Embodiment Construction

[0055] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0056] Such as figure 1 As shown, the LoRa-based IoT system includes: LoRa network nodes, antenna transceiver system, LoRa gateway, MQTT server, HTTP application server, database, client (PAD, PC, PHONE);

[0057] The LoRa network nodes are deployed in practical application scenarios such as forests, farms, and fishing grounds. The nodes themselves have data processing capabilities, and can also wirelessly transmit data with the antenna transceiver system;

[0058] The antenna transceiver system is used for one-to-many wireless communication with LoRa network nodes, so as to realize the aggregation and distribution of different node data;

[0059] The LoRa gateway is located at the periphery of the antenna transceiver system, and performs data transmission through the wired form and the antenna transceiver system. The LoRa gateway has an Internet co...

Abstract

A method for node data reporting and instruction issuing based on LoRa Internet of Things comprises the following steps: step S1-1) the LoRa network node reports the data packet to the LoRa gateway according to the self-defined data format; Step S1-2) the LoRa gateway analyzes the data packet according to the self-defined data format, carries out integrity and correctness verification of each field and packet loss detection, and after the checksum detection is passed, a 64-bit LoRa gateway identification code is added into the data packet and sent to the MQTT server through the MQTT protocol;Step S1-3) the MQTT serv parses the data packet according to the self-defined data format, after passing the check and packet loss detection, encrypts all data units of the data packets, and then sends the data packets to the HTTP server through the MQTT protocol; Step S1-4) the HTTP server parses the data packet according to the self-defined data format, after the checksum packet loss detection is passed, decrypts all data units of the data packet, obtains the original data units, and then stores the data of each field of the data packet into the database.

Description

technical field [0001] The invention relates to the field of data transmission of the Internet of Things based on LoRa, in particular to a method for reporting data and issuing instructions based on the Internet of Things LoRa. Background technique [0002] As a wide-area Internet of Things technology, LoRa has the advantages of long-distance, low power consumption, and low operation and maintenance costs. It has been widely used at present. It is mainly used in short- and medium-distance communication of Internet of Things nodes, such as real-time monitoring systems for forest environments. The communication between the sensor node and the base tower in the middle, the communication between the irrigation controller and the base station in the automatic fertilization and irrigation system of the farm, etc. [0003] A complete LoRa-based IoT system includes basic components such as LoRa network nodes, antenna transceiver systems, LoRa gateways, MQTT servers, HTTP application...
