Optimization Design on LoRa Communication Low Power Networking Control Technology for Power Grid Infrastructure Construction Sites

针对LoRa通信中的随机接入信道拥塞问题,本文提出一种基于存取类别限制技术的LoRa通信优化控制方法。仿真实验结果显示,按照该方法获取的存取类别限制最佳因子进行LoRa通信,网络中顺利接入的最大终端数量为23.84个,高于所有对比模型,且与理论值最为接近。该方法在仿真LoRa通信中最大程度地减少了信道拥塞造成的终端接入失败数量,有利于提升电网基建现场的LoRa通信质量。

Address the problem of random access channel congestion in LoRa communication,this paper proposes a LoRa communication optimization control method based on access category restriction technology.The simulation experiment results show that according to the optimal factor of access class restriction found by this method for LoRa communication,the maximum number of smoothly connected terminals in the network is 23.84,which is higher than all comparison models and closest to the theoretical value.That is to say,this method minimizes the number of terminal access failures caused by channel congestion in simulating LoRa communication,which is beneficial to improving the quality of LoRa communication on power grid infrastructure sites.
