摘要
为了实现低功耗、长距离和广域无线通信,根据LoRaWAN规范和协议,提出了一种基于树莓派CM3和STM32微处理器的LoRaWAN网络的设计方案,并开发和实现了基于STM32和SX127x为射频前端的远距离低功耗LoRaWAN节点设计,以及实现了搭载Linux系统的树莓派CM3和SX1301射频前端构成的LoRaWAN通信网关的设计,同时,依此搭建了服务器网络测试平台,实现了广域无线网络设备之间的互联互通以及设备运行状态的实时监测.该方案对广域无线网络的实际应用落地具有参考意义.
Abstract
In order to achieve low power consumption,long distance and wide area wireless communication,accord-ing to the LoRaWAN specification and protocol,a design scheme of LoRaWAN network based on Raspberry Pi CM3 and STM32 microprocessor is proposed,and a LoRaWAN network based on STM32 is developed and implemented.and SX127x are long-distance low-power LoRaWAN node designs for RF front-ends,and the design of LoRaWAN communication gateway composed of Raspberry Pi CM3 equipped with Linux system and SX1301 RF front-end.At the same time,a server network test platform was built based on this to achieve It provides interconnection between wide-area wireless network devices and real-time monitoring of device operating status.This solution has reference significance for the practical application of wide area wireless networks.
