The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. The server 104 may be implemented as a stand-alone server or a server cluster comprised of multiple servers.
In one embodiment, as shown in fig. 2, a flowchart of a method for repairing a network connection is provided, and the method is applied to an intelligent gateway, and includes steps S110 to S130.
And step S110, when the offline device exists, generating a scanning instruction to instruct each online device to scan.
Specifically, in this embodiment, a plurality of devices are connected to an intelligent gateway through a wireless technology, and when the intelligent gateway finds that a device that is disconnected exists among the plurality of devices, a scanning instruction is generated and sent to a device that is still online, so as to instruct all online devices to start a scanning mode and scan the devices around the intelligent gateway. Meanwhile, when the intelligent gateway finds that the off-line equipment exists in the plurality of equipment, the intelligent gateway can start the scanning module to scan the peripheral off-line equipment. When the intelligent gateway scans the offline device, the scanning result of the intelligent gateway can be recorded.
The scanning may be, but is not limited to, WIFI scanning, zigBee scanning, BLE scanning. However, with the rapid development of the semiconductor technology, the WIFI chip scheme or the ZigBee chip scheme is basically provided with BLE modules without increasing the cost, and therefore, in this embodiment, specifically, all the devices that have BLE modules around and are off-line for broadcasting can be scanned through the BLE scanning technology, that is, the off-line devices are not limited to being WIFI devices, zigBee devices, or BLE devices.
Step S120, receiving the scanning result generated by each online device, respectively, where the scanning result includes the address of each offline device within the signal range of the online device.
Specifically, the intelligent gateway in this embodiment is further configured to receive a scanning result generated by all online devices after instructing all online devices to scan their respective peripheral devices, where the scanning result includes addresses of all offline devices scanned by all online devices within a scanning signal range. It can be understood that, when the online device does not scan the peripheral dropped devices, the scanning result of the address of the dropped device may or may not be fed back to the intelligent gateway. Meanwhile, it is easy to understand that the scanning result also includes the address of the online device used for scanning, and the intelligent gateway can know the mapping relationship between the online device and the offline device scanned in the scanning result according to the scanning result. In addition, when the online device and the intelligent gateway scan the surrounding devices, not only the address of the offline device but also the addresses of the online devices and/or the intelligent gateway may be scanned, and at this time, the scanning result includes not only the mapping relationship between the online device and the offline device, but also the mapping relationship between the online device and the online device, or the mapping relationship between the online device and the intelligent gateway. When the intelligent gateway receives the scanning result, the scanning result can be screened to obtain the mapping relation between the scanned online equipment and the scanned offline equipment.
Step S130, generating a support instruction carrying support information according to the scanning result to instruct the target online device to establish connection with each corresponding offline device, where the support information includes a corresponding relationship between the target online device and at least one offline device.
Specifically, in this embodiment, the intelligent gateway determines, according to the scanning result, an online device that can be used to initiate a network connection request to the offline device, marks the online device as a target online device, and generates a support instruction carrying support information to indicate the target online device to connect with the corresponding offline device. When the number of the support instructions is multiple, the intelligent gateway can respectively send the multiple support instructions to the multiple target online devices in a one-to-one correspondence manner.
The network connection between the target online device and the offline device can be WIFI connection, zigBee connection or BLE connection. As described above, the BLE module is set in both the WIFI device and the ZigBee device, so the target online device and the offline device in this embodiment can be connected more widely through the BLE module, that is, the target online device and the offline device can be the WIFI device and the ZigBee device, respectively, and can also be the WIFI device and the WIFI device, and the like.
Specifically, when the device that drops a line in this embodiment sends a broadcast signal, its BLE slave mode is started, so that when the target device is connected to the corresponding device that drops a line, the target device is connected to the corresponding device that drops a line by starting its BLE Master mode.
For the convenience of understanding the relationship between the online device, the target online device and the dropped device, the following examples are only used for illustration, but not for limiting the scope of the present application. For example, among the plurality of online devices are: online device 1, online device 2, and online device 3; the plurality of drop devices include: a line drop device 1 and a line drop device 2. If the online device 2 can scan the dropped device 1 and the dropped device 2, and the online device 1 and the online device 3 cannot scan the dropped device 1 and the dropped device 2, it is determined that the online device 2 is a target online device, and support information generated by the intelligent gateway is used for indicating that the online device 2 is connected with the dropped device 1 and/or the dropped device 2, and the dropped device 1 and/or the dropped device 2 can implement communication through a relay of the online device 2.
In this embodiment, when finding the offline device, the intelligent gateway scans the offline device by indicating all online devices, and specifies a target offline device to be connected with each offline device, thereby solving the problem of connection stability in internet of things network connection.
In one embodiment, as shown in fig. 3, a flow chart of a method for repairing a network connection is provided, and the step S110 further includes steps S140 to S150.
Step S140, receiving heartbeat packets sent by each online device.
Specifically, the intelligent gateway in this embodiment receives a heartbeat packet that is reported by the online device at a certain period, for example, a heartbeat packet that is reported once in one minute. It can be understood that the heartbeat packet reporting period in this embodiment is only used for example, and is not used to limit the protection scope of this application, and those skilled in the art can reasonably set the heartbeat packet reporting period according to the actual application situation.
And step S150, judging that the offline device exists when not receiving all heartbeat packets of the online device.
Specifically, when the intelligent gateway does not receive heartbeat packets of the same device in at least two continuous periods, it is determined that a dropped device exists in the network. The online device and the intelligent gateway in this embodiment have a heartbeat mechanism, so that the intelligent gateway can know the online states of all connected devices.
In one embodiment, when the intelligent gateway receives a notification signal generated by a target online device, the intelligent gateway sends the notification signal to each online device. The notification signal is a signal generated after the target online equipment and the offline equipment are re-connected to notify each online equipment, the target online equipment performs proxy after the original offline equipment is re-networked, and subsequent information is forwarded to the original offline equipment by the target online equipment so as to finally realize the transmission of network information.
In one embodiment, the scanning result further includes the signal strength of the broadcast signal of each offline device scanned by each online device, as shown in fig. 4, a flowchart of a method for repairing network connection is provided, and the step S130 generates the support instruction carrying the support information according to the scanning result, including steps S131 to S132.
Step S131, obtaining the maximum value of a plurality of signal strengths corresponding to the same offline device, and using the online device corresponding to the maximum value as the target online device corresponding to the current offline device.
Specifically, when the online device in this embodiment scans the peripheral offline device, the signal strength of the broadcast signal scanned to the offline device is also recorded. And the intelligent gateway selects the target online equipment from the online equipment which scans the broadcast signal by taking the maximum value of the intensity of the broadcast signal scanned by each online equipment in the scanning result as a standard. For example, the online device includes: online equipment 1 and online equipment 2, the equipment that falls off the line includes: the apparatus 1 is disconnected. The on-line device 1 scans that the intensity of the broadcast signal of the off-line device 1 is-10 dbm, and the on-line device 2 scans that the intensity of the broadcast signal of the off-line device 1 is-100 dbm. The presence device 1 is taken as the target presence device. It is understood that the signal strength in the present embodiment is only for example and is not used to limit the protection scope of the present application.
Step S132 is to acquire the addresses of the target online apparatuses, and generate support instructions using the addresses of the respective offline apparatuses and the addresses of the target online apparatuses corresponding to the respective offline apparatuses as support information.
Wherein the support information includes a correspondence between the target online device and at least one dropped device. In this embodiment, the intelligent gateway selects the online device with the maximum broadcast signal strength scanned to the offline device from the online devices scanning the broadcast signals of the offline device as the target device by using the maximum broadcast signal strength scanned to the offline device by each online device in the scanning result as a standard, so as to ensure the stability of subsequent network connection.
In one embodiment, the scanning result further includes scanning time of each offline device scanned by each online device, and the step S131 includes:
and acquiring the sequence of a plurality of scanning times corresponding to the same offline device, and taking the online device which is firstly scanned to the current offline device as the target online device corresponding to the current offline device.
Specifically, in this embodiment, after the same offline device is scanned by multiple online devices, the intelligent gateway may select, according to the time sequence of the offline devices scanned by the multiple online devices, the online device that is scanned to the current offline device first, as the target online device. Therefore, the network connection can be quickly repaired, and the risk of delaying the transmission of network information is reduced.
In one embodiment, the scanning result further includes the number of loads of each online device scanned to the offline device, and the step S131 includes:
and acquiring the load quantity of online equipment corresponding to the same offline equipment, and selecting the online equipment with the least load quantity as target online equipment of the current offline equipment.
Specifically, in this embodiment, after the same offline device is scanned by multiple online devices, the intelligent gateway may perform screening according to the load number of each online device scanned to the offline device, where the load number of the online device is the number of other online devices already connected to the current online device, and selects a target online device with the smallest load number in the online devices as the current offline device. Therefore, the robustness of network connection is enhanced, the problems that information transmission is too slow due to too high load quantity of the online equipment is reduced, and the hardware equipment is high in temperature due to too high load quantity of the online equipment are solved.
In one embodiment, the scanning result includes the signal strength of the broadcast from the online device to the offline device, the scanning time, and the load amount of the online device. According to the embodiment, the online equipment which finds the same offline equipment is comprehensively scored according to the signal intensity, the scanning time and the load number of the online equipment, and the optimal online equipment is determined to be the target online equipment. Therefore, the stability of the network connection after repair is enhanced.
In one embodiment, when the offline device exists, a prompt signal is generated and sent to the mobile terminal to prompt the user that the offline device exists in the network.
In this embodiment, a prompt signal is generated through the intelligent gateway to prompt a user that there is a device disconnected in a network. For example, in an intelligent home scene, if a sweeping robot of an original online device is disconnected, a user can know that the sweeping robot is disconnected through a mobile terminal, the user can select human intervention and can wait for restoration of network connection, and after the network connection is restored, the intelligent gateway rejoins the information of the sweeping robot into the network and sends the information to the user so as to facilitate the user to acquire the network state in the intelligent home.
In one embodiment, as shown in fig. 5, a flowchart of a method for repairing a network connection is provided, and the method is applied to an online device, and includes steps S160 to S180.
And step S160, receiving a scanning instruction sent by the intelligent gateway.
And S170, responding to the scanning instruction to scan the offline equipment in the signal range, generating a scanning result and sending the scanning result to the intelligent gateway.
Specifically, as described above, the WIFI scan, the ZigBee scan, and the BLE scan may be performed. The scanning in this embodiment may specifically be that the online devices turn on their BLE modules, scan their surrounding broadcast signals, generate scanning results according to their respective scanning, and send their respective scanning results to the intelligent gateway. In this embodiment, each online device scans by starting the BLE module to find a broadcast signal in a signal range, and each offline device sends the broadcast signal by starting the BLE module. Wherein, in order to reduce the consumption that BLE module starts and brings, each online equipment can send the scanning result to intelligent gateway through the original network of normally connecting before sending the scanning result to intelligent gateway, for example, WIFI equipment sends the scanning result to intelligent gateway through the original WIFI network of normally connecting. Each online device may also turn off its own scanning function when sending the scanning result to the intelligent gateway, or after sending the scanning result to the intelligent gateway, so as to reduce power consumption.
Specifically, when the BLE module of the online device in this embodiment is turned off, and the online device receives a new scanning instruction, the online device may further start the BLE module in response to the new scanning instruction and perform scanning. And when the BLE module of the online device is not turned off, the online device responds to a new scanning instruction to directly scan after receiving the new scanning instruction.
Specifically, after the online devices send respective scanning results to the intelligent gateway, the intelligent gateway generates a support signal carrying support information according to the scanning results, where the support information includes a correspondence between the target online device and the offline device, and therefore, the target online device initiates a connection request to the specified offline device according to the support information when receiving the support instruction, where the target online device is designated as an online device of the target online device. The connection request may be a WIFI connection request, may be a ZigBee connection request, and may also be a BLE connection request, which is not limited herein. Since the existing WIFI device and the ZigBee device both include a BLE module, in this embodiment, specifically, the target online device sends a connection request to the drop device in a BLE connection request manner, so as to implement the requirement that the target online device and the drop device must be the same network device without limitation, and implement wider device network connection.
In one embodiment, each online device is configured with a device validity token corresponding to each online device, before a target device initiates a network connection request to each offline device, the device validity token of each offline device is verified, whether each offline device corresponding to the network connection request to be initiated is a legal device is judged, and only a network connection request is initiated to the legal device, so as to ensure network security and prevent an illegal device from joining a network.
In one embodiment, the online device includes a parent node device and a child node device, the child node device is directly connected with the parent node device and is connected to the intelligent gateway through the parent node device, and the parent node device is configured to forward a heartbeat packet receiving instruction fed back by the intelligent gateway to the child node device; the method further comprises the following steps:
and when the child node equipment is normally connected with the father node equipment within the preset time and does not receive the heartbeat packet receiving instruction, marking the child node equipment as offline equipment.
Specifically, the intelligent gateway and the online device in this embodiment maintain a bidirectional heartbeat mechanism, that is, the intelligent gateway receives the heartbeat packet sent by the device and also feeds back a heartbeat packet receiving instruction that has received the heartbeat packet reported by the device. It can be understood that, the heartbeat packet receiving instruction corresponds to the heartbeat packets reported by the online devices one to one, for example, a heartbeat packet is reported by the online device 1 once, and when the intelligent gateway receives the heartbeat packet reported by the online device 1, the intelligent gateway feeds back the corresponding heartbeat packet receiving instruction to the online device 1; the online device 2 reports a heartbeat packet, and the intelligent gateway feeds back a corresponding heartbeat packet receiving instruction to the online device 2 when receiving the heartbeat packet reported by the online device 2; and other devices are analogized in the same way, and are not described in detail. In addition, in this embodiment, the child node device determines, through a neighbor discovery protocol, whether the parent node device and the child node device can also communicate normally.
When discovering that the heartbeat packet fed back by the intelligent gateway is not received by the child node device, the child node device can judge whether the connection between the child node device and the parent node device is normal or not through a neighbor discovery protocol, and still report the heartbeat packet of the child node device at a certain period, for example, once every 30 seconds. However, when the child node device determines that the child node device is normally connected to the parent node device through the neighbor discovery protocol within a certain preset time, for example, within five minutes, but the heartbeat packet fed back by the intelligent gateway is still not received within five minutes, at this time, in the network, the parent node device is actually in a dropped state, and the child node device reconnects the parent node device waiting for the dropped state within the preset time, so that the network connection can be restored only by the parent node device realizing network reconnection once. If the father node device still cannot rejoin the network within the preset time, and the child node device still cannot receive the heartbeat packet fed back by the intelligent gateway and receives the instruction, the child node device determines that the child node device is the offline device.
In one embodiment, when the connection between the child node device and the parent node is abnormal, the child node device is marked as a disconnected device.
Specifically, in this embodiment, the child node device discovers that it is abnormally connected to the parent node device through the neighbor discovery protocol, and meanwhile, the child node device cannot receive a heartbeat packet received by the instruction fed back by the intelligent gateway, that is, determines itself as the offline device.
In one embodiment, when online equipment directly connected with the intelligent gateway does not receive a heartbeat packet fed back by the intelligent gateway, the online equipment is marked as offline equipment.
Specifically, the online device directly connected to the intelligent gateway in this embodiment may also discover that the connection between the online device and the intelligent gateway is abnormal through a neighbor discovery protocol, and then determine that the online device is a dropped device.
It should be noted that, when both the parent node device and the child node device mounted thereon are offline devices, the parent node device preferentially performs network connection restoration, and the original network (i.e., the network connection relationship between the parent node device and the child node device) remains unchanged. Compared with the time that the father node device determines that the son node device is the offline device, the time that the son node device determines that the son node device is the offline device is longer, and after one father node device is prevented from being offline, the plurality of son node devices mounted on the father node device also use the son node device as the offline device and start network connection repair at the same time, so that the pressure of network connection repair is increased, and the network repair efficiency is influenced.
As another embodiment, when the child node device determines that the network connection of the child node device is abnormal, it determines whether the connection abnormality is caused by abnormal connection with a neighbor node of the child node device or due to abnormal connection with a non-neighbor node (remote node), and if the connection abnormality is caused by the abnormal connection of the neighbor node, immediately sends out a drop broadcast signal; if the connection is abnormal due to the connection of a non-neighbor node (a remote node), the heartbeat packet is tried to be reported at a certain frequency (for example, 30 s) once, if the heartbeat packet receiving instruction cannot be received within a second preset time (for example, 5 minutes), the heartbeat packet is determined to be the offline device, and an offline broadcast signal is sent out, and if the heartbeat packet receiving instruction is received within the second preset time, the offline broadcast signal does not need to be sent out, and the heartbeat packet is operated according to normal equipment.
In one embodiment, the online device includes a parent node device and a child node device, the child node device is directly connected to the parent node device and is connected to the intelligent gateway via the parent node device, and the method further includes the steps of:
and acquiring the real-time communication strength of the child node equipment and the parent node equipment, and when the real-time communication strength is smaller than a threshold value, marking the current online equipment as offline equipment.
Specifically, in this embodiment, after the dropped device establishes a connection with the target online device to rejoin the network, the original dropped device is switched to be the child node device, the connected target online device is switched to be the parent node device, and the parent node device proxies and forwards information of the child node device. In this embodiment, whether the child node device is disconnected or not is further determined by monitoring the real-time communication strength between the child node device and the parent node device. Even if the child node device can still receive the heartbeat packet fed back by the intelligent gateway and receives the instruction, the child node device disconnects the connection with the father node device due to the fact that the connection signal is very weak, and rebroadcasts the heartbeat packet so that the on-line device can scan and reestablish the connection with the parent node device, and the problem that a network is unstable due to the fact that the network connection is weak is solved. All online devices participate in scanning, and parent node devices with real-time communication strength lower than a threshold value are not eliminated. Therefore, the misjudgment risk of the real-time communication strength between the parent node device and the child node device in the embodiment due to interference of other factors is reduced.
In one embodiment, as shown in fig. 6, a flowchart of a method for repairing a network connection is provided, and the method is applied to a dropped device and includes steps S190 to S200.
Step S190, sending a broadcast signal, where the broadcast signal is used to inform the online device that there is an offline device in the range of the scanned signal when the online device scans.
Specifically, the broadcast signal in the present embodiment may be, but is not limited to, at least one of a WIFI broadcast signal, a ZigBee broadcast signal, and a BLE broadcast signal. Because the BLE module is widely arranged in each online device, the BLE module is specifically used for generating the broadcast signal in this embodiment, and the broadcast signal is used for informing that the online device has a device with abnormal network connection in the scanning signal range.
When the heartbeat packet fed back by the intelligent gateway equipment cannot be received in the online equipment, the online equipment is determined to be the offline equipment, and the BLE module is started to send a broadcast signal with abnormal network connection to the periphery. In addition, as described above, when the current device is a child node device that is re-networked, and when the child node device monitors that the real-time communication strength between the parent node devices connected to the child node device is lower than the threshold, the child node device also disconnects the parent node device connected to the child node device, and determines that the child node device is a dropped device and starts the BLE module to transmit a broadcast signal with abnormal network connection to the surroundings. That is, in the foregoing embodiment, in a scenario where the online device is marked as a dropped device, the dropped device may generate and send a broadcast signal, which is not described herein again.
And step S200, receiving a connection request sent by the online equipment, and responding to the connection request to establish connection with the online equipment.
The offline device of this embodiment transmits a broadcast signal, so that the peripheral online devices can obtain the address of the offline device and reestablish a connection with the offline device.

The definition of the intelligent gateway is as defined above in the network connection repairing method, and is only briefly described here. When finding that the WIFI equipment 2 is disconnected, the intelligent gateway generates a scanning instruction to indicate all online equipment, including the WIFI equipment 1, the ZigBee equipment 2, the ZigBee equipment 3, the ZigBee equipment 4, the BLE equipment 1, the BLE equipment 2 and the like, and starts a BLE module to scan the periphery; meanwhile, when the WIFI device 2 which is disconnected, the BLE module is started to send a broadcast signal to inform the online device that the disconnected device exists in a scanning signal range; the intelligent gateway receives the scanning result fed back by the online equipment, selects the WIFI equipment 1 as target online equipment according to the scanning result, and generates support information to indicate the WIFI equipment 1 to be connected with the WIFI equipment 2.
Similarly, when the ZigBee device 2 and the ZigBee device 3 are abnormally connected, the ZigBee device 3 generates a broadcast signal, and the intelligent gateway instructs the WIFI device 1 which scans the ZigBee device 3 and has the strongest broadcast signal to connect with the ZigBee device 3.

Taking the network connection repair system in the above embodiment as an example, when the BLE device 1 does not receive the heartbeat packet fed back by the intelligent gateway, the heartbeat packet is marked as an offline device; or when the BLE equipment 2 judges that the connection between the BLE equipment 2 and the BLE equipment 1 is normal within the preset time through a neighbor discovery protocol, but a heartbeat packet which is not fed back by the intelligent gateway is not received, the heartbeat packet is marked as offline equipment; or when the ZigBee device 3 judges that the connection between the ZigBee device 3 and the ZigBee device 2 is abnormal through a neighbor discovery protocol, the connection is marked as a disconnected device.
Step S190, the offline device sends a broadcast signal, where the broadcast signal is used to inform the online device that the offline device exists in the scanning signal range when the online device scans.
Step S110, when the offline device exists, the intelligent gateway generates a scanning instruction to instruct each online device to scan.
Step S160, the online device receives the scanning instruction sent by the intelligent gateway.
And step S170, the online equipment responds to the scanning instruction to scan the offline equipment in the signal range, generate a scanning result and send the scanning result to the intelligent gateway.

Step S132, the intelligent gateway acquires the addresses of the target online devices, and generates the support instruction by using the addresses of the various offline devices and the addresses of the target online devices corresponding to the various offline devices as support information.
Step S180, when receiving a support instruction which is generated by the intelligent gateway according to the scanning result and carries support information, the online equipment is used as target online equipment to send a connection request to corresponding target offline equipment to establish connection, and the support information comprises a corresponding relation between the target online equipment and at least one offline equipment.
Step S200, the offline device receives the connection request sent by the online device, and responds to the connection request to establish connection with the online device.
