Abstract
A method of monitoring at least one tire condition value of each of a plurality of tires of a moving vehicle, with a monitoring system. Each of the tires has an electronic tire tag for sensing the tire condition value of the associated tire. The monitoring system has vehicle sensing apparatus, ramp apparatus, tire sensing apparatus, transceiver apparatus and computer apparatus removably electrically connected thereto and to the vehicle sensing apparatus and tire sensing apparatus. The method comprises the steps of determining whether the vehicle sensing apparatus has sensed the moving vehicle on the ramp apparatus supporting the moving vehicle. In addition the method includes the steps of determining whether respective tires of the moving vehicle have been sensed by the tire sensing apparatus, and transmitting an interrogation signal when the tire sensing apparatus senses at least one tire. Further, the method includes the step of receiving and demodulating modulated tire tag signals independently of one another from different tire tags for providing different demodulated tire tag signals. Moreover, the method includes the step of digitizing the different demodulated tire tag signals and providing corresponding different digital tire tag signals to the computer apparatus.
