基于LoRa的数据中继传输通信方法

Data Relay Transmission Communication Method Based on LoRa

针对单LoRa网关产品在地下隧道布设时蜂窝网络覆盖不完全导致网关与云端通信不可靠、网线布设成本较高的问题,从应用角度设计并实现了一种应用于网关产品之间数据中继传输的通信方法。该方法在支撑数据正常交互的同时,能够相对及时地将异常终端进行上报,亦能够避免网关数据积压,在一定程度上解决了隧道环境下网关的布设问题,使LoRa产品的适用性得到了一定程度的提高。实验结果验证了该通信方法的可行性。

Aiming at the problems of unreliable communication between gateway and cloud due to incomplete cellular network coverage and high cost of network cable deployment encountered by single Lora gateway products in underground tunnel deployment,a communication method applied to data relay transmission between gateway products is designed and implemented from the perspective of application.This method can support normal data interaction as well as report abnormal terminals in a relatively timely manner,and can also avoid the backlog of gateway data,which to a certain extent solves the problem of gateway deployment in a tunnel environment and improves the applicability of Lora products.Experimental results verify the feasibility of this communication method.
