Background technique
Due to lora physical layer wide coverage, communication stability is good, and LoRaWAN agreement framework is simple, meets big
Part Internet of Things application field, so LoRaWAN has covered multiple countries and regions as low-power consumption wan communication agreement.
When disposing LoRaWAN network, if encountering the region that can not dispose Ethernet, conventional LoRaWAN gateway will
Failure.Existing solution on the market passes through gateway mostly and 3G or 4G modular manner is added to extend LoRaWAN network, but this will increase
Add additional operators communication expense.And some basements or remote mountain areas are not completed with the region of carrier network covering
The program will be no longer applicable in.In addition, some companies pass through multi-hop ad hoc network agreement of the independent research based on lora physical layer, but this
It will be unable to be compatible with original LoRaWAN agreement, be not suitable for any wide-area deployment.
Summary of the invention
The purpose of the present invention is overcoming the shortcomings of LoRaWAN product scalability and compatibility, a kind of compatibility is provided
The relay system of LoRaWAN agreement.
In order to achieve the above object, the present invention is achieved by the following technical solutions:

It states and is communicated between several Tandem Gateways and center gateway, the center gateway is led to LoRaWAN protocol server
Letter.
Center gateway include the first LoRaWAN protocol module, LoRaWAN protocol-compliant module, the first trunk protocol module,
First LoRa RF hardware, the intercommunication of the first LoRaWAN protocol module and LoRaWAN protocol-compliant module, institute
State the intercommunication of LoRaWAN protocol-compliant module Yu the first trunk protocol module, the first trunk protocol module and the
The intercommunication of one LoRa RF hardware.
Tandem Gateway include the 2nd LoRa RF hardware, the second trunk protocol module, the 2nd LoRa RF hardware with
The intercommunication of second trunk protocol module.
The LoRaWAN node includes the 3rd LoRaWAN protocol module, the 3rd LoRa RF hardware, the third
The intercommunication of LoRaWAN protocol module and the 3rd LoRa RF hardware.
First LoRaWAN protocol module and the intercommunication of LoRaWAN protocol-compliant module are the first LoRaWAN agreement
Module sends trunk protocol group packet to LoRaWAN protocol-compliant module, and LoRaWAN protocol-compliant 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 agreement 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 protocol, LoRaWAN node can quickly network.
Detailed description of the invention
Fig. 1 is system block diagram of the invention；
Fig. 2 is communication flow diagram of the invention.
Specific embodiment
Technical solution 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 agreement, including LoRaWAN protocol server 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 server 1 is communicated.The center gateway 2 includes the first LoRaWAN protocol module 21, LoRaWAN agreement
Compatible modules 22, the first trunk protocol module 23, the first LoRa RF hardware 24, the first LoRaWAN protocol module 21 with
The intercommunication of LoRaWAN protocol-compliant module 22, the LoRaWAN protocol-compliant module 22 and the first trunk protocol module
23 intercommunication, the intercommunication of the first trunk protocol module 23 and the first LoRa RF hardware 24.In described
Include the 2nd LoRa RF hardware 31, the second trunk protocol module 32, the 2nd LoRa RF hardware 31 and second after gateway 3
The intercommunication of trunk protocol module 32.The LoRaWAN node 4 includes the 3rd LoRaWAN protocol module 42, the 3rd LoRa
RF hardware 41, the intercommunication of the 3rd the LoRaWAN protocol module 42 and the 3rd LoRa RF hardware 41.Described first
The intercommunication of LoRaWAN protocol module 21 and LoRaWAN protocol-compliant module 22 be the first LoRaWAN protocol module 21 to
LoRaWAN protocol-compliant module 22 sends trunk protocol group packet, and LoRaWAN protocol-compliant module 22 is to the first LoRaWAN agreement
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, physical layer uses lora radio frequency, and target is to realize
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
After packet all will pass through the first trunk protocol module, the trunk protocol of the second trunk protocol module is packaged 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 passes through the data packet and does periodic detection 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 module uses LoRaWAN gateway portion agreement completely, i.e., all to receiving
LoRaWAN data packet has been directly forwarded to LoRaWAN protocol server.First LoRaWAN gateway protocol module is only in central network
It shuts and comes into force, do not come into force on Tandem Gateway.
LoRaWAN protocol-compliant module, main first trunk protocol module of completing are led to the first LoRaWAN protocol module
Letter.Since trunk protocol and LoRaWAN consensus standard be not identical, so needing LoRaWAN protocol-compliant module to be adapted to, lead
Packet is unpacked and organized when completing to communicate between the first trunk protocol module and the first LoRaWAN protocol module.LoRaWAN agreement
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, communication flow diagram of the invention.As seen from the figure, center gateway possesses the first LoRaWAN agreement mould
Block, LoRaWAN protocol-compliant module, the function of three modules of the first trunk protocol module.Meanwhile center gateway passes through first
LoRa RF hardware and other Tandem Gateways, which are established, to be connected to the network, 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 node reports LoRaWAN data packet, Tandem Gateway passes through the second trunk protocol module for data
Packet is transmitted to center gateway.
The present invention extends LoRaWAN communication range on the basis of compatible LoRaWAN agreement, the present invention without
Carrier network improves the network coverage, reduces user's communications cost, is compatible with the LoRaWAN communication protocol of existing prevalence,
LoRaWAN node can quickly network.
It should be noted that listed above is only a kind of specific embodiment of the 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
Out or all deformations for associating, it is considered as protection scope of the present invention.
