摘要 目前市场上高压架空输电线路覆冰监测的难点在于覆冰状态特征的安全实时监测,设计了基于LPWAN的架空输电线路监测系统。为了保证该系统的安全实时性、信息传输的有效性和可靠性,采用了NB-IoT和LoRa技术相结合的低功耗收发模块,对多种传感器采集到的终端数据进行高质量传输;设计了系统监测终端的硬件和软件设计,以及对系统监测各模块进行牢固的安装设计。模拟试验结果表明,多元结合的无线传输方式与单一的无线传输方式相比较,数据传输丢包率有明显的降低。 At present,the difficulty in ice monitoring of high-voltage overhead transmission lines on the market lies in the safe real-time monitoring of the characteristics of the icing state,and the design of the overhead transmission line monitoring system based on LPWAN is designed.In order to ensure the security and real-time performance of the system,the validity and reliability of information transmission,a low-power transceiver module based on NB-IoT and LoRa technology is used to transmit high-quality terminal data collected by various sensors.The hardware and software design of the system monitoring terminal is designed,and the solid installation design of each module of the system monitoring is carried out.The simulation results show that,compared with the single wireless transmission mode,the packet loss rate of data transmission is significantly reduced.
