基于LoRa的矿用无线通信系统设计

    Design of mine wireless communication system based on LoRa technology

    • 摘要: 为解决传统煤矿监控系统传感层有线总线通信节点容量少、通信距离短、布线成本高等问题,设计了一种基于LoRa的矿用无线传感层通信系统,实现监控区域网络全覆盖。详细介绍了系统网关和终端通信模块设计,终端入网机制,通信地址管理,网关容量与信道分配管理,信道划分与漫游机制。现场实验表明:设计的系统组网灵活,通信距离远,链接可靠性高,满足煤矿井下传感层无线通信需求。

       

      Abstract: In order to solve the problems of low capacity, short communication distance and high wiring cost of wired bus communication node of sensor layer in traditional coal mine monitoring system, a communication system of wireless sensor layer for mine based on LoRa was designed to realize full coverage of monitoring regional network. The system gateway and terminal communication module design, terminal network access mechanism, communication address management, gateway capacity and channel allocation management, channel division and roaming mechanism are introduced in detail. Field experiments show that the designed system has the advantages of flexible networking, long communication distance and high link reliability, which can meet the demand of wireless communication of sensing layer in underground coal mine.
