LoRa-based Communication Technology for Overhead Line Internet of Things

Abstract

Internet of Things technology improves the state awareness level of power grid equipment through large-scale sensor collaboration and information communication network. In this paper, the application of LoRa low power wide area interconnection of things communication technology in overhead line state perception is studied. LoRa-based three-tier network architecture of low-power wide-area interconnection of things for overhead lines is proposed.This paper analyzed the communication and encryption between sensors and communication modules, communication modules and base stations, base stations and base stations. A design scheme of miniaturized state-aware device for overhead line based on LoRa is proposed. Two scenarios of application of LoRa-based state-aware technology for overhead line are listed, which can provide guidance for the popularization and application of the technology of Internet of Things for power equipment.
