Method of monitoring to anticipate the triggering of an alarm
First Claim
Patent Images
1. A method of monitoring a signal representing the amplitude of a predetermined physical value to trigger an alarm if the amplitude of the signal cross a predetermined threshold, wherein:
- (a) an historical profile is available which represents historical values of the signal over a predetermined period;
(b) the historical profile is used to estimate the future development of the signal as a function of its values during past time periods, thereby obtaining an estimated value of the signal during at least one future time period;
(c) the estimated value of the signal is compared for the at least one future time period to the threshold; and
(d) an alarm is triggered if the estimated value is higher than the threshold.

Abstract
A method of monitoring to anticipate the triggering of an alarm, wherein: an awaited profile is available which represents awaited values of the signal over a predetermined period; the awaited profile is used to estimate the future development of the signal as a function of its values on past dates; the estimated value of the signal is compared for at least one future date at a threshold; and an alarm is triggered if the estimated value is higher than the threshold.
