A low-voltage transformer anti-counterfeiting system and method based on radio frequency encryption technology

Abstract

The invention provides a low-voltage transformer anti-counterfeiting system and method based on radio frequency encryption technology. The anti-counterfeiting system includes a radio frequency electronic tag, a tag reading and writing device, a low-voltage transformer and a background management system; the radio frequency electronic tag is installed on the low-voltage transformer. The writing device performs information interaction with the radio frequency electronic tag through the RFID radio frequency signal, and performs information interaction with the background management system through the communication channel. According to the RF electronic tag ID and the relevant information of the low-voltage transformer, the corresponding low-voltage transformer check code is calculated through the SM7 encryption algorithm so that the low-voltage transformer can be uniquely identified and verified throughout the entire life cycle. In addition, the RF electronic tag in the anti-counterfeiting system is Electronic tags that are easy to disassemble and wear, and have functions such as data encryption, identity authentication, and position sensing, have better anti-counterfeiting effects than traditional systems.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, and in particular relates to a low-voltage transformer anti-counterfeiting system and method based on radio frequency encryption technology. Background technique [0002] In our country, power users are relatively diversified, and some users use various means to destroy or interfere with the normal operation of power metering equipment in order to pursue high profits and steal electricity. Among them, methods such as replacing the low-voltage transformer and changing the nameplate of the transformer are more commonly used methods of stealing electricity. In order to prevent the frequent occurrence of power theft incidents, the research on the anti-counterfeiting technology of low-voltage transformers is very important. The application of electronic tags on low-voltage transformers can detect counterfeiting and illegal destruction of low-voltage transformers by unauthorized...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the characteristics of low power consumption, limited storage space and computing power, the electronic tags used on most transformers cannot perform some complex cryptographic operations, making the device information easy to be illegally deciphered, and some electronic tags are very Easy to separate from the transformer, which makes the risk of illegal counterfeiting or replacement of the transformer still exists

Therefore, the existing anti-counterfeiting technology based on electronic tags has security defects to a certain extent, and the anti-counterfeiting effect cannot reach the expected goal.
