Data processing method, device and network system

Technical Field

The invention belongs to the field of communication networks, and particularly relates to a data processing method, a data processing device and a network system.

Background

The existing ZigBee wireless short-distance communication system generally comprises a coordinator, a router and terminal equipment. Generally, a ZigBee wireless short-distance communication system is composed of a coordinator, a plurality of routers, and a plurality of terminal devices, wherein networking information generated by the coordinator, the routers, and the terminal devices after networking is stored in a Non-Volatile memory (NVRAM) of each device, and the networking information includes a connection relationship between the routers and the coordinator, a connection relationship between the terminal devices and the coordinator, a connection relationship between the coordinator and the connected routers, and other connection relationships between the devices connected to each device.

Taking a router as an example, after the existing router and the coordinator are connected, network pairing is completed between the router and the coordinator, that is, the connection relationship between the router and the coordinator is bound, and when the router is disconnected from the coordinator, the router cannot be connected with other coordinators. Therefore, in the existing ZigBee network, when the coordinator fails and the connection between the router and the coordinator is disconnected, the router cannot be connected to the network any more, and the reliability of the ZigBee network is reduced.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, fig. 1 shows a network system 10, which includes: coordinator 100, router 200, terminal device 300, and gateway 400.

The coordinator 100 is a main controller of the entire network, and the coordinator 100 is responsible for establishing an entire network system, transmitting network beacons, managing nodes in the network (for example, the router 200 connected to the coordinator 100), storing network node information, finding routing information among the nodes, and continuously receiving data transmitted by the router 200, the terminal device 300, and the gateway 400, and each network has only one coordinator.

The router 200 is a routing device supporting concatenation, and the router 200 allows other devices to join a network in which the router is located through the router, and can implement a message forwarding function between nodes. There may be multiple routers in a network. When a connection pair is established between the router 200 and the coordinator 100 in the network system 10, that is, the router 200 stores connection information of the coordinator 100, where the connection information is used to indicate a connection relationship between the router 200 and the coordinator 100, for example, the connection information may be an ID of the coordinator 100 or an association table between the coordinator 100 and the router 200.

When the router establishes connection with the coordinator, the router stores the connection information of the connected coordinator, and the storage mode at least comprises two modes: in memory and in NVRAM. When the router is to be paired with the coordinator connected to the router, the connection relationship between the router and the coordinator connected to the router is bound, and the connection information of the coordinator is written into the NVRAM. The information stored in the memory can be automatically emptied when the router is powered down. And the connection relationship between the router and the coordinator stored in the memory is not a binding relationship, and at this time, the router can still try to establish connection with other coordinators.

When the router 200 establishes a connection with the coordinator 100, it actively reports the ID of the router. Preferably, the router 200 and the coordinator 100 agree on a protocol, the router 200 reports the ID of the router 200 according to a format prescribed by the protocol, and the coordinator 100 receives the ID sent by the router 200 according to the protocol. For example, the data transmission format agreed between the router 200 and the coordinator 100 is as follows:

unsigned char data[8]；

data[0]＝0xAA；

data[1]＝0x55；

data[2]＝4；//length

data[3]＝ROUTER_ID_REPORT；//type

data[4]～data[7]＝RouterId；

in this embodiment, the connection between the router 200 and the coordinator 100 may refer to the direct connection between the router 200 and the coordinator 100, or the connection between the router 200 and the coordinator 100 through another router may also refer to the connection between the router 200 and the coordinator 100, that is, the connection between the router 200 and the coordinator 100 indicates that the router 200 is added to the network in which the coordinator 100 is located.

The terminal device 300 is used to implement a specific function, and the terminal device 300 is connected to other devices with which communication is required through a network in the network system 10. Similarly, when the terminal device 300 establishes a connection with the coordinator 100, the ID of the terminal device 300 is actively reported. Preferably, the terminal device 300 and the coordinator 100 define a protocol, the terminal device 300 reports the ID of the terminal device 300 according to a format defined by the protocol, and the coordinator 100 receives the ID sent by the terminal device 300 according to the protocol. For example, the data transmission format agreed between the terminal device 300 and the coordinator 100 is as follows:

unsigned char data[8]；

data[0]＝0xAA；

data[1]＝0x55；

data[2]＝4；//length

data[3]＝END_DEVICE_ID_REPORT；//type

data[4]～data[7]＝deviceId；

the gateway 400 is used to implement connection between the coordinator 100 and the internet, and the gateway 400 may be an internet communication module, such as a wifi gateway, and when the communication connection between the coordinator 100 and the gateway 400 is normal and the connection between the gateway 400 and the internet is normal, the coordinator 100, the router 200, and the terminal device 300 not only can form a wireless local area network, but also can be connected to the internet through the gateway 400.

In this embodiment, the router 200 is a ZigBee router, and the network system 10 is a ZigBee wireless network system.

Referring to fig. 2, fig. 2 shows a network system 10 applied to an intelligent door lock system, wherein the network system 10 includes: a first network subsystem 11 and a second network subsystem 12.

The first network subsystem 11 comprises: a first coordinator 101, a first router 201, a second router 202, a first smart door lock 301, a second smart door lock 302, a third smart door lock 303, and a fourth smart door lock 304.

The first coordinator 101 is the same as the coordinator 100 in fig. 1, and is not described herein again.

The first router 201 and the second router 202 are the same as the router 200 in fig. 1, and are not described herein again. The first router 201 is connected to the first coordinator 101, the second router 202 is connected to the first router 201, and a cascade relationship is formed between the first router 201 and the second router 202.

First intelligent lock 301, second intelligent lock 302, third intelligent lock 303 and fourth intelligent lock 304 are for possessing the network communication function and can control the intelligent equipment that the electronic lock was opened to the opening and closing of the room door that the control corresponds. The fourth intelligent door lock 304 is connected with the first coordinator 101, the first intelligent door lock 301 is connected with the first router 201, and the second intelligent door lock 302 and the third intelligent door lock 303 are both connected with the second router 202.

In this example, the smart door lock includes a ZigBee communication module, and the smart door lock can join the network system through connection with the router, for example, the first smart door lock 301, the second smart door lock 302, and the third smart door lock 303 join the ZigBee network through the router. The smart door lock may also join the network system through a connection with the coordinator, for example, a fourth smart door lock 304 joins the ZigBee network through the first coordinator.

The second network subsystem 12 comprises: a second coordinator 102, a third router 203, and a fifth smart door lock 305. The second coordinator 102 has the same function as the first coordinator 101, the third router 203, the first router 201 and the second router 202 have the same function, and the first intelligent door lock 301, the second intelligent door lock 302, the third intelligent door lock 303, the fourth intelligent door lock 304 and the fifth intelligent door lock 305 have the same function.

After the networking of the first network subsystem 11 and the second network subsystem 12 is completed, a connection pair is established between the third router 203 and the second coordinator 102, that is, the third router stores the connection information of the second coordinator 102. At this time, even if there is the same channel between the first network subsystem 11 and the second network subsystem 12, the third router 203 cannot be connected with the first coordinator 101, and the first router 201 and the second router 202 cannot be connected with the second coordinator 102.

Referring to fig. 4, fig. 4 shows a data processing method according to an embodiment of the present invention, which is applied to the system and the apparatus. The data processing method comprises the following steps:

step S401: monitoring a network connection state with a coordinator;

when the router establishes connection with the coordinator, namely the router joins the network formed by the coordinator, the router sends a piece of data to the coordinator according to the protocol established between the router and the coordinator, wherein the data comprises the ID of the router. After the coordinator receives the data, the data is analyzed according to the protocol, so that the ID of the router is obtained, and the router corresponding to the ID is added into the network formed by the coordinator.

As an embodiment, a data structure is provided in the coordinator, and the data structure is used for storing the IDs of all routers establishing connection with the coordinator and other information, and when the coordinator establishes connection with the routers, the IDs of the routers are stored in the data structure. Wherein the data structure may be a memory space. For example, the data structure is implemented as follows:

similarly, when the router establishes a connection with the coordinator, the router can obtain the ID of the coordinator, specifically, when the router establishes a connection with the coordinator, the router sends an acquisition instruction to the coordinator to instruct the coordinator to send its ID and other information to the router; when the router establishes a connection with the coordinator, the coordinator may obtain the ID transmitted by the router and then transmit the ID of the coordinator to the router. After obtaining the ID of the coordinator, the router obtains connection information of the coordinator, where the connection information of the coordinator is used to indicate identity information of the coordinator connected to the router, and the connection information may be the ID of the coordinator or other information capable of uniquely identifying the coordinator. In this embodiment, preferably, the connection information of the coordinator is an ID of the coordinator.

After the router obtains the ID of the coordinator, it can record the identity of the coordinator connected at this time, and establish the connection relationship between the router and the coordinator, for example, a corresponding table for recording the connection relationship between the router and the connected coordinator may be established in the router. Taking the second coordinator and the third router in fig. 2 as an example, assuming that the ID of the second coordinator is X2 and the ID of the third router is L3, the format of the corresponding table is shown in table 1:

TABLE 1

Router ID	ID of connected coordinator
		L3	X2

Note that, in the second row and second column in table 1, filling X2 with the content corresponding to the ID of the connected coordinator indicates that the third router can only connect to the second coordinator corresponding to X2, that is, once the ID of the coordinator is written in the second row and second column in table 1, the third router can only connect to the coordinator corresponding to the ID in the second row and second column in table 1. When the contents in the second row and the second column in table 1 are empty, indicating that the third router has not established a connection with any coordinator, at this time, the third router automatically reconnects with the searched coordinator.

In the embodiment of the present invention, the content corresponding to the second row and the second column in table 1 is the ID of the coordinator currently stored in the router.

After the router establishes connection with the coordinator, the network connection state with the coordinator is monitored, and the monitoring mode may be:

in the first mode, a heartbeat packet is set in the coordinator, so that the coordinator sends the heartbeat packet to all connected routers at regular time. For example, the coordinator sends a heartbeat packet to a router at every other transmission interval in a round-robin manner, where the heartbeat packet refers to a data packet sent at every other time interval, and the transmission interval is the interval between the sending times of two adjacent heartbeat packets. The format for sending the heartbeat packet is agreed by both the router and the coordinator, and may be:

the router judges whether a heartbeat packet sent by the coordinator is received within a first preset time period, if the heartbeat packet sent by the coordinator is received within the first preset time period, the network connection state with the coordinator is judged to be normally connected, and if the heartbeat packet sent by the coordinator is not received within the first preset time period, the network connection state with the coordinator is judged to be disconnected. The time starting point of the first preset time period may be a time point at which the router last receives the heartbeat packet sent by the coordinator. The above network connection state between the router and the coordinator is normal, which means that the communication connection between the router and the coordinator is not disconnected, and data interaction between the router and the coordinator can be performed through a channel between the router and the coordinator.

It should be noted that, in the embodiment of the present invention, the disconnection of the network connection between the router and the coordinator may be caused by a power failure of the router, a power failure of the coordinator, a failure of a link between the router and the coordinator, and the like.

The step of the router determining whether the heartbeat packet sent by the coordinator is received within the first preset time period may be:

the router receives a heartbeat packet sent by the coordinator at a preset transmission interval, and records the current time as a first time point;

judging whether the heartbeat packet sent by the coordinator is received again within a first preset time period, if the heartbeat packet sent by the coordinator is received again within the first preset time period, judging that the network connection state with the coordinator is normal, and if the heartbeat packet sent by the coordinator is not received again within the first preset time period, judging that the network connection state with the coordinator is disconnected, wherein the starting point of the first preset time period is a first time point.

In addition, the coordinator may detect whether the connected router has been disconnected from the coordinator through the above-described heartbeat packet. The method includes that a coordinator sends a first heartbeat packet to a router, the coordinator records that the current time is a second time point, and after the router receives the first heartbeat packet, a second heartbeat packet needs to be fed back to the coordinator based on the obtained first heartbeat packet. Therefore, when the coordinator receives the second heartbeat packet transmitted by the router, the coordinator determines that the transmitted first heartbeat packet has been successfully received by the router.

Therefore, the coordinator can judge whether the connection between the coordinator and the router is normal by judging whether a second heartbeat packet returned by the router based on the first heartbeat packet is received or not within a second preset time period, if the second heartbeat packet returned by the router based on the first heartbeat packet is received within the second preset time period, the network connection state between the coordinator and the router is judged to be normal, and if the second heartbeat packet returned by the router based on the first heartbeat packet is not received within the second preset time period, the network connection state between the coordinator and the router is judged to be disconnected.

In the second mode, the router sends a second data packet to the coordinator at regular time, and after receiving the second data packet, the coordinator feeds back the first data packet to the router based on the second data packet. And when the router does not receive the first data packet sent by the coordinator based on the second data packet within a first preset time period, judging that the network connection state with the coordinator is disconnection, otherwise, judging that the network connection state with the coordinator is normal connection. And the starting time point of the first preset time period is the time point of sending the second data packet.

As an embodiment, the second packet may be a detection instruction, where the detection instruction is used to instruct the coordinator to send the first packet to the router, and the first packet includes test data agreed by both parties, and when the router receives the first packet, the router analyzes the first packet to obtain the test data, which indicates that the network connection between the coordinator and the router is not disconnected.

Of course, the second data packet may also include one data message, and after receiving the second data packet, the coordinator obtains the data message by analyzing the second data packet, and feeds back the second data packet based on the data message, where the second data packet includes test data generated based on the data message. When the router receives the test data within the first preset time period, the network connection between the coordinator and the router is not disconnected.

The time lengths of the first preset time period and the second preset time period are set by a worker according to an actual application environment.

Step S402: when the coordinator network connection state is disconnection, the router searches other coordinators in a preset range;

the preset range may be the maximum coverage range within which the router can receive the wireless signal, and of course, may also be a signal receiving range smaller than the maximum coverage range, and may be set according to an actual application scenario. The coordinator network connection state refers to a network connection state of the coordinator with the connected device, for example, a connection state with the router. Of course, when the coordinator is powered off, the network connection state of the coordinator is that the network connection between the coordinator and all the devices connected with the coordinator is disconnected.

In this embodiment of the present invention, when the router establishes a connection with the coordinator, the coordinator is not bound to the router, and as an implementation, the connection information of the coordinator is not stored in the NVRAM, and the specific implementation is as follows: receiving a modification instruction; and deleting a preset storage strategy according to the modification instruction, wherein the storage strategy is used for storing the connection information of the coordinator to a nonvolatile memory.

The preset storage policy is a storage policy set by a router, a coordinator, a terminal device or other devices joining the network when the router, the coordinator, the terminal device or other devices leave a factory. The strategy is as follows: after joining the network, the router stores the coordinator ID and other information in the NVRAM, and the coordinator ID is permanently stored in the NVRAM, and is deleted only when the router is restored to a factory value or other operations capable of initializing the NVRAM occur.

The modification instruction may be an operation of a worker on the router, for example, before the router is connected with the coordinator, the worker opens a ZigBee project corresponding to the router, and annotates the macro NV _ RESTORE and the macro NV _ INIT in the Preprocessor configuration in C/C + + Compiler. The annotation is to delete the program statement from the whole program code by writing the program statement into the annotation, so that the router cannot execute the program statement, and thus cannot realize the function corresponding to the program statement. The function implemented by macro NV _ RESTORE and macro NV _ INIT is the storage policy described above.

After the preset storage policy is deleted, the router cannot execute the operation of storing the ID of the coordinator in the NVRAM, or bind the router with the connection relationship of the coordinator stored in the NVRAM. But stores the ID of the coordinator in a memory for temporary storage after obtaining the ID of the coordinator. Therefore, the router and the coordinator are not bound, and the router can establish connection with other coordinators after disconnection from the coordinator.

Thus, when the router is powering down, the coordinator's ID stored in memory is automatically cleared. When the router is powered on again, the router searches other coordinators within the preset range and establishes connection with one coordinator.

And when the connection between the router and the coordinators is disconnected due to the power failure of the coordinators, the failure of the router, the failure of the coordinators or other reasons, and the router is not powered off, the system of the router judges that the network connection with the coordinators is disconnected, and automatically searches for other coordinators within a preset range and establishes connection with one of the coordinators.

Taking the third router and the second coordinator as an example, in the first deletion mode, when the third router is connected to the second coordinator, the third router stores the ID of the second coordinator in the memory of the third router, and the content in the second row and the second column in table 1 is the ID of the coordinator stored in the memory of the third router, that is, the ID — X2 of the second coordinator. When the third router is powered off, the memory is emptied, the ID of the second coordinator stored in the third router is deleted, at this time, the content in the second row and the second column in table 1 is empty, and at this time, the third router is not connected to any coordinator.

When the third router is disconnected from the second coordinator due to the power failure and the fault of the second coordinator, the fault of the third router, and the like, the third router searches for other coordinators within the preset range, establishes connection with one of the coordinators, and replaces the ID of the second coordinator in table 1 with the ID of the newly connected coordinator.

Step S403: the router connects with one of the searched other coordinators.

When the router searches only one coordinator within a preset range, the router is connected with the searched coordinator. When the router searches for a plurality of coordinators within a preset range, the router may select any one of the searched coordinators to establish a connection, or may select a coordinator with the highest signal strength from the searched coordinators to establish a connection. The method for selecting the coordinator with the highest signal strength to establish the connection is as follows: acquiring the searched transmitting signal strength of other coordinators; searching the coordinator with the maximum transmitting signal intensity in the searched other coordinators; and connecting with the coordinator which has the maximum searched transmitting signal strength. The router stores the storage information of the connection information of the connected coordinator in the memory.

Next, taking the third router and the second coordinator in fig. 2 as an example, the method flow corresponding to fig. 4 is described:

after the third router and the second coordinator establish connection, the third router stores the ID of the second coordinator, and in table 1, the ID of the connected coordinator corresponding to the third router is X2. When the third router is disconnected from the second coordinator and does not power down, the third router re-searches for other coordinators within the preset range, the first coordinator is searched, the third router establishes connection with the first coordinator, and the ID of the second coordinator in table 1 is replaced by the ID of the first coordinator, at this time, the ID of the connected coordinator corresponding to the third router in table 1 is X1, where X1 is the ID of the first coordinator. When the third router is disconnected from the second coordinator and the third router is powered off, the ID of the second coordinator stored in the third router is deleted, and in table 1, the ID of the connected coordinator corresponding to the third router is null. After the third router is powered on again, the third router searches for the coordinator within the preset range again, if the first coordinator is found, the third router establishes connection with the first coordinator, and the ID of the connected coordinator corresponding to the third router in table 1 is X1.

The third router joins the network in which the first coordinator is located as shown in fig. 5. In addition, the third router joins the network corresponding to the first coordinator, in which the third router sends a connection request to the first coordinator, the first coordinator regulates and controls the second router to establish connection with the third router, and when the second router is connected with the third router, the third router joins the network corresponding to the first coordinator.

In addition, it should be noted that the main body of the above method may also be the terminal device, that is, when the terminal device is disconnected from the coordinator, the terminal device establishes a connection with another coordinator, specifically, refer to fig. 6. Fig. 6 shows a data processing method according to another embodiment of the present invention, which is applied to the above system and apparatus, and takes a terminal device as an execution subject. The data processing method comprises the following steps:

step S601: the terminal equipment monitors the network connection state with the coordinator.

Step S602: and when the network connection state of the coordinator is disconnected, the terminal equipment searches other coordinators in a preset range.

Step S603: the terminal device connects with one of the searched other coordinators.

Step S604: the terminal device stores connection information of the connected coordinator.

The above steps can be referred to the above method embodiments, and are not described herein again.

When a terminal device, such as the fourth intelligent door lock in fig. 2, is disconnected from the network of the coordinator, the terminal device can attempt to establish a connection with another coordinator, and attempt to join the ZigBee network in which the other coordinator is located.

In addition, a plurality of routers and a coordinator form a sub-network, such as the second router, the first router and the first coordinator form a first sub-network, and the third router and the second coordinator form a second self-network in fig. 2. When the first intelligent door lock, the second intelligent door lock, the third intelligent door lock and the fourth intelligent door lock are connected with the first sub-network, when the first coordinator is powered off, the first router and the second router are disconnected with the first coordinator, the first intelligent door lock, the second intelligent door lock, the third intelligent door lock and the fourth intelligent door lock are disconnected with the first sub-network, and at the moment, the first intelligent door lock, the second intelligent door lock, the third intelligent door lock and the fourth intelligent door lock attempt to join other zigbee networks nearby. For example, if the fourth smart door lock is disconnected from the first coordinator, the fourth smart door lock is disconnected from the first sub-network, and the fourth smart door lock attempts to join the second self-network. Specifically, the fourth intelligent door lock searches all network devices such as routers or coordinators within a certain range, and selects one of the network devices to connect. For example, if the fourth smart door lock searches for the second coordinator and the third router, the fourth smart door lock may connect to the second sub-network through the connection with the third router, or may connect to the second sub-network through the connection with the second coordinator.

Referring to fig. 7, fig. 7 shows a data processing method according to another embodiment of the present invention, which is applied to the system and the apparatus. The data processing method comprises the following steps: step S701 and step S702. The steps included in the method of the present embodiment will be described in detail below with respect to the coordinator as the execution subject.

Step S701: the coordinator obtains and stores information of the connected routers.

When the coordinator establishes a connection with the router, the coordinator can obtain the ID of the router, preferably, when the router is connected with the coordinator, the coordinator actively reports the ID of the router to the coordinator, and the coordinator stores the obtained IDs of all the routers, for example, in a preset data structure.

Step S702: when disconnection from the connected router is detected, the stored information of the router is deleted.

In one embodiment, the coordinator is provided with an association table for recording IDs of routers connected to the coordinator, and taking the first coordinator of fig. 2 as an example, the ID of the first smart door lock is M1, the ID of the second smart door lock is M2, the ID of the third smart door lock is M3, the ID of the fourth smart door lock is M4, the ID of the first router is L1, the ID of the second router is L2, and the ID of the first coordinator is X1. When the coordinator is connected to multiple routers, then the association table may be as shown in table 2:

TABLE 2

ID of first coordinator	ID of connected router	ID of connected intelligent door lock
			X1	L1	M1
	L2	M2
					M3
		M4

Similar to the principle of table 1, in table 2, the content of the column corresponding to the ID of the connected router corresponds to the ID of the router stored by the first coordinator, and the content of the column corresponding to the ID of the connected intelligent door lock corresponds to the ID of the intelligent door lock stored by the first coordinator.

When the first coordinator detects that the connection with the first router is disconnected, the first coordinator deletes the stored ID of the first router. In addition, the first router sends the ID of the connected intelligent door lock to the first coordinator, specifically, a second data packet and a second heartbeat packet in the method flow corresponding to fig. 4 may be used, that is, the second data packet sent by the first router to the first coordinator includes the ID of the intelligent door lock to which the first router is currently connected, or the second heartbeat packet sent by the first router to the first coordinator includes the ID of the intelligent door lock to which the first router is currently connected. Therefore, the first coordinator can obtain the ID of the intelligent door lock connected with the coordinator according to the ID of the intelligent door lock sent by each router, so that which intelligent door locks are disconnected from the coordinator can be known, namely which intelligent door locks are not on line.

In addition, when the router is disconnected from the coordinator, the intelligent door lock connected with the router is also disconnected from the coordinator. For example, when the second router is disconnected from the first coordinator, the second and third smart door locks are also disconnected from the coordinator. Table 2 within the first coordinator becomes:

TABLE 3

ID of first coordinator	ID of connected router	ID of connected intelligent door lock
			X1	L1	M1
		M2

Thus, the first coordinator can add and delete IDs of all devices within the network in which the first coordinator is located within the association table.

Further, the coordinator may not delete the stored ID of the router when the network connection with the router is disconnected, because the coordinator can simultaneously connect a plurality of routers, and even if the ID of the router is not deleted, the establishment of the connection between the coordinator and the router newly added to the network in which the coordinator is present is not affected. However, since the storage space of the coordinator is limited, in order to save the storage space of the coordinator, when the connection between the coordinator and the router is disconnected, the ID of the router is deleted.

Referring to fig. 8, fig. 8 shows a data processing method according to another embodiment of the present invention, which is applied to the system and the apparatus. The data processing method comprises the following steps: step S801, step S802, and step S803. The steps included in the method of the present embodiment will be described in detail in the interaction process between the coordinator and the router.

Step S801: monitoring the connection state with the gateway.

The method for monitoring the connection state with the gateway by the coordinator may be that the coordinator sends a heartbeat packet to the gateway at regular time, and determines whether a heartbeat packet ACK returned by the gateway based on the heartbeat packet sent by the coordinator is received within a third preset time period, and if the heartbeat packet ACK returned by the gateway based on the heartbeat packet sent by the coordinator is received within the third preset time period, the coordinator is determined to be normally connected with the gateway. And the starting point of the third preset time period is the time point when the coordinator sends the heartbeat packet to the gateway.

Step S802: when the connection with the gateway is disconnected, the coordinator disconnects the network connection of all devices connected with the coordinator.

The coordinator disconnects the network of all devices participating in the network where the coordinator is located, and the specific way may be that the coordinator turns off the power supply to disconnect the network of the coordinator from other devices. The method for the coordinator to disconnect the network connections of all the devices in the network where the coordinator is located may be to close a preset time period and then reestablish the connections with all the devices in the network, or may be to disconnect the network continuously. The preset time length is set according to the actual application scene.

When the network connection between the coordinator and other devices such as the router is disconnected, the router searches for other coordinators within a preset range and establishes network connection with other coordinators. Therefore, when the coordinator is disconnected from the gateway, that is, the ZigBee network where the coordinator is located cannot access the internet through the gateway, the coordinator disconnects all devices connected to the coordinator from the network of the coordinator, so that devices such as a router under the coordinator network can join another ZigBee network capable of communicating with the internet.

The monitoring unit 910 is configured to monitor a network connection status with the coordinator.

The searching unit 950 is configured to search for other coordinators within a preset range when the coordinator network connection status is disconnected.

The connection unit 960 is used to connect with one of the searched other coordinators.

It is clear to those skilled in the art that, for convenience and brevity of description, the specific working processes of the above-described systems, apparatuses and units may refer to the corresponding processes in the foregoing method embodiments, and are not described herein again.

Referring to fig. 10, fig. 10 is a block diagram illustrating a data processing apparatus 220 according to an embodiment of the present invention, where the data processing apparatus 220 is applied in a router, and the data processing apparatus 220 includes: the device comprises a monitoring unit 910, an obtaining unit 920, a receiving unit 930, a storage policy modifying unit 940, a searching unit 950, a connecting unit 960 and a storage unit 970.

The monitoring unit 910 is configured to monitor a network connection status with the coordinator. Specifically, the monitoring unit 910 includes a first determination subunit.

The first judging subunit is configured to judge that the network connection state with the coordinator is disconnection when the first data packet sent by the coordinator is not received within a first preset time period. Specifically, the method and the device are configured to determine that a network connection state with the coordinator is disconnection when a heartbeat packet sent by the coordinator at a preset sending interval is not received within a first preset time period, where an initial time of a first preset time is a time point of last receiving of the heartbeat packet sent by the coordinator, and the first preset time is greater than the sending interval.

In addition, the first determination subunit includes: a sending subunit and a second judging subunit.

The sending subunit is configured to send a second packet to the coordinator.

The second determining subunit is configured to determine that a network connection state with the coordinator is disconnection when a first data packet sent by the coordinator based on the second data packet is not received within a first preset time period, where a starting time point of the first preset time period is a time point of sending the second data packet.

The obtaining unit 920 is configured to obtain connection information of the coordinator, where the connection information is information stored when a connection is established with the coordinator.

The storage unit 970 is used for storing the acquired connection information in the memory.

The receiving unit 930 is configured to receive a modification instruction.

The storage policy modification unit 940 is configured to delete a preset storage policy according to the modification instruction, where the storage policy is used to store the connection information of the coordinator in a non-volatile memory.

The searching unit 950 is used to search for other coordinators within a preset range.

The storage unit 970 is also used to store connection information of the connected coordinator.

In summary, when the network connection between the device and the coordinator is disconnected, the device attempts to search for other coordinators within a preset range, and establishes a connection with one of the coordinators. Therefore, even if the network connection between the device and the coordinator is disconnected, resulting in the failure of the device to connect to the network, it is still possible to join a new network by connecting to one of the plurality of coordinators searched within the preset range, as compared to the related art. In the prior art, when the network connection between the equipment and the coordinator is disconnected, the equipment needs to search other coordinators and connect the coordinators by manually recovering the factory value of the equipment and other operations, so that the reliability of the network is effectively improved.
