In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the subject matter of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth.

The ZigBee technology is a wireless communication technology applied to short distance and low speed, and is mainly used for data transmission between various electronic devices with short distance, low power consumption and low transmission speed, and typical applications of periodic data, intermittent data and low reaction time data transmission. Due to the uniqueness of the ZigBee technology, the ZigBee technology is more and more commonly applied in the communication field.
Fig. 1 is a schematic diagram of a ZigBee network system. As shown in fig. 1, the ZigBee network system includes three kinds of nodes, i.e., a Coordinator (Coordinator)110, a routing node (Router)120, and an End node (End Device) 130.
Wherein the coordinator 110 may be integrated in the gateway. The Gateway (Gateway) is also called an internetwork connector and a protocol converter. The gateway realizes network interconnection above a network layer, is a complex network interconnection device and is only used for interconnection of two networks with different high-level protocols. Instead of the bridge simply communicating the information, the gateway repackages the received information to accommodate the needs of the destination system.
The coordinator 110 is a convergence point of information of each node in the ZigBee network system, is a core node of the network, and is responsible for building, maintaining, and managing the ZigBee network. The coordinator is also a main node in the ZigBee network, and only one coordinator in one ZigBee network manages other nodes in the network.
The routing node 120 is responsible for forwarding data packets, performing routing path finding and routing maintenance of data, allowing the node to join the network and assisting the communication of its child nodes; the routing node is a relay of the end node and the coordinator.
The end node 130 may be directly communicatively coupled to the coordinator 110 or may be communicatively coupled to the coordinator 110 via the routing node 120. The terminal node 130 may be a computer, a mobile phone, an intelligent printer, an intelligent fax machine, an intelligent camera, an intelligent air conditioner, an intelligent door lock, a human body sensor equipped with a communication module (e.g., a ZigBee module, a Wi-Fi module, a bluetooth module, etc.), a door and window sensor, a temperature and humidity sensor, a water sensor, a natural gas alarm, a smoke alarm, a wall switch, a wall socket, a wireless switch wireless wall switch, a magic cube controller, a curtain motor, etc., which are not limited herein.
In a specific embodiment, the step of establishing a complete ZigBee network comprises two steps: network initialization and nodes (end node 130, routing node 120) join the network. The method comprises the following steps that initialization of the ZigBee network can only be initiated by a coordinator, in the initialization process, the coordinator firstly scans channels and determines channels for communication of equipment in the ZigBee network; then the coordinator selects a network identifier (PAN ID, the value of which is less than or equal to 0x3FFF) for the ZigBee network; the initialization of the ZigBee network is realized through the two steps. There are two address modes in a ZigBee network: an extended address (64 bits) and a short address (16 bits), so that the network identifier selected by the coordinator is identified by a PAN (Personal Area network) ID if it is identified by a short address, and by an EXPAN (extended PAN) ID if it is identified by an extended address. It will be appreciated that in particular embodiments, both PAN ID and EXPAN ID may be used to identify the same ZigBee network.
If a node wants to join the ZigBee network, the node sends a correlation request command to the coordinator after scanning to obtain the relevant information of the coordinator, and after receiving the correlation request command sent by the node, the coordinator allocates a short address to the node if agreeing to join the ZigBee network, generates an association response command (Association response command) and returns the association response command to the node.
As described above, in the ZigBee network, the network information of the ZigBee network is maintained by the coordinator, wherein the network information may include various parameters as shown in table 1 below:
TABLE 1
The channel is used for indicating a channel where the ZigBee network is located, namely the coordinator performs channel scanning in the above, and the channel is a channel identifier of a channel determined by the ZigBee network; panid refers to a 16-bit short address of the ZigBee network; expanid refers to a 64-bit extended address of the ZigBee network; the outfc (outlying frame counter) refers to an output frame count value of the coordinator, and the output frame count value is included in the auxiliary header as a means for preventing replay attack. All devices have their own output frame count values that are used to maintain a list of neighbor and sub-frame counters. Each time a device sends a packet, it increments its output frame count value. The receiving device verifies whether the frame count value of the transmitting device has been incremented from the last value it sees. If it is not increased, the packet will be silently discarded. If the receiving device is not the final destination, the data packet including the frame count value of the routing device is decrypted and modified, then the data packet is re-encrypted and sent to the next hop; mac address refers to the physical address of the coordinator; nwk key (network key) refers to a network key, which is a key used by each device in the network for data encryption; key sequence Number (key sequence Number) and key type are two kinds of attributes of the network key; key seqNum refers to the serial number of the network key; the key type refers to the type of the network key; the child table refers to a list of all child devices in the network, which are the above-mentioned device of the terminal node and the device of the routing node.
In addition, the gateway can also establish network connection with the server side. The server may be one server, a server cluster composed of a plurality of servers, or even a cloud computing center composed of a plurality of servers, which is not limited herein. The server refers to an electronic device that provides a background service for a user, for example, the background service includes a monitoring service of a coordinator.
In the ZigBee network, network information is generally stored in a flash memory (flash) of the coordinator chip, but when the coordinator chip voltage is unstable or abnormally restarted, the network information stored in the flash memory of the coordinator chip may be lost, thereby causing the network information read from the flash memory of the coordinator chip to be erroneous or not read from the flash memory of the coordinator chip after the coordinator chip is restarted. In this case, since the network information read by the coordinator is different from the actual network information in the ZigBee network, the coordinator cannot communicate with the devices in the ZigBee network, and the device data in the ZigBee network cannot be reported to the cloud, so that the devices in the ZigBee network are in an offline state.
All the devices in the ZigBee network have the same network key in the same channel and the same domain network address, in other words, all the devices in the ZigBee network have the same set of network information, and if the network information of a certain device changes, the device cannot perform data interaction with other devices in the original network.
For the offline device, if the offline device is to be restored to the online state, the offline device is added to the new ZigBee network created by the coordinator again by adopting factory restoration settings. However, after the factory setting is restored, the configuration information of the equipment itself is lost, and reconfiguration is required to enable all the equipment to reach the normal working state before abnormality, and the process is large in processing workload, high in labor cost and low in efficiency.
In order to solve the problem, the scheme of the application is provided, by backing up the network information in the coordinator, and when the network information in the coordinator is abnormal, restoring the network information in the coordinator based on the backed-up network information.
The following describes in detail a method, an apparatus, an electronic device, and a computer-readable storage medium for recovering network information in a gateway according to embodiments of the present application.
Fig. 2 is a flowchart illustrating a method for recovering network information in a gateway, which is applied to a master control module according to an embodiment of the present application. The method specifically comprises the following steps:
The main control module of the gateway is a core component of a mainboard of the gateway, is a bridge between other modules in the gateway and is also a brain for controlling the running work of the gateway. In some embodiments, a proxy process is provided in the master control module of the gateway to recover the network information in the coordinator according to the method of the present application. In other words, the proxy process refers to a process in the master control module of the gateway for recovering the network information in the coordinator. In other embodiments, the agent process may be disposed in other modules, and is not limited herein.
The backup network information refers to network information which is backed up to the main control module by the coordinator in a normal network state. In some embodiments, a master control flash memory is provided in the master control module, and the master control flash memory is used for storing backup network information.
It should be noted that the backup network information in the main control module is the backed-up network information, that is, when the network information in the coordinator is normal, the network information in the coordinator is backed up to the main control module to serve as a data base for recovering the network information. Compared with the storage space of the coordinator, the storage space of the master control module is larger, and generally, the storage space of the flash memory of the coordinator is at a level of K (1024bytes), and the storage space of the master control module is at a level of M (1M ═ 1024K), so that the storage space occupied by the network information backed up in the master control module is very small, and further, the network information backup in the master control module hardly affects the normal operation of the master control.
In some embodiments of the present application, the query condition of the network information is preset, so that, before step 210, the method further includes: and detecting whether the query condition of the network information is met, and if the query condition is met, executing the step of acquiring the current network information from the coordinator. Otherwise, if the query condition is not met, continuously detecting whether the query condition of the network information is met.
The query condition of the network information can be set according to actual needs. For example, the query condition of the network information may be that the main control module delays for a third set time period after being started, so that, after the main control module is started, if the delay time period reaches the third set time period, step 210 and step 220 are executed. The third set time period may be set according to actual needs, for example, 1 minute, 2 minutes, and the like.
In some embodiments, the query condition of the network information may also be that after the master control module is started, the current time of the master control module is within a set query time period, and the set query time period may be set as needed, for example, the query time period is set to a time period from 3 to 4 points in the early morning of each day. In a specific embodiment, a certain time point or certain time points within the set query time period may be further designated as query time points, and when the main control module detects that the current time is the query time point, it is determined that the query condition of the network information is reached. In some embodiments, a randomly selected time point within the query time period may also be set as the query time point.
The nodes in the ZigBee network change along with the time extension, for example, a new node is added into the ZigBee network or the node exits from the ZigBee network, a sub-device list is maintained in the coordinator, the sub-device list indicates devices added into the ZigBee network, the addition of the new node into the ZigBee network corresponds to the new addition of a device identifier in the sub-device list, and the exit of the node from the ZigBee network corresponds to the deletion of the device identifier in the sub-device list.
In some embodiments, the query condition of the network information may also be that the list of the child devices is updated, and the update may be that the device identifier is deleted or that the device identifier is newly added. Therefore, before step 210, the agent process acquires the sub device list from the coordinator, compares the currently acquired sub device list with the sub device list acquired last time, and determines that the query condition of the network information is satisfied if it is determined through the comparison that the currently acquired sub device list is different from the sub device list acquired last time.
In some embodiments, the network information query condition may also be that the output frame count value is updated, and the update may be that the output frame count value becomes larger or smaller. Accordingly, the output frame count value is acquired from the coordinator, the currently acquired output frame count value is compared with the last acquired output frame count value, and if it is determined through the comparison that the currently acquired output frame count value is different from the last acquired output frame count value, it is determined that the query condition of the network information is satisfied.
In some embodiments of the present application, the network information backup condition may also be that it is detected that the sub-device list and the output frame count value are updated at the same time, and if it is detected that the sub-device list and the output frame count value of the network information in the coordinator are updated at the same time, it is determined that the network information backup condition is satisfied.
In some embodiments, since when a new device joins the ZigBee network, the coordinator needs to send an association response command to the device, the association response command indicating that the device is allowed to join the ZigBee network; if one device exits from the ZigBee network, the coordinator is required to send a disconnection command to the device or the device sends a disconnection command to the coordinator, and the disconnection command is used for indicating the coordinator to be separated from the device, namely the device exits from the ZigBee network, so that whether a new device is added in the ZigBee network can be determined by monitoring whether the coordinator sends a correlation response command; whether a device exits in the ZigBee network may be determined by monitoring whether the coordinator transmits a disconnection command or receives a disconnection command. In some embodiments, the query condition of the network information may also be that the coordinator is monitored to send an association response command, the coordinator sends a disconnection command, or the coordinator receives a disconnection command, so that if the coordinator is monitored to meet one of the above three conditions, the query condition of the network information is determined to be reached.
In some embodiments, the query condition of the network information may also be a delay of a second set time period after confirming that the device is newly added to the ZigBee network or deleted (i.e., the device exits the ZigBee network), so that the steps 210 and 220 are performed after the delay of the second set time period after confirming that the device is newly added to the ZigBee network or deleted. Similarly, the second set time period may be set as required, for example, 3 minutes, 5 minutes, etc., and is not particularly limited herein.
And 240, if the current network state of the characterization coordinator is different, sending backup network information to the coordinator to replace the network information so as to restore the network state of the coordinator to a normal state.
As described above, the network information includes a plurality of parameters, as shown in table 1 above. In some embodiments, parameter types may be set for various parameters, for example, the parameter types include a first parameter type and a second parameter type, where, in the parameters shown in table 1, a parameter whose parameter type is the first parameter type may refer to a parameter that may be updated in real time, but does not cause network information to be abnormal after being updated. For example, the parameter of which the parameter type is the first parameter type may be the key frame count value and the sub device list in table 1. The parameter with the parameter type of the second parameter type may refer to a parameter that may cause network traffic abnormality after being changed, for example, channel (channel identifier), panid, expanid, mac address, nwk key, key seqNum, and the like in table 1.
After the network information is acquired from the coordinator and the backup network information is acquired from the main control module, the parameters are respectively compared, so that parameters (which may be called as difference parameters for convenience of distinguishing) different from parameters in the backup network information in the network information acquired from the coordinator are determined.
Then, the parameter type to which the difference parameter belongs is determined, i.e. whether the difference parameter belongs to the first parameter type or the second parameter type is determined. In some embodiments, in step 240, if it is determined that the difference parameter belongs to the second parameter type, the network information recovery is triggered, that is, "sending the backup network information to the coordinator to replace the network information so as to recover the network state of the coordinator to the normal state" in step 240 is executed; otherwise, if it is determined that the difference parameter belongs to the first parameter type, the network information recovery may not be triggered, that is, the step 240 of sending the backup network information to the coordinator to replace the network information so as to recover the network state of the coordinator to the normal state is not executed, and at this time, only the difference parameter belonging to the first parameter type is backed up to the main control module so as to update the corresponding parameter in the main control module.
And because the backup network information in the main control module is the backed-up network information and is accurate network information, the backup network information in the main control module is written into the coordinator to replace the network information in the coordinator, so that the network information in the coordinator is restored.
In a specific embodiment, the master control module may write the backup network information acquired from the master control module into the coordinator through an interface of the coordinator, so as to replace the abnormal network information in the coordinator.
According to the scheme, the network information is backed up in the main control module, and under the condition that the network information in the coordinator is determined to be different from the backup network information in the main control module and the difference parameter belongs to the second parameter type, the network information in the coordinator is recovered based on the backup network information in the main control module so as to replace abnormal network information in the coordinator, so that the problem that other equipment in the network cannot communicate with the coordinator due to the abnormal network information in the coordinator can be effectively solved, and the abnormal network information can be timely recovered when the network information in the coordinator is abnormal.
In addition, in the scheme, when the master control module detects that the network information in the coordinator is different from the backup network information in the master control flash memory, the backup network information in the master control module is automatically restored to the coordinator, the process is automatically carried out in the gateway device, the situation that the sub-device is offline is avoided, and the non-inductive restoration of the network information is realized. For the user, the device is always normal; an engineer can query the gateway log to know the abnormal recovery condition of the coordinator. Therefore, the scheme can effectively solve the problem of network information abnormity and timely, efficiently and automatically recover and restore the network information.
In the prior art, due to the abnormal network information in the coordinator, other devices in the network are in an offline state. However, after the factory setting is restored, the configuration information of the device itself is lost, and it is necessary to reconfigure all the devices to a normal working state before an abnormality, which results in a large processing workload, high labor cost, and low efficiency. In the scheme, because the abnormal network information in the coordinator is restored in time according to the backup network information in the main control module, the equipment does not need to be restored to factory settings, reconfigured and the like, and only the network information in the coordinator is restored, so that the processing workload is greatly reduced, and the restoration efficiency is improved.
In the prior art, network information in the coordinator generally has an abnormality due to unstable voltage of the coordinator chip or abnormal restart of the coordinator chip, and in the present solution, the network information is not backed up to other places in the coordinator but is backed up to the main control module outside the coordinator, so that the unstable voltage of the coordinator chip or the restart of the coordinator chip does not affect the network information in the main control module, and therefore, it can be ensured that the network information restored to the coordinator is accurate network information, and the coordinator can perform normal communication with other devices after the network information in the coordinator is effectively restored.
Fig. 3 is a flowchart illustrating steps before step 220 according to an embodiment of the present application, and as shown in fig. 3, before step 220, the method further includes:
In step 320, if the backup condition is satisfied, the network information is backed up.
In some embodiments of the present application, the backup condition of the network information may be a delay of a first set time period after the master control module is started, where the first set time period may be set according to actual needs, for example, set to 30 seconds, 45 seconds, and the like. It is understood that the first set period of time is less than the third set period of time. Of course, the first set time period may be equal to the third set time period.
In some embodiments of the present application, the backup condition of the network information may also be that after the master control module is started, the current time of the master control module is within a set backup time period, and the set backup time period may be set according to needs, for example, the backup time period is set to a time period from 2 to 3 points in the morning every day. In a specific embodiment, one or more backup time points may be further specified within the set backup time period, and when the current time reaches the backup time point, it is determined that the backup condition of the network information is satisfied. In other embodiments, a randomly selected time point within the backup time period may be set as the backup time point.
In some embodiments of the present application, the backup condition of the network information may also be that a sub-device information update in the network information in the coordinator is detected, and if a sub-device list update of the network information in the coordinator is detected (for example, a sub-device list currently acquired from the coordinator), it is determined that the backup condition of the network information is satisfied.
In some embodiments of the present application, the backup condition of the network information may be further that the output frame count value is detected to be updated, and the updating may be that the output frame count value becomes larger or smaller. Accordingly, the output frame count value is acquired from the coordinator, the currently acquired output frame count value is compared with the last acquired output frame count value, and if it is determined through the comparison that the currently acquired output frame count value is different from the last acquired output frame count value, it is determined that the backup condition of the network information is satisfied.
In some embodiments of the present application, the network information backup condition may also be that it is detected that the sub-device information and the output frame count value are updated at the same time, and if it is detected that the sub-device list of the network information and the output frame count value in the coordinator are updated at the same time, it is determined that the network information backup condition is satisfied.
In some embodiments of the present application, the backup condition of the network information may also be that a fourth set time length is delayed after the coordinator sends an association response command, the coordinator sends a disconnection command, or the coordinator receives the disconnection command, and the fourth set time length may be used for the coordinator to update the list of the child devices in the network information. And if the delay time after the coordinator sends the association response command, the coordinator sends the disconnection command or the coordinator receives the disconnection command reaches the fourth set time after monitoring, determining that the backup condition of the network information is met.
Of course, the backup conditions of the network information listed above are only exemplary examples and should not be considered as limiting the scope of application of the present application.
In some embodiments, step 320 further comprises: detecting whether backup network information exists in the main control module; if the backup network information exists, updating the sub-equipment list and the output frame count value in the backup network information according to the sub-equipment list and the output frame count value in the network information; if not, the network information is completely backed up to the main control module.
In this embodiment, if it is detected that the backup network information exists in the main control module, it indicates that at least one network information backup is performed in the main control module, and in the same ZigBee network, information such as a channel (channel), a network identifier (PAN ID, expanid), and a MAC Address (MAC Address) in the network information is kept unchanged, and what may be changed is a sub-device list and an output frame count value in the network information. Therefore, when the backup network information exists in the main control module, only the sub-device list and the output frame count value in the network information in the coordinator can be backed up in the main control module, that is, only the sub-device list and the output frame count value in the backup network information in the main control module are updated, and other parameters are not updated.
On the contrary, if it is detected that the backup network information does not exist in the main control module, it indicates that the network information has not been backed up in the main control module, and therefore, in this case, the first network information is completely backed up in the main control module. In the subsequent process, only part of parameters in the network information can be updated based on the network information which is backed up in the main control module.
In summary, in this embodiment, after the network information backup is performed in the main control module for the first time, all subsequent backups use the network information of the first backup as a reference (it can be understood that the network information of the first backup is network information obtained by the coordinator creating the ZigBee network), only the child device list (child table) and the output frame counter (outgoing frame counter) are updated, and other parameters are not updated. Compared with the method for updating all the network information in the main control module, the method only updates the sub-device list and the output frame count value, greatly reduces the data updating amount, shortens the backup time, and improves the network information backup rate and efficiency.
Fig. 4 is a flowchart illustrating steps after step 240 according to an embodiment of the present application, and as shown in fig. 4, after step 240, the method further includes:
In some embodiments, after the proxy process restores the backup network information in the master control module to the coordinator, the gateway master may pull down a reset (reset) pin in the coordinator to implement hardware reset of the coordinator. By performing a reset operation on the coordinator, the coordinator can read the network information from its own flash memory and report the read network information to the gateway. It is to be understood that, in this step, since the coordinator is reset after the network information in the coordinator is restored, if the network information is successfully restored, the network information read from the flash memory of the coordinator is the network information restored in the coordinator.
In step 420, comparing the parameter value of each parameter in the first network information reported by the coordinator with the parameter value of the corresponding parameter in the backup network information in the main control module one by one, and if the parameter value of each parameter in the first network information reported by the coordinator is the same as the parameter value of the corresponding parameter in the backup network information in the main control module, confirming that the two network information are the same, thereby indicating that the network information in the coordinator is successfully restored; on the contrary, if the parameter value of at least one parameter in the first network information reported by the coordinator is different from the parameter value of the corresponding parameter in the backup network information in the main control module, the two pieces of network information are determined to be different, and then the network information recovery failure in the coordinator is indicated.
And in case that the recovery of the network information in the coordinator is determined to fail, the step 240 is carried out, and the step of recovering the backup network information in the gateway main control module to the coordinator is repeatedly carried out.

step 510, the coordinator reports the current network information.
And step 520, if the agent process detects that the network information reported by the agent process is abnormal, performing network information recovery operation on the coordinator, and controlling the gateway master control to perform hardware reset on the coordinator.
And after receiving the network information reported by the coordinator, the agent process reads the backup network information from the main control module so as to judge whether the network information in the coordinator is abnormal. If the abnormal condition exists, the network information recovery operation is performed on the coordinator, and the process of the network information recovery operation refers to the above description, which is not described herein again.
Step 530, the coordinator reports the network information again after resetting.
And 540, the agent process confirms whether the network information in the coordinator is successfully recovered, and if the network information in the coordinator is not successfully recovered, the agent process performs network information recovery operation on the coordinator again. And if the backup network information is unsuccessful, writing the backup network information in the main control module into the coordinator again.
In some embodiments of the present application, in order to improve efficiency, a threshold of the number of times that the coordinator repeatedly performs the network information recovery operation may be further set, and if the number of times that the coordinator continuously performs the network information recovery operation reaches the threshold of the number of times, the coordinator is stopped from performing the network information recovery operation again (that is, the step 240 is stopped from being performed again), and fault information is reported to the server, where the fault information is used to indicate that the network information in the coordinator is abnormal. Fig. 6 is a flowchart illustrating a method for recovering network information in a gateway according to an embodiment of the present application, in this embodiment, a main control module is provided with a main control flash memory, and the main control flash memory is used for storing backup network information, and as shown in fig. 6, the method includes:
And step 640, performing network information recovery operation on the coordinator, and adding 1 to the recovery frequency accumulation.
