Intelligent Highway Column Roadside Perception System Based on LoRa+5G Edge Gateway

该文设计了一种基于高速公路路侧护栏布设的智能立柱预警系统,系统基于LoRa无线通信和5G边缘网关的物联网数据传输,以GD32F303CGT6微处理器、LoRa通信模块和若干感知模块构成智能立柱节点,以RK3588微控制器、LoRa通信模块和移远通信5G模块RM500Q构造5G边缘网关,具有低成本、低功耗、广覆盖的特点.系统能够为现有高速公路全路网提供全面、实时、精准、可靠的事故报警、灯光预警、数据采集、救援跟踪等服务.

Roadside perception system is the key technology of intelligent highway construction.In view of the current demand for accident risk prediction and alarm on highways,and in order to build the comprehensive perception ability of the roadside perception system,this paper designs an intelligent column warning system based on the layout of the highway side guardfence.The system is based on LoRa wireless communication and 5G edge gateway data transmission of the Internet of Things.The intelligent column node is formed by GD32F303CGT6 microprocessor,LoRa communication module and several perception modules,and the 5G edge gateway is constructed by RK3588 microcontroller,LoRa communication module and 5G module RM500Q.It has the characteristics of low cost,low power consumption and wide coverage.The system can provide comprehensive,real-time,accurate and reliable accident alarm,light warning,data acquisition,rescue tracking and other functions for the existing highway network.
