嵌入式Linux的LoRaWAN集成网关系统设计
资料介绍
针对小规模LoRa网络建设成本偏高的问题,提出了基于嵌入式平台的LoRaWAN集成网关系统。该网关系统在单一嵌入式硬件(树莓派)上同时集成了网关的所有功能和LoRaWAN服务器的功能,避免了部署专门服务器,降低了系统成本,提高了部署灵活性。为了提高LoRa网络的覆盖范围和网络的稳定性,系统可同时部署多个集成网关,一个节点可同时被多个网关覆盖。本文提出主从式集成网关的解决方案,每个从网关能分担系统的运算负荷,提升系统性能,且数据库备份于多个网关上,增强了数据库的安全性。实验结果表明,本方案具有覆盖面积广、成本低廉、扩展性好、安全性高、并发性能好的特点。
Aiming at the high cost of small-scale LoRa network construction,the LoRaWAN gateway system based on embedded platform is proposed.The gateway system integrates all gateway functions and LoRaWAN server functions simultaneously on a single embedded hardware (Raspberry Pi).This solution reduces system costs and improves deployment flexibility.In order to improve LoRa network coverage and network stability,the system can deploy multiple integration gateways at the same time,and a node can be covered by multiple gateways at the same time.A master-slave gateway system solution is proposed,the slave can share the computing load of the system and improve system performance.The database is backed up on multiple gateways,which increased database security.The experiment results show that the proposed scheme has the characteristics of wide coverage,low cost,good expansibility,high security and good concurrency.
