Design of Online Monitoring System for High-voltage Power Transmission Equipment Based on LoRa Technology

Abstract

The real-time transmission of online monitoring data for high-voltage transmission equipment in remote areas is a difficult problem in practical applications due to the lack of network. For this purpose, the article designs an online monitoring system for high-voltage transmission equipment based on ubiquitous IoT and LoRa technology. It constructs a low-power, long-distance LoRa wireless communication self-organizing network, transmits the transmission equipment status information and other data collected by front-end sensors to the LoRaWAN gateway, and then uploads the data to the back-end server through a 5G wireless network to achieve the overall communication link of the online monitoring system. The simulation experiment results show that compared with the existing technical solutions ZigBee, LoRa, and NB-IoT, using the scheme designed in the article, the system transmission speed (20-100 kbit/s) is the fastest, and the packet loss rate, transmission delay, and average time consumption (1.6%, 0.27s, and 60s, respectively) are the lowest. This indicates that the system not only has a fast transmission speed but also takes into account the characteristics of low power consumption and long distance, achieving stable data transmission, and is suitable for online monitoring of high-voltage transmission equipment in remote areas.
