Design of an Intelligent Ground Wire Identification Device Based on IoT and RFID Technologies

The accuracy of existing ground wire position identification devices is often compromised due to electromagnetic interference. To address this issue, this paper proposes an intelligent recognition device that integrates radio frequency identification (RFID) technology with ultra-wideband (UWB) positioning. By leveraging the broad spectrum of UWB signals to disperse energy, the system effectively reduces electromagnetic interference and enhances positioning accuracy. Experimental results demonstrate that the positioning error remains consistently within the range of 0.06–0.1 m. Even in environments with significant electromagnetic interference, the increase in error is minimal, indicating strong anti-interference performance. The device proposed in this paper, which utilizes RFID-UWB technology, significantly improves the precision of ground wire positioning and offers robust technical support for intelligent identification tasks requiring high accuracy.
