Based on the above hardware structure, embodiments of the present invention are proposed.
Referring to fig. 2, fig. 2 is a schematic flow chart of a network topology detection method according to a first embodiment of the present invention, where the network topology detection method includes the following steps:
step S202: a selected ZigBee device in the ZigBee network sends an inquiry address request to a target ZigBee device with a known address in the ZigBee network.
It can be understood that the specification in the ZigBee protocol defines three types of devices (also referred to as nodes), each having its own functional requirements; wherein:
coordinator node coordinator: the ZigBee network is responsible for establishing a network, can be configured for receiving and transmitting, is a gathering point of information of each node of the ZigBee network, is a core device of the network, is responsible for constructing, maintaining and managing the network, and realizes data transmission of each node and an upper computer in a serial mode.
Router node Router: the star network does not use a router, and performs path search and path maintenance of data, so that a node can join the network and assist the communication of child nodes to be a relay between a terminal node and a coordinator node, and the communication between the terminal node and the coordinator node is relayed.
Terminal node end device: the terminal node is responsible for receiving and transmitting signals, cannot transmit the signals and is low in power consumption, and the terminal node can be directly connected to the coordinator node or can be connected to the coordinator node through the router node.
The selected device in the embodiment refers to any ZigBee device running in the ZigBee network, and is also called as a detection device, namely the selected device completes network topology detection without additional software and hardware devices; the selected device may be a coordinator, a router, or a terminal, and in practical applications, the selected device may be flexibly adjusted according to a specific application scenario.
In some examples, the coordinator node is heavily loaded; thus, the router node may be selected as the selected device.
In some examples, since a star network does not use routers; accordingly, either the coordinator node or the terminal node may be selected as the selected device.
The target ZigBee device in this embodiment refers to a ZigBee device having a known address in a ZigBee network; the target ZigBee device can be a coordinator, a router or a terminal, and in practical application, the target ZigBee device can be flexibly adjusted according to a specific application scene.
The secondary ZigBee device in the embodiment refers to a ZigBee device mounted at the next stage/layer of the target ZigBee device; the secondary ZigBee device can be a coordinator, a router or a terminal, and in practical application, the secondary ZigBee device actually mounted under the target ZigBee device is used as a standard.
The query address request in this embodiment is what the target address of the secondary ZigBee device for querying the target ZigBee device is, and accordingly, the response information is what the target address of the secondary ZigBee device for replying to the target ZigBee device is specifically. For example, the selected device sends a query address request to the target ZigBee device 1, wherein the secondary ZigBee devices of the target ZigBee device are the ZigBee device 11, the ZigBee device 12, and the secondary ZigBee device 13, respectively, then the query address request is a destination address of the query ZigBee device 11, the ZigBee device 12, and the secondary ZigBee device 13, and the response information includes the destination addresses of the ZigBee device 11, the ZigBee device 12, and the secondary ZigBee device 13.
It can be understood that in the present embodiment, the detection may be performed from a target ZigBee device having a known address in the ZigBee network; therefore, the selected ZigBee device can send an inquiry address request to a target ZigBee device with a known address in the ZigBee network, so that the target address of a secondary ZigBee device of the target ZigBee device is obtained, and the topological relation of the ZigBee network is detected.
In some examples, the known address may be a network address, and then the subsequently acquired target address of the secondary ZigBee device of the target ZigBee device is also the network address. The network address refers to a 16-bit network address, which is allocated after the device joins the ZigBee network and is unique in the ZigBee network, so as to be used for identifying the device and transmitting data in the ZigBee network.
In some examples, the known address may be a physical address, and then the subsequently acquired target address of the secondary ZigBee device of the target ZigBee device is also a physical address. Where physical address refers to a 64-bit IEEE address, a globally unique address, which will follow the life of the device once assigned, is usually set by the manufacturer or at the time of installation, and is maintained and assigned by the IEEE organization.
Step S204: selecting ZigBee equipment to receive response information sent by target ZigBee equipment so as to detect the topological relation of the ZigBee network; wherein the reply information includes a target address of a secondary ZigBee device of the target ZigBee device.
It can be understood that after a selected ZigBee device in the ZigBee network sends an inquiry address request to a target ZigBee device having a known address in the ZigBee network, the target ZigBee device will receive the inquiry address request sent by the selected ZigBee device accordingly; further, the target ZigBee device generates corresponding response information according to the inquiry address request and sends the response information to the selected ZigBee device, and accordingly, the selected ZigBee device receives the response information sent by the target ZigBee device.
It can be understood that several APIs for querying 16-bit network address and 64-bit IEEE address are reserved in the system implemented by the ZigBee protocol:
obtaining the network address of the father node: the agent 16 NLME _ GetCoordShortAddr (void);
obtaining the physical address of the father node: void NLME _ GetCoordExtAddr (byte);
obtaining the network address of the user: the uint16 NLME _ GetShortAddr (void);
get its own physical address: byte NLME _ GetExtAddr (void);
querying the remote device network address according to the known physical address:
afStatus_t ZDP_NwkAddrReq(uint8*IEEEAddress,byte ReqType,byte StartIndex,byte SecurityEnable)；
querying the remote device physical address from the known network address:
afStatus_tZDP_IEEEAddrReq(uint16 shortAddr,byte ReqType,byte StartIndex,byte SecurityEnable)；
parsing the prototype of the address function:
ZDO_NwkIEEEAddrResp_t*ZDO_ParseAddrRsp(zdoIncomingMsg_t*inMsg)
that is, the reply information in the present embodiment may include other addresses in addition to the target addresses of the secondary ZigBee devices of the target ZigBee devices, and the included other addresses may be of a different type from the known addresses.
In some examples, the reply information comprises a target address of a secondary ZigBee device of the target ZigBee device, and a physical address of the target ZigBee device; wherein the target addresses of the secondary ZigBee devices of the target ZigBee device may be presented in a list form.
In some examples, the reply information includes a target address of a secondary ZigBee device of the target ZigBee device, and a network address of the target ZigBee device.
In some examples, the reply information includes a target address of a secondary ZigBee device of the target ZigBee device, a network address of the target ZigBee device, and a network address of the target ZigBee device.
For example, the following steps are carried out:
if the target ZigBee device with the known network address of 0x0000 is used, the physical address of the target ZigBee device may be obtained by using the API (i.e., ieee addrreq () function) that queries the physical address of the remote device according to the known network address; when a target ZigBee device with a network address of 0x0000 receives an inquiry address request sent by a selected ZigBee device, a corresponding response message is returned, the response message enters a ZDO layer of the selected ZigBee device, an API (namely a ParseAddrRsp () function) for analyzing an address function is called in the ZDO layer to analyze the response message, and the response message contains the network address of the target ZigBee device with the network address of 0x0000 and the physical address of the target ZigBee device with the network address of 0x0000 besides the network address of the ZigBee device at the next stage/layer of the target ZigBee device with the network address of 0x 0000. It can be understood that, in practical applications, the target ZigBee device with the network address 0x0000 is the coordinator.
It should be noted that, in practical applications, the specific address included in the response message may be flexibly adjusted according to a specific application scenario.
In this embodiment, a ZigBee device is selected from the ZigBee network as a detection device (i.e., a selected device), and the selected device performs packet capturing to obtain a target address of a secondary ZigBee device of a target ZigBee device, so as to detect a topological relation of the ZigBee network. Therefore, extra software and hardware support is not needed, and therefore the network topology detection cost is reduced; in addition, the target address of the secondary ZigBee device of the target ZigBee device can be obtained at any time in a mode that the selected device actively initiates inquiry, and the obtaining time depends on the selected device, so that the phenomenon of low passive obtaining efficiency through additional software and hardware devices in the prior art is avoided, and the network topology detection efficiency is improved; meanwhile, the detection device is a ZigBee device operating in the ZigBee network, so that the detection device knows the channels of the detection device and the surrounding devices, and does not need to scan all the devices, thereby further improving the network topology detection efficiency.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a network topology detection method according to a second embodiment of the present invention; in this embodiment, after the ZigBee device is selected to receive the response information sent by the target ZigBee device in step S204, the network topology detecting method may further include the following steps:
step S206: and replacing the target ZigBee device with a secondary ZigBee device, returning to step S202, sending an inquiry address request to the target ZigBee device with a known address in the ZigBee network by the selected ZigBee device in the ZigBee network, and circulating until the selected ZigBee device receives the target addresses of all other ZigBee devices except the selected ZigBee device in the ZigBee network.
It can be understood that, in the first embodiment, the details of the selecting ZigBee device sending the query address request to the target ZigBee device with a known address in the ZigBee network and obtaining the target address of the secondary ZigBee device of the target ZigBee device are described above; but the corresponding process is the target address acquisition process of the primary ZigBee device. In the embodiment, the target addresses of all the other ZigBee devices in the ZigBee network except the selected ZigBee device are obtained through hierarchical circulation.
By way of example:
setting a target ZigBee device 1 with a known address in the ZigBee network; wherein, the secondary ZigBee devices mounted under the target ZigBee device 1 are a secondary ZigBee device 11, a secondary ZigBee device 12, and a secondary ZigBee device 13, respectively; through steps S202 to S204 in the first embodiment, the selected ZigBee device can acquire the target addresses of the secondary ZigBee device 11, the secondary ZigBee device 12, and the secondary ZigBee device 13;
further, a secondary ZigBee device 11, a secondary ZigBee device 12, and a secondary ZigBee device 13 are respectively used as target ZigBee devices; the secondary ZigBee devices mounted under the target ZigBee device 11 are a secondary ZigBee device 111 and a secondary ZigBee device 112, respectively, the secondary ZigBee device mounted under the target ZigBee device 12 is a secondary ZigBee device 121, and the secondary ZigBee devices mounted under the target ZigBee device 13 are a secondary ZigBee device 131, a secondary ZigBee device 132, and a secondary ZigBee device 133, respectively; through steps S202-S204 in the first embodiment, the selected ZigBee device can acquire the target addresses of the secondary ZigBee device 111, the secondary ZigBee device 112, the secondary ZigBee device 121, the secondary ZigBee device 131, the secondary ZigBee device 132, and the secondary ZigBee device 133;
and circulating in sequence until the selected ZigBee device receives the target addresses of all other ZigBee devices except the selected ZigBee device in the ZigBee network.
In this embodiment, the target addresses of all the other ZigBee devices in the ZigBee network except the selected ZigBee device can be obtained through hierarchical circulation, so that the topology type of the ZigBee network can be determined subsequently according to the obtained target addresses of all the other ZigBee devices in the ZigBee network except the selected ZigBee device.
Referring to fig. 4, fig. 4 is a schematic flow chart of a network topology detection method according to a third embodiment of the present invention; in this embodiment, after looping back to the step that the selected ZigBee device receives the target addresses of all other ZigBee devices in the ZigBee network except the selected ZigBee device in step S206, the network topology detection method may further include the steps of:
step S208: determining the topology type of the ZigBee network according to the target addresses of all ZigBee devices; wherein the topology type comprises a star network topology, a tree network topology, or a mesh network topology.
It can be understood that specifications in the ZigBee protocol define three types of network topology types; wherein:
star network topology: the system comprises a coordinator node and a series of terminal nodes; it is the simplest of three topologies; each EndDevice can only communicate with the coordinator Co-coordinator node.
Tree network topology: the system comprises a coordinator node, a router node and a terminal node; the Co-coordinator may connect a series of routers and end devices, and the routers of its children nodes may also connect a series of routers and end devices, this feature allowing it to replicate multiple levels.
Mesh network topology: including the Co-coordinator, router and EndDevice series; this topology can constitute a very complex network and has self-organizing, self-healing functionality, which is the same as a tree network topology, but a mesh network topology has more flexible information routing rules and can communicate directly between routing nodes if possible, and furthermore the network can communicate through multiple hops.
In this embodiment, after the step of selecting the target addresses of all the ZigBee devices in the ZigBee network except the selected ZigBee device is performed, the specific topology type of the detected ZigBee network may be determined according to the target addresses of all the ZigBee devices.
In the embodiment, the target addresses of all the other ZigBee devices except the selected ZigBee device in the ZigBee network are obtained through hierarchy circulation, and the topology type of the ZigBee network is determined according to the obtained target addresses of all the other ZigBee devices except the selected ZigBee device in the ZigBee network, so that the detection efficiency is high, and the cost is low.
