Description

A New RFID Tire Electronic Tag

technical field

The utility model relates to the fields of rubber machinery and electronic information, in particular to a novel RFID tire electronic tag.

Background technique

Radio frequency identification (RFID) system is a non-contact identification system, which can attach small-sized chips to various items, and use radio frequency to transmit and process information about items; it generally includes An RFID electronic tag and a reader for reading item information stored in the RFID electronic tag, wherein the RFID electronic tag has a chip and an antenna connected to the chip. When in use, attach the RFID electronic tag to the surface of the item or insert it into the item, and the real-time information of the item can be detected in real time.

It can be seen that with the development of the information age, the technology of applying radio frequency identification (RFID) system to tires to monitor the tire usage status in real time has become the development trend of today's tires. At present, when the existing RFID electronic tags are implanted into tires, due to the relatively high vulcanization temperature (250°C) and the pressure in the vulcanization tank (>30Bar) during the carcass vulcanization process, the RFID electronic tags are very easy to install under such harsh installation conditions. In addition, the RFID electronic tag itself has a certain thickness, and it is easy to form air bubbles during the tire vulcanization process. If there are air bubbles in the tire, the safety factor of the tire will be greatly reduced.
