INTELLIGENT TIRE

An intelligent tire, including a tire body (1), a sheet-shaped conductive polymer sensor (5), a micro control unit (6), an RF unit (7), an upper computer (8), and an RF circuit (9). The sheet-shaped conductive polymer sensor (5) is affixed to an inner liner layer (4) at a middle portion of a tire crown. One end of the sheet-shaped conductive polymer sensor (5) is connected to the micro control unit (6) through the RF unit (7), and the other end of the sheet-shaped conductive polymer sensor (5) is connected to the upper computer (8) through the RF circuit (9). A processor (8-6) is electrically connected to a power supply module (8-1), and the processor is connected to and controls a display screen (8-3) and an audible alarm (8-4). A communication port (8-2) is interconnected to the processor (8-6). The intelligent tire is mainly designed for early warning of dangerous tire conditions. The state of the tire is comprehensively determined by matching or combining the strain amplitude of the tire crown and an operating temperature with a fitting function. The strain amplitude and the operating temperature can be simultaneously obtained by using the single conductive polymer sensor, so as to provide the early warning of various dangerous conditions of the tire. Moreover, the sheet-shaped conductive polymer sensor has a low cost and is readily popularized.
