Abstract
PURPOSE: To highly accurately calculate the diameter of a wheel by dividing the distance by the number of pulse signals which are proportional to the rpm of the wheel counted during the run.
CONSTITUTION: The wheel diameter compensator is composed of: a tachometer 1 for generating signals of a frequency proportional to the rpm of a wheel; a waveform shaping circuit 2 for converting the signals of the tachometer 1 into pulse signals; a receiving circuit 3 for receiving the carrier wave signals of an ATC device from the grouns and for detecting the change in the frequency of the carrier waves thereby to generate signals; and a memory arithmetic circuit 4 for memorizing the distance between points A and B and the number of appearances of the respective carrier waves, at which the wheel diameter compensating section changes the frequency. In the circuit 4, the detected signals are counted between the point A to the point B, and the number n of the detected signals until the memorized numbers are counted are counted, and the distance is divided by the number n thereby to calculate the wheel diameter.
