Design and Realization of Intelligent Monitoring and Protection System for Cable Status Based on IoT

In order to improve the operational safety of cables in complex environments, this study designs a cable condition monitoring system based on Internet of Things (IoT) technology, with real-time monitoring, data transmission, intelligent protection and automatic fire extinguishing functions. The system integrates a variety of high-precision sensors, which can collect key parameters such as temperature, humidity, current and partial discharge, and transmit them to the cloud platform through 4G network to realize remote real-time monitoring. In terms of protection design, new polymer composite materials are used to improve the reliability of the system in high temperature, high humidity and vibration environments. At the same time, the automatic fire extinguishing module can respond quickly when a fire occurs to ensure the safety of the system equipment. Experimental test results show that the system exhibits significant advantages in data transmission stability, power consumption control and protection performance under extreme conditions, providing strong support for the safe operation of power cables.
