基于树莓派的远距离LoRaWAN网关系统设计与实现

Design and Implementation of Remote Lo Ra WAN Gateway System Based on Raspberry Pi

针对低功耗远距离的物联网网关系统,本文提出了一种以树莓派作为核心处理器,SX1301作为网关集中器的LoRaWAN网关系统。采用LoRaWAN协议,网关系统实现终端与服务器间上行数据、下行数据的传输与命令控制。通过对LoRaWAN网关的配置可实现远距离低功耗的数据传输,并与采用Zigbee协议的系统进行比较分析。实际测试结果表明,本文提出的基于树莓派的远距离LoRaWAN网关系统在近距离的墙体穿透能力和远距离通讯的抗干扰能力方面都有较好的效果。

To solve the problem of low-power long-distance IoT gateway design, this paper proposes a LoRaWAN gateway system with Raspberry Pi as the core processor and SX1301 as the gateway concentrator.Using the LoRaWAN protocol, the gateway system implements the transmission and command control of the uplink data and downlink data between the terminal and the server.Through the configuration of the LoRaWAN gateway, long-distance low-power data transmission can be realized and compared with systems adopting the Zigbee protocol.The actual test results show that the long-distance LoRaWAN gateway system based on Raspberry Pi proposed in this paper has a good effect on the wall penetration ability and the anti- interference ability of long-distance communication.
