically repairing a network after an IoT device disconnects from a routing device will be described in detail below with reference to the accompanying drawings.

An embodiment of the present application provides an IoT device network repair method, as shown in fig. 9, which may include:

s901, the IoT device detects that the connection from the routing device is disconnected, and the automatic reconnection of the routing device fails m times, and enters a network repair mode. The IoT device enters a first operational state.

For example, the user modifies the access password of the routing device. When the IoT device reconnects to the routing device, the device identification of the routing device exists, but the access password is incorrect and the automatic reconnection to the routing device fails m times. As another example, the user modifies the device identification of the routing device. When the IoT device reconnects to the routing device, the device identity before modification is not found, and the automatic reconnection to the routing device fails m times. IoT devices enter network repair mode. Wherein m >1, the specific value may be set by the user.

The IoT device enters a first operational state.

In one implementation, the IoT device communicates with the mobile device over Wi-Fi. The IoT device enters a first operational state, i.e., switches its Wi-Fi module to an AP state.

In one implementation, ioT devices communicate with mobile devices over bluetooth. The IoT device enters a first operational state, bluetooth is turned on.

It is to be appreciated that IoT devices may also communicate with mobile devices via other wireless communication means. The embodiments of the present application are not listed one by one.

In one example, the IoT device includes an indicator light that may flash by the IoT device to prompt the IoT device to enter a network remediation mode. In another example, the IoT device may voice play a hint message prompting the IoT device to enter a network repair mode.

S901', the mobile device displays the first prompt.

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 one example, as shown in fig. 10, a mobile device sends a first keep-alive request to IoT devices in a first period (e.g., 1 s). After receiving the first keep-alive request, the IoT device sends a first keep-alive response to the mobile device. The mobile device receives the first keep-alive response within a preset duration (e.g., 10 ms), then determines that the IoT device is normally connected to the routing device (not offline). It can be appreciated that the mobile device sends a first keep-alive request to the IoT device via the routing device and receives a first keep-alive response via the routing device. If the mobile device does not receive the first keep-alive response within a preset duration (e.g., 10 ms), 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 duration (e.g., 10 ms), the first keep-alive request may be sent to the IoT device again. If the number of times the mobile device sends the first keep-alive request to the IoT device exceeds a preset number of times and the first keep-alive response is not received, determining that the IoT device is offline.

In one implementation, the mobile device displays a first hint information. The first hint information is used to hint the user to bring the mobile device close to the IoT device. For example, using a mobile phone as the mobile device, as shown in fig. 11, the mobile device 110 displays a device management interface 1110, where the device management interface 1110 includes the running information of the IoT device "smart desk lamp". The mobile device detects that the intelligent desk lamp is not connected with the routing device, and displays prompt information 1111 that the device is offline. In one example, the mobile device receives a user click on the prompt 1111, displaying a help interface 1120. Help interface 1120 includes prompt 1121 "if the name or password of work Wi-Fi was modified, you can attempt to bring the handset close to the device to reset the work Wi-Fi of the device. "

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

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

The IoT device includes a first antenna and a second antenna. Illustratively, the first antenna is the strong antenna and the second antenna is the weak antenna. In one implementation, the strong antenna and the weak antenna may operate simultaneously, with the IoT device turning on the weak antenna. In another implementation, the strong and weak antennas may switch to each other, and the IoT device switches to communicate using the weak antenna.

The IoT device periodically broadcasts the first request message at a set period (e.g., 1s, 500ms, etc., which may be specifically set by the user) using the weak antenna. The weak antenna has a transmission distance of a second distance (e.g., 0.3 meters, 0.2 meters, etc., which may 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. Illustratively, the first request message is a network repair request.

In one implementation, after the IoT device periodically broadcasts for a set number of times or a set duration, the weak antenna is turned off or switched to use strong antenna communication (using the first antenna communication). In this way, in subsequent steps, the IoT device may interact information with the mobile device using a strong antenna, without requiring the user to carry the mobile device in close proximity to the IoT device for long periods of time. In another implementation, the IoT device may also turn off the weak antenna or switch to communicating using the strong antenna (communicating using the first antenna) after the IoT device receives the first response message at S907. The embodiments of the present application are not limited in this regard.

In some embodiments, the first request message includes a device identification and access password of the IoT device, and a session key. The network repair request is used for requesting the mobile equipment to send the network distribution parameters; an IoT device identification and access password for establishing communication with the IoT device by the mobile device; the session key is used for encrypting the distribution network parameters by the mobile device. For example, the device identification of the IoT device may include at least one of a MAC address and a Product ID. The Product ID may show various information of a specific type of the IoT device (e.g., the IoT device is a lamp, an air conditioner, a refrigerator, etc.), a manufacturer, a specific model number, a manufacturer contact, a customer service phone, etc.

In some embodiments, for example, upon initial provisioning of the IoT device, an untrusted IoT server-based scheme shown in fig. 8C is employed; the first request message further includes a first signature; the first signature is used by the mobile device to verify an identity of the IoT device. For example, the first signature may be generated using a private key signature session key of the IoT device.

S903, the mobile device receives the first request message.

The user carries the mobile device near the IoT device, and if the distance of the mobile device from the IoT device is less than or equal to a second distance at which the second antenna transmits the signal, the mobile device receives the first request message.

In some embodiments, the first request message includes a first signature. The mobile device receives the first signature and verifies the first signature using the public key of the IoT device stored by the mobile device (the public key of the other party is obtained when the mobile device and the IoT device initially join the network). If the mobile device verifies that the first signature is signed by the private key of the IoT device using the public key of the IoT device, the first request message is verified to pass, and S904 is performed.

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

Fig. 12 is a flow chart illustrating a method for a mobile device to establish a communication connection with 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 one implementation, the connection request message includes an identification of the mobile device, a device identification of the IoT device, and an access password. After the IoT device receives the connection request message (S1202), it verifies whether it passes (S1203). If the IoT device verifies the pass of the connection request message (e.g., verifies the device identification and access password of the IoT device), a connection response message is sent to the mobile device (S1204). Wherein the connection response message is used to confirm that a communication connection (e.g., a Wi-Fi connection or a bluetooth connection, etc.) is established between the mobile device and the IoT device. 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 acquires the device identifier and the access password of the routing device.

In one implementation, a mobile device receives a device identification and an access password of a routing device entered by a user.

For example, after establishing a communication connection between the mobile device and the IoT device, the mobile device displays a distribution network parameter configuration interface. The user may select a routing device to which the IoT device is connected at the distribution network parameter configuration interface and enter an access password for the routing device. For example, as shown in fig. 13, using a mobile phone as an example, the mobile device 110 displays a network setup interface 1310, where the network setup interface 1310 includes a "routing device" option 1311 and a "password" input box 1312. The "routing device" option 1311 may display a default routing device SSID (e.g., the routing device detected the strongest signal for the handset; e.g., the routing device was the last connected routing device for the IoT device); the user may enter an access password corresponding to the routing device displayed in the "routing device" option 1311 at the "password" input box 1312. The network settings interface 1310 also includes a "ok" button 1313, which the user may click on to determine to provision the IoT device. The network settings interface 1310 may also include a "use other Wi-Fi" option 1314, which the user may modify the routing device to which the IoT device is connected by selecting the "use other Wi-Fi" option 1314.

In another implementation, the mobile device maintains a device identification and access password for the routing device. The mobile device obtains the stored 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 identification or access password of the routing device, and the mobile device re-accesses the routing device using the new device identification and access password of the routing device and saves the new device identification and access password. When the IoT device re-configures the network, the mobile device obtains the saved device identification and access password of the routing device. In another example, a mobile device and multiple IoT devices access one routing device. The user modifies the device identification or access password of the routing device. The user uses the mobile device to reconfigure the network to one of the plurality of IoT devices, and the mobile device stores the device identification and the access password after receiving the device identification and the access password entered by the user. When the network is reconfigured for the rest of the plurality of IoT devices, the mobile device obtains the saved device identifier and access password of the routing device.

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

The first response message may include the distribution network parameters (including the device identification and access password of the routing device). In one implementation, the distribution network parameters are 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. Illustratively, the second signature is generated using a private key of the user account to sign the session key.

In some embodiments, the first response message includes authentication credentials (when the IoT device first joins the network, the IoT server issues the authentication credentials for the mobile device and the IoT device, respectively). In one implementation, the authentication credentials are encrypted with a session key.

S907, the IoT device receives the first response message.

The IoT device receives the first response message, verifies identity information (including the second signature or authentication credentials) in the first response message, and if the verification is passed, the IoT device obtains the network allocation parameters according to the first response message, performs S908, and enters the second working state; if the authentication is not passed, S902 is performed, the IoT device periodically broadcasts a first request message using a second antenna.

In some embodiments, for example, upon initial provisioning of the IoT device, an untrusted IoT server-based scheme shown in fig. 8C is employed; the first response message includes a second signature. The IoT device verifies the second signature. In one implementation, the IoT device verifies the second signature using a public key of the user account. If the IoT device verifies that the second signature is signed by the private key of the user account using the public key of the user account, the verification passes, S908 is executed, and the IoT device enters a second working state; if the authentication is not passed, S902 is performed, the IoT device periodically broadcasts a first request message using a second antenna.

In some embodiments, for example, when an IoT device initially joins a network, the scheme shown in fig. 8B is employed; the first response message includes authentication credentials. The IoT device verifies the authentication credentials; if the authentication is passed, executing S908, the IoT device entering a second operational state; if the authentication is not passed, S902 is performed, the IoT device periodically broadcasts a first request message using a first antenna.

The IoT device verifies the identity of the mobile device, ensures security, and prevents illegal users from controlling the IoT device.

The IoT device obtains the distribution network parameters according to the first response message. For example, the IoT device obtains the encrypted network allocation parameter in the first response message, decrypts the encrypted second network allocation parameter using the session key, and obtains the network allocation parameter.

S908, the IoT device enters a second operational state.

In one implementation, the IoT device communicates with the mobile device over Wi-Fi. The IoT device enters a second operational state, i.e., switches its Wi-Fi module to a workstation state.

In one implementation, ioT devices communicate with mobile devices over bluetooth. The IoT device enters a second operational state, bluetooth is turned off. Note that the IoT device may not turn off bluetooth. The embodiments of the present application are not limited in this regard.

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

The IoT device reestablishes communication with the routing device according to the received configuration parameters. Fig. 14 is a schematic flow diagram illustrating a process for establishing a communication connection between an IoT device and a routing device. The IoT device sends a connection request message to the routing device (S1401). For example, the connection request message may be an association request message. In one implementation, the connection request message includes an identification of the IoT device, a device identification of the routing device, and an access password. After receiving the connection request message (S1402), the routing device verifies whether it passes (S1403). If the routing device verifies the pass of the connection request message (e.g., verifies the device identification and access password of the routing device), a connection response message is sent to the IoT device (S1404). Wherein the connection response message is to confirm establishment of the 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).

According to the IoT device network repairing method, after the IoT device detects that the IoT device is disconnected from the routing device, the IoT device automatically enters a network repairing mode. The IoT device enters a first operational state such that the mobile device may access the IoT device.

The mobile device obtains the distribution network parameters according to user input and sends the distribution network parameters to the IoT device. The IoT device reestablishes communication with the routing device according to the received configuration parameters. The network connection can be restored without requiring the user to manually reset the IoT device, which is convenient and fast and can avoid data loss. Alternatively, the mobile device sends the saved distribution network parameters to the IoT device. The IoT device reestablishes communication with the routing device according to the received configuration parameters. After the IoT device is disconnected from the routing device, the user brings the mobile device close to the IoT device, and can reconfigure the network to the IoT device to restore the network connection. The network repairing process does not need user operation, and is convenient and quick; nor does the user need to manually reset the IoT device, data loss can be avoided. And the IoT device communicates with the mobile device using a second antenna (weak antenna), only the mobile device near the IoT device can obtain the device identification and access password of the IoT device, and the session key, so as to ensure data security.

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

The transmit power of the antennas of the IoT device may be adjusted. For example, when the transmission power of the antenna is the second transmission power, the distance of the transmission signal is the second distance; when the transmitting power of the antenna is the first transmitting power, the distance of the transmitting signal is the first distance. The second transmitting power is smaller than the first transmitting power, and the second distance is smaller than the first distance. The weak antenna function is implemented when the transmission power of the antenna is the second transmission power; when the transmitting power of the antenna is the first transmitting power, the strong antenna function is realized.

The IoT device periodically broadcasts the first request message at a set period (e.g., 1s, 500ms, etc., which may be specifically set by the user) using the second transmit power of the antenna. When the transmission power of the antenna is the second transmission power, the distance of the transmission signal is the second distance (for example, 0.3 meter, 0.2 meter, 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.

In one implementation, 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 a first transmit power, and the first transmit power of the antenna is used for communication. In this way, in subsequent steps, the IoT device may interact information with the mobile device using a strong antenna, without requiring the user to carry the mobile device in close proximity to the IoT device for long periods of time. In another implementation, the IoT device may also communicate using the first transmit power of the antenna after the IoT device receives the first response message at S1507. The embodiments of the present application are not limited in this regard.

In some embodiments, the first request message includes a network repair request, a device identification and access password of the IoT device, and a session key. The network repair request is used for requesting the mobile equipment to send the network distribution parameters; an IoT device identification and access password for establishing communication with the IoT device by the mobile device; the session key is used for encrypting the distribution network parameters by the mobile device. Illustratively, the device identification of the IoT device includes at least one of a MAC address and a Product ID.

Specific steps of S1503 to S1509 may refer to S903 to S909, and will not be described here.

The mobile device sends the distribution network parameters to the IoT device. The IoT device reestablishes communication with the routing device according to the received configuration parameters. According to the method, the network connection can be recovered without manually resetting the IoT device by a user, so that the method is convenient and quick, and data loss can be avoided. And the IoT device communicates with the mobile device using the second transmit power of the antenna (weak antenna), only the mobile device near the IoT device can obtain the device identification and access password of the IoT device and the session key, ensuring data security. Referring to fig. 16, a scenario of an IoT device network repair method provided in an embodiment of the present application is shown. In one example, ioT device 130 includes a strong antenna and a weak antenna, the weak antenna transmitting a distance of 0.2 meters. IoT device 130 connects routing device 120 through the distribution network. The user modifies the access password of the routing device 120 and the IoT device 130 disconnects 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 enters a new access password for the routing device 120 at the IoT APP of the mobile device 110. IoT device 130 reconnects routing device 120.

The embodiment of the application also provides an IoT device network repairing method, as shown in fig. 17, which may include:

s1701, ioT device detects disconnection from the routing device.

After the IoT device accesses the routing device through the distribution network, the IoT device may be disconnected from the routing device during use of the IoT device. For example, failure of the routing device, modification of the device identification of the routing device, modification of the access password of the routing device, etc., may result in disconnection of the IoT device from the routing device.

S1702, ioT device automatically reconnects the routing device.

In some embodiments, ioT devicesThe disconnection from the routing device is detected and the routing device is automatically reconnected. If the route device barrier is not restored, the device identification of the route device is modified, or the access password of the route device is modified, and the IoT device automatically reconnects the route device fails. In one implementation, if the IoT device automatically reconnects the routing device m times (m>1, a specific value may be set by the user) fail, S1703 is performed and the IoT device enters a network repair mode. In another implementation, the IoT device automatically reconnects the routing device if at the set time period T ₁ After that, the routing device is not successfully connected, S1703 is performed, and the IoT device enters a network repair mode.

S1703, the IoT device enters a network repair mode.

The IoT device enters a first operational state.

In one implementation, the IoT device communicates with the mobile device over Wi-Fi. The IoT device enters a first operational state, i.e., switches its Wi-Fi module to an AP state. In another implementation, the IoT device communicates with the mobile device over bluetooth. The IoT device enters a first operational state, bluetooth is turned on. It is to be appreciated that IoT devices may also communicate with mobile devices via other wireless communication means. The embodiments of the present application are not listed one by one.

In one implementation, 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 does not receive the distribution network parameters. For example, the IoT device periodically broadcasts the first request message using the weak antenna, and the mobile device is farther from the IoT device than the second distance the weak antenna transmits the signal, and the mobile device does not receive the first request message, and therefore does not transmit the distribution network parameters. For another example, the mobile device does not obtain the device identification and access password of the routing device, so that the network distribution parameters are not sent.

If the timer times out, the IoT device does not receive the configuration parameters sent by the mobile device and exits the network repair mode. The IoT device enters a second operational state. In one implementation, the IoT device communicates with the mobile device over Wi-Fi. The IoT device enters a second operational state, i.e., switches its Wi-Fi module to a workstation state. In another implementation, the IoT device communicates with the mobile device over bluetooth. The IoT device enters a second operational state, bluetooth is turned off. Note that the IoT device may not turn off bluetooth. The embodiments of the present application are not limited in this regard.

According to the method for repairing the network of the IoT device, the IoT device is circularly connected to the automatic reconnection routing device and the network repairing mode after being disconnected from the routing device; this is done until the IoT device automatically connects to the routing device or the reconfiguration network is successful. The network connection is restored without manually resetting the IoT device by a user, which is convenient and quick and has high success rate of network restoration. In some embodiments, the number of automatic reconnections m is gradually reduced (or T) each time the automatic reconnection of the routing device is performed during a cycle ₁ Gradually decreasing in value); and/or the value of the first time period is gradually increased each time the network repair mode is entered; under the condition that the routing equipment cannot be connected for a long time, the network repair mode is longer and longer, and the success rate of network repair is improved.
