Intelligent RFID electronic tag capable of instantly perceiving enable state

Abstract

The invention provides an intelligent RFID electronic tag capable of instantly perceiving an enable state. The electronic tag at least comprises a tag antenna, a tag chip, and an enable perceiving sensing circuit, wherein a main controller, an antenna radio-frequency circuit, a memory and an enable perceiving sensing module are integrated in the tag chip; the enable perceiving sensing circuit is connected with the enable perceiving sensing module; two pins of the enable perceiving sensing module form a short circuit through the enable perceiving sensing circuit; when the RFID electronic tag is enabled or torn, the two pins connected originally form an open circuit in a way of physically destroying the enable perceiving sensing circuit, and enable information is obtained; the main controller receives the information of the enable perceiving sensing module and modifies data in the memory; and when a reader-writer reads the data in the memory, enable or destruction information can be obtained through an upper computer, and data stored in the original tag chip is not lost and can be normally read by the reader-writer.

Description

technical field [0001] The invention provides a method for making an intelligent RFID electronic label that can be perceived when it is opened. The electronic label can be automatically identified when it is opened or destroyed, and belongs to the technical field of RFID electronic labels and intelligent sensors. Background technique [0002] RFID electronic tags are the physical carrier of the electronic product code (EPC). They are attached to items to be tracked and can be circulated globally and identified, read and written. Currently, they are widely used in the field of logistics networks. In the application of commodity anti-counterfeiting and traceability projects, it is required that the electronic label can be discovered by the user in time after it is opened or torn off. The current anti-tear electronic tags all use the method of destroying the antenna. When the RFID tag is pasted on the item and is torn off, the antenna of the tag is damaged, making the tag info...

AI Technical Summary

Problems solved by technology

When the RFID tag is pasted on the item and is torn off, the antenna of the tag is damaged, making the tag information unreadable

But at the same time, the stored information in the original tag chip will also be unreadable

Therefore, after the existing anti-tear electronic label is torn off, it can be judged by the traceability system that the label is damaged, but it is impossible to trace back and read the item information contained in the original label.
