Design of RFID Power Tag for Electrical Equipment Against Electromagnetic Interference

RFID power tags of traditional power tools cannot work normally in a strong electromagnetic interference environment, which can easily lead to tag damage and information leakage. In response to the above problems, this paper designs an RFID power tag that resists electromagnetic interference. The RFID power tag housing uses anti-interference materials and high insulation and voltage-resistant packaging. The tag uses a STM32L4 microcontroller and a two-stage filtering algorithm based on Kalman filtering is proposed. The data transmission uses UHF, which achieves a good anti-electromagnetic interference and anti-noise effect. In addition, the communication between the tag and the reader uses a physical unclonable function based on the fingerprint of the devices physical characteristics for encryption. Finally, it is verified by experiments that the RFID tags designed in this paper can not only resist strong electromagnetic interference, but also prevent information leakage, and can be well applied in complex power environments.
