摘要
文章研究了LoRa技术的特点和优势,分析LoRa技术在煤矿中的应用方式和方法。研究结果表明:LoRa技术作为物联网低功耗远程通信技术,采用扩频调制等多项技术,实现低功耗下的远距离通信,具有远距离组网、低功耗、低成本、低速率和大规模的特点;它可以透传、私有协议和LoRaWAN协议等多种方式组网,实现远程组网通信;特别是针对远距离低速率组网方面,LoRa技术是目前十分理想的解决方案。
The characteristics and advantages of LoRa technology are studied,and the application method of LoRa technology in coal mines is analyzed. LoRa technology,as a low power remote communication technology of the Internet of things,uses a number of techniques, such as spread spectrum modulation, to achieve long distance communication under low power consumption. It has the characteristics of long distance networking,low power consumption,low cost,low rate and large scale. It can organize network through remote transmission, private protocol and LoRa WAN protocol to realize remote networking communication. Coal industry has used a large number of wireless networks to achieve such applications as monitoring,positioning and communication, but various technologies( such as Zig Bee network) have many problems,especially for the long range low rate network,LoRa technology is a very ideal solution.
