| Abstract:Traditional RFID technology applied in electric energy metering equipment management suffers from impedance mismatch in metal environments, low reading efficiency of stacked multiple tags and high operation and maintenance costs. This paper proposes an UHF-RFID intelligent recognition system integrated with a novel anti-metal tag antenna. The tag antenna is designed with double ground plane and coupled feeding structure, and spiral ring slots are arranged with geometric parameters optimized to broaden impedance matching bandwidth and improve radiation performance. A three-layer framework including perception, transmission and application is established, and dynamic framed slotted anti-collision algorithm is adopted at the perception layer to realize rapid inventory of mass stacked metering equipment. Experimental results verify that the proposed antenna has excellent return loss performance, and the system achieves high tag reading accuracy and shelf positioning success rate. The technology effectively improves recognition accuracy and reliability of electric energy metering assets in harsh environments, and provides technical support for large-scale application of power Internet of Things. |
