Internet of Things (IoT) communication method and device based on LoRa technology and storage medium

Abstract

The invention discloses an Internet of Things (IoT) communication method and device based on LoRa technology and a storage medium and belongs to the technical field of IoT communication. The method comprises the steps of obtaining the data information sent by an LoRa terminal in a preset transmission rate; determining the maximum transmission rate corresponding to the target signal to noise ratioand the target signal intensity; sending the maximum transmission rate as a first predicted transmission rate to the LoRa terminal; and receiving the data information sent by the LoRa terminal based on the first predicted transmission rate to realize the communication with the LoRa terminal. According to the method, the target signal to noise ratio and the target signal intensity sent by the LoRaterminal are obtained, and the maximum transmission rate corresponding to the target signal to noise ratio and the target signal intensity is taken as the first predicted transmission rate to be sentto the LoRa terminal, so that communication can be carried out on the basis of the first predicted transmission rate, shortening the communication duration and reducing the power consumption of the communication network between an LoRa server and the LoRa terminal.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication, in particular to an Internet of Things communication method, device and storage medium based on LoRa technology. Background technique [0002] In the Internet of Things communication technology, the longer the communication distance, the greater the power consumption of the communication. Therefore, a LPWAN (Low Power Wide Area Network, Low Power Wide Area Network) is proposed to realize the equal distance between smart agriculture and smart cities. LoRa technology is a typical low-power, long-distance wireless communication technology in LPWAN. [0003] In related technologies, since the life of the communication network between the LoRa terminal and the LoRa server mainly depends on the life of the LoRa terminal during the communication process of the Internet of Things, in order to prolong the life of the communication network, the LoRa with the smallest duty c...

Problems solved by technology

[0004] However, as the duty cycle of the LoRa terminal becomes smaller, the communication frequency between the LoRa terminal and the LoRa server becomes lower, and communication failures are prone to occur.
