Abstract
A device for determining the position of a moving part, particularly to a device containing a sensor carried by the moving part and designed to supply two out-of-phase signals, each assuming alternately the value 0 or 1 as the sensor is carried in one or the other direction. The device also has means of supplying pulses (ZD), each of which corresponds to one step forward on the part of the sensor, when the sensor moves in one direction, means of supplying other pulses (ZC), each of which corresponds to said step forward, when the sensor moves in the other direction, an up-down counting unit, means of transmitting the second pulses to an upcounting input belonging to the up-down counting unit, means of transmitting the first pulses to a downcounting input belonging to the up-down counting unit when the unit is not at zero and of blocking the downcounting input to said first pulses when the up-down counting unit is at zero, and means of transmitting said first pulses to a consuming device when the up-down counting unit is at zero and of blocking the consuming device to said first pulses when the up-down counting unit is not at zero.
