Design of Transmission Line Lightning Monitoring System Based on LoRa Technology

For the lightning monitoring system of transmission lines, the issue of significant energy waste and reduced sensor lifespan arises from the continuous 24-hour operation of monitoring equipment. Additionally, due to China's transmission lines spanning many remote mountainous areas, there are challenges related to long transmission distances and poor signal quality. This paper proposes a design method for transmission line lightning monitoring system based on Long Range Radio (LoRa) wireless technology. This method aims to extend the data transmission distance in remote areas and reduce data transmission power consumption, while also modifying the working mechanisms of monitoring equipment and sensors to significantly lower power consumption. Experimental results demonstrate that this design scheme substantially reduces power consumption of the lightning monitoring system. While ensuring data accuracy, it also significantly enhances the data transmission distance.
