Abstract

An intelligent tire includes a tire body, a sheet-shaped conductive polymer Sensor, a micro control unit, an RF unit, an upper computer, and an RF circuit The sheet-shaped conductive polymer sensor is affixed to an inner liner layer at a middle portion of a tire crown. One end of the sheet-shaped conductive polymer sensor is connected to the micro control unit through the RF unit, and the other end of the sheet-shaped conductive polymer sensor is connected to the upper computer through the RF circuit. A processor is electrically connected to a power supply module, and the processor is connected to and controls a display screen and an audible alarm. A communication port is interconnected to the processor. The state of the tire is comprehensively determined by matching or combining a strain amplitude of the tire crown and an operating temperature with a fitting function.

First claim

What is claimed is:

1 . An intelligent tire, comprising a tire body, a sheet-shaped conductive polymer sensor, a micro control unit, air RF unit, an upper computer , and an RF circuit, wherein the tire body is successively provided with a tire tread layer, a neutral layer and an inner liner layer from outside to inside; the sheet-shaped conductive polymer sensor is affixed to the inner liner layer at a middle portion of a tire crown; a first end of the sheet-shaped conductive polymer sensor is connected to the micro control in through the RF unit, and a second end of the sheet-shaped conductive polymer sensor is connected to the upper computer through the RF circuit; the upper computer comprises a power supply module, a communication port, a display screen, an audible alarm, a press-key input module, and a processor, wherein the processor is electrically connected to the power supply module, and the processor is connected to and controls the display screen and the audible alarm, the communication port is interconnected to the processor, and the press-key input module is connected to the processor.

2 . The intelligent tire according to claim 1 , wherein the sheet-shaped conductive polymer sensor is bonded to the inner liner layer by an adhesive.

3 . The intelligent tire according to claim 1 , wherein the sheet-shaped conductive polymer sensor is coagulated with the inner liner layer to form into one piece by low-temperature low-pressure vulcanization.

4 . The intelligent tire according to claim 1 , wherein the sheet-shaped conductive polymer sensor has a positive temperature effect and a positive tensile effect.

5 . The intelligent tire according to claim 1 , wherein a material of the sheet-shaped conductive polymer sensor is a conductive rubber.

6 . The intelligent tire according to claim 1 , wherein the RF circuit is a semi-active RFID.

7 . The intelligent tire according to claim 1 , wherein a working principle of the intelligent tire is as follows; since an impedance of the sheet-shaped conductive polymer sensor affixed to the inner liner layer at the middle portion of the tire crown of the tire body is affected by a temperature and a strain, in order to separate temperature and strain signals, the RF unit is controlled by the micro control unit to perform a frequency scanning on the sheet-shaped conductive polymer sensor; then, an impedance change of the sheet-shaped conductive polymer sensor is analyzed by a main cause analysis, and the impedance changes caused by the temperature and the strain are separated to obtain the temperature and strain signals; then, the sheet-shaped conductive polymer sensor transmits temperature and strain data of the temperature and strain signals to the upper computer through the RF circuit; the temperature and strain data of the temperature and strain signals are substituted into a fitting formula introduced by the communication port for calculating a danger coefficient, so as to obtain the danger coefficient of a tire during a drive; and when the tire is running in excess of a predetermined danger coefficient for more than a predetermined period of time, the upper computer alarms through the display screen and the audible alarm.
