Internet of things communication method, device and storage medium based on lora technology

Abstract

The invention discloses an Internet of Things communication method, device and storage medium based on LoRa technology, belonging to the technical field of Internet of Things communication. The method includes acquiring data information sent by a LoRa terminal at a preset transmission rate, determining a maximum transmission rate corresponding to a target signal-to-noise ratio and a target signal strength, and sending the maximum transmission rate as a first predicted transmission rate to the LoRa terminal. And then receiving the data information sent by the LoRa terminal based on the first predicted transmission rate, so as to realize communication with the LoRa terminal. The present invention obtains the target signal-to-noise ratio and the target signal strength sent by the LoRa terminal, and sends the maximum transmission rate corresponding to the target signal-to-noise ratio and the target signal strength as the first predicted transmission rate to the LoRa terminal, so that it can be based on the first prediction The transmission rate is used to communicate, thereby reducing the communication time, so as to reduce the power consumption of the communication network with 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...

AI Technical Summary

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.
