Development of the Monitoring System for the Stress State of Power Cable Laying Based on LoRa Wireless Spread Spectrum Technology

With the accelerated development of the power grid industry, the degree of dependence of power equipment on cables has gradually increased. Stress monitoring during the cable construction process is an important measure to ensure its safety. An online monitoring stress system with long-distance wireless transmission is designed in this paper. The whole system takes LoRa and online monitoring as the most critical technologies to achieve long-distance wireless data transmission, simplifies the secondary wiring of the monitoring system at the construction site, and overcomes the shortcomings of traditional short-distance wireless sensing technologies during the cable construction process. The feasibility of this system is verified by building an experimental platform. This research provides theoretical and technical support for the application of long-distance wireless transmission technology at the cable construction site.
