Abstract

The invention discloses an RFID label chip circuit that prevents reuse after being torn, comprising: a label chip, including a label protocol processing circuit and a tear detection circuit, and the label protocol processing circuit is used to complete voltage doubling and rectification, protocol control, information storage, etc. and realize the tear detection of the label according to the detection result of the tear detection circuit, the tear detection circuit is used to output the detection result to the label protocol processing circuit according to the DC voltage output by the rectification circuit of the analog circuit of the label chip The antenna is connected to the label protocol processing circuit and the tearing detection circuit, and is used to send and receive radio frequency signals and provide tearing trigger information. Through the present invention, the RFID electronic label can be prevented from being reused after being torn and the RFID electronic label is not unique The problem.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an RFID tag chip circuit that prevents reuse after being torn. Background technique [0002] With the rapid development of the Internet of Things technology, RFID (Radio Frequency Identification, radio frequency identification) electronic tags with functions such as identification, item tracking, and information collection have been widely used in many fields such as industrial automation and commercial automation. RFID electronic tag is a non-contact automatic identification technology. It uses radio frequency signals to identify target objects and obtain relevant data. The identification work does not require manual intervention. As a wireless version of barcodes, RFID technology has waterproof, Antimagnetic, high temperature resistance, long service life, large reading distance, data on the label can be encrypted, storage data capacity is larger, storage...
