Automatic recognition and tread-pattern depth warning system for tire by using mileage

The invention discloses an automatic recognition and tread-pattern depth warning system for a tire by using mileage. The automatic recognition and tread-pattern depth warning system comprises a tire body and a revolution counting device, wherein the revolution counting device comprises a sensor for counting cumulative revolutions in the life cycle of the tire, an MCU, a wireless transceiver circuit and a nonvolatile memory; the sensor, the MCU, the wireless transceiver circuit and the nonvolatile memory are all adhered to the lining surface of the tire body; the sensor, the wireless transceiver circuit and the nonvolatile memory are electrically connected with the MCU. The automatic recognition and tread-pattern depth warning system disclosed by the invention has the beneficial effects that after the MCU performs filter shaping on pulse signals of the sensor, the pulse signals are accumulated and counted and then are stored into the nonvolatile memory of the sensor; data of deformationaccumulation times, stor
