Method and device for counting the number of landings performed by an aircraft tyre
First Claim

1. A method for counting a number of landings of an aircraft tyre, the method comprising steps of:
- intermittently measuring, in a discontinuous mode at regular intervals of time during the measuring, a physical quantity of air contained inside the tyre, the measuring being performed using a controller and beginning a sequence of measurements of the physical quantity when an initiation of tyre movement is detected, and ending the sequence of measurements when no tyre movement is detected;
determining at least one indicator relating to the physical quantity;
comparing the at least one indicator with a predetermined threshold associated with the tyre;
if the at least one indicator is determined to be greater than the predetermined threshold associated with the tyre, incrementing a stored number of landings of the tyre; and
after the stored number of landings of the tyre has been incremented, preventing the stored number of landings of the tyre from being incremented again until the at least one indicator is determined to have fallen below the predetermined threshold.

Abstract
A number of landings of an aircraft tire is counted according to a method that includes: measuring a physical quantity of air contained inside the tire, the measuring taking place in a discontinuous mode; determining at least one indicator relating to the physical quantity; comparing the at least one indicator with a predetermined threshold associated with the tire; and, if the at least one indicator is greater than the predetermined threshold associated with the tire, incrementing the number of landings of the tire.

5. A device for counting a number of landings of an aircraft tyre, the device comprising:
-
detection means for detecting an initiation of movement of the tyre; measurement means for discontinuously and intermittently measuring at regular intervals of time a physical quantity of air contained inside the tyre, the measuring means being controlled by a controller, wherein the controller controls the measurement means such that a sequence of measurements of the physical quantity begins when an initiation of tyre movement is detected by the detection means and ends when no tyre movement is detected by the detection means; determination means for determining an indicator relating to the physical quantity; comparison means for comparing the indicator with a predetermined threshold associated with the tyre; and incrementation means for incrementing a stored number of landings of the tyre, if the indicator is greater than the predetermined threshold, wherein, after the incrementation means increments the stored number of landings of the tyre, the controller prevents the stored number of landings of the tyre from being incremented again until the indicator is determined to have fallen below the predetermined threshold. - View Dependent Claims (6, 7, 8, 9, 10)

11. A device for counting a number of landings of an aircraft tyre, the device comprising:
-
a sensor that detects an initiation of movement of the tyre; a probe that discontinuously and intermittently measures at regular intervals of time a physical quantity of air contained inside the tyre; and a computer controller programmed to; activate the probe to perform measurements, determine an indicator relating to the physical quantity, compare the indicator with a predetermined threshold associated with the tyre, and, if the indicator is greater than the predetermined threshold, increment a stored number of landings of the tyre, wherein the controller activates the probe such that a sequence of measurements of the physical quantity begins when an initiation of tyre movement is detected by the sensor, and deactivates the probe such that the sequence of measurements ends when no tyre movement is detected by the sensor, and wherein, after the stored number of landings of the tyre has been incremented, the controller prevents the stored number of landings of the tyre from being incremented again until the indicator is determined to have fallen below the predetermined threshold. - View Dependent Claims (12)
