Abstract
A method, system and computer program product are provided for implementing tire tread depth and wear patterns monitoring. A radio frequency identification (RFID) tag is provided with an associated tire to be monitored. A dipole antenna structure is coupled to the RFID tag and routed within a position in the tire tread and routed substantially circumferentially in the associated tire. A resonant frequency of the dipole antenna structure is detected to monitor tire tread wear.
Claims16
A system for implementing tire tread depth and wear patterns monitoring of a tire comprising:
- a radio frequency identification (RFID) tag;
- a dipole antenna structure disposed in a portion of the tire;
- a tire tread wear monitoring control logic,
- wherein the tire tread wear monitoring control logic tangibly embodied in a non-transitory machine readable medium configured to implement tire tread monitoring;
- wherein the tire tread wear monitoring control logic is configured to process inputs from the RFID tag and the dipole antenna;
- wherein the tire tread wear monitoring control logic is configured to detect a resonant frequency of the dipole antenna structure to monitor tire tread change based on the processed inputs;
- and
- wherein the dipole antenna structure is coupled to the RFID tag and includes more than one antenna, with the RFID tag detecting resonant frequency changes to monitor one of point wear and are wear in tire tread.
A method for implementing tire tread depth and wear patterns monitoring of a tire comprising:
- providing a radio frequency identification (RFID) tag coupled to a dipole antenna structure with an associated tire to be monitored;
- providing the dipole antenna structure with four antenna, and wherein the RFID tag detects resonant frequency changes to monitor ripple wear in tire tread,
- providing a dipole antenna structure disposed in a portion of the tire;
- providing a tire tread wear monitoring control logic,
- wherein the tire tread wear monitoring control logic tangibly embodied in a non- transitory machine readable medium configured to implement tire tread monitoring;
- wherein the tire tread wear monitoring control logic, processes inputs from the RFID tag and the dipole antenna;
- and
- wherein the tire tread wear monitoring control logic, detects a resonant frequency of the dipole antenna structure to monitor tire tread change based on the processed inputs;
- and
- wherein said radio frequency identification (RFID) tag is mounted within a non-tread portion of the tire.
