基于LoRa的远距离数传系统的研究与设计

Research and Design of Long Distance Data Communication System Based on LoRa

针对复杂干扰的工作环境下导致的远距离通信效率低、可靠性低等问题,本文利用LoRa具有稳定、能耗低、覆盖广、易实施的特点,设计了一种低成本、高可靠性、高效率、高安全性的快速部署远距离通信系统。实验结果表明,该系统能量传输效率可达97.96%,在通信距离4千米情况下误码率仅有10%左右,同时在工业级温度下(-40℃~85℃)稳定工作而不影响数传效率。

In view of the low efficiency and low reliability of long-distance communication caused by complex interference environment,this paper designs a low-cost,high reliability,high efficiency and high security rapid deployment long-distance communication system by taking advantage of LoRa's characteristics of stability,low energy consumption,wide coverage and easy implementation.The experimental results show that the energy transmission efficiency of the system can reach 97.96%,and the bit error rate is only about 10%when the communication distance is 4km.At the same time,it works stably at industrial temperature(-40℃~85℃)without affecting the data transmission efficiency.
