Low-voltage transformer security system and method based on radio frequency encryption technology

Abstract

The invention provides a low-voltage transformer security system and method based on radio frequency encryption technology. The security system comprises radio frequency electronic tags, tag readers-writers, a low-voltage transformer and a backstage management system. The radio frequency electronic tags are installed on the low-voltage transformer. The tag readers-writers conduct information interaction with the radio frequency electronic tags through RFID signals, and conduct information interaction with the backstage management system through communication channels. According to the radio frequency electronic tag ID and the low-voltage transformer relevant information, a corresponding verification code of the low-voltage transformer is calculated through an SM7 encryption algorithm so that the low-voltage transformer can be subjected to unique identification and verification in the whole life cycle. The radio frequency electronic tag in the security system is easily damaged in installation and removal and has the functions of data encryption, identity authentication, location sensing and the like, and the security system has better security effects as compared with a conventional system.

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.
