For example, in some embodiments, multiple devices may be used to implement the functions performed by server 102. Alternatively, the functionality of server 102 may be implemented using cloud services.
Gateway system
Based on the above exemplary system, the present embodiments provide a gateway system that is applied to the communication network 104 in the above exemplary system. As shown in fig. 2, the gateway system 200 includes a plurality of gateways 201, each gateway 201 being connected to each other to form a mesh network, each gateway 201 being connected to at least one node 106, each gateway 201 storing node information of each node 106 connected to the gateway 201. The node information of each node 106 is stored in at least two gateways 201.
Each gateway 201 is connected to one or more nodes 106, and the gateway 201 may receive communication data transmitted from the connected nodes 106 and transmit the communication data to a server through a network other than the gateway system 200, such as a local area network, the internet, or the like, or may transmit the communication data to other gateways 201, and transmit the communication data to the server through a network other than the gateway system 200 by other gateways 201. The gateway 201 may also receive communication data sent by a server through a network other than the gateway system 200, such as a local area network, the internet, etc., and send the communication data to the connected node 106, or send the communication data to other connected gateways 201, and the other gateways 201 send the communication data to the connected node 106. Two-way communication of the node 106 with the server may be achieved through at least one gateway 201 in the gateway system 200.
Each gateway 201 is connected to one or more nodes 106, and the gateway 201 may receive communication data of one node 106 connected and send the communication data to another node 106 connected, or send the communication data to other gateways 201, and send the communication data to the connected nodes 106 by other gateways 201, and through at least one gateway 201 in the gateway system 200, bidirectional communication between the nodes 201 may be achieved.
When forwarding communication data of the node 106, the gateway 201 needs node information of the node 106, where the node information includes identification information, capability information, status information, configuration information, security information, and the like of the node, so as to ensure reliability and security of communication between the node 106 and a server. When one node 106 is connected to the gateway 201, the gateway 201 acquires and stores node information of the node 106, and the gateway 201 performs protocol conversion and data forwarding on communication data of the node 106 based on the stored node information. When the gateway 201 fails, the new gateway replaces the failed gateway, and needs to acquire the backup node information, so that the new gateway can perform protocol conversion and data forwarding on the communication data of the corresponding node 106 based on the acquired node information, without the need of re-networking the node 106.
In the embodiment of the present application, among the plurality of gateways 201 that constitute the mesh network, each of the gateways 201 stores node information of each node 106 to which it is connected, and the node information of each node 106 is stored in at least two of the gateways 201, that is, the node information of each node 106 is stored not only in the gateway 201 to which it is connected but also in at least one gateway 201 that is not directly connected to the rest. When one gateway 201 fails, node information of nodes 106 connected to the failed gateway 201 is stored in at least one other gateway 201, and after the failed gateway 201 is replaced by a new gateway, the new gateway may obtain node information of each node 106 connected to the failed gateway 201 from the other gateway 201, so that nodes 106 that have previously communicated through the failed gateway 201 may communicate through the new gateway. Because the node information of each node 106 only needs to be stored on at least two gateways 201, and each gateway 201 is not required to store the node information of all nodes 106, the backup requirement of the node information can be met, and the requirement on the storage space of the gateway 201 is reduced, so that the cost of the gateway 201 can be reduced, and the cost of the gateway system 200 can be further reduced.
In one possible implementation, for each first gateway of the gateways 201 included in the gateway system 200, node information of the nodes 106 connected to the first gateway is stored in at least one second gateway included in the gateway 200, the first gateway and the second gateway being different gateways.
The first gateway may be any gateway 201 in the gateway system 200, corresponding to the first gateway, and the second gateway may be any gateway 201 in the gateway system 200 different from the first gateway. The same gateway 201 may act as a second gateway to a different first gateway. The first gateway and the second gateway are illustrated below.
Fig. 3 is a schematic diagram of a gateway system of one embodiment of the present application. As shown in fig. 3, gateway system 200 includes gateway a 0 To gateway A n N+1 gateways in total, gateway A 0 With node B 1 To node B 50 A total of 50 nodes are connected with gateway A 1 With node B 51 To node B 100 A total of 50 nodes are connected. Gateway A 0 On which node B is stored 1 To node B 50 Node information of each node in the network, gateway A 1 And gateway A 2 Node B is also stored in 1 To node B 50 Node information of each node in the plurality of nodes. Gateway A 1 Node B is stored therein 51 Node B 100 Node information of each node in the pool, gateway A 2 Node B is also stored in 51 To node B 100 Node information of each node in the plurality of nodes.
Gateway A 0 When being used as a first gateway, gateway A 1 And gateway A 2 For gateway A 0 And a corresponding second gateway. Gateway A 1 When being used as a first gateway, gateway A 2 For gateway A 1 And a corresponding second gateway. Gateway A 2 As gateway A 0 And gateway A 1 Not only store gateway a 2 Node information of each connected node is also stored with a gateway A 0 And gateway A 1 And node information of each connected progress.
In this embodiment of the present application, for any first gateway in the gateway system 200, node information of each node 106 connected to the first gateway is stored in one or more second gateways in a unified backup manner, that is, node information of each node 106 connected to the first gateway is stored in the second gateway, and when the first gateway fails, node information of each node 106 connected to the first gateway can be obtained from one of the second gateways, and the obtained node information is imported into a new gateway that replaces the first gateway, so that the new gateway can replace the first gateway to implement communication of the node 106. Because the node information of each node connected with the first gateway is stored on each second gateway, the node information is only required to be acquired from one of the second gateways when the first gateway is replaced, so that the node information is more convenient and rapid to acquire, and the convenience of managing the nodes can be improved.
Fig. 4 is a schematic diagram of a gateway system of one embodiment of the present application. As shown in fig. 4, each gateway 201 stores not only node information of each node connected to the current gateway (first gateway) and node information of each node connected to the backup gateway (corresponding first gateway when serving as the second gateway), but also a cross storage information table. The corresponding relation between the first gateway and the second gateway is recorded in the cross storage information table.
For the corresponding first gateway and second gateway, the second gateway stores node information of each node 106 connected to the first gateway. For example, as shown in FIG. 3, gateway A 1 In which gateway A is stored 0 The node information of each connected node is recorded with gateway A in the cross storage information table 0 As a first gateway and gateway A 1 As a correspondence of the second gateway. Gateway A 2 In which gateway A is stored 0 The node information of each connected node is recorded with gateway A in the cross storage information table 0 As a first gateway and gateway A 2 As a correspondence of the second gateway. Gateway A 2 In which gateway A is stored 1 The node information of each connected node is recorded with gateway A in the cross storage information table 1 As a first gateway and gateway A 2 As a correspondence of the second gateway.
Table 1 below is an example of a cross storage information table, in which gateway IDs corresponding to a first gateway and a second gateway are recorded, where gateway 0 to gateway n are gateway IDs of n gateways included in the gateway system, respectively, gateway 0 corresponds to gateway x and gateway y, and node information of nodes connected by two gateways, whose gateway IDs are gateway x and gateway y, is stored in the gateway whose gateway ID is gateway 0. It should be appreciated that in table 1 below, x, y, k, m and z are both positive integers less than n, n being a positive integer.
TABLE 1
The cross storage information table records which gateway the node information of the node connected with each gateway is backed up and stored in, the same cross storage information table is stored in each gateway, the cross storage information table is commonly maintained by each gateway, and the backup position of the node information of the node connected with any gateway in the gateway system can be determined according to the cross storage information table.
In this embodiment of the present application, a cross storage information table is stored in each gateway, where a correspondence between a first gateway and a second gateway is recorded in the cross storage information table, and a backup position of node information of a node connected to each gateway may be determined according to the cross storage information table, so after a certain gateway fails, it may be determined according to the cross storage information table, which gateway or gateways the node information of the node connected to the failed gateway is stored in, further node information of the node connected to the failed gateway is obtained from the corresponding gateway, and the obtained node information is imported into a new gateway that replaces the failed gateway, so that each node connected to the failed gateway may communicate through the new gateway. By storing the cross storage information table in the gateway, the backup position of the node information can be rapidly determined, so that the node information can be rapidly imported into a new gateway when the gateway is replaced, and the efficiency of replacing the gateway is improved.
In one possible implementation, after the node information of each node connected to the first gateway is changed, the first gateway may synchronize the changed node information to each corresponding second gateway.
The second gateway stores node information of each node connected with the first gateway, if the node information of each node connected with the first gateway is changed, the first gateway updates the stored node information of each node connected with the first gateway, and the first gateway synchronizes the changed node information into each second gateway so that the node information backed up by the second gateway is identical to the node information of each node connected with the first gateway stored by the first gateway. The change of the node information includes a content change of the node information of a certain node or a plurality of nodes, a deletion of the node information of a certain node or a plurality of nodes, a new addition of the node information of a certain node or a plurality of nodes, and the like.
In the embodiment of the application, after the node information of each node connected with the first gateway is changed, the first gateway realizes the communication of each connected node based on the changed node information, and if the gateway performs protocol conversion and data forwarding on the communication data of the nodes based on the node information before the change, at least part of the nodes cannot normally communicate. After the first gateway synchronizes the changed node information to the second gateway, if the first gateway fails, the changed node information can be acquired from the second gateway and imported into the new gateway, so that the new gateway performs protocol conversion and data forwarding on the communication data of the nodes based on the changed node information, each node connected with the new gateway is guaranteed to be capable of normally communicating, and therefore reliability of node communication after the gateway is replaced can be improved.
In one possible implementation manner, the Mesh network formed by the connection of the gateways may be a bluetooth low energy Mesh network or a ZigBee Mesh network, that is, the gateway system 200 is suitable for a bluetooth Mesh network constructed based on bluetooth low energy (Bluetooth Low Energy, BLE), and is also suitable for a Mesh network constructed based on ZigBee, so as to ensure the applicability of the gateway system 200.

As shown in fig. 5, the node management method includes the steps of:
step 501, the first gateway stores node information of each node connected to the first gateway.
After a node is connected to a first gateway, that is, the node is connected to the network through the first gateway, node information of the node is stored in the first gateway, so that the first gateway stores node information of each node connected to the first gateway.

And for each node connected with the first gateway, sending the node information of the node to at least one second gateway outside the first gateway, and backing up the node information of the node on the second gateway. For each node connected to the gateway system, the node information of the node is stored not only in the first gateway connected with the node but also in the second gateway not directly connected with the node, so that the backup of the node information is realized.

Because the node information of each node is only stored on at least one second gateway for backup, and each gateway is not required to store the node information of all nodes, the backup requirement of the node information can be met, and the requirement on the storage space of the gateway is reduced, so that the cost of the gateway can be reduced, and the cost of a gateway system can be further reduced.
In one possible implementation manner, when the node information of each node connected to the first gateway is sent to the second gateway, the node information of each node connected to the first gateway may be sent to at least one second gateway, so that each second gateway stores the node information of each node connected to the first gateway.

Because the node information of each node connected with the first gateway is stored on each second gateway, the node information is only required to be acquired from one of the second gateways when the first gateway is replaced, so that the node information is more convenient and rapid to acquire, and the convenience of managing the nodes can be improved.
In one possible implementation manner, when node information of each node connected to the first gateway is sent to the second gateway, at least one second gateway corresponding to the first gateway may be determined according to a cross storage information table stored in the first gateway, and then the node information of each node connected to the first gateway is sent to each second gateway corresponding to the first gateway, so that node information of each node connected to the first gateway is stored in each second gateway. Each gateway included in the gateway system stores a cross storage information table, and the cross storage information table records the corresponding relation between the first gateway and the second gateway.
In the embodiment of the application, each gateway stores a cross storage information table, the corresponding relation between the first gateway and the second gateway is recorded in the cross storage information table, the second gateway corresponding to the first gateway is determined according to the cross storage information table, then node information of each node connected with the first gateway is stored on the second gateway, if the first gateway breaks down, the second gateway storing the node information of the node connected with the first gateway can be determined according to the cross storage information table, then the node information of the node connected with the first gateway can be obtained from the second gateway, the obtained node information is imported into a new gateway for replacing the first gateway, and all the nodes connected with the first gateway can communicate through the new gateway before the first gateway, so that the node information can be quickly imported into the new gateway when the gateway is replaced, and the efficiency of replacing the gateway is improved.
In one possible implementation, in response to a change in node information transmission of each node to which the first gateway is connected, the changed node information is synchronized to a second gateway corresponding to the first gateway.
In the embodiment of the application, after the node information of each node connected with the first gateway is changed, the first gateway realizes the communication of each connected node based on the changed node information, and if the gateway performs protocol conversion and data forwarding on the communication data of the nodes based on the node information before the change, at least part of the nodes cannot normally communicate. After the changed node information is synchronized to the second gateway, if the first gateway fails, the changed node information can be acquired from the second gateway and imported into the new gateway, so that the new gateway performs protocol conversion and data forwarding on the communication data of the nodes based on the changed node information, each node connected with the new gateway can be guaranteed to normally communicate, and the reliability of node communication after the gateway is replaced can be improved.
In one possible implementation, when a node is connected to a first gateway, that is, when a new node enters the network through the first gateway, a communication address may be allocated to the node according to an allocable address range corresponding to the first gateway, so that each node connected to the gateway system has a different communication address.
The nodes communicate through the gateway, namely, the gateway forwards data according to the communication address of the nodes, and in order to ensure that the nodes can normally communicate, each node connected to the gateway system needs to have different communication addresses. And the gateway distributes communication addresses for nodes connected with the gateway in the allocable address ranges, so that different nodes are ensured to have different communication addresses.
Alternatively, the allocatable address range of the gateway may be determined from the gateway ID. For example, the upper limit of the number of connectable nodes of each gateway is N, N is a positive integer, and the gateway IDs of the gateways are numbered in integer order from 0, and the allocable address range corresponding to the gateway with the gateway ID M is [ mxn, (m+1) ×n ]. And determining an allocable address range for the gateway according to the gateway ID, and ensuring that the allocable address ranges of different gateways are not overlapped, so as to ensure that different nodes have different communication addresses.
In the embodiment of the application, different gateways correspond to non-overlapping allocable address ranges, and according to the allocable address range of each gateway, communication addresses are allocated to nodes connected to the gateway, so that different nodes are guaranteed to have different communication addresses, and further reliability of node communication is guaranteed.
