Detailed Description
In order that the application may be readily understood, a more complete description of the application will be rendered by reference to the appended drawings. Exemplary embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The application has the following general ideas: the LoRaWAN protocol is a standard protocol, and the gateway can analyze the data packet uploaded by the terminal to obtain whether the protocol type followed by the terminal is the LoRaWAN protocol or not; if the protocol type is LoRaWAN protocol, the data packet is sent to the LoRaWAN server, otherwise, the data packet is sent to the self-research server. Therefore, the gateway can be compatible with LoRaWAN and self-research protocols, and the applicable scene of the gateway is enlarged.
In order to better understand the above technical solutions, the following detailed description will be made with reference to the accompanying drawings and specific embodiments, and it should be understood that specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, and not limit the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
Referring to fig. 1, the LoRa system of the present application includes a self-lapping terminal, a LoRa wan terminal, a gateway, a self-lapping server, and a LoRa wan server, where the gateway is used to implement communication between the self-lapping terminal, the LoRa wan terminal, the self-lapping server, and the LoRa wan server, and the gateway is a transfer station for data uplink and data downlink. The application carries out protocol distinguishing processing on the uplink part of the data on one hand and carries out priority processing on the downlink part of the data on the other hand.
Referring to fig. 2, the communication method compatible with the lorewan and the self-research protocol of the present application, the implementation main body is the gateway in fig. 1, and the method includes:
s201, the gateway acquires a data packet uploaded by a terminal;
s202, analyzing and obtaining the protocol type followed by the terminal according to the data packet;
the lorewan protocol is a well-known standard protocol, so the gateway can identify whether the terminal sending the data packet is the lorewan terminal according to the definition of the lorewan protocol, and if not, the gateway is necessarily a self-research terminal.
S203, if the protocol type is LoRaWAN protocol, the data packet is sent to the LoRaWAN server, otherwise, the data packet is sent to the self-research server.
In theory, when the terminal is identified as the self-polishing terminal in step S202, the data packet may be sent to all self-polishing servers, and the self-polishing server may determine whether to process the data packet by itself after receiving the data packet. For example, there are three self-polishing terminals A, B, C, corresponding to the three self-polishing servers A, B, C, assuming that the terminal a sends a data packet to the gateway, the gateway does not need to specifically analyze what self-polishing terminal the data packet belongs to, only needs to identify that the data packet is from the self-polishing terminal, then sends the data packet to the self-polishing server A, B, C at the same time, after the self-polishing server A, B, C receives the data packet, the server a identifies that the data packet conforms to the self-polishing protocol a, further processes the data packet, and other servers B, C identify that the data packet does not conform to the self-polishing protocol B, C, further does not process the data packet.
Preferably, the gateway can also identify the specific type of the self-research terminal sending the data packet, the data packet transmitted between the self-research terminal and the self-research server follows a specific verification mode, encryption mode or channel division mode (up-down same frequency, up-down different frequency, channel group planning and the like), and the gateway can distinguish private protocol data packets of different manufacturers and LoRaWAN protocol data packets according to the specific type. Accordingly, the method further comprises, correspondingly: if the protocol type followed by the terminal is analyzed to be the self-grinding protocol, the specific self-grinding protocol type followed by the terminal is analyzed further according to the specific verification mode, encryption mode or channel division mode followed by the data packet, and the data is forwarded to the specific self-grinding server. For example, continuing the above example, after the self-research terminal a sends the data packet based on the self-research protocol a, the gateway can identify the specific protocol type according to the verification mode, encryption mode or channel division mode of the self-research protocol a, so that only the data is forwarded to the server a.
As can be seen from the above, the gateway plays a role of data forwarding, and in other embodiments, the gateway may further participate in tasks such as channel allocation, and preferably, the method further includes: if the protocol type followed by the terminal is analyzed to be a self-research protocol and the data packet is a network access data packet, further analyzing data characteristic information carried by the network access data packet, wherein the characteristic information can be, for example, period or random, the length of the data packet, the real-time requirement of downlink and the like; and replying the channel and time used by the uplink data and the downlink data of the terminal to the terminal according to the data characteristic information, so that the terminal can transmit the data between the reply information of the gateway and the self-research server.
It should be noted that, the present application does not change the uplink behavior of the terminal of the LoRaWAN, otherwise, the universality of the LoRaWAN is affected. For the self-research protocol, the data of the LoRaWAN is interference, and only measures such as retransmission or interception of a channel before transmission can be taken for the interference. Of course, the allocation policy of the corresponding time, channel and other resources can be formulated for the data transmission of the self-research protocol. Also for the LoRaWAN protocol, the data of the self-lapping protocol is also an interference, since the mode of operation of the LoRaWAN theoretically involves the risk of data collisions.
Referring to fig. 3, the method of the present application further comprises:
s301, a gateway acquires a downlink data packet of a server;
s302, allocating medium priority to downlink data from the LoRaWAN server, and setting the downlink data from the research server as other priorities according to data requirements;
s303, queuing and transmitting the data packet to the corresponding terminal according to the priority.
If the downlink priority of the gateway is assumed to be 16 levels: 0-15,0 represents the highest priority, 15 represents the lowest priority, the priority of the LoRaWAN may be set to 8, and the data priority of the self-lapping protocol may be set to other levels according to actual needs, for example, the self-lapping protocol requirement is preferred over the LoRaWAN, the priority in 0-7 may be set, for example, the self-lapping protocol requirement is not higher than the LoRaWAN, the priority in 9-15 may be set.
That is, in the present application, for the communication between the terminal following the LoRaWAN protocol and the LoRaWAN server, the gateway is similar to a general LoRaWAN gateway, and only needs to queue with the self-research protocol downlink packet when going down, so as to follow a certain priority policy.
Therefore, in this embodiment, the gateway may be compatible with the lorewan protocol, and only may have a difference from a system without a self-polishing protocol in terms of downstream real-time performance, and in addition, the gateway may be simultaneously compatible with a self-polishing protocol system, and allocate different upstream resources and different downstream priorities according to the data characteristics of each terminal, so that the system better provides customized services for a specific scene.

and the data forwarding module is used for sending the data packet to the LoRaWAN server when the protocol type is analyzed to be the LoRaWAN protocol, or sending the data packet to the self-research server.
