Embodiment 1

[0040] Such as Figure 1-Figure 5 A LoRaWan data exchange method based on the enhanced MQTT message mechanism shown, including the following steps:

[0041] Step 1: Establish LoRaWAN terminals and LoRaWAN gateways at the perception layer, establish a data core layer at the network layer, and establish a data application management layer at the application layer;

[0042] The LoRaWAN terminal includes a LoRaWAN radio frequency module for connecting to the LoRaWAN network and transmitting data and a sensor module for collecting data;

[0043] The LoRaWAN terminal communicates with the LoRaWAN gateway through the LoRaWAN network;

[0044] The data core layer includes data distribution server, network server and MQTT message sending and receiving collection server cluster;

[0045] The data application management layer includes store-and-forward servers and application servers;

[0046] Step 2: The LoRaWAN terminal sends the data to the LoRaWAN gateway. After the LoRaWAN gatewa...

Abstract

The invention discloses a LoRaWan data exchange method based on an enhanced MQTT message mechanism, belonging to the technical field of Internet of things. A LoRaWAN terminal and a LoRaWAN gateway areestablished at a sensing layer; a data core layer is established at a network layer; a data application management layer is established at an application layer; and data interaction among each layeris realized through a MQTT middleware and a SSL certificate; therefore, the technical problem of implementing SSL transmission encryption through the MQTT protocol middleware during LoRaWAN data exchange is solved; and only service realization of a current Internet of things layer is required to be paid attention to when deploying debugging or evolving at the individual Internet of things layer; therefore, the works of development, deployment, debugging and evolving are greatly simplified, de-coupling is realized among Internet of things layers, which facilitates the independent evolution andreuse of each individual service layer. The data exchange system using the MQTT message mechanism disclosed by the invention is more robust and easy to expand; the invention realizes encrypted transmission of SSL; and compared with the systems in the prior art, the data transmission security of the entire system is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a LoRaWan data exchange method based on an enhanced MQTT message mechanism. Background technique [0002] LoRaWAN is based on LoRa communication to realize a set of communication protocols and system architecture for long-distance communication network design. [0003] LoRa is a spread spectrum modulation technology. LoRa's spread spectrum modulation greatly improves the sensitivity of the system and can transmit farther under the same transmission power. LoRaWAN is a protocol specification based on LoRa technology, developed and maintained by the LoRa Alliance. With the development of the Internet of Things industry, LoRaWAN is getting more and more attention from the industry. [0004] In order to solve the high concurrency problem when the number of LoRaWAN gateway devices connected to the server is huge, the existing LoRaWAN data exchange technology uses the ...
