WIRELESS COMMUNICATION TERMINAL HAVING TIRE PRESSURE MEASURING FUNCTION AND METHOD THEREOF, CONCERNED WITH INCREASING MEASUREMENT STABILITY WITHOUT BEING AFFECTED BY ELECTROMAGNETIC WAVE

摘要

PURPOSE: A wireless communication terminal having a tire pressure measuring function is provided to measure the pressure of a tire by using an optical fiber sensor, and to output the measured result on a display device or to transmit the result, thereby increasing measurement stability without being affected by an electromagnetic wave. CONSTITUTION: An operation/control device(12) operates an optical fiber sensor(19) according to a tire pressure measurement request signal, receives an electrical signal corresponding to a tire air pressure, and generates tire pressure measurement results. The optical fiber sensor(19) applies a reference light to an optical fiber grating(194), receives a reflected light in accordance with the tire air pressure to convert the reflected light into an electrical signal, and transmits the electrical signal to the operation/control device(12). An LCD(16) outputs tire pressure measurement results. A storage(14) stores a program, a file system, and a tire pressure measurement result generation program.
