Method for counting revolutions of a wheel

Abstract

The invention relates to a method for counting revolutions of a wheel (6) to which a target (7) is attached, the counting method comprising the step of: generating an oscillating signal representing the presence or the absence of the target (7); comparing an amplitude of the signal with a voltage threshold in order to obtain pulses (19); and detecting the presence of the target (7) or the absence of the target on the basis of the number of pulses obtained. The method also comprises a step of detecting a disruption which is implemented as feedback and which consists in acquiring differential pulse values each equal to a difference between two numbers of pulses obtained during two consecutive detection intervals, and in detecting a disruption upon identifying an erroneous sequence of consecutive differential pulses. A consumption meter and a computer program corresponding to the method and means for storing such a program are also claimed.
