The relay system of LoRaWAN agreements.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
A kind of relay system of compatible LoRaWAN agreements, including LoRaWAN protocol servers, center gateway, in several
It is communicated after between gateway, several LoRaWAN nodes, several described LoRaWAN nodes and several Tandem Gateways, institute
It states and is communicated between several Tandem Gateways and center gateway, the center gateway is led to LoRaWAN protocol servers
Letter.
Center gateway include the first LoRaWAN protocol modules, LoRaWAN protocol-compliants module, the first trunk protocol module,
First LoRa RF hardwares, the intercommunication of the first LoRaWAN protocol modules and LoRaWAN protocol-compliant modules, institute
State the intercommunication of LoRaWAN protocol-compliants module and the first trunk protocol module, the first trunk protocol module and the
The intercommunication of one LoRa RF hardwares.
Tandem Gateway include the 2nd LoRa RF hardwares, the second trunk protocol module, the 2nd LoRa RF hardwares with
The intercommunication of second trunk protocol module.
The LoRaWAN nodes include the 3rd LoRaWAN protocol modules, the 3rd LoRa RF hardwares, the third
The intercommunication of LoRaWAN protocol modules and the 3rd LoRa RF hardwares.
First LoRaWAN protocol modules and the intercommunication of LoRaWAN protocol-compliant modules are the first LoRaWAN agreements
Module sends trunk protocol group packet to LoRaWAN protocol-compliant modules, and LoRaWAN protocol-compliants module is assisted to the first LoRaWAN
View module sends trunk protocol and unpacks.
The center gateway be can access Ethernet gateway, the Tandem Gateway be can not access network based on ethernet network net
It closes.
Beneficial effects of the present invention are as follows：It is logical to extend LoRaWAN on the basis of compatible LoRaWAN agreements by the present invention
Believe that range, the present invention improve the network coverage without carrier network, reduce user's communications cost, compatibility is existing
Popular LoRaWAN communication protocols, LoRaWAN nodes can quickly network.
Description of the drawings
Fig. 1 is the system block diagram of the present invention；
Fig. 2 is the communication flow diagram of the present invention.
Specific implementation mode
Technical scheme of the present invention is described further with reference to the accompanying drawings of the specification：
As shown in Figure 1 and Figure 2, a kind of relay system of compatible LoRaWAN agreements, including LoRaWAN protocol servers 1, in
Heart gateway 2, several Tandem Gateways 3, several LoRaWAN nodes 4, several described LoRaWAN nodes 4 and several relayings
Communicated between gateway 3, communicated between several described Tandem Gateways 3 and center gateway 2, the center gateway 2 with
LoRaWAN protocol servers 1 are communicated.The center gateway 2 includes the first LoRaWAN protocol modules 21, LoRaWAN agreements
Compatible modules 22, the first trunk protocol module 23, the first LoRa RF hardwares 24, the first LoRaWAN protocol modules 21 with
The intercommunication of LoRaWAN protocol-compliants module 22, the LoRaWAN protocol-compliants module 22 and the first trunk protocol module
23 intercommunication, the intercommunication of the first trunk protocol module 23 and the first LoRa RF hardwares 24.In described
Include the 2nd LoRa RF hardwares 31, the second trunk protocol module 32, the 2nd LoRa RF hardwares 31 and second after gateway 3
The intercommunication of trunk protocol module 32.The LoRaWAN nodes 4 include the 3rd LoRaWAN protocol modules 42, the 3rd LoRa
RF hardware 41, the intercommunication of the 3rd the LoRaWAN protocol modules 42 and the 3rd LoRa RF hardwares 41.Described first
The intercommunication of LoRaWAN protocol modules 21 and LoRaWAN protocol-compliants module 22 be the first LoRaWAN protocol modules 21 to
LoRaWAN protocol-compliants module 22 sends trunk protocol group packet, and LoRaWAN protocol-compliants module 22 is to the first LoRaWAN agreements
Module 21 sends trunk protocol and unpacks.The center gateway 2 is the gateway that can access Ethernet, and the Tandem Gateway 3 is not
It can access the gateway of Ethernet.
First trunk protocol module, the second trunk protocol module all mainly realize the multi-hop ad hoc between multiple gateways
Network.For the trunk protocol module between data link layer and physics interlayer, it is to realize that physical layer, which uses lora radio frequencies, target,
In the seamless original communication protocol stack of insertion, the application of upper layer software (applications) is preferably supported.Therefore, all upper layer communication protocol datas
Packet will be all packaged by the trunk protocol of the first trunk protocol module, the second trunk protocol module after again in trunk protocol network
Communication.In order to find that surrounding neighbours equipment whether there is, trunk protocol periodically understands overseas broadcast neighbor monitoring and detecting data packet.Not only such as
This, agreement also does periodic detection by the data packet to link packet drop rate and transmission delay, to realize that link-quality is assessed.It
Afterwards, the neighbor device for selecting link-quality optimal is forwarded target device by agreement.Therefore, when extraneous ring
When border or device location change, the first trunk protocol module, the second trunk protocol module can be assessed according to new link-quality
As a result new network topology is formed, extraneous variation is then adapted to.
The first LoRaWAN protocol modules use LoRaWAN gateway portion agreements completely, i.e., all to receiving
LoRaWAN data packets have been directly forwarded to LoRaWAN protocol servers.First LoRaWAN gateway protocols module is only in central network
It shuts and comes into force, do not come into force on Tandem Gateway.
LoRaWAN protocol-compliant modules, main first trunk protocol module of completing are led to the first LoRaWAN protocol modules
Letter.Since trunk protocol and LoRaWAN consensus standards differ, so needing LoRaWAN protocol-compliants module to be adapted to, lead
Packet is unpacked and organizes when completing to communicate between the first trunk protocol module and the first LoRaWAN protocol modules.LoRaWAN agreements
Compatible modules, which are only shut in central network, to come into force, and does not come into force on Tandem Gateway.
As shown in Fig. 2, the communication flow diagram of the present invention.As seen from the figure, center gateway possesses the first LoRaWAN agreement moulds
The function of block, LoRaWAN protocol-compliants module, three modules of the first trunk protocol module.Meanwhile center gateway passes through first
LoRa RF hardwares establish network connection with other Tandem Gateways, and relay forwarding packet is forwarded by the network.
Simultaneously as Tandem Gateway only serves data packet forwarding capability, so Tandem Gateway only has the second trunk protocol
Module software.When LoRaWAN nodes report LoRaWAN data packets, Tandem Gateway is by the second trunk protocol module by data
Packet is transmitted to center gateway.
The present invention extends LoRaWAN communication ranges on the basis of compatible LoRaWAN agreements, the present invention without
Carrier network improves the network coverage, reduces user's communications cost, is compatible with the LoRaWAN communication protocols of existing prevalence,
LoRaWAN nodes can quickly network.
It should be noted that listed above is only a kind of specific embodiment of the present invention.It is clear that the invention is not restricted to
Upper embodiment, can also be there are many deforming, in short, those skilled in the art can directly lead from present disclosure
All deformations for going out or associating, are considered as protection scope of the present invention.
