Design and implementation of 10 kV overhead line fault monitoring system based on LoRa

针对现有架空线路故障监测系统的远距离数据传输,由于GPRS网络的不稳定性,造成的稳定性与可靠性降低的问题,通过分析LoRa技术特点,提出将LoRa技术应用于10 k V架空线路故障监测系统的数据传输方案。介绍其网络框架结构,并设计了相应的硬件终端设备和软件程序,最后对系统进行了测试分析。实验结构表明,该方案具有通信距离远、功耗低、组网灵活、可靠性高的特点,具有广泛的应用前景。

Due to the instability of the GPRS network,the stability and reliability of the remote data transmission of the existing overhead line fault monitoring system are reduced. By analyzing the characteristics of LoRa technology,the data transmission scheme of applying LoRa technology to 10 kV overhead line fault monitoring system is proposed. The network frame structure is introduced,and the corresponding hardware terminal equipment and software program are designed. Finally,the system is tested and analyzed. The experimental results show that the proposed scheme has the advantages of long communication distance,low power consumption,flexible networking and high reliability,and has a wide application prospect.
