TIRE WEAR SENSOR SYSTEM USING RFID |
摘要 |
A system for monitoring wear of a vehicle part is disclosed. The system comprises a piezoelectric disk (210) electrically connected to a radio frequency circuit (220) for receiving electrical current from the piezoelectric disk (210); and an antenna (230) for transmitting a signal from the radio frequency circuit (220) to a microprocessor (240) such that, when the piezoelectric disk (210) contacts a surface through wear, the radio frequency circuit (220) generates a signal received by the microprocessor (240). Preferably, the vehicle part is a tire (44) and the at least one RFID tag (10, 38, 42) includes a plurality of RFID tags in preferably each tire (44) of the vehicle embedded at different tread depths. |
