Aiming at the characteristics of various types of sensors,complex protocols,and wide distribution in the Internet of Things,a data transmission system for the Internet of Things based on 5G and LoRa is designed.Firstly,a data collector is designed with STM32,LoRa module and W5500 chip as the core,which can provide users with a simple data access device that can realize long-distance and easy networking.The edge gateway is designed with LoRa module,Raspberry Pi CM4 and 5G module as the core,which can aggregate and upload data from the data collector.Secondly,the Internet of Things is designed to connect to the cloud platform for collecting,configuring and visualizing terminal node information.After system testing,the system function and performance are stable and reliable,and it has broad application value in data collection and remote monitoring IoT application scenarios.
